Description

Technical Field

[0001] The utility model relates to the technical field of fixing parts, in particular to an invisible magnetic opening anti-loosening nut kit. Background Technique

[0002] A nut is a screw cap that is screwed together with a bolt or screw rod to play a fastening role. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). Nuts are parts that tightly connect mechanical equipment. Through the internal thread, nuts and bolts of the same specification can be connected together. For example, a nut of M4-P0.7 can only be connected with a bolt of the M4-P0.7 series (in the nut, M4 means the inner diameter of the nut is about 4 mm, and 0.7 means the distance between two thread teeth is 0.7 mm); the same is true for American-made products. For example, a nut of 1 / 4-20 can only be matched with a screw rod of 1 / 4-20 (1 / 4 means the inner diameter of the nut is about 0.25 inches, and 20 means that there are 20 teeth in every inch). The DISC-LOCK anti-loosening nut is composed of two parts, each part has staggered cams. Due to the slope angle of the internal wedge design being greater than the nut angle of the bolt, this combination tightly bites into a whole. When vibration occurs, the protruding parts of the DISC-LOCK anti-loosening nut move relative to each other, generating a lifting tension, thereby achieving a perfect anti-loosening effect.

[0003] The application number is CN201820970684.1, which discloses a bolt and nut kit to solve the problem that the specifications of bolts and nuts cannot be fully matched with the part mounting holes in actual applications. The bolt and nut kit includes a bolt and a nut. The bolt includes a screw rod, a bolt head, and an outer sleeve. There is an external thread on the whole screw rod, and the diameter of the screw rod gradually increases towards the end of the bolt head; the inner wall of the outer sleeve is provided with an internal thread, and the outer wall is provided with an external thread. The outer sleeve is rotationally connected to the screw rod through the internal thread. The end of the outer sleeve facing away from the bolt head is provided with a plurality of longitudinal cuts; the nut includes a shell and a clamping layer. The inner wall of the clamping layer is provided with a thread. The clamping layer is composed of a plurality of fan-shaped blocks with the same shape. The shell is sleeved outside the clamping layer, and the shell and the clamping layer are connected by a spring.

[0004] Although the above-mentioned utility model has a nut including a shell and a clamping layer, the inner wall of the clamping layer is provided with a thread, the clamping layer is composed of a plurality of fan-shaped blocks with the same shape, and the shell is sleeved outside the clamping layer and the shell and the clamping layer are connected by a spring, there are still deficiencies. When the device is used, rusting and jamming may occur due to long-term use, which reduces the use effect.

[0005] Therefore, it is necessary to replace the bolts in the device with lubricating bolt assemblies, so that when using the device for fixed connection, good lubrication effect can be achieved through the internal lubricating parts. Through the provided lubrication work, the use can be made smoother and the noise caused by rust can be avoided. Summary of the Invention
