The periphery in portion is provided with the first bayonet slot, and the stainless steel belt is sheathed on the periphery of the flexible pipe, and passes through the wolf's fang type
Hasp is fixed on the periphery in the sawtooth portion；
The periphery of the hard tube is provided with the second bayonet slot；
The front end of the end head is docked with the end of the hard tube, and the flexible clip is arranged in first bayonet slot
In second bayonet slot.
Further, it is provided with sealing ring in the flexible clip.
Further, the external diameter of the end head is identical with the external diameter of the hard tube.
Further, the flexible clip is annular in shape, and its opening position close to both sides is convexly equipped with protuberance respectively inwards, and two
The individual protuberance is arranged in first bayonet slot and second bayonet slot respectively.
The utility model has the advantages that：
The front end of the end head is docked with the end of the hard tube, and the flexible clip is arranged in first bayonet slot
In second bayonet slot so that the jointing is connected fastening with the hard tube, then complete the flexible pipe and
The connection of hard tube, it is linked and packed relatively simple, it is also less to assemble required connector, can effectively reduce cost.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation for the aqueous vapor pipeline connecting device that the utility model embodiment provides；
Fig. 2 is the structural representation for the jointing that the utility model embodiment provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, belong to the scope of the utility model protection.
Such as Fig. 1 and Fig. 2, the utility model embodiment provides a kind of aqueous vapor pipeline connecting device, for by flexible pipe 1 and hard tube
2 connections, including jointing 4, stainless steel belt 3, wolf's fang type hasp (not shown) and flexible clip 5.
Such as Fig. 1 and Fig. 2, the jointing 4 includes hollow end head 41 and sawtooth portion 42, and the sawtooth portion 42 is arranged
In in flexible pipe 1, the periphery of the end head 41 is provided with the first bayonet slot 411, and the stainless steel belt 3 is sheathed on the flexible pipe
1 periphery, and it is fixed on by the wolf's fang type hasp periphery in the sawtooth portion 42.The size of the end head 41 is according to scratching
The size of property clip 5 and design, what the sawtooth portion 42 was designed according to the size of flexible pipe 1.Pass through sawtooth portion 42 and institute
State flexible pipe 1 and coordinate fixation, flexible pipe 1 will not fall off；Meanwhile flexible pipe 1 is fastened in sawtooth portion 42 using stainless steel belt 3, protect
The reliability of both connections is demonstrate,proved.
Such as Fig. 1 and Fig. 2, the periphery of the hard tube 2 is provided with the second bayonet slot 21, in this preferred embodiment, described
Two bayonet slots 21 are machined into by slot rolling, and machine-shaping is more convenient.
