Description
Technical field
The utility model chain bone fixation bolt technical field, it is specifically a kind of excavation chain bone fixation bolt.
Background technology
Excavator, also known as excavating machinery, it is to be excavated to be higher or lower than the material for holding machine side with scraper bowl, and loads haulage vehicle
Or unload to the earthmoving machinery of rickyard.The material that excavator excavates is mainly soil, coal, silt and the soil after pre- pine
And rock.From the point of view of the development of engineering machinery in recent years, the development of excavator is relatively fast, and excavator has become engineering construction
In one of most important engineering machinery.Most important three parameters of excavator:Operating Weight (quality), engine power and scraper bowl
Bucket capacity.
Excavating the connection between chain bone needs to use chain bone fixation bolt, and existing chain bone fixation bolt is easy to come off and beaten
It is sliding.
Utility model content
The purpose of this utility model is to provide a kind of excavation chain bone fixation bolt, to solve the problems of the prior art.
To achieve the above object, the utility model provides following technical scheme：One kind excavates chain bone fixation bolt, including chain
Bone fixation bolt main body, the chain bone fixation bolt body top are provided with screwed hole, screw, the chain are provided with the screwed hole
Bone fixation bolt main body bottom is provided with limited block.
Preferably, set in the middle part of the chain bone fixation bolt main body fluted.
Preferably, screw top both sides are symmetrical arranged jagged, and the limited block both sides are symmetrical arranged as breach.
Preferably, the screw is identical with limited block diameter, and the diameter of screw and limited block is more than chain bone fixation bolt main body
Diameter.
Preferably, the chain bone fixation bolt main body is arranged to integral structure with limited block.
Compared with prior art, the beneficial effects of the utility model are：By setting screw, screw is twisted the utility model
Do not loosen afterwards non-slip, avoid the problem of bucket tooth pin comes off in construction operation, chain bone fixation bolt main body is set with limited block
For integral type structure so that the structure of the chain bone fixation bolt is more stable, prevents chain bone fixation bolt breaking releasing, and the device knot
Structure is simple, use easy to spread.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model；
Fig. 2 is the top view that the utility model bolt is twisted.
In figure：1- screws, 2- chain bone fixation bolts main body, 3- limited blocks, 4- screwed holes, 5- grooves, 6- breach.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~2, in the utility model embodiment, one kind excavates chain bone fixation bolt, including chain bone fixation bolt master
Body 2, the top of chain bone fixation bolt main body 2 are provided with screwed hole 4, screw 1, the bottom of chain bone fixation bolt main body 2 are provided with screwed hole 4
Be provided with limited block 3, chain bone fixation bolt main body 2 inserted in the connecting hole of chain bone, screw 1 do not loosened after being twisted it is non-slip,
The problem of bucket tooth pin comes off is avoided in construction operation, the middle part of chain bone fixation bolt main body 2 sets fluted 5, the top both sides of screw 1
It is symmetrical arranged jagged 6, the both sides of limited block 3 are symmetrical arranged as breach 6, and screw 1 is identical with the diameter of limited block 3, screw 1 and limit
The diameter of position block 3 is more than the diameter of chain bone fixation bolt main body 2, can play spacing effect, chain bone fixation bolt main body 2 and limited block
3 are arranged to integral structure so that the structure of the chain bone fixation bolt is more stable, prevents chain bone fixation bolt breaking releasing.
Operation principle of the present utility model is：Will excavate chain bone between by repacking put connection, by chain bone fixation bolt master
Body 2 is inserted in the connecting hole of chain bone, and screw 1 does not loosen non-slip after being twisted, avoid what bucket tooth pin came off in construction operation
Problem, chain bone fixation bolt main body 2 are arranged to integral structure with limited block 3 so that and the structure of the chain bone fixation bolt is more stable,
Prevent chain bone fixation bolt breaking releasing.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
