Description

Technical Field

[0001] This utility model belongs to the field of outdoor tent technology, and more specifically, it relates to a dome tent. Background Technology

[0002] With societal development and the diversified demands for efficient work, there is a need for some large equipment and facilities to be temporarily stored at outdoor sites for rapid deployment. This is where buildings or tents that provide temporary sites or spaces come in, protecting them from the effects of severe weather.

[0003] Currently, existing outdoor inflatable tents have the following disadvantages when in use: 1. The structural strength of existing outdoor inflatable tents is easily affected by air pressure, requiring continuous air replenishment to maintain structural strength, which is cumbersome to operate; 2. The door position restricts the direction and angle of equipment passage, resulting in poor equipment adaptability; 3. Building traditional reinforced concrete or steel structure buildings has the disadvantages of long raw material transportation time, high structural difficulty, and long construction period, and cannot meet the requirements of mobility and portability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a dome tent.

[0005] To achieve the above objectives, this utility model employs the following technical solution: A dome-shaped tent includes a tent fabric and two sets of opening and closing mechanisms. Two or more frame members are installed between the two sets of opening and closing mechanisms. The tent fabric is attached to the frame members by straps. Each opening and closing mechanism includes a drive mechanism, a clutch mechanism, and side posts. The clutch mechanism and side posts are both mounted on the drive mechanism, and the clutch mechanism is connected to the side posts. Two symmetrical opening and closing mechanisms are arranged at both ends of several semi-circular frame members. Connectors at both ends of the frame members are connected to the side posts on the opening and closing mechanisms and fixedly assembled with pins to form a dome-shaped frame structure. The dome-shaped frame structure is covered with a tent fabric, which is fixedly assembled to the frame members by straps. The tent uses a modular structure for assembly, packaging, and storage.

[0006] Preferably, the drive mechanism includes a base, on which a drive motor and a drive shaft are mounted. The drive motor is connected to the drive shaft via a coupling, and external gears are mounted at both ends of the drive shaft.

[0007] Preferably, the clutch mechanism includes a lever, a U-shaped frame hinged to the end of the lever, a connecting rod hinged to the middle of the lever, a slide rail, a slide plate slidably connected to the slide rail, an internal gear mounting bracket mounted above the slide plate, and an internal gear mounted on the internal gear mounting bracket. The two ends of the connecting rod are mounted on the slide plate, and the internal gear and the external gear are fitted together.

[0008] Preferably, the side post includes one or more connecting side posts and external gears II mounted on both sides of the connecting side post. The one or more connecting side posts are sequentially arranged and mounted on the drive shaft. The external gears II are fitted with internal gears, and the ends of the connecting side posts are connected to the frame through connectors and pins. The drive mechanism drives the external gears II of the right side post and the left side post to rotate by alternately engaging and disengaging with the internal gears on both sides of the clutch mechanism through the external gears I at both ends of the drive shaft.

[0009] Preferably, the skeleton includes N rods, which are connected end to end in sequence by connectors and pins, and the two ends of the first and last rods are connected to the connecting side posts on the side posts by connectors and pins, respectively, where N is a positive integer ≥2.

[0010] Preferably, the skeleton is an arched structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The dome structure of the dome tent gives it good wind resistance. While ensuring structural strength, it does not require continuous air replenishment, has stable performance, and is easy to operate. 2. The modular structure allows for assembly, packaging, and storage, and can be repeatedly disassembled, saving time and effort in loading and transportation. It can be temporarily set up, dismantled, and relocated as needed. 3. The opening and closing mechanism can open and close the tent at a large angle in both directions, making the equipment highly adaptable; In summary, this utility model is highly adaptable, has stable structural strength, is easy to operate, and is convenient and quick to assemble and relocate.

[0014] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0015] Example 1: like Figure 1-2 As shown, a dome-shaped tent includes a tent fabric 3 and two sets of opening and closing mechanisms 1. Two or more frame members 2 are installed between the two sets of opening and closing mechanisms 1. The tent fabric 3 is attached to the frame members 2 by straps. Each opening and closing mechanism 1 includes a drive mechanism 11, a clutch mechanism 12, and side posts 13. The clutch mechanism 12 and the side posts 13 are both mounted on the drive mechanism 11, and the clutch mechanism 12 is connected to the side posts 13. Two symmetrical opening and closing mechanisms 1 are arranged at both ends of several semi-circular frame members 2. Connectors 21 at both ends of the frame members 2 are connected to the side posts 13 on the opening and closing mechanisms 1 and fixedly assembled with pins 23 to form a dome-shaped frame structure. The dome-shaped frame structure is covered with the tent fabric 3, which is fixedly assembled to the frame members 2 by straps. A modular structure is used for assembly, packing, and storage. Specifically, the frame members 2 are arched structures.

[0016] Example 2: A dome-shaped tent, differing from Embodiment 1 in that, as Figure 3 As shown, the drive mechanism 11 includes a base 114, on which a drive motor 111 and a drive shaft 112 are mounted. The drive motor 111 is connected to the drive shaft 112 via a coupling. External gears 113 are mounted at both ends of the drive shaft 112.

[0017] like Figure 4 As shown, the clutch mechanism 12 includes a lever 121, a U-shaped frame 123 hinged to the end of the lever 121, a connecting rod 124 hinged to the middle of the lever 121, a slide rail 125 mounted on the base 114, a slide plate 126 slidably connected to the slide rail 125, an internal gear mounting bracket 127 mounted above the slide plate 126, and an internal gear 122 mounted on the internal gear mounting bracket 127. The lower end of the U-shaped frame 123 is also mounted on the base 114, and both ends of the connecting rod 124 are mounted on the slide plate 126. The internal gear 122 is fitted with the external gear 113.

[0018] like Figure 5As shown, the side post 13 includes one or more connecting side posts 132 and external gears 131 mounted on both sides of the connecting side post 132. The one or more connecting side posts 132 are sequentially arranged and mounted on the drive shaft 112. The external gears 131 are fitted with internal gears 122, and the ends of the connecting side posts 132 are connected to the frame 2 through connectors 21 and pins 23. The drive mechanism 11 drives the external gears 113 at both ends of the drive shaft 112 to alternately mesh and disengage with the internal gears 122 on both sides of the clutch mechanism 12, thereby driving the external gears 131 of the right side post 13 and the left side post 13 to rotate respectively.

[0019] like Figure 6 As shown, the skeleton 2 includes N rods 22. The N rods 22 are connected end to end in sequence through connectors 21 and pins 23. The two ends of the first and last rods 22 are connected to the connecting side posts 132 on the side posts 13 through connectors 21 and pins 23 respectively. N is a positive integer ≥2.

[0020] The working principle of this utility model is as follows: The assembled dome tent is in the open position, such as... Figure 7 As shown, by manipulating the lever 121 on the clutch mechanism 12 to slide to the right, the lever 121 drives the connecting rod 124, which in turn drives the internal gear mounting bracket 127 and the internal gear 122 on the slide plate 126 to slide to the right. This causes the right-end internal gear 122 on the clutch mechanism 12 to simultaneously mesh with the first external gear 113 on the right end of the drive shaft 112 and the second external gear 131 on the right side column 13, thus disengaging the left-end internal gear 122 on the clutch mechanism 12 from the first external gear 113 on the left end of the drive shaft 112. When the drive mechanism 11 rotates clockwise, the external gear 113 at the right end of the drive shaft 112 drives the external gear 131 on the right side post 13 to rotate via the internal gear 122 at the right end of the clutch mechanism 12. This, in turn, drives the semi-circular frame 2 connected to the right side post 13 to rotate. As the outer tarpaulin 4 unfolds, the tension of the outer tarpaulin 4 drives the adjacent connected side post 132 and the corresponding frame 2 to rotate, and so on, until the right side post 13 and the corresponding frame 2 have rotated 180° and are completely closed. Figure 8As shown, the lever 121 on the clutch mechanism 12 slides to the left, causing the left-end internal gear 122 of the clutch mechanism 12 to simultaneously mesh with the left-end external gear 113 of the drive shaft 112 and the left-end external gear 131 of the left side post 13. This causes the right-end internal gear 122 of the clutch mechanism 12 to disengage from the right-end external gear 113 of the drive shaft 112. The drive mechanism 11 rotates clockwise, and the left-end external gear 113 of the drive shaft 112 drives the left-end external gear 131 of the left side post 13 to rotate through the left-end internal gear 122 of the clutch mechanism 12. This, in turn, drives the frame 2 connected to the left side post 13 to rotate. When the frame 2 rotates to the position of the adjacent side post 13 and the corresponding frame 2, it pushes the adjacent side post 13 and the corresponding semi-circular frame 2 to rotate. This process continues until the left side post 13 and the corresponding semi-circular frame 2 rotate 180° and are fully opened, thus realizing the bidirectional large-angle opening and closing of the dome tent.
