Specific embodiment
It, below will control in order to illustrate more clearly of the utility model embodiment and/or technical solution in the prior art
Detailed description of the invention specific embodiment of the present utility model.It should be evident that the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also basis
These attached drawings obtain other attached drawings, and obtain other embodiments.In addition, between being related to the belonging to and only indicate each component of orientation
Relative positional relationship, rather than absolute positional relation.
As shown in figs. 1 and 2.The racing car chair of the utility model embodiment, equipped with the backrest 1 and chair for meeting body mechanics' requirement
Seat 2 adjusts 1 angle of backrest in order to facilitate, and the utility model includes the first fixing piece 3 for being fixedly arranged on the backrest 1, fixed
In the second fixing piece 4 of the seat 2, two ends are connected to first fixing piece 3, the second fixing piece 4 and can be in backrest 1 respectively
To far from seat 2 direction overturn when so that backrest 1 is set back torsional spring 41, two ends be connected to respectively first fixing piece 3,
Second fixing piece 4 and the adjustable spring 42 to make backrest 1 set back when backrest 1 is to close to the overturning of 2 direction of seat.
The first fixing piece 3 in the utility model includes the projection piece 33 with aperture set on one end, the adjustable spring
The aperture that 42 one end pass through the projection piece 33 is connected with first fixing piece 3, when to close to 2 direction invertible back support 1 of seat
When, the adjustable spring 42 can be elongated and generate the pulling force for making first fixing piece 3 set back, and then can prevent from adjusting
Driver is set not feel good too close seat 2 that backrest 1 is adjusted when backrest 1；Second fixing piece 4 is equipped with and is adjustable institute
The spring-loaded governor 43 of 42 elasticity of adjustable spring is stated, the spring-loaded governor 43 can pass through the fixation adjustable spring 42
Different parts have controlled the length of the spring of stretching action, when the spring that plays stretching action is shorter compared with degree and backrest 1 is along leaning on
When nearly 2 direction of seat rotation equal angular, adjustable spring 42, which can generate bigger pulling force, makes 1 homing of backrest, but adjusts
It is too short can be unfavorable for the rotation of backrest 1, therefore driver can adjust described stretch by the spring-loaded governor 43 by oneself demand
Contracting spring 42.
The end of torsional spring 41 in the utility model is in hook-shaped, and first fixing piece 3 has release link 32, described
The end of torsional spring 41 can be hooked in the release link 32, when first fixing piece 3 is to far from the overturning of 2 direction of seat, institute
Stating release link 32 will push the end of the torsional spring 41 and the torsional spring 41 is made to generate restoring force, and then make described first to fix
Part 3 sets back, so that backrest 1 be enable to set back.
As shown in figures 2 and 3, the seat 2 in the utility model embodiment is connected with a screw rod 21,21 other end of screw rod
Affixed with second fixing piece 4,21 end surface of screw rod is smooth, end surface is threaded, and first fixing piece 3 is set
There are hole depth and 21 smooth part of screw rod tapped first through hole 31 consistent in length, to make first fixing piece
3 can overturn around 21 smooth part of screw rod, and then are able to drive the backrest 1 and overturn；It is also connected on the screw rod 21
Handle 22 is limited, the limit handle 22 includes the handle 24 set on one end, when the handle 24 is overturn to close to 2 direction of seat
When will drive limit handle 22 and be axially moved on screw rod 21 to push against first fixing piece 3, thus described in being able to cooperate
Second fixing piece fixes first fixing piece 3 from both ends.
The junction that the limit handle 22 is connected with screw rod 21 is equipped with externally threaded fixing nut 23, the fixing spiral shell
Mother 23 can be connected by external screw thread with the first through hole 31, will drive when the handle 24 is to close to the overturning of 2 direction of seat
The fixing nut 23 rotates, and enables in first through hole 31 described in the 23 part precession of fixing nut, to improve institute
The safety of racing car chair when stating limit handle 22 to the fixing degree of first fixing piece 3, and then improving racing car operation.
Second fixing piece 4 is equipped with stop bar 44, and the stop bar 44 can be by projection piece 33 described in backstop come only
Keep off the backrest 1, due to when driver drives backrest 1 with 2 angulation of seat is too big can seriously affect driving vision, thus institute
It states stop bar 44 and the backrest 1 is limited to 120 ° with maximum angle formed by seat 2.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
