Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0042] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0043] Next, the changing table and the children's bed in the present application will be elaborated in detail in conjunction with the accompanying drawings and specific embodiments.

[0044] In the prior art, the changing table is fixedly arranged on the children's bed for use. When replacing or repairing the changing table, it is inconvenient to disassemble and assemble, and the function of the changing table in the prior art is single.

[0045] To solve the above - mentioned technical problems, the present application provides a changing table, including a table bottom, a table edge, and a connecting block; the table edge surrounds the periphery of the table bottom; the connecting blocks are oppositely arranged on the table edges on both sides of the table bottom, and the connecting block includes an installation part and a connecting part connected to each other. The installation part is fixedly arranged on the side of the table edge facing the table bottom, and the connecting part is used to detachably connect the changing table to the bracket. Through the setting of the connecting block, the changing table can be detachably installed on the bracket, which is convenient for the disassembly and assembly operations when the changing table is replaced, and the changing table can be detached from the bracket and applied to other usage scenarios, which is convenient to use; by connecting the installation part to the table edge, the stability of the connection can be ensured, and the setting of the connecting part facilitates the disassembly operation of the changing table, with a simple structure and convenient use.

[0046] Refer to Figure 1 、 Figure 2 and Figure 3 In one embodiment, the changing table includes a table bottom 10, a table edge 20, and a connecting block 30. The table edge 20 surrounds the periphery of the table bottom 10, and the table edge 20 and the table bottom 10 cooperate to enclose a space for changing operations (including operations such as changing clothes for children, bathing, changing diapers, etc., which require temporarily placing children). The connecting blocks 30 are oppositely arranged on the table edges 20 on opposite sides of the table bottom 10. By providing the connecting blocks 30, the changing table can be detachably connected to the bracket, which facilitates the disassembly and assembly of the changing table and is convenient to use; the connecting block 30 includes an installation part 31 and a connecting part 32 that are connected to each other. The installation part 31 is fixedly arranged on the table edge 20 (that is, the connecting block 30 is fixedly arranged on the table edge 20), which can ensure the stability of the connection. The connecting part 32 is connected to the bracket, and the structure is simple.

[0047] It should be noted that in some embodiments, the above-mentioned bracket can be the railing 90 of a children's bed (as shown in Figure 14 ). The whole changing table is connected to the railing 90 of the children's bed through the connecting part 32, which facilitates the changing operation of children; in addition, the connecting blocks 30 are oppositely arranged on the table edge 20. In some embodiments, the changing table can be removed from the railing 90 of the children's bed, and the table bottom 10 can be vacated by using the connecting blocks 30 for other purposes. For example, it can be used as a simple storage rack, not limited to this. In this embodiment, the table edge 20 and the table bottom 10 cooperate to enclose a space for changing operations. When in use, the table edge 20 has a blocking effect on children, preventing children from rolling off the table bottom 10, improving the safety of use, and the formed space has a certain accommodating effect. When performing changing operations on children, some utensils (such as diapers, clothes, etc.) are often used, and it can be used to place utensils and has a storage function.

[0048] Refer to Figure 2 、 Figure 5 、 Figure 8 and Figure 9, in one embodiment, the table edge 20 is provided with an installation groove 21, and the installation groove 21 has a straight groove section 211 and an arc groove section 212 connected between adjacent straight groove sections 211. In this embodiment, the installation part 31 has a first installation sub - part 311 and second installation sub - parts 312 arranged at both ends of the first installation sub - part 311. The first installation sub - part 311 is adapted to the straight groove section 211, and the first installation sub - part 311 is inserted into the straight groove section 211. The second installation sub - part 312 is adapted to the arc groove section 212, and the second installation sub - part 312 is inserted into the arc groove section 212. With such a setting, the stability of the installation part 31 can be ensured, that is, the installation part 31 is clamped between the arc groove sections 212 at both ends of the straight groove section 211 through the settings of the first installation sub - part 311 and the second installation sub - part 312, which can ensure the stable and reliable connection between the connecting block 30 and the table edge 20. At the same time, the arc groove sections 212 at both ends of the same straight groove section 211 can position the installation part 31, that is, the installation part 31 can be quickly positioned at its required installation position, improving the production efficiency of the changing table.

[0049] It should be noted that the fixed connection between the installation part 31 and the installation groove 21 can be adhesively bonded through glue such as structural glue, or fixed by screws or rivets, which is not specifically limited here.

[0050] Refer to Figure 1 、 Figure 3 and Figures 8 - 10 , in one embodiment, the connecting block has a first plane perpendicular to the center line of its connecting support pipe section 91 (the pipe section 91 of the children's bed railing 90 in this embodiment, as shown in Figure 14 ). The connecting part 32 is provided with a clamping groove 321 for connecting with the support pipe section 91. At both ends in the length direction of the clamping groove 321 (i.e., the transverse direction in the Figure 9 view, the same below), clamping protrusions 322 are respectively provided. The orthographic projection of the clamping protrusion 322 on the first plane has an arc section, and the central angle corresponding to the arc section is α, satisfying: 195° ≤ α ≤ 285°, such as 195°, 200°, 260°, 285°, etc. In this embodiment, α = 285°. When α is less than 195°, the arc section cannot be well clamped on the pipe section 91 of the railing 90, and the stability of the changing table cannot be ensured. When α is greater than 285°, the contact surface between the arc section and the pipe section 91 of the railing 90 is larger, and a large force is required for the arc section to be clamped on the pipe section 91 of the railing 90, and even the pipe section 91 of the railing 90 cannot be clamped into the arc section. When α is within the above - mentioned value range, it can ensure the smooth clamping of the arc section and the pipe section 91 of the railing 90 while ensuring the stability of the changing table on the railing 90.

[0051] It should be noted that the above-mentioned clamping protrusions 322 are arranged at both ends in the length direction of the clamping groove 321. When the connecting part 32 is connected to the pipe section 91 of the fence 90, only the clamping protrusions 322 at both ends of the clamping groove 321 play a clamping role. That is, the groove walls of the clamping groove 321 between the two clamping protrusions 322 connect the two clamping protrusions 322 into a whole. Such a setting can ensure the stability of the structure of the clamping protrusions 322, that is, ensure the reliability of the connection between the connecting part 32 and the pipe section 91 of the fence 90, and avoid the plastic deformation of the clamping protrusions 322 after multiple disassembly and assembly, which affects the connection quality with the pipe section 91 of the fence 90. And the two clamping protrusions 322 being connected into a whole can ensure that when performing the clamping operation (pressing the washing table down until the clamping protrusions 322 are clamped on the pipe section 91), both ends of the clamping groove 321 perform the clamping operation on the pipe section 91 of the fence 90, improving the installation efficiency. In addition, there is a gap between the groove wall of the clamping groove 321 between the two clamping protrusions 322 and the pipe section 91, avoiding too large a contact surface (i.e., large frictional force) and increasing the difficulty of clamping the clamping protrusions 322 on the pipe section 91.

[0052] In some embodiments, in order to ensure the smooth clamping of the arc segment (clamping protrusion 322) and the pipe section 91, a guiding surface is provided at the end of the arc segment. Through the setting of the guiding surface, the pipe section 91 can be smoothly guided into the arc segment. When installing the washing table on the bracket, due to the settings of the first installation sub - part 311 and the second installation sub - part 312, the connecting block 30 will not displace due to uneven force during installation, improving the installation efficiency of the washing table.

[0053] Refer to Figure 6 and Figure 7 In one embodiment, the washing table further includes a telescopic part 40. One end of the telescopic part 40 is arranged on the periphery of the table bottom 10, and the other end is arranged on the table edge 20. Moreover, the table bottom 10, the telescopic part 40, and the table edge 20 cooperate to enclose a receiving space 41. By adjusting the telescopic part 40 to drive the table bottom 10 and the table edge 20 to approach or move away from each other, that is, through the adjustment of the telescopic part 40, the size of the receiving space 41 can be controlled.

[0054] It should be noted that during use, the telescopic part 40 can be compressed to the minimum. At this time, a washing table similar to Figure 1 is formed. Then, the washing table is connected to the bracket through the connecting block 30 for washing operation. It is also possible to remove the washing table from the bracket and control the size of the receiving space 41 by adjusting the telescopic part 40. For example, Figure 6 as shown, at this time, the washing table can be used as a children's bathtub, with diverse functions and convenient adjustment. In addition, in this embodiment, the material of the telescopic part 40 is a plastic material. In some embodiments, other materials can also be used, not limited to this.

[0055] Refer toFigure 2 , Figure 5 , Figure 6 and Figure 7 In one embodiment, the changing table further comprises two symmetrically arranged U-shaped support legs 50, the support legs 50 comprising two support parts 51 and a stabilizing part 52 connected between the two support parts 51, and the ends of each support part 51 away from the stabilizing part 52 are rotatably arranged on the table edge 20 by a rotating structure 60, so as to adjust the stabilizing part 52 away from or close to the table edge 20. When the changing table is arranged on the bracket for changing and washing operations, the support legs 50 are stored in the mounting grooves 21 of the table edge 20. When the changing table is removed from the bracket for a child's bathing basin, the support legs 50 are unfolded by the setting of the rotating structure 60 to support the changing table, so as to vacate the table bottom 10, and the above-mentioned stabilizing part 52 can stabilize the support legs 50 to ensure the stability of the support; when the child is bathed in this way, the heat of the water will not be discharged due to the contact between the table bottom 10 and the ground (or objects in contact with the table bottom 10 when the changing table is not supported by the support legs 50), so as to prevent the child from catching a cold. In this embodiment, the setting of the support legs 50 is simple in structure and convenient for storage.

[0056] It should be noted that, in some embodiments, a protective pad 70 is provided at the connection between the support portion 51 and the stabilizing portion 52, and the protective pad 70 can protect the supporting legs 50, avoid friction, and increase the service life; at the same time, the protective pad 70 also has an anti-slip effect, ensuring the stability of the changing table when supported by the supporting legs 50. In addition, in some embodiments, the changing table does not have the telescopic portion 40, and the supporting legs 50 can be provided on the table edge 20. The changing table can be removed from the bracket and supported by the supporting legs 50 to be used as a simple storage rack, etc., but is not limited thereto.

[0057] See also Figure 4 and Figures 11 - 13 In one embodiment, the rotating structure 60 includes a positioning block 61, an axial hole 62 disposed on the positioning block 61, and a rotating shaft 63 passing through the axial hole 62, and one end of the supporting portion 51 away from the stabilizing portion 52 is rotatably connected to the rotating shaft 63. The structure is simple and easy to use.

[0058] It should be noted that in some embodiments, the positioning block 61 is provided with a limiting groove 65, and the support portion 51 is rotatably disposed in the limiting groove 65 (such as Figure 11 As shown in FIG. 1 , the bottom of the limiting groove 65 includes a first wall 651, a transition wall 652 and a second wall 653 in sequence. When the supporting leg 50 is not in use, the supporting portion 51 abuts against the first wall 651. At this time, the supporting leg 50 is accommodated in the mounting groove 21 of the table edge 20. When the supporting leg 50 is in use, the supporting portion 51 abuts against the second wall 653, and the second wall 653 is inclined to the lower right ( Figure 13In the perspective), at this time, the two support legs 50 (support parts 51) are in a V shape, and the second wall 653 can ensure the stability of the support part 51 during support. According to the actual use, the angle between the second wall 653 and the vertical plane ( Figure 13 in the perspective) can be adjusted, so as to adjust the included angle between the support leg 50 and the vertical plane during support, so as to ensure the stability of the support of the support leg 50; when the support part 51 rotates from the first wall 651 to the second wall 653 or from the second wall 653 to the first wall 651, the above-mentioned transition wall 652 provides a rotation space for the end of the support part 51, avoiding interference and ensuring smooth rotation.

[0059] Refer to Figure 5 , Figure 11 and Figure 12 , in an embodiment, the positioning block 61 has a first positioning sub-part 611 and a second positioning sub-part 612. The first positioning sub-part 611 is adapted to the straight groove section 211 of the mounting groove 21 and is inserted into the straight groove section 211, and the second positioning sub-part 612 is adapted to the arc groove section 212 of the mounting groove 21 and is inserted into the arc groove section 212. With such a setting, the installation position of the positioning block 61 can be quickly positioned, and the positioning block 61 is fixed in the mounting groove 21 through the fixing hole 64 on the positioning block 61; in addition, with such a setting, when the support leg 50 supports the main body of the changing table, the arc groove section 212 has a limiting effect on the positioning block 61, and the positioning block 61 will not move due to the extrusion of the support leg 50, thereby ensuring the stability of the support.

[0060] Refer to Figure 6 and Figure 7 , in an embodiment, the changing table further includes a frame 80 laid on the side of the table edge 20 away from the connecting block 30.
