[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-7 This utility model discloses a road leveling device, including a mounting plate 1, a sliding table 2 slidably mounted on the mounting plate 1, a locking component 3 provided on the side of the sliding table 2 away from the mounting plate 1, and a docking sleeve 7 installed on the side wall of the mounting plate 1. In use, the handle can be inserted into the docking sleeve 7, and the worker can level the road by holding the handle.

[0025] In one embodiment, the device further includes a scraper 4, which is mounted on the side of the slide table 2 near the locking assembly 3. The locking assembly 3 includes a housing 31 and an elastic pin disposed in the housing 31 and capable of sliding laterally. The scraper 4 has a slot, and the elastic pin can be inserted into the slot after being triggered to lock the scraper 4. It can also be triggered again to unlock the scraper 4.

[0026] In practice, in the initial state, the elastic pin is inserted into the slot, which positions the scraper 4 with the locking component 3. The operator holds the handle and makes the scraper 4 contact the road surface, and then pushes the device to move the scraper 4 on the road surface to level it. When it is necessary to remove the scraper 4, the elastic pin is operated to trigger it, so that it can leave the slot and release the locking component 3 from limiting the scraper 4, so that the scraper 4 can leave the bottom of the mounting plate 1. This method replaces the bolt fixing method and can effectively replace the scraper 4.

[0027] In one embodiment, the elastic pin includes an L-shaped pin 32 that is slidably installed inside the housing 31. The opposite sides of the pin 32 pass through the top and bottom of the housing 31 and extend outward. A push rod 33 is slidably installed on the inner side of the housing 31. A spring 34 is installed on the inner side of the housing 31 that contacts the side of the push rod 33 away from the pin 32. A locking groove 35 is provided on the scraper 4.

[0028] In practice, the spring 34 can push the push rod 33 and the pin 32 to move laterally within the housing 31, so that the pin 32 is inserted into the locking groove 35. Specifically, the operator pushes the pin 32 towards the side closer to the spring 34, so that the scraper 4 can contact the housing 31 without being blocked by the pin 32. At this time, the pin 32 will be inserted into the locking groove 35. Then, the operator releases the pin 32, at which point the spring 34 squeezes the pin 32, causing it to be further inserted and positioned in the locking groove 35, so that the scraper 4 can be stably connected to the locking assembly 3, which is convenient for subsequent leveling operations.

[0029] In one embodiment, a threaded rod 5 is screwed onto the inner side of the mounting plate 1, and a positioning component 6 is provided on the scraper 4. The positioning component 6 is located on the opposite side of the scraper 4 and the threaded rod 5. The positioning component 6 can detachably connect the threaded rod 5 and the scraper 4 without affecting the rotation of the threaded rod 5.

[0030] With this design, when the positioning component 6 is connected to the threaded rod 5, rotating the threaded rod 5 allows it to move within the mounting plate 1, thereby changing the distance between the mounting plate 1 and the positioning component 6. This makes it easier for workers to use the tool according to the actual situation, preventing the worker's grip on the handle from being too close to the ground and causing their hands to get covered in cement or other materials. When it is necessary to remove the scraper 4, it can be removed by adjusting the positioning component 6 so that it is not connected to the threaded rod 5.

[0031] In one embodiment, the positioning component 6 includes a detachable mounting sleeve 61 mounted on the scraper 4. The mounting sleeve 61 has a through hole on its side wall. The positioning component 6 also includes a rotating column 62 rotatably mounted on the threaded rod 5 near one end of the scraper 4. An elastic pin 63 is slidably provided on the inner side of the rotating column 62. The rotation of the threaded rod 5 inside the scraper 4 can cause the rotating column 62 to move towards the inner side of the mounting sleeve 61. The elastic pin 63 can be inserted into the through hole when the rotating column 62 is inside the mounting sleeve 61 and aligned with the through hole.

[0032] In practice, the elastic pin 63 consists of a spring body and a pin shaft. After the operator presses it into the rotating column 62, the rotating column 62 can be inserted into the mounting sleeve 61. When the rotating column 62 is inside the mounting sleeve 61 and the elastic pin 63 is aligned with the through hole, the pin shaft can be inserted into the through hole under the push of the spring body, so that the threaded rod 5 can continue to rotate and adjust while temporarily connecting with the scraper 4. Disassembly can be performed by reversing the above steps. The elastic pin 63 mentioned above is common knowledge in the field, so its specific structural composition and working principle will not be described in detail.

[0033] In one embodiment, the scraper 4 has an installation groove 9, and the mounting plate 1 has a baffle 8 that can be slidably provided. The side of the baffle 8 near the mounting plate 1 can be inserted into the installation groove 9, and the length of the baffle 8 is greater than the length of the scraper 4.

[0034] With this design, when leveling using this device, the baffle 8 can prevent material from contacting the locking component 3 and the positioning component 6, thereby ensuring that the mounting groove 9 and the positioning component 6 will not be affected by material contamination and thus will not affect their normal use. Since the baffle 8 can be detached from the mounting groove 9, it will not affect the disassembly and replacement of the scraper 4.

[0035] In one embodiment, the device further includes a sliding assembly 10, which includes a housing 101 mounted on a mounting plate 1. A mounting block 102 is slidably mounted on the housing 101 and is connected to a baffle 8.

[0036] This design allows the baffle 8 to be inserted into or detached from the mounting slot 9 according to the corresponding movement trajectory, thereby improving the ease of operation.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0039] Additionally, "multiple" refers to two or more.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
