Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-6, the present invention provides a technical solution: the utility model provides an escalator brush, includes the bar 1, one side integrated into one piece of bar 1 has strip arch 4, circular tube hole 2 has been seted up in the bar 1, arc notch 3 that is linked together with circular tube hole 2 has been seted up in the bar 1, trachea 5 has been seted up in the strip arch 4, recess 7 has evenly been seted up to the bottom of strip arch 4, the through-hole 6 that is linked together with trachea 5 is seted up to recess 7 inboard, the bottom of strip arch 4 is equipped with fly leaf 11, the top integrated into one piece of fly leaf 11 has inserted block 12, inserted block 12 inserts in recess 7, be equipped with pivot 8 in the circular tube hole 2, reel 9 has been cup jointed to the outside of pivot 8 fixed, the outside of reel 9 is fixed with brush hair 10, insert respectively in arc notch 3 and the recess 7 one side of brush hair 10.

Specifically, both ends of the strip-shaped body 1 are fixed to an outer ring of a bearing 15, and an inner ring of the bearing 15 is fixedly sleeved on the outer side of the rotating shaft 8; so that the bearing 15 can smoothly rotate. A rotating handle 17 is fixed at the outer end of the rotating shaft 8, a blind hole 19 is formed in the outer end of the strip-shaped body 1, and a positioning bolt 18 inserted into the blind hole 19 is connected to the outer side of the rotating handle 17 in a threaded manner; the rotating handle 17 can be locked to prevent the rotating handle 17 from freely rotating. The outer side of the winding drum 9 is uniformly fixed with a clapboard 16; preventing the bristles 10 from being entangled. A threaded rod 13 penetrating through the strip-shaped protrusion 4 is fixed at the top of the movable plate 11, and a nut 14 is connected to the top of the threaded rod 13 in a threaded manner; the position of the movable plate 11 is convenient to adjust. An air inlet port 20 communicated with the air pipe 5 is fixed at one end of the strip-shaped bulge 4; for facilitating the injection of gas into the gas tube 5.

The working principle or the structural principle is that when the escalator is used, the strip-shaped body 1 is fixed on the outer side of the escalator through the reserved screw holes which are inserted into the outer side by screws; when the length of the bristles 10 needs to be adjusted, firstly, the positioning bolts 18 are screwed and dismounted, so that the positioning bolts 18 are separated from the blind holes 19, then, the rotating handle 17 is rotated, the rotating handle 17 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the winding drum 9 to rotate, the winding drum 9 drives the bristles 10 to be retracted and released, the bristles 10 are made of hard nylon materials and have certain toughness, the bristles 10 can slide in the arc-shaped notches 3 and the grooves 7, the bristles 10 are observed when being adjusted, and the bristles 10 are prevented from being completely retracted into the arc-shaped notches 3; loosening the screw cap 14 to make the threaded rod 13 move downwards to drive the movable plate 11 to move downwards, and making the movable plate 11 move downwards to drive the inserting block 12 to move downwards, so that the bristles 10 can smoothly slide; when the bristles 10 can slide, the air inlet interface 20 can be connected with an air outlet of an external air pump to blow high-pressure air into the air pipe 5, so that the air is sprayed to the bristles 10 through the through holes 6 to blow off dust on the outer sides of the bristles 10, and the cleanliness of the bristles 10 is improved; tightening the nut 14, which secures the insert 12 to the bristle 10, locks the extended length of the bristle 10.
