[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. To provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; these embodiments are only some embodiments of the present invention; other embodiments obtained based on this application without creative effort are all within the scope of protection of the present invention.
[0025] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," etc., are all based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of clearly describing this embodiment. They do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application. At the same time, the terms "first" and "second" in the embodiments are only used for descriptive purposes and do not represent an indication or implication of relative importance.
[0026] like Figure 1 As shown, a specific embodiment of this utility model is a button shaft capable of switching between different striking sounds, including a base 2 and a handle 1 that can move up and down within the base 2. The base 2 serves as the support structure for the entire button shaft, and its interior is provided with space for accommodating components such as the handle 1 and the return spring 3.
[0027] A return spring 3 is provided at the bottom of the handle 1. One end of the return spring 3 abuts against the bottom of the handle 1, and the other end abuts against the base plate 21 inside the base 2. The return spring 3 provides sufficient elastic force after the handle 1 is pressed, so that the handle 1 can be stably reset.
[0028] The bottom of the handle 1 is also provided with a striking protrusion 61, which is used to strike the sound-emitting plate 4 in the slot structure 22 when the handle 1 moves downward, thereby producing sound. The sound-emitting plate 4 should be located below the striking protrusion 61 to ensure that the striking protrusion 61 can strike the sound-emitting plate 4 to produce sound.
[0029] As shown in Figure 6-9, a slot structure 22 is provided inside the base 2, and a sound-generating plate 4 is detachably installed in the slot structure 22. The design of the slot structure 22 allows the user to easily replace the sound-generating plate 4, thereby achieving sound switching. The slot structure 22 should include an open end 221 as the insertion port of the sound-generating plate 4, and limiting ends 222 provided on three sides around the open end 221 to restrict the movement of the sound-generating plate 4 within the slot structure 22. A support part 223 is also provided at the bottom of the slot structure 22 to support the sound-generating plate 4 and prevent it from falling off.
[0030] The base plate 21 is provided with a through hole 23 corresponding to the movement path of the handle 1. When the handle 1 moves downward, the striking protrusion 61 at its bottom can pass through the through hole 23 and strike the sound-emitting plate 4 in the slot structure 22.
[0031] like Figures 2-5 As shown, to further enhance the structural stability of the push handle 1, the present invention also includes a magnetic component 5 and a protective sleeve 6. The upper part of the protective sleeve 6 has a cavity for accommodating the magnetic component 5, and a guide post 11 extends downward from the bottom center of the push handle 1. The guide post 11 can be fitted into the cavity of the protective sleeve 6, encapsulating the magnetic component 5 within the cavity. A striking protrusion 61 is located at the bottom center of the protective sleeve 6. The magnetic component 5 can be used with a Hall element to realize the electromagnetic signal output of the push handle 1. In embodiments of this invention, the magnetic component 5 is not a necessary component and can be selected for installation according to actual needs.
[0032] The protective sleeve 6 has a T-shaped cross-section, with an outwardly extending frustum 62 at its top, which matches the bottom cavity of the handle 1. The upper end of the return spring 3 abuts against the lower part of the frustum 62 to ensure that the return spring 3 can stably provide elastic force.
[0033] The base 2 is provided with a guide cavity that matches the outer diameter of the protective sleeve 6, allowing the protective sleeve 6 to move axially within the guide cavity. The design of the guide cavity limits the range of movement of the protective sleeve 6 and ensures the stability of the button shaft during pressing and resetting.
[0034] The sound-generating plate 4 can be made of copper, iron, aluminum, plastic diaphragm, piezoelectric ceramic, or composite materials. Different sound-generating plates 4 have different vibration characteristics and sound output characteristics, so the sound emitted when the button 1 is pressed can be changed by replacing the sound-generating plate 4.
[0035] When the user presses the handle 1, the handle 1 moves the protective sleeve 6 downwards. The striking protrusion 61 of the protective sleeve 6 passes through the through hole 23 and strikes the sound-emitting plate 4, causing the sound-emitting plate 4 to vibrate and produce sound. When the handle 1 is released, the return spring 3 provides elasticity to return the handle 1 and the protective sleeve 6 to their original positions, and the striking protrusion 61 moves away from the sound-emitting plate 4. The user can change the sound emitted when the handle 1 is pressed by replacing the sound-emitting plate 4 in the slot structure 22.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
