Summary of the invention
Therefore, the object of the present invention is to provide a kind of locking and relieving mechanism of regulating before and after the executive chair seat support reliable, simple in structure that lock and discharge.
The objective of the invention is to realize like this:
Locking and the relieving mechanism regulated before and after a kind of executive chair seat support comprise box body, alignment pin and dead bolt, and the outer wall of alignment pin is provided with positioning sleeve; Positioning sleeve is fixedly connected with alignment pin, is provided with vertical back-moving spring between positioning sleeve and the box body bottom, and alignment pin stands in the box body through vertical back-moving spring; Positioning sleeve slides up and down along inboard wall of cartridge, and dead bolt is installed in the box body rotationally, and is positioned at the alignment pin side; The box body of alignment pin side is provided with opening, and transmission cooperates between dead bolt pressed end and the positioning sleeve, and the dead bolt other end passes opening and stretches out the link of box body for being connected with the executive chair regulating handle; Be provided with between dead bolt end and the box body of link and be provided with horizontal back-moving spring; When seat support was in the lock state, vertical back-moving spring was in extended configuration with horizontal back-moving spring, and alignment pin moves up and insert in the slide plate on the top.When seat support need move forward and backward, rotate the executive chair handle, handle drives the dead bolt link and rotates; The pressed end pressed downward positioning sleeve of dead bolt, positioning sleeve drives alignment pin and moves down, and alignment pin discharges slide plate; Vertical back-moving spring is in compressive state with horizontal back-moving spring; After handle was released, alignment pin resetted through two back-moving springs, locks slide plate again.
Technique scheme also can be done following further perfect:
Said vertical back-moving spring upper end is connected with positioning sleeve; Vertical back-moving spring bottom is resisted against box bottom; Said box bottom is provided with a through hole; Vertical back-moving spring and through hole are passed in the alignment pin bottom, and alignment pin bottom cross-sectional area and through hole cross-sectional area sizableness can guarantee further that through the spacing of through hole alignment pin keeps vertical and moves.
[0008] amplitude of fluctuation of the horizontal width of said opening and dead bolt link is suitable, meets the displacement of alignment pin through the amplitude of fluctuation of the spacing assurance dead bolt of opening side walls.
Said horizontal back-moving spring one end is connected with box side wall, and laterally the back-moving spring other end is connected with dead bolt, can move up fast with the realization alignment pin through vertical and horizontal resetting means.
Architecture simplicity of design of the present invention is reasonable, and dead bolt rotates reliable, and alignment pin moves up and down smooth and easy, because this is simple in structure and reliable, has guaranteed the service life of executive chair.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is made further detailed description.
In conjunction with accompanying drawing, locking and the relieving mechanism regulated before and after a kind of executive chair seat support comprise box body 1, alignment pin 2 and dead bolt 3, and this mechanism is installed on base plate 4 belows through box body 1, and base plate 4 tops are provided with slide plate 5, and the seat support (not shown) is installed on the slide plate 5.Realize that through moving forward and backward of slide plate 5 seat support moves forward and backward.
The outer wall of alignment pin 2 is provided with positioning sleeve 20; Positioning sleeve 20 is fixedly connected through lateral pin 21 with alignment pin 2; Be provided with vertical back-moving spring 22 between positioning sleeve 20 and box body 1 bottom, vertical back-moving spring 22 upper ends are connected with positioning sleeve 20, and vertical back-moving spring 22 bottoms are resisted against box body 1 bottom surface 10; Box body 1 bottom surface 10 is provided with through hole 11; Alignment pin 2 bottom cross-sectional areas and through hole 11 cross-sectional area sizableness, alignment pin 2 bottoms are passed down through vertical back-moving spring 22 and through hole 11, and alignment pin 2 stands in the box body 1 through vertical back-moving spring 22.
