Description

FIELD OF THE INVENTION

The invention relates to medical equipment industry and, more particularly, to an angle rotation controlling device of a medical solution transfer system.

DESCRIPTION OF THE RELATED ART

Currently, most racks used for hanging the bottle of medical solution are composed of a main pole and side brackets protruding from the main pole. When patients need to be transferred, the transfer may not be easily to carry out, because the rack is too big or too high. As a result, the transfer time and efficiency may be affected, and the pain of patients will be increased.

An object of the invention is to provide an angle rotation controlling device which is easily moved, rotatable, and height adjustable.

To solve the technical problem described above, the invention provides an angle rotation controlling device including a main pole. A left arm and a right arm are assembled on the main pole, and both of the left arm and the right arm can be rotated around the axis of the main pole. Two vertical rods are assembled at an end of left arm and right arm, respectively. A left arm tooth disc is assembled at a left arm's end which is coaxial with the main pole. The right arm tooth disc which is matched with the left arm tooth disc is assembled at a right arm's end which is coaxial with the main pole. The left arm tooth disc and right arm tooth disc are assembled on the main pole via a knob.

In order to fasten the main pole, the left arm and the right arm, a main pole tooth disc is fixed at the bottom of the main pole to cooperate with the left arm tooth disc.

In order to easily replace the main pole tooth disc, the left arm tooth disc and the right arm tooth disc when they have abrasion, the right arm tooth disc is connected with the right arm via a fixing screw. The left arm tooth disc is connected with the left arm via a positioning screw and protrusions at both sides. The main pole tooth disc is fastened to the main pole via a pin.

In order to assure the height adjustability of the vertical rod, the vertical rod includes a fixing rod outside, and a telescopic rod inside.

In order to easily position the telescopic rod in the fixing rod, a pull button is disposed at the top of the telescopic rod, and an extraversive spring sheet(s) is(are) disposed at the body of the telescopic rod. The extraversive part of the spring sheet(s) is(are) connected with the pull button, and the amount of the spring sheet(s) described above is at least one.

In order to make the vertical rod stable in the vertical direction, the left arm includes lower left arm(s) and upper left arm(s), and the amount of the upper left arm(s) is at least one. The right arm includes lower right arm(s) and upper right arm(s), and the amount of the upper right arm(s) is at least one.

The benefit of this invention lies in: by utilizing the structure described above, the angle rotation controlling device can not only make the left arm and the right arm rotate relatively, but also can make the left arm and the right arm rotate around the main pole while the left arm and the right arm are stationary relative to each other. The height can be adjusted at will, and the doctors and nurses can move the patients easily.

DETAILED DESCRIPTION OF THE EMBODIMENTS

As shown in FIG. 1, FIG. 2 and FIG. 3, an angle rotation controlling device includes a main pole 3, and a left arm and a right arm are assembled on the main pole 3. Both of the left arm and the right arm are rotatable around the axis of the main pole 3. Two vertical rods 14 are assembled at an end of left arm and right arm, respectively. A left arm tooth disc 9 is assembled at a left arm's end which is coaxial with the main pole 3, and a right arm tooth disc 8 which is matched with the left arm tooth disc 9 is assembled at a right arm's end which is coaxial with the main pole 3. The left arm tooth disc 9 and the right arm tooth disc 8 are assembled on the main pole 3 via a knob 10. A main pole tooth disc 5 is fixed at the bottom of the main pole 3 to cooperate with the left arm tooth disc 9. The right arm tooth disc 8 is connected with the right arm via a fixing screw 12. The left arm tooth disc 9 is connected with the left arm via a positioning screw 11 and protrusions at both sides. The main pole tooth disc 5 is fixed to the main pole 3 via a pin 4. The vertical rod 14 includes a fixing rod 14-2 outside, and a telescopic rod 14-1 inside. The left arm includes lower left arm(s) 7 and upper left arm(s) 1, and the amount of the upper left arm(s) 1 is at least one. The right arm includes lower right arm(s) 6 and upper right arm(s) 2, and the amount of the upper right arm(s) 2 is at least one.

When the knob 10 located at the bottom of the angle rotation controlling device is completely loosened, the upper left arm 1, the lower left arm 7, the upper right arm 2 and the lower right arm 6 do not stay close to the main pole 3. At that moment the teeth of the left arm tooth disc 9, the right arm tooth disc 8 and the main pole tooth disc 5 are completely separated, and the separate rotations of the upper left arm 1, the lower left arm 7, the upper right arm 2 and the lower right arm 6 around the main pole 3 are not affected. When the knob 10 is fastened, the left arm tooth disc 9 and right arm tooth disc 8 stay close to each other, but the main pole tooth disc 5 does not stay close to the left arm tooth disc 9 and right arm tooth disc 8. As a result, a fixed angle is formed between the upper left arm 1 and the lower left arm 7, and between the upper right arm 2 and the lower right arm 6, but the combination of the upper left arm 1 and the lower left arm 7 and the combination of the upper right arm 2 and the lower right arm 6 can still rotate around the main pole 3. When the knob 10 is further fastened, the main pole tooth disc 5 and the left arm tooth disc 9 stay close to each other, so as to make all the upper left arm 1, the lower left arm 7, the upper right arm 2 and the lower right arm 6 fastened tightly to the main pole 3. When there is a need to adjust the angle and the position, the user only needs to loosen the knob 10, rotate the upper left arm 1, the lower left arm 7, the upper right arm 2 and the lower right arm 6 to a fixed position, and then fasten the knob 10 to achieve the desired results. A bottle hook 15 is disposed at the top of the vertical rod 14 for hanging the bottle of medical solution conveniently.

As shown in FIG. 4, a pull button 18 is disposed at the top of the telescopic rod 14-1, and extraversive spring sheet(s) 17 is(are) disposed on the body of the telescopic rod 14-1. The extraversive part of the spring sheet(s) 17 is(are) connected with the pull button 18. In the invention, the amount of the spring sheet(s) 17 described above is at least one.

When the vertical rod 14 is operated, the user only needs to lift the pull button 18, and the pull button 18 drives the spring sheet 17 to shrink inwardly, so the telescopic rod 14-1 can be moved upwardly or downwardly. When the needed position is arrived, the user only needs to release the pull button 18, the spring sheet 17 recovers to the original shape, and is clipped to the fixing rod 14-2, so that the height adjustment is finished.
