DETAILED DESCRIPTION

[0026] The technical scheme of the present application will be further described below in conjunction with the drawings and specific embodiments.

[0027] In the following description, the directions of "front", "rear", "left", "right", "up", "down" and the like are all according to the directions shown in the drawings, i.e., the left direction in the drawings is "front", the right direction is "rear", the up direction is "up", and the down direction is "down". The directions are merely for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application. Figure 5 As shown in the drawings, the stroller of the present embodiment comprises a stroller frame 1, a seat 2, a pull rope 3 and a cloth cover 4.

[0028] Figure 1 The stroller frame comprises a push handle 14, and the seat 2 is arranged on the stroller frame 1. The pull rope 3 is arranged between the seat 2 and the push handle 14, and the cloth cover 4 is arranged on the pull rope 3. The cloth cover 4 and the seat 2 jointly form a seating space for a child to sit on.

[0029] The stroller frame comprises a push handle 14, and the seat 2 is arranged on the stroller frame 1. The pull rope 3 is arranged between the seat 2 and the push handle 14, and the cloth cover 4 is arranged on the pull rope 3. The cloth cover 4 and the seat 2 jointly form a seating space for a child to sit on.

[0030] As shown in the drawings, Figure 1 , Figure 2 , Figure 4 and Figure 7As shown, one end of the pull rope 3 is arranged at a position close to the front end of the seat 2, and the other end of the pull rope 3 is arranged at a position close to the rear end of the seat 2, and the pull rope 3 is movably wound around the push handle 14.

[0031] In this embodiment, the push handle 14 comprises a horizontal rod 141 extending in the left-right direction, and side rods 142 extending forward from the left and right ends of the horizontal rod 141 respectively, and the pull rope 3 is movably wound around the side rods 142.

[0032] When the stroller is in use, the pull rope 3 is in a tensioned state, so that the cover 4 is straightened to support the child sitting in the seating space, and the appearance of the stroller is neat and beautiful. However, after the stroller is used for a long time, the pull rope 3 is prone to relaxation, so that the cover 4 cannot be straightened.

[0033] Based on this, the stroller further comprises a tensioning mechanism, which can adjust the tightness of the pull rope 3 through the tensioning mechanism. Specifically, the tensioning mechanism comprises an adjusting member 5, which is arranged on the stroller frame in an adjustable position, and the adjusting member 5 cooperates with the pull rope 3, so that when the adjusting member 5 moves to adjust the position relative to the stroller frame, the pull rope 3 can be moved synchronously to change the length of the pull rope 3, thereby adjusting the tightness of the pull rope 3.

[0034] Specifically, as shown in Figure 5 , Figure 6 , Figure 8 and Figure 9 , the stroller frame is provided with a through hole 142a, and after the pull rope 3 is sleeved on the adjusting member 5, the two ends thereof are simultaneously passed through the through hole 142a and extend downward to be arranged at the front end and the rear end of the seat 2 respectively. When the adjusting member 5 moves relative to the stroller frame, the length of the pull rope 3 between the through hole 142a and the adjusting member 5 can be changed, thereby achieving the effect of adjusting the tightness of the pull rope 3.

[0035] The cooperation between the adjusting member 5 and the pull rope 3 is that the adjusting member 5 is provided with a slot 51, and the pull rope 3 is movably arranged in the slot 51, as shown in Figure 5 , Figure 6 , Figure 8 and Figure 9 . Such cooperation makes the pull rope 3 not easy to come out of the slot 51, so as to ensure that the adjusting member 5 moves synchronously with the pull rope 3 when the adjusting member 5 moves relative to the stroller frame.

[0036] In a specific embodiment, the adjusting member 5 is slidably arranged on the stroller frame, and the position of the adjusting member 5 on the stroller frame is adjusted by sliding the adjusting member 5 relative to the stroller frame.

[0037] In this embodiment, the adjusting member 5 is slidably arranged on the side rod 142 in the front-rear direction. The side rod 142 is further provided with a guide groove 142b cooperating with the adjusting member 5, the guide groove 142b extending in the sliding direction of the adjusting member 5, i.e. in the front-rear direction, and the adjusting member 5 is slidably arranged in the guide groove 142b in the length direction of the guide groove 142b, as shown in Figure 5 、 Figure 6 、 Figure 8 and Figure 9 .

[0038] The perforation 142a communicates with the guide groove 142b, and the perforation 142a can be close to the front end of the guide groove 142b, as shown in Figure 5 、 Figure 6 、 Figure 8 and Figure 9 . In this way, when the adjusting member 5 slides backward along the guide groove 142b, the length of the pull rope 3 between the perforation 142a and the adjusting member 5 increases, so that the pull rope 3 is tensioned. Conversely, when the adjusting member 5 slides forward along the guide groove 142b, the length of the pull rope 3 between the perforation 142a and the adjusting member 5 decreases, so that the pull rope 3 is relaxed.

[0039] Of course, the perforation 142a can also be arranged close to the rear end of the guide groove 142b, so that when the adjusting member 5 slides forward along the guide groove 142b, the pull rope 3 is tensioned; and when the adjusting member 5 slides backward along the guide groove 142b, the pull rope 3 is relaxed.

[0040] The tensioning mechanism further comprises a driving member 6, which is rotatably or slidably arranged on the stroller frame, and the driving member 6 cooperates with the adjusting member 5, so that when the driving member 6 rotates or slides relative to the stroller frame, the adjusting member 5 is driven to move to an adjusted position relative to the stroller frame through the cooperation between the driving member 6 and the adjusting member 5.

[0041] The driving member 6 is rotatably arranged on the stroller frame, and the adjusting member 5 is moved relative to the stroller frame by rotating the driving member 6 relative to the stroller frame.

[0042] Specifically, as shown in Figure 5 、 Figure 6 、 Figure 8 and Figure 9 , the driving member 6 can be a screw rod, which is rotatably arranged on the side rod 142 of the push handle 14, and a nut 52 is fixedly arranged in the adjusting member 5, and the screw rod and the nut 52 are connected through thread cooperation. When the screw rod is rotated about its own axis, the nut 52 is driven to move in the axial direction of the screw rod, thereby driving the adjusting member 5 to move in the same direction to an adjusted position.

[0043] In other embodiments, the driving member 6 is slidably arranged on the stroller frame, and the driving member 6 cooperates with the adjusting member 5 through a slope.

[0044] The structure of the stroller frame is not limited to the structure shown in the embodiment.

[0045] Specifically, as shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the stroller frame further comprises a front support 11, a rear support 12 and a push rod 13. The lower part of the front support 11 is provided with the front wheel assembly 7, and the lower part of the rear support 12 is provided with the rear wheel assembly 8. The upper part of the rear support 12 is rotationally connected with the upper part of the front support 11. The lower part of the push rod 13 is slidingly connected with the upper part of the front support 11, so that the push rod 13 is slidingly arranged along the length extension direction of the front support 11, and the push handle 14 is fixedly arranged at the upper end of the push rod 13. In this way, the child stroller can also be folded. When the child stroller is folded, the push rod 13 slides and approaches the front support 11, and the front support 11 and the rear support 12 are relatively rotated and approached.

[0046] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the rear part of the seat 2 is rotationally connected with the upper part of the front support 11. The stroller frame further comprises a connecting rod 15, one end of the connecting rod 15 is rotationally connected with the upper part of the rear support 12, and the other end of the connecting rod 15 is rotationally connected with the front part of the seat 2. In this way, a four-bar linkage mechanism is formed between the front support 11, the seat 2, the connecting rod 15 and the rear support 12, so that when the rear support 12 is rotated relative to the front support 11, the seat 2 can be synchronously rotated relative to the front support 11. In this way, during the unfolding or folding operation of the child stroller, the rotation of the rear support 12 can be linked to rotate the seat 2 relative to the front support 11, and the seat 2 does not need to be separately operated to rotate relative to the front support 11, so that the folding and unfolding operation of the child stroller is convenient.
