Service HotlineA 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;
The existing structure is found in the practical application experience that there are still the following problems and drawbacks: the screw structure and the screw space are combined with each other in a complementary manner, so they can provide a higher torque value, however, not every workpiece. The combination requires a high torque value, so it often results in excess quality. Although the price of the screw is low, if it can change the unchanging structure of the traditional screw, it can provide a technical means to simplify (change) the process. The effect of improving production capacity and convenience of use is indeed a technical bottleneck that the relevant industry should break through.
In order to meet the requirements of anti-loosening bolts of parts with small surface hardness such as plastic parts, Yueluo provides a spring washer and the installation structure of the spring washer, which can effectively reduce the damage of the spring washer to the surface of the parts. And meet the anti-loosening effect of the spring washer. The technical solution provided by Yueluo is a spring washer, which includes a washer body with at least two raised claws on the washer body
Guangdong Yueluo Hardware Industry Co., Ltd. has a simple structure, low processing difficulty, and convenient riveting. The whole pin has the same diameter except for the annular groove. The drawn wire can be directly used, which saves the cost of materials and machining costs, and improves the production speed and efficiency. The structure does not require high machining accuracy of the hole, which can effectively reduce the machining cost and the rework rate of the parts.
Axle card is a kind of hole-to-hole movement installed on a slotted shaft and used as a fixed component. The inner diameter of this type of retaining ring is slightly smaller than the diameter of the assembly shaft. Application No. 201621153710.9 discloses a shaft card assembly device, including a feeding mechanism, a material distribution mechanism, a material reclaiming mechanism and an assembling mechanism. The feeding mechanism is connected with the feeding mechanism. The reclaiming mechanism includes a reclaiming tool and a servo system for driving the movement of the reclaiming tool. One end of the reclaiming tool is provided with a c-shaped opening, and an incision connected with the c-shaped opening is provided. The assembling mechanism includes a carrier for fixing the parts to be loaded and a turntable, and the carrier is mounted on the turntable. In the above shaft card assembly device, after the feeding mechanism completes the feeding, the material distribution mechanism separates the shaft card to a specific position with a fixed attitude, and then the private server drives the reclaiming tool to clamp the shaft card and assemble it to the pre-fixed by the assembly mechanism. on the fitting. During the assembly process, the manual workload is small, the efficiency is high, and the labor intensity is small. At the same time, the c-shaped opening and the cutout at the end of the reclaiming tool are designed to effectively form an elastic force to clamp the clamping shaft card and absorb the assembly process. The resulting outward deformation force avoids the plastic deformation of the shaft card due to the large external force.
