Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a fast-retractable building construction plumb bob. Background Art

[0002] During the construction process, the verticality of vertical components such as walls and columns is an important indicator of the building structure's strength and bearing capacity. A plumb line is often used during construction to quickly test the verticality of vertical components.

[0003] The existing wire pendant mainly includes a winding reel, a sling, and a pendant, and the pendant is connected to a fixed block by the sling. When in use, the pendant can be lowered slowly by the winding reel or quickly by the gravity of the pendant. Compared with controlling the speed of the winding reel, the pendant can be lowered faster by gravity.

[0004] Although the pendant can be lowered by gravity to achieve a faster lowering speed, it is inevitable that there are still some shortcomings in the actual use process, such as the lack of a stop mechanism, so that after the pendant falls to the ground, the reel will lack a timely stop mechanism, resulting in the reel rotating along with the trend and releasing more rope length. In order to avoid such problems, a construction plumb line that can be quickly retracted is proposed to solve the existing problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a fast-retractable plumb bob for construction, which solves the problem that the winding reel may release more rope length due to rotation due to lack of a timely stopping mechanism.

[0006] To achieve the above purpose, the utility model is implemented through the following technical scheme: a fast-retractable construction plumb bob, comprising a winding box and a rotating rod, the rotating rod is rotatably arranged inside the winding box, the surface of the rotating rod is fixedly connected to the winding wheel, the surface of the winding wheel is wrapped with a sling, and one end of the sling passes through the winding box and slides to the bottom of the winding box, and the end of the sling extends to the bottom of the winding box and is fixedly connected to the pendant, and a mounting frame is slidably arranged at the bottom of the inner cavity of the winding box, and a rolling rod is rotatably connected between the front and rear sides of the inner cavity of the mounting frame through a bearing, the surface of the rotating rod is fixedly connected to a cone ring, the top of the mounting frame is fixedly connected to a handle inclined block used in combination with the cone ring, and the inclined surface of the handle inclined block and the cone surface of the cone ring are both provided with a number of rubber convex strips, and a fast winding mechanism is provided between the rotating rod and the winding box.

[0007] Preferably, the quick winding mechanism includes a rotating shaft, which is rotatably arranged on one side of the winding box, and the surface of the rotating shaft is fixedly connected to a first gear, one end of the rotating rod extends to the outside of the winding box, and the surface of the rotating rod is fixedly connected to a second gear meshing with the first gear and located outside the winding box, and one end of the rotating shaft is fixedly connected to an internal threaded sleeve via a bracket.

[0008] Preferably, a plug tube is fixedly connected to one side of the winding box, and a screw pin matched with the plug tube is internally threadedly connected to the internal threaded sleeve.

[0009] Preferably, a slide groove is provided at the bottom of the inner cavity of the winding box, a slider is slidably connected inside the slide groove, and the top of the slider is fixedly connected to the bottom of the mounting frame, and a return spring is fixedly connected between the slider and the slide groove.

[0010] Preferably, a pressure plate is fixedly connected to one side of the handle-belt inclined block, and the pressure plate slidably extends to the outside of the winding box.

[0011] Preferably, a handle is fixedly connected to the top of the winding box.

[0012] Beneficial Effects

[0013] The utility model provides a fast-retractable plumb bob for construction. Compared with the prior art, the utility model has the following beneficial effects: the utility model sets a mounting frame and a rolling rod in a reel box through elastic sliding, and sets a rubber convex strip between a cone ring and a handle-belted block, so that after the pendant falls to the ground due to gravity and the sling loses its tension, the mounting frame can be reset through elasticity, prompting the mounting frame to carry the handle-belted block to limit the cone ring, prompting the rotating rod and the reel to stop rotating in the same direction, and avoiding excessive length of the sling being released. Secondly, a fast reeling mechanism is set between the reel box and the rotating rod, so that the reeling of the sling can be faster and more convenient. Secondly, a screw pin and a plug are set between the internal thread sleeve and the reel box, so that the reeling state of the reel can be easily positioned. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a fast-retractable plumb bob for construction, comprising a winding box 1 and a rotating rod 2, the rotating rod 2 is rotatably arranged inside the winding box 1, a winding wheel 3 is fixedly connected to the surface of the rotating rod 2, a sling 4 is wound around the surface of the winding wheel 3, and one end of the sling 4 passes through the winding box 1 and slides to extend to the bottom of the winding box 1, the end of the sling 4 extending to the bottom of the winding box 1 is fixedly connected to a pendant 5, and a handle 18 is fixedly connected to the top of the winding box 1. As a detailed explanation: a guide ring used in conjunction with the sling 4 is fixedly arranged inside the winding box 1, and a wire hole used in conjunction with the sling 4 is opened at the bottom of the winding box 1.

[0022] Furthermore, in order to facilitate the rapid release of the line and avoid the problem of releasing too much length of the sling 4, a mounting frame 6 is slidably provided at the bottom of the inner cavity of the winding box 1, and a roller rod 7 is rotatably connected between the front and rear sides of the inner cavity of the mounting frame 6 through a bearing, a cone ring 8 is fixedly connected to the surface of the rotating rod 2, and a handle bevel 9 used in conjunction with the cone ring 8 is fixedly connected to the top of the mounting frame 6, and the inclined surface of the handle bevel block 9 and the cone surface of the cone ring 8 are both provided with a number of rubber convex strips 10, a pressure plate 17 is fixedly connected to one side of the handle bevel block 9, and the pressure plate 17 slidably extends to the outside of the winding box 1, a slide groove 14 is provided at the bottom of the inner cavity of the winding box 1, a slider 15 is slidably connected to the inside of the slide groove 14, and the top of the slider 15 is fixedly connected to the bottom of the mounting frame 6, and a return spring 16 is fixedly connected between the slider 15 and the slide groove 14.

[0023] Further, in order to facilitate subsequent rapid winding, a rapid winding mechanism 11 is provided between the rotating rod 2 and the winding box 1, and the rapid winding mechanism 11 includes a rotating shaft 111, the rotating shaft 111 is rotatably provided on one side of the winding box 1, a first gear 112 is fixedly connected to the surface of the rotating shaft 111, one end of the rotating rod 2 extends to the outside of the winding box 1, a second gear 113 meshing with the first gear 112 is fixedly connected to the surface of the rotating rod 2 and located outside the winding box 1, and one end of the rotating shaft 111 is fixedly connected to an internal threaded sleeve 114 through a bracket;
