Description

Technical Field

[0001] This utility model relates to the field of anti-loosening screw technology, specifically an anti-loosening screw that is easy to assemble. Background Technology

[0002] Anti-loosening screws are made by thermally spraying a special engineering plastic, primarily nylon, onto the thread teeth. During tightening, this engineering plastic layer is compressed, generating a strong reaction force and friction that prevents the screw from shifting, thus preventing loosening. The secret to anti-loosening screws lies in the internal threads. They look no different from ordinary nuts, but are more durable, extending the lifespan of nuts and bolts. They also perform exceptionally well in vibration tests, effectively preventing loosening and maintaining a tight fit even in environments with frequent vibration. Proper installation and use of anti-loosening screws can also reduce mechanical damage and improve overall reliability and durability.

[0003] However, in order to achieve the loosening effect, the special structure of the thread of the anti-loosening screw makes the assembly of the anti-loosening screw and the screw hole more complicated. In addition, there are other reasons that are not conducive to the screw assembly, such as the head being too large, the screw groove being very deep, and the reluctance to add a radius under the screw head. As a result, the assembly efficiency of anti-loosening screws is low, and there is room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide an anti-loosening screw that is easy to assemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-assemble anti-loosening screw, comprising a screw rod, a screw head fixedly connected to one side of the screw rod, a thread fixedly installed on the outer periphery of the screw rod, and an oil bottle movably connected inside the screw head, the oil bottle communicating with the thread.

[0006] As a further improvement of this utility model: an anti-loosening screw that is easy to assemble, wherein the thread includes a tooth and a flow channel, and the flow channel is spirally downward.

[0007] As a further embodiment of this utility model: an anti-loosening screw that is easy to assemble, wherein the screw head has an inner cavity, one side of the inner cavity is connected to a through hole, an oil bottle is movably connected inside the inner cavity, and the through hole is adapted to a flow channel.

[0008] As a further embodiment of this utility model: an anti-loosening screw that is easy to assemble, wherein an oil pipe is fixedly connected to one side of the oil bottle, and a six-point port is fixedly connected to the end of the oil pipe away from the oil bottle, and the inside of the oil bottle contains lubricating oil.

[0009] As a further improvement of this utility model: an anti-loosening screw that is easy to assemble, wherein the end of the screw rod away from the screw head is fixedly connected to the screw base.

[0010] As a further improvement of this utility model: an anti-loosening screw that is easy to assemble, wherein the thread has a sloping structure.

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

[0012] Because a screw head is fixedly connected to one side of the screw, and threads are fixedly installed on the outer circumference of the screw, and an oil bottle is movably connected inside the screw head, the oil bottle is connected to the threads, and the flow channel is spirally downward. Therefore, before assembling the anti-loosening screw, the oil bottle can be inserted into the inner cavity. After the lubricating oil in the oil bottle drips into the flow channel through the oil pipe, the six-point port, and the through hole, the lubricating oil can be used to wet the threads on the outer circumference of the screw along the spirally downward flow channel, so that the threads can slide smoothly into the screw hole during assembly, which facilitates the assembly of the anti-loosening screw and effectively improves its assembly efficiency.
