Abstract

The utility model relates to the technical field of pipeline connecting pieces, in particular to a quick pipe connecting connector. The quick pipe connecting connector comprises a pipe fitting and a corrugated pipe, wherein the body of the pipe fitting is a connector body with external threads, a cap nut is arranged on the corrugated pipe, the cap nut is connected with the connector body in a screwed mode, and two open washers are arranged in portions, between the cap nut and the connector body, inside grooves of the corrugated pipe. According to the quick pipe connecting connector, the cap nut is screwed with the threads on the connector body, the cone-shaped top end on the pipe fitting is meshed with the cut off end socket of the corrugated pipe to form a horn shape along with the screwing of the nut, the pipe fitting and the open washers are matched with one another to pull the end socket portion of the corrugated pipe backward to form a horn mouth, therefore, the aim of sealing metal through metal is achieved, and no special horn mouth manufacturing tool or flattening tool needs to be used.

Description

A kind of fast Tube to tube fittings
Technical field
The utility model relates to the pipe joint technical field, particularly a kind of fast Tube to tube fittings.
Background technique
Flexibility fuel tube (FGP pipe) system is also referred to as corrugated stainless steel (being called for short CSST).Its predecessor is the inside fuel tube of Japan exploitation, and this pipe network is mixed attached pipe fitting with the bellows of rolling and is used for the combustion gas of central supply station is transported to the use everywhere in a building building or house.This technology-imitation is that the mode of house laying circuit is that fuel gas pipeline is laid in the house, thereby reaches the purpose of decrease installation time and labour cost.
For a long time, use three kinds of pipe fittings in the installation at the scene.The pipe fitting that the first enters this field uses fibre washer to reach sealing purpose, and need not professional tool pipe fitting be pacified and connect.But, with the horn-like metalwork that some manufacturer provides the metalwork sealing means to be compared, the installation of this kind pipe fitting still has higher leak rate.The pipe fitting that the second enters this field at first with the flatten spiral of CSST tube head of a kind of professional tool, is then loaded onto pipe fitting, next uses again another kind of professional tool to fill a trumpet-shaped workpiece at tube head.This product has been eliminated from the market, and reason is that stainless steel is made very hard in the process of spiral and installation loudspeaker spare of flattening.The third pipe fitting that enters this field need not use any professional tool.Just the spiral of tube head has been drawn backward and formed a double horn mouth, thereby realized metal to metal seal.Through practicality after a while, it is found that this design can't satisfy the demand of high sealing.
The model utility content
The purpose of this utility model is for the defective of prior art and deficiency, and a kind of compact structure, good airproof performance, fast Tube to tube fittings easy for installation are provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of fast Tube to tube fittings described in the utility model, comprise pipe fitting and bellows, the main body of pipe fitting is for being with externally threaded joint, and described bellows is provided with torx nut, torx nut and joint are spirally connected, and are arranged with two open washers in the bellows groove between torx nut and the joint.
Further, the front end of described joint is provided with conical head, and the open washer inboard has the cone shape hole that cooperates with conical head.
Further, the front end external diameter of described conical head is less than the internal diameter of bellows.
The utility model beneficial effect is: the utility model is by the screw thread twist on torx nut and the joint, and along with tightening of nut, the taper top on the pipe fitting is horn-like and cut-out termination interlock bellows; Pipe fitting cooperates with open washer has drawn horn mouth of formation backward with the termination section of bellows, thereby realizes metal to metal seal, need not to re-use special-purpose flaring tool and smoother.
Description of drawings
Fig. 1 is whole sectional structure schematic diagram of the present utility model.
Among the figure:
1, pipe fitting; 2, bellows; 3, torx nut; 4, open washer;
11, joint; 12, conical head; 41, cone shape hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of fast Tube to tube fittings described in the utility model comprises pipe fitting 1 and bellows 2, and the main body of pipe fitting 1 is for being with externally threaded joint 11, and joint 11 is used for connecting bellows 2; Bellows 2 is provided with torx nut 3, torx nut 3 is spirally connected with joint 11, be arranged with two open washers 4 in bellows 2 grooves between torx nut 3 and the joint 11, the left and right displacement of open washer 4 restriction torx nuts 3, and when torx nut 3 and joint 11 screw, make the port of bellows 2 cooperate docking with conical head 12.
As shown in Figure 1, the front end of joint 11 is provided with conical head 12, and open washer 4 inboards have the cone shape hole 41 that cooperates with conical head 12, and open washer 4 is located at bellows 2 and is cut off a mouthful adjacent groove, and then forms linkage status with bellows 2.
Pipe fitting 1 is as follows with the assembly process of bellows 2, at first bellows 2 is cut off along the groove on the periphery, and bellows 2 after loading onto torx nut 3 is packed open washer 4 near in the groove that cuts off mouth into, torx nut 3 is enclosed within on the open washer 4 again; Along with screwing of torx nut 3 and joint 11, open washer 4 is pushed the cut-out mouth of bellows 2 to conical head 12, it is horn-like that the cut-out mouth of bellows 2 is formed by the impact of conical head 12, and finally form open washer 4, bellows 2 and cut off and mouthful are connected three's tight connection with conical head.
The above only is better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
