Bolt falls on lowest point, can interfere being bonded by dress part and opponent's part in this way, influences the quality of assembly.
Utility model content
The utility model mainly solving the technical problems that provide a kind of not de- bolt of pine predetermined set, can it is pre- it is locking not
De- bolt in assembly above and below vibration, no matter component assembly when be which direction bolt all will not vibration；Make a reservation for put on to be equipped with and open
Mouthful, it can be easy to be snapped on bolt.
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of not de- bolt of pine is provided
With predetermined set, including：Sleeve, sleeve are in tubular type, and the diameter of bore of sleeve gradually increases from sleeve middle and upper part to lower end；It is described
Sleeve side is equipped with opening, and opening penetrates through sleeve lateral wall from sleeve upper end to lower end；The sleeve lateral wall is equipped with several notches,
Notch extends to sleeve middle and upper part from sleeve lower end, and the width of notch is gradually reduced from sleeve lower end to sleeve middle and upper part；It is described
The outer wall of sleeve lower end is equipped with upper back-off and lower back-off, the lower end setting of lower back-off fitting sleeve, the institute on sleeve axial direction
It states and is equipped with an intersegmental gap between back-off and lower back-off.
Further, the upper back-off and lower back-off have several, and upper back-off and lower back-off are along circumference direction point
Cloth is buckled on a circle on sleeve outer wall and forms clamping opening between the lower back-off of a circle.
Further, the upper back-off is staggered with lower back-off.
Further, the outer diameter of the lower back-off gradually increases from sleeve lower end to sleeve upper end, the outer diameter of the upper back-off
It is gradually reduced from sleeve lower end to sleeve upper end.
Further, the outer diameter of the sleeve lower end is more than the outer diameter of sleeve upper end.
Further, the inner wall of the sleeve is from sleeve middle and upper part to arc-shaped setting on the direction of sleeve lower end.
Further, the end face of the sleeve upper end is equipped with a circle bulge loop, and bulge loop internal diameter is identical as the internal diameter of sleeve upper end,
Bulge loop outer diameter is less than the outer diameter of sleeve upper end.
Further, the sleeve is resin material.
The utility model has the beneficial effects that：The utility model being capable of pre- locking not de- bolt vibration, assembly in assembly
When, the power that tool applies very little can be pressed into bolt in hole together with sleeve on bolt, easy to use, be wanted to assembly
Ask low.

Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
It please refers to Fig.1 to Fig. 7, the utility model embodiment includes：
A kind of predetermined set of not de- bolt of pine, including：Sleeve 1, sleeve 1 are in tubular type, and sleeve 1 is resin material, sleeve 1
Diameter of bore gradually increase from sleeve middle and upper part to lower end, the inner wall of sleeve 1 is from sleeve middle and upper part to the direction of sleeve lower end
Upper arc-shaped setting, the outer diameter of 1 lower end of sleeve are more than the outer diameter of sleeve upper end；The end face of sleeve upper end is equipped with a circle bulge loop,
Bulge loop internal diameter is identical as the internal diameter of sleeve upper end, and bulge loop outer diameter is less than the outer diameter of sleeve upper end；1 side of the sleeve is equipped with opening
