Problems solved by technology

[0002] The function of the nut currently used is usually to tighten the fixed object. Since there is a gap space when the screw and the nut are screwed together, the gap will gradually increase due to the long-term vibration of the fixed object, causing the problem of gradual loosening, resulting in being fixed. cannot be fully fixed
Especially in the combination and fixation of cpu and heat sink, it is very important. Whether the combination of cpu and heat sink is close or not will affect the heat dissipation efficiency, and then affect the service life of cpu. If the screws are loose, it will definitely cause the cpu and heat sink It cannot be attached tightly to the touch. Based on the demand, there are anti-loosening screws derived from the enhanced fixing design of adding gaskets to the screw structure that increases the occlusal lines. However, due to the structure, the gap space caused by screw occlusal cannot be completely eliminated.

Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] Such as figure 1 As shown, an anti-falling nut includes a screw main body 1, a screw plate surface 10, an internal thread hole 11, a threaded wall surface 12, a threaded surface 13 and a ring groove 14, and one side of the screw main body 1 extends outward to form the internal thread of the screw plate surface 10 The outer edge of the hole 11 is extended with a threaded wall surface 12 with a high convex screw plate surface 10, the inner edge surface of the threaded wall surface 12 is provided with a threaded surface 13 extending continuously with the internal thread hole 11, and the outer edge surface is between the screw plate surface 10 A ring groove 14 is formed. The screw main body 1 is made of plastic.

[0011] One side of the nut body is integrally extended with a disk surface, and a threaded wall surface higher than the disk surface is extended outward from...

Abstract

The invention discloses an improved bolt structure, belonging to the field of bolts. The anti-falling-off nut comprises threads, a nut cap, a threaded rod and a groove, wherein the nut cap and the threaded rod are integrally formed, the groove is arranged on the nut cap, the threads are arranged on the threaded rod, a texture layer is arranged on the outer surface of the nut cap, the nut cap is cylindrical, and the groove is cross-shaped. The anti-falling-off nut has the beneficial effects that the texture layer is arranged on the surface of the nut cap, so that the structure design is reasonable, and the anti-falling-off nut has the skidproof function and is convenient to use.

Description

technical field [0001] The invention relates to a bolt, in particular to an anti-falling nut, which belongs to the field of bolts. Background technique [0002] The function of the nut currently used is usually to tighten the fixed object. Since there is a gap space when the screw and the nut are screwed together, the gap will gradually increase due to the long-term vibration of the fixed object, causing the problem of gradual loosening, resulting in being fixed. cannot be fully fixed. Especially in the combination and fixation of cpu and heat sink, it is very important. Whether the combination of cpu and heat sink is close or not will affect the heat dissipation efficiency, and then affect the service life of cpu. If the screws are loose, it will definitely cause the cpu and heat sink It can’t stick to the touch. Based on the demand, anti-loosening screws are derived. From the enhanced fixing design of adding gaskets to the screw structure that increases the occlusal lines...
