Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a construction plumb bob device for preventing knotting. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. "Buildings" specifically refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that meet people's needs for production, residence, study, and public activities. In construction, a plumb line is commonly used to measure the verticality of the building surface; this involves using the weight of a plumb bob to pull a plumb line perpendicular to the ground.

[0003] However, commercially available construction plumb bobs typically have a simple structure, consisting of a single bob device wrapped around the marking line and a pendant. In practical applications, it has been found that because the line needs to be unwound and stored before and after construction, the simple single bob device requires manual winding of the line, which easily leads to tangling and knotting. This renders the entire device unusable and results in significant deviations in measurement results. Therefore, we have proposed an anti-knotting construction plumb bob device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a construction plumb bob device to prevent knotting in building engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, the housing being an arc-shaped hollow structure. A take-up roller is rotatably mounted on the upper part of the housing, and anti-knotting components are distributed on the lower side of the take-up roller. The anti-knotting components include an anti-knotting frame and a fixing rod, both of which are fixedly mounted on the inner side wall of the housing. A marking line is wound on the take-up roller, and the other end of the marking line passes through the anti-knotting frame and the fixing rod in sequence and is connected to a plumb bob. A sleeve plate is fixedly connected to the side of the housing, and a movable insert plate is connected to the other side of the sleeve plate. A bolt is inserted in the middle of the movable insert plate, and one end of the bolt is connected to a pressure plate. A crank handle is fixedly connected to the middle of the side of the take-up roller, and the crank handle is located on the outside of the housing.

[0006] Preferably, several sets of anti-knotting frames are staggered from top to bottom, and the marking lines pass through several sets of anti-knotting frames in an S-shape, so that the marking lines are grouped and stored to form a certain storage space, reducing the possibility of the lines getting tangled.

[0007] Preferably, the marking on the fixing rod is wrapped around the plumb line once to facilitate vertical connection of the plumb line, allowing the plumb line to pass vertically through the opening at the bottom of the housing.

[0008] Preferably, a magnetic plate is fixedly installed near the inside of the housing of the sinker, so that the sinker is magnetically attracted and fixed by the magnetic plate after the line is wound up, preventing the sinker from entering the inside of the housing and reducing the tangling and knotting of the marking line.

[0009] Preferably, the movable insert plate is configured as an L-shaped structure, with its upper end movably inserted into the outer end of the sleeve plate, and a locking bolt that mates with it is threaded into the side of the sleeve plate, which facilitates adjustment and fixation of walls of different thicknesses.

[0010] Preferably, the bolt is threaded onto the movable insert plate, and the side of the pressure plate that is close to the housing is fixedly glued with a rubber anti-slip pad, so that the device generates friction with the measuring wall and reduces shaking.

[0011] Preferably, a locking bolt is threaded into the outer edge of the housing, and the housing has a locking hole that matches it, so that it can be fixed with the locking bolt after being adjusted to the required marking length.

[0012] This utility model provides a construction plumb bob device to prevent knotting, which has the following beneficial effects:

[0013] By incorporating a rotating take-up roller controlled by a crank, the marking line can be laid out and retrieved. Anti-tangling frames are arranged in a staggered pattern from top to bottom, with the marking line passing through several sets of frames in an S-shape, allowing the marking line to move independently and reducing the possibility of tangling. A magnetic plate is fixedly installed at the bottom of the housing, creating a magnetic attraction to the plumb bob and reducing the impact of plumb bob swaying on the internal marking line. An L-shaped movable insert plate is installed, with its upper end movably inserted into the outer end of the sleeve plate, and a locking bolt is threaded into the side of the sleeve plate, allowing for adjustment to different surveying structures. A rubber anti-slip pad is glued to the surface of the pressure plate, working in conjunction with the rubber pad to greatly increase friction with the surveying structure, reducing swaying and improving work efficiency to some extent.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown in the figure, this embodiment proposes a construction plumb bob device for preventing knotting in building engineering, including a housing 1. The housing 1 is configured as an arc-shaped hollow structure. A take-up roller 3 is rotatably installed on the upper part of the interior of the housing 1, and anti-knotting components are distributed on the lower side of the take-up roller 3. The anti-knotting components include an anti-knotting frame 4 and a fixing rod 5, and the anti-knotting frame 4 and the fixing rod 5 are both fixedly installed on the inner side wall of the housing 1. A marking line is wound on the take-up roller 3, and the other end of the marking line passes through the anti-knotting frame 4 and the fixing rod 5 in sequence and is connected to the plumb bob 6. A sleeve plate 8 is fixedly connected to the side of the housing 1, and a movable insert plate 9 is connected to the other side of the sleeve plate 8. A bolt 10 is inserted in the middle position of the movable insert plate 9, and a pressure plate 11 is connected to one end of the bolt 10. A crank handle 13 is fixedly connected to the middle position of the side of the take-up roller 3, and the crank handle 13 is located on the outside of the housing 1.

[0022] The housing 1 has an arc-shaped hollow structure, with one arc-shaped surface conforming to the curvature of the hand for easy handling by workers. The take-up roller 3 has a rotating structure and is internally wound with marking lines. By turning the crank handle 13, the internal marking lines move. The marking lines pass through multiple sets of anti-knotting frames 4, which are staggered from top to bottom. The marking lines pass through in an S-shape and wrap around the fixing rod 5 to connect to the plumb bob 6. The weight of the plumb bob 6 straightens the entire marking line. The front surface of the housing 1 is provided with an observation window 2, which is made of transparent material. The inside of the housing 1 can be observed through the observation window 2 to detect the tangling of the line in time and avoid jamming. A magnetic plate 7 is fixedly installed inside the housing 1. The magnetic plate 7 attracts the plumb bob 6 and fixes it after storage, greatly increasing the practicality of the device.

[0023] A sleeve plate 8 is fixedly connected to the side of the housing 1, and a movable insert plate 9 is connected to the other side of the sleeve plate 8. The movable insert plate 9 is inserted into the inside of the sleeve plate 8, so that the movable insert plate 9 can be adjusted to a suitable position and then fixed by a locking bolt. The movable insert plate 9 is L-shaped, and the middle of the movable insert plate 9 rotates with the thread of the bolt 10, so as to adjust the pressure plate 11, and the building wall to be tested is stuck between the pressure plate 11 and the rubber pad 12. The surface of the pressure plate 11 is glued with a rubber anti-slip pad, which works in conjunction with the rubber pad 12 to increase the friction of the measured building and greatly enhance the stability of the device.

[0024] It should be noted that: first, by adjusting the bolt 10, the internal width of the pressure plate 11 and the rubber pad 12 is adjusted, and the device is fixed to the building wall being measured. Then, the handle 13 is turned to rotate the take-up roller 3, which drives the plumb bob 6 to perform building measurements.
