At the same time, a telescopic locking structure is provided on the legs to retract the legs to reduce the overall height when folding, and to lock the legs to support the tent top to a desired height when unfolding.

[0004] According to the above structure, the damage of the existing folding tent mainly occurs on the legs, because after the folding tent is unfolded, the length of the legs needs to be fixed by the telescopic locking structure, which results in the entire weight of the tent being supported entirely by the telescopic locking structure, which results in the telescopic locking structure of the legs being frequently damaged, thus shortening the service life of the folding tent. In addition, during the process of unfolding and erecting the folding tent, in the field with uneven terrain, the stress points of multiple legs are prone to uneven stress, so it is difficult to provide support for the folding tent at the best point, resulting in poor stability of the folding tent.

[0030] The technical solution of the utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 6 As shown, a folding tent provided by an embodiment of the utility model comprises a plurality of pairs of connecting seats, and a plurality of eccentric cross rod groups and a plurality of central cross rod groups connected between the plurality of pairs of connecting seats;

[0032] Each pair of connection sockets includes an outer connection socket and an inner connection socket which are arranged opposite to each other;

[0033] Each eccentric cross rod group includes a first pin and two first connecting rods, the two first connecting rods are arranged crosswise with each other, the first pin is arranged at the intersection of the two first connecting rods and is rotatably connected to the two first connecting rods respectively; the intersection is located at a position biased toward one end of the midpoint of the two first connecting rods, so that the connection line of the four end points of the two first connecting rods is trapezoidal; in the first connecting rod, the end close to the intersection is the proximal end, and the end far from the intersection is the distal end;

[0034] Each central cross rod group includes a second pin and two second connecting rods, the two second connecting rods are arranged crosswise with each other, the second pin is arranged at the intersection of the two second connecting rods and is rotatably connected to the two second connecting rods respectively; the intersection is located at the midpoint of the two second connecting rods, so that the connection line of the four end points of the two second connecting rods is in a rectangular shape;

[0035] When the folding tent is in a fully folded state, the outer connecting seat in each pair of connecting seats is arranged directly above the inner connecting seat. At the same time, the plurality of connecting seats are arranged into five columns along the X-axis direction and arranged into N rows along the Y-axis direction, where N≥2. The depth of the folding tent can be changed by changing the size of N. In the present embodiment, N=4. In the X-axis direction, each two adjacent pairs of connecting seats are connected by an eccentric cross rod group, wherein the two adjacent outer connecting seats are respectively hinged to the distal ends of the two first connecting rods, and the two adjacent inner connecting seats are respectively hinged to the proximal ends of the two first connecting rods; in the Y-axis direction, each two adjacent pairs of connecting seats are connected by a central cross rod group, wherein the two adjacent outer connecting seats are respectively hinged to one end of the two second connecting rods, and the two adjacent inner connecting seats are respectively hinged to the other end of the two second connecting rods.

[0036] Furthermore, in each pair of connecting seats arranged in the second column, the third column and the fourth column in the X-axis direction, a third connecting rod is arranged between the inner connecting seat and the outer connecting seat, one end of the third connecting rod is fixedly connected to the middle part of the inner connecting seat, and the middle part of the outer connecting seat is provided with a plug-in groove matching the third connecting rod; when the folding tent is in a fully unfolded state, the other end of the third connecting rod is plugged into the plug-in groove in the middle part of the outer connecting seat, so that the paired inner connecting seat and the outer connecting seat are relatively installed and fixed.

[0037] For reference, in another embodiment of the present invention not shown in the figure, one end of the third connecting rod can also be fixedly connected to the middle of the outer connecting seat, and a plug-in slot matching the third connecting rod is provided in the middle of the inner connecting seat. Based on this structure, when the folding tent is in a fully unfolded state, the other end of the third connecting rod is plugged into the plug-in slot in the middle of the inner connecting seat, so that the paired inner connecting seat and the outer connecting seat are relatively installed and fixed.

[0038] Specifically, a plurality of hinge grooves are respectively provided on the outer sides of the outer connecting seat and the inner connecting seat, and the end of the first connecting rod or the second connecting rod is hinged in the corresponding hinge groove through a hinge pin to achieve connection with the inner connecting seat or the outer connecting seat.

[0039] Further, in each eccentric cross rod group, the hinge pin at the end of the first connecting rod is parallel to the first pin at the intersection, so that the hinge rotation axis between the first connecting rod and the connecting seat is parallel to the cross rotation axis between the two first connecting rods;

[0040] In each central cross rod group, the hinge pin at the end of the second connecting rod is parallel to the second pin at the intersection, so that the hinge rotation axis between the second connecting rod and the connecting seat is parallel to the cross rotation axis between the two second connecting rods.

[0041] Furthermore, the lengths of the first connecting rod and the second connecting rod are equal, so that when the folding tent of this embodiment is in a fully folded state, the distances between all the inner connecting seats and the outer connecting seats remain consistent.

[0042] In this embodiment, the lengths of the first connecting rod and the second connecting rod are 177 cm; the length of the third connecting rod is 14.4 cm. In the first connecting rod, the intersection is located 3 cm from the midpoint of the first connecting rod to one end.

[0043] Refer to the order in which Figures 1 to 6 The complete unfolding process of the folding tent provided in this embodiment is as follows:

[0044] exist Figure 1In the fully folded state shown, each inner connection seat and outer connection seat are pulled outward along the X-axis direction and the Y-axis direction. Since the two first connecting rods in the eccentric cross rod group are connected in an eccentric cross manner, and in the X-axis direction, two adjacent inner connection seats are connected to the proximal ends of the two first connecting rods, and two adjacent outer connection seats are connected to the distal ends of the two first connecting rods, when the folding tent is unfolded along the X-axis direction, the increase in the distance between the two adjacent inner connection seats is slightly lower than the distance between the two adjacent outer connection seats, resulting in the shape formed by the two adjacent pairs of connection seats being a trapezoid with a long upper base and a short lower base. Figures 2 to 5 As shown, as the folding tent is gradually unfolded along the X-axis direction, the length difference between the spacing between adjacent inner connecting seats and the spacing between adjacent outer connecting seats in the X-axis direction becomes larger and larger, and the trapezoidal deformation trend with a long upper base and a short lower base becomes more and more obvious, making the overall shape of the folding tent on the XOZ plane more and more close to an arch.

[0045] At the same time, because the two second connecting rods in the central cross rod group are connected in a central cross manner, when the folding tent is unfolded along the Y-axis direction, the shape enclosed by two adjacent pairs of connecting seats in the Y-axis direction is always rectangular. Figures 2 to 5 As shown, as the folding tent is gradually unfolded along the Y-axis direction, the distance between two adjacent pairs of connecting seats in the Y-axis direction is enlarged, but this can only cause the depth of the folding tent in the Y-axis direction to increase, and does not cause deformation in other directions.

[0046] Finally Figure 6 As shown, when the folding tent is in a fully expanded state, the whole presents an arched channel extending along the Y-axis direction; at this time, the other end of the third connecting rod located in the middle of the inner connecting seat of the middle three columns (the second column, the third column, and the fourth column) is plugged and fixed with the corresponding outer connecting seat, so that the folding tent can be fixed in the fully expanded state, and the overall stability and deformation resistance are stronger.

[0047] On the contrary, according to Figure 6 to Figure 1 The folding tent can be completely folded and stored by operating the folding tent in the following order. Figure 1 As shown, since the lengths of the first connecting rod and the second connecting rod are equal, when in a fully folded state, the distances between all the inner connecting seats and the outer connecting seats are equal, and the entire folding tent is in a cube shape after being fully folded, and its structure is more compact and occupies less space.

[0048] The utility model provides a folding tent, which, through a clever structural design, makes the overall shape of the tent after being fully unfolded into an arched channel shape, which has stronger support and stability, and the overall structure is more solid and has a longer service life. At the same time, the folding tent of the utility model has a more compact structure after being fully folded, occupies less space, and is easy to carry and store.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
