TECHNICAL FIELD

[0001] The present application relates to the technical field of nut manufacturing, in particular to a side locking ceramic nut. BACKGROUND

[0002] The nut is also called a nut, which is a fixing tool with a hole in the center and a thread on the inner side of the hole, often used with a screw of the same size to fix the relevant joint parts.

[0003] At present, in daily mechanical manufacturing, the commonly used nuts are mostly metal nuts, but for some special nut use scenarios in special environments, such as acidic or alkaline environments, the metal nuts are prone to corrosion, causing the nut used to fasten the screw shaft to loosen with the screw shaft, affecting the fastening effect of the nut.

[0004] The ceramic nut, as the name implies, is a screw product made of silicon nitride, which has relatively stable physical stability and chemical stability. The physical stability is mainly manifested in high and low temperature resistance, insulation, magnetic resistance, wear resistance, etc. The chemical stability is mainly manifested in corrosion resistance and oxidation resistance. Therefore, when the ceramic nut is used to connect with the screw shaft, the ceramic nut is not prone to corrosion, and the ceramic nut and the screw shaft are not prone to loosening.

[0005] However, this ceramic nut also has some defects, for example, the ceramic nut and the screw shaft are hard connected, and in the use process of the screw shaft and the ceramic nut, the ceramic nut and the screw shaft are loosened under the action of stress, causing the tension between the screw shaft and the ceramic nut to fluctuate, affecting the fastening effect of the used ceramic nut.

[0011] Meanwhile, the pressing groove is internally movably installed with a pressing pipe for realizing the pressing function when the side locking ceramic nut is connected with the screw shaft, and improving the firmness of the connection between the side locking ceramic nut and the screw shaft.

[0012] As a further scheme of the present application, the plate surface is further provided with arc-shaped baffles which are annularly distributed on the plate surface.

[0013] As a further scheme of the present application, the two sides of the pressing pipe are provided with arc-shaped baffles which are bevels; meanwhile, the pressing pipe is internally provided with a movable cavity, the inner wall of the movable cavity is provided at the upper end with a compression spring, one end of the compression spring is fixedly installed on the inner wall of the movable cavity, the other end of the compression spring is provided with a lock ring, and the lock ring is movably installed with a rolling ball inside.
