Abstract
The utility model discloses a bolt, including linking spiral shell head and screw rod as an organic whole, the screw rod on including screw portion, the screw rod afterbody be equipped with a recess, this recess extends to screw flight portion from the bottom surface of screw rod and sets up, this recess is the gradually wide setting of bottom surface to the screw rod from screw flight portion. The utility model discloses bolt has solved the screw thread destruction of causing because of adhesions such as sand and soil, dusts among the prior art, and then improves bolt's life, saves resources for production, is showing reduction repair cost and maintenance duration simultaneously.
Description
Technical field
This utility model relates to a kind of Hardware fitting, refers in particular to bolt or the screw of a kind of screw class.
Background technology
Rainy weather on the way met by existing car, or travels when building site, and the bolt (silk) of car tire can adhesion sandy soil, dust etc..So existing car is being repaired or during maintenance, can there be sandy soil, dust etc. because of the upper adhesion of bolt (silk), not get off because of screw flight portion and nut adhesion, dismounting when causing the bolt (silk) of tire to dismantle.
Utility model content
For problems of the prior art, this utility model provides a kind of bolt.This bolt solves the thread damage caused in prior art, and then the service life of raising bolt because of the adhesion such as sandy soil, dust, saves the resources of production, significantly reduces the cost of repairs and maintenance time simultaneously.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of bolt, including the screw head being connected as a single entity and screw rod, described screw rod includes threaded portion；Described screw rod tail is provided with a groove.This groove is extended to screw flight portion from the bottom surface of screw rod.
Bolt as above a kind of, this groove from screw flight portion to the widest setting in the bottom surface of screw rod.
A kind of bolt as above, this groove is arranged to the bottom surface of screw rod the most deeply from screw flight portion.
Having the beneficial effect that of technique scheme
This utility model bolt is provided with a groove in threaded portion; the sandy soil sticked on screw rod, dust etc. can be rotatably moved in this groove when dismounting; so that sandy soil, dust etc. are discharged, it is achieved nut is in the without hindrance turn of threaded portion, and protects threaded portion from damage.
The groove of this utility model bolt is that extend to bottom surface from screw flight portion the widest is designed the most deeply.This design, when nut turn, can make the discharge that sandy soil, dust etc. are more smooth.
Accompanying drawing explanation
Accompanying drawing described herein is used for providing being further appreciated by of the present utility model, constitutes a part of the present utility model, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the perspective view of this utility model bolt；
Fig. 2 is the use state perspective view of this utility model bolt；
Fig. 3 is that the use state of this utility model bolt looks up structural representation.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
A kind of bolt as Figure 1-3, this bolt can also be a kind of screw, and including the screw head 50 being connected as a single entity and screw rod 10, described screw rod includes threaded portion 20.
Having the problem of sandy soil, dust etc. for solving adhesion on the bolt that prior art is deposited, this utility model bolt is provided with a groove 40 at the afterbody of screw rod 10.This groove 40 upwardly extends setting from the bottom surface 30 of screw rod 10 to the threaded portion 40 of screw rod 10.
As shown in Figure 2,3, described groove 40 communicates with the screw thread of screw rod 10, with when nut 60 turn, the sandy soil sticking in screw portion, dust etc. can be made threadingly to enter groove 40, finally make sandy soil, dust etc. discharge from groove 40.
For making more smooth the discharging from groove 40 such as sandy soil, dust, this utility model groove 40 is set to a skewed slot.As shown in Figure 1, this utility model groove 40 from the threaded portion 20 of screw rod 10 to the widest design in bottom surface 30 of screw rod 10, and this groove 40 designs to the bottom surface 30 of screw rod 10 the most deeply from the threaded portion 20 of screw rod 10, bigger volume is provided, it is ensured that sandy soil, dust etc. are discharged under the extruding of nut 60 smoothly for the sandy soil gradually discharged, dust etc..
Described above illustrate and describes preferred embodiment of the present utility model, as previously mentioned, it is to be understood that this utility model is not limited to form disclosed herein, it is not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and environment, and can be modified by above-mentioned teaching or the technology of association area or knowledge in utility model contemplated scope described herein.And the change that those skilled in the art are carried out and change are without departing from spirit and scope of the present utility model, the most all should be in the protection domain of this utility model claims.
