Abstract

The utility model relates to a toothless rapid joint of a connection box. The toothless rapid joint of a connection box is characterized in that a connection box and a slot pipe are connected through a transfer joint provided with a plurality of elastic built-in sheets; the elastic built-in sheets are directly inserted into circular holes on the connection box, and the built-in purpose can be achieved. Simultaneously, the outer edge end of the built-in sheets is sheathed with a water-proof washer; when the transfer joint is inserted into the circular hole, the water-proof washer is supported and fixed through a ring flange on the transfer joint and tightly abutted with the connection box. The toothless rapid joint of a connection box has the advantages of water proofing and rapid and easy installation.

Description

Toothless rapid joint of connection box

The utility model relates to the snap joint of a kind of wire casing terminal box anodontia, belongs to building materials field.

Terminal box is connected with the wire casing pipe, adopts the bolt lock tube usually, bothers again during operating cost.The wire casing pipe just must give earlier before the can concrete and burying underground, for preventing that concrete from entering in the pipe, generally to repave concrete behind the screw locking mouth of pipe, therefore must cause moisture content to infiltrate the mouth of pipe, it is stuck that thread is got rusty, and manufacturing cost is also high, still needs at the mouth of pipe after the wire casing pipe is made--tapping, time-consuming taking a lot of work.

It is a kind of not only waterproof and installing more fast and convenient quick coupling structure that the utility model provides.

For reaching fast and the purpose of waterproof, design a cylindric adapter coupling, the wire casing pipe directly adheres to the rear end of this adapter coupling, the adapter coupling front portion is provided with plurality of elastic build-in sheet, and when the circular hole on the adapter coupling insertion terminal box, the elastic embedding sheet inwardly shrinks, after entering circular hole, the build-in sheet withstands the terminal box inwall because of elastic stretch, reaches fixing purpose.On adapter coupling, put a waterproof washer, promptly waterproof infiltration.

The utility model has the advantages that:

1. it is quite convenient to install, and only needs adapter coupling is directly embedded in the terminal box and can finish, and need not impose rotation.

2. adapter coupling of the present utility model and wire casing pipe are not with bolt, so unlikely generation cost improves and can engage more fast, practicality is good.

3. the special build-in sheet on the adapter coupling, because of having the elastic reaction of outside extension, therefore closely build-in on terminal box, and utilize the ring chimb that joint itself has and overlap solid its waterproof washer, waterproof washer system cover is fixed in the outer rim of build-in sheet, and is close to the ring chimb, therefore behind the adapter coupling build-in, get final product the packing waterproof washer, reach the waterproof purpose.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model three-dimensional exploded view.

Fig. 2 is the utility model three-dimensional combination figure.

Fig. 3, Fig. 4 are the utility model assembled sectional views.

Referring to Fig. 1, Fig. 2, the utility model comprises terminal box 2, one waterproof washers, 3, one adapter couplings 8 and a wire casing pipe 7.Terminal box 2 box bodys be provided with circular hole 1 in case with adapter coupling 8 sockets.Adapter coupling 8 is a hollow cylinder, and its middle part has a ring chimb 5, and front end is provided with some

Type elastic embedding sheet 4.Elastic embedding sheet 4 front ends are italic 6 design, when entering circular hole 1 with each build-in sheet 4 of box lunch, utilize the italic 6 of build-in sheet 4 front ends and build-in sheet 4 is inwardly folded, and are convenient to interlocking.When adapter coupling 8 embedded the circular hole 1 of terminal box 2, build-in sheet 4 entered in the box and the elastic reaction that has because of itself is outwards upheld, and holds out against the box wall and reaches the build-in purpose.Waterproof washer 3 is sheathed on build-in sheet 4 outer rims and is close to ring chimb 5 front ends, and its waterproof washer 3 of packing when adapter coupling 8 embeds terminal box 2 reaches the waterproof purpose.

Referring to Fig. 3, Fig. 4, during the construction distribution, need only earlier wire casing pipe 7 directly be adhered to adapter coupling 8 rear ends, again waterproof washer 3 is placed on build-in sheet 4 outer edges, can finish quick socket in the circular hole 1 that directly adapter coupling 8 is inserted on the terminal box 2 immediately.

Claims
