[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a detachable earplug structure for a Bluetooth headset, comprising a Bluetooth headset 1 and an earplug 2, wherein an inner tube 3 is provided inside the earplug 2, and an initial sound pipe is axially provided at the center of the inner tube 3, and the earplug 2 is sleeved on the sound outlet tube 5 of the Bluetooth headset 1 through the inner tube 3, and a slot 11 is axially provided on the outer ring surface of the inner tube 3, and a plug-in plate 4 is provided in the slot 11, one end of the plug-in plate 4 extends to the outside, and is installed with an elastic operating component for driving the plug-in plate 4 to press down, a plurality of positioning holes are provided on the inner wall surface of the slot 11, and plug-in holes are provided on the outer wall surface of the sound outlet tube 5 facing the positioning holes, and positioning columns 6 are installed on the inner side surface of the plug-in plate 4 facing the positioning holes, and the other ends of the positioning columns 6 pass through the positioning holes and are inserted into the plug-in holes.

[0023] In this embodiment, the elastic operating component includes a pull plate 7 and multiple connecting rods 8. The pull plate 7 is arranged on the inner side of the Bluetooth headset 1, and the pull rods are arranged on both sides of the sound outlet tube 5. One end of the pull rods is installed on the side of the plug-in plate 4, and the other end is installed on the pull plate 7. A slider 10 is protruded on the inner side of the pull plate 7. A sliding groove is provided on the outer wall of the Bluetooth headset 1 opposite to the slider 10, and the slider 10 is slidably arranged in the sliding groove.

[0024] In this embodiment, positioning grooves are vertically provided on both sides of the slide groove, and both sides of the slider 10 protrude to form positioning parts, which are slidably set in the positioning grooves. Multiple compression springs 9 are installed between the slider 10 and the slide groove. The slider can be positioned through the positioning groove and the positioning part, thereby preventing the slider from directly detaching from the slide groove.

[0025] In this embodiment, the cross section of the insert plate 4 is arranged in an arc-shaped structure, and the outer ring surface of the insert plate 4 is arranged flush with the outer ring surface of the inner tube 3 to ensure the flatness of the inner tube after installation, thereby avoiding affecting the aesthetics and wearing quality.

[0026] In this embodiment, a plurality of anti-skid grooves are provided on the outer side of the pull plate 7. When the fingers come into contact with the pull plate, the friction between the fingers and the pull plate is increased through the anti-skid grooves.

[0027] In this embodiment, a space for the pull plate 7 to move upward is formed between the pull plate 7 and the sound outlet tube 5, so that the pull plate can move upward smoothly along the slide groove and move the positioning column out of the positioning hole and the slot.

[0029] During installation, the finger can push the pull plate upward along the slide groove. The movement of the pull plate drives the connecting rod and the plug plate until the positioning post on the plug plate is pulled out of the socket and a gap is formed between the plug plate and the sound outlet tube for the inner tube to pass through. After the above is completed, the inner tube of the earplug does not need to be opened and can be directly put on the sound outlet tube. After releasing the pull plate, the rebound of the compression spring can push the slider and the pull plate downward. The movement of the pull plate drives the plug plate and the positioning post, so that the positioning post can pass through the positioning hole on the inner tube and be inserted into the socket again, thereby directly completing the installation and positioning of the earplug. The plug plate can also apply pressure to the inner tube to ensure the stability of the installation.

[0030] On the contrary, after pushing the pull plate upward again, the plug plate can rise again, and the positioning post can be moved out of the socket and the positioning hole. After losing the obstruction of the positioning post, the earplug can be directly removed.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
