Description

A kind of sick bed

Technical field

This utility model relates to a kind of sick bed.

Background technology

Backboard lifting hospital bed mainly comprises: the bed frame that fore-and-aft direction extends, the backboard that the fore-and-aft direction being located at a frame front portion extends, for driving backboard lowering or hoisting gear, backboard rear end is fixedly hinged in the middle part of bed frame near the position of patient's waist and buttocks, when backboard is lifted gradually, backboard is around a rotation that is fixedly hinged, and the relative patient's waist of backboard and buttocks rearward slide, like this can to the waist of patient and buttocks applying extruding force from front to back, patient is felt under the weather, especially for the patient that some state of an illness are special, this lowering or hoisting gear may cause unpredictable danger.

Utility model content

For above problem, this utility model provides a kind of sick bed and lifting backboard thereof, makes patient have the problem of extruding sense to separate when present sick bed backboard lifts.

For achieving the above object, sick bed of the present utility model adopts following technical scheme:

Sick bed, comprise a frame, backboard and lowering or hoisting gear, it is unlike the prior art: described lowering or hoisting gear comprise be located at backboard rear end for fore-and-aft direction movement moving-member, be connected to the support of backboard and the power source for driving moving-member to move at fore-and-aft direction, described power source outfan is connected to backboard rear end or moving-member; Described support one end is articulated with between backboard front-end and back-end, and the other end is articulated with on a frame, and the pin joint of support and bed frame is in moving-member front.

Further, sick bed be provided with prolong that fore-and-aft direction extends, for leading the guide rail coordinated with moving-member.

Further, described guide rail has C type cross section, described moving-member comprise be connected to backboard rear end connector, be rotationally connected with on described connector for rolling the roller coordinated with described guide rail.

Further, described connector comprise be fixedly connected on backboard rear end bearing, with bearing be rotationally connected and the roller mount extended at fore-and-aft direction; Described roller has two and is distributed in rolling wheel support rear and front end.

Further, described bearing welds or is bolted to the rear end of backboard.

Further, it is characterized in that, described support is connecting rod.

Further, described power source is the electric pushrod that fore-and-aft direction stretches, and the front end of described electric pushrod is rotationally connected with backboard rear end or moving-member.

The usefulness of sick bed scheme of the present utility model is, when backboard lifts, its rear end travels forward, and avoids to patient's waist and buttocks applying thrust backward; When backboard lifts, support rotates around the pin joint of itself and bed frame, and the pin joint forward upward of support and backboard moves, and such backboard, when the pin joint of itself and support rotates, avoids backboard to apply extruding force from front to back to patient's waist and buttocks.

Accompanying drawing explanation

Fig. 1 is the structural representation of sick bed embodiment of the present utility model.

Detailed description of the invention

Sick bed embodiment of the present utility model:

As shown in Figure 1, sick bed comprises a frame 1, lowering or hoisting gear 2, backboard 3;

Wherein lowering or hoisting gear 2 comprises the support 211 be connected with backboard 3, the guide rail 212 extended at fore-and-aft direction be on a frame 1, lead with guide rail 212 moving-member 213, the electric pushrod 22 that coordinate, and electric pushrod 22 drives moving-member 213 to move at fore-and-aft direction as power source; Described support 211 is bar linkage structure, and its one end is hinged on the pin joint A place on a frame 1, and the other end is hinged on the pin joint B place between the front end of backboard 3 and rear end, and pin joint A is in guide rail 212 front; Guide rail 212 has the upper lower edge wing, and its cross section is C shape, and moving-member 213 moves along guide rail 212 at fore-and-aft direction;

Moving-member 213 comprises the connector 2132 being fixedly connected on backboard 3 rear end, two rollers 2131 be rotationally connected with on connector 2132; Wherein connector 2132 comprise bearing 2132b, with bearing 2132b be rotationally connected and the roller mount 2132a extended at fore-and-aft direction; Bearing 2132b lower hinge is in the middle of roller mount 2132a, and its upper weld, in backboard 3 rear end, has the crescent gap for getting out of the way roller 2131 in the middle of it; Two rollers 2131 are arranged at roller mount 2132a rear and front end respectively; Each roller 2131 is all in guide rail rolls in the lower edge wing and with guide rail and coordinates;

Electric pushrod 22 comprises the electric pushrod of fore-and-aft direction stretching motion, and the front end of electric pushrod is connected on moving-member 213, and hinged with roller mount 2132a;

Backboard 3 has flat condition and lifting status, respectively corresponding electric pushrod withdrawal and stretch out state, when electric pushrod is regained, moving-member 213 is in the rear end of guide rail 212, and when electric pushrod stretches out, moving-member 213 is in the front end of guide rail 212.

Lowering or hoisting gear operation principle of the present utility model is:

The rear end of backboard 3 moves forward under the promotion of electric pushrod 3, so just can produce the waist of patient and buttocks and dodge action, support 211 is rotated counterclockwise around pin joint A simultaneously, pin joint B forward upward moves, the instantaneous centre of rotation C forward upward movement of backboard 3, so just avoid the extruding force applying from front to back to patient's waist and buttocks.

In other specific embodiments of the present utility model, lowering or hoisting gear comprises two groups and is symmetrically set in bed frame left and right sides moving-member and a guide rail, described power source is cylinder or hydraulic cylinder, and described cylinder or hydraulic cylinder are located in the middle of a frame, and electric pushrod front end is rotationally connected with backboard rear end.

In other specific embodiments of the present utility model, guide rail is that symmetry is opened in an elongated hole extended along the longitudinal direction of frame left and right sides horizontal beam, moving-member is the bearing pin inserted in elongated hole that symmetry is welded in the left and right sides, backboard rear end, and the width of elongated hole is slightly larger than pin diameter.

In other specific embodiments of the present utility model, do not arrange guide rail, moving-member directly leads with the level frame of the bed frame left and right sides and coordinates.

In other specific embodiments of the present utility model, in moving-member, be only provided with a roller, and directly rotation is installed on bearing.

In other specific embodiments of the present utility model, bearing is bolted to backboard rear end.

In other specific embodiments of the present utility model, support is plate object, and the side of plate object is articulated with backboard, and opposite side is hinged with bed frame.

In other specific embodiments of the present utility model, support is plate object or H-shaped support or X-shaped support.
