Abstract

The utility model relates to a quick fastening seal water supply pipe joint, which is used in the building engineering. The quick fastening seal water supply pipe joint is composed of a pipe body, a cover body, a sealing rubber ring, a locking ring and a clamping lock. The sealing rubber ring is arranged on the bottom of the sealing table of the inner opening of the pipe body connecting end. The locking ring is arranged on the sealing rubber ring. The cover body is pressed and connected with the press end. The locking ring is a ring with an opening, and the inner of the ring body is provided with 3-15 locking cards. The utility model has the advantages of no connection pasting and welding, rapid connection, good sealing effect and 40-60 atmospheric pressure bearing, and is a substitute of the water supply pipe joint of the building engineering.

Description

Fastening seals Water supplying tube joint fast

The quick fastening sealing Water supplying tube joint that uses in a kind of construction engineering.

Delivery (pipe) line is the prerequisite water supply facilities of construction engineering.Needs because of construction engineering in the delivery (pipe) line often need multiple some multi-form pipe joints.

Sticking, the weldering of the needs that pipe joint in the past has; Though what have can connect fast, sealing effect is bad; Though what have can connect fast, also has the better seal effect, can not bear pressure, often under very little pressure, will come off the speed of influence construction and the quality of engineering.

Advantages such as the purpose of this utility model is to design a kind of quick, sealing Water supplying tube joint that has the fastening function, and it not only can be connected fast, and good seal performance, high pressure resistant, and the butt joint axial error is little.

The utility model is made up of body, lid, O-ring seal, locking ring, pintle hook lock, and O-ring seal is arranged on the bottom of body connecting end internal orifice sealing platform, and locking ring compresses the end crimping with lid on O-ring seal.

Locking ring is a trip ring, and the ring body inboard is provided with 3-15 pintle hook lock.

Pintle hook lock is a barb type, and barb is at the interior edge face of locking ring, and locking end sticks up in the circle that rides over locking ring.

Using method of the present utility model is as follows: the tubing that will require earlier to connect inserts the utility model along the body connection mouth, rotates lid to lid then and compresses till locking ring and the O-ring seal.At this moment under the effect of O-ring seal and locking ring, tubing and body are tightly connected, and the pintle hook lock on the locking ring is clamped on the outer pipe wall.

Tubing can have the trend of outside slippage because of the increase of pipe internal pressure when pipeline feeds water, at this moment pintle hook lock can self hardness and outside stick into tube wall under the effect of sticking up and make it can not slippage.

The utility model connection need not glued, be welded, and connects quick, good sealing effect, can bear 40-60 atmospheric pressure, is the update product of Water supplying tube joint in the construction engineering, and promotional value and huge market potential are widely arranged.

Fig. 1 is a structural representation of the present utility model, also is specification digest figure, and Fig. 2 is the planimetric map of locking ring, and Fig. 3 is the side sectional view of locking ring.Each label is respectively among the figure: 1 body, 2 lids, 3 O-ring seals, 4 locking rings, 5 pintle hook locks, 6 tubing.

Now in conjunction with the accompanying drawings, the utility model is described in further detail.

Embodiment: body 1, tubing 6, locking ring 4, lid 2 PVC material, it is 50mm that its middle tube body 1 connects internal diameter, long 13mm; The residing seal section internal diameter of O-ring seal is 56mm, long 6mm; The axial angle of the residing cone segments of locking ring is 10 degree, and perpendicular distance is 9mm; O-ring seal 3 usefulness rubber are made, and cross section diameter is 4mm; The locking ring internal diameter is 50mm, maximum outside diameter 60mm; Axial angle 10 degree of cylindrical; Pintle hook lock 5 is 4, makes of stainless steel material, and each long 10mm, wide 4mm, front end are three dentations, are plugged on the inboard of locking ring.
