Description

Technical fields:

[0001] This utility model relates to the field of ground leveling technology, and more specifically to a multi-laser irradiation level measuring instrument. Background technology:

[0002] With social development and technological progress, it is often necessary to ensure the flatness of the ground at construction sites, stadiums, and sidewalks to guarantee safety during use and reduce road risks.

[0003] The surface smoothness of a road is usually determined by using a laser parallel to the ground. The laser emitter is placed on the ground, and the emitted laser is compared with the ground surface to observe whether the surface is smooth.

[0004] Existing traditional products can only emit two ground wires and cannot be rotated to change their angle as needed, thus limiting their applicability. Utility Model Content:

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-laser irradiation level measuring instrument. It can arbitrarily project three laser lines and rotate around the intersection point of the three laser lines as the axis to obtain a laser ground line with an arbitrary tilt angle. It can be used as a tool that combines laser line marking and plane tilt angle measurement, and has a wide range of applications.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A multi-laser irradiation level measuring instrument includes a main housing. The upper wall panel of the main housing has an upper emission through hole formed in the middle, and the left and right wall panels of the main housing have side emission through holes formed. A control main board and three laser emitters are installed inside the main housing. The three laser emitters are electrically connected to the control main board, and the laser beams of the laser emitters extend out of the corresponding upper emission through hole or side emission through hole.

[0008] The main housing includes a front housing and a rear fixed wall panel. The rear fixed wall panel covers the rear part of the front housing and is fixedly connected by bolts. A connecting post extending forward is formed in the middle of the front wall surface of the rear fixed wall panel. A central through hole is formed in the middle of the connecting post. The rear end of the central through hole extends out of the rear wall surface of the rear fixed wall panel. An upper central through hole is formed in the middle of the front wall panel of the front housing. The upper central through hole communicates with and corresponds to the central through hole of the connecting post.

[0009] Both the upper emission through-hole and the side emission through-hole are elongated through-holes extending from front to back;

[0010] The laser emitted from the side-emitting through-hole is perpendicular to the laser emitted from the top-emitting through-hole.

[0011] A permanent magnet block is fixed on the inner wall surface of the middle part of the rear fixed wall panel of the main housing. The fixed iron plate is located behind the rear fixed wall panel. A connecting shaft part extending forward is formed in the middle part of the front wall surface of the fixed iron plate. It is inserted into the rear end of the central through hole of the connecting column and cooperates with it. The front wall surface of the fixed iron plate presses against the rear wall surface of the rear fixed wall panel and is fixed by adsorption of the permanent magnet block.

[0012] The outstanding effect of this utility model is:

[0013] It can project three laser lines at will, and rotate around the intersection of the three laser lines as the axis to obtain a laser ground line with any tilt angle. It can be used as a tool that combines laser marking and plane tilt angle measurement, and has a wide range of applications.

[0014] It emits two laser lines on the left and right as ground lines, with a laser line perpendicular to them at the top. The two lines are on the same straight line and aligned with the bottom plane of the main housing. The center point where the three lines intersect is the central axis of the connecting column, which is connected to a fixed iron plate and serves as the rotational positioning axis of the main housing. The fixed iron plate can be fixed in the corresponding position, allowing the main housing to be rotated, thereby adjusting the tilt angle of the laser lines to obtain the required angle and meet different measurement needs.

[0036] In this embodiment, the inner cavity cover plate 15 can be opened to remove the nail head placed in the inner cavity, and then the inner cavity cover plate 15 can be closed again. The fixing iron plate 20 can be fixed in the required installation position by the nail head. Then, the main housing 10 can be manually rotated as needed. Since it is fixed by adsorption by a permanent magnet block, it can be fixed after being rotated into place, which is convenient for adjustment.

[0037] Furthermore, the main housing 10 and the fixed iron plate 20 are detachable structures. When the fixed iron plate 20 is not needed, the main housing 10 and the fixed iron plate 20 can be directly separated.
