Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0048] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] See Figures 1-6 As shown, an embodiment of the utility model provides a tent frame, including a connecting seat 1, a center column 2 and a support assembly 3. The center column 2 is coaxially arranged above the connecting seat 1, and the center column 2 is detachably connected to the connecting seat 1 to adjust the axial position of the center column 2 relative to the connecting seat 1, so that the center column 2 can be separated from the connecting seat 1, and can also be inserted into the connecting seat 1 along its axial direction. When the center column 2 is inserted into the connecting seat 1, the connection and fixation of the center column 2 and the connecting seat 1 are achieved by the built-in positioning marbles of the center column 2; the support assembly 3 is provided with at least three groups, and at least three groups of support assemblies 3 are arranged at intervals along the circumference of the connecting seat 1; the support assembly 3 is hingedly connected to the connecting seat 1 and the center column 2 respectively.

[0050] The support assembly 3 includes a column 31 and a crossbeam 32. One end of the crossbeam 32 is hingedly connected to the column 31, and the other end of the crossbeam 32 is hingedly connected to the connecting base 1. A first connecting rod 33 is hingedly connected below the crossbeam 32, and a second connecting rod 34 is hingedly connected above the crossbeam 32. The end of the first connecting rod 33 away from the crossbeam 32 is detachably connected to the column 31, so that the crossbeam 32, the first connecting rod 33, and the column 31 form a first triangular support structure. The end of the second connecting rod 34 away from the crossbeam 32 is hingedly connected to the center column 2. The first triangular support structure, the second connecting rod 34, and the center column 2 are coplanar. The crossbeam 32 can rotate and fold relative to the connecting base 1 and the column 31. The first connecting rod 33 can rotate and fold relative to the crossbeam 32, and the second connecting rod 34 can rotate and fold relative to the crossbeam 32 and the center column 2.

[0051] The tent frame has a folding state, a first supporting state and a second supporting state. When the tent frame is in the folding state, each supporting assembly 3 is respectively attached to the central column 2; when the tent frame is in the first supporting state, each supporting assembly 3 is unfolded relative to the central column 2 and forms an umbrella-shaped frame with the central column 2. At this time, each supporting assembly 3 is in a suspended state, and the tent frame is supported solely by the central column 2; when the tent frame is in the second supporting state, the central column 2 is connected to the connecting seat 1, and the second connecting rod 34, the central column 2 and the crossbeam 32 form a second triangular supporting structure. The first triangular supporting structure and the second triangular supporting structure are coplanar and respectively located on opposite sides of the crossbeam 32; the first triangular supporting structure and the second triangular supporting structure of each supporting assembly 3 are unfolded relative to the central column 2 to form a vertical frame, and the central column 2 is suspended by each supporting assembly 3. At this time, the tent frame is jointly supported by the supporting assemblies 3.

[0052] The tent frame can be placed in a folded position for easy storage. When the tent frame is in the first support position, the resulting umbrella-shaped frame can be used to create an umbrella. When the tent frame is in the second support position, the resulting vertical frame can be used to create tents, canopies, pavilions, and more. The tent frame of this application can have a variety of variations and, when combined with outer coverings featuring sunscreen, water resistance, and insect repellency, can be used to create umbrellas, tents, canopies, and other products, achieving different functions. This allows for multiple uses, providing users with more options.

[0053] When the support assembly 3 is deployed relative to the center column 2 and the center column 2 is in the first predetermined axial position relative to the connecting base 1, the support assembly 3 assumes a first supporting state, allowing the tent frame to form an umbrella-shaped framework. The umbrella, consisting of the umbrella-shaped framework and the corresponding umbrella canopy, is supported by the center column 2. It should be noted that when the support assembly 3 is deployed, it drives the center column 2 to move axially along the connecting base 1 until the center column 2 reaches the first predetermined position and then locks, securing the support assembly 3 in the first supporting state. When the support assembly 3 is deployed relative to the center column 2 and the center column 2 is in the second predetermined axial position relative to the connecting base 1, the support assembly 3 assumes a second supporting state. In this state, the first and second triangular support structures are coplanar, forming a stable support structure. The support structure formed by three or more support assemblies 3 intersects at the center column 2, forming a stable three-dimensional support frame. This allows the tent frame to form a vertical framework, with the center column 2 suspended in the air and supported by the support assemblies 3. Each support assembly 3 is separately connected to the connecting base 1, facilitating the individual removal and replacement of damaged components within each support assembly 3 and improving maintenance convenience.

[0054] See Figure 2 As shown, in some embodiments, the upright posts 31 and / or crossbeam 32 are telescopic sleeve structures, allowing the tent frame to be adjusted in size and height through the expansion and contraction of the sleeve structures. This description will be made using upright post 31 as an example. Upright post 31 includes an inner sleeve 312 and an outer sleeve 311. The outer sleeve 311 is hingedly connected to the crossbeam 32, and the inner sleeve 312 slides within the outer sleeve 311. The overall length of upright post 31 can be adjusted by sliding the inner sleeve 312 relative to the outer sleeve 311. A first connecting rod 33 is connected to the outer sleeve 311. After the inner sleeve 312 slides relative to the outer sleeve 311, it can be locked and secured using a fastener such as a set screw. Alternatively, a marble can be secured by engaging a marble hole. For example, a marble can be elastically connected to the inner sleeve 312, and a marble hole can be provided in the outer sleeve 311. The marble is then locked into the marble hole, securing the inner sleeve 312 to the outer sleeve 311.

[0055] See Figure 3 As shown, in some embodiments, to facilitate the folding and storage of the first connecting rod 33, the first connecting rod 33 and the column 31 can be fixed by a pin 331, which is convenient for both manufacturing and use, and shortens the time required for assembly and disassembly. The first connecting rod 33 can be made of a grooved profile, and the inner cavity can accommodate the crossbeam 32 with an appropriate degree of looseness, effectively solving the rigidity and storage space occupied by the first connecting rod 33. The column 31 and the crossbeam 32 are made of square tubing, and the hinged connection is a π-shaped piece that surrounds and is welded to the outer periphery of the end of the crossbeam 32 and has a hinged piece protruding downward. It can effectively improve the deformation resistance of the crossbeam 32 pipe mouth and improve the space occupied by the pipe cavity. It is also convenient for the production of parts and is also convenient for the placement and use of other parts in the pipe cavity.

[0056] See Figure 4 and Figure 6 As shown, in some embodiments, the support assembly 3 further includes a cantilever 35, which is slidably mounted within the crossbeam 32 and can partially extend out of the crossbeam 32. The crossbeam 32 is provided with a locking member for locking the cantilever 35, which is a set screw 352. By sliding the cantilever 35 out of the crossbeam 32, the length of the crossbeam 32 can be adjusted, facilitating the installation of external components such as the top curtain 5 on the crossbeam 32. The cantilever 35 is slidably connected to the crossbeam 32. After sliding relative to the crossbeam 32, the cantilever 35 can be locked and fixed using the set screw 352, thereby ensuring a stable connection between the cantilever 35 and the crossbeam 32. The exposed end of the cantilever 35 has an anchor point 351. The anchor point 351 facilitates the pulling and extending of the cantilever 35, allowing the cantilever 35 to extend out of the crossbeam 32, and also facilitates the fastening and securing of the top curtain 5 and wind ropes to the anchor point 351. The extension length of the cantilever 35 is different, and the position where the top curtain 5 of the tent frame top outer cover is connected to the cantilever anchor point 351 is different, so that the interval between the outer cover and the edge of the top window net 8 can be different, thereby adjusting the ventilation volume to different levels.

[0057] See Figure 4 and Figure 5 As shown, in some embodiments, the support assembly 3 further includes a foot pad 36, which is rotatably mounted to the bottom of the upright post 31. The foot pad 36 is provided with a receiving slot 361 for accommodating the upright post 31. One end of the bottom of the receiving slot 361 is provided with a mounting hole 362, and the other end of the bottom of the receiving slot 361 is provided with a hook. Two opposing walls of the receiving slot 361 are provided with anchor holes 363. When the support assembly 3 is in the second supporting state, the foot pad 36 can support the support assembly 3, facilitating the attachment of the support assembly 3 to the ground or other mounting platform. The foot pad 36 is rotatably mounted to the upright post 31, allowing the foot pad 36 to be unfolded or folded relative to the upright post 31. When the foot pad 36 is folded relative to the upright post 31, the bottom of the upright post 31 is accommodated within the receiving slot 361 of the foot pad 36, reducing the volume occupied by the tent frame when it is stored. When the foot pad 36 is unfolded relative to the column 31, it can be used to install and fix the umbrella cover 9 in the first support state when it is unfolded at a small angle, and can be used for vertical frame installation in the second support state when it is unfolded at a large angle. The support component 3 can be fixed to the ground or the installation platform through the installation hole 362 by using ground nails or screws, and the hook can be used to fix the ground pad 71 of the outer component; the anchor hole 363 can be used to anchor the wind rope to enhance the stability of the support component 3.

[0058] See Figures 1-4As shown, in some embodiments, the tent frame further includes a connecting plate 4, a connecting column 41 being fixed to the lower surface of the connecting plate 4, the connecting column 41 being inserted into the top of the central column 2 in a manner that allows it to be raised and lowered, and the ends of the second connecting rods 34 away from the crossbeam 32 being hinged to the top periphery of the central column 2. The connecting plate 4 is circular or in other shapes. The connecting plate 4, the connecting column 41, the central column 2, and the connecting seat 1 are coaxially arranged. The connecting column 41 is inserted into the top of the central column 2 in a manner that allows it to be raised and lowered. When the tent frame is in the first supporting state or the second supporting state, the connecting column 41 is pulled out from the central column 2 to raise the height position of the connecting plate 4. The outer covering is supported by the connecting plate 4, so that the highest point of the tent frame has a larger contact surface with the outer covering, thereby avoiding damage to the outer covering caused by the central column 2 supporting the outer covering when the outer covering is matched with the tent frame. The connecting column 41 and the center column 2 can be pulled out, lifted and fixed by the combination of marbles and marble holes. After pulling out the connecting column 41, the marble on the connecting column 41 is inserted into the marble hole set on the center column to fix the connecting column 41 and the center column 2.

[0059] See Figure 3 As shown, in some embodiments, a marble 22 is provided inside the center column 2, and the marble 22 is elastically connected to the center column 2. The connecting seat 1 is provided with a marble hole (not shown in the figure) that matches the marble 22. When the marble 22 extends into the marble hole, the center column 2 and the connecting seat 1 can be locked; when the marble 22 is out of the marble hole, the center column 2 can move relative to the connecting seat 1. The adjustable connection between the center column 2 and the connecting seat 1 is achieved by the cooperation between the marble 22 and the marble hole. The marble 22 can be connected to the center column 2 through elastic parts such as springs. After the marble 22 is connected to the center column 2, it at least partially extends out of the center column 2 so that the marble 22 is stuck in the marble hole. A plurality of marbles 22 can be provided, and the plurality of marbles 22 are spaced apart along the axial direction of the center column 2. By adjusting the position of the marble 2 stuck in the marble hole, the axial position of the center column 2 in the connecting seat 1 can be adjusted. In this embodiment, two marbles 22 are provided, and the center column 2 has two axial positions in the connecting seat 1, namely a first setting position and a second setting position, and the first setting position is lower than the second setting position.

[0060] See Figure 2-Figure 4As shown, when the tent frame is in the second support position, the center column 2 extends axially through the connecting base 1 and extends downward from the connecting base 1. A removable extension 21 is threadedly connected to the bottom of the center column 2. The extension 21 extends axially along the center column 2 and is coaxial with the central axis. When the extension 21 enters the connecting base 1 along the axial direction of the center column 2, it is locked to the connecting base 1. The connecting base 1 restricts the extension 21 to axial movement only and prevents rotation relative to the connecting base 1, preventing uncontrolled separation of the removable threaded connection between the center column 2 and the extension 21. The extension 21 increases the length of the center column 2, facilitating connection to the umbrella's lower column. The extension 21 can be threadedly connected to the center column 2, facilitating installation and removal. The extension 21 and the center column 2 can be configured in a square shape to achieve a removable connection to the connecting base 1. In this case, the extension 21 is provided with a threaded joint and the center column is provided with internal threads to achieve a threaded connection between the two.

[0061] See Figure 3 As shown, in some embodiments, the connecting base 1 is circular and has multiple slots spaced circumferentially thereon. The ends of the crossbeam 32 are inserted into the slots and hingedly connected to the slot walls. The slots allow the crossbeam 32 to be rotated relative to the connecting base 1 and abut against the second connecting rod against the center column 2, thereby minimizing the storage volume of the tent frame.

[0062] The folding process of the above tent frame is as follows:

[0063] 32, and the tent is then folded into a hollow shape.

[0064] See Figure 7-Figure 16As shown, the present invention also provides a shelter device, comprising the tent frame described above and an outer covering, wherein the outer covering is connected to the tent frame. When the tent frame is in a first supporting state, the outer covering is connected to the top of the tent frame to form an umbrella. When the tent frame is in a second supporting state, the outer covering is connected to the upper portion of the tent frame to form a canopy, pavilion, etc. The outer covering can also be enclosed around the outer periphery of the tent frame to form a mosquito net, etc. When the tent frame is in the second supporting state, the outer covering is partially located at the upper portion of the tent frame and partially enclosed around the outer periphery of the tent frame to form a tent, etc.

[0065] When the tent frame is in the folded state, the tent frame is separated from the outer cover, so that the tent frame and the outer cover can be stored separately, thereby facilitating the storage and maintenance of the tent frame and the shelter equipment.

[0066] See Figure 7 As shown, when the tent frame is in the first supporting state, the tent frame forms an umbrella-shaped frame. The outer covering is the umbrella cover 9, which is fixed to the top of the tent frame and forms an umbrella with the tent frame. When making the umbrella, the tent frame is transformed from the folded state to the first supporting state. Specifically, the support components 3 are pulled outward, and the support components 3 drive the central column 2 to move along the axial direction of the connecting seat 1 until the central column 2 is locked in the first set position; the inner sleeve 312 of the column 31 is pulled out, and the first connecting rod 33 is fixed to the column 31 to obtain the umbrella frame. The umbrella cover 9 is fixed to the umbrella frame, and the extension section 21 at the lower end of the central column 2 is connected to the lower column of the umbrella to obtain the umbrella.

[0067] When the tent frame is in the second supporting state, by arranging outer coverings of different structural forms on the tent frame, shielding devices of different structures can be formed to meet different usage requirements.

[0068] See Figure 8As shown, in some embodiments, the outer covering includes a top curtain 5, which is provided at the top of the tent frame and connected to the anchor point 351 at the outer end of the cantilever 35 of the tent frame. At this time, the shielding device formed by the connection between the outer covering and the tent frame is a pavilion. When making a pavilion, the support components 3 are pulled outward, and the support components 3 drive the central column 2 to move along the axial direction of the connecting seat 1 until the central column 2 is locked in the second set position; the extension section 21 at the lower end of the central column 2 is removed by axial rotation, and the cantilever 35 is pulled out to a suitable position, and the top curtain 5 is provided at the top of the tent frame and the corner connectors at each corner position of the top curtain 5 are connected and fixed to the anchor point 351 at the outer end of the cantilever 35 to form a pavilion. Before forming the pavilion, if the top curtain 5 is not connected, the tent frame can also be used as a clothes drying rack. The distance from the midpoint of the edge of the top curtain 5 to its center is greater than the distance from the anchor point 351 of the cantilever 35 to the apex of the center column 2 when the cantilever 35 is fully retracted into the crossbeam 32. This allows the cantilever 35 to be slightly extended outward from its midpoint to the anchor point 351 during use, tightening the top curtain 5 and improving the stability of the connection between the top curtain 5 and the tent frame, thus protecting against adverse weather conditions. Furthermore, the outer covering includes a top window net 8, which is located above the tent frame. The corners of the top window net 8 are connected to the ends of the crossbeam 32 away from the connecting base 1.

[0069] See Figure 9 As shown, in some embodiments, the outer covering includes a top curtain 5, a top window net 8, a ground mat 71, multiple outer tents 6, and multiple inner tents 7. The top curtain 5 is located at the top of the tent frame and connected to the tent frame's cantilever 35. The top window net 8 is located at the top of the tent frame, with its corners connected to the ends of the tent frame's crossbeam 32. The multiple inner tents 7 have detachable sides that are interconnected and surround the tent frame, with their upper bottom edges connected to the sides of the top window net 8 and their lower bottom edges connected to the sides of the ground mat 71. The multiple outer tents 6 have detachable sides that are interconnected and located around the inner tent 7, with their upper bottom edges connected to the sides of the top window net 8. In this case, the outer covering connected to the tent frame forms a tent. A tent can be converted from a gazebo by sequentially hanging the inner tent 7 and the outer tent 6 on the outer periphery of the tent frame to form a tent. The adjacent inner tents 7 and outer tents 6 are connected by side connectors (e.g., zippers). The inner tent 7 is equipped with multiple ventilation holes, similar to a mosquito net. The top curtain 5 is connected to a cantilever 35, which in turn extends from the crossbeam 2. This creates a gap between the top curtain 5 and the edge of the top window net 8. This, combined with the inner tent 7 and top window net 8, ensures ventilation within the tent.

[0070] By changing the installation method of the top curtain 5, the tent can have a warming mode that is windproof, heat-insulating, and sun-heat-retaining, and a cooling mode that is sun-proof, heat-insulating, and ventilated to cool down. Figure 12As shown, when the weather is bad, the cantilever 35 is slightly extended to connect with the midpoint connector of the top curtain 5. The corners of the top curtain 5 are attached to the outer tent downwards. The corner connectors of the top curtain 5 are connected to the ground nails through wind ropes. The top curtain 5 is made of transparent material, which can achieve a warm room mode that is windproof, heat-insulating, and sun-retaining. Figure 11 As shown, when the temperature is high, the top curtain 5 uses a blackout curtain, the cantilever 35 extends a long and appropriate length, the anchor point 351 at its outer end is connected to the corner point connector of the top curtain 5, and the side midpoint connector of the top curtain 5 can be connected to the ground nail through a wind rope when the wind is strong; the lower edge of the outer tent is pulled outward from the ground and fixed, and the gap formed thereby and the top window net serve as the entrance and exit of cool air. The cool air outside the tent can enter the inner tent 7, and the inflow and outflow air can take away the heat radiated inward from the outer tent and the top curtain 5, thereby obtaining a cool mode for sun protection, heat insulation, ventilation and cooling.

[0071] See Figure 13 As shown, in some embodiments, the outer covering includes a top curtain 5, a top curtain extension piece 51, a top window net 8, a ground mat 71, multiple outer tents 6 and multiple inner tents 7. The top curtain 5 is arranged at the top of the tent frame and is connected to the cantilever 35 of the tent frame. The top window net 8 is arranged at the upper part of the tent frame and the corners of the top window net 8 are connected to the ends of the crossbeams 32 of the tent frame. The sides of the multiple inner tents 7 are detachably connected to each other and are surrounded by the outer periphery of the tent frame, and the upper and lower edges of the inner tent 7 are connected to the sides of the top window net 8. The sides of the multiple outer tents 6 are detachably connected to each other and are arranged on the outer periphery of the inner tent 7 and are connected to the sides of the top window net 8. One side of the top curtain extension piece 51 is connected to the top curtain edge of the top curtain 5 located on the upper side of the enclosed inlet and outlet of the outer tent 6. The other side of the top curtain extension piece 51 is fixed by a wind rope and a canopy pole to form a tent with a canopy above the inlet and outlet. When the two are connected to each other through the other sides of the extension piece 51, their inlets and outlets are relative, and a connected tent can be obtained, which can meet more needs. The outer tent 6 is connected at the inlet and outlet via inlet and outlet connectors 63 .

[0072] See Figure 14 As shown, in some embodiments, the outer covering includes a canopy 5, a roof net 8, and multiple flysheets 6. The canopy 5 is located at the top of the tent frame and connected to the anchor points 351 at the outer ends of the tent frame's cantilever 35. The roof net 8 is located at the top of the tent frame, and the corners of the roof net 8 are connected to the ends of the tent frame's crossbeam 32. Each side of the roof net 8 is connected to a flysheet 6. The other side of the flysheet 6 is extended upward and outward relative to the canopy 5. The flysheets 6 are secured by wind ropes and canopy poles. Adjacent sides of the flysheets 6 are not connected. In this case, the shelter formed by the outer covering and the tent frame is a canopy.

[0073] See Figure 15As shown, in some embodiments, the outer covering includes a top window net 8 and multiple outer tents 6. The top window net 8 is arranged on the upper part of the tent frame and the corners of the top window net 8 are connected to the ends of the crossbeams of the tent frame. The sides of the multiple outer tents 6 are detachably connected to each other and surround the outer periphery of the tent frame, and the upper and lower edges of the outer tents 6 are connected to the sides of the top window net 8. A hot air device is provided in the space enclosed by the outer covering, and the shielding device formed by the outer covering and the tent frame can be used as a drying cabinet. Specifically, each support assembly 3 is pulled outward, and the support assembly 3 drives the central column 2 to move along the axial direction of the connecting seat 1 until the central column 2 is locked in the second set position; the extension section 21 at the lower end of the central column 2 is removed, the top window net 8 is arranged on the top of the tent frame, and the outer tent 6 is hung on the outer periphery of the tent frame through the connector at the edge of the top window net. Adjacent outer tents 6 are connected in sequence through side connectors (such as zippers, etc.). It should be noted that when the outer tent 6 is enclosed on the outer periphery of the tent frame, an entrance and exit connected by a connector is reserved on one side for a user to enter the space enclosed by the outer tent 6 .

[0074] See Figure 16 As shown, in some embodiments, the outer cover includes a top window net 8 and multiple inner tents 7, the top window net 8 is provided on the upper part of the tent frame and the corners of the top window net 8 are connected to the ends of the crossbeams of the tent frame, the multiple inner tents 7 are detachably connected to each other on the sides and surround the outer periphery of the tent frame, and the upper bottom edge of the inner tent 7 is connected to the side of the top window net 8, and the lower bottom edge of the inner tent 7 is connected to the side of the ground mat 71. The inner tent 7 is provided with ventilation holes, similar to the structure of a mosquito net. The shielding device formed by the outer cover and the tent frame is a mosquito net, forming a fully enclosed and ventilated space that can be used as a sleeping space or as a mosquito-free work space. It should be noted that when the inner tent 7 is surrounded on the outer periphery of the tent frame, an entrance and exit connected by a connector (such as a zipper) is reserved on one side for users to enter the enclosed space of the inner tent 7.

[0075] In some embodiments, the outer tent 6 includes a first connecting portion 61 and a second connecting portion 62, and the first connecting portion 61 and the second connecting portion 62 are connected vertically. The first connecting portion 61 is made of a waterproof material and is moderately light-transmissive. The second connecting portion 62 is made of a waterproof and heat-insulating material to facilitate sunshade. When the shielding device is a tent, the first connecting portion 61 can be used to allow external light to enter. When the shielding device is a canopy, the corner connector of the top curtain 5 is connected to the anchor point 351 at the outer end of the cantilever 35, and the outer tent 6 is connected to the connector at the edge of the top window net. At this time, the top curtain 5 will partially extend outward from the outer tent 6, so that the first connecting portion 61 of the outer tent 6 is blocked by the top curtain 5, preventing the canopy from being light-transmissive.

[0076] In summary, the embodiments of the present invention provide a tent frame and a shelter device including the same. The tent frame can have various modified forms and can be matched with corresponding outer covering parts with sun protection, waterproof and mosquito-proof properties to produce umbrellas, tents, awnings and other products to achieve different functions, thereby achieving multiple uses of one item and providing users with more usage options.

[0077] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
