Description

A kind of medical bed guardrail locking device

Technical field

The utility model belongs to a kind of parts of medical bed, relates to a kind of medical bed guardrail locking device.

Background technology

Along with the development of medical science level, medical bed has become the necessary tool for taking rest of people in therapy rehabilitation and treatment tool.But in present medical bed, the lock-up cock of some guardrails is all arranged on the handle of guardrail one end, if user touches lock-up cock because of carelessness, may guardrail will be made to open, guardrail no longer has the effect of protection, easily damages patient; Some guardrails are then due to the relation of locked position, and patient is not easy to open, if patient is badly in need of leaving the bed, its use is very inconvenient again.

Utility model content

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of locking reliability high, opens conveniently medical bed guardrail locking device.

For achieving the above object, technical solution of the present utility model is: a kind of medical bed guardrail locking device, it comprise guardrail latch body, two with guardrail link up with match lock hook, open cover plate, dead bolt and guardrail and link up with; Guardrail hook is fixed on guardrail main body lower end, and guardrail latch body is fixed on the sidewall of bedstead upper end, and after guardrail cuts out, guardrail hook is just to the latching slot of guardrail latch body; Dead bolt is slidably disposed in the latching slot of latch body, and its rear end is fixed on one end of stage clip, and the other end of stage clip is fixed on the aft bulkhead of latching slot; The sidewall of latching slot is fixed with jointed shaft; Two lock hooks are attached on latching slot sidewall respectively, can be arranged on jointed shaft rotatably; Open cover plate and be buckled in latching slot upper surface, both sides, its rear end can be arranged on the jointed shaft two ends of lock hook outer end rotatably; Two projections are stretched out in its two sides, are inserted in respectively in the spacing hole of two lock hook upper ends.

Guardrail hook described above is a L-type structure surrounded by more piece round metal bars; The hook channel opening of lock hook is downward, and the outer face A of the upper wall at hook notch place is downwardly towards the tilted inclined plane of groove, and the inner face B of lower wall is the inclined plane downwardly towards groove outer incline; The corner of upper wall and lower wall is arc lead angle.Like this, when guardrail hook stretches in groove, be easy to slip in hook groove along upper wall, when guardrail hook is retracted outside groove, lower wall plays certain thrust; Arc lead angle does not damage guardrail hook and other parts with lock hook joint.

As long as enforce guardrail, guardrail hook touching dead bolt, compression press spring, dead bolt is along with to latching slot internal contraction, and guardrail hook touches lock hook, and the upper surface heading on latch hook impels latch hook to rotate, open cover plate to rotate up simultaneously, until guardrail hook enters after in lock hook groove, latch hook return, opens cover plate return, guardrail is hooked in lock hook groove, only otherwise trip lock hook, guardrail hook would not depart from lock hook groove, and guardrail reaches positive lock state.When guardrail opened by needs, upwards pull unlatching cover plate, open cap strip is moved lock hook and is upwards rotated, guardrail hook departs from lock hook constraint, and stage clip outwards ejects, and promotes dead bolt outwards movement, dead bolt promotion guardrail hook leaves position during locking, and so far guardrail is opened, and is opening.The utility model structure is simple, and locking reliability is high, opens convenient and swift.
