Description

Technical Field

[0001] This utility model relates to the field of catering transportation technology, and more specifically, to a catering trolley. Background Technology

[0002] Food carts play a vital role in the catering industry. They directly display the restaurant's dishes and beverages, allowing customers to see and smell the food they order, thus enhancing their anticipation and satisfaction while dining.

[0003] Food carts often require catering staff to transfer trays from the kitchen onto the cart's tray. However, with traditional methods, food carts often lack guardrails, which can lead to trays falling off the tray due to impacts from external factors while pushing the cart. While some carts are equipped with guardrails, placing the trays on the tray surface is not very convenient. Therefore, there is a need to improve and optimize the food cart. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a catering cart, which has the advantages of making it convenient for catering staff to place plates and preventing plates from falling off during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a catering cart, including a main support, an upper tray fixedly connected to the left side surface of the main support, a baffle movably connected inside the upper tray, a handle fixedly connected to one side surface of the baffle, a rotating shaft rotatably connected to the lower surface of the upper tray, a limiting block fixedly connected to the side of the rotating shaft, a first turntable fixedly connected to the lower surface of the rotating shaft, a limiting groove formed at the lower right end of the baffle, and the limiting block movably connected to the interior of the limiting groove.

[0006] As a preferred technical solution of this utility model: a fixing plate is fixedly connected to the right side surface of the main bracket, a threaded rod is threadedly connected to the inside of the fixing plate, a second turntable is fixedly connected to the upper surface of the threaded rod, a protective tube is fixedly connected to the lower surface of the fixing plate, the threaded rod is located inside the protective tube, a suction cup is fixedly connected to the lower surface of the threaded rod, and a limit ring is fixedly sleeved on the lower part of the threaded rod.

[0007] As a preferred technical solution of this utility model: the surface of the upper tray is provided with a horizontal groove, the side of the upper tray is provided with a notch, the baffle is movably connected to the inside of the horizontal groove, and the handle is movably connected to the inside of the notch.

[0008] As a preferred technical solution of this utility model: a first limiting block is fixedly connected to the lower surface of the upper tray, and a second limiting block is fixedly connected to the lower surface of the upper tray.

[0009] As a preferred technical solution of this utility model: an anti-detachment ring is fixedly connected to the lower right end of the baffle, and the anti-detachment ring is located above the limiting bracket.

[0010] As a preferred technical solution of this utility model: the front and rear parts of the fixing plate are provided with placement grooves, and a collection box is movably connected inside the placement grooves.

[0011] As a preferred technical solution of this utility model: a bottom tray is fixedly connected to the left side surface of the main support, a secondary support is fixedly connected to the left side surface of the bottom tray, the right side surface of the secondary support is fixedly connected to the left side surface of the upper tray, and casters are rotatably connected to the lower surfaces of the secondary support and the main support.

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

[0013] 1. This utility model allows the barrier to be raised to a certain height by moving the handle upwards. The limiting block has a certain magnetism, so that when the first turntable is rotated, the limiting block can be smoothly rotated 90 degrees, so that the limiting block is located below the limiting groove. At the same time, due to gravity, the barrier will be at a certain height. This device can make it convenient for catering staff to place plates when they need to do so, without the barrier obstructing the staff's operation. When the plates are being transported, the barrier can be raised to prevent the plates from falling to the ground due to collisions with external factors.

[0014] 2. This utility model rotates the second turntable, causing the threaded rod to rotate inside the fixed plate, thereby changing the height of the threaded rod. When the threaded rod descends, it can use the suction cup to contact the ground, thereby expelling the air and using atmospheric pressure to fix the position of the cart. However, when it is necessary to move the cart, simply rotate the second turntable in the opposite direction to place the suction cup at a certain height. This device can easily achieve the stability of the food cart, thereby ensuring the practicality of the food cart. Attached Figure Description

[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] like Figures 1 to 7 As shown, this utility model provides a catering cart, including a main support 1. An upper tray 2 is fixedly connected to the left side surface of the main support 1. A baffle 3 is movably connected inside the upper tray 2. A handle 4 is fixedly connected to one side surface of the baffle 3. A rotating shaft 5 is rotatably connected to the lower surface of the upper tray 2. A limiting block 6 is fixedly connected to the side of the rotating shaft 5. A first turntable 7 is fixedly connected to the lower surface of the rotating shaft 5. A limiting groove 8 is opened at the lower right end of the baffle 3. The limiting block 6 is movably connected to the limiting groove 8.

[0025] When the catering staff places the tray on the upper surface of the upper tray 2, they pull the handle 4 on one side upwards, causing the baffle 3 to move upwards from the inside of the upper tray 2 and disengage from the inside of the transverse groove 14. At this time, due to the limiting effect of the anti-detachment ring 18, the anti-detachment ring 18 can no longer be lifted upwards. At this time, the staff rotates the first turntable 7 with their other hand. Due to the limiting effect of the first limiting block 16, and the fact that the limiting block 6 has a certain magnetism, and since both the first limiting block 16 and the second limiting block 17 are iron blocks, the limiting block 6 is exactly located below the limiting groove 8. At this time, the handle 4 is released, so that the baffle 3 is at a certain height on the upper surface of the upper tray 2.

[0026] Among them, a fixing plate 9 is fixedly connected to the right side surface of the main bracket 1, a threaded rod 10 is threadedly connected inside the fixing plate 9, a second turntable 11 is fixedly connected to the upper surface of the threaded rod 10, a protective tube 12 is fixedly connected to the lower surface of the fixing plate 9, the threaded rod 10 is located inside the protective tube 12, a suction cup 13 is fixedly connected to the lower surface of the threaded rod 10, and a limit ring 24 is fixedly sleeved on the lower part of the threaded rod 10.

[0027] Before the staff needs to deliver the food a certain distance, the staff rotates the second turntable 11, which drives the threaded rod 10 to rotate. At the same time, because the threaded rod 10 is connected to the internal thread of the fixing plate 9, the suction cup 13 comes into contact with the ground. After the suction cup 13 comes into contact with the ground, the air inside the suction cup 13 is squeezed out, and atmospheric pressure is used to fix the suction cup 13, thereby fixing the position of the cart. However, the protective tube 12 is located outside the threaded rod 10. Since the thread on the surface of the threaded rod 10 is only a short section, the lower part of the protective tube 12 and the limiting ring 24 cooperate to prevent the threaded rod 10 from falling off the top of the fixing plate 9.

[0028] The upper tray 2 has a horizontal groove 14 on its surface and a notch 15 on its side. The baffle 3 is movably connected to the inside of the horizontal groove 14, and the handle 4 is movably connected to the inside of the notch 15.

[0029] The horizontal groove 14 provides space for the baffle 3, while the first limiting block 16 provides space for the handle 4, so that when the baffle 3 is lowered, the upper surfaces of the baffle 3 and the handle 4 are flush with the upper surface of the upper tray 2, thereby ensuring that catering staff can easily push the plates into the upper surface of the upper tray 2.

[0030] The lower surface of the upper tray 2 is fixedly connected to a first limiting block 16, and the lower surface of the upper tray 2 is fixedly connected to a second limiting block 17.

[0031] The rotation angle of the limiting support block 6 is limited by the first limiting block 16 and the second limiting block 17. At the same time, since the limiting support block 6 has a magnetic effect on the first limiting block 16 and the second limiting block 17 respectively, it can provide convenience for catering staff without having to consider whether the limiting support groove 8 and the limiting support block 6 are aligned.

[0032] Among them, the lower right end of the baffle 3 is fixedly connected with an anti-detachment ring 18, which is located above the limiting bracket 8.

[0033] The position of the stop 3 is limited by the anti-detachment ring 18, so that the stop 3 will not detach from its original position from the inside of the upper tray 2.

[0034] The fixing plate 9 has placement slots 19 at the front and rear, and a collection box 20 is movably connected inside the placement slots 19.

[0035] By embedding the collection box 20 inside the placement slot 19, the collection box 20 can be removed more easily, and the inside of the collection box 20 can be used to store garbage.

[0036] The main support 1 has a bottom tray 21 fixedly connected to its left side surface, a secondary support 22 fixedly connected to its left side surface, a secondary support 22 fixedly connected to its right side surface and a top tray 2's left side surface, and casters 23 rotatably connected to both the secondary support 22 and the lower surface of the main support 1.

[0037] Heavier items can be placed on the upper surface of the bottom tray 21. Since the center of gravity of the items placed on the upper surface of the bottom tray 21 is low, they can be used as spare trays. The secondary support 22 connects the upper tray 2 with the main support 1. At the same time, the presence of the casters 23 allows the food cart to be moved.

[0038] Working principle and usage process of this utility model:

[0039] When the catering staff places the tray on the upper surface of the upper tray 2, they pull the handle 4 on one side upwards, causing the baffle 3 to move upwards from the inside of the upper tray 2 and disengage from the inside of the transverse groove 14. At this time, due to the limiting effect of the anti-detachment ring 18, the anti-detachment ring 18 can no longer be lifted upwards. At this time, the staff rotates the first turntable 7 with their other hand. Due to the limiting effect of the first limiting block 16, and the fact that the limiting block 6 has a certain magnetism, and since both the first limiting block 16 and the second limiting block 17 are iron blocks, the limiting block 6 is exactly located below the limiting groove 8. At this time, the handle 4 is released, so that the baffle 3 is at a certain height on the upper surface of the upper tray 2.

[0040] Before the staff needs to deliver the food a certain distance, the staff rotates the second turntable 11, which drives the threaded rod 10 to rotate. At the same time, because the threaded rod 10 is connected to the internal thread of the fixing plate 9, the suction cup 13 comes into contact with the ground. After the suction cup 13 comes into contact with the ground, the air inside the suction cup 13 is squeezed out, and atmospheric pressure is used to fix the suction cup 13, thereby fixing the position of the cart. However, the protective tube 12 is located outside the threaded rod 10. Since the thread on the surface of the threaded rod 10 is only a short section, the lower part of the protective tube 12 and the limiting ring 24 cooperate to prevent the threaded rod 10 from falling off the top of the fixing plate 9.

[0041] The horizontal groove 14 provides space for the baffle 3, while the first limiting block 16 provides space for the handle 4, so that when the baffle 3 is lowered, the upper surfaces of the baffle 3 and the handle 4 are flush with the upper surface of the upper tray 2, thereby ensuring that catering staff can easily push the plates into the upper surface of the upper tray 2.

[0042] The rotation angle of the limiting support block 6 is limited by the first limiting block 16 and the second limiting block 17. At the same time, since the limiting support block 6 has a magnetic effect on the first limiting block 16 and the second limiting block 17 respectively, it can provide convenience for catering staff without having to consider whether the limiting support groove 8 and the limiting support block 6 are aligned.

[0043] The position of the stop 3 is limited by the anti-detachment ring 18, so that the stop 3 will not detach from its original position from the inside of the upper tray 2.

[0044] By embedding the collection box 20 inside the placement slot 19, the collection box 20 can be removed more easily, and the inside of the collection box 20 can be used to store garbage.

[0045] Heavier items can be placed on the upper surface of the bottom tray 21. Since the center of gravity of the items placed on the upper surface of the bottom tray 21 is low, they can be used as spare trays. The secondary support 22 connects the upper tray 2 with the main support 1. At the same time, the presence of the casters 23 allows the food cart to be moved.
