The utility model content
The purpose of this utility model is to provide the seat of the rotatable adjusting of a kind of backrest inclination angle.
The purpose of this utility model is achieved in that a kind of seat, comprise seat support (1), chair pin (2), backrest (3) and bracing frame (4), bracing frame is located at the bottom of seat support (1), backrest (3) is installed in the top of bracing frame (4), it is characterized in that: described backrest (3) is installed in the top of bracing frame (4) by an elastic connecting device (5).
Described elastic connecting device (5) comprises elastic rubber fitting (50), rotating shaft (51) and tie down screw (52), offer through hole (40) on the top of support frame as described above (4), the bottom of described backrest (3) is provided with connecting plate (30), the front portion of connecting plate (30) is provided with the locating slot (31) of setting-in tie down screw (52) and the cover plate (53) of fixed rotating shaft (51), offer screwed hole (54) at the middle part of rotating shaft (51), the position that connecting plate (30) is positioned at screwed hole (54) offers the opening (55) that passes for tie down screw (52), the middle part of described elastic rubber fitting (50) offers clearance position (500), and tie down screw (52) passes through hole (40) successively, clearance position (500), be fixed on behind the opening (55) on the screwed hole (54) of rotating shaft (51).
The two ends of described rotating shaft (51) are provided with axle sleeve (56).
The back that described connecting plate (30) is positioned at locating slot (31) is provided with two arc convex (33) that vertically distribute, the position correspondence that the top of support frame as described above (4) is positioned at arc convex (33) is provided with two brace tables (41) of vertical distribution, and two brace tables (41) are positioned at clearance position (500) both sides of elastic rubber fitting (50).
Offer counterbore (501) on the described elastic rubber fitting (50), be provided with helical spring (6) in the counterbore (501).
Described elastic connecting device (5) is leaf spring, and an end of leaf spring is fixedlyed connected with the top of bracing frame (4), and the other end is connected with the back fixation of backrest (3).
Described elastic connecting device (5) is spring, and an end of spring is fixedlyed connected with the top of bracing frame (4), and the other end is connected with the back fixation of backrest (3).
Good effect of the present utility model: because backrest is installed in the top of bracing frame by an elastic connecting device, this structural design, the user is by self body weight compression elasticity jockey backward, make it produce strain, the user can be rotated very flexibly regulate backrest to desired tilt angle, and during backrest inclination, be pivot point with the elastic connecting device, the bustle that is positioned at the backrest bottom can move forward, support the waist of human body, realization chases after back of the body function, thereby improves user's comfortableness.If the movable connection structure of adjustable-angle is adopted in the bottom of bracing frame and seat support, then can further enlarge the angle of inclination of backrest.

The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing to seat described in the utility model.
As Fig. 1-shown in Figure 6, the described seat of present embodiment mainly is made up of seat support 1, chair pin 2, backrest 3 and bracing frame 4, and bracing frame 4 is located at the bottom of seat support 1, backrest 3 is installed in the top of bracing frame 4, and backrest 3 is installed in the top of bracing frame 4 by an elastic connecting device 5.Elastic connecting device 5 comprises elastic rubber fitting 50, rotating shaft 51 and tie down screw 52, and elastic rubber fitting 50 can adopt TPU material or rubber or elastoplast to make.Offer through hole 40 on the top of bracing frame 4, the bottom of backrest 3 is provided with connecting plate 30, the front portion of connecting plate 30 is provided with the locating slot 31 of setting-in tie down screw 52 and the cover plate 53 of fixed rotating shaft 51, offer screwed hole 54 at the middle part of rotating shaft 51, the position that connecting plate 30 is positioned at screwed hole 54 offers the opening 55 that passes for tie down screw 52, offer clearance position 500 at the middle part of elastic rubber fitting 50, tie down screw 52 is fixed on the screwed hole 54 of rotating shaft 51 after passing through hole 40, clearance position 500, opening 55 successively.In order to increase the flexibility of rotating shaft 51, the two ends of rotating shaft 51 are provided with axle sleeve 56, and the shape of the locating slot 31 of connecting plate 30 and the shape of axle sleeve 56 are complementary.In addition, in order to realize rotary steering, the back that is positioned at locating slot 31 at connecting plate 30 is provided with two arc convex 33 that vertically distribute, the position correspondence that is positioned at arc convex 33 on the top of bracing frame 4 is provided with two brace tables 41 of vertical distribution, two brace tables 41 are positioned at clearance position 500 both sides of elastic rubber fitting 50, this respective outer side edges mode can realize that the hypsokinesis of backrest is regulated, and can be to sides tapered.In order to prevent that elastic rubber fitting 50 from forming permanent deformation in the pressurized process frequently, follow the string, be preferably in and offer counterbore 501 on the elastic rubber fitting 50, be provided with helical spring 6 in the counterbore 501, can be as required, a plurality of counterbores are set, and the direction difference of offering according to counterbore 501, the outer end of helical spring 6 is resisted against connecting plate 30 or bracing frame 4.During the backrest hypsokinesis, helical spring 6 bears bigger pressure and the elastic force when resetting, and avoids elastic rubber fitting 50 overwork damages.Also counterbore 501 directly can be offered and be that through hole, the two ends of helical spring 6 are resisted against respectively on connecting plate 30 and the bracing frame 4.
