Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products technology, and in particular to a foldable 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, a foldable seat design has been developed.

[0003] Existing foldable stool cores require pressing or moving the locking mechanism on the core before they can be folded, which involves multiple steps and is quite inconvenient to use. Utility Model Content

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

[0005] A foldable stool core includes a fixing plate for conforming to the abdomen and a foldable seat plate, the fixing plate and the seat plate being rotatably connected. The fixed plate has a mounting cavity at its end, and the seat plate is rotatably connected to the mounting cavity at its end. The mounting cavity is provided with a locking unit, which includes a locking block, a first engaging block, and a second engaging block. The locking block, the first engaging block, and the second engaging block are rotatably mounted in the mounting cavity. A limiting part is provided between the locking block and the seat plate, and the locking block rotates synchronously with the seat plate through the limiting part. The seat panel includes a first open state, a second open state, and a folded state. In the folded state, the seat panel is folded up close to the side of the fixed panel; In the first open state, the seat panel in the folded state drives the locking block to rotate counterclockwise, the first engaging block engages with the locking block and restricts the locking block from rotating clockwise, and the seat panel is opened so that the baby can sit on it; In the second open state, the seat panel in the first open state continues to rotate counterclockwise. The locking block rotates and releases the locking state of the first locking block, and drives the first locking block to rotate and abut against one side of the second locking block. The end of the first locking block used for locking is away from the end of the locking block used for locking. At this time, the seat panel can be rotated arbitrarily for folding.

[0006] Furthermore, the locking block is provided with several consecutive gear parts, which form a lock with the first engaging block through the gear parts; when the seat plate is rotated open, the locking block first drives the first engaging block to rotate clockwise to disengage from the current gear part, and then the spring's rebound force drives the first engaging block to rotate clockwise to engage with the adjacent gear part.

[0007] Furthermore, the first engaging block is provided with a protruding engaging block, which is adapted to the gear part, and the engaging block and the gear part form a limiting position.

[0008] Furthermore, the first locking block is provided with a protruding stop. When the locking block drives the first locking block to rotate, the stop pushes the second locking block to rotate until it passes the second locking block. The second locking block rotates and resets by the spring's rebound force, pressing against one side of the stop. The locking block moves away from the gear part, so that the first locking block is in the unlocked state.

[0009] Furthermore, spring posts are provided at the ends of the first and second locking blocks, and springs are sleeved on the spring posts.

[0010] Furthermore, the end of the seat plate is provided with a mounting block adapted to the mounting cavity, and the mounting block is axially connected to the mounting cavity; the mounting block is provided with an assembly groove, and the locking block is installed in the assembly groove.

[0011] Furthermore, the limiting part includes limiting blocks on both sides of the locking block and limiting grooves on the side wall of the mounting groove that adapt to the limiting blocks. Through the engagement of the limiting blocks and the limiting grooves, the locking block and the mounting block can rotate synchronously.

[0012] Furthermore, the connecting ends of the fixed plate and the seat plate are provided with shaft blocks that contact each other at their ends, and the seat plate and the fixed plate are rotatably connected by a shaft column passing through the shaft blocks.

[0013] Furthermore, the mounting cavity is provided with a mounting groove on its inner side, and a fixing block is installed in the mounting groove. The fixing block and the shaft block are in contact with each other and a snap-fit ​​part is provided between them. When the seat plate is in the first open state, the second open state, or the folded state, the snap-fit ​​part is in the snap-fit ​​state.

[0014] Furthermore, the snap-fit ​​part includes several snap-fit ​​grooves located on the side wall of the fixed block and snap-fit ​​blocks located on the shaft block that are adapted to the snap-fit ​​grooves. After the seat plate rotates, it drives the snap-fit ​​blocks to snap into the corresponding snap-fit ​​grooves.

[0015] Compared with the prior art, the beneficial effects that this utility model can achieve are: This utility model includes a seat panel with a first open state, a second open state, and a folded state: In the folded state, the seat panel is folded up close to the fixed plate, and the two are nearly parallel, occupying less space after folding, making it easy to store; In the first open state, the seat panel in the folded state drives the locking block to rotate clockwise, and the first locking block engages with the locking block and restricts the locking block from rotating counterclockwise, allowing the seat panel to be opened for the baby to sit on; In the second open state, the seat panel in the first open state continues to rotate clockwise, the locking block rotates and releases the locking state of the first locking block, and drives the first locking block to rotate and abut against one side of the second locking block, with the engaging end of the first locking block away from the locking end of the locking block, and the rotating first locking block is locked by the second locking block, at which point the seat panel can be rotated arbitrarily for folding.

[0016] This design allows the seat to be opened for the baby to sit on simply by rotating the seat to a certain angle. When folding is needed, simply continue rotating to a certain angle to unlock the locking mechanism. The seat can be rotated and folded without the need for manual unlocking of the locking unit. The process is simple, convenient, and meets the user's convenience requirements. Attached Figure Description

[0024] 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.

[0025] like Figure 1-6 As shown, a foldable stool core includes a fixing plate 1 for conforming to the mother's abdomen and a foldable seat plate 2. The fixing plate 1 and the seat plate 2 are rotatably connected and can be rotatably opened and closed. The fixing plate 1 has a mounting cavity 3 at one end, and the seat plate 2 is rotatably connected to the mounting cavity 3 at one end. Preferably, the two mounting cavities 3 are located on both sides.

[0026] The mounting cavity 3 is equipped with a locking unit 4. When the seat plate 2 is opened, it is locked by the locking unit 4 to prevent the seat plate 2 from rotating and causing the baby to fall when sitting on it. The locking unit 4 includes a locking block 5, a first engaging block 6, and a second engaging block 7. The locking block 5, the first engaging block 6, and the second engaging block 7 are rotatably mounted in the mounting cavity 3 via a shaft connection. A limiting part 8 is provided between the locking block 5 and the seat plate 2, allowing the locking block 5 to rotate synchronously with the seat plate 2 via the limiting part 8.

[0027] The seat panel 2 includes a first open state, a second open state, and a folded state: the folded state, as shown in the example... Figure 2 As shown, the seat panel 2 folds down to the side of the fixed panel 1, and the two are nearly parallel. After folding, it occupies less space and is easy to store.

[0028] The first open state, such as Figure 3 As shown, when the seat panel 2 is in the folded state, it causes the locking block 5 to rotate clockwise. The first engaging block 6 engages with the locking block 5 and restricts the locking block 5 from rotating counterclockwise, allowing the seat panel 2 to be opened for the baby to sit on. After the locking block 5 causes the first engaging block 6 to rotate slightly counterclockwise, the first engaging block 6 abuts against the upper wall of the mounting cavity 3, preventing the first engaging block 6 from rotating clockwise. This prevents the seat panel 2 from rotating counterclockwise after opening, thus preventing it from closing.

[0029] The second open state, such as Figure 4 As shown, the seat panel 2 in the first open state rotates clockwise continuously. The locking block 5 rotates and releases the locking state of the first locking block 6, and drives the first locking block 6 to rotate and abut against one side of the second locking block 7. The end of the first locking block 6 used for locking is away from the end of the locking block 5 used for locking. The first locking block 6 is locked after rotation by the second locking block 7. At this time, the seat panel 2 can be rotated arbitrarily for folding, and the locking block 5 cannot touch the second locking block 6.

[0030] This design allows the seat panel 2 to be opened for the baby to sit on simply by rotating it to a certain angle. When folding is needed, simply continue rotating it to a certain angle to unlock the locking state. The seat panel 2 can be rotated and folded without the need for manual operation to unlock the locking unit 4. The steps are few, making it convenient to use and meeting the user's convenience requirements.

[0031] The locking block 5 is provided with several consecutive gear parts 9, which lock with the first engaging block 6 through the gear parts 9; when the seat plate 2 is rotated open, the locking block 5 first drives the first engaging block 6 to rotate clockwise to disengage from the current gear part 9, and then the spring rebound force drives the first engaging block 6 to rotate clockwise to engage with the adjacent gear part 9, so that the locking block 5 and the seat plate 2 can only be rotated upward counterclockwise to open, and cannot be rotated downward clockwise to close.

[0032] The first engaging block 6 is provided with a protruding engaging block 10, which is adapted to the gear part 6. The engaging block 10 and the gear part 9 form a limiting position.

[0033] The first locking block 6 is provided with a protruding stop 11. When the locking block 5 drives the first locking block 6 to rotate, the stop 11 pushes the second locking block 7 to rotate until it passes the second locking block 7. The second locking block 7 rotates and resets by the spring force and abuts against one side of the stop 11 for positioning after the first locking block 6 rotates. The locking block 10 moves away from the gear part 9 so that the first locking block 6 is in the unlocked state. At this time, the locking block 5 can rotate arbitrarily and the gear part 9 cannot contact the locking block 10. The folding seat plate 2 can be rotated clockwise downwards.

[0034] When the seat panel 2 is in the second open state, manually rotate the seat panel 2 counterclockwise. At the same time, the locking block 5 rotates counterclockwise. The gear part 9 on the locking block 5 passes over the locking block 10. The locking block 5 continues to rotate counterclockwise until it touches the second locking block 7. The locking block 5 pushes the second locking block 7 to rotate clockwise. The stop block 11 on one side of the second locking block 7 is disengaged from the second locking block 7. At this time, the locking relationship between the first locking block 6 and the second locking block 7 is released. The first locking block 6 and the second locking block 7 are reset by the spring's return force, and the seat panel 2 is in the folded state.

[0035] The first locking block 6 and the second locking block 7 are provided with spring posts 12 at their ends, and the springs are sleeved on the spring posts 12 to prevent the springs from being misaligned.

[0036] The seat plate 2 has a mounting block 13 at one end that is adapted to the mounting cavity 4. The mounting block 13 is axially connected to the mounting cavity 4. The mounting block 13 has an assembly groove 14, and the locking block 5 is installed in the assembly groove 14.

[0037] The limiting part 8 includes limiting blocks 15 on both sides of the locking block 5 and limiting grooves 16 located on the side wall of the assembly groove 14 that are adapted to the limiting blocks 15. The limiting blocks 15 are rectangular or polygonal. Through the engagement of the limiting blocks 15 and the limiting grooves 16, the locking block 5 can rotate synchronously with the mounting block 13 and the seat plate 2.

[0038] The connection between the fixed plate 1 and the seat plate 2 is provided with a shaft block 17 whose ends are in contact with each other, and a rotatable connection is achieved by a shaft column passing through the shaft block 16.

[0039] The mounting cavity 3 has a mounting groove 19 on one side near its inner end. A fixing block 20 is installed in the mounting groove 19, and a spring is also provided in the mounting groove 19 to hold the fixing block 20 in place. The fixing block 20 is in contact with the shaft block 17, and a locking part 21 is provided between them. When the seat plate 2 rotates, it pushes the fixing block 20 to move, and the locking part 21 is engaged. When it rotates to the first open state, the second open state, or the folded state, the fixing block 20 moves due to the spring's rebound force, causing the locking part 21 to be engaged again, increasing the stability of the seat plate 2 after rotation.

[0040] The latching part 21 includes a plurality of latching grooves 22 located on the side wall of the fixed block 20 and a latching block 23 located on the shaft block 17 that is adapted to the latching grooves 22. Preferably, the three latching grooves 22 correspond to the positions of the seat plate 2 in the first open state, the second open state, and the folded state, respectively. After the seat plate 2 is rotated, the latching block 23 is driven to snap into the corresponding latching groove 22 to achieve fixation.

[0041] The seat plate 2 and the fixing plate 1 are provided with a number of evenly distributed hollow parts 18, which reduces material consumption, lowers production costs, and increases breathability.

[0042] The fixing plate 1 is arc-shaped, which can better fit the contour of the abdomen and conforms to ergonomic design.

[0043] 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.
