Description

Technical Field

[0001] This utility model relates to the field of laser instruments, specifically to a laser level pendulum based on an integrated optical mirror. Background Technology

[0002] A laser level accurately projects horizontal, vertical, or crosshairs outward through a laser module. Its core component is a pendulum, which is used to mount the laser module. The pendulum maintains its orientation through its own weight, allowing the laser module to project horizontal and vertical laser lines through optical mirrors in two directions.

[0003] In existing level pendulum systems, the optical mirror is typically mounted on the laser module, such as... Figure 4 The existing pendulum shown requires fine-tuning of the laser module's position and angle using adjusting bolts during assembly, so that the laser lines formed by the two optical mirrors are oriented vertically and horizontally respectively when the pendulum is in a stable position. The adjustment process is cumbersome and the accuracy is difficult to guarantee. Utility Model Content

[0004] The purpose of this invention is to provide a laser level pendulum based on an integrated optical mirror, which solves the problem of high debugging difficulty of existing laser modules.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A laser level pendulum based on integrated optical mirrors includes a pendulum body and a laser module assembled on the pendulum body. The pendulum body is provided with a mounting part, and at least two optical mirrors are mounted on the mounting part. The at least two optical mirrors are used to convert the laser beam emitted by the laser module into laser lines in different directions.

[0007] As a preferred embodiment of this utility model, the mounting part is located on the side of the pendulum body and is integrally formed with the pendulum body, so that the optical mirror can keep the orientation of the pendulum body synchronized after installation, eliminating the problem of adjusting the orientation of the optical mirror.

[0008] As a preferred embodiment of this utility model, the mounting part is a protruding structure with a snap-fit ​​groove on its surface, and the snap-fit ​​groove is uniquely guided to the optical mirror. In this way, the angle of the optical mirror is synchronized with the pendulum body, and the balance position of the pendulum body can be adjusted during debugging.

[0009] As a preferred embodiment of this utility model, the pendulum body has a groove, the laser module is assembled in the groove, and a connecting hole for the laser beam to pass through is provided between the groove and the snap-fit ​​groove.

[0010] As a preferred embodiment of this utility model, the laser module includes a housing and a laser generator, and the housing is provided with a flange for debugging and installation with the pendulum body.

[0011] As a preferred embodiment of this utility model, the flange is provided with at least three mounting holes, and the pendulum body is provided with threaded holes corresponding to the mounting holes.

[0012] As a preferred embodiment of this utility model, the housing is provided with a threaded groove for assembling a laser generator, and the end of the housing is provided with a collimating lens and a threaded cap for assembling the collimating lens. The collimating lens is a prior art technology used to align the laser beam emitted by the laser diode.

[0013] As a preferred embodiment of this utility model, the optical mirror has two parts, and the two optical mirrors are used to convert the laser beam of the laser module into a horizontal laser line and a vertical laser line, respectively.

[0015] As a preferred embodiment of this utility model, the pendulum body is provided with at least two center of gravity adjustment bolts in two directions, which are used to adjust the center of gravity of the pendulum body and solve the problem that the center of gravity of the pendulum body does not reach a stable position due to the assembly of the laser module.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1-3 As shown, a laser level pendulum based on an integrated optical mirror includes a pendulum body 1 and a laser module 3 assembled on the pendulum body 1. The pendulum body 1 is provided with a mounting part 101, and at least two optical mirrors 2 are mounted on the mounting part. The at least two optical mirrors 2 are used to convert the laser beam emitted by the laser module 3 into laser lines in different directions.

[0026] This solution integrates two optical mirrors 2 in one mounting part 101 and assembles them directly with the pendulum body 1, so that the orientation of the optical mirrors 2 is directly synchronized with the pendulum body 1. There is no need to precisely adjust the orientation of the optical mirrors 2 during assembly. The laser module 3 is assembled inside the pendulum body 1 and faces the optical mirrors 2. It is only necessary to adjust the emitted laser beam to be aligned with the two optical mirrors 2 so that a laser line can be formed on the other side of the optical mirrors 2. This eliminates the need to adjust the orientation of the optical mirrors 2 and greatly reduces the difficulty of adjustment.

[0027] Please see Figure 1 In this embodiment, the mounting part 101 is located on the side of the pendulum body 1 and is integrally formed with the pendulum body 1 so that the optical mirror 2 can keep the orientation of the pendulum body 1 synchronized after installation, eliminating the problem of adjusting the orientation of the optical mirror 2.

[0028] Preferably, the mounting part 101 is a protruding structure with a snap-fit ​​groove 102 on its surface, and the snap-fit ​​groove 102 provides a unique guide for the optical mirror 2. The snap-fit ​​groove 102 facilitates the installation of the optical mirror 2. The protrusion of the mounting part 101 can be a cylindrical protrusion, a square protrusion, or a protrusion of other shapes, and the snap-fit ​​groove 102 provides a unique guide for the optical mirror 2. In this way, the angle of the optical mirror 2 is synchronized with the pendulum body 1. During adjustment, the balance position of the pendulum body 1 can be adjusted. As another alternative, the shape of the snap-fit ​​groove 102 can be set to match the shape of the optical mirror 2, such as square or cylindrical.

[0029] Preferably, the pendulum body 1 has a groove 105, the laser module 3 is assembled in the groove 105, and a connecting hole 103 for the laser beam to pass through is provided between the groove 105 and the snap-fit ​​groove 102. The groove 105 is used to assemble the laser module 3. It is only necessary to make the laser module 3 face the optical mirror 2, which greatly reduces the difficulty of debugging.

[0030] Furthermore, the laser module 3 includes a housing 301 and a laser generator 307. The housing 301 is provided with a flange 302 for installation and adjustment with the pendulum body 1. Specifically, the flange 302 is provided with at least three mounting holes 306, and the pendulum body 1 is provided with threaded holes corresponding to the mounting holes 306. The connection between the flange 302 and the housing 301 is chamfered for contacting and adjusting the angle of the laser module 3 with the pendulum body 1. In this embodiment, the flange 302 and the mounting holes 306 are used for positioning. When the chamfer contacts the groove 105, a bolt passes through the mounting hole 306 and enters the threaded hole. With different degrees of bolt screwing, the distance between different parts of the flange 302 and the groove 105 is different, presenting different angles. This allows for fine-tuning of the angle, aligning the laser module 3 with the optical mirror 2. After correction, it is encapsulated with glue to prevent subsequent shaking. It should be noted that the inner diameter of the mounting hole 306 needs to be larger than the bolt body.

[0031] In addition, the housing 301 is provided with a threaded groove 303 for assembling the laser generator 307, and the end of the housing 301 is provided with a collimating lens 305 and a threaded cap 304 for assembling the collimating lens 305. The laser generator 307 uses a laser diode. After the laser emitted by the laser diode is rectified by the collimating lens 305, the beam is positioned by the flange 302 so that the beam is directed toward the optical mirror 2, and a laser line can be formed on the other side of the optical mirror 2.

[0032] Preferably, there are two optical mirrors 2, and the two optical mirrors 2 are used to convert the laser beam of the laser module 3 into a horizontal laser line and a vertical laser line, respectively. In this embodiment, the two optical mirrors 2 are integrated on a mounting part 101 and arranged in a T-shape in the slot 102. The horizontal laser beam and the vertical laser beam are the most common and most demanded laser beam directions. In addition, when carrying out slope construction, an angled laser line may also be required, and the angle between the two optical mirrors 2 needs to meet the construction requirements. For example, one optical mirror 2 is vertical or horizontal, and the other optical mirror 2 has an angle of 30°, 45° or 60° with the vertical / horizontal line.

[0033] As a preferred option, please refer to Figure 1 To facilitate the installation of the pendulum body 1 and the laser device, the upper end of the pendulum body 1 is also provided with a hinge ear 104 and a pendulum shaft assembly 4. The pendulum shaft assembly 4 has a first shaft 401 and a second shaft 402. The first shaft 401 and the second shaft 402 are both horizontally arranged and perpendicular to each other, and the vertical plane where the axis is located coincides with the center of gravity of the pendulum body 1. By setting the first shaft 401 and the second shaft 402, the pendulum body 1 maintains the required orientation under its own weight. The first shaft 401 is connected to the hinge ear 104, while the second shaft 402 is used to connect to the external frame.

[0034] As a further preferred embodiment, since the assembly of the laser module 3 may cause the center of gravity of the pendulum body 1 to not reach a stable position, resulting in the optical mirror 2 on the pendulum body 1 being misaligned, in this embodiment, at least two center of gravity adjustment bolts 106 in two directions are provided on the pendulum body 1 to adjust the center of gravity of the pendulum body 1. After the laser module 3 is assembled, the center of gravity of the pendulum body 1 is made to be located on the vertical plane where the axis of the aforementioned shaft is located by the center of gravity adjustment bolts 106. Preferably, the center of gravity adjustment bolts 106 can be two sets of bolts, and the directions of the two sets of bolts are perpendicular to each other.

[0035] Preferably, the optical lens 2 can be a cylindrical lens or a Powell prism, and the locking slot 102 adopts a corresponding shape to fix the optical lens 2.

[0036] Detailed implementation method: When assembling the pendulum body of this laser level, first install the optical mirror 2 into the snap-fit ​​slot 102, then position and install the laser module 3 so that the beam emitted by it is directed toward the optical mirror 2 and can form a laser line on the other side of the optical mirror 2. Then, adjust the center of gravity of the pendulum body 1 by adjusting the center of gravity bolt 106, and then install the pendulum body into the laser level by using the pendulum shaft assembly 4.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
