[0003] For example, a Chinese patent document discloses a central locking device for a folding tent (application number: 201920586891.1), which includes a top plate seat, a lower plate seat, and a locking rod connecting the top plate seat and the lower plate seat. The lower plate seat includes a lower plate seat body and a lower plate seat cover. A wrench is installed under the lower plate seat body. The wrench and the locking rod are provided with a locking mechanism that cooperates with each other. The locking mechanism includes a slot and a spring seat respectively arranged on both sides of the wrench, a spring arranged on the spring seat, and a spring receiving cavity correspondingly arranged on the lower plate seat body, and an annular groove arranged at the lower end of the locking rod. One end of the spring is sleeved on the spring seat, and the other end of the spring is arranged in the spring receiving cavity.

[0004] The above-mentioned central locking device for folding tents has the following shortcomings during use: the wrench is pressed against the bottom wall of the annular groove at the lower end of the locking rod under the elastic force of the spring, thereby locking the locking rod. However, after the spring has been used for a period of time, the elastic force of the spring will gradually weaken as the use progresses, thereby affecting the reliability of the wrench locking the locking rod. Summary of the invention

[0008] The support rod locking device of the folding tent relies on the two elastic clamping arms of the hard elastic clamping piece to clamp and position the support rod, and has good clamping stability and clamping reliability. When unlocking, the user only needs to press a button to simultaneously open the two elastic clamping arms of the elastic clamping piece to remove the support rod, and the operation is convenient. After the button is removed, the two elastic clamping arms of the elastic clamping piece can be reset, thereby improving the reliability of the support rod locking device of the folding tent.

[0009] In addition, the folding tent support rod locking device involves fewer parts, has a simple structure, and has low manufacturing and use costs, which is conducive to promotion and application.

[0010] In the above-mentioned folding tent support pole locking device, the elastic clamp is U-shaped, the closed end of the elastic clamp is connected to the lower plate seat, and the open end of the elastic clamp is flared and arranged toward the button. The U-shaped elastic clamp is convenient for processing and manufacturing on the one hand, and has good structural strength on the other hand, which is conducive to the opening and closing of the two elastic clamp arms of the elastic clamp.

[0011] In the above-mentioned folding tent support pole locking device, the lower plate seat has adjacently arranged positioning blocks and positioning holes for the lower end of the support pole to be inserted, the two elastic clamping arms of the elastic clamp abut against the edge of the positioning hole, the top of the positioning block has an embedding groove, the closed end of the elastic clamp is clamped in the embedding groove, and the portion of the positioning block between the positioning hole and the embedding groove extends into the elastic clamp. By clamping the closed end of the elastic clamp in the embedding groove, and at the same time extending the portion of the positioning block between the positioning hole and the embedding groove into the elastic clamp, and the two elastic clamping arms of the elastic clamp abut against the edge of the positioning hole, the reliability of the connection of the elastic clamp can be improved on the one hand, and the opening and closing action of the two elastic clamping arms of the elastic clamp can not be affected on the other hand, and the edge of the positioning hole can play a supporting role when the two elastic clamping arms are opened and closed, thereby improving the reliability of the folding tent support pole locking device.

[0014] In the above-mentioned folding tent support pole locking device, the fixing part is provided with a mounting hole, and a spring is arranged in the mounting hole, one end of the spring abuts against the bottom wall of the mounting hole, and the other end abuts against the side wall of the mounting slot facing the button. By arranging the spring, when the external force is removed, the button can automatically reset under the elastic force of the spring, which is more convenient to use. At the same time, when the user presses the button, the spring can provide a blocking force, and the pressing operation is better.

[0015] In the above-mentioned folding tent support pole locking device, the two elastic clamping arms of the elastic clamping member abut against the top edge of the mounting groove, and the top edge of the mounting groove has two limiting parts, and the two limiting parts are respectively located on the outside of the two elastic clamping arms. The top edge of the mounting groove can form a support limit for the two elastic clamping arms, thereby improving the reliability of the clamping and positioning of the two elastic clamping arms. When the two elastic clamping arms are opened by the button, the two limiting parts can limit the maximum angle of the elastic clamping arms, avoiding irreversible deformation of the two elastic clamping arms due to excessive opening angles, thereby improving the reliability of the clamping and positioning of the two elastic clamping arms.

[0016] In the above-mentioned folding tent support pole locking device, the lower disc seat includes a detachably connected seat body and a seat cover, the seat cover has a docking hole opposite to the positioning hole up and down and a limit pressure block located above the elastic clip, and the installation groove, positioning hole and positioning block are all arranged on the seat body. The seat body and the seat cover are preferably detachably connected by bolts, and the detachably connected seat body and seat cover facilitate the disassembly and replacement of the elastic clip, button and spring, making the folding tent support pole locking device more durable. In addition, the installation groove, positioning hole and positioning block are all arranged on the seat body, and the structure is more reasonable. The docking hole on the seat cover is conducive to the connection between the support pole and the lower disc seat on the one hand, and the hole wall of the docking hole can limit the support pole on the other hand, and the limit pressure block can limit the upward movement of the elastic clip, so that the button can better open the two elastic clamping arms of the elastic clip, thereby improving the reliability of the folding tent support pole locking device.

[0017] In the above-mentioned folding tent support pole locking device, the lower end of the support pole has an annular groove, the lower end surface of the support pole is arc-shaped, and the two elastic clamping arms of the elastic clamping member are both located in the annular groove. The two side walls on the upper and lower sides of the annular groove can respectively form upper and lower limit positions for the two elastic clamping arms located in the annular groove, thereby further improving the reliability of the existing folding tent support pole locking device. The lower end surface of the support pole is arc-shaped, which facilitates the support pole to pass downward through the elastic clamping member until the two elastic clamping arms are clamped in the annular groove.

[0018] Compared with the prior art, the advantages of the support pole locking device of the folding tent are: the support pole locking device of the folding tent relies on the two elastic clamping arms of the hard elastic card to clamp and position the support pole, and has good clamping stability and clamping reliability. When unlocking, the user only needs to press a button to simultaneously open the two elastic clamping arms of the elastic card to remove the support pole, which is easy to operate. In addition, the support pole locking device of the folding tent involves fewer parts, a simple structure, and low manufacturing and use costs, which is conducive to popularization and application.
