[0003] Currently, common indoor decoration horizontal measuring devices on the market mainly include bubble levels, laser levels, etc. The bubble level judges whether the measured surface is horizontal by observing the position of the bubble in the glass tube. However, its measurement accuracy is easily affected by manual operation and measurement environment, and when adjusting the level, the operator needs to repeatedly adjust the position of the measuring device, which is a cumbersome and time-consuming process.

The upper end of the base is fixedly connected with a mounting seat. The upper end of the mounting seat is fixedly connected with a frame. A control panel is installed at the upper end of the frame. The upper end of the control panel passes through the housing wall and extends upward, and a control button is installed. There are two connecting rods in the frame. A laser emitter is connected to the frame through the two connecting rods. A laser emission port is opened on the housing wall corresponding to the position of the laser emitter. A swing arm is installed at the center of the bottom of the laser emitter. A counterweight block is fixedly connected to the end of the swing arm away from the laser emitter.

Detailed implementation manners

[0022] Embodiment 1: As Figure 1-9 shown, a horizontal measurement device for indoor decoration includes a horizontal measurement host 1. An annular shell 2 is fixedly installed inside the horizontal measurement host 1. The inner wall of the annular shell 2 is arc-shaped and sleeved with a spherical shell 3. A lubrication assembly 4 is arranged in the inner cavity of the annular shell 2. A first rack 5 is movably installed inside the spherical shell 3. The first rack 5 is vertically arranged. The upper and lower ends of the first rack 5 are respectively fixedly connected with a plurality of second racks 6 in sequence. An automatic adjustment assembly 7 is fixedly installed inside the spherical shell 3. The automatic adjustment assembly 7 is meshed with the first rack 5. The automatic adjustment assembly 7 works to drive the spherical shell 3 to move up and down along the first rack 5 and the second rack 6, so as to adjust the height position of the horizontal measurement host 1. A support plate 8 is installed on the lowermost second rack 6, and a stable installation assembly 9 is arranged on the support plate 8.

[0023] In this embodiment, the horizontal measurement host 1 includes a housing 26. The cross-section of the housing 26 is square on the outside and circular on the inside. A control panel 28, a buzzer 29, a battery 38, and a plurality of laser devices 27 are fixedly installed on the side wall of the housing 26. The plurality of laser devices 27 are respectively installed on the side and bottom surfaces of the horizontal measurement host 1.

[0024] A spirit level 30 is installed on the top surface of the housing 26. By observing the spirit level 30, it can be determined whether the horizontal measurement host 1 is level.

[0025] A plurality of counterweight blocks 31 are fixedly installed on the inner wall of the housing 26. The plurality of counterweight blocks 31 are arranged at intervals. The counterweight blocks 31 are used for counterweight, so that the center of gravity of the horizontal measurement host 1 is located at the center point of the horizontal measurement host 1.

[0026] In this embodiment, the signal output end of the control panel 28 is electrically connected to the laser device 27 and the buzzer 29. The control panel 28 outputs a control signal to control the laser device 27 and the buzzer 29 to work. The battery 38 is used to supply power to the control panel 28, the laser device 27, and the buzzer 29.

[0027] With such a design, the laser devices 27 on the side and bottom surfaces of the horizontal measurement host 1 are started through the control panel 28, so that the laser devices 27 emit light beams in a specified direction. The operator can perform horizontal measurement operations at a specified height and direction by finely adjusting the direction of the horizontal measurement host 1. The operator can also observe the level situation through the spirit level 30. And if the situation of being unable to be level occurs, the operator can perform fine adjustment operations according to the actual situation, so that the horizontal measurement host 1 can be in a horizontal position.

[0028] In this embodiment, the laser device 27 is a prior art and can be directly purchased on the market. The laser device 27 is used to emit light beams in a specified direction to realize horizontal measurement operations at a specified height and direction.

[0029] As Figure 3 shown, the lubrication assembly 4 includes an annular plate 10. An annular cavity is formed inside the annular shell 2. The annular plate 10 is movably installed in the annular cavity, and the inner and outer diameters of the annular shell 2 match the inner and outer diameters of the annular cavity. Sealing rings 11 are fixedly connected to the inner and outer side walls of the annular plate 10. The sealing rings 11 are slidably and sealingly connected to the inner surface of the annular cavity.

[0030] A plurality of automatic telescopic rods 12 are fixedly installed on the bottom surface of the annular shell 2. The plurality of automatic telescopic rods 12 are annular and arranged at intervals. The telescopic ends of the automatic telescopic rods 12 penetrate through the lower surface of the annular shell 2 and are fixedly connected to the annular plate 10.

[0031] A plurality of through holes 13 are evenly distributed on the inner side wall of the annular shell 2, and a feed pipe 14 is fixedly connected to the top surface of the annular shell 2. The through holes 13 and the feed pipe 14 are both communicated with the annular cavity.

[0032] With such a design, during the use process, the automatic telescopic rod 12 pushes the annular plate 10 to move inside the annular shell 2, discharging the lubricating oil inside the annular shell 2 from the through holes 13. The lubricating oil will cover the outer wall of the spherical shell 3, realizing the lubrication between the annular shell 2 and the spherical shell 3. At this time, under the action of the gravity of the horizontal measuring host 1, the annular shell 2 can move on the outer wall of the spherical shell 3, enabling the horizontal measuring host 1 to be automatically adjusted to a horizontal state, realizing a convenient leveling operation for the measuring device and facilitating use.

[0033] In this embodiment, the automatic telescopic rod 12 is one of an electric telescopic rod, a hydraulic cylinder, and a pneumatic telescopic rod.

[0034] In this embodiment, a plugging cover is detachably installed on the feed pipe 14. The plugging cover is used to open or close the feed pipe 14, and the feed pipe 14 is used to inject lubricating oil into the annular cavity.

[0035] As Figure 2 and Figure 5 shown, the automatic adjustment component 7 includes a motor 15. A rotating shaft 16 is fixedly connected to the power output end of the motor 15, and a first gear 36 is fixedly connected to the rotating shaft 16. The first gear 36 is meshed and connected with a first rack 5.

[0036] Two side plates 17 are movably installed on the rotating shaft 16. The two side plates 17 are respectively fixedly connected to the inner wall of the spherical shell 3. The two side plates 17 are used to stably place the rotating shaft 16 and support the rotation of the rotating shaft 16.

[0037] With such a design, when a horizontal measurement operation needs to be performed during the interior decoration process, the motor 15 is started. The motor 15 outputs rotational power to drive the rotating shaft 16 to drive the first gear 36 to rotate. The first gear 36 is meshed and connected with the first rack 5 and the second rack 6, and is used to drive the horizontal measuring host 1 to move to a specified height, realizing the positioning operation of the measurement height and facilitating the horizontal measurement operation at the specified height.

[0038] In this embodiment, the motor 15 is a prior art and can be a motor with a self-locking brake function. When the motor 15 stops working, the power output end of the motor 15 is self-locked, making the motor 15 unable to rotate after shutdown, thereby realizing the positioning operation of the height position of the horizontal measuring host 1 and preventing the risk that after the motor 15 stops, the power output end of the motor 15 rotates freely and the horizontal measuring host 1 moves downward along the first rack 5 and the second rack 6.

[0039] As Figure 2 and Figure 5 shown, assembly holes 32 are provided at both the upper and lower ends of the first rack 5. The same assembly holes 32 are provided at one end of the second rack 6 away from the first rack 5. Assembly rods 33 are fixedly installed at the other end of the second rack 6 and at the center of the top surface of the support plate 8. The adjacent assembly rods 33 and assembly holes 32 are detachably spliced, and positioning bolts 34 are threadedly connected to the outer side surfaces of the first rack 5 and the second rack 6 near the assembly holes 32.

[0040] With such a design, according to the need for horizontal measurement height in interior decoration, a specified number of second racks 6 are selected. Through the splicing between the assembly holes 32 and the assembly rods 33, the second rack 6 is connected and installed with the first rack 5 and between the second racks 6, and it is ensured that the tooth parts of all the second racks 6 are butted with the first rack 5. Then, the positioning bolts 34 are rotated to complete the positioning and locking between the first rack 5 and the second rack 6 and between the second racks 6, so that the measuring device has a suitable height and is convenient for horizontal measurement at different heights.

[0041] In this embodiment, internal threads are provided on the inner surface of the assembly hole 32, external threads are provided on the outer surface of the assembly rod 33, and the assembly rod 33 and the assembly hole 32 are detachably spliced by threads. And through the abutting of the positioning bolt 34 against the assembly rod 33, the positioning connection between the assembly rod 33 and the assembly hole 32 is realized.

[0042] In addition to this embodiment, the assembly hole 32 is a square blind hole, the assembly rod 33 is a square rod, the assembly rod 33 is detachably inserted into the assembly hole 32, positioning grooves are provided at positions on the outer surface of the assembly rod 33 corresponding to the positioning bolts 34. After the assembly rod 33 is inserted into the assembly hole 32, the positioning bolts 34 are rotated so that the ends of the positioning bolts 34 are inserted into the positioning grooves, thereby realizing the positioning connection between the assembly rod 33 and the assembly hole 32.

[0043] As Figure 2 and Figure 4 shown, the stable installation assembly 9 includes an installation groove. An installation groove penetrating its outer circumferential surface is provided on the support plate 8. The installation groove is opened along the diameter of the support plate 8. Two third racks 18 are slidably installed in the installation groove. The same second gear 19 meshes between the third racks 18. A vertical shaft 20 is coaxially and movably connected to the second gear 19. The lower end of the vertical shaft 20 is fixedly connected to the inner bottom surface of the installation groove.

[0044] One end of each of the two third racks 18 away from each other extends out of the outside of the installation groove and is fixedly connected to an installation plate 21.

[0045] With such a design, by pulling the mounting plates 21 on both sides of the support plate 8, the mounting plates 21 drive the third rack 18 to engage with the second gear 19 and rotate, adjusting the mounting plates 21 on both sides to a certain distance from the support plate 8. Thus, the supporting effect on the measuring device can be effectively improved, making the measuring device have high stability during use and enhancing the use effect.

[0046] In this embodiment, a slide rail and slider assembly (not shown in the figure) may be provided between the inner surface of the mounting groove and the third rack 18. The third rack 18 is slidably mounted on the inner surface of the mounting groove through the slide rail and slider assembly. The overall structure of the slide rail and slider assembly includes a slide rail and a plurality of sliders. The slide rail is fixedly mounted on the inner surface of the mounting groove. The plurality of sliders are arranged at intervals and are respectively fixedly connected to the third rack 18. All the plurality of sliders are slidably connected to the slide rail.

[0047] As Figure 2 and Figure 4 shown, the support plate 8 is circularly arranged and a plurality of mounting holes 35 are formed on its upper surface. Mounting holes 35 are also formed on the mounting plates 21.

[0048] Through the arrangement of the mounting holes 35, bolt fasteners can be inserted into the mounting holes 35, thereby realizing the fixing operation of the measuring device, effectively improving the stability of the measuring device during use, and enhancing the use effect.

[0049] As Figure 4 shown, two fixing plates 22 are symmetrically and fixedly connected to the inner wall of the mounting groove. An activity rod 23 is movably connected to the fixing plates 22. Blocks 24 are fixedly connected to one ends of the activity rods 23 close to the second gear 19. The blocks 24 are engaged with the tooth grooves on the second gear 19.

[0050] Circular plates 25 are fixedly connected to the other ends of the activity rods 23 away from the second gear 19. A spring 37 is sleeved on the activity rods 23. The spring 37 is arranged between the circular plates 25 and the fixing plates 22, and both ends of the spring 37 are fixedly connected to the circular plates 25 and the fixing plates 22 respectively.

[0051] With such a design, after the mounting plates 21 on both sides are pulled out, under the elastic force of the spring 37, the blocks 24 can be engaged with the tooth grooves on the second gear 19, thereby realizing the positioning of the second gear 19, avoiding the instability of the measuring device during use, and enhancing the use effect.

[0052] In this embodiment, to prevent the fixing plates 22 from affecting the sliding of the third rack 18, the upper and lower side surfaces of the fixing plates 22 are respectively fixedly connected to the upper and lower inner surfaces of the mounting groove, and the width of the fixing plates 22 is less than the distance between the two third racks 18.

[0053] In this embodiment, in order to facilitate pulling the circular plate 25, pulling ropes 44 are fixedly connected to the mutually remote sides of the two circular plates 25 respectively, and the other ends of the pulling ropes 44 are fixedly installed on the outer surface of the support plate 8.

[0054] With such a design, by pulling the pulling rope 44, the circular plate 25 and the movable rod 23 can be pulled, so that the movable rod 23 drives the clamping block 24 to move, and the clamping connection between the clamping block 24 and the tooth groove on the second gear 19 is released.

[0055] The present invention also provides a usage method of a horizontal measurement device for interior decoration. Based on the above horizontal measurement device for interior decoration, the usage method includes the following steps: S1: Select a specified number of second racks 6 according to the height requirement of the horizontal measurement for interior decoration. Through the splicing between the splicing holes 32 and the splicing rods 33, connect and install the second racks 6 between the first rack 5 and between the second racks 6, and ensure that the tooth parts of all the second racks 6 are butted with the first rack 5. Then rotate the positioning bolts 34 to complete the positioning and locking between the first rack 5 and the second racks 6 and between the second racks 6, so that the measurement device has a suitable height.

[0056] S2: Splice the splicing rod 33 on the support plate 8 with the splicing hole 32 on the lowermost second rack 6, and perform a pulling operation on the mounting plates 21 on both sides of the support plate 8, so that the mounting plates 21 drive the third rack 18 to engage and rotate the second gear 19, adjust the mounting plates 21 on both sides to a certain distance from the support plate 8, and stop pulling the mounting plates 21. At this time, under the action of the spring 37, the movable rod 23 drives the clamping block 24 to snap into the tooth groove of the second gear 19 to position the second gear 19, so that the mounting plates 21 stably support the measurement device, and fix it through the mounting holes 35 on the support plate 8 and the mounting plates 21 by using bolt fasteners to improve the stability during installation.

[0057] S3: When performing the horizontal measurement operation, start the automatic adjustment component 7 to drive the horizontal measurement main body 1 to move up and down to adjust and position the measurement height.

[0058] In step S3, the working process of the automatic adjustment component 7 is as follows: The motor 15 starts to drive the rotating shaft 16 and the first gear 36 to rotate. The first gear 36 is meshed and connected with the first rack 5 and the second rack 6. During the rotation of the first gear 36, the spherical shell 3 and the horizontal measurement main body 1 can be driven to move up and down, so as to adjust and position the height position of the horizontal measurement main body 1.

[0059] S4: Start the automatic telescopic rod 12, which pushes the annular plate 10 to move in the annular shell 2, and discharges the lubricating oil in the annular shell 2 from the through hole 13. The lubricating oil will cover the outer wall of the spherical shell 3, thereby lubricating the annular shell 2 and the spherical shell 3. At this time, under the action of the gravity of the horizontal measurement host 1, the annular shell 2 moves on the outer wall of the spherical shell 3, thereby adjusting the horizontality of the horizontal measurement host 1. The operator can also fine-tune the position of the horizontal measurement host 1 by observing the level bubble 30.

[0060] S5: After the fine adjustment is completed, the control panel 28 starts the laser device 27 on the side and bottom of the level measurement host 1, so that the laser device 27 emits a light beam in a specified direction. The operator can perform level measurement operations at a specified height and direction by fine-tuning the direction of the level measurement host 1.

[0061] Example 2: Figure 10 As shown, in this embodiment 2, the first rack 5 and the second rack 6 can also be replaced by threaded rods 39; and two adjacent threaded rods 39 are spliced ​​with the assembling rods 33 through the assembling holes 32.

[0062] The difference is that a mounting baffle 43 is fixedly installed at the middle position of the ball shell 3, and the automatic adjustment component 7 is arranged on the mounting baffle 43. The automatic adjustment component 7 includes a threaded sleeve 42, which is rotatably installed on the mounting baffle 43, and the threaded sleeve 42 is sleeved on the threaded rod 39, and the threaded sleeve 42 and the threaded rod 39 are threadedly connected.

[0063] The motor 15 is fixedly mounted on the mounting partition 43 , a worm 41 is drivingly connected to the power output end of the motor 15 , a worm wheel 40 is fixedly mounted on the outer surface of the threaded sleeve 42 , and the worm 41 is meshingly connected to the worm wheel 40 .

[0064] Designed in this way, the motor 15 is used to output rotational power to drive the worm 41 to rotate. The worm 41 is meshed with the worm wheel 40. The rotation of the worm 41 drives the threaded sleeve 42 to rotate through the worm wheel 40. The threaded sleeve 42 and the mounting partition 43 are rotationally connected.
