Description

Technical Field

[0001] This utility model relates to the technical field of level bases, specifically a leveling base for a level. Background Technology

[0002] A laser level is a comprehensive instrument integrating optics, mechanics, electronics, and computers. The instrument consists of two parts: a main unit and a projector. The main unit collects the attitude signal or manual signal from the level and processes the signal to control the optical scanning system to scan in real time. The projector uses a laser system (including a semiconductor laser, laser power supply, and optical system) and an optical scanning system to generate a laser scanning line under the control of the main unit. This line is projected onto the horizon in any direction and position in two-dimensional space.

[0003] Chinese Patent Publication No. CN209013998U discloses a laser level, including a base. A knob is located on the outer side of the base, and a support leg is rotatably connected to the outer side of the base via the knob. An adjustment knob is located on the support leg. An adjustment box is located on the top of the base, and a fine-tuning handwheel is located on one side of the adjustment box. A turntable is located on the top of the adjustment box, and a first connecting shaft is located at the top of one side of the turntable. This invention features a first connecting shaft at the top of one side of the turntable, with the top of the turntable rotatably connected to the instrument body via the first connecting shaft.

The base includes a lower plate with supporting feet at its bottom. A coaxial geared disc, a first pressure plate, a second pressure plate, and an upper plate are sequentially mounted on the lower plate. A knob is connected to the side of the lower plate, extending into the lower plate and connected to a gear that meshes with the geared disc. The second pressure plate is locked to the lower plate with screws to prevent longitudinal movement of the geared disc and the first pressure plate, but a gap is maintained between the second pressure plate and the geared disc, meaning the second pressure plate is in contact with the base, thus not affecting the flexible rotation of the geared disc. The upper plate is fixed to the first pressure plate with screws to prevent longitudinal movement of the upper plate.

[0005] However, the inventor of the above-mentioned device believes that it has certain defects. The above-mentioned device uses the method of manually adjusting the extension and retraction of the support legs and visually observing the level to level the base, which is cumbersome and has a large error. Therefore, this utility model provides a leveling base for a level. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A leveling base for a level includes an upper cover 1 and a base 6. A control circuit board 3 is embedded inside the base 6. A power connector 2 is embedded on the upper cover 1. The power connector 2 is electrically connected to the control circuit board 3. The control circuit board 3 has two copper plates with positive and negative poles for contacting the circuit board and energizing it. A fixed gear seat 4 is rotatably connected inside the base 6. The upper cover 1 is rotatably connected to the top of the fixed gear seat 4. The fixed gear seat 4 is hollow. One end of the upper cover 1 is rotatably connected to the top of the fixed gear seat 4.

[0024] Please refer to it again. Figure 2 and Figure 3 The upper cover 1 is equipped with an electric component for driving the upper cover 1 to rotate. The electric component includes a first motor 41 embedded in the inner top wall of the upper cover 1. The output shaft end of the first motor 41 is fixedly connected to a rotating gear 42. The rotating gear 42 meshes with a fixed gear seat 4. By starting the first motor 41, the rotating gear 42 is driven to rotate. Under the meshing action of the rotating gear 42 and the fixed gear seat 4, the upper cover 1 is driven to rotate around the top of the fixed gear seat 4. The model of the first motor 41 is 24BYJ48.

[0025] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A manual worm gear 5 is fixedly connected to the bottom of the fixed gear seat 4. A mounting column is fixedly connected inside the chassis 6. The manual worm gear 5 is rotatably connected to the mounting column. A worm 61 is rotatably connected to the inner wall of the chassis 6. The worm 61 meshes with the manual worm gear 5. By rotating the knobs at both ends of the worm 61, the manual worm gear 5 is driven to rotate inside the chassis 6 due to the meshing action of the worm 61 and the manual worm gear 5. This causes the fixed gear seat 4 and the top cover 1 to rotate together. The worm 61 and the manual worm gear 5 form a self-locking mechanism, so that the fixed gear seat 4 remains fixed and does not rotate when the rotating gear 42 rotates.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 Three motor covers 7 are fixedly connected to the bottom of the chassis 6. Telescopic support legs 8 are slidably connected to the bottom of the motor covers 7. Connecting slide bars 81 are fixedly connected to the top of the telescopic support legs 8. The connecting slide bars 81 are rectangular strips and are slidably connected to the bottom of the motor covers 7. The sliding groove at the bottom of the motor covers 7 is rectangular. The horizontal tilt angle of the chassis 6 can be adjusted by driving the connecting slide bars 81 to slide and extend at the bottom of the motor covers 7.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4The motor housing 7 houses a drive assembly that drives the telescopic support legs 8 to slide at the bottom of the motor housing 7. A level sensor is embedded in the control circuit board 3. The drive assembly includes a second motor 71 fixed inside the motor housing 7. An adjusting screw 72 is fixedly connected to the output shaft of the second motor 71. The adjusting screw 72 is threaded into the interior of the connecting slide bar 81. The level sensor is an electronic sensing device used to detect changes in the tilt angle or orientation of an object relative to the horizontal plane and converts the physical signal into a measurable electrical signal output. Its core function is to monitor the tilt state of the environment or equipment. Both the second motor 71 and the level sensor are electrically connected to the control circuit board 3. The level sensor transmits electrical signals to the control circuit board 3, which then controls the second motor 71 to start, driving the adjusting screw 72 to rotate, causing the connecting slide bar 81 to extend and retract outwards, thereby automatically leveling the device.

[0028] Working principle: The level is installed on the top of the cover 1 and the power connector 2 of the device is connected to the power supply of the level to power it. The level sensor is set to detect the tilt angle or orientation change relative to the horizontal plane. The level sensor transmits the electrical signal to the control circuit board 3. The control circuit board 3 controls the second motor 71 to start, so that the adjusting screw 72 rotates. Under the action of the connecting slide bar 81, the telescopic support 8 slides and extends at the bottom of the motor cover 7 to automatically level the whole device. By starting the first motor 41, the rotating gear 42 is driven to rotate, so that the whole cover 1 rotates around the top of the fixed gear seat 4 to adjust the rotation of the vertical light of the level installed on the cover 1.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
