Service HotlineT-bolt, the European standard is called hammer bolt, the material is carbon steel, the surface is galvanized or nickel-plated, the T-bolt can be directly put into the groove of the aluminum profile, and it can be automatically positioned and locked during the installation process. Used in conjunction with the blue nut, it is a standard matching connector when installing corner fittings. It can be selected and used according to the profile groove width and different series of profiles. When the T-bolts on the market are installed with the installation channel, the bolts need to be placed into the channel from the port of the channel, and then tightened when moving to the designated position. The bolts are easy to rotate during installation, and the connection is not tight. Therefore, it is necessary to propose a mounting structure that uses T-bolts and grooves.
Pin riveting is an important procedure in the production process. At first, people used manual work, which has low production efficiency, high production cost, and high defect rate of products produced. Later, a pin riveting machine appeared. The pin riveting machine is a For riveting and pinning of hardware products, the pin riveting machine can complete the operation of pin loading and riveting pins, and the pin riveting machine reduces the process of pin loading and riveting pins in the hardware production process. However, its structural design is unreasonable and the operation is very inconvenient
drilling and tapping screw, more specifically, refers to a drilling and tapping screw that can be closely connected to an object without clearance. Screws usually use a screw design to achieve the purpose of tightening, or adjusting distance, or moving or transmitting power. Among them, it is the most common for tightening, and the screws generally used for tightening also usually have The combined function of self-drilling, tapping and locking can achieve the purpose of its tight fit. Known drilling and tapping screws are such as
In addition, in the prior art, rivets are also used to riveted screws on metal plates. The rivets are nail-shaped objects with a cap at one end. In riveting, the riveted parts are connected by their own deformation or interference. When using rivets, it is necessary to set moderately sized positioning holes in the corresponding positions of the two metal plates, and the rivets directly penetrate into the positioning holes and then riveted. Because this riveting method does not require welding, it will leave a hole on the back of the metal plate. Therefore, in the prior art, the surfaces of the two metal plates after riveting are covered with a layer of smooth metal skin to cover the riveting marks, which will also increase the overall cost, including metal The cost of the skin and the increase in the manufacturing process, while the riveting process is limited, the connection between all metal plates cannot be universal.
A rivet is a nail-shaped object with a cap on one end: in riveting, the parts being riveted are joined by their own deformation or by interference. There are many types of rivets, and they are informal. However, the two ends of conventional rivets are concentric, which is not suitable for special occasions.
