Service HotlineThe slotted nut mainly refers to the hexagonal slotted nut, that is, the slot is machined above the hexagonal nut. It is used in conjunction with screw bolts with holes and cotter pins to prevent the relative rotation of the bolts and nuts, see GB6178 ~ 6181 and so on.
In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts.
Fasteners are a class of mechanical parts that are used for fastening connections and are widely used. It is used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic and other industries, in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments And supplies, etc., you can see all kinds of fasteners, which are widely used mechanical basic parts. In the fields of listed rails, construction machinery, etc., due to the harsh application environment, the requirements for fasteners are more stringent. If the fasteners are loosened, it may lead to serious consequences, resulting in a large amount of property damage, even serious life cost.
As we all know, when installing the outdoor unit of the air conditioner, most of the installers need to hang it on the outer wall. When tightening the machine foot screws, they all need to lean out of the window or climb out the whole person, and use a wrench to tighten it. . Therefore, it is difficult for the installer to operate, and it is easy to drop the installation materials such as screws and nuts, which is not only a waste of materials, but also easy to hurt personnel. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to solve the above problems, and provide a safe and labor-saving air conditioner outdoor unit machine foot screw installer that the installer does not have to lean out of the window or climb out of the room, and the installation materials are not easy to fall.
Usually, the car wheel is fixed on the axle sleeve with positioning pins and pins, and the tire hub and the sleeve are fastened on the axle with locking nuts, lock washers, and adjusting nuts. This structure can operate normally within a certain period of time when the vehicle speed is low and the vibration is small. However, when the car runs for a long time, especially when the road surface is uneven and the load changes sharply, the axle sleeve bears a great impact. Once the shear force generated is too large, the pin will break, and the nut will be loosened. Affected, the wheel and hub will be loose. If the maintenance is not timely, or the driver is inexperienced, the car will have an accident in which the tire falls off with the wheel hub. This is extremely dangerous. So people are looking for ways to prevent wheels and hubs from falling off
