Description

Non-magnetic attraction locking sleeve

Technical Field

The present invention relates to a locking sleeve, and more particularly to a non-magnetic locking sleeve.

Background

With the development of industrial technology, locking assemblies such as bolts, nuts and screws are generally applied to combined structures of various products, and locking sleeves are widely applied to the assembly and disassembly operations of the locking assemblies with hexagonal heads; however, the hexagonal heads of the locking assemblies have different dimensional tolerances, and in order to match the heads with different dimensional tolerances for locking, the locking space for accommodating the hexagonal head in the locking sleeve has a certain tolerance, so that the locking space cannot be tightly positioned with the hexagonal head, and the locking assembly must be pressed tightly in the locking process, otherwise, the locking assembly is easy to slip, and the locking effect is poor.

Therefore, as shown in fig. 1, the locking sleeve 1 includes a sleeve body 11 having a locking hole 113, and a magnetic member 12 disposed in the sleeve body 11, so that when a locking assembly 13 is locked, and the locking assembly 13 is inserted into the locking hole 113, the magnetic member 12 is attracted by magnetic force to generate a stable positioning effect, thereby facilitating subsequent locking operations; however, after practical use, it is found that the magnetic attraction piece 12 only has an effect on the metal locking component, but obviously has no effect on the non-metal locking component, and in addition, metal debris generated in the locking process is easily attached to the magnetic attraction piece 12, so that the surface of the magnetic attraction piece 12 is covered by the metal debris, thereby affecting the magnetic attraction effect of the magnetic attraction piece 12, which needs to be improved.

Referring to fig. 2, another locking sleeve 2 for locking a non-metallic locking assembly is provided, in which the locking sleeve 2 includes a sleeve body 21 having a locking hole 213, and a C-shaped buckle 22 disposed in the sleeve body 21, wherein the periphery of the C-shaped buckle 22 is a smooth surface, and the locking hole 213 is formed by connecting and enclosing a plurality of peripheral walls 214; therefore, when a locking component 23 is inserted into the locking hole 213, when the C-shaped buckle 22 is pushed, the locking component 23 is held and positioned by the elastic restoring force generated by the C-shaped buckle 22, however, although the C-shaped buckle 22 has a certain holding force, the C-shaped buckle 22 and the locking component 23 are in single-point contact, and some tiny oil films are attached to the surface of the locking component 23, so the locking effect of the C-shaped buckle 22 is limited, and in addition, the locking hole 213 is formed by vertically connecting the peripheral walls 214, in view of the problem of manufacturing tolerance of the locking component 23, the locking component 23 cannot be tightly attached to the peripheral walls 214 of the locking hole 213, so that the locking component 23 is easily shaken when being inserted and positioned, which is also to be improved.
