Description

Bionic clamping hand for special-shaped parts for department of infectious diseases

Technical Field

The utility model relates to a bionical centre gripping hand of abnormal shape piece for infectious diseases department.

Background

The patients in the infectious department of hospitals are mostly infectious germs, and the medical care personnel are not suitable for contacting the patients too much. But many sessions, whether testing, medical, nursing or inspection, require medical personnel to come into contact with the patient. Therefore, as an infectious department, a large amount of mechanical equipment is needed to be used for contacting patients instead of medical staff.

However, the various robots developed at present have a common disadvantage that they cannot hold objects of all shapes. The reason is that human fingers can hold objects with various shapes, but the shape of the mechanical arm is not bionic. Therefore, a bionic clamping hand needs to be developed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide a bionical centre gripping hand that infectious department used. In order to solve the problem, the utility model adopts the following technical scheme:

a bionic clamping hand for special-shaped parts for infectious diseases department comprises a forefinger component, a thumb component, a middle finger component and an installation part;

the index finger component comprises an index finger first bending part, an index finger second bending part and an index finger driving part which are connected in turn in a rotating way,

the thumb component comprises a first thumb bending part, a second thumb bending part and a thumb driving part which are connected in sequence in a rotating manner; the thumb component is arranged right below the index finger component, and the rotating direction of the thumb component is opposite to that of the index finger component; the rear part of the thumb driving part is provided with a mounting part;

the middle finger assembly comprises a middle finger first bending part, a middle finger second bending part and a middle finger driving part which are sequentially connected in a rotating manner; the middle finger assembly is arranged on the same horizontal plane of the index finger assembly, and the bending direction of the middle finger assembly is the same as that of the index finger assembly.

Furthermore, the first bending parts of the index finger assembly, the thumb assembly and the middle finger assembly have the same structure and are flat plates, and the front ends of the first bending parts are arc surfaces.

Furthermore, the second bending parts of the index finger assembly, the thumb assembly and the middle finger assembly are identical in structure, one end of the second bending part is rotatably connected to the first bending part, and the other end of the second bending part is rotatably connected to the driving part.

Further, the index finger driving part, the thumb driving part and the middle finger driving part are internally provided with motors and signal receiving equipment for driving the first bending part and the second bending part.

Furthermore, the rear ends of the index finger driving part and the middle finger driving part are also provided with installation parts.

This centre gripping hand adopts bionic design, and forefinger subassembly and thumb subassembly can be to holding. The first bending part is in a wide and thick flat plate shape, and is convenient to use as a mobile platform. The auxiliary middle finger assembly is adopted, so that the area of the mobile platform can be increased.
