SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a simple structure just can alleviate the tired flexible cushion of knee and shank is provided.

The utility model discloses a realize through following technical scheme:

the utility model provides a flexible cushion, its includes main cushion and vice cushion, main cushion includes bottom plate, middle elastic layer and outer parcel layer, middle elastic layer fixed mounting is in the bottom plate upper surface, and the rope drawing is installed to outer parcel layer suit in middle elastic layer upper surface, middle elastic layer side and bottom plate side and bottom, and fixed mounting has two slide rails on the bottom plate bottom surface, vice cushion passes through the slider and installs on the slide rail, and folding flexible landing leg is equipped with to anterior hinge on the bottom surface of vice cushion, and middle part fixed mounting has folding flexible landing leg cardboard on the vice cushion bottom surface.

Furthermore, the foldable telescopic supporting leg comprises an upper screw rod, a lower screw rod and an adjusting sleeve, the top of the upper screw rod is hinged to the bottom surface of the auxiliary cushion, the upper screw rod and the lower screw rod are respectively provided with external threads with opposite rotation directions, the adjusting sleeve is sleeved between the upper screw rod and the lower screw rod, and two ends of the adjusting sleeve are provided with internal threads matched with the external threads of the upper screw rod and the lower screw rod.

Furthermore, the lower end part of the lower screw rod is sleeved with an anti-skid pad.

Furthermore, the middle elastic layer is high-density sponge, and the inner surface of the outer wrapping layer is stuck with far infrared electric heating cloth.

The beneficial effects of the utility model

The utility model provides a pair of flexible cushion sets up a vice cushion that can stretch out and draw back below main cushion, when the staff sits long-term work shank and knee in the front of the computer and feels tired or stiff, can drag out vice cushion along the slide rail forward, then open folding flexible landing leg to vertical state, make folding flexible landing leg lower extreme fall subaerially, form stable support to vice cushion, the staff sits on main cushion like this, can lift the both legs and put on vice cushion, thereby guarantee the blood circulation of shank and alleviate knee and shank fatigue. When the folding telescopic supporting leg clamping plate is not used, the folding telescopic supporting leg can be folded and clamped on the folding telescopic supporting leg clamping plate after being folded, and then the auxiliary seat cushion is pushed back to the position below the main seat cushion along the sliding rail. The structure is simpler and the adjustment is convenient and labor-saving.

Drawings

Fig. 1 is a schematic structural view of the folding telescopic leg in an unfolded state;

fig. 2 is a schematic view of the folding telescopic leg of the present invention in a folded state;

in the figure, 1, an outer wrapping layer, 2, far infrared electric heating cloth, 3, an intermediate elastic layer, 4, a bottom plate, 5, a sliding rail, 6, an anti-skid pad, 7, a lower screw rod, 8, an adjusting sleeve, 9, an upper screw rod, 10, an auxiliary cushion, 11, a drawstring, 12, a folding telescopic supporting leg clamping plate and 13, a sliding block are arranged.

Detailed Description

The utility model provides a flexible cushion, its includes main cushion and vice cushion, main cushion includes bottom plate 4, middle elastic layer 3 and outer parcel layer 1, middle elastic layer fixed mounting is in the bottom plate upper surface, and the rope drawing 11 is installed to outer parcel layer suit in middle elastic layer upper surface, middle elastic layer side and bottom plate side and bottom, conveniently changes and washs outer parcel layer.

Two sliding rails 5 are fixedly mounted on the bottom surface of the bottom plate, the auxiliary cushion 10 is mounted on the sliding rails through sliding blocks 13, folding telescopic supporting legs are hinged to the front portion of the bottom surface of the auxiliary cushion, and a folding telescopic supporting leg clamping plate 12 is fixedly mounted in the middle of the bottom surface of the auxiliary cushion.

Further, folding flexible landing leg includes upper portion screw rod 9, lower part screw rod 7 and adjusting collar 8, upper portion screw rod top is articulated with vice cushion bottom surface and upper portion screw rod and lower part screw rod are equipped with the opposite external screw thread of turning to respectively, adjusting collar suit is between upper portion screw rod and lower part screw rod, and the both ends of adjusting collar are equipped with the internal thread with the external screw thread matched with of upper portion screw rod and lower part screw rod, when vice cushion needs pull out, twist and move the adjusting collar and just can make upper portion screw rod and lower part screw rod alternate segregation or be close to, thereby adjust the height of folding flexible landing leg as required, even uneven ground or the elevation is different also can be adjusted well, makes vice cushion be in the horizontality, and forms the outrigger to vice cushion, adjusts very convenient laborsaving.

Furthermore, the lower end part of the lower screw rod is sleeved with an anti-slip pad 6, so that the folding telescopic supporting leg is prevented from sliding randomly and the ground is prevented from being scratched.

Furthermore, the middle elastic layer is made of high-density sponge, the inner surface of the outer wrapping layer is pasted with the far infrared electric heating cloth 2, a user feels more comfortable, and after the far infrared electric heating cloth is heated, blood circulation can be promoted, and hip fatigue caused by long-term sitting on the cushion is relieved.

The utility model provides a pair of flexible cushion, owing to set up a vice cushion that can stretch out and draw back below main cushion, when the staff sits long-term work shank and knee in the front of the computer and feels tired or stiff, can drag out vice cushion along the slide rail forward, then open folding flexible landing leg to vertical state, make folding flexible landing leg lower extreme fall subaerially, form stable support to vice cushion, the staff sits on main cushion like this, can lift the both legs and put on vice cushion, thereby guarantee the blood circulation of shank and alleviate knee and shank fatigue. When the folding telescopic supporting leg clamping plate is not used, the folding telescopic supporting leg can be folded and clamped on the folding telescopic supporting leg clamping plate after being folded, and then the auxiliary seat cushion is pushed back to the position below the main seat cushion along the sliding rail. The structure is simpler and the adjustment is convenient and labor-saving.

To sum up, the utility model provides a pair of flexible cushion, simple structure just can alleviate knee and shank fatigue.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
