Abstract
The utility model provides a connecting device for rubber tubes with different diameters. The connecting device comprises a connecting body, wherein the outer diameter of the connecting body is greater than the inner diameter of a connected thick rubber tube, and the outer end part of the connecting body is partially overlapped with that of the connected thick rubber tube to form interference fit; the inner diameter of the connecting body is smaller than the outer diameter of a connected thin rubber tube, and the outer end part of the connecting body is partially overlapped with that of the connected thin rubber tube to form interference fit. According to the scheme, the sealing performance of a joint is preliminarily ensured by the interference fit; the joint is locked by using a hoop preferentially, then is locked by using a binding belt, and then is glued to be prevented from sliding relatively; in addition, a convex ring and a concave ring are arranged at two ends of the connecting body to further ensure the sealing property and the connecting reliability; a rubber hose serves as the connecting body and ensures the communication performance and heat conducting performance of a pipeline.
Description
Technical field
The utility model relates to automobile pipeline interconnection technique field, refers to especially a kind of connection set of different-diameter rubber pipe.
Background technique
In the car load of automobile, pipeline is numerous, and how the pipeline of different bores is carried out to connection effectively is reliably technical barrier always.
The normal rubber pipe that adopts flange to connect two different bores in prior art, it is the port that connects two rubber pipes with metal flange, the port of flange both sides is enclosed within the inside by rubber hose respectively.But, connection metal flange in the middle of rubber material, quality is large, and center of gravity concentrates on metal part, wastes metallic material simultaneously, the heat conduction of material, sealability disunity.
In prior art, also adopt a kind of special rubber pipe that footpath rubber pipe connects two different bores that straightens, between two pipes of joint, fill the material of other suitable thickness, and gluing encapsulation.But special to straighten footpath rubber hose technical difficulty high, be not easy to processing; Fill other materials and easily cause the sudden change of jointing bore, be unfavorable for passing through of fluid, and even block fluid.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of connection set of different-diameter rubber pipe, the problem such as poor performance or technology difficulty height existing to solve Placement of the prior art.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of connection set of different-diameter rubber pipe, comprise connection body, the external diameter of described connection body is greater than the internal diameter that is connected crude rubber pipe, and with described be connected crude rubber pipe outside end sections overlap form interference fit; The internal diameter of described connection body is less than the external diameter that is connected thin rubber pipe, and with described be connected thin rubber pipe outside end sections overlap form interference fit.
Wherein, the outer side wall that is connected crude rubber Guan Shangyu connection body overlapping position described in is provided with clip one; On described connection body, be provided with clip two with the outer side wall that is connected thin rubber pipe overlapping position.
Wherein, the outer side wall that is connected crude rubber Guan Shangyu connection body overlapping position described in is provided with band one; On described connection body, be provided with band two with the outer side wall that is connected thin rubber pipe overlapping position.
Wherein, described connection body two ends are provided with gluing with the junction surface that is connected crude rubber pipe, be connected thin rubber pipe.
Wherein, on the circumferential surface at the two ends of described connection body, be respectively equipped with bulge loop and scrobicular ring.
Wherein, described connection body is rubber hose.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, the sealability of joint is tentatively ensured by interference fit, and preferentially use locked clip device in its connection, secondly use band, gluing again, be used for preventing its relative sliding, be provided with bulge loop and scrobicular ring is further guaranteed its sealing and connection reliability connecting body two ends in addition; By rubber hose, as connecting body, this material ensures connectivity and the heat-conducting property of pipeline.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model, for the problem such as poor performance or technology difficulty height of Placement existence of the prior art, provides a kind of connection set of different-diameter rubber pipe.
As shown in Figure 1, embodiment of the present utility model provides a kind of connection set of different-diameter rubber pipe, comprise rubber hose 1, the external diameter of described rubber hose 1 is greater than the internal diameter that is connected crude rubber pipe 2, and with described be connected crude rubber pipe 2 outside end sections overlap and form interference fit, interference fit has tentatively ensured the sealability that pipeline connects; The internal diameter of described rubber hose 1 is less than the external diameter that is connected thin rubber pipe 3, and with described be connected thin rubber pipe 3 outside end sections overlap form interference fit.
Further, described in, be connected on crude rubber pipe 2 and be provided with clip one or band 1 with the outer side wall of rubber hose 1 overlapping position; In described rubber hose 1, be provided with clip two or band 25 with the outer side wall that is connected thin rubber pipe 3 overlapping positions.On the circumferential surface at the two ends of described rubber hose 1, be respectively equipped with bulge loop 101 and scrobicular ring 102, it can further ensure sealability and connection reliability that pipeline connects.
For example, being connected crude rubber pipe 2 internal diameters is 26mm, and external diameter is 30mm, and being connected thin rubber pipe 3 external diameters is 24mm, and internal diameter is 20mm, and rubber hose 1 should be chosen internal diameter and be about 23mm, and external diameter is about 27mm.
As shown in Figure 2, described rubber hose 1 two ends are provided with gluing 6 with the junction surface that is connected crude rubber pipe 2, be connected thin rubber pipe 3, adopt gluing technological means can make pipeline outward appearance clean and tidy, attractive in appearance.
In such scheme, its reasonable in design, the sealability of joint is tentatively ensured by interference fit, and preferentially use locked clip device in its connection, secondly use band, gluing again, for preventing its relative sliding, is provided with bulge loop and scrobicular ring is further guaranteed its sealing and connection reliability connecting body two ends in addition; By rubber hose, as connecting body, this material ensures connectivity and the heat-conducting property of pipeline.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
