Frame surface is relied on, is hooked position equipped with elastic component, elastic component one end is fixedly connected with frame, and the elastic component other end suppresses
Positioning column surface, seat frame front end opposing frame is hanging, and frame seat is located on fixed frame.
Release and locking device are equipped in the frame body, operation release and the spanner of locking device are rotatably mounted at seat
It pads on frame, frame may be implemented in rotating spanner and seat frame locks, and seat frame front end may be implemented with respect to frame in rotating spanner again
Frame tilts down.
The above technical solution can be further improved as follows.
The release and locking device include positioning pin, torsional spring, drawstring and reset spring, and positioning pin is slidably disposed within frame
Interior, torsional spring is rotationally located on frame, and the first free end of torsional spring is connect with drawstring inner termination, and the second free end of torsional spring is suppressed fixed
Position pin external end head, reset spring are located between positioning pin and frame, and the corresponding seat frame of positioning pin inner termination is equipped with a groove,
Groove is along seat frame front-rear direction horizontal extension.
The drawstring external end head is connect with spanner, and friction cooperates so as to pull between its inner termination and seat frame after spanner rotation
Hand remains stationary.
Under the active force of drawstring or reset spring, positioning pin inner termination passes in and out groove.
It is slidably connected between the frame and fixed frame.
Frame two sidewalls outer surface respectively forms an arc-shaped pit, and corresponding seat frame two sides are respectively provided with a pivot,
Pivot is located in pit, is locked between pivot and frame with bolt.
Frame surface below the positioning column is equipped with recess, and positioning column is suppressed in recess by elastic component.
The utility model realizes that seat front end is leaned forward downwards, meets the specific demand of some users, and the adjusting knot that leans forward
Structure is simple, it is not easy to damage, it is convenient to lock when not needing to lean forward.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment, in conjunction with attached drawing, a kind of structure that leans forward of seat, including seat frame 1, seat cushion (not shown), frame 2
With fixed frame 3, seat cushion is mounted on seat frame, and seat frame 1 is located at 2 top of frame, and 1 middle part of seat frame is rotatablely connected with frame 2,
Rotation connection is by respectively forming an arc-shaped pit 4 in 2 two sidewalls outer surface of frame, and corresponding 1 two sides of seat frame are respectively provided with
One pivot 5, pivot 5 are located in pit 4, are locked between pivot and frame with bolt, and when seat frame leans forward, pivot turns in pit
It is dynamic.
Positioning column 6 is stretched out in 1 rear end sides face of seat frame respectively inwards, and 2 surface of frame of 6 lower section of positioning column is equipped with recess 7,
Positioning column 6 relies in recess 7, and frame surface is fixed with elastic component 8, and 8 other end of elastic component is suppressed in 6 top surface of positioning column, chair
1 front end opposing frame 2 of seat frame is hanging, and the seat that frame 2 slides is located on fixed frame 3, and fixed frame is mounted on the lifting of support seat
(not shown) on bar can move horizontally between frame 2 and fixed frame 3.
Positioning pin 9, torsional spring 10, drawstring 11 and reset spring 12 are equipped in 2 body of frame, positioning pin 9 is slidably disposed within
In frame 2, torsional spring 10 is rotationally set on the frame 2, and 10 first free end of torsional spring is connect with 11 inner termination of drawstring, torsional spring 10 second
Free end is suppressed in 9 external end head of positioning pin, and reset spring 12 is located between positioning pin 9 and frame 2, and 9 inner termination of positioning pin is corresponding
Seat frame 1 be equipped with a groove 13, groove 13 is along seat frame front-rear direction horizontal extension.
11 external end head of drawstring is connect with spanner 14, is rotated up spanner 14, and drawstring 11 is tensioned, and torsional spring 10 first is freely
End rotation, torsional spring 10 rotate, and 10 second free end of torsional spring makes frame 2 and seat frame in 9 inner termination of positioning pin push-in groove 13
1 locking, seat frame front end cannot have a down dip, spanner 14 rotate after between its inner termination 20 and the protrusion 21 of seat frame friction cooperate with
Remain stationary spanner.Again spanner is turned downwards, drawstring unclamps, and under the active force of reset spring, positioning pin inner termination is skidded off
Groove, seat frame front end can opposing frame dip down, positioning column 6 jacks up elastic component 8 at this time, but cannot break through elastic component 8 to
Under pressure.
