[0015] A laser level for construction and its using method. The using method of the laser level for construction includes the following steps:

[0016] Step 1: Place the device on the ground and start the main telescopic rod. The main telescopic rod drives the lifting shell to move upward. The lifting shell drives the bearing platform to move upward. The bearing platform drives the laser level to move upward. During the upward movement of the bearing platform, the bearing platform drives the secondary telescopic rod to move upward. The secondary telescopic rod drives the PVC board to move upward. During the upward movement of the PVC board, the air flow inside the circular shell can enter the inside of the vertical shell through the first telescopic tube. The air flow causes the concave rod inside the vertical shell to move downward. The concave rod drives the special-shaped plate to move downward. The special-shaped plate drives the flexible cleaning plate to move downward. At the same time, when the special-shaped plate moves down to the top of the arc-shaped capsule, the special-shaped plate will squeeze the arc-shaped capsule, so that the air pressure inside the arc-shaped capsule enters the inside of the arc-shaped shell through the connecting tube. The air pressure causes the arc-shaped rod inside the arc-shaped shell to slide. The arc-shaped rod drives the connecting block to move. The connecting block drives the scraping block to move;

[0017] Step 2: When the PVC board moves upward, a negative pressure will be generated in the area at the bottom end of the circular shell. The negative pressure enters the inside of the dust suction shell through the second telescopic tube. The negative pressure moves from the dust suction shell to the outside of the special-shaped tube. And when the negative pressure disappears, affected by the elastic deformation of the first reset spring, the first reset spring makes the first conical block move upward;

[0018] Step 3: When the lifting shell moves upward, the lifting shell drives the second reset spring to move upward. The second reset spring drives the special-shaped block to move upward. During the upward movement of the special-shaped block, it contacts the conical slider, causing the conical slider to slide into the inside of the liquid storage tube. The lubricating liquid inside the liquid storage tube flows out and moves to the top of the lifting shell. At the same time, because the contact surface between the conical slider and the special-shaped block is relatively rough, the conical slider will generate a downward pressure on the special-shaped block, enabling the special-shaped block to move downward. The special-shaped block drives the rotating rod to move downward. Restricted by the lifting shell, the rotating rod drives the pressing plate to move horizontally. The pressing plate drives the sponge strip to move horizontally;

[0019] Step 4: During the downward movement of the concave rod inside the vertical shell, the air flow inside the vertical shell enters the inside of the sealing capsule through the fixed rod. At the same time, when the special-shaped block contacts the conical slider, the special-shaped block drops. The special-shaped block drives the sliding rod to drop. The sliding rod drives the lifting plate to drop inside the inner cavity of the lifting shell, so that the air pressure inside the lifting shell enters the inside of the sealing capsule through the elastic tube.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the device is placed on the ground and the main telescopic rod is started. The main telescopic rod drives the lifting shell to move upward. The lifting shell drives the bearing platform to move upward. The bearing platform drives the laser level to move upward, so that the laser level can measure building areas at different heights. During the upward movement of the bearing platform, the bearing platform drives the secondary telescopic rod to move upward. The secondary telescopic rod drives the polyvinyl chloride plate to move upward. During the upward movement of the polyvinyl chloride plate, the air flow inside the circular shell can enter the interior of the vertical shell through the first telescopic tube. The air flow causes the concave rod inside the vertical shell to move downward. The concave rod drives the special-shaped plate to move downward. The special-shaped plate drives the flexible cleaning plate to move downward, so that the flexible cleaning plate can clean the measuring mirror surface of the laser level, preventing dust particles at high altitudes from adhering to the mirror surface and affecting the measurement accuracy of the laser level. At the same time, when the special-shaped plate moves down to the top of the arc-shaped bladder, the special-shaped plate will squeeze the arc-shaped bladder, so that the air pressure inside the arc-shaped bladder enters the interior of the arc-shaped shell through the connecting tube. The air pressure causes the arc-shaped rod inside the arc-shaped shell to slide. The arc-shaped rod drives the connecting block to move. The connecting block drives the scraping block to move. After the flexible cleaning plate finishes cleaning, the dust particles will adhere to the outer surface of the flexible cleaning plate. Due to the movement of the scraping block, the dust particles are scraped off the outer surface of the flexible cleaning plate, enhancing the cleaning effect of the flexible cleaning plate.

[0022] (2) In the present invention, because the material of the polyvinyl chloride plate is polyvinyl chloride, it can prevent a gap from being generated between the circular shell and the polyvinyl chloride plate during the upward movement of the inner wall of the circular shell. Therefore, when the polyvinyl chloride plate moves upward, a negative pressure will be generated in the area at the bottom of the circular shell. The negative pressure enters the interior of the dust suction shell through the second telescopic tube. The negative pressure moves outward from the dust suction shell to the outside of the special-shaped tube, so that the dust particles scraped off by the scraping block can be absorbed into the interior of the dust suction shell, preventing the dust particles from adhering to the mirror surface of the laser level again, further enhancing the measurement accuracy of the laser level. And when the negative pressure disappears, affected by the elastic deformation of the first return spring, the first return spring causes the first conical block to move upward, and the first conical block blocks the pipe orifice of the special-shaped tube, preventing the dust that has entered the interior of the dust suction shell from escaping from the interior of the dust suction shell, further preventing the dust from adhering to the mirror surface of the laser level again.

[0023] (3) In the present invention, when the lifting shell moves upward, the lifting shell drives the second return spring to move upward, and the second return spring drives the special-shaped block to move upward. During the upward movement of the special-shaped block, it contacts the conical slider, causing the conical slider to slide into the interior of the liquid storage tube, no longer blocking the liquid storage tube. The lubricating liquid inside the liquid storage tube flows out and moves to the top of the lifting shell, thereby lubricating the track of the guide rail shell, enhancing the lifting stability of the lifting shell, preventing the laser level from shaking during the rising process, further enhancing the measurement accuracy of the laser level. At the same time, because the contact surface between the conical slider and the special-shaped block is relatively rough, the conical slider generates a downward pressure on the special-shaped block, enabling the special-shaped block to move downward. The special-shaped block drives the rotating rod to move downward. Restricted by the clamping position of the lifting shell, the rotating rod drives the pressing plate to move horizontally, and the pressing plate drives the sponge strip to move horizontally, so that the sponge strip contacts the inner wall of the guide rail shell, further enhancing the coating effect of the lubricating liquid, improving the utilization rate of the lubricating liquid, and preventing waste.

[0024] (4) In the present invention, during the upward movement of the bearing platform, due to the setting of the sealing capsule, it can prevent external dust from entering the interior of the guide rail shell. And when the concave rod moves downward inside the vertical shell, the air flow inside the vertical shell enters the interior of the sealing capsule through the fixed rod, thereby causing the sealing capsule to expand, preventing dust particles from entering the interior of the guide rail shell through the gap between the bearing platform and the sealing capsule during the upward movement of the bearing platform, affecting the stability of the bearing platform driving the laser level to rise, and enhancing the measurement accuracy of the laser level from the side. At the same time, when the special-shaped block contacts the conical slider, the special-shaped block falls, the special-shaped block drives the sliding rod to fall, and the sliding rod drives the lifting plate to fall inside the cavity of the lifting shell, causing the air pressure inside the lifting shell to enter the interior of the sealing capsule through the elastic tube, further enhancing the expansion effect of the sealing capsule.

[0025] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] A dust suction component 77 is provided at the bottom of the bearing platform 73. The dust suction component 77 includes a dust suction shell 771 fixedly connected to the bottom of the bearing platform 73. A number of special-shaped pipes 772 communicate with the top side of the bearing platform 73 close to the arc-shaped shell 765.

A number of vertical rods 773 are fixedly connected to the bottom of the inner wall of the dust suction shell 771. The purpose of this setting is to limit the lifting of the first conical block 775.

The bottom of the first return spring 774 is fixedly connected to the bottom of the inner wall of the dust suction shell 771. The bottom of the dust suction shell 771 communicates with a second telescopic pipe 776. One end of the second telescopic pipe 776 communicates with the bottom end side of the circular shell 753.

[0049] Place the device on the ground and start the main telescopic rod 71. The main telescopic rod 71 drives the lifting shell 72 to move upward. The lifting shell 72 drives the bearing platform 73 to move upward. The bearing platform 73 drives the laser level 74 to move upward, so that the laser level 74 can measure construction areas at different heights. During the upward movement of the bearing platform 73, the bearing platform 73 drives the secondary telescopic rod 751 to move upward. The secondary telescopic rod 751 drives the polyvinyl chloride plate 752 to move upward. During the upward movement of the polyvinyl chloride plate 752, the air flow inside the circular shell 753 can enter the inside of the vertical shell 756 through the first telescopic pipe 755. The air flow causes the concave rod 761 inside the vertical shell 756 to move downward. The concave rod 761 drives the special-shaped plate 763 to move downward. The special-shaped plate 763 drives the flexible cleaning plate 764 to move downward, so that the flexible cleaning plate 764 can clean the measuring mirror surface of the laser level 74, preventing dust particles at high altitudes from adhering to the mirror surface and affecting the measuring accuracy of the laser level 74. At the same time, when the special-shaped plate 763 moves downward to the top of the arc-shaped bladder 766, the special-shaped plate 763 will squeeze the arc-shaped bladder 766, so that the air pressure inside the arc-shaped bladder 766 enters the inside of the arc-shaped shell 765 through the connecting pipe 767. The air pressure causes the arc-shaped rod 768 inside the arc-shaped shell 765 to slide. The arc-shaped rod 768 drives the connecting block 769 to move. The connecting block 769 drives the scraping block 7611 to move. After the flexible cleaning plate 764 finishes cleaning, the dust particles will adhere to the outer surface of the flexible cleaning plate 764. Due to the movement of the scraping block 7611, the dust particles are scraped off the outer surface of the flexible cleaning plate 764, enhancing the cleaning effect of the flexible cleaning plate 764.

[0050] Since the material of the PVC board 752 is polyvinyl chloride, it can prevent a gap from being generated between the inner wall of the circular shell 753 and the PVC board 752 during the upward movement of the inner wall of the circular shell 753. Thus, when the PVC board 752 moves upward, a negative pressure will be generated in the area at the bottom end of the circular shell 753. The negative pressure enters the interior of the dust suction shell 771 through the second telescopic tube 776, and the negative pressure moves from the dust suction shell 771 to the outside of the special-shaped tube 772. Thereby, the dust particles scraped by the scraping block 7611 can be absorbed into the interior of the dust suction shell 771, preventing the dust particles from adhering to the mirror surface of the laser level 74 again, further enhancing the measurement accuracy of the laser level 74. And when the negative pressure disappears, affected by the elastic deformation of the first return spring 774, the first return spring 774 causes the first tapered block 775 to move upward, and the first tapered block 775 seals the pipe orifice of the special-shaped tube 772, preventing the dust that has entered the interior of the dust suction shell 771 from escaping from the interior of the dust suction shell 771, and further preventing the dust from adhering to the mirror surface of the laser level 74 again.

A sliding rod 782 is fixedly connected to the top of the lifting plate 781. The top end of the sliding rod 782 penetrates through the lifting shell 72 and extends to the outside of the lifting shell 72.

[0055] A laser level for construction and its using method. The using method of the laser level for construction includes the following steps:

[0056] Step 1: Place the device on the ground and start the main telescopic rod 71. The main telescopic rod 71 drives the lifting shell 72 to move upward. The lifting shell 72 drives the bearing platform 73 to move upward. The bearing platform 73 drives the laser level 74 to move upward. During the upward movement of the bearing platform 73, the bearing platform 73 drives the secondary telescopic rod 751 to move upward. The secondary telescopic rod 751 drives the polyvinyl chloride plate 752 to move upward. During the upward movement of the polyvinyl chloride plate 752, the air flow inside the circular shell 753 can enter the inside of the vertical shell 756 through the first telescopic tube 755. The air flow makes the concave rod 761 inside the vertical shell 756 move downward. The concave rod 761 drives the special-shaped plate 763 to move downward. The special-shaped plate 763 drives the flexible cleaning plate 764 to move downward. At the same time, when the special-shaped plate 763 moves down to the top of the arc-shaped capsule 766, the special-shaped plate 763 will squeeze the arc-shaped capsule 766, so that the air pressure inside the arc-shaped capsule 766 enters the inside of the arc-shaped shell 765 through the connecting tube 767. The air pressure makes the arc-shaped rod 768 inside the arc-shaped shell 765 slide. The arc-shaped rod 768 drives the connecting block 769 to move. The connecting block 769 drives the scraping block 7611 to move;

[0057] Step 2: When the polyvinyl chloride plate 752 moves upward, a negative pressure will be generated in the area at the bottom end of the circular shell 753. The negative pressure enters the inside of the dust suction shell 771 through the second telescopic tube 776. The negative pressure moves outward from the dust suction shell 771 to the outside of the special-shaped tube 772. And when the negative pressure disappears, affected by the elastic deformation of the first reset spring 774, the first reset spring 774 makes the first conical block 775 move upward;

[0058] Step 3: When the lifting housing 72 moves upward, the lifting housing 72 drives the second return spring 783 to move upward. The second return spring 783 drives the special-shaped block 784 to move upward. During the upward movement of the special-shaped block 784, it comes into contact with the conical slider 7815, causing the conical slider 7815 to slide into the interior of the liquid storage tube 7812. The lubricating liquid inside the liquid storage tube 7812 flows outwards and moves to the top of the lifting housing 72. At the same time, because the contact surface between the conical slider 7815 and the special-shaped block 784 is relatively rough, the conical slider 7815 generates a downward pressure on the special-shaped block 784, enabling the special-shaped block 784 to move downward. The special-shaped block 784 drives the rotating rod 785 to move downward. Due to the blocking of the lifting housing 72, the rotating rod 785 drives the pressing plate 787 to move horizontally, and the pressing plate 787 drives the sponge strip 788 to move horizontally;

[0059] Step 4: When the concave rod 761 moves downward inside the vertical housing 756, the air flow inside the vertical housing 756 enters the interior of the sealing capsule 7811 through the fixed rod 7813. At the same time, when the special-shaped block 784 comes into contact with the conical slider 7815, the special-shaped block 784 drops. The special-shaped block 784 drives the sliding rod 782 to drop, and the sliding rod 782 drives the lifting plate 781 to drop inside the inner cavity of the lifting housing 72, causing the air pressure inside the lifting housing 72 to enter the interior of the sealing capsule 7811 through the elastic tube 7810.

[0060] During use, when the lifting housing 72 moves upward, the lifting housing 72 drives the second return spring 783 to move upward. The second return spring 783 drives the special-shaped block 784 to move upward. During the upward movement of the special-shaped block 784, it comes into contact with the conical slider 7815, causing the conical slider 7815 to slide into the interior of the liquid storage tube 7812 and no longer block the liquid storage tube 7812. The lubricating liquid inside the liquid storage tube 7812 flows outwards and moves to the top of the lifting housing 72, thereby lubricating the track of the guide rail housing 6, enhancing the lifting stability of the lifting housing 72, preventing the laser level 74 from shaking during the ascending process, further enhancing the measurement accuracy of the laser level 74. At the same time, because the contact surface between the conical slider 7815 and the special-shaped block 784 is relatively rough, the conical slider 7815 generates a downward pressure on the special-shaped block 784, enabling the special-shaped block 784 to move downward. The special-shaped block 784 drives the rotating rod 785 to move downward. Due to the blocking of the lifting housing 72, the rotating rod 785 drives the pressing plate 787 to move horizontally, and the pressing plate 787 drives the sponge strip 788 to move horizontally, thereby causing the sponge strip 788 to come into contact with the inner wall of the guide rail housing 6, further enhancing the coating effect of the lubricating liquid, improving the utilization rate of the lubricating liquid, and preventing waste.

[0061] When the carrier table 73 rises, due to the setting of the sealing capsule 7811, it can prevent external dust from entering the inside of the guide rail housing 6. And when the concave rod 761 moves downward inside the vertical housing 756, the air flow inside the vertical housing 756 enters the inside of the sealing capsule 7811 through the fixing rod 7813, so that the sealing capsule 7811 expands, preventing dust particles from entering the inside of the guide rail housing 6 through the gap between the carrier table 73 and the sealing capsule 7811 during the rising process of the carrier table 73, which affects the stability of the carrier table 73 driving the laser level 74 to rise, and enhancing the measurement accuracy of the laser level 74 on the side. At the same time, when the special-shaped block 784 contacts the conical slider 7815, the special-shaped block 784 drops, the special-shaped block 784 drives the sliding rod 782 to drop, and the sliding rod 782 drives the lifting plate 781 to drop inside the inner cavity of the lifting housing 72, so that the air pressure inside the lifting housing 72 enters the inside of the sealing capsule 7811 through the elastic tube 7810, further enhancing the expansion effect of the sealing capsule 7811.

The main telescopic rod (71) drives the lifting housing (72) to move upward. The lifting housing (72) drives the bearing platform (73) to move upward. The bearing platform (73) drives the laser level (74) to move upward. And during the upward movement of the bearing platform (73), the bearing platform (73) drives the secondary telescopic rod (751) to move upward. The secondary telescopic rod (751) drives the polyvinyl chloride plate (752) to move upward. During the upward movement of the polyvinyl chloride plate (752), the air flow inside the circular housing (753) can enter the inside of the vertical housing (756) through the first telescopic tube (755). The air flow makes the concave rod (761) inside the vertical housing (756) move downward. The concave rod (761) drives the special-shaped plate (763) to move downward. The special-shaped plate (763) drives the flexible cleaning plate (764) to move downward. At the same time, when the special-shaped plate (763) moves down to the top of the arc-shaped capsule (766), the special-shaped plate (763) will squeeze the arc-shaped capsule (766), so that the air pressure inside the arc-shaped capsule (766) enters the inside of the arc-shaped housing (765) through the connecting tube (767). The air pressure makes the arc-shaped rod (768) inside the arc-shaped housing (765) slide. The arc-shaped rod (768) drives the connecting block (769) to move.

The negative pressure enters the inside of the dust suction housing (771) through the second telescopic tube (776). The negative pressure moves from the dust suction housing (771) to the outside of the special-shaped tube (772). And when the negative pressure disappears, affected by the elastic deformation of the first return spring (774), the first return spring (774) makes the first conical block (775) move upward; Step Three: When the lifting housing (72) moves upward, the lifting housing (72) drives the second return spring (783) to move upward. The second return spring (783) drives the special-shaped block (784) to move upward. During the upward movement of the special-shaped block (784), it contacts the conical slider (7815), causing the conical slider (7815) to slide into the interior of the liquid storage tube (7812). The lubricating liquid inside the liquid storage tube (7812) flows outwards and moves to the top of the lifting housing (72). At the same time, because the contact surface between the conical slider (7815) and the special-shaped block (784) is relatively rough, the conical slider (7815) generates a downward pressure on the special-shaped block (784), enabling the special-shaped block (784) to move downward.
