DETAILED DESCRIPTION

[0031] The technical solutions of the patent will be further described in detail below in combination with specific embodiments.

[0032] The embodiments of the patent will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the patent, and cannot be understood as a limitation of the patent.

[0033] Please refer to Figure 1 The embodiment provides a measuring line plummet for building construction, which comprises a line plummet body 10, a rope body 20, a cover body 30, a winding wheel 60, a rotating shaft 70 and a limiting part 80. The line plummet body 10 is provided with a groove 101 on one side. The rotating shaft 70 is rotatably installed in the groove 101. The rope body 20 and the winding wheel 60 are provided in pairs. The two winding wheels 60 are fixedly installed outside the rotating shaft 70. The two winding wheels 60 are deviated from the center of gravity of the line plummet body 10. One end of the two rope bodies 20 is connected with the cover body 30, and the other end is respectively wound outside the two winding wheels 60. The limiting part 80 is movably arranged in the groove 101. When the line plummet body 10 overturns, the limiting part 80 can slide in the groove 101 under the action of gravity, so as to limit the rotation of the rotating shaft 70.

[0034] In use, the cover body 30 can be held by hand, and the line pendant body 10 is loosened. At this time, the two groups of winding wheels 60 are subjected to the tension of the two groups of rope bodies 20, and then drive the rotation of the rotating shaft 70. The two groups of rope bodies 20 are unwound from the corresponding winding wheels 60, and the line pendant body 10 can be lowered along one side of the wall. By operating the cover body 30 to flip, at this time, since the two groups of winding wheels 60 are offset from the center of gravity of the line pendant body 10, when the cover body 30 is flipped, one group of rope bodies 20 is subjected to force, and the other group of rope bodies 20 is not subjected to force. The group of rope bodies 20 subjected to force can drive the line pendant body 10 to overturn. At this time, the limiting part 80 located in the groove 101 is adaptively slid under the action of gravity to limit the rotation of the rotating shaft 70, thereby limiting the rotation of the winding wheel 60, so that the rope body 20 stops unwinding, and the line pendant body 10 stops at a certain position on one side of the wall.

The first ring plate 802 is provided with a plurality of first protrusions 801 uniformly distributed on one side. The inner wall of the groove 101 is provided with a guide rail 805. The end of the connecting rod 803 away from the first ring plate 802 is slidably connected with the guide rail 805 through a sliding block 804.

[0036] When the line pendant body 10 overturns, the first ring plate 802 can slide along the outside of the rotating shaft 70 to the second ring plate 702 through the sliding connection between the sliding block 804 and the guide rail 805, so that the first protrusions 801 are embedded in the gaps between the second protrusions 701, and the relative locking between the first ring plate 802 and the second ring plate 702 is realized. After the second ring plate 702 is locked, the rotation of the rotating shaft 70 is limited, and the winding wheel 60 stops unwinding the rope body 20. The line pendant body 10 remains stationary at a certain position on the outside of the wall.

[0037] Please refer to Figure 1 In one embodiment, the groove 101 is further provided with a rotating part 90.
