Description

Technical Field

[0001] The present application relates to the technical field of folding tables, and in particular to a portable folding table. Background Art

[0002] As living conditions improve, people tend to go out to play and have picnics in the wild during leisure time. It is not convenient to eat or play some table games in the wild without a table. If you bring a table with you, it is not easy to put it in the car or carry it because it is too big. Therefore, people will choose a folding table to reduce the floor space.

[0003] In existing products, the legs of a folding table can generally be folded and placed under the table top to reduce the folded volume. When people go out to play, it is much more convenient to bring such a folding table. On the other hand, because the folded volume of the folding table is small, it is also more convenient to store and organize.

[0004] Related prior art such as Chinese patent application "A portable folding table", application number: CN201520025259.1; discloses that its structure is simple, not only light and easy to carry, no need to be tied with ropes, and can effectively wrap the table frame part to prevent dirt and damage; it includes a desktop and a table frame part, the desktop and the table frame part are detachably connected, the table frame part includes a bracket supporting the desktop, each bracket is provided with a connecting base at the bottom, a tablecloth parallel to the desktop is provided on the bracket below the desktop, an X-shaped bracket is connected to the adjacent bracket below the tablecloth, the middle part of the two legs of the X-shaped bracket is movably connected, the upper end of the X-shaped bracket is connected to the adjacent bracket below the tablecloth, the lower end of the X-shaped bracket is connected to the connecting base at the bottom of the corresponding adjacent bracket, the lower surface of the tablecloth is provided with felt and barbs, and the felt and barbs are woven on the lower surface of the tablecloth at intervals.

[0005] The desktop structure of the above structure can be portable after being stored. However, the stability of the structure is poor when the structure is in the open state, and the inventor of the present application believes that further improvements can be made. Utility Model Content

[0006] The technical problem to be solved by the present application is to provide a portable folding table and optimize the product structure design so that the product has good stability and reliability while being lightweight.

[0007] The technical solution adopted in the present application is: a portable folding table, including a desktop assembly and two brackets respectively connected to the left and right sides of the desktop assembly, the desktop assembly includes two support rods arranged parallel to each other, the support rods are covered with supporting cloth, the bracket is a U-shaped structure, the two ends of the bracket are respectively connected to the end of the support rod through connecting members, the bracket is hinged to the connecting member, and the bracket is subjected to force to rotate relative to the connecting member to be parallel to the support rod or to form a predetermined angle with the support rod, and the predetermined angle is greater than or equal to 90 degrees.

[0008] Compared with the prior art, the advantages of the present application are that, firstly, the present application uses two support rods to open the support cloth to form a desktop where items can be placed. Compared with the prior art, the present application uses two support rods and support cloth, and its product is lighter. Secondly, the present application adopts a U-shaped structure when designing the bracket of the folding table. The bracket of the U-shaped structure itself has good structural strength, and in the present application, the bracket plays a role in supporting the distance between the two support rods, thereby opening the support cloth to form a stable plane structure. The design of the bracket also saves the need for an additional support structure for the desktop assembly. The lightness of the product is further improved. Thirdly, the present application only designs the bracket to be hinged with the connecting member, so the support rod and the connecting member are fixedly connected, which effectively improves the stability and reliability of the product when in use. The bracket is rotated relative to the connecting member to be parallel to the support rod or to form a predetermined angle with the support rod, that is, the folding storage state and the open use state of the present application are realized. The predetermined angle is greater than or equal to 90 degrees, so in the open state, the structure of the present application is relatively stable and is not easily deformed due to accidental contact with external force.

[0009] In some embodiments of the present application, the connecting member is a curved sheet-like structural member, the first end of the connecting member is fixedly connected to the support rod, the second end of the connecting member is hinged to the bracket, and the first end and the second end of the connecting member are staggered up and down.

[0010] The above structural setting firstly makes the connection structure between the connecting piece and the support rod stable, and there will be no relative movement between the connecting piece and the support rod, thereby improving the stability and reliability of this part of the connection structure. Secondly, the present application uses the connecting piece to stagger the connection point of the support rod and the connection point of the bracket up and down, so that after the bracket is folded, it can fit under the support rod and be parallel to the support rod to achieve the storage of the surface structure. Avoid interference between the bracket and the support rod in the folded state.

[0011] In some embodiments of the present application, the two end faces of the bracket are provided with slots adapted to the connecting member, the second end of the connecting member is embedded in the slot, and the connecting member and the slot cooperate with each other to limit the maximum angle of rotation of the bracket relative to the connecting member.

[0012] In some embodiments of the present application, the second end of the connecting member includes a lower bottom surface, a first side surface and a second side surface, the first side surface is arranged closer to the support rod than the second side surface, and the first side surface and the lower bottom surface are transitioned by a curved surface. That is, the above structure enables the bracket in the folded state to be flipped outward relative to the support rod to the expanded state.

[0013] In some embodiments of the present application, the second side surface is a plane, the lower bottom surface of the connecting member is a plane, the bottom surface and the second side surface are connected at a right angle or an acute angle, and the inner bottom surface of the notch is a plane.

[0014] That is, the above-mentioned structural arrangement ensures that when the bracket is flipped over to the point where the inner bottom surface of the slot is parallel to the lower bottom surface of the connector, or in other words, in a contact state, the bracket reaches the limit position of the travel and is limited by the right angle or acute angle between the bottom surface and the second side surface, and the bracket cannot continue to flip outward.

[0015] The present application provides relative rotation limitation between the connector and the bracket through the design of the connector structure, and the cost of this solution is relatively low.

[0016] In some embodiments of the present application, the support rod and the bracket are both hollow circular tube structures, and plugs are installed at both ends of the support rod and both ends of the bracket. One end of the plug is fixed to the bracket or the support rod, and the other end of the plug is connected to the connecting piece.

[0017] In some embodiments of the present application, the plug is a solid structure, and the notch is provided on the plug. In the present application, a hollow round tube is used to make the support rod and the bracket, so that the overall structure of the present application is light and convenient for users to carry. At the same time, the structural strength of the folding table, the stability and reliability of the connection structure must be taken into consideration, so a plug with a solid structure is installed at the end of the support rod and the bracket to meet the structural strength requirements of the folding table.

[0018] In some embodiments of the present application, the supporting cloth is made of Oxford cloth.

[0019] In some embodiments of the present application, at least one circular hole and at least one strip hole are formed on the surface of the supporting cloth, a circular net bag is connected below the circular hole, and a square net bag is connected below the strip hole.

[0020] In this application, the circular hole structure is suitable for cylindrical objects such as water cups, and the water cups can be well confined to the desktop component through the sunken circular net bag, without worrying about them tipping over. The strip hole is used to adapt to flat structures such as mobile phones, and similarly, it can also ensure the reliability of the mobile phone after placement.

[0021] In some embodiments of the present application, the outer edge of the connecting piece is an arc surface. This structure makes the present application relatively smooth at the movable joint, and the user will not be injured if the user touches it by mistake, and the user feels good when using it.

[0022] The above-mentioned implementation modes can be combined arbitrarily based on the common knowledge in the art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present application is described in detail below in conjunction with the accompanying drawings.

[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] A portable folding table, embodiment 1 Figures 1 to 4As shown: it includes a desktop component and two brackets 1 connected to the left and right sides of the desktop component respectively. The desktop component includes two support rods 2 arranged in parallel with each other, and the support rods 2 are covered with a support cloth 3. Compared with the prior art, the present application adopts two support rods 2 and a support cloth 3, and the product is lighter. The bracket 1 is a U-shaped structure. The U-shaped bracket 1 itself has good structural strength. In the present application, the bracket 1 plays a role in supporting the distance between the two support rods 2, thereby stretching the support cloth 3 to form a stable plane structure. The design of the bracket 1 also saves the need for additional support structures for the desktop component. The two ends of the bracket 1 are respectively connected to the ends of the support rod 2 through a connecting member 4. The bracket 1 is hinged with the connecting member 4, and the support rod 2 and the connecting member 4 are fixedly connected, which effectively improves the stability and reliability of the product when in use. The bracket 1 is rotated relative to the connecting member 4 to be parallel to the support rod 2 or to be at a predetermined angle with the support rod 2, that is, the folding storage state and the stretched use state of the present application are realized. The predetermined angle is greater than or equal to 90 degrees. Then, in the expanded state, the structure of the present application is relatively stable and is not easily deformed by accidental contact with external forces.

[0032] Embodiment 2, as Figures 1 to 4 As shown, the connector 4 is a curved sheet-like structural member, the first end of the connector 4 is fixedly connected to the support rod 2, the second end of the connector 4 is hinged to the bracket 1, and the first end and the second end of the connector 4 are staggered up and down. The above-mentioned structural arrangement firstly makes the connection structure between the connector 4 and the support rod 2 stable, and there will be no relative movement between the connector 4 and the support rod 2, thereby improving the stability and reliability of this part of the connection structure. Secondly, the present application uses the connector 4 to stagger the connection point of the support rod 2 and the connection point of the bracket 1 up and down, so that after the bracket 1 is folded, it can fit under the support rod 2 and be parallel to the support rod 2 to achieve the storage of the surface structure. Avoid mutual interference between the bracket 1 and the support rod 2 in the folded state. In the present application, the structure of the connector 4 can be thickened to enhance the structural strength of its connection and further improve the load-bearing capacity of the present application.

[0033] The two end faces of the bracket 1 are provided with slots 5 adapted to the connector 4 , the second end of the connector is embedded in the slot 5 , and the connector and the slot 5 cooperate with each other to limit the maximum angle of rotation of the bracket 1 relative to the connector 4 .

[0034] The second end of the connecting member includes a lower bottom surface 6, a first side surface 7 and a second side surface 8, wherein the first side surface 7 is arranged closer to the support rod 2 than the second side surface 8, and a curved surface transition is formed between the first side surface 7 and the lower bottom surface 6. That is, the above structure enables the bracket 1 in the folded state to be flipped outward relative to the support rod 2 to the expanded state.

[0035] The second side surface 8 is a plane, the lower bottom surface 6 of the connector is a plane, the bottom surface and the second side surface 8 are connected at a right angle or an acute angle, and the inner bottom surface of the notch 5 is a plane. That is, the above-mentioned structure is set so that when the bracket 1 is flipped over to the point where the inner bottom surface of the notch 5 is parallel to the lower bottom surface 6 of the connector, or in other words, in a contact state, the bracket 1 reaches the limit position of the stroke, and is limited by the right angle or acute angle between the bottom surface and the second side surface 8, so that the bracket 1 cannot continue to flip outward. The present application has a relative rotation limit between the connector and the bracket 1 through the design of the connector structure, and the cost of this solution is relatively low.

[0036] The support rod 2 and the bracket 1 are both hollow circular tube structures, and plugs 9 are installed at both ends of the support rod 2 and both ends of the bracket 1. One end of the plug 9 is fixed to the bracket 1 or the support rod 2, and the other end of the plug 9 is connected to the connecting piece. The plug 9 is a solid structure, and the notch 5 is provided on the plug 9. In the present application, hollow circular tubes are used to make the support rod 2 and the bracket 1, so that the overall structure of the present application is lighter and convenient for users to carry. At the same time, the structural strength of the folding table, the stability and reliability of the connection structure must be taken into consideration. Therefore, a plug 9 with a solid structure is installed at the ends of the support rod 2 and the bracket 1 to meet the structural strength requirements of the folding table.

[0037] In the present application, high processing precision is used to form the support rod 2, the bracket 1, and the plug 9, so that the plug 9 is better connected with the support rod 2 and the bracket 1, and the stability and reliability of the connection joint are improved. In addition, the support rod 2 and the bracket 1 of the circular tube structure in the present application can be thickened to improve the structural strength of the product and further improve the load-bearing capacity of the product.

[0038] In addition, the materials used to form the bracket 1, the support rod 2, the plug 9 and the connecting piece 4 in the present application have undergone high-temperature heat treatment, thereby further improving the structural strength of the material and thus increasing the maximum load-bearing capacity of the product.

[0039] The rest of the content of the second embodiment is the same as that of the first embodiment.

[0040] Embodiment three, as Figures 1 to 4 As shown, the support cloth 3 is made of Oxford cloth. The support cloth 3 has at least one circular hole 10 and at least one strip hole 11 on its surface. A circular net bag 12 is connected below the circular hole 10, and a square net bag 13 is connected below the strip hole 11.

[0041] In the present application, the circular hole 10 is adapted to cylindrical objects such as a user's water cup, and the water cup can be well confined to the desktop component through the sunken circular net bag 12, without worrying about it tipping over. The strip hole 11 is used to adapt to flat structures such as a user's mobile phone, and similarly, it can also ensure the reliability of the mobile phone after placement.

[0042] The outer edge of the connecting piece is an arc surface. This structure makes the joints of the present application relatively smooth, and the user will not be injured if the user touches it by mistake, and the user feels good when using it.
