Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (10), which can effectively prevent the problem of poor memory contact caused by the increase of the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixation, and can effectively control the deformation. effect.
The anti-theft screw of this structure has two disadvantages. One is that the polygonal block moves up and down in the polygonal hole, and the polygonal hole in the connecting piece and the polygonal hole on the threaded part have no limit structure. Because of the polygonal structure, the two If the polygonal holes of the parts cannot be aligned, dislocation occurs, and any edge may block the up and down movement of the polygonal block, which is very unsmooth during use. The second is that the shell of the lock cylinder and the hexagonal part are connected by pins, and the pins are exposed on the hexagonal parts, which are easily damaged and leave opportunities for theft; once the pin is pried off, the lock cylinder will be taken out, and the entire anti-theft screw will be lost. and the pin fixation is sometimes unstable, which is detrimental to theft.
The existing way to achieve radial locking of the shaft is generally to sleeve the positioning block on the shaft, and then use a cylindrical pin to pass through the positioning block to lock the shaft. The locking structure and method are as follows: A locking groove with an arc-shaped cross-section is set on the outer side of the shaft along the direction perpendicular to the axis of the shaft, an opening is set on the positioning block, and then a cylindrical pin is used to pass through the positioning block from the outside of the positioning block and screw the lock at one end of the cylindrical pin. When the lock nut is tightened, the opening on the positioning block will be deformed inwardly and locked on the shaft.
In order to achieve the above purpose, Yueluo provides the following technical solutions: threaded rivets include a nail rod, an expansion piece, and a nail sleeve, one end of the nail rod is provided with a mounting piece, and the side of the mounting piece away from the nail rod is movably installed with a mounting piece. There is a driving mechanism. The driving mechanism includes a mounting cylinder and a movable rod. A cross groove is formed at one end of the mounting piece close to the driving mechanism. The rod is movably installed on the inner side of the installation cylinder, and one end of the movable rod close to the cross groove is fixedly provided with a cross connecting piece that matches the cross groove, the cross connecting piece is matched with the cross groove, and the movable rod is far away from the cross groove. One end of the cross connecting piece is fixedly provided with a fixing piece, the fixing piece and the installation cylinder are screwed together by threads, the expansion piece is sleeved on the outer side of the nail rod, and the nail sleeve is movably installed on the nail rod away from the driving mechanism The outer side of one end of the nail rod is movably installed with a fixing mechanism.
Pins are frequently used parts in the machinery industry, especially in the mold manufacturing industry. With the development of the mold industry, the precision of mold manufacturing and assembly is getting higher and higher, and people are increasingly pursuing high-quality and close molds. Every detail on the mold is constantly improving, and the high-frequency use of the pins forces people to find a safer, simpler and more reliable way to disassemble and assemble.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: natural color pins, T-type pins, 8.8 grade bolts, metric hexagon head bolts, countersunk head cross hand screw bolts and other products, we can provide you with The right fastener solution for you.
