Description

Technical Field

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

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "worksite." Using a plumb line is a commonly used measurement method in construction, primarily used to ensure the accuracy of the building's verticality and horizontality.

[0003] A search revealed Chinese patent application number 202220320813.9, which discloses a plumb bob device for construction, relating to the field of plumb bob measurement. The arrangement component includes a second fixing rod. A reciprocating threaded rod is fixedly connected to the upper surface of the base via two symmetrically arranged second fixing rods. A toothed pulley is slidably connected to the upper surface of the base. The reciprocating threaded rod passes through the pulley and is threadedly connected to it. The toothed pulley meshes with the plumb bob. This utility model provides an arrangement component that allows the plumb bob to be evenly distributed on the surface of the first take-up drum, further avoiding the problem of tangling.

[0004] Although the arrangement component provided by the aforementioned patent has the advantage of allowing the sinker to be evenly laid on the surface of the first take-up drum, further avoiding the problem of tangling, it is not convenient to fix the device in actual use. During measurement, the device is prone to displacement, resulting in inaccurate measurement results. At the same time, it is not convenient to adjust the falling position of the sinker as needed, which brings inconvenience to the user.

[0005] Therefore, it needs to be modified to allow the device to be easily fixed to the building wall, effectively preventing displacement during use, improving measurement accuracy, and making it convenient for users to adjust the falling position of the plumb bob as needed. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a plumb bob device for construction, which has the advantages of being easy to fix to the building wall, effectively preventing displacement of the device during use, improving measurement accuracy, and facilitating adjustment of the plumb bob's falling position as needed, thus making it convenient for users. This solves the problems of inconvenience in fixing the device, easy displacement of the device during measurement leading to inaccurate results, and difficulty in adjusting the plumb bob's falling position as needed, which cause inconvenience to users.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a plumb bob device for construction, comprising a support plate, a first side plate fixedly connected to the left side of the bottom of the support plate, a second side plate fixedly connected to the right side of the bottom of the support plate, a clamping plate slidably connected to the bottom of the support plate between the first and second side plates, a screw block fixedly connected to the center of the first side plate, a screw rod threadedly connected to the inside of the screw block, the right end of the screw rod rotatably connected to the left side of the clamping plate, a rotating plate rotatably connected to the top of the support plate, and a threaded hole formed on the left side of the rotating plate. The rotating plate is threaded with positioning bolts. Slide rails are fixedly connected to the front and rear sides of the top of the rotating plate. A movable platform is slidably connected to the surface of the slide rails. A wire box is fixedly connected to the top of the movable platform. A wire roller is rotatably connected to the front side of the inner wall of the wire box. A weight assembly is wound around the surface of the wire roller. The head end of the weight assembly is fixedly connected to the surface of the wire roller. The rear end of the wire roller extends through to the back of the wire box and is fixedly connected to a rotating wheel. The left side of the movable platform has through-holes on both the front and rear sides. A positioning mechanism is installed inside the holes. A number of evenly distributed locking holes are opened on the top of the slide rails.

[0008] In a preferred embodiment of this utility model, the positioning mechanism includes a locking rod that is slidably connected inside the circular hole and used in conjunction with the locking hole. A pull rod is fixedly connected to the top of the locking rod, and a tension spring is sleeved on the surface of the locking rod. The top of the tension spring is fixedly connected to the bottom of the pull rod, and the bottom of the tension spring is fixedly connected to the top of the moving platform.

[0009] As a preferred embodiment of the present invention, the first side plate has through holes on both the front and rear sides, and a stabilizing rod is slidably connected inside the holes, with the right end of the stabilizing rod being fixedly connected to the left side of the clamping plate.

[0010] As a preferred embodiment of this utility model, a magnetic ring is fixedly connected to the back of the wire box, a through hole is opened on the surface of the rotating wheel, and a handle is slidably connected inside the through hole. A magnetic block is fixedly connected to the front end of the handle, and the surface of the magnetic block is magnetically connected to the surface of the magnetic ring.

[0011] In a preferred embodiment of this invention, the top of the bearing plate is fixedly connected to an annular rail, and the bottom of the rotating plate is fixedly connected to a slip ring, the surface of which is slidably connected to the inner wall of the annular rail.

[0012] As a preferred embodiment of this utility model, an anti-slip pad is fixedly connected to the left side of the second side plate, and a buffer pad is fixedly connected to the right side of the clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves placing the device above the wall to be measured, with the bottom of the bearing plate in contact with the top of the wall and the second side plate in contact with the right side of the wall. Then, rotating the screw moves the clamping plate to the right, bringing the right side of the clamping plate into contact with the left side of the wall, thus clamping and fixing the device above the wall. Loosening the positioning bolts moves the bottom away from the bearing plate, allowing the rotating plate to rotate. Depending on the measurement requirements, the slide rail is aligned with the target point. The positioning bolts are then tightened so that the bottom of the rotating plate contacts the top of the bearing plate, fixing the rotating plate in place. Next, the positioning mechanism is pulled upwards and the moving platform is pushed outwards to the desired measurement point. The positioning mechanism is then released to reset and fix the moving platform. Finally, the plumb bob is released by rotating the rotating wheel for measurement. This method allows for convenient fixing of the device to the building wall, effectively preventing displacement during use, improving measurement accuracy, and facilitating adjustment of the plumb bob's falling position as needed, thus providing convenience for the user.

[0015] 2. This utility model uses a combination of a locking rod, a pull rod, and a tension spring. The tension of the tension spring causes the pull rod to move the locking rod downwards, so that the bottom of the locking rod fits against the inner wall of the locking hole, thus fixing the moving platform. Conversely, pulling the pull rod upwards causes the locking rod to move away from the locking hole, thus releasing the fixing of the moving platform and facilitating the adjustment of the moving platform's position.

[0021] 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.

[0022] like Figures 1 to 4 As shown, this utility model provides a plumb bob device for construction, including a support plate 1, a first side plate 2 fixedly connected to the left side of the bottom of the support plate 1, a second side plate 3 fixedly connected to the right side of the bottom of the support plate 1, a clamping plate 4 slidably connected to the bottom of the support plate 1 between the first side plate 2 and the second side plate 3, a screw block 5 fixedly connected to the center of the first side plate 2, a screw rod 6 threadedly connected to the inside of the screw block 5, the right end of the screw rod 6 rotatably connected to the left side of the clamping plate 4, a rotating plate 7 rotatably connected to the top of the support plate 1, a threaded hole on the left side of the rotating plate 7, and a positioning bolt 8 threadedly connected to the inside of the threaded hole. The top of the rotating plate 7 is fixedly connected to the front and rear sides of the slide rail 9. The surface of the slide rail 9 is slidably connected to the moving platform 10. The top of the moving platform 10 is fixedly connected to the wire box 11. The front side of the inner wall of the wire box 11 is rotatably connected to the wire roller 12. The surface of the wire roller 12 is wound with a weight assembly 13. The head end of the weight assembly 13 is fixedly connected to the surface of the wire roller 12. The rear end of the wire roller 12 passes through to the back of the wire box 11 and is fixedly connected to the rotating wheel 14. The left side of the moving platform 10 has a through-hole on both the front and rear sides. The inside of the hole is a positioning mechanism 15. The top of the slide rail 9 has a number of evenly distributed locking holes 16.

[0023] refer to Figure 1 The positioning mechanism 15 includes a locking rod 17 that is slidably connected inside the circular hole and used in conjunction with the locking hole 16. A pull rod 18 is fixedly connected to the top of the locking rod 17. A tension spring 19 is sleeved on the surface of the locking rod 17. The top of the tension spring 19 is fixedly connected to the bottom of the pull rod 18, and the bottom of the tension spring 19 is fixedly connected to the top of the moving platform 10.

[0024] As a technical optimization of this utility model, by setting up the cooperation of the locking rod 17, the pull rod 18 and the tension spring 19, the tension spring 19 causes the pull rod 18 to drive the locking rod 17 downward, so that the bottom of the locking rod 17 fits against the inner wall of the locking hole 16, which can fix the moving platform 10. Conversely, pulling the pull rod 18 upward to move the locking rod 17 away from the locking hole 16 can release the fixation of the moving platform 10, which facilitates the position adjustment of the moving platform 10.

[0025] refer to Figure 1 The first side plate 2 has through holes on both the front and back sides, and a stabilizing rod 20 is slidably connected inside the holes. The right end of the stabilizing rod 20 is fixedly connected to the left side of the clamping plate 4.

[0026] As a technical optimization of this utility model, by setting a stabilizing rod 20, when the screw 6 rotates and drives the clamping plate 4 to move, the stabilizing rod 20 moves inside the slot, which plays a supporting and reinforcing role on the left and right sides of the clamping plate 4, and avoids the clamping plate 4 from shaking or tilting during the movement, which would affect normal use.

[0027] refer to Figure 3 A magnetic ring 21 is fixedly connected to the back of the wire box 11. A through hole is opened on the surface of the rotating wheel 14, and a handle 22 is slidably connected inside the through hole. A magnetic block 23 is fixedly connected to the front end of the handle 22. The surface of the magnetic block 23 is magnetically connected to the surface of the magnetic ring 21. The magnetic force generated by the magnetic block 23 and the magnetic ring 21 is greater than the weight of the plumb bob assembly 13.

[0028] As a technical optimization of this utility model, the combination of magnetic ring 21, grip 22 and magnetic block 23 fixes the rotating wheel 14 and the wire roller 12. When the line needs to be fixed after the line is unloaded, the rotating wheel 14 is positioned by the magnetic connection between the magnetic block 23 and the magnetic ring 21, thus fixing the wire roller 12. When the line needs to be unloaded or reloaded, the grip 22 can be pulled back to move the magnetic block 23 away from the magnetic ring 21, thereby rotating the rotating wheel 14 to drive the wire roller 12 to unload or reload the line, which is convenient for the user.

[0029] refer to Figure 3 The top of the bearing plate 1 is fixedly connected to an annular rail 24, and the bottom of the rotating plate 7 is fixedly connected to a slip ring 25. The surface of the slip ring 25 is slidably connected to the inner wall of the annular rail 24.

[0030] As a technical optimization of this utility model, the use of the annular rail 24 and the slip ring 25 together provides support and reinforcement for the rotating plate 7. At the same time, it makes the rotating plate 7 more stable when it is rotated and adjusted, and avoids the rotating plate 7 from shaking during rotation, which would affect its use.

[0031] refer to Figure 1The left side of the second side plate 3 is fixedly connected to an anti-slip pad 26, and the right side of the clamping plate 4 is fixedly connected to a buffer pad 27.

[0032] As a technical optimization of this utility model, by setting the anti-slip pad 26 and the buffer pad 27 together, the friction between the second side plate 3 and the wall is increased, avoiding slippage and tilting. By setting the buffer pad 27, the pressure on the clamping plate 4 when it is fixed to the wall is reduced, avoiding damage and deformation of the clamping plate 4.

[0033] The working principle and usage process of this utility model are as follows: The device is placed above the wall to be measured, with the bottom of the bearing plate 1 in contact with the top of the wall and the second side plate 3 in contact with the right side of the wall. Then, the screw 6 is rotated to move the clamping plate 4 to the right, so that the right side of the clamping plate 4 contacts the left side of the wall, clamping and fixing the device above the wall. The positioning bolt 8 is loosened to move its bottom away from the bearing plate 1. At this point, the rotating plate 7 can be rotated. According to the measurement requirements, the slide rail 9 is aligned with the target point for the line. Then, the positioning bolt 8 is tightened so that its bottom contactes the top of the bearing plate 1, fixing the rotating plate 7. Next, the positioning mechanism 15 is pulled upwards and the moving platform 10 is pushed outwards, pushing the moving platform 10 above the required measurement point. The positioning mechanism 15 is released to reset the moving platform 10, fixing it in place. Then, the plumb bob group 13 is released by rotating the rotating wheel 14 for measurement. This achieves the effect of conveniently fixing the device to the building wall, effectively preventing displacement during use, improving measurement accuracy, and facilitating adjustment of the plumb bob's falling position as needed, making it convenient for the user.
