T-bolt with a spring, used for undercutting the opening of the outer closed cavity, including a head and a rod part connected in one piece, and also including a strip spacer, a spring and a pull rod, and the length of the strip spacer is greater than The opening, the connecting part of the head and the rod part are set as polygonal anti-rotation blocks, and the strip-shaped spacer is provided with anti-rotation holes for inserting the anti-rotation blocks, and the shape and size of the anti-rotation holes are the same as The size of the anti-rotation hole is smaller than that of the head; the spring is threadedly matched with the rod part, and is fixedly connected with the pull rod, and the pull rod moves away from the rod part along the axial direction of the rod part One side of the head extends. The utility model can be easily and reliably buckled in the opening of the airtight cavity, thereby facilitating the installation and connection of external parts.
From the perspective of use: The bolted connection of the main components of the building structure is generally connected by high-strength bolts. Ordinary bolts can be reused, but high-strength bolts cannot be reused. High-strength bolts are generally used for permanent connections. The high-strength bolts are prestressed bolts. The friction type uses a torque wrench to apply the specified prestress, and the pressure type screw off the torx head. Ordinary bolts have poor shear performance and can be used in secondary structural parts. Ordinary bolts just need to be tightened. Ordinary bolts are generally 4.4, 4.8, 5.6 and 8.8. High-strength bolts are generally 8.8 and 10.9, of which 10.9 is mostly. Level 8.8 is the same level as 8.8S. The mechanical properties and calculation methods of ordinary bolts and high-strength bolts are different. The stress of high-strength bolts is firstly by applying a pre-tension force P inside, and then generating frictional resistance on the contact surface between the connected parts to bear the external load, while ordinary bolts directly bear the external load.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a flat gasket that improves the lubrication performance of the contact surface and reduces the friction of the contact surface. Yueluo is implemented through the following technical solutions: a flat gasket with straight upper and lower end faces, characterized in that: the upper and lower end faces are dotted with pits, the pits are spherical pits, and the pit diameter is 2-3mm , the pit depth is between 0.5-lmm. The bottoms of some of the pits are provided with through holes penetrating the upper and lower end faces, and the diameter of the through holes is not greater than 0.5mm. The flat gaskets provided by Yueluo have pits with reasonable design parameters on the upper and lower end faces of the flat gaskets. The pits can store oil, so the lubrication of the contact surfaces of the gaskets can be well improved. It can effectively reduce the friction of the contact surface of the gasket and reduce the failure rate; in addition, the design of the through hole enables a smooth oil passage between the upper and lower end faces of the gasket, ensuring that the upper and lower end faces can be well lubricated.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of anti-loosening cylindrical pin with grooves specially designed for the multi-link transmission paint mixing mixer, which is specially designed for the problems existing in the above-mentioned prior art. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to realize through the following technical solutions: a kind of anti-loose cylindrical pin with groove, wherein: a plurality of axial V-shaped grooves are provided on the cylindrical pin, and the V-shaped groove Arrange evenly on cylindrical pins. There are three to four axial V-shaped grooves on the cylindrical pin. When Guangdong Yueluo Hardware Industry Co., Ltd. is in use, the cylindrical pin with V-shaped groove is installed in the vertical shaft, and cooperates with the U-shaped groove on the connecting rod to transmit torque. The cylindrical pin of the V-groove structure is an interference fit with the mounting hole of the vertical shaft. The biggest feature of Guangdong Yueluo Hardware Industry Co., Ltd. compared with the existing technology is that the cylindrical pin is used as a vertical shaft to connect with the connecting rod for torque transmission, which gives full play to the impact resistance and fatigue resistance of the cylindrical pin. The cylindrical pin has an interference fit with the pin hole, and each edge of the V-groove structure distributed on the cylindrical pin body will penetrate into the inner wall of the pin hole to prevent loosening.
