Service HotlineIn the repair process of the EDITION 700 gearbox, it is often necessary to replace the piston seal. When replacing the direct gear piston seal, the shaft spring retaining ring on it must be removed before the piston can be taken out for replacement. For the seal, since the piston return spring 3 presses the retaining ring 5 through the spring seat 4 (as shown in Figure 3), it cannot be taken out directly. It is necessary to press down the spring seat before taking out the retaining ring. Without special tools, it is not easy to remove the retaining ring. At present, it is a time-consuming, labor-intensive and unsafe job that requires multiple people to use a screwdriver and a prying board to forcefully squeeze and pry to remove the retaining ring.
In our life, there are many solid wood furniture. The parts of these furniture are positioned and connected by connecting parts such as screws or nails, so the surface of the furniture will leave marks of screws or nails, or even some cracks, so that the surface of the furniture will not be damaged. Flat, particularly unsightly.
Rivets are nail-shaped objects with a cap on one end: in riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are not restricted in form. Commonly used are R-type rivets, fan rivets, blind rivets, tree-shaped rivets Rivets, semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, hollow rivets, these usually use their own deformation to connect the riveted parts, generally less than 8 mm with cold rivets, larger than this size with Hot riveting, but there are exceptions. For example, the nameplate on some locks is riveted by the interference between the rivet and the lock body hole. The rivet pliers are used to cut rivets. The existing rivet pliers have a simple structure and cannot be riveted according to the The user needs to cut a certain length of rivets, and cutting the rivets is time-consuming and labor-intensive, and it is not convenient for people to use.
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.
In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical solutions: self-expanding semi-solid installation rivets, used for connecting and perforating two or more units of parts, including top core and rivet body, characterized in that : The top core lock slot opened on the concentric sheath along the longitudinal direction is snapped into and screwed and fixed in the concentric sheath, the top core extends downward into the top core rotary sleeve, the concentric sheath The sleeve is connected with the upper sealing sleeve of the lower body and is connected with the longitudinal axis, a hollow body is arranged below the rivet body, a joint is installed under the hollow body, and a supporting foot is connected to the joint, and the supporting foot and the turning The folding clips are staggered and distributed, the folding clips are concave-convex inclined surfaces, and the supporting feet are slidably connected with the folding clips.
