Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a plumb line device for construction. Background Art

[0002] Construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. During construction, it is necessary to measure the verticality of the building, which requires the use of a plumb line device.

[0003] Patent CN220490062U discloses a plumb line device for construction engineering. The plumb line device controls the drop of the plumb line through a motor, thereby increasing the speed and efficiency of measurement. The device can also switch between electric and manual operation according to actual conditions. However, the plumb line device is not easy to fix during use, and requires manual holding of the plumb line for measurement, resulting in relatively low measurement accuracy. This brings great inconvenience to construction work, and may cause the center of gravity of the cone block to be unstable, which may affect the measurement work of the staff. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a plumb line device for construction, which is provided with a fixing mechanism to facilitate the fixing of the device to the wall and improve the measurement accuracy.

[0005] To achieve this technical purpose, the utility model adopts the following scheme:

[0009] Furthermore, the fixing mechanism also includes a motor, which is arranged inside the second installation box. The output end of the motor is connected to the bidirectional screw. The motor drives the bidirectional screw to rotate, drives the installation part to move and then drives the clamping block to move, thereby realizing the fixation of the construction plumb line device.

[0010] Furthermore, both sides of the mounting member are slidably connected with sliding rods, and both ends of the sliding rods are fixedly connected to the inner wall of the first mounting box.

[0011] Furthermore, an anti-slip buckle is provided on the inner side of the clamping block to increase the clamping and fixing effect on the wall.

[0012] Furthermore, a limiting hole is provided at the bottom of the first installation box, and the limiting hole is slidably connected to the connecting rod.

[0013] Furthermore, a handle is fixedly connected to the top of the first installation box, and a fixing groove is provided on one side of the second installation box.

[0024] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0025] See also Figures 1 to 3 The utility model provides a plumb bob device for construction, comprising a first installation box 1, a handle 6 is fixedly connected to the top of the first installation box 1, a limiting hole 4 is provided at the bottom of the first installation box 1, and a second installation box 2 is arranged on one side of the first installation box 1.

[0026] A fixing mechanism 3 is provided in the first installation box 1, and the fixing mechanism 3 includes a motor 31, a bidirectional screw 32, a mounting piece 33, a sliding rod 34, a connecting rod 35 and a clamping block 36. The bidirectional screw 32 is arranged inside the first installation box 1, and the bidirectional screw 32 is connected to the output end of the motor 31. The motor 31 is arranged inside the second installation box 2, and both ends of the bidirectional screw 32 are respectively threadedly connected with a mounting piece 33, and both sides of the two mounting pieces 33 are slidably connected with sliding rods 34, and both ends of the sliding rod 34 are fixedly connected to the inner wall of the first installation box 1, and a connecting rod 35 is provided at the lower end of the mounting piece 33, and the connecting rod 35 is slidably connected to the limiting hole 4, and a clamping block 36 is provided at the lower end of the connecting rod 35, and anti-slip buckles 37 are provided on the inner sides of the two clamping blocks 36.

[0027] By setting up the fixing mechanism 3, when the construction workers use the plumb line to measure, the clamp block 36 clamps and fixes the wall, and the mounting member 33 moves driven by the bidirectional screw 32 set at the output end of the motor 31, and the connecting rod 35 drives the clamp block 36 to move in opposite directions through the mounting member 33, thereby clamping and fixing the wall. The anti-slip buckle 37 is set on the inner side of the clamp block 36, which can increase the friction between the clamp block 36 and the wall, so that the device can be better fixed on the wall to be tested.

[0028] See also Figure 1 , Figures 4 to 6A wire-releasing hole 5 is provided at the bottom of the second installation box 2, a bearing 8 is provided on the inner wall of the second installation box 2, the bearing 8 is key-connected to the rotating shaft 9, a reel 10 is fixedly connected to the upper part of the rotating shaft 9, a pendant rope 11 is wound around the reel 10, the free end of the pendant rope 11 passes through the wire-releasing hole 5 and is connected to a mounting buckle 12, a rotating block 13 is connected to the bottom of the mounting buckle 12, and a cone block 14 is rotatably connected to the outer side of the rotating block 13. A fixing groove 7 is provided on the side of the second installation box 2 away from the first installation box 1, one end of the rotating shaft 9 extends to the outer side of the first installation box 1 and is fixedly connected to a cross bar 15, a slidingly connected rotating rod 16 is mounted on the cross bar 15, both ends of the rotating rod 16 are fixedly connected to limit blocks 17, and the limit blocks 17 are engaged with the fixing groove 7.

After the construction personnel hold the rotating rod 16 and rotate it, the rotating rod 16 drives the cross bar 15 and the rotating shaft 9 to rotate, thereby causing the reel 10 to retract and release the falling rope 11, so that the cone block 14 at the bottom of the falling rope 11 is vertically lifted and lowered. Under the action of the mounting buckle 12 and the rotating block 13, the rotation of the cone block 14 during placement is avoided to prevent the falling rope 11 from being twisted, so that the cone remains stable and is more convenient to use. When the rotating rod 16 rotates to a certain extent and the falling rope 11 is placed to an appropriate extent, the rotating rod 16 is pushed toward the second installation box 2, so that the limit block 17 is engaged with the fixing groove 7 opened on one side of the second installation box 2, so that the rotating rod 16 is limited and fixed, thereby preventing the reel 10 from rotating to release the line, thereby improving the convenience of use for construction personnel.
