Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a switch operating mechanism. Background Technology

[0002] In the control system of electrical equipment, the switch operating mechanism, as the core execution unit for realizing circuit switching, directly affects the operational safety and user experience of the electrical system due to its ease of operation, stability, and anti-interference capability. Currently, while mainstream switch operating mechanisms on the market have achieved certain breakthroughs in size control and operational reliability through optimized transmission structures (such as simplified gear transmission and the use of eccentric hinges), they still have significant shortcomings in the crucial function of locking the operating state. In particular, the lack of a mature and reliable self-locking press structure design leads to many problems that urgently need to be solved in practical applications.

[0003] Utility model patent CN215680586U discloses a drive system for a switch operating mechanism, which includes a bracket. The key feature is that a sliding plate can slide left and right on the bracket, and the sliding plate is connected to a drive control system. The entire drive system for the switch operating mechanism has the advantages of modular component layout, compact structure, convenient and quick installation and maintenance, easy operation, and high reliability.

[0004] However, existing switch operating mechanisms mostly rely on continuous external force or external locking components (such as knob locks and snap-on covers) to maintain the on / off state, lacking an integrated self-locking mechanism based on pressing action. In daily use scenarios, this design is prone to accidental switching due to accidental touch, vibration, or environmental interference. For example, switches in industrial equipment control cabinets may be triggered by vibrations during equipment operation, and switches in household distribution boxes may cause sudden power outages due to accidental touches. This not only affects the normal operation of equipment but may also lead to data loss, production interruptions, or even electrical safety accidents, making it difficult to meet the needs of scenarios with high operational safety requirements (such as medical equipment, precision instruments, and emergency power supply systems). Utility Model Content

[0005] This invention provides a switch operating mechanism to solve the problem of self-locking when pressed in existing switches.

[0006] This utility model provides the following technical solution: a switch operating mechanism, including a mounting housing, and further comprising:

[0007] A support column is installed inside the mounting housing. A self-locking mechanism is sleeved on the surface of the support column. The self-locking mechanism includes a support spring, a self-locking block, a limit slide rail, and a self-locking rod.

[0008] A positioning post is provided on the lower surface of the mounting housing, and a disassembly and assembly mechanism is inserted into the surface of the positioning post. The disassembly and assembly mechanism includes a positioning ring, a pin, a buffer spring, and a handle.

[0009] In a preferred embodiment of this utility model, the support spring is sleeved on the surface of the support column, and a self-locking block is fixedly connected to the top of the support spring.

[0010] As a preferred embodiment of this utility model, a limiting slide rail is provided on the surface of the self-locking block, and a self-locking rod is slidably connected to the back of the limiting slide rail.

[0011] In a preferred embodiment of this invention, the positioning ring is inserted into the surface of the positioning post, and a pin is inserted into the interior of the positioning ring.

[0012] As a preferred embodiment of this utility model, a buffer spring is sleeved on the surface of the pin, and a handle is fixedly connected to one side of the pin.

[0013] As a preferred embodiment of this utility model, one side of the buffer spring is fixedly connected to the surface of the positioning ring, and the other side of the buffer spring is fixedly connected to the surface of the handle.

[0014] As a preferred embodiment of this utility model, the self-locking block has sliders on both sides, the sliders are slidably connected to the grooves opened in the inner wall of the mounting housing, and the top of the self-locking block is fixedly connected to two connecting rods, the top of the connecting rods is equipped with a connecting plate, and the surface of the connecting plate is provided with a pressing button.

[0015] As a preferred embodiment of this utility model, threaded holes are provided on both sides of the surface of the mounting housing, and positioning bolts are threaded into the internal threads of the threaded holes.

[0016] Compared with the prior art, the present invention provides a switch operating mechanism, which has the following beneficial effects:

[0017] 1. This switch operating mechanism, through the setting of a self-locking mechanism, when in use, pressing the top button causes the bottom self-locking block to slide inside the mounting housing via a connecting rod. The self-locking block compresses the bottom support spring and causes the self-locking rod in the surface limit slide rail to slide inside. When the self-locking rod slides to the top of the limit slide rail, it is locked in its groove. If you continue to press down, the self-locking rod moves again until it moves out of the groove and returns to the starting position at the bottom, thus achieving the self-locking effect. The structure is simple and easy to operate.

[0018] 2. The switch operating mechanism, through its disassembly and assembly mechanism, addresses the issue of wear and tear on the self-locking rod during long-term use, necessitating periodic replacement and maintenance. A positioning ring is fitted onto the bottom positioning post surface to limit the self-locking rod's movement. Pins are located on both sides of the positioning ring, and these pins are matched with limiting holes on the positioning post surface. Pulling the handle on one side of the pin causes it to move due to the elastic potential energy provided by the buffer spring, until the positioning ring reaches the appropriate position. Releasing the handle then inserts the pin into the limiting hole on the positioning post surface, thus achieving quick disassembly and assembly of the self-locking rod without the need for bolts, improving the efficiency of the operator.

[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] Please see Figure 1 - Figure 4 This utility model discloses a switch operating mechanism, including a mounting housing 1, and further comprising:

[0026] A support column 2 is installed inside the mounting housing 1. A self-locking mechanism 3 is sleeved on the surface of the support column 2. The self-locking mechanism 3 includes a support spring 301, a self-locking block 302, a limit slide rail 303, and a self-locking rod 304.

[0027] A positioning post 4 is provided on the lower surface of the mounting housing 1. A disassembly and assembly mechanism 5 is inserted into the surface of the positioning post 4. The disassembly and assembly mechanism 5 includes a positioning ring 501, a pin 502, a buffer spring 503, and a handle 504.

[0028] Specifically, the support spring 301 is sleeved on the surface of the support column 2, and a self-locking block 302 is fixedly connected to the top of the support spring 301.

[0029] In this embodiment, when in use, pressing the top button 9 causes the bottom self-locking block 302 to slide inside the mounting housing 1 via the connecting rod 7. The self-locking block 302 compresses the bottom support spring 301 and causes the self-locking rod 304 in the surface limiting slide rail 303 to slide inside. When the self-locking rod 304 slides to the top of the limiting slide rail 303, it will be locked in its groove. If you continue to press down, the self-locking rod 304 will move again until it moves out of the groove and returns to the starting position at the bottom.

[0030] Specifically, a limiting slide rail 303 is provided on the surface of the self-locking block 302, and a self-locking rod 304 is slidably connected to the back of the limiting slide rail 303.

[0031] In this embodiment, when in use, pressing the top button 9 causes the bottom self-locking block 302 to slide inside the mounting housing 1 via the connecting rod 7. The self-locking block 302 compresses the bottom support spring 301 and causes the self-locking rod 304 in the surface limiting slide rail 303 to slide inside. When the self-locking rod 304 slides to the top of the limiting slide rail 303, it will be locked in its groove. If you continue to press down, the self-locking rod 304 will move again until it moves out of the groove and returns to the starting position at the bottom.

[0032] Specifically, the positioning ring 501 is inserted into the surface of the positioning post 4, and the positioning ring 501 has a pin 502 inserted inside.

[0033] In this implementation scheme, since the self-locking rod 304 will wear out during long-term use and needs to be replaced and maintained regularly, a positioning ring 501 is sleeved on the surface of the bottom positioning post 4 to limit the self-locking rod 304. A pin 502 is provided on both sides of the positioning ring 501. The pin 502 is adapted to the limiting hole on the surface of the positioning post 4. Pulling the handle 504 on one side of the pin 502 will cause the pin 502 to move due to the elastic potential energy provided by the buffer spring 503 until the positioning ring 501 moves to the appropriate position. Then, the handle 504 is released and the pin 502 is inserted into the limiting hole on the surface of the positioning post 4.

[0034] Specifically, a buffer spring 503 is sleeved on the surface of the pin 502, and a handle 504 is fixedly connected to one side of the pin 502.

[0035] Specifically, one side of the buffer spring 503 is fixedly connected to the surface of the positioning ring 501, and the other side of the buffer spring 503 is fixedly connected to the surface of the handle 504.

[0036] In this implementation scheme, since the self-locking rod 304 will wear out during long-term use and needs to be replaced and maintained regularly, a positioning ring 501 is sleeved on the surface of the bottom positioning post 4 to limit the self-locking rod 304. A pin 502 is provided on both sides of the positioning ring 501. The pin 502 is adapted to the limiting hole on the surface of the positioning post 4. Pulling the handle 504 on one side of the pin 502 will cause the pin 502 to move due to the elastic potential energy provided by the buffer spring 503 until the positioning ring 501 moves to the appropriate position. Then, the handle 504 is released and the pin 502 is inserted into the limiting hole on the surface of the positioning post 4.

[0037] Specifically, the self-locking block 302 has sliders 6 on both sides, which are slidably connected to the grooves opened in the inner wall of the mounting housing 1. The top of the self-locking block 302 is fixedly connected to two connecting rods 7, and a connecting plate 8 is installed on the top of the connecting rods 7. A press button 9 is provided on the surface of the connecting plate 8.

[0038] Specifically, threaded holes are provided on both sides of the surface of the mounting housing 1, and positioning bolts 10 are connected to the internal threads of the threaded holes.

[0039] The working principle and usage process of this utility model are as follows: When in use, press the top pressing button 9. The pressing button 9 drives the bottom self-locking block 302 to slide inside the mounting housing 1 through the connecting rod 7. The self-locking block 302 squeezes the bottom support spring 301 and drives the self-locking rod 304 in the surface limiting slide rail 303 to slide inside. When the self-locking rod 304 slides to the top of the limiting slide rail 303, the self-locking rod 304 will be stuck in its groove. If you continue to press down, the self-locking rod 304 will move again until it moves out of the groove and returns to the starting position at the bottom.

[0040] During use, the self-locking rod 304 will wear out during long-term operation and needs to be replaced and maintained regularly. Therefore, a positioning ring 501 is sleeved on the surface of the bottom positioning post 4 to limit the self-locking rod 304. The positioning ring 501 is used to limit the position of the self-locking rod 304. Pins 502 are set on both sides of the positioning ring 501. The pins 502 are matched with the limiting holes on the surface of the positioning post 4. Pulling the handle 504 on one side of the pin 502 will cause the pin 502 to move due to the elastic potential energy provided by the buffer spring 503 until the positioning ring 501 moves to the appropriate position. Then, the handle 504 is released and the pin 502 is inserted into the limiting hole on the surface of the positioning post 4.

[0041] In summary, this switch operating mechanism achieves a self-locking effect through the self-locking mechanism 3, which is simple in structure and easy to operate. Through the disassembly and assembly mechanism 5, the self-locking rod 304 can be quickly disassembled and assembled without the need for bolts, thus improving the disassembly and assembly efficiency of the staff.
