Detailed Implementation

[0017] The present invention will now be described in detail and completely with reference to the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention with reference to the accompanying drawings, it should be particularly noted that the technical solutions and features provided in various parts of the present invention, including the following description, can be combined with each other without conflict.

[0018] Furthermore, the embodiments of the present invention described below are generally only some, not all, of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0019] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific implementation process is as follows: Reference Figures 1-8 This is the first embodiment of the present invention, which proposes... A leveling device for cast-in-place concrete base surfaces, comprising: 100 racks; Mounting base 200 is slidably mounted on frame 100; Two sliding brackets 300 are slidably mounted on the mounting base 200. The two sliding brackets 300 slide closer to each other or further apart. There are several scrapers 500, which are respectively set on two sliding frames 300. When the two sliding frames 300 slide, they drive the scrapers 500 to slide. The scrapers 500 are raised and lowered on the sliding frames 300.

[0021] In this embodiment, to address the issue of traditional large-scale leveling equipment such as laser levelers being difficult to deploy or access in areas with small floor space and limited room availability due to their bulky size and poor operational flexibility, thus requiring manual leveling, this solution designs an automatic leveling device. By sliding two frames 300, the area leveled by the sliding plate is changed. This solution can be designed with two rows of scrapers 500 on the sliding frames 300, with each row staggered. When the mounting base 200 drives the sliding frames 300 to slide on the frame 100, both rows of scrapers 500 simultaneously level the concrete, achieving a better effect than leveling only once. Furthermore, since the sliding frames 300 are suspended on the frame 100, it reduces the need for equipment or workers to step on the concrete, further facilitating leveling. The scraper 500 can be raised and lowered to adjust the thickness of the leveled concrete according to different situations, broadening its applicability.

[0022] Furthermore, the sliding frame 300 has a horizontal sliding rod 310 and a vertical support rod 320. The horizontal sliding rod 310 is slidably mounted on the mounting base 200. After the horizontal sliding rod 310 slides, it drives the vertical support rod 320 to move closer or further apart. It also includes: The fastener 400 has two parts, one end of which is set on the mounting base 200, and the other end is slidably set on the vertical support rod 320.

[0023] In this embodiment, in order to prevent the sliding frame 300 from sliding too far and sinking, which would prevent the scraper 500 from leveling the concrete, a fixing member 400 is designed. After the sliding frame 300 slides to the corresponding position, the fixing member 400 fixes the sliding frame 300 on the mounting base 200. The mounting base 200 restricts the sliding frame 300 from sinking, thus ensuring the shaping quality of the concrete.

[0024] Furthermore, the fastener 400 includes: The fixing rod 410 is inclinedly mounted on the mounting base 200; The first sliding rod 420 is sleeved on the fixed rod 410 and slidably disposed on the fixed rod 410. After sliding along the fixed rod 410, the first sliding rod 420 moves closer to or further away from the mounting base 200. The first sliding rod 420 is slidably disposed on the vertical support rod 320. After the vertical support rod 320 slides, it drives the first sliding rod 420 to slide.

[0025] In this embodiment, to fix the sliding frame 300, a fixing rod 410 is designed on the mounting base 200. The fixing rod 410 is fixed obliquely on the mounting base 200. The first sliding rod 420 is sleeved on the fixing rod 410. After the vertical support rod 320 slides away from the mounting base 200, the first sliding rod 420 slides relative to the fixing rod 410. After the first sliding rod 420 slides relative to the fixing rod 410, one end of the first sliding rod 420 slides vertically on the vertical support rod 320, and the other end slides along the fixing rod 410. The horizontal sliding rod 310, the vertical support rod 320, the first sliding rod 420, and the fixing rod 410 form a triangular structure, which enhances the stability of the structure.

[0026] Furthermore, the vertical support rod 320 has a first sliding groove 330 and a first through groove 340. The first sliding groove 330 has a plurality of first openings 350. The first sliding groove 330 and the first through groove 340 are connected through the first openings 350. The first sliding rod 420 is slidably disposed in the first through groove 340. The fixing member 400 also includes: The first mounting plate 430 is slidably disposed within the first slide groove 330; The first inclined block 440 has several components and is slidably disposed in the first opening 350. After the first inclined block 440 extends out of the first opening 350, it prevents the first sliding rod 420 from sliding upward. After the first mounting plate 430 slides, it drives all the first inclined blocks 440 to slide into or out of the first opening 350. There is an inclination angle α between the first inclined block 440 and the vertical support rod 320. The inclination angle α is an acute angle. The first elastic element 450 has several parts, one end of which is disposed on the first mounting plate 430 and the other end of which is disposed on the first inclined block 440. The first elastic element 450 is used to provide the force for the first inclined block 440 to extend out of the first opening 350.

[0027] In this embodiment, to prevent one end of the first sliding rod 420 from sliding upward along the vertical support rod 320, i.e., along the first through groove 340, a first inclined block 440 is designed at the first opening 350. When the first sliding rod 420 slides down along the vertical support rod 320, it squeezes the first inclined block 440, causing the first elastic element 450 to contract. The first sliding rod 420 slides past the first inclined block 440 in sequence. When the vertical support rod 320 stops sliding, the first sliding rod 420 also stops sliding. During use, if the vertical support rod 320 shows a tendency to sink, the first elastic element 450 has already extended and reset, and the first inclined block 440 slides out of the first opening 350, preventing the other end of the first sliding rod 420 from sliding upward. This further ensures the stability of the triangular structure and prevents the vertical support rod 320 from sinking.

[0028] Furthermore, the fixing rod 410 has a second sliding groove 460 inside, and the second sliding groove 460 has several second openings 470 on both sides. The fixing member 400 also includes: There are two second mounting plates 480, both of which are slidably disposed in the second slide groove 460. After the two second mounting plates 480 slide, they move closer to each other or further away from each other. The second inclined block 490 has several units and is slidably disposed in the second opening 470. After the second mounting plate 480 slides, it drives all the second inclined blocks 490 to slide into or out of the second opening 470. The second elastic member 4100 has one end disposed on the second mounting plate 480 and the other end disposed on the second inclined block 490. The second elastic member 4100 is used to provide the force for the second inclined block 490 to slide out of the second opening 470.

[0029] In this embodiment, to prevent relative sliding between the first sliding rod 420 and the fixed rod 410, which would cause deformation of the included angle between the vertical support rod 320 and the horizontal sliding rod 310, a second opening 470 and a second inclined block 490 are designed on the fixed rod 410. When the first sliding rod 420 is completely fitted onto the fixed rod 410, the second inclined block 490 is completely hidden within the second opening 470. When the first sliding rod 420 and the fixed rod 410 slide relative to each other, the second opening 470 connects to the outside. Due to the action of the second elastic element 4100, the second inclined block 490 pops out of the second opening. 470. To prevent the first sliding rod 420 from sliding in the opposite direction after popping out, in this design, the horizontal sliding rod 310 has teeth 360. After the gear 600 rotates, it drives the two horizontal sliding rods 310 to slide in the opposite direction, so that the two vertical support rods 320 move closer or further apart. For each tooth 360 that the horizontal sliding rod 310 moves, the first sliding rod 420 must slide past a second inclined block 490. Similarly, one end of the first sliding rod 420 must slide past a first inclined block 440, ensuring that the vertical support rod 320 remains stable throughout the leveling process after sliding to the required position. In order to release the limitation of the second inclined block 490, this design incorporates a second mounting plate 480 inside the fixed rod 410. When the second mounting plates 480 move closer together, they drive all the second inclined blocks 490 to slide into the second opening 470, allowing the second sliding rod 4140 to slide in the opposite direction.

[0030] Furthermore, the second mounting plate 480 has a plurality of inclined grooves 4110, each inclined groove 4110 having a third opening 4120, the third openings 4120 of the two second mounting plates 480 being connected, and the fastener 400 further includes: The third inclined block 4130 has several units and is slidably disposed in the inclined groove 4110; The second sliding rod 4140 is located between the two second mounting plates 480. The third inclined block 4130 is slidably mounted on the second sliding rod 4140. After the second sliding rod 4140 slides, it causes the third inclined blocks 4130 of the two second mounting plates 480 to move closer to or further away from each other.

[0031] In this embodiment, in order to reduce the scraping range of the scraper 500, the first sliding rod 420 needs to slide in the opposite direction along the fixed rod 410. The second inclined block 490 prevents the first sliding rod 420 from sliding in the opposite direction. In order to make the two second mounting plates 480 move closer to each other or further away from each other, this solution designs an inclined groove 4110 on the second mounting plate 480. After the second sliding rod 4140 slides, it drives the third inclined block 4130 to slide. The second groove 460 limits the second mounting plate 480, so that the second mounting plates 480 can only move closer to each other or further away from each other. After the third inclined block 4130 slides along the inclined groove 4110, due to the limitation of the second groove 460, it drives the two second mounting plates 480 to move closer to each other or further away from each other, thus releasing the limitation on the first sliding rod 420.

[0032] Furthermore, rack 100 includes: Base 110; The first bracket 120 is rotatably mounted on the base 110; The second bracket 130 is rotatably mounted on the first bracket 120, and the mounting base 200 is slidably mounted on the first bracket 120 and the second bracket 130.

[0033] Furthermore, it also includes: The telescopic component 140 is rotatably mounted on the base 110 at one end and rotatably mounted on the first bracket 120 at the other end. When the telescopic component 140 extends or retracts, it drives the first bracket 120 to rotate.

[0034] Furthermore, the lateral sliding rod 310 has teeth 360 and also includes: Gear 600 is rotatably mounted on mounting base 200. The teeth 360 of the two transverse sliding rods 310 are engaged with gear 600. After gear 600 rotates, it drives the two transverse sliding rods 310 to slide in opposite directions.

[0035] Furthermore, the mounting base 200 is detachably mounted on the base 110.

[0036] In this embodiment, to enable the device to be used in small rooms and to be lightweight and portable, the frame 100 is designed as a foldable structure, while the sliding frame 300 and the frame 100 are designed as detachable structures. In use, the sliding frame 300 and the frame 100 are assembled. After use, the sliding frame 300 is disassembled, and the gear 600 is rotated to store the sliding frame 300. Finally, the frame 100 is folded up. This device is not only lightweight and portable, but also has the advantage of low cost.

[0037] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.
