Description
Technical field
The utility model relates to the technical field of automobile, espespecially a kind of single collar joint.
Background technique
For collar joint, in general, Europe, particularly the product of Germany is taking single deck tape-recorder cover as main, and the U.S. or the product in Asia are taking double card cover as main, and the main cause creating a difference is the material of cutting ferrule.The cutting ferrule in Europe adopts specific alloy, and amount of deformation is large, can ensure tight seal, simultaneously again can proof strength.And other product is because material is poor, cannot meet cutting ferrule should the large intensity again of amount of deformation reach high requirement simultaneously, have to adopt double card structure.For double card bell and spigot joint, not only its production and processing cost is higher, complex process, and in assembling using process also relative complex.
On new energy natural gas bus, the pipe joint that in gas burning system, metal copper pipe uses is two collar joints, existing pair of collar joint is made up of cutting ferrule nut, front cutting ferrule, rear cutting ferrule, four parts of fittings body, due to special Environmental Conditions (passenger-carrying chassis is the state in the vibrations of jolting often), reduce the reliability and the possibility that has increased joint gas leakage of joint sealing.Therefore in the Environmental Conditions of the long-term vibration of passenger vehicle, there is the easily phenomenon of leakage of combustion gas in the joint of existing double card nested structure.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of single collar joint, and it is overlapped on the basis of same material in use and double card, has both ensured the tight seal that pipeline connects, and higher intensity is provided again.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of single collar joint, comprises fittings body, cutting ferrule nut and cutting ferrule; This fittings body is that hollow article and pipe are connected, and its inwall end is provided with internal conical surface; This cutting ferrule nut one end is that wide mouth end is threaded with this fittings body, and the other end is that slot end coordinates with this pipe, and the changeover portion of the inwall of this cutting ferrule nut from slot end to wide mouth end is provided with internal conical surface and step surface successively; This cutting ferrule is enclosed within described pipe outside, its two ends are respectively equipped with the first outer conical surface and the second outer conical surface, two outer conical surface coordinate with the internal conical surface of fittings body and cutting ferrule nut respectively, and between this two outer conical surface, be provided with convex shoulder, the side that this convex shoulder is connected with described the second outer conical surface coordinates with the step surface of described cutting ferrule nut.
The step surface of described cutting ferrule nut is the conical surface, and the side that the convex shoulder of the described cutting ferrule coordinating is with it connected with described the second outer conical surface is also the conical surface.
Adopt after such scheme, the utlity model has following effectively effect:
1. the design of cutting ferrule described in the utility model two ends outer conical surface, in the time that screwing, cutting ferrule nut also can coordinate with the internal conical surface of fittings body and nut respectively, both ensured the tight seal that pipeline connects, avoid gas leakage, the acting in conjunction of two outer conical surface can reduce again the amount of deformation of cutting ferrule greatly;
2. the convex shoulder of cutting ferrule described in the utility model design, can transmit power on the one hand, can also prevent that on the one hand cutting ferrule is loosening, thereby avoid, in the Environmental Conditions of long-term vibration of passenger vehicle, having the phenomenon of gas leakage, has improved the usage safety performance of product.
In a word, the utility model only adopts single deck tape-recorder nested structure, can make it overlap on the basis of same material in use and double card, has both ensured the tight seal that pipeline connects, and higher intensity is provided again.

Fig. 2 is the structural representation of cutting ferrule described in the utility model;
Fig. 3 is the structural representation of cutting ferrule nut described in the utility model;
Fig. 4 is the structural representation of fittings body described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
What the utility model disclosed is a kind of single collar joint, as shown in Figures 1 to 4, is preferred embodiment of the present utility model.Described joint comprises fittings body 1, cutting ferrule nut 2 and cutting ferrule 3.Wherein:
Described fittings body 1 is hollow article, and in order to be connected with pipe 4, the inwall end of this fittings body 1 is provided with internal conical surface 11.
Described cutting ferrule nut 2 one end are that wide mouth end is threaded with described fittings body 1, and the other end is that slot end coordinates with described pipe 4.The changeover portion of described cutting ferrule nut 2 inwalls from slot end to wide mouth end is provided with internal conical surface 21 and step surface 22 successively.
Described cutting ferrule 3 is enclosed within described pipe 4 outsides, the two ends of this cutting ferrule 3 are respectively equipped with the first outer conical surface 31 and the second outer conical surface 33, two outer conical surface 31,33 coordinate with the internal conical surface 11,21 of fittings body 1 and cutting ferrule nut 2 respectively, and between this first outer conical surface 31 and the second outer conical surface 33, be provided with convex shoulder 32, the side 34 that this convex shoulder 32 is connected with described the second outer conical surface 33 coordinates with the step surface 22 of described cutting ferrule nut 2.
When assembling, in the time that cutting ferrule nut 2 and fittings body 1 screw thread screw, cutting ferrule nut 2 contacts with the convex shoulder 32 of described cutting ferrule 3 by its step surface 22, power is passed to cutting ferrule 3, thereby make the first outer conical surface 31 of cutting ferrule 3 and the second outer conical surface 33 contact and be out of shape with the internal conical surface 11 of fittings body 1 and the internal conical surface 21 of cutting ferrule nut 2 respectively, and then make cutting ferrule 3 hold pipe 4 tightly, reach the requirement of line seal.
Further, the step surface 22 of described cutting ferrule nut 2 can be the conical surface, and the side 34 that the convex shoulder 32 of the described cutting ferrule 3 coordinating is with it connected with described the second outer conical surface 33 is also the conical surface.Like this, after the step surface 22 of this cutting ferrule nut 2 and the convex shoulder 32 of described cutting ferrule 3 contact, not only can transmit power, can also prevent from becoming flexible.And due to the acting in conjunction of first, second outer conical surface 31,33 of cutting ferrule 3, can greatly reduce the amount of deformation of cutting ferrule.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, thus variation or the modification in every case done according to claim of the present utility model and specification, within all should belonging to the scope that the utility model patent contains.
