Abstract
The utility model provides a durable screw, which comprises a screw cap, a screw stem and a screw head, wherein the screw head is arranged at the lower end of the screw stem; a connecting piece is arranged between the screw cap and the screw stem; the upper end of the screw cap is provided with a groove; the outer edge of the screw stem is provided with self-tapping threads; the screw head is provided with reinforcing ribs; and the spaces of the reinforcing ribs are equal. The utility model aims to design the durable screw, wherein the reinforcing ribs are arranged at the periphery of the screw head, so that the screw is not broken when being used for fixing a hard object, the service life of the screw is longer, and the durable screw is more durable.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of durable screw.
Background technique
Fastening piece is to be fastenedly connected with and to use very widely class mechanical parts, on various machineries, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., can see fastening piece miscellaneous, its feature is that description is various, the performance purposes is different, and standardization, seriation, unitized kind of degree are also high, therefore also have the people that one class fastening piece of existing NBS is called standard fasteners.
Screw commonly used fixedly the time, generally needs larger power with object, in case strength is excessive, the phenomenon that ruptures of appearance usually causes the fault of machine, has affected the working life of machine.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of durable screw, the peripheral stiffening rib that arranges of screw head makes screw when fixing hard object, is unlikely to fracture, makes the longer service life of screw, and is more durable.
The utility model provides a kind of durable screw, comprise screw cap, screw rod, and the screw head that is arranged on the screw rod lower end, be provided with link between described screw cap and the screw rod, described screw cap upper end is provided with groove, be provided with Thread Forming TF in described screw rod outer rim, described screw head is provided with stiffening rib, and described stiffening rib spacing equates.The purpose of this utility model designs a kind of durable screw, and the peripheral stiffening rib that arranges of screw head makes screw when fixing hard object, be unlikely to fracture, make the longer service life of screw, more durable, this model utility is simple in structure, low cost of manufacture, is a kind of desirable screw.
The utility model discloses a kind of a kind of improvement of durable screw, described stiffening rib is projection outwards, and the thickness of described stiffening rib is 2-5mm.This improved purpose makes screw more durable, can be easier to shoot hard wood, and screw can more easily be fixed on the object, and the thickness of stiffening rib is 4mm after tested, and effect is best.
The utility model discloses a kind of a kind of improvement of durable screw, described stiffening rib is arranged on the periphery of screw head, and described stiffening rib is at least 3.This improved purpose is to strengthen the intensity of screw, makes screw can easily shoot hard wood, prolongs the working life of screw.
The purpose of this utility model designs a kind of durable screw, and the peripheral stiffening rib that arranges of screw head makes screw when fixing hard object, be unlikely to fracture, make the longer service life of screw, more durable, this model utility is simple in structure, low cost of manufacture, is a kind of desirable screw.
