Service Hotlinecaptive screw is a commonly used pressure riveting part. Usually the captive screws are directly riveted on the motherboard, so as to play the role of fixing the components, and there is a high requirement for the distance between the opening holes on the component. Once the distance between the through holes on the component and the If the distances between the riveting holes on the motherboard do not match, the components cannot be riveted on the motherboard, which will result in defective or scrapped products, thereby increasing production costs and reducing production efficiency.
In chemical production equipment, the cylinder body and the head cover need to be connected and sealed. The traditional sealing structure is to connect the two with a screw, add a non-metallic gasket in the middle and fix it with a nut. However, such a sealing structure only controls the tightening torque, and has the technical defect that the sealing ring will be twisted or even broken during repeated loading and unloading of the cylinder head cover, resulting in poor sealing performance.
Spring mattresses and spring seat cushions are modern and commonly used furniture products with better performance, and their cushion cores are composed of springs. It makes full use of the advantages of good spring elasticity, good support, strong air permeability and durability. The traditional spring pad is a spring with a thicker wire diameter, which is connected and fixed by steel wires, and has high hardness. Most of the elders of the older generation often use linked spring beds, but if they sleep in a fixed position for a long time or are accustomed to sitting on the side and corners of the bed, or flip the mattress irregularly, it is easy to cause depression and elastic fatigue.
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.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35 , and the screws enter the screw accommodating hole 43 from the discharge port through the guide rail 6 . The slotting is carried out, which improves the efficiency and saves the labor cost.
