Description

Technical Field

[0001] This utility model relates to the field of baby crib technology, and in particular to a safety locking device for the base of a baby playpen. Background Technology

[0002] Baby playpens are common facilities for babies to play and rest. The stability of their base is directly related to the baby's safety. Existing baby playpens usually rely on simple buckles or bolts for locking, which can easily lead to instability during use. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a safety locking device for the base of an infant playpen.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A safety locking device for a baby playpen base includes a frame, a bed body at the bottom of the frame, support rods movably mounted on both sides of the frame, a folding mechanism installed between the two support rods, the folding mechanism being located below the bed body, and a locking mechanism at its bottom.

[0006] The locking mechanism has a movable ring on the outside, and multiple support tubes are provided on both ends of the movable ring. One side of the support tube is connected to the movable ring through the first connecting block, and the other side is connected to the support rod through the fixing block.

[0007] Furthermore, in a preferred configuration, a locking mechanism is installed below the folding mechanism, and a movable ring is movably mounted on the locking mechanism via a limit block.

[0008] In addition, a preferred structure is that the two sides of the surface of the movable ring are connected to the connecting block of the support tube through the first connecting block, and the connecting block is provided with a through groove, and a rotating block is provided in the through groove.

[0009] Furthermore, a preferred structure is to rotatably connect multiple support tubes together via nodes.

[0010] The beneficial effects of this utility model are as follows: by setting a locking mechanism and a support tube, an additional layer of safety protection can be added to the original fixed structure of the baby play bed, thereby forming a double protection mechanism, which greatly improves the stability and protection of the baby play bed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-8A safety locking device for a baby playpen base includes a frame 1, support rods 2, a folding mechanism 3, a locking mechanism 4, support tubes 5, casters 6, and a bed 7. The bed 7 is housed within the frame 1. Support rods 2 are movably mounted on both sides of the frame 1. A folding mechanism 3 is located between the two support rods 2. The folding mechanism 3 is located below the bottom of the bed 7. The locking mechanism 4 is fixedly mounted below the folding mechanism 3. Grooves are formed on both sides of the surface of the locking mechanism 4. Limit blocks are movably mounted in the grooves via springs. The limit blocks are arc-shaped, and the bottom of the limit blocks is horizontal to the outer side of the locking mechanism 4. Multiple rotating parts are provided on the outer side of the bottom of the support rods 2. The bottom of the rotating parts is movably connected to the casters 6.

[0022] A movable ring is mounted on the surface of the locking mechanism 4. A limit groove is opened on the outer side of the movable ring. The limit groove corresponds to the position of the limit block on the surface of the locking mechanism 4. First connecting blocks are fixedly installed on both sides of the surface of the movable ring, and multiple support tubes 5 are provided on both sides of the movable ring. Connecting blocks are fixedly installed at both ends of the support tubes 5. Through grooves are opened in the connecting blocks. One connecting block is rotatably connected to the first connecting block through a first rotating block. The connecting block on the other side is connected to the node. Three second connecting blocks are provided on the outer side of the node. Rotating rods are rotatably installed in the second connecting blocks. One second connecting block on the outer side of the node is rotatably connected to the support tube 5 near the locking mechanism 4. The other two second connecting blocks are connected to the fixed blocks on the support rod 2 through the support tubes 5.

[0023] In this embodiment, when using the baby playpen, the folding mechanism 3 between the support rods 2 is opened. At this time, the limiting block on one side of the locking mechanism 4 is pressed, and the spring in the limiting block will be forced to move inward. When it moves to a certain distance, the movable ring will move downward, causing the support tube 5 to rotate. At this time, the fixing block on the support rod 2 will drive the other two support tubes 5 to rotate.

[0024] When the support rod 2 moves to its maximum distance, the limiting block on the other side of the locking mechanism 4 will move inward due to the pressure of the movable ring. When the movable ring moves downward a certain distance, the limiting block will be pressed by the inner spring and fixed in the limiting groove of the movable ring, thus limiting the movable ring. At this time, the folding mechanism 3 is fully extended, fixing the support rod 2. The supporting tube 5 is fixed by the fixing block on the support rod 2. Since the movable ring on the other side is limited by the limiting block, the supporting tube 5 will be limited and fixed. In addition, the universal wheel 6 can rotate upward through the rotating part on the support rod 2 to produce a rocking bed effect. When not in use, press the limiting block on the locking mechanism 4 and fold it away through the folding mechanism 3.

[0025] This invention, by setting a locking mechanism and a support tube, can add a layer of safety protection to the original fixed structure of the baby playbed, thereby forming a double protection mechanism and greatly improving the stability and protection of the baby playbed.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
