DETAILED DESCRIPTION

[0026] In order to enable the personnel in the technical field to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the personnel in the art without creative labor should belong to the scope of protection of the present application.

[0027] Unless otherwise explicitly indicated, in the entire specification and claims, the term "comprise" or its variants such as "contain" or "include" and the like will be understood to include the stated element or component, without excluding other elements or components.

[0028] The conventional laser leveling instrument mainly relies on horizontal placement, and performs horizontal laser fan scanning through a laser rotating head 1, and is widely used for horizontal plane positioning. However, when the construction demand turns to vertical direction positioning, the existing device cannot directly generate a vertical laser line, and must be manually adjusted in the placement angle of the instrument, that is, the device is turned from a horizontal state to a vertical state to realize this. This operation process is not only cumbersome and time-consuming, but also easy to introduce measurement errors in the frequent switching process, which reduces the measurement accuracy and work efficiency.

[0029] In addition, the existing laser leveling instrument usually only supports a fixed function mode in design, and lacks a flexible function switching mechanism. This leads to the fact that in a complex construction environment requiring simultaneous reference to horizontal and vertical lines, the user has to rely on multiple devices or additional operation steps, further increasing the construction cost and operation difficulty. At the same time, the switching of the device between different modes lacks convenience, affecting the overall use experience and work smoothness.

[0030] Based on the above problems, the present application provides a technical solution capable of realizing rapid switching of horizontal laser plane and vertical laser line at a fixed position. The core idea of the present application is to integrate a switchable function component in the laser leveling instrument to realize rapid conversion of horizontal laser plane and 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 can convert the horizontal laser beam into a vertical laser plane projection. The optical component can maintain the stable emission of the horizontal laser without interference in the horizontal laser fan scanning mode, and when a vertical laser line needs to be generated, it is adjusted to the corresponding position through simple mechanical or electronic operation, so as to realize rapid conversion of the laser direction.

[0032] This design idea avoids the cumbersome operation of manually adjusting the placement angle of the traditional device when switching modes, and through the integrated function module, the utility model discloses a single device realizes multi-directional laser projection, satisfies the diversified measuring demand in complex construction environment.

[0033] Please refer to Figure 1 The laser rotating head 1 of the utility model includes rotating mechanism 11 and laser emitter 12, and rotating mechanism 11 can rotate along the horizontal direction, and laser emitter 12 is installed on rotating mechanism 11, and laser emitter 12 can emit laser beams along the horizontal direction.The conical mirror assembly 2 includes support 21 and conical lens 22, support 21 is movably arranged on rotating mechanism 11, and conical lens 22 is fixed on support 21, and conical lens 22 can be switched between the first position and the second position under the driving of support 21.

[0034] When conical lens 22 is at the first position, the laser beams emitted by laser emitter 12 can irradiate on the cone top of conical lens 22, and the laser beams emitted by laser emitter 12 are coaxial with conical lens 22.When conical lens 22 is at the second position, conical lens 22 can avoid the laser beams emitted by laser emitter 12.

[0035] The laser rotating head 1 is one of the core components of the laser leveling instrument, and it includes rotating mechanism 11 and laser emitter 12.The rotating mechanism 11 is used to drive laser emitter 12 to rotate along the horizontal direction, so that laser emitter 12 can emit laser beams in the horizontal plane to generate continuous horizontal fan-shaped laser surface.Laser emitter 12 is installed on rotating mechanism 11, which ensures that the laser beams emitted by it always remain stable and synchronous with the horizontal rotation movement, providing basic support for accurate positioning and measurement.

[0036] The conical mirror assembly 2 is part of the device to realize the function of vertical laser line, which is composed of support 21 and conical lens 22.Support 21 is movably connected to rotating mechanism 11, and its main function is to provide adjustable support for conical lens 22, so that conical lens 22 can be switched between the first position and the second position.When conical lens 22 is at the first position, the laser beams emitted by laser emitter 12 directly irradiate on the cone top of conical lens 22, and by using the reflection characteristics of conical lens 22, the point laser beams are converted into vertical ring-shaped laser surface, thereby generating a vertical laser line on the working plane.The design of conical lens 22 is optimized, and its cone top position is coaxial with the laser beam, which ensures the accuracy of laser reflection and the stability of vertical laser line.

[0037] It is noted that the key to the cone lens 22 to convert the laser beam from a point to a ring-shaped plane laser lies in its unique geometry and optical reflection characteristics. The laser transmitter 12 emits a point laser beam (or a highly collimated laser beam similar to a point light source) in a horizontal state. When the cone lens 22 is in the first position, the point laser beam parallel to the horizontal plane directly irradiates the cone top position of the cone lens 22, so that the spot of the incident laser beam is concentrated on the cone top. Since the laser beam propagates in the horizontal direction at this time, the incident point is coaxial with the axis of the cone lens 22, that is, the propagation direction of the laser beam coincides with the central axis of the cone lens 22.

[0038] The cone lens 22 is essentially a reflecting surface with a specific cone angle (e.g., set to 90°). From the law of optical reflection, when light rays are incident on a mirror surface, the reflected light rays will follow the basic law that the incident angle is equal to the reflection angle. For a common plane mirror, the reflection of a point light source is still point-shaped, but the cone lens 22 is a three-dimensional conical surface that is symmetrical around the axis. When a point light source is located on the central axis of the cone mirror and emits light rays to irradiate the conical surface, the light rays will be reflected with the normal direction of the conical surface as the reference. Since the conical surface is composed of countless micro-mirror elements with the same inclination angle and symmetrical distribution around the axis, the light rays emitted by the incident point light source will be dispersed in a ring-shaped manner in all directions after reflection on the conical surface.

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

[0040] The cone angle of the cone lens 22 is preferably 90°. The size of the cone angle directly affects the reflection direction and scattering range of the light rays, and a 90° cone angle can achieve the ideal vertical reflection effect in the optical path, causing the light rays to propagate in the vertical direction and generate a stable and clear vertical light ring. From the perspective of optical efficiency, a 90° cone angle can maximize the avoidance of light energy loss. The angle of the cone top determines the uniformity of the reflection path, and a too large cone angle may cause the reflection direction of part of the light rays to deviate from the vertical plane, thereby affecting the clarity of the vertical laser line; and a too small cone angle may cause the reflection path to be too close, resulting in a too narrow or uneven light ring that cannot cover enough construction area.

[0041] When the conical lens 22 is in the second position, the support 21 moves the conical lens 22 to an area that avoids the laser beam through mechanical or electronic control, so that the laser beam emitted by the laser emitter 12 directly expands along the horizontal direction without being affected by the conical lens 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 during function switching.

[0042] In an exemplary embodiment, referring to Figure 1 and Figure 2 The rotating mechanism 11 includes a base 111, a wheel disc 112, and a drive motor 113. The wheel disc 112 is rotatably arranged on the base 111, and the laser emitter 12 is fixed to the wheel disc 112. The wheel disc 112 is in transmission connection with the output shaft of the drive motor 113, and the drive motor 113 can drive the wheel disc 112 to rotate in the horizontal direction.

[0043] The base 111 is a supporting component of the rotating mechanism 11 and is the basis of the stability of the entire device. It needs to have sufficient strength and rigidity to bear the weight of the wheel disc 112, the laser emitter 12, and other components, while ensuring that no significant vibration or deviation occurs during device operation. The shape and material of the base 111 can be designed according to needs to adapt to different construction environments, for example, lighter materials may be needed for indoor construction, while in outdoor construction, more attention may be paid to the wind resistance and durability of the base 111.

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

[0045] The driving motor 113 is the power source of the rotating mechanism 11, and transmits the rotating power to the wheel disc 112 through the output shaft. In order to meet the requirement of smoothness of laser projection in the working scene, the driving motor 113 is preferably provided with high-precision rotating speed control capability. The connection mode of the driving motor 113 and the wheel disc 112 can adopt the form of belt transmission, flexible coupling or gear transmission, which can not only ensure the reliability of power transmission, but also can absorb the vibration and impact in the rotating process to a certain extent.

[0046] Specifically, the first pulley 114 is fixed on the wheel disc 112, and the output shaft of the driving motor 113 is fixed with the second pulley 115, and the first pulley 114 and the second pulley 115 are drivingly connected through the 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 rotating power, the first pulley 114 can be fixedly installed on the upper part of the wheel disc 112. The diameter of the first pulley 114 is large, which can effectively amplify the torque output of the driving motor 113 through the adjustment of the transmission ratio, so as to ensure that the rotation of the wheel disc 112 is more stable and reliable while keeping the lower motor power.

[0048] The driving motor 113 as the power source is provided with the second pulley 115 on the output shaft. The diameter of the second pulley 115 is small, and compared with the size difference of the first pulley 114, this design forms a transmission ratio structure of torque increase and speed reduction. Specifically, the small-diameter second pulley 115 will quickly drive the transmission belt 116 to run when the driving motor 113 rotates, and the transmission belt 116 further drives the large-diameter first pulley 114. Since the circumference of the first pulley 114 is large, its rotating speed is relatively slow compared with the second pulley 115, but the output torque is significantly improved. This design can effectively reduce the difficulty of starting or unstable rotation caused by heavy load of the wheel disc 112, while ensuring the uniformity and measurement accuracy of the laser emitter 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 not only can efficiently transmit power, but also has a certain buffering effect, which can reduce the impact force generated when the motor starts instantaneously or the load changes, thereby prolonging the service life of the transmission system. In addition, the surface of the transmission belt 116 can be designed to match the tooth structure of the two pulleys, so as to ensure the stability and efficiency of power transmission, and avoid slipping or mispositioning.

[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 rotationally connected to the rotating mechanism 11, and the mounting plate 212 is fixed to one end of the rotating arm 211, and 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 at the same time, it gives the conical lens 22 the activity ability to switch between the first position and the second position. The rotating arm 211 and the rotating mechanism 11 are rotationally connected, allowing the rotating arm 211 to freely swing around a certain axis. The design of the rotating arm 211 takes into account the mechanical stability and operational convenience, 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 smooth and accurate rotation.

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

[0053] The bracket 21 is rotationally connected to the rotating mechanism 11 through the rotating arm 211, realizing the flexible switching of the conical 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 conical lens 22, so that it can effectively reflect the horizontal laser beam to generate a vertical laser line when it is in the first position; while in the second position, the conical lens 22 is moved to an area away from the laser beam, restoring the function of the horizontal laser plane, which improves the multifunctionality and operational convenience of the laser leveling instrument.

[0054] Specifically, the mounting plate 212 is fixedly connected with a mounting seat 213, and the conical lens 22 is arranged 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 aims to provide a stable fixing platform for the conical lens 22, while ensuring its accurate positioning in the optical function. The mounting plate 212 and the mounting seat 213 form an integral structure through fixed connection.

[0055] The mounting plate 212, as part of the bracket 21, mainly serves as a basic platform for supporting and fixing the conical lens 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 maintains coaxiality with the optical center of the conical lens 22 when it is irradiated, providing a good basis for subsequent optical reflection and laser plane generation.

[0056] The mounting seat 213 is fixedly connected to the through hole area of the mounting plate 212, which further stabilizes the conical lens 22 and reduces the influence of external factors on the positioning of the conical lens 22. The mounting seat 213 can firmly lock the conical lens 22, so that it does not shake or deviate during the operation of the equipment. The conical lens 22 can be fixed to the mounting seat 213 by gluing.

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

[0058] The rotating arm 211 is the main supporting component of the conical lens 22, and its design endows the conical lens 22 with the activity of switching between different working positions. When the conical lens 22 is in the first position, the middle part of the rotating arm 211 contacts the supporting piece 117, and relies on the supporting force provided by the supporting piece 117 in the vertical direction to avoid the rotating arm 211 from falling due to gravity.

[0059] The supporting piece 117 is fixed to the wheel disc 112 and is a supporting component for stable positioning of the rotating arm 211. The supporting piece 117 not only provides physical support in the vertical direction, but also integrates a magnetic attraction structure therein to further improve the fixing effect of the conical lens 22 in the first position. The second magnetic attraction piece 118 provided on the supporting piece 117 corresponds to the first magnetic attraction piece 214 on the rotating arm 211, and realizes additional locking of the rotating arm 211 through magnetic force. This magnetic attraction 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 is always coaxial with the path of the laser beam.

[0060] The magnetic force between the first magnetic attraction piece 214 and the second magnetic attraction piece 118 is preferably designed to provide sufficient adsorption force to fix the rotating arm 211, and not to hinder the flexible switching of the rotating arm 211. This magnetic attraction connection method avoids the complex operation or component wear problems that may be caused by traditional mechanical locking, and still maintains stable fixing effect in the case of equipment vibration, impact or long time operation.

[0061] The conical lens 22 needs high stability and precision when in the first position, and the rotating arm 211 as a movable component 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 support 21 structure is optimized, which is more in line with the demand of the laser leveling instrument for high-precision positioning.

[0062] Further, the rotating arm 211 is provided with a third magnetic attraction piece 215, and the rotating mechanism 11 is provided with a fourth magnetic attraction piece 119 corresponding to the third magnetic attraction piece 215. When the conical lens 22 is in the second position, the third magnetic attraction piece 215 and the fourth magnetic attraction piece 119 are magnetically attracted to each other, so that the conical lens 22 is kept in the second position.

[0063] The rotating arm 211 as a support and switching component of the conical lens 22 not only needs to connect the conical lens 22 and the rotating mechanism 11, but also needs to move flexibly between different positions and keep stable. When the conical lens 22 is in the second position, i.e. the non-working state, the third magnetic attraction piece 215 on the rotating arm 211 plays a positioning role. The third magnetic attraction piece 215 is designed to correspond to the fourth magnetic attraction piece 119 on the rotating mechanism 11, and the rotating arm 211 is stably fixed in the non-working position by magnetic adsorption.

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

[0065] The rack 3 as the support base of the whole device mainly provides a stable mounting platform and provides rigid support for the operation of the lifting mechanism 4. The rack 3 is preferably good in anti-vibration and anti-tilting performance, so as to ensure that the lifting mechanism 4 and the rotating mechanism 11 keep stable during movement and will not affect the measurement accuracy due to external force or vibration.

[0066] The lifting mechanism 4 is a structure for realizing the vertical movement of the rotating mechanism 11, and the core components thereof include a lifting rod and a driving device. The lifting rod is installed on the rack 3 along the vertical direction, and the bottom thereof is connected with the driving device. Through the power output of the driving device, the lifting rod can move up and down stably. The base 111 of the rotating mechanism 11 is fixedly connected with the lifting rod, and this design enables the whole rotating mechanism 11 to realize height adjustment with the movement of the lifting rod.

[0067] In summary, the laser leveling instrument provided by the utility model realizes the quick switching of the horizontal laser plane and the vertical laser line through the cooperative work of the laser rotating head and the conical lens assembly, without the need of adjusting the placing angle of the equipment, greatly simplifies the operation process, and can meet the measurement demand in multiple directions.
