The locking tongue brake 25 can be connected to the lower end surface of the seat plate 21 so as to be relatively movable forward and backward. The locking tongue brake 25 is connected to the locking tongue 23 through a locking tongue traction line 251. When the locking tongue brake 25 pulls the locking tongue 23 through the locking tongue traction line 251, the locking tongue 23 can be completely accommodated in the locking tongue accommodating groove 221. A locking block 27 is provided on the lower end surface of the seat plate 21. At least two lower grooves 32 are provided on the upper end surface of the seat mounting base 30. The locking block 27 is engaged in the lower groove 32.
[0040] Furthermore, the frame 10 includes left and right side brackets, the support rod 11 is arranged between the left and right side brackets, and the bottom of the seat mounting base 30 is provided with a slot 33 matching the support rod 11, and the support rod 11 is clamped in the corresponding slot 33 of the seat mounting base 30.
[0041] Furthermore, the seat shaft 22 is provided with a wire collection device 26, and the bottom of the wire collection device 26 is provided with a plurality of single-line channels 261 corresponding to the lock tongue receiving groove 221. The wire collection device 26 is provided with a bus channel 262 along the Y-axis direction, and the bottom of the bus channel 262 is connected with the plurality of single-line channels 261, and the top of the bus channel 262 passes through the upper end surface of the seat plate 21, and the upper end surface of the seat plate 21 is connected to the lock tongue brake member 25 at the top of the bus channel 262. A downwardly recessed lock tongue wire groove 211 is provided in between, one end of the lock tongue wire groove 211 is communicated with the top of the bus channel 262, one end of the lock tongue traction wire 251 is connected to the lock tongue 23, and the other end passes through the single-line channel 261 and the bus channel 262 and then follows the lock tongue wire groove 211 to be connected to the lock tongue brake 25. The lock tongue traction wire 251 is wired in the lock tongue wire groove 211, which can make the upper end surface of the seat plate 21 smoother and will not be uneven due to the existence of the lock tongue traction wire 251.
[0042] Furthermore, in order to allow the lock tongue traction line 251 to enter the lock tongue wire groove 211 more smoothly from the bus channel 262, a pulley 263 is set at the connection between the bus channel 262 and the lock tongue wire groove 211. One end of the lock tongue traction line 251 is connected to the lock tongue 23, and the other end passes through the single-line channel 261 and the bus channel 262, bypasses the pulley 263, and follows the lock tongue wire groove 211 to connect with the lock tongue brake 25.
[0043] Furthermore, an upper groove 212 for accommodating a locking block 27 is provided on the lower end surface of the seat plate 21, one end of the locking block 27 is placed in the upper groove 212, and the locking block 27 is connected to the top wall of the upper groove 212 through a second return spring 28. Under the action of the second return spring 28, the upper end of the locking block 27 is located in the upper groove 212 of the seat plate 21, and the lower end is located in the lower groove 32 of the seat mounting base 30 of the frame 10, so that the seat 20 cannot rotate relative to the frame 10, and the two are in a relatively locked state.
[0044] When in use, the moving lock tongue brake 25 pulls the lock tongue 23 through the lock tongue pulling line 251, so that the lock tongue 23 compresses the first return spring 24 until the lock tongue 23 is completely accommodated in the lock tongue accommodating groove 221. At this time, the seat plate 21 is raised, and the seat plate 21 drives the seat shaft 22 to move upward. The part where the lock tongue 23 is installed on the seat shaft 22 moves to the through hole 221 of the seat shaft 22. When the seat plate 21 is raised until the locking block 27 is disengaged from the lower groove 32 of the seat mounting base 30, the seat plate is rotated. 21, the seat plate 21 is reversed. After the reversal, the locking block 27 of the lower seat plate 21 is engaged with the corresponding lower groove 32, and the position of the seat shaft 22 on which the locking tongue 23 is installed moves to the outside of the through hole 221 of the seat shaft 22, and the locking tongue brake 25 is released to reset it. The locking tongue traction line 251 is relaxed, and the locking tongue 23 is popped out from the locking tongue accommodating groove 221 under the action of the first reset spring 24 and is stuck to the bottom of the seat mounting base 30, thereby limiting the seat 20 from detaching from the seat mounting base 30.
[0045] In another embodiment, the seat plate 21 is provided with a locking block brake 29 for controlling the locking block 27 to enter or escape from the lower groove 32. The locking block brake 29 is connected to the lower end surface of the seat plate 21 so as to be movable forward and backward relative to each other. The locking block brake 29 is connected to the locking block 27 via a locking block traction line 291.
[0046] Furthermore, the upper end surface of the seat plate 21 is provided with a through hole 213 communicating with the upper groove 212, one end of the locking block traction line 291 is connected to the locking block brake 29, and the other end passes through the through hole 213 from top to bottom and is connected to the locking block 27.
[0047] When in use, the locking block brake 29 is moved, and the locking block 27 can be pulled upward by the locking block traction line 291, so that the lower end of the locking block 27 is separated from the lower groove 32, and the locking block 27 is completely retracted into the upper groove 212. At this time, the seat 20 can rotate 360 degrees around the Y axis relative to the frame 10. When it is rotated to the required position, the locking block brake 29 is released, and the locking block 27 moves downward under the action of the second return spring 28, so that the locking block 27 is again engaged with the upper groove 212 and the lower groove 32 at the same time, and the seat 20 is oriented to the facing position. Because the locking block 27 is set on the seat plate 21, after the locking block 27 is completely retracted into the upper groove 212 of the seat plate 21, the seat plate 21 can be directly rotated without pushing other parts of the seat 20, so that the operation is very convenient.
[0048] Furthermore, in the present embodiment, the seat 20 is set to have two orientation positions, namely, forward and backward. In the present embodiment, preferably, the lower grooves 32 are symmetrically arranged with the Y axis as the center, the upper groove 212 is arranged with one, and the locking block 27 is also arranged with one, and when the seat faces forward, the upper groove 212 corresponds to the position of one of the lower grooves 32, and when the seat faces backward, the upper groove 212 corresponds to the position of another lower groove 32, so that when the seat 20 is in the locked position, the upper end of the locking block 27 is clamped into the upper groove 212, and the lower end is clamped into any one of the lower grooves 32. That is, only when the seat 20 is in the forward or backward position, the locking block 27 can be clamped with the upper groove 212 and the lower groove 32 at the same time, that is, the seat 20 can only be positioned in the forward or backward position. In other embodiments, multiple directions can also be set as needed, that is, multiple upper grooves 212 and lower grooves 32 in different positions are set.
[0049] Furthermore, a locking block wire groove 214 recessed downward is provided at the upper end of the seat plate 21 between the locking block brake 29 and the locking block 27, one end of the locking block wire groove 214 is communicated with the through hole 213, one end of the locking block traction wire 291 is connected to the locking block brake 29, and the other end is routed along the locking block wire groove 214 until the other end of the locking block traction wire 291 passes through the through hole 213 and is connected to the locking block 27. The locking block traction wire 291 is wired in the locking block wire groove 214, which can make the upper end surface of the seat plate 21 smoother and will not be uneven due to the existence of the locking block traction wire 291.
[0050] In one embodiment, the seat plate 21 is provided with a flat groove 215, the locking tongue wire groove 211 and the locking block wire groove 214 are both arranged in the flat groove 215, the locking tongue wire groove 211 and the locking block wire groove 214 are both formed by the bottom wall of the flat groove 215 being recessed downward, a top cover plate 216 is connected to the seat plate 21 and arranged in the flat groove 215, and the upper end surface of the top cover plate 216 is flush with the upper end surface of the seat plate 21. In this way, the lower end surface of the top cover plate 216 covers the locking tongue wire groove 211 and the locking block wire groove 214, thereby preventing the locking block traction line 291 from coming out of the wire groove during use, and the top cover plate 216 will not affect the flatness of the upper end surface of the seat plate 21.
[0051] After adopting the above technical scheme, the beneficial effects of the utility model are: there is no need to remove the seat from the frame, the direction can be changed by rotating the seat itself, which is convenient and practical, and the seat can also be disassembled for easy transportation and cleaning. The reversible baby stroller is more convenient for taking care of the baby in the car and is more practical.
