Detailed Description

As shown in fig. 1 and 2, a stroller comprises two symmetrically arranged side brackets 1, each side bracket 1 comprises a handle bar 11, a front connecting rod 13, a rear connecting rod 12, a front foot bar 14, a rear foot bar 15 and a lower connecting rod 16, wherein the tops of the front connecting rod 13 and the rear connecting rod 12 are rotatably connected with the bottom of the handle bar 11, the bottom of the front connecting rod 13, the top of the front foot bar 14 and the top of the rear foot bar 15 are coaxially and rotatably connected, in order to avoid the occurrence of hand clamping, the bottom of the front connecting rod 13 is provided with an arc-shaped section 130, and the arc-shaped section 130 is tangent to the rear foot bar 15 in a frame unfolding state, so that the whole frame is better in streamline.

As shown in fig. 1 and 2, the lower link 16 is rotatably connected at both ends thereof to the front foot bar and the rear link 12, respectively, and in this embodiment, the front foot bar 14, the rear foot bar 15, the lower link 16 and the rear link 12 constitute a four-bar linkage, while the handle bar 11, the front link 13, the rear link 12 and the rear foot bar 15 constitute another four-bar linkage, which is folded by the rear link 12 in a linked manner. The utility model discloses the improvement point lies in the part of handrail before the seat locking mainly, and above interlock structure is only the utility model discloses a preferred mode adopts other interlock modes and does not hinder the implementation the technical scheme of the utility model.

The utility model discloses a be provided with seat 2 between two side supports 1, seat 2 includes two limit poles 22, as shown in fig. 3-5, the front end inboard of both sides pole 22 is provided with L type connecting pipe 27, and is provided with the preceding spreader bar 25 that the tip inserted L type connecting pipe 27 between the two, is provided with torsional spring 21 in the clearance between L type connecting pipe 27 and the preceding spreader bar 25. The advantage of using this structure is that it is easy to assemble, because the L-shaped connecting pipe 27 can be directly sleeved on the side bar 22. The pivoting connection to the front cross brace 25 can of course also be achieved by making a hole directly in the side bar 22, but this is not sufficient to mount the torsion spring 21, since the width of the side bar is limited.

The middle part of the front transverse supporting rod 25 is provided with an armrest mounting seat 26, the rear side of the armrest mounting seat 26 is provided with a pin hole, a slidable locking pin 29 is arranged in the pin hole, and a return spring 291 which is abutted against the locking pin 29 is further arranged in the pin hole.

The side bar 22 is provided with sliding sleeves 23, a rear transverse supporting rod 24 is arranged between the two sliding sleeves 23, the rear transverse supporting rod is provided with a braking part 28, the braking part 28 is provided with a locking groove 280 matched with the locking pin 29, in order to facilitate the insertion of the locking pin 29 into the locking groove 280, the side wall of the locking groove 280 is provided with a notch 281, and the free end of the corresponding locking pin 29 is provided with a guide inclined plane.

As shown in fig. 6 and 7, when the sliding sleeve 23 moves the braking member 28 backward, the locking pin 29 is disengaged from the locking groove 280, and the front armrest 3 is automatically tilted toward the seat 2 by the torsion spring 21. If the braking member 28 returns to the locking position, the front armrest 3 is manually turned reversely, the locking pin 29 enters the locking groove 280 from the notch 281 against the action force of the torsion spring 21, in the process, the return spring 291 is compressed until the locking pin 29 passes through the notch 281, and under the action of the return spring 291, the locking pin 29 naturally extends to enter the locking groove 280, so that locking is realized.

Above is only a preferred mode of handrail before locking, for example also can set up stop pin and reset spring in that side bar 22 is inside, and set up the locking groove on horizontal brace 25 in the front, can realize equally the utility model discloses, only the diameter of horizontal brace is darker before for locking the groove depth degree is not enough, and locking reliability is relatively poor. And because a rear transverse supporting rod 24 is arranged between the two sliding sleeves 23, the rear transverse supporting rod 24 can limit the transitional overturning of the front handrail 3.

As shown in fig. 1 and 6, the front end of the side bar 22 is hinged to the front link 13, and the sliding sleeve 23 has a linkage 17 hinged to the rear link 12, as shown in fig. 8, when folded, the front link 13, the rear link 12 and the rear leg 14 all approach the rear leg 15, and at this time, the linkage 17 pulls the sliding sleeve 23 to slide along the side bar 22, and the side bar 22 rotates around the hinge point with the front link 13. The structure has the advantages that the front handrail 3 can be unlocked when the trolley is folded, and the trolley folding operation is simplified. This configuration is only a preferred embodiment of the present invention, and other configurations for moving the braking member 28 may be employed, or the braking member 28 may be moved manually.

The front handrail 3 is T-shaped, and the bottom of the front handrail is inserted into the handrail mounting seat 26. Typically, the bottom of the front armrest 3 is provided with a snap (not shown), and the corresponding armrest mounting seat 26 is provided with a locking hole matched with the snap for convenient detachment and replacement.

As described above, when the stroller of the present invention is folded, the L-shaped connecting tube 23 moves backward along the side bar 22, so as to drive the braking member 28 to retreat, so that the locking pin 29 exits the pin hole 280, and the front cross brace 25 and the front armrest 3 are turned toward the seat 2 until the front armrest 3 leans against the rear cross brace 24.

When the frame is opened, the front handrail 3 needs to be manually turned reversely, the guide inclined plane slides along the gap 281, the return spring 291 is compressed in the process until the locking pin 29 is inserted into the pin hole 280, and the return spring 291 is reset to realize locking.
