Abstract
The utility model discloses a pipe connecting assembly. The pipe connecting assembly comprises a pipe (1), a pipe fitting (2), a fastener (3), a locking ring (4) and a sealing ring (5). The pipe connecting assembly is characterized in that the pipe (1) is inserted into the pipe fitting (2), the pipe (1) is sleeved with the fastener (3), the rubber ring (5) is arranged between the pipe (1) and the pipe fitting (2), the pipe (1) is sleeved with the rubber ring (5), the locking ring (4) is arranged between the fastener (3) and the rubber ring (5), the face, making contact with the rubber ring (5), of the locking ring (4) is inclined, the locking ring (4) is downwards pressed by the fastener (3), and the locking ring (4) carries out tight clamping on the rubber ring (5) in the radial direction to achieve fastening and sealing. The pipe connecting assembly cannot loosen, and cannot cause water leakage.
Description
Technical field
The utility model relates to a kind of bindiny mechanism of pipeline, particularly relates to a kind of connection assembly for pipes.
Background technique
In prior art, the traditional connecting means of plastics indoor drainage pipe is except gluing, also have some materials can't stick with glue agent and connect (as polypropylene etc.), what the most often adopt is exactly that seal with elastometic washer connects, the tradition connecting means is that while screwing with fastening piece, downward pressure makes " O type " rubber ring produce distortion, produces extruding force tubing is embraced and realized locking.Problem is that after pipeline is subject to the current vibrations, rubber ring can produce bounce-back, makes fastening piece loosening, causes and leaks.
The model utility content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of fastening piece can not become flexible, and can not cause the connection assembly for pipes leaked.
The technical solution of the utility model is: connection assembly for pipes, comprise tubing 1, pipe fitting 2, fastening piece 3, locking ring 4, seal ring 5, it is characterized in that: described tubing 1 inserts in described pipe fitting 2, described fastening piece 3 is enclosed within tubing 1 outside, be provided with rubber ring 5 between described tubing 1 and pipe fitting 2, rubber ring 5 is enclosed within the outside of described tubing 1, described locking ring 4 is placed between fastening piece 3 and rubber ring 5, described locking ring 4 is skewed with the face that described rubber ring 5 contacts, and fastening piece 3 presses down locking ring 4, locking ring 4 radially tightens rubber ring 5 to realize fastening and sealing.
Further, the gap between the shape of the cross section of described rubber ring 5 and described tubing 1, pipe fitting 2, locking ring 4 threes is complementary.
Further, described tubing 1, pipe fitting 2, fastening piece 3 and locking ring 4 are polypropylene material.
The utility model beneficial effect is: this connection assembly for pipes reasonable in design, changed tradition and rubber ring has been flattened vertically to the mode of locking, designed the fastener combination of new structure, the mating face of locking ring 4 and rubber ring 5 is inclined-plane, when fastening piece 3 is screwed down, the inclined-plane of locking ring 4 produces radial force and directly rubber ring 5 is pressed to tubing 1, rubber ring 5 produces thrust tubing 1 is held tightly, its maximum advantage is that the rebounding force of rubber ring 5 is radially, can be because pipe vibration makes fastening piece 3 loosening, therefore connect very reliable, not being afraid of the situation of leaking occurs, very practical.
The accompanying drawing explanation
Fig. 1 is the interconnective cross-sectional view of the utility model connection assembly for pipes;
Accompanying drawing indicates: 1 is that tubing, 2 is that pipe fitting, 3 is that fastening piece, 4 is that locking ring, 5 is seal ring
Embodiment
Below in conjunction with accompanying drawing, preferred implementation of the present utility model is elaborated.
Embodiment:
As shown in Figure 1, connection assembly for pipes, comprise tubing 1, pipe fitting 2, fastening piece 3, locking ring 4, seal ring 5, it is characterized in that: described tubing 1 inserts in described pipe fitting 2, described fastening piece 3 is enclosed within tubing 1 outside, be provided with rubber ring 5 between described tubing 1 and pipe fitting 2, rubber ring 5 is enclosed within the outside of described tubing 1, described locking ring 4 is placed between fastening piece 3 and rubber ring 5, described locking ring 4 is skewed with the face that described rubber ring 5 contacts, and fastening piece 3 presses down locking ring 4, locking ring 4 radially tightens rubber ring 5 to realize fastening and sealing.
Further, the gap between the shape of the cross section of described rubber ring 5 and described tubing 1, pipe fitting 2, locking ring 4 threes is complementary.
Further, described tubing 1, pipe fitting 2, fastening piece 3 and locking ring 4 are polypropylene material.
Finally it should be noted that; the foregoing is only preferred embodiment of the present utility model; rather than, to the restriction of technical solutions of the utility model, any being equal to that the utility model technical characteristics is done, replace or corresponding improvement, still within protection domain of the present utility model.
Claims (3)
