Description

Technical Field

[0001] This invention relates to the field of measuring tool technology, and more specifically to a laser adjustment mechanism and a laser-adjustable level including the mechanism. Background Technology

[0002] A spirit level is a common measuring tool in construction, decoration, and other fields, used to check whether a surface is level or vertical. Traditional spirit levels rely on observing the position of a bubble, which is difficult to read and has limited accuracy in situations involving long distances, long spans, or poor lighting. Some existing laser spirit levels typically have a fixed laser emission direction (e.g., only horizontal or only vertical), which cannot meet users' flexible needs for a compact structure and multi-angle laser projection. Therefore, a mechanism is needed that is compact, easy to adjust, and can precisely change the laser projection angle. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a laser adjustment mechanism that is compact, easy to adjust, and capable of continuous or segmented adjustment of the laser projection angle, as well as a laser adjustable level containing the mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a laser adjustment mechanism, including a housing, a rotating component disposed inside the housing, a laser generator disposed inside the rotating component, the laser generator being configured to rotate with the rotating component and adjust the angle formed between the laser direction and the length direction of the housing, and a light-transmitting part disposed on the housing, the light-transmitting part being configured to allow the laser to be emitted from the light-transmitting part.

[0005] The present invention further provides that the rotation angle range of the rotating component is [0°, 90°]. This allows the laser direction to be continuously or segmentally adjusted from a direction parallel to the housing to a direction perpendicular to the housing, satisfying various angle projection requirements. The invention further includes an operating part located outside the housing and a main body located inside the housing. The operating part drives the main body to rotate synchronously. A mounting cavity is formed within the main body, and the laser generator is located within the mounting cavity with its light-emitting part facing the light-transmitting part. An opening is formed on the main body within the mounting cavity, and the openings are opposite to each other. The light-emitting part is located in the opening near the light-transmitting part. This structure achieves internal and external linkage, facilitates operation, and ensures stable installation of the laser generator and clear optical path direction.

[0006] The invention further includes a housing comprising a cover and a base, the cover and the base being fixedly connected. A sealing groove is formed on the inner side of the cover, and a sealing ring is disposed within the sealing groove. This structure facilitates assembly and maintenance, while the sealing ring effectively prevents dust, moisture, and other contaminants from entering the housing, thus improving product lifespan and reliability.

[0007] In a further embodiment of the invention, a fixing clamp is provided on the side of the main body near the operating part. The sealing gasket is located between the fixing clamp and the sealing ring. The fixing clamp, sealing gasket, and sealing ring work together to restrict the axial movement of the rotating part, ensuring smooth rotation, and to enhance the sealing effect.

[0008] The invention further includes an operating part located outside the cover, with the main body situated within the internal space formed between the cover and the base. An indicator disc is formed on the side of the operating part closest to the cover, and a scale area is formed on the cover. The indicator disc, in conjunction with the scale area, indicates the angle between the current laser direction and the length direction of the housing. This design makes angle adjustment visual, allowing the user to precisely set the desired laser projection angle.

[0009] In a further embodiment of the invention, the light-transmitting portion is a curved plate structure made of transparent material, which engages with the locking grooves formed on the cover and the base. The curved plate structure can cooperate with rotating components to provide unobstructed light emission channels for lasers at different angles.

[0010] The invention further specifies that the curved plate structure is a quarter-circle arc plate. This shape perfectly matches the laser angle adjustment range of 0° to 90°, resulting in a reasonable structure and a smooth appearance.

[0011] Secondly, the present invention provides a laser-adjustable level, including a level body and a laser adjustment mechanism as described above disposed at at least one end of the level body, wherein the housing is provided with a connecting part connected to the level body.

[0012] This invention offers at least one of the following advantages: By incorporating a rotatable rotating component to house the laser generator, the invention achieves flexible and continuous adjustment of the laser projection angle relative to the housing, resulting in a compact structure and easy operation. The coordination of the operating unit, indicator dial, and scale area enables precise and visual angle adjustment, improving measurement accuracy and user experience. The housing adopts a split design of the cover and base, and incorporates multiple sealing structures such as sealing rings and gaskets, effectively enhancing the product's dustproof and waterproof performance and overall reliability. The light-transmitting part uses an arc-shaped curved plate design, ensuring smooth laser emission at all adjustment angles while also protecting the internal structure. Applying this laser adjustment mechanism to a spirit level greatly expands its functionality, enabling it not only to perform traditional horizontal / vertical measurements but also to project laser reference lines at any desired angle, making it suitable for more complex construction scenarios.

[0019] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] In traditional laser levels, the fixed laser emission direction prevents flexible adjustment of the projection angle, limiting measurement accuracy and causing inconvenience in scenarios involving long distances, long spans, or poor lighting. This problem stems from the structural design of existing laser levels, where the laser generator is fixedly connected to the housing, lacking an angle adjustment mechanism. This restricts multi-angle measurement capabilities; specifically, the angle between the laser direction and the length direction of the housing is fixed, making it unsuitable for various measurement needs.

[0021] For example, when conducting horizontal inspections of long-span walls at construction sites, insufficient lighting and long measurement distances necessitate operators to simultaneously inspect both horizontal and vertical surfaces. However, existing laser levels can only emit laser light in a single direction, making it impossible to adjust the laser angle without changing the equipment. This necessitates frequent tool switching or manual adjustments, increasing operational complexity and reducing measurement efficiency. In this scenario, the fixed laser direction directly manifests as the inability to simultaneously meet the projection requirements of both horizontal and vertical surfaces, forcing the measurement process to rely on additional auxiliary methods and thus affecting the overall workflow's continuity.

[0022] If the aforementioned problems are not addressed, the application scope of laser levels will be significantly limited, especially in complex architectural environments where multi-angle measurement needs cannot be met. This will lead to decreased reliability in the measurement process, increased risk of human error, and hinder the widespread application of this tool in diverse scenarios. Furthermore, limitations in structural design will continue to restrict the adaptability of the equipment, making it difficult to achieve precise laser projection control under dynamic measurement conditions, thus negatively impacting the accuracy of measurement results. This invention includes at least one of the following beneficial effects: By incorporating a rotatable rotating component to house the laser generator, this invention achieves flexible and continuous adjustment of the laser projection angle relative to the housing, resulting in a compact structure and easy operation. Through the cooperation of the operating section, indicator dial, and scale area, precise and visual angle adjustment is achieved, improving measurement accuracy and user experience. The housing adopts a split design of the cover and base, and incorporates multiple sealing structures such as sealing rings and gaskets, effectively improving the product's dustproof and waterproof performance and overall reliability. The light-transmitting part adopts an arc-shaped curved plate design, ensuring smooth laser emission at all adjusted angles while also protecting the internal structure. Applying the aforementioned laser adjustment mechanism to a spirit level greatly expands its functionality, enabling it not only to perform traditional horizontal / vertical checks but also to project laser baselines at any desired angle, making it suitable for more complex construction scenarios. Example

[0023] To address this issue, this application proposes a laser adjustment mechanism, including a housing 10. A rotating component 20 is housed within the housing 10, and a laser generator is housed within the rotating component 20. The laser generator is configured to rotate with the rotating component 20 and adjust the angle between the laser direction and the length direction of the housing 10. A light-transmitting portion 30 is also provided on the housing 10, configured to allow laser light to be emitted. The housing 10 serves as an integral support frame, ensuring a compact structure. The rotating component 20 provides rotational movement capability. The laser generator rotates synchronously with the rotating component 20, directly changing the angle between the laser direction and the length direction of the housing 10. The light-transmitting portion 30 allows laser emission while protecting internal components. Thus, the laser generator adjusts its angle as the rotating component 20 rotates, achieving flexibility and precision in multi-angle laser projection. Specifically, this configuration, through the integrated structural design of the rotating component 20 and the laser generator, overcomes the technical obstacle of fixing the laser direction, enabling the fulfillment of different angle laser projection requirements within a single device. In a preferred embodiment, the position of the light-transmitting part 30 is configured to correspond to the laser path to ensure that the laser is emitted without obstruction.

[0024] For ease of understanding, the following explains some key terms in this embodiment: Housing 10: Serving as the external support and protective structure for the laser adjustment mechanism, its internal space is used to house and secure other components, ensuring the integrity and stability of the mechanism. Housing 10 is typically made of robust materials to resist external impacts and provide good sealing.

[0025] Rotating component 20: Located inside the housing 10, it can rotate around a specific axis. This rotating component 20 carries the laser generator and changes the direction of the laser generator by rotating itself, thereby adjusting the laser emission direction.

[0026] Laser generator 60: A device capable of generating a laser beam. In this embodiment, the laser generator is mounted inside the rotating member 20, and the direction of the laser beam emitted by it changes as the rotating member 20 rotates.

[0027] The angle between the laser direction and the length direction of the housing 10: refers to the angle between the central axis of the laser beam emitted by the laser generator and the length direction of the main body of the housing 10. By adjusting this angle, the laser beam can be projected at different angles.

[0028] Light-transmitting section 30: A region disposed on the housing 10, the material or structure of which allows the laser beam to pass through. The light-transmitting section 30 is usually made of transparent or translucent material, or is an opening, the function of which is to ensure that the laser emitted by the laser generator can smoothly exit the housing 10, while providing a certain degree of protection for the internal components.

[0029] The laser adjustment mechanism proposed in this application is characterized by its ingenious structural design, which enables flexible adjustment of the laser emission direction.

[0030] Specifically, the mechanism includes a housing 10, which can be constructed in various forms, such as a hollow cylindrical tubular structure or a rectangular box-like structure with an internal cavity. The primary function of the housing 10 is to provide a protected mounting space for the internal components and to serve as external support for the entire mechanism.

[0031] Inside the housing 10, a rotating component 20 is provided. This rotating component 20 can be a simple shaft with one end extending outside the housing 10 for easy operation; or it can be a hollow cylinder with its internal space used to accommodate other components. The rotating component 20 is designed to rotate smoothly around its central axis inside the housing 10, thereby providing the basic motion for adjusting the laser direction.

[0032] Furthermore, the laser generator is housed within the rotating component 20. For example, the laser generator can be directly fixed to the inner wall of the rotating component 20, or connected to the rotating component 20 via a bracket. With this configuration, the laser generator and the rotating component 20 form an integral unit, and the laser generator rotates synchronously when the rotating component 20 rotates.

[0033] Therefore, the laser generator is configured to rotate with the rotating component 20, adjusting the angle between the laser direction and the length direction of the housing 10. For example, when the rotating component 20 rotates from one initial position to another, the direction of the laser generator also changes, thereby changing the angle between the emitted laser beam and the length direction of the housing 10. This design allows users to flexibly project the laser at different angles according to actual needs.

[0034] In addition, a light-transmitting part 30 is provided on the housing 10. This light-transmitting part 30 can be a simple through hole or a window made of transparent glass, plastic, or other materials. The position of the light-transmitting part 30 is carefully designed to ensure that the laser beam emitted by the laser generator can exit from the inside of the housing 10 without obstruction.

[0035] In a preferred embodiment, the light-transmitting portion 30 is configured so that laser light can be emitted from it. This means that the size, shape, and materials used in the light-transmitting portion 30 are optimized to minimize laser energy attenuation and scattering, ensuring that the laser beam can be clearly and accurately projected onto the target area.

[0036] The following example will provide a more detailed explanation of the above technical solution: Suppose an interior renovation project is underway at location A. User A needs to mark an auxiliary line on a wall at a specific angle to the floor in order to install a slanted decorative panel. Traditional spirit levels can only provide horizontal or vertical reference lines, and some existing laser spirit levels typically only emit lasers in a fixed direction, failing to meet the need for multi-angle projection.

[0037] User A uses a laser adjustment mechanism proposed in this application. The housing 10 of this mechanism is designed as a compact cylindrical structure for easy hand-holding and placement. Inside the housing 10, a rotating component 20 is provided, which is constructed as a rotatable cylinder, forming a chamber for housing a laser generator. The laser generator is securely mounted in this chamber, with its emitting end facing the light-transmitting portion 30 on the housing 10.

[0038] When user A needs to project a laser line at a 30-degree angle to the ground, user A operates the external rotating component 20, causing the internal laser generator to rotate synchronously. As the rotating component 20 rotates, the laser generator's emission direction changes, causing the angle between the emitted laser beam and the length direction of the housing 10 to gradually increase from the initial 0 degrees. When the angle reaches 30 degrees, user A stops rotating. At this point, the laser beam emitted by the laser generator exits through the light-transmitting part 30 on the housing 10, forming a clear 30-degree inclined line on the wall.

[0039] Thus, the housing 10 provides overall support and protection, the rotating part 20 provides an adjustable rotation platform, the laser generator rotates with the rotating part 20 as the laser source, and the light-transmitting part 30 ensures that the laser is emitted smoothly. The entire mechanism works in concert, enabling user A to accurately and conveniently adjust the projection angle of the laser, thereby solving the limitations of traditional tools in multi-angle marking.

[0040] Based on the above examples, the laser adjustment mechanism proposed in this application demonstrates a significant technological contribution. Traditional existing spirit levels or fixed-angle laser spirit levels often cannot directly meet the needs of user A when they need to project auxiliary lines at a specific tilt angle. They may require complex auxiliary tools or multiple measurements to barely achieve this, resulting in low efficiency and difficulty in guaranteeing accuracy.

[0041] In contrast, the laser adjustment mechanism of this application, by setting a rotating component 20 within the housing 10 and integrating a laser generator within the rotating component 20, achieves direct and flexible adjustment of the angle between the laser direction and the length direction of the housing 10. For example, in the aforementioned renovation scenario, user A does not need to perform additional calculations or adjustments to the tool position; simply operating the rotating component 20 is sufficient to precisely adjust the laser beam to the required 30-degree angle. This integrated adjustable design greatly simplifies the operation process and improves work efficiency.

[0042] Furthermore, the light-transmitting part 30 ensures that the laser beam can be effectively emitted while protecting the internal precision components. Overall, the solution of this application provides a compact, easy-to-operate solution that allows for precise adjustment of the laser projection angle, effectively overcoming the limitations of existing technologies where the laser emission direction is fixed and the angle cannot be flexibly adjusted, thus meeting users' actual needs for multi-angle laser projection.

[0043] This application further proposes that the rotation angle of the rotating member 20 is in the range of [0°, 90°].

[0044] Specifically, the rotation angle range of the rotating component 20 refers to the range of angles within the housing 10 that the rotating component 20 can rotate. This range defines the angle between the direction of the laser emitted by the laser generator and the length direction of the housing 10. Limiting this rotation angle range to [0°, 90°] means that the laser direction can be continuously adjusted from parallel to the length direction of the housing 10 (0°) to perpendicular to the length direction of the housing 10 (90°). This angle range limitation can be achieved in various ways. For example, a mechanical limiting structure can be provided on the rotating component 20 or the housing 10. When the rotating component 20 rotates to the limit position of 0° or 90°, the mechanical limiting structure will prevent it from rotating further. Alternatively, it can be achieved through electronic control. For example, an angle sensor (such as a rotary encoder or Hall sensor) can be integrated into the drive mechanism of the rotating component 20, and a controller can preset electronic limits of 0° and 90°. When the sensor detects that the rotating component 20 has reached or is close to these angles, the controller will stop or reverse the rotation of the rotating component 20.

[0045] The solution of this application limits the rotation angle range of the rotating component 20 in the laser adjustment mechanism to [0°, 90°], enabling the laser generator housed within the rotating component 20 to precisely adjust the direction of its emitted laser to form any angle between 0° and 90° with the length direction of the housing 10. In the aforementioned laser adjustment mechanism, the rotating component 20 carries the laser generator and is responsible for adjusting the laser direction, while the housing 10 provides support and protection. By precisely limiting the rotation range of the rotating component 20, the determinism and repeatability of the laser direction adjustment are ensured. For example, when horizontal laser projection is required, the rotating component 20 can be adjusted to the 0° position; when vertical laser projection is required, it can be adjusted to the 90° position. This limitation not only solves the problem of unclear angle adjustment range in traditional solutions but also enables the laser adjustment mechanism to cover all commonly used measurement angles from horizontal to vertical, greatly improving the functionality and practicality of the mechanism.

[0046] As a specific implementation, the rotation angle range of the rotating member 20 can be achieved as follows: a protrusion 205 is provided on the outer edge of the rotating member 20, and a first limiting block 106 and a second limiting block 107 are provided on the outside of the housing 10. The first limiting block 106 and the second limiting block 107 form a 90° angle. During the rotation process, when the protrusion 205 rotates to 0° and 90°, the protrusion 205 is blocked by the first limiting block 106 and the second limiting block 107 and cannot continue to rotate.

[0047] Through the above technical solution, this application ensures that the laser direction adjustment of the laser adjustment mechanism has a clear and controllable range, avoiding problems such as inaccurate adjustment or inability to meet specific angle requirements due to uncertain angle range. This precise angle limitation allows users to conveniently and accurately adjust the laser direction to the required horizontal, vertical, or arbitrary intermediate angle, thereby significantly improving the accuracy and reliability of the laser adjustment mechanism in measurement and positioning applications.

[0048] In some of the solutions described above in this application, a rotating component 20 is proposed to rotate the laser generator to adjust the laser angle. However, in the process of its implementation, the structure of the rotating component 20 may not be compact enough, inconvenient to operate, or have poor sealing, resulting in inaccurate adjustment or susceptibility to environmental influences.

[0049] In this regard, this application further proposes that the rotating member 20 includes an operating part 201 located outside the housing 10 and a main body part 202 located inside the housing 10. The operating part 201 is used to drive the main body part 202 to rotate synchronously. A mounting cavity 2021 is formed inside the main body part 202. The laser generator is located inside the mounting cavity 2021. The light-emitting part of the laser generator faces the light-transmitting part 30. An opening is formed on the main body part 202 in the mounting cavity 2021. The openings are arranged opposite to each other. The light-emitting part is located in the opening near the light-transmitting part 30.

[0050] Specifically, the operating part 201 is the component in the rotating part 20 that the user can directly contact and apply force to. It can be a knob, a lever, a handle, or a ring with a friction texture, designed to provide an interface that facilitates angle adjustment for the user. The main body 202 is the component in the rotating part 20 located inside the housing 10, carrying the laser generator and actually performing rotational adjustments. It can be a cylindrical, conical, or irregularly shaped rotating shaft, hollow inside or with a cavity, serving as the carrier of the laser generator and linked with the operating part 201. The operating part 201 is used to drive the main body 202 to rotate synchronously, aiming to ensure that external adjustments made by the user through the operating part 201 are accurately and in real time transmitted to the internal main body 202, thereby realizing the angle adjustment of the laser generator. This synchronous rotation can be achieved by connecting the operating part 201 and the main body 202 in a one-piece molding process, forming a whole; or by using mechanical connections such as key connections, pin connections, or threaded connections to keep them synchronized during rotation. A mounting cavity 2021 is formed within the main body 202. This mounting cavity 2021 is a space within the main body 202 used to accommodate and fix the laser generator. It can be an inner hole that matches the shape of the laser generator, such as a cylindrical hole or a square hole; or it can be an irregularly shaped cavity with positioning structures (such as slots or limiting protrusions), designed to provide a protected and stable mounting position for the laser generator. The laser generator is located within the mounting cavity 2021, designed to securely mount the laser generator inside the main body 202, allowing it to rotate with the main body 202 and be protected by it. The laser generator can be fixed in the mounting cavity 2021 by interference fit, screw fixing, adhesive, snap-fit, etc. The light-emitting part of the laser generator faces the light-transmitting part 30, designed to ensure that the laser emitted by the laser generator can accurately point to the light-transmitting part 30, thereby smoothly exiting the housing 10. This can be achieved by aligning the emitting end of the laser generator with the direction of the light-transmitting part 30 during installation; or by providing a guiding structure within the mounting cavity 2021 to force the laser generator to be installed in a specific orientation. The mounting cavity 2021 has openings formed on the main body 202, which are oppositely positioned. These openings serve as channels connecting the mounting cavity 2021 to the external environment (or the light-transmitting part 30). These openings can be through holes, such as circular or rectangular holes, formed on the sidewall of the main body 202; alternatively, a portion of the main body 202 can be cut away to form an arc-shaped or straight groove, designed to allow the laser to exit from inside the mounting cavity 2021 and provide a path for observing or adjusting the laser generator. The opposite arrangement means there are at least two openings, one for laser emission and the other potentially for installation or auxiliary positioning. The emitting part is located in the opening near the light-transmitting part 30, designed to optimize the laser's emission path, reduce the distance the laser travels internally, thereby reducing optical path loss and ensuring that the laser can pass clearly and unobstructed through the light-transmitting part 30.This can be achieved by placing the light-emitting end of the laser generator at the opening closest to the light-transmitting part 30, or by making the light-emitting part flush with or slightly protruding from the edge of the opening.

[0051] The solution in this application designs the rotating component 20 as an external operating part 201 and an internal main body 202, allowing users to conveniently adjust the laser angle from outside the housing 10, while compactly integrating the laser generator and its rotating mechanism inside the housing 10. The external operating part 201 rotates synchronously with the internal main body 202, ensuring precise transmission of user operations. The mounting cavity 2021 formed within the main body 202 provides a stable mounting space for the laser generator, enabling it to rotate with the main body 202. The light-emitting part of the laser generator is precisely oriented towards the light-transmitting part 30 and located in an opening near the light-transmitting part 30. This structural layout minimizes the propagation distance and optical path loss of the laser internally, ensuring the efficiency and accuracy of laser emission. This design cleverly separates the operating interface from the internal working mechanism, achieving user-friendly operation while ensuring the structural compactness of the mechanism and effectively protecting the internal precision components from external environmental influences, thereby improving the accuracy and reliability of laser angle adjustment.

[0052] In one specific implementation, the operating part 201 can be a cylindrical knob with an anti-slip texture, its outer diameter being slightly larger than the opening on the housing 10, facilitating gripping and rotation. The main body 202 can be a hollow cylinder, one end of which is integrally injection molded to the operating part 201, while the other end extends into the housing 10. The operating part 201 and the main body 202 are integrally molded to ensure that they move synchronously without gaps or lag during rotation. The cylindrical cavity inside the main body 202 serves as a mounting cavity 2021, its inner diameter closely fitting the outer diameter of the laser generator. The laser generator can be a standard semiconductor laser module, fixed in the mounting cavity 2021 by a snap-fit ​​structure or a small amount of adhesive. The emitting end face of the laser module faces the light-transmitting part 30 on the housing 10. An arc-shaped slot is formed on the side of the main body 202 near the light-transmitting part 30 for laser emission; a smaller opening may also be formed on the opposite side for mounting or heat dissipation of the laser generator. The light-emitting end face of the laser module is flush with the edge of the arc-shaped groove on the main body 202 to ensure that the laser is emitted without obstruction.

[0053] Through the above technical solution, the rotating component 20 is designed as an external operating part 201 and an internal main body part 202, allowing users to conveniently adjust the laser angle from outside the housing 10. Simultaneously, the laser generator and its rotating mechanism are compactly integrated inside the housing 10, effectively solving the problems of inconvenient operation and insufficient structural compactness in traditional solutions. The mounting cavity 2021 formed within the main body part 202 and the precise installation of the laser generator, along with the light-emitting part facing the light-transmitting part 30 and located near the opening of the light-transmitting part 30, minimize optical path loss and ensure the efficiency and accuracy of laser emission. This design not only improves the reliability and accuracy of the laser adjustment mechanism but also effectively avoids the influence of the external environment on internal precision components by optimizing the internal structure, thereby solving the technical problem of inaccurate adjustment or susceptibility to environmental influences due to poor sealing.

[0054] In some of the solutions described above in this application, a housing 10 is proposed to accommodate the rotating component 20 and the laser generator. However, in this process, the structure of the housing 10 may lack an effective sealing mechanism, which may cause external environmental factors such as dust or moisture to easily enter the internal space, affecting the stable operation of the laser generator and the accuracy of laser adjustment, thereby reducing the reliability and service life of the overall mechanism.

[0055] In response, this application proposes an improved solution, wherein the housing 10 includes a cover 101 and a base 102, the cover 101 and the base 102 are fixedly connected, a through hole is formed on the cover 101 for the operating part 201 to extend out, and the cover 101 and the base 102 are connected to form an opening for placing the light-transmitting part 30. In addition, a sealing groove 1011 is provided on the inner side of the cover 101, and a sealing ring 103 is provided in the sealing groove 1011.

[0056] Specifically, the housing 10, serving as the external protective structure of the laser adjustment mechanism, is designed to consist of two main components: a cover 101 and a base 102. This split structure facilitates the installation, adjustment, and maintenance of internal components. The cover 101 typically refers to the upper or detachable part of the housing 10, while the base 102 refers to the lower or fixed part. For example, the cover 101 can be manufactured using injection molding or die casting processes, and the base 102 can be manufactured using metalworking or high-strength plastic molding. The cover 101 and base 102 are reliably connected to form a stable and enclosed whole. This fixed connection ensures that the housing 10 maintains its structural integrity under external impact or long-term use, preventing component loosening. For example, the fixed connection can be achieved using screw fastening, snap-fit ​​joints combined with adhesive bonding, ultrasonic welding, or thermoforming riveting. The sealing groove 1011 is a recess specifically designed to accommodate the sealing element, located on the inner side of the cover 101, i.e., the contact surface where it engages with the base 102. The shape and dimensions of the sealing groove 1011 are matched to the selected seal, designed to provide a precise installation position and compression space for the seal. For example, the sealing groove 1011 can be designed as a rectangular groove, a U-shaped groove, or a dovetail groove, with its depth and width optimized according to the cross-sectional dimensions and compression ratio of the sealing ring 103. The sealing ring 103 is an annular or irregularly shaped seal made of an elastic material, which is placed within the sealing groove 1011 to form a continuous sealing barrier when the cover 101 and the base 102 are engaged. The sealing ring 103 fills the tiny gaps between the mating surfaces through its own elastic deformation, thereby effectively preventing external media (such as dust and moisture) from entering the interior of the housing 10. For example, the sealing ring 103 can be an O-ring, a rectangular ring, a lip seal 103, or a custom-shaped seal 103, and its material can be nitrile rubber, silicone rubber, fluororubber, or polyurethane, depending on the working environment and sealing requirements of the mechanism.

[0057] The laser adjustment mechanism of this application, based on the basic housing 10 structure, constructs an integrated framework that facilitates assembly and maintenance by decomposing the housing 10 into two separable components: a cover 101 and a base 102, and tightly connecting them using a fixed connection. To effectively address the potential impact of the external environment on the internal precision components, this solution strategically provides a sealing groove 1011 on the inner surface of the cover 101. This sealing groove 1011 serves as a pre-designed receiving space, precisely positioning and supporting the sealing ring 103. When the cover 101 and the base 102 are tightly joined by the fixed connection, the sealing ring 103 is appropriately compressed between them, and its elastic deformation can fully fill the tiny gaps between the mating surfaces, thus forming a continuous and reliable physical barrier. This barrier effectively prevents external dust, moisture, or other contaminants from intruding into the housing 10, protecting the internal rotating components 20 and the laser generator from environmental corrosion. This structural design ensures that the laser generator maintains a stable operating state under various working conditions and maintains the accuracy of laser direction adjustment, significantly improving the reliability and service life of the entire laser adjustment mechanism.

[0058] In one specific implementation, the housing 10 can be made of high-strength engineering plastic (such as ABS or PC) through injection molding, wherein the cover 101 and the base 102 are molded independently. The cover 101 and the base 102 can be fixedly connected using multiple self-tapping screws, with precisely corresponding screw holes to ensure a tight fit. On the mating surface between the cover 101 and the base 102, a rectangular sealing groove 1011 can be formed circumferentially on the inner side of the cover 101. The dimensions of the sealing groove 1011 match the selected O-ring 103. For example, a silicone rubber O-ring with good aging resistance and moisture and heat resistance can be selected and pre-installed in the sealing groove 1011 of the cover 101. When the cover 101 is fastened to the base 102 with screws, the O-ring 103 is uniformly compressed, thereby forming a continuous and effective sealing layer between the cover 101 and the base 102.

[0059] Through the above technical solution, the laser adjustment mechanism of this application effectively solves the shortcomings of the traditional housing 10 structure in terms of sealing. By designing the housing 10 as a combination of a cover 101 and a base 102, and supplementing it with a fixed connection, not only is the assembly and maintenance process of the internal components simplified, but more importantly, a sealing groove 1011 and a sealing ring 103 are set on the inner side of the cover 101, forming a reliable sealing barrier. This allows the internal space of the laser adjustment mechanism to effectively isolate dust, moisture and other contaminants from the external environment, thereby protecting the internal rotating parts 20 and the laser generator. When the laser adjustment mechanism is used for a long time or works in harsh environments, it can significantly reduce the failure rate caused by environmental factors, ensure the stable output of the laser generator and the accuracy of laser direction adjustment, and greatly improve the reliability, durability and service life of the entire mechanism.

[0060] In some embodiments described above, the main body 202 is proposed to realize the rotational adjustment of the laser generator and ensure the sealing of the mechanism. However, during its implementation, the side of the main body 202 near the operating part 201 is prone to displacement or loosening due to operational forces, resulting in a decrease in laser adjustment accuracy and damage to sealing performance. To address this, this application further proposes that a fixing clamp 203 be provided on the side of the main body 202 near the operating part 201.

[0061] The main body 202 is a component of the rotating part 20, and has an internal cavity 2021 for accommodating the laser generator. It rotates synchronously with the operating part 201 to adjust the laser direction. During the operation of the laser adjustment mechanism, the main body 202 needs to maintain precise positioning and stable rotation to ensure the accuracy of the laser emission angle. The operating part 201 is located outside the housing 10 and is used for manual operation by the user. Its rotation drives the main body 202 to rotate synchronously, thereby adjusting the laser direction. The operating part 201 applies force to the user's hand during rotation; therefore, the connection area between the operating part 201 and the main body 202 is a region of concentrated force and prone to relative displacement. The fixing clamp 203 is a mechanical element used to limit relative displacement of components or provide axial positioning. Its concept is to firmly fix the main body 202 in a specific position by externally applied radial or axial force, preventing axial or radial loosening or displacement during operation due to force. The fixing clamp 203 can be implemented in various ways. For example, it can be a split clamp, fastened to the outside of the main body 202 with bolts to form a ring-like fixation; it can also be a conical sleeve that mates with the main body 202, and axial locking is achieved by tightening a nut; or it can be a press-fit ring-shaped part that provides fixing force through an interference fit. All these implementation methods aim to provide reliable mechanical constraints to enhance the stability of the connection area between the main body 202 and the operating part 201.

[0062] The solution proposed in this application addresses the potential displacement or loosening of the main body 202 during operation by providing a fixing clamp 203 on the side of the main body 202 near the operating part 201. Specifically, in the laser adjustment mechanism, the laser generator is housed in a mounting cavity 2021 within the main body 202 and rotates with the main body 202 to adjust the laser direction. The operating part 201 is located outside the housing 10 and is manually rotated by the user, driving the main body 202 to rotate synchronously via a mechanical connection. Since the operating part 201 applies torque and axial force to the user's hand during rotation, if the connection between the main body 202 and the operating part 201 is not secure enough, the main body 202 may experience slight axial or radial displacement, leading to a positional deviation of the laser generator, affecting the accuracy of laser direction adjustment, and potentially even damaging the sealing structure inside the housing 10. By setting a fixing clamp 203, the clamp can apply radial or axial restraint force to the main body 202, firmly locking it in a preset position. This effectively counteracts the external force applied by the operating part 201, preventing unnecessary displacement or loosening of the main body 202 during rotation. This fixing method ensures the connection stability between the main body 202 and the operating part 201, allowing the laser generator to maintain precise positioning during adjustment, thus guaranteeing the accuracy of laser direction adjustment. Furthermore, the stable main body 202 also indirectly maintains the sealing integrity of the mechanism, avoiding the risk of seal failure due to component loosening.

[0063] In one specific implementation, the fixing clamp 203 can be a ring-shaped component made of metal, with its inner diameter tightly fitting the outer diameter of the main body 202. This ring-shaped component can be designed with one or more radially threaded holes. A screw passes through the threaded holes and is tightened, causing the screw tip to abut against or embed in a corresponding groove on the outer wall of the main body 202, thereby achieving radial fixation and axial positioning of the main body 202. For example, a split clamp can be used, consisting of two halves connected by bolts. When the bolts are tightened, the clamp tightens and tightly embraces the main body 202, providing a strong radial clamping force. Alternatively, the fixing clamp 203 can also be a locking ring with internal threads, engaging with a corresponding external thread on the outer side of the main body 202. By rotating the locking ring, a threaded connection is formed with the main body 202, and axial compression is formed between the end face of the locking ring and a positioning surface inside the operating part 201 or the housing 10, thereby preventing axial displacement of the main body 202.

[0064] By employing the aforementioned technical solution, a fixing clamp 203 is installed on the side of the main body 202 near the operating part 201, effectively enhancing the mechanical stability of the connection area between the main body 202 and the operating part 201. This significantly reduces the possibility of axial or radial displacement of the main body 202 due to force during user operation, thereby ensuring the positional accuracy of the laser generator during rotational adjustment. Therefore, this solution guarantees the accuracy and repeatability of laser direction adjustment, avoiding laser projection angle deviations caused by component loosening. Simultaneously, the stable main body 202 indirectly maintains the sealing integrity of the mechanism's internal structure, extending its service life and improving the overall reliability and durability of the laser adjustment mechanism.

[0065] In traditional laser adjustment mechanisms, when the fixing clamp 203 is used to fix the main body 202, there may be a defect in the sealing between the fixing clamp 203 and the sealing ring 103, which allows external contaminants such as dust or moisture to enter the interior of the housing 10, affecting the accuracy of the laser generator and the reliability of the mechanism.

[0066] In this regard, this application further proposes that the sealing gasket 104 is located between the fixing clamp 203 and the sealing ring 103.

[0067] The sealing gasket 104 is a component made of elastic or semi-elastic material used to fill the gap between two or more mating surfaces to prevent leakage of fluid or solid particles, and its function is to provide an effective sealing barrier. The sealing gasket 104 can be made of various materials, such as rubber (e.g., nitrile rubber, silicone rubber, fluororubber), polytetrafluoroethylene, cork, fiber materials, or metal. Its shape can be designed according to the geometry of the mating surfaces, such as annular, rectangular, or irregular shapes. The fixing clamp 203 is a mechanical device used to tightly fix two or more components together; in this application, it is used to fix the main body 202. The fixing clamp 203 typically has a certain degree of elasticity or adjustability so that appropriate clamping force can be applied during installation. This can be achieved, but is not limited to: bolt-tightening clamps, applying pressure by tightening bolts; spring clamps, using the elastic force of a spring for fixing; or quick fixing through a snap-fit ​​structure. The sealing ring 103 is an annular sealing element, typically made of elastic material, used to form a seal between two mating surfaces to prevent leakage of fluid or particles. The sealing ring 103 can take various forms, such as O-rings, X-rings, rectangular rings, or lip seals 103. Its material is typically rubber (such as nitrile rubber, silicone rubber, or fluororubber) or polyurethane to provide good elasticity and wear resistance.

[0068] The solution of this application forms a multi-layer sealing structure by placing a sealing gasket 104 between the fixing clamp 203 and the sealing ring 103. Specifically, in the laser adjustment mechanism, the housing 10 includes a cover 101 and a base 102. A sealing groove 1011 is formed on the inner side of the cover 101, and a sealing ring 103 is disposed in the sealing groove 1011. The sealing ring 103 is mainly responsible for sealing between the cover 101 and the base 102. At the same time, a fixing clamp 203 is provided on the side of the main body 202 near the operating part 201. The fixing clamp 203 is used to fix the main body 202. However, in the mating area between the fixing clamp 203 and the sealing ring 103, there may be a small gap or a loose fit, thus forming a potential leakage path. By introducing a sealing gasket 104 and precisely positioning it between the retaining clamp 203 and the sealing ring 103, the sealing gasket 104 effectively fills the tiny gap between them and withstands the pressure applied by the retaining clamp 203, thus forming a tighter and more reliable sealing barrier together with the retaining clamp 203 and the sealing ring 103. This structural combination ensures that while the main body 202 is secured by the retaining clamp 203, the sealing performance of the sealing ring 103 is further strengthened and supplemented, thereby effectively preventing external contaminants (such as dust and moisture) from entering the interior of the housing 10 through this area.

[0069] The following is a specific example: the sealing gasket 104 can be an annular gasket made of wear-resistant and aging-resistant nitrile rubber material. Its thickness matches the expected gap between the fixing clamp 203 and the sealing ring 103, and is slightly larger than this gap to ensure compression sealing. The fixing clamp 203 can be an annular component made of engineering plastic or lightweight metal (such as aluminum alloy), whose inner diameter matches the outer diameter of the main body 202, and has a threaded hole on the outside, which is fastened to the corresponding structure on the cover 101 or the base 102 by screws. The sealing ring 103 can be a standard O-ring rubber ring, placed in a pre-set annular sealing groove 1011 inside the cover 101. During assembly, the sealing ring 103 is first installed into the sealing groove 1011 of the cover 101. Then, the main body 202 is inserted into the internal space formed by the cover 101 and the base 102. Next, the sealing gasket 104 is placed between the fixing clamp 203 and the installed sealing ring 103. Finally, the fixing clamp 203 is tightened with screws to apply uniform pressure to the sealing gasket 104, thereby compressing the sealing gasket 104 and tightly fitting it with the fixing clamp 203 and the sealing ring 103 to form a reliable seal.

[0070] Through the above technical solution, in the laser adjustment mechanism, the sealing gasket 104 is placed between the fixing clamp 203 and the sealing ring 103, which can effectively fill the potential gap between the fixing clamp 203 and the sealing ring 103, forming an additional sealing barrier. This significantly enhances the sealing performance inside the housing 10, preventing external dust, moisture and other contaminants from entering the housing 10, thereby protecting the internal laser generator and its precision components from environmental influences. Therefore, this solution improves the dustproof and waterproof capabilities and overall reliability of the laser adjustment mechanism, ensures the accuracy of laser direction adjustment and the long-term stability of the mechanism, extends the product's service life, and reduces the failure rate caused by environmental factors.

[0071] In some of the solutions described above in this application, the operation unit 201 and the main body 202 are provided to rotate the laser generator and adjust the laser direction. However, in the process of implementation, the user cannot intuitively know the angle between the current laser direction and the length direction of the housing 10, which leads to inconvenience in adjustment and insufficient accuracy.

[0072] In this regard, this application further proposes that the operation part 201 is located outside the cover 101, and the main body 202 is located in the internal space formed between the cover 101 and the base 102. An indicator disk 204 is formed on the side of the operation part 201 near the cover 101, and a scale area 105 is formed on the cover 101. The indicator disk 204 and the scale area 105 are used to indicate the angle value formed between the current laser direction and the length direction of the housing 10.

[0073] Specifically, the operating part 201 is part of the rotating component 20 and is used by the user to manually adjust the laser direction. The operating part 201 can be designed as a knob, handle, or dial, and its outer surface can have a non-slip texture or an ergonomic design for easy gripping and rotation. Alternatively, the operating part 201 can be an integral structure with the main body 202, extending to the outside through an opening in the housing 10, or operated via a non-contact method such as magnetic coupling. The main body 202 is the main part of the rotating component 20, carrying the laser generator and linked with the operating part 201. The main body 202 is located in the internal space formed between the cover 101 and the base 102. This internal space can be a precisely machined cavity whose inner wall matches the shape of the main body 202, ensuring the stability and coaxiality of the main body 202 during rotation. Alternatively, the internal space can also limit the movement trajectory of the main body 202 through multiple support points or guide structures, such as using bearings or bushings to support the rotation of the main body 202. The indicator dial 204 is a visible part of the operating section 201, used to indicate the current angle. The indicator dial 204 can be a disc integrally formed with the operating section 201, with markings such as arrows, lines, or numbers engraved on its edge or surface. Alternatively, the indicator dial 204 can be a separate component, fixed to the operating section 201 by snaps, threads, or adhesives, and rotate synchronously with the operating section 201. The scale area 105 is a fixed area on the cover 101 used to provide an angle reference. The scale area 105 can be scale lines and numerical markings formed on the surface of the cover 101 by laser engraving, screen printing, or mold forming. Alternatively, the scale area 105 can be a separate scale ring, fixed to the cover 101 by embedding, adhesives, or screws. The indicator dial 204 and the scale area 105 work together to provide an intuitive angle reading. Indicator marks on dial 204, such as pointers or specific edges, are aligned with scale lines on scale area 105 to display precise angle values. Alternatively, dial 204 may have a window or transparent area through which the numbers on scale area 105 can be seen, or dial 204 itself may have numbers aligned with fixed marks on scale area 105.

[0074] The solution of this application places the operating part 201 outside the cover 101, allowing the user to directly contact and rotate the rotating part 20 to adjust the direction of the laser generator. The main body 202 is securely encapsulated in the internal space formed between the cover 101 and the base 102, ensuring the stability and protection of the laser generator during adjustment. Furthermore, an indicator disk 204 is formed on the side of the operating part 201 near the cover 101, and this indicator disk 204 rotates synchronously with the operating part 201. Simultaneously, a fixed scale area 105 is formed on the cover 101. When the user rotates the operating part 201, the indicator disk 204 rotates accordingly, and the indicator marks on it move relative to the scale area 105 on the cover 101, thereby displaying in real time and intuitively the angle value formed between the current laser direction and the length direction of the housing 10. This design allows the user to accurately understand the laser projection angle without the need for external measuring tools when adjusting the laser direction, greatly improving the convenience and accuracy of adjustment. In this way, this application effectively solves the problem of missing angle indication in traditional solutions while maintaining the compact structure of the laser adjustment mechanism, making the laser adjustment mechanism more complete and easier to use.

[0075] The following is a specific example. As a concrete implementation, the operating part 201 can be designed as a knob with a knurled texture, its top flush with the outside of the cover 101, facilitating grip and rotation by the user's fingers. The main body 202 can be a cylindrical structure, its outer surface tightly fitting the cylindrical internal space formed between the cover 101 and the base 102, achieving smooth rotation through bearing support. The indicator dial 204 can be a circular dial integrally formed with the knob, its edge engraved with equally spaced graduations from 0° to 90°, marked with corresponding angle values, for example, one mark every 10 degrees. A fan-shaped scale area 105 can be formed on the cover 101 at the position corresponding to the indicator dial 204 using laser etching. This scale area 105 precisely matches the graduations of the indicator dial 204 and includes a fixed indicating arrow or reference line. When the user rotates the knob, the scale line on the indicator dial 204 will align with the fixed indicator arrow on the cover 101, thus intuitively displaying the current angular position of the laser generator. For example, when the "45" scale line on the indicator dial 204 aligns with the indicator arrow on the cover 101, it indicates that the angle between the laser direction and the length direction of the housing 10 is 45 degrees.

[0076] Through the above technical solution, users can intuitively and accurately obtain the angle value formed between the current laser direction and the length direction of the housing 10 when adjusting the laser direction, avoiding the trouble of blind adjustment or the need for additional measuring tools, and significantly improving the convenience of operation and the accuracy of adjustment. This design allows the laser adjustment mechanism to maintain its compact structure while greatly enhancing its usability and user experience, especially suitable for scenarios requiring precise angle positioning.

[0077] In some of the solutions described above in this application, a light-transmitting part 30 is proposed to allow the laser to be emitted from the housing 10. However, in this process, the fixing method of the light-transmitting part 30 may not be stable enough, which may easily lead to poor sealing or complicated installation, affecting the accuracy of laser projection and the reliability of the mechanism.

[0078] In this regard, this application further proposes that the light-transmitting part 30 is a curved plate structure made of transparent material, which engages with the snap-fit ​​groove 40 formed on the cover 101 and the base 102.

[0079] The light-transmitting section 30 is the component in the laser adjustment mechanism that allows the laser beam to pass through. Its core function is to ensure that the laser beam exits from the mechanism with minimal loss and scattering. This transparent material can be optical glass, such as K9 glass or fused silica, which have excellent light transmittance and optical uniformity, suitable for applications requiring high laser beam quality. Alternatively, high-molecular transparent materials, such as polycarbonate or polymethyl methacrylate, can be used. These materials have good impact resistance and processing performance, and are relatively inexpensive, suitable for applications requiring structural strength and economy. A curved plate structure refers to the light-transmitting section 30 having a certain curvature or curved shape, rather than a planar structure. This design allows the light-transmitting section 30 to provide a continuously changing surface to accommodate the continuous change in laser direction as the laser generator rotates with the rotating component 20. This curved plate structure can be designed as an arc-shaped plate, such as a quarter circle or larger / smaller arc segments, to provide uniform curvature. It can also be designed as a non-arc-shaped plate, such as a parabolic or elliptical arc, to meet specific optical path or spatial layout requirements. The snap-fit ​​groove 40 is a method of achieving quick and secure connection of components through structural fit. Here, the light-transmitting part 30 mechanically engages with the snap-fit ​​groove 40 pre-formed on the cover 101 and the base 102 through its edge structure. The snap-fit ​​groove 40 can be designed as a U-shaped groove with barbs or protrusions, and the edge of the light-transmitting part 30 is correspondingly formed with matching grooves or flanges, achieving a tight engagement through elastic deformation or pressing. The snap-fit ​​groove 40 can also be a dovetail groove or a T-shaped groove, with the edge of the light-transmitting part 30 machined into a corresponding dovetail or T-shaped cross-section, fixed by sliding or insertion, and can be supplemented with a limiting structure to prevent detachment.

[0080] The solution of this application achieves a stable installation and effective sealing of the light-transmitting part 30 by designing the light-transmitting part 30 as a curved plate structure made of transparent material and fixing it to the cover 101 and the base 102 using a snap-fit ​​groove 40. When the laser generator rotates within the rotating part 20, the laser beam it emits will be directed towards the light-transmitting part 30 at different angles. Since the light-transmitting part 30 is a curved plate structure, its arc-shaped surface can adapt to changes in the laser beam angle, ensuring that the laser can smoothly penetrate and exit the housing 10 in different projection directions. The selection of transparent material ensures that the laser can be emitted from the inside of the mechanism efficiently and without damage. The light-transmitting part 30 is fixed to the housing 10 (specifically the cover 101 and the base 102) by the snap-fit ​​groove 40. The snap-fit ​​groove 40 pre-formed on the cover 101 and the base 102 precisely matches the edge of the curved plate structure, allowing the light-transmitting part 30 to be installed quickly and stably. This snap-fit ​​method not only simplifies the assembly process but also effectively improves the sealing performance between the light-transmitting part 30 and the housing 10 through the tight fit between the structures. In particular, when the housing 10 includes a cover 101 and a base 102, and the inner side of the cover 101 has a sealing groove 1011 and a sealing ring 103, the snap-fit ​​fixing of the light-transmitting part 30 can work synergistically with the sealing ring 103. The tightness of the snap-fit ​​helps to press the light-transmitting part 30 against the sealing ring 103, further enhancing the dustproof and waterproof capabilities of the entire mechanism and protecting the internal laser generator and rotating parts 20 from external environmental influences. In addition, the curved plate structure supports the ability to project lasers at multiple angles. In conjunction with the operating part 201, the indicator dial 204, and the scale area 105 (used to indicate the angle between the laser direction and the length direction of the housing 10), the user can intuitively and accurately adjust the laser projection angle and ensure that the laser can always be effectively emitted from the light-transmitting part 30 during the adjustment process.

[0081] In one specific implementation, the light-transmitting part 30 can be integrally molded from a high-transmittance polycarbonate material. Specifically, the light-transmitting part 30 is a quarter-circle arc-shaped plate, the curvature of which matches the angle range swept by the laser beam when the laser generator rotates within the rotating component 20. On the mating surface of the cover 101 and the base 102, a continuous U-shaped locking groove 40 is formed along the mounting position of the light-transmitting part 30. The inner wall of the U-shaped locking groove 40 can be designed with a small barb structure. Correspondingly, flanges that mate with the U-shaped locking grooves 40 are designed on both sides of the light-transmitting part 30. During installation, by aligning the flanges of the light-transmitting part 30 with the U-shaped locking grooves 40 on the cover 101 and the base 102, and applying appropriate pressure, the flanges elastically deform and engage with the grooves, thereby achieving rapid and stable fixation of the light-transmitting part 30. This snap-fit ​​method ensures a tight physical connection between the light-transmitting part 30, the cover 101, and the base 102. At the same time, its structural design also facilitates disassembly when maintenance is required.

[0082] Through the above technical solution, the light-transmitting part 30 adopts a curved plate structure made of transparent material, which is engaged with the locking groove 40 formed on the cover 101 and the base 102, effectively solving the problems of unstable fixation, poor sealing, and complex installation of traditional light-transmitting parts 30. The transparent material ensures that the laser can be emitted from the inside of the mechanism efficiently and without damage, avoiding light loss and scattering, and ensuring the accuracy of laser projection. The curved plate structure provides a continuous arc-shaped emission surface, allowing the laser beam to pass smoothly at a continuously changing projection angle when the laser generator rotates the rotating part 20, thereby supporting the function of multi-angle and flexible laser projection of the laser adjustment mechanism. The locking method of the locking groove 40 enables the light-transmitting part 30 to be installed quickly and conveniently, significantly simplifying the assembly process. Meanwhile, this tight snap-fit ​​structure, combined with the housing 10 (cover 101 and base 102), and especially in synergy with the sealing groove 1011 and sealing ring 103 inside the cover 101, greatly enhances the overall sealing performance of the mechanism. This effectively prevents external environmental factors such as dust and moisture from corroding the internal precision components, thereby improving the reliability, durability, and service life of the laser adjustment mechanism. Overall, this solution optimizes the structural design and assembly process of the mechanism while ensuring laser emission performance, thus improving product stability and user experience.

[0083] In some of the solutions described above in this application, a curved plate structure is proposed for the light-transmitting part 30 to allow the laser to be emitted and snapped into the snap-fit ​​groove 40 of the cover 101 and the base 102. However, in its implementation, the shape of the curved plate structure may not be specific or optimized enough, resulting in inaccurate laser projection angle coverage or insufficient structure, affecting the flexibility of laser adjustment and installation stability.

[0084] In response, this application further proposes a curved plate with a quarter-circle curved structure. This technical feature refers to the fact that the curved plate structure used in the light-transmitting portion 30 specifically presents an arc-shaped plate formed by a quarter of a circle's circumference. This shape defines the geometric profile of the light-transmitting portion 30, giving it a specific range of curvature and angles. As one implementation, the arc-shaped plate can be integrally manufactured from a single transparent material (e.g., optical-grade plastics such as polymethyl methacrylate (PMMA) or polycarbonate (PC), or special glass) through processes such as injection molding, hot bending, or precision cutting and grinding. Alternatively, multiple smaller transparent arc-shaped segments can be precisely spliced ​​or bonded together to form a single, integral quarter-circle arc-shaped plate.

[0085] The solution in this application precisely defines the curved plate structure of the light-transmitting part 30 as a quarter-circle arc plate, ensuring that the laser beam emitted by the laser generator can always smoothly pass through the transparent area of ​​the arc plate when the laser adjustment mechanism is in operation. This specific arc design is highly matched with the rotation angle range of the rotating part 20 (typically 0° to 90°), so that when the laser generator adjusts the angle formed between the laser direction and the length direction of the housing 10, the laser projection angle can be precisely covered, avoiding laser direction deviation or obstruction caused by the mismatch of the shape of the light-transmitting part 30. At the same time, the quarter-circle arc plate structure has good compactness and can fit tightly with the snap-fit ​​grooves 40 formed on the cover 101 and the base 102, enhancing the connection stability and sealing between the light-transmitting part 30 and the housing 10, thereby improving the structural reliability and installation stability of the entire laser adjustment mechanism.

[0086] In one specific implementation, the aforementioned curved plate structure can be integrally molded into a quarter-circle arc-shaped plate from optically transparent polycarbonate material using a precision injection molding process. The arc-shaped plate has a uniform thickness, and its surface undergoes optical treatment to ensure minimal loss and distortion during laser penetration. Its two side edges can be designed with flanges or grooves corresponding to the snap-fit ​​grooves 40 formed on the cover 101 and base 102, allowing the arc-shaped plate to be precisely snapped and fixed onto the housing 10. When the laser generator rotates within the mounting cavity 2021 in the main body 202 along with the operation unit 201, the laser beam emitted by the light-emitting part of the laser generator will always pass through the quarter-circle arc-shaped plate, thereby achieving continuous and precise adjustment of the laser direction within the range of 0° to 90°.

[0087] Through the above technical solution, the curved plate structure used in the light-transmitting part 30 is specifically defined as a quarter-circle arc plate, effectively solving the problems of insufficiently specific and optimized curved plate structure shape in the prior art, resulting in inaccurate laser projection angle coverage and insufficient structural compactness. This precise arc design ensures that the laser projection angle is perfectly matched with the rotation angle range of the rotating component 20, thereby providing a precise laser angle coverage range and avoiding laser direction deviation. In addition, the compact design of the arc plate allows it to fit tightly with the snap-fit ​​grooves 40 on the cover 101 and the base 102, enhancing installation stability and optimizing the overall structural compactness of the laser adjustment mechanism, thus improving the flexibility and accuracy of laser adjustment. Example

[0088] In some of the solutions described above in this application, a laser adjustment mechanism is proposed to adjust the angle between the laser direction and the length direction of the housing 10. This mechanism can be integrated into the level body, as detailed below: In response, this application proposes a laser-adjustable level, which includes a level body 50 and a laser adjustment mechanism disposed at at least one end of the level body, wherein the housing 10 is provided with a connecting part 108 connected to the level body.

[0089] The spirit level body is the main tool for measuring horizontality or verticality, providing a basic measurement reference and support structure. This spirit level body can be made of various materials and structural forms; for example, it can be a profile made of aluminum alloy, plastic, or composite materials. It can integrate a traditional bubble level or be equipped with a digital display module for more precise electronic measurement. The laser adjustment mechanism is a device according to the above scheme. Its core function is to adjust the angle formed between the laser direction and the length direction of the housing 10, thereby achieving multi-angle laser projection. This mechanism typically includes components such as the housing 10, a rotating component 20, a laser generator, and a light-transmitting part 30. Its specific structure and working principle have been described in detail in the above scheme. The connecting part 108 is a structure used to mechanically connect the housing 10 of the laser adjustment mechanism to the spirit level body. The connecting part 108 can be implemented in various ways. For example, it can adopt a threaded connection structure to firmly fix the housing 10 of the laser adjustment mechanism to the level body with screws; it can also adopt a snap-fit ​​connection structure to realize the quick installation and disassembly of the laser adjustment mechanism; or it can adopt a dovetail groove connection to provide a stable sliding or fixed connection to ensure the stability and reliability of the connection.

[0090] The solution of this application integrates the laser adjustment mechanism with the level body and uses the connecting part 108 to ensure a stable connection between the two, thereby forming a fully functional and compact laser adjustable level. Specifically, the level body, as the foundation of the entire device, provides traditional horizontal or vertical measurement functions and a stable support structure. The laser adjustment mechanism, utilizing its unique adjustable angle characteristics, can flexibly change the projection direction of the laser according to actual needs, allowing the laser to be emitted from the light-transmitting part 30 and pointed at any desired angle. The connecting part 108 plays a crucial role in this process, tightly and firmly connecting the housing 10 of the laser adjustment mechanism with the level body, avoiding problems such as decreased laser projection accuracy or structural loosening caused by unstable connection. This integrated design allows the laser emitted by the laser adjustment mechanism to be precisely adjusted and projected with the level body as a reference, ensuring the accuracy of the measurement results. Overall, this solution cleverly combines the precise pointing capability of laser with the measurement reference of a level, forming a collaborative system that not only solves the limitations of traditional levels in long-distance, multi-angle measurements, but also overcomes the shortcomings of existing laser levels in terms of structural compactness and angular flexibility.

[0091] In one specific implementation, the spirit level body can be made of high-strength aluminum alloy profile, integrating a high-precision bubble level, and having a pre-installed installation interface at one end. The laser adjustment mechanism has a rotating component 20 inside its housing 10, and a laser generator inside the rotating component 20. The laser generator is configured to rotate with the rotating component 20 and adjust the angle formed between the laser direction and the length direction of the housing 10. A light-transmitting part 30 is also provided on the housing 10, from which the laser beam can be emitted. To achieve a stable connection between the laser adjustment mechanism and the spirit level body, a raised dovetail groove structure as a connecting part 108 can be provided on the side of the housing 10. Correspondingly, a dovetail groove fitting structure that mates with this dovetail groove structure can be provided at the end of the spirit level body. In actual use, by sliding the dovetail groove structure on the laser adjustment mechanism housing 10 into the dovetail groove fitting structure of the spirit level body, and further locking it from the side of the spirit level body using fastening screws, a stable and precise connection between the laser adjustment mechanism and the spirit level body can be achieved.

[0092] By tightly integrating the laser adjustment mechanism with the level body using the above technical solution, the instability problems caused by traditional external or loose connection methods are avoided, thus ensuring the accuracy and stability of laser projection. The connecting part 108 allows the laser adjustment mechanism to be firmly fixed to the level body, forming a compact integrated structure that effectively reduces the overall size and improves the portability of the level. This integrated design improves the structural strength and reliability of the entire level, enabling users to obtain accurate and reliable measurement results in various measurement scenarios. Combined with the multi-angle projection capability of the laser adjustment mechanism itself, this level not only possesses the measurement functions of a traditional level but also provides flexible and adjustable laser indication, greatly expanding its application range and practicality.
