Abstract
The utility model relates to a double-buckle threaded connection structure of a polypropylene mute drain pipe. The double-buckle threaded connection structure comprises a pipe, a through pipe fitting and a locking apparatus, wherein the internal diameter of the through pipe fitting is matched with the external diameter of the pipe; the locking apparatus comprises a locking cover, an upper buckle ring, a lower buckle ring and a rubber ring; the upper buckle ring, the lower buckle ring and a seal ring are sleeved on the pipe; the seal ring is arranged between the lower buckle ring and the through pipe fitting; the lower buckle ring is provided with a clamping block matched with the inner wall of the locking cover; The upper buckle ring and the lower buckle ring are matched in size; the two ends of the through pipe fitting are provided with external threads; and the locking cover is provided with internal threads matched with the external threads. The double-buckle threaded connection structure of the polypropylene mute drain pipe has the advantages of good airtightness, easiness for disassembly, convenience in installation, high connection strength, environmental friendliness and no gluewater pollution.
Description
Technical field:
The utility model relates to two seizing type screw connection structures of the quiet waste pipe of a kind of polypropylene, also is applicable to some other tubing and pipe fitting simultaneously.
Background technique:
In daily life, the use of waste pipe more and more widely.The Placement of waste pipe generally has traditional bayonet joint mode, electric smelting or hot melt Placement, common rubber band to be threaded etc.Traditional bayonet joint mode needs earlier to carry out ground to the tubing termination in assembly process handles and carries out socket joint again, operate cumbersomely, and in high-lift operation, is difficult for socket joint, and not quick detachable refitting processing; Electric smelting or hot melt Placement are not suitable for the polypropylene waste pipe; Common rubber band is threaded and can solves the above problems, but its sealing is superior inadequately.
The utility model is an a kind of pair of seizing type screw connection structure, and pipe keeps motionless when installation and removal, has good airproof performance, and is quick detachable, easy for installation, and join strength is high, and environmental protection does not have glue and pollutes.And the join strength of traditional Placement and sealability are well below the utility model.The utility model bears the bear pressure of pressure greater than structure in the industry standard aspect bearing hydraulic pressure.
The model utility content:
The technical problem that the utility model solved is to provide two seizing type thread connecting modes of the quiet waste pipe of polypropylene of a kind of environmental protection, good sealing effect.
The purpose of the utility model is exactly to strengthen the join strength and the environmental-protecting performance of quiet drainage pipe of polypropylene and pipe fitting, has proposed a kind of two fixedly connecting means of the quiet waste pipe of polypropylene of seizing type structure that are threaded.
The utility model technology provides two seizing type screw connection structures of the quiet waste pipe of a kind of polypropylene; Comprise tubing, straight-through pipe fitting and locking device, the internal diameter of straight-through pipe fitting and the external diameter of tubing are complementary, and described locking device comprises tightening cover, last snap collar, following snap collar and rubber band; Last snap collar, following snap collar and ring set are on tubing; Seal ring is located at down between snap collar and the straight-through pipe fitting, and described snap collar down is provided with the fixture block that cooperates with the tightening cover inwall, described snap collar and the following snap collar size coupling of going up; Described straight-through pipe fitting two ends have outside thread, have the internal thread that is complementary with above-mentioned outside thread on the tightening cover.。
The linkage structure of the utility model can adopt following method assembling and get:
The quiet tubing of polypropylene is filled in locking device and straight-through main pipe body endoporus, with the mode that is threaded tightening cover is connected with straight-through main pipe body, the tightening cover screw thread is screwed, and last snap collar, following snap collar and rubber band will be locked tubing.Yet play the interconnect function of environmental protection and good sealing effect.
Two seizing type screw connection structure good airproof performances of the quiet waste pipe of polypropylene of the utility model, quick detachable, easy for installation, join strength is high, and environmental protection does not have glue and pollutes.
The quiet waste pipe of polypropylene is when carrying out piping erection; The two seizing type screw connection structures of pipe material by adopting can absorb certain thermal expansion of pipeline, and the quiet waste pipe of polypropylene guarantees the sealing and the stretchability of pipeline with straight-through pipe fitting, rubber band; Need not to use glue; Easy to assemble, do not receive the restriction of installation environment, mounting cost is low; Water-stop property and self-regulation are good, need not use slip joint, satisfy the deformation requirements of expanding with heat and contract with cold, and noise plays certain noise reduction to next pipe fitting transmission in the time of can avoiding the water impact tube wall again.
Description of drawings
Fig. 1 is the structural representation of two seizing type screw connection structures of the quiet waste pipe of the utility model polypropylene.
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the technological scheme of the utility model is described further, but the mode of execution of the utility model is not limited thereto.
With reference to Fig. 1, two seizing type screw connection structures of the quiet waste pipe of polypropylene comprise tubing 1, straight-through pipe fitting 2 and locking device; The internal diameter of straight-through pipe fitting 2 and the external diameter of tubing 1 mate each other; Said locking device comprises tightening cover 3, last snap collar 4, snap collar 5 and seal ring 6 down, and last snap collar 4, time snap collar 5 and seal ring 6 are set on the tubing 1; Seal ring 6 is located at down between snap collar 5 and the straight-through pipe fitting 2, and last snap collar 4 is provided with the fixture block 7 that cooperates with tightening cover 3 inwalls; Straight-through pipe fitting 2 two ends have outside thread, have the internal thread that cooperates with above-mentioned outside thread on the tightening cover 3.
The quiet straight-through pipe fitting body design of polypropylene becomes screw thread, and quiet tubing is filled in tightening cover, last snap collar, following snap collar and seal ring, then tightening cover and straight-through main pipe body is connected as one.
Compare with other Placements, this novel practical technology is advantage once:
1, strengthened join strength.
2, environmental protection more connects when PVC-U installs and adopts glue to connect.There is harm in glue to human body and environment.
3, make things convenient for the product installation and maintenance.
4, each parts can be accomplished interchangeability, when the pipe fitting damage takes place under installation or other situation, can the part replacement of damaging be accomplished property more economically.
Claims (4)
1. two seizing type screw connection structures of the quiet waste pipe of polypropylene is characterized in that: it comprises tubing, straight-through pipe fitting and locking device, and the internal diameter of straight-through pipe fitting and the external diameter of tubing are complementary; Locking device comprises tightening cover, last snap collar, following snap collar and seal ring, and last snap collar, following snap collar and ring set are on tubing, and seal ring is located at down between snap collar and the straight-through pipe fitting.
