Description

Technical Field

[0001] The utility model relates to the field of children's products, in particular to a folding base of a playbed. Background Art

[0002] A children's playbed is primarily composed of a playbed frame and a playcloth. The playcloth forms a safe space for children to play in, preventing them from climbing out and falling. Existing baby crib frames consist of four sets of support rod structures, four sets of folding surround rod structures, and a folding base. The four sets of support rod structures are distributed at four corners, with each set of folding surround rod structures hinged between the tops of two adjacent sets of support rod structures. The folding base is connected to the bottoms of the four sets of support rod structures. The folding base of the existing baby crib frame includes a connecting base, four bottom support rods rotatably connected to the connecting base at one end, and two foot support rods rotatably connected to the connecting base at one end. The other end of each foot support rod is supported on the ground. The four bottom support rods form an "X"-shaped structure when connected to the connecting base, and the two foot support rods are symmetrically arranged. When the connecting base is lifted upward, the four bottom support rods and two foot support rods can fold upward with them. However, the folded four bottom support rods and two foot support rods are not further positioned, making them prone to falling apart after folding. Utility Model Content

[0021] Reference Figure 1 and Figure 2A folding base for a playpen includes a connecting base 1, a rotating base 2, a base 3, a rotating rod 4, four bottom rods 5, and two supporting leg rods 6. The connecting base 1, rotating base 2, and base 3 are arranged sequentially from top to bottom. The rotating rod 4 passes through the connecting base 1, rotating base 2, and base 3, and is fixedly connected to the rotating base 2 by a pin. The four bottom rods 5 are arranged in an "X" shape, and the two supporting leg rods 6 are arranged symmetrically. Four rod seats 7 are hinged to the bottom of the connecting base 1, each rod seat 7 corresponding to a bottom rod 5. One end of each bottom rod 5 is connected to the rod seat 7, and the rod seat 7 is hinged to the connecting base 1 via a pin. The specific hinge method of the rod seat 7 and the connecting base 1 is prior art and will not be repeated here. A first linkage rod 8 is hinged between the bottom of the rod seat 7 and the outer periphery of the base 3. One end of the supporting foot rod 6 is hinged to the bottom of the connecting seat 1. One end of the supporting foot rod 6 is hinged to the connecting seat 1 through a pin. The specific hinge method of one end of the supporting foot rod 6 and the connecting seat 1 is the existing technology and will not be repeated here. A second linkage rod 9 is hinged between the supporting foot rod 6 and the outer periphery of the base 3. The front and rear ends of the rotating seat 2 are each provided with two interference parts 10, and a rod groove 11 is provided between the two interference parts 10. Each rod seat 7 corresponds to one interference part 10. When the bottom rod 5 is unfolded, the interference part 10 interferes with the rod seat 7. When the bottom rod 5 is folded, the interference part 10 is misaligned with the rod seat 7. When the supporting foot rod 6 is unfolded, it is misaligned with the rod groove 11. After folding, one end of the supporting foot rod 6 is located in the rod groove 11. The rotating seat 2 is elastic.

[0022] Reference Figure 1 and Figure 2 The top of the rotating rod 4 is hinged with a handle piece 41, and the handle piece 41 is hinged to the top of the rotating rod 4 through a pin. The handle piece 41 can be flipped up and down. After the handle piece 41 is flipped upward, the rotating rod 4 can be rotated and lifted.

[0023] Reference Figures 1 to 6 The top surface of the rotating seat 2 is provided with a first limiting portion 12 and a second limiting portion 13 arranged in a front-to-rear manner. The bottom of the connecting seat 1 is provided with a first arc-shaped groove 14 and a second arc-shaped groove 15. The first limiting portion 12 and the second limiting portion 13 are respectively located in the first arc-shaped groove 14 and the second arc-shaped groove 15. A spring 16 is provided in the second arc-shaped groove 15. One end of the spring 16 abuts against the second limiting portion 13, and the other end of the spring 16 abuts against a side wall of the second arc-shaped groove 15. The cooperation between the first limiting portion 12 and the first arc-shaped groove 14, and the cooperation between the second limiting portion 13 and the second arc-shaped groove 15 is used to limit the rotation angle of the rotating seat 2. In this embodiment, the rotation angle of the rotating seat 2 is 90°. When the rotating seat 2 rotates, the spring 16 is compressed.

[0024] Reference Figures 1 to 4 、 Figure 7A “┏”-shaped cutout 17 is provided at the bottom of one end of the rod seat 7 close to the connecting seat 1. When the bottom rod 5 is unfolded, the front end of the interference portion 10 conflicts with the vertical part of the cutout 17, and the top of the interference portion 10 conflicts with the horizontal part of the cutout 17. At this time, if the rotating rod 4 is directly lifted, the rotating rod 4, the rotating seat 2 and the connecting seat 1 cannot be lifted, and the folding base cannot be folded.

[0025] Reference Figures 1 to 4 The bottom of the end of the rod seat 7 away from the connecting seat 1 is provided with a first hinge groove 18 that runs through from front to back and is open at the bottom. The outer periphery of the base 3 is provided with four second hinge grooves 19 that run through from top to bottom and are open at the front end. Each second hinge groove 19 corresponds to a rod seat 7. The first linkage rod 8 is hinged between the corresponding first hinge groove 18 and the second hinge groove 19. The two ends of the first linkage rod 8 are respectively hinged in the first hinge groove 18 and the second hinge groove 19 through a pin. The outer periphery of the base 3 is provided with two third hinge grooves 20 that run through from top to bottom and are open at the front end. Each third hinge groove 20 corresponds to a supporting foot rod 6. The second linkage rod 9 is hinged between the corresponding third hinge groove 20 and the side surface of the supporting foot rod 6. The two ends of the second linkage rod 9 are respectively hinged in the third hinge groove 20 and on the side surface of the supporting foot rod 6 through a pin.

[0026] Reference Figures 1 to 8 The design principle of the present invention is as follows: when the bottom rod 5 is unfolded, the interference portion 10 conflicts with the rod seat 7, and the supporting leg rod 6 is misaligned with the rod groove 11 when unfolded, and the folding base cannot be folded at this time. When the folding base needs to be folded, hold the handle 41 and rotate the rotating rod 4, and the rotating rod 4 drives the rotating base 2 to rotate. When the rotating base 2 rotates 90°, the interference part 10 and the rod seat 7 are misaligned to release the restriction. Then the rotating rod 4 is lifted, so that the rotating base 2 and the connecting base 1 are lifted up. As the connecting base 1 is lifted, the four bottom rods 5 and the two supporting foot rods 6 are folded. After folding, one end of the supporting foot rod 6 is located in the rod groove 11, thereby limiting the supporting foot rod 6. At the same time, the four bottom rods 5 are connected to the base 3 through the first linkage rod 8, and the two supporting foot rods 6 are connected to the base 3 through the second linkage rod 9, and the rotating rod 4 passes through the base 3. Therefore, the two supporting foot rods 6 and the four bottom rods 5 after folding can be effectively positioned and will not fall apart. When the folding base is to be unfolded, the four bottom rods 5 and the two supporting leg rods 6 are unfolded, and under the action of the spring 16, the rotating base 2 automatically returns to its original position, and the abutting portion 10 abuts against the rod base 7 again.

[0027] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
