The specific embodiment
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be elaborated.
As shown in Figure 1, Figure 2, Figure 3 shows, for an embodiment of seat rotary positioning structure provided by the present invention, seat rotary positioning structure provided by the present invention has one group and is located at and in seat, controls the restricted group body 6 that pedestal is rotated or locates, restricted group body 6 comprises: a sleeve 2, be combined in top one end of the air pressure rod 1 of seat middle part, form one section of space 21 at the inner side of sleeve 2 periphery, in space 21, be inserted in one and form the ring 3 of multiple depressions 31 at outer layer surface, and packing is inserted a top cover 4 ring 3 is applied to orientation restriction in the upper end open of sleeve 2.
As Fig. 1, shown in Fig. 4, extend one section of inner position in a side of sleeve 2 and run through the pipeline section 22 that is provided with a hole 221, pipeline section 22 outwardly a side can coordinate the bar section 51 of being inserted in an end and being combined with spring 52, cut in one end outwardly of bar section 51 hole 531 that a side cover 53 forms therebetween, and stretch out outside side cover 53, the paragraph outwardly of bar section 51 can be held in the mouth between the lug up and down 541 of pulling piece 54 corresponding one end, and by a positioning rod 55, bar section 51 these ends and pulling piece 54 are done to orientation pivot joint, be located in pulling piece 54 act on spacing between the lug 541 of a side upper and lower backstay 55 and the medial extremity 542 of pulling piece 54 and and the adjacent side 543 of pulling piece 54 between spacing be set as different length (as Fig. 6, shown in Fig. 7), in addition, one end that group is located at the side cover 53 in restricted group body 6 is provided with a hole 532, 23 pairs of side covers of pin 53 in order to pipeline section 22 predeterminated positions that are applied in sleeve 2 one sides carry out orientation restriction.
As shown in Figure 2, the restricted group body 6 that utilizes group to be located at the air pressure rod 1 top one end in seat makes pedestal temporarily be set as the operation that does not rotate location, with hand, pulling piece 54 to be dialled and cut (as shown in Figure 7) to a side, utilize on pulling piece 54 spacing between backstay 55 and adjacent side 543 shorter, can order about that bar section 51 is interior passes and make among the corresponding depression 31 of inner one end incision ring 3, so that the orientation of pedestal is restricted to positioning states.
Make seat reply the operation for rotatable state, as shown in Figure 5, Figure 6, that the pulling piece of state shown in Fig. 7 54 is done oppositely and dials and cut, the setting of growing by the spacing between backstay 55 on pulling piece 54 and medial extremity 542, order about bar section 51 and outwards exit the corresponding depression 31 of ring 3, make pedestal can carry out once again required orientation rotation.
As shown in Fig. 8, Fig. 9, Figure 10, the second embodiment of the seat rotary positioning structure designing for the present invention, group is located to be controlled the restricted group body 8 that pedestal is rotated or locates and comprises in seat: a sleeve 2, be combined in top one end of the air pressure rod 1 of seat middle part, form one section of space 21 at the inner side of sleeve 2 periphery, in space 21, be inserted in the ring 3 that an outer aspect forms multiple tracks depression 31, and packing is inserted a top cover 4 ring 4 is applied to orientation restriction in the upper end open of sleeve 2.
As Fig. 8, shown in Figure 11, extend one section of inner position in a side of sleeve 2 and run through the pipeline section 22 that is provided with a hole 221, be inserted in the pipeline section 22 bar section 71 that a side can coordinate a front end to be combined with spring 72 outwardly, the rear one end of leaning on of bar section 71 is formed with the revolving part 73 of several continuous recess 731 against a periphery, the bar section 732 that revolving part 73 other ends extend runs through into a hollow sliding part 74, and the corresponding protuberance 741 that makes sliding part 74 act on one end formation can be cut between the recess 731 of revolving part 73, and revolving part 73 and sliding part 74 are provided with at least one or more than one groove 733 at the periphery of default paragraph, 742(as shown in Figure 8), make bearing directing to coordinate sleeve 2 this section of inner corresponding flanks 222 that form of pipeline section 22, can overlap unification 75Bing Shi one end, press section at the outer opening of pipeline section 22 of sleeve 2 and be covered in sliding part 74 outsides (as shown in figure 11).
As shown in Figure 9, the restricted group body 8 that utilizes group to be located at the air pressure rod 1 top one end in seat makes pedestal temporarily be set as the operation that does not rotate location, with hand, press section 75 to be pressed down to (as shown in Figure 13, Figure 14), order about sliding part 74 pass revolving part 73 along the flank 222 of pipeline section 22 by inside adjacent bar section 71 pushing tow, with the corresponding depression 31 of incision ring 3, revolving part 73 can be subject to the orientation of the interior corresponding flank 222 of pipeline section 22 and keep out (as shown in figure 15), is positioning states with the orientation rotation that limits pedestal.
And to make seat reply the operation that can make rotation status, as shown in Figure 10, Figure 11, that the press section shown in Figure 14 75 is pressed down once again, pass the interior introducing of revolving part 73 to order about sliding part 74, bar section 71 and revolving part 73, sliding part 74 are pushed back (as shown in Figure 11, Figure 12) by the restoring force that utilizes the spring 72 in adjacent one end bar section 71, and making bar section 71 exit the corresponding depression 31 of ring 3, pedestal just can carry out required orientation rotation once again.
