Positioning device

Abstract

The invention relates to the technical field of machines, and discloses a positioning device. The positioning device comprises a body and one or more positioning units, a first sliding groove is formed in the body, the positioning unit is slidably connected with the first sliding groove through a connecting piece, a second sliding groove is formed in the positioning unit, one or more identification pieces are slidably arranged in the second sliding groove, and the connecting piece and the identification pieces each have a position locking state and a position unlocking state capable of being mutually switched. According to the positioning device provided by the embodiment of the invention, a worker can easily and accurately project a plurality of mounting holes in to-be-mounted mechanismssuch as street codes to high mounting positions at a long distance from the ground by applying the positioning device, a traditional mode that the to-be-mounted mechanisms are directly hoisted to thehigh positions to be subjected to aligning drilling is substituted, the time and energy consumed during positioning operation by the worker can be reduced, and working safety of the worker can be further effectively improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a positioning device. Background technique [0002] Street yards are usually used for fixing parts when low-voltage lines are erected on concrete poles. Street codes usually include multiple mounting holes, and expansion screws can be used to lock the street code on the wall, so as to figure 1 Take the structure shown as an example, the traditional operation steps are: [0003] 1. The operator stands on the bamboo ladder and attaches the street yard bracket weighing about 12KG, about 75CM long and 25CM wide to the wall about 4-5 meters above the ground, and fixes the four installation holes of the street yard on the wall Make a mark to get 4 holes. [0004] 2. After marking the fixed point, put the street code from the wall to the ground, drill the 4 holes on the wall with an impact drill, install the expansion screws on the 4 holes respectively, and put the nuts of the expa...
