Abstract
The invention discloses a telescopic joint structure for an exhaust silencer. The telescopic joint structure comprises two locking hoops. Multiple telescopic bodies are connected between the two locking hoops and connected with one another through connecting rings. Each telescopic body is formed by combining a cylindrical telescopic pipe and conic telescopic pipes symmetrically arranged on the two sides of the cylindrical telescopic pipe. One end port of each locking hoop and the two end ports of each connecting ring are provided with clamping transfer grooves matched with the corresponding conic telescopic pipes. By the adoption of the telescopic joint structure, according to the length of the exhaust silencer, the telescopic bodies in the proper number can be selected and used for being assembled on the connecting rings and the two locking hoops, assembling is facilitated due to the arrangement of the clamping transfer grooves, and the requirements of exhaust silencers of different lengths are met.
Description
Technical field
The present invention relates to auto-parts field, particularly relate to a kind of expansion joint structure of muffler.
Background technique
The exhaust silencer of automobile is used to the critical component reducing automobile engine to exhaust noise, and it carrys out stress release treatment by the pulse of reduction, decay exhaust pressure.The inside of silencing apparatus is standing is equipped with expansion joint structure, for the internal stress avoiding silencing apparatus pipeline extension to cause pipeline.Traditional expansion joint structure length is fixed, and can not meet the demand of the muffler of different length.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, a kind of expansion joint structure of muffler is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of expansion joint structure of muffler, comprise two locking straps, several telescopic bodys are connected with between locking strap described in two, be connected by coupling ring between described telescopic body, described telescopic body is combined by a cylindrical telescopic pipe and the tapered telescopic pipe being symmetrically set in its both sides, and described locking strap Single port and coupling ring two-port place are equipped with the clamping turn trough coordinated with tapered telescopic pipe.
Further, the external diameter of described cylindrical telescopic pipe is greater than the external diameter of locking strap, and one end external diameter of described tapered telescopic pipe is equal with the external diameter of cylindrical telescopic pipe, and the external diameter of the other end external diameter and locking strap is equal.
The invention has the beneficial effects as follows:
The present invention can, according to the length of muffler, select the telescopic body of suitable quantity and coupling ring and two locking straps to assemble, and assembling is convenient in the setting of clamping turn trough, meets the demand of the muffler of different length.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-locking strap, 2-tapered telescopic pipe, 3-coupling ring, 4-cylindrical telescopic pipe.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in Figure 1, a kind of expansion joint structure of muffler, comprise two locking straps 1, several telescopic bodys are connected with between locking strap 1 described in two, be connected by coupling ring 3 between described telescopic body, described telescopic body is combined with the tapered telescopic pipe 2 being symmetrically set in its both sides by a cylindrical telescopic pipe 4, and described locking strap 1 Single port and coupling ring 3 two-port place are equipped with the clamping turn trough coordinated with tapered telescopic pipe 2.
Further, the external diameter of described cylindrical telescopic pipe 4 is greater than the external diameter of locking strap 1, and one end external diameter of described tapered telescopic pipe 2 is equal with the external diameter of cylindrical telescopic pipe 4, and the external diameter of the other end external diameter and locking strap 1 is equal.
During use, according to the length of muffler, select the telescopic body of suitable quantity and coupling ring 3 and two locking straps 1 to assemble, assembling is convenient in the setting of clamping turn trough, meets the demand of the muffler of different length.
