The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0038] like Figures 1 to 7 As shown, a laser level accessory of the present invention comprises: a seat body 1, an oil storage chamber 21 and a shock absorbing chamber 7 are sequentially arranged inside the seat body 1 from left to right, the oil storage chamber 21 and the shock absorbing chamber 7 are both filled with shock absorbing fluid, and the oil storage chamber 21 and the shock absorbing chamber 7 are communicated, and the oil can flow into the shock absorbing chamber 7 by applying pressure to the oil storage chamber 21 or the shock absorbing chamber 7;

[0039] The shock absorbing chamber 7 is movably connected with a support plate 5 for horizontally supporting the laser level, a lifting assembly 4 installed on the shock absorbing chamber 7, and a shock absorbing plate 6 slidably connected to the lifting assembly 4. When the shock absorbing plate 6 is performing shock absorption, it will slide on the surface of the lifting assembly 4, and the shock absorbing plate 6 slides inside the shock absorbing chamber 7;

[0040] An adjusting component 2 for adjusting the size of the oil storage chamber 21; the adjusting component 2 is connected to the lifting component 4 through a transmission component 3; the adjusting component 2 divides the oil storage chamber 21 into two cavities, an air chamber and an oil chamber, and the sizes of the air chamber and the oil chamber can be adjusted. Correspondingly, an air inlet is provided outside the air chamber, and an oil inlet is provided outside the oil chamber; the adjusting component 2 is connected to the lifting component 4 through a transmission component 3, and when the lifting component 4 rotates, the adjusting component 2 is driven to rotate by the transmission component 3, and the rotation direction is opposite to the rotation direction of the lifting component 4, a fixing component 8 for fixing the laser level, and a limit component 9, the lifting component 4 drives the fixing component 8 to fix the laser level, and can also drive the fixing component 8 for fixing the laser level, and the adjusting component 2 to adjust the space inside the oil storage chamber 21, and when the lifting component 4 rotates, it drives the fixing component 8 to squeeze the support plate 5, so that the support plate 5 moves downward, thereby adjusting the height of the laser level;

[0041] The lifting assembly 4 includes: a threaded rod 41 rotatably mounted on the seat body 1, a limiting rod 42 fixedly mounted on the seat body 1, the threaded rod 41 is threadedly connected to the lifting plate 81, and the limiting rod 42 penetrates the lifting plate 81, so that when the threaded rod 41 rotates, the lifting plate 81 can be driven to move up and down under the limit of the limiting rod 42;

[0042] The adjusting component 2 includes: a floating plate 24 for separating the space of the oil storage chamber 21, an adjusting plate 23 for adjusting the position of the floating plate 24, and an adjusting rod 22, wherein the adjusting rod 22 is a screw rod and is threadedly connected to the adjusting plate 23; the adjusting component 2 also includes: a fixing seat 25 fixedly mounted on the adjacent surface of the adjusting plate 23 and the floating plate 24, an adjusting spring 26 fixedly mounted on the fixing seat 25, and the adjusting spring 26 is connected to the adjusting plate 23 and the floating plate 24 through the fixing seat 25, so that the floating plate 24 can move within a certain range. When the oil in the oil storage chamber 21 is injected into the shock absorbing chamber 7, the adjusting spring 26 is deformed and pushes the floating plate 24 toward the liquid level in the oil storage chamber 21, so as to ensure the stability of the liquid level at all times and avoid the oil shaking in the oil storage chamber 21, which causes the seat body 1 to be unstable and affects the stability of the laser level.

[0043] The transmission assembly 3 includes: a pulley 2 35 fixedly connected to the threaded rod 41, a transmission belt 34 and a pulley 1 33 for driving the adjusting rod 22 to rotate, a transmission gear 2 32 for changing the rotation direction of the threaded rod 41, and a transmission gear 1 31. When the adjusting rod 22 rotates, the pulley 2 35 is driven to rotate by the pulley 1 33 and the transmission belt 34. The pulley 2 35 is fixedly connected to the transmission gear 1 31, and can drive the transmission gear 1 31 to rotate. The transmission gear 1 31 is meshed with the transmission gear 2 32. According to the transmission characteristics of the gears, the rotation directions of the transmission gear 1 31 and the transmission gear 2 32 are necessarily opposite, thereby achieving that, under the condition of transmission, the threaded rod 41 and the adjusting rod 22 rotate in opposite directions.

[0044] Since the specifications of laser levels are different, the heights that need to be adjusted are also different according to the actual situation on site, so the support plate 5 needs to be adjusted up and down.

[0045] The fixing assembly 8 includes: a clamping plate 84 for fixing the laser level, the clamping plate 84 is provided with two groups of return springs 86 for driving the clamping plate 84 to return to its original position, a slide groove 85 provided on the support plate 5, two ends of the return spring 86 are respectively connected to the clamping plate 84 and the slide groove 85, the slide groove 85 is used for connecting the clamping plate 84 and the support plate 5, a lifting plate 81 threadedly connected to the threaded rod 41, a fixing rod 82 fixedly connected to the lifting plate 81, a guide block 83 fixedly installed on the clamping plate 84, and the guide block 83. 3 is divided into a guiding section and an extruding section, the guiding section is an inclined contact surface with the fixing rod 82, and the extruding section is a vertical contact surface with the fixing rod 82. When the lifting plate 81 is lifted or lowered, the fixing rod 82 is driven to abut against the guide block 83, so that the clamping plate 84 fixes the laser level. The support plate 5 is tightly connected to the threaded rod 41. Under the extrusion of the lifting plate 81, it will slide on the surface of the threaded rod 41, and when the lifting plate 81 is not extruded, it will be fixed, thereby achieving the adjustment effect on the support plate 5.

[0046] When the pulley 2 35 rotates, it drives the threaded rod 41 to rotate, so as to drive the support plate 5 to adjust its height; the pulley 2 35 simultaneously drives the adjusting rod 22 to rotate through the transmission assembly 3, so as to adjust the space inside the oil storage chamber 21, and then injects the oil inside the oil storage chamber 21 into the shock absorbing chamber 1 7, so as to support the height of the support plate 5 after adjustment, and when the lifting plate 81 does not squeeze the support plate 5, the support plate 5 can be lifted up to adjust its height, and drive the fixing assembly 8 to fix the laser level.

[0047] The present application adjusts the support plate 5 and installs and fixes the laser level during the adjustment process, so that after the laser level is installed on the surface of the support plate 5, its horizontal height can also be adjusted, so that the oil in the oil storage chamber 21 and the shock absorbing chamber 7 can be converted back and forth, resulting in better effect.

[0048] When in use, the threaded rod 41 is rotated to drive the lifting plate 81 to move up and down on the surface of the threaded rod 41. At the same time, the limiting rod 42 penetrates the lifting plate 81, and can limit the lifting plate 81 when it slides on the surface of the threaded rod 41. When the lifting plate 81 moves, the fixing rod 82 abuts against the guide block 83 and moves from the guide section to the extrusion section. Under the guidance of the guide section, the clamping plate 84 is pushed toward the laser level for clamping, and the pressure on the laser level is ensured in the extrusion section. At this time, the lifting plate 81 can continue to move downward to squeeze the support plate 5 and adjust the height of the support plate 5.

[0049] Another point is that when the support plate 5 is adjusted, the support plate 5 rises, and oil needs to be injected into the shock absorbing chamber 7. Conversely, when the support plate 5 is lowered, the oil will be injected into the oil storage chamber 21. Therefore, when the height of the laser level cannot be confirmed according to the actual situation, the amount of oil in the shock absorbing chamber 7 cannot be confirmed either. Therefore, the oil storage chamber 21 can be adaptively adjusted according to the actual situation. In addition, when the threaded rod 41 rotates forward, the adjusting rod 22 can be reversed through the transmission assembly 3 to achieve that when the support plate 5 is lowered, the adjusting plate 23 rises to expand the oil chamber space, so that excess oil in the shock absorbing chamber 7 flows into the oil storage chamber 21. Conversely, when the support plate 5 rises, the adjusting plate 23 descends to compress the oil in the oil chamber and enter the shock absorbing chamber 7, thereby supporting the support plate 5 and achieving a good adjustment effect.

[0050] Regarding the above supplement, the laser level is fixed on the support plate 5. When the base 1 is tilted, the liquid level inside the shock absorbing chamber 7 will be adjusted adaptively, and the support plate 5 will be adjusted accordingly under the influence of the liquid level, thereby ensuring the level of the support plate 5 and further ensuring the horizontal accuracy of the laser level.

[0051] On the one hand, the present application adjusts the oil volume inside the shock absorbing chamber 7 and the oil storage chamber 21, and adjusts the height of the laser level. By setting the oil volume, it is possible to avoid small vibrations being transmitted to the laser level, causing the laser level to shake during use. On the other hand, after the adjustment, the laser level can be fixed so that it will not shake during use, further enhancing its stability during use.

[0052] When the support plate 5 is adjusted horizontally, interference occurs between the support plate 5 and the threaded rod 41 , causing the support plate 5 to be unable to be adjusted.

[0053] The limiting assembly 9 includes: an elastic member 91 fixedly connected to the support plate 5, the elastic member 91, a fixing sleeve 92 fixedly connected to the elastic member 91, and a sealing member 93 for sealing the gap between the fixing sleeve 92 and the support plate 5. The support plate 5 is sleeved on the threaded rod 41 through the fixing sleeve 92. When the support plate 5 is offset, the fixing sleeve 92 is adaptively adjusted through the elastic member 91 to ensure that the displacement of the support plate 5 will not interfere.

[0054] The base 1 is inevitably vibrated when in use, and the vibration may cause the accuracy of the laser level to decrease, so the laser level needs to be vibration-damped.

[0055] Shock-absorbing assembly 10: to reduce the vibration of the seat body 1, the shock-absorbing assembly 10 includes: a shock-absorbing leg 1001 fixedly mounted on the shock-absorbing plate 6, a shock-absorbing chamber 1002 opened on the shock-absorbing leg 1001, the shock-absorbing chamber 1002 is filled with shock-absorbing oil, a piston 1003 slidably connected to the shock-absorbing chamber 1002, and a shock-absorbing leg 1004 fixedly connected to the piston 1003, the shock-absorbing plate 6 and the piston 1003 are provided with flow paths for the circulation of shock-absorbing oil on the surface, the shock-absorbing leg 1004 reduces vibration inside the shock-absorbing chamber 1002 through the piston 1003, and can reduce small vibrations, while large vibrations will drive the shock-absorbing plate 6 to reduce vibrations inside the shock-absorbing chamber 1002 through the shock-absorbing leg 1001, and the shock-absorbing effect is good.
