Description

[Technical Field]

[0001] This utility model relates to an infant care device. [Background Technology]

[0002] Baby care devices are common products for infant care. After attaching a cloth cover to the device, the baby can be placed inside for diaper changes or wiping. Traditional baby care devices are generally unfoldable or foldable; when unfolded, they can be used for infant care, and when folded, they are easy to store and take up less space. Currently, baby care devices on the market have various structures and folding principles. Therefore, this invention provides a novel baby care device that differs from existing technologies. [Utility Model Content]

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a baby care device with a simple structure, convenient folding operation, and smooth folding.

[0004] This utility model is achieved through the following technical solution:

[0005] An infant care device includes two first support rods spaced apart from each other and two second support rods spaced apart from each other. The second support rods intersect with the first support rods on the same side and are rotatably connected at the intersection. A folding assembly is provided between the first and second support rods to fold or unfold them. The folding assembly includes a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably connected to the first support rod, and the other end of the first connecting rod is rotatably connected to the second connecting rod. The end of the second connecting rod away from the first connecting rod is rotatably connected to the second support rod. A locking structure is provided at the connection position between the first and second connecting rods to lock the first and second support rods in the unfolded state. The locking structure includes a locking piece connected to the first connecting rod and capable of lateral movement relative to it. The locking piece is provided with a hook that can engage or disengage with the second connecting rod when it moves laterally. A return spring is provided between the locking piece and the first connecting rod to push the locking piece to move and reset.

[0006] The first connecting rod has a long strip-shaped structure. A horizontally extending fixing plate is provided on the first connecting rod and at one end connected to the second connecting rod. The locking plate is located below the fixing plate and is connected to the first connecting rod by a rivet with a convex cap. The upper surface of the locking plate abuts against the lower surface of the fixing plate so that the fixing plate can prevent the locking plate from rotating. One end of the return spring abuts against the convex cap, and the other end abuts against the side of the first connecting rod.

[0007] The first connecting rod is provided with a through hole, and the locking piece is fixedly connected to the rivet so that the rivet can slide in the through hole.

[0008] The second link is a long strip-shaped sheet structure. The locking piece includes a sheet-shaped body. The hook is set on the body and bent to one side of the body to be integrally formed with the body. When the locking structure is locked, the hook hooks onto the lower side of the second link.

[0009] The hook is provided with an inclined surface 6 that can press against the upper edge of the second connecting rod when the first and second support rods are unfolded, thereby causing the locking piece to move laterally.

[0010] The first connecting rod and the fixing plate are integrally bent into a single structure.

[0011] A support frame that can be unfolded or folded relative to the two second support rods is rotatably connected between them. The support frame includes a U-shaped frame body, and the two ends of the frame body are respectively rotatably connected to the corresponding second support rods. A transmission plate is also rotatably connected to the second support rod. The transmission plate is provided with a strip groove. The frame body is provided with a sliding column that can slide in the strip groove when it is unfolded or folded.

[0012] Multiple transverse first connecting rods 6 are provided between the two first support rods, multiple transverse second connecting rods 6 are provided between the two second support rods, and a transverse third connecting rod is also provided on the frame.

[0013] The first support rod is formed by connecting a first lower support rod, a first middle support rod, and a first upper support rod. The first middle support rod includes a first flat section and first circular tube sections at both ends of the first flat section. The first lower support rod and the first upper support rod are both circular tube structures and are inserted into the corresponding first circular tube sections. The second support rod is formed by connecting a second lower support rod, a second middle support rod, and a second upper support rod. The second middle support rod includes a second flat section and second circular tube sections at both ends of the second flat section. The second lower support rod and the second upper support rod are both circular tube structures and are inserted into the corresponding second circular tube sections. The first flat section and the second flat section intersect each other and are rotatably connected at the intersection position.

[0014] The first and second central support rods are both made of round tubes and flattened in the middle of the tubes. A plastic gasket 7 is provided between the first flat section and the second flat section.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. When this baby care device needs to be folded, simply move the locking plate horizontally to disengage the hook on the locking plate from the second connecting rod. The first and second connecting rods rotate relative to each other and move upwards. The other end of the first connecting rod rotates relative to the first support rod, and the other end of the second support rod rotates relative to the second support rod. Thus, the first and second supporting rods are pulled together by their relative rotation, achieving the folding of the baby care device. The entire folding operation is very convenient, quick, and smooth. When unfolding is needed, simply move the first and second support rods to the sides to rotate relative to each other. The first and second connecting rods also rotate relative to each other to unfold the device. Finally, the hook on the locking plate hooks onto the second connecting rod again to lock it in place. The entire baby care device has a simple structure, and the folding and unfolding operations are convenient and smooth, making it suitable for widespread application.

[0017] 2. The second support rod of this utility model is also connected to an unfoldable or foldable support frame. When unfolded, the support frame can be used for drying clothes, etc. When the support frame is unfolded, the sliding column is located at the lower end of the strip groove, thereby keeping the support frame in a relatively horizontal position. When the support frame needs to be folded, simply lift the support frame upwards, the sliding column slides and rotates upwards in the strip groove, the transmission plate rotates relative to the second support rod, and finally the support frame moves closer to the second support rod. At this time, the baby care device can be placed against the wall and the support frame can be placed against the wall to facilitate the storage of the folded baby care device and also prevent the support frame from unfolding.

Detailed Implementation Methods

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figure 1 , Figure 3 , Figure 8 and Figure 9 As shown, an infant care device includes two first support rods 1 spaced apart from each other and two second support rods 2 spaced apart from each other. The second support rods 2 intersect with the first support rods 1 on the same side and are rotatably connected at the intersection. Multiple transverse first connecting rods 61 are provided between the two first support rods 1, and multiple transverse second connecting rods 62 are provided between the two second support rods 2, thereby forming a stable frame structure. The first support rods 1 and the second support rods 2 are rotatably connected to each other, and their lower ends are supported on the ground, so that the entire infant care device can be folded or unfolded like scissors.

[0029] like Figure 1 and Figure 3 As shown, in order to achieve smooth folding and unfolding, and to reliably lock after unfolding, a folding assembly 3 is provided between the first support rod 1 and the second support rod 2 to pull the two to fold or unfold. The folding assembly 3 includes a first connecting rod 31 and a second connecting rod 32. The first connecting rod 31 has a long strip-shaped structure and one end is rotatably connected to the first support rod 1. The other end of the first connecting rod 31 is rotatably connected to the second connecting rod 32. The second connecting rod 32 also has a long strip-shaped structure, and the end of the second connecting rod 32 away from the first connecting rod 31 is rotatably connected to the second support rod 2.

[0030] like Figure 1 , Figure 3 and Figure 6As shown, in order to ensure the safe use of the baby care device in the unfolded state and prevent accidental folding, a locking structure 4 is provided at the connection position between the first link 31 and the second link 32 to lock the first support rod 1 and the second support rod 2 in the unfolded state. The locking structure 4 includes a locking piece 41 connected to the first link 31 and capable of moving laterally relative to it. The locking piece 41 is provided with a hook 42 that can engage or disengage with the second link 32 when it moves laterally. A return spring 43 is provided between the locking piece 41 and the first link 31 to push the locking piece 41 to move and reset. When the baby care device needs to be folded, simply move the locking piece 41 horizontally to disengage the hook 42 on the locking piece 41 from the second connecting rod 32. The first connecting rod 31 and the second connecting rod 32 rotate relative to each other and move upward. The other end of the first connecting rod 31 rotates relative to the first support rod 1, and the other end of the second support rod 32 rotates relative to the second support rod 2. Thus, the first support rod 1 and the second support rod 32 are pulled together by the first connecting rod 31 and the second connecting rod 32, thus realizing the folding of the baby care device. The entire folding operation is very convenient and quick, and the folding is also very smooth.

[0031] like Figure 6 and Figure 7 As shown, in this embodiment, a laterally extending fixing piece 33 is provided on the first connecting rod 31 and at one end connected to the second connecting rod 32. The fixing piece 33 and the sheet-like first connecting rod 31 are integrally bent into a single structure. The locking piece 41 includes a sheet-like body 411, and the hook 42 is provided on the body 411 and bent to one side of the body 411 to be integrally formed with the body 411. Specifically, the locking piece 41 is located below the fixing piece 33. The first connecting rod 31 is provided with a through hole 34, and a rivet 45 passes through the through hole 34 and is fixedly connected to the first connecting rod 31. The head of the rivet 45 is provided with a protruding cap 44. Since the rivet 45 is fixed to the locking piece 41, and the rivet 45 can slide in the through hole 34, the locking piece 41 can move laterally relative to the first connecting rod 31 together with the rivet 45. Meanwhile, the upper surface of the locking piece 41 abuts against the lower surface of the fixing piece 33, which acts as a guide and limiter, effectively preventing the locking piece 41 from rotating during movement. The return spring 43 is located between the locking piece 41 and the first connecting rod 31. The return spring 43 is fitted onto the rivet 45, with one end abutting against the convex cap 44 of the rivet 45 and the other end abutting against the side of the first connecting rod 31. In the unfolded state of the baby care device, the return spring 43 is in an extended state, providing a force to keep the hook 42 engaged with the second connecting rod 32. When the locking structure 4 is locked, the hook 42 engages with the lower side of the second connecting rod 32.

[0032] like Figure 3 , Figure 6 and Figure 7As shown, when the first support rod 1 and the second support rod 2 move from the folded state to the unfolded state, the first connecting rod 31 and the second connecting rod 32 gradually straighten. When nearly fully unfolded, the hook 42 on the locking plate 41 contacts the upper edge of the second connecting rod 32. To guide the hook 42 smoothly into the locking position, the hook 42 has a ramp 46, which presses against the upper edge of the second connecting rod 32, overcoming the elastic force of the return spring 43, forcing the locking plate 41 to move laterally backward. When the device is fully unfolded, and the first connecting rod 31 and the second connecting rod 32 are in a straight line or nearly straight line, the locking plate 41 quickly returns to its original position under the push of the return spring 43, and the hook 42 follows the movement of the locking plate 41 and hooks the lower side of the second connecting rod 32 (e.g., ...). Figure 3 (As shown), thus locking the entire device in the unfolded state and preventing it from folding accidentally.

[0033] like Figure 1 and Figure 2 As shown, to further enhance the functionality of the baby care device, a support frame 5 that can be unfolded or folded is rotatably connected between the two second support rods 2. When unfolded, the support frame 5 can be used for drying clothes or other items. The support frame 5 includes a U-shaped frame body 51, with both ends of the frame body 51 rotatably connected to the corresponding second support rod 2 via pins. A transmission plate 52 is also rotatably connected to the second support rod 2, and the transmission plate 52 has a strip groove 53. The frame body 51 is provided with a sliding column 54 that can slide within the strip groove 53 when unfolded or folded. When the support frame 5 needs to be folded, simply pull the frame 51 upwards. The sliding column 54 slides upwards within the strip groove 53 and rotates relative to the transmission plate 52. The transmission plate 52 rotates relative to the second support rod 2, and finally the support frame 5 moves closer to the second support rod 2. At this time, the baby care device can be placed against the wall, and the support frame 5 can be placed against the wall to facilitate storage of the folded baby care device and prevent the support frame 5 from unfolding. Of course, a snap-fit ​​hook structure can also be provided between the frame 51 and the second support rod 2 to prevent the support frame 5 from unfolding in the folded state. However, for the baby care device in this embodiment, its folded state is generally placed against the wall, so providing a snap-fit ​​hook structure is not very necessary. In this embodiment, the frame 51 is also provided with a transverse third connecting rod 55 to increase the structural strength of the support frame 5. When the support frame 5 is unfolded, the sliding column 54 is positioned at the lower end of the strip groove 53 to make the support frame 5 in a relatively flat support state.

[0034] like Figure 1 and Figure 5As shown, for ease of production, transportation, and packaging, both the first support rod 1 and the second support rod 2 adopt a segmented structure. The first support rod 1 is formed by connecting the first lower support rod 11, the first middle support rod 12, and the first upper support rod 13. The first middle support rod 12 is formed by flattening a section of round tube in its middle, creating a first flat section 121, while the two ends of the first flat section 121 retain the original first round tube sections 112. The first lower support rod 11 and the first upper support rod 13 are both standard round tube structures, which can be inserted into the first round tube sections 112 at both ends of the first middle support rod 12 and fixed by tight fit, pins, or screws. Similarly, the second support rod 2 is formed by connecting the second lower support rod 21, the second middle support rod 22, and the second upper support rod 23. The second middle support rod 22 is also formed by flattening a round tube to create a second flat section 221, while the two ends retain the second round tube sections 222. The second lower support rod 21 and the second upper support rod 23 are round tubes and are inserted and fixed to the second round tube sections 222. The intersection and rotation connection point of the first support rod 1 and the second support rod 2 is located at the intersection of the first flat section 121 of the first middle support rod 12 and the second flat section 221 of the second middle support rod 22. A plastic gasket 7 is also added between the first flat section 121 and the second flat section 221, which can reduce friction and noise between metal parts, and also provide a certain amount of damping, so that the user can fold or unfold the baby care device smoothly and comfortably.

[0035] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
