Description

Technical Field

[0001] The utility model relates to the technical field of bolt assemblies, in particular to a high-strength internal plum blossom flange precision screw. Background Art

[0002] Screws are commonly found in machinery, electrical appliances and buildings. They are generally made of metal or plastic, cylindrical in shape, and have concave and convex grooves on the surface called threads. The main function of screws is to connect two objects or fix the position of an object. Screws can usually be removed or re-tightened at will without losing their efficiency.

[0003] A flange screw refers to a screw with a larger diameter disk under the screw head. The screw head of the cylindrical flange screw is a cylinder with a cross-shaped slot on the surface of the cylinder. Therefore, the staff can use a screwdriver to install and remove the screw as a whole. Therefore, the use range of the cylindrical flange screw is also relatively wide. Since the screw head of the cylindrical flange screw is a cylinder, a wrench cannot be used to install and remove the screw as a whole. Therefore, the staff can only install and remove the screw as a whole by using a screwdriver. The screw has a single tool to match when in use, and the applicable scope of the screw is small. Since the disassembly tools used by the staff are various, it is not conducive for the staff to install and remove the screw as a whole by using different tools. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a high-strength internal plum blossom flange precision screw, which can solve the problem that the tool that matches the screw is single when it is used, the application range of the screw is small, and since the disassembly tools used by the staff are various, it is not conducive to the staff to install and disassemble the screw as a whole by using different tools.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a high-strength internal plum blossom flange precision screw, comprising a screw rod, a front end surface of the screw rod being provided with a screw groove, a rear end surface of the screw rod being provided with an annular groove, the interior of the annular groove being fixedly connected with reinforcing ribs for increasing strength, and the reinforcing ribs being distributed equidistantly in a ring shape at the rear end of the screw rod.

[0006] Preferably, a hexagonal prism for rotation is fixedly connected to the rear end of the screw rod, and a through hole for disassembly is provided on the surface of the hexagonal prism.

[0007] Preferably, a plum blossom slot for installation and disassembly is formed at one end of the hexagonal prism away from the screw rod.

[0008] Preferably, a spare plum blossom clamping block is slidably connected inside the plum blossom clamping slot.

[0009] Preferably, a cross-shaped card slot for installation and disassembly is provided on the rear surface of the plum blossom card block.

[0010] Preferably, an end of the hexagonal prism close to the screw rod is fixedly connected with an arc-shaped blade for providing a pressing force, and the arc-shaped blades are distributed equidistantly in a ring shape around the center of the hexagonal prism.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) With this high-strength internal plum-shaped flange precision screw, workers can insert a steel wire into the internal rotating hexagonal prism of the through hole, thereby driving the screw rod to rotate to complete disassembly and installation. In the process of disassembling and installing the screw rod, workers can use a steel wire, a cross screwdriver, a plum-shaped screwdriver, and a wrench to rotate the screw rod to complete disassembly and installation. There are four tools that match the screw when in use, which increases the application range of the screw and makes it more convenient for workers to install and disassemble the screw as a whole using different tools.

[0013] (2) With this high-strength internal plum-shaped flange precision screw, a worker rotates the screw rod, and the screw rod rotates and enters the interior of the screw hole through the screw groove on the surface, thereby fixing the object. During the process of fixing the object, the screw rod is reinforced as a whole by multiple reinforcing ribs to prevent the screw rod from bending during rotation, thereby improving the stability of the screw rod in fixing the object.

[0014] (3) In the process of installing the high-strength internal plum blossom flange precision screw, the hexagonal prism rotates and drives the screw rod. The hexagonal prism rotates and drives the curved blades on the surface to rotate and squeeze on the surface of the object, and then the curved blades replace the screw gasket. The staff no longer needs to insert the gasket into the surface of the screw rod, thereby improving the efficiency of the staff in installing the screw rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Under normal circumstances, the staff can insert the plum screwdriver into the inside of the plum card slot 7 to rotate the hexagonal prism 5 and the screw rod 1 to complete the disassembly and installation. When the staff forgets to carry the plum screwdriver, since the surface of the hexagonal prism 5 is six planes, the staff can clamp two of the planes of the hexagonal prism 5 with a wrench to rotate it, thereby completing the disassembly and installation of the screw rod 1. Among them, after the staff slides the plum card block 8 into the inside of the plum card slot 7, since the surface of the plum card block 8 is provided with a cross-shaped card slot 9, the staff can use the cross-shaped screwdriver to simultaneously rotate the plum card block 8 and the hexagonal prism 5, thereby driving the screw rod 1 to rotate to complete the disassembly and installation. Finally, the staff can insert the steel wire into the inside of the through hole 6 to rotate the hexagonal prism 5, thereby driving the screw rod 1 to rotate to complete the disassembly and installation. In summary, in the process of disassembling and installing the screw rod 1, the staff can use a total of four methods, namely, steel wire, cross screwdriver, plum screwdriver, and wrench, to rotate the screw rod 1 to complete the disassembly and installation.

When the staff forgets to carry the plum blossom screwdriver, since the surface of the hexagonal prism 5 is six planes, the staff can use a wrench to clamp two of the planes of the hexagonal prism 5 and rotate it, thereby completing the disassembly and installation of the screw rod 1. After the staff slides the plum blossom block 8 into the inside of the plum blossom slot 7, since the surface of the plum blossom block 8 is provided with a cross-shaped slot 9, the staff can use a cross-shaped screwdriver to simultaneously rotate the plum blossom block 8 and the hexagonal prism 5, thereby driving the screw rod 1 to rotate to complete the disassembly and installation. Finally, the staff can insert a steel wire into the through hole 6 to rotate the hexagonal prism 5, thereby driving the screw rod 1 to rotate to complete the disassembly and installation. In summary, during the process of disassembling and installing the screw rod 1, the staff can use a total of four methods, namely, steel wire, cross screwdriver, plum blossom screwdriver, and wrench, to rotate the screw rod 1 to complete the disassembly and installation.
