Background

The tent has various structural forms, and the tent for outdoor sunshade can be generally divided into a fixed tent and a folding tent. The fixed tent is enlarged in size, is usually suitable for long-term fixed placement and is not suitable for being carried outdoors. The folding tent is also named as an advertisement tent and a sunshade, and can be used for holding outdoor exhibition and product promotion and publicity, celebration evening, exhibition and sales, travel and leisure, field operation, large gear and the like. However, the conventional folding tent is usually provided with the lock catches on the leg rods, and needs to be operated by a plurality of people to complete folding, storage or unfolding, so that the operation is cumbersome.

Therefore, many folding tents with central unlocking structures are developed nowadays, for example, the publication number is CN204024196U, and a tent with a single-point lock is disclosed, which comprises leg tubes, cross tubes, a central tube and a slide block, wherein the cross tubes are composed of outer cross tubes and inner cross tubes, the leg tubes are located at the outer side of the central tube, two adjacent leg tubes are hinged to each other through X-shaped outer cross tubes, and the leg tubes and the central tube are hinged to each other through X-shaped inner cross tubes; the central tube is internally provided with a single-point locking structure. The single-point locking structure comprises a first sliding block, a movable pin connecting block, a first movable pin, a connecting rod, a button block, a first central bottom cap and a first central top cap, and a locking hole is formed in the central pipe; a button block is arranged in the lower end pipe of the central pipe, the upper end of the button block is connected with one end provided with a connecting rod, the other end of the connecting rod is connected with a movable pin connecting block, a chute is arranged on the movable pin connecting block, and the other end of the connecting rod is embedded in the chute of the movable pin connecting block through a movable bolt and is connected with the movable pin connecting block; the upper end of the movable pin connecting block is connected with a movable pin I; the outer side of the central tube is sleeved with a first sliding block, a round hole is formed in the first sliding block, and a first movable pin is embedded in the round hole of the first sliding block through a lock catch hole of the central tube. However, such a single-point lock structure is relatively complex, and it needs to be integrated and set up in the center tube, resulting in higher product processing cost, and in the long-term use process, the loss easily appears in individual spare part, resulting in the unable normal use of product, influences performance.
