Service HotlineAt present, in the riveting of automobile and motor car parts, especially the parts that have vibration and need to move frequently, such as automobile steering gear, ordinary rivets and double-drum rivets are mostly used for riveting. Due to the limitations of the structure of these two products After riveting, the product has the defect of insufficient strength and easy to loosen and fall off, and it cannot be disassembled and can only be used once, thus affecting the quality and performance of the riveted product.
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.
The traditional dismantling of automobile girder rivets is mostly carried out manually, which has many defects such as long disassembly time, low disassembly efficiency, labor-intensive, time-consuming, labor-intensive, low operation safety, difficult protection, and easy injury.
When fixing the centrifugal fan, since the gaskets, washers and nuts are separate parts, many parts are used in the whole process, and it is easy to miss the installation of parts; The volume of the parts is relatively small, and it is not easy to remove them when they are transferred into the air conditioner through the gap of the centrifugal fan blades, resulting in foreign bodies in the machine.
Existing bolt and nut connections usually use threads for connection, and this connection method has two main drawbacks. First, tools are required to be used to lock it during installation, and it takes a long time to complete, which is time-consuming and labor-intensive; Second, the installed bolts and nuts are prone to loosening after a period of time, resulting in loosening and shaking between the connecting parts. Therefore, there is a need for a bolt and nut fastener that is easy to install and can effectively prevent the loose fit of the bolt and nut, so as to solve the problems existing in the prior art.
