Abstract
The invention discloses an antiskid screw which comprises a nut and a screw rod. The nut is located at one end of the screw rod, and the upper end face of the nut is provided with a driving groove. The driving groove is a cross-shaped groove or a linear groove, and threads are arranged on the screw rod. A driving hole is formed in the lateral face of the nut. The nut is cylindrical, and the height of the lateral face of the nut is 25m-35m. The driving hole is a round through hole. The diameter of the round driving hole is 10mm-15mm, and the shortest distance between the driving hole and the bottom of the driving groove is 2mm-3mm. The depth of the driving groove is 3mm-5mm. The antiskid screw solves the problem that in the prior art, when a screwdriver is put into the driving groove to rotate, the screwdriver is extremely prone to skidding, and once the driving groove is abraded, the screwdriver cannot be used for rotating. The antiskid screw is simple in structure and capable of effectively reducing abrasion of the driving groove.
Description
Technical field
The present invention relates to a kind of fastening connection piece, especially relate to a kind of screw with anti-slip function.
Background technique
Screw is a kind of fastening piece of commonly using, and current screw consists of the screw rod of nut and nut below, in the upper-end surface of nut, is provided with driver slot, on screw rod, be provided with screw thread, during installation, by screw-driver, act in driver slot, to screw rod, provide rotating force, thereby screw in target object.The driver slot of existing screw is all the grooves to lower recess that arrange at nut upper surface, relation due to nut thickness, the degree of depth of driver slot is limited, when screw-driver being put into driver slot be rotated, very easily skid, once and driver slot be worn, can not recycle screw-driver rotation, it has just lost original effectiveness, has reduced the working life of screw.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and a kind of Antiskid screw is provided, and can avoid coping screw to rotate " cross " driver slot or " word " driver slot too tight and on wear nut.
The technical solution used in the present invention is: a kind of Antiskid screw, comprise nut and screw rod, and described nut is positioned at one end of described screw rod, and the upper-end surface of described nut is provided with a driver slot; It is characterized in that: described driver slot is " cross " connected in star or " word " connected in star, described screw rod is provided with screw thread, on the side of described nut, is provided with drive hole.
Aforesaid a kind of Antiskid screw, is characterized in that: described nut is cylindrical body, and the side height of described nut is 25mm-35mm.
Aforesaid a kind of Antiskid screw, is characterized in that: described drive hole is manhole, and the diameter in described circular drives hole is 10mm-15mm.
Aforesaid a kind of Antiskid screw, is characterized in that: the nearest distance in described drive hole and driver slot bottom is 2mm-3mm.
Aforesaid a kind of Antiskid screw, is characterized in that: the degree of depth of described driver slot is 3mm-5mm.
By technique scheme, the invention has the beneficial effects as follows: the present invention is provided with drive hole on the side of nut, can too tightly be difficult to turn when screw, and when can wear and tear again this driver slot by " cross " or " word " driver slot on stubborn nut, by this drive hole, carry out rotation screw, can protect driver slot not to be damaged, extend the working life of driver slot; Simultaneously the height of nut of the present invention, the distance from bottom of the degree of depth of the diameter of drive hole, driver slot and drive hole and driver slot can be by reasonable arrangement the position relationship between them, prevent that drive hole from overlapping with driver slot, cause use inconvenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Antiskid screw of the present invention.
Fig. 2 is the use view of a kind of Antiskid screw of the present invention.
Embodiment
For further setting forth the present invention, reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, its embodiment, structure, feature and effect thereof to proposing according to the present invention, be described in detail as follows.
Shown in Fig. 1, a kind of Antiskid screw, comprises nut 1 and screw rod 2, and described nut 1 is positioned at one end of screw rod 2, and the upper-end surface of described nut 1 is provided with a driver slot 3; Described driver slot 3 is " cross " connected in star or " word " connected in star, and described screw rod 2 is provided with screw thread 5, is provided with drive hole 4 on the side of described nut 1.Described nut 1 is cylindrical body, and the side height of described nut 1 is 25mm-35mm; Described drive hole 4 is manhole, and the diameter of described drive hole 4 is 10mm-15mm; The nearest distance in bottom of described drive hole 4 and described driver slot 3 is 2mm-3mm; The degree of depth of described driver slot is 3mm-5mm.
Shown in Fig. 2, the present invention in use, when screw is when too being tightly difficult to turn, can insert drive hole 4 with screw-driver or the iron that is less than drive hole 4 and rotate screw thread 5, can according to circumstances impose the power of A direction or B direction.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
