Now be described in further detail in conjunction with the accompanying drawings:
By shown in Figure 1: a kind of fold concertina-wise chair, it is made up of seat support 8, the chair back 1, preceding vertical tube 7, back vertical tube 6, the chair back 1 two ends are fixed in the joint of preceding vertical tube 7, back vertical tube 6 respectively, the rear portion of seat support 8 is affixed with back vertical tube 6 by rear cross-tube 15, the middle part of seat support 8 is affixed with back vertical tube 7 by preceding transverse tube 11, there is the moving pipe 5 of the axle of band piston back vertical tube 6 inside, and back vertical tube 6 is fixed together with preceding vertical tube 7, chair with back 1 by moving block 2, bearing pin 12 by the moving pipe 5 of axle.
By shown in Figure 2: top, two preceding vertical tube 7 tops is respectively arranged with a concave arc morpheme, the built-in nut 23 of concave arc morpheme, the port of nut 23 is parallel spill, when bearing pin 12 passes the chair back 1 end and moving block 2 horizontal circular holes, before the head of bearing pin 12 just is placed in the arcs of recesses at top, vertical tube 7 top by its tight connecting, pass the built-in nut 23 of bearing pin 12 head preformed hole positions and concave arc morpheme with bolt 14 then and closely link to each other.The chair back 1 and bracing frame are with regard to firm linking together like this.
Bearing pin 12 connects the chair back 1, preceding vertical tube 7 tops, the moving pipe of axle 5 tops, and there is a groove bearing pin 12 rear ends, in order to place spring 16 and pin key 17.After the bearing pin 12 of loading onto spring 16 and pin key 17 advances the stomidium of the chair back 1, spring 16 in the bearing pin 12 makes it be close to hole wall pin key 17 jack-up, and position, the chair back 1 both-end hole has been designed a concave arc morpheme respectively, and the concave arc morpheme is forward gradually dark, reverse gradually shallow parabolic shape.When counterclockwise rotating the chair back 1, pin key 17 can forward parabola, the rolling of arc recess wall be passed through along the chair back 1.Therefore counterclockwise rotating chair is unlucky, can 360 ° rotate freely, otherwise clockwise direction rotates the chair back 1, and pin key 17 is through the card shelves to the chair back 1 reverse parabolic arc recess, thereby the chair back 1 can not be rotated by clockwise direction.
Shown in Fig. 2,3: preceding vertical tube 7 tops are connected by nut 23, screw 14 with bearing pin 12, at connecting portion the Lobelia chinensis fixture block 3 of shape like half shell are arranged; Before vertical tube 7 middle-ends and preceding transverse tube 11 two ends, back vertical tube 6 middle-ends all are connected by nut 23, screw 14 with rear cross-tube 15 two ends, at connecting portion the seemingly partly fixture block 3 repeatedly of half shell of shape are arranged.
By shown in Figure 4: preceding transverse tube 11 two ends are respectively arranged with a concave arc morpheme, and the concave arc morpheme is a built-in nut 23 respectively.And seat support 8 bottom surfaces are provided with two round positions respectively, before current transverse tube 11 passes behind the round position its arc position, two ends two preceding vertical tubes 7 are coincide, the Kong Weihou of vertical tube 7 reservations before passing with bolt 14 then, the built-in nut 23 of bolt 14 and concave arc morpheme links to each other.Equally, rear cross-tube 15 two ends also are respectively arranged with a concave arc morpheme, the built-in nut 23 of difference in the concave arc morpheme, when rear cross-tube 15 passes behind the seat support 8 behind the round position, its arc position, two ends coincide vertical tube after two 6, after passing vertical tube 6 preformed hole positions, back with bolt 14 then, the built-in nut of bolt 14 and concave arc morpheme links to each other.Seat support 8, the chair back 1 and bracing frame are with regard to the firm formation chair that connects like this.
Spill locating piece 13 before the bottom surface of seat support 8 is fixed with and is installed on the transverse tube 11.
Shown in Fig. 5,6: the utility model is to serve as that design inspires with the work of the axis of the piston in cylinder, and each back vertical tube 6 is as an independent cylinder body, and the moving pipe 5 of axle and moving block 2, bearing pin 12, the chair back 1 that are matched with the band piston cylinder body in are rotationally connected.The lower end of the moving pipe 5 of axle is just being overlapped 20 by built-in pipe and is being linked to each other with back vertical tube 6, and the upper end of the moving pipe 5 of axle is just overlapping 20 and be positioned at the moving pipe pad sheet 22 that external pipe just overlapping 20 tops and link to each other with moving block 2 by external pipe.
When seat support 8 was amounted to, the power of amounting to was transmitted to being connected in the chair back 1, bearing pin 12, moving block 2 by preceding vertical tube 7, and the moving pipe 4 of pulling band the axis of the piston moves up, thereby vertical tube 7 relatively inwardly and move up before making, thereby chair is amounted to.Also because cylinder piston axle design, chair is amounted to after, can VO during quiet putting, eliminate safe hidden trouble.
By shown in Figure 7: vertical tube 6 bottoms all are with footmuff 9 behind two preceding vertical tubes 7 and two; footmuff 9 is built-in with slipmat 10 with ground contact surface; because footmuff 9, slipmat 10 and the powerful frictional force in ground, make the utility model place the unusual slip which kind of smooth ground all can be controlled.
Shown in Fig. 8,9: moving block 2 shapes respectively have a hole like semicircle in vertical direction and horizontal direction inside; The moving pipe of axle 5 tops connect by the Kong Weiyu moving block 2 of vertical direction in the moving block 2, and vertical tube 7 linked to each other before bearing pin 12 passed the Kong Weiyu of horizontal directions in the chair back 1 and the moving block 2, between preceding vertical tube 7 and the moving block 2 back-up ring 18 was arranged.After chair was amounted to, the moving pipe 5 of axle and 7 one-tenth two parallel straight lines of preceding vertical tube were in the same plane.Therefore, they can not form the folder corner cut, can not injure the person.
