Service HotlineThe technical solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is: a waterproof rivet, including an integrally formed waterproof cap and a rivet rod for waterproofing, and the waterproof cap includes a lower part that is fixedly connected with the rivet rod. An end face, the lower end face includes a fixing portion arranged in order from the center position of the lower end face to the outside, a buffer portion arranged circumferentially with the fixing portion as the center, and a waterproof portion arranged circumferentially with the fixing portion as the center, the fixing portion and the rivet The rods are fixedly connected, and the section of the waterproof part is a figure-eight shape.
rivet is a nail-shaped object used to join two parts or components with a through hole and 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 informal. Commonly used are R-type rivets, fan rivets, blind rivets, blind rivets, tree rivets, semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, hollow rivets, these usually use their own deformation Connect the riveted parts. Generally less than 8 mm with cold riveting, 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.
At present, the screws used by people are not provided with a device that does not loosen, especially in some key parts, if the screws are loosened, it will cause heavy losses. In order to overcome the current situation, there is no device on the screw to prevent the screw from loosening, which may cause heavy losses. Guangdong Yueluo Hardware Industry Co., Ltd. The inner part will not be loose, and it will save people the trouble of maintenance and reduce the hidden danger of accidents. The solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is to make a special screw and nut, set a stop groove on the screw, and then set a stop rod on the nut. After the screw is tightened , let the backstop rod be stuck in the backstop groove to prevent the screw from loosening. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is to ensure that the screws will not loosen during the service period, reducing the hidden danger of accidents and reducing the maintenance rate. Guangdong Yueluo Hardware Industry Co., Ltd. is further described below in conjunction with the accompanying drawings and embodiments
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.
At present, the commonly used fastener loosening prevention methods generally include non-removable anti-loosening solutions and friction-increasing anti-loosening solutions. The non-removable anti-loosening scheme uses welding, bonding or punch point riveting to change the detachable threaded connection into a non-detachable threaded connection. In the non-removable anti-loosening scheme, the threaded fasteners cannot be reused and the operation is troublesome. It is often used in some important occasions that require high anti-loosening performance without disassembly. The anti-loosening scheme that increases the frictional force uses the method of increasing the frictional force of the bolt (screw) head and the end face of the nut to achieve the purpose of anti-loosening. The anti-loosening solution that increases friction is not limited by space and can be disassembled repeatedly, but the reliability is poor. After a certain period of work, the anti-loosening effect will be reduced due to vibration and other reasons.
