[0053] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0054] Embodiment 1:

[0055] like Figure 1 and Figure 2 As shown, a portable child chair 1 includes a seat portion 11 and a support portion 12. The seat portion 11 and the support portion 12 are detachably connected, and both the seat portion 11 and the support portion 12 are detachable structures. When the child chair 1 needs to be carried and transported, the seat portion 11 and the support portion 12 can be disassembled together, thereby obtaining a foldable seat body 111 and a plurality of carrying units.

[0056] It should be known that the seat body 111 is generally made of a flexible material, such as canvas; so that when carrying and transporting, the seat body 111 can be folded flat or folded into multiple layers according to the transportation space to facilitate carrying. At the same time, the other structures of the seating portion 11 are generally a bracket assembly 13 that supports the seat body 111, and the bracket assembly 13 and the support portion 12 are generally composed of rods and blocks. Therefore, the bracket assembly 13 and the support portion 12 can be designed to be detachable, and then when transportation is required, the bracket assembly 13 and the support portion 12 can be split into multiple rods and blocks, and multiple carrying units can be formed by the rods and blocks. And when transporting, the carrying units can be dispersed to multiple places for transportation according to the actual transportation space, or the carrying units can be bundled together for transportation; a variety of transportation methods can effectively improve the portability of the child chair 1.

[0057] In this embodiment, Figures 2 to 5 As shown, the carrying unit includes a plurality of first rods 1311 and a plurality of second rods 1312; the first rods 1311 and the second rods 1312 are detachably connected to form a support rod 131 for supporting the four corners of the outer side of the seat body 111. That is, when the child chair 1 is used, the plurality of first rods 1311 and the plurality of second rods 1312 can be assembled to form a plurality of support rods 131 to support the seat body 111. When the child chair 1 needs to be carried and transported, the plurality of support rods 131 can be split into a plurality of first rods 1311 and a plurality of second rods 1312 as a part of the carrying unit for carrying and transportation.

[0058] In this embodiment, in order to improve the assembly convenience of the support rod 131 and ensure the connection quality, there are various specific assembly structures of the first rod body 1311 and the second rod body 1312, including but not limited to the following two.

[0059] Assembly structure 1: Figure 3 and Figure 7 As shown, the cross-sections of the first rod body 1311 and the second rod body 1312 are adaptive non-circular, and the first rod body 1311 and the second rod body 1312 are sleeved together to form the support rod 131 .

[0060] Assembly structure 2: Figure 3 As shown, the first rod body 1311 and the second rod body 1312 are sleeved together and fastened by a fastener 136 to form a support rod 131 .

[0061] It can be understood that both assembly structure 1 and assembly structure 2 can meet the use requirements of this embodiment. For assembly structure 1, the non-circular cross-section of the first rod body 1311 and the second rod body 1312 can ensure that the first rod body 1311 and the second rod body 1312 can only be plugged in and out in the extension direction, and cannot be rotated relative to each other, thereby ensuring the structural stability of the support rod 131 when in use. For assembly structure 2, there is no requirement for the cross-sectional shape of the first rod body 1311 and the second rod body 1312, but the use effect of the non-circular cross-section is better; and the fastener 136 can not only limit the relative rotation of the first rod body 1311 and the second rod body 1312, but also limit the plugging and unplugging of the first rod body 1311 and the second rod body 1312 after the assembly is completed. Compared with assembly structure 1, the structural stability of the support rod 131 can be further improved.

[0062] In this embodiment, Figure 2 , Figure 8 , Fig.10 and Fig.11 As shown, support sleeves 1110 are provided at the four outer corners of the seat body 111 , and the support rod 131 can be upwardly plugged into the support sleeves 1110 through the upper end of the second rod body 1312 , thereby supporting the seat body 111 .

[0063] It is understandable that in order to ensure that the seat body 111 is tensioned to support the child's sitting, at least its four corners need to be supported. At the same time, in order to facilitate the rapid assembly and disassembly of the seat body 111 and the support rod 131, support sleeves 1110 can be set at the four corners of the outer side of the seat body 111; then the number of corresponding support rods 131 is also four. The four support rods 131 can be divided into a first group and a second group arranged front and back. The two support rods 131 of the first group can be detachably plugged with the support sleeves 1110 on both sides of the front part of the seat body 111, thereby supporting the legs of the child when sitting. The two support rods 131 of the second group can be detachably plugged with the support sleeves 1110 on both sides of the rear part of the seat body 111, thereby supporting the back of the child when sitting. That is, through the detachable plugging of the two groups of support rods 131 and the support sleeves 1110 at the four corners of the seat body 111, the child sitting on the seat body 111 can be supported as a whole.

[0064] In this embodiment, Figure 2 , Figure 3 and Fig.11 As shown, when the second rod 1312 supports the seat body 111 , the angle between the second rod 1312 and the vertical direction is 0-30°.

[0065] It should be noted that, since the seat body 111 is made of a flexible material, the seat body 111 will sag downward under the action of gravity when a child is sitting on it. If the support rod 131 is a straight rod as a whole, the support rod 131 needs to be connected to the subsequent support member 134 and the seat body 111 at a larger tilt angle. Therefore, when the seat body 111 is sag, the seat body 111 may interfere with the support rod 131.

[0066] In this embodiment, the support rod 131 is divided into two sections, and the second rod 1312 is tilted with the first rod 1311, so that the support rod 131 can be connected to the support member 134 while ensuring that the second rod 1312 is in a vertical or vertical state, thereby reducing or avoiding the possibility that the seat body 111 contacts the support rod 131 when it is recessed. In terms of parameters, the angle between the second rod 1312 and the vertical direction is α, and the value of the angle α is 0°-30°; when the angle α=0°, it means that the second rod 1312 is in a vertical state.

[0067] In this embodiment, Figures 2 to 6As shown, the carrying unit further includes a support rod 135. When assembling the bracket assembly 13, the support rod 135 is detachably installed on the support rod 131 and is supported and cooperated with the middle part of the front end of the seat body 111 through the arched structure in the middle, so that two placement areas for placing the legs at intervals are formed on both sides of the front end of the seat body 111. When carrying and transporting, the support rod 135 can be directly disassembled from the support rod 131 to be used as one of the carrying units.

[0068] It should be known that the seat body 111 is made of flexible material, and the support points of the support rod 131 on the seat body 111 are located at the four corners of the seat body 111. That is, the front middle area of the seat body 111 is not supported by the bracket assembly 13, resulting in poor tensioning ability in the front middle area of the seat body 111. When a child sits on the seat body 111, under the action of the gravity of the child's legs, the front middle area of the seat body 111 will sink downward, causing the two sides of the front of the seat body 111 to tilt, and then it will lead to the child's legs often fitting and approaching each other, that is, the two sides of the front of the seat body 111 will produce a binding feeling of approaching the middle on the child's legs.

[0069] In this embodiment, by providing an upward arched structure in the middle of the front part of the riding part 11 of the support rod 135 to support the middle of the front part of the seat body 111, a placement area for placing the child's legs and concave downward is formed on each side of the front part of the seat body 111; thus, the comfort of the child's riding can be effectively improved.

[0070] It should be known that the arched structure in the middle of the support rod 135 can be obtained by welding or fastening connection of a rod in the shape of "U", "凵" or trapezoid and a straight rod. It can also be as Figure 4 shown, the support rod 135 is obtained by bending in the middle area.

[0071] In this embodiment, as Figure 3 and Figure 7 shown, jacks are provided on the support rods 131 on both sides of the front part of the seat body 111, and the support rod 135 can be installed by inserting both ends into the jacks.

[0072] It can be understood that the support rod 135 has a certain deformation reset ability. Therefore, when installing the support rod 135, one end of the support rod 135 can be inserted into the jack on one side of the support rod 131 first, and then the support rod 135 is bent to a certain extent until the other end is aligned with the jack on the other side of the support rod 131, and then the support rod 135 can be released. Then, the support rod 135 can insert the other end into the corresponding jack through deformation reset. When disassembling the support rod 135, just reverse the above process.

[0073] In this embodiment, Figure 3 and Figure 7 As shown, the end of the support rod 135 is provided with a locking groove 1350. When the support rod 135 is installed, the locking groove 1350 can extend into the insertion hole along with the end of the support rod 135, and then the outside of the support rod 131 extends into the insertion hole through the fastener 136 to limit the locking groove 1350, so as to ensure the stability of the installation structure of the support rod 135.

[0074] It should be known that if the support rod 135 is directly plugged into the socket, the support rod 135 may sway in the circumferential direction during use, thereby affecting the user experience of the support rod 135. Of course, the support rod 135 can also be plugged into the socket with a non-circular cross-section, but when the support rod 135 is subjected to a large force, it may still be detached from the socket through deformation. Therefore, when installing the support rod 135, it is necessary to limit the support rod 135; the common limiting method is the fastening and locking of the fastener 136. If the fastener 136 and the support rod 135 are only locked and limited by abutting each other, although a certain limiting effect can be achieved, there is still a risk that the support rod 135 will be detached from the socket. Therefore, this embodiment provides a locking groove 1350 at the end of the support rod 135 to perform mandatory limiting with the fastener 136 to ensure the safety of the support rod 135.

[0075] Specifically, there are many specific structures of the locking groove 1350, including but not limited to the following three.

[0076] Structure 1: The locking groove 1350 is a thread groove that is threadedly matched with the fastener 136. Therefore, when the support rod 135 is limited, the fastener 136 can be inserted into the jack along the side of the jack and then threadedly engaged with the locking groove 1350, thereby limiting the movement of the support rod 135 along the axial direction of the jack.

[0077] Structure 2: The locking groove 1350 is a groove. Therefore, when the support rod 135 is limited, the fastener 136 can be screwed along the side of the jack, and then the end of the fastener 136 extending into the jack can be aligned with the locking groove 1350 until the end surface of the fastener 136 abuts against the bottom surface of the locking groove 1350. The abutment between the side of the locking groove 1350 and the fastener 136 can limit the movement of the support rod 135 along the axial direction of the jack.

[0078] Structure 3: Figure 6 and Figure 7As shown, the locking groove 1350 is an annular groove. Therefore, when the support rod 135 is limited, the fastener 136 can be screwed along the side of the jack, and then the end of the fastener 136 extending into the jack can approach the locking groove 1350 until the end surface of the fastener 136 abuts against the bottom surface of the locking groove 1350. The abutment between the side of the locking groove 1350 and the fastener 136 can limit the movement of the support rod 135 along the axial direction of the jack.

[0079] It is understandable that the above three structures can meet the use requirements of this embodiment. However, considering the processing accuracy of the support rod 135, if the size of the locking groove 1350 is adapted to the diameter of the fastener 136, it is difficult to ensure that the locking grooves 1350 at both ends of the support rod 135 can be aligned with the installation positions of the fasteners 136 corresponding to both ends when the support rod 135 is installed. Therefore, in order to reduce the installation difficulty and processing accuracy of the support rod 135, the extension length of the locking groove 1350 can be lengthened to be greater than the diameter of the fastener 136. Among the above three structures, except for structure one, the length of the locking groove 1350 can be lengthened, that is, the structure of the locking groove 1350 in this embodiment can preferably adopt the above structure two or structure three. A certain fault tolerance space can be generated between the lengthened locking groove 1350 and the installation position of the fastener 136 along the axial direction of the jack to improve the installation convenience of the support rod 135. The specific structure and working principle of the fastener 136 are well-known to those skilled in the art, and common fasteners 136 include screws and bolts. It should be known that for structures 2 and 3, in order to prevent the threads of the fastener 136 from being worn by the locking groove 1350, a polished rod section can be provided at the front end of the fastener 136 to be plugged into the locking groove 1350.

[0080] In this embodiment, there are multiple ways to detachably connect the front middle part of the seat portion 11 and the arched structure of the support rod 135, which can be a fixed connection or a non-fixed connection. In order to facilitate the assembly and disassembly of the seat body 111 and the support rod 135, the support rod 135 and the seat body 111 are preferably connected in a non-fixed detachable manner. Specifically, the seat portion 11 is detachably connected to the arched structure of the support rod 135 through a provided clamping portion on the outer side of the front middle part.

[0081] Specifically, there are multiple ways of detachably connecting the clamping portion and the arched structure in the middle of the support rod 135, including but not limited to the following two.

[0082] Connection method 1: Figure 2 and Figure 8As shown, a notch 1111 with a downward opening is provided in the middle of the front end of the seat body 111. Thus, when assembling the support rod 135 and the seat body 111, the support rod 135 can be snapped or buckled with the seat body 111 by being snapped upward into the notch 1111 through the arched structure in the middle.

[0083] Connection method two: A socket with a downward opening is provided in the middle of the front end of the seat body 111. Thus, when assembling the support rod 135 and the seat body 111, the support rod 135 can extend upward into the socket through the arched structure in the middle to achieve socket connection with the seat body 111.

[0084] It can be understood that for connection method one, a rigid support block can be fixedly provided on the outer side of the middle area of the front part of the seat body 111, and the notch 1111 is provided on the support block. Similarly, for connection method two, a piece of fabric can be sewn on the outer side of the middle area of the front part of the seat body 111. An opening-downward socket can be formed between the fabric and the outer side of the seat body 111.

[0085] It can also be understood that for connection method one, the notch 1111 can be an elastic structure, that is, the opening size of the notch 1111 can change elastically. If the size of the notch 1111 is adapted to the size of the support rod 135, the notch 1111 and the support rod 135 are snap-connected. If the opening size of the notch 1111 is smaller than the diameter of the support rod 135 and the internal size of the notch 1111 is adapted to the support rod 135, the notch 1111 and the support rod 135 can be buckled.

[0086] In this embodiment, as Figures 3 to 5 and Fig.11 shown, the carrying unit further includes an armrest 132. When assembling the armrest 132, the armrest 132 is detachably installed on the support rod 131 and is located at the rear of the seat body 111, and then the seating part 11 is held by the armrest 132. When carrying and transporting the children's chair 1, the armrest 132 can be detached from the support rod 131 to be used as one of the carrying units.

[0087] It should be known that the armrest 132 is integrally in a "U" shape, and it can be detachably and fixedly connected to two support rods 131 of the second group respectively at both ends. Thus, when the children's chair 1 is used for traveling, the position of the children's chair 1 can be conveniently adjusted and the use safety of the children's chair 1 can be ensured by holding the armrest 132.

[0088] In this embodiment, as Figure 2 and Fig.11 shown, the seating part 11 further includes a safety belt 112, and the safety belt 112 is detachably installed on the seat body 111 and is detachably and limit-connected to the support rod 131.

[0089] In this embodiment, Figure 2 , Fig.10 and Fig.11 As shown, the safety belt 112 generally adopts a five-point structure; that is, the safety belt 112 includes a pair of first straps 1121, a pair of second straps 1122 and a third strap 1123. The first strap 1121 can protect and restrain the child's shoulders, the second strap 1122 can protect and restrain the child's waist, and the second strap 1122 and the third strap 1123 can cooperate to protect and restrain the child's legs. Among them, the first strap 1121 and the third strap 1123 are directly connected to the seat body 111, and the second strap 1122 can pass through the seat body 111 and cooperate with the bracket assembly 13 to further improve the support stability of the seat body 111 while improving the protection effect of the safety belt 112.

[0090] It is understandable that the support points of the bracket assembly 13 for the seat body 111 are located at the front and rear sides of the seat body 111, and the middle area of ​​the seat body 111 has no support points, that is, the middle area of ​​the seat body 111 is a suspended area. If the safety belt 112 is fully connected to the seat body 111, when the child moves on the seat body 111, the safety belt 112 will drive the seat body 111 to move with the child, and there may be a risk of overturning. In this embodiment, the second strap 1122 of the safety belt 112 passes through the seat body 111 and connects to the bracket assembly 13. After the child sits on the seat body 111 and wears the safety belt 112, the child's range of movement, that is, the range of movement of the seat body 111, will be limited by the connection between the second strap 1122 and the bracket assembly 13; thereby, while ensuring the safety of the child, the stability of the seat body 111 can also be improved.

[0091] Specifically, there are many specific connection structures between the second strap 1122 and the bracket assembly 13, one of which is as follows: Figure 3 and Fig.11 As shown, the middle of the second group of support rods 131 is fixedly provided with a connecting plate 133, and the connecting plate 133 can be fixed to the support rod 131 by screws or welding. The second strap 1122 can pass through the rear of the seat body 111 and be detachably connected to the connecting plate 133, so as to provide a limiting force on the forward tilt of the seat body 111 through the rear structure of the bracket 13.

[0092] In this embodiment, Figure 4 , Figure 5 , Fig. 9 and Fig.11As shown, the carrying unit further includes a pillow portion 1131 and an insertion rod 1132. When the seating portion 11 is assembled, the pillow portion 1131 and the insertion rod 1132 are detachably connected to form a headrest assembly 113 for head support; the headrest assembly 113 can be detachably mounted on the rear side of the seat body 111 through the insertion rod 1132. When the seat body 111 is carried for transportation, the headrest assembly 113 can be detached from the seat body 111, and the headrest assembly 113 can be detached into the pillow portion 1131 and the insertion rod 1132 as two carrying units.

[0093] In this embodiment, there are multiple ways to detachably mount the headrest assembly 113 and the seat body 111 via the insertion rod 1132 , including but not limited to the following three ways.

[0094] Installation method 1: There is only one insertion rod 1132, and the insertion rod 1132 can be connected to two protruding engaging parts 1133 symmetrically arranged at the lower end, and the protruding directions of the two protruding parts 1133 are opposite. Therefore, when the insertion rod 1132 and the seat body 111 are assembled, the insertion rod 1132 can be connected to the notch groove 1114 arranged at the back of the seat body 111 through the two protruding parts 1133.

[0095] Installation method 2: Figures 9 to 11 As shown, the number of the insertion rods 1132 is a pair, and the lower ends of the two insertion rods 1132 are provided with a protruding engaging portion 1133. Therefore, when the insertion rods 1132 and the seat body 111 are assembled, the insertion rods 1132 can be engaged with the spaced notch grooves 1114 on the seat body 111 through the two protruding portions 1133, and the two spaced insertion rods 1132 can limit the rotation of the headrest assembly 113.

[0096] It is understandable that both the above-mentioned setting method 1 and setting method 2 can meet the requirements of this embodiment, but in order to improve the supporting stability of the headrest assembly 113, this embodiment preferably adopts the above-mentioned setting method 2 for the engagement method between the insertion rod 1132 and the seat body 111.

[0097] In this embodiment, Fig.10 and Fig.12 As shown, a plurality of notches 1114 are arranged at intervals along the height direction of the adjustment sleeve 1113; the insertion rod 1132 can be engaged with the notches 1114 at different positions through the engaging portion 1133 to adjust the height of the pillow portion 1131, thereby being able to support the heads of children of different shapes.

[0098] It should be understood that the specific number of the notch grooves 1114 can be selected according to the actual needs of those skilled in the art, for example Fig.10 and Fig.12 As shown, the number of the notch grooves 1114 is four.

[0099] In this embodiment, there are multiple specific engagement methods between the engagement portion 1133 and the notch groove 1114 , including but not limited to the following two.

[0100] Snap-on method 1: the snap-on portion 1133 is elastically retracted and installed along the axis perpendicular to the insertion rod 1132. Then the cross-sectional dimensions of the adjustment sleeve 1113 match the cross-sectional dimensions of the insertion rod 1132. Furthermore, when the insertion rod 1132 and the adjustment sleeve 1113 are plugged in, the snap-on portion 1133 is squeezed by the adjustment sleeve 1113 and can be elastically contracted in the direction close to the insertion rod 1132. When the snap-on portion 1133 moves with the insertion rod 1132 to a position corresponding to the notch groove 1114, the snap-on portion 1133 can be elastically reset to extend out of the insertion rod 1132 until it is snapped in with the corresponding notch groove 1114.

[0101] Snap-in method 2: Figures 9 to 12 As shown, the insertion rod 1132 is a deflection rod, and the protruding directions of the engaging parts 1133 of the two insertion rods 1132 are opposite. The cross-sectional size of the adjustment sleeve 1113 is adapted to the size of the engaging part 1133. When the insertion rod 1132 and the adjustment sleeve 1113 are plugged in, the engaging part 1133 and the adjustment sleeve 1113 are squeezed, so that the insertion rod 1132 can be elastically bent and deformed in the direction opposite to the protruding direction of the engaging part 1133, so that the engaging part 1133 can extend into the adjustment sleeve 1113. When the engaging part 1133 moves with the insertion rod 1132 to correspond to the notch groove 1114, the insertion rod 1132 can drive the engaging part 1133 to move in the protruding direction by deformation reset until the engaging part 1133 is engaged with the corresponding notch groove 1114.

[0102] It can be understood that both of the above-mentioned two snap-fitting methods can meet the requirements of this embodiment. Compared with snap-fitting method 1, the structure of snap-fitting method 2 is simpler. Therefore, this embodiment preferably adopts the above-mentioned snap-fitting method 2 for the specific snap-fitting method between the snap-fitting portion 1133 and the notch groove 1114. After the insertion of the plug rod 1132, the plug rod 1132 and the adjustment sleeve 1113 can be in a natural state or in an elastic state, that is, the distance between the two adjustment sleeves 1113 is less than or equal to the distance between the two plug rods 1132. Therefore, when installing and removing the plug rod 1132, the two plug rods 1132 can be squeezed against each other to reduce the distance to facilitate installation and removal.

[0103] In this embodiment, there are mainly two ways to form the insertion rods 1132. The first way: the two insertion rods 1132 are independent of each other, and the two insertion rods 1132 are detachably fixedly connected to the headrest part 1131 through their upper ends. The second way: a long rod is bent into a "U" shape or a "凵" shape to obtain two parallel insertion rods 1132; then the headrest part 1131 can be detachably installed in the bent area of the long rod through sleeving or other means, and the formed insertion rods 1132 are inserted and installed on the seat body 111.

[0104] In this embodiment, as Fig.10 and Fig.11 shown, the adjusting sleeve 1113 is arranged in the middle or lower part of the rear side of the seat body 111. At the same time, a pair of guiding buckles 1112 are arranged on the upper part of the rear side of the seat body 111, and the insertion rods 1132 can pass through the corresponding guiding buckles 1112 and be inserted into the corresponding adjusting sleeves 1113. Thereby, the supporting length of the insertion rods 1132 and the seat body 111 can be effectively increased, so as to further improve the use stability of the headrest assembly 113.

[0105] In this embodiment, as Figure 1 , Figure 3 , Figure 4 and Fig.13 shown, the carrying unit further includes a support member 134. The second rod body 1312 is inclined with respect to the first rod body 1311, so that each support rod 131 is detachably connected to the support member 134 through the second rod body 1312, and further the seating part 11 is detachably connected to the support part 12 through the support member 134.

[0106] It can be understood that, as can be seen from the foregoing content, the second rod body 1312 is in a vertical or nearly vertical state to support the seat body 111, and the first rod body 1311 is inclined with respect to the second rod body 1312, so that the four support rods 131 can be detachably connected to the support member 134 at the same time. Specifically, the first rod body 1311 can be inserted into the support member 134 with its lower end inclined downward, so that when a child is sitting on the seating part 11, the connection structure between the support rod 131 and the support member 134 is always in a stable state under the action of gravity; and when the seating part 11 is carried and transported, the first rod body 1311 can be directly pulled out of the support member 134 for disassembly and separation.

[0107] In this embodiment, as Figure 4 and Figure 5As shown, from the above content, the bracket assembly 13 can be disassembled to obtain four first rod bodies 1311, four second rod bodies 1312, one armrest 132, one support member 134, and one support rod 135 as carrying units. The above-mentioned multiple carrying units can be carried and transported by bundling and gathering, or can be carried and transported separately.

[0108] In this embodiment, as Figures 13 to 15 shown, the carrying unit further includes at least three legs 122 and a first support base 121. When assembling the support portion 12, the multiple legs 122 can be detachably connected to the first support base 121 to form the required support portion 12; and the support portion 12 can be detachably inserted into the support member 134 through the first support base 121 to support the seating portion 11.

[0109] It can be understood that, for the stability of the support structure, the number of legs 122 included in the support portion 12 is at least three, and the specific number can be selected according to actual needs. For example Fig.13 and Fig.15 shown, the number of legs 122 is four.

[0110] In this embodiment, as Figures 13 to 15 shown, a plurality of slots 1301 with openings facing downwards are arranged along the circumferential direction at the bottom of the support member 134; the number of the first support bases 121 is multiple and in a plate shape. When assembling the support portion 12 and the seating portion 11, the support portion 12 can be vertically inserted into the corresponding slots 1301 through the first support base 121.

[0111] It can be understood that the specific number of the first support bases 121 can be selected according to actual needs. For example Fig.13 and Fig.15 shown, the number of the first support bases 121 is a pair, and two legs 122 are symmetrically and obliquely inserted into each first support base 121; then as Fig.14 shown, the number of the slots 1301 is two corresponding ones, and the two slots 1301 are symmetrically arranged. Since the openings of the slots 1301 face downwards, after the first support base 121 is inserted into the slots 1301, when the support member 134 bears weight, the insertion structure of the first support base 121 and the slots 1301 can be more stable.

[0112] Specifically, as Fig.14 shown, the support member 134 includes a second support base 1341 and a connecting base 1342; the connecting base 1342 is fixedly connected to the second support base 1341. The connecting base 1342 is in a "U" shape, so that the slots 1301 can be symmetrically arranged on both sides of the connecting base 1342.

[0113] In this embodiment, Fig.15 As shown, the legs 122 can be tilted and inserted into the first support seat 121 with the upper end tilted upward, so that when the support portion 12 supports the seat portion 11, the gravity of the seat portion 11 can ensure that the connection structure between the legs 122 and the first support seat 121 is more stable. At the same time, when the support portion 12 is disassembled, four legs 122 and a first support seat 121 can be obtained as a carrying unit. The carrying unit formed after the support portion 12 is disassembled can be bundled and transported together with the carrying unit obtained after the bracket assembly 13 is disassembled.

[0114] Embodiment 2:

[0115] Compared with the first embodiment, the difference of this embodiment is that: Figures 16 to 18 As shown, a through hole 1302 is provided at the center of the support member 134; there is one first support seat 121, and a vertical plug post 1210 is provided at the top of the first support seat 121. When the support portion 12 and the seat portion 11 are assembled, the first support seat 121 can be vertically plugged into the through hole 1302 through the plug post 1210, and the gravity of the seat portion 11 is always downward, which drives the plugging of the through hole 1302 of the support member 134 and the plug post 1210 to remain stable. When carrying and transporting, the plug post 1210 can be pulled out and separated from the through hole 1302.

[0116] It should be known that the specific number of the legs 122 can be selected according to the implementation requirements, but in order to ensure the support stability, the number of the legs 122 is at least three. Fig.16 As shown, there are four legs 122 , and the four legs 122 can be plugged into the first support seat 121 in a circumferential direction around the first support seat 121 , or two legs 122 can form a group, and two groups of legs 122 are symmetrically plugged into the first support seat 121 .

[0117] In this embodiment, Fig.16 and Fig.17 As shown, the support member 134 includes a second support seat 1341 and a support sleeve 1343; the support sleeve 1343 is fixedly connected to the second support seat 1341, and the through hole 1302 is arranged at the center of the support sleeve 1343. When the support portion 12 and the seating portion 11 are assembled, the support portion 12 can be inserted into the through hole 1302 of the support sleeve 1343 through the plug post 1210 arranged on the upper end surface of the first support seat 121 to achieve a detachable connection.

[0118] Specifically, there are many ways to fix the support sleeve 1343 and the second support seat 1341, one of which is as follows: Fig.17As shown, a through hole is provided at the center of the second support seat 1341, and a threaded section is provided at the top of the support sleeve 1343. The support sleeve 1343 can penetrate the through hole upward from the lower end of the second support seat 1341, and then the threaded section of the support sleeve 1343 extends out of the upper end of the second support seat 1341 and is screwed and tightened by the nut 1347.

[0119] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
