Service HotlineT-slot convenient bolt that can be used for the middle port of the T-slot and directly realizes the assembly and tightening of the bolt and the nut. Technical Background At present, the bolts for T-slots are assembled from two side ports of the T-slots. When the length of the T-slot is long, it is time-consuming and laborious to install from the side port to the center port at the designated position. In addition, the two side ports of the T-slot are often blocked by other components, and the bolts for the T-slot cannot be installed or removed without disassembling other components. The utility model makes some improvements to the prior art. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a T-slot convenient bolt with simple structure and convenient mounting and dismounting for the current situation that the existing T-slot bolts are inconvenient to install and disassemble.
Fasteners are a class of mechanical parts that are used for fastening connections and are widely used. It is used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic and other industries, in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments And supplies, etc., you can see all kinds of fasteners, which are widely used mechanical basic parts. In the fields of listed rails, construction machinery, etc., due to the harsh application environment, the requirements for fasteners are more stringent. If the fasteners are loosened, it may lead to serious consequences, resulting in a large amount of property damage, even serious life cost.
In view of the above situation, the technical problem to be solved by Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a self-expanding semi-solid installation rivet, the purpose is to solve the existing connection between plastic shells, lightweight plates, insulating materials, circuit boards, or any other In the case of thin, light-weight materials, the grip and bonding force of the rivet itself on the mounting surface is weaker than that of the rivets that are screwed and installed by manual operation. The rivet structure needs to be improved and strengthened when the material is installed.
Thread Code Broadcast Coarse Thread Series UNC Fine Thread Series UNF Extra Fine Thread Series UNEF Fixed Pitch Series UN Marking Method Broadcast Marking Method: Thread Diameter - Number of Threads per Inch Serial Code - Accuracy Grade Example: Coarse Thread Series 3/8—16 UNC— 2A Fine pitch series 3/8—24 UNF—2A Extra fine pitch series 3/8—32 UNEF—2A Fixed pitch series 3/8—20 UN—2A The first digit 3/8 indicates the outer diameter of the thread, in inches , to convert to metric unit mm, multiply by 25.4, that is, 3/8×25.4=9.525mm; the second and third digits 16, 24, 32, 20 are the number of teeth per inch (the number of teeth on the 25.4mm length); The text code UNC, UNF, UNEF, UN after the third digit is the series code, and the last two digits 2A are the precision grade. UNC: Unified Coarse Thread.
The t-bolt can be directly put into the groove of the aluminum profile. It can be automatically positioned and locked during the installation process. It is often used in conjunction with the flange nut. profiles to choose from. T-bolts are movable anchor bolts. The existing t-bolt is easy to rotate and swing in the slot during use, which brings some inconvenience to the use of the t-bolt.
