Abstract
The utility model discloses a mechanism for adjusting the angle of a backrest. The mechanism comprises the backrest and a base, wherein the backrest is provided with a rotating shaft assembly which is connected with the base; the rotating shaft assembly is arranged on supporting holes corresponding to the base; more than one clamping groove is formed on the rotating shaft assembly of the backrest; an adjusting handle is arranged on one side of the base; the handle is provided with a limiting pin and is positioned in coordination with the clamping grooves of the rotating shaft assembly to adjust the relative angle between the backrest and the base; and the rotating shaft assembly is supported on the base through an elastic piece. According to the mechanism, the limiting pin on the handle is matched with different clamping grooves on the backrest through the adjusting handle, so that the aim of adjusting the angle is achieved; the angle of the backrest, which is suitable for a user, can be adjusted by the user according to different movement gestures of the user; and the mechanism has the advantages of convenience in adjustment, disassembly, maintenance and the like.
Description
Technical field
The utility model discloses a kind of backrest angle regulating mechanism, divides by International Patent Classification (IPC) (IPC) to belong to the backrest adjustment technical field, applicable to seat or lazybacks such as body-building apparatus, recreation cars.
Background technology
Present body-building apparatus or recreation seat such as car or lazyback often are designed to fixed sturcture; Can not adjusting angle; The user is seated at above-mentioned vehicle seat and carries out body-building or recreation, but because backrest and seat surface angle immobilize, has limited the motion posture of user when body-building or recreation.Simultaneously, because in a single day the backrest of conventional fixed structure damages, the dismounting maintenance is extremely inconvenient.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of backrest angle regulating mechanism rational in infrastructure, easy to use.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of backrest angle regulating mechanism comprises backrest and base, and said backrest has the rotating shaft assembly that links to each other with base; This rotating shaft assembly is set up on the cooresponding supported hole of base; The rotating shaft assembly of backrest is provided with more than one draw-in groove, and base one side is equipped with regulating handle, and this handle has a locating dowel pin and cooperates the location to regulate backrest and base relative angle with the draw-in groove of rotating shaft assembly; Described rotating shaft assembly is supported on the base by elastic component, and purpose makes backrest receive the thrust to base the place ahead all the time.
Further, at least one end has the card wheel on the described rotating shaft assembly, and this card wheel edge is provided with more than one draw-in groove to locate with the locating dowel pin of regulating handle.
Further, the joint that extends back in the middle of the described rotating shaft assembly, this joint links to each other with adjust bar, and the adjust bar other end links to each other with an expansion link through a stage clip, and described expansion link bottom is fixed on the base.
Further, described regulating handle is articulated in base one side, and the up and down locating dowel pin of holding in addition with driving handle cooperates with the draw-in groove of rotating shaft assembly or separates this handle around the hinged place, and described regulating handle is connected on the base through extension spring.
Further, described rotating shaft assembly is installed on two supported holes of base and by impulse bearing and fixes.
The utility model through regulating handle make on the handle locating dowel pin with lean against different draw-in grooves and cooperate; Reach the purpose of adjusting angle; Use this mechanism; The angle that product leans against can be regulated, and the user is fit to the own angle that leans against according to own different motion posture adjustment, have easy to adjust, dismantle advantages such as easy to maintenance.

Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model lateral plan.
Fig. 3 is the utility model exploded drawings.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 1 to Fig. 3; A kind of backrest angle regulating mechanism comprises backrest 1 and base 3, and said backrest has the rotating shaft assembly 10 that links to each other with base; This rotating shaft assembly is set up on the base 3 cooresponding supported holes; The rotating shaft assembly of backrest is provided with more than one draw-in groove 101, and base 3 one sides are equipped with regulating handle 8, and this handle has a locating dowel pin 81 and cooperates the location to regulate backrest and base relative angle with the draw-in groove 101 of rotating shaft assembly; Described rotating shaft assembly 10 is supported on the base 3 by elastic component, and purpose makes backrest receive the thrust to base the place ahead all the time.At least one end has the card wheel on the rotating shaft assembly, and this card wheel edge is provided with more than one draw-in groove to locate with the locating dowel pin of regulating handle.The rotating shaft assembly 10 middle joints 102 that extend back, this joint links to each other with adjust bar 4, and the adjust bar other end links to each other with an expansion link 6 through a stage clip 5, and described expansion link bottom is fixed on the base 3.Regulating handle 8 is articulated in base one side, and the up and down locating dowel pin of holding in addition with driving handle cooperates with the draw-in groove of rotating shaft assembly or separates this handle around the hinged place, and described regulating handle is connected on the base 3 through extension spring 7.Rotating shaft assembly is installed on two supported holes of base and is fixing by impulse bearing 2.
A kind of novel angle adjusting mechanism that leans against of the utility model; Comprise lean against 1, impulse bearing PFT204, base 3, adjust bar 4, stage clip 5, expansion link 6, extension spring 7, regulating handle 8; Through regulating handle 8 the spacing pin on it is cooperated with the different draw-in grooves that lean against the card wheel, reach the purpose of adjusting angle.Use this mechanism, the angle that product leans against, the user is fit to oneself the angle that leans against according to own different motion posture adjustment, and is easy to adjust, and dismantles easy to maintenance.
The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
