Service HotlineAt present, in the standard cabinets of computers, networks, automation, etc., to fix the equipment in the cabinet, it needs to be fixed by using fasteners. The nuts in the existing fasteners are ordinary nuts, which are internal card structures. , there are the following shortcomings: 1. The installation and disassembly are complicated, and a large amount of force is required to insert the nut during installation and disassembly, and the nut cannot be installed and disassembled at all due to the processing error of each nut; 2. After the nut is used for a long time, the nut The card edge will have slack problem, which will affect the use; 3. Installation or disassembly is easy to cause problems such as falling, which may cause electrical short circuit, etc., and there are potential safety hazards; 4. The efficiency of equipment installation is low.
4. Manufacturing and assembly Due to the limitations of manufacturing technology and accuracy, there are sharp corners on the edge of the thread or the dimensional coordination between parts is not coordinated. During the initial assembly, the screw-in and screw-out torque may fluctuate or fluctuate to a certain extent. After a certain number of running-in, more accurate reusability characteristics of the lock nut can be obtained.
The gasket side of the above-mentioned nut assembly is in contact with the mounting surface. When the nut is tightened, the gasket squeezes the outer cone surface to make it shrink, and the cone tip faces the same direction as the nut, thereby preventing the nut from tightening, so that the nut fixing effect is not good, and at the same time When multiple nuts need to be superimposed and fixed, two adjacent nuts cannot interact with each other, resulting in poor fixing effect.
T-bolt with a spring, used for undercutting the opening of the outer closed cavity, including a head and a rod part connected in one piece, and also including a strip spacer, a spring and a pull rod, and the length of the strip spacer is greater than The opening, the connecting part of the head and the rod part are set as polygonal anti-rotation blocks, and the strip-shaped spacer is provided with anti-rotation holes for inserting the anti-rotation blocks, and the shape and size of the anti-rotation holes are the same as The size of the anti-rotation hole is smaller than that of the head; the spring is threadedly matched with the rod part, and is fixedly connected with the pull rod, and the pull rod moves away from the rod part along the axial direction of the rod part One side of the head extends. The utility model can be easily and reliably buckled in the opening of the airtight cavity, thereby facilitating the installation and connection of external parts.
In order to meet the needs of different assembled installation components, there are also hand-tightening methods for tightening the screws, but in actual use, ordinary manual screws can easily cause hand pain to the user, and the operation is extremely inconvenient; at the same time, due to tightening The contact area between the screw and the installation component is too small. If the user exerts too much force, the uneven force per unit area of the installation component will cause deformation and depression, which will affect the use. Therefore, a manual screw is proposed to solve the above problems.
