Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment for engineering supervision, specifically a collapsing bucket level adjustment mechanism. Background Technology

[0002] To ensure the smooth progress of construction, a slump bucket is typically used to test the slump of concrete. In operation, the slump bucket is placed on a horizontal surface, and the concrete mixture is filled according to a prescribed method. After filling and leveling, the bucket is lifted vertically upwards and moved aside. The concrete mixture will slump due to its own weight. The dimension of the slump is then measured; this dimension is the slump, an indicator of fluidity. A higher slump indicates better fluidity. To ensure the accuracy of the test, a leveling mechanism is usually used to adjust the slump bucket.

[0003] The existing leveling mechanism generally consists of a bracket and a threaded rod. In use, by observing the level measuring instrument on the surface and rotating the bolts at the corresponding positions, the bracket can be shifted up and down, thereby making the surface of the bracket tend to be level.

[0004] However, in actual use, if the bracket is tilted at a large angle, since the bolts are directly installed on the bracket, the angle between the threaded rod and the support plate will gradually deviate from the vertical direction during adjustment. As a result, when the bracket is not kept at a level surface, it will directly jam with the threaded rod, making adjustment impossible and reducing the flexibility of use. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slump bucket level adjustment mechanism, including a bracket, with connecting pieces hinged at each of the four corners of the bracket, a support leg fixedly connected to the bottom end of the connecting piece, a threaded rod threadedly connected inside the support leg, a limit block slidably connected inside the connecting piece, and two rubber sheets sleeved on the outside of the threaded rod, with the inner side of the rubber sheets fitting against the bracket.

[0007] Preferably, the threaded rod has an internal mounting groove, a pull rope is slidably connected inside the mounting groove, an elastic element is sleeved on the outside of the pull rope, a compression block is fixedly connected to one end of the pull rope, a pull ring is fixedly connected to the other end of the pull rope, a push rod is fixedly connected to the end of the compression block away from the elastic element, the other end of the push rod is fixedly connected to a limiting block, and two limiting grooves are formed on the outer side of the threaded rod.

[0008] Preferably, the connecting piece has multiple slots on both the upper and lower sides, multiple inserts are fixedly connected to the inner side of the rubber sheet, a conical block is fixedly connected to the outer side of the insert, and an arc-shaped block is fixedly connected to the side of the insert away from the rubber sheet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a collapsible bucket level adjustment mechanism, including a support 1, with connecting pieces 2 hinged at each of the four corners of the support 1, allowing the connecting pieces 2 to shift. A support leg 3 is fixedly connected to the bottom end of the connecting piece 2, and a threaded rod 4 is threadedly connected inside the support leg 3. The threaded rod 4 is rotatably connected inside the connecting piece 2, and the connecting piece 2 limits the threaded rod 4, allowing the threaded rod 4 to drive the connecting piece 2 to move upward. A limit block 10 is slidably connected inside the connecting piece 2, and the limit block 10 fits against the connecting piece 2, thereby limiting the threaded rod 4. Two rubber sheets 13 are sleeved on the outside of the threaded rod 4, and the inner side of the rubber sheets 13 fits against the support 1, resulting in greater friction at the connection between the connecting piece 2 and the support 1, thus limiting the connecting piece 2.

[0024] When the bracket 1 needs to be adjusted, the threaded rod 4 is rotated, causing the connecting piece 2 to move upward. This allows the connecting piece 2 to rotate on the bracket 1, which in turn causes the rubber sheet 13 to rub against the bracket 1. Once the threaded rod 4 stops rotating, the positions of the bracket 1 and the connecting piece 2 are restricted, and the limiting block 10 slides inside the connecting piece 2. This increases the friction between the threaded rod 4 and the connecting piece 2, preventing the threaded rod 4 from rotating when not in use. This results in higher stability of the bracket 1 after adjustment, making it more flexible to use and allowing for more convenient positioning of the bracket 1.

[0025] Example 2: Based on Example 1, to facilitate the rotation of the threaded rod 4, an installation groove 5 is provided inside the threaded rod 4. A pull rope 6 is slidably connected inside the installation groove 5, and the installation groove 5 limits the movement of the pull rope 6, allowing it to slide smoothly. An elastic element 7 is sleeved on the outside of the pull rope 6. One end of the pull rope 6 is fixedly connected to a pressing block 8. One end of the elastic element 7 is fixedly connected to the inner wall of the installation groove 5, and the other end is fixedly connected to the pressing block 8. The pressing block 8 is slidably connected inside the installation groove 5, and the installation groove 5 limits the movement of the pressing block 8, preventing it from collapsing during movement. The other end of the pull rope 6 is fixedly connected to a pull ring 12. The inner side of the pull ring 12 fits against the outer side of the threaded rod 4, making the pull ring 12 more stable. The end of the compression block 8 away from the elastic element 7 is fixedly connected to a push rod 9. The push rod 9 is slidably connected inside the mounting groove 5. The mounting groove 5 limits the push rod 9, allowing the push rod 9 to move smoothly. The other end of the push rod 9 is fixedly connected to the limiting block 10. Two limiting grooves 11 are opened on the outer side of the threaded rod 4. The limiting block 10 is slidably connected inside the limiting grooves 11. The limiting grooves 11 limit the limiting block 10, allowing the limiting block 10 to move smoothly.

[0026] When the threaded rod 4 needs to be rotated, the two pull rings 12 are pulled to opposite sides, causing the pull rings 12 to pull the pull rope 6 upward. This causes the pull rope 6 to pull the compression block 8 to compress the elastic element 7, causing deformation. The compression block 8 then pulls the push rod 9 inward, causing the push rod 9 to drive the limiting block 10 to slide inward within the limiting groove 11. This separates the limiting block 10 from the connecting piece 2, allowing the threaded rod 4 to rotate. Conversely, by releasing the pull rings 12, the elastic element 7 returns to its original position, pushing the compression block 8 outward. This causes the compression block 8 to push the limiting block 10 outward via the push rod 9, allowing the limiting block 10 to fit against the inner wall of the connecting piece 2. This results in greater friction between the connecting piece 2 and the threaded rod 4, preventing the threaded rod 4 from rotating when not in use and ensuring higher installation stability of the bracket 1.

[0027] Example 3: Based on Example 2, in order to facilitate the replacement of the rubber sheet 13 and achieve high installation stability, multiple slots 17 are provided on both the upper and lower sides of the connecting piece 2. Multiple inserts 14 are fixedly connected to the inner side of the rubber sheet 13. The inserts 14 are inserted into the inside of the slots 17, so that the rubber sheet 13 can be installed on the connecting piece 2. A conical block 15 is fixedly connected to the outside of the inserts 14. The outer slope of the conical block 15 is relatively stable compared to the inner arc surface, so that the conical block 15 can easily slide into the inside of the slot 17, so that the slot 17 can squeeze the conical block 15 to produce deformation, and the conical block 15 fits into the slot 17. An arc-shaped block 16 is fixedly connected to the side of the insert 14 away from the rubber sheet 13. The arc-shaped block 16 is slidably connected to the inside of the slot 17. The arc surface of the arc-shaped block 16 can slide outside the connecting piece 2, so that the arc-shaped block 16 can easily enter the inside of the slot 17.

[0028] When the rubber sheet 13 needs to be installed, the insert block 14 is inserted into the slot 17. At this time, the arc block 16 and the conical block 15 slide into the slot 17, and the conical block 15 is squeezed and deformed, which allows the conical block 15 to perform a reset movement. This makes the insertion of the insert block 14 into the slot 17 more stable, and thus makes the connection between the rubber sheet 13 and the connecting piece 2 more stable. Conversely, by pulling the rubber sheet 13 outward, the outer slope of the conical block 15 can slide inside the connecting piece 2, which makes the rubber sheet 13 easy to disassemble.

[0029] In actual use, by inserting the insert 14 into the slot 17, both the arc-shaped block 16 and the conical block 15 slide into the slot 17, causing the conical block 15 to be compressed and deformed, thus allowing it to return to its original position. This makes the insertion of the insert 14 into the slot 17 more stable, and the connection between the rubber sheet 13 and the connecting piece 2 more stable. Then, by pulling the two pull rings 12 to opposite sides, the pull rings 12 pull the pull rope 6 upwards, causing the pull rope 6 to pull the compression block 8 to compress the elastic element 7, causing it to deform. This causes the compression block 8 to pull the push rod 9 inwards, causing the push rod 9 to drive the limiting block 10 to slide inwards within the limiting groove 11, thus separating the limiting block 10 from the connecting piece 2. This causes the threaded rod 4 to rotate, causing the threaded rod 4 to drive the connecting piece 2 upwards, thus allowing the connecting piece 2 to move onto the bracket 1. The rotation causes the rubber sheet 13 to rub against the bracket 1, preventing the threaded rod 4 from rotating. This restricts the position of the bracket 1 and the connecting piece 2, and the limiting block 10 slides inside the connecting piece 2. This increases the friction between the threaded rod 4 and the connecting piece 2, preventing the threaded rod 4 from rotating when not in use. Then, by releasing the pull ring 12, the elastic element 7 returns to its original position, pushing the compression block 8 outward. This pushes the limiting block 10 outward via the push rod 9, causing the limiting block 10 to fit against the inner wall of the connecting piece 2. This increases the friction between the connecting piece 2 and the threaded rod 4, preventing the threaded rod 4 from rotating when not in use. This results in higher stability of the bracket 1 after adjustment, increasing its flexibility and allowing for better positioning of the bracket 1, making it more convenient to use.
