[0002] Verticality measurement refers to the condition that the measured element on the part maintains the correct 90° angle relative to the reference element. This is also commonly referred to as the degree to which the two elements must be orthogonal. For buildings, during the main construction, the control measurement of the verticality of the building is an important measurement point. It is necessary not only to observe the verticality of each floor and provide the control data to professional quality inspectors so that they can adjust and check the verticality of the building in time. In addition, detailed vertical control lines must be provided to construction personnel. In the construction of building projects, especially in the construction of medium and high-rise buildings, the control of the verticality of the building is an important factor affecting the construction quality;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the examples given are not intended to limit the present utility model.

[0028] Referring to Figure 1 as shown, a verticality measuring device according to the present utility model includes a measuring scale; the measuring scale 1 includes a first measuring scale 11 and a second measuring scale 12, and the first measuring scale 11 and the second measuring scale 12 are connected by a reel 2; by setting the cooperation of the measuring scale and the rotating shaft, the connection is increased, which is convenient for rotation and folding;

[0029] A scale 7 is provided at the bottom of the first measuring ruler 11 and can slide along the first measuring ruler 11. A card slot 11 is provided inside the scale 7, and a positioning component is provided in the card slot 11 for positioning the position of the scale 7 on the first measuring ruler 11. A telescopic ruler 8 is slidably installed inside the scale 7. The telescopic ruler 8 is stretched conveniently through the internal mechanical elasticity to increase the measuring height.

[0030] A winding component is provided on the second measuring ruler 12. The winding component includes a motor 4, a winding wheel 5, and a wire rope 6. The motor 4 is installed on one side of the second measuring ruler 12. The winding wheel 5 is embedded in the inner cavity of the second measuring ruler 12. The rotor shaft of the motor 4 is connected to the winding wheel 5. The wire rope 6 is wound around the surface of the winding wheel 5. A fixed rod 18 is clamped in the inner cavity of the second measuring ruler 1. A slider 19 is slidably inserted through the surface of the fixed rod 18. A wire guiding hole 20 is provided on the surface of the slider 19, and the wire rope 6 passes through the wire guiding hole 20.

[0031] During operation, by setting the first measuring ruler 11, the second measuring ruler 12, and the rotating shaft 2 to cooperate, the connection is increased, facilitating rotation and folding. At the same time, the rotor shaft of the motor 4 can be connected to the center position of one end of the winding wheel 5 through an interference key connection, thereby driving the winding wheel 5 to rotate. Then, by forward and reverse rotation, the vertical bucket 3 is driven to rise or fall. The wire rope 6 is installed and fixed to the vertical bucket 3 through threads, facilitating repeated disassembly and use. During the process of winding and unwinding the wire rope, the wire rope 6 passes through the slider 19, and the slider 19 slides on the surface of the fixed rod 18, increasing the guiding effect and preventing winding at one place, facilitating storage. At the same time, the measuring ruler 1 and the scale 7 facilitate the measurement of bent places such as the corner of a wall. At the same time, the telescopic ruler 8 is stretched conveniently through the internal mechanical elasticity to increase the measuring height. The positioning component plays a role in positioning the position of the sliding scale 7 to prevent tilting.

[0032] Further, a dovetail groove 9 is provided at the bottom of the first measuring ruler 11. A dovetail block 10 is slidably sleeved in the dovetail groove 9. The bottom of the dovetail block 10 is connected to the measuring ruler 1. By setting the dovetail block 10 and the dovetail groove 9 to cooperate, the scale 7 is snapped into the dovetail groove 9 through the dovetail block 10, achieving the effect of guiding installation. Moreover, the interface angle between the scale 7 and the first measuring ruler 11 is a vertical angle, facilitating measurement and also increasing the support height for measurement, facilitating the use of the vertical bucket 3.

[0033] Further, the positioning assembly includes a moving rod 12 and a positioning rod 13 arranged on the moving rod 12. The positioning rod 13 penetrates through the dovetail block 10. The moving rod 12 is slidably sleeved in the card slot 11. A positioning rod 13 is welded to the top of the moving rod 12. The positioning rod 13 penetrates through the dovetail block 10. A plurality of positioning slots 14 for cooperating with the positioning rod 13 are formed in the inner wall of the dovetail groove 9. A tension spring 15 is sleeved on the outer side of the positioning rod 13. The top of the tension spring 15 abuts against the inner wall of the card slot 11, and the bottom of the tension spring 15 abuts against the top of the moving rod 12. During operation, by providing the positioning assembly, the user presses the moving rod 12, and the moving rod 12 drives the positioning rod 13 into the card slot 11, thereby driving the tension spring 15 to deform under force. The scale 7 is inserted into the dovetail groove 9 through the dovetail block 10. After adjusting the position according to requirements, the tension spring 15 resets and drives the positioning rod 13 to pass through the dovetail block 10 and enter the positioning slot 14. The dovetail block 10 prevents the scale 7 from detaching from the bottom of the first measuring ruler 11, and the positioning rod 13 prevents the dovetail block 10 from sliding left and right in the dovetail groove 9, thereby achieving the positioning effect and increasing the supporting force.

[0034] Further, one end of the moving rod 12 extends out of the card slot 11. A clamping block 16 is fixedly screwed to one end of the moving rod 12. A through hole 17 for cooperating with the positioning rod 13 is formed in the top of the dovetail block 10. By providing the clamping block 16, it is convenient for the user to press the moving rod 12 and the positioning rod 13 conveniently from the outside, and the through hole 17 facilitates the up and down movement of the positioning rod 13 to prevent jamming.

[0035] For the perpendicularity measuring device based on the above structure, its working process is as follows: The user presses the clamping block 16, and the clamping block 16 drives the moving rod 12 to move. The moving rod 12 drives the positioning rod 13 into the card slot 11, thereby driving the tension spring 15 to deform under force. The scale 7 is inserted into the dovetail groove 9 through the dovetail block 10. After adjusting the position according to requirements, the tension spring 15 resets and drives the positioning rod 13 to pass through the dovetail block 10 and enter the positioning slot 14. The dovetail block 10 prevents the scale 7 from detaching from the bottom of the measuring ruler 1, and the positioning rod 13 prevents the dovetail block 10 from sliding left and right in the dovetail groove 9, thereby achieving the positioning effect and increasing the supporting force. By the rotation of the motor 4, the wire winding wheel 5 is driven to rotate, thereby driving the vertical bucket 3 to rise or fall through forward and reverse rotation. The wire rope 6 is installed and fixed to the vertical bucket 3 by threads. During the process of taking in and paying out the wire, the wire rope 6 passes through the slider 19, and the slider 19 slides on the surface of the fixed rod 18, increasing the guiding and preventing winding at one place, facilitating repeated disassembly and use, achieving the effect of automatic taking in and paying out the wire and preventing the wire rope 6 from winding.

[0036] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of this utility model.
