Description

A kind of pipe bender

Technical field

The utility model relates to a kind of construction equipment, particularly a kind of pipe bender.

Background technology

In engineering construction, often need to use pvc pipe, and in use often need pvc pipe be embedded in the wall, with prevent pvc pipe expose outside wall, cause not attractive in appearance.

And when being embedded in pvc pipe in the wall, also need bending be carried out in the end of pvc pipe, so that place the circuit in the pvc pipe to derive; But when laying pvc pipe, normally earlier pvc pipe is embedded in the floor, and the end of pvc pipe only sub-fraction be exposed on the face of floor or the bottom of cement beam; Need that the constructor is free-hand to carry out so will bending be carried out in its end; The inconvenient constructor's application of force in the position that the back pvc pipe is exposed owing to lay bricks, thus the very big strength of constructor will be spent, and also crooked effect is not good enough yet; Even limit to for fear of the place sometimes; Can't construct, and this situation not merely appears in the use of pvc pipe, a lot of pipelines also the problems referred to above can occur at all.

The utility model content

The utility model purpose is to provide a kind of pipe bender of convenient construction person crooked pipeline, makes the bend pipe process not receive place restriction, simpler, quick and laborsaving.

Above-mentioned pipe bender is used for crooked pipeline, comprises pipe box and handle, and handle and sleeve pipe ramp interface are provided with through hole in the said pipe box, and through hole is used for socket-connecting with pipeline.

Adopt this pipe bender as long as pipe box and pvc pipe are nested, and handle up spurred just accomplish the bend pipe operation, owing to handle and sleeve pipe are the ramp interface convenient construction person application of force, so whole process is simple, quick and laborsaving.

Preferably, the angle between said handle and sleeve pipe is the 40-50 degree.

Preferably, for removably connecting, the internal diameter size of through hole is complementary with the external diameter size of pipeline between said pipe box and handle.

Because the caliber of pipeline has various specification, so adopt such scheme to make pipe bender can change different pipe boxes, match use with the pipeline of this and different size, the applicability of pipe bender is increased greatly.

Preferably, said pipe box outer wall is provided with and is used for the connecting portion that joins with handle, connecting portion and pipe box outer wall ramp interface, and handle is pegged graft with connecting portion or bolt is connected.

Preferably, comprise that also one is used to insert the spring in the pipeline.

Fracture easily or jackknifing during pipe bending, thus in pipeline, insert spring, spring in the pipeline to the pipeline application of force, thereby make inside and outside the pipeline stressed evenly, make pipeline when bending, be not easy to fracture or jackknifing.

Preferably, the length of said handle is 25-30 centimetre.

If being carried out curved major, pipeline utilize lever principle handle to be carried out the application of force and the effect reached; Handle is long then to make pipe bender become burdensome and use inconvenience; So the too short then inconvenient constructor's application of force of handle is the 25-30 centimetre of desirable length range that is handle.

Preferably, the length of said through hole is 3-5 centimetre, and the internal diameter of through hole is than the big 2-5 millimeter of external diameter of pipeline.

Because through hole is used for and the pipeline socket, and pipeline needs crooked part shorter, so through hole is unsuitable long, is desirable length range so the length of through hole is 3-5 centimetre; And the wide 2-5 millimeter of the wide external diameter than pipeline in the footpath of through hole has made things convenient for through hole and pipeline to socket-connect, and has guaranteed that through hole and pipeline socket are firm.

The specific embodiment

First kind of embodiment of the utility model comprises handle 2, pipe box 1 and spring 3 like Fig. 1, shown in 2 and 9,25 centimetres of handle 2 length; And handle 2 and pipe box 1 ramp interface, 1 of handle 2 and sleeve pipe are opened has an angle, and the angle angle is 45 degree; To handle 2 application of forces, be provided with the through hole 11 that is communicated with pipe box 1 with this convenient construction person in the said pipe box 1, through hole 11 is used for socket-connecting with pvc pipe 4; The aperture of said through hole 11 is set according to the pvc pipe 4 of different size; And the external diameter of pvc pipe 4 is generally 20 millimeters, 25 millimeters and 32 millimeters, so the aperture of pipe bender through hole 11 is made as 23 millimeters, 28 millimeters and 35 millimeters usually, has made things convenient for through hole 11 and pipeline 1 to socket-connect; And guaranteed that through hole 11 and pvc pipe 4 sockets are firm; Because pvc pipe 4 needs crooked part shorter, so through hole 11 is unsuitable long, thereby the length of present embodiment through hole 11 is 5 centimetres.

As shown in Figure 9, when first kind of embodiment uses, overlap the outer wall of steady pvc pipe 4 earlier with pipe box 1; And spring 3 is inserted in the pvc pipe 4, spring 3 in the pvc pipe 4 to pvc pipe 4 application of forces, thereby make inside and outside the pvc pipe 4 stressed evenly; Make pvc pipe 4 when bending, be not easy to fracture or jackknifing, the constructor is as long as pulling handle 2 just can be with pvc pipe 4 bendings then, and whole process is simple, quick and laborsaving; Wherein A is a fragment of brick, and B is the signal direction of user's application of force.

Second kind of embodiment of the utility model is shown in Fig. 3 to 5, and the difference of first kind of embodiment is 2 on said pipe box 1 and handle for removably connecting, and pipe box 1 outer wall is provided with connecting portion 14; Connecting portion 14 and pipe box 1 outer wall ramp interface, connecting portion 14 is provided with screw 12, and handle 2 ends are provided with bolt 21; Screw 12 joins with bolt 21, pipe box 1 and handle 2 is connected as a single entity, because pipe box 1 can separate with handle 2; So same handle 2 is supporting a plurality of different pipe boxes 1 simultaneously; The aperture of second kind of embodiment is supporting 1,3 pipe box 1 through hole 11 of 3 pipe boxes has nothing in common with each other, and is respectively 23 millimeters, 28 millimeters and 35 millimeters.

The method for using of second kind of embodiment is consistent with first kind of embodiment; Its difference is and need selects different pipe boxes 1 according to the caliber of pvc pipe 4; Then pipe box 1 and handle 2 are joined; Adopt second kind of embodiment to make pipe bender can change different pipe box 1, use, the applicability of pipe bender is increased greatly with pvc pipe 4 pairings of this and different size.

The third embodiment of the utility model is shown in Fig. 6 to 8; And the difference of second kind of embodiment is that connecting portion 14 is provided with groove 13 in order to removably connect for said

pipe box

1 and 2 on handle, and handle 2 ends are provided with projection 22; Groove 13 plugs with projection 22, and pipe box 1 and handle 2 are connected as a single entity.

The method for using of the third embodiment is consistent with two kinds of embodiment, and its difference is that

pipe box

1 and 2 on handle are to peg graft, and makes the replacing of pipe box 1 more convenient.

The improved protection domain that also is regarded as patent on the basis of above embodiment.
