Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

Embodiment 1, as shown in fig. 1, the utility model discloses an adjustable triangle seat is lifted to components of a whole that can function independently rotation type, including main seat 2 and the adjust knob 8 that has the lead screw, the bottom of main seat 2 is fixed with base 1, hinge 9 is passed through respectively to main seat 2's both sides articulates left vice seat 3 and right vice seat 4, base 1's front end both sides set up the rotatable push rod 5 that lifts of components of a whole that can function independently, the push rod 5 that lifts of both sides cuts the formula through connecting piece 6 and connects, 5 outer ends of the push rod that lifts of the left and right sides respectively with left vice seat 3 and the 4 flexonics of right vice seat, adjust knob 8 top lead screws pass on connecting piece 6 draw pearl 10 through-hole threaded connection to base 1.

The outer end of the lifting push rod 5 is tilted upwards and is fixed with a ball head 7, and a reserved threaded hole 11 matched with a screw rod of an adjusting knob 8 is formed in the base 1.

The adjusting knob 8 is vertically arranged, the lifting push rod 5 is hinged to two sides of the front end of the base 1 and can rotate around a hinged point in a vertical plane, and sliding rails 12 matched with the ball head 7 are arranged at the bottoms of the left auxiliary chair surface 3 and the right auxiliary chair surface 4.

The hinge 9 may be a spring-damped hinge 9.

The adjusting knob 8 can be replaced by an electric push rod or a controllable gas spring.

The main chair surface 2, the left auxiliary chair surface 3 and the right auxiliary chair surface 4 adopt soft plastics on one surface of the whole body to replace or are coated by soft materials such as sponge and the like.

The slide rail 12 is arc-shaped, and the bottom of the slide rail 12 is provided with an arc-shaped slide groove for accommodating the ball head 7 and allowing the ball head 7 to slide therein.

The lead screw at the top of the adjusting knob 8 passes through the connecting piece 7 to rotate the connected pull ball 11 through hole and be connected to the reserved threaded hole 11 at the front part of the base 1, the rotation of the adjusting knob 8 drives the turnover change of the position of the lifting push rod 5, and then the left auxiliary chair surface 3 and the right auxiliary chair surface 4 which are lifted are driven to turn over, and the change of the angle and the position is realized.

The working principle is as follows: when the adjusting knob 8 is rotated, the lifting pull rod 5 is driven to turn over and move in a vertical plane around a hinged point, and the left auxiliary chair surface 3 and the right auxiliary chair surface 4 are lifted to be synchronously turned over up and down through the traction of the ball head 7 and the matching of the sliding rail 12, so that the chair surface structure is deformed.

Embodiment 2, as shown in fig. 2, is different from embodiment 1 in that the adjusting knob 8 is horizontally disposed, the lifting push rod 5 is hinged to two sides of the front end of the base 1 and can rotate around a hinge point in a horizontal plane, and the bottoms of the left auxiliary seat 3 and the right auxiliary seat 4 are both provided with a ball 7 for contacting.

The theory of operation, when rotatory adjust knob 8, adjust knob 8's rotation will drive and lift push rod 5 front and back position change, lift push rod 5 and turn over in vertical plane around the pin joint and move, when lifting push rod 5 transversely released and being the wide-angle and separating, bulb 7 lifts left vice seat 3 and right vice seat 4 and is in the parallel state, when lifting push rod 5 by transversely pull back and, bulb 7 is no longer lifting left vice seat 3 and right vice seat, thereby make left vice seat 3 and right vice seat 4 overturn under the action of gravity, be the contained angle state with main seat 2, as shown in fig. 3.

To sum up, the utility model discloses a structure is lifted to components of a whole that can function independently rotation type, the modern design, it is simple reliable, stability is strong, and space utilization is high, can realize the different gesture adjustment of seat structure to adapt to different users 'individual character sign, through adjusting user's height and angle, reduce buttock pressure, delay fatigue, improved the travelling comfort and the pleasing to the eye degree of seat, convenient popularization.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.

In the description of the present invention, the terms "inside", "outside", "longitudinal", "lateral", "up", "down", "top", "bottom", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description of the present invention rather than requiring the present invention to be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
