As the most common hardware, screws and nuts are widely used in construction and machinery fields. However, existing screws and nuts are easily corroded to varying degrees in the natural environment, especially the threads on screws and nuts are corroded After that, the whole screw and nut are useless, and people have to discard them, which will inevitably lead to a lot of waste of resources.
As we all know, whether it is the necessities in people's life or the equipment in industrial production, there will be a structure of screws and screw holes on it. This kind of structure that can simply fix some components together has been widely used in various fields. For the installation and removal of screws, people invented manual screwdrivers, and then to electric screwdrivers and so on. For manual screwdrivers, the operator needs to manually install or remove the screws. When encountering small screws, it can still handle it. When encountering large screws, due to people's limited strength, they may not install the screws in place, so it was invented. Electric screw. When installing the screw, which is widely used in the market, the operator needs to hold the screw handle, fix the screw on the screw port, and then align the screw with the corresponding screw hole for screwing. The disadvantage of this kind of screw is that it is heavy in quality and laborious to operate, and secondly, the operator will be injured due to operating errors, and the consequences are extremely serious. In view of this deficiency, people fix the screws on a work frame, so that before installing the screws, the operator only needs to adjust the screws to the designated position, and then the screws can be installed, which is convenient and simple. However, there are still potential safety hazards. In the process of adjusting the screw, it is still possible that the power of the screw may be turned on by mistake due to operating errors, resulting in injury to the operator. In view of the above-mentioned defects, it is necessary to invent a screw installation method with an anti-missing function.
The quick-install and quick-release nut uses the threaded block to move radially and axially along the inclined surface at the same time to achieve the cohesion and separation of the threaded block. However, the nut has a complex structure and is difficult to manufacture, and the internal and external threads may not be properly locked during use. Occurs, bearing capacity and reliability are poor.
Slotted round nut, side hole round nut, end face hole round nut, small round nut round nut, ring nut, wing nut copper nut, inlaid copper nut, knurled copper nut, embedded copper nut, injection copper Nuts and other alloys zinc-copper alloy nuts and other anti-loosening principles Edit the locking nut The locking nut DIC-LOCK locking nut is composed of two parts, each part has a staggered cam, due to the internal wedge design, the slope angle is greater than the bolt's The angle of the nut, the combination is tightly integrated into a whole. When vibration occurs, the raised parts of the DIC-LOCK locknut stagger with each other to generate lifting tension, thereby achieving the anti-loosening effect.
The paint mixing mixer used for color matching in the auto repair industry uses a multi-link connection transmission as the main driving force. The transmission of torque has higher quality requirements for the impact resistance and fatigue resistance of the cotter pin. During the use of the cotter pin, it was found that the cracking phenomenon occurred due to insufficient strength, resulting in the machine not running. In the existing multi-link transmission mode of the paint mixing mixer, the connecting rod drives more than 10 paint pots in each layer of the frame to stir, and the bottom connecting rod is also responsible for the transmission of the torque of the upper connecting rod, which leads to the connection between the connecting rod and the connecting rod. The pins connected by the rods must have strong impact resistance and fatigue resistance, and must have a certain anti-loosening function.
