Detailed Description

The attached drawings are the best embodiments of the dust hood for cleaning piano keys, and the invention is further described in detail with reference to the attached drawings.

Example 1:

a dust hood for cleaning piano keys comprises a dust hood 1, a connector 2 and a supporting device 3. The cross section of the dust hood 1 is isosceles trapezoid. Dust cage 1 length and piano key panel length the same, need not to remove dust cage 1 about like this in the practical process, labour saving and time saving. The dust hood is characterized in that an opening of the dust hood 1 is located below the dust hood, a connector 2 is connected to the upper portion of the dust hood 1 in a penetrating mode, a step 2a is arranged at the upper end of the connector 2, and a hose of a dust collector is sleeved on the step 2 a.

The left side and the right side of the dust hood 1 are respectively provided with a supporting device 3, and the two supporting devices 3 are symmetrically arranged. The supporting device 3 comprises a vertical rod 3a, a horizontal rod 3b and a rotating shaft 3 c. Horizontal pole 3b keep away from the downward fixedly connected with vertical pole 3a of one end of suction hood 1, horizontal pole 3b be close to the one end of suction hood 1 and be equipped with pivot 3c, pivot 3c rotate and locate inside the 1 curb plate of suction hood. The two sides of the rotating shaft 3c are respectively provided with a limiting baffle 3d, the two limiting baffles 3d are respectively positioned on the two sides of the side plate of the dust hood 1, and the rotating shaft 3c is prevented from being separated from the side plate of the dust hood 1. Meanwhile, a rotary groove 1a is formed in a side plate of the dust hood 1, the rotary shaft 3c is rotatably arranged in the rotary groove 1a, 6-10 convex points 3c1 are uniformly distributed on the circumferential surface of the rotary shaft 3c, a groove connected with the convex points 3c1 in a matched mode is formed in the circumferential surface of the rotary groove 1a in an inwards concave mode, and the convex points 3c1 are arranged in the groove. When the dust hood 1 is rotated, the convex points 3c1 are forced to be separated from the original remained groove and enter the next groove, so that the dust hood 1 can be effectively fixed.

The lower end of the vertical rod 3a is fixedly connected with a support frame 3e which is horizontally arranged, a screw rod 3f is arranged in the support frame 3e in a penetrating mode, the screw rod 3f is in threaded connection with the support frame 3e, and a top disc 3f1 is arranged at one end, facing the dust hood 1, of the screw rod 3 f. And a rubber pad 3f2 is arranged on one surface of the top disc 3f1 facing the dust hood 1. The two screws 3f are rotated so that the two top plates 3f1 move to the side of the piano, and the piano is pressed between the two top plates 3f1, and the dust hood 1 is fixed above the piano key panel.

The vertical rod 3a may be a telescopic rod, which helps to adjust the distance between the dust hood 1 and the piano keys.

Example 2:

the lower end of the vertical rod 3a is fixedly connected with a supporting seat 3g, and the supporting seat 3g is directly supported on the ground. Other undescribed structures in this embodiment are the same as those in embodiment 1.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge of those skilled in the art.
