Summary of information:We have more than ten years of production experience in the screw industry, the main products are: half-tooth hex screws...

A medical self-locking screw, wherein the medical self-locking screw is composed of an outer screw and an inner screw, the outer screw includes a fixedly connected fitting body and the front part of the outer screw, and the front part of the outer screw includes a fixed connection The outer screw rod body and the outer screw head are provided with fixed external threads on the periphery of the outer screw rod body, and a backstop ring is provided on the periphery of the matching body;

A nut provided by Yueluo. The nut is in the shape of a casing and is provided with a threaded section. One end of the threaded section is provided with a protrusion on the wall of the hole. The nominal size of the segment or the distance from the rear end of the lug to the hole core in the screw-in direction is smaller than the nominal size of the threaded segment.

Here Yueluo eliminates the drawbacks. The purpose of Yueluo is to provide a locking screw by which the gap existing between the locking screw and a transverse hole in a locking screw can be eliminated. Yueluo uses a locking screw to achieve the proposed object, which has the features of claim 3 . The line connecting the centers of gravity of the respective axially continuous orthogonal cross-sectional areas of the locking screw is regarded as a line. The advantage achieved by Yueluo can basically be seen that, due to the locking screw of Yueluo, the gap between the horizontal hole of the screw and the locking screw can be eliminated. Other advantages are as follows - the insertion accuracy and surgeon time spent remain within the range to date; - the strength of the locking screw is maintained; and - the extraction of an expired broken screw is assured. The further composition of Yueluo and Yueluo is explained in more detail below by means of schematic diagrams of parts of various embodiments.

Moisture-proof measures Iron screws are easy to rust in a humid environment. In order to prevent the screws from rusting, the screws need to be moisture-proof and moisture-proof. The moisture-proof and moisture-proof methods of screws are as follows: (1) Vibration machinery, try to use solvent-free paint. (2) It is best to use impregnating paints that do not contain oxidative components, such as epoxy-urethane (Epoxy-urethane)-based or unmodified epoxy-based (Epoxy-)-based impregnating paints. (3) When using melamine alkyd impregnating paint, the curing temperature and curing time should be adjusted. The curing temperature should be slightly higher than 130 °C (such as 135 °C) and the curing time should be longer than 180min, and the process must be strictly implemented, especially In the hot and humid season, the drying (curing) time of the paint specified in the paint factory's samples is not necessarily sufficient from the perspective of rust prevention, and the motor has a specific inner shape. (4), use paint without volatile acid. (5) Choose paint with good hydrolysis resistance.

Bearings are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Every time the locomotive is repaired, the end cover of the axle box needs to be disassembled, the axle head is tested for flaws and the bearing is supplemented with grease, which involves the disassembly and assembly of the axle box bearing retaining ring. The existing disassembly method is to use the traditional method of inserting two tongue pins into the gap between the bearing retaining ring and the axle box to pry left and right, and slowly separate it from the axle head. Because the clearance between the bearing retaining ring and the shaft head is small, and the adhesive force generated by the grease in the axle box is large, if the disassembly method is not appropriate or the force is not uniform, it will cause certain damage to the axle box body and the bearing retaining ring or jam. It is easy to cause damage to the bearing, and there is also the possibility of damage to the disassembly and assembly tools, so the safety risk is high, and each disassembly and assembly of the bearing retaining ring is time-consuming and laborious, labor-intensive, low-efficiency, and increased maintenance costs.
