Description

A kind of installation pipeline pipe clamp

Technical field

The present invention relates to a kind of pipe clamp structure that pipeline is used of installing.

Background technique

For the installation of various flexible pipes, various wire harness on the automobile, the ply-yarn drill of usefulness does not have guide function usually, when being connected to the rigid tubing of rubber hose at the installation two ends, needing two above ply-yarn drills fixed pipelines preferably, but also can't adjust setting angle.Along with Automobile Design is meticulous day by day and compact, this has increased the cost of production and the weight of automobile undoubtedly, because use the clamp that does not have guide function, when mounted, if single-point is fixed, pipeline and clamp can rotate around immovable point unavoidably, will influence the layout of pipeline on automobile like this, and take limited space.For the good mounting type of holding tube line, certainly will increase more clamp, on the other hand, common pipeline clamp except mounting hole, also needs a directional hole if will have installation and orientating function.Like this, the structure and the complex process degree of bodywork parts certainly will have been increased, and the attachment face that requires bodywork parts must be the plane, like this, could satisfy the requirement of punching technology, therefore, design a kind of mounting hole that both only needed, can guarantee the structure of pipeline installation guiding again, it is necessary reducing the body work difficulty, improving pipeline fitting operation convenience.

Summary of the invention

The present invention is directed to the defective that prior art exists, provide a kind of can be to the pipeline angle orientation of installing, and the pipe clamp of adjustable homogeneous tube line trend, adopt this structure neither to need to be increased in the location and installation hole of car body and other car body component, can guarantee the direction that the pipeline assembling needs again, and adjust the setting angle of pipeline as required, simultaneously can improve efficiency of assembling, further, can avoid pipeline on automobile, to install moving towards in disorder and influence attractive in appearance, because the trend of line construction of the present invention can be adjusted, and the position of pipeline and other component and spacing are guaranteed.

Technological scheme of the present invention is as follows:

A kind of installation pipeline pipe clamp, it include the band claw the pipe clamp head, the pipe clamp head is installed to screw and pipe clamp seat on the fixed position.There are some spherical surface hills the lower end surface of pipe clamp head, pipe clamp seat one end is prismatic mounting end, be installed in the mounting hole of respective shapes of fixed component, have on the end face of the other end of pipe clamp seat with respect to being the spherical groove that equal angles is circular layout with the place planar central, the pipe clamp head is connected on the pipe clamp seat by the hemisphere face projection of lower end surface, and there is a hole of passing through that tapping screw is installed at the center of pipe clamp seat.

In addition, tapping screw is installed on the pipe clamp seat is established groove, be provided with flange, cooperatively interact with groove in the corresponding position that fits of pipe clamp head with it by the end in hole.The lower diameter of passing through the hole that tapping screw is installed on the pipe clamp seat is approximately less than the diameter of tapping screw.

When this pipe clamp is installed, prismatic mounting end insertion with the pipe clamp seat earlier has in the fixed component (as the vehicle body component) of mounting hole, guarantee that like this pipe clamp seat is with respect to fixed component relative rotary motion not, want to make the trend of pipeline can adjust or fixing, only need to guarantee that a pipe clamp head can be adjusted or maintain static with respect to the pipe clamp seat gets final product.Therefore then the spherical groove of the spherical surface hill alignment tube deck upper-end surface of pipe clamp head lower end surface is depressed, tighten tapping screw then, the mounting end of pipe clamp seat is along with the screw-in of tapping screw, swollen, guaranteed that like this pipe clamp seat can not split away off from fixed component, so promptly finished the installation of pipe clamp, the claw by the pipe clamp head blocks pipeline, can realize the location.Adjust the trend of pipeline if desired, as long as tapping screw is unclamped, adjust the direction of pipe clamp head, and then tighten screw and get final product.Groove on flange on the pipe clamp head and the pipe clamp seat cooperatively interacts, and its effect is to carry out centralized positioning with the pipe clamp seat.

Further, be the V-structure of molding and forming because the pipe clamp head is installed the structure of pipeline, because the elastic reaction of V-type, the pipe clamp head of same specification can be useful for different big or small pipelines and install.Reduced pipe clamp specification quantity like this.Reduced the link of production management, reduced production costs.On the other hand, the such V-structure holding tube line ingenious structure that can not deviate from pipe clamp.

The present invention can be widely used in the pipeline of various automobiles and install, and other similar engineering field.For the installation of various flexible pipes, various wire harness on the automobile, this pipe clamp has location, guide function, and can adjust the pipeline angle of strike as required flexibly, and is simple in structure, easy for installation.

Embodiment

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this pipe clamp is made of pipe clamp seat 2, the screw 3 of molding and forming pipe clamp head 1 and molding and forming.Pipe clamp seat 2 lower ends are the mounting ends 22 with quadrangular, and the upper end is a garden post 23, have on the end face of garden post with respect to being the spherical groove 21 of equal angular annular spread with the place planar central, and there is corresponding spherical surface hill 11 lower end surface of pipe clamp head 1.When this pipe clamp is installed, mounting end 22 insertions with pipe clamp seat 2 earlier have in the vehicle body component 4 of square perforate, guarantee that like this pipe clamp seat 2 is with respect to vehicle body component 4 relative rotary motion not, want to make the trend of pipeline can adjust or fixing, only need to guarantee that pipe clamp head 1 can adjust or maintain static with respect to pipe clamp seat 2.There is a hole of passing through that tapping screw is installed at center on pipe clamp seat 2, in the end in hole fluted 24, and establish a flange 12 (see figure 4)s in pipe clamp head 1 and the place of fitting in this position, its effect is carried out centralized positioning with pipe clamp seat 2 exactly, in ensuing installation, spherical surface hill 11 on the pipe clamp head 1 is matched with the spherical groove that is circular layout 21 on the pipe clamp seat 2, tighten tapping screw 3 then, the mounting end of the quadrangular of pipe clamp seat 2 is along with the screw-in of tapping screw, it is big to be risen, guaranteed that like this pipe clamp seat 2 can not split away off from the vehicle body component, adjust the trend of pipeline if desired, as long as tapping screw is unclamped, make the direction of pipe clamp head 1, and the spherical groove 21 of relevant position is matched just reach the purpose of adjusting the pipeline trend.

Further, the structure that pipe clamp head 1 is installed pipeline is the structure of the V-type of molding and forming, because the elastic reaction of V-type, the pipe clamp head 1 of same specification goes for different big or small pipelines and installs.Reduced guide pipe calliper lattice quantity like this.Reduced the link of production management, reduced production costs.On the other hand, the such V-structure holding tube line ingenious structure that can not deviate from pipe clamp.
