Service HotlineWinnipeglead screw nut is provided with a through hole in the center for the screw rod to pass through, the surface of the through hole is provided with a screw thread engaged with the thread on the outer surface of the screw rod, and the surface of the through hole of the Winnipeglead screw nut is provided with a thread along the surface of the through hole. The oil storage groove in the axial direction, the depth of the oil storage groove is greater than the depth of the thread.
However, Yueluo still feels that there should be room for improvement for the screw improvement and screw that integrates stability, labor, fast and multi-function in the above two cases; for example, No. 556784 screw improvement Although the rod has the function of cutting and collecting chips, when the screw starts to screw into the object such as wood, it is hindered by the hardness of the object's tissue, so the staff still needs to exert considerable force, resulting in the lock. In the solid operation, there is still a lack of difficulty in screw-in operation; another example, new cases such as No. 289417 screw that integrates locking, stability, labor-saving, fast and multi-function, although the rod has the structural function of cutting and chip removal, it is The rod part is screwed into the middle section to the rear section of the object. Since the debris cannot be discharged, the rod part pushes the outer part of the object to the surrounding tissue of the object, so that the object expands outwards and even seriously damages the appearance of the object.
WinnipegCylindrical pins are generally used to connect, lock parts or for assembly positioning, and can also be used as parts of safety devices. The cylindrical pin is fixed in the pin hole by interference fit with the pin hole to fix parts, transmit power, or act as a positioning member. The prior art cylindrical pin press-fitting is shown in Figure 1. This kind of cylindrical pin prevents the cylindrical pin body from withdrawing through the locking force and axial friction force brought by the interference fit between the cylindrical pin body and the pin hole. However, the interference of the cylindrical pin body will gradually decrease during use, so that the firmness of the connection and the positioning accuracy will gradually decrease. Therefore, the cylindrical pin can be easily withdrawn during use, resulting in potential safety hazards.
WinnipegGaskets are mechanical components used for cooperation between two objects, which play a role in preventing pressure, corrosion and leakage of pipes from natural thermal expansion and contraction between two objects. By using the gasket in conjunction with the bolt and nut, the gasket can increase the contact area between the bolt and nut and the metal parts, and play the role of buffering and shock absorption to prevent the thread from loosening.
door cover structure with hidden screws includes a glass panel, an inner door cover, a computer board and a sealing strip, an adhesive bracket is adhered to the back of the glass panel, the inner door cover is fixedly connected with the adhesive bracket through screws, and the computer board is arranged on the glass panel. In the cavity formed by the panel and the inner door cover, the inner door cover is provided with a sealing slot, the sealing strip is embedded in the sealing slot, and the bottom of the sealing slot is provided with a mounting hole for the screw to pass through, and the glue The bracket is provided with a fixing hole matched with a screw thread, and the screw passes through the installation hole of the inner door cover and is threadedly connected with the fixing hole of the adhesive bracket, so as to fixedly connect the inner door cover and the glass panel. The screw is hidden in the sealing groove of the door cover, and is sealed with water through the sealing strip. The appearance is beautiful, easy to disassemble and assemble, and it can effectively protect the screw from rust.
