Abstract
The utility model discloses a kind of band locking teeth turret head screw assemblies, include head of screw and washer, and washer is equipped with the centre bore passed through for head of screw, it is characterised in that：The bottom support surface setting 24 of the head of screw is along tooth, the washer is spill circle, the plane of spill circle is in cubic shape, and plane is equipped with match with head of screw bottom support surface 24 along tooth, the washer outer edge is provided with eight raised locking teeths, and the direction of raised locking teeth is vertical with the radial direction of washer.The utility model solves the problems, such as to have reached desired anti-loosing effect since single locking design causes locking functions bad in the past.
Description
Technical field
Improvement invention more particularly to a kind of band locking teeth turret head group the utility model is related to auto parts machinery tooling field
Close the improvement invention of screw.
Background technology
A screw on automobile chair currently on the market, locking functions are always the problem continuously improved.It is most of
Cooperation be to increase by a lower tooth washer on the basis of screw.Either locking teeth is done on the supporting surface of screw.It is and this single
Anti-loosing effect it is not ideal.So based on this reason, our company has developed this screw assemblies with locking teeth.
Utility model content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of rational in infrastructure, anti-
The good band locking teeth turret head screw assemblies of loose effect.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize：This kind is with locking
Tooth turret head screw assemblies include head of screw and washer, and washer is equipped with the centre bore passed through for head of screw, and feature exists
In：The bottom support surface setting 24 of the head of screw is along tooth, and the washer is spill circle, and the plane of spill circle is in cubic shape,
And plane be equipped with match with head of screw bottom support surface 24 along tooth, there is provided eight protrusions to prevent for the washer outer edge
Loose tooth, the direction of raised locking teeth are vertical with the radial direction of washer.
The beneficial effects of the utility model are improved band locking teeth turret head screw assemblies, are solved in the past due to list
The problem that one locking design causes locking functions bad, has reached desired anti-loosing effect.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the utility model head of screw bottom support surface structure chart.
Fig. 3 is the Facad structure figure of the utility model washer.
Fig. 4 is the backside structure figure of the utility model washer.
Specific embodiment
Attached drawing illustrates the structure of the utility model, further illustrates it in relation to details in conjunction with attached drawing below.The band is anti-
Loose 3 turret head screw assemblies of tooth, include head of screw 1 and washer 2, and washer 2 is equipped with the centre bore passed through for head of screw 1, institute
The bottom support surface setting 24 of head of screw 1 is stated along tooth, the washer 2 is spill circle, and the plane of spill circle is in cubic shape, and flat
Face is equipped with match with 1 bottom support surface of head of screw 24 along tooth, and it is locking that 2 outer edge of washer is provided with eight protrusions
Tooth 3, the direction of raised locking teeth 3 are vertical with the radial direction of washer 2.
Utility model works principle, during head of screw 1 is threaded into, locking teeth 3 on 1 bottom support surface of head of screw with
3 automatic aligning of locking teeth in 2 plane of washer is made uniform, and head of screw 1 firmly meshes together with washer 2.Meanwhile outside washer 2
Eight protrusions at edge, which are deeply embedded into, in fastener, is reached the tight effect of fastening.
In conclusion the above is only the preferred embodiments of the present utility model only, it is not intended to limit the utility model
Protection domain.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all wrap
Containing being within the protection scope of the utility model.
