Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, and in particular to a wall-mounted laser marking instrument. Background Technology

[0002] A laser line marker is a measuring instrument that uses laser technology to accurately mark lines. It is widely used in construction and decoration work for marking lines on walls, floors, ceilings, doors, windows, and other locations. The working principle of a laser line marker is based on the reflection and focusing of a laser beam. When the laser beam is reflected on a mirror, the direction of the beam can be changed. By adjusting the angle of the mirror, the direction and position of the laser beam can be changed to facilitate measurement.

[0003] The laser in existing laser line markers is usually installed in the middle of the mechanism, which makes the center of gravity of the mechanism in the middle or lower position, away from the cross axis. As a result, when the mechanism is hit during use, it swings a lot, which affects subsequent calibration. Moreover, the existing weight mechanism is usually a single weight, which has low braking efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a wall-mounted laser marking device that solves the technical problem of large sway caused by the low center of gravity of the mechanism in existing laser marking devices, which affects subsequent leveling.

[0005] This application discloses a wall-mounted laser marking device, comprising:

[0006] The outer casing has an internal cavity.

[0007] The movement is installed inside the housing, and the top of the movement is provided with an assembly cavity;

[0008] The inner ring is installed inside the assembly cavity;

[0009] A cross shaft is installed inside the assembly cavity. Two opposite ends of the cross shaft are connected to the inner ring, and the remaining two opposite ends of the cross shaft are connected to the inner wall of the assembly cavity.

[0010] Multiple lasers are installed at intervals on the outer wall of the assembly cavity;

[0011] A column assembly is installed inside the housing, and the top of the column assembly is connected to the top of the movement.

[0012] The counterweight assembly is mounted at the bottom of the movement.

[0013] This application designs the movement and adjusts the position of the laser to be closer to the cross axis, thereby reducing oscillation.

[0014] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0015] Furthermore, the column assembly includes:

[0016] Multiple columns are installed at intervals inside the outer casing;

[0017] A connecting plate is installed on the top of the column, and the bottom of the connecting plate is connected to the top of the movement. The advantage of this step is that the stability of the movement can be guaranteed by the cooperation of multiple columns and connecting plates.

[0018] Furthermore, the counterweight assembly includes:

[0019] A counterweight component, the middle part of which is mounted on the bottom of the mechanism;

[0020] A magnetic disc is installed at the bottom of the outer casing, and the magnetic disc cooperates with the counterweight. The beneficial effect of this step is that braking can be achieved through the cooperation of the magnetic disc and the counterweight.

[0021] Furthermore, the magnet disc consists of two pieces, and the magnet discs are located on both sides of the mechanism. The advantage of this step is that it facilitates the formation of a double hammer structure, thereby improving the braking effect.

[0022] Furthermore, the upper surface of the magnet disk is an inclined plane, and the counterweight is an upwardly curved arc. The beneficial effect of this step is that it can better form braking, thereby achieving rapid leveling.

[0023] Furthermore, a counterweight is provided on the outer side of the movement. The beneficial effect of this step is that the counterweight can better ensure the stability of the movement.

[0024] Furthermore, the center of the laser is located on the same horizontal plane. The advantage of this step is that the position of the laser is designed to facilitate better adjustment of the center of gravity of the mechanism.

[0025] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0026] 1. This application designs the movement by installing a laser on the top of the movement, making the laser closer to the cross axis, thereby raising the overall center of gravity of the movement, reducing the amplitude of swaying during subsequent impacts, and facilitating quick leveling.

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0037] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0040] Example:

[0041] like Figure 1-3 As shown in the figure, this application discloses a wall-mounted laser line marker. The installation position of the laser in the laser line marker is designed to be closer to the top of the mechanism, that is, closer to the cross shaft. This not only allows it to fit closer to the wall, but also further ensures stability. This application also designs the weighted part, adopting a structure similar to a double hammer. After impact, the mechanism can be stabilized more quickly, thereby improving the stability of the laser line marker.

[0042] like Figure 1 , 3 As shown, the specific structure of this application includes:

[0043] The outer shell 1 has an internal cavity 101. The outer shell 1 is a shell component, and its internal cavity is for the subsequent installation of related components.

[0044] The mechanism 2 is installed inside the outer casing 1, and the top of the mechanism 2 is provided with an assembly cavity 201. Further explanation of the mechanism 2: the mechanism 2 is divided into at least two sections, a lower cylindrical section and an upper recessed section. The recessed section is used to assemble the cross shaft inside and to mount the laser outside. Compared to existing laser mounting positions, the laser in this application is closer to the cross shaft, which effectively raises the position of the laser, i.e., the overall center of gravity, thereby reducing swaying and facilitating rapid recovery of the laser marker after impact.

[0045] Inner ring 3 is installed inside the assembly cavity 201. This inner ring 3 is used to install the cross shaft to facilitate subsequent installation.

[0046] A cross shaft 4 is installed inside the assembly cavity 201. Two opposite ends of the cross shaft 4 are connected to the inner ring 3, and the remaining two opposite ends of the cross shaft 4 are connected to the inner wall of the assembly cavity 201. The cross shaft 4 is an existing mechanism and will not be described in detail here.

[0047] Multiple lasers 5 are installed at intervals on the outer wall of the assembly cavity 201. The lasers 5 can also be longer lasers, so that the head of the laser is close to the viewing window, thus getting closer to the wall.

[0048] The column assembly 6 is installed inside the housing, and the top of the column assembly 6 is connected to the top of the movement 2. The column assembly 6 is used to install the movement and ensure that it is stably located inside the housing 1.

[0049] The counterweight assembly 7 is installed at the bottom of the movement 2. The counterweight assembly 7 can achieve braking, thereby enabling the movement to stabilize quickly and thus improving working efficiency.

[0050] To further explain this application, the installation position of the laser 5 is designed to be at the top of the mechanism 2, thus being closer to the cross axis, thereby increasing the height of the overall center of gravity and reducing the swing amplitude.

[0051] In one embodiment, such as Figure 2 As shown, the column assembly 6 includes:

[0052] Multiple columns 601 are installed at intervals inside the outer casing 1. There are multiple columns 601, which are arranged vertically.

[0053] A connecting plate 602 is installed on the top of the column 601, and the bottom of the connecting plate 602 is connected to the top of the movement 2. In this application, the movement 2 is installed by the column 601 cooperating with the connecting plate 602.

[0054] The counterweight assembly 7 includes:

[0055] A counterweight 701, the middle part of which is installed at the bottom of the mechanism 2;

[0056] A magnetic disc 702 is installed at the bottom of the outer casing 1, and the magnetic disc 702 cooperates with the counterweight 701. After impact, the counterweight 701 swings with the movement and is braked by the magnetic disc 702, so that the movement can stop quickly.

[0057] The counterweight in this application has a double-hammer structure, that is, the magnetic disk 702 in this application consists of two pieces, and the magnetic disk 702 is located on both sides of the mechanism 2. In this way, when the counterweight swings back and forth with the mechanism 2, it can be braked quickly, thereby achieving leveling.

[0058] Specifically, the upper surface of the magnet disk 702 in this application is an inclined plane, and the counterweight 701 is an upwardly curved arc-shaped component. This allows the movement to be doubled in braking during swinging, thereby stopping quickly.

[0059] In one embodiment, a counterweight 8 is provided on the outer side of the mechanism 2 to balance the weight of the laser, thereby ensuring the stability of the mechanism.

[0060] Specifically, the center of the laser 5 is located on the same horizontal plane, which ensures that the center of gravity of the entire mechanism is in a higher position, thereby reducing swaying and achieving rapid leveling.

[0061] To further explain this application, the position of the laser is adjusted so that the center of gravity of the entire mechanism is in a higher position, closer to the cross axis, thereby reducing swaying and improving the efficiency of recovery after impact.

[0062] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details.
