Description

Technical Field

[0001] This application relates to the field of infant care technology products, and in particular to a rod-connecting structure and a diaper changing table. Background Technology

[0002] A changing table is a tool specifically designed for infant care. Its core structure includes a support platform with safety railings, on which a changing table is mounted for daily infant care. Some models also come with casters. Its main function is to provide parents with an ergonomic standing height for efficient diaper changing, clothing arrangement, and body cleaning, significantly reducing back strain from frequent bending. As a result, it has gained increasing popularity and application.

[0003] Currently, the most common types of baby changing tables on the market are folding and fixed. Folding changing tables generally have an X-shaped folding structure, which makes them easy to fold and takes up little space when stored. However, the support frame is relatively thin, so it lacks stability. Fixed changing tables are more stable than folding changing tables, but they require more storage space when not in use.

[0004] Regarding the aforementioned technologies, for manufacturers, the folding changing table, being a single unit, has a larger volume in its packaging, resulting in higher transportation costs. On the other hand, while fixed changing tables can be disassembled into smaller units for packaging and transport, reducing transportation costs, their support frames are mostly composed of assembled rods. Assembly requires corner pieces, sleeves, and other connectors, meaning consumers need to use screwdrivers and other specialized tools to install the various components and connectors, making the process cumbersome and increasing the difficulty of use for consumers. Utility Model Content

Detailed Implementation

[0024] The present application will be further described in detail below with reference to all the accompanying drawings.

[0025] The first aspect of this application provides a rod connection structure. Example

[0026] Reference Figures 1 to 4A rod-joint connection structure is disclosed to enable quick assembly and disassembly between two rods (a vertical first rod 100 and a horizontal second rod 200), particularly suitable for connecting furniture products such as baby changing tables. The rod-joint connection structure includes a support member 1 and a connector 2. The support member 1 is fixedly connected to the side wall of the first rod 100. The support member 1 includes a first connecting portion 11 and at least one supporting portion 12. In this embodiment, one supporting portion 12 is used as an example. The support portion 12 is integrally connected to one side of the first connecting portion 11. The support portion 12 has a first slot 121 extending along the axis of the first rod 100. The opening of the first slot 121 faces upward. The other side of the first connecting portion 11 is provided with an abutment portion 111 that cooperates with the side wall of the first rod 100. The abutment portion 111 can be a flat surface, an arc-shaped concave surface, or an arc-shaped convex surface, and is designed to match the shape of the outer side wall of the first rod 100. In this embodiment, the cross-section of the first rod 100 is an elliptical tube, the abutment portion 111 is an arc-shaped concave surface, and the first connecting portion 11 is set as an arc-shaped plate. The first connecting portion 11 and the side wall of the first rod 100 are fixedly connected by fasteners. The setting of the abutment portion 111 makes the connection between the first connecting portion 11 and the first rod 100 more compact and firm. In this embodiment, it is preferred to fix it with a rivet connection. In another embodiment, the first connecting part 11 is a cylindrical body that is fitted onto the outside of the first rod 100. Its inner sidewall forms an abutment part 111 that mates with the outer wall of the first rod 100, wrapping the sidewall of the first rod 100 and connecting it to the first rod 100 by means of rivets.

[0027] Furthermore, the number of connectors 2 is equal to and corresponds one-to-one with the number of support parts 12. Each connector 2 includes a second connecting part 21 and a connector 22. The end of the second connecting part 21 away from the connector 22 is provided with a connecting hole 211. The end of the second rod 200 is inserted into the connecting hole 211. A fastener is used to achieve a fixed connection between the connector 2 and the second rod 200; in this embodiment, a rivet fixing method is preferred. The connector 22 is integrally connected to the end of the second connecting part 21 away from the second rod 200. The connector 22 has a radially downward protruding first insert 221 that matches the shape and size of the first slot 121. During assembly, the first insert 221 is aligned with the first slot 121 and inserted downwards to achieve the connection between the connector 2 and the support part 1, thereby enabling rapid assembly of the first rod 100 and the second rod 200 in the vertical direction without the need for screwdrivers or other tools.

[0028] Reference Figure 2Furthermore, to improve the connection strength between the connector 2 and the support 1, a through groove 122 communicating with the first slot 121 is provided on the side wall of the support 12 away from the first connecting part 11. The groove wall of the through groove 122 is offset from the groove wall of the first slot 121, forming a stepped surface facing the first connecting part 11. Correspondingly, a snap-fit ​​block 222 adapted to the shape and size of the through groove 122 is integrally provided on the first insert 221. When the first insert 221 is inserted into the first slot 121 to the bottom, the snap-fit ​​block 222 simultaneously snaps into the through groove 122 and is limited by the stepped surface to prevent the connection structure from loosening.

[0029] Reference Figure 3 and Figure 4 Furthermore, a support protrusion 123 is provided on the side wall of the support portion 12 away from the first connecting portion 11. A stop block 223 is integrally connected to the side of the snap-fit ​​block 222 away from the first insert block 221. The stop block 223 is provided with a support groove 224 that matches the shape and size of the support protrusion 123. The support protrusion 123 is U-shaped. In order for the support protrusion 123 to be smoothly inserted into the support groove 224 during assembly, the support groove 224 penetrates through the bottom of the first insert block 221. When the first insert block 221 is fully inserted into the first slot 121, the support protrusion 123 is embedded in the support groove 224, which further enhances the stability and torsional resistance of the connection.

[0030] Reference Figure 4 A positioning hole 112 is provided on the side of the first connecting part 11 facing the supporting part 12, and a positioning protrusion 212 corresponding to the positioning hole 112 is provided on the end face of the second connecting part 21 away from the connecting insertion hole 211. When the first insertion block 221 is fully inserted into the first slot 121, the positioning protrusion 212 is fully embedded in the positioning hole 112, which plays a positioning role and further improves the connection stability between the second connecting part 21 and the first connecting part 11.

[0031] The implementation principle of this application embodiment is as follows: When the manufacturer ships the product, a support member 1 is riveted to the first rod 100, and a connector 2 is riveted to the end of the second rod 200. When it is necessary to quickly assemble the vertical first rod 100 and the horizontal second rod 200, the first insert 221 is aligned with the first slot 121 and inserted downwards. Through the cooperation of the snap-fit ​​block 222 with the through slot 122, the support protrusion 123 with the support slot 224, and the positioning protrusion 212 with the positioning hole 112, the connector 2 and the support member 1 can be quickly connected, thereby quickly installing the second rod 200 onto the first rod 100 without the need for screwdrivers or other tools.

[0032] Example 2 differs from Example 1 in that the support member 1 includes a first connecting part 11 and two support parts 12. The two support parts 12 are arranged circumferentially. This arrangement allows a vertically arranged first rod 100 to be connected to two mutually perpendicular and horizontal second rods 200. Each end of the second rod 200 is fixed with a connector 2, which is inserted into the two support parts 12 respectively. This eliminates the need for a single support member 1, making operation easier and reducing costs.

[0033] The second aspect of this application discloses a diaper changing table. Example

[0034] Reference Figures 4 to 5 A diaper changing table includes a support frame 3, a platform frame 4, and a guardrail 6. The support frame 3 is a rectangular frame body, formed by connecting four vertical rods 31 and several horizontal rods 32. The connection between the vertical rods 31 and the horizontal rods 32 is assembled by the rod connection structure described in Embodiment 2. The four vertical rods 31 are vertically arranged in a rectangular shape, and adjacent vertical rods 31 are connected by two parallel horizontal rods 32. The specific connection method is as follows: the vertical rod 31 serves as the first rod 100, and two support pieces 1 spaced a certain distance apart are fixedly connected to its side wall by rivets, and the opening of the first slot 121 faces upward; the horizontal rod 32 serves as the second rod 200, and both ends of it are fitted with inserts, that is, the ends of the horizontal rod 32 are inserted and riveted to the connection holes 211 of the inserts 2 (refer to...). Figure 4 When installing the support frame 3, simply insert the first plug 221 of the connector 2 at the end of the crossbar 32 into the first slot 121 of the support member 1 on the longitudinal bar 31 from top to bottom. Through the cooperation of the snap-fit ​​block 222 with the through groove 122, the support protrusion 123 with the support groove 224, and the positioning protrusion 212 with the positioning hole 112, the crossbar 32 and the longitudinal bar 31 can be reliably connected quickly without the need for additional tools, thus realizing the quick and detachable connection of the support frame 3.

[0035] Reference Figure 6 The platform frame 4 includes a platform body 42 and bases 43 installed at both ends of the platform body 42. The platform body 42 is composed of several parallel support crossbars 32 spaced at intervals. The bases 43 are elongated and there are two of them. The two bases 43 are arranged opposite to each other. A connecting sleeve 44 is integrally provided on the base 43. The number of connecting sleeves 44 corresponds to the number of support crossbars 32. The two ends of each support crossbar 32 are respectively inserted into the connecting sleeves on the two bases 43. The bottom ends of each base 43 are respectively provided with downward protruding second inserts 41.

[0036] A support base 5 is fixedly connected to the top of the longitudinal rod 31 for mounting the platform frame 4. Specifically, the support base 5 includes a third connecting part 51 and a support part 52 integrally connected to one side thereon. The third connecting part 51 is a sleeve body, which is fitted onto the outside of the longitudinal rod 31 and connected to the longitudinal rod 31 by fasteners. In this embodiment, the sleeve body and the longitudinal rod 31 are fixedly connected by riveting. The support part 52 has a second slot 521 with its opening facing upward. The shape and size of the second insert 41 are adapted to the second slot 521. When installing the platform frame 4, the second insert 41 is aligned with the second slot 521 and inserted, realizing a quick and detachable connection between the platform frame 4 and the support frame 3.

[0037] Furthermore, vertical connecting holes 431 are provided at both ends of the base 43. The top part of the longitudinal rod 31 extends out of the top of the third connecting part 51 and is inserted into the lower half of the connecting hole 211. The guardrail 6 has downward inserting parts 61 at both ends, which are inserted into the upper half of the connecting hole 431. The top of the longitudinal rod 31 abuts against the bottom of the inserting part 61. The guardrail 6 improves the safety of the infant during the nursing process on the nursing table.

[0038] The implementation principle of this application embodiment is as follows: Before leaving the factory, the manufacturer can disassemble each of the longitudinal bars 31 and the transverse bars 32 of the support frame 3. A support member 1 and a support base are fixed on the longitudinal bars 31, and plug-in members 2 are fixed at both ends of the transverse bars 32. The platform frame 4 is disassembled into a long strip-shaped base 43 and each of the supporting transverse bars 32. The guardrail 6 is also disassembled from the base 43. The overall packaging volume is small, which greatly reduces transportation costs. After the consumer purchases the product, they only need to connect the longitudinal bars 31 and the transverse bars 32 to the support member 1 via the plug-in members 2. The quick-connect fittings form the support frame 3. The support crossbar 32 and the connecting sleeve of the base 43 are inserted to form the platform frame 4. When the platform frame 4 is placed on top of the support frame 3, the top of the longitudinal bar 31 is inserted into the connecting through hole 431. The second insert 41 of the base 43 is inserted into the second slot 521 for a tight connection. Finally, the insert part 61 of the guardrail 6 is inserted into the upper half of the connecting through hole 431, so that the bottom end of the guardrail 6 abuts against the top of the longitudinal bar 31, completing the assembly of the entire diaper changing table. Assembly and disassembly are convenient and do not require special tools, reducing the difficulty of use.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
