Detailed Implementation
[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0017] like Figures 1-4 As shown, a linkage hinge includes a first fixed rod 1, a second fixed rod 2, a first support member 3, and a second support member 4. One end of the first support member 3 is connected to one end of the first fixed rod 1 via a first pivot 5. The other end of the first support member 3 is connected to a first connecting rod 7 via a second pivot 6. The other end of the first connecting rod 7 is connected to one end of the second fixed rod 3 via a third pivot 8. One end of the second support member 4 is connected to the other end of the second fixed rod 2 via a fourth pivot 9. The other end of the second support member 4 is connected to a second connecting rod 11 via a fifth pivot 10. The other end of the second connecting rod 11 is connected to the other end of the first fixed rod 1 via a sixth pivot 12. The first support member 3 and the second support member 4 are cross-connected via a seventh pivot 13. Both the first fixed rod 1 and the second fixed rod 2 are provided with storage slots 14. The first support member 3, the second support member 4, the first connecting rod 7, and the second connecting rod 11 are all folded and placed between the two storage slots 14.
[0018] The hinge of this invention has a simple structure. Through the cooperative design of the support member and the connecting rod, the hinge can achieve simultaneous rotation, unfolding and lifting, which facilitates the operation and use of the tent. Because the hinge has a certain unfolding height, it can increase the unfolding height of the tent sides and expand the usable space inside the tent. The support member and the connecting rod can be stacked in the storage groove of the fixed rod at the same time, which greatly reduces the folded volume of the hinge, and thus reduces the overall folded volume of the tent.
[0019] Further, the first support 3 and the second support 4 each comprise two support rods, and the two support rods of the first support 3 are located between the two support rods of the second support 4, the first connecting rod 7 is located between the two support rods of the first support 3, and the second connecting rod 11 is located between the two support rods of the second support 4. The above design facilitates the unfolding of the hinge, and when the hinge is folded, the two support rods of the first support 3 and the two connecting rods can be folded between the two support rods of the second support 4, greatly reducing the folding height and thus reducing the overall folding volume of the hinge.
[0020] Further, the first fixed rod 1 is symmetrically provided with a first clamping groove 15, the second fixed rod 2 is symmetrically provided with a second clamping groove 16, and the receiving grooves 14 of the first fixed rod 1 and the second fixed rod 2 are each provided with a connecting hole 17 at intervals, and the side of the receiving groove 14 extends to form a connecting block 18. After the hinge is folded, the first clamping groove 15 and the second clamping groove 16 are symmetrically clamped at the outer end of the seventh rotating shaft 13, and the connecting block 18 is located between the two support rods at the corresponding position. The above design can make the first fixed rod 1 and the second fixed rod 2 clamped at the end position of the seventh rotating shaft 13 when the folding hinge is folded, realize a certain limiting clamping effect, and improve the stability of the hinge folding. The connecting block 18 can comprise a connecting rod and a connecting head, which are used for being connected to the corresponding tent carrier, and the width of the connecting rod is less than the interval between the two support rods at the corresponding folding position, so that the connecting rod can be folded between the two support rods, thereby reducing the folding volume.
[0021] Further, the two support rods of the first support 3 are symmetrically provided with a third clamping groove 19, a fourth clamping groove 20, a fifth clamping groove 21 and a sixth clamping groove 22, and the two support rods of the second support 4 are symmetrically provided with a seventh clamping groove 23 and an eighth clamping groove 24. After the hinge is folded, the fourth clamping groove 20 and the seventh clamping groove 23 are overlapped and clamped on the third rotating shaft 8, the fifth clamping groove 21 and the eighth clamping groove 24 are overlapped and clamped on the sixth rotating shaft 12, the third clamping groove 19 is clamped on the fourth rotating shaft 9, and the sixth clamping groove 22 is clamped on the fifth rotating shaft 10. The above design of the clamping grooves at various positions can be clamped on the rotating shafts when the folding hinge is folded, thereby improving the folding stability of the entire hinge, preventing accidental unfolding and other problems, and improving the use stability and safety of the tent.
[0022] The above is only a preferred embodiment of the present application, and does not limit the implementation and protection scope of the present application. For those skilled in the art, it should be realized that any equivalent replacement and obvious changes made according to the content of the present application can be included in the protection scope of the present application.
