By folding and locking the first pan head and the second pan head, the tent can be turned over and folded, the height of the top support structure can be reduced, and the tent space can be increased.

[0005] In order to achieve the purpose of the invention, the present invention adopts the following technical scheme: a folding pan head, including a plurality of rod joints, the folding pan head includes a first pan head and a second pan head, the first pan head and the second pan head are connected by a rotating shaft; a plurality of bearings matching the rotating shaft are provided on one side of the lower surface of the first pan head and the second pan head; a locking plate is provided on one side of the upper surface of the first pan head, and a locking hole is provided at one end of the locking plate; a protrusion matching the locking hole is provided on one side of the upper surface of the second pan head.

It is very quick and convenient to complete the tent construction, the tent space is also very large, and it is very comfortable to live in.

[0006] Preferably, the bearings of the first disc head and the second disc head are alternately distributed over the entire length of the shaft. This alternating layout can provide more uniform support, reduce local stress concentration caused by concentrated distribution of bearings, and thus improve the service life and rotation balance of the shaft. The length of the shaft is equal to the length of the first disc head and the second disc head. This ensures perfect alignment of the shaft and the disc head, helps to improve the overall symmetry and aesthetics of the structure, and also facilitates installation and alignment. The side surfaces of the first disc head and the second disc head fit together, and the contact surface is a rectangular surface. The connection method between the disc heads is simplified, and the rectangular contact surface provides a larger contact area, which enhances the stability and reliability of the connection.

[0007] Preferably, the rod joint is fixed in the inner groove of the pan head by bolts, and a plurality of volute bolt washers are provided on the upper surface of the first pan head, and each volute bolt washer fixes a bolt, that is, the rod joints of the first pan head are installed independently.

[0008] Preferably, a plurality of rectangular bolt washers are provided on the upper surface of the second pan head, and each rectangular bolt washer fixes two bolts. That is, the rod joints of the second pan head are installed in pairs and cannot be disassembled independently. When encountering external forces, such as strong winds or heavy pressure, this double fixing mechanism can better disperse the force and reduce the burden of a single connection point, thereby reducing the risk of structural damage.

[0009] Preferably, a locking plate is provided on the upper surface of the first pan head near the contact surface, one end of the locking plate is fixed to the upper surface of the first pan head by bolts, and the other end is located outside the first pan head and is provided with a locking hole.

[0010] Preferably, a U-shaped groove is provided on one end of the upper surface of the second disk head near the connecting surface, and the protrusion is arranged in the U-shaped groove. The protrusion can be stuck in the locking hole to achieve rapid locking of the disk head, which is convenient for rapid installation and removal.

[0011] A frame adopts the above-mentioned folding pan head, which reduces the height of the normal structure at the top of the tent frame, makes the space of the tent larger, and facilitates the erection and disassembly of the tent.

[0012] Preferably, a tent frame also includes a plurality of support rods and telescopic rods, one end of the support rod is connected to the telescopic rod through a turning joint, and the other end is installed in the rod joint of the folding pan head. The telescopic rod facilitates disassembly and installation, making the erection and disassembly of the tent more convenient and quick.

[0013] Preferably, one end of some of the support poles is mounted in the pole joint and the other end is connected to the fixing rope. This not only provides additional stability to the tent structure, but also allows a vertical surface to be formed on one side of the tent. This vertical surface is used to set the zipper door, providing an intuitive and easy-to-operate entry and exit channel for users.

[0014] A tent is provided, which uses the above tent frame. The tent is hemispherical, one side of which is a vertical surface. Due to the vertical surface design of the tent, a zipper door can be provided, providing a user with an intuitive and easy-to-operate entry and exit passage. This design not only facilitates the user's entry and exit, but also improves the sealing of the tent, helps to maintain the temperature inside the tent and prevents the invasion of small animals such as insects.

[0015] The beneficial effects of the present invention are as follows: the present invention realizes the flipping and folding of the pan heads by setting a rotating shaft connection between the first pan head and the second pan head, simplifies the tent erection and storage process, reduces the height of the top support structure, makes the tent space larger, and provides users with a more spacious and comfortable living environment; the structural setting of the support rods of the tent frame part makes one side of the tent a vertical surface, which is set as a zipper door for easy entry and exit.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Example 1.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the folding pan head of the present invention connects several rod joints 2.5 to form a mechanical connection system that is both strong and flexible. The folding pan head is divided into two parts: a first pan head 1.1 and a second pan head 1.2. The first pan head 1.1 is connected and fixed to the rod joint 2.5 by a bolt 1.1.3. The volute bolt washer 1.1.2 fixes the bolt 1.1.3 and is arranged on the upper surface of the first pan head 1.1. Each volute bolt washer 1.1.2 fixes a bolt 1.1.3, that is, the rod joints 2.5 of the first pan head 1.1 are all installed independently, that is, each rod joint 2.5 can be disassembled independently. This allows the user to quickly and conveniently perform maintenance on a rod joint 2.5 of the first pan head 1.1 during the use of the tent without disassembling the entire first pan head 1.1 if it is damaged or needs to be replaced. This design greatly improves the availability and maintenance efficiency of the tent, especially in the wild environment, where it is very important to be able to repair it quickly. The design of the volute bolt washer 1.1.2 provides a better locking effect. Each bolt 1.1.3 is fixed by a separate washer, which ensures that each connection point has sufficient pre-tightening force to prevent the bolt 1.1.3 from loosening due to vibration or wind during the use of the tent. This design improves the stability and reliability of the entire tent frame 2 and extends the service life of the tent. The volute bolt washer 1.1.2 is symmetrically arranged along the symmetry axis of the first pan head 1.1. This symmetrical layout is not only beautiful, but also helps to evenly distribute the force and enhance the stability of the entire structure. The bolt 1.1.3 passes through the first pan head 1.1 and fits tightly with the fixed head on the lower surface to form a solid connection point. The side of the first pan head 1.1 is provided with an inner groove 1.1.6, and the inner groove 1.1.6 is provided with two, which are symmetrical along the symmetry axis of the first pan head 1.1. One end of the rod joint 2.5 is arranged in the inner groove 1.1.6 on the side of the first pan head 1.1. The first pan head 1.1 is provided with two rod joints 2.5, which are distributed in two inner grooves 1.1.6 and symmetrically along the symmetry axis of the first pan head 1.1. This design enables the rod joints 2.5 to be evenly distributed when subjected to force, thereby improving the bearing capacity of the entire structure. The second pan head 1.2 is connected and fixed to the rod joint 2.5 by bolts 1.1.3. Rectangular bolt washers 1.2.1 fix the bolts 1.1.3 and are arranged on the upper surface of the first pan head 1.1. Each rectangular bolt washer 1.2.1 fixes two bolts 1.1.3. That is, the rod joints 2.5 of the second pan head 1.2 are installed in pairs and cannot be disassembled independently. Since the rod joints 2.5 are installed in pairs and cannot be disassembled independently, this increases the stability and reliability of the connection point. When encountering external forces, such as strong winds or pressure from heavy objects, this double fixing mechanism can better disperse the force, reduce the burden on a single connection point, and thus reduce the risk of structural damage.This design is particularly suitable for environments that need to withstand strong winds or are frequently used, such as seaside camping or outdoor activities, because each washer fixes two bolts 1.1.3, and it is easier to manage the various components when disassembling. This design provides significant convenience and synchronization when folding and unfolding the tent. Since the two rod joints 2.5 are installed synchronously, they can be folded and unfolded synchronously, which means that the tent can be erected and disassembled more quickly and efficiently. The four corners of the rectangular bolt washer 1.2.1 are rounded, which is both beautiful and can reduce stress concentration. The rectangular bolt washer 1.2.1 is symmetrically arranged along the symmetry axis of the first pan head 1.1. The bolt 1.1.3 passes through the second pan head 1.2 and cooperates with the fixed head on the lower surface to ensure the firmness of the connection. The side of the second pan head 1.2 is provided with an inner groove 1.1.6, and the inner groove 1.1.6 is provided with two, symmetrical along the symmetry axis of the second pan head 1.2. One end of the rod joint 2.5 is arranged in the inner groove 1.1.6 on the side of the second pan head 1.2. The second pan head 1.2 is provided with four rod joints 2.5, which are divided into two groups, and each group of two rod joints are distributed in two inner grooves 1.1.6 and arranged symmetrically along the symmetry axis of the second pan head 1.2. This design enables the second pan head 1.2 to provide more support points when connected, increasing the stability and strength of the entire structure. Two of the rod joints 2.5 fit the side walls of the inner groove 1.1.6, and the direction is parallel to the connecting surface of the first pan head 1.1 and the second pan head 1.2. This design not only ensures the alignment accuracy of the rod joints 2.5 when connected, but also is symmetrical along the direction of the rod hole 1.1.1, further enhancing the symmetry and balance of the entire folded pan head structure.

[0029] like Figure 3As shown, the first pan head 1.1 and the second pan head 1.2 are connected to each other through a rotating shaft 1.3, and the sides can fit together to form a rotatable mechanical structure, which not only provides a stable connection between the pan heads, but also allows the pan heads to rotate within a certain angle range, thereby realizing the flipping and folding function of the pan heads. Such a design avoids the use of drawstrings and springs, simplifies the support structure of the tent, reduces the height of the top support structure, and makes the top support structure basically flat. This flat design increases the internal space of the tent, provides more living space, makes users live more comfortably, and thus improves the living experience. The rotating shaft 1.3 is arranged below the interface where the first pan head 1.1 and the second pan head 1.2 meet, and is equal in length to the first pan head 1.1 and the second pan head 1.2, providing uniform support and balance. On one side of the lower surface of the first disk head 1.1 and the second disk head 1.2, there are several bearings 1.4, which are located below the contact surface. These bearings 1.4 are alternately distributed over the entire length of the rotating shaft 1.3. This alternating layout design helps to provide more uniform support and reduce the local stress concentration caused by the concentrated distribution of the bearings 1.4, thereby improving the service life and rotation balance of the rotating shaft 1.3. The first disk head 1.1 is provided with three bearings 1.4, of which two identical bearings 1.4 are respectively located at the two ends of the first disk head 1.1, and the remaining bearing 1.4 is located at the center of the first disk head 1.1, and the length of the central bearing 1.4 is greater than that of the two end bearings 1.4. This design helps to provide stronger central support and ensure stability when bearing a large load. The second disk head 1.2 is provided with two bearings 1.4, and the two bearings 1.4 are equal in length. They are precisely placed between the two end bearings 1.4 of the first disk head 1.1 and the center bearing 1.4, and their lengths are equal to the distance between the two end bearings 1.4 and the center bearing 1.4. This equidistant distribution design helps ensure the stability and uniform force of the second disc head 1.2 during rotation. All bearings 1.4 have equal diameters and are placed on the shaft 1.3, allowing the disc head to rotate around the shaft 1.3. The setting of bearings 1.4 not only reduces the friction when the disc head rotates, but also ensures the smoothness and stability when the disc head flips, which is crucial to improving the efficiency and reliability of the entire mechanical structure.

[0030] like Figure 1 and Figure 3As shown, a locking plate 1.1.4 is provided on one side of the upper surface of the first pan head 1.1. The locking plate 1.1.4 is located above the joint and is T-shaped, which can realize quick locking between the two pan heads. The T-shaped horizontal end of the locking plate 1.1.4 is fixed to the upper surface of the first pan head 1.1 by two bolts 1.1.3. The two bolts 1.1.3 are respectively located at the two ends of the T-shaped horizontal end of the locking plate 1.1.4, ensuring a firm connection between the locking plate 1.1.4 and the first pan head 1.1. The vertical end of the locking plate 1.1.4 extends to the outside of the first pan head 1.1, so that when the first pan head 1.1 and the second pan head 1.2 are fitted sideways, the vertical end of the locking plate 1.1.4 can be just placed in the U-shaped groove 1.2.2 of the second pan head 1.2, thereby realizing a close fit and locking of the two pan heads. In order to improve the aesthetics of the locking plate 1.1.4 and reduce stress concentration, the corners of the locking plate 1.1.4 are all rounded. A locking hole 1.1.5 is provided at the extended end of the locking plate 1.1.4. The locking hole 1.1.5 is a circular hole, and its size and position are precisely calculated to ensure perfect fit with the protrusion 1.2.3 of the second pan head 1.2. The existence of the locking hole 1.1.5 is the key to achieving the locking of the two pan heads, which allows the protrusion 1.2.3 to be inserted into it to complete the locking action. The locking plate 1.1.4 is symmetrically arranged along the symmetry axis of the first pan head 1.1, which also helps to evenly distribute the force in structure and enhance the stability of the entire mechanism. A U-shaped groove 1.2.2 is provided on one side of the upper surface of the second pan head 1.2. The U-shaped groove 1.2.2 is located above the junction of the first pan head 1.1 and the second pan head 1.2. The positions of the U-shaped groove 1.2.2 and the locking plate 1.1.4 correspond to each other and are symmetrical along the symmetry axis of the second pan head 1.2. The width of the U-shaped groove 1.2.2 is greater than or equal to the width of the horizontal end of the locking plate 1.1.4, and the length is greater than the length of the portion of the locking plate 1.1.4 above the second pan head 1.2. The depth is greater than or equal to the thickness of the locking plate 1.1.4, ensuring that the U-shaped groove 1.2.2 can fully accommodate the vertical end of the locking plate 1.1.4 and provide sufficient support when locked. A protrusion 1.2.3 is provided in the U-shaped groove 1.2.2. The protrusion 1.2.3 is hemispherical, the diameter of the protrusion 1.2.3 is less than or equal to the diameter of the locking hole 1.1.5, and the position is corresponding to the locking hole 1.1.5, allowing the protrusion 1.2.3 to be inserted into the locking hole 1.1.5 on the locking plate 1.1.4 of the first pan head 1.1, thereby achieving the locking of the two pan heads.

[0031] like Figure 1As shown, the folding pan head has two rod holes 1.1.1, which are respectively arranged between the two inner grooves 1.1.6 of the first pan head 1.1 and the second pan head 1.2, and are symmetrically arranged along the symmetry axis of the pan head, which also ensures the uniform distribution of the pan head when subjected to force in terms of structure, and enhances the stability and durability of the entire mechanism. Each rod hole 1.1.1 is provided with an open groove on the upper and lower surfaces, which can save materials and reduce the weight of the pan head. The diameter of the rod hole 1.1.1 perfectly matches the cross-section of the support rod 2.1 and is used to connect the support rod 2.1. The rod joint 2.5 is a cylindrical shape, which helps to evenly distribute the pressure of the support rod 2.1 and reduce local stress concentration. A circular hole is provided in the center of the rod joint 2.5, and the hole diameter is the same as the diameter of the rod hole 1.1.1, which is used to connect the support rod 2.1. The design of the circular hole also allows the support rod 2.1 to rotate freely inside the rod joint 2.5, which is very useful when the support angle or direction needs to be adjusted.

[0032] Example 2.

[0033] like Figure 4As shown, a locking plate 1.1.4 is provided on one side of the upper surface of the first pan head 1.1. The locking plate 1.1.4 is located above the joint and is rectangular, which can realize quick locking between the two pan heads. One side of the rectangular locking plate 1.1.4 is fixed to the upper surface of the first pan head 1.1 by two bolts 1.1.3. The two bolts 1.1.3 are respectively located at the two ends of the short side of the rectangular locking plate 1.1.4, ensuring a firm connection between the locking plate 1.1.4 and the first pan head 1.1. The other end of the locking plate 1.1.4 extends to the outside of the first pan head 1.1, so that when the first pan head 1.1 and the second pan head 1.2 are fitted sideways, the vertical end of the locking plate 1.1.4 can be just placed in the U-shaped groove 1.2.2 of the second pan head 1.2, thereby realizing a close fit and locking of the two pan heads. A locking hole 1.1.5 is provided at the extended end of the locking plate 1.1.4. The locking hole 1.1.5 is a rectangular hole, and its size and position are precisely calculated to ensure perfect cooperation with the protrusion 1.2.3 of the second pan head 1.2. The existence of the locking hole 1.1.5 is the key to achieve the locking of the two pan heads. It allows the protrusion 1.2.3 to be inserted into it to complete the locking action. The locking plate 1.1.4 is symmetrically arranged along the symmetry axis of the first pan head 1.1, which also helps to evenly distribute the force in structure and enhance the stability of the entire mechanism. A U-shaped groove 1.2.2 is provided on one side of the upper surface of the second pan head 1.2. The U-shaped groove 1.2.2 is located above the junction of the first pan head 1.1 and the second pan head 1.2. The positions of the U-shaped groove 1.2.2 and the locking plate 1.1.4 correspond to each other and are symmetrical along the symmetry axis of the second pan head 1.2. The width of the U-shaped groove 1.2.2 is greater than or equal to the width of the rectangular locking plate 1.1.4, and the length is greater than the length of the portion of the locking plate 1.1.4 above the second pan head 1.2. The depth is greater than or equal to the thickness of the locking plate 1.1.4, ensuring that the U-shaped groove 1.2.2 can fully accommodate the vertical end of the locking plate 1.1.4 and provide sufficient support when locked. A protrusion 1.2.3 is provided in the U-shaped groove 1.2.2. The protrusion 1.2.3 is rectangular. The length and width of the protrusion 1.2.3 are less than or equal to the length of the locking hole 1.1.5. The height is greater than the thickness of the locking plate 1.1.4, and the position is corresponding to the locking hole 1.1.5, allowing the protrusion 1.2.3 to be inserted into the locking hole 1.1.5 on the locking plate 1.1.4 of the first pan head 1.1, thereby achieving the locking of the two pan heads.

[0034] like Figure 5 and Figure 6As shown, the tent frame 2 uses a folding pan head 1, which significantly reduces the height of the normal structure on the top of the tent frame 2. This design of reducing the height not only reduces the weight of the entire tent, but also expands the internal space of the tent, providing users with a more spacious and comfortable living environment. In addition, the use of the folding pan head also simplifies the tent erection and disassembly process, allowing users to perform these operations more quickly and conveniently.

[0035] like Figure 6 , Figure 8 and Fig. 9As shown, the flip pan 1 is connected to eight support rods 2.1, which are symmetrically distributed along the center of the flip pan 1, ensuring uniform force and stability of the tent structure. One end of the eight support rods 2.1 is inserted into the rod joint 2.5 or the rod hole 1.1.1, achieving a stable connection with the pan. Among these support rods 2.1, the five support rods 2.1 fixed to the second pan 1.2 are connected to the telescopic rod 2.4 through a turning joint 2.2. The design of this turning joint 2.2 allows the angle between the support rod 2.1 and the telescopic rod 2.4 to be adjusted to adapt to different terrains and usage requirements. The connecting end of the support rod 2.1 is fixedly connected with a joint head 2.2.1, and the joint head 2.2.1 is provided with a limiting groove 2.2.3. The two groove side walls of the limiting groove 2.2.3 are respectively provided with a limiting groove 2.2.3 hinge pin shaft mounting hole, and the connecting end of the telescopic rod 2.4 is provided with a telescopic rod hinge pin shaft hole. The hinge pin shaft 2.2.2 passes through the limiting groove 2.2.3 hinge pin shaft mounting hole and the telescopic rod hinge pin shaft hole, so that the telescopic rod 2.4 is hinged with the joint head 2.2.1. The axial direction of the hinge pin shaft 2.2.2 is perpendicular to the axial direction of the support rod 2.1 and the telescopic rod 2.4. Such a layout provides better torque support and enhances the stability of the structure. One side of the rotation direction of the telescopic rod 2.4 is limited by the bottom of the limiting groove 2.2.3, so that the maximum opening angle of the telescopic rod 2.4 is positioned, thereby ensuring the deployment angle and use effect of the tent. The three support rods 2.1 fixed with the first pan head 1.1 adopt a different connection method. One end of them is not connected to the telescopic rod 2.4, but directly connected to the fixing rope 2.6 through the connecting plate 2.3.1. The three support rods 2.1 are adjacent to each other and serve as the upper end fulcrum of the vertical plane, providing additional stability for the tent. One end of the three support rods 2.1 is provided with a limit head 2.3.2, which passes through a hole at one end of the connecting plate 2.3.1 to complete the connection between the support rod 2.1 and the connecting plate 2.3.1. The width of the end hole of the connecting plate 2.3.1 is slightly larger than the diameter of the support rod 2.1, so that the connecting plate 2.3.1 can rotate within a certain range, which provides convenience for installation. One end of the connecting plate 2.3.1 is provided with a rectangular hole, and one end of the fixing rope 2.6 passes through the rectangular hole, and the other end is connected to the tent cloth, providing an upward pulling force to the tent cloth, so that the tent cloth connected to the three support rods 2.1 can form a vertical plane and ensure that the tent cloth is tight and stable. This vertical plane is very suitable for setting a zipper door because it provides users with an intuitive and easy-to-operate access channel. This layout optimizes the entry and exit process of the tent, allowing users to easily find the entrance even in bad weather or at night when visibility is limited. In addition, the vertical surface design helps protect the zipper door from direct impact from external elements such as rain or wind and sand, thereby increasing the durability and service life of the door. This structure can also enhance the wind resistance and stability of the tent.At the same time, the zipper door design also provides good sealing, which helps to maintain the temperature inside the tent and prevent the invasion of small animals such as insects, providing users with more privacy protection. The vertical surface can better block internal activities and reduce outside prying eyes.

[0036] like Figure 5 and Figure 7 As shown, one end of the telescopic rod 2.4 is connected to the support rod 2.1 through a turning joint 2.2, and the other end is connected to the ground through a fixed joint 2.3 to fix the tent on the ground. The fixed joint 2.3 is provided with an adjustable fixing device, such as a ground nail or a fixing bolt, which can be firmly inserted into the ground to ensure that the tent can remain stable in various environments. This fixing method makes the tent difficult to be blown over even in the case of strong winds, thereby improving the safety and reliability of the tent. A telescopic joint 2.4.1 is provided in the middle of the telescopic rod 2.4, which is the core component for realizing the telescopic function. The upper end of the telescopic joint 2.4.1 is an upper rod, and the lower end is a lower rod. The outer diameter of the upper rod is smaller than the inner diameter of the lower rod, and the upper rod can be freely telescoped inside the lower rod. A clip is provided inside the telescopic rod 2.4, which can firmly lock the upper rod at a specific position of the lower rod when the telescopic button 2.4.2 is not pressed to prevent accidental slipping. To retract the telescopic rod 2.4, the user simply presses the telescopic button 2.4.2, which triggers the clip to withdraw from the bottom of the upper rod, allowing the upper rod to smoothly enter the lower rod, thereby achieving rapid folding of the tent. This process does not require additional tools or complicated operations, greatly simplifying the disassembly process of the tent. The design of the telescopic rod 2.4 makes the tent erection and disassembly process more convenient and quick, thereby quickly completing the tent erection or disassembly.

[0037] like Figure 5As shown, the tent is hemispherical in shape as a whole. This unique shape not only gives people a sense of beauty visually, but also provides significant advantages in functionality. The above-mentioned tent frame 2 is applied, especially the design of the flip pan head 1 is adopted. The top support structure is greatly simplified due to the movement of the above-mentioned flip pan head 1, and its height is reduced to the minimum, almost level with the ground. This design effectively reduces the space occupied by the top support structure, thereby freeing up more space inside the tent and significantly improving the user's living comfort. The tent frame 2 supports the entire tent cloth. The tent cloth is provided with connecting cloth in the middle of each support rod 2.1 and the middle of the upper rod of the telescopic rod 2.4. The connecting cloth is a double-layer structure, the bottom and the top are sealed, the bottom is connected to the tent cloth, and the opening design at both ends allows the support rod 2.1 and the upper rod of the telescopic rod 2.4 to pass through easily, thereby effectively supporting the entire tent cloth and forming the main structure of the tent. One end of the three support rods 2.1 of the first pan head 1.1 is connected to a fixing rope 2.6, which provides the necessary upward pulling force to the top of the vertical surface of the tent, thereby forming a vertical surface. The zipper door on the vertical surface provides users with an intuitive and easy-to-operate access. This design is particularly suitable for family or group camping because it allows multiple people to enter and exit at the same time, improving the practicality and living comfort of the tent. Compared with the traditional vertex or side door design, the vertical surface zipper door provides a larger entrance and exit, making it easier to carry large equipment or food into the tent. The vertical surface consists of a triangle at the top and a rectangle below. The two bottom corners of the upper triangle located on the outside are connected to two ropes respectively, one rope is directly stretched downward and fixed to the ground at the lower end, providing vertical stability for the vertical surface. The other rope is connected to the nearest adjacent fixing joint 2.3, and the connecting fixture is inserted into the ground. This connection method enables the tent to adapt to uneven terrain and maintain structural stability. The design of the tent realizes a stable and comfortable living space through the synergy of its innovative flip pan head 1, support pole 2.1, telescopic pole 2.4 and fixing rope 2.6. This design not only improves the practicality of the tent, but also enhances the user's living experience, providing users with a safe, comfortable and spacious living environment.
