The specific embodiment
Below in conjunction with accompanying drawing and implementation the utility model is explained.
Structure is adjusted in the rotation of armrest of the present utility model, extremely shown in Figure 7 such as Fig. 1, include handrail 1, armrest support 2 and be located at handrail 1 and the guiding mechanism of 2 of armrest supports, this guiding mechanism is by pedestal 3, fixed disk 4 and lock pin 5 form, wherein, pedestal 3 is located on the handrail 1, be fixedly mounted on the bottom of handrail 1, fixed disk 4 is installed on the armrest support 2, be fixed on armrest support 2 faying face relative with handrail 21,4 of pedestal 3 and fixed disks form and articulate, and make pedestal 3 rotate relative to fixed disk 4, to adjust the position on the handrail circumferencial direction, lock pin 5 is located on the fixed disk 4 and with pedestal 3 formation and is cooperated;
The middle part of described pedestal 3 is provided with connecting hole 31, and take this connecting hole 31 as the center of circle, is interval with some locating holes 32 at same circumferencial direction;
The middle part of described fixed disk 4 is provided with pivot hole 41, one pivot 6 passes the pivot hole 41 of connecting hole 31 and the fixed disk 4 of pedestal 3, pedestal 3 and fixed disk 4 are articulated, the side of fixed disk 4 in pivot hole 41 provides a through hole 42 again, this through hole 42 is provided with internal thread, pedestal 3 take pivot as the axle center when fixed disk 4 rotates, this through hole 42 is selected locating hole 32 one and pedestal and is communicated;
Described lock pin 5 is by sleeve 51, alignment pin 52, spring 53 and draw ring 54 form, sleeve 51 is hollow structure, the top is provided with thread segment 511, utilizing thread segment 511 to cooperate with fixed disk through hole 42 is screwed in sleeve 51 on the fixed disk 4, the bottom of this sleeve 51 is provided with short slot 512, and with the stagger shallow slot 513 of certain position of this short slot 512, described alignment pin 52 is set on the hollow bulb of sleeve 51 in conjunction with spring 53, but outside the interior receipts of the front end elasticity of this alignment pin 52 or the protrusion sleeve 51, the rear end of alignment pin 52 connects draw ring 54, convex with the convex tendon 541 with short slot 512 corresponding matching of sleeve 51 on the draw ring 54, spring 53 is set on the alignment pin 52, and the two ends of spring 53 act on respectively alignment pin 52 and sleeve 51.
Operation principle of the present utility model is: under the original state, the convex tendon 541 of draw ring 54 is over against the short slot 512 of sleeve 51, form corresponding concavo-convex cooperation with short slot 512, this moment, the front end of alignment pin 52 protruded outside the sleeve 51, the through hole 42 that sees through fixed disk 4 stretches in the locating hole 32 of pedestal 3, pedestal 3 and fixed disk 4 are locked together, and at this moment handrail 1 maintains static; During adjusting, be pulled outwardly to move with the hand ring 54 and rotate and fall into after an angle makes convex tendon 541 and the short slot 512 of sleeve 51 separates in the shallow slot 513 on one side, alignment pin 52 is along with draw ring 54 actions and Compress Spring 53 are in the power state that holds simultaneously, in the through hole 42 of alignment pin front end disengaging fixed disk and the locating hole 32 retraction sleeves 51 of pedestal, releasing is to the locking of pedestal 3 and fixed disk 4, at this moment rotary handle makes pedestal 3 rotate relative to fixed disk 4 as the axle center take pivot, after being adjusted to desired location, again spurring draw ring 54 and rotation makes the convex tendon 541 of draw ring aim at short slot 512 positions, after loosening draw ring, draw ring convex tendon 541 falls in the short slot 512 of sleeve under the effect of spring 53, alignment pin 52 is along with draw ring 54 its front ends of action protrude outside the sleeve 51 simultaneously, the through hole 42 that sees through fixed disk 4 stretches in the locating hole 32 of pedestal relevant position, pedestal 3 and fixed disk 4 are locked together, handrail 1 is fixed on the position after the adjustment.
