Description

[Technical field]

[0001] The utility model relates to the technical field of screws, in particular to the technical field of an anti-slip screw with a chip removal groove. [Background technology]

[0002] Screw refers to screws. Screws are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually fasten objects and machine parts. Screw is a general term for fasteners and a daily colloquialism. Screws are an indispensable industrial necessity in daily life: such as the very small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws and nuts are used in engineering, construction, and bridges; transportation equipment, airplanes, trams, cars, etc. use both large and small screws. Screws have important tasks in industry, and as long as there is industry on the earth, the function of screws will always be important.

[0003] However, when the screws are used for a long time, they are easily corroded by the air, rusted, and easily damaged. In addition, when the machine is repaired and overhauled, the screws are not easy to remove, which will cause a lot of inconvenience to the work.

[0004] In order to solve the problems raised in the background technology, publication number CN203560252U discloses an anti-rust screw, including a nail body and a nail cap, wherein the nail body is provided with a thread; the edge of the nail body is provided with a first oil channel for storing oil; one end of the nail body is connected to the nail cap, and the other end of the nail body is provided with an annular groove; one end of the annular groove is provided with a stopper, and the stopper is fixedly connected to the annular groove, and an oil nozzle is used to add mechanical oil to the third oil channel through the second oil channel, and then the second oil channel is sealed with an oil plug, so that rust can be effectively prevented. However, the structure still has the following shortcomings:

[0005] 1. The screw lacks a chip removal structure. Since a large amount of debris will be generated when the screw is screwed in or out of the workpiece, the debris will be retained in the gap between the screw and the workpiece, and the debris cannot be discharged, which will affect the unstable connection between the screw and the workpiece.

[0006] 2. The screw lacks an anti-slip structure. As the screw is prone to loosening or even sliding between the workpiece during long-term use, the screw may fall off from the workpiece. [Contents of the utility model]

[0007] The purpose of the utility model is to solve the problems in the prior art and to propose an anti-slip screw with a chip groove, which can enable the chips to be discharged outward through the chip groove when the screw is screwed into or out of a workpiece, and the anti-slip structure is added to improve the overall anti-slip performance of the screw.

[0008] To achieve the above-mentioned purpose, the utility model proposes an anti-slip screw with a chip groove, comprising a screw body, a screw head, a screw tail, an external thread, a chip groove, and an anti-slip structure. One end of the screw body is connected to the screw head, and the other end of the screw body is connected to the screw tail. The screw body, the screw head, and the screw tail are an integrated structure. The outer surface of the screw body is provided with an external thread, and the outer wall of the screw body is provided with a plurality of chip grooves, which are used to discharge debris. The bottom of the screw head is symmetrically provided with an anti-slip structure.

[0009] Preferably, a tightening groove adapted to a tightening tool is provided at a middle position on the top of the screw head, and the tightening groove is in a cross-shaped structure.

[0010] Preferably, the outer wall of the screw tail is provided with a plurality of saw teeth, and the saw teeth are in a triangular structure.

[0011] Preferably, the chip groove is in a long strip structure, one end of the chip groove is parallel to the end face of the screw body, and the other end of the chip groove extends to the outer wall of the screw tail.

[0012] Preferably, threaded holes adapted to the anti-slip structure are symmetrically provided on the top of the screw head, the threaded holes are circular in structure, and the threaded holes penetrate the bottom of the screw head.

[0013] Preferably, the anti-slip structure includes a threaded rod, a locking groove, and locking teeth. The threaded rod is rotatably set in the threaded hole and located at the bottom of the screw head. The head of the threaded rod is provided with a locking groove adapted to the auxiliary tool, and the locking groove is a straight-line structure. The tail of the threaded rod is connected with a locking tooth, and the locking tooth is a pointed structure.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model can discharge the debris outward by arranging the chip groove. When the worker inserts the tightening tool into the tightening groove and rotates it to screw the screw body into the workpiece, the screw body will generate a large amount of debris during the screwing process. The debris is accumulated from bottom to top along the bottom of the chip groove through the rotation of the screw body until it conflicts with the bottom of the screw head and falls off, and then the debris is discharged outward along the chip groove, avoiding the debris from being retained in the gap between the screw and the workpiece, thereby improving the stability of the connection between the screw and the workpiece, and solving the problem that the debris cannot be discharged in time, affecting the unstable connection between the screw and the workpiece.

[0016] 2. The utility model can improve the overall anti-slip performance of the screw by providing an anti-slip structure. After the screw is tightened with the workpiece, an auxiliary tool is used to insert it into the locking groove and rotate it, thereby driving the threaded rod to rotate. The threaded rod drives the locking teeth to embed deep inside the workpiece, so that after the screw is screwed into the workpiece, the connection between the screw and the workpiece is tighter, thereby improving the anti-slip performance and solving the problem of the screw being prone to loosening during long-term use.
