Abstract
The invention relates to a rotation buffering and limiting mechanism which comprises a shell, a buffer spring, a transmission screw, a transmission nut and a seal cover, wherein the left end of the shell is fixedly connected with a left handrail support, the right end of the shell penetrates through a left lateral plate, a stepped hole with the diameter becoming larger from left to right is defined by the inner wall of the shell so that an inner cavity of the shell can be divided into a first section of cavity body and a second section of cavity body, the buffer spring is arranged on the outer edge of a boss in a sleeved mode, the transmission nut is arranged in the second section of cavity body, and the seal cover is connected to the right end of the shell. By means of the spiral transmission structure formed by the transmission screw and the transmission nut, the overturning motion of a handrail is converted into the linear motion of the transmission nut, and meanwhile, impact generated during overturning of the handrail is buffered through the squeezing of the transmission nut on the buffer spring. Furthermore, the overturning angle of the handrail is limited after the buffering effect is realized due to the arrangement of a step on the inner wall of the shell.

The specific embodiment
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, it is a kind of rotation buffer limit mechanism 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 symmetries 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 arrangeding 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 rotation buffer limit of the present invention mechanism 1 is fixedly connected with left armrest support 3, the other end is fixedly connected with the adapter plate 12 being 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.
Rotation buffer limit mechanism 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 of installation hanger, this passes through bolt to hanger is installed, nut is fixedly connected with left armrest support 3, its right-hand member is through the left side board 21 of handrail body 2, , left side board 21 is set in the outer rim of shell 6, the inwall of this shell 6 surrounds aperture from left to right and becomes large single order stepped hole, , the inner chamber of shell 6 is divided into first paragraph cavity 62 and the larger second segment cavity 63 of internal diameter that internal diameter is less, wherein, the cross-sectional plane of first paragraph cavity 62 is rounded, the cross-sectional plane of second segment cavity 63 is square, and these foursquare four angles are provided with chamfering, (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 chambers), and the external diameter of this boss 61 is less than the internal diameter of the first paragraph cavity 62 of shell 6 inner chambers, 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,, recoil spring 7 is between the outer rim of boss 61 and the inwall of shell 6, and this recoil spring 7 length of (state not being extruded) under free state is greater than the length of the first paragraph cavity 62 of shell 6 inner chambers;
Adapter plate 12 spline joints 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 chambers, and coordinate with drive screw 8 spirals, thereby when drive screw 8 rotation, driving nut 9 moves (thereby can push recoil spring 7) at second segment cavity 63 cathetuss of shell 6 inner chambers, and spacing by the step P on shell 6 inwalls;
