Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to a fastening screw provided with a gasket. Background Art

[0002] The main function of screws is to connect two workpieces together to achieve reinforcement. They are common practical tools in work and life.

[0003] For example, the utility model patent disclosed in the publication number CN 219176740 U is a fastening screw, which is provided with a screw head, a screw rod, a hexagonal slot, an inclined slot, a cone head, a chip groove and an inclined portion. When in use, the hexagonal slot can facilitate the use of the screw to fix the workpiece and rotate the screw head. When the screw rod enters the wooden workpiece, the cone head can facilitate the screw rod to enter the interior of the wooden workpiece.

[0004] However, the above-mentioned fastening screws fail to provide a solution to prevent thread slippage, and without the presence of a gasket, the fastening effect of the screw is not obvious, so a fastening screw with a gasket is urgently needed. Utility Model Content

[0005] Based on this, it is necessary to provide a fastening screw with a gasket to address the problem of gasket reinforcement.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fastening screw provided with a gasket, comprising a screw head, the screw head being arranged with eight faces, wherein four faces of the screw head are arranged as narrow faces, and the other four faces of the screw head are arranged as wide faces, mainly used to prevent thread slippage when the screw is tightened, and a cross cap is arranged and fixedly connected on the top of the screw head, providing a second way of tightening the screw.

[0007] In one of the embodiments, anti-skid pads are arranged and fixedly connected on the four narrow surfaces, and an anti-skid groove is arranged at the connection between each narrow surface and the wide surface, so as to more conveniently clamp the screw head when using a wrench to tighten the screw.

[0008] In one of the embodiments, a screw rod is disposed at the bottom of the screw head and fixedly connected thereto, and a plurality of fastening grooves are disposed on the screw rod, which enable the screw to fit more firmly with the object. The screw rod is passed through and provided with fixing grooves in four directions, and the fixing grooves are cross-shaped, so that the fastening screw can be equipped with fixings during the installation process.

[0009] In one of the embodiments, a corkscrew is disposed and fixedly connected to the bottom of the screw rod to facilitate screwing the screw into the object.

[0010] In one of the embodiments, a first gasket and a second gasket are arranged in the middle position of the screw rod. The first gasket and the second gasket can make the screw play a buffering role on the object after being tightened. A soft gasket is arranged and fixedly connected between the first gasket and the second gasket. A plurality of air holes are arranged on the soft gasket to prevent the gasket from breaking when tightened.

[0011] In one of the embodiments, a buffer groove is provided at the bottom of the screw head, and a buffer pad is provided and fixedly connected in the buffer groove. The position of the buffer pad is consistent with the position of the first gasket, so that the gasket will not bulge when it is tightened.

[0012] Compared with the prior art, the fastening screw provided with a gasket in the utility model has the following advantages:

[0013] 1. The fastening screw provides an anti-slip wire solution, which can effectively twist the screw and has a long service life.

[0014] 2. The fastening screw provides a gasket with a reinforcing effect, and compared with the existing gasket solution, it can effectively solve the problem of gasket rupture. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] exist Figure 1-5 In the illustrated embodiment, the utility model provides a technical solution: a fastening screw provided with a gasket, comprising a screw head 1, wherein the screw head 1 is arranged with eight faces, wherein four faces of the screw head 1 are arranged with narrow faces 12, and the other four faces of the screw head 1 are arranged with wide faces 13, which are mainly used to prevent thread slippage when the screw is tightened, and a cross cap 2 is arranged and fixedly connected with the top of the screw head 1, providing a second way of tightening the screw.

[0025] In actual application, compared with the existing fastening screws, anti-skid pads 4 are arranged and fixedly connected on the four narrow surfaces 12, and an anti-skid groove 3 is arranged at the connection between each narrow surface 12 and the wide surface 13, which is used to more conveniently clamp the screw head 1 when using a wrench to tighten the screw.

[0026] Furthermore, a screw rod 6 is provided at the bottom of the screw head 1 and fixedly connected thereto, and a plurality of fastening grooves 5 are provided on the screw rod 6, which can make the screw fit more firmly with the object, and fixing grooves 8 are provided in four directions through the screw rod 6, and the fixing grooves 8 are cross-shaped, so that the fastening screw can be equipped with fixings during the installation process.

[0027] exist Figure 2-5 In the illustrated embodiment, a corkscrew 7 is disposed and fixedly connected to the bottom of the screw rod 6 to facilitate screwing the screw into the object.

[0028] In some embodiments, a first gasket 11 and a second gasket 16 are provided in the middle position of the screw rod 6. The first gasket 11 and the second gasket 16 can enable the screw to buffer the object after being tightened. A soft gasket 9 is provided and fixedly connected between the first gasket 11 and the second gasket 16. The soft gasket 9 is provided with a plurality of air holes 10 to prevent the gasket from breaking when tightened.
