[0004] The aforementioned patent describes a safety switch. In the prior art, safety switches are fixed to the mounting surface by setting mounting holes in the housing, which can be connected and fixed with the mounting surface by screws. However, during installation and disassembly, tools are required, which is cumbersome and increases the workload. Therefore, we propose a safety switch housing structure that is easy to install to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a safety switch housing structure that is easy to install, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a safety switch housing structure that is easy to install, including a housing, a key interface, an operating key, and a quick-release mechanism. The housing has a key interface at the lock head, and an operating key is movably inserted into the inner side of the key interface. The housing has a quick-release mechanism at the bottom, which includes a base frame, a mounting base, a fixed frame, a rebound assembly, a telescopic shaft, a movable frame, inserts, and slots. The base frame is supported at the bottom of the housing, and the mounting base is connected to the rear side of the base frame. A fixed frame is integrally provided on the right side of the base frame, and a rebound assembly is embedded in the left side of the base frame. A telescopic shaft is telescopically provided on the left side of the rebound assembly, and the end of the telescopic shaft is screwed to the movable frame. The housing is snapped and fixed between the movable frame and the fixed frame. Inserts are symmetrically arranged on the front and rear sides of the movable frame and the fixed frame. The inserts are horizontally arranged. Slots are provided on both the left and right sides of the housing, and the slots are symmetrically arranged on the front and rear sides of the housing. The inserts and slots are horizontally inserted.

[0007] Preferably, the surface of the housing has mounting holes.

[0008] Preferably, the connection length between the insert and the slot is not less than 10mm.

[0009] Preferably, the telescopic stroke of the telescopic shaft is not less than twice the length of the insert.

[0010] Preferably, the total number of slots is not less than 4, and the number of inserts is the same as the number of slots.

[0011] Preferably, the inner walls of both the movable frame and the fixed frame are fitted with rubber pads, and the thickness of the rubber pads is not less than mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a quick-assembly / disassembly mechanism at the bottom of the casing. By placing the casing on top of the base frame and then pushing the movable frame to trigger the rebound assembly, the telescopic shaft retracts, locking the casing between the movable and fixed frames. Simultaneously, the inserts on the movable and fixed frames can be inserted into slots on both sides of the casing, thus assembling and fixing the casing to the base frame. No tools are required during casing installation, enabling rapid assembly. For disassembly, simply push the movable frame to trigger the rebound assembly, popping out the telescopic shaft and increasing the distance between the movable and fixed frames, allowing the casing to be removed from the top of the base frame. No tools are needed for disassembly, enabling rapid removal of the casing. Attached Figure Description

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1 This utility model provides a safety switch housing structure that is easy to install, including a housing 1, a key interface 2, an operating key 3, and a quick-release mechanism 4. The housing 1 has a key interface 2 at the lock head, and the operating key 3 is movably inserted into the inside of the key interface 2. The operating key 3 cooperates with the key interface 2 to achieve a magnetic locking function. The housing 1 has a quick-release mechanism 4 at the bottom.

[0021] Please see Figure 2-4 This utility model provides a safety switch housing structure that is easy to install. The quick-release mechanism 4 includes a base frame 41, a mounting base 42, a fixing frame 43, a rebound assembly 44, a telescopic shaft 45, a movable frame 46, a insert 47, and a slot 48. The base frame 41 is supported on the bottom of the housing 1. The mounting base 42 is connected to the rear side of the base frame 41. The fixing frame 43 is integrally provided on the right side of the base frame 41. The rebound assembly 44 is embedded in the left side of the base frame 41. The telescopic shaft 45 is telescopically provided on the left side of the rebound assembly 44. 5. The end of the telescopic shaft 45 is screwed to the movable frame 46. The housing 1 is snapped and fixed between the movable frame 46 and the fixed frame 43. The movable frame 46 and the fixed frame 43 are symmetrically provided with inserts 47 on their front and rear sides. The inserts 47 are horizontally arranged. The left and right sides of the housing 1 are provided with slots 48, which are symmetrically arranged at the front and rear of the housing 1. The inserts 47 and the slots 48 are horizontally inserted to snap the housing 1 between the movable frame 46 and the fixed frame 43, thereby achieving assembly and fixation.

[0022] To further explain, the surface of the housing 1 has mounting holes, and users can choose to install with screws or the quick-release mechanism 4 according to their needs. This does not conflict with the original installation method and has strong applicability.

[0023] To further clarify, the connection length between the insert 47 and the slot 48 is not less than 10mm to ensure connection stability.

[0024] To further clarify, the telescopic stroke of the telescopic shaft 45 is not less than twice the length of the insert 47.

[0025] To further clarify, there are no fewer than four slots 48, and the number of inserts 47 is the same as the number of slots 48, ensuring a stable assembly.

[0026] To further explain, rubber pads 49 are fitted to the inner walls of both the movable frame 46 and the fixed frame 43. The rubber pads 49 are not less than 4mm thick and can fill the gaps on both sides of the housing 1, ensuring that the installation is stable and not easily loosened.

[0027] The working principle is as follows:

[0028] First, the base frame 41 is fixed to the mounting surface with screws on the mounting base 42. When installing the housing 1, the movable frame 46 is pushed to trigger the rebound assembly 44 to pop out the telescopic shaft 45, increasing the distance between the movable frame 46 and the fixed frame 43. Then, the housing 1 is placed on top of the base frame 41. Then, the movable frame 46 is pushed again to trigger the rebound assembly 44 to retract the telescopic shaft 45, so that the housing 1 is locked between the movable frame 46 and the fixed frame 43. At the same time, the inserts 47 on the movable frame 46 and the fixed frame 43 can be inserted and fixed with the slots 48 on both sides of the housing 1, thereby assembling and fixing the housing 1 and the base frame 41. The housing 1 can be installed quickly without the aid of tools.

[0029] During disassembly, simply push the movable frame 46 to trigger the rebound assembly 44 to pop out the telescopic shaft 45, increasing the distance between the movable frame 46 and the fixed frame 43, and the housing 1 can be removed from the top of the base frame 41 to complete the disassembly. No tools are needed during the disassembly of the housing 1, which can achieve quick disassembly.
