[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figures 1-19This utility model provides an embodiment of a novel stroller seat, comprising a base 14, a connecting seat 5, and a handle 3. The base 14 includes a seat plate 1402. Outer discs 1401 are fixedly installed at both the front and rear ends of one side of the upper surface of the seat plate 1402, and toothed discs 1403 are installed on opposite sides of the two outer discs 1401. A base plate 1404 is fixedly installed at the midpoint of the lower surface of the seat plate 1402 by multiple bolts. A back plate 2 is rotatably installed between the two outer discs 1401 via a rotating shaft, and guardrails 15 are fixedly engaged at the front and rear ends of the rotating shaft. A head canopy 1 is rotatably installed on the upper part of the front and rear sides of the inner wall of the back plate 2. The head canopy 1 includes two first-fixed seats 102, which are opposite to each other. One side is rotatably connected to a second fixing seat 103 via a pivot and is mounted on the back plate 2 via the pivot. A foldable canopy 101 is installed on the two second fixing seats 103. The two first fixing seats 102 and the second fixing seats 103 are both set in a sawtooth shape on opposite sides. A limiting component 16 for adjusting and limiting the tilt angle of the back plate 2 is embedded in the lower end of the front and rear sides of the inner wall of the back plate 2. An outer plate seat 20 is fixedly installed on the lower end of the chassis 1404. An inner plate seat 21 is rotatably installed inside the outer plate seat 20. A positioning block 22 is embedded in the upper end of the front end of the outer wall of the inner plate seat 21. A positioning groove 1405 matching the positioning block 22 is opened at the midpoint of the front and rear ends of the chassis 1404.

[0041] In use, the canopy 1 can be quickly unfolded by pulling it outwards to achieve a sunshade effect. The back panel 2 is assembled with the toothed disc 1403 by the inner limiting component 16. The angle of the back panel 2 can be quickly adjusted by the position of the limiting component 16 on the toothed disc 1403 at different tooth grooves. At the same time, the chassis 1404 can rotate circumferentially along the inner seat 21. Since the two positioning grooves 1405 on the chassis 1404 are symmetrically designed, the positioning block 22 will automatically rotate when the chassis 1404 is rotated 180 degrees. The positioning block 22 is embedded in the positioning groove 1405 for restriction, thereby reminding the user that it has rotated 180 degrees. The rear end of the positioning block 22 is provided with a positioning spring. When the positioning block 22 is pressed, the positioning spring is caused to contract. At this time, the positioning block 22 retracts inward and disengages from the positioning groove 1405, allowing it to rotate. After rotating 180 degrees, another positioning groove 1405 is located at the front end of the positioning block 22, releasing the squeezing force on the positioning block 22. Thus, under the reset of the positioning spring, the positioning block 22 is pushed into the positioning groove 1405 to complete the restriction.

[0042] Reference Figures 5-7 and Figures 15-17The handle 3 includes a ring handle 301 and a connecting shell 302. Rotating blocks 307 are embedded and engaged at both the front and rear ends of the connecting shell 302. Two symmetrical inner blocks 308 are fixedly arranged between the two rotating blocks 307 inside the connecting shell 302. The two inner blocks 308 are connected by a spring. Each inner block 308 has an inner groove 17 on its upper surface, and an inclined block 18 is fixedly arranged on one side of the inner groove 17. A pressing block 306 is also embedded inside the two inner grooves 17. The pressing block 306 is U-shaped, with both ends of its lower end having inclined cut surfaces corresponding to the inclined block 18. Connecting blocks 3010 are vertically slidably embedded at both the front and rear ends of the lower side of the connecting shell 302. A protruding rod 309 is fixedly arranged at the upper end of the connecting block 3010, and a protruding post 3011 is fixedly arranged at the lower end. A steel rope 304 is fixedly arranged on each of the two protruding posts 3011. A first connecting rod 4 is fixedly installed on the front and rear sides of the lower end of the outer shell 302, and the other end of the first connecting rod 4 is installed with a mounting seat 303 by bolts. The lower ends of the two mounting seats 303 are embedded with protrusions 305, and the upper ends of the protrusions 305 are sleeved with the first steel rope 304. The outer walls of the two rotating blocks 307 are fixedly provided with six protrusions, and the protrusions are in pairs as a group. The end of the ring handle 301 near the two rotating blocks 307 is fixedly provided with an internal gear plate, and the tooth groove of the internal gear plate is fitted with the protrusion. The ends of the two first connecting rods 4 away from the connecting shell 302 are slidably sleeved in the connecting seat 5. The connecting seat 5 includes a seat body 501. The front and rear ends of one side of the seat body 501 are fixedly provided with outer rods 502. The two first connecting rods 4 pass through the interior of the two outer rods 502 and slide into the interior of the two second connecting rods 12. The two second connecting rods 12 are provided with through holes at the midpoint of opposite sides.

[0043] Specifically, when it is necessary to change the angle of the ring handle 301, the pressing block 306 is pressed inward to press down on the two inclined blocks 18. During the pressing of the inclined blocks 18, the two inner blocks 308 are displaced relative to each other. During the movement of the inner blocks 308, the rotating block 307 will also move. At this time, the protrusion on the rotating block 307 moves away from the tooth groove of the inner gear plate of the ring handle 301, and the ring handle 301 is no longer restricted and can be rotated for adjustment. When the ring handle 301 is rotated downward to a folded position, the protrusion 309 will not be affected by the inner gear plate. When the teeth are squeezed, the protruding rod 309 moves upward and is exposed. The connecting block 3010 at the lower end also moves upward and pulls the lower protruding post 3011 and the first steel rope 304 fixedly connected to the protruding post 3011 upward. During the upward movement of the first steel rope 304, it will pull the protrusion 305 located inside the mounting base 303 at the other end to move upward. At this time, the protrusion 305 no longer passes through the lower end of the outer rod 502 and has a limiting effect. Then, by pressing and pushing the connecting shell 302, the first connecting rod 4 is driven to slide into the second connecting rod 12 to complete the storage and use.

[0044] Reference Figure 2 , Figure 18 and Figure 19 A support 19 is fixedly installed on one side of the outer wall of the inner seat 21 and is fixedly connected to the connecting seat 5. A hinge seat 6 is fixedly installed on the lower end face of the connecting seat 5, and a first bracket 7 is rotatably connected to the hinge seat 6. A self-locking rear wheel 8 is installed on the front and rear sides of the lower end of the first bracket 7. A second support rod 25 is rotatably installed on both the front and rear ends of the lower end of the inner seat 21. A sliding seat 24 is rotatably connected to the lower end of the two second support rods 25, and a sleeve 26 is fixedly installed on the front and rear ends of the sliding seat 24. A conical column 27 is embedded in the front and rear ends of the midpoint inside the sleeve 26, and the two conical columns 27 are connected by a telescopic spring. A second support rod 25 is fixedly installed inside the two sleeves 26, and a second bracket 11 is fixedly installed on the other end of the second support rod 25. A front wheel 10 is installed on both the front and rear sides of the lower end of the second bracket 11.

[0045] Specifically, when the first connecting rod 4 slides into the second connecting rod 12, the first connecting rod 4 will squeeze the conical column 27 located at the through hole of the second connecting rod 12 during the sliding process, causing it to retract inward. This releases the purpose of the conical column 27 in restricting the sliding seat 24 after passing through the through hole. At this time, the folding and storage function can be completed by pressing the base 14 and the first bracket 7.

[0046] Reference Figure 1 , Figure 8 and Figure 9 The back panel 2 includes an outer frame 201 and two side boxes 202. The limiting component 16 is embedded inside the side box 202. The limiting component 16 includes a limiting block 1605. A connecting post 1604 is embedded in the upper end of the front face of the limiting block 1605. A second steel rope 1602 is fixedly installed on the upper end of the connecting post 1604. A top block 1601 is fixedly installed at the midpoint of the upper end of the limiting block 1605. A connecting spring 1603 is sleeved on the outside of the top block 1601. A limiting rod 1606 is fixedly installed at the lower end of the limiting block 1605. Multiple toothed grooves are opened on the same toothed disc 1403. The limiting rod 1606 is embedded in one of the toothed grooves.

[0047] Specifically, such as Figure 1As shown, a pull plate is movably embedded in the upper part of one side of the outer frame 201 of the back plate 2. The lower end of the pull plate is connected to two No. 2 steel ropes 1602 respectively. When it is necessary to adjust the angle of the back plate 2, the pull plate is pulled to drive the two No. 2 steel ropes 1602 to move. Then the connecting column 1604 connected to the No. 2 steel ropes 1602 is pulled. The connecting column 1604 is locked in the top block 1601, causing the top block 1601 to be pulled and driving the lower limiting block 1605 and limiting rod 1606 to move upward. This causes the limiting rod 1606 to disengage from the toothed groove in the toothed disc 1403. At this time, the back plate 2 is rotated to adjust the angle and the pull plate is released. Since the connecting spring 1603 sleeved on the outside of the top block 1601 is embedded inside, it is compressed and squeezed when pulled. After the pull plate is released, it is no longer under force, and the connecting spring 1603 automatically returns to its original position to complete the locking and limiting effect.

[0048] Reference Figures 1-2 and Figure 18 The front and rear ends of the first bracket 7, which is close to the hinge seat 6, are rotatably connected to the two first support rods 23 respectively, ensuring smooth rotation and folding function when folding and storing.

[0049] Reference Figure 1 and Figure 2 A foot pedal 13 is fixedly installed on the upper end of the second bracket 11, and a foldable canopy 9 is installed between the first bracket 7 and the second bracket 11.

[0050] Specifically, the bottom canopy structure is convenient for carrying and storing small items such as baby bottles and toys when going out, and it is made of canvas material, which is easy to fold and store; while the foot pedal 13 provides a footrest for infants and young children.

[0051] Working principle: When folding for storage, press the pressing block 306 inward to press down the two inclined blocks 18. During the pressing of the inclined blocks 18, the two inner blocks 308 are displaced relative to each other. As the inner blocks 308 move, they also move the rotating block 307. At this time, the protrusion on the rotating block 307 moves away from the tooth groove of the inner toothed disc of the ring handle 301, and the ring handle 301 is no longer restricted and can be rotated for adjustment. When the ring handle 301 is rotated downward to the folded storage position, the protruding rod 309 will not be squeezed by the teeth of the inner toothed disc. When pressed, the protruding rod 309 moves upward and is exposed. The connecting block 3010 at the lower end also moves upward and pulls the lower protruding post 3011 and the first steel rope 304 fixedly connected to the protruding post 3011 upward. During the upward movement of the first steel rope 304, it will pull the protrusion 305 located inside the mounting base 303 at the other end to move upward. At this time, the protrusion 305 no longer passes through the lower end of the outer rod 502 and has a limiting effect. Then, by pressing and pushing the connecting shell 302, the first connecting rod 4 is driven to slide into the second connecting rod 12 to complete the storage and use.

[0052] Secondly, when the first connecting rod 4 slides into the second connecting rod 12, the first connecting rod 4 will squeeze the conical column 27 located at the position of passing through the through hole of the second connecting rod 12 during the sliding process, causing it to retract inward, thereby releasing the purpose of the conical column 27 restricting the sliding seat 24 after passing through the through hole. At this time, the folding and storage function can be completed by pressing the base 14 and the first bracket 7.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
