【Detailed ways】

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Fig. 1 to Fig. 4 and Fig. 12, a reversible seat for a stroller includes a base 1 that can be connected to a frame 10, the base 1 is connected with a seat body 2, and the The seat body 2 includes a seat plate 21, the seat plate 21 is provided with a protruding convex ring 22, the inner side of the convex ring 22 is provided with a plurality of clamping blocks 31 that extend to the outside of the convex ring 22 and can be telescopically moved, The base 1 is provided with a base cavity 4 that can allow the convex ring 22 to rotate inward, and the cavity wall of the base cavity 4 is provided with a locking slot 32 that can cooperate with the corresponding locking block 31 to lock. The front end of the seat plate 21 is provided with a leg pedal 24 that can be turned upward relative to it, and the convex ring 22 is also provided with a leg pedal 24 that is connected with the leg pedal 24 and can be linked with the leg pedal 24 to drive the card when the leg pedal 24 is turned up. The transmission component 5 in which the block 31 is disengaged from the card slot 32 . The convex ring 22 on the seat plate 21 can be rotated in the base cavity 4 of the base 1. When the convex ring 22 is located in the base cavity 4, the clamping block 31 is engaged with the clamping groove 32 on the base 1, and the seat is fixed. When the direction is reversed, the leg pedal 24 is turned up and turned up, and the leg pedal 24 is linked with the transmission component 5 during the upward turning process, so as to realize the separation of the blocking block 31 from the blocking groove 32. When the blocking block 31 is detached from the blocking groove 32 Afterwards, the seat plate 21 can be rotated to reverse the direction. The entire reversing process does not require disassembling the seat body 2 from the frame 10, and the operation is very convenient and quick. Moreover, the leg pedals 24 are used to support the legs of infants and young children, so that the infants and young children can ride comfortably. When the seat reversal is required, in order to prevent the leg pedals 24 from interfering with the frame 10 when the seat body 2 is rotated, the leg pedals 24 must be rotated upwards. Turning up, in the present invention, through the linkage between the leg pedal 24 and the transmission component 5, the driving block 31 and the clamping slot 32 are unlocked during the process of turning up the leg pedal 24, which is very cleverly designed. When changing direction, hold the back side of the seat with one hand, turn up the leg pedal 24 with the other hand, and then turn it around. The whole process is completed in one go, and the operation is very simple and fast.

As shown in FIG. 3 to FIG. 7 , the transmission component 5 includes a sliding block 51 arranged in the convex ring 22 and capable of lateral movement. When the leg pedal 24 is turned up, the cable 50 can pull the sliding block 51 to slide. The sliding block 51 is provided with an inclined oblique hole 53, and the clamping block 31 is provided with a slanted hole 53 that penetrates into the inclined hole 53. When the sliding block 51 moves laterally, the pushing column 54 can cooperate with the wall of the inclined hole 53 to make the block 31 move longitudinally. A first return spring 55 is also provided between the sliding block 51 and the seat plate 21 . When the leg pedal 24 is turned up, the pull cable 50 pulls the slider 51 to slide in the lateral direction, and the hole wall of the inclined hole 53 slides relative to the push column 54, thereby driving the push column 54 with the clamping block 31 in the longitudinal direction. When moving, the clamping block 31 is disengaged from the clamping slot 32 during the longitudinal movement. When the clamping block 31 is disengaged from the clamping slot 32, the seat body 2 can be rotated. When the seat body 2 is reversed, the first return spring 55 drives the slider 51 to reset. At this time, the clamping block 31 is reset and reconnected with the clamping slot 32. card lock.

As shown in FIG. 5 and FIG. 7 , the slider 51 is provided with a bar-shaped groove 56 along the moving direction of the slider 51 , the first return spring 55 is arranged in the bar-shaped groove 56 , and the The slider 51 is provided with a first abutting portion 57 that abuts against one end of the first return spring 55 , and the seat plate 21 is provided with a first abutting portion 57 that protrudes into the strip groove 56 and abuts the other end of the first return spring 55 . The second abutting portion 23 .

As shown in FIGS. 2 , 3 and 9 , the opening position of the base cavity 4 is further provided with a block 31 that can still resist when the leg pedal 24 is turned up to the limit position to prevent the protruding ring 22 from passing from the base cavity 4 . With the convex edge 8 taken out, the transmission component 5 also includes an operating belt 52 connected to the slider 51 and extending to the outside of the seat plate 21 and capable of pulling the slider 51 to move the blocking block 31 to the inside of the convex edge 8 . When the leg pedal 24 is turned up to the limit position, the blocking block 31 is disengaged from the blocking groove 32, and the rotation of the seat plate 21 can be realized, but at this position, the blocking block 31 is still blocked by the convex edge 8 at the opening position of the base cavity 4, so that the The convex ring 22 cannot be taken out upwards from the base cavity 4 , so that the seat plate 21 can be rotated more stably, and the operating seat body 2 can be prevented from being pulled upward by mistake when the seat body 2 is rotated. When the seat body 2 needs to be disassembled from the frame 10 , the block 31 can be moved to the inner side of the raised edge 8 by simply pulling the slider 51 through the operating belt 52 . After the inner side, the convex edge 8 no longer resists the blocking block 31, the convex ring 22 can be taken out upward, and the seat body 2 can be disassembled. Therefore, the pulling of the slider 51 by the pulling cable 50 and the operating belt 52 are two independent operations, which make the seat body 2 move smoothly when changing directions, and also make the separation operation of the seat body 2 and the base 1 possible. Very convenient and very cleverly designed.

As shown in Figure 1, Figure 10 and Figure 11, the seat body 2 further includes a seat front rod 25, the lower end of the seat front rod 25 is rotatably connected to the front end of the seat plate 21, and the seat front rod 25 is provided with There is a sliding sleeve 26 which can slide relative to the sliding sleeve 26 and the rear side of the seat plate 21 is provided with a seat rear rod 27 which is hinged with the two. Therefore, the side cloth cover and the sunshade canopy of the stroller can be arranged on the seat instead of being arranged on a larger frame, which can save materials and reduce costs. Moreover, the seat body 2 can also be folded. When folded, the seat front rod 25 and the seat rear rod 27 rotate relative to the seat plate 21, and the sliding sleeve 26 slides on the seat front rod 25, which is very convenient and quick to fold.

As shown in Figure 1, Figure 10 and Figure 11, the sliding sleeve 26 is also rotatably connected with a handrail 28, the upper end of the handrail 28 is connected with a U-shaped front handrail 29, and the lower end of the handrail 28 is connected to The rear end of the seat plate 21 is provided with an armrest link 20 that is hinged with the two, the upper end of the seat front bar 25 is connected with a seat upper bar 2a that can rotate relative to it, and the rear end of the seat plate 21 is also provided with a A backrest 2b that can be rotated relative to it. Therefore, when the seat body is folded, the front armrest 29 can be folded along with it, and the front armrest 29 does not need to be disassembled, and the operation is more convenient. When folding, push the seat upper rod 2a forward and press down, the seat front rod 25 rotates relative to the seat plate 21, the upper ends of the armrest link 20 and the seat rear rod 27 move to the rear side, and the sliding sleeve 26 is on the seat front rod 25. When sliding, the armrest bar 28 rotates relative to the seat front bar 25 to realize the following folding of the front armrest 29 . The entire folding process does not need to disassemble the front armrest 29, which is very simple and quick, and the entire seat is small in size after being folded.

After the seat of the present invention is installed on the stroller, when the stroller needs to be folded, the seat body 2 is folded first, and then the frame is folded. The folding of the seat body 2 is performed independently of the folding of the vehicle body frame 10 .
