A silent foot switch and its application

Abstract

The present invention discloses a silent foot switch, which includes a bushing, a main spindle, a swing spindle, a spindle spring, a switch spring, a first rubber ring and a second rubber ring. The present invention also discloses an application of the silent foot switch. The overall structure of the silent foot switch is compact and complete. By adding the first rubber ring and the second rubber ring to the collision structure, the frictional sound generated during movement is reduced, so as to achieve the effect of eliminating noise and forming a silent effect, meeting the silent needs of most users. At the same time, a relatively viscous damping oil can be coated on the scraping position of the inner wall of the bushing to enhance the sound elimination effect, and the whole can be applied to electronic musical instruments and electrical appliances that need to remain relatively quiet in structure during operation, removing noise and meeting the requirements of instrument users for sound quality.

[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation modes.

[0029] As Figures 1 to 9 shown, in this embodiment, a silent foot switch includes a bush 1, a main spindle 2, a swing axis 3, an axis spring 4, a switch spring 5, a first rubber ring 6 and a second rubber ring 7. The main spindle 2 is inserted into the bush 1. The first rubber ring 6 is sleeved on the upper end of the outer side of the bush 1. The second rubber ring 7 is located inside the bush 1. The upper end of the second rubber ring 7 is attached to the upper end of the inner side of the bush 1. The lower end of the second rubber ring 7 is attached to the lower end of the outer side of the main spindle 2. The swing axis 3 includes an upper axis part, a middle axis part and a lower axis part. The upper axis part abuts against the upper end of the inner side of the main spindle 2. The upper end of the axis spring 4 is connected to the upper axis part. The lower end of the axis spring 4 is connected to the lower end of the bush 1. The upper end of the switch spring 5 is connected to the lower axis part.

[0030] Specifically, the radial dimension of the upper axis part is greater than the radial dimension of the middle axis part. The radial dimension of the middle axis part is greater than the radial dimension of the lower axis part. A torsion cap 8 is connected to the upper end of the main spindle 2. Moreover, the torsion cap 8 is bolted to the main spindle 2. A stop ring 9 is connected to the lower end of the bush 1. The stop ring 9 is threadedly connected to the bush 1. The lower end of the axis spring 4 is connected to the stop ring 9. A connecting thread is provided on the outer side of the bush 1.

[0031] This silent foot switch can form the first product as Figures 1 - 3 shown, the second product as Figures 4 - 6 shown, and the third product as Figures 7 - 9For the third product shown, when in use, the user presses the knob cap 8, and the knob cap 8 will push the main spindle 2 downward to move. When the main spindle 2 moves along the inner wall of the bushing 1, the swing spindle 3 is pressed by the main spindle 2 to move downward, and the switch spring 5 is pressed to trigger the microswitch of the components on the musical instrument to control the entire musical instrument system. During the movement of the main spindle 2, the first rubber ring 6 and the second rubber ring 7 are relied on to reduce the noise caused by friction between structures. Moreover, when in use as a whole, a relatively viscous damping oil can also be applied to the inside of the bushing 1 to further enhance the effect of eliminating noise. In addition, the spindle spring 4 in the structure restores the main spindle 2 to its original position after the knob cap 8 is released.

[0032] It should be noted that the above specific embodiments are only the preferred embodiments of the present invention and the technical principles applied. Any changes or substitutions that are easily conceivable by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
