[0034] In existing technologies, the unlocking process of the center lock structure of a folding tent requires the user to rotate the upper and lower rotating slides relative to each other and pull them down to complete the unlocking. This results in the center lock unlocking process requiring the coordinated operation of both hands, while also needing to control the unlocked folding tent frame. The operation process is not simple and is not easy to control.

[0035] Based on the aforementioned problems in the prior art, this utility model provides a center locking device for a folding tent, such as... Figure 1 As shown, the center locking device for a folding tent includes: an upper locking member 100, which includes a locking rod 110; and a lower locking member 200, which has a locking hole 230 at its center that is adapted to the locking rod 110.

When the first latch 240 and the second latch 250 are pressed, the first latch 240 and the second latch 250 slide relative to each other to disengage the locking rod 110 from the locking hole 230.

[0036] The utility model discloses a first locking buckle 240 and a second locking buckle 250 are set in the lower locking piece 200 and can slide relatively, so that the first locking buckle 240 and the second locking buckle 250 can be hooked to the locking rod 110 through elastic connection, thereby realizing the locking of the position of the locking rod 110.

[0037] In the above embodiment, as shown in Figure 1 and Figure 2 The utility model discloses a center lock device for folding tent, which comprises an upper locking piece 100 and a lower locking piece 200, as shown in Figure 5 The upper locking piece 100 and the lower locking piece 200 are respectively used to connect with the framework of the folding tent, and when the positions of the upper locking piece 100 and the lower locking piece 200 are locked, the relative angle between the framework structures is locked, so that stable support for the folding tent can be formed, and when the upper locking piece 100 and the lower locking piece 200 are unlocked, the relative angle between the framework structures is unlocked, so that the folding effect through the pivot structure between the framework can be realized.

[0038] Specifically, the upper locking piece 100 comprises a locking rod 110, which is a main structure for locking with the lower locking piece 200, and a lock hole 230 adapted to the locking rod 110 is arranged at the center position of the lower locking piece 200, when the upper locking piece 100 and the lower locking piece 200 are locked, the user inserts the locking rod 110 into the predetermined position in the lock hole 230, and the first locking buckle 240 and the second locking buckle 250 arranged through elastic connection are hooked to form clamping, thereby realizing the locking of the upper locking piece 100 and the lower locking piece 200. This design not only simplifies the unlocking process of the traditional center lock of the folding tent, but also improves the convenience and safety of operation. When unlocking, the user only needs to operate with one hand, and pinches the first locking buckle 240 and the second locking buckle 250, so that the locking rod 110 can be easily released, and unlocking is realized. At the same time, the other hand can freely control the framework of the folding tent, avoiding the inconvenience and safety hazards caused by operating the center lock with both hands.

[0039] Based on the above embodiment, in one embodiment of the utility model, as shown in Figure 1 and Figure 2As shown, the lower locking member 200 is specifically composed of a mounting disc 210 and a base 220, wherein the mounting disc 210 is used for connecting with the partial framework of the folding tent and limiting the first and second lockers 240 and 250 (to be described below in detail), and the base 220 is used for mounting the first and second lockers 240 and 250, and the end of the lock rod 110 is provided with a clamping portion 111, the cross-sectional diameter of which is larger than that of other parts of the lock rod 110, so as to achieve the effect of being clamped and limited by the first and second lockers 240 and 250; in actual arrangement, the lock hole 230 penetrates through the mounting disc 210 and is partially inserted into the base 220, when the user inserts the lock rod 110 into the lock hole 230, the lock rod 110 is inserted into the lock hole 230 of the mounting disc 210 and into the lock hole 230 of the base 220, at this time, since the first and second lockers 240 and 250 are arranged on the base 220, the locking of the clamping portion 111 on the lock rod 110 can be formed under the cooperation of elastic connection and structural shape.

[0040] Further, in order to ensure that the first and second lockers 240 and 250 can stably and smoothly slide on the base 220, the first and second sliding grooves 221 and 222 are oppositely arranged on the base 220, correspondingly, the first locker 240 includes a first sliding tenon 241 which is embeddedly and slidingly arranged in the first sliding groove 221, and the second locker 250 includes a second sliding tenon 251 which is embeddedly and slidingly arranged in the second sliding groove 222, such design not only enhances the stability of the sliding of the first and second lockers 240 and 250, but also helps to maintain the relative position between them, so as to ensure the reliability of the locking and unlocking process.

[0041] Correspondingly, in order to realize the elastic connection of the first and second lockers 240 and 250, the first and second sliding grooves 221 and 222 are oppositely arranged on the base 220, and the first and second lockers 240 and 250 are respectively arranged in the first and second sliding grooves 221 and 222, and the first and second sliding tenons 241 and 251 are respectively embeddedly and slidingly arranged in the first and second sliding grooves 221 and 222. Figure 1 and Figure 4As shown, a through structure is arranged on the base 220 at a position corresponding to the first sliding groove 221 and the second sliding groove 222, the through structure is in the form of a circular hole and communicates the first sliding groove 221 and the second sliding groove 222, meanwhile, the through structure is below the lock hole 230 on the base 220 and is arranged in isolation with the lock hole 230, a compression spring 260 is sleeved in the through structure, one end of the compression spring 260 is connected with the first lock catch 240, and the other end of the compression spring 260 is connected with the second lock catch 250, under the action of the compression spring 260, the first lock catch 240 and the second lock catch 250 can always maintain a certain elastic force, so that the first lock catch 240 and the second lock catch 250 hooked on the lock rod 110 tend to move in opposite directions, thereby ensuring the stability of the locking. When unlocking is needed, the user only needs to pinch the first lock catch 240 and the second lock catch 250 with one hand, so that they overcome the elastic force of the compression spring 260 and move close to each other, at this time, the hooking structure of the first lock catch 240 and the second lock catch 250 moves away from the lock rod 110, thereby releasing the lock rod 110 and achieving unlocking. This design not only simplifies the unlocking process, but also improves the convenience and safety of operation.

[0042] In another embodiment of the present application, as shown in Figure 1 and Figure 3 In order to facilitate user operation, the first lock catch 240 and the second lock catch 250 respectively include a pressing plate 270, and correspondingly, a position corresponding to the first sliding groove 221 and the second sliding groove 222 on the base 220 is provided with a displacement slot 223, and the pressing plate 270 is embedded and slidingly arranged in the displacement slot 223, so that when the user pinches the first lock catch 240 and the second lock catch 250, the fingers can be comfortably placed on the pressing plate 270, increasing the convenience and comfort of operation. Meanwhile, the existence of the pressing plate 270 can also prevent the first lock catch 240 and the second lock catch 250 from being separated from the sliding groove during sliding to a certain extent, further improving the stability and reliability of the structure, in addition, the displacement slot 223 provides an operation space when the first lock catch 240 and the second lock catch 250 compress the compression spring 260, and limits the distance that the first lock catch 240 and the second lock catch 250 can be operated, ensuring the stability of the structure while improving the foolproofness of user operation.

[0043] Further, as shown in Figure 1As shown, the structure for limiting the lock rod 110 is the hook body 280, and the hook body 280 is arranged on the pressing plate 270 of the first lock catch 240 and the second lock catch 250 respectively, the shape of the hook body 280 is L-shaped, the bending position of the hook body 280 corresponds to the lock rod 110, and the hook bodies 280 on the first lock catch 240 and the second lock catch 250 are centrally symmetrically arranged with respect to the center point of the lock hole 230, and under the elastic action of the compression spring 260, the first lock catch 240 and the second lock catch 250 are driven in opposite directions, so that the two hook bodies 280 are respectively hooked on the two sides of the lock rod 110, forming the limiting of the lock rod 110. When the lock rod 110 is inserted into the lock hole 230, the engaging portion 111 at the end thereof will be in contact with the two hook bodies 280, and with the further insertion of the lock rod 110, the two hook bodies 280 will slide along the first sliding groove 221 and the second sliding groove 222 respectively under the pushing of the engaging portion 111, and the compression spring 260 will be compressed, until the engaging portion 111 completely enters between the two hook bodies 280, at this time, under the elastic action of the compression spring 260, the two hook bodies 280 will be tightly hooked on the two sides of the engaging portion 111, realizing the locking of the lock rod 110. When unlocking, the user only needs to pinch the first lock catch 240 and the second lock catch 250 with one hand, so that the two hook bodies 280 overcome the elastic force of the compression spring 260 and move away from each other, thereby providing space to release the lock rod 110, realizing unlocking. This design not only makes the unlocking process simple and fast, but also improves the use convenience and user experience of the folding tent.

[0044] Based on the above embodiment, in an implementable manner of the utility model, Figure 1 As shown, the first guide surface 281 is arranged on the hook body 280 and is inclined at a predetermined angle, and correspondingly, the second guide surface 112 in the shape of a hemisphere is arranged on the engaging portion 111 of the lock rod 110, and the second guide surface 112 is adapted to the first guide surface 281, so that in the process of inserting the lock rod 110 into the lock hole 230, the second guide surface 112 of the engaging portion 111 can smoothly slide along the first guide surface 281 of the hook body 280 until the engaging portion 111 completely enters between the two hook bodies 280. The cooperation of the first guide surface 281 and the second guide surface 112 not only helps the smooth insertion of the lock rod 110, but also guides the hook body 280 to slide in the correct direction to a certain extent, thereby ensuring the accuracy and stability of the locking. At the same time, the inclined arrangement of the first guide surface 281 and the second guide surface 112 can also play a buffering role in the locking and unlocking process, reducing the friction and wear between the lock rod 110 and the hook body 280, and prolonging the service life.

[0045] In addition, as shown in Figure 4As shown, the third guide surface 231 is arranged at an angle, which allows the end of the lock rod 110 to smoothly slide along the third guide surface 231 until the lock rod 110 is fully inserted into the lock hole 230 during the process of inserting the lock rod 110 into the lock hole 230. The arrangement of the third guide surface 231 not only facilitates the smooth insertion of the lock rod 110, but also guides the lock rod 110 in the correct direction to some extent, thereby ensuring the accuracy and stability of the locking. At the same time, the inclined arrangement of the third guide surface 231 also plays a guiding and buffering role during the locking process, reducing the friction and wear between the lock rod 110 and the mounting disc 210, and further prolonging the service life.

[0046] In another embodiment of the present application, as shown in the drawings, Figure 1 In order to connect the center lock device for the folding tent with the framework of the folding tent, a plurality of first mounting tenons 211 are arranged on the outer side of the mounting disc 210 in the present embodiment, and the adjacent first mounting tenons 211 are matched to form a clamping space for mounting the end of the framework and a matching structure for mounting the pivot of the end of the framework. During the unlocking and locking of the center lock, the corresponding installed framework can be adaptively rotated through the first mounting tenons 211, thereby switching between the storage and opening states of the folding tent.

[0047] Correspondingly, a plurality of second mounting tenons 120 are arranged on the outer side of the upper locking piece 100, and specifically, as shown in the drawings, Figure 1 The upper locking piece 100 further includes a top disc seat 130, and the end of the lock rod 110 away from the lower locking piece 200 is fixed on the top disc seat 130 to form a stable and connected combined structure. The second mounting tenons 120 are preferably arranged on the outer side of the top disc seat 130, and the adjacent second mounting tenons 120 are matched to form a clamping space for mounting the end of the framework and a matching structure for mounting the pivot of the end of the framework. During the unlocking and locking of the center lock, the corresponding installed framework can be adaptively rotated through the second mounting tenons 120, thereby cooperating with the first mounting tenons 211 on the lower locking piece 200 to realize the stable support and convenient folding of the folding tent. This design not only enhances the structural stability of the folding tent, but also improves the convenience and flexibility of its use.

[0048] In addition, in order to ensure the position stability of the first lock catch 240 and the second lock catch 250 after unlocking, avoid that they are accidentally moved due to external force, and affect the accuracy of relocking, the utility model also sets the limiting groove 290 on the base 220 corresponding to the positions of the first lock catch 240 and the second lock catch 250. After unlocking, the first lock catch 240 and the second lock catch 250 will be restored to the initial position under the action of the compression spring 260, at this time, part of their structure will be embedded in the limiting groove 290, thereby being stably limited. Such design not only improves the use reliability of the central locking device, but also provides the user with more stable and safe folding tent use experience.

[0049] Based on the above embodiment, the utility model provides a central locking device for folding tent, through setting the first lock catch 240 and the second lock catch 250 relatively slidable in the lower locking piece 200, and utilizing the elastic connection to make them form the hooking of the locking lever 110, thereby realizing the locking of the position of the locking lever 110. When unlocking, the user only needs to pinch the first lock catch 240 and the second lock catch 250 with one hand, and can easily realize unlocking, and the other hand can control the folding tent framework after unlocking, so that the operation process is simple, and the folding tent is convenient for the user to control. In addition, the utility model also improves the locking accuracy, stability and service life of the central locking device through a series of ingenious structure designs, such as setting the first guide surface 281, the second guide surface 112 and the third guide surface 231. Therefore, the utility model has wide application prospect and important practical value.

[0050] Based on the above embodiment, the actual use process of the utility model is as follows:

[0051] When the user uses the folding tent, first, the framework of the tent needs to be unfolded, the user aligns the upper locking piece 100 with the lower locking piece 200, and inserts the locking lever 110 into the lock hole 230. In the process of inserting the locking lever 110, the clamping part 111 at the end of the locking lever 110 will smoothly slide along the third guide surface 231 until the clamping part 111 completely enters between the two hook bodies 280. At this time, under the elastic action of the compression spring 260, the two hook bodies 280 will tightly hook on both sides of the clamping part 111, realize the locking of the locking lever 110, and thus complete the support of the folding tent.

[0052] When the user needs to fold the tent, the user only needs to pinch the first lock catch 240 and the second lock catch 250 with one hand to make them close to each other against the elastic force of the compression spring 260, at this time, the first lock catch 240 and the second lock catch 250 and the hooking structure of the lock rod 110 move away from the lock rod 110, thereby releasing the lock rod 110, achieving unlocking.
