[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 4 In an embodiment of the utility model, a food delivery and dining cart that can prevent tipping over comprises a plurality of upper and lower frames 1, two adjacent frames 1 are connected by a column 4, a fixed plate 2 is welded at the center of the topmost frame 1, a sliding plate 3 is axially slidably connected to the inner side of the other plurality of frames 1, and one end of the other plurality of frames 1 is an open structure; the sliding plate 3 slides with the corresponding frame 1 through a sliding limit mechanism, and the sliding limit mechanism is used to limit the maximum sliding distance of the sliding plate 3; a blocking mechanism is arranged inside a column 4 close to the opening of the frame 1, the blocking mechanism in the reset state is used to limit the sliding plate 3 to the initial position, and the blocking mechanism in the unlocked state is used to release the blocking of the sliding plate 3.

[0023] In this embodiment: when delivering food, the food placed on the fixed plate 2 can be directly taken. When the food on the sliding plate 3 needs to be taken, the blocking mechanism is first pulled up to contact the restriction of the blocking mechanism on the sliding limit mechanism, and then the sliding plate 3 can be pulled outward. After the sliding plate 3 is pulled out, the food placed on the sliding plate 3 can be directly taken. In this way, the problem of collision between food on the lower layer can be avoided, thereby preventing the food from tipping over.

[0024] Please refer to Figure 2 , Figure 3 and Figure 4 The sliding limit mechanism includes a slide groove 8 opened on the inner side of the two longitudinal plates of the sliding disk 3, and the inner wall of the slide groove 8 is axially slidably connected with a slider 10, and the two sliders 10 are fixedly connected to the two sides of the sliding disk 3; the top of the end of the slider 10 is provided with a protrusion 12 protruding upward, and the top of the inner wall of the slider 10 is provided with a connecting groove 13 for the protrusion 12 to slide, and the front and rear ports of the connecting groove 13 are both closed structures.

[0025] In this embodiment: when the blocking mechanism releases the blocking of the sliding limit mechanism, the sliding plate 3 is pulled outward, and the sliding plate 3 drives the slider 10 to move in the sliding groove 8, and the slider 10 simultaneously drives the protrusion 12 to move in the connecting groove 13, until the protrusion 12 contacts the inner side of the other closed end of the connecting groove 13, at which time the sliding plate 3 cannot continue to slide, thereby avoiding the problem of direct separation of the sliding plate 3 and the frame 1 due to pulling.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The blocking mechanism includes a limit groove 14 vertically opened inside the column 4, a spring 15 is installed at the top of the inner wall of the limit groove 14, and the bottom end of the spring 15 is connected to a baffle 16 slidably connected to the inner wall of the limit groove 14, and the baffle 16 in the reset state is used to block the slider 10, a slot 9 is opened at one end of the column 4, the slot 9 is connected to the inner cavity of the limit groove 14, and the inner wall of the slot 9 is slidably connected to a lifting rod 6 that penetrates to the outside of the column 4, and the other end of the lifting rod 6 is fixedly connected to the baffle 16.

[0027] In this embodiment: by pulling the lifting rod 6 upward, the lifting rod 6 moves upward along the slot 9, and the baffle 16 moves upward along the limiting slot 14. At this time, the spring 15 is compressed. When the bottom end of the baffle 16 moves to the top of the slider 10, the sliding plate 3 can be pulled outward. After taking the meal, the sliding plate 3 is pushed to reset until the slider 10 no longer blocks the bottom of the baffle 16. At this time, the spring 15 is reset, driving the baffle 16 to block the slider 10 again, so as to avoid the self-sliding problem of the slider 10 when the dining cart moves.

[0028] Please refer to Figure 2 and Figure 4 The other end of the column 4 away from the notch 9 is fixedly connected to a sealing plate 7 for closing the opening of the limiting groove 14.

[0029] In this embodiment, the sealing plate 7 seals the opening of the limiting groove 14 to prevent the baffle 16 from being separated from the limiting groove 14 .

[0030] Please refer to Figure 1 A handle 5 is provided on the edge of the sliding plate 3 near the opening position of the frame 1, and a push handle 11 is installed on the outer side of the column 4 away from the blocking mechanism and the sliding limit mechanism.

[0031] In this embodiment, the dining cart can be pushed to move by the push handle 11, and the sliding plate 3 can be conveniently pulled to move by the handle 5.
