Description

Technical Field

[0001] The utility model belongs to the technical field of catering, and relates to catering utensils, in particular to a dining car. Background Art

[0002] A dining cart is a metal trolley that can transport dishes. In the prior art, there are problems such as inconvenient positioning of dining carts after they are moved and lack of storage space. In addition, due to insufficient countertop space, there is not enough space to place dining utensils and tableware, which often requires hand-held tableware when serving dishes. This is not only inconvenient for serving dishes, but also easy to cause burns. For this reason, people have conducted long-term explorations and proposed various solutions.

[0003] For example, a Chinese patent document discloses a mobile serving table [application number: CN201921327882.7], which includes a serving table body, a handle disposed on the side of the serving table body, a plurality of movable wheels disposed on the bottom of the serving table body, a connecting mechanism for connecting the movable wheels to the serving table body, and a brake mechanism. The utility model is convenient to use. When the serving table needs to be moved, the handle can be directly pushed by hand, and the brake pedal can be stepped on to fix the position after moving to the designated position.

[0004] Although the above solution has a good positioning effect, the countertop space is still small during use, which makes it inconvenient for children to serve dishes or rice by themselves. Summary of the invention

[0005] The purpose of the utility model is to provide a dining car in view of the above problems, and solve the technical problems of the prior art such as small table space.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the dining cart comprises a box body and a plurality of wheels arranged at the bottom of the box body, a push handle is provided at one end of the box body, a hot water tank is provided at the top of the box body, and a lunch box rack is provided above the hot water tank. It is characterized in that dining boards are provided on both sides of the box body, and the dining boards are connected to the box body by at least one hinge, and the hinge is provided with a hinge locking assembly that can prevent the dining board from continuing to rotate when the dining board rotates around the hinge to be parallel to the box body table top.

[0007] Since there are dining boards on both sides of the box that can rotate around hinges, they can be stored on both sides when not in use. When the dining boards are rotated to a position parallel to the table top of the box, the table space is increased, making the process of serving dishes more convenient, so that children can put their bowls on the dining boards and serve dishes or rice by themselves, thereby cultivating independent hands-on ability.

[0008] In the dining cart, the hinge includes a first leaf body and a second leaf body in a strip shape and a U-shaped cross section. The first leaf body is fixed to the side of the box body, and the second leaf body is fixed to the back of the dining board. The upper end of the first leaf body is connected to the upper end of the second leaf body through a hinge structure. A hinge locking assembly is provided between the first leaf body and the second leaf body to prevent the dining board from continuing to rotate when the dining board rotates around the hinge structure to be parallel to the table surface of the box body.

[0009] In the dining car, the hinge locking assembly comprises two support rods respectively located on both sides of the first leaf body and the second leaf body, the lower ends of the two support rods are respectively fixed to the ends of the first pivot shafts penetrating the first leaf body, the first pivot shaft is far away from the hinge structure, the upper ends of the two support rods are fixed to the slide rod, the slide rod is penetrating in the slide groove of the second leaf body, the slide groove is distributed along the length direction of the second leaf body, the second leaf body is pivoted with a locking block located below the slide groove, an elastic locking structure is provided between the locking block and the second leaf body to enable the upper end of the locking block to abut against the back of the second leaf body, and an unlocking and retreating section is provided at the inner end of the slide groove. Supporting by two support rods can improve the stability of support, make the acceptance more uniform, prevent eccentric wear, and improve durability; one end of the support rod is pivoted with the first leaf body, and the other end is slidably connected with the second leaf body and locked by the elastic locking structure, so as to facilitate folding and unfolding.

[0010] In the dining car, the elastic locking structure includes a torsion spring, the locking block is strip-shaped and the middle part is connected to the second leaf body through the second pivot shaft, the torsion spring is passed through the second pivot shaft and one end abuts against the second leaf body, and the other end abuts against the locking block. The torsion spring can automatically lift the locking block, so that when the dining plate needs to be opened, only the dining plate needs to be lifted to automatically locate the locking position, and the use process is convenient and quick. When disassembly is required, the slide bar is first allowed to enter the unlocking retreat section, and then the outer end of the lock block is pressed to unlock the slide bar.

[0011] In the dining cart, the second blade is provided with a first pivot shaft clearance groove which enables the second blade to be parallel to each other when the outer end of the second blade rotates downward around the hinge structure to be perpendicular to the bottom surface. The first pivot shaft clearance groove is provided so that after the dining board is folded, its outer surface is perpendicular to the bottom surface, thereby reducing the volume after folding; that is, the two dining boards can be parallel to each other after folding.

[0012] In the dining car, the hinge structure includes a hinge rod, the width of the second blade is smaller than the width of the first blade, and the inner end of the second blade is hinged to the upper end of the first blade via the hinge rod. The hinge rod hinge arrangement facilitates the rotation between the open and close blades of the dining board.

[0013] In the dining car, the first blade is fixed in the retreat groove on the side of the box body. By providing the retreat groove, the overall structure can be made more compact, and the dining board can be close to the box body when it is not unfolded.

[0014] In the above-mentioned dining car, a first storage basket is provided at one end of the box body and is located below the push handle. The first storage basket is connected to the slot of the box body through an L-shaped hook. The first storage basket can provide additional storage space and is arranged below the push handle for easy access. Moreover, due to the plug-in detachable structure, the first storage basket can be removed when not in use, thereby reducing the storage volume of the dining car and facilitating the cleaning of the first storage basket.

[0028] More specifically, if Figure 2-3As shown, the hinge 15 includes a first leaf body 151 and a second leaf body 152 which are strip-shaped and have a U-shaped cross section. The first leaf body 151 is fixed to the side of the box body 1, and the second leaf body 152 is fixed to the back of the dining board 14. The upper end of the first leaf body 151 is connected to the inner end of the second leaf body 152 through a hinge structure 154. A hinge locking assembly 153 is provided between the first leaf body 151 and the second leaf body 152 to prevent the dining board 14 from continuing to rotate when the dining board 14 rotates around the hinge structure 154 to be parallel to the table surface of the box body 1. The hinge locking assembly 153 includes two support rods 1531 respectively located on both sides of the first leaf body 151 and the second leaf body 152. The two support rods 1531 The lower ends are respectively fixed to the ends of the first pivot shaft 1511 penetrating the first leaf body 151, and the first pivot shaft 1511 is far away from the hinge structure 154. The upper ends of the two support rods 1531 are fixed to the sliding rod 1532, and the sliding rod 1532 is penetrated in the sliding groove 1521 of the second leaf body 152. The sliding groove 1521 is distributed along the length direction of the second leaf body 152.

[0029] In this embodiment, Figure 3 As shown, the elastic locking structure 1551 includes a torsion spring 1551A, the locking block 155 is strip-shaped and the middle part is connected to the second leaf body 152 through the second pivot shaft 1522, the torsion spring 1551A is passed through the second pivot shaft 1522 and one end abuts against the second leaf body 152, and the other end abuts against the locking block 155.

[0030] In order to reduce the storage volume and make the structure more compact, the second leaf body 152 is provided with a first pivot axis yielding groove 1523 which enables the second leaf body 152 and the first leaf body 151 to be parallel to each other when the outer end of the second leaf body 152 rotates downward around the hinge structure 154 to be perpendicular to the bottom surface. The hinge structure 154 includes a hinge rod 1541. The width of the second leaf body 152 is smaller than the width of the first leaf body 151. The inner end of the second leaf body 152 is hinged to the upper end of the first leaf body 151 through the hinge rod 1541. The first leaf body 151 is fixed in the yielding groove 16 at the side of the box body 1. The inner end of the second leaf body 152 exceeds the inner end of the dining plate 14 and is located outside. The dining plate 14 is close to the inner end of the second leaf body 152, so that the part of the inner end of the second leaf body 152 that exceeds the inner end of the second leaf body 152 can enter the yielding groove 16.

[0031] In order to increase the external storage space, such as Figure 1 As shown, a first storage basket 1A is provided at one end of the box body 1 and is located below the push handle 11 . The first storage basket 1A is connected to a slot 1A2 of the box body 1 via an L-shaped hook 1A1 .

[0032] In this embodiment, a flat bar 1A3 is provided at one end of the box body 1, and both ends of the flat bar 1A3 are respectively welded to the box body 1, forming a slot 1A2 between the flat bar 1A3 and the box body 1, and the first storage basket 1 is connected to the L-shaped hook 1A1 as a whole.

[0033] like Figure 1 , 5 As shown in FIGS. 6 and 7 , an inverted U-shaped lifting frame 17 is provided at the other end of the box body 1. The lifting frame 17 is inserted into the box body 1, and bayonet holes 171 are respectively provided at both ends of the lifting frame 17. A transverse clamping tube 18 capable of cooperating with the bayonet holes 171 is provided in the box body 1. A second storage basket 1B is provided between the lifting frame 17 and the box body 1, and a hanging ear 1B1 is provided on the second storage basket 1B. The hanging ear 1B1 is provided with a hanging hole 1B2 capable of being passed through by the lifting frame 17.

[0034] The working principle of this embodiment is as follows: when the dining plate 14 needs to be unfolded, the outer end of the dining plate 14 is lifted, the outer end of the second leaf body 152 rotates around the hinge rod 1541, and the slide bar 1532 moves from the outer end to the inner end of the slide groove 1521. When the slide bar 1532 encounters the locking block 155, the slide bar 1532 passes through the upper surface of the locking block 155. The upper end of the locking block 155 rotates downward around the second pivot axis 1522 under the action of the torsion spring, and the slide bar 1532 moves out of the range of the locking block 155 and enters the slide groove 1521. When the inner end of the dining board 14 is unlocked and the retreat section 1521A is unlocked, the locking block 155 is automatically reset. At this time, the angle between the outer surface of the dining board 14 and the table top of the box body 1 is less than 180 degrees, and the angle between the second leaf body 152 and the first leaf body 151 is greater than 90 degrees. Then the force for lifting the dining board 14 is released, and the sliding rod 1532 moves toward the outer end of the slide groove 1521 to exit the unlocking and retreat section 1521A and abut against the lower surface of the locking block 155 and the bottom surface of the slide groove 1521, thereby completing the unfolding.

[0035] When it is necessary to fold the dining board 14, lift the outer end of the dining board 14, and after the slide bar 1532 enters the unlocking retreat section 1521A, press the lower end of the locking block 155 to rotate its upper end to the bottom of the slide groove 1521. At this time, release the force to lift the dining board 14 or press the outer end of the dining board 14 downward, and the slide bar 1532 moves to the outer end of the slide groove 1521, so that the outer surface of the dining board 14 is perpendicular to the bottom surface, and the storage is completed.

[0036] When the lifting frame 17 needs to hang the second storage basket 1B, the lifting frame 17 is pulled up and the bayonet 171 is engaged with the transverse clamping tube 18, and the second storage basket 1B passes through the hanging hole 1B2 and is hung on the box body 1 through the hanging ear 1B1. At this time, the second storage basket 1B exerts a transverse force on the lifting frame 17, and when the lifting frame 17 is in a force-bearing state, the bayonet 171 clamps the transverse clamping tube 18 and does not separate from the transverse clamping tube 18, thereby maintaining the lifting state.

[0037] When the second storage basket 1B does not need to be hung, the second storage basket 1B is removed, and the lateral force on the lifting frame 17 disappears, so that the clamping port 171 can be separated from the lateral clamping tube 18, so that the lifting frame 17 descends.
