[0022] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, a concrete vibratory leveling ruler includes: a vibrator 1, which is driven by gasoline; a support rod 2 connected to the top of the vibrator 1; a base ruler 3 fixed to the bottom of the support rod 2; extension rods 4 slidably connected to both ends of the support rod 2, the extension rods 4 and the support rod 2 being connected by positioning pins 41; a movable rod 5 slidably connected to the end of the extension rods 4, the extension rods 4 being able to move up and down relative to the movable rods 5; an extension ruler 6 detachably connected to the side wall of the base ruler 3; and a transmission mechanism 7 connecting all the extension rulers 6 and the base ruler 3, the transmission mechanism 7 being connected to the bottom of the vibrator 1.

[0024] This device is used during concrete paving in road maintenance and repair. Road repair only involves excavating and rebuilding a portion of the road; therefore, both ends of the repaired section remain as usable roads. The repaired section is lower than the normal road surface.

[0025] A handle 21 is fixedly connected to the middle of the support rod 2. The support rod 2 is moved by pushing and pulling the handle 21, which in turn moves the device. The direction of movement of the device can also be controlled by the handle 21. For repair areas that require turning, the device can be turned to vibrate and level the concrete.

[0026] The extension rod 4 is used to increase the length of the extension rod 4, so that the device can be applied to repair areas of different widths, increasing adaptability. The end of the support rod 2 is provided with multiple first connection holes 22, which are evenly distributed. There is no base ruler 3 below the first connection hole 22. The extension rod 4 slides along the support rod 2 where the first connection hole 22 is located, thereby adjusting the position of the extension rod 4 and ensuring that one end of the extension rod 4 is on the road in normal use.

[0027] like Figure 2As shown, one end of the extension rod 4 is provided with a second connecting hole 42. The first connecting hole 22 and the second connecting hole 42 have the same diameter. During the sliding process of the extension rod 4, the second connecting hole 42 coincides with the first connecting hole 22 in sequence. After the first connecting hole 22 and the second connecting hole 42 coincide, it is convenient to fix the position of the extension rod 4.

[0028] The bottom of the positioning pin 41 has two inserts 411, the distance between the two pins being the same as the spacing between adjacent first connecting holes 22. The two inserts 411 are inserted into the overlapping positions of the first connecting hole 22, the second connecting hole 42, and the adjacent first connecting hole 22, respectively. The top of the positioning pin 41 has a pull ring 412. After the position of the extension rod 4 is adjusted, the positioning pin 41 is inserted to restrict the relative sliding between the support rod 2 and the extension rod 4. The insertion of the inserts 411 of the positioning pin 41 into the two first connecting holes 22 can effectively prevent the positioning pin 41 from falling off due to vibration.

[0029] The base ruler 3 is L-shaped, and its inner wall and bottom are connected to the vibrator 1. When the vibrator 1 is started, it drives the base ruler 3 to vibrate together. The bottom surface of the base ruler 3 contacts the surface of the concrete. After the base ruler 3 vibrates, it flattens the surface of the concrete, so that the concrete is laid flat on the repair area.

[0030] The movable rod 5 is perpendicular to the extension rod 4. Universal wheels 51 are provided at both ends of the movable rod 5. The movable rod 5 assists in the movement of this device. A threaded rod 52 is located in the middle of the movable rod 5, passing through the extension rod 41. An adjusting nut 53 is screwed onto the threaded rod 52, supporting the bottom of the extension rod 4. During concrete paving, the height of the concrete layer needs to be controlled. By rotating the adjusting nut 53, the height of the support rod 2 can be changed, further altering the height of the base ruler 3. The bottom surface of the base ruler 3 is the designed top surface of the concrete layer. During use, there is no need to manually pull the handle 21 to control the height of the base ruler 3. Furthermore, the movable rod 5 assists in movement, reducing effort and thus improving construction efficiency and quality.

[0031] The extension ruler 6 connects to the base ruler 3, ensuring that the lengths of both are adapted to the width of the repair area. The extension ruler 6 is available in multiple length models, allowing for easy selection and combination based on the repair area during actual construction. For example... Figure 3 As shown, one end of the extension ruler 6 is provided with a insert 61, and the other end of the extension ruler 6 and the end of the base ruler 3 are provided with a locking groove 62. The insert 61 is inserted into the locking groove 62. The side wall of the support rod 2 is provided with a connecting groove. The top of the extension ruler 6 is slidably connected to the connecting groove. The connecting groove allows the extension ruler 6 to move along a specific route, ensuring that the side wall of the extension ruler and the side wall of the base ruler 3 can fit together.

[0032] The front end of the insert 61 is rotatably connected to a limiting plate 611. After the insert 61 is inserted into the locking groove 62, the limiting plate 611 is perpendicular to the insert 61 and fits against the side wall of the locking groove 62. In use, the top of the extension ruler 6 is inserted into the connecting groove, and then slid towards the locking groove 62. When the base ruler 3 and the side wall of the extension ruler 6 are tightly fitted, the limiting plate 611 rotates downward under the action of gravity, and the limiting plate 611 fits against the end face of the locking groove 62, preventing the extension ruler 6 from moving backward, thereby fixing the base ruler 3 and the extension ruler 6 tightly.

[0033] The transmission mechanism 7 includes connecting blocks 71, a first transmission rod 72, and a second transmission rod 73. Connecting blocks 71 are provided on the extension ruler 6 and the base ruler 3. The connecting blocks 71 on the base ruler 3 are located at both ends of the base ruler 3, and the connecting blocks 71 on the extension ruler 6 are located in the middle of the extension ruler 6. The first transmission rod 72 passes through and connects the two connecting blocks 71 on the base ruler 3, and the second transmission rod 73 passes through the connecting blocks 71 on the extension ruler 6. The second transmission rod 73 is screwed to the side wall of the first transmission rod 72. The first transmission rod 72 passes through the vibrator 1. After the first transmission rod 72 and the second transmission rod 73 are screwed together, they become a single unit. When the vibrator 1 is started, the first transmission rod 72 and the second transmission rod 73 transmit vibration to the connecting blocks 71, further strengthening the vibration at the edges and allowing the edges of the repair area to be quickly leveled.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
