The hook can be inserted downward from the upper end of the base 2, or inserted upward from the lower end of the base 2, or inserted relatively from both sides of the base 2.

[0029] The bottom of the base 2 is provided with a positioning connection groove 7, and the top of the caster bracket 3 is provided with a positioning connection block 8 corresponding to the positioning connection groove 7. The positioning connection groove 7 and the positioning connection block 8 enable the caster bracket 3 and the base 2 to achieve rapid positioning, installation and stable connection. As a specific implementation, the positioning connection groove 7 is arranged in a T-shape, the base 2 is arranged in a right-angled triangle, the positioning connection block 8 is arranged in a right-angled triangle, the inner side of the positioning connection block 8 is provided with a right-angled triangle connection groove 9, and the bottom of the base 2 is provided with a right-angled triangle connection block 10 corresponding to the right-angled triangle connection groove 9, so that the caster bracket 3 can be installed on one side or the other side of the right angle of the base 2, and can be installed according to the actual use direction of the caster 4, which is more convenient to use. Of course, the shape of the positioning connection groove 7 and the positioning connection block 8 can be square or other shapes.

[0030] The caster bracket is provided with a support plate 12, one side of the support plate 12 is subjected to force from the base 2 or the tent support tube 1, and the roller 4 is provided on the other side of the support plate 12. The caster bracket 3 supports the base 2 more stably, and dragging or pushing the folded tent is more stable, thus avoiding large deformation of the caster bracket 3 due to force.

[0031] As a specific implementation, a connecting sleeve 11 is installed on the outer side of the bottom of the tent support tube 1, and the abutment plate 12 abuts against the connecting sleeve 11, increasing the force-bearing area of ​​the caster bracket 3 and the tent support tube 1, making the caster bracket 3 support the base 2 more stably, and dragging or pushing the folded tent more smoothly, avoiding the caster bracket 3 from being deformed or even broken by force. As another specific implementation, a force-bearing plate that abuts against the abutment plate 12 is provided on the outer edge of the base 2, and the abutment plate 12 abuts against the force-bearing plate, thereby improving the stability of the caster bracket 3 in use.

[0032] The caster bracket 3 is provided with a mounting protection plate 13 for mounting the roller 4. The mounting protection plate 13 is provided with a screw mounting hole 14. The roller 4 is mounted on the mounting protection plate 13 by means of a screw 15 and a locking nut 16, so as to facilitate quick and stable mounting of the roller 4. The shape of the mounting protection plate 13 is adapted to the side of the roller 4, so as to effectively protect the roller 4 from being touched by the outside.

[0033] The top of the base 2 is provided with a sleeve column 17 for the tent support tube 1 to be installed, so that the base 2 can be stably installed on the tent support tube 1, and the plug-in column 5 is plugged into the inner side of the sleeve column 17, so that the connection of the plug-in column 5 is more stable and the installation of the caster bracket 3 is more stable.

[0034] The upper part of the sleeve column 17 is gradually enlarged from top to bottom, which is beneficial to the sleeve column 17 to stabilize the tent support pipe 1, the force connection is gradually increased, and the connection is stable. The upper part of the sleeve column 17 is respectively provided with a connecting groove 18 and a connecting hole 19. The connecting hole 19 allows the sleeve column 17 to be connected to the tent support pipe 1 through a connecting screw or a connecting nail or a positioning nail, and the connection is more stable. The connecting groove 18 is beneficial to the guided installation of the sleeve column 17, so that the installation of the base 2 is more stable.

[0035] A reinforcing rib 20 is provided at the bottom of the base 2 to save production costs and improve the structural strength of the base 2. The base 2 is provided with a bolt mounting hole 21 to facilitate the base 2 to be fixed to the ground by bolts.

[0036] The bottom surface of the base 2 is flush with the bottom surface of the caster bracket 3, and the bottom surface of the roller 4 is flush with the bottom surface of the caster bracket 3. When in use, the base 2, the caster bracket 3 and the roller 4 are all in contact with the ground, which improves the support stability of the tent and has a good use effect.

[0037] The base 2 and the caster bracket 3 are both made of plastic parts, which have low manufacturing cost, are easy to install, and are durable and stable.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
