Abstract
The utility model comprises a kind of anti-skid screw, the screw rod including nut and be connected with nut, described nut surface is circumferentially with many convex tendons along nut center, and described convex tendon can be divided into thick convex tendon and thin convex tendon according to thickness, and described thick convex tendon and thin convex tendon interval are arranged.After surface is provided with convex tendon, people can be made first screw to be pressed screw place when nut is stained with water more easily, and the different convex tendon interval of thickness arrange frictional force when can increase pressing greatly.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of anti-skid screw.
Background technique
Screw is the fastening piece for mounting article, and it uses comparatively extensive, usually screw is mounted to fixation and with in the screw of fixture articles, just can implements to fix.Spun by screw thread between screw and screw, because screw can be applied in a variety of operating mode, more particularly be exposed to outdoor screw, run into rain or other screws are stained with in the situation of water time, just be difficult to free-hand by screws tighten in screw, so, anti-skid screw is just applied to when screw is stained with water, increase the frictional force of screw, user is allowed better to use screw, but traditional anti-skid screw is provided with many convex tendons at nut shade place, frictional force when utilizing convex tendon increase to rotate, but first need nut to be pressed into a segment distance in hole when usually screw being fixed in screw, but because water is stained with nut in pressing process, there will be frictional force to reduce, nut pressing is difficult to, causing cannot normal Practical screw.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of fastening piece, and especially one tightens up effective, easy to operate, the simple anti-skid screw of structure.
For solving the problems of the technologies described above, the screw rod that the utility model includes nut and is connected with nut, described nut surface is circumferentially with many convex tendons along nut center, and described convex tendon can be divided into thick convex tendon and thin convex tendon according to thickness, and described thick convex tendon and thin convex tendon interval are arranged.
After have employed said structure, because existing anti-skid screw is all arrange convex tendon at nut shade place and do not arrange at nut surface place, after surface is provided with convex tendon, people can be made first screw to be pressed screw place when nut is stained with water more easily, and the different convex tendon interval of thickness arrange frictional force when can increase pressing greatly.
As further improvement of the utility model, described nut surface is circumferentially with multiple osculum along nut center, and described osculum is circular setting and the setting of this osculum interval, and the span of each osculum described is equal.
After have employed said structure, the water that can make to be deposited in nut surface that arranges of osculum is discharged fast, avoid because nut surface is put aside by water and screw cannot be used, and water vent prevent to some extent screw because water is etched and corrodes fast.
As further improvement of the utility model, described nut shade place is circumferentially with four grooves, and the size of described groove arranges the nut can rotating screw of being available for users to hold with a firm grip.
After have employed said structure, groove be more convenient for user free-hand by screws tighten to screw place.
Accompanying drawing explanation
figure 1 shows that this anti-skid screw side schematic view;
figure 2 shows that nut front view.
Embodiment
As shown in Fig. 1 Fig. 2, the screw rod (2) that this anti-skid screw includes nut (1) and is connected with nut (1), described nut (1) surface is circumferentially with many convex tendons (3) along nut (1) center, described convex tendon (3) can be divided into thick convex tendon (4) and thin convex tendon (5) according to thickness, and described thick convex tendon (4) and thin convex tendon (5) interval are arranged.Described nut (1) surface is circumferentially with multiple osculum (6) along nut (1) center, and described osculum (6) is circular setting and the setting of this osculum (6) interval, and the span of described each osculum (6) is equal.Described nut shade place is circumferentially with four grooves (7), and the size of described groove (7) arranges the nut (1) can rotating screw of being available for users to hold with a firm grip.Groove (7) be more convenient for user free-hand by screws tighten to screw place.
Because existing anti-skid screw is all arrange convex tendon at nut shade place and do not arrange at nut surface place, after surface is provided with convex tendon, people can be made first screw to be pressed screw place when nut is stained with water more easily, and the different convex tendon interval of thickness arrange frictional force when can increase pressing greatly.The water that can make to be deposited in nut surface that arranges of osculum is discharged fast, avoids because nut surface is put aside by water and cannot use screw, and water vent prevent to some extent screw because water is etched and corrodes fast.
Claims (3)
1. an anti-skid screw, the screw rod including nut and be connected with nut, it is characterized in that: described nut surface is circumferentially with many convex tendons along nut center, described convex tendon can be divided into thick convex tendon and thin convex tendon according to thickness, and described thick convex tendon and thin convex tendon interval are arranged.
2. anti-skid screw according to claim 1, is characterized in that: described nut surface is circumferentially with multiple osculum along nut center, and described osculum is circular setting and the setting of this osculum interval, and the span of each osculum described is equal.
