[0038] The present application is further described in detail below in conjunction with the accompanying drawings.

[0039] Reference Figure 1 and Figure 3 , the embodiment of the present application discloses a movable hand support frame, comprising a main back plate 1, a clamping and fixing mechanism 2, an adjustment mechanism 3 and a hand support plate 4;

[0040] A main back plate 1, which is used to firmly clamp the fixing mechanism 2 and the adjusting mechanism 3;

[0041] A clamping and fixing mechanism 2, which is arranged on both sides of the main back plate 1, and is used to fix the device on one side of the hospital bed in use;

[0042] An adjustment mechanism 3, which is disposed on one side of the main back plate 1 and is used to adjust the use angle of the hand support plate 4;

[0043] The hand supporting board 4 is arranged at the top of the adjusting mechanism 3, and the hand supporting board 4 is used to support the patient's arm.

[0044] By setting the clamping and fixing mechanism 2, the device can be fixed in the use position to prevent the device from moving easily during its use, thereby improving the stability of the device and achieving a better hand support effect. By setting the adjustment mechanism 3, the inclination angle of the hand support plate 4 can be adjusted to adapt to the use of different patients. It has a wide range of applications and achieves better use effects.

[0045] Reference Figure 1 and Figure 4The clamping and fixing mechanism 2 also includes a driving worm 201, and a linkage worm wheel 202 is meshedly arranged on the outer side of the driving worm 201. The linkage worm wheel 202 is fixedly provided with a linkage half gear 203 through a connecting rod. Two linkage half gears 203 are provided, and the linkage half gears 203 are meshedly connected. The other end of the linkage half gears 203 is fixedly provided with a connecting rod A204, and the other side of the connecting rod A204 is rotatably provided with a clamping frame arm 206. The side of the clamping frame arms 206 close to each other is fixedly provided with a clamping plate 207. The connecting rod passes through and is rotatably arranged on one side of the main back plate 1. The driving worm 201 is rotatably arranged on one side of the main back plate 1, and a connecting rod B205 is rotatably arranged on the same side of the clamping frame arm 206. The linkage half gear 203 and the connecting rod B205 are rotatably arranged on one side of the main back plate 1.

[0046] The clamping plates 207 in the clamping and fixing mechanism 2 are placed on both sides of the bed guardrail, and then the driving worm 201 is rotated. The rotation of the driving worm 201 can drive the linkage worm wheel 202 to rotate, and the rotation of the linkage worm wheel 202 drives the linkage half gear 203 to rotate. The two linkage half gears 203 will rotate in opposite directions, and the rotation of the linkage half gear 203 drives the connecting rod A204 to rotate, so that the angle between the two connecting rods A204 becomes smaller and smaller, and at the same time, the angle between the connecting rods B205 will also become smaller and smaller, which is used to stabilize the use of the connecting rod A204. At the same time, the clamping plates 207 will approach each other and clamp on both sides of the guardrail, thereby fixing the device to prevent the device from moving easily during use, and making it more stable during use.

[0047] Reference Figure 1 and Figure 2 A stabilizing block 101 is fixedly provided on one side of the main back plate 1, a stabilizing rotating rod 401 is fixedly provided on one side of the hand support plate 4, the stabilizing rotating rod 401 penetrates and is rotatably provided on one side of the stabilizing block 101, and a protective layer is provided on the top of the hand support plate 4, and the protective layer is made of rubber material.

[0048] The provision of the stabilizing block 101 facilitates the hand support plate 4 to be more stable during adjustment, and the provision of the protective layer facilitates the user to use it more comfortably.

[0049] Reference Figure 1 and Figure 5 The adjustment mechanism 3 also includes an adjusting long screw 301, the outer side of the adjusting long screw 301 is threadedly connected with a movable adjustment block 302, the movable adjustment block 302 is slidably set at the bottom end of the hand support plate 4, one end and the outer side of the one end of the adjusting long screw 301 are respectively rotatably set with a stable connecting frame 303 and a stable side frame 304, the stable connecting frame 303 and the stable side frame 304 are fixedly set on both sides of the main back plate 1, and the top of the movable adjustment block 302 is set as an inclined surface.

[0050] The use angle of the hand support board 4 can be adjusted according to different patients. The long adjusting screw 301 in the adjusting mechanism 3 is rotated. The rotation of the long adjusting screw 301 causes the movable adjustment block 302 to move, thereby raising one side of the hand support board 4. The setting of the stabilizing rotating rod 401 can limit the maximum adjustment angle of the hand support board 4, and can stabilize the adjustment of the hand support board 4 to prevent over-adjustment. After the adjustment is completed, the arm can be placed on the protective layer at the top of the hand support board 4. It is suitable for a wide range of people.

[0051] Working principle: put the device at the position where it needs to be used, such as on a bed, and place the clamping plates 207 in the clamping and fixing mechanism 2 on both sides of the bed guardrail, then rotate the driving worm 201, the rotation of the driving worm 201 can drive the linkage worm wheel 202 to rotate, the rotation of the linkage worm wheel 202 drives the linkage half gear 203 to rotate, the two linkage half gears 203 will rotate in opposite directions, the rotation of the linkage half gear 203 drives the connecting rod A204 to rotate, so that the angle between the two connecting rods A204 becomes smaller and smaller, and at the same time the angle between the connecting rods B205 will also become smaller and smaller, which is used to stabilize the use of the connecting rod A204, and at the same time the clamping plates 207 will approach each other and clamp on both sides of the guardrail, so as to fix the device to prevent the device from moving easily during use, and make it more stable during use;

[0052] Then, the use angle of the hand support board 4 is adjusted according to different patients, and the long adjusting screw 301 in the adjusting mechanism 3 is rotated. The rotation of the long adjusting screw 301 causes the movable adjustment block 302 to move, thereby raising one side of the hand support board 4. The setting of the stabilizing rotating rod 401 can limit the maximum adjustment angle of the hand support board 4, and can stabilize the adjustment of the hand support board 4 to prevent over-adjustment. After the adjustment is completed, the arm can be placed on the protective layer at the top of the hand support board 4. It is suitable for a wide range of people.
