Embodiment Construction

[0015] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0016] see figure 1 , an anti-deflection button tester of the present invention, comprising: a platform 1, a measuring head mounting plate 3, a guide post 4 and a driving mechanism, wherein the platform 1 is used to carry and fix a product to be tested (such as a notebook computer) , the driving mechanism drives the guide post 4 to move up and down, and the guide post 4 drives the probe mounting plate 3 on which the probe 2 is installed. Preferably, a guide sleeve 5 that cooperates with the guide post 4 is provided on the platform 1 . In order to adjust the height of the platform 1 to correspond to products of various specifications, a height adjustment mechanism for driving the platform 1 to move up and down is provided under the platform 1 . Of course, the height of the probe mounting plate 3 can also be adjusted, which is more conven...

Abstract

The invention discloses an inclination-preventing key tester which comprises a platform, a test head installation plate, a guide column and a drive mechanism. The drive mechanism comprises a bottom plate, a motor, a first synchronizing wheel driven by the motor, a second synchronizing wheel driven by the first synchronizing wheel, a third synchronizing wheel, a fourth synchronizing wheel, a fifth synchronizing wheel and a sixth synchronizing wheel, wherein the third synchronizing wheel and the fourth synchronizing wheel are arranged on the two sides of the second synchronizing wheel, and the fifth synchronizing wheel and the sixth synchronizing wheel are driven by the third synchronizing wheel and the fourth synchronizing wheel. The fifth synchronizing wheel and the sixth synchronizing wheel respectively drive one eccentric shaft to rotate. The free ends of the eccentric shafts are respectively connected with one eccentric shaft connecting base. The bottoms of the eccentric shaft connecting bases are fixedly connected with a movable plate. A connecting structure fixing the guide column is formed on the movable plate. The inclination-preventing key tester has the advantages that the drive mechanism is creatively improved; the fifth synchronizing wheel and the sixth synchronizing wheel drive the two eccentric shaft connecting bases symmetrically arranged to move vertically, the phenomenon of inclination and errors, invisible to the naked eyes, of the movable plate due to long-time work can be effectively prevented, and the noise and the equipment fault are avoided.

Description

technical field [0001] The invention relates to a key tester, in particular to a deflection-proof key tester. Background technique [0002] The buttons of laptops, game controllers and other products are easy to wear and break down during use. Therefore, before the product is put on the market, the buttons will be pressed repeatedly through the button tester to simulate the actual use conditions, and then the service life of the buttons will be tested. . During the test, the button tester has been subjected to high-intensity loads. After a period of work, the button tester in the prior art will often appear tilted and biased, resulting in noise and affecting the accuracy of the test. Equipment failure. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a key tester, which can effectively prevent the device itself from being biased and tilted due to long-term work, prolong the service ...
