A simulated foot-stepping mechanism and an intelligent control panel are mounted on the support. An inspection platform is positioned between the inner walls of both sides of the support. Four foot switches are mounted on the top of the inspection platform via a limiting component. This utility model utilizes the limiting component on the inspection platform to clamp multiple foot switches simultaneously, and only one bolt is needed to fix multiple foot switches, thus facilitating subsequent disassembly and assembly.

Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a testing device for foot switches. Background Technology

[0002] Foot switches are key control components in industrial equipment, medical instruments, and construction machinery. Their reliability directly affects the safety and efficiency of equipment operation. Since foot switches are mainly used by stepping, their internal components will fail after prolonged use, resulting in foot switch failure.

[0003] In practical use, foot switches are often used in complex environments such as vibration and bumps. However, previous tests only focused on static pedaling performance and could not simulate the reliability of foot switches under real working conditions, which is inconvenient to use. Therefore, we propose a testing device for foot switches to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a testing device for foot switches, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

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

[0008] A testing device for foot switches includes a workbench with a bracket fixed to its top. A simulated stepping mechanism and an intelligent control panel are mounted on the bracket. A testing platform is disposed between the inner walls of both sides of the bracket. Four foot switch components are mounted on the top of the testing platform via limiting components. A vibration mechanism for causing the testing platform to vibrate is mounted on the top of the workbench. The simulated stepping mechanism includes a cylinder fixed to the top of the bracket. The protruding end of the cylinder slides through the bracket and extends below it, where a movable plate is fixed. Four pressure rods are fixed to the bottom of the movable plate.

[0009] Furthermore, the limiting component includes a limiting block fixed to the top of the inspection table, and a limiting frame adapted to the foot switch is snapped onto the top of the limiting block. The limiting frame is threadedly connected to the limiting block by bolts. Four positioning frames adapted to the foot switch are fixed to the top of the inspection table, and the foot switch is limited and fixed between the limiting frame and the positioning frame.

[0010] Furthermore, the vibration mechanism includes a cylinder body two fixed on the workbench, a horizontal plate fixed to the top end of the cylinder body two, vertical striking posts fixed to the four corners of the top of the horizontal plate, two guide seats fixed to the top of the workbench, and a transverse striking rod slidingly through the side wall of each of the two guide seats.

[0023] 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.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of this utility model discloses a testing device for a foot switch, including a workbench 1. Four omnidirectional casters 9 are fixed to the bottom of the workbench 1. These casters facilitate short-distance movement of the testing device by the operator and have a self-locking function to limit displacement during use. Furthermore, four mechanical support feet are installed on the base plate of the workbench 1, located on one side of each caster 9, further enhancing the stability of the testing device after placement. The four mechanical support legs are not shown in the diagram. A bracket 2 is fixed to the top of the workbench 1. A simulated foot-stepping mechanism 3 and an intelligent control panel 4 are mounted on the bracket 2. The intelligent control panel 4 has counting and timing functions, allowing control over the number and duration of foot-operated switches 7 and the duration of vibration testing. An inspection platform 5 is located between the inner walls of both sides of the bracket 2. Four foot-operated switches 7 are mounted on the top of the inspection platform 5 via limiting components 6. A vibration mechanism 8 is mounted on the top of the workbench 1 to cause the inspection platform 5 to vibrate. The simulated foot-stepping mechanism 3 includes a cylinder 31 fixed to the top of the bracket 2. The cylinder body 31 extends slidably through the bracket 2 to its lower part and is fixed with a movable plate 32. Four pressure rods 33 are fixed at the bottom of the movable plate 32. Guide rods 34 slide inside the two through holes at the top of the bracket 2. The bottom ends of the guide rods 34 are fixedly connected to the top of the movable plate 32, which can provide auxiliary support and guidance for the movable plate 32, so as to make it more stable during the up and down movement. In the process of using this foot switch inspection device, the four foot switch components 7 can be installed and fixed on the top of the inspection table 5 at one time through the limit component 6, ensuring that the foot switch components 7 will not loosen or shift during the inspection process. When it is necessary to simulate repeated stepping tests on the foot switch component 7, the top end of the cylinder 31 can reciprocate to move the moving plate 32 back and forth. The reciprocating movement of the moving plate 32 can drive the pressure rod 33 to repeatedly switch the foot switch component 7 on and off. The operator can set the test parameters, such as the force, frequency, and number of steps, through the intelligent control panel 4 on the bracket 2. When it is necessary to simulate the foot switch component 7 under vibration, the vibration mechanism 8 can be activated to drive the test table 5 to vibrate horizontally or vertically, so as to simulate different vibration directions to test the foot switch component 7.When it is necessary to simulate repeated stepping of the foot switch 7 under vibration, it is only necessary to simultaneously activate the simulated stepping mechanism 3 and the vibration mechanism 8. This simulates the vibration and bumpy environment of the foot switch 7 during equipment operation. Throughout the inspection process, the intelligent control panel 4 monitors the operating status of the simulated stepping mechanism 3 and the vibration mechanism 8 in real time and records relevant data. After the inspection is completed, the operator shuts down the device, releases the limit component 6, and removes the inspected foot switch 7, thus completing one inspection. Furthermore, since the intelligent control panel 4 and cylinder 31 are existing technologies, their models and electrical connections can be determined by those skilled in the art through research, and therefore will not be elaborated further here.

[0026] like Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, the limiting component 6 includes a limiting block 61 fixed to the top of the inspection table 5. The top of the limiting block 61 is snapped with a limiting frame 62 adapted to the foot switch component 7. The limiting frame 62 is threadedly connected to the limiting block 61 by bolts 64. The top of the inspection table 5 is fixed with four positioning frames 63 adapted to the foot switch component 7. The foot switch component 7 is limited and fixed between the limiting frame 62 and the positioning frame 63. In use, the foot switch component 7 is inserted into the inside of the positioning frame 63, and then the limiting frame 62 and the limiting block 61 are snapped together and locked with bolts 64. At this time, the foot switch component 7 will be limited between the limiting frame 62 and the positioning frame 63. When disassembling and assembling the foot switch component 7, only one bolt 64 needs to be operated.

[0027] like Figure 2 and Figure 4As shown, in some embodiments, the vibration mechanism 8 includes a cylinder 81 fixed to the workbench 1. A horizontal plate 82 is fixed to the top end of the cylinder 81. Four guide tubes 88 are fixed to the top of the workbench 1. Four guide posts 89, which are adapted to the guide tubes 88, are fixed to the bottom of the horizontal plate 82, which can guide and support the horizontal plate 82 to enhance its stability during vertical movement. Vertical striking posts 83 are fixed to the four corners of the top of the horizontal plate 82. Two guide seats 84 are fixed to the top of the workbench 1. Horizontal striking rods 85 slide through the side walls. One end of each horizontal striking rod 85 is rotatably connected to a connecting rod 86 via a pin. The other end of each connecting rod 86 is rotatably connected to the bottom of the horizontal plate 82 via a pin. Four springs 87 are fixed to the top of the workbench 1. The tops of each spring 87 are fixedly connected to the inspection table 5. In use, when vertical vibration of the inspection table 5 is required, after the cylinder 2 81 is started, its top end can drive the horizontal plate 82 to move up and down. The up and down movement of the horizontal plate 82 will drive the vertical striking columns 83 fixed at the four corners of its top to move up and down. When the vertical striking column 83 moves upward, it generates an upward striking force on the bottom of the inspection table 5. When the horizontal plate 82 moves the vertical striking column 83 downward, the inspection table 5 moves downward under its own weight and the elastic restoring action of the four springs 87 at the top, thus generating continuous vertical vibration in the inspection table 5. When lateral vibration of the inspection table 5 is required, by controlling the extension and retraction distance of the top end of the cylinder 81, the extension and retraction of the top end drives the horizontal plate 82 to move up and down without causing the vertical striking column 83 to impact the bottom of the inspection table 5. When the inspection table 5 comes into contact, the horizontal plate 82 moves back and forth, and under the action of the connecting rod 86, it can drive the horizontal striking rod 85 to move back and forth. Under the limiting action of the guide seat 84, the horizontal striking rod 85 can make horizontal reciprocating motion, so that the horizontal striking rod 85 can reciprocate to strike the inspection table 5, so that it can continuously vibrate laterally. When it is necessary to vibrate the inspection table 5 in multiple directions, the horizontal plate 82 moves up and down, and at the same time drives the vertical striking column 83 and the horizontal striking rod 85 to alternately strike the inspection table 5 in the vertical and horizontal directions. With the elastic action of the spring 87, the inspection table 5 can be vibrated in both vertical and horizontal directions. The pin mentioned above is fixed inside the connecting hole of the connecting rod 86. The pin at the upper end of the connecting rod 86 is rotatably connected to the bottom of the horizontal plate 82 through the bearing, and the pin at the lower end is rotatably connected to the horizontal striking rod 85 through the bearing. Both ends of the pin are limited to prevent them from falling off.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
