Service HotlineThe anti-rotation T-bolt includes a screw rod and a head. An anti-rotation protrusion is designed at the connection between the head and the screw. The cross-section of the anti-rotation protrusion is a square corner with the screw radius as the side length. One anti-rotation protruding shoot can be designed, or two can be designed. In order to ensure the uniform force of the bolt, two are designed.
Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation. They are suitable for parts with frequent assembly and disassembly. Quick and easy automatic selection of washers is included, but the anti-loosening ability of spring washers is very low! Especially in European and American countries that require high reliability, the adoption rate is extremely low, especially the important load-bearing structural connection parts have long been abandoned. Our country still has some applications in the military industry, but it has been improved to stainless steel. Steel spring washers have long been banned in CASC! It is also said to be very unsafe, because there are two reasons: 1 is circle rise and 2 is hydrogen embrittlement.
The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are: in Guangdong Yueluo Hardware Industry Co., Ltd., the rivet fixing mechanism is used to temporarily fix and position the rivet, and the pressure cylinder is used to drive the movement of the final shaft, so that the insertion nozzle can be Insert the rivet located in the rivet fixing mechanism into the product. Guangdong Yueluo Hardware Industry Co., Ltd. adopts mechanical drive and transmission, which has a high degree of automation and high work efficiency.
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 achieves the proposed object with a locking screw, which has the features of claim 5 . 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.
With the improvement of living standards, people's requirements for the comfort of sitting and bedding are gradually increasing. Independent pocket spring cushions have moderate hardness and are generally welcomed by people.
