[0047] In addition, the terms "first", "second" and the like appear only to distinguish the description and cannot be understood as indicating or implying relative importance.

[0048] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0049] Please refer to Figure 1 and Figure 2 , the embodiment provides a baby folding bed 100 with a locking mechanism, which comprises a bottom folding rod assembly 1, a locking mechanism 2, a first side frame 3, a second side frame 4, a first bottom edge rod assembly 5, a second bottom edge rod assembly 6, a bottom cross rod 7, a top edge rod assembly 8, a cover plate 9 (please refer to Figure 3 ) and a roller 10.

[0050] The first side frame 3 and the second side frame 4 are arranged at intervals, and the bottom folding rod assembly 1, the first bottom edge rod assembly 5, the second bottom edge rod assembly 6 and the two top edge rod assemblies 8 are connected between the first side frame 3 and the second side frame 4.

[0051] The bottom folding rod assembly 1, the first bottom edge rod assembly 5 and the second bottom edge rod assembly 6 are located at the bottom of the first side frame 3 and the second side frame 4, and the bottom folding rod assembly 1 is located between the first bottom edge rod assembly 5 and the second bottom edge rod assembly 6. The two top edge rod assemblies 8 are located at the top of the first side frame 3 and the second side frame 4, and are respectively located at the opposite sides of the first side frame 3 and the second side frame 4.

[0052] The cover plate 9 is reversibly connected to the upper part of the first side frame 3 or the second side frame 4, and when the first side frame 3 and the second side frame 4 are in the opposite folding state, the cover plate 9 can be turned to surround the first side frame 3 and the second side frame 4. When the first side frame 3 and the second side frame 4 are in the separated state, the cover plate 9 can be turned to the outside of the first side frame 3 or the second side frame 4 as a carrying basket. In this way, the cover plate 9 not only can cover the first side frame 3 and the second side frame 4 when the baby folding bed 100 with the locking mechanism is folded, so that the overall structure is compact, occupies less space, and prevents the baby folding bed 100 with the locking mechanism from being accidentally unfolded, but also can be turned to the outside of the first side frame 3 or the second side frame 4 as a carrying basket after the baby folding bed 100 with the locking mechanism is unfolded, thereby improving the practicability of the baby folding bed 100 with the locking mechanism.

[0053] The rollers 10 are installed at the bottom of the first side frame 3 and the second side frame 4, and the baby folding bed 100 with the locking mechanism can be conveniently moved by using the rollers 10.

[0054] Specifically, the bottom folding rod assembly 1 includes two bottom connecting rods 11 and a base 12 connected between the two bottom connecting rods 11. One end of each of the two bottom connecting rods 11 is hingedly connected to the base 12, and the other end of each of the two bottom connecting rods 11 is hingedly connected to the first side frame 3 and the second side frame 4, respectively. The base 12 is provided with a sliding hole in the vertical direction.

[0055] Please refer to Figures 2 to 4 The locking mechanism 2 includes a lock post 21, two auxiliary rods 22, a support seat 23, a lock tongue 24, an elastic reset member 25, a pull rope 26, and a pull handle 27. The lock post 21 is slidingly fitted in the sliding hole, and one end of the lock post 21 extending out of the base 12 is fixedly connected to the support seat 23. The two auxiliary rods 22 are connected to the lock post 21 through the support seat 23, and the two auxiliary rods 22 are hingedly connected to the support seat 23. A lock hole is formed in the side surface of the lock post 21, and a mounting hole is formed in the base 12 and communicates with the sliding hole. The lock tongue 24 is inserted into the mounting hole and is used to cooperate with the lock hole. The elastic reset member 25 has a restoring force for pushing the lock tongue 24 into the lock hole. One end of the pull rope 26 is connected to the lock tongue 24, and the other end of the pull rope 26 is connected to the pull handle 27. The pull handle 27 is used for being actuated by a user and pulling the lock tongue 24 out of the lock hole through the pull rope 26.

[0056] The working principle of the locking mechanism 2 is as follows:

[0057] When the baby folding bed 100 with the locking mechanism is unfolded, the lock tongue 24 can be clamped into the lock hole of the lock post 21 under the action of the elastic reset member 25, so that the bottom folding rod assembly 1 cannot be folded and unfolded, and the baby folding bed 100 with the locking mechanism is stably kept in the unfolded state, thereby avoiding that the baby folding bed 100 with the locking mechanism is accidentally folded due to accidental impact on the bottom folding rod assembly 1;

[0058] When the baby folding bed 100 with the locking mechanism needs to be folded, the user pulls the handle 27 to make the locking tongue 24 disengage from the locking hole, and then the baby folding bed 100 with the locking mechanism can be folded normally.

[0059] Preferably, the bottom connecting rods 11, the locking column 21 and the auxiliary rods 22 move in the same plane, and the movement direction of the locking column 21 is perpendicular to the plane. The two bottom connecting rods 11 are symmetrically arranged relative to the locking column 21, and the two auxiliary rods 22 are symmetrically arranged relative to the locking column 21. In this way, the locking mechanism 2 and the bottom folding rod assembly 1 are matched in a simple form, and the locking mechanism 2 is designed in a simple structure, which is convenient to assemble and low in cost.

[0060] Please refer to Figure 1 , Figure 3 and Figure 4 , the bottom cross rod 7 is vertically connected at the folding position of the first bottom edge rod assembly 5, the folding position of the second bottom edge rod assembly 6 and the folding position of the bottom folding rod assembly 1, and the locking tongue 24 and the elastic reset member 25 are both installed inside the bottom cross rod 7. In this way, the locking tongue 24 and the elastic reset member 25 are both hidden inside the bottom cross rod 7, which is not only stable in installation and not easy to be damaged, but also not easy to be accidentally opened by external collision.

[0061] The handle 27 is slidably installed on the first bottom edge rod assembly 5 or the second bottom edge rod assembly 6, and the pull rope 26 extends from the inside of the bottom cross rod 7 to the handle 27. In this way, the handle 27 of the locking mechanism 2 is located on the outside of the entire baby folding bed 100 with the locking mechanism, which is convenient for the user to operate the handle 27.

[0062] The handle 27 includes a cylindrical portion 271 and a pulling portion 272, the cylindrical portion 271 is sleeved on the first bottom edge rod assembly 5 or the second bottom edge rod assembly 6, and the pulling portion 272 is connected on the side of the cylindrical portion 271 and protrudes downward of the first bottom edge rod assembly 5 or the second bottom edge rod assembly 6. In this way, the user can put his foot under the first bottom edge rod assembly 5 or the second bottom edge rod assembly 6, and pull the handle 27 along the length direction of the first bottom edge rod assembly 5 or the second bottom edge rod assembly 6, so as to open the locking mechanism 2, and then push the bottom folding rod assembly 1 upward with the foot, so as to start folding the baby folding bed 100 with the locking mechanism. For the user, one foot can complete the operation, which is more convenient.

[0063] The elastic reset member 25 includes a fixing bolt 251 and a reset spring 252, the fixing bolt 251 is fixedly connected inside the bottom cross rod 7, and the reset spring 252 is connected between the fixing bolt 251 and the locking tongue 24, and the reset spring 252 has a spring force for pushing the locking tongue 24 into the locking hole. In this way, the elastic reset member 25 has a simple structure and is stable in installation, and can provide a larger pushing force to the locking tongue 24.

[0064] The working principle of the baby folding bed 100 with the locking mechanism provided in the embodiment is as follows:

[0065] In the unfolded state of the baby folding bed 100 with the locking mechanism, the lock tongue 24 can be clamped into the lock hole on the lock column 21 under the action of the elastic reset member 25, so that the bottom folding rod assembly 1 cannot be folded and stored, and the baby folding bed 100 with the locking mechanism is stably kept in the unfolded state.

[0066] When it is needed to fold and store the baby folding bed 100 with the locking mechanism, the user actuates the pull handle 27 to make the pull handle 27 pull the pull rope 26 and drive the lock tongue 24 to be separated from the lock hole, at this time, the bottom folding rod assembly 1 is pulled upward, the angle between the two bottom connecting rods 11 and the angle between the two auxiliary rods 22 gradually become smaller, the lock column 21 moves downward relative to the base 12, the two top edge rod assemblies 8 are folded and bent downward from the middle part, the first side frame 3 and the second side frame 4 are close to each other, and the cover plate 9 can be rotated to surround the first side frame 3 and the second side frame 4.

[0067] When it is needed to unfold and use the baby folding bed 100 with the locking mechanism, the user rotates the cover plate 9 to the outside of the first side frame 3 or the second side frame 4, and then relatively pulls apart the first side frame 3 and the second side frame 4, or presses the folding part of the bottom folding rod assembly 1 downward, or pulls the folding part of the top edge rod assembly 8 upward, in this process, the angle between the two bottom connecting rods 11 and the angle between the two auxiliary rods 22 gradually become larger, the lock column 21 moves upward relative to the base 12, until the lock hole of the lock column 21 and the lock tongue 24 move to the same height, the lock tongue 24 is clamped into the lock hole of the lock column 21 under the action of the elastic reset member 25, and the unfolding of the baby folding bed 100 with the locking mechanism is realized and stably kept.

[0068] The baby folding bed 100 with the locking mechanism provided in the embodiment has the following beneficial effects:

[0069] 1. The locking mechanism 2 is additionally provided, in the unfolded state of the baby folding bed 100 with the locking mechanism, the bottom folding rod assembly 1 cannot be folded and stored, and the baby folding bed 100 with the locking mechanism is stably kept in the unfolded state, so that the baby folding bed 100 with the locking mechanism is prevented from being accidentally folded and stored due to the accidental collision of the bottom folding rod assembly 1;

[0070] 2. The locking mechanism 2 does not increase the operation complexity of the baby folding bed 100 with the locking mechanism in unfolding or folding;

[0071] 3. The cover plate 9 can not only cover the first side frame 3 and the second side frame 4 when the baby folding bed 100 with the locking mechanism is folded, so that the overall structure is compact, occupies less space, and prevents the baby folding bed 100 with the locking mechanism from accidentally unfolding, but also can be flipped to the outside of the first side frame 3 or the second side frame 4 as a carrying frame after the baby folding bed 100 with the locking mechanism is unfolded, thereby improving the practicability of the baby folding bed 100 with the locking mechanism.

[0072] 4. The locking mechanism 2 uses the pull rope 26 to pull the lock tongue 24, and the pull handle 27 is arranged outside the baby folding bed 100 with the locking mechanism, so that the user can conveniently operate the locking mechanism 2, and the locking mechanism 2 has a simple structure and high movement reliability.

[0073] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
