At this time, the connecting rod on the frame of the children's stroller is enclosed in the clamping hole, and at this time, the locking part on the clamping block hooks the side wall of the fixed seat to prevent the clamping block from opening, thus maintaining the locking. The children's stroller connected with the armrest of the present utility model is safe and reliable. Children can grasp the armrest rod with their hands, and it can also be conveniently disassembled when the armrest is not needed.

[0019] 2. The clamping block of the present utility model is an integrally injection-molded whole. When locking, pull the handle, and the inclined surface on the convex block touches the fixed seat and is squeezed by the fixed seat, and the lower extension piece undergoes elastic deformation. Once the convex block moves to the inside of the fixed seat, the lower extension piece elastically returns. At this time, the convex block can hook the inside of the fixed seat, and the body, upper extension piece and lower extension piece of the clamping block enclose the outside and the upper and lower surfaces of the fixed seat, thus surrounding the seat body of the fixed seat from all around, making the clamping block and the fixed seat lock with each other, ensuring that the armrest of the children's stroller is stably and reliably connected to the frame of the children's stroller.

[0020] 3. The armrest rod of the present utility model can rotate relative to the fixed seat. When the armrest rod is in the vertical position, children can grasp the armrest rod when sitting in the children's stroller, thus ensuring safety. When the armrest rod rotates to the horizontal position, the armrest rod extends the front-back length of the seat of the children's stroller forward, and the armrest rod can support the legs of children, and children can sit in a semi-reclined position. Therefore, it provides users with more function options.

[0032] The present utility model will be further described below in conjunction with the accompanying drawings:

[0033] As Figures 1 to 7 , and Figure 10 shown, a child stroller armrest includes a U-shaped armrest rod 1. Clamping components 2 capable of being clamped and installed on the child stroller frame 100 are provided at both ends of the armrest rod 1. The clamping components 2 include a fixed seat 21 connected to the armrest rod 1. A clamping block 22 that can be opened or closed relative to it is rotatably connected to the fixed seat 21. When the clamping block 22 is closed relative to the fixed seat 21, a clamping hole 23 is formed with the fixed seat 21. A locking portion 24 that can cooperate with the fixed seat 21 to prevent the clamping block 22 from opening when the clamping block 22 is closed relative to the fixed seat 21 is provided on the clamping block 22. The locking portion 24 is a convex block provided on the clamping block 22 and capable of hooking the side wall of the fixed seat 21. When the child stroller armrest is installed on the child stroller frame 100, first rotate the clamping block 22 to open it relative to the fixed seat 21, then the clamping block 22 and the fixed block 21 surround the connecting rod 101 on the child stroller frame 100, and finally rotate the clamping block 22 to close it relative to the fixed seat 21. At this time, the connecting rod 101 on the child stroller frame 100 is surrounded in the clamping hole 23, and at this time, the locking portion 24 on the clamping block 22 hooks the side wall of the fixed seat 21 to prevent the clamping block 22 from opening, so as to maintain the locking. When a child is sitting in the child stroller, he can hold the armrest rod 1 with his hand to ensure safety, and it can also be conveniently disassembled when the armrest is not needed.

[0034] As Figure 6 and Figure 7As shown in the figure, the clamping block 22 includes a body 221. One end of the body 221 is provided with a first hinge portion 222 that is rotatably connected to the fixed seat 21. The other end of the body 221 is provided with an upper extension piece 223 and a lower extension piece 224 that extend to one side thereof. A clamping groove 225 is formed between the upper extension piece 223 and the lower extension piece 224, which can clamp the upper and lower surfaces of the fixed seat 21 when the clamping block 22 closes relative to the fixed seat 21. The convex block is arranged on the lower extension piece 224 and can hook the side wall of the fixed seat 21. A handle 226 that extends downward is provided on the lower extension piece 224. The handle 226, the lower extension piece 224, the upper extension piece 223, the first hinge portion 222 and the body 221 are an integrally injection-molded integral structure. An inclined surface 227 that can be squeezed by the fixed seat 21 is provided on the convex block during the process of the clamping block 22 rotating and closing relative to the fixed seat 21. The clamping block 22 is an integrally injection-molded integral structure, and the molding process is simple, which can reduce the production cost. When locking, pull the handle 226, and the inclined surface 227 on the convex block will touch the fixed seat 21 and be squeezed by the fixed seat 21, and the lower extension piece 224 generates elastic deformation. Once the convex block moves to the inside of the fixed seat 21, the lower extension piece 224 elastically returns. At this time, the convex block can hook the inside of the fixed seat 21, and the body 211, the upper extension piece 223 and the lower extension piece 224 of the clamping block 22 surround the outside and the upper and lower surfaces of the fixed seat 21, so as to surround the fixed seat 21 from all around, making the clamping block 22 and the fixed seat 21 lock with each other, ensuring that the child stroller armrest is stably and reliably connected to the child stroller frame. When disassembly is required, just pull the handle 225 to make the convex block no longer hook the inner side wall of the fixed seat 21, and then rotate the clamping block 22.

[0035] As Figure 6 shown, in order to make the lower extension piece 224 more easily elastically deformed during the process of the clamping block 22 rotating and closing, a through hole 228 is provided in the middle of the lower extension piece 224.

[0036] As Figures 3 to 5 shown, the fixed seat 21 includes a seat body 211. One end of the seat body 211 is provided with a connection shell 212 that is rotatably connected to the armrest rod 1. The other end of the seat body 211 is provided with an arc-shaped bending portion 213. The end of the bending portion 213 is provided with a second hinge portion 214 that is rotatably connected to the first hinge portion 222. When the clamping block 22 closes relative to the fixed seat 21, the body 221, the upper extension piece 223 and the lower extension piece 224 surround the outer side wall of the seat body 211 and the upper and lower surfaces of the seat body 211. The convex block hooks the inner side wall of the seat body 211. A locking structure 3 for locking the relative positions of the armrest rod 1 and the connection shell 212 is further provided between the armrest rod 1 and the connection shell 212. The seat body 211, the connection shell 212, the bending portion 213 and the second hinge portion 214 are an integrally injection-molded integral structure.

[0037] As Figure 8 and Figure 9 shown, a hinge housing 11 is provided at the end of the armrest rod 1. The locking structure 3 includes a plurality of card slots 31 arranged circumferentially on the hinge housing 11 and the connection housing 212. A spline 32 capable of moving horizontally therein and engaging with the card slots 31 on the hinge housing 11 and the connection housing 212 simultaneously is provided in the space enclosed by the hinge housing 11 and the connection housing 212. An exposed button 33 capable of pushing the spline 32 to disengage from the card slot 31 on the hinge housing 11 when pressed is provided on the hinge housing 11. A return spring 34 capable of pushing the spline 32 to move back to its original position is provided between the spline 32 and the connection housing 212. The button 33 includes a pressing portion 331. A plurality of extension columns 332 capable of passing through the through holes 12 on the hinge housing 11 are arranged circumferentially on the pressing portion 331. A hook 333 capable of hooking the edge of the through hole 12 to prevent the button 33 from coming out is provided at the end of the extension column 332.

[0038] As Figures 8 to 11 shown, the positions where the armrest rod 1 stops after rotating relative to the fixed seat 21 include a vertical position where a child can hold it with their hand and a horizontal position where a child's legs can be supported. When the armrest rod 1 stays in the vertical position, the spline 32 engages with the card slots 31 on the hinge housing 11 and the connection housing 212 simultaneously. When the armrest rod 1 stays in the horizontal position, the spline 32 also engages with the card slots 31 on the hinge housing 11 and the connection housing 212 simultaneously. The armrest rod 1 can rotate relative to the fixed seat 21, so that the position of the armrest rod 1 can be adjusted to facilitate a child to hold it in a comfortable position. Moreover, when the armrest rod 1 is in the vertical position, a child can hold the armrest rod when sitting in the baby stroller, thus ensuring safety. When the armrest rod 1 rotates to the horizontal position, the armrest rod 1 extends the front-back length of the baby stroller seat forward. The armrest rod 1 can support a child's legs, and the child can sit in a semi-reclined position. Therefore, the armrest rod 1 can move and be locked in multiple positions, thus providing more choices for users to make the child sit comfortably and safely.
