[ detailed description ] embodiments

The utility model is further described below with reference to the accompanying drawings:

as shown in fig. 1 to 4, a locking device 1 includes a vertical support rod 20 and a sliding seat 11 slidably connected to the support rod 20 and used for connecting a transverse support rod 30, the sliding seat 11 is provided with a locking hole 12, the support rod 20 is provided with a locking rod 13 capable of moving transversely therein to engage with or disengage from the locking hole 12, the sliding seat 11 is provided with a driving assembly capable of driving the locking rod 13 to disengage from the locking hole 12, a first return spring 14 capable of driving the locking rod 13 to return is further provided between the support rod 20 and the locking rod 13, the driving assembly includes a push rod 151 exposed out of the sliding seat 11 and capable of moving transversely to push the locking rod 13 to disengage from the locking hole 12, the sliding seat 11 is further provided with a sliding seat 152 capable of blocking the transverse movement of the push rod 151 and capable of yielding for the transverse movement of the push rod 151 after moving relative to the sliding seat 11, a second return spring 157 capable of driving the sliding seat 152 to return is arranged between the sliding seat 11 and the sliding seat 152, and a positioning member 153 capable of keeping the sliding seat 152 positioned when the sliding seat 152 slides relative to the sliding seat 11 and moves back for the push rod 151 is further arranged between the sliding seat 11 and the sliding seat 152. The slide seat 152 is provided in the slide seat 11, and in an initial state, the slide seat 152 can block the push rod 151 from moving laterally, so that the push rod 151 cannot be pressed without first pressing the slide seat 152, and even if an infant touches the push rod 151, the locking lever 13 cannot be pushed to unlock, thereby preventing the infant from misoperation and ensuring safety. When the unlocking is needed, only the sliding seat 152 needs to be pressed first, and the sliding seat 152 moves away from the pushing rod 151 after sliding relative to the sliding seat 11, so that the pushing rod 151 can move laterally, and when the sliding seat 152 slides relative to the sliding seat 11 and moves away from the pushing rod 151, the positioning member 153 can keep the position of the sliding seat 152, so that the sliding seat 152 is always in a state of moving away from the pushing rod 151, and at the moment, a user can release the pressing on the sliding seat 152 to release the hand to press the pushing rod 151, so that the sliding seat 152 and the pushing rod 151 do not need to be pressed simultaneously, and the unlocking operation is more convenient and simpler.

As shown in fig. 2 and fig. 3, the positioning element 153 includes a positioning hole 1531 disposed on the sliding seat 152, a positioning pin 1532 capable of engaging with the positioning hole 1531 and being pushed by the pushing rod 151 to disengage from the positioning hole 1531 is disposed in the sliding seat 11, and a third return spring 1533 capable of returning the positioning pin 1532 is disposed between the sliding seat 11 and the positioning pin 1532. After the sliding seat 152 slides relative to the sliding seat 11, the positioning hole 1531 on the sliding seat 152 is aligned with the positioning pin 1532, the third return spring 1533 pushes the positioning pin 1532 to return to engage with the positioning hole 1531, the position of the sliding seat 152 is positioned at this time, the push rod 151 can be pressed at this time, the push rod 151 pushes the locking rod 13 to disengage from the locking hole 12 on the sliding seat 11 in the process of transverse movement, and also pushes the positioning pin 1532 to disengage from the positioning hole 1531, so that the sliding seat 152 can return. When the pushing rod 151 pushes the locking rod 13 out of the locking hole 12, a force is applied to the sliding seat 11, so that the sliding seat 11 can slide relative to the supporting rod 20, and when the pushing rod 151 is released, the pushing rod 151 is reset by the fourth return spring 156, and the positioning pin 1532 is reset by the third return spring 1533.

As shown in fig. 2 and 3, the slide base 152 is provided with a relief groove 154 for the push rod 151 to move inside, and when the positioning pin 1532 is engaged with the positioning hole 1531, a spacing space 155 is formed between an upper inner wall 154a of the relief groove 154 and an upper outer wall 151a of the push rod 151. Therefore, when the push rod 151 pushes the locking lever 13 and the positioning pin 1532, once the positioning pin 1532 is pushed out of the positioning hole 1531, the sliding seat 152 moves under the action of the second return spring 157, so that the upper inner wall 154a of the relief groove 154 on the sliding seat 152 contacts with the upper outer wall 151a of the push rod 151, and the positioning hole 1531 and the positioning pin 1532 are misaligned, which can ensure that the positioning pin 1532 cannot be inserted into the positioning hole 1531 during the process of releasing the push rod 151 and resetting the push rod 151 and the sliding seat 152, and ensure the reliability of the structure.

As shown in fig. 2 and 3, a fourth return spring 156 capable of returning the push rod 151 is further disposed between the sliding seat 11 and the push rod 151.

As shown in fig. 1 to 3, the locking device further includes a connecting seat 16 capable of connecting the cross rod 30, the sliding seat 11 is provided with an open slot 17 into which the connecting seat 16 is transversely inserted, the sliding seat 11 is provided with a locking hole 181 communicated with the open slot 17, the connecting seat 16 is provided with a locking pin 182 capable of moving therein and engaging with or disengaging from the locking hole 181, the connecting seat 16 is provided with a button 183 capable of driving the locking pin 182 to move, and a fifth return spring 184 capable of returning the locking pin 182 is disposed between the connecting seat 16 and the locking pin 182. The connecting seat 16 can be taken out from the sliding seat 11, so that the cross rod 30 on the bed guardrail can be separated from the supporting rod 20, and the user can conveniently detach the enclosing cloth on the bed guardrail for cleaning.

As shown in fig. 2, a first inclined surface 183a is provided on the button 183, and a second inclined surface 182a matched with the first inclined surface 183a in an abutting manner is provided on the latch pin 182. When the cross bar 30 needs to be separated from the support bar 20, the button 183 is pressed, the first inclined surface 183a pushes the second inclined surface 182a, so that the locking pin 182 is separated from the locking hole 181 of the sliding seat 11, and at this time, the connecting seat 16 can be taken out of the sliding seat 11, and the cross bar 30 is separated from the support bar 20.

As shown in fig. 2, the supporting rod 20 includes a rod body 201 and a cover body 202 connected to an upper end of the rod body 201, and the cover body 202 is provided with a rib 203 capable of preventing the connecting seat 16 from being removed from the opening groove 17 when the locking hole 12 is engaged with the locking lever 13. When the sliding seat 11 is locked on the supporting rod 20, the rib 203 blocks the connecting seat 16, and at this time, even if the infant touches the button 183, the connecting seat 16 cannot be separated from the sliding seat 11, so that the transverse rod 30 cannot be separated from the supporting rod 20, and safety is ensured. When the cross rod 30 needs to be disassembled, the sliding seat 11 and the supporting rod 20 are firstly unlocked, the sliding seat 11 slides downwards for a certain distance, so that the rib 203 does not block the connecting seat 16 any more, and then the button 183 is pressed, so that the unlocking of the connecting seat 16 and the sliding seat 11 can be realized, and the safety is ensured.

As shown in figure 5, the bed guardrail comprises two locking devices 1 as described above, a cross strut 30 is connected between the two sliding seats 11, and the lower end of each support rod 20 is provided with an L-shaped support leg 40 which can be pressed by a mattress. Therefore, the bed guardrail of the utility model can prevent the misoperation of infants, ensure the safety, and can keep the position of the sliding seat 152 when the transverse strut 30 is adjusted downwards after unlocking, thereby freeing hands to operate the push rod 151, and ensuring the unlocking operation to be more convenient and faster.
