Building construction plummet capable of conveniently taking up and paying off winding line

Abstract

The invention discloses a building construction plummet capable of conveniently taking up and paying off a winding line. The plummet comprises a cylindrical installation shell, a plummet body is mounted on the lower portion of the cylindrical installation shell, a first circular opening is formed in the surface of the right side of the cylindrical installation shell, a first rotating bearing is embedded into the first circular opening, a second rotating bearing matched with the first rotating bearing is arranged on the surface of the inner left side of the cylindrical installation shell, a horizontal rotating shaft overlapped with the first rotating bearing and the second rotating bearing is arranged in the cylindrical installation shell, a line wheel sleeves the surface of the horizontalrotating shaft and is positioned in the cylindrical installation shell, a circular opening is formed in the center of the lower surface of the cylindrical installation shell, and the winding line fixedly connected with the upper surface of the plummet body is wound on the line wheel. The plummet has the advantages that when the plummet is used, the plummet is more stably placed downwards by the aid of the line wheel, convenient to operate, safer and not easy to slip out of the hand.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a building construction wire sinker that is convenient for retracting and winding wires. Background technique [0002] Line pendant, also called plumb bob, refers to a conical object made of metal (iron, steel, copper, etc.), mainly used for measuring the verticality of objects, and is more common in construction projects. [0003] In the existing technology, the application number: 201720202025.9, in the patent named adjustable line pendant, which improves the work efficiency of using the line pendant for measurement, reduces the adjustment time during the line pendant measurement process, and improves the measurement accuracy. During the use of the wire pendant, the cone head can be replaced in time according to the wear of the cone head, without the need to replace the wire pendant as a whole, which reduces the cost of use. [0004] However, in the process of using the li...

Problems solved by technology

[0004] However, in the process of using the line pendant in the above-mentioned patent, it is necessary to manually grasp the line of the line pendant and lower it. There are also independent pins for fixing, but the independent pins are easy to lose, and the process of aligning and fixing is cumbersome, and when aligning, one hand is required to fix the line drop, and the other hand is used for fixing independently, which is extremely inconvenient
