Description
Technical field
The utility model relates to a kind of locking structure more particularly to a kind of guardrail locking structures of medical bed, while also relating to
And the guardrail using the locking structure.
Background technique
The two sides of usual medical bed are mounted on guardrail, for preventing patient from falling from bed, while for the ease of patient
It goes to bed, guardrail is typically all to be made into the activity form that can be risen or swing.Such as Patent No.: being disclosed in 201520700561.2
A kind of guardrail applied to medical bed, cross bar (10) bottom of the guardrail are provided with one at the position of the connecting rod (20)
Mounting base (11), one is movably set on the mounting base (11) can stretch out the external bolt (12) of mounting base (11), simultaneously
Mounting base (11) is internally provided with the control switch (13) for driving the bolt (12) to move up and down, the control switch (13)
The other end extends the outside of the mounting base (11), is provided with card adapter plate (22) on the connecting rod (20) of the neighbouring mounting base (11),
The compatible blocked hole (220) with the bolt (12) is offered on the card adapter plate (22).Right this locking structure is still deposited
In following defect: 1, it is for a long time using rear reliability inadequate, since the cooperation between bolt 12 and blocked hole 220 is crossbeam and company
Bar is swung up rear bolt 12 and cooperates with card adapter plate, and card adapter plate forces bolt 12 to shrink together with control switch 13, that is to say, that
Bolt 12 needs to move up and down, and bolt is to be movably installed in mounting base 11 and need to connect with control switch,
Therefore, frequently the flexible installation that will cause bolt is insecure for bolt, and bolt is easy to appear disengaging, to cause lockout failure；
2, in order to save cost, above-mentioned structure is realized and also to facilitate, the mounting base of current most medical bed is modeling
Expect material, control switch and bolt are also plastic material and integrated molding, just bolt and control switch can be made effectively to connect in this way
It connects, and wears so more seriously, service life is lower.3, current bolt be it is naked be exposed on the external, it is also desirable on connecting rod
Be arranged card adapter plate, total is huger, it is naked be exposed on the external to be easy to cause accidentally touch, in turn result in its damage.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of guardrail locking structure of medical bed, the locking knots
Structure it is structurally reasonable, reliability is higher, and the service life is longer.
Another technical problem to be solved in the utility model is: a kind of guardrail locking structure of medical bed is provided, it should
Guardrail has used locking structure, and the locking reliability of guardrail is higher, and the service life is longer.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of guardrail locking structure of medical bed, institute
It states locking structure to be installed between the upper pillar of guardrail and one of support tube, be hinged between upper pillar and support tube,
The locking structure includes the handle set for being installed on pillar bottom, and hand moving up and down is movably installed on the handle set
The inside of handle, the upper pillar is equipped with the axially extending locking spring plate of elastically deformable, and the handle moves up and down drive
Locking spring plate switches between separation station or locking station, and one end of the locking spring plate is fixing end and is fixed on pillar
Inside, the other end of locking spring plate is movable end and fixes with handle, and lock pin holes are provided on the locking spring plate, described
The upper end of support tube is fixed with lock pin corresponding with lock pin holes, and the bottom of the upper pillar is provided with the item for facilitating lock pin beat
Shape avoid holes, the lock pin extend upward through bar shaped avoid holes, and the locking spring plate lock pin and lock pin holes when locking station are inserted
Assembly close, the locking spring plate when separate station lock pin and lock pin holes disengaging, between the locking spring plate and upper pillar or
Dynamic clamping head and quiet clamping head is provided between handle and upper pillar, the elastic force of the dynamic clamping head and quiet clamping head, which acts on locking spring plate or handle, to be made to lock
Determine elastic slice and is in locking station.
As a preferred solution, the hole edge of the lock pin holes protrudes upward to form hole along convex extension part.
As a preferred solution, the dynamic clamping head and quiet clamping head is Lock spring, and one end of Lock spring is set in hole edge
On convex extension part, the other end is pressed in pillar in advance.
As a preferred solution, spring installation is also detachably equipped with by the first fastener in the upper pillar
Set, the other end of the Lock spring are installed in spring installation set.
As a preferred solution, ladder counterbore is provided on the upper pillar, first fastener is that bolt is tight
Firmware, the bolt fastener are installed in ladder mounting hole.
As a preferred solution, the locking spring plate includes the elastic sheet body of strip, is arranged in the elastic sheet body
There is strengthening segment, for the strengthening segment close to movable end, the two sides of the strengthening segment are provided with the flanging being folded upward at, the locking pin
Hole is located in strengthening segment.
As a preferred solution, the axial ends of the handle set passes through the second fastener and is fixed on pillar
Bottom, position corresponding with the second fastener is provided with the evacuation pit to arch upward upwards in the elastic sheet body.
As a preferred solution, the movable end of the locking spring plate and handle fixed form are as follows: the locking spring plate
There are two mounting hole, the upper end of the handle is provided with the clamping portion being engaged by clamping in insertion mounting hole with it for upper setting.
After above-mentioned technical proposal, the effect of the utility model is: the locking structure is utilized and is installed in pillar
The locking elastic in portion, and locking spring plate is driven by handle in separation station and locking Switch of working position, and set on the locking spring plate
