DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples.

[0024] In one embodiment, as shown in Figures 1-5 A curbstone carrying trolley comprises a main support 1, an axle support 2, a lever structure and a clamping mechanism, the axle support 2 is fixedly arranged on both sides of the main support 1, the bottom end of the axle support 2 is fixedly provided with a driven shaft 3, the driven shaft 3 is rotatably provided with a wheel 4, the rear end of the main support 1 is fixedly provided with the lever structure for lifting the main support 1, and the bottom of the main support 1 is fixedly provided with the clamping mechanism.

[0025] In one embodiment, as shown in Figure 2 The lever structure comprises a tripod 5 fixedly arranged at the rear end of the main support 1, the end of the tripod 5 is fixedly provided with a power arm 6, and the end of the power arm 6 is fixedly provided with a rubber handle 7.

[0026] The main support 1 can be lifted by holding the rubber handle 7 to press down the power arm 6, and using the lever principle of the tripod 5, with the wheel 4 as the fulcrum. The rubber handle 7 is arranged to improve the comfort of the operator holding, and to prevent slipping during use. The wheel 4 is connected to the main support 1 through the driven shaft 3 to ensure the stability of the fulcrum.

[0027] In one embodiment, as shown in Figure 3 and Figure 5 The clamping mechanism comprises a rotating support 8 fixedly arranged at the bottom of the main support 1, the inner side of the rotating support 8 is rotatably provided with a rack 9, the outer side of the rack 9 is slidably provided with a clamping support 10, the bottom end of the rack 9 is fixedly provided with a limiting block 11, the inner wall of the clamping support 10 is rotatably provided with a gear 13 through a rotating rod 12, the gear 13 is fixedly provided with a clamping arm 14, the clamping arm 14 is slidably provided with an adjusting mechanism for adapting to curbstones of different sizes, and the inner wall of the clamping support 10 is provided with a sliding groove matched with the rack 9. The adjusting mechanism comprises an adjusting support 15 slidably arranged on the clamping arm 14, the clamping arm 14 and the adjusting support 15 are both provided with a positioning hole 16, the bottom of the positioning hole 16 is fixedly provided with an anti-skid unit, the anti-skid unit comprises a clamping plate 17 fixedly arranged at the bottom of the positioning hole 16, the clamping surface of the clamping plate 17 is provided with an anti-skid pad 18, the material of the anti-skid pad 18 is natural rubber, and the adjusting support 15 is fixed in the positioning hole 16 on the clamping arm 14 through a fixing bolt.

[0028] By lifting the main support 1, the rack 9 moves upward, causing it to slide up and down inside the clamping support 10. The rack 9 meshes with the gear 13, causing the clamping arm 14 to open and close. Then, the adjusting support 15 slides on the clamping arm 14 and is fixed through the positioning hole 16, thus controlling the clamping range. Combined with the anti-slip pad 18, the curbstone is clamped. The curbstone exerts pressure on the clamping arm 14 due to gravity, forcing the clamping arm 14 to fit tightly against the curbstone surface. This contact force is converted into friction, preventing the curbstone from slipping. The operator can then push the trolley for transport. This makes operation simple and convenient, while saving transportation costs. The rotating support 8 ensures the clamping mechanism remains vertically downward, facilitating clamping using the lever principle. The limiting block 11 prevents the rack 9 from detaching from the clamping support 10 when sliding upward. Simultaneously, the limiting block 11 limits the clamping support 10, keeping the clamping arm 14 open, allowing the operator to align the clamping plate 14 on the clamping arm 14 with the curbstone.

[0029] The above embodiment discloses a curbstone transport trolley. By gripping the rubber handle 7 and pressing down on the power arm 6, the main support 1 can be lifted using the lever principle of the tripod 5 and the wheel 4 as a fulcrum. Lifting the main support 1 causes the rack 9 to move upwards, allowing it to slide up and down inside the clamping bracket 10. The rack 9 meshes with the gear 13, causing the clamping arm 14 to open and close. Then, the adjusting bracket 15 slides on the clamping arm 14 and is fixed through the positioning hole 16, thereby controlling the clamping range. With the help of the anti-slip pad 18, the curbstone is clamped. The curbstone exerts pressure on the clamping arm 14 due to gravity, forcing the clamping arm 14 to fit tightly against the curbstone surface. This contact force is converted into friction, preventing the curbstone from slipping. The operator can then push the trolley for transport. This makes operation simple and convenient, while saving on transportation costs.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
