Accompanying drawing 2 is A place enlarged drawings in accompanying drawing 1;
Accompanying drawing 3 is B place enlarged drawings in accompanying drawing 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of beddo bed board turnover mechanism of the present invention is described further.As Fig. 1, Fig. 2, shown in Fig. 3, a kind of beddo bed board turnover mechanism, the bed board 2 comprising bedstead 1 and be arranged on bedstead 1, see Fig. 1, bed board 2 is divided into some pieces of plate bodys, and should gemel connection be passed through between plate body, can bend to make bed board 2, that is make can swing between plate body by gemel connection, thus make beddo have better comfortableness, see Fig. 1, described bedstead 1 is fixed with and is fixed with connector 3 by attachment screw 16, connector 3 offers the hole body of fixed rotating shaft 4, described connector 3 is rotationally connected with rotating shaft 4, described rotating shaft 4 end is provided with axle sleeve 17, rotating shaft 4 is first assembled with axle sleeve 17, and then axle sleeve 17 is assembled in hole body, rotating shaft 4, connector 3 can be obtained by metal material, axle sleeve 17 then should be obtained by plastic material, to reduce noise when rotating shaft 4 is rotated, described bedstead 1 is also provided with the drive unit that drive shaft 4 is rotated, this drive unit is hydraulic cylinder 10, described hydraulic cylinder 10 is fixed on bedstead 1, described rotating shaft 4 is fixed with the body of rod 5 stirring bed board 2, described hydraulic cylinder 10 comprises piston rod 12, in described rotating shaft 4, cover is fixed with the fork 11 coordinated with piston rod 12, piston rod 12 should be with the connected mode of fork 11 and is rotationally connected, the rectilinear motion of piston rod 12 to be converted to by fork 11 gyration of rotating shaft 4, see Fig. 3, described fork 11 is provided with away from one end of rotating shaft 4 cell body 13 coordinated with piston rod 12, described piston rod 12 is fixed in cell body 13 by connecting pin 14,
Piston rod 12 stretches out or contraction bands movable pendulum bar 11 swings an angle value, and drive rotating shaft 4 to turn round an angle while fork 11 swings, and then make the body of rod 5 be fixed in rotating shaft 4 swing an angle, the swing of the body of rod 5 realizes bed board 2 and bends or tile; Bed board 2 can produce wearing and tearing between bending process king-rod body 5 and bed board 2, in order to reduce this wearing and tearing: see Fig. 2, the end of the described body of rod 5 is provided with the roller 6 reducing the body of rod 5 and bed board 2 coefficient of friction, described roller 6 is rotatably connected on the body of rod 5, the described body of rod 5 is provided with the groove 7 of fixed idler whell 6, described roller 6 is fixed in groove 7 by bearing pin 8, and the sidewall of described groove 7 is provided with the pin-and-hole 9 wearing bearing pin 8.
Fork 11, piston rod 12 and connecting pin 14 all belong to stressed member, therefore, fork 11, piston rod 12 and connecting pin 14 preferentially adopt metal material to obtain, in concrete use procedure, in order to reduce the noise produced when beddo uses, can on the surface of connecting pin 14 brushing one deck plastic layer, this plastic layer can avoid connecting pin 14 and fork 11 direct friction, thus the noise reduced when beddo uses, in addition, bearing pin 8 surface of fixed idler whell 6 also can brushing one deck plastic layer, and 6, roller can be obtained by plastic material.
In said structure, fork 11 is driven to swing by hydraulic cylinder 10, fork 11 rotating shaft 4 while swing is turned round with fork 11, and the rod member be fixed in rotating shaft 4 also can swing thereupon, rod member contacts with the plate body forming bed board 2, interfere with plate body when rod member swings, thus promotion plate body makes it bend; And the body of rod 5 is particularly violent with the wearing and tearing of bed board 2 in this process, although rod member is provided with roller 6, but still can produce wearing and tearing after bed board 2 Long-Time Service, and in order to extend the service life of bed board 2, bed board 2 should be avoided to occur the situation of concentrated wear, and that is, the position that the body of rod 5 contacts with bed board 2 once should change every a period of time, to make bed board 2 can uniform wear, extend the service life of bed board 2; For this reason, the described body of rod 5 can be fixed in rotating shaft 4 in the following manner: described rotating shaft 4 is provided with at least two bodies of rod 5, two bodies of rod 5 can improve the stability of bed board 2, bed board 2 uniform force, the shape of cross section of the described body of rod 5 is polygon, and be provided with at least one connecting rod 15 between adjacent two bodies of rod 5, described connecting rod 15 can weld together with the body of rod 5, the shape of cross section of described connecting rod 15 is polygon, and above-mentioned polygon can be quadrangle, pentagon, hexagon etc.; The described body of rod 5 is provided with the mating holes coordinated with rotating shaft 4, the described body of rod 5 is also provided with the lock-screw be locked at by the body of rod 5 in rotating shaft 4, the described body of rod 5 is provided with the screw coordinated with lock-screw, described screw communicates with mating holes, described lock-screw is arranged with and carries out locking spring to lock-screw.The body of rod 5 is set in after in rotating shaft 4, is locked by lock-screw, and in order to ensure the stability of beddo, the body of rod 5 and rotating shaft 4 do not allow the phenomenon occurring skidding, and therefore, reply lock-screw carries out locking, as adopted the structure such as spring or spring shim.
Certainly, drive unit also can adopt other device to replace, as described in drive unit comprise drive motors, described rotating shaft 4 is provided with driven gear, described drive motors is connected with the driving gear engaged with driven gear.When rotating shaft 4 is driven by drive motors, the speed changer with auto-lock function should be provided with between drive motors and driving gear, can be locked in corresponding angle to make bed board 2, when adopting drive motors to drive, bed board 2 is swift in motion, but the complicated structure of beddo, the noise produced during beddo action is also greater than the noise that when adopting hydraulic cylinder 10 to drive, beddo produces, and therefore, in actual use procedure, prioritizing selection adopts hydraulic cylinder 10 to drive; Certainly, though cylinder is similar to the structure of hydraulic cylinder 10, during cylinder operation, noise is greater than hydraulic cylinder 10, therefore, although cylinder can replace hydraulic cylinder 10 to make drive unit, should be combined environment choose reasonable during concrete use.
Certainly, see Fig. 3, in actual design process, the body of rod 5 also can adopt following structure with coordinating of rotating shaft 4, and the described body of rod 5 is provided with the mating holes coordinated with rotating shaft 4, and the described body of rod 5 is set in after in rotating shaft 4 and is fixed in rotating shaft 4 by welding manner.The body of rod 5 and rotating shaft 4 are fixed together by welding manner, and the body of rod 5 is fixing reliable with rotating shaft 4, but the body of rod 5 can not change relative to the position of rotating shaft 4, therefore, should carry out choose reasonable as required when designing.
These are only the preferred embodiment of the present invention, being intended to embody outstanding technique effect of the present invention and advantage, is not the restriction to technical scheme of the present invention.Those skilled in the art will appreciate that all amendments made based on the technology of the present invention content, change or substitute technology feature, all should be covered by the technology category of claims of the present invention opinion.
