AI Technical Summary

Benefits of technology

This patented technology uses a special device called a cylinders to create accurate measurements when measuring small objects like keys or buttons. These devices use compressed gases instead of traditional hydraulic systems, making them more reliable over longer periods without getting damaged due to their weight. They have various ways to control how much they compress into each unit space, allowing precise measurement even if there may be multiple tiny parts inside. By changing these settings, this new method allows researchers to study things faster while still ensuring accuracy compared to previous methods such as water drop tests.

Problems solved by technology

This patented technical problem addressed by this patents relates to reducing damage caused during use on small keys made from materials like metal because they can cause changes that reduce their lifespan. Additionally, there may also occur issues with detecting tiny objects accurately without causing any harm if these tools have complex structures.

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 , 2 The key life detection device shown includes a body 1, the bottom of which has a bottom plate 2 extending forward for placing a workpiece 12 to be tested, and one side of the body 1 is provided with an air source processor 3 capable of adjusting air pressure, The air source processor 3 is connected with a pressure regulating gauge 31, and the body 1 is connected with a plurality of miniature cylinders 4 that can be reset by its own spring force. The outer diameter of the spring and the miniature cylinder is between 4 and 10mm, which can be selected according to the specific size of the button of the workpiece to be tested. The air source processor 3 and the miniature cylinder 4 are connected through an air guide tube 10 , and the air pressure of the gas passing through the air guide tube 10 can be adjusted by adjusti

Abstract

The invention relates to a device for detecting the life of press keys, comprising a body (1), the bottom of which is provided with a base board (2) extending forwards and used for placing a tested piece (12). The device is characterized in that the body (1) is connected with at least one cylinder (4) which can push against or loosen the press keys on the tested piece (12), the cylinder (4) is connected with an external gas source by an airway tube (10), and the airway tube (10) is connected with a valve used for controlling the cylinder (4). Compared with the prior art, the device has the following advantages: the structure of the device for detecting the life of the press keys is simplified to a maximal degree by applying the pneumatic principle and effective finger-simulated key pressing action by the cylinder, thus providing guarantee for realizing high reliability, high precision and long life of the detecting device, preventing the workpiece from being interfered by electromagnet in the process of detection and solving the life detecting problem of mini press keys of dense layout effectively, and simultaneously, the press force of the cylinder can be movably adjusted according to the bearing pressure of the press keys of the tested piece.
