The invention relates to a receiver shelf for satellite positioning. The receiver shelf comprises a disc, fixing frames, a connecting cylinder, a self-balancing mechanism and a fine adjustment mechanism; the fixing frames are uniformly arranged on the lower end face of the disc in the circumferential direction of the disc, and the connecting cylinder is installed on the upper end face of the disc;the connecting cylinder comprises three layers, the upper layer and the lower layer are of cube structures, and the middle layer is of a regular triangular prism structure; the interior of the connecting cylinder is of a hollow structure, and the self-balancing mechanism is arranged in the connecting cylinder; the upper end face of the connecting cylinder is provided with the fine adjustment structure; each fixing frame comprises a first supporting rod. The receiver shelf can solve the problems that when a traditional bubble leveling method is used for adjusting the levelness of a receiver, the horizontal accuracy is not high, the bubble movement sensitivity is not high, no horizontal reference exists during adjustment, adjustment needs to be repeated, and adjustment steps are complex; the high-precision level adjustment of the receiver can be realized, and the receiver shelf has the advantages of being high in accuracy, high in sensitivity and simple in adjustment process and havingthe horizontal reference.

The invention discloses a dust removal working table which comprises a working table body, a support and an air suction pipeline. The surface of the working table body is provided with a series of dust inlet holes. The air suction pipeline is located on one side of the working table body. The dust removal working table is characterized in that a transparent dust guard is arranged above the working table body, the obverse side of the dust guard is provided with a door curtain, dust hoods are arranged in the working table body, the dust hoods are in a straight triangular prism shape, and the two sides of each dust hood are provided with a series of dust collection holes. According to the dust removal working table, the negative-pressure working table surface is formed through an air exhaust fan, and the dust guard is arranged above the working table body, so dust formed in the working table can be collected in the dust guard and prevented from spreading in a whole workshop; besides, the three dust hoods are arranged in the working table body and designed into the straight triangular prism shape, so the contact area between the dust hoods and the dust can be greatly increased, and the dust collection efficiency is improved.

The invention discloses a multi-face LED lamp aluminum profile material and belongs to the field of LED lamp aluminum profile materials. The multi-face LED lamp aluminum profile material comprises a main frame and a cover plate. The main frame comprises a regular-triangular-prism-shaped support and side plates perpendicularly arranged on three side faces of the support. The support and the side plates are connected through an inserting-connecting mechanism. The inserting-connecting mechanism comprises inserting-connecting grooves formed in the three side faces of the support, and inserting-connecting pins arranged at one ends of the side plates. The inserting-connecting grooves comprise vertical strips and locking strips. The vertical strips are arranged oppositely and are perpendicular tothe side faces of the support. The locking strips are arranged on the faces, opposite to the two vertical strips, on each side face of the support. The locking strips comprise first locking strips and second locking strips away from the side faces of the support sequentially. A first locking cavity is formed between the first locking strips and the side faces of the support. A second locking cavity is formed between the second locking strips and the first locking strips. The thickness of the parts, provided with the first locking cavity, of the two vertical strips is larger than that of the parts, provided with the second locking cavity, of the two vertical strips. According to the multi-face LED lamp aluminum profile material, the inserting-connecting quantity of the side plates can be adjusted as needed so as to achieve multi-face illumination or single-face illumination, the inserting-connecting mechanism is high in stability, and disassembly and assembly are easy.

The invention relates to the field of textiles, in particular to a method for improving the harness winding efficiency in the textile process. The method comprises steps of S1 to S3. A winding machineadopted in the method comprises a pay-off mechanism, a shell, a machine body, a first motor, a first supporting plate, limiting columns, a sliding mechanism, a harness box, a second supporting plate,a drive mechanism, a take-up mechanism and a harness pushing mechanism. A triangular prism-shaped fixing column located in the pay-off mechanism and a clamping column of the take-up mechanism are equal in size, a bobbin can be directly clamped to the surface of the fixing column, the drive mechanism coordinates with the harness pushing mechanism to enable a harness needing to be wound to swing between the two limiting columns, the situation that the harness is taken up at one position of the surface of the bobbin is avoided, taking up is more uniform, the harness box is internally and fixedlyconnected with a sliding frame, the sliding frame is internally connected with a swinging block which is of a T-shaped structure in a sliding manner, the harness needing to be wound penetrates a harness hole located in the swinging block, a spring is arranged between the swinging block and the sliding frame and coordinates with the swinging of the harness pushing mechanism, and harness snapping from tension is avoided.

A dual-beam parallel inscribing apparatus based on axial chromatic aberration of a focusing lens comprises a first laser, a second laser, a first 1/2 wave plate, a second 1/2 wave plate, a first beam expander, a second bean expander, a first beam splitter, a second beam splitter, a first reflector, a second reflector, a third reflector, the focusing lens, a triangular prism, a first detector and a second detector. According to the present invention, two beams of light with different wavelengths are coupled into the same beam of light, the axial chromatic aberration is generated by the focusing lens, and the light is focused into different positions in the axial direction, i.e. the positions with different thicknesses on a photoetching material, so that simultaneous photoetching of double axial focuses is implemented. According to the dual-beam parallel inscribing apparatus, simultaneous storage of double beams can be implemented, the storage speed is doubled, the information storage capacity is also improved, and a basis is provided for popularization and application of a multilayer optical storage technology. The dual-beam parallel inscribing apparatus further has a real-time signal reading and inscribing system, thereby ensuring the inscribing accuracy.

The invention relates to a device for sterilization of microorganism culture dishes. The device comprises an outer breathable film, a sterilization barrel and a triangular prism support, wherein the sterilization barrel comprises a barrel cover and a barrel body; the outer breathable film is fixed on the outer surface of the barrel cover through a rubber band; and the triangular prism support is arranged in the barrel body. The device is simple in structure and saves space, steam sterilization and drying operation can be performed on the culture dishes conveniently, the sterilized culture dishes can be conveniently taken out as required, and the conditions that the sterilization does not succeed and the culture dishes are scattered and crushed are prevented.
