Description
Technical Field

[0002] A laser level is a measuring tool that uses a laser beam for precise horizontal or vertical positioning. It is widely used in construction, interior decoration, furniture arrangement, pipe laying, mechanical installation and other fields.
[0003] When using a laser level in indoor construction, due to poor indoor ventilation, dust impurities are not easy to dissipate after being raised. At the same time, the vertical laser irradiation port of some laser levels is tilted, and the raised dust impurities are easy to accumulate at the vertical laser irradiation port where the vertical laser is irradiated. The accumulated dust impurities block the vertical laser, causing the laser emitted by the laser level to be broken, and it is impossible to form an accurate reference line, which affects the positioning accuracy during construction or installation, and may cause deviations in operations such as wall laying, floor laying, and furniture installation.
[0004] Furthermore, existing laser levels have a pendulum inside for keeping the laser level. When the laser level falls accidentally, the pendulum inside is in a suspended state when in use. When the laser level falls, the pendulum will swing violently, causing the irradiated laser to shift. When the degree of offset of the pendulum is small, the staff cannot determine whether the irradiated laser is offset, resulting in the use of an offset and tilted laser for calibration and alignment during construction, which reduces construction accuracy.

[0029] It also includes a connecting ring 4, a buffer plate 5, a cleaning brush 6, a blowing component, a movable component and a detection system; a connecting ring 4 is movably arranged on the outer cover shell 1; four buffer plates 5 distributed in a ring array are arranged on the connecting ring 4; a debris discharge port 5001 is opened at the lower part of each buffer plate 5; a cleaning brush 6 is fixedly connected to each buffer plate 5; a blowing component is connected to each buffer plate 5; a movable component is connected to the outer cover shell 1; and a detection system is arranged on the outer cover shell 1.
[0030] The blowing assembly includes an airbag 101, a one-way membrane 102 and a one-way air tube 103; each buffer plate 5 is fixedly connected to two airbags 101 on the side facing the outer cover shell 1; all the airbags 101 are jointly attached to the outer side of the outer cover shell 1; each cleaning brush 6 is located between two adjacent airbags 101; each buffer plate 5 is provided with two air holes 5002; each airbag 101 is connected to the outside through the corresponding air hole 5002; a one-way membrane 102 is fixedly connected in each air hole 5002; each airbag 101 is fixedly connected and connected to a number of one-way air tubes 103.
[0031] Furthermore, in order to clean the dust and impurities on the cleaning brush 6 and prevent the cleaning brush 6 from carrying the dust and impurities and rubbing against the vertical opening 1001 , each one-way air pipe 103 is arranged to be inclined toward the cleaning brush 6 .
[0032] Furthermore, in order to enhance the effect of the one-way air pipe 103 in blowing away dust impurities, that is, to increase the velocity of the airflow blown out from the one-way air pipe 103, each one-way air pipe 103 is configured as a constricted structure.
[0033] The movable component includes a fixed ring 201 and a movable ring 202; the fixed ring 201 is fixedly connected to the outer side of the outer cover shell 1; a plurality of upper protrusions 20101 distributed in a circular array are arranged on the upper side of the fixed ring 201; a movable ring 202 is commonly fixedly connected to the lower side of all buffer plates 5; a plurality of lower protrusions 20201 distributed in a circular array are arranged on the lower side of the movable ring 202; the upper protrusions 20101 and the lower protrusions 20201 are arranged in a staggered state.
[0034] Furthermore, in order to facilitate the staff to rotate the buffer plate 5, each buffer plate 5 is provided with a plurality of convex strips 5003.
[0035] It also includes a rubber block 7; four rubber blocks 7 distributed in a ring array are fixedly connected to the upper side of the outer cover shell 1; all rubber blocks 7 are located outside the horizontal bubble 1003, and the upper end of the rubber block 7 is higher than the upper end of the horizontal bubble 1003.
[0036] The present invention uses the buffer plate 5 to drive the cleaning brush 6 to clean the vertical opening 1001 where dust and impurities are easily accumulated, thereby solving the problem that dust and impurities accumulate in the vertical opening 1001 during the construction process, causing the laser emitted by the laser emitter 3 to be disconnected. The specific process is as follows:
[0037] The first step is to install the battery 2 on the outer cover shell 1 to power the laser emitter 3 before using the laser level. When using the laser level for calibration, first place the level relative to the construction site, and determine whether the laser level is in a horizontal state through the level bubble 1003. Then control the laser emitter 3 to irradiate two mutually perpendicular laser beams, horizontal and vertical, from the vertical port 1001 and the horizontal port 1002 respectively, so as to calibrate the construction site.
[0038] In the second step, during the construction process, when dust impurities in the air fall onto the vertical port 1001, the laser irradiated through the vertical port 1001 is blocked by the dust impurities and the line is broken. At this time, the staff holds all the buffer plates 5, and based on the view from top to bottom, the connecting ring 4 and all the buffer plates 5 are twisted clockwise on the outer cover shell 1, so that the buffer plate 5 drives the cleaning brush 6 to move to the vertical port 1001. Then the staff holds the buffer plate 5 and twists it repeatedly on the outer cover shell 1, so that the cleaning brush 6 is horizontally reciprocated on the vertical port 1001 to brush the vertical The vertical opening 1001 is cleaned to prevent dust and impurities from accumulating in the vertical opening 1001, and to avoid the disconnection of the laser irradiated to the construction site, thereby ensuring the calibration and positioning effect of the laser level. At the same time, this method is used to clean the vertical opening 1001, and the staff does not need to use tools to clean the vertical opening 1001, making it more convenient to clean the vertical opening 1001. During this process, the convex strip 5003 is used to increase the friction between the staff's palm and the buffer plate 5 to prevent the staff's palm from slipping when rotating the buffer plate 5.
[0039] In the third step, when the buffer plate 5 is rotated to drive the cleaning brush 6 to clean the vertical opening 1001, the buffer plate 5 drives the initially compressed airbag 101 to repeatedly pass through the vertical opening 1001. When the airbag 101 is stuck in the vertical opening 1001, it rebounds and resets. The internal volume of the airbag 101 increases to form a negative pressure, and the outside is sucked through the air hole 5002. At this time, the one-way membrane 102 is pushed open by the external airflow, and the external airflow enters the airbag 101 through the air hole 5002. When the buffer plate 5 drives the airbag 101 After passing through the vertical opening 1001, the airbag 101 is squeezed by the outer cover shell 1, and the gas inside the airbag 101 is sprayed toward the cleaning brush 6 through the one-way air pipe 103, and the dust impurities brushed off at the vertical opening 1001 and the dust impurities adhered to the cleaning brush 6 are blown out to the outside of the outer cover shell 1 through the impurity discharge port 5001, preventing the cleaning brush 6 from rubbing against the vertical opening 1001 with the dust impurities, thereby reducing the wear of the vertical opening 1001 during cleaning and enhancing the cleaning effect of the vertical opening 1001.
[0040] In the fourth step, when the buffer plate 5 is rotated to make the cleaning brush 6 clean the vertical opening 1001, all the buffer plates 5 drive the movable ring 202 to rotate together, so that the lower protrusion 20201 moves on the upper protrusion 20101 of the fixed ring 201, and when the lower protrusion 20201 moves to coincide with the apex of the upper protrusion 20101, the movable ring 202 drives all the buffer plates 5 to rise on the outer cover shell 1, and then drives the cleaning brush 6 to rise at the vertical opening 1001, and when the lower protrusion 20201 moves to be staggered with the apex of the upper protrusion 20101 above and below, the movable ring 202 drives all the buffer plates 5 to descend on the outer cover shell 1, and then drives the cleaning brush 6 to descend at the vertical opening 1001, so that the buffer plate 5 drives the cleaning brush 6 to perform lifting and brushing cleaning when passing through the vertical opening 1001, thereby further enhancing the cleaning effect of the vertical opening 1001.
[0041] The fifth step, after using the laser level, the staff will drive the buffer plate 5 to screw the air bag 101 to the vertical opening 1001 to prevent dust from accumulating at the vertical opening 1001 when the laser level is not in use. When the laser level falls accidentally, the buffer plate 5 and the air bag 101 provide doubly protection for the vertical opening 1001, thereby improving the protection effect of the laser level. At the same time, the rubber block 7 is used to protect the level bubble 1003 to prevent the level bubble 1003 from being broken and damaged. Example 2
[0042] On the basis of Example 1, Figure 4 and Figure 5 As shown, the detection system includes a rotating ring 301, a detection sheet 302, a fixed block 303 and a magnetic block 304; a rotating ring 301 is rotatably arranged on the outer cover shell 1; the rotating ring 301 is located on the lower side of the connecting ring 4; four detection sheets 302 distributed in a circular array are fixedly connected to the rotating ring 301; each detection sheet 302 is provided with a calibration groove 30201; four fixed blocks 303 distributed in a circular array are fixedly connected to the rotating ring 301; an extension portion 6001 is arranged on the upper part of each cleaning brush 6; all fixed blocks 303 are flush with all extension portions 6001; with the view from top to bottom as a reference, the side of each extension portion 6001 rotating counterclockwise is in contact with the adjacent fixed block 303; four magnetic blocks 304 distributed in a circular array are fixedly connected to the outer cover shell 1; all fixed blocks 303 and all magnetic blocks 304 are located on the same horizontal line.
[0043] Furthermore, in order to prevent the detection sheet 302 from being displaced together with the laser emitter 3 when the outer cover shell 1 falls, all the detection sheets 302 are located together on the inner side of all the buffer plates 5 and fit with the corresponding airbags 101 .
[0044] The present invention detects the laser emitted from the vertical opening 1001 in time through the detection sheet 302 after the laser level falls, thereby solving the problem that the laser emitter 3 is offset after the laser level falls, and the staff cannot judge whether the laser is offset, resulting in the problem that the laser emitted during construction is offset. The specific process is as follows:
[0045] In the fifth step of Example 1, when the laser level falls, the staff holds all the buffer plates 5, and with the view from top to bottom as the reference, twists all the buffer plates 5 on the outer cover shell 1 counterclockwise, driving the cleaning brush 6 to rotate counterclockwise on the outer cover shell 1 to the vertical opening 1001, so that the extension portion 6001 pushes the fixed block 303 to move, and the fixed block 303 is adsorbed and fixed by the magnetic block 304, so that the rotating ring 301 drives all the detection plates 302 to move to the outside of all the vertical openings 1001, and aligns the calibration groove 30201 with the corresponding vertical opening 1001, and then the staff twists all the buffer plates 5 on the outer cover shell 1 clockwise to between two adjacent vertical openings 1001, thereby driving the corresponding cleaning brush 6 to rotate. To between two adjacent vertical openings 1001, the staff then turns on the laser level to make the laser emitted by the laser emitter 3 pass through the vertical opening 1001 and the calibration groove 30201 to irradiate the construction site. When the laser level falls, causing the laser emitter 3 to deviate, the laser irradiated to the construction site is detected through the calibration groove 30201. The staff observes whether there is a break at the intersection of the laser emitted by the vertical opening 1001 and the horizontal opening 1002, so as to determine whether the laser emitted by the laser emitter 3 is offset, thereby preventing the staff from being unable to determine whether the laser is offset, avoiding the reduction of construction accuracy due to the offset of the irradiated laser during construction, and ensuring the calibration and positioning effect of the laser level.
[0046] After the inspection of the laser level is completed using the detection piece 302, the staff will turn all the buffer plates 5 on the outer cover shell 1 clockwise to make the extension part 6001 push the fixed block 303 to move, and separate the fixed block 303 from the magnetic block 304, so that the rotating ring 301 drives all the detection pieces 302 to move between two adjacent vertical openings 1001 to reset the detection pieces 302. Example 3
[0047] On the basis of Example 1, Figure 1 and Figure 6 As shown, a baffle 401 is also included; a baffle 401 is fixedly connected to the upper side of each buffer plate 5; and all baffles 401 are located above the corresponding air holes 5002.
[0048] When the staff rotates the buffer plate 5 to make the cleaning brush 6 clean the vertical opening 1001, the airbag 101 is repeatedly squeezed by the outer cover shell 1 and air is sucked out to the outside through the air hole 5002. When the staff rotates the buffer plate 5, the baffle 401 separates the staff's palm from the air hole 5002 on the upper part of the buffer plate 5, so that the outside air passes through the gap between the baffle 401 and the buffer plate 5 and enters the inside of the airbag 101 through the air hole 5002, preventing the staff from blocking the air hole 5002 when twisting the buffer plate 5, thereby preventing the airbag 101 from being unable to suck air out to the outside through the air hole 5002, thereby ensuring the blowing cleaning effect of the vertical opening 1001.
[0049] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
