Description

Technical Field

[0001] This utility model relates to the field of circuit switch testing technology, and in particular to a click-resistant testing fixture for circuit switches. Background Technology

[0002] Circuit switch click resistance testing equipment is generally used to continuously trigger the circuit switch during circuit switch testing to test the click resistance test effect. It is applied to circuit switch testing applications.

[0003] In the prior art, Chinese patent application number 202220092791.5 discloses a circuit switch click resistance testing device, including a fixed base plate, a support stand mounted on the upper end of the fixed base plate, a triggering mechanism mounted on the top of the support stand, and a clamping mechanism mounted on the upper end of the fixed base plate in front of the support stand. The triggering mechanism includes a rotary motor, a motor shaft, a rotary connecting plate, an eccentric bracket, an eccentric ring, a lifting connecting sleeve, a lifting rod, a trigger head, and a positioning frame, with the positioning frame mounted at the front end of the support stand. This utility model's circuit switch click resistance testing device achieves rapid click triggering through an eccentric rotation and lifting structure. It has a simple structure and is more durable for click resistance testing. During circuit switch testing, the movement of the switch clamp allows for continuous circuit switch replacement and adjustment of the testing position, making it more convenient for testing different circuit switches.

[0004] However, the above technical solutions have drawbacks. Due to the different thicknesses of different circuit switches, the switch pressing strokes are also different, making it impossible to adjust the distance between the trigger head and the switch, resulting in poor applicability. At the same time, it is impossible to achieve click counting, making it difficult to accurately judge the detection data of the circuit switch, thus reducing its practicality. Therefore, this application proposes a click-resistant detection fixture for circuit switches to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to adjust the distance between the trigger head and the switch due to the different thicknesses and varying pressing strokes of different circuit switches, resulting in poor applicability, the inability to count clicks, and the difficulty in accurately judging the detection data of the circuit switch. Therefore, this invention proposes a click-resistant testing fixture for circuit switches.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A click resistance testing fixture for circuit switches includes a testing table, and the click resistance testing fixture further includes:

[0008] A fixing plate, the bottom end of which is fixedly installed on the top of the testing table;

[0009] The click component includes: a motor, a cam, a bearing, a support rod, a slip ring, a click rod, a bracket, a guide wheel, and a spring. The motor is fixedly installed on the left side of the fixed plate, and the output shaft of the motor passes through the fixed plate and is fixedly connected to the cam. The bearing is fixedly sleeved on the output shaft of the motor, and the bottom of the bearing is fixedly installed on the top of the support rod. The left end of the support rod is fixedly installed on the right side of the fixed plate. The left end of the slip ring is fixedly installed on the support rod and is slidably sleeved on the click rod. The bottom of the bracket is fixedly installed on the top of the click rod. The guide wheel is rotatably connected inside the bracket and is rotatably connected to the cam. The spring is sleeved on the click rod, and the top of the spring is fixedly installed on the bottom of the bracket. The bottom end of the spring is fixedly installed on the top of the slip ring.

[0010] A placement plate is set above the testing table. Multiple first electric push rods are fixedly installed on the top of the placement plate. Movable clamps are fixedly installed on the output shafts of the multiple first electric push rods. Multiple fixed clamps are fixedly installed on the top of the placement plate. Multiple switch bodies are placed on the top of the placement plate. The switch bodies cooperate with the corresponding fixed clamps and movable clamps respectively.

[0011] An adjustment component is provided, which is mounted on the testing platform and engages with the bottom of the placement plate.

[0012] In a preferred embodiment of this utility model, an infrared transmitter is fixedly installed on the left side of the click rod, and an infrared receiver is fixedly installed on the right side of the fixing plate, with the infrared transmitter and the infrared receiver working together.

[0013] As a preferred embodiment of this utility model, a counting display is fixedly installed on the right side of the fixing plate, and the counting display is respectively matched with the infrared transmitter and the infrared receiver.

[0014] In a preferred embodiment of this utility model, the adjustment assembly includes a rotating seat and a second electric push rod. The bottom of the rotating seat is placed on the top of the testing platform, and the bottom of the placement plate is rotatably connected to the top of the rotating seat. The second electric push rod is fixedly installed on the bottom of the testing platform, and the output shaft of the second electric push rod passes through the testing platform and is fixedly installed on the bottom of the rotating seat.

[0015] In a preferred embodiment of this utility model, a drive motor is fixedly installed inside the rotating seat, and the output shaft of the drive motor is fixedly installed at the bottom of the placement plate.

[0016] As a preferred embodiment of this utility model, a plurality of stabilizing rods are fixedly installed at the bottom of the rotating seat, and the bottom ends of the plurality of stabilizing rods all penetrate the testing platform.

[0017] Beneficial effects:

[0018] 1. By placing multiple switch bodies sequentially on top of the placement plate, the first electric push rod can be activated to move the moving clamp. The cooperation between the moving clamp and the fixed clamp can stably clamp and fix the multiple switch bodies. In addition, the motor can be activated to drive the cam to rotate. When the cam rotates, the eccentric rotation characteristic of the cam and the rolling cooperation between the guide wheel and the elastic reset characteristic of the spring can drive the bracket and the click rod to move up and down reciprocally. This allows the bottom end of the click rod to reciprocate the click operation on the corresponding switch body, thereby realizing the click resistance test of the switch body.

[0019] 2. By moving the lever up and down, the infrared transmitter can be moved up and down. When the infrared transmitter descends to the bottom, it corresponds to the height of the infrared receiver. At this time, the signal emitted by the infrared transmitter can be received and transmitted by the infrared receiver to record the number of clicks. A counter display can be set up to display the number of clicks for easy viewing by personnel.

[0020] 3. By activating the first electric push rod, the rotating seat and the placement plate can be adjusted in height, thereby enabling the height adjustment of the switch body. In this way, the distance between the bottom of the switch body and the click rod can be adjusted appropriately according to the thickness of the switch body. This allows for click resistance testing of switch bodies of different models and sizes, making it highly applicable.

[0021] This invention achieves click resistance testing of circuit switches of different thicknesses through a simple structure, enables adjustment of the distance between the trigger head and the switch, and realizes click counting. It can accurately judge the test data of the circuit switch and has strong applicability and practicality. Attached Figure Description
