Abstract

The utility model relates to a terminal box for embedded pipes into the wall body, in particular to a terminal box embedded to the wall body in the electric installation engineering, which aims to solve the problems that the terminal box can not be led out of the wall properly and foreign bodies enter the pipe when the wire pipe is embedded in the axis position; the utility model is characterized in that a wedge-shaped through hole and the terminal box are connected to a whole, and the wedge-shaped through hole and the back section of the upper end for the terminal box are formed to an obtuse angle; the pipe end in the axis position is bent to an obtuse angle. The utility model has the advantages that the terminal box can be wired fast and conveniently, and the foreign bodies can be prevented to enter the pipe due to the wedge-shaped through hole with handle-knockout hole.

Description

The pre-buried effective terminal box of body of wall
Technical field
The utility model relates to a kind of terminal box that is fixed in body of wall of inlaying in electrical installation project.
Background technology
In the present stage electrical installation project, electric conduit is connected through locknut (claiming that again cup is crisp or end is female) transition with terminal box, and conduit must secretly bury in axial location when building wall.Conduit can go out the curved back of " Z " type by terminal box top and arrive axis, and this causes the box out of terminal box place excessive; Also can go out one the 90 curved back of degree and arrive axis, but this curved bending radius adds terminal box thickness by the terminal box rear portion, the distance considerably beyond the wall skin to axis, it is too much to cause terminal box to go out wall.This problem is quite thorny in real work.Simultaneously, with after terminal box is connected, the mouth of pipe also can cause conduit to fall into foreign matter as not specially shutoff to conduit through locknut, stops up conduit.
Summary of the invention
The purpose of this utility model is to provide a kind of body of wall pre-buried effective terminal box, and it can make electric conduit when axial location is pre-buried, and terminal box can appropriateness go out wall, and is again can box out not excessive; Not needing the shutoff operation just can hinder foreign matter enters in the conduit.
The technical scheme that its technical problem that solves the utility model adopts is: the tapered end that wedge shape leads directly to is in the top, terminal box rear portion or in terminal box top rearmost end, also an end has the straight-through gap end of gap to locate on terminal box top and outer engagement angle, rear portion, and the extended line that makes progress with the terminal box rear portion is acute angle---promptly link together in obtuse angle with the terminal box rear portion.The oval knock down hole that the band pull handle is arranged at the straight-through tapered end place of wedge shape; At the straight-through end that gap is arranged knock down hole corresponding with this gap and the band pull handle is arranged.When using, catheter end head is curved corresponding obtuse angle---promptly lead directly to and terminal box obtuse angle that the rear portion becomes, insert to lead directly to and just can.At this moment, the distance at the conduit of axial location and terminal box rear portion is the shortest, thereby makes conduit when axial location is pre-buried, and terminal box can appropriateness go out wall, also just problem that box out is excessive can not occur.Simultaneously, the knock down hole of band pull handle plays the effect of the shutoff mouth of pipe, can remove easily again when wearing electric wire.
The beneficial effects of the utility model are: terminal box and wedge shape is straight-through or the band gap is straight-through connects to one, and cost of manufacture is less than terminal box and the matching used price of locknut; The knock down hole at straightthrough port place can directly be protected conduit, has reduced one procedure; Conduit is when axial location, and the termination curves the obtuse angle, can be easy to link to each other with straight-through, and terminal box can appropriateness go out wall again, and its work is easy, the production efficiency height; During the conduit threading in pipe, the resistance at the obtuse angle that catheter end head curves can improve the effect of next procedure again less than the resistance that curves an angle of 90 degrees.
Description of drawings
Figure of description is the utility model profile.
1 conduit among the figure, 2 wedge shapes are straight-through, 3 band pull handle knock down holes, 4 terminal boxes, 5 and band pull handle knock down holes corresponding with the straight-through gap end of band gap, 6 band gap are straight-through.
Embodiment
Now describe the concrete structure of the pre-buried effective terminal box of the utility model body of wall in detail in conjunction with Figure of description.
Among the utility model Fig. 1, the tapered end of wedge shape straight-through [2] is acute angle in the top, terminal box [4] rear portion with the extended line that terminal box [4] rear portion makes progress---promptly fuse in obtuse angle with the terminal box rear portion.
Among the utility model Fig. 2, the extended line that the tapered end of wedge shape straight-through [2] makes progress at terminal box [4] top rearmost end and terminal box [4] rear portion is acute angle---promptly fuse in obtuse angle with the terminal box rear portion.
Among the utility model Fig. 3, an end has the gap end of straight-through [6] of gap to be acute angle on terminal box [4] top and place, outer engagement angle, rear portion with the extended line that terminal box [4] rear portion makes progress---promptly connect to one in obtuse angle with terminal box [4] rear portion.
In Fig. 1, Fig. 2, the tapered end of wedge shape straight-through [2] has the oval knock down hole [3] of band pull handle; In Fig. 3, the gap end of straight-through [6] of band gap has knock down hole [5] corresponding with this gap and the band pull handle.
Wedge shape straight-through [2] or band gap straight-through [6] and the angle that extended line is that terminal box [4] rear portion makes progress are good with the 30-60 degree, promptly are the 150-120 degree with terminal box [4] rear portion, are the best with 45 degree especially, promptly are 135 degree angles with terminal box [4] rear portion.
Wedge shape straight-through [2] or band gap straight-through [6] both can be injection molded into one with terminal box [4], also can produce separately after bonding or welding or other technology connect to one.

Claims (4)

1. pre-buried effective terminal box of body of wall, constitute by terminal box [4] and wedge shape straight-through [2] or band gap straight-through [6], it is characterized in that: the tapered end of wedge shape straight-through [2] is in the top, terminal box [4] rear portion or in terminal box [4] top rearmost end, also an end has the gap end of straight-through [6] of gap to locate on terminal box [4] top and outer engagement angle, rear portion, and the extended line that makes progress with terminal box [4] rear portion is acute angle---promptly link together in obtuse angle with terminal box [4] rear portion.
