Service HotlineHowever, 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 screwing in operation; another example, new cases such as No. 289408 screw that integrates locking, stability, labor, 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.
The nuts in the prior art are easy to fall off during work, especially in harsh environments or environments with large vibrations. Sometimes it is necessary to add parts such as gaskets to prevent them from falling off, but they are still easy to fall off and cause harm.
screw assembly includes a screw body, a spring and a mounting plate, the screw body includes a nut and a screw, the top of the screw is provided with a polygonal notch, the screw is composed of upper and lower parts, and the diameter of the upper part of the screw is larger than that of the lower part of the screw A slot is arranged at the lower end of the upper part of the screw rod; a slot corresponding to the spring is arranged on the mounting plate, and an extension slot is arranged in the slot, and the extension slot is L-shaped; an extension body is arranged at one end of the spring , the extension body corresponds to the extension slot; the spring is installed between the nut and the mounting plate, and the spring extension body is installed in the slot extension slot. Guangdong Yueluo Hardware Industry Co., Ltd. has the following advantages: it can prevent the spring from rotating with the rotation of the screw, the structure is simple, and the use is convenient.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35 , and the screws enter the screw accommodating hole 43 from the discharge port through the guide rail 6 . The slotting is carried out, which improves the efficiency and saves the labor cost.
