Safety power socket with double locking and single hole insertion prevention

Abstract

This utility model relates to the field of safety power socket technology, specifically a double-locking safety power socket that prevents single-hole insertion. The socket includes a guide rod installed next to the back of multiple sockets. Each guide rod has a slidably mounted sealing spring corresponding to the position of the socket. The advantages of this utility model are: guide rods are installed next to the sockets on the back of the socket, sealing springs are slidably mounted on the guide rods, and limiting springs are slidably mounted between two adjacent guide rods. A spring is also fitted around the outside of the guide rods. In use, when a foreign object is inserted into a socket, its position is locked by the guide rod under the action of the limiting spring, preventing the sealing spring from moving downwards, effectively preventing the insertion of foreign objects. Only when foreign objects are inserted into two sockets can the limiting springs move, allowing the foreign object to contact the contacts. This improves the safety of the socket to a certain extent. Furthermore, the component has a simple structure and is convenient for operators to use.

Description

Technical Field

[0001] This utility model relates to the field of safety power socket technology, and in particular to a double-locking safety power socket that prevents single-hole insertion. Background Technology

[0002] A socket is a socket with one or more circuit wires that can be inserted. Various wires can be inserted through it. However, if a child or other person accidentally inserts a metal rod or other object into the live wire hole, it will form a closed circuit with the human body, resulting in electric shock. Based on this, this application proposes a double-locking safety power socket to prevent single-hole insertion, which can solve the above problem. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a safety power socket with double locking to prevent single-hole insertion.

[0004] The purpose of this utility model is achieved through the following technical solution: a safety power socket with double locking to prevent single-hole insertion, including a socket, wherein guide rods are installed on the back of multiple sockets of the socket, and a sealing spring is slidably installed on the outside of the multiple guide rods, corresponding to the position of the socket, and a limiting spring is slidably installed between two adjacent guide rods, which is located below the sealing spring, and a spring is sleeved on the outside of the multiple guide rods, which is located below the limiting spring.

[0005] Optionally, multiple mounting holes are provided next to the socket on the back of the socket, and multiple guide rods are respectively threaded into the multiple mounting holes.

[0006] Optionally, limit caps are installed on the outer ends of the plurality of guide rods.

[0007] Optionally, all of the aforementioned closed springs are bent into an arc shape with the convex side facing upwards.

[0008] Optionally, the center of each of the plurality of limiting springs is bent upward in an arc shape.

[0009] This utility model has the following advantages:

[0010] This double-locking, single-hole insertion-proof safety power socket features guide rods installed next to the sockets on the back of the socket. A sealing spring is slidably mounted on the guide rod, and a limiting spring is slidably mounted between two adjacent guide rods. A spring is also fitted around the outside of the guide rods. During use, when a foreign object is inserted into one socket, its position is locked by the guide rod under the action of the limiting spring, preventing the sealing spring from moving downwards and effectively preventing the insertion of foreign objects. Only when foreign objects are inserted into both sockets can the limiting spring move, allowing the foreign object to contact the contacts. This improves the safety of the socket to a certain extent. Furthermore, the component has a simple structure, making it convenient for operators to use. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0017] like Figures 1 to 4 As shown, a double-locking safety power socket that prevents single-hole insertion includes a socket 1. Each of the multiple sockets of the socket 1 has a guide rod 2 installed on the back side. Each of the multiple guide rods 2 has a sealing spring 5 slidably installed on its exterior, corresponding to the position of the socket. Each of the two adjacent guide rods 2 has a limiting spring 6 slidably installed between them, which is located below the sealing spring 5. Each of the multiple guide rods 2 has a spring 4 sleeved on its exterior, which is located below the limiting spring 6.

[0018] As an optional technical solution of this utility model, multiple mounting holes 7 are provided next to the socket on the back of the socket 1, and multiple guide rods 2 are respectively threaded into the multiple mounting holes 7. This facilitates the installation and disassembly of the guide rods 2, and makes it convenient for users to disassemble and maintain them later.

[0019] As an optional technical solution of this utility model, limit caps 3 are installed on the outer ends of multiple guide rods 2, which can block the position of spring 4 to ensure that the position of spring 4 is appropriate. The limit caps 3 and guide rods 2 can be threaded together to facilitate assembly and disassembly.

[0020] As an optional technical solution of this utility model, multiple sealing springs 5 ​​are all bent into an arc shape with the convex surface facing upward. This allows the sealing springs 5 ​​to have a certain deformation space, so that when they are deformed, they will not affect the contact between the plug and the contact point.

[0021] As an optional technical solution of this utility model, the middle of the multiple limiting springs 6 are all bent upward in an arc shape, which can provide a certain elastic force to the limiting springs 6, so that they are squeezed together with the guide rod 2, increasing the friction between the two and preventing them from moving downward after being subjected to force on one side.

[0022] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: A guide rod 2 is installed next to the socket on the back of the socket 1. A sealing spring 5 is slidably installed on the guide rod 2. A limiting spring 6 is slidably installed between two adjacent guide rods 2. A spring 4 is also sleeved on the outside of the guide rod 2. When a foreign object is inserted into a socket, its position will be blocked by the guide rod 2 under the action of the limiting spring 6, preventing the sealing spring 5 from moving down, which can effectively prevent the insertion of foreign objects. Only when foreign objects are inserted into two sockets can the limiting spring 6 move, allowing the foreign object to contact the contact point, which improves the safety of the socket 1 to a certain extent. Moreover, the component has a simple structure and is convenient for workers to use.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
