[0030] In the prior art, the braking of the food truck is achieved through the cooperation of the slider and the slide groove. However, during the process of pushing the food truck, it is very difficult to exactly insert the slider into the slide groove. If there is still a distance between the slider and the slide groove, the food truck needs to be pushed for a certain distance again, which affects the use of the food truck. Secondly, the braking of the food truck in the prior art is simply to stop the wheels from rolling, and it is not convenient to assist the food truck after it stops moving, making it easy for the food truck to be unstable when it stops running. Therefore, through research, a food truck braking mechanism and a food truck are provided. When in use, by rotating the double-headed gear, the double-headed gear meshes with the two side gear threes, the gear three drives the rotating rod to rotate, the gear two and the gear one mesh, the gear one drives the bi-directional lead screw to rotate, and the connecting plate drives the brake block to clamp both sides of the movable wheel, achieving the purpose of braking. The operation is simple, and there is no need to observe the position of the food truck moving, and the food truck can be stopped at the current position, thus solving the above defects.

[0031] The following will, with reference to the accompanying drawings, elaborate on some implementation modes of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0032] Please refer to Figures 1 to 8 , an embodiment of the present utility model provides a food truck braking mechanism, including a pair of frames 1. Bottom plates 3 are arranged on the lower sides of the pair of frames 1. Slide grooves 31 are symmetrically opened on the bottom plates 3. Two connecting plates 5 are respectively slid at both ends of the slide groove 31. A brake block 51 is connected to the lower side of the connecting plate 5. The internal shape of the brake block 51 is adapted to the shape of the movable wheel 14 for braking the movable wheel 14.

[0033] Therefore, the two brake blocks 51 are respectively located on both sides of the movable wheel 14, and the movable wheel 14 is installed on the lower side of the bottom plate 3. When the connecting plate 5 drives the brake block 51 to fit with the movable wheel 14, a braking effect is generated.

[0034] In order to enable the connecting plate 5 to move automatically, a bi-directional lead screw 6 is rotatably arranged in the slide groove 31. Both ends of the bi-directional lead screw 6 are respectively threadedly connected to the two connecting plates 5. The thread directions on the left and right sides of the bi-directional lead screw 6 are opposite to each other in central symmetry. When the bi-directional lead screw 6 rotates, the two connecting plates 5 move towards each other or in opposite directions.

[0035] Further, a first gear 61 is connected to the center of the bidirectional lead screw 6, and fixing rods 4 are symmetrically arranged on one side of the frame 1. A rotating rod 63 is rotatably arranged in the fixing rod 4. The lower end of the rotating rod 63 penetrates through the fixing rod 4 and is connected to a second gear 62. When the rotating rod 63 drives the second gear 62 to rotate, the first gear 61 is driven to rotate by the meshing of the second gear 62 with the first gear 61, thereby driving the bidirectional lead screw 6 to rotate.

[0036] Furthermore, a third gear 65 is connected to the top of the rotating rod 63. A double-headed gear 67 is rotatably arranged at the upper end of the frame 1. The third gear 65 meshes with the double-headed gear 67. A rotating ring is arranged at the center of the double-headed gear 67. When the food deliverer rotates the rotating ring, the double-headed gear 67 rotates. Through the meshing of the double-headed gear 67 with the third gear 65, the third gear 65 is driven to rotate the rotating rod 63, so that the food deliverer can brake the moving wheels 14 manually when standing.

[0037] In addition, a straight groove 15 is formed on one side of the frame 1. A lower pressing plate 9 is slidably connected in the straight groove 15. Symmetrical connecting rods 91 are arranged on the lower side of the lower pressing plate 9. A lower pressing block 92 is arranged on the lower side of the connecting rod 91. At the same time, an anti-slip plate 93 is arranged on the lower side of the lower pressing block 92. After the lower pressing plate 9 is pushed downward, the lower pressing plate 9 drives the connecting rod 91 to descend, so that the anti-slip plate 93 fits the ground, increasing the friction coefficient with the ground through the anti-slip plate 93 and improving the stability of the food truck.

[0038] To save operation steps, an adjusting lead screw 64 is connected to the upper end of the rotating rod 63. A pushing block 66 is threadedly connected to the adjusting lead screw 64. The pushing block 66 is limited by sliding in a limiting groove 41 formed on one side of the fixing rod 4. The pushing block 66 is located above the lower pressing plate 9. Therefore, when the rotating rod 63 rotates, the adjusting lead screw 64 is in threaded cooperation with the pushing block 66 and slides downward in the limiting groove 41 to push the lower pressing plate 9 downward, achieving two different braking effects with one action of the food deliverer. Among them, the upper end of the fixing rod 4 is of a hollow structure to facilitate the sliding of the pushing block 66.

[0039] To enable the lower pressing plate 9 to quickly reset when the pushing block 66 does not exert a thrust on the lower pressing plate 9, a fixing plate 7 is fixedly connected to the position of the frame 1 close to the middle. The connecting rod 91 penetrates through the fixing plate 7 and is slidably connected to the fixing plate 7. A spring 8 is arranged between the fixing plate 7 and the lower pressing plate 9. The spring 8 is compressed when the lower pressing plate 9 moves downward. Therefore, when the spring 8 is not stressed, the lower pressing plate 9 is urged to quickly reset.

[0040] A protective plate 2 is arranged on the outer side of the frame 1 to shield the above structure.

[0041] On the other hand, the present application also provides a food truck with a food truck braking mechanism, including: a top plate 11. The top plate 11 is located between a pair of frames 1. A sealing plate 12 is arranged on the lower side of the top plate 11. A pair of cabinet doors 13 are hinged at one sealing plate 12.

[0042] In summary, the working principle of a brake mechanism and a food truck according to an embodiment of the present utility model is as follows: Push the frame 1, and the device moves through the moving wheels 14. After reaching the designated location, the food deliverer rotates the double-headed gear 67. The double-headed gear 67 meshes with the third gear 65, causing the rotating rod 63 to drive the second gear 62 to rotate. Through the meshing of the second gear 62 and the first gear 61, the bidirectional lead screw 6 rotates, prompting the two connecting plates 5 to drive the brake blocks 51 to clamp the moving wheels 14 for braking. At the same time, while the rotating rod 63 rotates, the adjusting lead screw 64 is driven to rotate, causing the push block 66 to push the lower pressing plate 9 downward, making the anti-slip plate 93 fit with the ground.

[0043] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
