Description

Technical Field

[0001] This utility model relates to the field of outdoor camping table technology, and in particular to a camping table that supports desktop expansion. Background Technology

[0002] A folding table is a type of table that can be easily folded for convenient packaging and transportation. It is suitable for a wide range of scenarios, whether it is a temporary extra seat for family gatherings, outdoor storage for picnics and camping, or a temporary workbench for business activities. It can flexibly meet the needs of various scenarios and provide convenient desktop support.

[0003] Traditional folding tables, once unfolded, have a fixed tabletop size, making them difficult to adapt to different usage scenarios and exhibiting significant limitations. To overcome this technical challenge, folding tables with adjustable tabletop sizes have emerged on the market. For example, a multi-functional folding table with adjustable unfolded size disclosed in Chinese Utility Model Patent (Authorization Announcement No.: CN220458842U) includes a first outer table panel, a first inner table panel, a second inner table panel, and a second outer table panel. These panels are detachably installed and combined via pins, allowing the device to be assembled into large tables, small tables, and even a folding table for vehicle tailgates. Furthermore, it has a relatively small thickness when folded, solving the problems of current products lacking size adjustment when unfolded and occupying a large amount of space when folded, thus achieving multi-purpose functionality.

[0004] However, the adjustment method of the multi-functional folding table with adjustable unfolded size disclosed in the above-mentioned prior art is quite complicated. It requires disassembling the tabletop that is not in use for the time being and then reassembling the tabletop that needs to be used. The whole operation is cumbersome, which not only consumes a lot of time and energy, but may also cause wear and tear on the parts due to frequent disassembly and assembly, affecting the service life and stability of the table and causing a lot of inconvenience to users.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

The expandable desktop can be unfolded and folded relative to the main desktop. When the expandable desktop is unfolded relative to the main desktop, it cooperates with the main desktop to form the usable desktop of the camping table. When the expandable desktop is folded relative to the main desktop, it is stacked on top of the main desktop, and the expandable desktop, or a portion thereof, cooperates with the main desktop to form the usable desktop of the camping table. A folding structure is provided between the expandable desktop and the main desktop. The folding structure includes a first connecting rod, a second connecting rod, and a limiting member. The first and second connecting rods are arranged in parallel, and their ends are respectively hinged to the main desktop and the expandable desktop. The limiting member is located on the side of the main desktop. When the expandable desktop is unfolded relative to the main desktop, the second connecting rod abuts against the limiting member.

[0008] Furthermore, the first link and the second link are of the same length, and the two ends of the first link and the second link respectively form four hinge points with the hinge points of the main desktop and the extended desktop, and the lines connecting the four hinge points form a parallelogram.

[0009] Furthermore, the limiting component is a limiting pin, and the second connecting rod is provided with a limiting angle. When the extended desktop is in an unfolded state relative to the main desktop, the limiting angle and the limiting pin abut against each other.

[0010] Furthermore, there are two extended desktops, which are respectively set on opposite sides of the main desktop along the first direction.

[0011] Furthermore, the width of the extended desktop along the first direction is half the width of the main desktop along the first direction.

[0012] Furthermore, when the extended desktop is folded relative to the main desktop, both extended desktops are stacked on top of the main desktop, and the two extended desktops work together to form the usage surface of the camping table.

[0013] Furthermore, when the extended desktop is in an unfolded state relative to the main desktop, the extended desktop is flush with the top surface of the main desktop.

[0028] like Figures 1 to 7 As shown, a camping table supporting desktop extension includes a main desktop 1 and an extension desktop 2. The extension desktop 2 can be unfolded and folded relative to the main desktop 1. When the extension desktop 2 is unfolded relative to the main desktop 1, the extension desktop 2 and the main desktop 1 cooperate to form the usable desktop of the camping table. When the extension desktop 2 is folded relative to the main desktop 1, the extension desktop 2 is stacked on top of the main desktop 1, and the extension desktop 2, or a portion of the extension desktop 2 and the main desktop 1 cooperate to form the usable desktop of the camping table. A folding structure 3 is provided between the extension desktop 2 and the main desktop 1. The folding structure 3 includes a first connecting rod 31, a second connecting rod 32, and a limiting member 33. The first connecting rod 31 and the second connecting rod 32 are arranged in parallel, and their two ends are respectively hinged to the main desktop 1 and the extension desktop 2. The limiting member 33 is provided on the side of the main desktop 1. When the extension desktop 2 is unfolded relative to the main desktop 1, the second connecting rod 32 and the limiting member 33 abut against each other.

[0029] Based on the above embodiments, this utility model provides a camping table that supports desktop expansion, including a main desktop 1 and an extended desktop 2. The extended desktop 2 can be unfolded and folded relative to the main desktop 1. A folding structure 3 is provided between the extended desktop 2 and the main desktop 1. The folding structure 3 includes a first connecting rod 31, a second connecting rod 32, and a limiting member 33. This utility model realizes the unfolding and folding of the extended desktop 2 relative to the main desktop 1 by means of the folding structure 3, thereby realizing flexible adjustment of the size of the camping table. Moreover, the adjustment process does not require any tools and can be completed with simple operation. This not only simplifies the adjustment steps but also significantly improves the convenience of use, allowing users to quickly adjust the desktop size according to the actual needs of camping (such as the number of people or the amount of items), easily meeting the usage needs in different scenarios.

[0030] In another preferred embodiment of this utility model, the first connecting rod 31 and the second connecting rod 32 are of the same length, and the two ends of the first connecting rod 31 and the second connecting rod 32 respectively form four hinge points with the hinge points of the main desktop 1 and the extended desktop 2, and the lines connecting the four hinge points form a parallelogram. In this embodiment, as... Figure 2 and Figure 5 As shown, this structural design ensures that the first link 31 and the second link 32 will never interfere with each other during movement. Furthermore, the parallelogram structure ensures that the extended tabletop 2 maintains a stable posture during movement. For example, when the first link 31 moves as the active component, the corresponding second link 32 remains parallel, and the extended tabletop 2 connected to it maintains its original horizontal posture without tilting or twisting. Therefore, even when items are placed on the extended tabletop 2, the usage surface of the camping table can still be adjusted, improving the convenience of adjusting the camping table. The state of the extended tabletop 2 during adjustment is as follows: Figure 3 As shown. At the same time, the double-link design of the first link 31 and the second link 32 can evenly distribute the force, reduce the force requirement of a single link, improve the overall stability and durability of the folding structure 3, and make the movement trajectory of the extended tabletop 2 regular, avoiding interference with other objects during movement.

[0031] In another preferred embodiment of this utility model, the limiting member 33 is a limiting pin, and the second connecting rod 32 is provided with a limiting angle 321. When the extended tabletop 2 is in an unfolded state relative to the main tabletop 1, the limiting angle 321 abuts against the limiting pin. The second connecting rod 32 is provided with a widening portion 322, and the limiting angle 321 is disposed in the widening portion 322. In this embodiment, as... Figure 2 and Figure 7As shown, the combined action of the first link 31, the second link 32, and the limiting member 33 ensures that the extended tabletop 2 has good load-bearing capacity. The second link 32 is provided with a widened portion 322, and the limiting angle 321 is located at the widened portion 322. This structural design can effectively enhance the stress performance and rigidity of the second link 32, thereby helping to extend the service life of the second link 32.

[0032] As another preferred embodiment of this utility model, two extendable desktops 2 are provided, each corresponding to one of the two opposite sides of the main desktop 1 along the first direction. The width of each extendable desktop 2 along the first direction is half the width of the main desktop 1 along the first direction. When the extendable desktops 2 are folded relative to the main desktop 1, both extendable desktops 2 are stacked on top of the main desktop 1, and the two extendable desktops 2 cooperate to form the usable surface of the camping table. In this embodiment, as... Figure 4 As shown, when the usable surface of the camping table needs to be reduced, the extended tabletop 2 is lifted and folded inward until it overlaps the main tabletop 1. Since the width of the extended tabletop 2 along the first direction is half the width of the main tabletop 1 along the first direction, when both extended tabletops 2 are folded, they completely cover the main tabletop 1, forming a new usable surface. In this embodiment, the first direction is the length direction of the main tabletop 1.

[0033] As another preferred embodiment of this utility model, when the extended desktop 2 is in an unfolded state relative to the main desktop 1, the extended desktop 2 is flush with the upper surface of the main desktop 1. In this embodiment, as... Figure 1 As shown, the extended desktop 2 and the main desktop 1 work together to form the usable surface of the camping table. The two are seamlessly connected to form a complete tabletop, which not only expands the usable space but also meets the needs of placing various items such as food, tableware, and camping equipment during camping, providing a convenient and practical operating platform for camping scenarios. In this embodiment, when both extended desktops 2 are extended, the usable surface area of ​​the camping table doubles.

[0034] In another preferred embodiment of this utility model, the main desktop 1 and the extended desktop 2 are each provided with a receiving slot 11. A desktop panel 12 is installed in the receiving slot 11. In this embodiment, as... Figure 1 and Figure 6As shown, a tabletop 12 is installed within the receiving slot 11. The tabletop 12 can be either a perforated or solid surface, each with its own advantages: a perforated surface, with its transparent structure, effectively promotes air circulation, making it particularly suitable for placing items requiring ventilation and heat dissipation; its lightweight texture also makes installation and movement more convenient. A solid surface, on the other hand, exhibits stronger load-bearing capacity with its robust overall structure, and its smooth, flat surface facilitates the stable placement of various items, providing a solid and flat support surface for activities such as dining. In other preferred embodiments, the receiving slot 11 can also accommodate a standard-sized outdoor tea tray. This design cleverly expands the usage scenarios of the camping table, easily handling both outdoor tea tasting during camping and tea set storage during outdoor meals, significantly enhancing the applicability and practical value of the camping table.

[0035] As another preferred embodiment of this utility model, it further includes a support rod 4, which is connected to the main desktop 1 and / or the extended desktop 2, and a desktop panel 12 is mounted on the support rod 4. In this embodiment, as... Figure 6 As shown, the main desktop 1 and / or the extended desktop 2 are provided with sockets, and the support rod 4 is connected to the sockets by a plug-in method. By installing the desktop panel 12 on the support rod 4, the space for placing items can be increased; hooks 41 can also be installed on the support rod 4 for hanging items.

[0036] As another preferred embodiment of this utility model, table legs 5 are provided at each of the four corners of the main desktop 1. In this embodiment, as... Figure 1 As shown, the table legs 5 are used to support the main tabletop 1, and the table legs 5 have a telescopic function. When in use, the user can adjust the height of the table legs 5 according to actual needs, so that the camping table can adapt to different usage scenarios, greatly improving the practicality and flexibility of the camping table.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
