Heat resistance refers to both the oxidation resistance or gas medium corrosion resistance at high temperature, that is, thermal stability, and at the same time, it has sufficient strength at high temperature, that is, thermal strength. As the material requirements of products produced by customers are getting higher and higher, the requirements for screws used in product materials are also getting higher and higher. When product materials face harsh environments and special occasions, more and more high-quality mechanical properties of stainless steel screws are used. Therefore, stainless steel screws were selected. The requirements are getting higher and higher, and the material of stainless steel screws is getting higher and higher. Therefore, many ordinary stainless steel screws SUS201 are replaced by stainless steel SUS304 screws and stainless steel screws SUS316. Of course, if some requirements are not so high, general customers will choose stainless steel screws SUS201, which are relatively cheap in cost.
A nut is a commonly used fastener, usually combined with a screw to form a set of fastening devices. In order to effectively achieve a more effective tightening effect and prevent a single nut from loosening by itself, two nuts are used together in many places to further increase the tightening effect;
The above riveting requires special tools and equipment, which cannot be used in actual specific occasions. In the case of no electricity and no air, only manual tools can be used; and manual tools cannot be used for large types of rivets due to limited human strength. Moreover, after the rivet is disassembled, the rivet itself will be destroyed and cannot be reused.
At present, the washing machines used in the domestic market, especially the large-capacity washing machines, have high rotational inertia due to their large washing capacity. The wear between the input shaft and the clutch sleeve will cause the increase of the axial clearance. There will be strong shaking and loud noise, which will increase the wear and tear and affect the service life. In the prior art, the wave washer is used to prevent loosening and buffer shock, so that the gap between the input shaft and the clutch sleeve will not increase due to the wear of the two, which plays the role of automatic gap compensation, so as to ensure the clutch Smooth rotation, low noise and light wear ensure the reliable service life of the clutch.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a bayonet which is a T-shaped cylindrical pin with a misaligned through hole at the head, and a bayonet spring which is a ring-shaped spring steel wire whose ends are staggered. The retaining ring is clamped by the bayonet pin to fix the stop sleeve and the pin shaft together. A hydraulic excavator pin stopper with high disassembly and assembly efficiency and no need for a wrench. The technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is such that it includes a latch, a stop sleeve, a pin, a bayonet, and a circlip. The staggered end is clamped into the misaligned through hole of the plug, and screwed on the bottom of the stopper sleeve to fix the stopper sleeve and the pin shaft together. The latch is composed of a bayonet pin and a circlip, the circlip is screwed around the through hole of the bayonet pin to the root of the bayonet pin, and the stopper sleeve is tightly wrapped around the pin shaft, and the circlip is tightly against the bayonet pin. The head of the bayonet pin has two T-shaped cylindrical pins with staggered through holes, and the circlip is an annular spring steel wire whose ends are staggered. By adopting the pin shaft stopping method of the above technical scheme, it is extremely convenient and quick to disassemble and assemble the pin shaft. The bolt of Guangdong Yueluo Hardware Industry Co., Ltd. is only composed of a T-shaped cylindrical pin with two staggered through holes in the head and a ring-shaped spring steel wire with staggered ends. The structure is simple, convenient to manufacture, low cost and obvious. It is an excavator pin stop method with high disassembly and assembly efficiency, no need for a wrench and low manufacturing cost.
