Description

Technical Field

[0001] The invention relates to the technical field of levels, and in particular to a laser leveling device with a stable structure and an adjustment function. Background Art

[0002] Laser level is a high-precision measuring instrument that uses laser beams to replace the line of sight in traditional optical levels for measurement, which improves the efficiency and accuracy of measurement. The working principle of laser level is based on the monochromaticity and coherence of lasers. It emits a laser beam through a built-in laser. This laser beam passes through the optical system in the telescope tube and is emitted along the sighting axis to form a horizontal laser beam. The laser beam produces diffraction interference through the wave zone plate in front of the objective lens, thereby forming a clear light spot at the target for precise aiming.

[0003] Before using the laser level, it needs to be supported by a tripod. Generally, for stability, the laser level needs to be fixed to the tripod with bolts. The installation and disassembly process is relatively troublesome, and when the tripod is on the muddy ground, the tripod is prone to instability, which makes the level easy to be knocked over and damaged.

[0004] Therefore, it is necessary to design a laser leveling device with an adjustment function that is simple and convenient to install and has a stable structure. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art that the laser level is fixed to the tripod by bolts, the installation and disassembly process is cumbersome, and the tripod is easily unstable when on the muddy ground, so that the level is easily knocked over and damaged, the technical problem is: to provide a laser level device with an adjustment function that is simple and convenient to install and has a stable support structure.

[0006] The technical solution of the present invention is: a laser leveling device with a stable structure and an adjustment function, including a laser level, a supporting mechanism and a clamping mechanism. The lower side of the laser level is provided with a supporting mechanism for supporting and fixing, and the supporting mechanism is provided with a clamping mechanism for clamping and stabilizing.

[0007] Furthermore, the supporting mechanism includes a rotating cone foot, an upper plate, a lower plate, a forked leg, a central rod, a strut, a nut and a supporting foot. Three rotating cone feet are connected to the lower side of the laser level. The upper plate is clamped between the lower sides of the rotating cone feet. The lower side of the upper plate is rotationally connected to the lower plate via a damping, and the outer periphery of the lower plate is rotationally connected to three forked legs at evenly spaced intervals. The middle lower side of the lower plate is rotationally connected to the central rod, and the middle part of the central rod is threadedly connected to a nut. The nut and the forked leg are rotationally connected to the strut, and the lower side of the forked leg is rotationally connected to the supporting foot via a ball knot.

[0008] Furthermore, it also includes an air cushion, and the lower part of the forked legs is connected to the air cushion. The air cushion expands and contacts the ground to adapt to different ground surfaces and maintain stability.

[0009] Furthermore, it also includes limiting columns. Three limiting columns are connected to the lower side of the upper plate. Three grooves are opened on the lower plate. The grooves on the lower plate cooperate with the limiting columns to limit the rotation angle of the upper plate.

[0010] Furthermore, the clamping mechanism includes a fixed column, a separation arc plate, a fixed seat, a torsion spring, an angle clamp, an extrusion rod and a spring. The rear side of the upper plate is connected to a fixed column. The left and right separation arc plates are rotatably connected to the fixed column. The fixed column and the two separation arc plates thereon form a scissors shape, and the front parts of the separation arc plates are crossed. The outer periphery of the upper plate is rotatably connected to three fixed seats at even intervals. The fixed seats are rotatably connected to angle clamps. The angle clamps are engaged with the rotating cone feet. Torsion springs are connected between the angle clamps and the fixed seats connected to them. The angle clamps are in contact with the separation arc plates to stimulate An extrusion rod is slidably connected to the lower rear side of the optical level, a spring is connected between the laser level and the extrusion rod, the extrusion rod is in contact with the separation arc plate, the lower side of the extrusion rod is spherical, and the lower part of the extrusion rod is N-shaped; when the extrusion rod moves downward, the bottom spherical structure will squeeze the separation arc plate to rotate around the fixed column as the axis, and at this time the separation arc plate will squeeze the angle clamp to rotate outward, and when the spherical structure at the bottom of the extrusion rod is separated from the separation arc plate, the angle clamp rotates and resets under the action of the torsion spring to clamp the rotating cone foot, and then the N-shaped structure on the extrusion rod will limit the fixed separation arc plate, so that the separation arc plate cannot rotate.

[0011] Furthermore, it also includes an auxiliary mechanism, which includes a lifting rod, a reset bucket, a handle and a fixed plate. The upper rear side of the nut is connected to the lifting rod, and the upper side of the lifting rod is connected to the reset bucket. The reset bucket is wide at the top and narrow at the bottom. The rear side of the reset bucket is connected to the handle, which contacts and cooperates with the extrusion rod, and the lower side of the rear limiting column is connected to the fixed plate, and the fixed plate contacts and cooperates with the reset bucket. The upward movement of the nut will drive the lifting rod to move upward, thereby driving the reset bucket to move upward, thereby correcting the fixed plate and the limiting column, and then correcting the orientation of the upper plate, and at the same time driving the handle to move upward, at this time the handle will push the extrusion rod to move upward, and at this time the N-shaped structure of the extrusion rod will no longer limit the separation arc plate, and then the spherical structure of the extrusion rod will squeeze the separation arc plate to rotate with the fixed column as the axis, so that the rotation of the angle clamp block no longer jams the rotating cone foot.

[0012] Furthermore, a level is included, and three levels are arranged on the fixed plate.

[0013] Furthermore, it also includes a locking mechanism, which includes a square hole seat and a lifting plate. The fixed seat is connected to the square hole seat, and the square hole seat is clamped with a lifting plate, and the lifting plate is in contact with the forked leg.

[0014] Furthermore, it also includes a horizontal mechanism, which includes a notch cover and a weight handle. The front side of the laser level is rotatably connected to the notch cover, and the lower side of the notch cover is connected to the weight handle.

[0015] Furthermore, it also includes a fixing mechanism, which includes an adjusting plate and a fixing rod. The supporting feet are all slidably connected with the adjusting plates, and the adjusting plates are all connected with the fixing rods through threads.

[0016] The beneficial effects are: 1. When the laser level is placed on the upper plate, the rotating cone foot can be inserted into the upper plate to achieve rapid alignment and fixation. By cooperating with the extrusion rod and the separation arc plate, the angle clamp can automatically clamp the rotating cone foot and be restricted, thereby ensuring that the laser level is fixed and preventing the laser level from becoming loose.

[0017] 2. The present invention can control the rotation of the supporting foot through the ball knot to adapt to uneven ground. At the same time, it can also inflate the air cushion so that the air cushion expands and contacts the ground, thereby adapting to different ground surfaces and maintaining stability.

[0018] 3. After the laser level is used, the present invention will control the central rod to rotate so that the nut moves upward. The upward movement of the nut will drive the lifting rod to move upward, thereby correcting the orientation of the upper plate, and at the same time drive the handle to move upward, thereby pushing the extrusion rod to move upward, so that the angle clamp block can rotate and no longer get stuck on the rotating cone foot. At this time, the laser level can be easily removed.

[0019] 4. When the corner block of the present invention clamps the rotating cone foot, it can also penetrate into the square hole seat through the lifting plate, and at the same time, the bottom of the lifting plate is in contact with the forked leg for support. At this time, the lifting plate will limit and fix the corner block, thereby further ensuring the stability of the fixation.

[0020] 5. The present invention can protect the emission port of the laser level through the notch cover. At the same time, due to the weight effect, the position of the emission port of the laser level through the notch cover can be further detected to see the horizontal state of the laser level, thereby ensuring the accuracy of the laser level test.

DETAILED DESCRIPTION

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] A laser leveling device with a stable structure and adjustable function, such as Figure 1-Figure 6 As shown, it includes a laser level 1, a supporting mechanism 2 and a clamping mechanism 3. The lower side of the laser level 1 is provided with a supporting mechanism 2 for supporting and fixing, and the supporting mechanism 2 is provided with a clamping mechanism 3 for clamping firmly.

[0034] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the supporting mechanism 2 includes a rotating cone foot 20, an upper plate 21, a lower plate 22, a limiting column 23, a forked leg 24, a central rod 25, a support rod 26, a nut 27, an air cushion 28 and a supporting foot 29. The lower side of the laser level 1 is connected to three rotating cone feet 20, the lower side of the rotating cone feet 20 is clamped with an upper plate 21, the lower side of the upper plate 21 is connected to the lower plate 22 through a damping rotation, the lower side of the upper plate 21 is connected to three limiting columns 23, the lower plate 22 is provided with three grooves, and the grooves on the lower plate 22 and the limiting columns 23 are connected. In order to limit the rotation angle of the upper plate 21, the outer periphery of the lower plate 22 is rotatably connected with three forked legs 24 at evenly spaced intervals, the middle lower side of the lower plate 22 is rotatably connected with a central rod 25, the middle of the central rod 25 is threadedly connected with a nut 27, and a support rod 26 is rotatably connected between the nut 27 and the forked legs 24. The lower part of the forked legs 24 is connected with an air cushion 28, which expands and contacts the ground to adapt to different ground surfaces and maintain stability, and the lower side of the forked legs 24 is rotatably connected with a supporting foot 29 through a ball knot.

[0035] like Figure 1 and Figure 6 As shown, the clamping mechanism 3 includes a fixed column 31, a separation arc plate 32, a fixed seat 33, a torsion spring 34, an angle block 35, an extrusion rod 36 and a spring 37. The rear side of the upper plate 21 is connected to the fixed column 31, and the left and right separation arc plates 32 are rotatably connected to the fixed column 31. The fixed column 31 and the two separation arc plates 32 thereon form a scissor shape, and the front parts of the separation arc plates 32 are crossed. The outer periphery of the upper plate 21 is evenly spaced and rotatably connected to three fixed seats 33, and the fixed seats 33 are evenly spaced. A rotatable connection is provided with an angle clamp 35, which is engaged with the rotating cone foot 20, and a torsion spring 34 is connected between the angle clamp 35 and the fixed seat 33 connected to it. The angle clamps 35 are in contact with the separation arc plate 32, and an extrusion rod 36 is slidably connected to the lower rear side of the laser level 1. A spring 37 is connected between the laser level 1 and the extrusion rod 36, and the extrusion rod 36 is in contact with the separation arc plate 32. The lower side of the extrusion rod 36 is spherical, and the lower part of the extrusion rod 36 is N-shaped.

[0036] When using the device, the central rod 25 is controlled to rotate, so that the nut 27 moves downward, and the forked leg 24 is rotated and opened through the support rod 26, so as to provide support. At the same time, the support foot 29 can be controlled to rotate through the ball knot to adapt to uneven ground. At the same time, air can be inflated into the air cushion 28, and the air cushion 28 expands and contacts the ground, so as to adapt to different grounds and maintain stability. Then the laser level 1 can be placed on the upper plate 21. When the laser level 1 is placed on the upper plate 21, the rotating cone foot 20 can be inserted into the upper plate 21, so as to achieve rapid alignment and fixation. At the same time, the laser level The instrument 1 will also drive the extrusion rod 36 to move downward, and the spherical structure at the bottom of the extrusion rod 36 will squeeze the separation arc plate 32 to rotate around the fixed column 31. At this time, the separation arc plate 32 will squeeze the angle clamp 35 to rotate outward, and the torsion spring 34 will deform. When the spherical structure at the bottom of the extrusion rod 36 separates from the separation arc plate 32, the angle clamp 35 rotates and resets under the action of the torsion spring 34 to clamp the rotating cone foot 20. Then, the N-shaped structure at the bottom of the extrusion rod 36 will limit and fix the separation arc plate 32, so that the separation arc plate 32 cannot rotate, thereby ensuring that the laser level 1 is fixed and preventing the laser level 1 from loosening. Then, the instrument can be leveled using the foot screw of the level.

[0037] like Figure 1 and Figure 7 As shown, an auxiliary mechanism 4 is also included, which includes a lifting rod 41, a reset bucket 42, a handle 43, a fixing plate 44 and a spirit level 45. The upper rear side of the nut 27 is connected to the lifting rod 41, the upper side of the lifting rod 41 is connected to the reset bucket 42, the reset bucket 42 is wide at the top and narrow at the bottom, the rear side of the reset bucket 42 is connected to the handle 43, the handle 43 is in contact with the extrusion rod 36, the lower side of the rear limiting column 23 is connected to the fixing plate 44, the fixing plate 44 is in contact with the reset bucket 42, and three spirit levels 45 are provided on the fixing plate 44.

[0038] When the direction needs to be adjusted, not only the laser level 1 can be adjusted, but also the upper plate 21 can be controlled to rotate to achieve slight direction adjustment. The groove on the lower plate 22 cooperates with the limiting column 23 to limit the rotation angle of the upper plate 21 to avoid excessive rotation. The level 45 on the fixing plate 44 can detect the horizontal state of the upper plate 21, thereby ensuring the leveling state. After the laser level 1 is used, the central rod 25 will be controlled to rotate so that the nut 27 moves upward. The upward movement of the nut 27 will drive the lifting rod 41 to move upward, thereby driving the reset The bucket 42 moves upward, thereby correcting the fixed plate 44 and the limiting column 23, and then correcting the orientation of the upper plate 21. At the same time, it will also drive the handle 43 to move upward. At this time, the handle 43 will push the extrusion rod 36 to move upward, and the spring 37 will be compressed. At this time, the N-shaped structure of the extrusion rod 36 will no longer limit the separation arc plate 32. Then the spherical structure of the extrusion rod 36 will squeeze the separation arc plate 32 to rotate around the fixed column 31, so that the angle block 35 rotates and no longer jams the rotating cone foot 20. At this time, the laser level 1 can be easily removed.

[0039] like Figure 1 and Figure 8 As shown, a locking mechanism 5 is also included, which includes a square hole seat 51 and a lifting plate 52. The fixing seat 33 is connected to the square hole seat 51, and the lifting plate 52 is clamped on the square hole seat 51. The lifting plate 52 is in contact with the forked leg 24.

[0040] When the angle block 35 clamps the rotating cone foot 20, it can also pass through the lifting plate 52 to penetrate the square hole seat 51, and at the same time, the bottom of the lifting plate 52 is in contact with the forked leg 24 for support. At this time, the lifting plate 52 will limit and fix the angle block 35, thereby further ensuring the stability of the fixation.

[0041] like Figure 1 and Fig. 9 As shown, it also includes a horizontal mechanism 6, which includes a notch cover 61 and a weight handle 62. The front side of the laser level 1 is rotatably connected to the notch cover 61, and the lower side of the notch cover 61 is connected to the weight handle 62.

[0042] The notch protective cover 61 can protect the emission port of the laser level 1. At the same time, due to the gravity of the weight handle 62, the weight handle 62 is located directly below, so that the position of the emission port of the laser level 1 can be further detected through the notch protective cover 61, thereby ensuring the horizontal state of the laser level 1 and ensuring the accuracy of the test of the laser level 1.

[0043] like Figure 1 and Fig.10As shown, a fixing mechanism 7 is also included, and the fixing mechanism 7 includes an adjustment plate 71 and a fixing rod 72. The support feet 29 are all slidably connected to the adjustment plates 71, and the adjustment plates 71 are all threadedly connected to the fixing rods 72.

[0044] By adjusting the position of the adjusting plate 71, the fixing rod 72 can be controlled to rotate, so that the fixing rod 72 moves downward to be fixed, thereby further fixing the stabilizing device.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
