Detailed description of the invention

Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.

As shown in Figure 1, 2, this utility model comprises a body 14 and lifting part.Bed body 14 is provided with fixed bed board 18 and lifting bed board 16, and lifting bed board 16 is hinged by side and fixed bed board 18.Bed board has crossbeam 17.

For ease of describing, the direction at setting lifting bed board 16 place is front, after the direction at fixed bed board 18 place is.

Described lifting unit divides and comprises cabinet 8, tooth bar 7, connecting rod 15, motor 9, tooth rest 10 and multiple gear.Described gear, tooth rest 10 and motor 9 are positioned at cabinet 8.Described connecting rod 15 two ends are hinged with described lifting bed board 16 and tooth bar 7 respectively.Described tooth bar 7 passes cabinet 8, horizontal positioned.Described crossbeam 17 is provided with the hole along bed body 14 fore-and-aft direction trend, and described tooth bar 7 passes in hole.

As shown in Figure 2, tooth bar 7 is meshed with a gear 1, and a gear 1 and No. two gears 2 form a duplicate gear jointly, and the axle of duplicate gear is arranged on described cabinet 8.Described motor 9 output shaft connects No. three gears 3, No. three gears 3 and is meshed with described No. two gears 2.

The axle at described tooth rest 10 and a gear 1, No. two gear 2 places is hinged, and is carried out the angle of limiting gear frame 10 rotation by cabinet 8.Described motor 9 is fixedly connected with tooth rest 10.Because the axle of tooth rest 10 around No. two gear 2 places rotates, so in rotary course, No. three gears 3 can be meshed with No. two gears 2 all the time.

The below of No. two gears 2 is provided with No. four gears 4, No. four gears 4 and is meshed with No. two gears 2, and the axle that No. four gears 4 are fixedly connected with a coaxial pocket-wheel 11, No. four gears 4 and a pocket-wheel 11 is arranged on cabinet 8.Described tooth rest 10 is provided with intermeshing No. five gears 5 and No. six gears 6, No. five gears 5 are fixedly connected with coaxial No. two pocket-wheels 12 and No. three pocket-wheels 13 respectively with No. six gears 6.Three described pocket-wheels are positioned on same perpendicular, and meet: 1. No. two pocket-wheels 12 and No. three pocket-wheel 13 maximum radius (i.e. the spacing in sharp corner and the center of circle) sums are less than No. five gears 5 and No. six gear 6 reference radius sums, to ensure that No. two pocket-wheels 12 and No. three pocket-wheels 13 can not collide; 2., when tooth rest 10 rotates to lowest part, the wedge angle of the wedge angle of No. two pocket-wheels 12 and No. three pocket-wheels 13 can both collide with the wedge angle of a pocket-wheel 11; 3., when tooth rest 10 rotates to highest point, the wedge angle of the wedge angle of No. two pocket-wheels 12 and No. three pocket-wheels 13 all can not collide with the wedge angle of a pocket-wheel 11.Under gravity, during naturalness, tooth rest 10 is positioned at the lowest part of its stroke.

As shown in Figure 3, described tooth bar 7 is respectively provided with a lateral aperture moved towards along bed body 14 width with crossbeam 17, and be provided with fixture block 21 in the lateral aperture of tooth bar 7, fixture block 21 one end is exposed, and is provided with inclined-plane on rear side of bared end.Fixture block 21 other end is provided with spring 22.The lateral aperture of described crossbeam 17 is wherein connected with the hole at crossbeam 17 upper rack 7 place one end, and be provided with action bars 20 in crossbeam 17 lateral aperture, tooth bar 7 can be encountered in action bars 20 one end, and the other end exposes in hole, is convenient to user operation.

In prioritization scheme, for obtaining slowing effect better, gear 1 diameter is less than No. two gear 2 diameters, and No. two gear 2 diameters are greater than No. four gear 4 diameters, and No. four gear 4 diameters are less than the maximum gauge (i.e. the twice of the spacing in sharp corner and the center of circle) of a pocket-wheel 11.

Operating process is as follows: after lifting bed board 16 rises, described fixture block 21 is stuck in the lateral aperture on crossbeam 17, thus is fixed by tooth bar 7.When being elevated bed board 16 and needing to fall, push bar 20, push card is fast, under gravity, by lifting part, lifting bed board 16 is slowly fallen.Its concrete mode is: move after lifting bed board 16 promotes connecting rod 15, connecting rod 15 moves after promoting tooth bar 7, tooth bar 7 promotes a gear 1 and turns clockwise, No. two gears 2 turn clockwise simultaneously, No. two gears 2 drive No. four gears 4 to be rotated counterclockwise, a pocket-wheel 11 is rotated counterclockwise simultaneously, first pocket-wheel 11 wedge angle collides with No. two pocket-wheel 12 wedge angles, No. two pocket-wheels 12 turn clockwise, No. five gears 5 turn clockwise simultaneously, No. six gears 6 are driven to be rotated counterclockwise, No. three pocket-wheels 13 are rotated counterclockwise simultaneously, pocket-wheel 11 wedge angle collides with No. three pocket-wheels 13 be rotated counterclockwise immediately, No. three pocket-wheels 13 are reversed, namely turn clockwise, No. six gears 6 turn clockwise simultaneously, No. five gears 5 are driven to be rotated counterclockwise, No. two pocket-wheels 12 are rotated counterclockwise simultaneously, the next wedge angle of a pocket-wheel 11 collides with No. two pocket-wheels 12 be rotated counterclockwise immediately ... through the collision gone round and begun again, the rotating speed of a pocket-wheel 11 is controlled in a lower speed all the time, namely the process that tooth bar 7 slowly declines is achieved.

When needs rise lifting bed board 16, actuating motor 9, drives bed board slowly to rise by lowering or hoisting gear.Its concrete mode is: motor 9 drives No. three gears 3 to turn clockwise, No. three gears 3 drive No. two gears 2 to be rotated counterclockwise, a gear 1 is rotated counterclockwise simultaneously, and move after a gear 1 is with carry-over bar 7 slowly, lifting bed board 16 is risen by connecting rod 15 by tooth bar 7; Simultaneously No. three gears 3 are subject to the counterclockwise moment that No. two gears 2 act on, tooth rest 10 is subject to the clockwise moment that No. three gears 3 act on, this moment driven gear frame 10 rotates clockwise double dot dash line position in figure, now No. two pocket-wheels 12 and No. three pocket-wheels 13 no longer collide with a pocket-wheel 11, avoid energy loss.

The slow process of falling realizes mechanically, without the need to starting motor 9, thus reduces energy loss; Slow fall process by collision but not friction mode realize, coefficient of friction therefore can not be caused to change and then slow reduction of speed degree is changed because of the wearing and tearing of part, slow reduction of speed degree also can not produce larger difference because the body weight of user is different.

It should be noted that; particular of the present utility model has been described in detail this utility model; for a person skilled in the art, the various apparent change carried out it when not deviating from spirit and scope of the present utility model is all within protection domain of the present utility model.
