Supply of Grade 12.9 British American hexagonal socket plug without gasket, plug, oil plug, and plug

The existing open-end blind rivets are widely used, usually consisting of iron riveting shells and iron or stainless steel rivet cores. During the riveting process, these open-end rivets often have unstable and high pulling force of the rivet core, which leads to the rivet head directly pulling into the foam layer and damaging the product structure during riveting. And there may be safety hazards such as scratching operators during installation due to the exposed nail core. At the same time, due to the expansion of the rivet shell hole, the nail head may become loose inside.

Guangdong Yueluo Hardware Industry Co., Ltd. provides screw and nut disassembly tools with a simple structure that can simultaneously disassemble screws and nuts in a narrow space to overcome the current technical problem of not being able to disassemble screws and nuts at the same time.

As a commonly used data communication device, connectors are widely used in computers and televisions. As common connectors such as D-SUB and DVI are composed of a male and a female seat, holes are set in the corresponding positions of the iron shells of the male and female seats. The male seat holes are connected with rivets, and the female seat holes are corresponding with fixing screws. After the connection between the male and female seats is completed, tighten the screws to tightly connect the male and female seats. When assembling on devices such as computers or televisions, rivets have a fixed assembly direction, and the fixation of the rivet direction is crucial for assembly. However, the existing connectors do not have anti rotation devices for the iron shell holes connected to the rivets, making the rivets unable to be positioned during the assembly process and prone to rotation misalignment. As shown in Figure 4, it is necessary to adjust the direction, which causes great difficulties for assembly and reduces production efficiency.

Developing a structure with simple production, reasonable structure, and stable feeding is of great significance for the field of riveting automation. Technical realization elements: the purpose of the utility model is to overcome the shortcomings of the existing technology and provide an automatic feeding device for press rivet nuts. The device is compact in structure and reasonable in design, which can realize the automatic transmission of press rivet nuts on the press rivet mold, reduce the use of space, improve work efficiency and save Labor burden. According to the technical solution provided by the present utility model, a riveting nut automatic feeding device is characterized in that it includes a mounting bracket, a connecting bracket, a flipping plate bracket, a pushing cylinder, a pushing block, and a flipping plate; The flip board bracket is arranged below the installation bracket and connected to the installation bracket through a connecting frame.

The commonly used methods for preventing loosening of fasteners currently include non detachable locking schemes and locking schemes that increase friction. The non detachable anti loosening scheme uses methods such as welding, bonding, or spot riveting to change the detachable threaded connection into a non detachable threaded connection. In the non detachable locking scheme, Threaded fastener can not be reused, and the operation is troublesome. They are often used in some important occasions that require high locking performance without disassembly. The anti loosening plan of increasing friction force uses the method of increasing the friction force between the bolt (screw) head and the nut end face to achieve the purpose of anti loosening. The anti loosening scheme for increasing friction is not limited by space and can be disassembled repeatedly, but its reliability is poor. After working for a certain period of time, the anti loosening effect will be reduced due to vibration and other reasons.
