Description
Technical field
The utility model is related to a kind of bindiny mechanism, particularly a kind of disposable gas cylinder charging joint mechanism.
Background technology
With the continuous expansion of disposable gas cylinder application, increasing field needs to use disposable gas cylinder,
Therefore many different patterns and the disposable gas cylinder charging joint of structure are also occurred in that, cylinder filling joint needs to take into account connection effect
The demand of rate and quality of connection, but now on the market it can be seen that traditional jointing can not balance well therebetween mostly
Relation, or with good air-tightness, but attended operation is complicated, and cost is higher；Or it is with low cost, it is easy to connect, but
The problem of often having certain again in air-tightness.Therefore a kind of method or apparatus that can solve the problem that above mentioned problem is needed now.
The content of the invention
The utility model is that design is ingeniously in order to solve the above-mentioned deficiency present in prior art, propose that one kind is simple in construction
It is wonderful, it is with low cost, connect fast, easily disposable gas cylinder charging joint mechanism.
Technical solution of the present utility model is：A kind of disposable gas cylinder charging joint mechanism, it is characterised in that：It is described
Joint mechanism include the joint body 1 of tubulose, being respectively connected with polytetrafluoroethylene (PTFE) on the top and bottom of joint body 1 quickly connects
First 2, one end of polytetrafluoroethylene (PTFE) snap joint 2 is provided with round table-like plug 3, and round table-like plug 3 and the end of joint body 1
Internal diameter matches, and coupling nut 4 is also threaded with outside the termination of joint body 1, and go back screw thread in the outside of joint body 1
It is connected with hold-doun nut 5.
Collar flange 6 is provided with the middle part of the internal diameter of described polytetrafluoroethylene (PTFE) snap joint 2.
The utility model compared with the existing technology, has the following advantages that：
The disposable gas cylinder charging joint mechanism of this kind of structure type, its is simple in construction, ingenious in design, rationally distributed, it
The variety of problems exposed in use for traditional disposable gas cylinder quick-connect machanism, it is a set of special to design
Bindiny mechanism, it sets one with round table-like respectively by the use of joint body as main body in the upper and lower ends of joint body
Plug, the snap joint that is made up of polytetrafluoroethylene (PTFE), its round table-like plug can allow snap joint quickly and easily to insert
Into joint body, and snap joint possesses certain elasticity, therefore, it is possible to which good sealing effectiveness is effectively ensured；Meanwhile,
A collar flange is also provided with the internal diameter of its snap joint, it can be together with the bottle neck top end face formation of disposable gas cylinder
Sealing surface is contacted, so as to improve the sealing effectiveness between joint mechanism and gas cylinder.And its manufacture craft is simple, is manufactured into
This is cheap, it can be said that it possesses a variety of advantages, is particularly suitable for promoting in the art and answers, its market prospects is very wide
It is wealthy.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of polytetrafluoroethylene (PTFE) snap joint in the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1 and Figure 2：A kind of disposable pneumo
Bottle charging joint mechanism, it includes the joint body 1 of a tubulose, poly- four is respectively connected with the top and bottom of joint body 1
PVF snap joint 2, round table-like plug 3 is provided with one end of polytetrafluoroethylene (PTFE) snap joint 2, and this is round table-like slotting
First 3 are mutually matched with the internal diameter of the end of joint body 1, and connection spiral shell is also threaded with outside the termination of joint body 1
Cap 4, while being also threaded with hold-doun nut 5 in the outside of joint body 1, using hold-doun nut, can consolidate structural body 1
It is scheduled on load plane；
In order to obtain better seal effect, also set up in the middle part of the internal diameter of above-mentioned polytetrafluoroethylene (PTFE) snap joint 2
There is collar flange 6.
The course of work of the disposable gas cylinder charging joint mechanism of the utility model embodiment is as follows：Need to disposable pneumo
When bottle is inflated, a polytetrafluoroethylene (PTFE) snap joint 2 is plugged on loading line first, and ensure the polytetrafluoroethylene (PTFE)
The direction of round table-like plug 3 in snap joint 2 is downwards, then quick by joint body 1 and polytetrafluoroethylene (PTFE) using coupling nut 4
Joint 2 links together, the termination of the fully-inserted joint body 1 of the round table-like plug 3 in polytetrafluoroethylene (PTFE) snap joint 2,
Then it is inserted into a polytetrafluoroethylene (PTFE) snap joint 2 from the lower end of joint body 1（Equally by the polytetrafluoroethylene (PTFE)
Round table-like plug 3 in snap joint 2 inserts the termination of joint body 1）, then the two is connected as one using coupling nut
Structure；Formed a complete joint mechanism, by the joint mechanism positioned at bottom polytetrafluoroethylene (PTFE) snap joint 2 with once
Property gas cylinder on bottle neck be connected, that is, realize the mesh for quickly connecting disposable gas cylinder and loading line using mechanism
's；
Further, a collar flange 6 can be set in the middle part of the internal diameter of polytetrafluoroethylene (PTFE) snap joint 2, and the ring-type is convex
The internal diameter of edge 6 is consistent with the caliber of the bottle neck on disposable gas cylinder, and this structure can allow polytetrafluoroethylene (PTFE) snap joint 2 and bottle
Two contact surfaces are constructed between mouth（That is sealing surface）, first contact surface is the bottom and one of polytetrafluoroethylene (PTFE) snap joint 2
Between the superolateral step of bottle neck of secondary property gas cylinder, second sealing surface be then between the bottom surface of bottle neck top and collar flange 6,
The structure of this double seal face, makes sealing effectiveness therebetween more preferable.
