[0025] EMBODIMENT

[0026] Please refer to Figures 1-6 In the embodiment, a floor leveling device is provided, which comprises a fixed frame 1 and a moving frame 2. The rear side of the fixed frame 1 is provided with two fixed assemblies 4, which are symmetric about the center of the fixed frame 1 and can adjust the distance. The fixed frame 1 is fixedly installed with the support beam through the fixed assemblies 4, and the fixed assemblies 4 that can adjust the distance can adapt to support beams of different sizes, thereby improving the adaptability of the leveling device and making installation more convenient.

[0027] The front side of the fixed frame 1 is connected with the moving frame 2 through a plurality of springs 3, and limiting assemblies 6 are arranged on the left and right sides of the fixed frame 1 and the moving frame 2. The limiting assemblies 6 can limit the moving frame 2 when it is pressed by the floor, avoiding the moving frame 2 from deviating only by the action of the springs 3, and the leveling effect is better. In addition, the limiting assemblies 6 are of a convenient dismounting structure, which can replace the springs 3 after long-term use after dismounting, avoiding the problem of reduced elasticity of the springs 3 after long-term use.

[0028] Specifically, the rear side wall of the fixed frame 1 is provided with two inner grooves 11, and the inner grooves 11 are symmetrically distributed upward and downward. Each inner groove 11 is provided with a fixing assembly 4. The fixing assembly 4 comprises a bidirectional screw rod 41. The bidirectional screw rod 41 is located in the inner groove 11 and is rotationally connected with the inner groove 11. One end of the bidirectional screw rod 41 extends out of the inner groove 11 and is provided with a handle 42. Two sliding seats 43 are sleeved on the bidirectional screw rod 41. The sliding seats 43 are located in the inner groove 11 and are slidingly connected with the inner groove 11. The outer side wall of the sliding seat 43 is provided with a mounting plate 44. The mounting plate 44 is provided with a fixing hole 45. According to different sizes (widths) of the supporting beam, the handle 42 is rotated to drive the bidirectional screw rod 41 to rotate, and then the two sliding seats 43 are close to or away from each other in the inner groove 11 to realize distance adjustment. The distance between them is adapted to the supporting beam. Then the mounting plate 44 can be attached to the two corresponding side walls of the supporting beam. The mounting plate 44 and the supporting beam are fixed by bolts to complete the installation of the leveling device.

[0029] A plurality of grooves 5 are arranged on one side of the movable frame 2 and the fixed frame 1 which are close to each other. The grooves 5 on the two frames correspond to each other in front and back. The spring 3 is arranged in the front and back corresponding grooves 5. The spring 3 is in a compressed state and is not fixed with the inner wall of the groove 5. The purpose is that after the movable frame 2 and the fixed frame 1 are disassembled, the spring 3 can be conveniently replaced. It can be taken out from the groove 5 and a new spring 3 can be reinstalled.

[0030] In order to achieve the above purpose, the limiting assembly 6 is arranged in a structure convenient for disassembly. At the same time, the limiting assembly 6 can guide and limit the movable frame 2 when it is pressed by the platform plate to avoid deviation. The forklift slowly approaches and presses the multiple stacked and irregular platform plates to the movable frame 2 to align them. After the movable frame 2 is pressed, it will move to one side of the fixed frame 1 and press the spring 3. After the platform is aligned, it is away from the movable frame 2, and then it returns to its original state.

[0031] The limiting assembly 6 comprises a fixed seat one 61 and a fixed seat two 62. The fixed seat one 61 and the fixed seat two 62 are arranged on the side walls of the movable frame 2 and the fixed frame 1 respectively. A screw hole 63 is arranged in the fixed seat one 61. A limiting hole 64 is arranged in the fixed seat two 62. A sliding rod 65 is slidingly connected in the limiting hole 64. The two ends of the sliding rod 65 are provided with screw rods 66. One of the screw rods 66 is screwedly installed in the screw hole 63. The other screw rod 66 is screwedly connected with a nut 67. When the movable frame 2 moves, the sliding rod 65 which is screwedly connected with the movable frame 2 moves in the limiting hole 64. When the movable frame 2 is supported by the spring 3 to move outward, the nut 67 has a limiting effect to avoid the movable frame 2 moving too far.

[0032] When the spring 3 needs to be replaced, the nut 67 is unscrewed, then the moving frame 2 is pulled, so that the slide rod 65 moves, and the distance between the moving frame 2 and the fixed frame 1 is increased, the spring 3 is taken out from the two grooves 5, and the new spring 3 is placed, then the moving frame 2 is reset and the nut 67 is installed.

[0033] The fixing assembly 4 in the utility model can realize the adjustment of the distance between the two mounting plates 44 through the mutual cooperation of the bidirectional screw rod 41, the sliding seat 43 and the mounting plate 44, thereby adapting to different sizes of the supporting beam, improving the adaptability of the leveling device and increasing the practicality.

[0034] In addition, the spring 3 is directly placed between the two grooves 5 and is limited through the limiting assembly 6, so that the moving frame 2 is prevented from moving too long, the spring 3 is kept in a compressed state all the time, meanwhile, the limiting assembly 6 is connected through screw threads, can be conveniently disassembled, and also realizes the convenient replacement of the spring 3 after long-time use, solves the problem that the elasticity of the spring 3 is weakened after long-time use, and improves the service life of the leveling device.
