And the upper end of stand subassembly 1 is equipped with and cornices the pole 23 matched with hold groove 14, when the tent is in the state of expanding, cornices the pole 23 card in this hold groove 14, increases the steadiness.

As shown in fig. 10 and 11, the rotation limiting mechanism 26 includes a pivot seat 261 and a pivot head 262 pivoted to each other. The pivot seat 261 has a limiting portion 2611 located below the pivot joint 262, and when the tent is in the unfolded state, the limiting portion 2611 abuts against the pivot joint 262, so as to prevent the cornice lever 23 from continuing to rotate relative to the second supporting lever 25. One of the cornice bar 23 and the second brace 25 is fixedly connected to the pivot base 261 and the other is fixedly connected to the pivot head 262. Further, the center line of the cornice bar 23 and the center line of the second stay bar 25 are located in the same plane.

It can be seen that in the folding process, the cornice lever 23 can be folded together with other rods, and the cornice lever 23 does not need to be folded independently, so that the folding operation is convenient.

Conversely, when the tent is unfolded, the second sliding block 51 is pushed upwards, and under the action of the first supporting rod 24 and the second supporting rod 25, the inner supporting rod 21, the outer supporting rod 22 and the cornice rod 23 of each supporting rod assembly 2 are unfolded relatively; the upright post component 1 and the side rod component 3 are then spread towards the periphery; after the tent is unfolded, the tent is stabilized in the unfolded state as shown in fig. 1 by the locking of the center lock. In the unfolding process, the cornice rod 23 can be unfolded along with other rods, the cornice rod 23 does not need to be unfolded independently, and the unfolding is convenient.

Fig. 15 to 17 show a further rotation limiting mechanism 26. Referring to fig. 15 to 17, the rotation limiting mechanism 26 includes a pivot seat 261, the cornice lever 23 and the second supporting lever 25 are connected to the pivot seat 261, and one of the components is pivotally connected to the pivot seat 261 so as to be capable of relatively rotating. Specifically, the cornice 23 is connected to the first end of the pivot seat 261 by a rivet 263, and the second brace 25 is pivoted to the second end of the pivot seat 261 by another rivet 263. The first end of the pivot seat 261 begins with a socket matching the contour of the periphery of the cornice lever 23, into which the cornice lever 23 is inserted and riveted by means of rivets 263. The second end of the pivot seat 261 is provided with a slot, the second stay bar 25 is inserted into the slot and riveted by the rivet 263, and the upper end of the slot is opened, so that the second stay bar 25 can be allowed to rotate relative to the pivot seat 261, and when the second stay bar 25 abuts against the lower side wall 2612 of the slot, the second stay bar 25 cannot rotate further, as shown in fig. 17, and the tent is in the unfolded state.
