Description

Technical Field

[0001] The utility model relates to a baby fence frame and belongs to the technical field of children's products. Background Art

[0002] A baby playpen is a household device used to ensure infant safety, typically made of sturdy materials such as wood, metal, or plastic. Its primary purpose is to create an enclosed area, preventing infants or young children from coming into contact with dangerous objects or entering unsafe areas such as stairs or kitchens. Common baby playpens are mostly fixed structures, making them difficult to store. To address this issue, a utility model patent in China with Chinese Patent Authorization Publication No. CN218899013U discloses a baby playpen that features connecting holes in the middle of a first crossbeam and a second crossbeam. Pins are inserted into the connecting holes of the two first crossbeams, securing the two crossbeams. The pins are then used to maintain a flexible connection between the two crossbeams, allowing them to be folded for easy storage. However, the following problems still exist when it is used: it fixes the second mounting male part on the vertical rod by inserting the elastic pin into the installation groove, thereby ensuring its stability in the unfolded state. However, it does not provide an anti-accidental touch component at the position where the elastic pin is inserted into the installation groove. If the baby's arm touches the elastic pin during the movement of the baby's arm, causing the baby to press the elastic pin inward, at this time, the second mounting male part may be separated from the elastic pin, causing it to slide on the vertical rod, thereby causing the state of the fence frame to change, and it can no longer play a protective role. The baby may fall off the fence frame, posing a certain safety hazard. Utility Model Content

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example: Please refer to Figures 1 to 7 This embodiment provides a baby fence frame, comprising four vertical bars 1 and a folding mechanism for connecting adjacent vertical bars 1 in pairs. The four vertical bars 1 cooperate with the folding mechanism to form a rectangular structure, so as to provide suitable enclosure for the baby therein. In this embodiment, the folding mechanism comprises a first mounting portion 3, a second mounting portion 14, a folding rod 15, and a third mounting portion 16. The first mounting portion 3 is provided on each vertical bar 1, and each first mounting portion 3 is slidably connected to the corresponding vertical bar 1. The second mounting portion 14 is provided at the top of each vertical bar 1, and each second mounting portion 14 is fixedly provided on the top of the corresponding vertical bar 1. The folding rods 15 are symmetrically arranged between adjacent vertical bars 1, and the folding rods 15 are arranged in an "X"-shaped structure. The middle portion of the folding rod 15 is a movable connection structure, which enables the folding rod 15 to perform a suitable folding action. The third mounting portion 16 is arranged between the folding rods 15 on both sides. The two ends of the folding rods 15 on both sides that are close to each other are connected to the third mounting portion 16, and the two ends of the folding rods 15 on both sides that are away from each other are respectively connected to the first mounting portion 3 and the second mounting portion 14 at the corresponding positions. The connections between the folding frame and the first mounting portion 3, the second mounting portion 14 and the third mounting portion 16 are all rotating connections to achieve the corresponding folding action.

[0024] Through the above-mentioned arrangement, when the first mounting portion 3 slides along the vertical rod 1, it can drive the corresponding end of the folding rod 15 to move, so that the end of each folding rod 15 rotates on the second mounting portion 14 and the third mounting portion 16 at the corresponding position to meet the folding action, so that the fence frame can change between the folding state and the enclosing state.

[0025] In this embodiment, an elastic pin 2 is provided on one of the vertical bars 1. A first mounting portion 3 on the same vertical bar 1 as the elastic pin 2 is provided with a connecting structure for inserting the elastic pin 2. The elastic pin 2 is inserted into the connecting structure to securely connect the first mounting portion 3 to the corresponding vertical bar 1, thereby securing the fence frame in its enclosing state. That is, once the first mounting portion 3 is secured to the vertical bar 1, the folding rod 15 cannot fold, thereby securing the fence frame in its enclosing state. A protective assembly is also provided on the sidewall of the first mounting portion 3. The protective assembly includes a protective plate 4 slidably connected to the sidewall of the first mounting portion 3. A sliding groove 5 is defined in the sidewall of the first mounting portion 3. A slider 6 slidably connected to the sliding groove 5 is fixedly provided on the sidewall of the protective plate 4 proximal to the first mounting portion 3. A spring 7 is provided in the sliding groove 5. The spring 7 connects the slider 6 to the sidewall of the sliding groove 5. When the slider 6 moves within the sliding groove 5, the length and shape of the spring 7 can be changed. When the spring 7 is in a normal state, the protective plate 4 is positioned on the first mounting portion 3 so as to cover the connection structure.

[0026] In this embodiment, the connection structure includes a first connection groove 8 and a second connection groove 9. The first connection groove 8 is opened on the side wall of the first mounting part 3 close to the elastic pin 2, and the second connection groove 9 is opened on the side wall of the first mounting part 3 close to the protective plate 4. The second connection groove 9 and the first connection groove 8 are connected together by setting a connection hole 10. The elastic pin 2 can enter the first connection groove 8 and enter the second connection groove 9 by passing through the connection hole 10 to fix the vertical rod 1 and the first mounting part 3 together. When the spring 7 is in normal state, the protective plate 4 can cover the second connection groove 9, thereby covering the elastic pin 2 inserted into the second connection groove 9, so as to avoid the situation where the elastic pin 2 releases the fixed connection between the first mounting part 3 and the vertical rod 1 due to the baby's accidental touch of the elastic pin 2, thereby ensuring the reliability of the fence frame during enclosing.

[0027] In order to facilitate the elastic pin 2 to enter the first connecting groove 8, an auxiliary arc wall 11 is opened at the slot position of the first connecting groove 8. When the elastic pin 2 passes through, the auxiliary arc wall 11 can cause the elastic pin 2 to retract into the vertical rod 1 so that the elastic pin 2 can smoothly enter the first connecting groove 8.

[0028] To facilitate the monitoring personnel's pressing of the elastic pin 2, a flexible baffle 12 is provided in the second connecting groove 9. One end of the flexible baffle 12 is connected to the groove wall of the second connecting groove 9. When the elastic pin 2 enters the second connecting groove 9, it can push outward the end of the flexible baffle 12 not connected to the second connecting groove 9. When this end of the flexible baffle 12 is pushed out by the elastic pin 2, the flexible baffle 12 undergoes corresponding flexible deformation. The flexible baffle 12 can be made of common flexible materials, such as flexible plastic, flexible rubber, etc.

[0029] In order to prevent the flexible baffle 12 from interfering with the movement of the protective plate 4 after being pushed out by the elastic pin 2, a groove 13 is further opened on the plate wall of the protective plate 4 close to the first mounting part 3, and the groove 13 is for the flexible baffle 12 pushed out by the elastic pin 2 to enter.

[0030] The working principle of the present invention is that when the playpen is needed, the guardian pushes the first mounting portion 3 upward, causing it to slide upward along the vertical rod 1. When the first mounting portion 3 slides to contact the elastic pin 2, the first mounting portion 3, through the provision of the auxiliary arc wall 11, can correspondingly contract the elastic pin 2, allowing the elastic pin 2 to smoothly enter the first connecting groove 8. The guardian then continues to push the first mounting portion 3 upward, causing the elastic pin 2 to move within the first connecting groove 8 to the connection hole 10. At this time, the elastic pin 2 resets and can pass through the connection hole 10 and extend into the second connecting groove 9, pushing the flexible baffle 12 outward. At this time, the elastic pin 2, through the connection of the connection hole 10, can secure the first mounting portion 3 to the vertical rod 1. As the first mounting portion 3 slides upward, the folding rod 15 folds accordingly, allowing the playpen to unfold into the enclosed position. Due to the protection plate 4 covering the elastic pin 2, the baby inside the playpen is unable to contact the elastic pin 2, thus ensuring that the playpen's state is difficult to change. When the fence frame needs to be stored, the guardian pushes the protective plate 4, and the slider 6 slides in the slide groove 5 to make the protective plate 4 move on the first mounting part 3 to expose the flexible baffle 12. After that, the guardian presses the flexible baffle 12 downward to withdraw the elastic pin 2 from the connecting hole 10. After that, the guardian pushes the first mounting part 3 downward to withdraw the elastic pin 2 from the first connecting groove 8. After that, the first mounting part 3 pushes the first mounting part 3 downward, and the folding rod 15 performs a corresponding folding action to make the fence frame become a folded state.

[0031] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
