The utility model discloses a kind of channel bend, comprise the bend pipe of 90 ° and the spool interface at bend pipe two ends, described spool interface is respectively external spool interface and built-in line tube interface, described external spool interface coaxially connects outward in one end mouth of pipe of bend pipe, the other end of bend pipe is set to straight tube and becomes built-in line tube interface, the bore of described built-in line tube interface is equal with the bore of external spool interface and be matched with the caliber of spool, and the described position of built-in line tube interface in bend pipe is no more than the axis of external spool interface.The utility model shortens the threading path of wire between bend pipe and spool interface, is convenient to wire walking in bend pipe.

Description

Channel bend

(1) technical field:

The utility model relates to field construction equipment, is specially a kind of channel bend.

(2) background technology:

In electrically and in the construction of automated system wiring work of industry and civil buildings, the normal object adopting the mode laying spool to reach protection cable, facilitate maintaining cables, keep building wall neat and artistic.

In Specific construction, such as cable need be arranged in each section of spool successively, for the turning of wiring, need adopt the connection that 90 ° of union elbows realize between two sections of straight tubes, and cable threading is the most unfeasible in construction in 90 ° of union elbows; Existing 90 ° of union elbows are passed through mutually by two straight vertical siphunculus to form, in threading process, cable in pipe is often blocked by ° bent angle of 90 in pipe, be difficult to light turnover, particularly thick line cable is to small diameter winding pipe threading, need are manually constantly bending, and cable could a section be walked by cable, and causing work progress loaded down with trivial details, is the major reason affecting construction period progress.

(3) utility model content:

For the deficiency that prior art exists, technical problem to be solved in the utility model proposes a kind of channel bend being easy to threading.

The channel bend that can solve the problems of the technologies described above, its technical scheme comprises the bend pipe of 90 ° and the spool interface at bend pipe two ends, described spool interface is respectively external spool interface and built-in line tube interface unlike the prior art, described external spool interface coaxially connects outward in one end mouth of pipe of bend pipe, and the other end of bend pipe is set to straight tube and becomes built-in line tube interface.

In said structure, by by one end spool interface retraction bend pipe, thus shorten the threading path of wire between bend pipe and spool interface and become more smooth and easy.

Conventionally, the bore of external spool interface be designed to equal with the bore of built-in line tube interface and be matched with the caliber of spool.

For retaining the radian of bend pipe necessity, the described position of built-in line tube interface in bend pipe is no more than the axis of external spool interface.

Advantage of the present utility model:

1, the utility model channel bend just can pass straight through elbow without bending wire, easy to use, and operating efficiency is high.

2, the utility model is applicable to various pipes elbow, as carried the channel bend of gas or liquid, being conducive to gas or the unimpeded mistake of liquid stream, preventing line clogging.

3, the utility model structure is simple, saves material, and cost reduces.

Fig. 1 is the structural representation of one embodiment of the present invention.

Fig. 2 is the structural representation of grafting spool in Fig. 1 execution mode.

Fig. 3 (a) is the structural representation of Fig. 1 execution mode formation three-way elbow.

Fig. 3 (b) is the structural representation of Fig. 1 execution mode formation four-way elbow.

Figure number identifies: 1, bend pipe; 2, external spool interface; 3, built-in line tube interface; 4, wire; 5, three-way elbow; 6, four-way elbow; 7, spool.

(5) embodiment:

Below in conjunction with accompanying drawing illustrated embodiment, technical scheme of the present invention is further described:

The main body of inventive pipeline elbow is the bend pipe 1 of 90 °, outside the top-right mouth of pipe of bend pipe 1, external spool interface 2 is set, described external spool interface 2 is coaxially connected with this mouth of pipe, the other end of bend pipe 1 lower left is set to straight tube and becomes built-in line tube interface 3, and the diameter of straight tube increases and becomes the bore of built-in line tube interface 3; The described bore of external spool interface 2 and the bore of built-in line tube interface 3 are set to equal and are matched with the caliber of spool 7, the degree of depth of external spool interface 2 and the degree of depth of built-in line tube interface 3 are set to identical, and the depth location of built-in line tube interface 3 is no more than the axis of external spool interface 2, as shown in Figure 1.

In said structure, wire 4 is walked in bend pipe 1 by built-in line tube interface 3 and external spool interface 2, because built-in line tube interface 3 is located in the mouth of pipe of bend pipe 1, shorten wire 4 and walk distance in bend pipe 1, make the threading of wire 4 much easier compared with traditional structure, even can pass straight through without bending wire 4, as shown in Figure 1.

After required wire 4 is walked, two ends spool 7 (wire 4 has been walked wherein) is plugged in respectively in external spool interface 2 and built-in line tube interface 3, as shown in Figure 2.

Channel bend as shown in Figure 1 is not only applicable to the cable wiring manufacture of cable, is also suitable for the construction and installation of water pipe, sewer, gas piping, pneumatic circuit, fluid pressure line.

Technical scheme of the present invention is not confined to the utilization of two logical elbows, applicable equally for three-way elbow 5, four-way elbow 6, as shown in Fig. 3 (a), Fig. 3 (b).
