Description

A kind of telescopic socket

Technical field

The utility model belongs to Mechanical course field, a kind of specific socket with Telescopic.

Background technology

Current flexible socket, is mainly fixed in wall, than being to rely on spring if any one kind, can press whenever necessary Switch, socket can eject, it is not necessary to when can then be pushed into, socket is re-closed in wall, but utilizes spring to eject, and is needed The frictional resistance in the elastic force and telescopic process of spring is considered, and spring can reach it after long-time use Fatigue limit, then influence the telescopic effect of socket, it is after a long time use, internal just as automatic folding umbrella The ejection effect of spring is just good not as before.Also one kind be built-in wall can extending wire, by rotating rotary insertion Hole, can pull out the related electric wire of jack, and user can use in certain distance.Except the socket that these are fixed in wall, There is a kind of socket at present, jack above can avoid adjacent receptacle spacing is too small from causing plug not insert with transverse shifting, And the space occupied is constant.In addition to above-mentioned socket, also wifi sockets, regular socket, foldable socket etc., but it is simultaneously In the absence of Telescopic.

In the socket to have emerged at present, for the socket being fixed in wall, its telescopicing performance can actually reduce socket Space-consuming, it is convenient to bring, immovable (being fixed on wall) yet with jack body, such socket be more suitable for household, Used in office.For the people often to go on business, the problem of needing to mobile phone, computer charging is inevitably run into, and Train, the jack on hotel are limited at present, and it is inconvenient to carry the larger socket of volume.

The content of the invention

Technical problems to be solved

In order to avoid the shortcomings of the prior art, the present invention proposes a kind of novel retractable socket, the socket is cube Body shape, there is inside and outside double-layer structure, inner layer socket can be extracted out by way of stretching, be pushed into unwanted when, internal buckle Realization can be engaged to fix.Small volume, be easy to carry about with one, expansion internal layer jack can expand jack quantity, it is not necessary to when be pushed into, It is simple in construction, it is readily produced and promotes.

Technical scheme

A kind of telescopic socket, it is characterised in that including outer socket and inner layer socket, the one side of outer socket is opening , inner layer socket is embedded in outer socket by opening, is fixed with roller on the left and right sides of inner layer socket, is inserted in outer layer The inner surface that seat contacts with roller is provided with the sliding way and glide path being engaged with roller, in one end of sliding way and glide path Baffle plate provided with a projection limits inner layer socket extended position, and inner layer socket is stretched by slip of the roller on slideway to realize Contracting.

The direction of sliding way and glide path is opposite up and down.

Buckle head is additionally provided with the rear side of inner layer socket, is provided with outer socket inner surface corresponding with inner layer socket Snap seats, inner layer socket is during push-in is shunk, and buckle head and snap seats are engaged, so as to realize fixation.

Draw ring is provided with the one side of inner layer socket outwardly.

Beneficial effect

The utility model proposes a kind of can increase jack quantity by way of pulling out inner layer socket.With existing profit Compared with the flexible socket of spring ejection inner layer socket, buckle head and buckling seat structure the ratio spring structure of this socket are more steady Gu after buckle structure is mutually twisted, inner layer socket can be shunk in outer socket completely, and outer surface is in fair state. Meanwhile the economic benefits of buckle are better than spring, just right ejection effect is realized, it is necessary to the spring of specific stiffness factor. Buckle head and snap seats are easy to install, pull draw ring to depart from during use, while utilize roller and slideway, reduce telescopic process In frictional resistance, can more swimmingly pull out inner layer socket.

Embodiment

The utility model is further described in conjunction with embodiment, accompanying drawing：

As seen from Figure 1, telescopic socket has double-layer structure, is outer socket 7 and inner layer socket 1 respectively, inner layer socket 1 In the inside of outer socket 7, can be extracted out by way of stretching.Roller 5 is fixed with the surface of inner layer socket 1, shares four It is individual, should there are four slideways, respectively two sliding ways 9 and two glide paths 6 on the other hand, sliding way 9 and glide path 6 are fixed on The inner surface of outer socket 7, it is engaged with roller 5.Roller 5 is during inner layer socket 1 is extracted out in sliding way 9 and glide path Slided on 6.There are the baffle plate 4 of a projection, the mistake that roller 5 slides to the right in the right side tail portion of sliding way 9 and glide path 6 Cheng Zhonghui runs into baffle plate 4, and baffle plate 4 hinders roller 5 to continue to slide to the right, the limit now stretched out for inner layer socket 1.It is anti- Only at limit of stretch, possibility that inner layer socket 1 can topple and extract out, the direction of sliding way 9 and glide path 6 phase up and down Instead.Buckle head 3 is on the surface of inner layer socket 1, and snap seats 8 are on the inner surface of outer socket 7.Inner layer socket 1 is shrinking push-in (rolling Wheel 5 slides to the left) during, buckle head 3 and snap seats 8 can be engaged, so as to realize fixation.Draw ring 2 is in inner layer socket 1 Surface on, it is necessary to when pulling out, pull draw ring 2, buckle head 3 and snap seats 8 can depart from.

The course of work：When needing to stretch out inner layer socket 1, draw ring 2 can be pulled, now buckle head 3 and snap seats 8 can occur Depart from, roller 5 can slide to the right on sliding way 9 and glide path 6, stop sliding until running into the obstacle of baffle plate 4, now to be interior The extreme position that layer socket 1 pulls out.When end is in use, inner layer socket 1 can be promoted manually, roller 5 slides until buckle to the left First 3 and snap seats 8 be engaged, now inner layer socket 1 is pushed completely into, and outer surface is in fair state.
