Description

Technical Field

[0001] This technical solution relates to the field of bathing products technology, specifically to a support and adjustment device, a children's bathtub, and a children's bath stand. Background Technology

[0002] A bathtub is a bathing device that holds water for human body cleaning. Children's bathtubs are specially designed for infants and toddlers, equipped with a non-slip base and rounded edges to ensure safety. Some products are adjustable to fit different age groups, helping parents easily complete baby cleaning and care in the home environment, combining practicality and comfort.

[0003] For example, Chinese patent CN202426399U discloses an improved structure of a children's bathtub, which mainly consists of a basin, a soft pillow, and a seat cushion. The inner wall of the head end of the basin is a sloping surface that conforms to the curve of a child's back. When in use, water is added to the basin, the water temperature and water level are adjusted, and then the child is placed in the basin with their buttocks on the seat cushion, their back pressed against the sloping surface of the basin, and their head placed on the soft pillow.

[0004] Existing children's bathtubs generally use a fixed backrest structure, which is difficult to adapt to the changes in the body posture of infants and young children at different growth stages (such as newborns needing to lie down for support, and older infants gradually gaining the ability to sit up). Because the angle of traditional bathtubs is not adjustable, it is easy to cause problems such as insufficient support during bathing, resulting in slipping, and discomfort causing fatigue. Caregivers need to lift and adjust the baby's position for a long time, which is laborious and inconvenient to use, and needs to be improved. Summary of the Invention

[0005] This technical solution aims to address the problems of insufficient support and difficulty in adjusting body position caused by the fixed backrest of existing children's bathtubs, which cannot adapt to the changes in the body posture of infants and young children during their growth stages, thus making them inconvenient to use. It provides a support adjustment device, a children's bathtub, and a children's bath frame.

[0006] The purpose of this technical solution is achieved as follows:

[0007] A support adjustment device, comprising:

[0008] Support leg one, used for hinged connection with the support plate;

[0009] Support leg two is slidably fitted relative to support leg one, and support leg one and support leg two can extend or retract relative to each other;

[0010] A locking structure is disposed between the first support leg and the second support leg; the locking structure can switch between a locked state and an unlocked state; when the locking structure is in the unlocked state, the locking structure disengages from the first support leg or the second support leg; when the locking structure is in the locked state, the locking structure locks the first support leg and the second support leg.

[0011] Through the above technical solution, when a children's bathtub is in normal use, the support mechanism of the backrest can flexibly adjust the backrest angle by hinged at one end of support leg one and slidingly engaging with support leg two at the other end. When the fixed position structure is in the unlocked state, support leg one and support leg two can freely extend and retract along the sliding trajectory to adjust the different support heights on the seat, thereby adapting to different body postures of infants and young children. After adjusting to the desired position, the fixed position structure is switched to the locked state to fix the relative positions of support leg one and support leg two, forming a stable support effect. Through the coordinated cooperation of sliding extension and fixed position locking, the operation steps of adjusting the backrest angle of the bathtub are simplified, the adaptability and comfort of body position support during bathing are improved, and the use is more convenient.

[0012] Preferably, the grading structure includes:

[0013] A button, which is hinged to the first support leg, has a snap-fit ​​part protruding from one end of the button;

[0014] The slot is located on the side of the second support foot near the button. The slot includes multiple snap-fit ​​slots, which are spaced apart along the sliding direction of the first support foot and the second support foot.

[0015] The elastic element acts on the button to rotate around the hinge axis, causing the locking part to tend to fit into the locking groove. The locking part can fit into different locking grooves.

[0016] With the above technical solution, when the backrest angle needs to be adjusted, press the button to make it rotate around the hinge axis. At this time, the locking part at the other end overcomes the elastic force of the elastic element and disengages from the current locking groove, and the positioning structure is in the unlocked state. Support leg one and support leg two can freely extend and retract along the sliding direction. Pull support leg one and support leg two to the appropriate length, release the button, and the elastic element pushes the locking part to automatically embed into the other locking groove selected at the corresponding sliding position, realizing multi-position locking. This design, through the linear operation logic of press-slide-release, allows for quick adjustment by one hand blindly. The interval layout of the multi-level locking grooves ensures accurate positioning of each position during the extension and retraction of the support leg, and has multi-position adjustment and elastic self-locking mechanism, improving the smoothness of adjustment and the stability of locking, further improving the convenience of operation.

[0017] Preferably, a mounting groove is provided on one side wall of the support foot, and the button is hinged in the mounting groove. A backing plate is formed at the bottom of the mounting groove. One end of the elastic member abuts against the backing plate, and the other end abuts against the end of the button away from the snap-fit ​​part.

[0018] Through the above technical solution, the button is embedded in the mounting groove to reduce the volume of exposed parts. One end of the elastic element abuts against the abutting plate at the bottom of the mounting groove, and the other end abuts against the end of the button away from the snap-fit ​​part, forming a stable lever-type elastic reset structure and improving the elastic force transmission efficiency.

[0019] Preferably, the abutment plate has a positioning protrusion, the button has a corresponding positioning block, the positioning block has a positioning groove, one end of the elastic element is sleeved on the positioning protrusion, and the other end is embedded in the positioning groove.

[0020] By using the above technical solution, one end of the elastic element is embedded in the positioning slot, and the other end is aligned with the positioning protrusion and fitted in, thus completing the installation of the elastic element, preventing the elastic element from falling off or shifting, and improving the stability and reliability of the elastic element in long-term use.

[0021] Preferably, each of the snap-fit ​​grooves has a positioning surface one, and the inner wall of the snap-fit ​​groove facing the support foot one has a positioning surface one. The inclination direction of the positioning surface one causes the snap-fit ​​groove to gradually widen away from the support foot two from the bottom of the groove to the opening of the groove.

[0022] The end of the snap-fit ​​part has a second positioning surface, which matches the first positioning surface, and the second positioning surface and the first positioning surface form a surface abutment positioning.

[0023] Through the above technical solution, based on the matching of the tilt direction and angle of positioning surface one and positioning surface two, the end shape of the snap-fit ​​part matches the flared snap-fit ​​groove. The contact between positioning surface two and positioning surface one guides the insertion into the positioning groove, making the fitting operation more convenient and improving the fitting accuracy.

[0024] Preferably, the first support leg has a cavity, and the first support leg has a mounting port connected to the cavity, and the second support leg is embedded into the cavity through the mounting port;

[0025] The second support leg has a limiting part that protrudes from the side of the second support leg away from the slot. The first support leg has a corresponding limiting groove. The limiting part is limited to moving within the limiting groove to limit the maximum distance between the first support leg and the second support leg.

[0026] Through the above technical solution, the first support leg is slidably connected to the second support leg by embedding it into the cavity and the mounting port. The limiting part of the second support leg moves along a fixed trajectory in the limiting groove of the first support leg. When the limiting part moves to the limit position against the side wall of the limiting groove, the stroke is terminated. By limiting the maximum distance of the two relative extensions, the stability and reliability of the structure are ensured.

[0027] A children's bathtub includes a basin body and a support adjustment device as described in any of the above claims. The basin body is provided with a support plate, the support plate is hinged to the basin body, and the support adjustment device is disposed on the rear side of the support plate.

[0028] With the above technical solution, the support leg is hinged to the support plate, and the support plate can be flexibly adjusted to fit the spine according to the infant's body shape. The support mechanism realizes the independent adjustment function of the backrest angle.

[0029] Preferably, the support plate is provided with an extension strip, the extension strip has a hinge block, the hinge block has a through hinge hole, and each support foot has a relief groove corresponding to the hinge block. Each relief groove has a hinge post protruding along the opposite inner wall, and the hinge posts on both sides are respectively embedded into the through openings at both ends of the hinge hole.

[0030] The support plate is provided with a limiting block, which is located on one side of the support plate along the rotation direction of the first support foot, and is used to limit the maximum rotation angle of the first support foot.

[0031] Through the above technical solution, the support plate is integrally formed with an extension strip, which transforms the hinged back panel, which may have previously only been hinged to the adjustment component at a single point or a few points, into a line hinge by means of the extension strip. This increases the strength of the hinge point, disperses the pressure of a person leaning against the support plate, prevents the support plate from deforming, and thus improves the stability and durability of the support.

[0032] Once the limiting block of the support plate contacts the support foot, it limits the maximum rotation angle around the hinge point, ensuring that the adjustment process is always within the safe threshold, avoiding mechanism jamming or structural damage caused by excessive stretching or rotation, making the adjustment process more intuitive and controllable.

[0033] A children's bath frame includes a frame body and a support adjustment device as described in any of the preceding claims. The frame body has a support plate, and the support adjustment device is disposed on the rear side of the support plate.

[0034] Through the above technical solution, the support mechanism set on the rear side of the support plate adjusts its tilt angle through the telescopic linkage of support leg one and support leg two, thereby adjusting the overall height and tilt angle of the bathtub rack.

[0035] Preferably, the first support leg has a hinge portion, and there are two hinge portions. The two hinge portions are located at the end of the first support leg near the support plate, and the two hinge portions are symmetrically distributed on both sides of the first support leg along the hinge axis. The outer edge of the frame is provided with a flange portion, and the two hinge portions are hinged to the two sides of the flange portion respectively.

[0036] Through the above technical solution, the hinged parts on both sides of the upper end of the support foot are hinged to the opposite sides of the flange, which can be achieved by the flange having through holes or slots, thereby improving the strength and stability of the rotational structure between the support foot and the base.

[0037] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0038] 1. This technical solution achieves linear operation of quick unlocking, sliding adjustment, and self-locking by hinged support foot one to the seat body, sliding cooperation between support foot two and support foot one, and the coordinated action of the fixed position structure. It dynamically adapts to the changes in the growth posture of infants and young children, ensuring flexible adjustment and stable support of the backrest angle, while improving the comfort of the washing and care position and the convenience of operation.

[0039] 2. This technical solution uses an integrally formed support plate with an extension strip. The hinge block on the extension strip is hinged to the support foot, optimizing the single-point hinge into a linear hinge structure, and distributing the pressure to the entire extension strip.

[0047] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0048] Example:

[0049] See Figure 1A children's bathtub includes a basin body 1, which can be filled with water. The basin body 1 is provided with a support plate 6, the lower end of which is hinged to one end of the basin body 1 along the length direction, and the hinge axis is set in the horizontal direction. A flexible connecting part 30 is integrally connected between the support plate 6 and the basin body 1. The flexible connecting part 30 is made of a flexible and deformable material (such as rubber) and is formed on both sides of the support plate 6 and the side of the basin body 1. When the support plate 6 rotates around the hinge, the flexible connecting part 30 can deform accordingly, while ensuring the sealing of the hinge position between the support plate 6 and the basin body 1, and has a good rotation effect. The support plate 6 can be folded into the basin body 1.

[0050] See Figure 2 and Figure 3 A support adjustment device includes a first support leg 21, a second support leg 22, and a fixing structure 23. The first support leg 21 is hinged to a support plate 6, and its hinge axis is parallel to the hinge axis between the support plate 6 and the basin 1. The specific hinge method is as follows: an extension strip 7 is formed protruding from the back of the support plate 6. In this embodiment, two extension strips 7 are shown. The two extension strips 7 are arranged in parallel and their length directions are both perpendicular to the hinge axis between the support plate 6 and the basin 1. Each extension strip 7 is integrally formed with a hinge block 8, which is located at the middle position of the corresponding extension strip 7. Each hinge block 8 has a through hinge hole 9.

[0051] Correspondingly, the support foot 21 has two relief grooves 10 at the positions of the two hinge blocks 8. Each relief groove 10 has a hinge protrusion on the opposite side wall corresponding to the hinge axis of the support foot 21. During assembly, the two hinge blocks 8 are embedded into the two relief grooves 10, so that the two hinge protrusions in each relief groove 10 are embedded into the opposite ends of the hinge hole 9, thereby improving the strength of the hinge point and forming a stable hinge structure.

[0052] Support leg 22 slides relative to support leg 21. Support leg 21 has a cavity 24, and a mounting port 25 is connected to the cavity 24. The mounting port 25 is located at the end of support leg 21 away from support plate 6. The mounting port 25 is adapted to support leg 22, so that the upper end of support leg 22 is inserted into the cavity 24 through the mounting port 25. Support leg 22 has a limiting part 26, which protrudes from the end face of support leg 22 facing the inner wall of the cavity 24. Adjusting support leg 21 to the corresponding opening A limiting groove 27 is provided, and a limiting part 26 is embedded in the limiting groove 27 and moves along the groove. When the first support leg 21 slides relative to the second support leg 22, the limiting protrusion moves along the limiting channel to change its position. When the second support leg 22 is embedded in the cavity 24 until it can no longer be fitted, it is at the minimum distance between the two support legs. When the limiting part 26 abuts against the inner wall of the limiting groove 27 on the side opposite to the through end, it is used to limit the maximum distance between the first support leg 21 and the second support leg 22.

[0053] The support plate 6 is provided with a limiting block 28, which is fixed to the back of the support plate 6 and located on the upper side of the support plate 6 along the rotation direction of the support foot 21. It is used to abut against the support foot 21 to limit the maximum rotation angle of the support foot 21 relative to the seat.

[0054] The second support foot 22 is also provided with a rubber pad 29. In this embodiment, it is shown to be installed on the side end face of the second support foot 22 away from the first support foot 21 and to be fitted and installed with the second support foot 22. It is used to contact the ground, increase friction, and improve support stability.

[0055] See Figure 3 and Figure 4 The positioning structure 23 includes a button 231, a slot 232, and an elastic element 233. The support foot 21 is provided with a mounting groove 14, which passes through the side wall of the mounting groove 14. The button 231 is embedded in the mounting groove 14. The button 231 is hinged in the mounting groove 14 through the hinge structure on both sides, realizing its hinge with the support foot 21. The hinge axis is parallel to the hinge axis between the support foot 21 and the support plate 6. The bottom of the mounting groove 14 is formed with a backing plate 15. The backing plate 15 protrudes into the mounting groove 14 with a positioning protrusion 16. The button 231 is provided with a positioning block 17 corresponding to the positioning protrusion 16. It protrudes from the end face of the button 231 facing the positioning protrusion 16. A positioning slot 18 is formed on its inner side. The elastic element 233 is preferably a return spring. One end of the elastic element 233 is embedded in the positioning slot 18, and the other end is sleeved on the positioning protrusion 16 and abuts against the backing plate 15 to realize bidirectional positioning.

[0056] The slot 232 is located on the end face of the second support foot 22 near the button 231. It includes multiple locking slots 5, which are spaced apart along the sliding direction of the first support foot 21. Each locking slot 5 has a positioning surface 19, which is set as the inner sidewall of the locking slot 5 near the first support foot 21. The inclination direction of the positioning surface 19 causes the corresponding locking slot 5 to gradually widen away from the second support foot 22 from the bottom to the opening, and to flare outward. The end of the locking part 4 has a corresponding positioning surface 20. The inclination direction and angle of the positioning surface 20 are matched with each positioning surface 19. The elastic force of the elastic member 233 acts on the button 231 to make it rotate around the hinge axis, so that the locking part 4 has a tendency to fit into the locking slot 5. The positioning surface 19 and the positioning surface 20 form a surface contact lock, so that the positioning part can fit into different positioning slots and support the first support foot 21 and the second support foot 22 with different support lengths.

[0057] The specific work process of this plan is as follows:

[0058] This technical solution uses the double extension strips 7 on the back of the support plate 6 to hinge the first support leg 21. The second support leg 22 forms a sliding pair with the limiting groove 27 of the first support leg 21 through the limiting part 26. During operation, pressing the button 231 overcomes the spring force of the return spring, causing the locking part 4 of the button 231 to disengage from the locking groove 5 of the second support leg 22. At this time, the second support leg 22 can be pulled along the sliding direction to the target position (the adjustment range is constrained by the length of the limiting groove 27). After releasing the button 231, the elastic force of the elastic element 233 pushes the locking part 4 and the corresponding locking groove 5 to form a slope self-locking, ensuring the stability of the support. The maximum unfolding angle of the support plate 6 is mechanically limited by the back limiting block 28. Pressing the button 231 again will release the locking. Through the coordinated cooperation of sliding extension and fixed locking, the operation steps of adjusting the bathtub backrest angle are simplified, the adaptability and comfort of body position support during washing and care are improved, and the use is more convenient.

[0059] See Figure 5 and Figure 6 A children's bath frame for reclining use, which can be placed in a children's bathtub or used alone, includes a frame body 2 with a water hole for drainage. The frame body 2 has a support plate 6, which is set on the back end face of the frame body 2. A support leg is hinged to the back of the frame body 2. Specifically, the support leg has a hinge part 12 near the upper end of the frame body 2, which includes two hinge parts 12, and the two hinge parts 12 are symmetrically distributed on both sides of the support leg 21 along the hinge axis. The outer edge of the frame body 2 is provided with a flange 13, and the two hinge parts 12 are hinged to the two sides of the flange 13 respectively. Specifically, the flange 13 can be provided with through holes for fitting the hinge parts 12, or the flange 13 can have a connecting protrusion protruding on the inner side near the hinge part 12, and the inner side of the connecting protrusion has a connecting groove, and the hinge part 12 is embedded in the connecting groove to achieve hinge.
