[0002] The structural classification of tents mainly includes support tents, frame tents, folding tents, mesh tents and inflatable tents; among them, frame tents and inflatable tents are currently used more in large-span tents, and inflatable tents are divided into air rib inflatable tents and air bag inflatable tents. The frame tent adopts a unit combination structure, with metal materials as the frame and polymer tarpaulin as the enclosure material. Inflatable tents are divided into air rib inflatable tents and air bag inflatable tents. Among them, the air rib inflatable tent consists of an outer tent, supporting air ribs, and support equipment. The supporting air ribs are composed of interlaced air columns, which form the support structure of the tent after being filled with air. The thermal insulation inner tent and outer tent are laid inside and outside the supporting air ribs respectively. The air bag inflatable tent consists of an air bag body, an outer tent and support equipment. The air bag body adopts a modular structure design, with an air wall structure as the basic unit, and the entire air bag body is composed of a bag body connected by a structure.

[0003] Compared with inflatable tents, the main structure of frame tents is a metal frame, which is fixed to the ground through feet. It has a stable structure, outstanding wind and snow resistance, and high safety. The main structure of the tent is made of metal materials such as aluminum alloy and steel, which are non-combustible materials. The tarpaulin enclosure structure is PVC double-sided coated fabric, which is a flame-retardant material with good fire resistance. At the same time, the tent can be combined and spliced ​​according to the module units to be installed into tents of different shapes and sizes. Overall, frame tents are more suitable for outdoor applications than inflatable tents. However, in actual use, traditional frame tents will find that this structural form has many parts, is difficult to manage, and has complicated on-site erection and withdrawal processes. It has the disadvantages of high labor intensity and long duration. Summary of the invention

[0025] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below.

[0026] The invention provides a large-span frame tent that can be quickly deployed and retracted, comprising a middle frame portion (100), a frame with outriggers (200), a frame without outriggers (300), and a connecting frame (400);

[0027] There are 8 frames (200) with legs in total, and the central one is fixed to the frame connection part (106) in the middle frame part (100). The frames (200) with legs and the frames (300) without legs are arranged alternately on both sides with the frame (200) with legs fixed to the middle frame part (100) as the center.

[0028] The frame with legs (200) and the frame without legs (300) are connected to each other through their respective fixed frames and middle frame fixed bases (212) and connecting long bolts (103), so that the alternately arranged frames can be rotated around the middle frame part (100) as the axis, and finally a circular tent frame is formed.

[0029] The connecting frame (400) is installed between the frame with legs (200) and the frame without legs (300). Specifically, after unfolding, the connecting pins (401) on the connecting frame (400) cooperate with the pin supports (266) on the frame with legs (200) and the frame without legs (300) to connect them, thereby realizing the formation of the overall frame of the tent.

[0030] The middle frame part (100) comprises a middle frame top cap (101), a top cap bracket (102), a side beam limit bracket (103), a connecting bolt (104), a lifting support plate (105), a frame limit base (106), a middle frame body (107) and a frame connecting part (108);

[0031] The middle frame top cap (101) is fixedly connected to the upper end of the middle frame body (107) via a top cap bracket (102).

[0032] The middle frame body (107) is fixed with two side beam limit brackets (103) along the circumferential direction. The side beam limit brackets (103) are mainly used to maintain the shape, so as to ensure that the leg frame can form a circle after rotation and the connecting bolts (104) are perpendicular to the ground.

[0033] The frame limit base (106) is fixed to the lower part of the middle frame body (107), and its main function is to limit the downward displacement of the frames on both sides. The vertical displacement of the frames is limited mainly by the hard contact between the bolt heads of the connecting bolts and the frame limit base. At the same time, the frame limit base is an angled arc surface, which can facilitate the formation of a circular outer contour of the tent when it is unfolded.

[0034] In the side beam limit bracket (103), the limit bracket bottom plate (132), the limit bracket rib plate (133) and the middle frame body (107) are welded, the limit bracket rib plate (133) is located on both sides of the limit bracket bottom plate (132), and the buffer rubber block (131) is glued to the limit bracket bottom plate (132). The lifting support plate (105) is welded to the lower inner part of the middle frame body (107), mainly to cooperate with the lifting device, so as to lift the middle frame part (100), and then lift the entire tent structure to a specified height. In the frame connection part (108), the bolt fixing support (182) cooperates with the middle frame connection support (208), and is fixed with a bolt group (181), so as to fix the central leg frame (200) on the middle frame part (100).

[0035] The frame (200) containing supporting legs comprises a fixed frame (201), a first LED tent light (202), a second LED tent light (203), an interlocking buckle (204), supporting legs (205), a flip frame (206), and a positioning pin (207); the middle frame connecting support (208) only exists in the central frame (200) containing supporting legs that is fixed to the middle frame.

[0036] Among them, the fixed frame (201) and the flip frame (206) are both arranged in the form of a plane truss, and the main body includes a fixed frame vertical web (211), a fixed frame chord (213), a fixed frame oblique web (214) and a flip frame vertical web (262), a flip frame oblique web (263), a flip frame chord (264), and a flip frame connecting web (267), thereby ensuring that the overall bearing performance of the tent structure is reliable.

[0037] The fixed frame (201) and the flip frame (206) are rotatably connected via the fixed frame ear plate (215), the flip frame ear plate (261) and the positioning pin (207). At the same time, after the flip frame (206) is flipped to the unfolded position, the fixed frame (201) and the lower chord of the flip frame (206) are manually connected using the interlocking lock (204). The rubber pad (269) can reduce the impact of the flip frame (206) on the fixed frame (201) when it is flipped to the folded position. The LED tent lights (202) are fixed to the lower chord of the fixed frame (201) to realize the internal lighting function of the tent, and are evenly distributed along the circumference of the tent, ensuring that the illumination distribution is uniform while meeting the required illumination for command and storage. In the supporting leg (205), the upper supporting leg oblique support rod (252) is connected to the lower chord bar ear plate (265) of the flip frame and fixed by a positioning pin (251); the upper supporting leg (255) is connected to the flip frame connecting web bar (267) and fixed by a positioning pin. An adjustment hole is opened on the upper side of the lower supporting leg (254), and the support height of the supporting leg (205) is adjusted by the lower supporting leg (254) and the upper supporting leg (255) in cooperation with the positioning pin. An adjustment hole is opened on the upper side of the lower supporting leg oblique support rod (253), and the support angle of the supporting leg (205) is adjusted by the upper supporting leg oblique support rod (252) and the lower supporting leg oblique support rod (253) in cooperation with the positioning pin. In order to increase the ground contact area, a sheet support seat is designed on the lower side of the lower supporting leg (254) to increase the environmental adaptability of the tent.

[0038] The frame (300) without supporting legs comprises a fixed frame (301), an interlocking lock buckle (302), a flip frame (303), a positioning pin (304), and an LED tent light (305). Each component is the same as the fixed frame (201), the interlocking lock buckle (204), the flip frame (206), the positioning pin (207), and the LED tent light (202) in the frame (200) with supporting legs, and the connection method is also the same, so it is not repeated here.

[0039] In the connecting frame (400), the connecting frame vertical web members (402), the connecting frame oblique web members (403), and the connecting frame chord members (404) are arranged in a plane truss form to ensure the load-bearing performance. The connecting pin (401) is used to connect the frame with outriggers (200) and the frame without outriggers (300).

[0040] The deployment process of the large-span frame tent is as follows:

[0041] When a large-span frame tent is to be unfolded, firstly the integrated bracket module is used to Fig.12 The tent in the folded form shown is transported to the designated location.

[0042] When receiving the deployment command, the first step is to flip the flip frame in the frame with legs and the frame without legs 180° to the deployment position, and fasten the interlocking buckle between the fixed frame and the lower chord of the flip frame to complete the flip. Fig.13 shown.

[0043] The second step is to pull out the positioning pins connecting the lower and upper parts of the legs in the leg frame, pull out the lower legs to the specified position and insert the positioning pins to position them. After completion, the tent will look like this Fig.14 shown.

[0044] The third step is to expand the frame with legs and the frame without legs along the middle frame on both sides, each into a semicircle, and finally form a circular tent outline. And release the tie connection between the legs and the flip frame part, so that the legs are in a free hanging state. After completion, the tent will look like this: Fig.15 Specifically, after unfolding, the connecting pin (401) on the connecting frame (400) is connected with the pin support (266) on the frame with legs (200) and the frame without legs (300), thereby realizing the formation of the overall frame of the tent.

[0045] The fourth step is to use the lifting device on the integrated bracket module to lift the tent to the specified height. During the process, due to the effect of gravity, the legs naturally fall to a position perpendicular to the ground. After reaching the specified position, the lifting mechanism descends, and the 8 legs of the tent support the entire tent, completing the deployment of the large-span frame tent. After completion, the tent is in the form of Fig.16 shown.

[0046] The folding process of the large-span frame tent is as follows:

[0047] When the large-span frame tent needs to be folded, the integrated bracket module is first transferred to the bottom of the tent, and the jacking device is raised to the middle frame part of the tent and engaged with the middle frame.

[0048] When receiving the folding command, the first step is to use the wire rope to wrap around the outer circle of the tent, wrap around it once and fold it in the middle of the tent, then tighten the wire rope to make the 8 legs fold to the middle, and use cable ties to fix the legs and the flip frame. After completion, the tent will be in the shape of Fig.15 shown.

[0049] The second step is to take the frame with outriggers connected to the middle frame as the center, and fold the frame with outriggers and the frame without outriggers into a semicircle along the middle frame on both sides, and finally fold them to one side of the middle frame. After completion, the tent will look like this Fig.14 shown.

[0050] The third step is to pull out the positioning pins connecting the lower part of the legs to the upper part, push the lower part of the legs back to the specified position and insert the positioning pins to position them. After completion, the tent will look like this Fig.13 shown.

[0051] The fourth step is to loosen the interlocking buckle between the fixed frame and the lower chord of the flip frame, and then flip the flip frame with the outrigger frame and the flip frame without the outrigger frame 180° to the unfolded position to complete the flip. Fig.12 shown.

[0052] The above process describes the whole process of unfolding and folding the large-span frame tent in cooperation with manual labor. The present invention realizes the rapid unfolding and folding of the large-span frame tent through the application of reasonable mechanism design.

[0053] The advantages of the present invention are that, firstly, compared with the traditional frame tent, the large frame tent that can be quickly deployed and folded has a more compact structure and a smaller volume and weight, which makes it more suitable for the scenario of transportation and installation using a containerized bracket, avoiding the problem of occupying a large space causing transportation difficulties and affecting the stability of the vehicle. Secondly, the method of combining a fixed frame and a flip frame effectively increases the actual use area; at the same time, the fixed frame and the flip frame are designed using the truss design principle, which can provide excellent load-bearing performance and stability, and can withstand large wind loads and snow loads. By standardizing the deployment and folding process, the tent can be deployed and folded more easily, improving the efficiency and safety of deployment and withdrawal.

[0054] 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 modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
