Examples

Referring to fig. 1-5, the present embodiment provides a hardware pulley assembly, which includes a bracket 1 and a front wheel 12 disposed at the front end of the bracket 1, the bracket 1 is mounted at the bottom of a sliding door or a sliding window, when the bottom of the sliding door or the sliding window slides in a track, the bracket 1 and the front wheel 12 support the bottom of the sliding door or the sliding window, the front wheel 12 slides in the track to reduce the portability of the sliding door or the sliding window, a protruding plate 11 is disposed at the rear end of the bracket 1, two symmetrical rollers 2 are rotatably disposed on the outer wall of the protruding plate 11, a through pipe 21 is disposed between the two rollers 2, a through housing 23 is communicated with the outer wall of the through pipe 21, a connecting pipe 24 is communicated with the outer wall of the through housing 23, the end of the connecting pipe 24 penetrates into the bracket 1, and is communicated with two symmetrical air pipes 25, the two air pipes 25 are respectively disposed near the edge inside the bracket 1, when the through pipe 21 is ventilated, the air sequentially passes through a through hole 210, the through housing 23, the connecting pipe 24 and the air pipes 25, the dust is discharged from the opening of the outer wall of the air pipe 25, when the bracket 1 moves from the top of the track, the dust in the track below the bracket 1 is blown to the middle, the dust is gathered in the middle of the track, jolt caused by the rolling of the roller 2 on the dust is reduced, the outer wall of the roller 2 is provided with a plurality of chutes 20 communicated with the inner cavity of the roller, the chutes 20 are communicated with the through pipe 21, the insides of the chutes 20 are hermetically and slidably provided with piston rods 22, the upper ends of the piston rods 22 extend out of the chutes 20, and considering that the roller 2 is easy to drive a sliding door or a sliding window to jolt when rolling on an uneven track, the sliding door or the sliding window is easy to damage for a long time, therefore, the ends of the piston rods 22 extend out of the chutes 20 on the surface of the roller 2, the ends of the piston rods 22 are in contact with the bottom of the inner cavity of the track, the lower ends of the piston rods 22 are extruded into the chutes 20, air is extruded into the through pipe 21 under atmospheric pressure, realize the air through-hole 210, lead to shell 23 and connecting pipe 24, discharge from the opening part of trachea 25 outer wall, be favorable to gyro wheel 2 to roll and blow the dust in the track, reduce dust and corrode gyro wheel 2, improve life.

The utility model discloses when specifically using, support 1 supports sliding door or austral window, support front wheel 12 and gyro wheel 2 in the track that removes, the 22 tip contact track bottom of piston rod that makes 2 outer walls of gyro wheel, along with the dust leads to track bottom unevenness, can make piston rod 22 to the inside extrusion of spout 20, under atmospheric pressure, it is inside to extrude siphunculus 21 with the air, realize the air through-hole 210, lead to shell 23 and connecting tube 24, discharge from the opening part of trachea 25 outer wall, blow to the centre with the dust in the track of 1 below of support, make the dust gathering in the middle of the track, it rolls on the dust to reduce gyro wheel 2, it is more steady to make gyro wheel 2 drive sliding door or austral window, sliding sash remove.

Can know by the aforesaid, support 1 will be installed in sliding door or austral window, sliding sash bottom, and it is more light to conveniently make the sliding door remove, so there is mounting panel 10 at 1 top threaded connection of support, and mounting panel 10 is used for through bolt installing support 1, through screw thread with mounting panel 10 with sliding door bottom threaded connection, realize fixing support 1 in the sliding door bottom, when the sliding door moves inside the track, make support 1 be located inside the track, guarantee structural integrity.

Because the size of piston rod 22 is effective, the area on contact ground is less, the distance that leads to piston rod 22 tip extrusion air is limited, can not effectually blow the dust, therefore, the end connection that stretches out spout 20 at piston rod 22 has arc board 221, arc board 221 and 2 outer wall profile looks adaptations of gyro wheel, when rotating through gyro wheel 2, make arc board 221 contact the track earlier and drive piston rod 22 and slide in spout 20 is inside, because arc board 221 size is greater than piston rod 22 tip, can improve the gliding distance of piston rod 22 in spout 20, the effect of realizing the extrusion air is stronger.

If the arc plate 221 drives the piston rod 22 to slide into the sliding groove 20, the arc plate 221 cannot be reset when being far away from the ground, and the arc plate 221 cannot be reused, so that the spring 222 is fixedly connected between the inner surface of the arc plate 221 and the outer wall of the roller 2, the spring 222 is a spiral spring, the arc plate 221 drives the roller 2 to slide into the sliding groove 20, the spring 222 is compressed, when the arc plate 221 is far away from the ground, the piston rod 22 is driven to reset under the resilience force of the spring 222, and the next time of air blowing can be performed when the arc plate 221 is contacted with the ground conveniently.

Realize that trachea 25 blows the dust effect in the track of 1 bottom of support better, make trachea 25 outer wall equidistant seted up a plurality of openings, the opening tip all is equipped with the dust screen, can make the even dust that blows 1 inner chamber bottom of support of trachea 25 combustion gas through a plurality of openings, improves the dust and blows the scope, and inside the dust screen can prevent to get into trachea 25 when inhaling the dust and disturbing, improvement life.

In order to conveniently adjust the angle of blowing dust at the opening of the outer wall of the air pipe 25, the end part of the air pipe 25 is communicated with the connecting pipe 24 in a rotating mode, the end part of the air pipe 25 rotates inside the rotating sleeve at the end part of the connecting pipe 24, the air pipe 25 rotates at the end part of the connecting pipe 24, the angle of the opening of the outer wall of the air pipe 25 is adjusted, the angle of blowing and sucking dust disturbing track dust is conveniently adjusted, and the dust blowing and sucking effect is improved.

The utility model discloses five metals loose pulley assembly is when specifically using, through the screw thread with mounting panel 10 with move a bottom threaded connection, the realization is fixed support 1 in moving a bottom, support 1 supports and moves a door or austral window, support front wheel 12 and gyro wheel 2 in the track that removes, make trachea 25 rotate at connecting 24 tip, adjust the angle of blowing dust absorption disturbance track dust, along with the dust leads to the track bottom unsmooth, arc 221 contacts the track earlier and drives piston rod 22 and slide in spout 20 is inside, the compression of spring 222, piston rod 22 is to spout 20 inside extrusion, under atmospheric pressure, squeeze into siphunculus 21 inside with the air, realize the air through-hole 210, lead to shell 23 and connecting 24, discharge from the opening part of trachea 25 outer wall, blow to the centre with the dust in the track of support 1 below, make the dust gathering in the middle of track, reduce gyro wheel 2 and roll on the dust, make gyro wheel 2 drive move a door or austral window move more steadily, when arc 221 is far away from the ground, drive piston rod 22 under the resilience force, make things convenient next time blow gas contact board 221 and can make contact with the ground once more again.
