Technical Field

[0001] This invention belongs to the field of leveling instrument technology, specifically a multifunctional leveling instrument for engineering surveying. Background Technology

[0002] A level is an instrument used to establish a horizontal line of sight and determine the height difference between two points on the ground. The principle is to measure the height difference between ground points based on the principle of leveling. The main components include a telescope, a tube level (or compensator), a vertical axis, a base, and leveling screws. According to the structure, it is divided into tilting level, automatic level, laser level, and digital level (also known as electronic level). According to the accuracy, it is divided into precision level and ordinary level.

[0003] Currently, existing levels are placed on a support frame during use. However, the support plane of this frame cannot be kept level with the ground when placed, so users need to adjust its levelness during use. This results in users spending a lot of time and effort to adjust the levelness of the support frame. In addition, existing levels are not convenient to quickly and securely install on the support frame for stable use. Furthermore, the support legs of existing level support frames cannot be quickly opened during use, nor can they be quickly folded up for carrying when not in use.

[0034] Please see Figure 1-6 The present invention provides a technical solution: a multifunctional level for engineering surveying, comprising a level body 1, a support frame 5 and a support device 8. The top of the level body 1 is fixedly connected to a handle 2, the bottom of the level body 1 is fixedly connected to a level mounting base 3, the bottom periphery of the level mounting base 3 is nested with the support frame 5, the top two sides of the support frame 5 are embedded with fixing devices 6, and the bottom of the support frame 5 is movably provided with the support device 8.

[0035] A circular groove 9 is embedded in the middle part of the inner side of the level instrument 1. A level instrument 10 is movably installed in the middle part of the level instrument 1. A micro liquid pump 12 is installed in the middle of the bottom of the level instrument 10.

[0036] The level instrument 10 is fixedly connected to both sides of the support rod 13. The support rod 13 is nested around the telescopic rod 14. The telescopic rod 14 is fixedly connected to both ends of the right side of the telescopic rod 14. The support rod 13 is provided with a contact spring assembly 16. The contact spring assembly 16 is fixedly connected to the right end of the arc-shaped slider 17.

[0037] The bottom of the fixing device 6 is fixedly provided with a convex limiting block 601, the middle of the fixing device 6 is fixedly connected with a triangular support column 603, the bottom of the middle of the triangular support column 603 is fixedly connected with a reinforcing mounting column 602, and the middle of the right side of the fixing device 6 is movably connected with an abutting threaded sleeve 19.

[0038] A threaded rod 20 is embedded and connected to the left side of the threaded sleeve 19, and a fixed post 23 is movably connected to the left end of the threaded rod 20;

[0039] A threaded sleeve 801 is nested in the middle periphery of the support device 8. A limiting ring 802 is fixedly connected to the bottom of the threaded sleeve 801. A connecting column 803 is fixedly installed at the bottom of the support device 8. A through shaft 804 is installed through the middle part of the connecting column 803. A movable support block 805 is movably installed at the bottom end of the connecting column 803.

[0040] Preferably, the outer bottom periphery of the fixing device 6 is nested with a limiting installation groove 4. The middle part of the limiting installation groove 4 is square, and the inner sides of both ends are embedded with installation grooves for limiting the convex limiting block 601. There are six limiting installation grooves 4, which are respectively set on the top of the support frame 5 and the top of the level instrument mounting base 3. The limiting installation grooves 4 can work with the fixing device 6 to better fix the entire level instrument 1 on the top of the support frame 5 for use.

[0041] Preferably, a carrying rope 7 is fixedly provided on the left side of the middle part of the support frame 5. When the user needs to carry the support frame 5 to other locations for use, the user can lift the support frame 5 by passing his palm through the carrying rope 7 and gripping the carrying rope 7. The carrying rope 7 makes it easier and more convenient for the user to move the support frame 5.

[0042] Preferably, a solid gravity block 11 is fixedly connected to the bottom of the level instrument 10. The solid gravity block 11 is inverted trapezoidal when viewed from the front. The inverted trapezoidal solid gravity block 11 can drive the level instrument 10 to maintain a parallel state with the ground through the self-adjusting leveling mechanism by gravity acting vertically downward. Thus, when the support frame 5 cannot provide support for the level instrument 10 to be parallel with the ground, the level instrument 10 will always maintain a parallel state with the ground under the action of the gravity of the solid gravity block 11.

[0043] Preferably, a ball bearing 18 is embedded on the right side of the arc-shaped slider 17. When the self-leveling mechanism is in operation, the self-leveling mechanism will rotate within the limiting ring bracket set on the periphery of the level instrument body 1 through the ball bearing 18 embedded on the outside of the arc-shaped slider 17 set at both ends of the bright support rod 13. The ball bearing 18 enables the self-leveling mechanism to quickly perform self-leveling and flipping under the influence of the gravity of the solid gravity block 11.

[0044] Preferably, two protruding posts 21 are fixedly provided at both ends of the left side of the threaded rod 20. When the user needs to rotate the threaded rod 20 to achieve the extension or retraction function, the user can manually rotate the protruding posts 21 to achieve the purpose of rotating the threaded rod 20. The setting of the protruding posts 21 makes it easier and more convenient for the user to rotate the threaded rod 20.

[0045] Preferably, a movable joint 22 is movably provided at the left end of the threaded rod 20. When the threaded rod 20 extends or retracts, the threaded rod 20 will drive the fixing device 6 to extend or retract simultaneously through the fixed post 23. In order not to affect the rotation of the threaded rod 20 in place, the movable joint 22 is used as the connecting part between the threaded rod 20 and the fixed post 23. Since the right side of the fixed post 23 is provided with a cavity for the movable joint 22 to rotate, the threaded rod 20 will not be restricted by the fixed post 23 when it drives the movable joint 22 to rotate.

[0046] Preferably, the level 10, together with the micro liquid pump 12, support rod 13, telescopic rod 14, connecting rod 15, contact spring assembly 16, and arc-shaped slider 17, forms a self-adjusting leveling mechanism. When the user needs to use the level 1 to measure the height of two different locations, the user first needs to unfold the support device 8 using the support extension mechanism, then erect the support frame 5 on the current measurement ground, and then fix the level 1 to the top of the support frame 5 using the fixing device 6. After the level 1 is fixed to the top of the support frame 5, when the support frame 5 is supported on the current ground, tilting occurs... When tilted, the level 10 in the middle of the level instrument assembly 1 will be horizontally rotated inside the level instrument assembly 1 due to the gravity of the solid weight block 11 at the bottom, via the ball bearings 18 on the outer side of the support rods 13 on both sides, so that the level 10 is parallel to the ground. Then, when the level 10 is in the current position and no longer rotates, the user can manually press the switch button located on the top right side of the level 10 to activate the micro liquid pump 12. When the micro liquid pump 12 is activated, it will draw the driving fluid inside the telescopic rods 14 on the outer side of the support rods 13 on both sides of the level 10 back into the inner cavity, so that the telescopic rods 14... 4. When the telescopic rod 14 retracts, it drives the arc-shaped slider 17 to retract inwards via the connecting rod 15. (When the arc-shaped slider 17 retracts, the contact spring assembly 16 will retract due to force, and when the force is no longer applied, it will push the arc-shaped slider 17 to move outwards, allowing the ball bearing 18 to fit more tightly against the inner wall of the circular groove embedded in the inner side of the level instrument assembly 1). This causes the ball bearing 18 located outside the arc-shaped slider 17 to no longer fit against the inner outer wall of the circular groove embedded in the inner side of the level instrument assembly 1. When the telescopic rod 14 retracts inwards, it will be subjected to the circular groove that provides the rolling force for the ball bearing 18. The level 10 is kept in its current position by the restriction inside the groove, so that it is stably limited to the current position for use. With this setting, when the user supports the support frame 5 at the current measurement location through the support device 8, the level 10 as a whole can be brought into a parallel state with the current ground by the self-adjusting leveling mechanism set on the inside when the support surface provided by the support frame 5 is not parallel to the current ground. Then, the level 10 is limited and fixed in a parallel state with the ground. Thus, the user no longer needs to adjust the level 10 itself through cumbersome steps when using the level 10.

[0047] Preferably, the convex limiting block 601, together with the reinforcing mounting post 602, the triangular support post 603, the abutting threaded sleeve 19, the threaded rod 20, and the fixing post 23, forms a fixed positioning mechanism. When the user supports the support frame 5 at the current measurement location using the support tensioning mechanism, the user can manually insert the level mounting base 3 at the bottom of the level instrument assembly 1 into the pre-installed slot at the top of the support frame 5, and then manually rotate the convex post 21 clockwise to drive the threaded rod 20 to rotate clockwise. By rotating, the threaded rod 20 will slowly engage with the inner side of the threaded sleeve 19 through the threads on its right outer periphery. When the threaded rod 20 engages with the inner side of the threaded sleeve 19, the threaded rod 20 can bring the fixing devices 6 closer together through the fixing post 23, thus reducing the width of the fixing devices 6. Then, the user can insert the close-fitting convex limiting block 601 into the middle part of the limiting mounting groove 4. Afterward, the user can manually rotate the protruding post 21 counterclockwise to slowly disengage the threaded rod 20 through the threads on the inner side of the threaded sleeve 19. When the threaded rod 20 disengages from the inner side of the threaded sleeve 19, the width of the fixing device 6 is expanded. As the width of the fixing device 6 increases, the convex limiting block 601 at the bottom of the fixing device 6 inserts into both ends of the inner side of the limiting mounting groove 4. Because the two ends of the limiting mounting groove 4 are provided with slots for limiting the convex limiting block 601, the fixing device 6 is firmly fixed in its current position. Furthermore, because the fixing device 6 is provided with a triangular support post 603, the fixing device 6 is even more robust. After the fixing device 6 is firmly abutted and limited at the top of the level instrument mounting base 3 and the support frame 5, the entire level instrument 1 will be firmly fixed on the support frame 5 and put into use. With this setting, after the user places the support frame 5 on the current measurement location using the support tensioning mechanism, the user can quickly and conveniently fix the entire level instrument 1 on the top of the support frame 5 and put it into use by using the fixing device 6 in the fixing positioning mechanism. Thus, the entire level instrument 1 can be quickly fixed on the top of the support frame 5 and put into use.

[0048] Preferably, the support device 8, together with the threaded sleeve 801, the limiting ring 802, the connecting column 803, the through shaft 804, and the movable support block 805, forms a support tensioning mechanism. Three movable support blocks 805 are provided, and each movable support block 805 is movably connected to the support device 8 via the through shaft 804. The diameter of the threaded sleeve 801 is larger than the diameter of the circle formed by the three movable support blocks 805 when they are closed. When the user needs to carry the support frame 5 to other locations, the user can manually tension the bottom of the movable support block 805 at the bottom of the support device 8. The three movable support blocks 805 are pushed together, causing them to rotate around the through shaft 804, forming a single cylinder. The user can then manually rotate the threaded sleeve 801 clockwise, causing it to slowly move downwards along its inner threads. As the threaded sleeve 801 moves downwards, it also moves the limiting ring 802 downwards. Once the threaded sleeve 801 has completely enveloped the connecting post 803 and the through shaft 804, the movable support blocks 805 will be unable to rotate due to the restriction imposed by the threaded sleeve 801, allowing the user to... This allows for easier movement of the support frame 5. Conversely, when the user needs to use the support frame 5 to support the entire level instrument 1, the user can manually rotate the threaded sleeve 801 counterclockwise, causing the threaded sleeve 801 to slowly move upwards. Once the threaded sleeve 801 has moved to the position where it is disengaged from the connecting column 803 and the through shaft 804, the user can manually push the bottom of the three movable support blocks 805 outwards, causing the movable support blocks 805 to open. After the movable support blocks 805 are opened to a certain angle, they will be restricted by the limiting ring 802. The movable support block 805 is kept in an open state to support the support frame 5, allowing the support frame 5 to stand stably at the current location and be put into use. This design allows the user to more easily change the state of the movable support block 805 by using the support retraction mechanism located on the support device 8 at the bottom of the support frame 5. When the user needs to move the support frame 5, the user can better limit and store the movable support block 805 by using the support retraction mechanism, making it more convenient for the user to carry the support frame 5.

[0049] Working principle: First, when the user needs to use the level instrument 1 to measure the height of two different locations, the user needs to first unfold the support device 8 using the support extension mechanism, and then limit the unfolded support device 8 to allow the support frame 5 to stand stably in the current position through the three movable support blocks 805 after being extended. After the support frame 5 is stably standing in the current position, the user can place the level instrument 1 on top of the support frame 5, and then use the fixing device 6 to fix and restrict the level instrument 1 to the top of the support frame 5. After the level instrument 1 is fixedly installed, the level instrument 1 can drive the level instrument 10 to be parallel to the current ground through the self-adjusting leveling mechanism set on the inside, so that the user no longer needs to adjust the level of the level instrument 10 when using it. This is the working principle of this multi-functional level instrument for engineering surveying.
