Description
Technical field
This utility model relates to a kind of snap joint.
Background technology
Current snap joint, generally comprises the body of a tubular, and one end of body is provided with connection member, when body be inserted into this most internal after, body is fixed by connection member, to reach the purpose quickly connected.
But in above-mentioned snap joint, connection member is usually threaded on body, thus makes connection member install and more bother, so that this snap joint assembling more bothers.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of snap joint, and its assembling is more convenient.
For solving above-mentioned technical problem, the snap joint that this utility model provides, it includes:
The body of one tubular, this body has axially extending bore, and the end face of body is provided with axially extended plastic sheath, and one end away from body of plastic sheath is provided with the clamping part extended radially inwardly；
One snapping sleeve, this snapping sleeve is nested with in plastic sheath and is connected with clamping part snapping；
One grafting sleeve, this grafting sleeve is nested with in snapping sleeve and fixes with snapping sleeve snapping；
One jump ring, this jump ring is arranged in snapping sleeve, jump ring includes the first annulus radially extended and a tapered portion, the periphery wall of the first annulus offsets with the inwall of snapping sleeve, the internal perisporium of the first annulus is connected with one end being relatively large in diameter of tapered portion, one end that the diameter of tapered portion is less is free end, one end being relatively large in diameter of tapered portion near grafting sleeve, the less one end of the diameter of tapered portion with away from grafting sleeve.
As preferably, being equipped with a packing ring in described snapping sleeve, jump ring is between packing ring and grafting sleeve.
As preferably, the periphery wall of described plastic sheath being equipped with a metallic sheath, one end of metallic sheath offsets with body, and the other end of metallic sheath connects a radial direction ring portion, and radially ring portion engages with snapping sleeve.
After using above structure, this utility model compared with prior art, has the advantage that
In this utility model, connection member is made up of snapping sleeve, grafting sleeve and jump ring, after snapping sleeve, grafting sleeve and jump ring have assembled, have only to be inserted in plastic sheath connection member entirety, now snapping sleeve is fixed with clamping part snapping, connection member is thus made to install more convenient, so that this snap joint assembling is more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With detailed description of the invention, this utility model is described in more detail below in conjunction with the accompanying drawings.
As shown in Figure 1, this utility model snap joint includes body 1, snapping sleeve 2, grafting sleeve 3, jump ring 4 of a tubular.
This body 1 has axially extending bore, and the end face of body 1 is provided with axially extended plastic sheath 101, and body 1 is made of plastics, and body 1 is one-body molded with plastic sheath 101, and one end away from body 1 of plastic sheath 101 is provided with the clamping part 102 extended radially inwardly.
This snapping sleeve 2 is nested with in plastic sheath 101 and is connected with clamping part 102 snapping.
This grafting sleeve 3 is nested with in snapping sleeve 2 and fixes with snapping sleeve 2 snapping.
This jump ring 4 is arranged in snapping sleeve 2, jump ring 4 includes first annulus 401 and the tapered portion 402 radially extended, first annulus 401 and tapered portion 402 are one-body molded, the periphery wall of the first annulus 401 offsets with the inwall of snapping sleeve 2, the internal perisporium of the first annulus 401 is connected with one end being relatively large in diameter of tapered portion 402, one end that the diameter of tapered portion 402 is less is free end, one end being relatively large in diameter of tapered portion 402 near grafting sleeve 3, the less one end of the diameter of tapered portion 402 with away from grafting sleeve 3.
During by this snap joint connection pipe body, being inserted into by body in grafting sleeve 3, make body run through grafting sleeve 3, now, body banding is fixed by jump ring 4, completes the quick connection of body.
Being equipped with a packing ring 5 in described snapping sleeve 2, jump ring 4 is between packing ring 5 and grafting sleeve 3, and so, jump ring 4 can be carried out spacing by packing ring 5.
A metallic sheath 6 it is equipped with on the periphery wall of described plastic sheath 101; one end of metallic sheath 6 offsets with body 1; the other end of metallic sheath 6 connects a radial direction ring portion 601; radially ring portion 601 engages with snapping sleeve 2; so; plastic sheath 101 can be protected by metallic sheath 6, it is to avoid plastic sheath 101 is collided and damaged.
Below only applying preferably example to be made that explanation with regard to this utility model, but be not to be construed as limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes made in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
