Abstract
The utility model provides a bolt anti -loosening component, is including connecting and the bush, and wherein, the cover is equipped with the auricle on the bush, opens jaggedly on the auricle to position connecting with the breach clearance fit installation of bush is provided with little boss, during the installation blocks the breach of bush the little boss of joint, and the bolt inserts the bush and passes and connects through the nut fastening. The utility model discloses an optimize bush and joint design and in order to reach locking purpose just, adopt clearance fit between joint and bush to realizing the convenient dismouting of bush, can not making joint, bush impaired during the dismantlement, the bush can use repeatedly, has effectively reduced manufacturing cost.
Description
Technical field
The utility model is related to frame for movement technical field, more particularly to a kind of screw retention device.
Background technology
It is the wearability and crushing strength for improving joint in Design of Mechanical Structure, is usually pressed in joint connecting hole
Intensity is high, the more preferable bushing of wearability, while the locking efficiency to ensure bushing, is generally matched somebody with somebody between joint and bushing using interference
Close, this will cause bushing dress, tear difficulty open, and bushing is easily damaged when need to be installed using specific purpose tool, and be dismantled, and then causes bushing
The problems such as surface protection fails, now bushing it is impaired and cannot Reusability；And the fatigue strength to frame for movement and resistance to
Long property has an impact, and may more seriously cause bush hole surrounding mechanical structural damage, or even destruction joint.
Utility model content
The technical problem that the utility model is solved is to provide a kind of screw retention device, to solve above-mentioned background technology
Described in shortcoming.
The technical problem that the utility model is solved employs the following technical solutions to realize：
A kind of screw retention device, including joint and bushing, wherein, auricle is set with bushing, breach is provided with auricle,
And the clearance gaps in joint and bushing coordinate the position installed to be provided with small boss, and the breach of bushing is blocked into joint during installation
Small boss, bolt insertion bushing and through joint by nut fasten.
In the utility model, the top of breach is globoidal structure.
In the utility model, the thickness of small boss is more than the thickness of auricle.
In the utility model, two small boss are provided with joint.
In the utility model, nut inner sleeve is equipped with packing ring, for adjusting thickness of interlayer, increases bearing area, prevents
Scratch and improve fatigue behaviour；So meet locking requirement, anti-loose structure is simple and reliable, assembly work efficiency high, bushing can be anti-
Use again.
In the utility model, split pin is inserted with nut, promotes bushing to move axially by split pin, Jin Ershi
Now bolt fastening structure is locking.
Beneficial effect：The utility model by optimization bushing and joint design with reach locking purpose and, joint and bushing
Between using gap coordinate, so as to realize the convenient dismounting of bushing, will not make during dismounting joint, bushing be damaged, bushing can make repeatedly
With effectively reducing production cost.
Description of the drawings
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Fig. 2 is the bush structure schematic diagram in preferred embodiment of the present utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to a kind of screw retention device of Fig. 1 ~ Fig. 2, including joint 1, bushing 2, bolt 3, packing ring 4, nut 5, opening
Pin 6, auricle 7, breach 8 and small boss 9；Wherein, auricle 7 is carried on bushing 2, breach 8 is provided with auricle 7, and in joint 1 and lining
The gap of breach 8 of set 2 coordinates the position installed to be provided with small boss 9, and the breach 8 of bushing 2 is blocked into the both sides of joint 1 during installation
Small boss 9, is now coordinated and can be prevented bushing 2 from rotating freely between joint 1 and bushing 2 using gap, the insertion bushing 2 of bolt 3
And through joint 1, subsequently tighten on nut 5, and split pin 6 is inserted in bolt 3, conventional locking measures are taken, make bushing 2
Can not move axially, and then realize the locking of the attachment structure of bolt 3.
In the present embodiment, packing ring 4 installs the inner side of nut 5, for adjusting thickness of interlayer, increases bearing area, prevents from drawing
Injuring improves fatigue behaviour；So meet locking requirement, anti-loose structure is simple and reliable, assembly work efficiency high, bushing 2 can be repeatedly
Use.
In the present embodiment, locking purpose is reached by optimizing bushing 2 and the structure of joint 1, is adopted between joint 1 and bushing 2
Coordinated with gap, realize the convenient dismounting of bushing 2, when dismounting joint 1, bushing 2 will not be damaged, bushing 2 can Reusability.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of without departing from the utility model spirit and scope, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
