Description

Technical Field

[0001] The utility model relates to a buffer structure, in particular to a piano cover buffer structure. Background Art

[0002] A piano consists of keys (including white keys and black keys) and a metal string soundboard. Usually, a piano is equipped with a piano cover to protect the keys. In order to prevent the piano cover from colliding with the piano body when closing, a damper is usually installed on the piano cover.

[0003] The damper on the traditional piano cover is a rubber damper, which slows down the closing of the piano cover through the viscosity of the rubber and the friction with the metal. When the rubber is easily aged during long-term use, it is easy to cause damping failure. At the same time, this type of damper is not easy to adjust the damping size, and it is not convenient to control the closing speed of the piano cover as needed. Utility Model Content

[0004] The utility model aims to provide a piano cover buffer structure to solve the problem that the rubber damping is easy to age and difficult to adjust the damping size during long-term use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a piano cover closing buffer structure, comprising a piano body, a closing mechanism connected to the piano body, the closing mechanism comprising a piano cover, the piano body rotatably connected to the piano cover, two sides of the piano body located at the rotating end of the piano cover are connected to slide cylinders, a slide rod is slidably sleeved in the slide cylinder, a piston is installed on the slide rod and is sealed and slidable with the inner wall of the slide cylinder, an air passage communicating with the outside is provided at the bottom end of the slide cylinder, a swing rod is installed at the rotating end of the piano cover, and the swing rod is rotatably connected to the slide rod;

[0006] The slide cylinder is connected to an adjustment mechanism, which includes a stud. The slide cylinder is threadedly connected to the stud at the airway. The bottom end of the stud is rotatably connected to a slide column for cutting off the airway. The slide column is slidably connected to the slide cylinder. The slide column is provided with a plurality of air holes of different diameters, and the two ends of the airway are connected through the air holes.

[0007] As a preferred technical solution of the utility model, the air holes are circular, and a plurality of air holes are arranged in sequence according to size, so as to facilitate the adjustment of air flow, thereby achieving the purpose of controlling the closing speed of the piano cover.

[0008] As a preferred technical solution of the utility model, the slide cylinder and the slide rod are both arc-shaped, the radius of the slide cylinder and the slide rod is the same as the length of the rocker arm, and the center of the slide cylinder and the slide rod is on the axis of the rotation axis of the piano cover, so that the rocker arm can push the slide rod to slide into the interior of the slide cylinder.

[0009] As a preferred technical solution of the utility model, a fixing sleeve is installed on the slide cylinder, and the slide cylinder is locked and fixed on the piano body by the fixing sleeve, so that the slide cylinder can be easily fixed and disassembled.

[0010] As a preferred technical solution of the utility model, the piano cover is in an "L" shape, and a rubber pad is installed at one end of the piano cover that is buckled and abutted against the piano body, thereby playing a certain buffering role when the slide is fixed.

[0011] As a preferred technical solution of the utility model, a closing cover is buckled on the piano body at the slide cylinder, and the closing cover is circular in shape, so as to protect the slide cylinder and the like.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides a swing rod, a slide rod and a slide cylinder. When the piano cover is pushed to close, the piano cover drives the swing rod to rotate, and the swing rod pushes the slide rod to slide inside the slide cylinder. The aperture of the airway is small, so that the gas inside the slide cylinder is slowly discharged from the airway, so that the piano cover slowly rotates and closes under gravity, thereby playing a buffering and protective role for the piano cover and avoiding severe impact on the piano body.

[0014] 2. The utility model provides studs, slides and air holes. When the closing speed of the piano cover is still too fast, the closing cover is removed, and the studs are rotated by a screwdriver, so that the studs move upward, thereby pulling the slides to move, so that the smaller air holes are connected to the airway, thereby reducing the air flow rate, so that when the slide cylinder discharges gas, the gas is discharged more slowly, thereby slowing down the closing speed of the piano cover, and achieving the purpose of controlling the closing speed.

A fixing sleeve 24 is installed on the slide 25, and the slide 25 is locked and fixed on the piano body 1 through the fixing sleeve 24, thereby fixing the slide 25 and facilitating the removal and replacement of the slide 25. The piano cover 21 is in an "L" shape, and a rubber pad 3 is installed at one end of the piano cover 21 that is engaged with the piano body 1, thereby playing a certain buffering role when the slide 25 fails. The piano body 1 is buckled with a closing cover 22 at the slide 25, and the closing cover 22 is circular, thereby protecting the slide 25 and the like to avoid damage due to long-term exposure to the outside.

[0025] During specific use, when the piano cover 21 is pushed to close, the piano cover 21 drives the rocker arm 28 to rotate, and the rocker arm 28 pushes the slide bar 23 to slide inside the slide cylinder 25. The piston 27 plays a sealing role, and the aperture of the airway 26 is small, so that the gas inside the slide cylinder 25 is slowly discharged from the airway 26, so that the piano cover 21 slowly rotates and closes under gravity, thereby playing a buffering and protecting role for the piano cover 21, avoiding severe impact on the piano body 1.
