Description

Technical Field

[0001] The utility model relates to the technical field of infant products, in particular to a seat frame and infant care equipment. Background Art

[0002] In existing baby cribs and other products, detachable structures are often used to connect the various components for easy packaging and transportation. In particular, crib frames and cradles, which are used to support infants, are bulky once assembled. Therefore, these structures are disassembled into multiple rods and connected with multiple connectors to significantly reduce their bulk during packaging and transportation.

[0003] The existing detachable seat frame structure generally includes a bottom connecting plate, four bottom bars, an upper frame that can be further decomposed, two vertical bars, and two bottom corner connectors. The bottom connecting plate, four bottom bars, and two bottom corner connectors are connected to form a bottom frame, and the vertical bars are connected between the bottom corner connectors and the upper frame, thereby forming a three-dimensional seat frame. However, in order to facilitate self-assembly by users, the bottom bars are generally identical, and in each bottom corner connector, the two bottom bars are inserted into the bottom corner connectors relative to each other along the same axis and then tightened by screws. This will cause the bottom corner connectors to slip relative to the bottom bars when a load is applied to the seat frame during use due to the imbalance of the load force (when one side is heavy or there is a horizontal thrust) (when tightened with screws) or swing (when screws are inserted into the bottom bars, gaps will be formed after long-term use), thereby causing the vertical bars to topple over or swing with the upper frame, creating a safety risk. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art described above, the present invention provides a seat frame that does not tilt or shake, has high stability, good safety, and low cost.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A seat frame includes a bottom connecting plate, four bottom bars, an upper frame, two vertical bars, and two bottom corner connectors.

[0007] The upper enclosure frame includes two upper connecting members and a plurality of upper enclosure rods, wherein one upper connecting member, a portion of the upper enclosure rods, another upper connecting member, and the remaining portion of the upper enclosure rods are sequentially connected end to end in a detachable manner in series;

[0008] The four bottom bars are detachably connected to two opposite sides of the bottom connecting plate in groups of two. The two bottom bars in each group are connected to a vertical bar via a bottom angle connector. Each vertical bar is also connected to an upper connector.

[0009] A first plug-in hole and a second plug-in hole are provided on the bottom corner connector. One end of a bottom rod can be detachably plugged into the first plug-in hole, and one end of the other bottom rod can be detachably plugged into the second plug-in hole. The axis of the first plug-in hole and the axis of the second plug-in hole are arranged at an angle.

[0010] In the detachable seat frame of this embodiment, the axis of the first plug-in hole and the axis of the second plug-in hole are arranged at an angle, so that the bottom angle connector cannot rotate relative to the two bottom rods connected to it, so that the seat frame is relatively stable when a load is applied and will not tilt or shake, thereby solving the problem of the upper frame of the prior art being prone to tipping over or swaying when subjected to a load. The seat frame has high stability and good safety, and the overall structure can also be made extremely simple, with low production costs.

[0011] Furthermore, a third plugging hole is provided on the bottom corner connector, and one end of the vertical rod is detachably plugged into the third plugging hole.

[0012] Furthermore, the bottom corner connector includes a transverse main body and an upper extension body. The transverse main body is in a horizontally arranged triangular shape. The first plug-in hole and the second plug-in hole are arranged in the transverse main body. The upper extension body is integrally fixed to the outer corner of the transverse main body, and the third plug-in hole is arranged in the upper extension body.

[0013] Furthermore, one side of the transverse body facing the bottom connecting plate is in an arc shape.

[0014] Furthermore, the upper connecting member is provided with a fourth plugging hole, and the other end of the vertical rod is detachably plugged into the fourth plugging hole.

[0015] Furthermore, the axis of the first plugging hole is parallel to the horizontal plane, the axis of the second plugging hole is parallel to the horizontal plane, and the axis of the third plugging hole is perpendicular to the horizontal plane.

[0016] Furthermore, the bottom connecting plate is provided with four fifth plugging holes corresponding to the four bottom rods.

[0017] Furthermore, the bottom rod includes a transverse section, a bent transition section, and an oblique section connected in sequence. The transverse section, the bent transition section, and the oblique section extend on the same plane, and the extension direction of the transverse section and the extension direction of the oblique section are arranged at an angle. The end of the transverse section can be detachably plugged into the bottom connecting plate, and the end of the oblique section can be detachably plugged into the first plug hole or the second plug hole on the bottom angle connector.

[0018] Furthermore, the two bottom bars in each group have the same shape and are symmetrically arranged, and the distance between the two transverse sections is smaller than the distance between the outermost sides of the two bent transition sections.

[0019] Based on the same concept, the present invention also provides an infant care device, which is equipped with the above-mentioned seat frame. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See Figures 1 to 3The present invention discloses a seat frame 1 and infant care equipment using the seat frame 1. The seat frame 1 includes a bottom connecting plate 11, four bottom bars 12, an upper frame 13, two vertical bars 14, and two bottom corner connectors 15. The four bottom bars 12 are detachably connected to two opposite sides of the bottom connecting plate 11 in groups of two. The two bottom bars 12 in each group are connected to a vertical bar 14 via a bottom corner connector 15. Each vertical bar 14 is also connected to the upper frame 13.

[0029] The bottom connecting plate 11 is used to connect with other components of the infant care device, and specifically can be connected with a drive mechanism or a support structure, for example.

[0030] The upper frame 13 includes two upper connecting members 131 and a plurality of upper surrounding rods 132. An upper connecting member 131, a portion of the upper surrounding rods 132, another upper connecting member 131, and the remaining upper surrounding rods 132 are sequentially connected end to end in a detachable manner in series, thereby forming an upper frame 13 of a desired shape. It is understood that the shapes of the upper surrounding rods 132 can be the same or different. This is only to illustrate that the upper frame 13 can also be disassembled into multiple parts for packaging and transportation. One end of each vertical rod 14 is connected to a bottom corner connector 15, and the other end of each vertical rod 14 is connected to an upper connecting member 131.

[0031] See Figure 2 and Figure 2 With reference to the direction shown, as a specific example, a plurality of upper enclosure rods 132 may specifically include a first upper enclosure rod 132, a second upper enclosure rod 132, a third upper enclosure rod 132, a fourth upper enclosure rod 132, a fifth upper enclosure rod 132, and a sixth upper enclosure rod 132, and the connecting member is T-shaped, one end of the first upper enclosure rod 132 is detachably connected to the rear end of the connecting member on the left, the other end of the first upper enclosure rod 132 is detachably connected to one end of the second upper enclosure rod 132, the other end of the second upper enclosure rod 132 is detachably connected to the rear end of the connecting member on the right, one end of the third upper enclosure rod 132 is detachably connected to the front end of the connecting member on the right, the other end of the third upper enclosure rod 132 is detachably connected to one end of the fourth upper enclosure rod 132, the other end of the fourth upper enclosure rod 132 is detachably connected to one end of the fifth upper enclosure rod 132, the other end of the fifth upper enclosure rod 132 is detachably connected to one end of the sixth upper enclosure rod 132, and the other end of the sixth upper enclosure rod 132 is detachably connected to the front end of the connecting member on the left. Of course, the number of the upper enclosure rods 132 can be changed as needed, and this embodiment does not specifically limit the number of the upper enclosure rods 132.

[0032] Preferably, a first plug-in hole 151 and a second plug-in hole 152 are provided on the bottom corner connector 15, one end of a bottom rod 12 is detachably plugged into the first plug-in hole 151, and one end of the other bottom rod 12 is detachably plugged into the second plug-in hole 152, and the axis of the first plug-in hole 151 and the axis of the second plug-in hole 152 are arranged at an angle.

[0033] In the above scheme, in the detachable seat frame 1 of this embodiment, the axis of the first plug hole 151 and the axis of the second plug hole 152 are arranged at an angle, so that the bottom angle connector 15 cannot rotate relative to the two bottom rods 12 connected to it, so that the seat frame 1 is relatively stable when a load is applied, and will not tilt or shake, with high stability and good safety. In addition, the overall structure can also be made extremely simple, and the production cost is low.

[0034] Preferably, the angle between the axis of the first plug hole 151 and the axis of the second plug hole 152 ranges from 70 degrees to 120 degrees. More preferably, as a specific example, the angle between the axis of the first plug hole 151 and the axis of the second plug hole 152 is 90 degrees.

[0035] See Figure 3 The bottom corner connector 15 is further provided with a third insertion hole 153, into which one end of the vertical rod 14 is detachably inserted, thereby achieving a detachable connection between the bottom corner connector 15 and the vertical rod 14. Specifically, the axis of the first insertion hole 151 is parallel to the horizontal plane, the axis of the second insertion hole 152 is parallel to the horizontal plane, and the axis of the third insertion hole 153 is perpendicular to the horizontal plane.

[0036] Recombination Figure 1 and Figure 2 The upper connecting piece 131 is provided with a fourth plugging hole 1311, and the other end of the vertical rod 14 is detachably plugged into the fourth plugging hole 1311 to realize a detachable connection between the upper connecting piece 131 and the vertical rod 14; the bottom connecting plate 11 is provided with four fifth plugging holes 111 corresponding to the four bottom rods 12 respectively, to realize a detachable connection between the bottom rods 12 and the bottom connecting plate 11.

[0037] It can be understood that the connection between the bottom rod 12 and the bottom angle connector 15, the connection between the bottom rod 12 and the bottom connecting plate 11, the connection between the vertical rod 14 and the bottom angle connector 15, and the connection between the vertical rod 14 and the upper connector 131 can be selectively reinforced and positioned with screws or spring clips to prevent the connections from loosening.

[0038] It is understandable that in some other preferred embodiments, the vertical rod 14 may also be directly fixed to the bottom corner connector 15, or the vertical rod 14 may also be directly fixed to the upper connector 131. Because when the vertical rod 14 and the bottom corner connector 15 or the upper connector 131 are not detachable, their volume will not be very large and will not take up too much packaging and transportation space.

[0039] See Figure 3 In this embodiment, the bottom corner connector 15 preferably includes a transverse main body 154 and an upper extension 155. The transverse main body is horizontally arranged in a triangular shape. The first and second insertion holes 151 and 152 are disposed in the transverse main body 154. The upper extension 155 is integrally fixed to the outer corner of the transverse main body 154. The third insertion hole 153 is disposed in the upper extension 155. The bottom corner connector 15 thus constructed has high overall strength and good connection stability. Depending on the needs of use, a support plate (usually foldable or multiple plates) is generally installed, and the support plate is supported by the multiple bottom bars 12. The transverse main body 154 can also provide a certain amount of support for the support plate (it is understood that whether support is provided depends on the shape and arrangement of the support plate, and may not provide support for the support plate).

[0040] More preferably, one side of the transverse body 154 facing the bottom connecting plate 11 is in an arc shape to avoid forming a sharp corner contact after the supporting plate is placed.

[0041] See Figure 3 In this embodiment, the bottom bar 12 includes a sequentially connected transverse section 121, a bent transition section 122, and an oblique section 123. The transverse section 121, the bent transition section 122, and the oblique section 123 extend on the same plane, and the extension direction of the transverse section 121 and the extension direction of the oblique section 123 are arranged at an angle. The end of the transverse section 121 is removably connected to the bottom connecting plate 11, and the end of the oblique section 123 is removably connected to the first insertion hole 151 or the second insertion hole 152 on the bottom corner connector 15. This structure of the bottom bar 12 helps to strengthen the bottom bar 12 and enhance the supporting effect of the bottom bar 12.

[0042] Specifically, the two bottom bars 12 in each group have the same shape and are symmetrically arranged to facilitate production and save costs, and users do not need to distinguish them when assembling them themselves to reduce the difficulty of assembly. The distance between the two horizontal sections 121 is smaller than the distance between the outermost sides of the two bent transition sections 122, so that an outer support area is formed to support the support plate when in use, and the size of the bottom connecting plate 11 can be made smaller, which is conducive to further reducing costs.

[0043] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
