Description

Technical Field

[0001] The utility model belongs to the technical field of laser level instruments, and particularly relates to an automatic leveling laser level instrument. Background Technique

[0002] Laser level instrument: An instrument that projects a visible laser beam and can level and position heights according to the laser beam. Another concept is an instrument that makes the visible laser point (generally red and green) sweep out a light beam at the same level height driven by a rapidly rotating shaft, facilitating engineering personnel to position the level height.

[0003] Chinese Patent Publication No.: 2005200784477 discloses an automatic leveling laser level instrument. When the original laser level instrument is not in use, it does not have a function to protect the reflecting mirror. The reflecting mirror is easily scratched when it touches sharp objects. At the same time, dust and other impurities are likely to accumulate on the surface of the reflecting mirror, affecting the subsequent reflection quality of the laser by the reflecting mirror. Moreover, the original laser level instrument uses a hook to hang the laser level instrument on the supporting component, and the safety is relatively low. When the hook is separated from the supporting component, the laser level instrument is likely to fall and cause damage. Content of the Utility Model

[0004] To solve the problems raised in the above background technique, the utility model provides an automatic leveling laser level instrument, which has the characteristics of being able to protect the reflecting mirror, the reflecting mirror is not easily damaged, and dust and other impurities are not easily attached to the surface of the reflecting mirror.

[0005] To achieve the above object, the utility model provides the following technical solution: An automatic leveling laser level instrument includes a box body. A plumb bob is arranged at the lower end of the box body. A top plate is arranged on the upper side of the box body. The top plate and the box body are connected by a plurality of connecting columns. A reflecting mirror is arranged at the middle position of the lower end of the top plate. A semiconductor laser is arranged at the position corresponding to the reflecting mirror at the upper end of the box body. A hook is arranged at the middle position of the upper end of the top plate. A connecting cylinder is arranged below the reflecting mirror. A conical cylinder is arranged at the lower end of the connecting cylinder. A protrusion is arranged at the upper end of the connecting cylinder. An installation groove corresponding to the protrusion is opened at the lower end of the top plate. A first thread is arranged on the surface of the protrusion, and a second thread corresponding to the first thread is arranged on the inner wall of the installation groove.

[0006] Preferably, the conical cylinder and the connecting cylinder are connected by spot welding, and both the connecting cylinder and the conical cylinder are made of aluminum structures.

[0007] Preferably, a rubber pad is adhesively arranged at the upper end of the connecting cylinder, and the depth of the installation groove is the same as the height of the protrusion.

[0008] Preferably, fixing plates are arranged at both ends of the upper side of the surface of the hook. A locking rod is arranged between the two fixing plates. A torsion spring is arranged between the locking rod and the hook.

[0009] Preferably, one end of the locking rod is provided with a groove corresponding to the hook, and the locking rod is configured as a stainless steel structure.

[0010] Preferably, the locking rod and the fixing plate are rotationally connected via an axle pin, and the torsion spring and the locking rod as well as the torsion spring and the hook are connected via snap connections.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model sets a conical tube. When the equipment is not in use, the protrusion on the upper end of the connecting tube is rotated into the installation groove through the first and second threads, so as to achieve the effect of fixing the lower connecting tube and the conical tube.

[0024] Specifically, the tapered cylinder 9 and the connecting cylinder 8 are connected by spot welding, and both the connecting cylinder 8 and the tapered cylinder 9 are made of aluminum structures.

[0025] By adopting the above technical solutions, the connection between the tapered cylinder 9 and the connecting cylinder 8 is made more firm, and the aluminum structure is lighter and more convenient to use.

[0026] Specifically, a rubber pad is adhesively provided at the upper end of the connecting cylinder 8 by glue, and the depth of the installation groove 11 is the same as the height of the protrusion 12.

[0027] By adopting the above technical solutions, the protrusion 12 is more fitting when installed in the installation groove 11, and the rubber pad plays an anti-slip effect to prevent the protrusion 12 from falling off.

[0028] When this embodiment is in use, when the device is not in use, the protrusion 12 at the upper end of the connecting cylinder 8 is rotated into the installation groove 11 through the first thread 13 and the second thread 17, so as to fix the lower connecting cylinder 8 and the tapered cylinder 9. The connecting cylinder 8 and the tapered cylinder 9 can protect the reflecting mirror 10, prevent the reflecting mirror 10 from being scratched by touching sharp objects, and at the same time prevent dust and other impurities from accumulating on the surface of the reflecting mirror 10, affecting the subsequent reflection quality of the reflecting mirror 10 for the laser;

[0029] Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that fixing plates 14 are provided at both upper ends of the surface of the hook 4, a locking rod 5 is provided between the two fixing plates 14, and a torsion spring 15 is provided between the locking rod 5 and the hook 4.

[0031] By adopting the above technical solution, the locking rod 5 is toggled to rotate on the fixing plate 14, and at the same time the torsion spring 15 is compressed. After connecting the hook 4 with the support member, the locking rod 5 is released, and the torsion spring 15 rebounds to drive the locking rod 5 to reset, so as to achieve the effect of locking the hook 4, making it not easy to fall off between the hook 4 and the support member, and the safety is higher.

[0032] Specifically, a slot 16 corresponding to the hook 4 is opened at one end of the locking rod 5, and the locking rod 5 is made of stainless steel structure.

[0033] By adopting the above technical solution, a slot 16 corresponding to the hook 4 is opened on the locking rod 5, so that the locking rod 5 and the hook 4 are more closely attached, and the locking effect is better. The locking rod 5 made of stainless steel structure is more solid and not easy to be damaged.

[0036] When this embodiment is used, by arranging the locking rod 5 in the hook 4, when connecting the hook 4 with the support member, the locking rod 5 is toggled to rotate on the fixing plate 14, and at the same time the torsion spring 15 is compressed. After connecting the hook 4 with the support member, the locking rod 5 is released, and the torsion spring 15 rebounds to drive the locking rod 5 to reset, so as to achieve the effect of locking the hook 4, making it not easy to fall off between the hook 4 and the support member, and the safety is higher. At the same time, a slot 16 corresponding to the hook 4 is opened on the locking rod 5, so that the locking rod 5 and the hook 4 are more closely attached, and the locking effect is better.

[0037] The structures and working principles of the box body 1, the connecting column 2, the top plate 3, the hook 4, the semiconductor laser 6, the plumb bob 7 and the mirror 10 in this utility model have been disclosed in an automatic leveling laser level disclosed in Chinese Patent Publication No.: 2005200784477.

[0038] Working principle and usage process of the present utility model: When the present utility model is in use, the device is installed at a suitable position, and the equipment is connected to the support member through the hook 4. The plumb bob 7 is perpendicular to the natural horizontal plane under the action of gravity, and the semiconductor laser 6 emits laser light, which is reflected by the mirror 10 to make the laser plane parallel to the natural horizontal plane. By setting the conical cylinder 9, when the equipment is not in use, the protrusion 12 at the upper end of the connecting cylinder 8 is rotated into the installation groove 11 through the thread one 13 and the thread two 17, achieving the effect of fixing the lower connecting cylinder 8 and the conical cylinder 9. The connecting cylinder 8 and the conical cylinder 9 can protect the mirror 10, preventing the mirror 10 from being scratched by touching sharp objects, and at the same time preventing impurities such as dust from accumulating on the surface of the mirror 10 and affecting the subsequent reflection quality of the mirror 10 for the laser. By setting the locking rod 5 in the hook 4, when connecting the hook 4 with the support member, the locking rod 5 is toggled to rotate on the fixed plate 14, and at the same time the torsion spring 15 is compressed. After connecting the hook 4 with the support member, the locking rod 5 is released, and the torsion spring 15 rebounds to drive the locking rod 5 to reset, thus achieving the effect of locking the hook 4, making it not easy to fall off between the hook 4 and the support member, with higher safety. At the same time, a slot 16 corresponding to the hook 4 is opened on the locking rod 5 to make the locking rod 5 fit better with the hook 4 and the locking effect is better.
