But existing tubing string often has noise in control process.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides a kind of and reduces the bolt fastening structure that tubing string regulates noise.
For realizing above-mentioned object, a kind of bolt fastening structure reducing tubing string adjustment noise described in the utility model, comprise tubing string, bolt and bolt slot, described tubing string is provided with support, described support is a space framework, and the bottom surface of described space framework is fixed on described tubing string, and the two sides of described space framework are provided with bolt slot, described bolt is in bolt slot and have gap between described bolt and described bolt slot, and described bolt external diameter is 8.02-8.1mm.
Preferably, described space framework is quadra, and the bolt slot of these framework two sides is symmetrical.
Preferably, described bolt slot is strip shape groove, and described bolt is placed in the cell, and the two ends of this groove are provided with a projection, and the direction of this projection is the position pointing to described bolt.
Preferred, the limit of described bolt slot is provided with zigzag fashion.
Preferably, the bottom of described bolt is provided with circular groove.
The utility model beneficial effect:
Existing tubing string often has noise in control process, investigates discovery after deliberation, be between bolt and bolt slot according to caused by unreasonable.The utility model increases the external diameter of bolt, and bolt slot is provided with zigzag fashion, makes up the gap that both install, and eliminates the abnormal sound in control process, adds circular groove in addition at stud base, fits tightr, be also conducive to eliminating abnormal sound with opponent's part.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1 tubing string, 2 is bolt, and 3 is bolt slot, and 4 is circular groove, and 5 is space framework.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 1, the present embodiment provides a kind of and reduces the bolt fastening structure that tubing string regulates noise, comprise tubing string 1, bolt 2 and bolt slot 3, described tubing string 1 is provided with support, described support is a space framework 5, and the bottom surface of described space framework 5 is fixed on described tubing string 1, and the two sides of described space framework 5 are provided with bolt slot 3, described bolt 2 is in bolt slot 3 and have gap between described bolt 2 and described bolt slot 3, and described bolt 2 external diameter is 8.02-8.1mm.
As a preferred implementation, described space framework 5 is quadra, and the bolt slot 3 of these framework two sides is symmetrical.
As a preferred implementation, described bolt slot 3 is strip shape groove, and described bolt 2 is placed in the cell, and the two ends of this groove are provided with a projection, and the direction of this projection is the position pointing to described bolt 2.
As a preferred implementation, the limit of described bolt slot 3 is provided with zigzag fashion.
As a preferred implementation, the bottom of described bolt 2 is provided with circular groove 4, fits tightr, be conducive to eliminating abnormal sound with opponent's part.
The utility model increases the external diameter of bolt, and bolt slot is provided with zigzag fashion, makes up the gap that both install, and eliminates the abnormal sound in control process, adds circular groove in addition at stud base, fits tightr, be also conducive to eliminating abnormal sound with opponent's part.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
