[0022] Please refer to Figure 1-Figure 6The utility model provides a technical solution: a door structure of a spherical tent, comprising a tent body 1, a crossbeam 2 and a door frame 3, two door bodies 9 are installed on the outer surface of the door frame 3, the top of the door frame 3 is convex, the top inner surface of the door frame 3 is rotatably connected with a rotating drum, the outer surface of the rotating drum is fixedly sleeved with a gear 4, the outer surface of the gear 4 is movably meshed with two racks 5, the outer surfaces of the two racks 5 are fixedly connected with a mounting plate 6, two mounting grooves 7 are provided inside the crossbeam 2, the bottom outer surface of the rotating drum is fixedly connected with a crank 8, the bottom outer surface of the crank 8 is provided with a circular limiting groove 18, and the edge of the circular limiting groove 18 is provided with a plurality of strip limiting grooves 19, the top outer surface of the door frame 3 is provided with a sealing plate, the top of the sealing plate A limit rod 20 is fixedly connected to the outer surface, and two limit strips 21 are fixedly connected to the outer surface of the limit rod 20. The convex shape of the door frame 3 is inserted into the cross beam 2, and the crank 8 is turned. The crank 8 drives the gear 4 to rotate, and the gear 4 makes the two racks 5 move away from each other, so that the mounting plate 6 is inserted into the mounting groove 7, thereby fixing the door frame 3, and installing the sealing plate so that the limit rod 20 is inserted into the circular limit groove 18, and the strip limit groove 19 is inserted into the limit rod 20 to prevent the crank 8 from rotating, and then the door body 9 is installed. When disassembling, the crank 8 is turned in the opposite direction to disengage the mounting plate 6 from the mounting groove 7, which is convenient for installing and disassembling the door frame 3, thereby facilitating the installation and disassembly of the door body 9.

[0023] Transparent windows 10 are provided on the outer surfaces of the two door bodies 9. The outer surfaces of the two door bodies 9 located on the inner side of the tent body 1 are fixedly connected to two first fixed blocks 11. The outer surfaces of the two fixed blocks are rotatably connected to a winding shaft 12. A shielding curtain 13 is wound around the outer surface of the winding shaft 12. A counterweight rod 14 is fixedly connected to the bottom outer surface of the shielding curtain 13. The winding shaft 12 rolls up the shielding curtain 13, so that the transparent window 10 is in a transparent state, thereby increasing the light transmittance.

[0024] Two second fixing blocks 15 are fixedly connected to the outer surfaces of the two door bodies 9 located below the inner side of the transparent window 10, and two springs 16 are fixedly connected to the inner surfaces of both ends of the counterweight rod 14. The other ends of the two springs 16 are fixedly connected to the insertion rod 17. The outer surfaces of the two second fixing blocks 15 are provided with slots adapted to the insertion rod 17. The outer surface of the winding shaft 12 is fixedly connected to a coil spring, and the other end of the coil spring is fixedly connected to the inner outer surface of the door body 9. In this embodiment, when the counterweight rod 14 is pulled down, the winding shaft 12 is The reel 12 rotates, and the coil spring is deformed, causing the shielding curtain 13 to be spit out from the reel 12. The rod 17 is then pressed inward to compress the spring 16. When the rod 17 corresponds to the insertion hole of the second fixing block 15, the rod 17 is released. The rod 17 is inserted into the insertion hole under the elastic force of the spring 16, thereby limiting the counterweight rod 14. The shielding curtain 13 blocks the transparent window 10 to protect privacy. When the rod 17 is disengaged from the insertion hole, the coil spring is reset, and the reel 12 rolls up the shielding curtain 13.

[0025] A plurality of strip limit grooves 19 are arranged in a circular array, and two limit strips 21 are arranged symmetrically, and the two limit strips 21 are adapted to the strip limit grooves 19. In this embodiment, when the sealing plate is installed, the limit strip 21 is inserted into the strip limit groove 19, and by setting a pair of strip limit grooves 19, when the crank 8 is rotated, if the strip limit groove 19 is aligned with the limit strip 21, the crank 8 only needs to be slightly rotated to adjust it to align with the limit strip 21.

[0026] The sealing plate is fixedly connected to the top downward outer surface of the door frame 3 by bolts. In this embodiment, the sealing plate is provided to prevent strangers from turning the crank 8, which would cause the door frame 3 to be unstable.

[0027] Two sliding rods are fixedly connected to the inner surface of the door frame 3, and sliders are fixedly connected to the outer surfaces of the two racks 5. The two sliders are slidably connected on the outer surfaces of the two sliding rods respectively. In this embodiment, when the rack 5 moves, the slider slides on the outer surface of the sliding rod, so that the rack 5 can move stably.

[0028] Working principle: When the utility model is in use, the tent body 1 is installed and fixed, and the crossbeam 2 is fixed at the place where the door of the tent body 1 needs to be installed, the convex shape of the door frame 3 is inserted into the crossbeam 2, and the crank 8 is turned. The crank 8 drives the gear 4 to rotate, and the gear 4 makes the two racks 5 move in directions away from each other, so that the mounting plate 6 is inserted into the mounting groove 7, thereby fixing the door frame 3, and the sealing plate is installed, so that the limit rod 20 is inserted into the circular limit groove 18, and the strip limit groove 19 is inserted into the limit rod 20 to prevent the crank 8 from rotating, and then the door body 9 is installed. When disassembling, the crank 8 is turned in the opposite direction to disengage the mounting plate 6 from the mounting groove 7, which is convenient for installing and disassembling the door frame 3, thereby facilitating the installation and disassembly of the door body 9.

[0029] When the door body 9 is in use, the reel 12 reels the shielding curtain 13, making the transparent window 10 in a transparent state and increasing the light transmittance. When the counterweight rod 14 is pulled downward, the reel 12 rotates, and the coil spring is deformed at this time, causing the shielding curtain 13 to be spit out from the reel 12. Then the plug rod 17 is pressed inward to compress the spring 16. When it corresponds to the insertion hole of the second fixing block 15 of the plug rod 17, the plug rod 17 is released. Under the elastic force of the spring 16, the plug rod 17 is inserted into the insertion hole, thereby limiting the counterweight rod 14, and the shielding curtain 13 blocks the transparent window 10 to protect privacy. When the plug rod 17 is disengaged from the insertion hole, the coil spring is reset, and the reel 12 rolls up the shielding curtain 13, so that the transparent window 10 can be blocked as needed to increase privacy, and the light transmittance of the door body 9 can be increased as needed.
