In order to achieve the above objectives, the technical solution adopted in the utility model is:
The utility model provides a kind of cinch bolt, including sleeve, bolt body and nut, and the sleeve is arranged in fixation
In the fixation hole opened on face, bolt body is threaded through in sleeve, and nut and the bolt body are threadedly engaged, drive the spiral shell
Bolt ontology precession or back-out in the sleeve are provided at least in the position that the side of the sleeve is located at the lower part of the sleeve
Two through slots, the through slot are parallel to the axial setting of the sleeve, and the bolt body is integrally in the form of a column, bolt body it is upper
Portion is provided with the screw thread matched with the nut, and bottom has tapered top brace part, as the bolt body is in the set
Precession in cylinder, the lower part that the top brace part can strut the sleeve makes the sleeve swelling in the fixation hole.
Further, the top of the bolt body opens up the total length that length shared by threaded portion is the bolt body
One third to half.
Further, the top on the side of the sleeve positioned at the through slot is provided with circular through-hole.
Further, multiple latches, the multiple latch staggered row are formed on the lateral wall of the lower part of the sleeve
Cloth is on the lateral surface of the sleeve.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
The cinch bolt of the utility model struts the lower part of sleeve by bolt body, so that sleeve is to outreach
It opens, stuck in stationary plane, whole good fixing effect, and the structure of upper cartridge will not change, so that cinch bolt
External structure will not change, it is not only beautiful, and upper sleeve can play limit effect well.
Further, possessed latch can be caught in stationary plane, such as wall when sleeve stress struts on the outside of sleeve
In face, floor, to improve the whole fixed effect of bolt, it will not be shaken in fixation hole.
Detailed description of the invention
Some specific realities of the utility model are described in detail by way of example and not limitation with reference to the accompanying drawings hereinafter
Apply example.Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing:
Fig. 1 is shown according to the structure of the shock-damping structure for being applied to the suspension of rear-wheel McPherson of the utility model one embodiment
It is intended to.
Wherein, the reference numerals are as follows:
1, sleeve, 11, claw, 111, latch, 12, through-hole；
2, bolt body, 21, top brace part；
3, nut.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
Present embodiment describes a kind of cinch bolts, as shown in Figure 1 comprising sleeve, bolt body 2 and nut 3, it is described
Sleeve 1 is arranged in the fixation hole opened on stationary plane, and bolt body 2 is threaded through in sleeve 1, nut 3 and the bolt body 2
It is threadedly engaged, drives the bolt body 2 precession or back-out in the sleeve 1, be located at the set in the side of the sleeve 1
The position of the lower part of cylinder 1 is provided with three through slots, 1 lower part of sleeve is separated into the claw 11 that three pieces can be softened, the through slot is flat
Row is in the axial direction setting of the sleeve 1, and the bolt body 2 is whole to be in the form of a column, and the top of bolt body 2 is provided with and the nut
3 screw threads matched, bottom has tapered top brace part 21, with the bolt body 2 precession in the sleeve 1, institute
It states top brace part 21 and can strut the claw 11 of the sleeve 1 and make 1 swelling of sleeve in the fixation hole.
The cinch bolt of the utility model struts the claw 11 of sleeve 1 by bolt body 2, so that under sleeve 1
The claw 11 in portion is unfolded outward, stuck in stationary plane, whole good fixing effect, and the structure on 1 top of sleeve will not occur
Variation, so that the external structure of cinch bolt will not change, it is not only beautiful, and upper sleeve 1 can play well
Limit effect.
By stress deformation when 1 claw 11 of sleeve struts in order to prevent, positioned at the through slot on the side of the sleeve 1
The top is provided with circular through-hole 12.In this way when sleeve 1 is softened, upper part would not show tearing shape, prevent sleeve 1
Stress damage, influences the service life of bolt
In order to guarantee bolt body 2 normal precession or back-out in sleeve 1, while shoring the claw 11 of 1 lower part of sleeve, institute
The top for stating bolt body 2 opens up the half for the total length that length shared by threaded portion is the bolt body 2.
In addition, forming multiple latches 111 on the lateral wall of the lower part of the sleeve 1, the multiple latch 111 interlocks
It is arranged on the lateral surface of the sleeve 1.It is so-called staggered, refer to that position of the latch 111 on each claw 11 is located at
Different height so enables to tensile strength of the claw 11 in stationary plane higher.The latch possessed by 1 outside of sleeve
111 can be caught in stationary plane, such as metope, floor when 1 stress of sleeve struts, thus the fixed effect of the entirety for improving bolt
Fruit will not shake in fixation hole.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention,
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
