Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figure 1-6 As shown, in this embodiment, a device for measuring the area of ​​a house includes: a plate 1, a laser measuring component 2 and a rope measuring component 3. Both sides of the plate 1 are fixedly connected with a rotating shaft 11, and a frame 12 is provided outside the plate 1. The plate 1 and the frame 12 are rotatably connected via the rotating shaft 11. One end of the plate 1 and the frame 12 are provided with a groove 13. This device can synchronously measure the length and width of a room, can measure the angle of a wall corner, and can measure the area of ​​an irregular shape such as a cylinder.

[0040] During implementation, the plate 1 and the frame 12 are rotated apart via the shaft 11, and the outer sides of the plate 1 and the frame 12 are aligned with the wall. As the shaft 11 rotates, the pointer 14 rotates synchronously, and the angle of the wall corner can be measured by comparing with the scale 15.

[0041] Example 2

[0042] On the basis of the first embodiment, in order to achieve synchronous measurement of the length and width of the room, a laser measurement component 2 is provided.

[0043] like Figure 2 As shown, in this embodiment, the laser measurement assembly 2 includes: a box body 21, a laser rangefinder 22 and a display screen 23. The two box bodies 21 are fixedly connected to the two grooves 13 respectively; the two laser rangefinders 22 are fixedly arranged in the two box bodies 21 respectively; the display screen 23 is fixedly arranged on one side of the board body 1, and the display screen 23 is electrically connected to the two laser rangefinders 22 and can control the laser rangefinders 22.

[0044] During specific implementation, the plate body 1 and the frame body 12 are rotated apart via the rotating shaft 11, and the outer sides of the plate body 1 and the frame body 12 are aligned with the wall so that the length and width of the frame body 12 and the plate body 1 are parallel respectively. The two laser rangefinders 22 are started to measure the length and width, and the size is displayed on the display screen 23.

[0045] Example 3

[0046] On the basis of the first embodiment, in order to realize the measurement of the cylinder, a rope measurement component 3 is provided.

[0047] like Figure 4-6As shown, in this embodiment, the rope measuring assembly 3 includes: a housing 31, a hydraulic rod 32, a clamping joint 33, a motor 34, a connecting block 35 and a clamping rod 36. The housing 31 is fixedly connected to one side of the plate body 1, and the housing 31 is provided with an opening; the hydraulic rod 32 is fixedly connected to the inner top of the housing 31, and the driving end of the hydraulic rod 32 is rotatably connected to the winding roller 321, and the measuring rope 322 is wound around the winding roller 321; the clamping joint 33 is fixedly connected to the bottom end of the winding roller 321; the motor 34 is fixedly connected to the inner bottom of the housing 31, and the driving end of the motor 34 is fixedly connected to the clamping ring 341; the connecting block 35 is fixedly connected to the clamping ring 341; the clamping rod 36 The bottom end of the clamping rod 36 is rotatably connected to one end of the connecting block 35, and is rotatably connected to two rotating wheels 361; a guide roller 38 is rotatably connected inside the shell 31, and the measuring rope 322 extends out of the opening of the shell 31 through the guide roller 38; after the measurement, the hydraulic rod 32 is started, and the hydraulic rod 32 drives the winding roller 321 to descend, thereby driving the clamping joint 33 to be clamped into the clamping ring 341. During this process, the clamping joint 33 descends and extends into the clamping ring 341, and will first touch multiple sets of rotating wheels 361, thereby driving the clamping rod 36 to rotate. The rotation of multiple sets of clamping rods 36 will clamp and be clamped in the groove 13 of the clamping joint 33, thereby fixing the clamping joint 33, that is, fixing the winding roller 321.

[0048] Furthermore, a connecting seat 37 is fixedly connected inside the shell 31, and one end of the connecting seat 37 is fixedly connected to a limiting ring 371. The limiting ring 371 is limitedly sleeved outside the winding roller 321. By setting the limiting ring 371, the lifting and lowering of the winding roller 321 can be limited to avoid deviation. At the same time, the setting of the limiting ring 371 does not affect the pulling out of the measuring rope 322.

[0049] In specific implementation, when it is necessary to measure the area of ​​an irregular shape such as a cylinder, the measuring rope 322 is pulled, and the measuring rope 322 drives the winding roller 321 to rotate. The shell 31 is pulled out through the guidance of the guide roller 38, and the circumference of the cylinder is measured, and the radius of the cylinder is calculated based on the circumference.

[0050] Working principle: First, rotate the plate body 1 and the frame body 12 through the rotating shaft 11, align the outer sides of the plate body 1 and the frame body 12 with the wall, so that the frame body 12 and the plate body 1 are parallel to the length and width respectively. In this process, the pointer 14 is rotated synchronously due to the rotation of the rotating shaft 11. By comparing with the scale 15, the angle of the wall corner can be measured. Then, start the two laser rangefinders 22 to measure its length and width, and display the size on the display screen 23. When it is necessary to measure the area of ​​a special shape such as a cylinder, pull the measuring rope 322, and the measuring rope 322 drives the winding roller 321 to rotate. Through the guidance of the guide roller 38, pull out the shell 31, measure the circumference of the cylinder, and calculate the radius of the cylinder through the circumference. After the measurement, start the liquid The pressure rod 32 and the hydraulic rod 32 drive the winding roller 321 to descend, thereby driving the clamping joint 33 to be clamped into the clamping ring 341. During this process, the clamping joint 33 descends and extends into the clamping ring 341, and first touches the multiple sets of rotating wheels 361, thereby driving the clamping rod 36 to rotate. The rotation of the multiple sets of clamping rods 36 will clamp and clamp in the groove 13 of the clamping joint 33, fixing the clamping joint 33, that is, fixing the winding roller 321, and vice versa, the clamping joint 33 rises and can be separated from the clamping of the clamping ring 341 and the clamping rod 36. Since the top of the winding roller 321 is rotatably connected to the driving end of the hydraulic rod 32, after the measurement is completed, the hydraulic rod 32 and the motor 34 are started in sequence to drive the measuring rope 322 to be reeled.
