Description

Technical Field

[0001] This utility model is a level gauge that can be adjusted at multiple angles, belonging to the field of level gauges. Background Technology

[0002] In industrial production, level gauges are key equipment for measuring liquid or material levels in containers. Their measurement accuracy and applicable scenarios directly affect production efficiency and quality. Traditional angle-adjustable level gauges typically consist of a fixed base, a rotating bracket, the level gauge body, and a simple adjustment mechanism. The rotating bracket is connected to the base via bearings or hinges to achieve angle adjustment of the level gauge. Some devices use manual bolt fastening or a snap-fit ​​structure to lock the angle.

[0003] However, existing angle-adjustable level gauges have obvious drawbacks. On the one hand, the angle adjustment range is limited, and most products can only achieve small angle adjustments in a single direction (such as horizontal or vertical), which cannot meet the multi-dimensional measurement needs under complex working conditions. On the other hand, the level gauges have poor installation compatibility. Their fixing structures mostly use customized clamps or single-specification slots, which are difficult to adapt to level gauge bodies of different sizes and models. When the equipment is updated or maintained, the installation components need to be redesigned, which increases the cost of use and time. Therefore, it is necessary to design a level gauge that can be adjusted at multiple angles. Utility Model Content

[0007] Furthermore, an opening is provided at the center of the bottom of the ball groove, and the inner diameter of the ball groove matches the outer diameter of the toothed ring, and the rotating ring is rotatably connected to the ball groove.

[0008] Furthermore, the inner diameter of the cover plate matches the outer diameter of the rotating ring, and the outer shape of the cover plate is consistent with the outer shape of the carrier. The top of the rotating ring extends out of the cover plate, and an annular angle scale line is provided at the edge of the top of the cover plate.

[0009] Furthermore, the mounting assembly includes a mounting frame, a second rotary handle, a bidirectional lead screw, a connecting plate, a hinge, a mounting plate, lead nuts, and V-shaped clamps. The mounting frame has grooves on both sides inside, and a bidirectional lead screw is installed within each groove. Both ends of the bidirectional lead screw are symmetrically fitted with matching lead nuts, and the shape of the lead nuts matches the shape inside the grooves. Mounting plates are symmetrically arranged at both ends inside the mounting frame, and both sides of the mounting plates are fixed to the lead nuts. V-shaped clamps are bolted to the opposite surfaces of the two mounting plates, and the level gauge body is clamped between the two V-shaped clamps. A second rotating handle is installed at the center of one end of the mounting frame, and the output end of the second rotating handle is connected to two bidirectional lead screws via a pulley mechanism. A hinge is integrally provided at the center of both sides of the mounting frame, and the hinge is rotatably connected to the hinge plate. The pulley mechanism includes two driven wheels connected to the bidirectional lead screws, a driving wheel connected to the output end of the second rotating handle, and a belt for driving the driving wheel and the driven wheel. A connecting plate is fixed to the top of the hinge near the arc-shaped adjustment frame by bolts, and the top of the connecting plate is connected to the movable sleeve by bolts.

[0010] Furthermore, the arc-shaped adjustment frame has an arch-shaped design, and a semi-circular arc-shaped through groove is provided on the arc-shaped adjustment frame.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a level gauge adjustable at multiple angles, including a carrier 1. A ball groove 101 is provided inside the carrier 1, and a rotating ring 7 is rotatably connected within the ball groove 101. A toothed ring 701 is provided on the outer side of the rotating ring 7, and hinge plates 4 are fixed to both sides of the top of the rotating ring 7. A drive chamber 103 is provided on one side inside the carrier 1, and a drive assembly 23 is provided within the drive chamber 103. An installation assembly 3 is hinged between the two hinge plates 4, and a level gauge body 5 is installed through the installation assembly 3. A cover is installed on the top of the carrier 1. Plate 2 and rotating ring 7 have two outwardly extending carrier plates 702 on one side of the top. An arc-shaped adjustment frame 6 is fixed on the top of the carrier plate 702. A movable sleeve 12 is movably connected to the arc-shaped adjustment frame 6. A limit component 13 is fixed on the top of the movable sleeve 12. One side of the top of the mounting component 3 is connected to the movable sleeve 12 through a connecting plate 17. The rotating ring 7 rotates in the ball groove 101 to adjust the horizontal angle. The movable sleeve 12 moves on the arc-shaped adjustment frame 6 to adjust the pitch angle. It can quickly adapt to the measurement needs under different working conditions and significantly improve the versatility of the application scenarios.

[0024] For example, the drive assembly 23 includes a worm gear 9, a secondary bevel gear 10, a primary bevel gear 11, and a first rotary handle 8. The worm gear 9 is disposed within the drive chamber 103 and meshes with the gear ring 701. The secondary bevel gear 10 is mounted on one end of the worm gear 9, and the primary bevel gear 11, meshing with the secondary bevel gear 10, is disposed within the drive chamber 103 on one side of the secondary bevel gear 10. The first rotary handle 8 is mounted on the cover plate 2 above the primary bevel gear 11, and the bottom output end of the first rotary handle 8 is connected to the middle of the primary bevel gear 11. The drive assembly 23 includes a worm gear 9, a secondary bevel gear 10, and a primary bevel gear 11. The first rotating handle 8 and the worm 9 are located in the drive chamber 103 and mesh with the gear ring 701. A secondary bevel gear 10 is installed at one end of the worm 9, and a main bevel gear 11 meshing with it is provided in the drive chamber 103 on one side of the secondary bevel gear 10. The first rotating handle 8 is installed on the cover plate 2 above the main bevel gear 11, and the bottom output end of the first rotating handle 8 is connected to the middle of the main bevel gear 11. The outer gear ring 701 of the rotating ring 7 meshes with the worm 9 in the drive assembly 23. Its transmission has a self-locking characteristic. After adjustment, no additional locking is required to avoid angular deviation due to vibration.

[0025] For example, an opening 102 is provided at the center of the bottom of the ball groove 101, and the inner diameter of the ball groove 101 matches the outer diameter of the toothed ring 701. The rotating ring 7 is rotatably connected to the ball groove 101. The inner diameter of the ball groove 101 matches the outer diameter of the toothed ring 701. This precise size matching allows the rotating ring 7 to be tightly embedded in the ball groove 101, ensuring the stability and smoothness of the rotation of the rotating ring 7. The opening 102 design facilitates the passage of the horn of the level gauge, making the design more reasonable.

[0026] Please see Figure 2 The inner diameter of the cover plate 2 matches the outer diameter of the rotating ring 7, and the outer shape of the cover plate 2 is consistent with the outer shape of the carrier 1. The top of the rotating ring 7 extends out of the cover plate 2, and an annular angle scale line is provided at the edge of the top of the cover plate 2. An indicator arrow can be provided on the top of the rotating ring 7 so that the operator can directly observe the rotation status of the rotating ring 7. Combined with the annular angle scale line on the top edge of the cover plate 2, the horizontal rotation angle of the level gauge can be read in real time and accurately without the need for additional measuring tools.

[0027] Please see Figure 4The mounting assembly 3 includes a mounting frame 14, a second rotary handle 15, a bidirectional lead screw 16, a connecting plate 17, a hinge 18, a mounting plate 19, a lead screw nut 20, and a V-shaped clamp 21. The mounting frame 14 has grooves 1401 on both sides inside, and the bidirectional lead screw 16 is installed in the grooves 1401. The two ends of the bidirectional lead screw 16 are symmetrically equipped with matching leads screw nuts 20, and the shape of the leads screw nuts 20 matches the internal shape of the grooves 1401. Mounting plates 19 are symmetrically arranged at both ends inside the mounting frame 14, and both sides of the mounting plates 19 are fixed to the leads screw nuts 20. V-shaped clamps 21 are bolted to the opposite surfaces of the two mounting plates 19, and the level gauge body 5 is clamped between the two V-shaped clamps 21. A second rotary handle 15 is installed at the center of one end of the mounting frame 14. The output end is connected to two bidirectional lead screws 16 via a pulley mechanism. A hinge part 18 is integrally provided at the center of both sides of the mounting frame 14, and the hinge part 18 is rotatably connected to the hinge plate 4. The pulley mechanism includes two driven wheels connected to the bidirectional lead screws 16, a driving wheel connected to the output end of the second rotating handle 15, and a belt for driving the driving wheel and the driven wheel. A connecting plate 17 is fixed to the top of the hinge part 18 near the arc-shaped adjustment frame 6 by bolts, and the top of the connecting plate 17 is connected to the movable sleeve 12 by bolts. When the second rotating handle 15 is rotated, the two screw nuts 20 move synchronously in opposite directions along the bidirectional lead screws 16, driving the mounting plate 19 and the V-shaped clamp 21 to symmetrically clamp the level gauge body 5. Compared with the clamping method of single-sided drive, symmetrical force can avoid the level gauge body 5 from tilting or eccentricity.

[0028] Please see Figure 3 The arc-shaped adjustment frame 6 has an arch-shaped design and a semi-circular arc-shaped through groove 601. The outer surface of the arc-shaped adjustment frame 6 has equal-spaced limit grooves 602. The shape of the movable sleeve 12 is adapted to the arc-shaped through groove 601. An angle scale line is provided on the outer side of the arc part of the arc-shaped adjustment frame 6. An observation port 1201 is provided at the center of the movable sleeve 12 near the scale line. The shape-adaptive design makes it difficult for the movable sleeve 12 to shake or loosen when it moves. The angle scale line and observation port 1201 design can ensure that the operator can intuitively obtain the adjustment angle, improving the efficiency and accuracy of the measurement orientation adjustment.

[0029] Please see Figure 5The limiting component 13 includes an adjusting screw 22, a mounting cylinder 24, and a limiting block 25. The mounting cylinder 24 is embedded in the top of the movable sleeve 12, and a mounting groove 2401 is provided inside the mounting cylinder 24. A limiting block 25 that matches the shape of the mounting groove 2401 is provided inside the mounting groove 2401, and a limiting ridge 2501 that engages with the limiting groove 602 is provided at the bottom of the limiting block 25. The top of the mounting cylinder 24 is threadedly connected to the adjusting screw 22, and the bottom of the adjusting screw 22 is rotatably connected to the top of the limiting block 25. When in use, rotating the adjusting screw 22 moves the limiting block 25 downward, and the limiting ridge 2501 engages with the corresponding position of the limiting groove 602 to complete the locking. The mounting groove 2401 and the limiting block 25 can be fitted with a rectangular cross section to ensure that the limiting block 25 can only move vertically and prevent lateral displacement that could cause jamming.

[0030] Detailed implementation: In use, rotating the first rotating handle 8 changes the rotation direction by 90° through the meshing of the main bevel gear 11 and the secondary bevel gear 10, and transmits this change to the worm gear 9. The worm gear 9 meshes with the toothed ring 701 on the outer side of the rotating ring 7, driving the rotating ring 7 to rotate within the ball groove 101. The top of the rotating ring 7 extends out of the cover plate 2, and the indicator arrow on its top, in conjunction with the annular angle scale line on the edge of the cover plate 2, allows for real-time reading of the horizontal rotation angle. Rotating the adjusting screw 22 moves the limiting block 25 upward, causing the limiting ridge 2501 to disengage from the limiting groove 602, thus releasing the lock. The movable sleeve 12 slides along the arc-shaped through groove 601 of the arc-shaped adjustment frame 6. The observation port 1201 is aligned with the outer angle scale line to determine the pitch angle. The adjusting screw 22 is rotated in the opposite direction, the limit block 25 moves down, and the limit ridge 2501 is engaged in the corresponding limit groove 602 to complete the locking. The second rotating handle 15 is rotated, and the two bidirectional lead screws 16 on both sides are driven to rotate synchronously through the belt pulley mechanism. The symmetrically distributed lead screw nuts 20 drive the mounting plate 19 and V-shaped clamping block 21 to move towards each other and clamp the level gauge body 5.
