Abstract
Provided is a seat frame structure capable of being turned. The technical scheme is that the seat frame structure capable of being turned comprises a limit plate, a sleeve, a limit plate support, a spring, a left connection plate, a right connection plate, a seat cushion framework and a backrest framework. The seat cushion framework comprises a bottom frame, a seat frame and a base. When the bottom frame rotates to form a certain angle with the horizontal direction, a locking block in the middle of the left connection plate or the right connection plate slides into a locking slot on the limit plate, and the bottom frame is locked in position. If the bottom frame rotates upwards continuously, the locking block on the left connection plate or the right connection plate can be separated from the locking slot, and the bottom frame can be turned downwards to the horizontal level. The seat frame structure is simple in operation, reliable in locking and good in stability.

The specific embodiment
For clearly demonstrating the technical characterstic of this programme, through a specific embodiment, this programme is set forth below.
Shown in accompanying drawing, a kind of turning frame structure comprises positioning plate 7, sleeve 8, positioning plate support 3, spring 2, left connecting panel 10, right connecting panel 14, seat cushion framework, backrest skeleton 1; Said seat cushion framework comprises underframe 9, seat frame 6 and base 26; Captive joint with an end of left and right connecting panel 10,14 respectively near an end of backrest skeleton in the both sides of said underframe 9; The other end of said connecting panel 10,14 is hinged through bolt 11 and backrest skeleton 1, seat frame 6; Wherein, bolt 11 is the rotating shaft of connecting panel 10,14, and said seat frame 6 is captiveed joint with base 26; Said positioning plate support 3 is fixed on a side of backrest skeleton 1 bottom; Said sleeve 8 is captiveed joint with an end of positioning plate 7; Said positioning plate support 3 comprises that an end is through the left and right support plate 19,18 of connecting plate 19 bonded assemblys; The other end of left and right support plate 17,18 has pin-and-hole 20, has bearing pin 4 to pass pin-and-hole, sleeve 8 inner chambers of left supported plate 19, the pin-and-hole of right supported plate 18 successively, and the two ends of bearing pin 4 are fixing through split washer 5; Said positioning plate support 3 is captiveed joint with backrest skeleton 1 with bearing pin 4 relative ends and this end is captiveed joint with an end of said spring 2, and the other end of said spring 2 is captiveed joint near an end of sleeve 8 with said positioning plate 7; The other end of said positioning plate 7 is provided with locking fluting 16, and the left connecting panel 14 adjacent with said positioning plate support 3 or the middle part of right connecting panel 10 are provided with the lock dog 15 that cooperates with locking fluting 16;
When said underframe 9 rotates to the certain angle of horizontal direction; The lock dog 15 at said left connecting panel 10 or right connecting panel 14 middle parts slips in the locking fluting 16 on the positioning plate 7; Underframe 9 lockings are in place; Continue to rotate up underframe, the lock dog on left connecting panel or the right connecting panel can be thrown off locking fluting, the said underframe level of returning to of can overturning downwards.
Wherein, the backrest skeleton comprise cross sill 21, with the framework that cross sill 21 is captiveed joint, said positioning plate support 3 is fixed on a side of said cross sill 21.
Connecting panel 10,14 is S-type, and said connecting panel and underframe bonded assembly one end are provided with inside L shaped bending part 22, and there is L shaped bending protruding 23 at the middle part of said connecting panel.Positioning plate support 3 and spring bonded assembly one end are provided with the notch part 25 of shellproof spring-drop; Positioning plate 7 is provided with the notch part 24 that prevents that spring from coming off with spring bonded assembly one end.
The present invention is through the position that is provided with of lock dog on the adjusting connecting panel; Be that the scalable underframe is when rotating to the angle from the horizontal by needs; Lock dog and locking fluting cooperates realizes locking, and what adopt among the present invention is, when underframe rotate to the horizontal direction angle be 85 when spending; The lock dog at said left connecting panel or right connecting panel middle part slips in the locking fluting on the positioning plate, and the underframe locking is in place.
When implementing the present technique scheme, first positioning plate support 3 is welded on a side of backrest welding assembly 1 cross sill; Sleeve 8 is integrally welded with positioning plate 7, is assemblied in the centre of positioning plate support 3 through bearing pin 4, and bearing pin 4 passes sleeve 7, and positioning plate 7 can be rotated around bearing pin 4 flexibly, and bearing pin 4 two ends are fixed with split washer 5, in case the shotpin axle is deviate from; Positioning plate 7 one side band notch parts, the other end of opposite side and positioning plate support 3 is connected with spring 2, and positioning plate 7 and positioning plate support 3 are hung an end of springs, and a notch part is all arranged, and prevent that spring from deviating from; Connecting panel 10 1 ends and underframe 9 are welded into underframe welding assembly; Connecting panel 10 other ends are rotatably connected through bolt 11 and backrest, seat frame 6; Bolt 11 usefulness I type all-metal hexagonal jam nuts 12 and flat gasket 13 lockings; In case deviate from, and require connecting panel and underframe to rotate flexibly around bolt 1.
When Fig. 1 was the horizontal running condition of underframe 9, positioning plate 7 was in free state, do not contact with connecting panel 10, this moment spring 2 existing certain predetermincd tensions.Fig. 2 for underframe 9 when upwards overturning, positioning plate 8 slips into the breach locking with connecting panel 10 from touching, the effect of spring 2 tensile forces makes locking reliable; Like Fig. 3, Fig. 4, shown in Figure 5, represented lockable mechanism in operational process underframe welding assembly when level, locking, three states of release, the position of positioning plate and connecting panel and dissect signal.
Principle of work: rotating shaft (bolt 11) in-line not of rotating shaft (bearing pin 4) and the connecting panel of positioning plate is set, utilizes rotational trajectory different of rotational trajectory and the connecting panel of positioning plate, when underframe welding assembly rotates to from the horizontal by about 85 °; The lock dog (convexity) of lower end, connecting panel middle part is located to slip in the locking fluting of positioning plate lower end, under the effect of spring, receives force direction to become the dead point with the support direction; The underframe locking is in place, continues to rotate up underframe, and connecting panel is thrown off the longest point of positioning plate; Hear the sound of release, underframe is release, under the pulling force of spring; The positioning plate return is rotated down underframe and returns to level attitude.One of left side connecting panel, right connecting panel are provided with lockable mechanism and get final product.
The present invention can pass through or adopt existing techniques in realizing without the technical characterictic of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
