Abstract
The utility model relates to an anti-off device for a hot-water pipe and overcomes the defects that the hot-water pipe in the prior art is prone to be deformed due to expansion and leakage of a connection portion are formed because the hot-water pipe is directly connected to a connection device. The anti-off device is provided with a central through hole sleeved on the hot-water pipe and a connecting end wherein the connecting end is connected with the connection device, a groove is arranged on the inner wall of the connecting end, the groove is matched with a protrusion arranged on a periphery of the connection device, and the other end of the anti-off device is provided with a tapered sleeve. As the groove is matched with the protrusion, resistance is formed to prevent the hot-water pipe from being off. As the tapered sleeve and the hot-water pipe are sleeved on the connection device and are close to each other, the resistance is exerted along the expansion direction of the hot-water pipe to prevent the hot-water pipe from expanding. Therefore, the hot-water pipe is prevented from leaving the connection device after being heated.
Description
Technical field
The utility model relates to a kind of pipe fitting anti-drop device, especially a kind of hot-water line anti-drop device that prevents that hot-water line from coming off from connection set.
Background technique
Pipe fitting generally all has connection set when connecting, and connects through connection set.Pipe fitting with can guarantee join strength usually after connection set is connected, the phenomenon that pipe fitting separates with connection set can not take place, but this mode is to indeformable pipe fitting, such as cold water pipe.If but to the pipe fitting that deforms easily; Such as hot-water line, the position that hot-water line links to each other with connection set is heated, easily dilatancy; The join strength that hot-water line expands between back and the connection set reduces; Hot-water line comes off from connection set easily, causes to connect to relax, and the phenomenon of seepage possibly take place.
To this problem; The workman is in construction; Usually can tighten with thin wire or nylon wire band at the position that hot-water line is connected with connection set, cumbersome but this mode is operated, working strength of workers is bigger; And some connection part position more complicated, relatively more difficult in the operation.And thin wire or nylon silk ribbon can not tighten when tightening fully, always has the gap, and this just gives to tighten and has brought hidden danger, the phenomenon of seepage also can occur.
Summary of the invention
The utility model has solved and has directly connected hot-water line and connection set in the existing technology; Cause the defective of connection part seepage easily because of dilatancy; A kind of hot-water line anti-drop device is provided; Use auxiliary hot-water line and the connection set of connecting of this device, can also produce the anticreep resistance when playing hoop, thereby realize anticreep.
The utility model has also solved and has used thin wire or nylon silk ribbon to tighten the connection part between hot-water line and the connection set in the existing technology; Cause troublesome poeration, tighten defective completely, a kind of hot-water line anti-drop device is provided; Use auxiliary hot-water line and the connection set of connecting of this device; Simple to operate, hinder hot-water line and expand, improve anticreep power with expansion energy.
The utility model solves the technological scheme that its technical problem adopted: a kind of hot-water line anti-drop device; Has the intermediate throughholes that is nested with on hot-water line; This anti-drop device also has the connecting end that is connected with connection set, the inwall of connecting end be provided with the connection set periphery on the groove that matches of convexity; The other end of this anti-drop device is a taper sheath.The convexity of groove and connection set matches, and to the hot-water line resistance that comes off, taper sheath is pressed close to the position that hot-water line is nested with on the connection set mutually, can give resistance of hot-water line expansion direction, prevents that hot-water line from expanding; Taper sheath and groove can prevent that with protruding cooperating hot-water line from coming off.
As preferably, the end of taper sheath is one section cylindrical sleeve, and cylindrical sleeve is nested with at hot-water line outside.Cylindrical sleeve cooperates with taper sheath and is nested with outside hot-water line, improves the hot-water line expansion resistance, and with hot-water line between cooperate tightr.
As preferably, the inwall between groove and the taper sheath is skewed, and the diameter of groove one side is greater than the diameter of taper sheath one side, and the angle of inclination is 1-5 °.Inwall tilts conveniently to be inserted on the connection set, is convenient to groove and matches with convexity.
As preferably, device is provided with interior chamfering at an end of groove, and the angle of inclination of interior chamfering is 10-30 °.Interior chamfering can play leading role on being nested with connection set the time.
As preferably, the end of connection set is a tapered end, is cylindrical portion between tapered end and the convexity, and the external diameter of cylindrical portion is less than the bigger diameter end diameter of tapered end.Hot-water line is nested with on the connection set, and the end of hot-water line contacts with cylindrical portion, and tapered end becomes stop portion, hot-water line and the Drop-proof effect that can play the first step after connection set links to each other.
As preferably, the angle of inclination of tapered end is 10-30 °.This angle matches with the angle of inclination of device taper sheath.
The beneficial effect of the utility model is: the convexity of groove and connection set matches; To the hot-water line resistance that comes off; Taper sheath is pressed close to the position that hot-water line is nested with on the connection set mutually; Can give resistance of hot-water line expansion direction, prevent that hot-water line from expanding, and then prevent that hot-water line is heated and come off from connection set.
