Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

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, this utility model main part is positioned at below floor, comprises tooth bar 7, motor 9, tooth rest 10, housing and multiple gear.Described gear is in housing, and be clear expression internal structure, housing is not shown in the drawings.The starting switch of described motor 9 is exposed to floor surface.

Described tooth bar 7 is vertically placed, and through the hole on floor, tooth bar 7 upper end is fixedly connected with axil holder 8, and described tooth bar 7 is meshed with a gear 1, and a gear 1 and No. two gears 2 form a duplicate gear jointly.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 described housing is provided with stopping means, and carried out the angle of limiting gear frame 10 rotation by stopping means, described stopping means can be spacing shelves.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 No. four gears 4 are fixedly connected with a coaxial pocket-wheel 11.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.

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: when patient goes to toilet, and axil holder 8 is placed in oxter, under the effect of body weight, drives patient slowly to sit down.Its concrete mode is: when patient is with carry-over bar 7 to decline by axil holder 8, a gear 1 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 patient stands, by the axil holder 8 of arm through tooth bar 7 lower end, actuating motor 9, drives patient slowly to stand by this device.Its concrete mode is: motor 9 drives No. three gears 3 to turn clockwise, and No. three gears 3 drive No. two gears 2 to be rotated counterclockwise, and a gear 1 is rotated counterclockwise simultaneously, and a gear 1 is with carry-over bar 7 slowly to rise; 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.
