Abstract
The utility model discloses a connection joint comprising a nut (1), a soldering flake (2) and a sleeve type iron tube (3), wherein the nut (1) is soldered to the soldering flake (2) and the sleeve type iron tube (3) and the soldering flake (2) are formed into a whole. The connecting joint is characterized by less processing procedures and long service life.
Description
Technical field
The utility model relates to a kind of hose coupling, is specifically a kind of jointing that connects Brake hose for brake system of car.
Background technique
The jointing of prior art comprises a nut, a weld tabs and a telescopic iron pipe, and described nut, iron pipe all weld with weld tabs.During use, adopt the mode of withholding to be installed on Brake hose intermediate portion at sleeve pipe position, then be installed in system, therefore just played the fixedly effect of Brake hose.There is following defect in the jointing of said structure: because above-mentioned jointing is welded through two places in actual using process, therefore not only manufacturing procedure is many, processing cost is high, and a plurality of welding parts are in use fragile, thereby affect the working life of jointing.
Model utility content
The technical problems to be solved in the utility model is, overcomes the defect of above prior art, and the jointing of the few and long service life of a kind of manufacturing procedure is provided.
The technical solution of the utility model is, a kind of jointing is provided, and comprises a nut, a weld tabs and a telescopic iron pipe, described nut and weld tabs welding, and described telescopic iron pipe and weld tabs are an integral body.
Described telescopic iron pipe and weld tabs are formed by the disposable cold-heading of tubular member.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
The utility model jointing becomes a place by two places welding and welds, and therefore not only manufacturing procedure is few, processing cost is low, and the minimizing of welding part makes it in use fragile, thereby has guaranteed the working life of jointing.
As improvement, described nut and weld tabs are electric resistance welding, and the manufacturing efficiency of the utility model jointing and welding quality are all improved.
Accompanying drawing explanation
Fig. 1 be the utility model jointing partly cut open figure.
Shown in figure 1, nut, 2, weld tabs, 3, sleeve, 4, solder joint.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of jointing of the utility model, comprise a nut 1, weld tabs 2 and a telescopic iron pipe 3, described nut 1 and weld tabs 2 welding, described telescopic iron pipe 3 is an integral body with weld tabs 2, described telescopic iron pipe 3 and weld tabs 2 are formed by the disposable cold-heading of tubular member, and described telescopic iron pipe 3 and weld tabs 2 are put into mould by tubular member and carried out a cold-heading and can form.
Described nut 1 is electric resistance welding with weld tabs 2, forms solder joint 4.Wherein telescopic iron pipe 3 is for connecting Brake hose, and nut 1 is fixing for jointing.
Below only with regard to most preferred embodiment of the present utility model, be described, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.In every case the various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
