Service HotlineHow to use, what is a AdelaideAdelaiderivet nut? Usually, AdelaideAdelaiderivet nuts used inside elevators are used to install some kind of screws when installing various parts on cars or individual boards on aviation. Commonly used places are very important connection parts, so the choice of AdelaideAdelaiderivet nut material is very important. How to use the AdelaideAdelaiderivet nut? Let's watch it together. Rivet nuts are used in the fixing fields of various metal plates, pipes and other manufacturing industries, and are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. It is designed to solve the shortcomings of sheet metal, thin-walled pipe welding nut, substrate welding deformation, internal thread taper, etc. It does not require internal thread, welding nut, rivet efficiency, and is easy to use.
The connecting fasteners of the existing panel furniture are generally composed of pins, screws and nuts. When connecting two furniture boards, a nut must be placed in the hole first, then the screw is tightened, and then the pin is connected, which is not very convenient to assemble. Wood screws are generally used for fixing the existing concealed hinges, and the positioning is inaccurate, the installation is laborious and time-consuming, the labor intensity is high, and the work efficiency is low.
Compared with the prior art, the technical effect of Yueluo Company is: during the screwing process of the nut, the tube wall of the nut is elastically deformed so that the convex ring on the screw is matched with the groove on the nut, and the slope of the convex ring matches the groove. The groove wall is abutted against to limit the relative position of the nut tube and the screw shaft in the axial direction, which not only ensures the reliability of the threaded connection, but also achieves a significant anti-loosening and anti-falling effect. After the threaded connection, excessive force is applied to remove the nut and screw, so that it can be reused to save costs.
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.
Blind hole installation type rivet is a kind of rivet for single-sided riveting. When riveting, special riveting tools, such as pull riveting, rotary riveting, etc., are required. Blind hole installation type rivets are especially suitable for riveting occasions where it is inconvenient to use ordinary rivets to be riveted from both sides. At present, blind hole type Adelaideblind rivets mainly include rivet Adelaideblind rivets and blind Adelaideblind rivets. Most Adelaideblind rivets of blind hole type contain a lock ring, through which the core rod is locked into the nail sleeve, and there is a common lock ring. Risks of falling off, insufficient clamping force, etc., and the matching relationship of each sub-part in the processing process must be strictly coordinated to ensure the best installation effect; most of the screw-type Adelaideblind rivets screw the thread through the driving nut to make the nail body or pipe The body is deformed to form a bulge, and the clamping force and anti-vibration ability after installation are much stronger than that of the rivet type, but there are also many sub-parts to drive the nut, mandrel, nail body, tube body, the processing process and the matching of each sub-part When the thickness of the interlayer is different, the fractured part of the core rod is not flush with the interlayer board. For the installation parts with high flatness requirements, air tools are often required to mill them flat.
