Detailed description of the invention
Below in conjunction with accompanying drawing, provide preferred embodiment of the present invention, and be described in detail.
Refer to Fig. 3-10, the present invention, i.e. a kind of slew buffer stop gear 1, it is arranged on seat handrail, this handrail comprises: handrail body 2, left armrest support 3, right armrest support 4 and base 5, wherein, left armrest support 3 and right armrest support 4 symmetry are fixedly connected on base 5, handrail body 2 is connected between left armrest support 3 and right armrest support 4 turningly, specifically, handrail body 2 comprises the left side be arranged in parallel, right side board 21, 22 and be connected to a left side, right side board 21, flat board 23 between 22, wherein, the right side board 22 of handrail body 2 is connected with right armrest support 4 by S. A. 11, one end of slew buffer stop gear 1 of the present invention is fixedly connected with left armrest support 3, the other end is fixedly connected with the adapter plate 12 be fixedly connected on dull and stereotyped 23 through the left side board 21 of handrail body 2, wherein, adapter plate 12 be arranged in parallel with the left side board 21 of handrail body 2.
Slew buffer stop gear 1 specifically comprises: shell 6, recoil spring 7, drive screw 8, driving nut 9 and capping 10, wherein:
The left end outer rim of shell 6 is provided with a pair installation hanger, this passes through bolt to installation hanger, nut is fixedly connected with left armrest support 3, its right-hand member is through the left side board 21 of handrail body 2, namely, left side board 21 is set in the outer rim of shell 6, the inwall of this shell 6 surrounds the single order stepped hole that aperture from left to right becomes large, namely, the first paragraph cavity 62 that the inner chamber of shell 6 is divided into internal diameter less and the larger second segment cavity 63 of internal diameter, wherein, the circular in cross-section of first paragraph cavity 62, the cross-sectional plane of second segment cavity 63 is in square, and these foursquare four angles are provided with chamfering, (namely left side near left armrest support 3 in the inner chamber of this shell 6 is provided with boss 61, boss 61 is arranged in the first paragraph cavity 62 of shell 6 inner chamber), and the external diameter of this boss 61 is less than the internal diameter of the first paragraph cavity 62 of shell 6 inner chamber, the right side of this boss 61 is provided with a pit 64, and the internal diameter of this pit 64 is less than the external diameter of boss 61,
Recoil spring 7 is set in the outer rim of boss 61, namely, recoil spring 7 is between the outer rim and the inwall of shell 6 of boss 61, and the length of this recoil spring 7 (state be not namely extruded) is in a free state greater than the length of the first paragraph cavity 62 of shell 6 inner chamber;
Adapter plate 12 spline joint in the right-hand member of drive screw 8 and handrail body 2, its left end stretches into the inner chamber of shell 6, and inserts in pit 64;
Driving nut 9 is arranged in the second segment cavity 63 of shell 6 inner chamber, and with drive screw 8 threaded engagement, thus when drive screw 8 rotates, driving nut 9 is at second segment cavity 63 linear movement (thus can extrude recoil spring 7) of shell 6 inner chamber, and spacing by the step P on shell 6 inwall;
The right-hand member that capping 10 is connected to shell 6 drops out shell 6 to prevent driving nut 9, and the surface of this capping 10 is provided with the through hole passed for drive screw 8.
Principle of work of the present invention is as follows:
When launching handrail, handrail body 2 overturns, the drive screw 8 be fixedly connected with it is driven to rotate, thus be the straight-line motion of driving nut 9 by the convert rotational motion of handrail body 2, driving nut 9 is moved from right to left in the second segment cavity 63 of shell 6 inner chamber, the straight-line motion of driving nut 9 causes recoil spring 7 to be compressed, and then the resistance that recoil spring 7 is produced plays the effect of buffering handrail body 2 rotation; When driving nut 9 moves to end of run, contact with the step P on shell 6 inwall, this step P prevents the continuation campaign of driving nut 9, make drive screw 8 to rotate simultaneously, thus cause the handrail body 2 be connected with drive screw 8 to rotate, namely serve the position-limiting action that handrail body 2 is overturn thus.
When handrail is returned to rounding state, the reverse upset of handrail body 2, the drive screw 8 be fixedly connected with it is driven to rotate, thus driving nut 9 is moved from left to right in the second segment cavity 63 of shell 6 inner chamber, buffer release spring 7, makes it to return back to free state, and driving nut 9 moves to and contacts i.e. stop motion with capping 10, now, handrail resets.
It should be noted, the present invention with said structure also goes for other rotating mechanism.
Above-described, be only preferred embodiment of the present invention, and be not used to limit scope of the present invention, the above embodiment of the present invention can also make a variety of changes.Namely every claims according to the present patent application and description are done simple, equivalence change and modify, and all fall into the claims of patent of the present invention.The not detailed description of the present invention be routine techniques content.
