Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products technology, and in particular to a folding stool core. Background Technology

[0002] Newborn babies cannot walk independently and usually need to be carried by family members when going out. However, mothers' hands may find it difficult to hold their babies for extended periods. Therefore, a baby carrier with a built-in seat has been invented. The baby sits on the seat and is secured to the mother by the carrier, freeing up the mother's hands and making it easier to take the baby out. The seat usually consists of a support plate that fits against the mother's abdomen and a seat for the baby to sit on. To facilitate storage, foldable seat carriers have been invented that can stow away the seat.

[0003] To prevent the seat from rotating downwards due to gravity while the baby is sitting on it, a locking mechanism is essential when the seat is unfolded. Existing folding stools require manual operation of the locking mechanism to fold or unfold, which involves multiple steps, making them cumbersome and less convenient. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a folding stool core. To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0005] A folding stool core includes a fixed plate for conforming to the abdomen and a rotatable seat plate, the fixed plate and the seat plate being rotatably connected. The fixed plate has a mounting cavity at one end, and the seat plate has a mounting block at one end. The mounting block rotates synchronously with the seat plate and is rotatably assembled into the mounting cavity. The mounting cavity is provided with a longitudinally movable locking block and a rotatable engaging block. The locking block and the engaging block can be engaged with each other and both are provided with a return spring at the bottom. A limiting part is provided between the locking block and the mounting block. The folding stool core includes a folded state, an unfolded state, and a fully unfolded state; In the unfolded state, the seat panel close to the fixed plate rotates upward until the limiting part between the mounting block and the locking block forms a snap to restrict the seat panel from rotating downward. In the fully unfolded state, the seat panel continues to rotate upwards, and the rotating mounting block gradually pushes the locking block downwards until it engages with the locking block. The locking block disengages from the mounting block, the locking state of the limiting part is released, and the seat panel can be rotated downwards and folded. In the folded state, the seat plate rotates downwards and approaches the fixed plate, the mounting block rotates and gradually pushes the locking block to rotate, the locking state of the locking block and the locking block is released, and the locking block and the locking block are reset by the return spring.

[0006] Furthermore, the limiting part includes a recessed limiting groove on the locking block and a limiting post on the mounting block that rotates with the mounting block. The limiting post is adapted to the limiting groove. When the seat plate rotates upward and unfolds, the limiting post is embedded in the limiting groove to form a fixed position to limit the downward rotation of the seat plate.

[0007] Furthermore, the mounting block has a first push block extending downward in an arc shape at one end near the locking block. The seat plate drives the mounting block to rotate upward, and the first push block pushes the locking block downward until the locking block forms a locking engagement.

[0008] Furthermore, a second push block is provided at one end of the mounting block near the engaging block. The seat plate drives the mounting block to rotate downwards, and the second push block pushes the engaging block to rotate and disengage from the locking block. The locking block and the engaging block are reset by a reset spring.

[0009] Furthermore, a snap-fit ​​block is provided on the side of the snap-fit ​​block near the locking block, and a snap-fit ​​groove corresponding to the snap-fit ​​block is provided on the locking block. The snap-fit ​​block and the locking block are snapped together by the snap-fit ​​block being embedded in the snap-fit ​​groove.

[0010] Furthermore, the end of the snap-fit ​​block is provided with an inclined guide surface, and the locking block is provided with a guide surface. The guide surface is adapted to the guide surface, and when the locking block moves downward, the guide surface is embedded into the snap-fit ​​groove along the guide surface.

[0011] Furthermore, the locking block is provided with a shaft hole, and the locking block is rotatably assembled into the mounting cavity by passing a shaft with a size adapted to the shaft hole through the shaft hole.

[0012] Furthermore, the locking block is provided with a movable groove, and the locking block is fixed by a shaft passing through the movable groove. The movable groove is the same width as the shaft and its length is greater than that of the shaft. When the locking block moves up and down, the shaft moves within the movable groove.

[0013] Furthermore, the fixing plate has an arc-shaped profile.

[0014] Furthermore, the seat plate and the fixing plate are provided with a number of ventilation holes.

[0015] Compared with the prior art, the beneficial effects that this utility model can achieve are: This utility model's folding stool core includes a folded state, an unfolded state, and a fully unfolded state. In the unfolded state, the seat panel, positioned close to the fixed plate, rotates upwards until a locking mechanism between the mounting block and the locking block engages, preventing the seat panel from rotating downwards. In the fully unfolded state, the unfolded seat panel continues to rotate upwards, and the mounting block's rotation gradually pushes the locking block downwards until it engages with a locking block. After the locking block disengages from the mounting block, the locking mechanism is released, and the seat panel can be folded downwards. In the folded state, the seat panel rotates downwards towards the fixed plate, and the mounting block rotates, gradually pushing the locking block to rotate. The locking mechanism between the locking block and the locking block is released, and the locking block and locking block are reset by a return spring. This design only requires rotating the seat panel upwards to a preset angle to open it for the baby to sit on. The locking mechanism prevents the seat panel from rotating downwards. To fold it, simply continue rotating the seat panel upwards to release the locking mechanism, allowing it to be folded downwards for storage. The folding and unfolding process requires fewer steps, making it convenient and user-friendly. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, a folding stool core includes a fixed plate 1 for conforming to the abdomen and a rotatable seat plate 2. The fixed plate 1 and the seat plate 2 are rotatably connected. The seat plate 2 can be rotated out for the baby to sit on, or rotated to be stored close to the fixed plate 1. The fixed plate 1 has a mounting cavity 3 at one end, and the seat plate 2 has a mounting block 4 at one end. The mounting block 4 rotates synchronously with the seat plate 2 and is rotatably fitted into the mounting cavity 3. The mounting cavity 3 has a longitudinally movable locking block 5 and a rotatable engaging block 6. The locking block 5 and the engaging block 6 can engage with each other, and both have a return spring 7 at their bottom. After the locking block 5 and the engaging block 6 move, they are reset by the rebound force of the return spring 7. A limiting part 8 is provided between the locking block 5 and the mounting block 6. When the seat plate 2 is rotated upwards and unfolded for use, the limiting part 8 limits its movement, preventing the seat plate 2 from rotating downwards due to gravity when the baby is sitting on it.

[0024] The folding stool core includes a folded state, an unfolded state, and a fully unfolded state: In the unfolded state, the seat plate 2, which is close to the fixed plate 1, rotates upward until the limiting part 8 between the mounting block 4 and the locking block 5 forms a latch to restrict the seat plate 2 from rotating downward; In the fully unfolded state, the seat plate 2, which is in the unfolded state, continues to rotate upward, and the mounting block 4 rotates to gradually push the locking block 5 downward until it forms a latch with the engaging block 6. After the locking block 5 moves away from the mounting block 4, the latching state of the limiting part 8 is released, and the seat plate 2 can rotate downward and fold; In the folded state, the seat plate 2 rotates downward and approaches the fixed plate 1, and the mounting block 4 rotates and gradually pushes the engaging block 6 to rotate. The locking state of the locking block 5 and the engaging block 6 is released, and the locking block 5 and the engaging block 6 are reset by the return spring 7. This design allows the seat panel 1 to be opened for the baby to sit on simply by rotating it upwards to a preset angle. The limiting part 8 restricts the seat panel 2 from rotating downwards. When folding is required, simply continue to rotate the seat panel upwards to release the limiting part 8, and then rotate it downwards to fold and store it. The steps required for folding or unfolding are few, making it convenient to use and meeting the user's needs for ease of use.

[0025] The limiting part 8 includes a recessed limiting groove 9 on the locking block 5 and a limiting post 10 on the mounting block 4 that rotates with the mounting block 4. The limiting post 10 is adapted to the limiting groove 9. When the seat plate 2 is rotated upward and unfolded, it is fixed by the limiting post 10 being embedded in the limiting groove 9, which is used to restrict the seat plate 2 from rotating downward. At this time, the seat plate 2 can only rotate upward and cannot rotate downward, preventing the baby from sitting on the seat plate 2 and causing the seat plate 2 to rotate downward.

[0026] The mounting block 4 has a first push block 11 extending downward in an arc shape at one end near the locking block 5. The arc shape matches the rotation of the seat plate 2. The seat plate 2 drives the mounting block 4 to rotate upward, and the first push block 11 moves downward, pushing the locking block 5 downward until it engages with the locking block 6. At this time, the limiting state of the locking block 5 and the mounting block 4 at the misalignment limiting part 8 is released, the locking block 6 restricts the locking block 5 from moving upward and resetting, and the seat plate 2 can rotate and fold downward without being restricted by the limiting part 8.

[0027] The mounting block 4 is provided with a second push block 12 at one end near the locking block 6. The seat plate 2 drives the mounting block 4 to rotate downwards. The second push block 12 pushes the locking block 6 to rotate. After the seat plate 2 is completely folded, the locking block 6 disengages from the locking block 5. The locking block 5 and the locking block 6 are reset by the reset spring 7.

[0028] The engaging block 6 is provided with a engaging block 13 on the side close to the locking block 5. The locking block 5 is provided with a engaging groove 14 corresponding to the engaging block 13. The engaging block 6 and the locking block 5 are engaged by the engaging block 13 being embedded in the engaging groove 14.

[0029] The end of the snap-fit ​​block 13 is provided with an inclined guide surface 15, and the locking block 5 is provided with a guide surface 17. The guide surface 17 is adapted to the guide surface 15. When the locking block 5 moves downward, the guide surface 15 moves along the guide surface 17 and gradually embeds into the snap-fit ​​groove 14. The setting of the guide surface 15 and the guide surface 17 helps the snap-fit ​​block 13 to embed into the snap-fit ​​groove 14, making the seat plate 2 rotate more smoothly.

[0030] The locking block 6 is provided with a shaft hole 18. The locking block 6 is rotatably assembled into the mounting cavity 3 by passing a shaft with a size that matches the shaft hole 18 through the shaft hole 18. Therefore, the locking block 6 can only rotate and cannot be displaced.

[0031] The locking block 5 is provided with a movable groove 19. The locking block 5 is fixed by a shaft passing through the movable groove 19. The movable groove 19 is the same width as the shaft and its length is greater than that of the shaft. The length of the movable groove 19 is the distance that the shaft can move up and down. When the first push block 11 pushes the locking block 5 to move up and down, the shaft also moves up and down in the movable groove 19.

[0032] The fixing plate 1 has an arc-shaped profile that fits the abdominal contour and conforms to ergonomic design, making this folding stool core more comfortable to wear.

[0033] The seat plate 2 and the fixing plate 1 are provided with a number of ventilation holes 16, which helps to dissipate heat and reduces material consumption.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
