Abstract

The invention relates to the field of tube connecting tools, and discloses a manual operating tool for inserted connection of slotted head steel tubes. The manual operating tool comprises a handle, a handle head, a box body, a rack shaft, a gear, a chuck body, a chuck, a friction plate, a nut and an assembling and disassembling sleeve assembly, wherein the gear is arranged in a transverse hole I of the box body; the rack shaft penetrates in the box body and is slidably arranged in the axial hole I; a toothed groove is formed in one end of the rack shaft; a side surface of the toothed groove faces the gear; a small end surface of the chuck is arranged in a transverse hole II of the chuck body in a sliding fit manner; a pedal is arranged in the groove; an axial hole III is formed in the pedal; after extending out of the axial hole I of the box body, the rack shaft penetrates through the axial hole II and the axial hole III; outer threads are arranged at the outermost end of the rack shaft; the outermost end of the rack shaft is fastened through the nut; and the handle is fixedly connected with the handle head. By the special tool of an inserted connection type connector, labor intensity of tube installation personnel is reduced, and tube connection efficiency is improved; and meanwhile, the special tool for the inserted connection type connector is safe and convenient when used.

Description

technical field [0001] The invention belongs to the field of pipeline connection tools, and in particular relates to a special tool for socket-head steel pipe plug-in connectors. Background technique [0002] When the grooved head steel pipe is connected and disassembled with a plug-in connector, only a certain axial thrust can be applied to insert the pipe grooved head into the connector to complete the connection of the pipe; or pull the pipe grooved head out of the connector out to realize the disassembly of the pipe. This axial thrust may be applied by an automated pipelaying mechanical device or by a hand-operated tool. This hand-operated tool is used for laying and withdrawing pipelines manually. In order to prevent theft and improve safety, when the grooved steel pipe adopts a plug-in connector, ordinary tools cannot be used, but special tools must be used for operation. Contents of the invention [0003] In view of the need for tools required for manual operatio...
