Summary of information:We have more than ten years of production experience in the screw industry. The main products are: six-star handle star ...

In the prior art, the beams used for installing the curtain wall are mainly divided into two types: closed-cavity structure and open structure, and angle aluminum connection is mainly used for the connection between the beam and the column. As far as the beam of the closed-cavity structure is concerned, after the angle aluminum is used to connect, there are open bolts on both ends of the upper surface of the beam, and the aesthetic performance is extremely poor. As far as the beam of the open structure is concerned, in the actual connection, first fix one corner of the angle aluminum to the beam, and then connect the other corner of the angle aluminum to the column; due to the limited operating space in the beam of the open structure, the angle aluminum is not It is easy and accurate to install, and it takes a lot of time to install; and when the curtain wall panel is heavy, the beam will be twisted, causing the gusset of the opening part of the beam to fall. In addition, due to the limitation of the opening structure itself (an additional gusset or clasp), the aluminum content of the beam is relatively heavy, and the manufacturing cost is high.

In the past production, gaskets were generally obtained from two channels: first, standard gaskets were mostly purchased from the market, and the cost was high; non-standard gaskets, due to the small demand, required separate tooling and molds, which were expensive and long production cycle. It is difficult to purchase; Second, the plate is purchased by the enterprise, and then the washer is formed by the automatic cutting machine. Because the cut nodules and cut marks produced by flame cutting do not meet the requirements for use, the inner and outer diameters need to be reserved 2 ~3mm machining allowance, and then finish the outer diameter and inner diameter by lathe.

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide an improved lock nut to solve the problem that the production technology of the prior art products is too complicated. For realizing the above-mentioned purpose, Guangdong Yueluo Hardware Industry Co., Ltd. adopts following technical scheme—a kind of locking nut, which comprises that the bottom of the nut is a circle, the middle part is a hexagon, and the top is a circle, and there are bolts in the center.

The application range of the oil pump is very wide. When it is used, the oil pump needs to be assembled. During the assembly process, when the pin is driven into the pin hole, it is generally held by the operator with a hammer, and then aiming at the top of the pin to press. Into the hole, due to the relatively high tolerance requirements for the depth of the pin pressing and the side clearance (the gap between the pin and the groove wall), the traditional operation method not only causes a high rejection rate and a long training time for personnel, but also The slow processing speed affects the production efficiency.

In order to overcome the above problems, Guangdong Yueluo Hardware Industry Co., Ltd. provides a screw that can be quickly installed and removed. Using the principle of lever, press the handle downward, and the screw can form a backward force through the connecting piece. Press the screw and nut tightly; lift the handle, the screw forms a forward force, and the screw can be removed. Thus, the time and manpower for screwing during installation and disassembly are reduced. The solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is that the entire screw includes a screw rod, a nut, a connecting piece, a circlip, a positioning pin, a small shaft, a fixed piece, a base, and a handle; the screw is connected by the small shaft at the upper end. At the upper end of the connecting piece, the handle is connected to the lower end of the connecting piece, and the front end of the handle is connected to the base fixing piece through a positioning pin. There are gaps at both ends of the small shaft, and the small shaft is installed through the circlip. The front end of the handle can only be rotated on the positioning pin. Due to the lever principle, when the handle is pressed down, it will drive the screw at the front end of the connecting piece, so that the screw generates a backward force and tightens the screw and the nut. On the contrary, when the handle is pulled up, the screw generates a forward force, so that the screw can be easily removed. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is that the quick-opening screw saves the time and labor of repeatedly twisting the nut during installation and disassembly. The installation and removal process is simple.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: caps and caps, plum blossom screws, cap-shaped decorative cap nuts, 201 stainless steel and other products, we can provide you with suitable fastening products piece solution.
