Embodiment
To further appreciate that content of the present utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.
Embodiment 1
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of band bulge type hard tube snap joint of the present embodiment, as shown in Figure 1, Figure 2 and
Shown in Fig. 3, the snap joint 2 includes Top Crossbeam 21 and lower cross arm 22, and the Top Crossbeam 21 and lower cross arm 22 are hinged by jointed shaft
It is connected, includes upper handle and upper grip by boundary, Top Crossbeam 21 of jointed shaft, lower cross arm 22 includes lower handle and lower chuck, and
Upper handle is correspondingly set up and down with lower handle, upper grip and lower chuck.It should be noted that：The structure difference so designed
In the structure of cross-articulation so that upper handle and lower handle it is close to each other, it may appear that upper grip mutually deviates from lower chuck.
As shown in Figure 1, Figure 2 and Figure 3, more than one guiding that ammunition feed spring 24 is arranged is provided between upper handle and lower handle
Post 23, the lead 23 include upper lead and lower lead, and upper lead is individually fixed in upper handle with lower lead
On handle, lead is correspondingly set up and down with lower lead on this, and lead does not contact with lower lead on this.Need
Bright is：By certain interval between upper lead and lower lead be present, and then cause the spring being set on lead 23
24 can occur compression.The utility model can improve the clamping force of snap joint 2 by increasing the quantity of spring 24, enter
And improve sealing.2 leads 23 that ammunition feed spring 24 is arranged are provided with the present embodiment between upper handle and lower handle.
As shown in figure 1, opening up U-shaped opening 25 along the end face away from jointed shaft on upper grip, the upper grip passes through U-shaped opening
25 are connected on the hard tube 1 for being provided with bulge 11（As shown in figure 4, hard tube 1 can be bend pipe or straight tube with bulge 11）, and should
The lower surface of upper grip is against in bulge 11.It should be noted that：The utility model by designing U-shaped opening on upper grip,
To facilitate the quick connection of pipe.The U-shaped opening is slightly larger than hard tube 1, to ensure U-shaped that hard tube 1 can be connected on upper grip
In opening, and the side of hard tube 1 after clamping contacts with the bottom of U-shaped opening, plays and is preferably oriented to and clamping effect, the U-shaped
Opening is less than bulge 11, to ensure that the lower surface of upper grip can be against in bulge 11.
As shown in figure 3, the inside of lower chuck is disposed with caulking gum 26, transitional pore 27 and screwed hole from top to bottom
28, the axis of the axis of caulking gum 26, transitional pore 27 and screwed hole 28 with hard tube 1 coincides, wherein, hard tube 1
The mouth of pipe is against on caulking gum 26, and the internal diameter of the caulking gum 26 is more than the aperture of transitional pore 27, hard tube 1 by transitional pore 27 with
Screwed hole 28 is connected, and ambient atmosphere is led in the bottom of the screwed hole 28, and then can carry spiral shell with other by the screwed hole 28
The hard tube 1 of line structure is connected.It should be noted that：The structure design of lower chuck can meet between hard tube 1 in the utility model
Air-tightness connection require, meanwhile, by the design of the internal diameter of caulking gum 26 more than the aperture of transitional pore 27, may be such that caulking gum
26 lower surface partly will not vacantly be arranged on the inside of lower chuck, and then ensure that the mouth of pipe of hard tube 1 can be pressed on sealing rubber
The upper surface of glue 26, improve sealing.Specifically in the present embodiment, the material of caulking gum 26 is nitrile rubber, the sealing rubber
The thickness of glue 26 is 2mm.
The specific operation process of hard tube 1 of the clamping of snap joint 2 with bulge 11 is in the utility model：First, pass through
Hand acts on certain force in upper handle and lower handle, with upper handle and close to each other, upper grip and the lower chuck phase of lower handle
Mutually deviate from, enlarged open so that upper grip is located at the top of bulge 11, and lower chuck is located at the lower section of the mouth of pipe of hard tube 1；And then,
Hard tube 1 is clamped in the U-shaped opening on upper grip, now, the caulking gum 26 in lower chuck be located at the mouth of pipe of hard tube 1 just under
Side, then unclamp hand, due to unclamp when, spring 24 be in compressive state, stores certain elastic potential energy so that upper grip and
Lower chuck is close to each other, until the mouth of pipe of hard tube 1 is clamped on caulking gum 26 so that the contraction distortion of caulking gum 26, and upper folder
The lower surface of head is against in bulge 11.It should be noted that：After the completion of pinching action, spring 24 is still in compressive state.It is above-mentioned
Process is the poised state reached when not ventilating.After ventilation, caulking gum 26 is in addition to spring force that can be by spring 24, also
Can be by the pressure of gas, and the pressure of gas is determined by the sectional area and gas pressure intensity of the mouth of pipe, and after ventilation, can further press
Tightening seal rubber 26.It should be noted that：After ventilation, the decrement of spring 24 can increase.
The utility model between upper handle and lower handle by installing spring 24 additional, by the spring force and the arm of force of spring 24
The principle of length compresses the caulking gum 26 of the mouth of pipe of hard tube 1, and then meets sealing property requirement, and the company of the snap joint 2
It is simple to connect mode, it is easy to operate, hence it is evident that air-leakage test efficiency is improved, meanwhile, the snap joint 2 in the utility model is applied to
The quick connection and dismounting of hard tube 1 with bulge 11.
Schematically the utility model and embodiments thereof are described above, this describes no restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So if this area
Those of ordinary skill enlightened by it, do not depart from the utility model create objective in the case of, without creativeness design
The frame mode similar to the technical scheme and embodiment, the scope of protection of the utility model all should be belonged to.
