Abstract
Description
Technical Field
[0001] This utility model relates to the field of knob testing technology, and in particular to a device for testing the fatigue cycles of knob switches. Background Technology
[0002] The fatigue cycle testing equipment for rotary switches is mainly used to simulate the long-term use of rotary switches. Through an automated mechanical structure, the switch is repeatedly rotated, and its performance changes, such as conduction reliability, rotation smoothness, and structural integrity, are recorded after a set number of cycles. It can detect the switch's durability limits, verify whether it meets design standards, provide data support for product quality improvement, lifespan assessment, and reliability certification, and ensure the stability of the switch during long-term use.
[0003] Existing fatigue test equipment for rotary switches has significant shortcomings. First, the procurement cost is high, which puts a lot of financial pressure on enterprises, especially small and medium-sized enterprises. Second, the compatibility with the tested products is poor, and different specifications of knobs require specially customized tooling, making it difficult to meet diverse testing needs. Third, the equipment structure is complex, and the subsequent maintenance and operation are cumbersome, which not only consumes a lot of time, but also requires professional personnel to handle, significantly increasing maintenance costs and affecting testing efficiency.
[0004] Therefore, this application provides a fatigue test device for rotary switches to meet the requirements. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for testing the fatigue cycles of rotary switches.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rotary switch fatigue cycle testing device, including a base, and further comprising:
[0007] A first support plate is provided in the middle of the base, and an instrument is provided on the top of the first support plate. A long connecting rod is rotatably provided on the top of the instrument. A support connecting rod is rotatably provided on one side of the long connecting rod, and a short connecting rod is provided at the other end of the support connecting rod.
[0008] Furthermore, a second support plate is provided at the top of the base away from the first support plate, and a motor is provided on one side of the top of the second support plate. The bottom of the motor is rotatably connected to a short connecting rod.
[0009] The beneficial effect of adopting the above-mentioned further solution is that a second support plate is set at the top of the base away from the first support plate, and a motor is installed on one side of the top of the second support plate. The bottom of the motor is rotatably connected to the short connecting rod. When the motor runs, it drives the short connecting rod to move, and then drives the instrument to simulate the action of a rotary switch through the rotation of the support connecting rod and the long connecting rod, so as to test its fatigue number.
[0010] Furthermore, a counting sensor is provided on the side of the second support plate away from the motor.
[0011] The beneficial effect of adopting the above-mentioned further solution is that a counting sensor is designed on the side of the second support plate away from the motor. When the long connecting rod reciprocates, the counting sensor is triggered to realize the automatic counting of fatigue times.
[0012] Furthermore, a counter is provided on the side of the second support plate away from the counting sensor.
[0013] The beneficial effect of adopting the above-mentioned further solution is that a counter is set on the side of the second support plate away from the counting sensor, and the counting sensor transmits the detection signal to the counter to display the fatigue number of the rotary switch in real time.
[0014] Furthermore, the counting sensor is positioned on the top of the second support plate near the long connecting rod.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the counting sensor is located on the top of the second support plate near the long connecting rod, which can accurately capture the reciprocating motion of the long connecting rod and transmit the signal to the counter to ensure accurate counting.
[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0017] A first support plate is set in the middle of the base, and an instrument is installed on the top of the first support plate. A long connecting rod is rotatably connected to the top of the instrument. A support connecting rod is rotatably connected to one side of the long connecting rod, and a short connecting rod is set at the other end of the support connecting rod. This allows for fatigue testing of the rotary switch, simulating the actual use of the rotary switch, thereby detecting its performance and lifespan under multiple operations.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a fatigue test device for rotary switches, including a base 1, and further comprising:
[0026] A first support plate 9 is provided in the middle of the base 1. An instrument 2 is mounted on the top of the first support plate 9. A long connecting rod 3 is rotatably connected to the top of the instrument 2. A support connecting rod 8 is rotatably connected to one side of the long connecting rod 3. A short connecting rod 7 is provided at the other end of the support connecting rod 8. The first support plate 9 is located in the middle of the base 1. The instrument 2 is mounted on the top of the first support plate 9. The long connecting rod 3 is rotatably connected to one side of the long connecting rod 3. A short connecting rod 7 is provided at the other end of the support connecting rod 8. This configuration allows for fatigue testing of the rotary switch, simulating the actual use of the rotary switch, thereby detecting its performance and lifespan under repeated operation.
[0027] Furthermore, such as Figures 1-4 As shown: A second support plate 10 is provided on the top of the base 1 away from the first support plate 9. A motor 6 is provided on one side of the top of the second support plate 10. The bottom of the motor 6 is rotatably connected to the short connecting rod 7. When the motor 6 is running, it drives the short connecting rod 7 to move. In turn, through the rotation of the support connecting rod 8 and the long connecting rod 3, the instrument 2 is driven to simulate the action of a rotary switch to test its fatigue cycle.
[0028] The above solutions still have the problem of device counting, such as... Figures 1-4 As shown: In this scheme, a counting sensor 5 is set on the side of the second support plate 10 away from the motor 6. The counting sensor 5 is designed on the side of the second support plate 10 away from the motor 6. When the long connecting rod 3 reciprocates, it triggers the counting sensor 5 to realize the automatic counting of fatigue times.
[0029] Working principle: such as Figures 1-4As shown, the base 1 serves as the basic load-bearing component, with a first support plate 9 in its middle to stably support the instrument 2 on top. The instrument 2 simulates the rotary switch to be tested. The top of the instrument 2 is rotatably connected to a long connecting rod 3, one side of which is rotatably connected to a support connecting rod 8. The other end of the support connecting rod 8 is connected to a short connecting rod 7, forming a transmission mechanism. The base 1 has a second support plate 10 located away from the first support plate 9, with a motor 6 mounted on one side of its top. The bottom of the motor 6 is rotatably connected to the short connecting rod 7. The operation of the motor 6 drives the short connecting rod 7 to move, which, through the support connecting rod 8 and the long connecting rod 3, drives the knob of the instrument 2 to reciprocate, simulating actual use. A counting sensor 5 is designed on the side of the second support plate 10 away from the motor 6, and it is located near the top of the long connecting rod 3. This sensor can accurately capture the reciprocating motion of the long connecting rod 3 and generate a signal. A counter 4 is designed on the side of the second support plate 10 away from the counting sensor 5, which receives the sensor signal and displays the number of times in real time, realizing accurate testing and recording of the fatigue count of the rotary switch.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
