Service HotlineHowever, due to a radial external tension, the external tension is caused by the tightening axial force generated by the tightening torque, and the phenomenon of open ring expansion occurs, and the spring washer often breaks due to hydrogen embrittlement. The nut exerts uneven pressure on the flat washer through the spring washer. And the friction coefficient between the spring washer and the nut and the flat washer is very small, and the phenomenon of vibration, rotation and relaxation occurs.
screw is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. When using screws to fasten objects and parts, it is often necessary to use screws with spring washers and flat washers to lock and fix the relative position, so as to improve the stability of the fastening connection and make the screws less prone to loosening. However, in the prior art, the method of manually inserting the spring washer and the flat washer in sequence is generally used, which not only increases the workload of the staff, but also makes the installation efficiency relatively low. On the other hand, the traditional screw with a gasket only has the function of fixing, Without the function of sealing, it cannot be applied to special equipment such as oil tanks and airtight cabins. Therefore, it is necessary to design a screw that can reduce the workload and have its own sealing structure.
The one-way nut provided by Guangdong Yueluo Hardware Industry Co., Ltd. has the following characteristics: a. It is composed of a screw sleeve 1, a threaded core 2, a cover 3, a spring 4 and a bead 5; b. There is a stop 7 on the outer edge of the core 2 and a ring of grooves 8; c. The screw sleeve 1 is sleeved on the screw core 2; d. 4 is enclosed in hole 6.
An anti-loosening nut structure includes a flat nut and an oblique nut. One end surface of the oblique nut is an oblique surface, and an angle is formed between the oblique surface and the vertical line of the screw hole axis of the oblique nut. Nuts are installed on the bolts one after another, and the mating contact surfaces of the two nuts include the inclined surface, which are tightened in sequence.
Gaskets are widely used in the machinery industry. According to the different needs of machinery and equipment in different industries, the structural forms of the sealing points are also different. Plum washer is one of the commonly used seals. It is commonly used between the pump and the motor coupling. In the actual production process of the enterprise, it is found that due to the influence of the material and structure, this type of gasket in common use can withstand impact force. Small, the septum is easily damaged. Because the current plum washers are all one-piece structures, even if one or several of the partitions are damaged, they need to be replaced as a whole. Although the value of a single plum washer is low, it needs to be shut down for maintenance and replacement almost every week. It also seriously affects the normal production of the enterprise, and the one-piece plum blossom gasket is also difficult to repair, adding unnecessary use costs to the enterprise. For this reason, the plum blossom gasket needs to be improved to strengthen the impact resistance of the gasket, and can be repeated Maintenance and use, prolong the maintenance cycle of the equipment, and ensure the normal production of the enterprise. The purpose of the utility model Yueluo is to solve the above-mentioned deficiencies in the existing technology, improve the existing technology, and provide a simple structure, which strengthens the impact resistance of the gasket, and can be repeatedly maintained and used to prolong the maintenance of the equipment. The cycle guarantees the plum blossom elastic washer normally produced by the enterprise. In order to achieve the above purpose, Yueluo is achieved through the following technical solutions-namely a plum blossom elastic washer, including an elastic washer body with a partition, the technical point is that the washer body is composed of a washer base and a partition that is independent of each other. , the septum and the gasket base are fixedly connected into one through the fixing piece. In order to further strengthen the impact resistance of Yueluo, the contact parts of the spacer and the washer base are respectively processed with a limited clamping table and a matching groove, so that the spacer and the washer base can be better integrated into one. According to the different specifications of the torx washer, the spacer and the washer can be fixed as a whole by rivets; or by screws. In addition, a semi-rigid tightening ring with grooves is embedded inside the washer base, and the width of the tightening ring is smaller than the width of the washer base; the ends of the rivets or screws are located in the grooves of the tightening ring, so as not to affect the performance of the torx washer JH is often installed. After the above improvement, Yueluo has improved the one-piece structure of the plum-blossom washer into a split structure and adopted a variety of fixed structure forms, so it has a simple structure, strengthens the impact resistance of the gasket, and can be repeatedly maintained and used. , Extend the maintenance cycle of the equipment and ensure the advantages of the normal production of the enterprise.
