Description

Technical Field

[0002] Laser levelers are widely used in construction, interior decoration and precision measurement. They can provide high-precision laser reference lines or surfaces to assist in horizontal and vertical positioning. However, most laser levelers on the market currently have a single functional design and are difficult to meet the needs of multiple laser forms in complex construction environments.

[0003] Traditional laser levelers are usually placed horizontally to achieve horizontal laser fan-sweep projection, and are mainly used for horizontal plane positioning. However, when vertical laser line projection is required, existing equipment cannot directly generate vertical line functions, and the instrument placement direction must be manually adjusted, that is, the device must be switched from horizontal to vertical. This process is not only cumbersome to operate, but also difficult to ensure adjustment accuracy. Especially in scenarios where horizontal and vertical lines need to be switched frequently, traditional equipment is particularly inconvenient.

[0004] In addition, existing laser levelers usually do not have a quick switching function when placed horizontally. During use, operators need to constantly adjust the position and direction of the device and manually calibrate to achieve laser projection in different directions. This not only increases the workload, but also easily leads to measurement error accumulation due to multiple adjustments, affecting the final positioning accuracy.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0028] Traditional laser levelers mainly rely on horizontal placement and use a laser rotating head 1 to perform horizontal laser fan scanning, which is widely used in horizontal plane positioning. However, when the construction demand turns to vertical positioning, the existing equipment cannot directly generate vertical laser lines, and it is necessary to manually adjust the placement angle of the instrument, that is, to turn the device from a horizontal state to a vertical state. This operation process is not only cumbersome and time-consuming, but also easily introduces measurement errors during frequent switching, reducing the accuracy of the measurement and work efficiency.

[0029] In addition, existing laser levelers are usually designed to support only fixed functional modes and lack a flexible function switching mechanism. This results in users having to rely on multiple devices or additional operating steps in complex construction environments that require reference to both horizontal and vertical lines, further increasing construction costs and operating difficulties. At the same time, the lack of convenience in switching between different modes affects the overall user experience and work fluency.

[0030] Based on the above problems, the present invention proposes a technical solution that can realize the rapid switching between the horizontal laser plane and the vertical laser line in a fixed position. The core idea of ​​the present invention is to integrate switchable functional components in the laser leveling instrument to realize the rapid conversion between the horizontal laser plane and the vertical laser line, so that the device can efficiently generate laser reference lines in different directions.

[0031] Specifically, by adding an adjustable optical component to the laser rotating head, it is possible to convert the horizontal laser beam into a vertical laser surface projection. The optical component can maintain the stable emission of the horizontal laser without interfering with the horizontal laser fan scanning mode, and when the vertical laser line needs to be generated, it can be adjusted to the corresponding position through simple mechanical or electronic operations, thereby realizing the rapid conversion of the laser direction.

[0032] This design concept avoids the tedious operation of manually adjusting the placement angle of traditional equipment when switching modes. Through integrated functional modules, the present invention realizes multi-directional laser projection in a single device to meet the diverse measurement needs in complex construction environments.

[0033] Please refer to Figure 1 As shown, a laser leveling instrument in an embodiment of the present invention comprises a laser rotating head 1 and an axle assembly 2. The laser rotating head 1 comprises a rotating mechanism 11 and a laser emitter 12. The rotating mechanism 11 can rotate in the horizontal direction. The laser emitter 12 is mounted on the rotating mechanism 11, and the laser emitter 12 can emit a laser beam in the horizontal direction. The axle assembly 2 comprises a bracket 21 and an axle lens 22. The bracket 21 is movably arranged on the rotating mechanism 11. The axle lens 22 is fixed on the bracket 21. The axle lens 22 can switch between a first position and a second position under the drive of the bracket 21.

[0034] When the axicon 22 is in the first position, the laser beam emitted by the laser emitter 12 can be irradiated on the cone top of the axicon 22, and the laser beam emitted by the laser emitter 12 is coaxial with the axicon 22. When the axicon 22 is in the second position, the axicon 22 can avoid the laser beam emitted by the laser emitter 12.

[0035] The laser rotating head 1 is one of the core components of the laser leveler, which includes a rotating mechanism 11 and a laser emitter 12. The function of the rotating mechanism 11 is to drive the laser emitter 12 to rotate in the horizontal direction, so that the laser emitter 12 can emit a laser beam in the horizontal plane to generate a continuous horizontal fan-shaped laser surface. The laser emitter 12 is installed on the rotating mechanism 11 to ensure that the laser beam it emits always remains stable and synchronized with the horizontal rotation movement, providing basic support for precise positioning and measurement.

[0036] The conical lens assembly 2 is the part of the device that realizes the vertical laser line function, and is composed of a bracket 21 and a conical lens 22. The bracket 21 is movably connected to the rotating mechanism 11, and its main function is to provide adjustable support for the conical lens 22, so that the conical lens 22 can switch between the first position and the second position. When the conical lens 22 is in the first position, the laser beam emitted by the laser transmitter 12 directly irradiates the cone top of the conical lens 22, and utilizes the reflection characteristics of the conical lens 22 to convert the point laser beam into a vertical annular laser surface, thereby generating a vertical laser line on the working plane. The design of the conical lens 22 is optimized, and its cone top position is coaxial with the laser beam, ensuring the accuracy of laser reflection and the stability of the vertical laser line.

[0037] It should be noted that the key to the conversion of the laser beam from a point to an annular surface by the conical lens 22 lies in its unique geometric shape and optical reflection characteristics. The laser emitter 12 emits a beam of point laser (or a highly collimated laser beam similar to a point light source) in a horizontal state. When the conical lens 22 is in the first position, this beam of point laser parallel to the horizontal plane directly irradiates the top of the cone of the conical lens 22, so that the light spot of the incident laser is just concentrated on the top of the cone. Since the laser beam propagates in the horizontal direction at this time, the incident point is coaxial with the axis of the conical lens 22, that is, the propagation direction of the laser beam coincides with the central axis of the conical lens 22.

[0038] The conical lens 22 is essentially a reflective surface with a specific cone angle (such as set to 90°). From the perspective of optical reflection rules, when light is incident on the mirror surface, the reflected light will obey the basic law of "the angle of incidence equals the angle of reflection". For an ordinary plane mirror, the reflection of a point light source is still point-shaped, but the conical lens 22 is a three-dimensional conical surface symmetrical around an axis. When the point light source is located on the central axis of the conical mirror and emits light to illuminate the conical surface, these light rays will be reflected based on the normal direction of the conical surface. Since the conical surface is composed of countless tiny mirror elements with the same inclination angle and symmetrically distributed around the axis, the light emitted by the incident point light source will diverge in a ring-shaped manner in all directions after being reflected on the conical surface.

[0039] More specifically, when the horizontal laser beam converges into a point at the top of the cone, the tiny offset light rays emitted by the point light source in the upward, downward, left and right directions hit different positions of the cone surface. Each cone surface position has the same inclination angle and symmetrical distribution around the axis, which makes the light beam originally concentrated at one point be evenly expanded into an annular light band distributed around the axis after reflection. Due to the geometric symmetry of the design of the conical lens 22, all reflected light eventually forms a vertical hollow conical light band in space, that is, an annular surface laser. Unlike simple point reflection, the light at this time is no longer concentrated at one point, but is evenly distributed to form a closed light ring surface. If this annular light surface is projected onto a vertical working plane (such as a wall), the cross-section of the annular surface laser on the vertical plane is a vertical laser line.

[0040] The cone angle of the conical lens 22 is preferably 90°. The size of the cone angle directly affects the reflection direction and scattering range of the light, and a 90° cone angle can achieve an ideal vertical reflection effect in the optical path, allowing the light to propagate in the vertical direction, generating a stable and clear vertical halo. From the perspective of optical efficiency, a 90° cone angle can avoid the loss of light energy to the greatest extent. The angle of the cone top determines the uniformity of the reflection path. A cone angle that is too large may cause the reflection direction of some light to deviate from the vertical plane, thereby affecting the clarity of the vertical laser line; and a cone angle that is too small may cause the reflection path to be too close, resulting in the halo being too narrow or uneven, and unable to cover enough construction area.

[0041] When the axicon 22 is in the second position, the bracket 21 moves the axicon 22 to an area away from the laser beam through mechanical or electronic control, so that the laser beam emitted by the laser emitter 12 directly expands in the horizontal direction without being affected by the axicon 22, thereby restoring the function of the horizontal laser plane. Such a design not only realizes efficient switching of horizontal and vertical functions, but also avoids mechanical errors that may be introduced by the device when switching functions.

[0042] In an exemplary embodiment, please refer to Figure 1 and Figure 2 As shown, the rotating mechanism 11 includes a base 111, a wheel 112 and a driving motor 113. The wheel 112 is rotatably arranged on the base 111, the laser emitter 12 is fixed on the wheel 112, and the wheel 112 is drivingly connected to the output shaft of the driving motor 113. The driving motor 113 can drive the wheel 112 to rotate in the horizontal direction.

[0043] The base 111, as the supporting component of the rotating mechanism 11, is the basis of the stability of the entire device. Its design must have sufficient strength and rigidity to bear the weight of the wheel 112, the laser transmitter 12 and other components, while ensuring that no obvious vibration or offset occurs during the operation of the equipment. The shape and material of the base 111 can be designed as needed to meet the needs of different construction environments. For example, lighter materials may be required in indoor construction, while more attention may be paid to the wind resistance and durability of the base 111 in outdoor construction.

[0044] The wheel disc 112 is a key component for realizing horizontal rotation in the rotating mechanism 11. Its design takes into account both the lightweight structure and the stability during the rotation process. The rotation mode of the wheel disc 112 provides it with the physical conditions for realizing horizontal laser surface scanning. The wheel disc 112 can be mounted on the base 111 through precision bearings to ensure low friction and high stability during the rotation process. The outer edge of the wheel disc 112 and the output shaft of the drive motor 113 can be connected through a transmission structure. The power provided by the drive motor 113 acts on the wheel disc 112 through the transmission structure, so that it can realize uniform and continuous horizontal rotation. At the same time, the upper surface of the wheel disc 112 provides an installation platform for the laser emitter 12, ensuring that the laser emitter 12 always keeps synchronization with its rotational motion, providing a basis for the formation of a horizontal laser surface.

[0045] The drive motor 113 is the power source of the rotating mechanism 11, and transmits the rotational power to the wheel disc 112 through its output shaft. In order to meet the requirements for laser projection smoothness in the working scene, the drive motor 113 preferably has high-precision speed control capability. The connection between the drive motor 113 and the wheel disc 112 can be in the form of belt drive, flexible coupling or gear drive, which can not only ensure the reliability of power transmission, but also absorb vibration and impact during rotation to a certain extent.

[0046] Specifically, a first pulley 114 is fixed on the wheel disc 112, a second pulley 115 is fixed on the output shaft of the driving motor 113, and the first pulley 114 and the second pulley 115 are connected by a transmission belt 116. The diameter of the first pulley 114 is preferably larger than that of the second pulley 115.

[0047] In order to enable the wheel disc 112 to obtain stable rotational power, a first pulley 114 can be fixedly installed on its upper part. The first pulley 114 has a larger diameter, and this design can effectively amplify the torque output of the drive motor 113 by adjusting the transmission ratio, thereby ensuring that the rotation of the wheel disc 112 is more stable and reliable while maintaining a lower motor power.

[0048] The driving motor 113 serves as a power source, and a second pulley 115 is installed on its output shaft. The diameter of the second pulley 115 is smaller, and compared with the size difference of the first pulley 114, this design forms a transmission ratio structure of increasing torque and reducing speed. Specifically, the second pulley 115 with a small diameter will quickly drive the transmission belt 116 to run when the driving motor 113 rotates, and the transmission belt 116 further drives the first pulley 114 with a large diameter. Since the circumference of the first pulley 114 is larger, its rotation speed is relatively slower than that of the second pulley 115, but the output torque is significantly improved. This design can effectively reduce the difficulty in starting or unstable rotation caused by the heavy load of the wheel 112, while ensuring the uniformity and measurement accuracy of the laser transmitter 12 during horizontal rotation.

[0049] The transmission belt 116 is an intermediate component connecting the first pulley 114 and the second pulley 115, and has a certain flexibility. The flexible transmission belt 116 can not only efficiently transmit power, but also has a certain buffering effect, which can reduce the impact force generated when the motor is instantly started or the load changes, thereby extending the service life of the transmission system. In addition, the surface of the transmission belt 116 can be frictionally designed to match the tooth structure of the two pulleys to ensure the stability and efficiency of power transmission and avoid slippage or misalignment.

[0050] In an exemplary embodiment, please refer to Figure 1 and Figure 3As shown, the bracket 21 includes a rotating arm 211 and a mounting plate 212 . The rotating arm 211 is rotatably connected to the rotating mechanism 11 . The mounting plate 212 is fixed to one end of the rotating arm 211 . The mounting plate 212 is provided with a mounting through hole 216 for accommodating the conical lens 22 .

[0051] The main function of the rotating arm 211 is to connect the mounting plate 212 and the conical lens 22 to the rotating mechanism 11, and to give the conical lens 22 the ability to switch between the first position and the second position. The rotating arm 211 and the rotating mechanism 11 are designed with a rotation connection, allowing the rotating arm 211 to swing freely around a specific axis. The design of the rotating arm 211 takes into account mechanical stability and ease of operation, and can be made of high-strength materials to withstand the reaction force and vibration generated by the conical lens 22 during operation, while ensuring the smoothness and accuracy of the rotation process.

[0052] The mounting plate 212 is fixed to one end of the rotating arm 211 and is a component for supporting and fixing the axle lens 22. A mounting through hole 216 is provided on the mounting plate 212 for accommodating and fixing the position of the axle lens 22. The size and shape of the mounting through hole 216 are designed to avoid interference with the reflective characteristics of the axle lens 22. The rigid connection between the mounting plate 212 and the rotating arm 211 provides support and ensures that the optical center of the axle lens 22 remains coaxial with the laser beam when it is in the first position.

[0053] The bracket 21 is connected to the rotating mechanism 11 by rotation through the rotating arm 211, so as to realize the flexible switching of the axle lens 22 between the first position and the second position. When the rotating arm 211 rotates, the mounting plate 212 can accurately adjust the position of the axle lens 22, so that it can effectively reflect the horizontal laser beam and generate a vertical laser line in the first position; while in the second position, the axle lens 22 is moved to an area avoiding the laser beam, and the function of the horizontal laser plane is restored. This design improves the versatility and ease of operation of the laser leveler.

[0054] Specifically, the mounting plate 212 is fixedly connected with the mounting seat 213, and the axon 22 is disposed in the mounting through hole 216 and fixedly connected with the mounting seat 213. The structural design of the mounting plate 212 and the mounting seat 213 is intended to provide a stable fixing platform for the axon 22 while ensuring its precise positioning in the optical function. The mounting plate 212 forms an integral structure with the mounting seat 213 by means of a fixed connection.

[0055] The mounting plate 212 is a part of the bracket 21, and its main function is to provide a basic platform for supporting and fixing the axicon 22. The position of the mounting through hole 216 is strictly aligned with the emission path of the laser beam, ensuring that the laser beam remains coaxial with the optical center of the axicon 22 when irradiating the axicon 22, providing a good foundation for subsequent optical reflection and the generation of the laser surface.

[0056] The mounting seat 213 is fixedly connected to the through hole area of ​​the mounting plate 212, and its function is to further stabilize the axle lens 22 and reduce the influence of external factors on the positioning of the axle lens 22. The mounting seat 213 can firmly lock the axle lens 22 so that it does not shake or shift during the operation of the device. The axle lens 22 can be fixed to the mounting seat 213 by gluing.

[0057] Furthermore, a first magnetic member 214 is provided on the rotating arm 211, a support member 117 is provided on the rotating mechanism 11, and a second magnetic member 118 corresponding to the first magnetic member 214 is provided on the support member 117. When the axle lens 22 is in the first position, the rotating arm 211 can be supported on the support member 117, and the first magnetic member 214 and the second magnetic member 118 are magnetically attracted to each other, so that the axle lens 22 is kept in the first position.

[0058] The rotating arm 211 is the main supporting component of the axicon 22, and its design endows the axicon 22 with the mobility to switch between different working positions. When the axicon 22 is in the first position, the middle of the rotating arm 211 contacts the support member 117, and the supporting force provided by the support member 117 in the vertical direction prevents the rotating arm 211 from falling due to gravity.

[0059] The support member 117 is fixed to the wheel disc 112 and is a support component for the stable positioning of the rotating arm 211. The support member 117 not only provides physical support in the vertical direction, but also integrates a magnetic structure therein to further improve the fixing effect of the conical lens 22 in the first position. The second magnetic member 118 provided on the support member 117 corresponds to the first magnetic member 214 on the rotating arm 211, and realizes additional locking of the rotating arm 211 through magnetic force. This magnetic design can effectively prevent slight displacement of the rotating arm 211 caused by vibration or operation, and further ensures that the working position of the conical lens 22 always remains coaxial with the path of the laser beam.

[0060] The magnetic strength between the first magnetic member 214 and the second magnetic member 118 is preferably designed to provide sufficient adsorption force to fix the rotating arm 211 without causing excessive obstruction to the flexible switching of the rotating arm 211. This magnetic connection method avoids the complicated operation or component wear problems that may be caused by traditional mechanical locking, and can still maintain a stable fixing effect under the condition of device vibration, impact or long-term operation.

[0061] The conical lens 22 needs to be highly stable and accurate in the first position, and the rotating arm 211, as a movable part, is difficult to completely resist the influence of gravity and vibration through simple mechanical support. By introducing magnetic attraction, not only the stability of the system is improved, but also the overall design of the bracket 21 structure is optimized, making it more in line with the laser leveling instrument's requirements for high-precision positioning.

[0062] Furthermore, the rotating arm 211 is provided with a third magnetic member 215, and the rotating mechanism 11 is provided with a fourth magnetic member 119 corresponding to the third magnetic member 215. When the axon 22 is in the second position, the third magnetic member 215 and the fourth magnetic member 119 are magnetically attracted to each other, so that the axon 22 remains in the second position.

[0063] The rotating arm 211 serves as a support and switching component for the conical lens 22. Its function is not only to connect the conical lens 22 to the rotating mechanism 11, but also to move flexibly between different positions and maintain stability. When the conical lens 22 is in the second position, that is, the non-working state, the third magnetic attraction member 215 on the rotating arm 211 plays a positioning role. The third magnetic attraction member 215 is designed to correspond to the fourth magnetic attraction member 119 on the rotating mechanism 11, and the rotating arm 211 is firmly fixed in the non-working position by magnetic adsorption.

[0064] In an exemplary embodiment, the laser leveling instrument further includes a frame 3 , on which a lifting mechanism 4 is provided, and the rotating mechanism 11 is installed on the lifting mechanism 4 , so that the rotating mechanism 11 can be lifted and lowered in a vertical direction under the drive of the lifting mechanism 4 .

[0065] The frame 3 serves as the supporting base of the entire device, and its main function is to provide a stable installation platform and provide rigid support for the operation of the lifting mechanism 4. The frame 3 preferably has good anti-vibration and anti-tilt performance to ensure that the lifting mechanism 4 and the rotating mechanism 11 remain stable during movement, and the measurement accuracy will not be affected by external force or vibration.

[0066] The lifting mechanism 4 is a structure for realizing the vertical movement of the rotating mechanism 11, and its core components include a lifting rod and a driving device. The lifting rod is installed on the frame 3 in the vertical direction, and its bottom is connected to the driving device. Through the power output of the driving device, the lifting rod can move up and down smoothly. The base 111 of the rotating mechanism 11 is fixedly connected to the lifting rod. This design enables the entire rotating mechanism 11 to achieve height adjustment with the movement of the lifting rod.

[0067] In summary, the laser leveling instrument provided by the present invention realizes rapid switching between the horizontal laser plane and the vertical laser line through the coordinated work of the laser rotating head and the conical mirror assembly, without adjusting the device placement angle, greatly simplifies the operation process, and can meet multi-directional measurement needs.
