[0002] A plumb bob is a cone-shaped object made of cast metal. It is mainly used to measure the verticality of an object. Since there is a certain distance between the plumb bob and the wall, it is necessary to use a ruler to make it easier to measure the verticality of the wall.

[0003] Existing plumb bobs used in construction have certain drawbacks. First, when used in construction, the plumb bob often comes into contact with cement mortar or bricks, which can easily cause wear and corrosion, thus affecting its use. Also, when not in use, the plumb bob can easily roll when placed at an angle, and its direct contact with the ground can also cause corrosion, which can easily lead to damage to the plumb bob. Utility Model Content

[0004] The purpose of this invention is to provide a plumb bob for construction, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a plumb bob for construction, comprising a main body of a plumb bob and a take-up device, wherein a connecting rope is provided between the main body of the plumb bob and the take-up device, a hammer tip structure is provided at the center of the bottom end of the main body of the plumb bob, a protective structure is provided at the lower end of the main body of the plumb bob, and the hammer tip structure is located between the protective structures, wherein the protective structure is connected to the interior of the main body of the plumb bob.

[0006] The hammer tip structure includes a connecting hole, which is located at the center of the bottom of the hammer body. A connecting post is provided inside the connecting hole, and a fastening screw passes through the connecting post. The bottom end of the connecting post is provided with the hammer tip. The connecting post is fixed to the hammer tip by the fastening screw.

[0007] Furthermore, the connecting post is threadedly connected to the connecting hole, and the connecting post is located at the exact center of the top of the hammer tip.

[0008] Furthermore, the protective structure includes three reserved slots, which are formed on the frustum of the main body of the hammer. Each reserved slot is provided with a connecting strip inside. One end of the connecting strip is located inside the upper part of the connecting hole, and the other end of the connecting strip is welded with a protective plate. Each of the three protective plates is provided with a support foot at its bottom end, and a telescopic spring is provided between the three protective plates.

[0009] Furthermore, a hinge is provided at one end of the connecting strip near the protective plate, and the connecting strip is connected to the reserved slot of the main body of the counterweight through the hinge.

[0010] Furthermore, the reserved slots and protective plates are evenly arranged on the main body of the hammer, and the center of gravity of the protective structure is on the same vertical line as the center of gravity of the main body of the hammer.

[0011] Furthermore, the connecting rope is connected to the center of the top of the main body of the hammer, and the connecting rope is wound inside the take-up device.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 The present invention provides a technical solution: a plumb bob for construction, comprising a weight body 1 and a take-up device 3, a connecting rope 2 between the weight body 1 and the take-up device 3, a hammer tip structure 4 at the bottom center of the weight body 1, a protective structure 5 at the lower end of the weight body 1, and the hammer tip structure 4 located between the protective structures 5, and the protective structures 5 connected to the interior of the weight body 1.

[0023] The hammer tip structure 4 includes a connecting hole 402, which is located at the center of the bottom end of the main body 1 of the hammer. A connecting post 401 is provided inside the connecting hole 402, and a fastening screw 404 passes through the connecting post 401. The bottom end of the connecting post 401 is provided with a hammer tip 403. The connecting post 401 is fixed to the hammer tip 403 by the fastening screw 404.

[0024] In this embodiment, the connecting post 401 is threadedly connected to the connecting hole 402. The connecting post 401 is located at the center of the top of the hammer tip 403. When the hammer tip 403 is worn or corroded, the hammer tip 403 can be replaced to prevent the center of gravity of the hammer tip 403 from always being on the same vertical line as the center of gravity of the hammer body 1, and to ensure that the end of the hammer tip 403 and the end of the connecting rope 2 are on the same vertical line.

[0025] In this embodiment, the protective structure 5 includes three reserved slots 501. The three reserved slots 501 are formed on the frustum surface of the main body 1. Each reserved slot 501 has a connecting strip 502 inside it. One end of the connecting strip 502 is located at the upper end of the connecting hole 402, and the other end of the connecting strip 502 is welded to a protective plate 503. Each of the three protective plates 503 has a support foot 504 at its bottom end, and a coil of telescopic spring 505 is arranged between the three protective plates 503. A hinge is provided on one end of the connecting strip 502 near the protective plate 503, and the connecting strip 502 is connected to the reserved slot 501 of the main body 1 via the hinge. The groove 501 and the protective plate 503 are evenly arranged on the main body of the hammer 1, and the center of gravity of the protective structure 5 is on the same vertical line as the center of gravity of the main body of the hammer 1. When the hammer tip 403 protrudes from between the protective plates 503, the verticality or horizontality of the object can be measured. When the hammer tip 403 is screwed into the hammer body 1, the connecting column 401 pushes the connecting strip 502 to make the protective plate 503 move closer to the center. The protective plate 503 can protect the hammer tip 403 and reduce damage or wear to the hammer tip 403. The support foot 504 can support the main body of the hammer and prevent the main body of the hammer from tipping over.

[0026] In addition, the connecting rope 2 is connected to the top center of the main body of the counterweight 1, and the connecting rope 2 is wrapped inside the take-up device 3.

[0027] It should be noted that when measuring verticality and horizontality using a plumb line during construction, the main body 1 of the plumb bob is placed near the surface to be measured. The connecting rope 2 in the take-up device 3 is extended, causing the main body 1 of the plumb bob to be lowered. When the main body 1 of the plumb bob is stationary, the vertical line can be determined by the connecting rope 2. The verticality of the wall can be determined by measuring the distance between the vertical line and the wall using a ruler. One side of a right-angle ruler is aligned with the vertical line, and the other side of the right-angle ruler is the horizontal line. This allows for the measurement of horizontality and verticality in conjunction with other measuring tools. During measurement, the tip 403 of the plumb bob is rotated outwards so that it protrudes between the support legs 504. The center of gravity of the protective structure 5 and the center of gravity of the main body 1 are on the same vertical line. At this time, the tip of the plumb bob 403 is on the same line as the main body 1. If the tip 403 of the plumb bob experiences wear and corrosion, it can be... By unscrewing the connecting post 401 and the connecting hole 402, the hammer tip 403 can be removed from the hammer body 1. Then, the fastening screw 404 can be unscrewed, and a new hammer tip 403 can be installed to replace it. When not in use, the connecting post 401 of the hammer tip 403 can be screwed into the connecting hole 402. The connecting post 401 pushes the connecting strip 502 to rotate, which causes the three protective plates 503 to move towards the center under the action of the telescopic spring 505. Thus, the hammer tip 403 is retracted into the space between the protective plates 503. The protective plates 503 protect the hammer tip 403 and reduce wear. The hammer body 1 can also be supported by the three support feet 504 to prevent the hammer body 1 from being tilted on the ground or table. The hammer body 1 will not roll, reducing corrosion caused by contact between the hammer body 1 and liquids on the table or ground.
