[0004] However, it also has the following problems: when the ruler pad is placed on the ground, if the soil is relatively loose, the support legs of the ruler pad are prone to displacement, causing the ruler pad to flip over and resulting in inaccurate positioning. In addition, the ruler pad is not easy to store and takes up a lot of space. Utility Model Content

[0005] To address the problems existing in the prior art, a non-slip leveling rod pad for hydrological slope measurement is provided. This device is easy to operate, effectively fixes the rod pad on the slope, and its outriggers can penetrate deep into the soil, improving the pad's stability and preventing slippage, thus facilitating the fixation of the leveling rod.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] This utility model proposes an anti-slip leveling rod pad for hydrological slope measurement, including a rod pad. The upper surface of the rod pad is provided with fixing points for fixing the leveling rod. The lower surface of the rod pad is fixedly connected to a support leg.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model is equipped with support legs. After the support legs penetrate into the soil, the pressure rod is pressed down, causing the entire leveling pad to be pressed down further. The pressure rod can drive several limiting rods to open simultaneously. At this time, an acute angle is formed between the limiting rods and the support legs. At the same time, the locking rod slides into the locking groove, which can lock the rotating shaft. It is easy to operate and can effectively fix the leveling pad on the slope.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] Example 1

[0029] like Figures 1-4 As shown in the figure, this embodiment proposes an anti-slip leveling rod pad for hydrological slope measurement, including a rod pad 1. The upper surface of the rod pad 1 is provided with a fixing point 10 for fixing a leveling rod 20. The leveling rod 20 is made of ferromagnetic material, and the fixing point 10 is specifically a conical magnet that attracts the leveling rod 20, making it easier for the leveling rod 20 to be better fixed on the fixing point 1.

[0030] The lower surface of the ruler pad 1 is fixedly connected to a support leg 3, and the support leg 3 is rotatably connected to several limiting rods 17. The support leg 3 is slidably connected to a pressure rod 5, and the pressure rod 5 is fixedly connected to a top ball 15 that cooperates with the limiting rod 17. The top ball 15 is located inside the limiting rod 17. When the pressure rod 5 descends, it can drive several limiting rods 17 to rotate outward simultaneously.

[0031] The outrigger 3 is rotatably connected to a pivot, and the bottom end of the limiting rod 17 is fixedly sleeved on the pivot. Several pivots are located at the same horizontal height, and several limiting rods 17 are located at the same height. The top ball 15 is designed to facilitate the limiting rod 17 to rotate outward when the pressure rod 5 moves downward. At the same time, the top of the limiting rod 17 is provided with an inclined surface. The inclined surface facilitates the top ball 15 to slide between the limiting rod 17 and the pressure rod 5, thereby better driving the limiting rod 17 to rotate.

[0032] The friction between the pivot and the support leg 3 is appropriate, and the magnitude of the friction is sufficient to keep the limiting rod 17 in a vertical state. In the initial state, the limiting rod 17 is located inside the support leg 3, or the outer surface of the limiting rod 17 is flush with the support leg 3, so that the support leg 3 can penetrate deeper into the soil.

[0033] The rotating shaft has a locking groove 19, and the pressure rod 5 is fixedly connected to a locking rod 16 that can slide into the locking groove 19. When the limiting rod 17 rotates to a suitable angle, the locking rod 16 slides into the locking groove 19, and the limiting rod 17 cannot rotate freely. At this time, the angle of the limiting rod 17 can make the inclined surface at the upper end of the limiting rod 17 parallel to the ruler pad 1, thereby further increasing the contact area and better achieving anti-slip.

[0034] The ruler pad 1 is fixedly connected to the fixed cylinder 4, and the pressure rod 5 passes through the fixed cylinder 4 and is slidably connected to the fixed cylinder 4. The fixed cylinder 4 is set to guide and limit the movement of the pressure rod 5, so that the pressure rod 5 can only move in the vertical direction.

[0035] The fixed cylinder 4 is slidably connected to a ratchet 7, which is connected to the fixed cylinder 4 via a spring 8. The pressure rod 5 has a slot 14 that mates with the ratchet 7, and one end of the ratchet 7 extends out of the fixed cylinder 4.

[0036] Spring 8 is sleeved on ratchet 7. One end of spring 8 is connected to ratchet 7, and the other end of spring 8 is connected to fixed cylinder 4. The elastic force of spring 8 can keep ratchet 7 and slot 14 in a coordinated state. The shape characteristics of ratchet 7 and slot 14 make the pressure rod 5 only able to move downward and not upward.

[0037] After the support leg 3 penetrates into the soil, the pressure rod 5 is pressed down, causing the entire leveling pad 1 to be pressed down further. The pressure rod 5 can drive several limiting rods 17 to open simultaneously. At this time, an acute angle is formed between the limiting rods 17 and the support leg 3. At the same time, the locking rod 16 slides into the locking groove 19, which can lock the rotating shaft. The operation is convenient and can effectively fix the leveling pad 1 on the slope. The support leg 3 can penetrate into the soil, which improves the fixing effect of the leveling pad 1, better prevents the leveling pad from slipping, and facilitates the fixing of the leveling rod.

[0038] The lower surface of the ruler pad 1 is fixedly connected to the rotating base 11, and the rotating base 11 is rotatably connected to the handle 12. The lower surface of the ruler pad 1 is also fixedly connected to the magnet 13, which has an attractive effect on the handle 12. By rotating the handle 12, it is easy to carry the ruler pad 1 as a whole. The magnetic force of the magnet 13 is suitable enough to fix the handle 12.

[0039] The ruler pad 1 is slidably connected to the extension plate 2, and the ruler pad 1 is threadedly connected to the bolt 9. After the bolt 9 is tightened, it can abut against the extension plate 2. The extension plate 2 is fixed with supporting structures such as the support leg 3, the limiting rod 17 and the pressure rod 5. The extension plate 2 can better realize the storage of the ruler pad 1.

[0040] The outer wall of the outrigger 3 is fixedly connected with several toothed blocks 6. The toothed blocks 6 are in contact with the surface of the soil to play a role in preventing slippage. The bottom end of the pressure rod 5 is fixedly connected with a plug 18 that can slide out of the outrigger 3. The plug 18 and the outrigger 3 are slidably connected.

[0041] When the pressure rod 5 is pressed down, causing the limiting rod 17 to open, the plug 18 can penetrate deep into the soil. When the limiting rod 5 is released, the plug 18 returns to its original position and moves back into the support leg 3, creating space below the support leg 3. This allows the soil below the limiting rod 17 to flow better when the limiting rod 17 is reset, making it easier for the limiting rod 17 to rotate downwards and for the support leg 3 to be pulled out as a whole.

[0042] The specific working process is as follows: Insert the outrigger 3 into the soil of the slope, press down the pressure rod 5, and the pressure rod 5 drives the entire ruler pad 1 to descend further. At the same time, the pressure rod 5 drives several limit rods 17 to open simultaneously through the top ball 15. Finally, the locking rod 16 slides into the locking groove 19 to limit the rotation angle of the limit rod 17. During this process, the plug 18 moves out of the outrigger 3 and enters the soil downward. The toothed block 6 contacts the soil surface. Under the action of the ratchet 7, the pressure rod 5 can only move downward and cannot be pulled upward.

[0043] When disassembly is required, pull out the ratchet 7 to release the limit on the pressure rod 5. At this time, the pressure rod 5 can be pulled out, the plug 18 moves into the support leg 3, and the locking rod 16 releases the limit on the rotating shaft. At this time, the limiting rod 17 can rotate freely. By pulling the ruler pad 1 upward, the limiting rod 17 rotates downward. After the plug 18 is reset, a certain space is formed under the support leg 3, which facilitates the better rotation of the limiting rod 17 and allows the ruler pad 1 to be moved out.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
