Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, specifically a safety switch that is easy to disassemble and install. Background Technology

[0002] In electrical systems, safety switches play a crucial role, promptly cutting off current in case of circuit abnormalities to ensure the safety of personnel and equipment. However, existing safety switches present numerous inconveniences in terms of installation and disassembly. A current patent, CN215377254U, describes a safety switch housing designed for easier installation. It includes a housing with an opening on one side and a top cover that fits over the opening. The bottom of the housing has a cable outlet, through which a cable retaining sleeve passes. The outer surface of the opening has outwardly protruding and continuous reinforcing ribs. The side of the top cover facing the opening has a groove for the reinforcing ribs to be inserted. A snap-fit ​​structure connects the top cover and the opening, allowing the top cover to be fastened to the opening and cover the housing. The reinforcing ribs and groove seal the edges of the housing. The cable passes through the cable retaining sleeve. This simplified structure eliminates the need for a self-contained internal threaded demolding device after optimizing the cable outlet, improving production efficiency. The entire structure is simple and easy to assemble, significantly simplifying the original structure and assembly method. The injection mold is also simplified accordingly, resulting in a substantial reduction in overall production and assembly costs. The production and assembly costs of safety switches using this type of safety switch housing are also significantly reduced.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When existing safety switches are used, the lack of an effective quick-clamping structure during assembly makes the assembly of safety switches inefficient and limited. Therefore, we propose a safety switch that is easy to disassemble and install to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety switch that is easy to disassemble and install. It solves the problem that existing safety switches are inefficient and have limitations when assembled due to the lack of an effective quick-clamping structure.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a safety switch that is easy to disassemble and install, comprising two opposing mounting bases, a main lock is installed inside the mounting base located on the left side, two guide block assemblies with protruding structures are fixedly connected to the upper and lower sides of the main lock, and a partition assembly is fixedly connected to the rear side of the main lock.

[0006] A servo motor is mounted on the outside of the partition assembly. A transmission screw is mounted on the output shaft of the servo motor via a coupling. A lock tongue assembly is installed inside the main lock. The lock tongue assembly has a screw hole that matches the transmission screw. Protrusion assemblies with outward protrusions are fixedly connected to both the upper and lower sides of the lock tongue assembly.

[0007] Preferably, a cylindrical insert rod assembly is fixedly connected to the rear side of the mounting base, and a screw hole is provided in the insert rod assembly away from the mounting base.

[0008] Preferably, an L-shaped bracket assembly is fixedly connected to the front end face of the mounting base. Each pair of longitudinally adjacent bracket assemblies forms a group, and the two groups of bracket assemblies are fixedly connected to the front end faces of the two mounting bases in opposite directions.

[0009] Preferably, a pressing push rod is fixedly connected to the rear side of the two sets of bracket assemblies, and a circular pressure plate assembly is fixedly connected to the rear output end of the pressing push rod.

[0010] Preferably, a secondary lock is inserted into the inner side of the mounting base on the right side, and two slots are formed in a straight line on the front end face of both the secondary lock and the main lock.

[0011] Preferably, a slider assembly is fixedly connected to the outer side of the secondary lock, and there are two slider assemblies in total.

[0012] Preferably, the two slider assemblies are fixedly connected to the upper and lower sides of the two auxiliary locks in opposite directions, and the auxiliary locks are inserted into the mounting base through the slider assemblies.

[0013] Beneficial effects

[0014] This invention provides a safety switch that is easy to disassemble and install. Compared with the prior art, it has the following advantages:

[0015] This easy-to-disassemble and install safety switch ensures the stability of the safety switch connection through the coordinated operation of components such as the main lock, the auxiliary lock, and the clamping push rod. The locking tongue assembly of the main lock is precisely locked under the drive of the servo motor and the transmission screw. The auxiliary lock and the main lock are engaged through a slot, and with the clamping action of the clamping push rod and the pressure plate assembly, the entire switch will not easily loosen during use. This effectively avoids safety hazards such as poor contact and accidental power outage caused by switch loosening, effectively protects the safety of personnel and equipment, and makes up for the lack of an effective and quick clamping structure in existing safety switches.

[0016] This easy-to-disassemble and install safety switch greatly simplifies the installation and disassembly process through its cleverly designed plug-in assembly, slider assembly, and other structures. During installation, the secondary lock can be quickly inserted into the mounting base using the slider assembly. Compared to traditional safety switches that require complex screw tightening operations, this saves a lot of time and effort. Disassembly is also simple, requiring only the reverse operation to easily separate the components. This solves the problem of low assembly efficiency in existing safety switches and significantly improves operational convenience. Attached Figure Description

Detailed Implementation

[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 Figures 1-6This utility model provides a technical solution: a safety switch that is easy to disassemble and install, including two opposing mounting bases 1. The main lock 3 is installed inside the mounting base 1 on the left side. The upper and lower sides of the main lock 3 are fixedly connected to two protruding guide block assemblies 301. The rear side of the main lock 3 is fixedly connected to a partition assembly 3011.

[0026] A servo motor 3012 is installed on the outside of the partition assembly 3011. A transmission screw 3013 is mounted on the output shaft of the servo motor 3012 via a coupling. A lock tongue assembly 3014 is installed inside the main lock 3. A screw hole matching the transmission screw 3013 is opened inside the lock tongue assembly 3014. A protruding block assembly 3015 with an external protrusion structure is fixedly connected to both the upper and lower sides of the lock tongue assembly 3014.

[0027] By setting a main lock 3 in the mounting base 1 on the left side, the main lock 3 is connected to the guide block assembly 301 and the partition assembly 3011. A servo motor 3012 is installed on the outside of the partition assembly 3011 to drive the transmission screw 3013, which cooperates with the lock tongue assembly 3014 to build a core locking drive structure for the safety switch, realizing the automatic locking function of the switch and providing basic support for subsequent installation and disassembly operations.

[0028] See Figures 1-4 A cylindrical insert rod assembly 101 is fixedly connected to the rear side of the mounting base 1. A screw hole is provided in the insert rod assembly 101 away from the mounting base 1.

[0029] By providing a plug assembly 101 on the rear side of the mounting base 1 and opening a screw hole in it away from the mounting base 1, the mounting base 1 can be stably connected and fixed to external equipment through the plug assembly 101, thereby enhancing the stability of the entire safety switch installation.

[0030] See Figures 2-3 An L-shaped bracket assembly 1011 is fixedly connected to the front end face of the mounting base 1. Every two longitudinally adjacent bracket assemblies 1011 form a group, and the two groups of bracket assemblies 1011 are fixedly connected to the front end faces of the two mounting bases 1 in opposite directions.

[0031] By setting an L-shaped bracket assembly 1011 on the front face of the mounting base 1 and fixing it in two opposing positions, a support structure is provided for the subsequent installation of components such as the clamping push rod 1012, which helps to realize the clamping and fixing function of other components, thereby improving the overall stability of the safety switch structure.

[0032] See Figures 4-6 Two sets of bracket assemblies 1011 are fixedly connected to the rear side of a pressing push rod 1012, and a circular pressure plate assembly 1013 is fixedly connected to the rear output end of the pressing push rod 1012.

[0033] The clamping push rod 1012 and the pressure plate assembly 1013 are connected to the rear side of the two sets of bracket assemblies 1011. When the clamping push rod 1012 is working, the pressure plate assembly 1013 can apply pressure to the parts that need to be fixed, thereby playing a clamping and fixing role and further enhancing the stability and reliability of the safety switch after installation.

[0034] See Figures 1-2 The inner side of the mounting base 1 on the right is connected to the auxiliary lock 2. The front surfaces of the auxiliary lock 2 and the main lock 3 are provided with two slots 201 in a straight array.

[0035] By inserting the auxiliary lock 2 into the inner side of the mounting base 1 on the right side, and opening the slot 201 on the front end face of the auxiliary lock 2 and the main lock 3, the auxiliary lock 2 cooperates with the main lock 3, and the slot 201 can be used to snap into other components, realizing the combined installation of multiple components of the safety switch, and improving the integrity and stability of the switch structure.

[0036] See Figures 5-6 The outer side of the secondary lock 2 is fixedly connected to a slider assembly 2011, which has two locations.

[0037] By fixing two slider assemblies 2011 on the outside of the secondary lock 2, the secondary lock 2 can be more easily inserted into the mounting base 1 through the slider assemblies 2011, which optimizes the installation method of the secondary lock 2 and facilitates the assembly and disassembly of the safety switch.

[0038] See Figures 1-2 Two slider assemblies 2011 are fixedly connected to the upper and lower sides of two auxiliary locks 2 in opposite directions. The auxiliary locks 2 are inserted into the mounting base 1 through the slider assemblies 2011.

[0039] By clarifying the opposing fixed positions of the two slider assemblies 2011 on the upper and lower sides of the auxiliary lock 2, the structural stability of the auxiliary lock 2 being inserted into the mounting base 1 through the slider assembly 2011 is further emphasized, ensuring the installation accuracy and reliability of the auxiliary lock 2 in the mounting base 1, which is conducive to the overall performance of the safety switch.

[0040] During operation, before installing the safety switch, the mounting base 1 is initially positioned using the plug assembly 101. The plug assembly 101 is fixed to the rear side of the mounting base 1, and a screw hole is provided inside it away from the mounting base 1. Bolts and other connectors can be used to fix the mounting base 1 in the target position, providing a stable foundation for the subsequent installation of other components.

[0041] The main lock 3 located inside the mounting base 1 on the left side has guide block assemblies 301 on its upper and lower sides that play a guiding and stabilizing role. A servo motor 3012 is installed on the partition assembly 3011 on the rear side of the main lock 3. The output shaft of the servo motor 3012 is connected to the transmission screw 3013 through a coupling. When it is necessary to control the movement of the lock tongue assembly 3014, the servo motor 3012 is started.

[0042] The servo motor 3012 drives the transmission screw 3013 to rotate. Since the lock tongue assembly 3014 has a screw hole that matches the transmission screw 3013, the rotation of the transmission screw 3013 will cause the lock tongue assembly 3014 to move back and forth along the track inside the main lock 3. The protrusion assemblies 3015 on the upper and lower sides of the lock tongue assembly 3014 play a role in assisting positioning and preventing the lock tongue assembly 3014 from shaking during the movement, ensuring that the lock tongue assembly 3014 can accurately cooperate with other components to achieve the locking function.

[0043] The auxiliary lock 2 is inserted into the inner side of the mounting base 1 on the right. The slider assembly 2011 on the outer side of the auxiliary lock 2 plays a key role. There are two slider assemblies 2011, which are fixed to the upper and lower sides of the auxiliary lock 2 in opposite directions, so that the auxiliary lock 2 can be smoothly inserted along the slide inside the mounting base 1, making it convenient and quick to install the auxiliary lock 2. The front end face of both the auxiliary lock 2 and the main lock 3 has a slot 201 for engaging with other components that need to be connected.

[0044] The L-shaped bracket assembly 1011 is fixed on the front face of the mounting base 1. Each pair of brackets is longitudinally adjacent and the two pairs are fixed to the front face of the mounting base 1 at two different locations. The clamping push rod 1012 is connected to the rear side of the bracket assembly 1011. When it is necessary to further fix other components, the clamping push rod 1012 is activated, and the pressure plate assembly 1013 at its rear output end will apply pressure to the target component, thereby enhancing the stability of the entire safety switch after installation.

[0045] In summary, this device, by incorporating a main lock 3 and a secondary lock 2, enables rapid connection and combination.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
