Description
Technical field
It the utility model is related to a kind of brand-new bolt structure.
Background technology
Screw primarily serves fixation, existing automobile using screw bag as one of parts essential on automobile
Include screw rod and head, the thread pitch on screw rod is equal, when in use, screw directly is screwed in into screw, so as to by two zero
Part is fixedly connected, but existing screw has following defect, on the one hand, the easy fracture when screw screws in；On the other hand, in screw
After screwing, when that parts need to be changed or repaired, it is necessary to which screw is screwed out, but the outer spiral shell on the screw after screwing in
Line becomes big with the internal thread resistance in screw, or after water inlet is got rusty, it is difficult to screw is screwed out, it is firmly excessive to also result in
Screw extraction, so as to be split to parts.
Therefore those skilled in the art are directed to developing a kind of a kind of brand-new spiral shell that can effectively solve the problem that screw and screw out problem
Pin structure.
Utility model content
In view of the drawbacks described above of prior art, technical problem to be solved in the utility model, which is to provide one kind, to be had
Effect solves a kind of brand-new bolt structure that screw screws out problem.
To achieve the above object, the utility model provides a kind of brand-new bolt structure, including bar portion, the cross section of bar portion
In cylinder, the upper end of bar portion is provided with cruciform groove, and the lower end of bar portion is provided with introduction part, opened on the outer circle wall of bar portion
Provided with several grooves, each groove extends to the lower end of bar portion from the upper end of bar portion.
For the ease of screw rod is screwed in screw, the upper end of introduction part and the bottom of bar portion connect, the cross section of introduction part
Taper into from top to bottom.
In order to reduce manufacturing cost while screw-in is easily facilitated, the maximum gauge of introduction part is less than the diameter of bar portion.
Solves anti-jamming problem in order to significantly more efficient, the rounded array of groove is opened on outer circle wall.
The number of groove is eight, on the one hand the structure can improve and solve the problems, such as anti-sticking, on the other hand, reduces manufacture
Ensure the firmness of structure while cost.
In order to further improve the firmness of screw rod, increase the service life, several reinforcements are provided with each groove.
In order to when rotated, prevent screw extraction and screw rod self-deformation when using permanent or rotation, in adjacent grooves
Reinforcement shift to install.
For more easily rotation and raising firmness, preferably, each reinforcement is obliquely installed.
Preferably, the setting that each reinforcement is evenly distributed from top to bottom is in a groove.
In order to be easy to manufacture cost-effective while, bar portion, groove and reinforcement are formed in one structure.
The beneficial effects of the utility model are：The utility model solves the technical problem that screw is difficult to screw out, effectively
Screw is prevented to be broken because stuck in screw, having reduces manufacturing cost, simple in construction and increase the service life etc. beneficial
Effect.
