As defined herein, the terms "inner" and "outer" are used with reference to the vertical centerline of the tent, and are used with reference to being closer to the vertical centerline of the tent as being inner and vice versa. The inner ends of the four inner poles 21 of the four pole assemblies 2 are rotatably connected to a center lock 4 by pivots so that the four pole assemblies 2 constitute a cross-shaped structure extending along the diagonal of the tent upper frame toward the four top corners of the tent, respectively, and are rotatable relative to each other.

The clamping part 221 has a clamping groove matched with the inner post rod 21, and the inner post rod 21 can be clamped in the clamping groove, so that the tent in the unfolding state is more stable; the slot has an upward notch and the inner post 21 can be disengaged from the slot when rotated without interfering with the folding of the tent. The clamping member 221 is an S-shaped tube fixedly disposed on the inner end of the outer top rod 22, and the inner top rod 21 is clamped in a clamping groove of the S-shaped tube.

Specifically, in the present embodiment, each side bar assembly 3 is composed of three cross brace members 30, wherein the upper end of the first connecting rod 31 is rotatably connected to the upper end of one of the column assemblies 1 or the upper end of the second connecting rod 32 of another cross brace member 30, the lower end of the first connecting rod 31 is rotatably connected to the lower end of the second connecting rod 32 of another cross brace member 30 or the second sliding block 13 of another column assembly 1, the lower end of the second connecting rod 32 is rotatably connected to the second sliding block 13 of one column assembly 1 or the lower end of the first connecting rod 31 of another cross brace member 30, and the upper end of the second connecting rod 32 is rotatably connected to the upper end of the first connecting rod 31 of another cross brace member 30 or the upper end of another column assembly 1.

Referring to fig. 8 to 14, the present embodiment also provides another collapsible tent. The collapsible shelter is substantially the same as the shelter shown in fig. 1 to 7, except that: the cornice rod 23 can be connected to the upper end part of the corresponding upright post component 1 in a rotatable and sliding way along the length direction; and a rotation limiting mechanism 26 for limiting the rotation angle is arranged at the rotation connection position of the cornice rod 23 and the second supporting rod 25.

As shown in fig. 8 and 9, the cornice lever 23 is slidably provided with a first sliding sleeve 231, and the first sliding sleeve 231 is rotatably connected to the upper end of the upright post assembly 1 through a pivot. And the upper end of the upright post component 1 is provided with a containing groove 14 matched with the cornice rod 23, when the tent is in an unfolding state, the cornice rod 23 is clamped in the containing groove 14, so that the stability is improved.

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

As shown in fig. 6 and 7 or fig. 12 to 14, when the tent is folded, the central lock 4 is unlocked first, and the central lock 4 may adopt a structure known in the prior art, which is not described herein; the upright post lower section 12 of the upright post component 1 is accommodated in the upright post upper section 11; the second slide block 51 on the upright post component 1 slides downwards, the first stay bar 24 rotates, the inner end part of the inner ejector rod 21 and the outer end part of the outer ejector rod 22 are closed, and the outer end part of the cornice rod 23 rotates upwards and slides inwards so as to be folded inwards; meanwhile, along with the folding of the top rod component 2, the upright component 1 is also mutually closed, so that the cross brace rods 30 of the side rod component 3 are mutually folded and closed; when the second sliding block 51 moves to the lowest position, the upright post assemblies 1 are mutually closed, the cross brace rod assemblies are mutually closed, and the ejector rod assemblies 2 are mutually closed between the upright post assemblies 1. It can be seen that in the folding process, the cornice rod 23 can be folded together with other rod members, the cornice rod 23 does not need to be folded independently, and the folding operation is convenient.

On the contrary, when the tent is unfolded, the second sliding block 51 is pushed upwards, and the inner top bar 21, the outer top bar 22 and the cornice bar 23 of each top bar assembly 2 are unfolded relatively under the action of the first support bar 24 and the second support bar 25; the upright post component 1 and the side bar component 3 are then expanded to the periphery; after the tent is unfolded, the tent is stabilized in the unfolded state as shown in fig. 1 by the central lock. In the unfolding process, the cornice rod 23 can be unfolded together with other rod pieces, the cornice rod 23 does not need to be unfolded independently, and the unfolding is convenient.

Fig. 15-17 illustrate another rotation limiting mechanism 26. Referring to fig. 15 to 17, the rotation limiting mechanism 26 includes a pivot seat 261, and the cornice lever 23 and the second supporting rod 25 are both connected to the pivot seat 261, and one of the components is pivoted to the pivot seat 261 so as to be capable of rotating relatively. Specifically, the cornice lever 23 is connected to a first end of the pivot base 261 by one rivet 263, and the second stay 25 is pivoted to a second end of the pivot base 261 by another rivet 263. The first end of the pivot 261 is formed with an insertion hole matching with the outer circumference of the cornice lever 23, and the cornice lever 23 is inserted into the insertion hole and riveted by a rivet 263. The second end of the pivot seat 261 is opened with a slot, the second stay 25 is inserted into the slot and riveted by the rivet 263, and the upper end of the slot is opened, so as to allow the second stay 25 to rotate relative to the pivot seat 261, when the second stay 25 abuts against the lower slot wall 2612 of the slot, the second stay 25 cannot rotate any further, as shown in fig. 17, the tent is in the unfolding state.
