The front wall sound insulation pad is used to absorb the heat and noise transmitted by the firewall, and also plays the role of heat insulation and vibration isolation, ensuring a relatively quiet and comfortable environment in the car and improving ride comfort. As shown in FIGS. 1 and 2 , the front wall sound insulation and heat insulation pad 101 is generally fixed to the vehicle body by means of screw buckles 102 . The screws 100 are clamped by the clamping feet 103 in the screw The limiting rib 104 clamps the screw 100. After the screw 100 is clamped into the screw buckle 102, the tail end of the screw 100 is exposed, which is easy to scratch the operator when assembling other components, and the exposed screw 100 is easy to cause corrosion, thereby affecting the connection strength of the screw 100, and also The service life of the screw 107 is reduced.

Before the special vehicle is refitted, the chassis and the car frame should be reinforced again, and the fastened part of the rivets should be disassembled before the car frame is reinforced.

Guangdong Yueluo Hardware Industry Co., Ltd. discloses a countersunk head rivet. The countersunk head rivet includes a nail body and a mandrel. The nail body is tubular, and one end is provided with a nail cap. The mandrel passes through the nail body from the cap end and forms a diameter. For the nail head larger than the internal diameter of the nail, the nail cap is close to the end of the nail head to form a countersunk head. When the countersunk head rivet is in use, the nail body forms a countersunk head structure to the riveted metal piece under the extrusion of the nail head, so that the two riveted metal pieces are firmly riveted without the nail body protruding from the metal piece.

captive 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.

Screws are a kind of fasteners commonly used in machinery, but most of the screws commonly used in the market are standard parts. The screws themselves are ordinary and have no function of preventing loosening and protecting the matrix. Therefore, in order to prevent the screws from loosening during use , Usually it is necessary to configure additional elastic washers, flat washers, etc. that are suitable for screws, and these elastic washers and flat washers are mostly metal products. During use, it is easy to wear with the body base and damage the protection of the sheet metal base. After long-term use, metal washers are easy to rust, which affects the tightening effect and appearance of screws. In addition, the use of metal washers not only increases the weight and cost, but also the assembly process is complicated and cumbersome, and the anti-loosening and anti-wear effects are not ideal. .
