Abstract
Description
Technical Field
[0001] This utility model relates to the field of food truck technology, specifically a towable food truck. Background Technology
[0002] A towed food truck is a catering equipment that is moved by a vehicle. It is usually converted from a trailer and has no power system of its own. It needs to be towed by a vehicle in front to flexibly move its business location.
[0003] When food trucks are moved to different locations, they are usually towed by other vehicles. However, when towing a food truck, the driver's limited field of vision makes it difficult to accurately adjust the relative position of the towing parts. This requires constant adjustments to the position of the vehicle or food truck for the towing to be completed. This method is very time-consuming and labor-intensive, which affects the progress of the towing. Therefore, we have proposed a towing-type food truck. Utility Model Content

[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 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.
[0024] Please see Figure 1-6 As shown, a towable food cart includes a tow frame 1. Fixing strips 13 are fixedly connected to both the left and right sides of the tow frame 1. Limiting pins are threaded into the internal parts of the fixing strips 13. A limiting hole is provided on the surface of a rotating plate 4 to cooperate with the limiting pin. The fixing strips 13 allow the rotating plate 4 to be retracted to the surface of the tow frame 1, where the limiting pin can be used to limit and fix the rotating plate 4. A food cart body 2 is rotatably connected to the rear side of the tow frame 1. A telescopic frame 3 is slidably connected inside the tow frame 1. Limiting mechanisms 8 are provided on both the left and right sides of the telescopic frame 3. Square sliding grooves 11 that cooperate with the limiting mechanisms 8 are provided on both the left and right sides of the tow frame 1. A tiger-head hook 5 is bolted to the front side of the telescopic frame 3. The left and right sides of the tow frame 1... Limiting plates 6 are fixedly connected to both sides. A rotating plate 4 is hinged to the bottom of the traction frame 1. A telescopic plate 7 is slidably connected inside the rotating plate 4. Slider blocks 14 are fixedly connected to both the left and right sides of the telescopic plate 7. A sliding groove is provided on the inner wall of the rotating plate 4 to cooperate with the slider 14. The slider 14 can guide the sliding direction of the telescopic plate 7, ensuring that the telescopic plate 7 runs smoothly during the extension and retraction process. It can also limit the extension and retraction distance of the telescopic plate 7 to prevent it from sliding out of the rotating plate 4. A transmission mechanism 15 is provided inside the telescopic plate 7. A handwheel 9 is provided on the surface of the rotating plate 4. A pin 10 is slidably connected inside the handwheel 9. Several limiting holes are provided on the right side of the rotating plate 4 to cooperate with the pin 10.
[0025] The limiting mechanism 8 includes a fixed block 81, which is fixedly connected to the surface of the telescopic frame 3. A movable rod 82 is slidably connected inside the fixed block 81. A fixed plate 84 is fixedly connected to the surface of the movable rod 82. A spring 83 is fixedly connected to the top of the fixed plate 84. The other end of the spring 83 is fixedly connected to the inner wall of the fixed block 81. The spring 83 is sleeved on the surface of the movable rod 82. Through the setting of the limiting mechanism 8, when the telescopic frame 3 needs to extend for docking, the movable rod 82 can be pulled upwards. Handles 12 are fixedly connected to the top of the movable rods 82 on both sides. The surface of the handles 12 is provided with anti-slip pads. The handle 12 is designed so that the operator can manually pull the movable rod 82 to disengage it from the inside of the limiting plate 6, thereby facilitating the adjustment of the telescopic frame 3. The anti-slip pad on its surface increases the friction during operation and prevents slippage. At the same time, the fixing plate 84 compresses the spring 83, causing the bottom end of the movable rod 82 to disengage from the limiting hole of the limiting plate 6, thereby removing the limitation on the telescopic frame 3. After the telescopic frame 3 is adjusted to the appropriate position, the elastic force of the spring 83 allows the movable rod 82 to be reinserted into the limiting hole in the limiting plate 6, thus facilitating the fixation of the telescopic frame 3.
[0026] The transmission mechanism 15 includes a transmission shaft 151, which is rotatably connected to the rotating plate 4. A handwheel 9 is fixedly connected to one end of the transmission shaft 151, and a first bevel gear 152 is fixedly connected to the other end. A fixed plate 16 is fixedly connected to the inner wall of the rotating plate 4, and a fixed sleeve 154 is fixedly connected to the surface of the fixed plate 16. A threaded rod 155 is rotatably connected inside the fixed sleeve 154, and a second bevel gear 153 is fixedly sleeved on the surface of the threaded rod 155. The first bevel gear 152 and the second bevel gear 153 mesh with each other. The top of the threaded rod 155 is rotatably connected to the top of the inner wall of the rotating plate 4. The threaded rod 155 is threaded through the top of the telescopic plate 7 and connected to its internal thread. With the transmission mechanism 15, when the docking height is insufficient, the transmission shaft 151 can be rotated, which will drive the first bevel gear 152 to rotate and simultaneously drive the second bevel gear 153 to rotate, causing the threaded rod 155 to rotate. This will drive the telescopic plate 7 to move, thereby adjusting the height of the docking point for traction docking.
[0027] Working principle: When the worker connects and tows the food cart body 2, first adjust the angle of the towing frame 1 according to the position of the towing vehicle, aligning it with the docking position of the towing vehicle. During the adjustment process, if there is still a certain distance between the towing vehicle and the towing frame 1, the handle 12 can be pulled without moving the towing vehicle. This will cause the handle 12 to move the movable rod 82 upward, and cause the fixed plate 84 to compress the spring 83, causing the other end of the movable rod 82 to disengage from the inside of the limiting plate 6, thereby releasing the limitation on the telescopic frame 3. Then, the telescopic frame 3 is pulled out so that it can reach the connection position with the towing vehicle. Next, the movable rod 82 is aligned with the limiting hole in the limiting plate 6, and the handle 12 is released. Then, the spring... The elastic force of the spring 83 causes the movable rod 82 to re-insert into the limiting hole, thereby re-fixing the telescopic frame 3. If there is a certain height difference between the tractor and the tractor frame 1, the fixing strip 13 can be flipped so that the limiting pin on the inner side of the fixing strip 13 disengages from the hole on the surface of the rotating plate 4, thereby canceling the limitation on the rotating plate 4. Then the rotating plate 4 can be flipped so that it is perpendicular to the ground. Then the handwheel 9 is rotated, and the first bevel gear 152 is rotated through the transmission shaft 151, which in turn drives the second bevel gear 153 to rotate and the threaded rod 155 to rotate, thereby causing the telescopic plate 7 to move up and down, thereby supporting the tractor frame 1 and allowing the tractor frame 1 to better dock with the tractor.
