The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of height of seat governor motion, comprise hollow outer pillar 1, the lower end of outer pillar 1 is fixedly connected with the pin of seat, be connected to pillar 2 in outer pillar 1 internal sleeve, this pillar 2 can be done with outer pillar 1 and relatively rotate, be provided with ball layer 3 between the bottom of the bottom of pillar 2 and outer pillar 1, it can allow outer pillar 1 and pillar 2 power of reducing friction when relatively rotating; Be provided with interior parallel ring tooth Zhi Liguan 4 in pillar 2, be provided with a plurality of parallel ring teeth in parallel ring tooth Zhi Liguan 4 in this; Be provided with supervisor 5 in interior parallel ring tooth Zhi Liguan 4, this supervisor 5 can do relative axially-movable with interior parallel ring tooth Zhi Liguan 5, supervisor 5 is also hollow-core construction, in it, cross-under has pole 6, be provided with the concavo-convex apical ring 7 that can rotate simultaneously with pole 6 in the bottom of pole 6, the upper end of pole 6 is provided with the locking bar 8 that can allow pole 6 rotate along himself axis; Also be provided with in the bottom of pole 6 can with its pressure pipe that jointly axially moves 9, the upper end of pole 6 is provided with the descending operation bar 10 that can allow pole 6 axially move, this descending operation bar 10 is a lever in essence, and its swing fulcrum setting on the seat; On the pole 6 below pressure pipe 9, be hinged with the tooth button 11 of symmetrical structure, the tooth at this tooth button 11 two ends protrudes from outside the hole 12 that is opened on supervisor 5, and the tooth at tooth button 11 two ends can match with interior parallel ring tooth Zhi Liguan 4, and the lower shape of pressure pipe 9 and tooth button 11 match, and can allow tooth button 11 do swing.Be provided with spring 13 between the interior concavo-convex apical ring 7 of tooth button 11.

The course of work of the height of seat governor motion of the utility model embodiment is as follows: under original state, the upper end of concavo-convex apical ring 7 withstands on the lower surface of 11 two teeth of tooth button, the upper limb in the hole 12 on supervisor 5 withstands on the upper surface of 11 two teeth of tooth button, tooth button 11 can't be swung, the tooth at its two ends is stuck in the groove of interior parallel ring tooth Zhi Liguan 4, supervisor 5 vertically upward locates and by locked, the height of seat is fixed;

When needs are heightened the height of seat, pull locking bar 8, the concavo-convex apical ring 7 that locking bar 8 drives pole 6 and bottom thereof rotates, and the barbed portion of concavo-convex apical ring 7 forwards the below of 11 two teeth of tooth button to, two tooth degree of gaining freedom of tooth button 11; Upwards draw supervisor 5 this moment, tooth button 11 be retracted into supervisor 5 inside in the process of supervisor's motion of 5, when seat reached desired height, tooth button 11 snapped under the effect of spring 13 in the groove of parallel ring tooth Zhi Liguan 4 in the higher position again, and Height Adjustment is completed; Then again locking bar 8 is turned back original position, the below of tooth button 11 is carried out spacing, realize locking.

when needs reduce the height of seat, pull locking bar 8, the concavo-convex apical ring 7 that locking bar 8 drives pole 6 and bottom thereof rotates, and the barbed portion of concavo-convex apical ring 7 forwards the below of 11 two teeth of tooth button to, two tooth degree of gaining freedom of tooth button 11, then upwards lift the outer end of descending operation bar 10, the pressure pipe 9 that the other end of descending operation bar 10 can drive pole 6 and its underpart moves downward simultaneously, in the process that pressure pipe 9 moves downward, two teeth directionals of tooth button 11 can be pressed down, allow its two ends be retracted into supervisor 5 inside, supervisor's 5 degree of gaining freedom, simultaneously to pressing down supervisor 5, allow supervisor 5 and seat move downward simultaneously, when reaching desired height, press down the outer end of descending operation bar 10, pressure pipe 9 is no longer exerted pressure to tooth button 11, two teeth of tooth button 11 are flat stretching under the effect of spring 13, again protrude from outside supervisor 5 hole 12, and be stuck in the groove of interior parallel ring tooth Zhi Liguan 4, then again locking bar 8 is turned back original position, below to tooth button 11 is carried out spacing, realize locking.
