Embodiment

[0019] A kind of screw wrench that can be disassembled smoothly of the present invention, as figure 1 As shown, including center column 3, hex nut 2, upper wrench set 1, lower wrench set 6, washer 5 and wrench rod 4;

[0020] The sidewalls at the upper and lower ends of the central column 3 are respectively processed with threaded sections with opposite thread directions. The external thread of the threaded section at the lower end of the central column 3 matches the internal thread of the threaded hole of the assembly part, and the length of the threaded section at the lower end of the central column 3 is shorter than that of the assembly part. The depth of threaded hole, the middle part of central column 3 is the connection section of regular hexagon, and the outer diameter of threaded section of central column 3 lower ends is greater than the outer diameter of the circumscribed circle of central column 3 middle part connection section; The threads of the threaded section at...

Abstract

The invention relates to a thread wrench with a smooth disassembling and assembling effect, and belongs to the field of thread assembly. The thread wrench comprises a central column, a hexagonal nut and wrench sockets, thread sections with opposite thread directions are machined on the side walls of the upper end and the lower end of the central column correspondingly, the lower-end thread of thecentral column is screwed into a thread hole of an upper assembly part, the lower wrench socket sleeving the central column and the upper end surface of the upper assembly part are tightly pressed through the hexagonal nut connected with the upper end of the central column, the threads on the two assembly parts are tightened through the lower wrench socket under the action of the friction force between the lower end surface of the lower wrench socket and the upper end surface of the upper assembly part, after the assembly is completed, the hexagonal nut is loosened, the pressing force betweenthe lower wrench socket and the upper end surface of the upper assembly part is removed so that the central column can be easily disassembled. The thread wrench has the advantages that the structure is simple, the assembly is convenient, reliable assembly and disassembly of the two thread butt joint parts are realized, and the wrench tool can be smoothly disassembled.

Description

technical field [0001] The invention relates to a threaded wrench which can be disassembled and assembled smoothly, and belongs to the field of thread assembly. Background technique [0002] A certain product includes an upper cone part and a lower cylinder part; the upper end of the upper cone part is processed with a threaded hole downward, the outer wall of the lower end of the upper cone part is processed with external threads, and the threaded hole at the upper end of the upper cone part is connected with the outer surface of the lower end. The threads have the same thread direction; the upper end of the lower cylindrical part is provided with a threaded hole matching the threaded section at the lower end of the upper cone part; the upper cone part is threadedly assembled with the lower cylindrical part. Due to the limitation of the cone shape of the upper cone, the outer wall of the upper cone cannot be effectively clamped, so a threaded wrench can only be connected in...
