Abstract

The utility model relates to a clamp type plug socket with anti-loose function. The plug comprise a casing body and a plugging piece, spring clips are symmetrically arranged at the middle part of the casing body, a hook-shaped clamping head is arranged at the front end of a handle on the spring clip, and a groove is arranged at the middle position of the casing body. Outwards convex grooves are arranged at the upper part and the lower part of plug jacks in the socket. The utility model has the advantages that the structure is simple, the operation is convenient, the firm contact between a plug and the socket is ensured, the plug is uneasy to be loose, and the mistake pulling of the plug can be prevented, an electric appliance which is damaged and the occurrence of accidents can be avoided, the applicable ranger is wide, thus being helpful to the safe production and life.

Description

A kind of folder formula plugs and sockets

Technical field

The utility model relates to a kind of plugs and sockets, especially relates to a kind of folder formula plug with slip-off preventing function and inserts the formula seat.

Background technology

Existing electric equipment plug and socket of power source utilizes the interior shell fragment of socket that the clamping action of inserted sheet is prevented that plug from coming off usually, but because clamping action is too small, cause plug to come off automatically easily, or be pulled out unintentionally, bring inconvenience, there is potential safety hazard in infringement electrical equipment.Though some technology have appearred in succession, as ZL02235393.3 by spring to lacing film and plug to the hook catch on mutually, prevented that to a certain extent plug from being pulled, but it uses comparatively complicated, need two manual manipulations, and more to the change of ordinary plug socket, make comparatively complicated.

Summary of the invention

Goal of the invention of the present utility model is at above-mentioned defective, improves the safe handling structure of plugs and sockets, and a kind of folder formula plugs and sockets with slip-off preventing function is provided, and realizes the safe design of electric equipment annex, helps safety in production and life, and is significant.

The technical solution of the utility model is: a kind of folder formula plugs and sockets, and plug comprises housing and inserted sheet, the middle part of housing is arranged with spring clip.

Above-mentioned spring clip is made up of handle, auricle, spring, fulcrum, and described auricle is connected on the housing, and links mutually with the fulcrum that is with spring in handle; Described both ends of the spring is provided with outer adjutage and interior adjutage; Described handle front end is provided with hooked keeper, and the front center position of housing has groove.

The position, upper and lower part of jack is respectively equipped with evagination hook-type groove in the above-mentioned socket.

The beneficial effects of the utility model are: simple in structure, easy to use, and can prevent effectively that plug from contacting with socket inadequately firmly and come off, and can prevent that mistake from pulling out plug, avoid damaging electrical equipment and security incident takes place, safe and reliable.

The utility model has wide range of applications, and is applicable to the electric equipment safety attachment of school, dwelling house, office building etc., helps safety in production and life, and is significant.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Referring to Fig. 1 to Fig. 3, the utility model plug comprises housing 1, inserted sheet 2, housing 1 middle part opposite position is equipped with a spring clip 3 respectively, this spring clip 3 is by handle 7, auricle 4, spring 5, fulcrum 6 is formed, wherein auricle 4 is connected on the housing 1, auricle 4 is penetrated with axis hole 8, handle 7 is linked with axis hole 8 mutually by fulcrum 6, be with spring 5 on the fulcrum 6, the two ends of this spring 5 are provided with outer adjutage 9 and interior adjutage 10, outer adjutage 9 acts on housing 1, and interior adjutage 10 acts on handle 7, and these handle 7 leading sections are provided with the chuck 11 of hook-type, and housing 1 front end face has the groove 12 that matches with chuck 11, when plug did not use, chuck 11 buckled in the plug groove 12 because spring 5 acts on.

As shown in Figure 4 and Figure 5, be respectively equipped with a hook-type groove 14 on 13 last two jack upper and lower positions of the utility model socket to outer process.

During use, finger cramping handle 7 end capacity compression faces, chuck 11 sticks up from plug groove 12, and inserted sheet 2 inserts receptacle sockets, and chuck 11 buckles into to loose one's grip in the socket groove 14 under spring 5 effects and gets final product simultaneously.Guaranteed that plug contacts with socket firmly, difficult drop-off can prevent that also plug from pulling out by mistake, and is safe and reliable.
