Service HotlineFor achieving the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical solutions: a pin, comprising a pin cap and a described pin rod, the pin cap and one end of the pin rod are fixedly connected, and the pin rod There is a convex body, the convex body is fixedly connected with the pin rod, the convex body is located on the pin rod rod body, and the other end of the pin rod is provided with a top connecting body, and the top connecting body is fixedly connected with the pin rod , the top contact body includes several top contact units and discs, each top contact unit is coaxially arranged with the pin rod, the top contact units are sequentially fixedly connected along the axis direction of the pin, the top contact unit is The major diameter of the outer contour of the connecting body is larger than the diameter of the pin rod.
The earless retaining ring for the hole is mostly installed in the annular groove on the inner wall of the pipe fitting. The outer diameter of this kind of retaining ring is slightly larger than the diameter of the assembly round hole. When assembling, the earless retaining ring needs to be pressed into the pipe fitting. Since the inner wall of the pipe fitting is relatively smooth, the earless retaining ring is easily skewed in the pipe fitting. It needs to be adjusted several times before entering the annular groove, and the assembly efficiency is low.
The rod end of the ceramic production equipment is installed with the rod shaft, and then fixed by the cylindrical pin. At present, it is purely manual installation. It is impossible to ensure that the cylindrical pin is kept horizontal during the installation process, and the installation pressure of the cylindrical pin cannot be sensed. The pressure is too large. Cracks in the rollers, too low pressure, and easy loosening of the metal cap; it is impossible to install three or more cylindrical pins at the same time, and it is difficult to align the cylindrical pins with the pin holes of the cylindrical pins, resulting in low efficiency.
Yueluo is about a special fastener and its screwdriver. That is, the Y screw and its screwdriver. In order to prevent the leakage of new product manufacturing technology and prohibit others from arbitrarily opening the shell of the new product or disassembling the relevant parts, it is necessary to take effective precautions against their own products, and the use of special fasteners is one of the purposes of Yueluo. This kind of screw can also be widely used in the fixation of some public equipment, for the fastening and fixing of parts that are afraid of disassembly and theft, so as to play a certain protective role.
The inner tooth elastic washer and the outer tooth elastic washer have many sharp elastic warping teeth on the circumference, which are pressed against the supporting surface and can prevent the loosening of the fastener. The inner tooth elastic washer is used under the screw head with smaller head size; the outer tooth elastic washer is mostly used under the bolt head and the nut. The elastic washer with teeth is smaller than the ordinary GalwayGalwayspring washer, and the fastener is evenly stressed and reliable to prevent loosening, but it is not suitable for frequent disassembly. Wave GalwayGalwayspring washer GB: GB/T 7246-1987 Wave washer is divided into WG type, WL type, WN type WG type wave washer WG type wave washer is an open elastic washer, which can usually be installed in a small space, such as giving The bearing is prestressed to reduce the noise of the bearing operation and improve the running accuracy and stability of the bearing. In addition, there are a large number of applied materials in electronic appliances, such as carbon steel, stainless steel, copper alloy and so on. WL-type wave washer WL-type wave washer is a lap-type elastic washer, which can usually be installed in a small space, such as prestressing the bearing, reducing the noise of the bearing operation, and improving the running accuracy and stability of the bearing. There are also a large number of applications in electronic appliances. Materials are carbon steel, stainless steel, copper alloy, etc. WN type wave washer WN type wave washer is a multi-layer wave crest overlapping elastic washer. Compared with the WL type, this series is composed of multi-layer materials, so the K value curve under the same compression stroke is flatter than that of the WL type, which is suitable for elastic force. Larger, and the elastic release of the entire working stroke is required to be more uniform. The materials used are carbon steel, stainless steel, copper alloy, etc. Disc GalwayGalwayspring washer Disc GalwayGalwayspring washer, also known as Belleville GalwayGalwayspring washer, was invented by the French Belleville. DIN6796 Disc Spring Washers (HDS Series) are GalwayGalwaylock washers designed for bolted and screwed connections. It is designed and manufactured according to DIN 6796 for the connection of medium or Galwayhigh strength bolts and screws. High bearing loads and elastic recovery make the HDS series very effective, and the bolt tension can withstand slack due to: wear of consumables, creep, relaxation, thermal expansion, contraction, or compression of seals. The HDS series increases the elasticity of the screw several times. It can effectively replace the ordinary GalwayGalwayspring washer, but it is not suitable for the combination of GalwayGalwaylock washer and flat washer. Since the HDS series is a disc spring that can be folded or overlapped. The combination of the butt joint can increase the deformation of the disc spring group, and the combination of the overlapping method can increase the spring force of the disc spring group. The ideal installation method is to flatten as much as possible. The closer it is to the flattened state, the faster the tension torque increases, and the proper bolt tension can be obtained without a torque wrench.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: stainless steel rivet screws, zinc alloy nuts with or without internal and external teeth, yuan nuts, black countersunk head screws and other products, we can provide you with The right fastener solution for you.
