Description

Technical Field

[0001] This utility model relates to the field of push button switch technology, and more specifically, to a push button switch life testing device. Background Technology

[0002] A push-button switch, also known as a control button (or simply button), is a low-voltage electrical appliance that is manually operated and generally can be automatically reset. Buttons are typically used in circuits to issue start or stop commands to control the connection and disconnection of the coil current of electrical appliances such as electromagnetic starters, contactors, and relays.

[0003] Currently, the lifespan testing of push-button switches is usually conducted manually, which requires long periods of manual operation, resulting in reduced testing efficiency. Furthermore, conventional push-button switch tests are typically performed individually, leading to low actual testing efficiency and unsatisfactory practical application results.

[0004] A search revealed that Chinese patent CN221946137U discloses a button switch life testing device. On the one hand, it achieves automated testing of button switches, improving testing efficiency and work efficiency. On the other hand, it can simulate human hand operation to conduct life testing on button switches, avoiding excessive pressing of the button switches and improving the accuracy and precision of the button switch life testing.

[0005] In actual use, when testing the button switch life test device, the button switch is simply placed on the button switch holder. Since button switches come in different sizes, simply placing the button switch on the holder will cause it to wobble during testing due to unstable fixing, which will aggravate the internal wear of the button switch and thus affect the test results. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a push button switch life test device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A push-button switch life testing device includes a support frame, a base installed inside the support frame, a connecting frame fixedly connected to the inner side of the support frame, multiple guide frames fixedly connected to one side of the connecting frame, a cylinder installed at the top of the guide frame, a movable plate fixedly connected to the output end of the cylinder, a pressure head fixedly connected to one side of the movable plate, a fixed box installed on the upper surface of the base, a limit component installed inside the fixed box, and a replacement mechanism installed inside the base.

[0009] By adopting the above technical solution, the guide frame can provide guidance for the movable plate, making it easier for the movable plate to stably drive the pressure head to perform a pressing test on the button switch.

[0010] As a further description of the above technical solution: the limiting component includes a first stepper motor, which is mounted on one side of a fixed box. Multiple placement slots are provided on the upper surface of the fixed box. A first gear is fixedly connected to the output end of the first stepper motor. The first gear is rotatably connected to the interior of the fixed box. A second gear meshes with one side of the first gear. A first lead screw is fixedly connected inside the second gear. Both ends of the first lead screw are rotatably connected to the interior of the fixed box. Multiple movable rods are threaded onto the outer side of the first lead screw. A clamping rod is fixedly connected to one end of each movable rod. The clamping rod is slidably connected to the inner side of the placement slot. A guide post is slidably connected inside each movable rod. The guide post is fixedly connected to the interior of the fixed box. Three rubber posts are fixedly connected to the inner side of the placement slot. A clamping ring is fixedly connected to one end of each rubber post.

[0011] By adopting the above technical solution, the button switch can be kept stable during testing by using a stable clamping limit.

[0012] As a further description of the above technical solution: the replacement mechanism includes a second stepper motor, which is fixedly connected to one side of the base. A second lead screw is fixedly connected to the output end of the second stepper motor. The second lead screw is rotatably connected to the inside of the base. Two threaded blocks are threadedly connected to the outer side of the second lead screw. The threaded blocks are fixedly connected to the bottom end of the fixed box. Two sliding grooves are opened on the upper surface of the base. A slider is slidably connected to the inner side of the sliding groove. The slider is fixedly connected to the bottom end of the fixed box.

[0013] By adopting the above technical solution, the two fixed boxes can be replaced alternately, which helps to save operation time.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting a limiting component, compared with the existing technology, the "V" shaped cut surface on one side of the clamping rod can compress and adapt to circular button switches of different sizes, enabling simultaneous testing of button switches of different sizes. The three clamping rings limit and clamp the button switch, which can stably fix the button switch under test and reduce damage caused by excessive impact or vibration during the test.

[0016] 2. By setting up a replacement mechanism, compared with the existing technology, when testing in one fixed box, the button switches of the other part can be placed in another fixed box, and can be tested alternately, thereby saving operation time and improving the flexibility and efficiency of testing.

Multiple movable rods 14 are threadedly connected to the outer side of the first lead screw 13. A clamping rod 15 is fixedly connected to one end of each movable rod 14. The clamping rod 15 is slidably connected to the inner side of the placement slot 9. A guide post 16 is slidably connected inside the movable rod 14. The guide post 16 is fixedly connected to the inside of the fixed box 8. Three rubber posts 17 are fixedly connected to the inside of the placement groove 9. One end of each rubber post 17 is fixedly connected to a clamping ring 18. The first stepper motor 10 drives the first gear 11 to mesh and drive the second gear 12 to rotate, so that the second gear 12 can drive the first lead screw 13 to rotate.

[0028] Working principle of this utility model: This utility model designs a button switch life testing device, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation of various structures, when a life test of the push-button switch is required, the push-button switch is first placed sequentially in multiple placement slots 9 inside one of the fixed boxes 8. Then, the first stepper motor 10 is started. The first stepper motor 10 drives the first gear 11 to rotate and mesh, driving the second gear 12 to rotate. This allows the second gear 12 to drive the first lead screw 13 to rotate. The first lead screw 13 can drive the movable rod 14 to move through the thread. The clamping rod 15 can provide a guiding function for the movement of the movable rod 14, so that the movable rod 14 can stably drive the clamping rod 15 to move inside the placement slot 9. The "V" shaped cut surface on one side of the clamping rod 15 can squeeze the push-button switch and fit it against the clamping ring 18, thereby limiting the push-button switch inside the placement slot 9. Then, the second stepper motor is started. 19. The second stepper motor 19 drives the second lead screw 20 to rotate, so that the second lead screw 20 can drive two threaded blocks 21 to move through the thread, so that the two fixed boxes 8 can move. At the same time, one of the fixed boxes 8 can drive the button switch to move under the pressure head 7. Then, the cylinder 5 is started, and the cylinder 5 drives the movable plate 6 to move up and down reciprocally. The guide frame 4 can provide guidance for the movable plate 6, so that the movable plate 6 can drive the pressure head 7 to press the button switch, thereby testing the button switch. While testing the button switch, the button switch can be placed in another fixed box 8. After the button switch in one fixed box 8 has been tested, the second stepper motor 19 is started again, so that the other fixed box 8 can be moved under multiple pressure heads 7, so as to continuously test the button switch.
