Abstract
The utility model discloses a kind of guide rail screw assemblies for optimizing torsion, pass through the step structure of screw head, increase the surface area between screw terminal and the moulding for coating screw terminal, increase cladding power, the step structure for the screw head that diameter is gradually reduced simultaneously also enhances the overall stability of screw, so that the torque of screw increases, avoiding guide rail moulding, the guide rail as caused by torque screw is insufficient falls off problem after mounting, solves the problems such as abnormal sound and stuck glass.
Description
Technical field
The utility model relates to fastener areas, and in particular to a kind of guide rail screw assembly for optimizing torsion.
Background technique
For the guide groove of automobile door glass lifting, the problems such as Assembly stability and wind of product are made an uproar, is urgently to be resolved.In existing skill
In art, torque of the ironware screw in guide rail is insufficient after guide rail installation or torque reduces, and will lead to glass door in the process of lifting
In remove ironware screw and plastic guide rail so that assembly failure, generate abnormal sound, the problems such as glass is stuck.How screw is promoted
Torque between guide rail screw is the main target of technical staff.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of guide rail screw group for optimizing torsion
Part, it improves torsion and binding force between screw piece and guide rail.
Realize above-mentioned purpose a kind of technical solution be: it is a kind of optimize torsion guide rail screw assembly, including moulding and
Screw piece；
The screw piece includes screw head and screw rod, and the screw head is equipped at least two step structures, for any two
The adjacent step structure, the diameter of the step structure far from the screw rod are greater than the step close to the screw rod
The diameter of structure；
The moulding is integrally formed in injection mold with the screw piece, and the moulding coats the screw head, institute
It states screw rod and stretches out the moulding.
Further, the interconnecting piece of the moulding and the step structure near the screw rod of the screw head is opened
Equipped with link slot.
A kind of guide rail screw assembly of optimization torsion of the utility model increases spiral shell by the step structure of screw head
Surface area between silk head and the moulding for coating screw terminal, increases cladding power, while the step of screw head that diameter is gradually reduced
Structure also enhances the overall stability of screw so that the torque of screw increases, avoid guide rail moulding after mounting due to
Guide rail caused by torque screw is insufficient falls off problem, solves the problems such as abnormal sound and stuck glass.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the guide rail screw assembly of optimization torsion of the utility model.
Specific embodiment
In order to preferably understand the technical solution of the utility model, below by specifically embodiment and combine
Attached drawing is described in detail:
Referring to Fig. 1, a kind of guide rail screw assembly of optimization torsion of the utility model, including moulding 2 and screw piece
1。
Screw piece 1 includes screw head 11 and screw rod 12, and screw head 11 is equipped at least two step structures, for any two phase
Adjacent step structure, the diameter of the step structure far from screw rod are greater than the diameter of the step structure close to screw rod.In the present embodiment
In use two step structures, i.e. first step structure 111 and second step structure 112, the diameter of second step structure 112
Greater than first step structure 111.
Moulding 2 is integrally formed in injection mold with screw piece 1, so that injected plastics material sufficiently coats the first of screw head 11
Step structure 111 and second step structure 112, screw rod 12 stretch out moulding.The design of such structure, increase moulding 2 with
The contact area of screw head 11 increases clad surface power, has prompted the stability of screw piece 1, increases the torque of ironware screw,
Preventing guide rail, torque is insufficient after mounting, and guide rail is caused to fall off, and solves abnormal sound, the problems such as glass is stuck.
Moulding 2 and the interconnecting piece of first step structure 111 offer link slot 3, enable screw rod 12 more complete
It outside being exposed to, prevents injection molding material from covering to screw rod 12, guarantees the connection effect of screw piece 1.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will all be fallen in the Claims scope of the utility model.
Claims (2)
1. a kind of guide rail screw assembly for optimizing torsion, including moulding and screw piece, it is characterised in that:
The screw piece includes screw head and screw rod, and the screw head is equipped at least two step structures, adjacent for any two
