Abstract

The utility model relates to a brake pipeline connecting piece which adopts a two-way joint connection between pipelines, mainly including an oil pipe and a two-way joint. The ports of two oil pipe sections are just face-to-face. The brake pipeline connecting piece is characterized in that the ends of the oil pipes is provided with tube bolts, and the two-way joint is sheathed in the outside of the pipe bolt with a convex ring arranged. The utility model not only has the advantages of simple structure, reasonable design, but also has a good sealing performance for the cooperation between the port shape of the oil pipe and the end surface shape of the convex ring which makes the oil pipe be not easy to leak oil after assembling, and in particularly to playing a very good connection role between two-section or multi-section pipes which solves problems of inconvenient transportation and easy deformation of long pipes. The utility model promotes rapid installation of the oil pipes in a high work station or low work station through the connection to oil pipes.

Description

The link of braking line

Technical field

The utility model relates to a kind of pipeline connecting device, especially relates to the link that adopts the continuous braking line of two pass joints between a kind of pipeline.

Background technique

At present, the pipeline of automobile generally all is installed on the automobile by pipe and forms, tubing is a double-layer pipe, form with thick 0.35mm roll of steel plate 720 degree, when pipe in when transportation, basic way is to pinion the flex point (flex point is exactly the curved place of pipe) of pipe with line, makes it be not easy distortion.But it is longer to work as pipe, and flex point more for a long time, and pipe is held together with regard to difficult, and also bad placement is made troubles to transportation; And, the long easier just shape of pipe.On production line during entrucking, the branch that high station and low station are arranged, longer pipe (as left back braking hard tube and right back braking hard tube) encloses by the floor in the past and is connected to (preceding adorning at low station of placing on the break, and be at high station dress under the floor), this two tubes is installed very trouble, easy deformation very, and take time.

The model utility content

The utility model mainly is to solve the technical problem that the existing in prior technology pipe is installed comparatively inconvenience etc., provides a kind of by a short pipe is coupled together, and makes pipe that the link of braking line comparatively fast and easily is installed.

The utility model also solves the existing in prior technology pipe simultaneously and is difficult for transportation, the technical problem of easy deformation etc., and providing a kind of can couple together pipe, makes that pipe conveniently transports, the link of on-deformable braking line.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of link of braking line, comprise oil pipe and two pass joints, the port of two sections oil pipes faces, it is characterized in that: the end of described oil pipe will be provided with the pipe bolt, described two pass joints are set in the outside of pipe bolt, are provided with bulge loop in described two pass joints.The pipe bolt sleeve is located at the port of oil pipe, and be fixed together with oil pipe, by two pass joints two pipe bolts are connected and fixed again, structure is very simple, assemble also very quick, solved the transportation inconvenience of long tube and the problem of easy deformation,, made it to install rapidly at high station or low station owing to long tube can be formed by connecting by the pipe of two sections or multistage.

As preferably, described bulge loop and two pass joints are coaxial setting, and the axial cross section of bulge loop is an isosceles trapezoid.Section with the bundle of planes bulge loop through shaft axis, its cross section is two isosceles trapezoids with the shaft axis symmetry.

As preferably, described bulge loop is located at the centre of two pass joints.Bulge loop is located at the centre of two pass joints and is fixed together with two pass joints, helps the soundness of oil pipe and two pass joints assembling, is difficult for loosening.

As preferably, the external diameter of described pipe bolt is suitable mutually with the internal diameter of two pass joints.Two pass joints are set in the pipe bolt outside, the pipe bolt is lived, thereby two sections oil pipes are coupled together.

As preferably, the port shape of described oil pipe matches with the end surface shape of bulge loop.The port shape of oil pipe matches with the end surface shape of bulge loop, makes both be fitted to each other back not easy oil leakage of oil pipe, and sealability is better.

As preferably, the internal diameter of described bulge loop size is basic identical with the internal diameter size of oil pipe.After two sections oil pipes link together by two pass joints, oil flows from one section oil pipe wherein, then carry out the transition in the oil pipe of another section through the internal diameter of bulge loop, the internal diameter of bulge loop size is basic identical with the internal diameter size of oil pipe, makes that oil flowing in oil pipe is comparatively unobstructed.

Therefore, the utlity model has and not only have characteristics simple in structure, reasonable in design, also because the port shape of oil pipe matches with the end surface shape of bulge loop, make both be fitted to each other not easy oil leakage of oil pipe afterwards, sealability is better; Especially be that two sections or multistage pipe play good interconnect function, solved the transportation inconvenience of long tube and the problem of easy deformation,, make oil pipe to install rapidly at high station or low station by the connection of the utility model to oil pipe.

Accompanying drawing 1 is a kind of structural representation of the present utility model;

Accompanying drawing 2 is sectional views of oil pipe of the present utility model;

Accompanying drawing 3 is axial sectional views of two pass joints of the present utility model.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: the link of braking line, comprise that the port of

oil pipe

1 and 3, two sections oil pipes 1 of two pass joints faces, and the end of oil pipe 1 is arranged with the outside that pipe bolt 2, two pass joints 3 are set in pipe bolt 2, is provided with bulge loop 4 in two pass joints 3; Bulge loop 4 and two pass joints 3 are coaxial setting, and the axial cross section of bulge loop 4 is isosceles trapezoid, promptly section with the bundle of planes bulge loop 4 through shaft axis, and its cross section is two isosceles trapezoids with the shaft axis symmetry (referring to accompanying drawings 3).Bulge loop 4 is located at the centre of two pass joints 3 and both are fixed with each other.The external diameter of pipe bolt 2 is suitable mutually with the internal diameter of two pass joints 3.The port shape of oil pipe 1 matches with the end surface shape of bulge loop 4, and the internal diameter size of bulge loop 4 is identical with the internal diameter size of oil pipe 1.

After with the utility model two sections oil pipes 1 being connected, oil is from wherein flowing in one section the oil pipe 1, and the inside of the bulge loop 4 of flowing through again arrives another section oil pipe 1, thereby two sections disjunct oil pipes 1 of script are coupled together.
