Description
Technical field
The utility model relates to locking device more particularly to hospital bed guardrail locking devices.
Background technique
The tight mechanism of hospital bed guardrail locking device on existing market generally use locking pin insertion locked groove locking mode with
Lock sheet clamping lock shaft block locking mode.
Usually using the locking scheme of locking pin insertion locked groove, handle cylinder base is fixed on guardrail transverse bar by the program,
Locked groove seat is fixed on fence upright, handle cylinder slides up and down in handle cylinder base, and locking pin is fixed on handle cylinder bottom
End, by the downward pressing handle cylinder of spring, is caught in locking pin in locked groove and reaches locking work after guardrail rotation is risen in place
With；With the upward gripping handles cylinder of hand, locking pin is set to be detached from locked groove, to reach unlock guardrail.When program guardrail rises, lock pin
It can not need manual-up handle cylinder that can just make hospital bed guardrail locking device tight voluntarily in dropping place to locked groove.Above scheme is another
Kind implementation are as follows: handle cylinder base is fixed on column, and locking pin and handle cylinder are installed in handle cylinder base, with column
It is rotated together around column bottom end fulcrum, after guardrail rotation is risen in place, locking pin is compressed by spring inwards, make to lock pin card
Enter to be mounted on to reach in the lockhole of lathe bed corresponding position locking effect；It is pulled outwardly handle cylinder with hand, locking pin is made to be detached from lockhole, from
And achieve the purpose that unlock guardrail.Program retaining mechanism is mounted on guardrail bottom end, inconvenient for operation.
Lock sheet clamping lock shaft block locking mode are as follows: lifting linking member 1 and lifting linking member 2 are fixed on guardrail around its bottom end and pacify
The hinge rotation on seat board is filled, and guardrail baffle is driven to move the lifting for realizing guardrail, two connecting rod and guardrail mounting base together
Plate, guardrail baffle form a parallelogram mechanism.After guardrail rises in place, the lock sheet on divider switch is fixed in bullet
Spring acts on lower clamping and is mounted on the lock shaft of guardrail installation seat plate corresponding position, to lock guardrail；Rotate divider switch by hand
It is detached from lock sheet and lock shaft, can fall guardrail.
The first aforementioned locking mode need to be on guardrail separately plus a set of additional retaining mechanism (including switch handle, locking
Pin, locked groove corresponding with locking pin), production cost is both increased, also affects the globality of guardrail appearance, and for a long time
After use, locking will appear loosening, influence using effect.Second of locking mode be mating to be only applicable to hoisting type guard rail, practical
Narrow range.
