[0021] The device for preventing objects from falling into the gap of a horizontal piano keyboard cover of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] Combined with Figure 1-9The invention discloses a device for preventing objects from falling through the gap of a horizontal piano keyboard cover, comprising a fixed plate 1 and a baffle plate 2; the fixed plate 1 is rotatably connected to the baffle plate 2, a connecting hole 3 is provided on the fixed plate 1, a slider 5 is fixedly connected to the end of the baffle plate 2 away from the fixed plate 1, and springs 6 are symmetrically provided at the two ends of the baffle plate 2 adjacent to the fixed plate 1; the device for preventing objects from falling through the gap of a piano keyboard cover comprises a guide plate 7, a slide groove 4 cooperating with the slider 5 is provided on one side of the guide plate 7; one end of the spring 6 is connected to the baffle plate 2, and the other end of the spring 6 is connected to the support plates on both sides of the piano keyboard; the guide plate 7 is installed on the ceiling inside the piano.

[0023] There are four connecting holes 3 in total, and the four connecting holes 3 are arranged in pairs along the middle of the fixing plate 1 symmetrically to both sides.

[0024] There are two sliders 5 in total, and the two sliders 5 are arranged at two vertex corners of the baffle plate 2 away from the fixed plate 1 . There are two guide plates 7 in total, and they are used to cooperate with the two sliders 5 .

[0025] The slider 5 is a metal ball.

[0026] The fixing plate 1 is connected to the rear half of the bottom of the piano keyboard cover by bolts.

[0027] The inner wall of the slide groove 4 is coated with lubricating material.

[0028] When the present invention is implemented, the installation position of the fixed plate 1 is at the rear half of the bottom of the piano cover, and the width is slightly shorter than the rear half. In this way, the baffle plate 2 connected from the slightly shorter position can form an angle with the opened piano cover, and the objects dropped in can be just caught by using this angle. When the piano cover is in the open state, the angle is in a static state of about 45°. The action of the spring 6 allows the baffle plate 2 to have an upward force so that it will not fall down. When the piano cover is in the process of closing, the piano cover rotates around the axis, and the fixed plate 1 and the baffle plate 2 will be lifted accordingly. When it is closed to a certain extent, the slider 5 on the baffle plate 2 will touch the guide plate 7 set on the ceiling inside the piano, allowing the slider 5 to slide back and forth along the slide groove 4. At the same time, the baffle plate 2 changes its angle, and the objects dropped in at this time will also slide out with the change of the angle of the baffle plate 2. The piano cover continues to close until it is completely closed, and the baffle plate 2 forms a very small angle with the bottom of the string axis plate, and the gap of the piano cover is closed.

[0029] The present invention stops objects falling into the gap of the piano keyboard cover by using the blocking plate. When the keyboard cover is closed, the objects slide out from the gap of the keyboard cover due to gravity, thereby solving the problem of objects falling out of the gap of the keyboard cover. The present invention does not make a major change to the shape of the piano, does not affect the normal use and performance of the piano, is easy to install, and has good practicality.

[0030] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
