Description
Technical Field
[0001] This application relates to the field of auxiliary switch technology, specifically to an auxiliary switch switching stroke adjustment device. Background Technology
[0002] Existing auxiliary switching devices are widely used in the field of mechanical control, especially in circuit switching and automation equipment, where they play a key role in executing actions.
[0003] Traditional adjustment methods often rely on fixed structures or single adjustment components, making it difficult to flexibly compensate for errors and limiting adjustment accuracy. Especially under complex operating conditions, accumulated assembly errors may lead to misalignment between the cam and the auxiliary switch, resulting in switching delays or failures. To address these issues, an auxiliary switch switching stroke adjustment device is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an auxiliary switch switching stroke adjustment device with a simple structure, flexible adjustment, and error compensation capability, which can improve switching accuracy and long-term reliability while reducing maintenance costs.
[0005] To achieve the above objectives, this application provides the following technical solution: an auxiliary switch switching stroke adjustment device, comprising an auxiliary switch body and a stroke adjustment assembly, wherein the stroke adjustment assembly includes a connecting rod, one end of the connecting rod having an adjustment groove, an adjustment bolt being rotatably connected to the inner wall of the adjustment groove, a slider being threadedly connected to the outer surface of the adjustment bolt, a first drive shaft being mounted on the top of the slider, a cam being mounted on the outer surface of the first drive shaft, a second drive shaft being mounted on one side of the cam, an adjustment plate being mounted on the outer surface of the slider, a U-shaped notch being opened on one side of the adjustment plate, a positioning screw hole being opened on the inner wall of the connecting rod, and a positioning bolt being threadedly connected to the inner wall of the positioning screw hole.
[0006] The above scheme achieves more precise stroke adjustment through the U-shaped notch on the adjustment plate and the cooperation of the adjustment bolt and slider, effectively compensating for manufacturing and assembly errors. By utilizing the synergistic effect of the cam and the adjustment plate, it dynamically adapts to different working conditions, ensuring accurate triggering of the auxiliary switch body. The modular adjustment unit, composed of adjustment bolts, adjustment plate and positioning bolts, only requires tightening or loosening the positioning bolts to complete the calibration. The structural design of the stroke adjustment component can be adapted to various specifications of auxiliary switch bodies, reducing modification costs and improving versatility. These innovative structures together achieve the technical advantages of high precision, high reliability and easy maintenance.
[0007] Furthermore, the slider is slidably sleeved on the inner wall of the adjustment groove.
[0008] By defining the relationship between the slider and the adjustment groove, the slider can move axially along the adjustment groove when the adjustment bolt rotates, thereby driving the first transmission shaft and the cam to move synchronously, thus achieving precise control of the trigger stroke of the auxiliary switch body.
[0009] Furthermore, the second drive shaft is located above the first drive shaft, and the connecting rod contacts the auxiliary switch body via a cam.
[0010] The above scheme defines the relationship between the first and second drive shafts, forming a layered transmission structure and optimizing the spatial layout. At the same time, the connecting rod contacts the auxiliary switch body through the cam, which can ensure accurate power transmission and achieve reliable switch triggering action.
[0011] Furthermore, the positioning bolt is located inside the U-shaped notch, and the positioning bolt is adapted to the adjusting plate.
[0012] The above solution enables precise positioning of the adjusting plate through threaded locking, ensuring structural stability after stroke adjustment, preventing displacement deviation during operation, and guaranteeing the accuracy of auxiliary switch triggering.
[0013] Furthermore, the connecting rod has reinforcing structures on both its upper and lower sides.
[0014] The above solution can significantly improve the bending strength of the connecting rod while ensuring a lightweight structure, preventing deformation during transmission and ensuring the stability of stroke adjustment and transmission accuracy.
[0015] Furthermore, an installation assembly is installed inside the auxiliary switch body, and an external assembly is installed on the other side of the connecting rod.
[0016] Through the above scheme, the internal mounting components of the auxiliary switch body provide stable support and electrical connection, while the external components on the other side of the connecting rod are used to connect the external drive mechanism to realize the linkage control of power input and the overall device.
[0017] Furthermore, the adjusting bolt is provided with an anti-loosening washer on its exterior, and a serrated pattern is provided between the anti-loosening washer and the contact surface of the slider.
[0018] The above solution, by adding anti-loosening shims and serrated texture design, ensures that the position is fixed after adjustment and avoids displacement due to vibration or external force.
[0019] Furthermore, the cam is connected to the first drive shaft via a keyway, and an elastic buffer pad is embedded in the keyway.
[0020] The above solution limits the connection between the cam and the first drive shaft and introduces an elastic buffer pad to improve transmission stability and reduce the risk of wear.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This auxiliary switch switching stroke adjustment device achieves more precise stroke adjustment through the U-shaped notch on the adjustment plate and the cooperation of the adjustment bolt and slider, effectively compensating for manufacturing and assembly errors. Utilizing the synergistic effect of the cam and adjustment plate, it dynamically adapts to different working conditions, ensuring accurate triggering of the auxiliary switch body.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0031] Please see Figure 1 , Figure 4 and Figure 5 An auxiliary switch switching stroke adjustment device in this embodiment includes an auxiliary switch body 1 and a stroke adjustment component 2. The stroke adjustment component 2 includes a connecting rod 201. One end of the connecting rod 201 is provided with an adjustment groove 202. An adjustment bolt 203 is rotatably connected to the inner wall of the adjustment groove 202. A slider 204 is threadedly connected to the outer surface of the adjustment bolt 203. An anti-loosening washer is provided on the outside of the adjustment bolt 203. A serrated pattern is provided between the contact surface of the anti-loosening washer and the slider 204. By adding the anti-loosening washer and the serrated pattern design, the position is fixed after adjustment, avoiding displacement due to vibration or external force.
[0032] Please see Figure 2 , Figure 4 and Figure 5 A first drive shaft 205 is mounted on the top of the slider 204. A cam 207 is mounted on the outer surface of the first drive shaft 205. The cam 207 and the first drive shaft 205 are connected by a keyway, and an elastic buffer pad is embedded in the keyway. This limits the connection between the cam 207 and the first drive shaft 205 and introduces the elastic buffer pad to improve transmission stability and reduce the risk of wear. A second drive shaft 206 is mounted on one side of the cam 207. The second drive shaft 206 is located above the first drive shaft 205 and limits the relationship between the first drive shaft 205 and the second drive shaft 206, forming a layered transmission structure and optimizing the spatial layout. The connecting rod 201 contacts the auxiliary switch body 1 through the cam 207. The contact between the connecting rod 201 and the auxiliary switch body 1 through the cam 207 can ensure accurate power transmission and realize reliable switch triggering action.
[0033] Please see Figure 3 , Figure 4 and Figure 5 The slider 204 is slidably sleeved on the inner wall of the adjusting groove 202. By limiting the relationship between the slider 204 and the adjusting groove 202, when the adjusting bolt 203 rotates, the slider 204 can move axially along the adjusting groove 202, thereby driving the first transmission shaft 205 and the cam 207 to move synchronously, realizing precise control of the trigger stroke of the auxiliary switch body 1. An adjusting plate 208 is installed on the outer surface of the slider 204. A U-shaped notch 209 is opened on one side of the adjusting plate 208. A positioning screw hole 210 is opened on the inner wall of the connecting rod 201. A positioning bolt 211 is threadedly connected to the inner wall of the positioning screw hole 210. The positioning bolt 211 is located inside the U-shaped notch 209 and is adapted to the adjusting plate 208. The adjusting plate 208 can be precisely positioned by thread locking, ensuring the structural stability after stroke adjustment, preventing displacement deviation during operation, and ensuring the accuracy of triggering the auxiliary switch body 1.
[0034] Please see Figure 1 , Figure 2 and Figure 3 The upper and lower sides of the connecting rod 201 are provided with reinforcing structures 212, which can significantly improve the bending strength of the connecting rod 201 while ensuring the lightweight structure, prevent deformation during transmission, and ensure the stability and transmission accuracy of the stroke adjustment. The auxiliary switch body 1 is equipped with an installation component 3, and the other side of the connecting rod 201 is equipped with an external component 4. The function of the installation component 3 inside the auxiliary switch body 1 is to provide stable support and electrical connection, and the external component 4 on the other side of the connecting rod 201 is used to connect to an external drive mechanism to realize the linkage control of power input and the overall device.
[0035] In this embodiment, an auxiliary switch switching stroke adjustment device achieves more precise stroke adjustment through the cooperation of the U-shaped notch 209 on the adjustment plate 208 with the adjustment bolt 203 and the slider 204, effectively compensating for manufacturing and assembly errors. Utilizing the synergistic effect of the cam 207 and the adjustment plate 208, it dynamically adapts to different working conditions, ensuring accurate triggering of the auxiliary switch body 1. The modular adjustment unit, composed of the adjustment bolt 203, adjustment plate 208, and positioning bolt 211, only requires tightening or loosening the positioning bolt 211 to complete calibration. The structural design of the stroke adjustment component 2 can adapt to various specifications of auxiliary switch bodies 1, reducing modification costs and improving versatility. The reinforcing structure 212 of the connecting rod 201 maintains lightweight while increasing rigidity. These innovative structures collectively achieve the technical advantages of high precision, high reliability, and easy maintenance.
[0036] The working principle of the above embodiment is as follows: When the trigger stroke needs to be adjusted, first loosen the positioning bolt 211 so that the adjusting plate 208 is unlocked from the first drive shaft 205 and the second drive shaft 206 on the connecting rod 201 through its U-shaped notch 209. Then rotate the adjusting bolt 203 to drive the slider 204, which is threaded to it, to slide along the inner wall of the adjusting groove 202 of the connecting rod 201, thereby driving the adjusting plate 208 to move synchronously, thereby changing the initial position of the first drive shaft 205 and the cam 207, and realizing the stroke fine adjustment. After the adjustment is completed, tighten the positioning bolt 211 to fix the adjusting plate 208 on the connecting rod 201. At this time, the cooperation relationship between the U-shaped notch 209 and the first drive shaft 205 and the second drive shaft 206 is determined, forming In a rigid transmission link, when an external driving force is applied to the connecting rod 201 through the external component 4, the connecting rod 201 drives the cam 207 to rotate. Its contour precisely controls the trigger stroke of the auxiliary switch body 1. During this process, the U-shaped notch 209 of the adjusting plate 208 can dynamically compensate for the accumulated errors caused by manufacturing or assembly, while the reinforcing structure 212 can ensure that the connecting rod 201 does not deform when under force, maintaining transmission accuracy. At the same time, the keyway connection between the cam 207 and the first transmission shaft 205 has an embedded elastic buffer pad to absorb transmission impact. Finally, through the stable support and electrical connection of the mounting component 3, the entire process of "adjustment-locking-transmission-compensation" is closed-loop controlled, ensuring high precision and high reliability of the auxiliary switch switching action.
