Background

With the continuous improvement of the life quality of people, the requirements on automobiles tend to be diversified, and the arrangement of the engine rooms of the automobiles is more and more compact. The smart production of automobile manufacturing enterprise merges into production technology, strengthens technology beat control, and the clamp is a tool that hose and hard tube were used commonly when connecting, and current clamp is more random when connecting, and it screws up the in-process and all can produce the aversion in axial and footpath, nevertheless the assembly requirement of higher is proposed to the pipeline of clamp fastening in the industry now: the installation and the fastening are convenient, the assembling working hour is less than 60 seconds, and the safety distance between the fixed position and the peripheral parts is kept after the fastening.

Here, it is necessary to design a pipe clamp for self-positioning, which is used to solve the problems of easy installation and fastening, small assembling time, etc., and the requirements of securing the position after fastening and maintaining the safety distance with the peripheral parts.

Disclosure of Invention

In view of the above problems, the present invention aims to provide a self-positioning structure for a clamp of a vulcanized rubber pipe of an air filter, which can realize quick connection between the vulcanized pipe and a hard pipe and can realize self-positioning of the clamp during operation.

The technical scheme of the invention is that the self-positioning structure of the clamp of the vulcanized rubber pipeline of the air filter comprises a hose and a clamp, the end of the hose is provided with an annular positioning groove which is provided with a positioning column, the diameter of the outer end of the positioning column is larger than that of the rod part, the clamp comprises a clamp belt and an end screw part, the clamping band is provided with a positioning long hole along the circumferential direction close to the end screw rod part, the width of the positioning long hole is smaller than the diameter of the outer end of the positioning column, the width of the rod part of the positioning column is matched with the width of the positioning long hole, the end head of the positioning long hole is provided with a clamping end, the inner diameter of the clamping end is larger than the diameter of the outer end head of the positioning column, the annular positioning groove is provided with a limiting block, the end screw rod portion is clamped into the limiting block and then is in a limiting state in the circumferential direction, and the screw tightening clamp belt on the end screw rod portion is tightened to fixedly connect the hose to the hard pipe.

Preferably, the number of stopper is four, and two of them are located two places around the left side of annular positioning groove, and two other correspondence are located two places around the right side of annular positioning groove, end screw rod portion card is gone into behind four stoppers and is spacing around the circumferencial direction realization.

The clamp head fixing device meets the requirements that a hose is connected to a hard pipe, the fixing of the mounting position of the bolt head of the clamp and the orientation of the bolt head are consistent, the design clearance and the production assembly performance are met, the displacement phenomenon cannot occur in the operation process of the clamp, the requirement on the design space of an air filter is reduced, the design space of an engine compartment of a whole vehicle is facilitated in space, and the mounting speed is increased.
