[0023] Please refer to Figures 1 - 5 As shown, a rust-removing steel wire brush for a grinding machine includes a body 1 and a movable protection component 2; a movable block 21 is installed on the movable protection component 2, and several linkage arms 22 are hinged around the movable block 21. The other ends of the several linkage arms 22 are respectively hinged with adjusting arms 23, and the other ends of the several adjusting arms 23 are respectively hinged with a connecting seat 25

[0024] During operation, by means of being hinged to each other, when the gap between the movable block 21 and the connecting seat 25 changes, the movable block 21 generates a linkage on the adjusting arm 23 through the linkage arm 22, so that one end of the adjusting arm 23 makes a circular movement around the hinge point of the connecting seat 25

[0025] Furthermore, a brush roller 11 is installed on the body 1, a steel wire 12 is fixedly installed at the bottom of the brush roller 11, and an output shaft 13 is movably installed on one side of the brush roller 11

[0026] During operation, the steel wire 12 is a brush that selects corresponding types of steel wires for different uses and selects brushes with different steel wire diameters. The steel wire has two types: straight wire and corrugated wire, and the thickness of the wire can be determined according to different needs

[0027] Furthermore, a fixed plate 24 is fixedly installed at the bottom of the adjusting arm 23, and a protection plate 26 is fixedly installed at the bottom of the fixed plate 24

[0028] During operation, the adjusting arm 23 makes a circular movement to drive the fixed plate 24 and the protection plate 26 at the other end to flip, so as to make corresponding changes according to the rust-removing requirements at different positions

[0029] Furthermore, two fixing seats 32 are fixedly installed at the top of the connecting seat 25. A worm 31 is movably installed between the two fixing seats 32. A knob 33 is fixedly installed on one side of the worm 31.

[0030] During operation, by fixing the worm 31 through the knob 33, it is convenient for the operator to rotate the worm 31. Under the cooperation of the connecting seat 25 and the fixing seat 32, the worm 31 is supported and limited at the same time.

[0031] Furthermore, one side of the worm 31 is drivingly connected to a worm gear 29. One side of the worm gear 29 penetrates and is fixedly installed with a threaded shaft 28. The bottom of the threaded shaft 28 is movably installed with a connecting seat 25.

[0032] During operation, through the cooperation of the worm 31 and the worm gear 29, there is a self-locking property between them. When the lead angle of the worm is less than the equivalent friction angle between the meshing teeth, the mechanism has a self-locking property and can achieve reverse self-locking, that is, only the worm 31 can drive the worm gear 29, and the worm gear 29 cannot drive the worm 31.

[0033] Furthermore, a threaded groove is opened at the bottom of the movable block 21 and is threadedly connected to the threaded shaft 28. A bearing 27 is fixedly installed at the bottom of the connecting seat 25.

[0034] During operation, when the threaded shaft 28 rotates, through the cooperation with the threaded groove opened in the movable block 21, the gap between the movable block 21 and the connecting seat 25 is correspondingly changed, thereby producing a linkage effect on the subsequent components.

[0035] Working principle: By rotating the knob 33 by the operator, the knob 33 drives the worm 31 to drive the worm gear 29. The worm gear 29 is fixed with a threaded shaft 28. The threaded groove opened in the movable block 21 is matched with the threaded shaft 28. The rotational movement of the threaded shaft 28 is converted into the linear movement of the movable block 21 in a threaded cooperation manner. At this time, the gap between the movable block 21 and the connecting seat 25 is adjusted and changed. The linkage arm 22 hinged to the movable block 21 produces a linkage on the adjusting arm 23, so that the adjusting arm 23 rotates around the hinge point of the connecting seat 25. During the rotation process, the fixed plate 24 and the connecting seat 25 at one end are driven to move correspondingly, so that the protective plate 26 specifically protects the operation of the main body 1.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
