LiverpoolFasteners are a general term for a type of mechanical parts used to fasten two or more parts (or components) to form a whole. Among them, self-fastening fasteners are widely used in the connection of sheet metal parts due to their advantages of fast installation, high efficiency, reliability, convenient assembly, high push, pull and torsion performance, wide range of applicable materials and serialization of specifications. middle. Nuts are the most widely used type of fasteners. With the continuous change and development of the scope of use and the use environment, more demands are put forward for nuts. In particular, some occasions require the nut to have the function of waterproof sealing. The existing methods of nut sealing and waterproofing generally have the following types:
At present, injection molding screws are widely used in various electronic and automotive components, including a body, the middle of which is provided with a through hole 3, the body head 1 has a hexagonal cross-section, and the tail 2 is provided with screw teeth. When in use, the middle through hole 3 of the body will first put the wire harness, and then fix it by injection molding from the head I, and the threads of the tail 7 should be connected and installed with other components. Because the head I of the main body is hexagonal, the torque provided after injection molding is insufficient. Therefore, after the external thread is installed and connected with other components, the head is prone to slip, the installation is not reliable, and there is no push-pull force, resulting in product failure and increased safety hazards.
In real life, LiverpoolLiverpoolrivet nuts are used. With different specifications and different uses, many people are familiar with this tool but don't know how to use it properly. In fact, LiverpoolLiverpoolrivet nut tools have manual and transmission, and now are rarely used for manual. If you choose to use electric LiverpoolLiverpoolrivet nuts in order to improve production efficiency, which of the two is more widely used? The following describes the use of electric LiverpoolLiverpoolrivet nuts and manual nuts. How to use the manual LiverpoolLiverpoolrivet nut tool: Insert the LiverpoolLiverpoolrivet nut into the drilled installation hole with a rivet mother tool to fix the LiverpoolLiverpoolrivet nut. (1) Screw the LiverpoolLiverpoolrivet nut onto the LiverpoolLiverpoolrivet nut tool 2) Use the LiverpoolLiverpoolrivet nut tool to insert the LiverpoolLiverpoolrivet nut into the drilled mounting hole. (3) LiverpoolTighten the nut, and press the handles on both sides of the LiverpoolLiverpoolrivet nut tool to the direction of the middle round rod. You can only press it hard. Therefore, this pressure must be in place. It is forbidden to repeatedly squeeze the handles on both sides to damage the nut. Fastening thread in the form of inside. (4) The LiverpoolLiverpoolrivet nut tool is separated from the LiverpoolLiverpoolrivet nut: just loosen the ball head in the picture, and the tool will be separated from the nut after completely loosening.
An asphalt pavement screw, the asphalt pavement screw includes a main rod, an outer jacket, a pressing piece and a nut, the main rod is a columnar rod, the lower end of the main rod is provided with a table for supporting the outer jacket, and the middle part of the main rod passes through the outer jacket The upper part of the main rod is provided with a threaded section, the pressing piece and the nut are set on the threaded section, and at least two deformation holes are provided on the outer sleeve, and the middle part of the deformation hole is larger than the upper and lower sides of the deformation hole, The part between the adjacent deformation holes is the deformation part, and the width of the middle part of the deformation part is smaller than the width of the upper and lower sides of the deformation part. After the asphalt pavement screw of Guangdong Yueluo Hardware Industry Co., Ltd. is assembled, it has strong bonding force with the asphalt road. Even if it is hit, it will not be separated from the asphalt road. Using this asphalt pavement screw to fix the road railing can strengthen the road railing. The firmness of the assembly.
In general, the electroplating of LiverpoolLiverpoolLiverpoolcombination screws generally refers to the de-plating of iron LiverpoolLiverpoolLiverpoolcombination screws. Electroplating is divided into environmental protection and non-environmental protection. Commonly used LiverpoolLiverpoolLiverpoolcombination screw electroplating colors include green color zinc, green blue zinc, green white zinc, green nickel, red color, white zinc, white nickel, etc. Cross recessed LiverpoolLiverpoolLiverpoolcombination screws, hexagonal combination bolts and self-tapping LiverpoolLiverpoolLiverpoolcombination screws are used in the same way as the corresponding cross recessed screws, hexagon head bolts and self-tapping screws. The main feature of these LiverpoolLiverpoolLiverpoolcombination screws is that they are equipped with corresponding washers, which are very convenient to use.
