Description

TECHNICAL FIELD

[0001] The utility model relates to a locking device for silent lifting bed guardrail and bed guardrail containing the locking device.

BACKGROUND

[0002] Because the bed is generally higher now, in order to prevent children from falling off the bed, more and more families will set bed guardrails around the bed.

[0003] The common bed guardrail on the market is disclosed in the Chinese utility model patent with the application number CN201520796404.6, which comprises a stand, a lower horizontal rod, an upper horizontal rod, a locking head, a sliding rod and a fence net. The upper horizontal rod is provided with a locking head at both ends. The locking head is located on the outer side of the upper horizontal rod. An installation hole is opened in the locking head. The sliding rod is installed in the installation hole. The locking head slides up and down along the sliding rod. The locking head comprises a switch, a locking piece and a spring. The stand is provided with a recessed slot at the upper part. The recessed slot cooperates with the locking piece. When locking, the switch pushes the locking piece into the recessed slot and clamps it under the elastic force of the spring. When opening the bed, the horizontal unlocking switch is used to move the locking piece out of the recessed slot. The locking piece moves to the guide rail and can be freely slid. The sliding rod is slid down. The fence net is retracted. The safety guardrail can be opened. Although the locking head on this kind of bed guardrail can realize the functions of locking and unlocking the upper horizontal rod, it still has the following problems: first, the locking noise is large. The locking piece and the sliding rod contact and rub when the locking head slides along the sliding rod, which produces noise and easily wakes up the sleeping children. Second, it adopts one-key unlocking form. Only one action can complete the unlocking. Children have the ability to imitate. They can imitate adults to open the lock after observing for many times, which has safety hazards.

[0004] Therefore, the utility model is produced based on the above deficiencies.
