Technical Field
[0001] The utility model relates to the technical field of sockets, and in particular to a socket with a traction self-locking structure. Background Art
[0002] A socket, also known as a power socket or a switch socket, refers to a seat into which one or more circuit wiring can be inserted. Various wiring can be inserted into it to facilitate connection with other circuits. The connection and disconnection between the lines and the conductive parts can ultimately achieve the connection and disconnection of this part of the circuit.
[0003] When a plug is inserted into an existing socket for charging, the plug is easily loosened due to external pulling, thereby causing it to fall off the socket. For this reason, people have designed a socket that can lock the position of the plug. However, although this type of socket can lock the position of the plug when in use, it requires the user to manually lock or unlock the position of the plug when in use. This method increases the number of operating steps, thereby affecting the convenience of use. Utility Model Content
[0004] The purpose of the utility model is to provide a socket with a traction self-locking structure, so as to solve the problem that when the plug is inserted into the socket for charging, the existing socket in the prior art is very easy to become loose due to external pulling, thereby causing the plug to fall off the socket. For this reason, people have designed a socket that can lock the position of the plug. However, although this type of socket can lock the position of the plug when in use, it requires the user to manually lock or unlock the position of the plug when in use. This method increases the operation steps, thereby affecting the convenience of use.
[0005] The utility model provides the following technical solution: a socket with a traction self-locking structure, comprising a base plate, two mounting plates with mounting holes are fixedly connected to the two sides of the base plate respectively, a socket is arranged on the top of the base plate, a plug is plugged into the inner side of the socket, a locking mechanism for locking the plug is arranged on the top of the base plate, and an adjusting mechanism for adjusting the position of the locking mechanism is also arranged on the top of the base plate.
[0006] As a preferred embodiment of the above technical solution, a socket is provided on the inner side of the socket, and the plug is plugged into the inner side of the socket.
[0007] As a preferred embodiment of the above technical solution, the adjustment mechanism includes two symmetrically distributed grooves opened on the top of the base plate, the inner side of the groove is rotatably connected with a bidirectional screw, the external thread of the bidirectional screw is connected with a fixing frame, the end of the fixing frame away from the bidirectional screw is slidably connected with a limiting rod, and the outer end of the bidirectional screw is fixedly connected with a handle. When in use, the user can install the base plate at the specified position through the mounting plate and the mounting bolts, and then insert the plug into the socket. Then the user can turn the handle. The rotation of the handle drives the bidirectional screw to rotate, and the rotation of the bidirectional screw drives the two fixing frames to move through the limiting rod. The movement of the fixing frame drives the locking mechanism to move. Then the user can move the two fixing frames to the specified position according to the size of the plug, thereby achieving the effect of using plugs of different sizes, thereby improving the applicability of the socket.

[0009] As a preferred embodiment of the above technical solution, the locking mechanism includes a rotating shaft rotating on the inner side of the top of the two fixing frames, the outside of the rotating shaft is fixedly connected with a return spring, the end of the return spring away from the rotating shaft is fixedly connected with a fixed plate, the outside of the rotating shaft is fixedly connected with a baffle, the bottom of the baffle is fixedly connected with two supports, the outside of the support is rotatably connected with a connecting rod, the end of the connecting rod away from the support is fixedly connected with a slide plate, the outside of the connecting rod is slidably connected to a fixed cylinder, a non-Newtonian fluid is arranged on the inside of the fixed cylinder, and the end of the fixed cylinder away from the connecting rod is fixedly connected with a bracket. When in use, the user can install the bottom plate through the mounting plate and the mounting bolts, and then adjust the position of the locking mechanism through the adjusting mechanism. Then, when the plug is pulled, the plug moves rapidly, and the plug moves It will contact the baffle on the outside of the rotating shaft. At this time, the baffle and the rotating shaft will rotate. The rotation of the rotating shaft will stretch the return spring, and the movement of the baffle will drive the movement of the support. The movement of the support will drive the movement of the connecting rod. The movement of the connecting rod will drive the movement of the skateboard. The movement of the skateboard will squeeze the non-Newtonian fluid in the fixed cylinder. Because the shear force of the skateboard on the non-Newtonian fluid is relatively large when the plug is subjected to pulling force, the non-Newtonian fluid will form a large resistance to the skateboard. At this time, the skateboard will be affected and cannot move in the fixed cylinder. At this time, the baffle is affected by the skateboard and cannot rotate anymore. At this time, the baffle can lock the plug, so that when the plug is pulled, the position of the plug can be locked, thereby avoiding the problem of separation of the plug and the socket, and there is no need to manually lock the plug.

When in use, the user can install the base plate at a specified position through the mounting plate and the mounting bolts, and then insert the plug into the socket. Then the user can turn the handle, and the rotation of the handle drives the two-way screw to rotate, and the rotation of the two-way screw drives the two fixing frames to move through the limit rod, and the movement of the fixing frame drives the locking mechanism to move, and then the user can move the two fixing frames to the specified position according to the size of the plug. When the plug is pulled and pulled, the plug moves rapidly, and the movement of the plug will contact the baffle plate outside the rotating shaft. At this time, the baffle plate and the rotating shaft will rotate, and the rotation of the rotating shaft will stretch the return spring, and the movement of the baffle plate will drive the movement of the support, and the movement of the support will drive the movement of the connecting rod. The movement will drive the skateboard to move, and the movement of the skateboard will squeeze the non-Newtonian fluid in the fixed cylinder. When the plug is subjected to pulling force, the shear force of the skateboard on the non-Newtonian fluid is relatively large. At this time, the non-Newtonian fluid will form a large resistance to the skateboard. At this time, the skateboard will be affected and cannot move in the fixed cylinder. At this time, the baffle plate is affected by the skateboard and cannot rotate anymore. At this time, the baffle plate can lock the plug, so that when the plug is pulled, the position of the plug can be locked, thereby avoiding the problem of the plug being separated from the socket when it is pulled. At the same time, there is no need to manually lock the plug, and the position of the locking mechanism can also be adjusted through the adjustment mechanism, so as to facilitate the use of plugs of different sizes, further improving the scope of application of the device.
