Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically a leveling instrument. Background Technology
[0002] Laser levels, as key leveling tools in construction, decoration, and civil engineering, work by using a rotating laser to generate visible horizontal or vertical reference lines, thus forming a reference surface. These reference lines or surfaces play a crucial guiding role in leveling and straightening operations during construction, effectively improving construction efficiency and quality, and ensuring accuracy. Currently, rotary laser levels are among the most widely used types due to their comprehensive functions and wide coverage. They can provide a 360° horizontal reference ring and usually also include a vertical laser to meet the needs of different construction scenarios.
[0003] Laser leveling instruments can be placed flat or on their side. When placed on their side, the encoder module needs to print a bottom alignment point, which is then matched with marked points on the ground for positioning. However, existing laser leveling instruments capable of generating clear bottom alignment points require a costly encoder with complex algorithms. Common laser leveling instruments using low-cost mechanisms struggle to directly generate bottom alignment points, necessitating complex adjustments by workers during operation. This increases the difficulty and time cost of construction, negatively impacting efficiency and accuracy.
[0004] Based on this, a leveling device is now provided that can eliminate the drawbacks of existing devices. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] In the description of this application, it should be understood that the terms "length", "width", "horizontal", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0028] This application provides a leveling device, such as Figure 1As shown, the instrument includes an instrument body 1. One end of the instrument body 1 is provided with a laser head 2 that can rotate 360° to emit laser light. Multiple light-transmitting windows 4 are provided on the outside of the laser head 2. A first plane arrow 3 and a second plane arrow 7 that are perpendicular to each other are provided on the side of the instrument body 1 near the laser head 2.
[0029] Understandably, when the leveling device is placed horizontally, its core function is to project a horizontal line in two perpendicularly intersecting planes, such as a first plane and a second plane that are perpendicular to each other. The first plane is perpendicular to the direction of arrow 3 on the first plane marked on the instrument body 1, and the second plane is perpendicular to the direction of arrow 7 on the second plane marked on the instrument body 1, and intersects the first plane precisely at a 90-degree angle. Arrow 3 on the first plane and arrow 7 on the second plane define the absolute directions of these two planes in the room / space when the leveling device is placed horizontally, which means that horizontal line construction can be carried out in these two directions. Specifically, in a rectangular regular room, arrow 3 on the first plane points to the length direction of the room, and arrow 7 on the second plane points to the width direction of the room. The laser head 2 can independently achieve fine adjustment in both directions to adapt to the horizontal line adjustment needs of different heights in the length and width directions of the room.
[0030] Understandably, when the leveling device is placed on its side, workers constructing partitions need to first determine a reference point on the wall and another on the ground to ensure that the laser line scanned by the leveling device is on the plane required for the partition. After positioning using the ground point, the laser head 2 can be remotely controlled or tracked wirelessly using a receiver compatible with the leveling device to fine-tune the horizontal line of the first or second plane mentioned above. It should be noted that the position of the reference point does not change in either of the above two operations, eliminating the need to move the laser leveling device to align with the pre-marked line. This is simple and convenient. If two reference points are taken from the wall instead of the ground, workers would need to move the machine multiple times to align the laser surface with the reference points, making the operation cumbersome and complex.
[0031] In the existing technology, laser leveling instruments that can generate clear bottom alignment points require the use of a high-cost encoder with a complex algorithm to enable the rotating laser head to stop rotating and perform positioning when bottom alignment is achieved. However, common laser leveling instruments that use low-cost mechanisms cannot directly generate bottom alignment points, which requires workers to make complex adjustments during operation, increasing the difficulty and time cost of construction, and also adversely affecting construction efficiency and accuracy.
[0032] Based on the above considerations, this application provides a low-cost solution for generating lower alignment points when the leveling instrument is placed on its side.
[0033] Please refer to Figure 1The instrument body 1, which is pointed to by the arrow 7 on the second plane, is connected to a shielding component 5 for blocking the light-transmitting window 4. The shielding component 5 has a shielding hole 6 for generating the lower alignment point.
[0034] It is understandable that the connection method between the shielding part 5 and the instrument body 1 is not limited; it can be a detachable connection, a non-detachable connection, or an integral molding.
[0035] The shape of the blocking hole 6 of the blocking component 5 is not limited; it can be round, irregular, square, etc.
[0036] In use, the second plane arrow 7 is perpendicular to the ground, then the shield 5 is installed so that the shield 5 blocks the light-transmitting window 4. Then the instrument body 1 is started, and the laser head 2 inside the instrument body 1 rotates to emit laser. Part of the laser is emitted through the shielding hole 6 on the shield 5, forming a downward point on the ground. The structure is simple and effective, reducing the cost of internal mechanism design.
[0037] In some embodiments, such as Figure 1 As shown, the shielding component 5 is rotatably connected to the instrument body 1. The rotatable connection end of the shielding component 5 is provided with a damping structure that enables the shielding component 5 to achieve stepless hovering, making the shielding component 5 rotate more smoothly without any jerking. The damping structure provides sufficient static friction. When the operator applies enough force to overcome the static friction, the shielding component 5 can rotate; however, when the force is removed or is less than the static friction required to maintain the position, the shielding component 5 will immediately and stably remain in the original position, improving the user experience.
[0038] In some embodiments, the free end of the shield 5 is provided with a bent portion 12 that is easy for the user to operate. By contacting the bent portion, the user can rotate the shield 5 more conveniently, thus improving the user experience.
[0039] In some embodiments, the shielding member 5 can switch between a first state of shielding the light-transmitting window 4 and a second state of opening the light-transmitting window 4. The instrument body 1 is provided with a receiving area 13 for accommodating the bent portion 12. In the first state, the bent portion 12 abuts against the instrument body 1. In the second state, the bent portion 12 is disposed in the receiving area 13.
[0040] In some embodiments, the free end of the shielding member 5 is connected to the side wall of the instrument body 1 by a snap-fit connection. When it is necessary to form a lower point, the shielding member 5 is switched from the second state to the first state so that the shielding member 5 blocks the light-transmitting window 4 and is snapped to the side wall of the instrument body 1 by the free end of the shielding member 5. Specifically, the free end of the shielding member 5 is a bent part.
[0041] In some embodiments, the shielding hole 6 is elongated or circular, preferably elongated. In use, part of the laser passes through the shielding hole 6 to form a lower alignment point. Compared with the circular hole design, which requires precise positioning to generate the lower alignment point, otherwise the laser head 2 may not be able to pass through the shielding hole 6, the elongated shielding hole 6 design is simple and effective, avoiding the above-mentioned manufacturing precision problem and is easy to manufacture.
[0042] In some embodiments, such as Figures 1-3 As shown, the instrument body 1 is provided with an operation screen 8 and a first mounting hole 9a. The operation screen 8 is located on the side wall of the instrument body 1 away from the direction indicated by the second plane arrow 7. The first mounting hole 9a is located on the side wall of the instrument body 1 away from the operation screen 8. For example, the first mounting hole 9a can be a threaded hole, which is screwed to a suitable mounting base. When the leveling instrument needs to be placed on its side, the first mounting hole 9a allows the leveling instrument to be placed horizontally on uneven road surfaces using equipment such as a tripod, thereby improving the user's construction accuracy. In addition, the operation screen 8 is located on the side of the instrument body 1 away from the first mounting hole 9a, which facilitates user operation after the leveling instrument is fixed.
[0043] In some embodiments, the instrument body 1 is provided with a second mounting hole 9b, which is located on the side of the instrument body 1 away from the laser head 2, and is used when the leveling instrument is laid flat on a tripod or other suitable mounting structure.
[0044] For example, when using the instrument, the user can operate and set the leveling instrument through the operation screen 8, and install the instrument body 1 on the tripod through the first mounting hole 9a or the second mounting hole 9b.
[0045] In some embodiments, such as Figure 3 As shown, the instrument body 1 has a battery compartment inside, and a battery compartment end cover 10 is provided at one end of the battery compartment. The battery compartment end cover 10 is located at the end of the instrument body 1 away from the laser head 2, and a battery compartment switch 11 is provided on one side of the battery compartment end cover 10.
[0046] In some embodiments, one side of the battery compartment end cover 10 is rotatably connected to the instrument body 1. The rotatable connection end of the battery compartment end cover 10 is provided with a torsion spring. The free end of the battery compartment end cover 10 is connected to the instrument body 1 by a snap fastener. The bottom of the battery compartment is provided with a conical spring as a battery contact point. When the battery needs to be replaced, the battery compartment switch 11 is pressed to release the snap fastener connection, so that the battery compartment end cover 10 automatically pops up under the action of the torsion spring, and at the same time the battery pops up under the action of the conical spring, so that the operator can take out the battery.
[0047] The above embodiment discloses a leveling instrument. When the instrument body 1 is placed on its side for use, the second plane arrow 7 is perpendicular to the ground. Then, the blocking member 5 is rotated to block the light-transmitting window 4. Then, the instrument body 1 is started. The laser head inside the instrument body 1 rotates and emits laser. Part of the laser is emitted through the blocking hole 6 on the blocking member 5, forming a lower point on the ground.
[0048] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
