Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an auxiliary mechanical arm for hemiplegic patients with an anti-collision protection structure. Background Art

[0002] At present, the incidence of cerebrovascular diseases is increasing year by year, and the number of patients with hemiplegia caused by it is also gradually increasing. Hemiplegia usually causes paralysis of the upper and lower limbs on one side of the patient. Moreover, the paralyzed limbs of hemiplegic patients sometimes experience spasms, causing more pain to the patients. The existing anti-spasm methods are mostly to perform exercise training on the limbs and train through auxiliary robotic arms.

[0003] However, the prior art still has shortcomings. The auxiliary mechanical arm in the prior art lacks protection function and protection for the device.

[0004] Therefore, we propose an auxiliary robotic arm for hemiplegic patients with an anti-collision protection structure to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and to propose an auxiliary mechanical arm for hemiplegic patients with an anti-collision protection structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A hemiplegic patient auxiliary mechanical arm with an anti-collision protection structure comprises a mechanical arm shell; an installer is fixedly connected to the outer circumferential surface of the mechanical arm shell; a protective shell is fixedly connected to the outer surface of the installer; an anti-slip pad is fixedly connected to the outer circumferential surface of the protective shell; a partition compartment is provided between the protective shell and the mechanical arm shell; a sponge is fixedly connected to the inner circumferential surface of the protective shell.

[0008] Preferably, a slide groove is provided on the upper surface of the installer; a limit groove is provided on the inner surface of the installer; a No. 1 installation groove is provided on one side of the inner surface of the installer; a button is slidably installed on the inner surface of the slide groove; a limit block is fixedly connected to the outer surface of the button; and an auxiliary spring sheet is fixedly connected to the inner surface of the No. 1 installation groove.

[0009] Preferably, the outer surface of the limit block is slidably mounted on the inner surface of the limit groove; the limit groove is located on both sides of the slide groove; and the mounting groove is located on the lower side of the inner surface of one side of the slide groove.

[0010] Preferably, a mounting block is fixedly connected to the outer surface of one side of the protective shell; a No. 2 mounting groove is provided on the upper surface of the mounting block; a fixing block is slidably installed on the inner surface of the No. 2 mounting groove; and a reset spring sheet is fixedly connected to the lower surface of the fixing block.

[0011] Preferably, the fixed block is a trapezoidal block; the lower end of the reset spring sheet is fixedly connected to the inner bottom surface of the second mounting groove.

[0012] In the utility model, the auxiliary mechanical arm for hemiplegic patients with an anti-collision protection structure is provided through the arrangement of the mechanical arm shell, the installer, the slide groove, the limit groove, the button, the limit block, the protective shell, the mounting block, the No. 2 mounting groove, the fixed block, the reset spring sheet, the anti-skid pad, the sponge, and the spacer. When the protective shell is installed, the mounting block is first pushed into the slide groove, and the fixed block is squeezed into the No. 2 mounting groove by the slide groove, so that the reset spring sheet is compressed. When the mounting block is completely entered into the slide groove, the fixed block will move upward under the action of the rebound of the reset spring sheet, leave the No. 2 mounting groove and enter the slide groove to fix the mounting block, thereby completing the installation of the protective shell; when the protective shell is replaced, the button is pressed, and the movement of the button will push the fixed block downward, put the fixed block into the No. 2 mounting groove, and then take out the protective shell through the anti-skid pad to complete the disassembly, thereby improving efficiency;

[0013] In the utility model, the auxiliary mechanical arm for hemiplegic patients with an anti-collision protection structure is provided with a No. 1 mounting groove and an auxiliary spring sheet. When the mounting block enters the slide groove, the auxiliary spring sheet will be squeezed and compressed. When the mounting block needs to leave the slide groove, the auxiliary spring sheet assists the mounting block to move, thereby improving convenience.

[0014] The utility model has reasonable structural design, simple operation and high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
