Description

Technical Field

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

[0002] Ground-mounted laser line markers are widely used tools in construction, decoration, and other fields. They project bright, clear lines onto walls or floors, helping workers quickly and accurately position objects. They primarily rely on a laser as their light source. The light generated by the laser is optimized through a combination of lenses to ensure high collimation, ultimately forming a point or line light source.

[0003] In existing laser road markers, the internal mechanism components and the outer shell typically lack a mutually supporting structure. When the laser road marker falls and impacts the ground, the internal mechanism components may shift relative to the outer shell, causing a change in their relative positions and resulting in collisions. This can damage parts on the mechanism components or the outer shell, or the laser light source on the mechanism may be affected by vibration or impact, affecting the accuracy of the emitted laser line, indicating insufficient drop resistance. Furthermore, the laser fixing structure in existing laser road markers is relatively simple and lacks stability, further contributing to the overall insufficient drop resistance of existing laser road markers. Utility Model Content

[0004] The purpose of this invention is to provide a ground-level laser marking device that solves the technical problems of insufficient high-altitude working stability and inadequate drop resistance of existing laser marking devices.

[0005] This application discloses a ground-mounted laser marking device, including:

[0006] The outer casing has an internal cavity.

[0007] At least three uprights are vertically installed at intervals inside the outer casing;

[0008] A cross shaft assembly is installed on the top of the column;

[0009] A support plate is installed on the top of the cross shaft assembly, and the support plate has protruding sections around its perimeter and a clearance hole in the center of the support plate.

[0010] The movement is suspended below the cross shaft assembly;

[0011] Multiple lasers are installed at intervals on the mechanism, with the laser located at the top of the mechanism extending out of the clearance hole.

[0012] This application is equipped with a support plate, which can reduce the relative displacement between the internal movement components and the outer shell in the event of a drop or impact, thereby reducing the impact intensity and severity and ensuring the accuracy of the internal movement.

[0013] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0014] Furthermore, the protruding section extends toward the inner wall of the outer shell; a T-shaped reinforcing section is provided on the bottom side of the protruding section. The beneficial effect of this step is that the stability of the support plate can be ensured through the reinforcing section.

[0015] Furthermore, the laser is equipped with four first bolts and four second bolts. The diameter of the first bolts is larger than that of the second bolts, and the first bolts and the second bolts are evenly spaced and staggered. The advantage of this step is that by using multiple small bolts for pushing and multiple large bolts for pulling, the balanced pushing and pulling structure better ensures the stability of the laser fixation.

[0016] Furthermore, the cross shaft assembly includes:

[0017] An outer ring is installed on the top of the column, and the two opposite sides of the outer ring are arched, while the remaining two sides are provided with mounting holes;

[0018] The cross shaft has two ends set in the mounting holes, and the remaining two ends are installed on the top of the movement. The beneficial effect of this step is that the change of arched curvature provides elasticity, thereby improving the impact resistance.

[0019] Furthermore, the top of the arched side of the outer ring extends beyond the clearance hole;

[0020] A clamping section is provided on the inner side of the clearance hole. The clamping section is located on the outer ring. The beneficial effect of this step is that the clamping section can ensure the stability of the outer ring after assembly.

[0021] Furthermore, the support plate is made of metal or hard plastic. The advantage of this step is that it ensures the strength of the support plate, thereby ensuring the strength and stability of the support between the entire movement and the outer shell.

[0022] Furthermore, a weighted hammer is installed at the bottom of the mechanism, and the weight of the hammer is not less than 45g. The beneficial effect of this step is to reduce the amplitude, ensure the stability of the machine when operating at height, and avoid the impact of high-altitude shaking on the internal mechanism of the machine.

[0023] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0024] 1. This application is equipped with a support plate, which can reduce the offset between the outer shell and the movement when impacting the ground, thereby ensuring accuracy and facilitating user operation.

[0025] 2. This application designs the outer ring by providing an arched section, thereby achieving an elastic effect through the change in the arch's curvature, thus improving its impact resistance. Attached Figure Description

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] Example:

[0039] like Figure 1-2 As shown in the figure, this application discloses a ground-mounted laser marking device, which uses a support plate to connect the top of the column and the outer ring, ensuring the stability of the outer ring connection. At the same time, the support plate is a one-piece molded part, which can ensure the relative relationship between the columns, thereby ensuring stability and improving the drop resistance.

[0040] like Figure 1 As shown, the specific structure of this application includes:

[0041] The outer casing 1 has an internal cavity, and the outer casing 1 mainly serves a protective function to protect the components related to the movement.

[0042] At least three columns 2 are vertically installed at intervals inside the outer casing 1. These columns 2 are existing columns and mainly serve to provide support.

[0043] The cross shaft assembly 3 is installed on the top of the column 2. The cross shaft assembly 3 is mainly used to provide a suspension function. At the same time, this application also designs the cross shaft assembly 3 to adopt an arched outer ring structure, which can improve the impact resistance.

[0044] A support plate 4 is installed on the top of the cross shaft assembly 3, and the support plate 4 has protruding sections 401 around its perimeter. An avoidance hole 402 is provided in the middle of the support plate 4. In this application, the support plate 4 is installed on the top of the column 2. The support plate 4 is preferably made of a high-hardness material, which can ensure the strength and stability of the support between the entire movement and the outer shell. At the same time, this application also provides protruding sections 401, which extend outward and closely approach the inner wall of the outer shell 1 to form a support, reducing the relative positional displacement of the outer shell and the movement during impact. That is, when this application is dropped or impacted, it effectively avoids the relative displacement between the movement and the cross shaft assembly 3 and the outer shell, reduces the impact intensity and severity, and thus ensures the integrity of the internal components and the precision of the movement.

[0045] The mechanism 5 is suspended below the cross shaft assembly 3. The mechanism 5 is an existing mechanism, which is subsequently connected to a related laser 6 to realize the function of emitting laser lines.

[0046] Multiple lasers 6 are installed at intervals on the core 5. The laser 6 located at the top of the core 5 extends out of the clearance hole 402, which is designed to facilitate the extension of other components.

[0047] like Figure 2 As shown, the following further describes the support plate 4, which is an integrally molded part. The protruding section 401 is closely close to the inner wall of the outer shell 1, that is, the protruding section extends toward the inner wall of the outer shell. A T-shaped reinforcing section 403 is provided on the bottom side of the protruding section 401. The close proximity of the protruding section 401 can reduce material and weight. At the same time, the T-shaped reinforcing section 403 at the bottom can further enhance the strength of the protruding section 401, thereby ensuring the strength and stability of the overall structure.

[0048] To ensure the stability of the laser installation, this application designs the specific assembly of the laser 6, wherein the laser 6 is equipped with four first bolts 8 and four second bolts 9. The diameter of the first bolts 8 is larger than the diameter of the second bolts 9, and the first bolts 8 and the second bolts 9 are evenly spaced and staggered. Specifically, the bolts are installed from the end of the laser 6 and then evenly spaced and staggered. They are tightened by the four large bolts, and the ends of the four small bolts press against the assembly surface of the laser and the core 5, thereby forming a four-pull and four-top-pull structure to ensure the stability of the structure.

[0049] Further design is made for cross shaft assembly 3, which includes:

[0050] The outer ring 301 is installed on the top of the column 2, and the two opposite sides of the outer ring 301 are arched, while the remaining two sides are provided with mounting holes 302.

[0051] A cross shaft 303 is provided at both ends in the mounting holes 302, and the remaining two ends are installed on the top of the movement 5. The cross shaft 303 and the outer ring 301 cooperate with each other to realize the function of suspending the movement 5. At the same time, the outer ring 301 in this application has two opposite sides that are arched. Through the change of the arched curvature, it plays an elastic role, thereby improving the impact resistance.

[0052] Specifically, during actual assembly, the top of the arched side of the outer ring 301 extends out of the clearance hole 402, thus forming sufficient assembly space. At the same time, the other planar sections of the outer ring 301 cooperate with the support plate 4, making the connection more stable.

[0053] A clamping section 404 is provided on the inner side of the clearance hole 402. The clamping section 404 is located on the outer ring 301 and is arc-shaped, mainly to further ensure stability.

[0054] In this application, the support plate 4 is made of metal or rigid plastic to ensure strength.

[0055] Specifically, a weight 7 is installed at the bottom of the mechanism 5. The weight of the weight 7 is not less than 45g. The large weight can significantly reduce the swing amplitude of the mechanism, better ensure the machine can be quickly and stably stabilized during high-altitude operations, avoid the impact of high-altitude shaking on the internal mechanism, and improve the work efficiency of the user.

[0056] Further explanation is provided regarding this application:

[0057] 1. Regarding the outer ring, this application designs the two opposite sides of the outer ring as arches, thereby achieving an elastic effect through the change of the arch's curvature, thus improving the overall impact resistance of the laser marking instrument.

[0058] 2. This application includes a support plate, an integrally molded part, to abut against the inner wall of the outer shell, thereby reducing the displacement of the movement part and the outer shell, thus reducing the impact intensity and severity and protecting the machine's precision.
