Service HotlineAt present, the main four kinds of anti-shedding nuts are still prone to falling off. Friction and anti-shedding are in the case of shock, vibration and variable load. At the beginning, the nut will decrease in preload due to relaxation. As the number of vibrations increases, the loss of preload will increase. The force increases slowly, eventually causing the nut to loosen and the threaded connection to fail. The mechanical nut is prevented from falling off by adding a stopper, which makes it inconvenient to disassemble. The riveting and punching prevention is to prevent the separation by welding, bonding, etc. This method can only be disassembled by destroying the bolt pair.
T-slot convenient bolt that can be used for the middle port of the T-slot and directly realizes the assembly and tightening of the bolt and the nut. Technical Background At present, the bolts for T-slots are assembled from two side ports of the T-slots. When the length of the T-slot is long, it is time-consuming and laborious to install from the side port to the center port at the designated position. In addition, the two side ports of the T-slot are often blocked by other components, and the bolts for the T-slot cannot be installed or removed without disassembling other components. The utility model makes some improvements to the prior art. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a T-slot convenient bolt with simple structure and convenient mounting and dismounting for the current situation that the existing T-slot bolts are inconvenient to install and disassemble.
At present, the connecting shafts of commonly used food processing knives on the market generally use square bayonet, which is not easy to install parts, and it is time-consuming and laborious when replacing parts; Increased processing costs. There is also a link structure with a circular bayonet on the market, but it is easy to loosen and not firm after the entire food processor is used for a period of time, which affects the use of the machine. Therefore, a connection structure that is easy to operate and simple to process is urgently needed.
concealed screw fastener includes a washer, a screw and a shield, one end of the screw is provided with an end cap, the screw penetrates the washer and the end cap is supported on the washer, and the shield covers the end of the screw The cap is peripheral and connected to the gasket. When in use, firstly pass the screw through the washer and then drive it into the screw hole of the connected piece, and then cover the shield on the outer circumference of the end cap of the screw and connect it with the washer.
Such flat gaskets typically include passage openings for fluids through which fluid can flow from one side of the flat gasket to the other side of the flat gasket. In addition, functional elements may be inserted into such passage openings, eg valve elements blocking passage in one direction, or orifice elements defining passage in one or both directions.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: round head anti-theft bolts, black nylon screws, hexagon single-head, half-tooth external hexagon screws and other products, we can provide you with suitable fastening for you piece solution.
