Abstract
The utility model relates to a pipe joint, which at least has two joints. The pipe joint has a sealing ring and a shim for preventing water from leaking, and has a joint body which is cast into one body with a screw cap of the joint body, wherein, the inner diameter of the inner bevel of the screw cap of the joint body is gradually wide from an opening portion to inside. The pipe joint has a division cylinder body which extends to a step from the opening portion of the screw cap of the joint body and is perforated by a pipeline; the outer side of one end of the division cylinder body, wherein, the end leads to the step, is provided with a front projecting edge contacted with the cylinder body of the screw cap; the inner side of one end of the division cylinder body, wherein, the end leads to the step, is buried with a metal rabbet. The pipe joint has an inclined conical body composed of the division cylinder body and a rear projecting edge, and a clamping spring for maintaining the distance between the screw cap of the joint body and the inclined conical body. The structure has the advantages of convenient installation, good sealing performance and high durability.
Description
The utility model relates to a kind of pipe coupling, particularly relates to a kind of joint for plastic tube that has two connecting ends at least.
The pipe coupling of using at present is to adopt the structure that is threaded, and this structure is to the quality requirement height of material, and the cost of production height need rotate pipe fitting or joint during installation, installs loaded down with trivial details, inefficiency, long-time use, because of screw threads for fastening, corrosion sometimes.Therefore, replacing, inconvenient maintenance, some plastic fittings, film metal pipe fitting have reduced the intensity of tube head with being threaded, and poor reliability is threaded and causes sealing poor sometimes, needs to twine raw meal belt or coating alite paste, and construction is inconvenient.
The purpose of this utility model provides a kind of pipe coupling of threadless structure, and installment work is simplified, and saves cost, convenient maintenance and replacement, good airproof performance, wide adaptability.
The utility model has adopted following technological scheme for achieving the above object.
Two ends, the left and right sides of the present utility model are respectively arranged with connecting end; with about the perpendicular body of two connecting end center lines be provided with connecting end; each inner chamber at body is provided with step; seal ring; pad; be arranged at the step place; the anti-draw presses on pipe interior; be arranged in the inner chamber of body after socket-connecting with beveled cone; be provided with inclined-plane in the body nut in body nut inboard; around beveled cone, be provided with and cut apart cylindrical body; one connects the gap, lug, nib and back lug, nib before two ends are respectively arranged with about the outside of beveled cone, and preceding lug, nib does not contact with inclined-plane in the body nut; an end of cutting apart cylindrical body is divided into more than 2 at least; be fixed with the prionodont metal tenon in the inboard of cutting apart cylindrical body, its direction is the direction of back lug, nib to preceding lug, nib, and the radian of metal tenon is greater than 90 degree; metal tenon pipeline is fixed in the inner chamber of beveled cone by jump ring, and is fixed by protective cover.Body and body nut cast in one.
The utility model has following characteristics:
1, adopt no worm structure, can make it simple in structure, in conjunction with firm, convenient disassembly.
2, the body of pipe coupling and body nut cast in one, have avoided its extension and come off.
3, because be the metal tenon, therefore, metallic conduit also can closely connect, and has improved its application area.
4, beveled cone alongst is provided with and connects the gap, so institute adapter road out-of-shape when cutting off also can closely connect.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the ssembly drawing of the utility model pipe coupling.
