Abstract

The utility model relates to a mechanical arm. When a stretch button is pressed, a single-chip microcomputer controls a piston rod A of an electric push rod A to stretch out so as to push a casing pipe B to stretch outwards, and therefore the function of lengthening is achieved; after the mechanical arm is used, a return button is pressed, then the single-chip microcomputer controls the piston rod A of the electric push rod A to retract so as to drive the casing pipe B to retract. When an article needs to be clamped and taken, a tightening / loosening button is pressed, the single-chip microcomputer controls an electric push rod B to drive a driving device so as to enable a left clamping arm body and a right clamping arm body to rotate simultaneously towards the inside, and therefore the article is tightened. When the tightening / loosening button is pressed again, the single-chip microcomputer controls the electric push rod B to drive the driving device so as to enable the left clamping arm body and the right clamping arm body to rotate simultaneously towards the outside, and therefore the clamped article is loosened. At the time, a user can pick up articles far away through the mechanical arm, and therefore the mechanical arm is convenient and fast to use.

Description

A kind of mechanical arm

Technical field

The utility model relates to the one way of life articles for use, is specifically related to a kind of mechanical arm.

Background technology

Now a lot of disabled persons, and the old man of legs and feet inconvenience often runs into the situation of being inconvenient to pick up the distant place article or being difficult for bending over to pick article on the ground in life.If it is stretched forward reluctantly or bends to pick up article, easily be thrown to cause the damage of health.

Summary of the invention

The utility model provides a kind of mechanical arm that can assist holding articles in order to overcome the deficiency of above technology.

The technical scheme that its technical problem that overcomes the utility model adopts is:

This mechanical arm, comprise sleeve A, be slidingly mounted on the sleeve pipe B in the sleeve A 1, be installed on the electric pushrod A in the sleeve A, be installed on the electric pushrod B among the sleeve pipe B, relatively rotate left jig arm and the right jig arm that is installed on sleeve pipe B below by rotating shaft A and rotating shaft B respectively, the head end of piston rod A on the described electric pushrod A is fixed on the sleeve pipe B, the head end of piston rod B on the described electric pushrod B is fixed on the drive unit, described drive unit drives left jig arm and right jig arm to the inside or laterally rotate simultaneously, described electric pushrod A and electric pushrod B are connected in single-chip microcomputer, are installed on the button that stretches out on the sleeve A, return button and step up release button and be connected in single-chip microcomputer.

Above-mentioned drive unit is upper shifting block and the lower shifting block that is installed on piston rod B head end, and the root of described left jig arm and right jig arm is between upper shifting block and lower shifting block.

In order to make things convenient for the elderly to pick and place small article, also comprise the magnifying glass that is installed on sleeve pipe B below.

The beneficial effects of the utility model are: when pressing when stretching out button, the piston rod A of Single-chip Controlling electric pushrod A stretches out, thereby it is protruding to promote sleeve pipe B, realized the effect that lengthens, after finishing using, return button by pressing, the piston rod A of Single-chip Controlling electric pushrod A retracts, thereby drive sleeve B retracts.When the needs clamping articles, step up release button by pressing, Single-chip Controlling electric pushrod B drives drive unit turns to the inside left jig arm and right jig arm simultaneously, realizes article are stepped up.Press again and step up release button Single-chip Controlling electric pushrod B and drive drive unit left jig arm and right jig arm are laterally rotated simultaneously, the article of clamping are unclamped in realization, this moment, people can finish picking up of article at a distance by this mechanical arm, and are convenient to use.

Fig. 3 is jig arm part-structure schematic diagram of the present utility model;

Among the figure, 1. sleeve A 2. sleeve pipe B 3. magnifying glasses 4. left jig arm 5. right jig arm 6. are stretched out button 7. and are return button 8. and step up 14. times shifting blocks of shifting block, 15. rotating shaft A, 16. rotating shaft B on the release button 9. electric pushrod A 10. piston rod A 11. electric pushrod B 12. piston rod B 13..

The specific embodiment

Be described further below in conjunction with accompanying drawing 1, accompanying

drawing

2,3 pairs of the utility model of accompanying drawing.

This mechanical arm, comprise sleeve A 1, be slidingly mounted on the sleeve pipe B 2 in the sleeve A 1, be installed on the electric pushrod A 9 in the sleeve A 1, be installed on the electric pushrod B 11 among the sleeve pipe B 2, relatively rotate left jig arm 4 and the right jig arm 5 that is installed on sleeve pipe B 2 belows by rotating shaft A 15 and rotating shaft B 16 respectively, the head end of piston rod A 10 on the described electric pushrod A 9 is fixed on the sleeve pipe B 2, the head end of piston rod B 12 on the described electric pushrod B 11 is fixed on the drive unit, described drive unit drives left jig arm 4 and right jig arm 5 to the inside or laterally rotate simultaneously, described electric pushrod A 9 and electric pushrod B 11 are connected in single-chip microcomputer, are installed on to stretch out button 6 on the sleeve A 1, return button 7 and step up release button 8 and be connected in single-chip microcomputer.When pressing when stretching out button 6, the piston rod A 10 of Single-chip Controlling electric pushrod A 9 stretches out, thereby it is protruding to promote sleeve pipe B 2, realized the effect that lengthens, after finishing using, return button 7 by pressing, the piston rod A 10 of Single-chip Controlling electric pushrod A 9 retracts, thereby drive sleeve B 2 retracts.When the needs clamping articles, step up release button 8 by pressing, Single-chip Controlling electric pushrod B 11 drives drive unit turns to the inside left jig arm 4 and right jig arm 5 simultaneously, realizes article are stepped up.Press again and step up release button 8 Single-chip Controlling electric pushrod B 11 and drive drive units left jig arm 4 and right jig arm 5 are laterally rotated simultaneously, the article of clamping are unclamped in realization, this moment, people can finish picking up of article at a distance by this mechanical arm, and are convenient to use.

Above-mentioned drive unit is upper shifting block 13 and the lower shifting block 14 that is installed on piston rod B 12 head ends, and the root of described left jig arm 4 and right jig arm 5 is between upper shifting block 13 and lower shifting block 14.As shown in Figure 3, when the piston rod B of electric pushrod B 11 12 was protruding, upper shifting block 13 promotes left jig arm 4 and right jig arm 5 laterally rotates around rotating shaft A 15 and rotating shaft B 16, and therefore two jig arm realize opening function.When the piston rod B 12 of electric pushrod B 11 inwardly retracted, the lower shifting block 14 left jig arm 4 of pulling and right jig arm 5 turned to the inside around rotating shaft A 15 and rotating shaft B 16, and therefore two jig arm realize stepping up function.

Also comprise the magnifying glass 3 that is installed on sleeve pipe B 2 belows.The elderly who has defective vision can conveniently observe by magnifying glass 3 and want the small article that picks and places, facilitates the use this mechanical arm and picks and places, and has further improved multifunctionality.
