Specific embodiments
[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] As Figure 1-7As shown in the figure, a folding inner core structure of a baby stroller includes a first bracket 1 and a second bracket 2 rotatably connected to the top end of the first bracket 1. It is characterized in that: a rotating shaft 3 is arranged in the middle of the first bracket 1, a sleeve 4 is rotatably connected to the outside of the rotating shaft 3, a backrest frame 5 is fixedly connected to the sleeve 4, a sliding tube 6 is slidably connected to the backrest frame 5, a side frame 7 is rotatably connected to one side of the sliding tube 6, and the side frame 7 is rotatably connected to the top end of the first bracket 1; a limiting block 8 is fixedly connected inside the backrest frame 5, a first sliding groove 9 is opened in the middle of the limiting block 8 along the direction of the backrest frame 5, a sliding block 10 is slidably connected in the first sliding groove 9, a first spring 11 is fixed between the sliding block 10 and the limiting block 8, an inclined second sliding groove 12 is opened at the front end of the sliding block 10, a sliding column 13 is slidably connected in the second sliding groove 12, a third sliding groove 14 is opened in the sliding block 10 along the direction of the backrest frame 5, a sliding plate 15 is slidably connected in the third sliding groove 14, a fourth sliding groove 16 which is slidably matched with the sliding plate 15 is opened outside the limiting block 8, and a clamping groove 17 which is matched with the sliding plate 15 is opened on the sliding tube 6; a fixing column 18 is fixedly connected to the bottom end inside the backrest frame 5, an inserting block 19 is slidably connected to the outside of the fixing column 18, a second spring 20 is fixedly connected between the fixing column 18 and the inserting block 19, a slot 21 corresponding to the inserting block 19 is opened on the outside of the rotating shaft 3, the lower end of the inserting block 19 penetrates through the sleeve 4, and the inserting block 19 is slidably connected with the sleeve 4; a driven rope 22 is arranged between the sliding block 10 and the inserting block 19, and a driving rope 23 is arranged at the upper end of the sliding block 10; "L"-shaped rope clamping grooves 24 are opened on both the sliding block 10 and the inserting block 19, and connecting blocks 25 are arranged at both ends of the driving rope 23 and the driven rope 22; moving wheels 26 are arranged at the lower ends of both the first bracket 1 and the second bracket 2; a seat frame 27 is rotatably connected to one side of the sleeve 4, a leg plate 28 is rotatably connected to the other end of the seat frame 27, and the middle of the seat frame 27 is rotatably connected to the middle of the second bracket 2; a chamfer 29 corresponding to the sliding tube 6 is opened on the sliding plate 15; a notch 30 corresponding to the sliding plate 15 is opened on the sliding tube 6; and a through hole 31 which is matched with the sliding plate 15 is opened on the backrest frame 5.
[0025] The specific structure of the rope clamping groove 24 is as Figure 6 shown;
[0026] When folding the baby stroller, by pulling the driving rope 23, the driving rope 23 drives the sliding block 10 connected thereto to move upward. The sliding block 10 slides inside the limiting block 8. When the sliding block 10 slides upward, according to the inclined setting of the second sliding groove 12, the sliding column 13 and the sliding plate 15 slide obliquely. According to the sliding limit of the fourth sliding groove 16 on the sliding plate 15, the sliding plate 15 and the sliding column 13 will move into the backrest frame 5. When the sliding plate 15 moves into the backrest frame 5, it no longer limits the clamping groove 17 on the sliding tube 6; this structure controls the sliding of the sliding plate 15 along the direction of the clamping groove 17 more stably and prevents shaking;
[0027] Meanwhile, while the driving rope 23 drives the slider 10 to move upward, the slider 10 also drives the inserting block 19 to move upward through the driven rope 22. The inserting block 19 slides outside the fixed column 18 and no longer passes through the sleeve 4 to limit the slot 21 on the rotating shaft 3. At this time, the sleeve 4 and the back frame 5 can rotate. When the back frame 5 rotates, the sliding tube 6 thereon slides and the side frame 7 rotates. The sleeve 4 drives the seat frame 27 rotatably connected thereto to rotate, and the seat frame 27 drives the second bracket 2 rotatably connected thereto to rotate. At this time, as Figure 7 shown, the frame of the stroller is folded and stored; through the two-point fixation at the sliding tube 6 and the inserting block 19, the stroller cannot be folded without pulling the driving rope 23, making it more stable to use and preventing accidental folding from hurting the children in the stroller;
[0028] The back frame 5 is provided with a through hole 31 for mating with the sliding plate 15; the outside of the slider 10 is slidably connected to the inside of the back frame 5, and the sliding of the slider 10 is more stable, preventing shaking;
[0029] When it is necessary to unfold and use, rotate the back frame 5 to reset. When the back frame 5 resets, according to the elasticity of the second spring 20, the second spring 20 drives the inserting block 19 to be re-locked into the slot 21. At the same time, the sliding tube 6 also drives the side frame 7 to slide on the back frame 5. According to the elasticity of the first spring 11, when the first spring 11 drives the slider 10 to reset, the slider 10 drives the sliding plate 15 to reset and protrude outside the back frame 5. When the sliding tube 6 slides to the sliding plate 15, according to the setting of the notch 30, the sliding plate 15 moves into the back frame 5 inward, and then according to the elastic force of the first spring 11, the sliding plate 15 pops out and is locked into the slot 17 on the sliding tube 6. At this time, the entire stroller frame is unfolded and can be used;
[0030] The setting of the rope clamping groove 24 and the connecting block 25 facilitates fixing the driving rope 23 and the driven rope 22 to the slider 10 and the inserting block 19.
