Relatively low polyethylene outer protective pipe.
Specific technical solution is as follows：A kind of polyethylene outer protective pipe, including the first tube body, the second tube body, connection ring and fixation
Part, connection ring include inner and outer wall, and inner wall is shiny surface, and outer wall is cambered surface, and outer wall is equipped with stopper protrusion, limit convex position
Among outer wall, first tube body and the second tube body are arranged on connection ring both ends, and the first tube body and the second tube body are structure phase
Same pipe fitting, pipe fitting one end have enlarged portion, and enlarged portion is bonded with the outer wall, and the fixing piece includes locating ring and locking group
Part, locating ring have notch section, and notch section both sides are equipped with mounting portion, and the latch assembly is arranged on mounting portion, position ring set
It is located at the outside of tube body enlarged portion.
It is the attached technical scheme of the utility model below.
Preferably, the enlarged portion of first, second tube body is located at stopper protrusion both sides.
Preferably, the enlarged portion is arc, and the connection ring is arc.
Preferably, the latch assembly includes screw bolt and nut, and the mounting portion has through-hole, and bolt is threaded through
In through-hole, nut is arranged on bolt.
Preferably, two mounting portions are arranged on notch section both sides.
The technique effect of the utility model：A kind of polyethylene outer protective pipe of the utility model can be realized in junction
Portion's channel is more smooth, reduces the obstruction to fluid, the smoothness of lifting fluid flowing；It in addition, can according to the connection of different pipe fittings

Description of the drawings
Fig. 1 is the schematic diagram of the polyethylene outer protective pipe of the utility model embodiment.
Fig. 2 is the exploded view of the polyethylene outer protective pipe of the utility model embodiment.
Fig. 3 is the sectional view of the polyethylene outer protective pipe of the utility model embodiment.
Specific embodiment
In the following, the substantive distinguishing features and advantage of the utility model are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figure 1 to Figure 3, a kind of polyethylene outer protective pipe of the present embodiment includes the first tube body 1, the second tube body 2, connection
Ring 3 and fixing piece 4, connection ring 3 include inner wall 31 and outer wall 32, and inner wall 31 is shiny surface, and outer wall 32 is cambered surface.It is set on outer wall 32
There is stopper protrusion 33, stopper protrusion 33 is located among outer wall.First tube body, 1 and second tube body 2 is arranged on 3 liang of connection ring
End, the first tube body and the second tube body pipe fitting identical for structure, pipe fitting one end have enlarged portion 5, enlarged portion and the outer wall 32
Fitting.The fixing piece 4 includes locating ring 41 and latch assembly 42, and locating ring 41 has notch section 44, and notch section both sides are equipped with
Mounting portion 43.The latch assembly 42 is arranged on mounting portion, and locating ring is set in the outside of tube body enlarged portion 5.Above-mentioned technology
In scheme, it is connect by first, second tube body with connection ring both ends so that by internal wall transitions between two tube bodies, so as to make pipe
Inner passage is smoother after body connection so that fluid flowing is more smooth.Connection ring can customize both ends according to the caliber of two tube bodies
Size is different, and inner wall is tilts shiny surface so that fluid stream is out-of-date, by inner wall water conservancy diversion, meanwhile, connection ring customize cost compared with
It is low, reduce cost.In addition, it will quickly can be positioned between tube body and connection ring by fixing piece.
In the present embodiment, the enlarged portion 5 of first, second tube body is located at 33 both sides of stopper protrusion, and stopper protrusion can be to expansion
The position in portion is limited.
In the present embodiment, the enlarged portion is arc, and the connection ring is arc, so as to which enlarged portion be made more to be pasted with connection ring
It closes, enhances the leakproofness of connection.
In the present embodiment, the latch assembly 42 includes bolt 421 and nut 422, and the mounting portion has through-hole, bolt
421 wear in through-holes, and nut 422 is arranged on bolt.By the fastening of bolts and nuts, locating ring can be tightened, from
And connection ring and enlarged portion are positioned.
In the present embodiment, two mounting portions 43 are arranged on notch section both sides, consequently facilitating locating ring is shunk or expansion.
A kind of polyethylene outer protective pipe of the present embodiment can be realized more smooth in the inner passage of junction, reduce to fluid
Obstruction, lifting fluid flowing smoothness；In addition, various sizes of connection ring may customize according to the connection of different pipe fittings, into
This is relatively low, and positioning is convenient.
It should be pointed out that above-mentioned preferred embodiment is only to illustrate the technical concepts and features of the utility model, purpose
It is the content for allowing person skilled in the art that can understand the utility model and implements according to this, can not this reality be limited with this
