DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A plumb bob for measuring a construction project comprises a plumb bob 1, a winding roller 12 is rotatably provided in the plumb bob 1, an opening 3 is provided on the outer wall of the plumb bob 1, a movable groove 13 is provided on the inner wall of the opening 3, a reciprocating screw 18 is rotatably provided in the movable groove 13, a transmission chamber 15 is provided in the wall of the plumb bob 1, the ends of the winding roller 12 and the reciprocating screw 18 both extend into the transmission chamber 15 and are connected through a transmission mechanism, a movable rod 14 is provided on the reciprocating screw 18 through a threaded sleeve of a limiting mechanism, a wire drawing ring 4 is provided on the movable rod 14, two mounting rods 5 are installed on the plumb bob 1, one of the mounting rods 5 is fixedly connected to the plumb bob 1, and a connecting block 10 is provided on the other mounting rod 5, a connecting groove 9 is provided on the outer wall of the plumb bob 1, the connecting block 10 is connected to the connecting groove 9 through an elastic mechanism, a wiping ring 6 is provided between the two mounting rods 5 through an insertion mechanism, and a wiping cloth 7 is provided in the wiping ring 6.

[0023] The transmission mechanism includes a pulley 16 arranged on the winding roller 12 and the reciprocating screw 18. The two pulleys 16 are connected by a belt 17. The pulley 16 and the belt 17 are used to achieve synchronous rotation of the winding roller 12 and the reciprocating screw 18.

[0024] The limiting mechanism includes a limiting rod 19 arranged in the movable groove 13 . The limiting rod 19 slides through the movable rod 14 . The limiting rod 19 limits the movable rod 14 , thereby preventing the movable rod 14 from rotating together with the reciprocating screw 18 .

[0025] The elastic mechanism includes a spring 11 arranged in the connecting groove 9, and the two ends of the spring 11 are elastically connected to the outer wall of the connecting block 10 and the inner wall of the connecting groove 9 respectively. The spring 11 realizes the dragging of the connecting block 10 to make it close to the wiping ring 6, and the two mounting rods 5 realize the clamping and fixing of the wiping ring 6.

[0026] The plug-in mechanism includes an insert block 8 arranged on the mounting rod 5 . The outer wall of the wiping ring 6 is provided with a slot corresponding to the insert block 8 . The insert block 8 is inserted into the slot to achieve stable connection of the wiping ring 6 relative to the mounting rod 5 .

[0027] The inner wall of the wire drawing ring 4 is polished to ensure smoothness when the polishing wire passes through. The wiping cloth 7 is installed on the arc-shaped inner wall of the wiping ring 6 by Velcro. The installation is convenient and the wiping cloth 7 can be disassembled and replaced.

[0028] When the utility model is used, the wire body is wound on the winding roller 12, and the winding roller 12 can be rotated by means of the rotating frame 2 to realize the winding operation, wherein the line release can be naturally realized by relying on the gravity of the lead sinker.

[0029] When the winding roller 12 rotates, the reciprocating screw 18 can be driven to rotate with the help of the pulley 16 and the belt 17. When the reciprocating screw 18 rotates, the movable rod 14 on it drives the wire winding ring 4 to move, thereby realizing the wire winding operation and ensuring that the wire body can be wound in circles.

[0030] Among them, the wire body also passes through the wiping ring 6, and can be wiped and cleaned by the wiping cloth 7 through the wiping ring 6 to ensure cleanliness. One of the mounting rods 5 can be dragged away from the other mounting rod 5. When the two mounting rods 5 are away from each other, the clamping of the wiping ring 6 is released, and the wiping ring 6 is disassembled. After disassembly, it is easier to clean or replace the wiping cloth 7.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
