Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

The switch simulation pressing test device shown in fig. 1, 2 and 3 comprises a shell 2, wherein a clamp 1 is installed on the left side of the shell 2, a tested switch 11 is installed in the clamp 1, and a switch button 12 is installed on the tested switch 11, namely, the switch button 12 of the tested switch 11 in the clamp 1 is pressed through a structure in the shell 2 to complete a test; a gear 5 which is rotatably connected with the shell 2 is arranged in the shell 2, specifically, the gear 5 rotates in a vertical plane, a first rack 3 and a second rack 6 which are meshed with the gear 5 are respectively arranged at the upper side and the lower side of the gear 5, the first rack 3 and the second rack 6 are respectively arranged in the shell 2 and are in sliding connection with the gear, namely when one of the racks slides leftwards, the rack is contacted with a switch button 12 to be pressed and enables the gear 5 meshed with the rack to rotate, so that the other rack is driven to rotate reversely, and when the rack rotates rightwards reversely, the other rack is driven to move leftwards through the gear 5 and is contacted with the switch button 12 to be pressed again, so that a test is completed; the right side of the first rack 3 is fixedly provided with the linkage rod 4, the linkage rod 4 is used for being connected with an external motion device such as an air cylinder, a screw rod and the like, so that the linkage rod 4 drives the first rack 3 to slide left and right to complete a test, the switch button 12 can be pressed twice only by one-time reciprocating motion, the test efficiency is improved, and the practicability is good.

Further, install rather than the pivot 9 of being connected of rotating in the

casing

2, 5 covers of gear are established in pivot 9 outsidely, establish its function of stabilizing the pivoted in pivot 9 outsidely through establishing gear 5 cover promptly, can rotate along with pivot 9 for guaranteeing gear 5 the outside fixed mounting of pivot 9 has an axle key 8, set up on gear 5 with axle key 8 matched with keyway, realize fixing gear 5 through setting up keyway and the cooperation of axle key 8 promptly, convenient maintenance.
