Description

Plug anti-drop socket

Technical Field

The invention relates to the technical field of sockets, in particular to a plug anti-falling socket.

Background

The socket is the most basic electric device in the current household or industrial electric network, and mainly comprises a socket and a jack arranged on the socket, wherein a copper sheet contact groove matched with a plug metal sheet is arranged in the jack, and a metal sheet electrode is connected to an electric input end.

In the technical field of electrical appliance sockets, the socket can be inevitably loosened when being plugged and pulled for a long time, and a plug is easy to fall off along with the shaking of a data line; part of plugs are not matched with the existing sockets, and the plugs are easy to loosen when used for the first time; the plug is also likely to slip out in the presence of vibration.

The patent application number is CN201210047885.1, the patent name is "anti-drop socket and its pull-out locking mechanism", which discloses a rolling type clamping locking mechanism, but it adopts two sets of springs to maintain the stability of the roller, two plugs are corresponding to one set of two springs, if the matching between two springs of the same set is asynchronous, one is blocked, then two rollers of the locking plug will appear one high and one low, and the locking action disappears; in addition, if the external force is too large, the plug is too tightly held by the roller, and the mechanism is difficult to press the roller down, and even the related structural elements are damaged.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: in order to solve the problems that a plug is easy to slide and separate from a socket, an anti-drop socket and a roller of a pull-out locking mechanism of the anti-drop socket are asynchronous and easy to lose efficacy, and the roller is too tightly embraced to damage related structural elements in the prior art, the anti-drop socket is provided.

The technical scheme adopted by the invention for solving the technical problems is as follows: a plug anti-drop socket is characterized in that a copper sheet contact groove is arranged in the socket, a metal sheet matched with the copper sheet contact groove is arranged on a plug, and the metal sheet and the copper sheet contact groove are in one-to-one correspondence;

clamping mechanisms are uniformly arranged above the copper sheet contact grooves and comprise two swinging parts, the swinging parts are symmetrically arranged and are rotatably connected with the socket, sliding grooves extending along the length direction of the swinging parts are formed in the swinging parts, rollers are slidably arranged in the sliding grooves, each clamping mechanism is internally provided with an elastic sheet for enabling the two rollers to be close to each other, the end parts of the elastic sheets are fixedly connected with the corresponding rollers, a gap for the metal sheet to pass through is formed between the two rollers of the same clamping mechanism, the metal sheet passes through the gap between the two rollers and then is inserted into the corresponding copper sheet contact groove, the rollers are arranged on the swinging parts, the locking or releasing of the metal sheet is realized through the change of the position state of the swinging parts, and on one hand, the plug can be prevented from being separated from the socket, on the other hand, the elastic sheet is convenient to release after being locked, and the two rollers connected with the elastic sheet can synchronously move to a certain extent, so that the situation that the metal sheet cannot be clamped due to the fact that the rollers on the two sides of the metal sheet have height difference is prevented;

the socket is also internally provided with an unlocking mechanism which is used for enabling the swinging pieces on two sides of the same metal sheet to deflect so as to drive the rollers on the two swinging pieces to overcome the elasticity of the elastic sheet and to be away from each other, and the swinging pieces are adopted to rotate to open and release the metal sheet, so that the situation that the mechanism locks the metal sheet and cannot release the metal sheet is avoided.

In order to solve the problems of how to arrange the unlocking mechanism and realize the deflection of the swinging piece, the unlocking mechanism further comprises a left push rod and a right push rod; the left end of the left push rod is positioned outside the socket, the right end of the left push rod is positioned inside the socket, and the swinging pieces positioned on the left side of the metal sheet are hinged with the right end of the left push rod; the right-hand member of right push rod is located outside the socket, the left end of right push rod is located the socket, and the swinging member that is located the sheetmetal right side all is articulated with the left end of right push rod, makes the swinging member of sheetmetal both sides take place to deflect through promoting left push rod and right push rod to the roller that drives on two swinging members overcomes the elasticity of elastic sheet and keeps away from each other, removes the fixing of two rollers to the sheetmetal that it corresponds among the same clamping mechanism, thereby guarantees the stability of sheetmetal and takes out.

In order to solve the problem of the installation of the swinging part in the socket, the socket is internally fixed with a support frame, the swinging part in the socket is rotatably installed on the support frame, the support frame is of a trapezoidal structure, and a rotating fulcrum is provided for the swinging part through the installation of the support frame.

The invention has the beneficial effects that: according to the plug anti-drop socket provided by the invention, the roller is arranged on the swinging piece, and the roller locks or releases the metal sheet through the change of the position state of the swinging piece, so that the plug can be prevented from being separated from the socket, the metal sheet can be conveniently released after being locked, the swinging piece is adopted to rotate to open and release the metal sheet, and the situation that the mechanism locks the metal sheet and cannot release the metal sheet is avoided.
