Service HotlineThe purpose of Yueluo is to provide a screw with a plurality of threads continuously coiled in a helical shape formed on its shank; wherein the shank is provided with a protruding cutting portion at the front section with threads toward the tip, for the purpose of providing the screw. The front section is screwed into the object to successfully complete the stage of cutting and rapid chip removal, and the rod part is provided with a concave cutting part at the rear section with threads toward the head, for the rear section of the rod to be introduced into the object. , so that the work of the stage of cutting and collecting chips can be successfully completed; so that the screw can achieve multiple functions such as labor-saving cutting, smooth and rapid chip removal and chip collection during the locking process.
Locking of screws belongs to the prior art. Or by means of a visual method (X-ray control) a more or less complex aiming device is inserted into the transverse hole of the screw. In both cases a certain misalignment is unavoidable, ie the screw may not be coaxial with the central axis of the transverse hole and deviate from it by a certain value. In order for the locking screw to pass into and through the transverse hole despite this misalignment, the outer diameter of the screw is determined to be a size smaller than the diameter of the transverse hole. If the aiming is not maintained within this small dimension value, the locking screw can pass through the transverse hole without difficulty despite the aiming error. Now, however, the locking screw has a certain clearance relative to the transverse hole due to the determination of a smaller size value.
Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, etc. , chemical industry, instruments and supplies, etc., you can see all kinds of fasteners, which are the most widely used mechanical basic parts. It is characterized by a wide variety of specifications, different performance uses, and a very high degree of standardization, serialization and generalization. Therefore, some people also refer to a type of fasteners that have been standardized as standard fasteners, or simply referred to as standard parts.
Guangdong Yueluo Hardware Industry Co., Ltd. relates to a square nut fastener for cable bridge installation, which is characterized in that it includes an upper plate body and a U-shaped jacket, and the upper plate body is provided with a downwardly protruding connecting cylinder, The two side plates of the U-shaped jacket are connected to the connecting cylinder, and the center line of the two side plates is located on the center line in the length direction of the upper plate body; the bottom of the U-shaped jacket is a wave-shaped elastic plate, which is a wave-shaped elastic plate It is fixedly connected on the two side plates, and the space enclosed by the two side plates of the U-shaped jacket, the wave-shaped elastic plate and the bottom of the connecting cylinder is the installation position of the square nut. Guangdong Yueluo Hardware Industry Co., Ltd. has a simple and reasonable structure, and is extremely convenient and flexible to operate; it does not occupy the bottom space of the C-shaped steel after installation, which increases the variety of installation, and can be applied to square nuts of different thicknesses, and the installation is firm.
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.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: rock climbing expansion screws, complete specifications and models of washers, wood screws, account book screws, rivets and other products, we can provide you with suitable fasteners for you solution.
