Description

Technical Field

[0001] This utility model belongs to the field of tableware technology, specifically relating to a portable folding frame and folding device. Background Technology

[0002] As people's living standards continue to improve, picnics and camping have enriched their leisure time, making dining tables, chairs, and cooking counters essential items for outings. To minimize space usage, portability of these essentials is crucial. (Publication number: CN) Utility model patent 211747835U discloses a foldable smart dining table. It features a first fixed base at the bottom of a first support column, with a first universal wheel at the bottom of the first fixed base. A second fixed base at the bottom of a second support column, with a second universal wheel at the bottom of the second fixed base, is also present. A sleeve is provided on one side of the first support column, and a sleeve rod on one side of the second support column. A locking device is provided at the bottom of the outer surface of the sleeve, and an electric telescopic rod is provided at the top of the outer surface of the sleeve. A rotating shaft is provided at the top of the electric telescopic rod. A first tabletop is located on one side of the rotating shaft, and a second tabletop on the other side. A collar rod is provided at the bottom of the first tabletop, and a collar tube is provided at the bottom of the second tabletop. A first rotating seat is located at the bottom of the first tabletop and on the side of the collar rod, and a second rotating seat is located at the bottom of the second tabletop and on the side of the collar tube. The first support column is rotatably connected to the bottom of the first tabletop via the first rotating seat, and the second support column is rotatably connected to the bottom of the second tabletop via the second rotating seat. When folding is needed, the electric telescopic rod extends upward, causing the rotation axis to move upward. Due to gravity, the first and second tabletops can move closer together on one side, allowing the sleeve rod to extend into the sleeve tube and the collar rod to extend into the collar tube. Although this folding table can reduce the space occupied to some extent, it still occupies a considerable amount of space when folded due to the support of the sleeve and collar tube.

[0003] The utility model patent with publication number CN218431029U discloses a foldable dining table structure for RVs. It has a flip-up tabletop installed on the front side of the mounting plate. The tabletop has a main board with a pull-out sliding plate. Although this folding table achieves the folding of the tabletop, the mounting plate needs to be attached to vertical installation objects such as the side wall of the vehicle and cannot be used independently. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable folding frame and folding device that can be used independently or completely folded.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a portable folding frame is designed, including a first support and a second support arranged opposite to each other. The feature is that it also includes a bending arm and a bending plate. Both the bending arm and the bending plate can be folded in the middle. The bending plate can be placed on the upper end of the bending arm. One end of the bending arm is vertically hinged to the first support and the other end is vertically hinged to the second support. One end of the bending plate is horizontally hinged to the first support and the other end is horizontally hinged to the second support.

[0006] Preferably, there are two bending arms, and the two bending arms can be bent in opposite directions.

[0007] Preferably, the bending arm is formed by two arms hinged together, and the bending plate is formed by two plates hinged together.

[0008] Preferably, the first bracket and the second bracket are each provided with two legs, and a bending arm and a bending plate are installed on the legs.

[0009] Preferably, the outrigger is equipped with casters, and the casters are fitted with brakes.

[0010] Preferably, the first support and the second support are each provided with two or more horizontal supports, one end of which is connected to one leg and the other end is connected to another leg, and the two or more horizontal supports are arranged sequentially from top to bottom.

[0011] This utility model also provides a portable folding device, including a folding frame, which is the aforementioned portable folding frame, and a table panel. A groove is provided on the bottom wall of the table panel, and the top ends of the first support and the second support are inserted into the groove.

[0012] Preferably, the first bracket is provided with two opposing support arms, and the table panel is hinged to the support arms.

[0013] Preferably, the tabletop is provided with a pin, and the tabletop is connected to the second bracket by the pin.

[0014] Preferably, a stove head is installed on the countertop.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Because one end of the bending arm is vertically hinged to the first support and the other end is vertically hinged to the second support, and one end of the bending plate is horizontally hinged to the first support and the other end is horizontally hinged to the second support, and both the bending arm and the bending plate can be folded in the middle, the bending plate can be placed on the upper end of the bending arm, so that the fold line of the bending arm and the bending plate form a cross shape, which can not only achieve complete folding, but also stably support the first and second supports, and also allow the bending plate to be used as a storage platform in the open state, thus improving the practicality of the folding frame.

[0016] 2. Designing two bending arms can further enhance the stability of the first and second supports, and the two bending arms can bend in opposite directions, so that the bending arms bend inward and do not increase the length of the folded frame.

[0017] 3. Since the bending arm is formed by two arms hinged together and the bending plate is formed by two plates hinged together, the structure of the bending arm and the bending plate is simplified, which helps to improve its cost performance.

[0018] 4. Since the first and second supports are each equipped with two legs, the bending arm and bending plate are installed on the legs, which facilitates the support of the folding frame, simplifies the structure of the folding frame, reduces material usage, and lowers costs.

[0019] 5. Because the outriggers are equipped with casters, the folding frame can be pushed and moved easily; the casters are also equipped with brakes, which make it easy to fix the folding frame stably after it is moved to a suitable position.

[0020] 6. Since the first and second supports are also equipped with two or more horizontal braces, one end of the horizontal brace is connected to one leg and the other end is connected to another leg. The two or more horizontal braces are arranged from top to bottom, so that the horizontal braces and the legs form a support, thereby simplifying the structure of the support and reducing the amount of materials consumed.

[0021] 7. Because the bottom wall of the table panel has a groove, the tops of the first and second supports are inserted into the groove, so that the groove has a circumferential limiting effect on the top of the folding frame, thereby enhancing the stability of the folding device.

[0022] 8. Since the first bracket has two opposing support arms, the table panel is hinged to the support arms, which allows the table panel to be folded to one side of the folding frame. This facilitates the unfolding installation of the folding device and reduces the size of the folding device.

[0023] 9. Because the tabletop is equipped with a pin, the tabletop can be connected to the second bracket through the pin, which can achieve relative fixation between the tabletop and the folding frame and facilitate operation.

[0024] 10. Since the countertop is equipped with a stove, the folding rack can be used as a stove rack, which can meet the cooking needs during outdoor cooking and expand its range of uses. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] The height direction corresponding to the present invention in use is defined as vertical, and the left and right direction, i.e. the width direction, is defined as horizontal.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model includes a first support and a second support 2 arranged opposite to each other. A bending arm 6 and a bending plate 5 are connected between the first support 1 and the second support 2. The bending plate 5 can be placed on the upper end of the bending arm 6. Specifically, the bending arm 6 is formed by two equal-sized arms 10 hinged together, so that the bending arm 6 can be folded in the middle. One arm 10 is vertically hinged to the first support 1, and the other arm 10 is vertically hinged to the second support 2, forming a first hinge axis, that is, the first hinge axis is placed vertically. The bending plate 5 is formed by hinged two equal-sized plates 9, allowing it to be folded in the middle. One plate 9 is horizontally hinged to the first support 1, and the other plate 9 is horizontally hinged to the second support 2, forming a second hinge axis. The second hinge axis is placed horizontally. Thus, one end of the bending arm 6 is vertically hinged to the first support 1, and the other end is vertically hinged to the second support 2. One end of the bending plate 5 is horizontally hinged to the first support 1, and the other end is horizontally hinged to the second support 2, so that the second hinge axis and the first hinge axis form a cross shape. This allows for complete folding, stable support for the first support 1 and the second support 2, and also allows the bending plate 5 to be used as a storage platform when open, improving the practicality of the folding frame.

[0030] To further enhance the stability of the folding frame, two folding arms are designed, each bending inwards to bend towards the other, preventing the folding frame from becoming too long when folded. Two legs 3 are also provided on the first support 1 and the second support 2, and two cross braces 4 are also provided on each support 1 and the second support 2. One end of each cross brace 4 is connected to one leg, and the other end is connected to the other leg 3. The two cross braces 4 are arranged sequentially from top to bottom. With this configuration, the bending arms 6 and bending plates 5 are installed on the corresponding legs 3, ensuring the bending arms 6 bend inwards and preventing the folding frame from becoming too long when folded. Finally, a caster wheel 7 is installed on each leg 3, and a brake 8 is fitted on each caster wheel 7.

[0031] This utility model also installs a tabletop 11 on the aforementioned folding frame to form a folding table, a folding workbench, or other folding device. Specifically, for example... Figure 4 As shown, a groove is formed on the bottom wall of the tabletop 11. The top ends of the first bracket 1 and the second bracket 2 are inserted into the groove, so that the groove has a circumferential limiting effect on the top end of the folding frame, enhancing the stability of the folding device. Two opposing support arms 12 are also provided on the first bracket 1. The tabletop 11 is hinged to the support arms 12, allowing the tabletop 11 to be folded to one side of the folding frame, which facilitates the installation of the folding device and reduces the space occupied by the folding device after folding. Figure 5 As shown, the tabletop 11 is provided with a pin 13. The tabletop 11 is connected to the second bracket 2 through the pin 13, which can realize the relative fixation between the tabletop 11 and the folding frame and facilitate operation.

[0032] A stove can also be installed on the countertop 11, so that the folding rack can be used as a stove rack, which can meet the cooking needs when picnicking and expand the scope of use.

[0033] The aforementioned hinge can be achieved through a hinge, a pin inserted through a pin hole, or other existing methods that enable hinges, as long as a rotational connection can be achieved through the hinge; it is not limited to a specific implementation method. The caster wheel 7 and the brake 8 are mature existing technologies, and specific details can be found in the technologies disclosed in utility models with publication numbers CN221206223U and CN115634052A, so they will not be elaborated upon here.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments.
