Description

Technical Field

[0001] The utility model relates to a ground leveling device, in particular to a ground leveling device with adjustable height. Background Art

[0002] Before laying ceramic tiles on the ground using the thin-tack process, it is necessary to do a good job of leveling the ground to ensure the flatness of the ground. This is to avoid hollowing and cracking problems caused by the thickness of the adhesive material and the different forces applied to the material during construction when laying tiles later due to insufficient ground flatness.

[0003] At present, the existing technology of making ash cakes and punching ribs is used for leveling. Cement mortar is used to make ash cakes at a certain distance on the base surface, and then cement mortar is used to make ash strips to connect the ash cakes, and the heights of the ash cakes and ash strips are made to be consistent. During the subsequent pouring, the ash cakes and ash strips are used to control the mortar thickness, thereby controlling the flatness and verticality of the ground. However, after the ash cakes and ash strips are made and solidified, their heights are fixed and cannot be adjusted according to the construction requirements. They are inconvenient to use, and the production of ash cakes takes a long time. After each process is completed, it is necessary to wait until the previous process is completed before the next process can be carried out, which prolongs the construction time.

[0004] Therefore, there is an urgent need to provide a ground leveling device with adjustable height. Utility Model Content

[0005] In order to overcome the shortcomings of the current leveling process using mortar cakes and rib punching, in which the height of the mortar cakes is fixed after they are made and solidified, and cannot be adjusted according to construction requirements, making them inconvenient to use, and the mortar cakes are time-consuming to make, and each process must wait until the previous process is completed before the next process can be carried out, thus prolonging the construction time. The utility model provides a ground leveling device with adjustable height.

[0006] In order to solve the above-mentioned problem, the utility model adopts the following technical scheme: a ground leveling device with adjustable height, comprising a base plate, on which are fixedly connected symmetrically distributed mounting seats, a rotating block is rotatably arranged on the mounting seat, a screw is threadedly arranged on the mounting seat, the screw passes through the rotating block and is threadedly matched with the screw, a connecting plate is installed on the screw, a guide rod is installed on the connecting plate, a first nut is threadedly arranged on the screw and the guide rod, a level ruler is installed on the guide rod, and a scale ruler is embedded on the level ruler.

[0007] Furthermore, the screw is in a vertical state.

[0008] Furthermore, a mounting plate is fixedly connected to the level, and a second nut is provided on the mounting plate.

[0009] Furthermore, a connecting rod is threadedly arranged on the level ruler, and the connecting rod is threadedly connected to the scale.

[0010] Furthermore, an X-axis horizontal bubble measuring tube is installed on the level ruler.

[0011] Furthermore, a Y-axis horizontal bubble measuring tube is installed on the bottom plate.

[0012] Compared with the prior art, the utility model has the following technical effects: 1. By twisting the rotating block, the screw can be rotated upward to adjust the level ruler to a suitable height to contact the ground for flatness measurement according to the construction requirements. It is easy to use and helps to improve the leveling efficiency.

[0013] 2. The connecting plate, the guide rod and the level ruler can be removed by unscrewing the first nut, thereby reducing the overall volume of the device for portability and facilitating subsequent maintenance.

[0014] 3. The level ruler can be fixed to the ground by using the second nut in combination with the bolt to prevent the level ruler from moving and affecting subsequent data measurement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-Figure 4 A floor leveling device with adjustable height comprises a base plate 1, on which a Y-axis horizontal bubble measuring tube 10 is installed. When the device is used, the Y-axis horizontal bubble measuring tube 10 is used to correct the placement position of the base plate 1 to ensure that the base plate 1 is placed horizontally. Two mounting seats 2 that are symmetrically distributed on the top of the base plate 1 are fixedly connected by welding. A rotating block 201 is rotatably provided on the upper part of the mounting seat 2. A screw rod 3 is threadedly provided on the mounting seat 2. The screw 3 is in a vertical state, and the screw rod 3 passes through the rotating block 201 and is threadedly matched with it. A connecting plate 4 is installed on the screw 3, and a guide rod 6 is installed on the connecting plate 4. The screw 3 and the guide rod 6 are both threadedly provided with a first nut 5. The connecting plate 4 can be screwed by the first nut 5. 4 and the guide rod 6 are assembled on the screw rod 3, a level ruler 7 is installed at the bottom end of the guide rod 6, and an X-axis horizontal bubble measuring tube 9 is installed on the level ruler 7. When the level ruler 7 measures the ground, the bubble position in the X-axis horizontal bubble measuring tube 9 is observed to accurately and quickly measure the flatness of the ground. If the bubble is centered, it means that the ground is flat, and if the bubble is biased to both sides, it means that the ground is not flat enough. A scale ruler 8 is embedded in the middle of the level ruler 7. The scale ruler 8 is used to read the bubble position to judge the horizontal degree of the ground. Ten horizontally arranged connecting rods 703 are threadedly arranged in the middle of the level ruler 7. The ten connecting rods 703 are threadedly connected to the adjacent scale rulers 8. The connecting rods 703 are twisted to separate them from the scale ruler 8, and the scale ruler 8 can be removed from the level ruler 7.

[0023] When in use, the operator fixes the base plate 1 to the ground, and then turns the rotating block 201 to rotate the screw 3 upward to adjust the level ruler 7 to a suitable height in contact with the ground according to the construction requirements to measure the flatness. After the measurement is completed, the first nut 5 is unscrewed to remove the connecting plate 4, the guide rod 6, and the level ruler 7, thereby reducing the overall volume of the device for carrying and facilitating subsequent maintenance.

[0024] Example 2

[0025] Based on Example 1, please refer to Figure 3 The lower part of the level ruler 7 is fixedly connected with two mounting plates 701 which are symmetrically distributed front and back by welding, and the mounting plates 701 are provided with four second nuts 702 which are arranged horizontally.

[0026] After the level ruler 7 is leveled, the second nut 702 can be used in conjunction with the bolt to fix the level ruler 7 to the ground, so as to prevent the level ruler 7 from moving and affecting subsequent data measurement.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
