Description

Technical Field

[0001] This utility model relates to the field of food delivery vehicle technology, specifically a food delivery vehicle used in prison wards. Background Technology

[0002] Food delivery carts used in prison wards are essential tools for ensuring the food supply to inmates. They typically have large-capacity containers to accommodate bulk food transport. The containers are mostly made of stainless steel, which is not only sturdy and durable but also easy to clean and disinfect, meeting hygiene standards. The carts feature layered or compartmentalized designs to clearly separate different types of food and prevent mixing. The wheels are made of quiet and wear-resistant rubber to minimize noise disturbance within the prison area. The carts may also be equipped with heating or insulation devices to ensure that the food remains at a suitable temperature when delivered to inmates, guaranteeing they receive hot and palatable meals.

[0003] Currently, food delivery carts are susceptible to damage in the event of a collision, compromising safety. Furthermore, the seats are typically secured with multiple bolts and nuts, making adjustments difficult. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a food delivery vehicle for prison wards, which solves the problem that collision impacts can cause significant damage to the food delivery vehicle, and also solves the problem that the seat is inconvenient to adjust.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the design of a rotating handlebar and seat, enables the food delivery vehicle to move forward and backward without the need to turn around during movement. This can effectively improve delivery efficiency, especially in narrow spaces. Furthermore, the rotating design of the seat and bracket allows for flexible adjustment of the seat, making it easy to adjust the seating posture and improving the driving comfort of the food delivery vehicle.

[0014] 2. This utility model utilizes the design of a buffer plate. When the buffer plate is impacted, it can deflect, thereby deflecting the hinge rod and pushing the slider upward to compress the first spring. Under the elastic action of the first spring, the impact force generated by the collision can be buffered, reducing the damage to the catering cart and improving operational safety. Furthermore, under the action of the friction block, the rebound force of the spring can be unloaded, preventing secondary damage caused by the rebound of the buffer plate.

[0023] Please see Figure 1, Figure 3 The buffer mechanism 8 includes a buffer plate 81. Buffer plates 81 are hinged to both the left and right ends of the frame 1. A hinge rod 82 is hinged to the outer side of the buffer plate 81. A slider 83 is fixedly connected to the other end of the hinge rod 82. The slider 83 is slidably connected to the frame 1. A first spring 84 is provided inside the frame 1. One end of the first spring 84 is fixedly connected to the frame 1, and the other end of the first spring 84 is fixedly connected to the slider 83. By designing the first spring 84, the force of the first spring 84 can act on the slider 83. A guide block 85 is fixedly connected to the outer side of the slider 83. The guide block 85 is slidably connected to the frame 1. A guide groove 86 is provided inside the frame 1. The guide block 85 is slidably connected inside the guide groove 86. By designing the guide groove 86, the guide block 85 can slide inside the guide groove 86. A friction block 87 is fixedly connected inside the frame 1. By designing the buffer mechanism 8, the impact force of the food delivery vehicle collision can be buffered.

[0024] Please see Figure 1 , Figure 4 , Figure 5 The adjusting mechanism 9 includes slots 91. Slots 91 are provided inside the support 10. A rod 92 is slidably connected inside each slot 91. Multiple slots 91 are evenly distributed in a semi-circular pattern inside the support 10. By designing multiple slots 91, the rod 92 can be inserted into slots 91 at different positions. The rod 92 is slidably connected to the hinge seat 11. A fixing seat 93 is slidably sleeved on the outer side of the rod 92. The fixing seat 93 is fixedly connected to the hinge seat 11. A connecting block 94 is fixedly connected to the upper end of the rod 92. The connecting block 94 slidably connects to the fixing seat 93. The seat 92 is connected to a fixed base 93. A second spring 95 is installed inside the fixed base 93. One end of the second spring 95 is fixedly connected to the connecting block 94, and the other end of the second spring 95 is fixedly connected to the fixed base 93. The second spring 95 is designed so that its force can act on the connecting block 94. A magnetic block 96 is fixedly connected to the lower end of the insertion rod 92. The magnetic block 96 is slidably connected to the fixed base 93. A magnet 97 is fixedly connected inside the fixed base 93. A push block 98 is fixedly connected to the outer side of the insertion rod 92. The adjustment mechanism 9 is designed to facilitate flexible adjustment of the seat 12's position.

[0025] The specific implementation process of this utility model is as follows: When in use, the rotating design of the handlebar 7 and the seat 12 enables the food delivery vehicle to move forward and backward without having to turn around during movement, which can effectively improve food delivery efficiency, especially in narrow spaces. When the angle of the seat 12 needs to be adjusted, push the push block 98 directly. The push block 98 drives the insertion rod 92 to move horizontally. The insertion rod 92 drives the connecting block 94 to move horizontally. The connecting block 94 will compress the second spring 95. At the same time, the insertion rod 92 drives the magnetic block 96 to move horizontally. When the magnetic block 96 is attracted to the magnet 97, the insertion rod 92 will slide out from the slot 91. Then rotate the seat 12. The seat 12 can drive the hinge seat 11 to rotate along the bracket 10. After the adjustment is completed, push the push block 98 in the opposite direction to reset the insertion rod 92. At the same time, the magnetic block 96 separates from the magnet 97. Under the elastic action of the second spring 95, the insertion rod 92 can be pushed into the slot 91 in another position, so that the seat 12 can be flexibly tilted and adjusted. This allows for convenient adjustment of the sitting posture and improves the driving comfort of the food delivery vehicle.

[0026] When the buffer plate 81 is impacted, it can deflect, which in turn causes the hinge rod 82 to deflect. This pushes the slider 83 upward to compress the first spring 84. Under the elastic action of the first spring 84, the impact force generated by the collision can be buffered, reducing the damage to the dining car and improving operational safety. When the slider 83 moves upward, it will contact the friction block 87. Subsequently, under the elastic action of the first spring 84, the slider 83 will be pushed back to its original position. Under the action of the friction block 87, the movement of the slider 83 can be provided with certain resistance, which can unload the rebound force of the spring and avoid secondary damage caused by the rebound of the buffer plate 81.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
