Description

Technical Field

[0001] The present invention relates to the technical field of automation mechanisms, and in particular to a thrust testing mechanism.

Background Art

[0002] As Figures 1 to 2 shown, the product 10 is provided with a first button 20 and a second button 30. Thus, it is necessary to test the two buttons 40 of the product 10 respectively to determine whether the thrust value is greater than the set standard value. The current testing method is to manually hold a thrust gauge to test the thrust of the first button 20 and the second button 30 respectively, and then judge whether it is qualified according to the set standard thrust value. However, its testing speed is slow and it cannot be used for rapid production line operation. Moreover, when manually performing the thrust test, due to inertia, the test value is likely to be inaccurate, which affects the test result of the button 40 of the product 10.

[0003] In view of this, it is necessary to provide a thrust testing mechanism to solve the above problems.

One side of the fixed plate 120 is fixed with a handle 123 through a fixing member 110, which is used for manually lifting the fixed plate 120 along the guide post 104 through the handle 123, and then the product 10 can be placed on the jig 100. The other side of the fixed plate 120 is fixed with a guide rail 124 through a fixing member 110, and a slider 125 is movably arranged on the guide rail 124. The fixed plate 120 is fixed with a limit block 126 through a fixing member 110, and the limit block 126 is used to limit the displacement when manually pushing the thrust block 130;

One end of the thrust block 130 is connected with a sleeve 131 through an elastic member 132. The sleeve 131 can push the button 40 of the product 10 under the action of the elastic member 132. A limiting rod 134 is fixed on one side of the thrust block 130.
