Pins are widely used. In the connection of the rotating mechanism of two moving components, such as the crank mechanism, the turning mechanism, the connection between the hydraulic cylinder and the moving parts, the pins are used. kind. In order to ensure the normal use of the running equipment and prevent the cylindrical pin from slipping out and falling off during use, some anti-falling methods are usually used at the head of the pin, such as 1. Drill holes and insert cotter pins to prevent the pins from slipping out; 2. The external thread is tightened with a nut to prevent the pin from slipping out; 3. The slot is clamped with a circlip to prevent it from slipping out, etc. These measures make the cylindrical pin very practical in the case of infrequent disassembly and assembly, but in the actual use of the field, in order to prevent the collision of some equipment during each troubleshooting or maintenance, the pin needs to be pulled out and turned up, etc. After the failure or maintenance is completed, put down and then insert the pin to restore, this process will bring trouble to the actual operator. For example, special tools must be brought with you every time you disassemble and assemble the pin, and the split pin or the circlip is easily damaged after repeated disassembly and assembly. , In order to save trouble, the operator sometimes uses iron wire to thread or fasten it instead, and even does not remove the pin for the sake of speed and convenience, which is easy to cause damage to the equipment when dealing with faults.

The middle pins on upright and horizontal pianos are also called balance pins. The middle pins are installed on the middle sleepers of the keyboard frame and play the role of fixing the keys. Generally, there are 88 keys in the piano. The pins are matched with the pin holes, and the keys are installed on each middle pin one by one through the pin holes. Due to the large number of middle pins and keys, in the production and installation process, in order to ensure the flatness of the 88 keys after installation, it is necessary to debug the middle pins and keys one by one, or add paper circles to the middle fixed part on the middle pins. The flatness of the 88 keys is kept the same. This debugging method is extremely cumbersome and increases the workload of debugging. Moreover, when adding paper circles, the keys need to be disassembled frequently. Due to the limitation of the installation space of the keys, it is troublesome to disassemble the keys, and it is easy to install and disassemble the keys many times. Damage to the pin holes on the keys, degrading the quality of the piano.

Hexagon socket head cap screws are indispensable industrial necessities in daily life and have important tasks in industry. But ordinary hexagon socket head cap screws must be installed and disassembled with special tools. For ordinary users, some simple disassembly and maintenance work are often unable to be handled due to lack of tools.

Fan rivets are specially designed for manual installation. They can be pulled in through the holes of the panel or the bottom frame. They are made of elastomer material with good toughness and can be installed quickly even in interference assembly. The design is clever and has elastic function. It is not easy to slide out after being pulled in with the corresponding aperture. The fan rivets are mainly used in the fixing of electronic computer case fans, heat sinks and chips, with anti-vibration and noise reduction.

In some embodiments, the rivet fixing mechanism includes a left moving block, a right moving block, a return spring and a bracket, wherein both the left moving block and the right moving block are movably mounted on the bracket, and the left moving block and the right moving block are connected by a return spring, The insertion mouth can extend between the left moving block and the right moving block, and withstand the left moving block and the right moving block. The left moving block is provided with a left half hole, and the right moving block is provided with a right half hole matching the left half hole. hole. Therefore, when the insertion nozzle is not inserted, the left moving block and the right moving block can be combined together by the return spring, so that the left half hole and the right half hole are combined into one hole to fix and position the rivet, and when the insertion nozzle is inserted When , the left moving block and the right moving block will be pushed up by the insertion mouth to separate the left half hole and the right half hole, so that the rivet is no longer fixed and can be inserted with the movement of the insertion mouth.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: round head hexagon socket head three combination screws, black bucket bolts, 316 nuts, 20 type 30 type 40 and other products, we can provide you with The right fastener solution for you.
