[ detailed description ] embodiments

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1 to 10, a stay bar assembly 6 of a walker comprises an upper stay tube 61 and a lower stay tube 62, wherein the lower stay tube 62 is slidably connected with the upper stay tube 61, a height adjusting device is arranged between the upper stay tube 61 and the lower stay tube 62, the height adjusting device comprises a plurality of locking holes 641 arranged on the lower stay tube 62 and a locking pin hole 642 arranged on the upper stay tube 61, a locking pin capable of moving transversely and simultaneously engaging with the locking pin hole 642 and the locking hole 641 to lock the upper stay tube 61 and the lower stay tube 62 is arranged in the upper stay tube 61, and a driving part 644 capable of driving the locking pin 643 to engage with the locking pin hole 642 and the locking hole 641 or driving the locking pin 643 to disengage from the locking hole 641 is arranged in the upper stay tube 61. When the height of the stay bar assembly 6 needs to be adjusted, the driving part 644 drives the locking pin 643 to be separated from the locking hole 641, at this time, the upper supporting tube 61 can slide relative to the lower supporting tube 62, so that the height adjustment of the stay bar assembly 6 is realized, after the height adjustment of the stay bar assembly 6 is in place, the driving part 644 drives the locking pin 643 to be simultaneously clamped with the locking pin hole 642 and the locking hole 641, at this time, the upper supporting tube 61 and the lower supporting tube 62 are locked, therefore, the driving part 644 drives the locking pin 643 to transversely move to realize the height adjustment of the stay bar assembly 6, the operation is more convenient and faster, the clamping stagnation cannot occur, the structure is simple, the assembly is convenient, and the cost is low.

As shown in fig. 3 to 9, a fixing block 645 is disposed in the upper supporting tube 61, a transverse hole 646 is disposed on the fixing block 645, the locking pin 643 is disposed in the transverse hole 646, the driving member 644 includes a driving spring 6441 disposed in the transverse hole 646 and capable of pushing the locking pin 643 to move transversely and engage with the locking hole 641, the driving member 644 further includes a driving block 6442 capable of moving up and down along the upper supporting tube 61, an inclined surface 6443 capable of pushing the locking pin 643 to move transversely and compress the driving spring 6441 when the driving block 6442 moves longitudinally is disposed on the driving block 6442, and an operating sleeve 6444 connected to the driving block 6442 and capable of driving the driving block 6442 to move longitudinally is disposed on the upper supporting tube 61. When the height of the stay bar assembly 6 needs to be adjusted, the upper supporting tube 61 and the lower supporting tube 62 need to be unlocked firstly, the operating sleeve 6444 is pulled upwards, the driving block 6442 is carried upwards, the inclined surface 6443 on the driving block 6442 touches the locking pin 643, so that the locking pin 643 is pushed to move transversely, the locking pin 643 retreats from the locking hole 641, the upper supporting tube 61 and the lower supporting tube 62 are unlocked, the driving spring 6441 is compressed, the upper supporting tube 61 and the lower supporting tube 62 can slide relatively, when the upper supporting tube 61 and the lower supporting tube 62 slide to a proper position, the operating sleeve 6444 is released, the driving block 6442 descends, the inclined surface 6443 on the driving block 6442 does not abut against the locking pin 643 any more, the driving spring 6441 is stretched again to push the locking pin 643 to slide transversely, the locking pin 643 is engaged with the other locking hole 641, and the height adjustment and locking of the stay bar assembly 6 are realized, the whole operation process is very simple and quick.

As shown in fig. 3, 5 and 10, a bound spring 63 is provided between the upper support tube 61 and the lower support tube 62, and an unlock holding portion 65 that is engageable with the operating sleeve 6444 to hold and disengage the lock pin 643 from the lock hole 641 is provided on the upper support tube 61. When the unlocking holding portion 65 is engaged with the operating sleeve 6444, the operating sleeve 6444 holds the position of the driving block 6442, the inclined surface 6443 of the driving block 6442 abuts against the locking pin 643 to hold the locking pin 643 and the locking hole 641 in a disengaged state, at this time, the upper support tube 61 and the lower support tube 62 are unlocked and held in an unlocked state, at this time, the upper support tube 61 and the lower support tube 62 can slide relative to each other, and the bouncing spring 63 is provided between the upper support tube 61 and the lower support tube 62, so that when an infant sits on a seat pocket in the seat frame 5 to perform a standing and squatting motion, the upper support tube 61 moves up and down, as if bounced on a trampoline, the baby walker becomes an infant amusement tool.

As shown in fig. 3, the unlock holding portion 65 includes an elastic barb provided on the upper supporting tube 61 and capable of being pressed, and after the operation sleeve 6444 pulls the driving block 6442 to disengage the locking pin 643 from the locking hole 641, the elastic barb catches on the operation sleeve 6444 to prevent the operation sleeve 6444 from sliding relative to the upper supporting tube 61. When the elastic barbs hook the operating sleeve 6444, the position of the operating sleeve 6444 is fixed, the position of the driving block 6442 is also fixed, the inclined surface 6443 on the driving block 6442 always abuts against the locking pin 643, at this time, the driving spring 6441 is kept in a compressed state, and the locking pin 643 and the locking hole 641 are kept in a disengaged state, so that the upper supporting tube 61 and the lower supporting tube 62 can slide relatively, and thus, when an infant sits in the seat frame 5 to perform a standing and squatting motion, the walker is in a fun mode like bouncing on a trampoline.

As shown in fig. 5, 8 and 9, a pressing spring 6445 is disposed between the driving block 6442 and the fixing block 645. The jacking spring 6445 jacks the driving block 6442 downwards, so that when the upper supporting pipe 61 and the lower supporting pipe 62 are unlocked, a certain pulling force needs to be applied to the operating sleeve 6444 to unlock the upper supporting pipe, unlocking of the locking pin 643 caused by misoperation of the driving block 6442 is avoided, and safety is ensured. When the elastic barb hooks the operating sleeve 6444, the pressing spring 6445 is in a compressed state, and when the upper supporting tube 61 and the lower supporting tube 62 need to be locked, the elastic barb is pressed, and when the elastic barb hooks no longer hooks the operating sleeve 6444, the pressing spring 6445 ensures that the driving block 6442 descends quickly, so that the locking pin 643 can be quickly clamped with the locking hole 641.

As shown in fig. 5 and 9, a drawbar 6446 is integrally formed on the driving block 6442, the upper end of the drawbar 6446 is connected with an operating sleeve 6444, and the driving block 6442 can pass through the fixing block 645 and the locking pin 643. The operating sleeve 6444 pulls the driving block 6442 upward by the pull rod 6446 so that the driving block 6442 can smoothly push the locking pin 643 to slide laterally to be disengaged from the locking hole 641. Of course, a structure in which a cable is provided between the driving block 6442 and the operating sleeve 6444 may be employed to pull the driving block 6442 upward.
