Technical solution of the present invention is achieved in that a kind of armrest system, comprises handrail tubing string assembly, handrail rotating shaft and arm assembly; One end of described handrail rotating shaft is captiveed joint with arm assembly by socket head cap screw, and the other end can be rotatably set in the handrail tubing string assembly; Described handrail rotating shaft bottom is provided with the handrail spring, and top is provided with keyway; The bottom of described arm assembly is provided with the handrail limiting stopper, and described handrail limiting stopper is captiveed joint with the handrail rotating shaft by the handrail card key that is provided with in the described keyway; The head of described handrail tubing string assembly is provided with the handrail fixture block, and described handrail fixture block and handrail limiting stopper have played spacing effect jointly.
Preferably, upper surface one side of described handrail fixture block is provided with projection, and opposite side has circle hole groove; The thickness of described projection equals the thickness of handrail limiting stopper; Described handrail limiting stopper is provided with handrail card bead and the second holding screw in the position of circle hole groove.
Preferably, described handrail fixture block is arranged on the head of handrail tubing string assembly regularly by four the first holding screws.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described armrest system of the present invention program, because an end of described handrail rotating shaft is captiveed joint with arm assembly by socket head cap screw, the other end can be rotatably set in the handrail tubing string assembly; Described handrail rotating shaft bottom is provided with the handrail spring, and top is provided with keyway; The bottom of described arm assembly is provided with the handrail limiting stopper, and described handrail limiting stopper is captiveed joint with the handrail rotating shaft by the handrail card key that is provided with in the described keyway; The head of described handrail tubing string assembly is provided with the handrail fixture block, and described handrail fixture block and handrail limiting stopper have played spacing effect jointly.Armrest system of the present invention, it is not only simple in structure, and productive costs is low, and easy to operate, and applicability is strong.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the block diagram of armrest system of the present invention;
Accompanying drawing 2 is the cutaway view of armrest system of the present invention;
Accompanying drawing 3 is the cutaway view at another visual angle of armrest system of the present invention;
Accompanying drawing 4 is the partial enlarged drawing of accompanying drawing 3;
Wherein: 1, handrail tubing string assembly; 2, handrail rotating shaft; 3, arm assembly; 4, socket head cap screw; 5, handrail spring; 6, keyway; 7, handrail limiting stopper; 8, handrail card key; 9, handrail fixture block; 10, projection; 11, circle hole groove; 12, handrail card bead; 13, the second holding screw; 14, the first holding screw.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Such as the described a kind of armrest system of the present invention of accompanying drawing 1-4, comprise handrail tubing string assembly 1, handrail rotating shaft 2 and arm assembly 3; One end of described handrail rotating shaft 2 is captiveed joint with arm assembly 3 by socket head cap screw 4, and the other end can be rotatably set in the handrail tubing string assembly 1; Described handrail rotating shaft 2 bottoms are provided with handrail spring 5, and top is provided with keyway 6; The bottom of described arm assembly 3 is provided with handrail limiting stopper 7, and described handrail limiting stopper 7 is captiveed joint with handrail rotating shaft 2 by the handrail card key 8 that is provided with in the described keyway 6; The head of described handrail tubing string assembly 1 is provided with handrail fixture block 9, and described handrail fixture block 9 has played spacing effect jointly with handrail limiting stopper 7.
Upper surface one side of described handrail fixture block 9 is provided with projection 10, and opposite side has circle hole groove 11; The thickness of described projection 10 equals the thickness of handrail limiting stopper 7; Described handrail limiting stopper 7 is provided with handrail card bead 12 and the second holding screw 13 in the position of circle hole groove 11.Described handrail fixture block 9 is arranged on the head of handrail tubing string assembly 1 regularly by four the first holding screws 14.
Armrest system of the present invention, in opening the process of handrail, at first upwards spur arm assembly 3 by operating personal, because arm assembly 3, handrail rotating shaft 2 and handrail limiting stopper 7 link into an integrated entity, the handrail spring 5 that handrail rotating shaft 2 bottoms are provided with is simultaneously compressed; Then the rotary handle assembly 3, arm assembly 3, handrail rotating shaft 2 and handrail limiting stopper 7 integral body are around 1 rotation of handrail tubing string assembly, handrail limiting stopper 7 contacts with the projection 10 that handrail fixture block 9 is provided with when rotation 90 is spent, handrail card bead 12 is arranged in circle hole groove 11 just at this moment, has played bidirectionally limited effect.In closing the process of handrail, the same arm assembly 3 that upwards spurs, reciprocal rotary handle assembly 3 is lived by the projection 10 on the handrail fixture block 9 is spacing when spending when rotating 90.In the process of using rotary handle assembly 3, handrail spring 5 has played the effect of restriction arm assembly 3 axial motions.
Armrest system of the present invention, it is not only simple in structure, and productive costs is low, and easy to operate, and applicability is strong.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
