Description
Technical field
Survival equipment field is the utility model is related to, more particularly to a kind of pipe for escaping.
Background technology
It is people-oriented, it is necessary to enough ventilation equipment, warning facility and means of escape during tunnelling.Its
The effect of middle pipe for escaping is when surprisingly occurring, for example preliminary bracing caves in, and worker can enter pipeline and escape, usually pipe
Headlamp and food can be equipped with road.
Traditional pipe for escaping uses steel pipe so that and whole pipe for escaping weight is big, and the connection between pipeline is time-consuming and laborious,
Steel pipe easily deforms under load impacting at the same time.With the development of material science, there are new plastic pipe intensity, tough performance to meet
It is required that while lightweight feature it is notable, correspondingly, the Combination Design of pipe for escaping is also required to improve.
Utility model content
Pipe for escaping quick, that resistance to pressure is strong is assembled the purpose of this utility model is to provide a kind of.
Technical solution adopted in the utility model is：
A kind of pipe for escaping, includes the tube body of some head and the tail connection, and each tube body is high molecular polythene material, each tube body
One end be the first bending part of radially evagination, the other end of each tube body is the second bending part of radially indent, and first is curved
Folding part can the second bending part of anchor ear, there is cavity between the first bending part and the second bending part, pressure-bearing pipe is equipped with each cavity,
Some bolt groups for running through the first bending part, pressure-bearing pipe and the second bending part are equipped between adjacent two tube body.
As the improvement of such scheme, each tube body is uniformly provided with three notches at the circumference of the first bending part, and three lack
Mouthful using the end face of tube body as starting point and in axial direction to extend the first bending part be three valves.
As the improvement of such scheme, the cross section of each pressure-bearing pipe is annulus, and each pressure-bearing pipe is stainless steel.
As the improvement of such scheme, each bolt group is from incline direction through the first bending part, pressure-bearing pipe and the second bending
Portion.
As the improvement of such scheme, set between pressure-bearing pipe and the first bending part and between pressure-bearing pipe and the second bending part
There is gasket.
As the improvement of such scheme, the wing of circular ring shape is equipped with the outside of each first bending part and each second bending part
Side.
The beneficial effects of the utility model：This pipe for escaping is outwards inside respectively due to the first bending part and the second bending part
After bending, cavity is formd between the two, after the cavity inserts pressure-bearing pipe, can prevent two tube body axial slips naturally, should
It is simple in structure, it is easy to assembly；When tube body receives impact, pressure-bearing pipe avoids tube body from deforming in bearing most pressure；Beat
If the bolt stem group entered is used for the bonding strength for further enhancing adjacent tubes.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the front sectional view of tube body；
Fig. 2 is the sectional view of two tube body junctions；
Fig. 3 is the side view of the first bending part.
Embodiment
With reference to Fig. 1~Fig. 3, the utility model is a kind of pipe for escaping, includes the tube body 1 of some head and the tail connection, each tube body 1
It is high molecular polythene material.One end of each tube body 1 is the first bending part 2 of radially evagination, can regard bell end as；Respectively
The other end of tube body 1 is the second bending part 3 of radially indent, can regard insertion end as.Each first bending part 2 and each second curved
The outside of folding part 3 is equipped with the wing side of circular ring shape, you can with regard each first bending part 2 as and each second bending part 3 be by
The position of two close end is raised or sunken.First bending part 2 can the second bending part of anchor ear 3, at this time the first bending part 2 wing side
The outer wall of tube body 1 is bonded, the inner wall of the wing side fitting tube body 1 of the second bending part 3, wing side has after being bonded 1 outer wall of tube body or inner wall
There is the effect of sealing waterproof.When 3 face of the first bending part 2 and the second bending part, between the first bending part 2 and the second bending part 3
The cavity of circular ring shape is formed, pressure-bearing pipe 5 is equipped with each cavity, is equipped between adjacent two tube body 1 and some runs through the first bending part
2nd, the bolt group 6 of 5 and second bending part 3 of pressure-bearing pipe.
After the cavity inserts pressure-bearing pipe 5, two tube bodies, 1 axial slip can be prevented naturally, this is simple in structure, assembling side
Just；When tube body 1 receives impact, pressure-bearing pipe 5 is used to bear most pressure, avoids tube body 1 from deforming；If the bolt stem squeezed into
Group 6 is used for the bonding strength for further enhancing adjacent tubes 1.
As preferred embodiment, each tube body 1 is uniformly provided with three notches 4 at the circumference of the first bending part 2, three
Notch 4 is using the end face of tube body 1 as starting point and in axial direction extends that to divide the first bending part 2 be three valves.On the basis of Fig. 1, lack
The length of mouth 4 is slightly longer than the length of the first bending part 2.In use, due to each first bending part, 2 elastically deformable
Ground opens, and reduces the difficulty of the second bending part 3 insertion；Utilize the elastic deformation at the same time, the first bending part 2 can preferably anchor ear
Second bending part 3, will not produce positioning.
As preferred embodiment, the cross section of each pressure-bearing pipe 5 is annulus, and each pressure-bearing pipe 5 is stainless steel.Each bolt
Group 6 is from incline direction through the first bending part 2,5 and second bending part 3 of pressure-bearing pipe so that each bolt group 6 can at the same time radially and
Axial direction produces pretightning force.
As preferred embodiment, between 5 and first bending part 2 of pressure-bearing pipe and 5 and second bending part 3 of pressure-bearing pipe it
Between be equipped with gasket, further enhance sealing effect.
When in use, first pressure-bearing pipe 5 is placed around the second bending part 3 and installed, then strut the first bending part 2, finally
Second bending part 3 and pressure-bearing pipe 5 are inserted into the first bending part 2 together, finally drill and squeeze into installation bolt group 6.
Certainly, the design creates and is not limited to the above embodiment, and the combination of the various embodiments described above different characteristic, also may be used
To reach good effect.Those skilled in the art can also make on the premise of without prejudice to the utility model spirit
With deformation or replace, these equivalent modifications or replacement are all contained in the application claim limited range.
