Detailed Description

The invention will now be further described with reference to the accompanying drawings.

Example 1:

the clinical medicine support bracket as shown in fig. 1 and 2 comprises a base 1 with outward wheels 4, wherein one side of the base 1 is connected with a push handle 2, the base 1 supports a lifting rod 3, the upper end of the lifting rod 3 supports a support plate 5, the support plate 5 is hollow and is provided with a bevel gear, the bevel gear is formed by meshing a driving gear 6 and a driven gear 7, the driving gear 6 is coaxially connected with one end of a first transmission shaft 8, the other end of the first transmission shaft 8 is connected with a crank 9, the driven gear 7 is coaxially connected with one end of a second transmission shaft 10, and the other end of the second transmission shaft 10 is connected with a support rod 11 for supporting a medicine tray.

The transmission principle in this embodiment is: as shown in fig. 2, the arrow in the figure shows the gear rotation direction, and by artificial hand rocking handle 9, drive driving gear 6 through first transmission shaft 8 and move, driving gear 6 drives driven gear 7 rotatory, and then drives bracing piece 11 through second transmission shaft 10 and rotate to it is rotatory to drive the tray of using medicine, the taking of the medicine of being convenient for.

In this embodiment, a lifting manner of the lifting rod 3 is provided, as shown in fig. 3 and fig. 4, the lifting rod 3 includes a rod body 301, a first lifting rod 302, a second lifting rod 303, a driving steel cable 304 and a driven steel cable 305 are disposed inside the rod body 301, one end of the driving steel cable 304 is fixed at a point on the upper half of the inner side of the rod body 301, the other end of the driving steel cable is wound around a first upper fixed pulley 308, which is wound around the inner side of the rod body, from a first lower fixed pulley 306 and a second lower fixed pulley 307 disposed on the first lifting rod 302, and finally, the driving steel cable is wound around a second upper fixed pulley 309 to extend outside the rod body 301 to be connected to a hand-operated mechanism 12; two ends of the driven steel wire rope 305 are respectively fixed on the inner side wall of the rod body 301, the middle of the driven steel wire rope 305 passes through the third upper fixed pulley 310 and the fourth upper fixed pulley 311 on the first lifting rod 302 and the third lower fixed pulley 312 and the fourth lower fixed pulley 313 on the second lifting rod 303 to support the second lifting rod 303, so that the bottom end of the second lifting rod 303 is higher than that of the first lifting rod 302. Two ends of the driven steel wire rope 305 are respectively fixed on the side wall of the inner bottom end of the rod body 301.

As shown in fig. 3 and 4, when the hand-operated mechanism is shaken, the active wire rope is pulled out from the lift rod, and the first lift rod is lifted. When the driving steel wire rope lifts the first lifting rod, the driven steel wire rope lifts the second lifting rod along with the lifting of the upper fixed pulley of the first lifting rod. When the rod body is sleeved with a plurality of rods, the structure and the motion mode of the inner lifting rod are the same as those of the second lifting rod.

The tubular product cross-section of the body of rod among this embodiment, first lifter, second lifter adopts square cross-section. The pulley needs to be installed on the inner wall of the rod, a large installation plane is needed, and if a circular tube is selected, the pulley cannot be installed on the inner wall of the circular tube; and the bending-resistant section coefficient of the square shape is larger than that of the circular shape of the pipe with the same wall thickness and cross section. The mounting plane of the driving steel wire rope is in the middle plane of the first lifting rod, and the mounting plane of the driven steel wire rope is in the middle plane of the second lifting rod and is perpendicular to the mounting plane of the driving steel wire rope. The form can avoid the mutual crossing collision of the two steel wire ropes in the same plane.

In this embodiment, as shown in fig. 5, the hand-operated mechanism 12 includes a handle 1201, the handle 1201 is connected to a fixed gear 1202, the fixed gear 1202 is engaged with a driven gear 1203, the driven gear 1203 is coaxially connected to a rotating arm 1204, the rotating arm 1204 is coaxially connected to a winding drum 1205, the winding drum 1205 is wound with the driving cable 305, and the rotating arm 1204 is connected to a self-locking mechanism. In the present embodiment, the self-locking mechanism is selected as the ratchet mechanism 13.

The process that hand mechanism 12 controlled the lifter to promote as follows:

(1) lifting the lifting rod: the handle is shaken to rotate the gear, the rotating arm outputs at a certain speed multiplying ratio to drive the winding drum to rotate and wind the driving steel wire rope, and the winding drum is locked by the ratchet wheel and the pawl after the winding drum stops ascending;

(2) descending the lifting rod: the pawl is pressed down, the lifting rod automatically descends (namely rapidly descends) under the action of self weight, and the use requirement is met; the descending speed can be adjusted by adding point damping on the crank handle by hand.

The ratchet mechanism is one of common self-locking mechanisms and generally comprises a driving swing rod, a pawl, a ratchet wheel, a non-return pawl and a machine frame. The working principle of the ratchet mechanism is as follows: as shown in FIG. 6, a ratchet 1301 is fixed on the output shaft, and a rocker 1302 is freely sleeved on the ratchet shaft and can freely swing around the ratchet shaft. When the rotating arm swings anticlockwise, the backstop pawl 1303 prevents the ratchet wheel from rotating, the pawl 1304 hinged on the swinging arm slides on the tooth back of the ratchet wheel 1301, and when the swinging arm swings clockwise, the pawl 1304 is inserted into a ratchet wheel tooth groove to push the ratchet wheel to rotate for a certain angle. The ratchet wheel rotates unidirectionally and intermittently along with the reciprocating swing of the rocker.
