The invention provides a temperature-controllable electric field induction platform. The temperature-controllable electric field induction platform comprises a clamping portion, a temperature keeping portion and an electric field generation portion, wherein the clamping portion is arranged on a work platform (16) in the temperature keeping portion, temperature of a temperature control box of the temperature keeping portion is controlled through a temperature control heating system composed of a PID silicon controlled rectifier temperature control component (21), thermocouples (19) and (20) and ten sets of resistor heating components (18), and the electric field generation portion can generate a 50kV-voltage power frequency AC electric field and a DC electric field. The platform mainly satisfies requirements of a complete sulfuration process of preformed liquid state silicone rubber while being applied to electric field induction processing manufacturing, ordered arrangement is realized under the orientation induction action of the electric field, conductive particles of the conductive rubber are made to form a more effective flow path, the heating portion can provide a heat source for rubber sulfuration, and the platform can provide an external high-field-intensity field for the conductive rubber when influence of the external electric field on conductive performance of materials is tested.

The present invention provides an adjustable keyboard. The adjustable keyboard comprises a base casing, a support plate is formed at the lower portion of the base casing, the support plate is providedwith a circuit film, and one key hole with one built-in key is arranged above each switching node; each key comprises one key magnet, and the bottom portion of each key is provided with one conductive rubber; one adjusting nut is arranged at each of four corners of the base casing, the adjusting nuts can perform twist to adjust the lengths of screws stretching into the bottom portion of the basecasing, and the lower end of one nut of each adjusting nut is supported at a desktop; an adjusting plate is arranged below the base casing, sleeves the adjusting nuts through by employing holes arranged at the four corners, and horizontally laid at the upper ends of the nuts of adjusting nuts; and adjusting plate magnets having the same polarity being opposed to each other as one key magnet in each key are arranged on the adjusting plate facing each key. The adjustable keyboard can flexibly adjust the hardness when the keys are pressed down in the usage process so as to meet demands of different users in different scenes.
