Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, and provides detailed description of the invention.
As Figure 1-5, the utility model seat rotating handrail, this rotating handrail rotates before and after can realize, have 5 gears can regulate, be respectively I gear, II gear, III gear, IV gear, V gear, each gear angle of inclination is different, when handrail is in I gear, handrail height can be made to reduce a lot, under seat can being pushed into desk, effectively save working space.This rotating handrail comprises handrail 1, armrest base 2, slide block 3, Compress Spring 4, trim 17, wherein, handrail 1 comprises the handrail panel 7 connected successively from top to bottom, bar 8, hollow circular handrail connector 9, trim 17 is equipped with the side at handrail connector 9, pad 18 is also equipped with between trim 17 and handrail connector 9, be connected by screw between pad 18 with boss 6, one end that armrest base 2 is connected with handrail 1 is fixedly installed joint pin 5, the cylinder table 6 of hollow structure is fixedly installed in the middle part of slide block 3, slide block 3 and armrest base 2 are rotatably assorted by joint pin 5 and cylinder table 6 clamping, Compress Spring 4 socket is arranged on the outer wall of cylinder table 6, handrail 1 coordinates with armrest base 2 and is rotationally connected.The inwall of handrail connector 9 is symmetrically arranged with inwardly outstanding projection 10, this projection 10 inside is provided with groove 19, the outer circle wall of slide block 3 is provided with projection 10 with the use of groove 11, groove 11 is provided with inclined-plane 12.
Armrest base 2 and slide block 3 are respectively arranged with the rotating mechanism rotated for controlling slide block 3, this rotating mechanism comprises boss 13, tooth A14, arcuate socket 15, tooth B16, boss 13 clamping is arranged in arcuate socket 15, tooth A14 engages each other with tooth B16 or is separated, tooth A and tooth B is provided with hypotenuse and straight flange, handrail single direction rotation is convenient in this setting, and boss 13 and tooth A14 are all symmetricly set on the both sides of joint pin 5, and boss 13 and tooth A14 are arranged in a crossed manner; Arcuate socket 15 is symmetricly set on the post jamb of cylinder table 6, the one-body molded edge being arranged on slide block 3 of tooth B16.
The utility model operating instruction, five gears that handrail 1 is arranged, wherein, II gear, III gear, IV gear is normal gear, I gear and V gear are back to zero gear, the anglec of rotation between I gear and II keeps off is 35 degree, II gear and III keep off between and III keep off and IV keep off between angle of inclination be 15 degree, angle of inclination between IV gear and V keeps off is 35 degree, handrail 1 is in II gear, III gear, during IV gear, counterclockwise can direct regulation stall, can not directly regulate clockwise, just required gear must can be transferred to after V gear and I gear back to zero, such as, suppose that original speed position is III gear, if need gear to be transferred to IV gear, then handrail is turned 15 degree counterclockwise, if need gear to be transferred to II gear from III gear, then first forward handrail to V gear, finally forward II gear to by I gear again.
Utility model works principle and process, when handrail 1 keeps off at gear II, III gear, IV keeps off, the effect of slide block 3 spring 4 by compression, the tooth B16 on the slide block 3 and tooth A14 on armrest base 2 is made to be in engagement, shape due to tooth is on one side straight flange, hypotenuse, can only one-directional rotation when two teeth engage, now, handrail counterclockwise one-directional rotation only; When handrail turn to gear V keep off time, the boss 13 on armrest base 2 slides into end in the arcuate socket 15 of slide block 3, and when handrail 1 continues to turn counterclockwise, slide block 3 and handrail 1 relatively rotate; Handrail keeps off continuation by gear V and rotates 0-12 degree backward, slide block 3 and handrail 1 relatively rotate, in relative rotational motion, projection 10 on handrail 1 slides along the inclined-plane 12 of the groove 11 on slide block 3, slide block 3 is to the inner indentation of groove 19, now slide block 3 is stuck in groove 19 li and can not throws off, and the tooth A14 on tooth B16 and armrest base throws off, and now handrail can freely rotate counterclockwise; Gear handrail is when free rotary state keeps off to gear I, its principle with attached turn to when gear V keeps off identical, boss 13 on armrest base has slided into another end of slide block arcuate socket 15, and when handrail 1 continues to rotate forward, slide block 3 and handrail 1 relatively rotate; Handrail 1 keeps off continuation by gear I and rotates forward 0-12 degree, slide block 3 and handrail 1 relatively rotate, in relative rotational motion, the groove 19 of projection 10 inside on handrail 1 slides along the inclined-plane 12 of the groove 11 on slide block 3, the effect of spring 4 by compression, automatically outwardly, tooth B16's slide block 3 is meshed with the tooth A14 on armrest base, now handrail 1 can turn to that gear II keeps off, III gear, IV gear backward, so forms a circulation.This rotating handrail, structural design is simple, convenient to operation.
