Description

A new type of supine standing frame

Technical Field

The utility model relates to a novel supine-standing frame, belonging to the technical field of medical rehabilitation equipment.

Background Art

The supine standing frame is used for rehabilitation training of patients with cerebral palsy and other disabilities who have standing dysfunction. When the bed frame of the supine standing frame is laid flat in the supine position, the standing frame is fixed together with multiple parts of the patient's body with flexible straps, and then the bed frame is rotated to make the patient stand.

Existing supine-to-stand frames mostly use an electric drive to rotate the bed frame, which makes the patient's standing rehabilitation training very limited to the venue, and makes it impossible for the patient to choose a more comfortable and pleasant venue for rehabilitation training.

DETAILED DESCRIPTION

The present invention is further described in detail below in conjunction with specific embodiments:

As shown in Figures 1-4, a new supine standing frame comprises a support frame 1, a bed frame 2 rotatably arranged on the support frame 1, a headrest 3 and a body fixing assembly 4 are arranged on the bed frame 2, a bed frame flipping drive 5 is arranged between the support frame 1 and the bed frame 2, and the bed frame flipping drive 5 comprises a rotating shaft 51 arranged on the support frame 1, a worm gear group connected to the rotating shaft 51, a transmission connecting rod is arranged between the worm gear of the worm gear group and the bed frame 2, and a hand-cranked wheel 52 is arranged at both ends of the rotating shaft 51. When the utility model is used, no power supply is required, and an external force is applied to the hand-cranked wheel 52 to rotate it, thereby driving the rotating shaft 51 to rotate, and then one end of the bed frame 2 is lifted through the worm gear group and the transmission connecting rod, so that the bed frame 2 flips and rotates. In this way, the supine standing frame is not restricted by whether there is power supply in the venue, and the bed frame 2 can be manually driven to flip at any time. Preferably, the middle part of the bed frame 2 is hinged to the support frame 1 through a hinge shaft, and flipping is the most labor-saving and stable.

The rotating shaft 51 is sleeved with a first transmission gear 53, and the worm gear set includes a worm 54 and a worm wheel 55. One end of the worm 54 is provided with a second transmission gear 56 meshing with the first transmission gear 53, and the transmission connecting rod and the worm wheel 55 are connected through a worm wheel shaft 57. The transmission connecting rod finally applies force to flip the bed frame 2. When the hand-cranked wheel 52 stops rotating, the worm wheel 55 is locked with the worm 54, thereby fixing the flip angle of the bed frame 2, which is simple and reliable. Furthermore, bearings are arranged at some connecting parts of the rotating shaft to improve the stability and durability of the transmission.

In the present invention, the transmission connecting rod includes a first connecting rod 58 rotatably connected to the worm gear 55, and a second connecting rod 59 is rotatably connected between the first connecting rod 58 and the bed frame 2. Preferably, in order to ensure stable transmission between the worm gear 55 and the first connecting rod 58, there are two first connecting rods 58 connected to the two ends of the worm gear shaft 57 on both sides of the worm gear 55, and the second connecting rod 59 is connected between the two first connecting rods 58.

Furthermore, the rotating shaft 51 is sleeved with a driving seat body 50, and the worm gear assembly is arranged on the driving seat body 50, and the driving seat body 50 is arranged on the supporting base frame 1 to ensure the working stability of the bed frame turning drive 5. Preferably, the first transmission gear 53 and the second transmission gear 56 are both bevel gears, which have smoother transmission movement, less noise, and greater gear bearing capacity.

In the present invention, the body fixing assembly 4 includes a chest fixing assembly 41, a waist and abdomen fixing assembly 42, a leg fixing assembly 43 and a foot fixing assembly 44. The installation positions of the chest fixing assembly 41, the waist and abdomen fixing assembly 42, the leg fixing assembly 43 and the foot fixing assembly 44 can be adjusted to adapt to the patient's body shape, and the angle and spacing can also be adjusted. The place where the strip groove is connected to the screw can be adjusted, which can better correct the patient's body.

In order to facilitate the patient's meals, a dining board 6 is adjustably mounted on the bed frame 2; the supporting base frame 1 is provided with rollers 7, generally four in number, to facilitate pushing the patient to different places.
