Description

Technical Field

[0001] This utility model relates to the field of leveling instrument technology, specifically to a component for leveling instrument testing that facilitates direction adjustment. Background Technology

[0002] A level is a precision instrument used to establish a horizontal line of sight and measure the elevation difference between two points on the ground. Its core function is to determine the elevation difference through the principle of leveling. It is widely used in fields such as construction engineering, topographic surveying, and equipment installation. It establishes a horizontal line of sight using components such as a telescope and a level, and calculates the elevation difference using the leveling rod reading. In practical use, the level requires rotating the telescope to adjust its orientation so that the observation range is aligned with the leveling rod reading. However, existing level instruments do not have a coarse adjustment mechanism for the telescope rotation, and the built-in orientation adjustment range of the telescope is extremely small. Therefore, manual rotation of the telescope is often necessary to adjust it to the range of the built-in orientation. In practice, manual rotation of the telescope often results in over-rotation or under-rotation due to hand tremors, requiring multiple adjustments based on the feel of the instrument. This is a common problem encountered by construction workers in actual surveying and measurement, making the operation of the level instrument inconvenient. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a component for convenient direction adjustment in level instrument testing, thus solving the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a component for convenient direction adjustment of a level instrument, comprising a level instrument body and a leveling handwheel seat, a base plate disposed between the level instrument body and the leveling handwheel seat, the bottom of the base plate being installed and connected to the lifting rod of the leveling handwheel seat, a sleeve fixedly disposed on the top of the base plate, a core cylinder, an eccentric cylinder, and a shaft bolt being sleeved inside the core cylinder, the top surface of the core cylinder being fixedly connected to the bottom surface of the level instrument body, the bottom surface of the core cylinder being rotatably connected to the top surface of the base plate, and a resistance rotating part fixedly sleeved on the surface of the core cylinder. The eccentric cylinder has a driven gear ring disc and a driven gear ring disc. The bottom surface of the eccentric cylinder is rotatably connected to the top surface of the base plate. The surface of the eccentric cylinder is fixedly fitted with a driving gear ring disc and a toggle adjustment disc. The surface of the driving gear ring disc is fitted with a closed transmission belt. The teeth of the outer ring of the driving gear ring disc are connected to the teeth of the outer ring of the driven gear ring disc through the closed transmission belt. The bottom surface of the shaft bolt is rotatably connected to the top surface of the base plate. The surface of the shaft bolt is fixedly fitted with a rotating sleeve. The annular outer surface of the rotating sleeve is fixedly connected with an arc-pressed bonding plate. The right end of the arc-pressed bonding plate extends to the outside of the sleeve cylinder.

[0005] Preferably, a plurality of compression springs are fixedly provided on the back of the arc-pressed bonding plate, and the plurality of compression springs are distributed at equal distances on the surface of the arc-pressed bonding plate, and the other end of the compression springs is fixedly connected to the inner wall of the sleeve.

[0006] Preferably, a threaded push rod is inserted into the right side of the casing cylinder, and the surface of the threaded push rod is threadedly connected to the inner wall of the casing cylinder. A trapezoidal push block is rotatably connected to the left side of the threaded push rod. The top surface of the trapezoidal push block slides in contact with the base plate of the level instrument body, and the bottom surface of the trapezoidal push block slides in contact with the top surface of the base plate. A movable inclined block is fixedly provided on the front side of the arc-fitting plate, and the right inclined surface of the movable inclined block slides in contact with the left inclined surface of the trapezoidal push block.

[0008] Preferably, the drive gear ring is located directly above the actuation adjustment disc, and the surface of the actuation adjustment disc is fixedly fitted with an anti-slip outer sleeve.

[0009] This invention provides a component for convenient direction adjustment in a leveling instrument. It offers the following advantages: (1) The level instrument uses a component that is easy to adjust the direction. By rotating the adjustment disc, the driving gear ring disc is driven to rotate inside the sleeve. The driving gear ring disc is connected to the driven gear ring disc by a closed transmission belt, which drives the shaft cylinder to rotate. This allows the level instrument to be slowly and stably adjusted by rotating the right side of the anti-slip outer sleeve as needed. After adjustment, the compression spring applies pressure to the pressure arc bonding plate, which forms resistance on the outer protective sleeve of the resistance turntable. This allows the shaft cylinder to be positioned at any time after the angle is adjusted. This avoids the need for the surveyor to make multiple fine adjustments by hand and also avoids the phenomenon of accidental touch on the level instrument body during continuous operation, which can easily cause the direction to deviate.

[0012] 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.

[0013] like Figure 1-4As shown, this utility model provides a technical solution: a component for convenient direction adjustment in a leveling instrument, including a leveling instrument body 1 and a leveling handwheel seat 4. A base plate 3 is provided between the leveling instrument body 1 and the leveling handwheel seat 4. The bottom of the base plate 3 is installed and connected to the lifting rod of the leveling handwheel seat 4. A sleeve cylinder 2 is fixedly installed on the top of the base plate 3. A shaft cylinder 5, an eccentric cylinder 9, and a shaft bolt 14 are sleeved inside the sleeve cylinder 2. The top surface of the shaft cylinder 5 is fixedly connected to the bottom surface of the leveling instrument body 1, and the bottom surface of the shaft cylinder 5 is rotatably connected to the top surface of the base plate 3. A resistance turntable 6 and a driven gear ring 7 are fixedly sleeved on the surface of the shaft cylinder 5. The driven gear ring 7 is located directly above the resistance turntable 6. A resistance outer protective sleeve 8 is fixedly sleeved on the surface of the resistance turntable 6. The protective sleeve 8 of the resistance jacket increases the rotational resistance of the resistance turntable 6 by pressing the arc-fitting plate 16. The bottom surface of the eccentric cylinder 9 is rotatably connected to the top surface of the base plate 3. The surface of the eccentric cylinder 9 is fixedly fitted with a drive gear ring 11 and a turning adjustment plate 10. The drive gear ring 11 is located directly above the turning adjustment plate 10. The surface of the turning adjustment plate 10 is fixedly fitted with an anti-slip sleeve 13. The anti-slip sleeve 13 facilitates the measurement personnel to turn the turning adjustment plate 10 stably. The surface of the drive gear ring 11 is fitted with a closed transmission belt 12. The teeth of the outer ring of the drive gear ring 11 are connected to the driven gear ring through the closed transmission belt 12. The gear transmission connection of the outer ring of the disc 7, the bottom surface of the shaft bolt 14 and the top surface of the base plate 3 are rotatably connected. Through the arrangement of the shaft cylinder 5, driven gear ring disc 7, eccentric cylinder 9, adjusting disc 10 and driving gear ring disc 11, the adjusting disc 10 is rotated, which drives the driving gear ring disc 11 to rotate inside its sleeve cylinder 2. The driving gear ring disc 11 is connected to the driven gear ring disc 7 via a closed transmission belt 12, which drives the shaft cylinder 5 to rotate, so as to achieve precise and stable adjustment of the telescope position of the level instrument body 1 to the accurate range. The surface of the shaft bolt 14 is fixedly fitted with a rotating sleeve 15. The annular outer surface of the rotating sleeve 15 is fixedly connected with an arc-pressed bonding plate 16. The right end of the arc-pressed bonding plate 16 extends To the outside of the sleeve cylinder 2, multiple compression springs 17 are fixedly installed on the back of the arc-pressing bonding plate 16. The multiple compression springs 17 are evenly distributed on the surface of the arc-pressing bonding plate 16, and the other end of the compression springs 17 is fixedly connected to the inner wall of the sleeve cylinder 2. The arrangement of multiple compression springs 17 provides a stable pushing force to the arc-pressing bonding plate 16, so that the arc-pressing bonding plate 16 provides a stable squeezing force to the resistance outer protective sleeve 8 when no force is applied, and provides a resistance positioning effect in the rotation direction of the resistance turntable 6. A threaded push rod 18 is inserted into the right side of the sleeve cylinder 2. The surface of the threaded push rod 18 is threadedly connected to the inner wall of the sleeve cylinder 2. A trapezoidal push block 19 is rotatably connected to the left side of the threaded push rod 18.The top surface of the trapezoidal push block 19 slides in contact with the base plate of the level instrument body 1, and the bottom surface of the trapezoidal push block 19 slides in contact with the top surface of the base plate 3. A movable inclined block 20 is fixedly installed on the front side of the arc-fitting plate 16. The right inclined surface of the movable inclined block 20 slides in contact with the left inclined surface of the trapezoidal push block 19. Through the arrangement of the threaded push rod 18, the trapezoidal push block 19, and the movable inclined block 20, the threaded push rod 18 drives the trapezoidal push block 19 to move inward, thus... By utilizing the difference in slope displacement between the trapezoidal pusher 19 and the inclined plane block 20, the pressure arc bonding plate 16 is driven to swing counterclockwise, contacting and separating from the resistance outer protective sleeve 8 set on the outside of the resistance turntable 6. This controls the rotation of the resistance turntable 6. In conjunction with the force exerted on the pressure arc bonding plate 16 by multiple compression springs 17, the rotation of the resistance turntable 6 can be controlled at any time, preventing accidental contact with the level instrument body 1 during continuous operation and thus avoiding directional deviation.

[0014] In use, when it is necessary to rotate and adjust the position of the telescope of the level body 1, rotate the threaded push rod 18 to drive the trapezoidal push block 19 to move inward. Utilizing the difference in displacement between the trapezoidal push block 19 and the inclined plane block 20, the pressure arc bonding plate 16 swings counterclockwise, contacting and separating from the resistance outer protective sleeve 8 on the outside of the resistance turntable 6, allowing the resistance turntable 6 to rotate without resistance. Then, adjust the telescope to the appropriate position manually and slowly rotate the anti-slip outer sleeve 13 clockwise or counterclockwise to drive the adjustment disc 10 to rotate. The adjustment disc 10 then drives the drive gear ring disc 11 to rotate inside its casing 2. Through the closed transmission mechanism of the drive gear ring disc 11… The drive belt 12 is connected to the driven gear ring 7, which drives the shaft cylinder 5 to rotate. After the telescope of the level body 1 is accurately and stably adjusted to the precise range, the threaded push rod 18 is rotated in the opposite direction, causing the trapezoidal push block 19 to move outward. At this time, multiple compression springs 17 provide a supporting force to the arc-shaped bonding plate 16, so that the arc-shaped inner wall of the arc-shaped bonding plate 16 and the resistance outer protective sleeve 8 sleeved on the outside of the resistance turntable 6 form a strong resistance, which constrains and positions the rotation of the shaft cylinder 5. Then, the calipers at a distance can be adjusted and the level body 1 can be used to start measuring and reading. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0015] In summary, this level instrument utilizes a conveniently adjustable component. By rotating the adjustment disc 10, the driving gear ring disc 11 rotates inside the housing 2. The driving gear ring disc 11, connected to the driven gear ring disc 7 via a closed transmission belt 12, drives the shaft cylinder 5 to rotate. This allows for slow and stable adjustment of the level instrument body 1's rotation direction by rotating the right side of the anti-slip outer sleeve 13 as needed. After adjustment, the compression spring 17 applies pressure to the pressure arc bonding plate 16, causing the resistance outer sleeve 8 on the outside of the resistance turntable 6 to form resistance. This allows for easy positioning of the adjusted shaft cylinder 5, avoiding the need for multiple fine adjustments by the surveyor and preventing accidental misalignment of the level instrument body 1 during continuous operation.
