Abstract
Description
Technical Field
[0001] This utility model relates to the field of camping equipment technology, specifically to a modular and expandable tent structure. Background Technology
[0002] Most camping tents on the market are freestanding structures, designed to accommodate 2-3 people per tent. These tents typically feature a closed enclosure design, with side walls or doors equipped only with standard zippers or straps for entry, exit, and ventilation. Adjacent tents cannot be directly connected and must maintain independent spacing; limited space expansion is only possible by setting up external awnings or connecting passageways.
[0003] The main drawback is:
[0004] 1. Poor expandability: Traditional tents cannot be directly spliced together, and users cannot flexibly combine multiple tent spaces according to the number of people or needs, resulting in inconvenience in cooperation and low space utilization when camping in groups.
[0005] 2. Limited functionality: Individual tents cannot form a continuous shared area. If multiple people need to participate in activities together (such as meetings, storage, or group rest), they need to repeatedly enter and exit different tents, which is cumbersome.
[0006] 3. Redundancy in connection: If the connection is made through external additional components (such as canopy or channel fabric), additional parts need to be carried and the assembly is complicated, which increases the cost and storage burden. Utility Model Content
[0007] Purpose of the utility model: The technical problem to be solved by this utility model is to provide a splicable and expandable tent structure, which solves the problem that existing tents cannot be spliced in a time-saving and labor-saving manner.

The extension frame is fixedly mounted on the frame and extends out of the frame. The end of the extension frame and the same side of the bottom surface are located on the same vertical plane. An extension surface is provided on the frame. The top of the extension surface extends to the end of the extension frame, and the bottom of the extension surface extends to the vertices on both sides of the same side of the bottom surface. A mating part is provided on the side of the extension surface.
[0011] Furthermore, the skeleton includes a main arc segment and an end arc segment, the main arc segment and the end arc segment are symmetrically arranged, and the end arc segments are symmetrically arranged at both ends of the main arc segment.
[0012] Furthermore, both the main arc segment and the end arc segment are arched structures.
[0013] Furthermore, the arched structure of the main arc segment has its dome located on the upper side with its opening facing downwards.
[0014] Furthermore, the arched structure of the end arc segment has its dome located on the lower side, with the opening facing upwards.
[0015] Furthermore, the skeleton has a closed surface.
[0016] Furthermore, an opening and closing surface is provided between the bottom surface and the frame.
[0017] Furthermore, a window is provided on the closed surface, and a tent door is provided on the opening and closing surface.
[0018] Furthermore, a support frame is fixedly provided between the arched top positions of the main arc-shaped segment.
[0019] Furthermore, the extended surfaces of the tent structure are sequentially and fixedly connected at their ends.
[0020] Beneficial effects
[0021] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0023] Flexible combination: Users can combine 2, 3 or even an unlimited number of tents to form a larger shared space (such as family camping, group activities, etc.) depending on the number of campers or the purpose of the trip.
[0024] Highly adaptable: Suitable for various scenarios, such as outdoor camping, temporary disaster relief housing, and outdoor exhibitions.
[0025] 2. Easy to operate and quick to assemble and disassemble.
[0026] No tools required: Simply align the zipper and pull, and a single person can complete the assembly or disassembly in 10 seconds, greatly saving setup time.
[0027] Immediate assembly and use: No additional accessories (such as connecting channels or canopies) are required, reducing the complexity of use.
[0028] 3. Low-cost modification, strong compatibility
[0029] Compatible with existing tents: Simply add standardized zippers to the front and back sides of a traditional tent; no overall structural changes are required, resulting in low production costs.
[0030] Highly adaptable to various brands and sizes of tents (as long as the zipper specifications are uniform), facilitating market penetration.
[0031] 4. Enhance social interaction and usability
[0032] Enhanced interactivity: When spliced together, it forms a shared channel, facilitating communication among multiple people, and is especially suitable for families or teams.
[0033] Emergency expansion capability: In disaster relief or emergency situations, continuous living space can be quickly constructed to improve resource utilization.

[0039] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0040] Example 1
[0041] Combined with appendix Figure 1-4 A modular and expandable tent structure includes a frame 1 and a tent surface 2 connected by the frame 1. An extension frame 3 is fixed on the frame 1 and an extension surface 4 is fixed together with the frame 1. The tent surface 2 consists of an opening surface 21, a closing surface 22 and a bottom surface 23.
[0042] The skeleton 1 has a symmetrical structure. The skeleton 1 includes a main arc segment 11 for supporting the opening and closing surface 21, and an end arc segment 12 located at the end of the main arc segment 11 for connecting the main arc segment 11. The main arc segment 11 has a symmetrical structure. The main arc segments 11 on both sides have an arched structure. The end arc segment 12 connecting the ends of the symmetrical main arc segments 11 on the same side also has an arched structure. The arch of the main arc segment 11 is located on the upper side with the opening facing downwards, and the arch of the end arc segment 12 is located on the lower side with the opening facing upwards.
[0043] The arched structure of the main arc segment 11 is tilted towards each other, so that the tent surface 2 connected to the frame 1 has a certain tilt angle, which facilitates entry and exit and the illumination of light.
[0044] The frame 1 is integrally connected by the main arc-shaped segments 11 on both sides and the end arc-shaped segments 12 on both sides of the main arc-shaped segments 11. The frame 1 has a closed surface 22 fixedly connected inside the frame 1. Since the frame 1 is an arc-shaped support structure, the closed surface 22 is laid along the arc-shaped structure of the frame 1. Openings that can be partially opened can be provided on both sides of the closed surface 22 as windows.
[0045] The bottom surface 1 is a rectangular bottom surface. The side of the bottom surface 1 is connected to the frame 1 with an opening and closing surface 21. The opening and closing surface 21 is fixed to the frame 1 by the bottom surface 1. Tent doors are symmetrically arranged on the opening and closing surface 21. Both the tent doors and windows are opened and closed by zippers.
[0046] The frame 1 is fixed with symmetrical extension frames 3 mounted on the main arc-shaped segments 11 on both sides. The two ends of the extension frames 3 extend out of the main arc-shaped segments 11 by the same distance, and the two ends of the extension frames 3 are located on the same vertical plane as the side of the bottom surface on the same side.
[0047] The frame 1 is fixedly connected to the end of the extension surface 4 of the extension frame 3. The top of the extension surface 4 is located at the end of the symmetrically arranged extension frame 3. The bottom of the extension surface 4 extends to the vertex of the bottom surface 23 on the same side as the end of the extension frame 3. The extension surface 3 surrounds the outer periphery of the opening and closing surface 21, thereby guiding rainwater and preventing rainwater from dripping directly onto the closing surface 4.
[0048] A support frame 5 is fixedly installed between the arched tops of the main arc-shaped sections 11 on both sides of the frame 1. The support frame 5 is fixedly connected to the highest point of the top of the closed surface 22, thereby achieving the purpose of unfolding the closed surface 22. The support frame 5 is engaged between the main arc-shaped sections 11 on both sides, which can also prevent the main arc-shaped sections 11 on both sides from getting close to each other, thus ensuring the area inside the tent.
[0049] The outer sides of the two extended surfaces 4 are provided with mating parts. The mating parts on the sides of the extended surfaces can be interlocked and connected to each other, thereby realizing the connection of multiple zippers. By setting the mating parts that can be interlocked and connected on both sides of the same tent, when multiple tents are connected, any side of the tent can be connected to the mating side of the tent connected to it, thereby forming a whole.
[0050] The mating parts are either zippers or rotating groove structures. The mating parts are anti-detachment structures, preferably zippers. Zippers can connect either side without distinction, and anti-detachment teeth can be set on the zippers. The rotating groove structure has a groove track on one side of the extended surface and a connecting protrusion on the other side of the extended surface. By inserting the connecting protrusion into the groove track and moving the connecting protrusion within the groove track, the tents can be connected by locking. A press-locking structure can be set on the groove track to achieve the purpose of preventing detachment.
[0051] Multiple tents can be connected into a single unit using the fittings, thus achieving a splicing effect. The outer edge of the extension surface 4 is fixed with a waterproof crotch at the location where the fittings are set, preferably a waterproof baffle. When multiple tents are connected to each other, the extension surface 4, after being connected by the fittings, can provide waterproofing and dustproofing at the connection point.
[0052] When several tents are connected together, the tent door of the inner tent can be opened to facilitate user passage.
[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
