Utility model content

The purpose of this utility model is to provide a kind of Nephrology dept.'s examination couch power-assisted handrails of angle adjustable, have user Just the advantages of, solves the problems, such as that traditional product handrail angle is nonadjustable.

To achieve the above object, the utility model provides the following technical solutions: a kind of Nephrology dept.'s examination couch of angle adjustable Power-assisted handrail, including fixed cylinder, the side of the fixed cylinder are fixedly connected with fixed plate, close one end in the fixed plate Front is rotatably connected to handle, and the intracavitary of the fixed cylinder is fixedly installed with single direction turning mechanism.

The single direction turning mechanism includes fixed lid, and the fixation is covered to be fixedly connected with close to the front at its edge and be led Block, the back side of the fixed cylinder offer guide groove, and fixed cylinder is slidably connected by the outer wall of guide groove and guide block, and the fixed lid is just Fixing axle is fixedly connected in the middle part of face, the outer wall of the fixing axle is fixedly connected with fixed ring, and the outer wall of the fixed ring is solid Surely it is connected with latch, the inner wall of the fixed cylinder is fixedly connected there are two rotation seat, and the opposite face of two rotation seats is fixed to be connected It is connected to rotation axis, the outer wall of the rotation axis is rotatably connected to kelly, close one end on the inside of the rotation seat and kelly Outside offer torsional spring slot, the rotation seat and kelly pass through torsional spring slot and are fixedly connected with torsional spring, lean on the kelly The bottom of its nearly other end and the inside of latch are clamped, and one end of the fixing axle extends to fixed cylinder by the intracavitary of fixed cylinder Outside, the front of the fixed cylinder is fixedly installed with bearing cap, and the inner wall of the bearing cap is fixedly connected with bearing, the axis The inner wall held is fixedly connected with the outer wall of fixing axle.

Preferably, the quantity of the handle is two, and two handles are using the positive vertical centerline of fixed cylinder as axial symmetry Arrangement, and the outer wall of two handles is fixedly connected to Anti-slip cover.

Preferably, the quantity of the latch is no less than 20, and the spacing of two neighboring latch and the kelly other end Size is adapted.

Preferably, the quantity of the torsional spring is two, and two torsional springs are arranged by axial symmetry of the vertical centerline of kelly top surface Column.

Preferably, the quantity of the kelly is no less than three, and each kelly is centered on the center of circle of fixed cylinder front circle Annular array.

Preferably, the other end of the kelly towards fixed cylinder middle bent, and the inside of kelly be shiny surface.

Compared with prior art, the beneficial effects of the utility model are as follows:

One, the utility model is by setting fixed cylinder, handle, latch, kelly and torsional spring, when regulation handle angle, Handle rotation hand-held first, then fixed cylinder rotates, since the kelly other end is towards fixed cylinder middle bent and kelly medial surface The reason of for shiny surface, kelly is outer after the crowded effect of cutting by latch to be moved, and torsional spring is in " energetically " state, crosses previous card Kelly resets after will receive the torque effect that torsional spring is given after tooth, is stuck in the inside of latch again, until after angular adjustment, The outside of kelly keeps existing state constant after being kept out effect by latch, turns so that fixed cylinder is unable to opposite direction It is dynamic, single direction turning mechanism is so mounted on to the side of hospital bed, when regulation handle angle, fixed cylinder can only be towards tailstock Direction rotation, fixed cylinder limit towards head of a bed direction, reach the adjustable purpose of handle angle, use more convenient.

Two, the utility model is by being arranged fixed lid, guide block, guide groove, fixing axle, fixed ring, latch, rotation seat, rotation Axis, kelly, torsional spring, bearing cap and bearing offer through-hole in the side of hospital bed first when installing single direction turning mechanism, Fixing barrel casing is set in through-holes, penetrates fixing axle in the back side of fixed cylinder, and be directed at latch, and kelly is stuck in two neighboring card Between tooth, then fixed plate is mounted on to the inside of hospital bed guardrail, finally by the front installation upper ball cover of fixed cylinder, tool There is the effect that structure is simple, convenient for disassembly and assembly.
