Technical Field
The utility model belongs to the technical field of airflow control structures, and particularly relates to a tray sealing structure for controlling airflow of a pipe organ, which is a structure for controlling sounding switch and duration of a sound pipe of the pipe organ and reducing control noise.
Background
In a tube organ, the tray is a very important component. It is a device for storing air, which can help to blow the sound tube and transmit notes of different pitches to the components of the keyboard. The tray can be traced to an ancient mechanical organ. In these organs, a rotating fan generates wind and is fed through a pipe into a hand bellows, which then adjusts the pitch through a whistle. In mechanical accordion, the sounds made by the various notes are controlled by bellows and whistle. Over time, the structure and tone quality of the organ is improved. In modern organ pipes, each sound tube is connected to an air storage area, which can store compressed air. The tray is the part that connects the sound tube to this area. In the organ, the tray is usually made of wood or metal, has sealing properties, and is equipped with a movable valve, which allows to control the air flow. When the player presses the keyboard, the valve opens, and compressed air flows through the sound tube of the organ, thereby producing musical sound. When the keyboard is released, the valve closes and the mesh stops because the mesh requires a continuous flow of air to be maintained. In general, trays relate to a number of fields of aeromechanics, materials science, mechanical engineering, etc. The excellent tray is made to be important to the tone quality and performance of the organ.
In the conventional organ tray control structure, as shown in fig. 6, the pressure between the tray and the laminate is mainly provided by means of torsion springs, and the conventional control structure has large volume and low space utilization efficiency. Therefore, there is a need in the industry for a tray control structure that has more excellent performance.

the tray mounting shafts 5 are arranged on the lower surface of the base plate 6, one ends of all trays 1 are arranged on the tray mounting shafts 5 through mounting holes, all trays 1 can rotate around the tray mounting shafts 5, the contact part of the end parts and the lower surface of the base plate 6 is in a sealing mode, and air cannot circulate;
the screw 3 is used for limiting the tray 1 on the lower surface of the base plate 6 through a U-shaped opening structure at the other end of the tray 1, the screw 3 is in threaded connection with the base plate 6, and the spring 2 is sleeved on the screw 3;
the middle part of the tray 1 is also provided with a through hole in the vertical direction; the traction device 4 is a connecting rod, the top end of the connecting rod is fixedly connected with the lower surface of the corresponding key, and the bottom end of the connecting rod passes through the through hole on the base plate 6 and the through hole on the tray 1 and is fixed on the tray 1.
The spring 2 is matched with the traction device 4 together to play a role in resetting and opening the tray 1.
The utility model has the beneficial effects that: the utility model provides restoring force by replacing the torsion spring with the small volume of the spring, thereby reducing the volume required by the tray, reducing the space required by the structure and lowering the cost. The utility model has simple and reliable structure and great popularization and application value.

Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings and technical schemes.
A tray sealing structure for controlling air flow of a pipe organ according to the embodiment of the utility model is shown in fig. 1, and comprises a tray 1, a spring 2, a screw 3, a traction device 4, a tray mounting shaft 5 and a base plate 6.
The base plate 6 is symmetrically provided with a plurality of strip-shaped through holes for air circulation; the trays 1 are arranged one by one in each through hole on the base plate 6 and cover the through holes.
The tray 1, its one end is equipped with horizontal mounting hole, and the other end is convex U type open structure, and the middle part still is equipped with a through-hole of vertical direction.
The tray installation shaft 5 is supported at the lower surface of the base plate 6 at two ends, and is movable or fixed, one ends of all trays 1 are installed on the tray installation shaft 5 through installation holes, all trays 1 can rotate around the tray installation shaft 5, and the tray installation shaft 5 plays a role in fixedly supporting all trays 1.
The screw 3 is positioned in a U-shaped opening structure at the other end of the tray 1 and is in threaded connection with the base plate 6.
The tray mounting shaft 5 and the screw 3 jointly play a limiting role.
The spring 2 is sleeved on the screw 3.
