DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the embodiments:

[0026] like Figure 1-5 As shown, the utility model provides a foldable Bluetooth headset, including an earphone shell 1, an adjusting mechanism 2 is installed on the top of the earphone shell 1, an earphone receiver 3 is installed on the bottom of the adjusting mechanism 2, a limiting mechanism 4 is installed on the rear end of the earphone shell 1, the adjusting mechanism 2 includes a receiving groove 21, the receiving groove 21 is opened inside the top end of the earphone shell 1, the inside of the receiving groove 21 is rotatably connected with a rotating shaft 22, a mounting seat 23 is installed outside the rotating shaft 22, the right end of the earphone shell 1 is rotatably connected with a knob 24, and a limiting groove 25 is opened on the top of the mounting seat 23.

[0027] The bottom end of the mounting base 23 is fixedly connected to the rear end of the earphone receiver 3 .

[0028] A set of limiting grooves 25 are also formed on the lower side of the mounting seat 23 . The limiting grooves 25 are engaged with the limiting blocks 45 and are movably mounted.

[0029] By adjusting the mechanism 2 and utilizing the knob 24, the shaft 22 can drive the mounting base 23 to rotate 90 degrees, thereby causing the mounting base 23 to drive the earphone receiver 3 to rotate synchronously, thereby facilitating the earphone receiver 3 to be stored in the receiving slot 21 or rotated out of the receiving slot 21, thereby facilitating the earphone receiver 3 to be folded for use, thereby preventing the earphone receiver 3 from being squeezed out or the ear cap from being squeezed out and lost when squeezed too much, thereby improving its applicability.

[0030] like Figure 4 As shown, the outside of the rotating shaft 22 is fixedly connected to the inside of the mounting seat 23 .

[0031] A receiving groove 21 extends from the top of the rotating shaft 22 and is fixedly connected to the rear end of the knob 24 .

[0032] Limiting grooves 25 of the same size are provided on the top and the bottom of the mounting seat 23 , so that the earphone receiver 3 can be conveniently fixed in position by the limiting block 45 when it is located in the receiving groove 21 or outside the receiving groove 21 .

[0033] like Figure 5 As shown, the limiting mechanism 4 includes a slot 41, a slot 41 is provided inside the rear end of the earphone shell 1, guide slots 42 are symmetrically provided on the front and rear inner walls of the slot 41, a slide plate 43 is slidably connected inside the slot 41, guide blocks 44 are symmetrically fixedly installed on the front and rear sides of the slide plate 43, a limiting block 45 is fixedly installed on the left end of the slide plate 43, a pull rod 46 is fixedly installed in the middle of the right end of the slide plate 43, a pull handle 47 is installed on the top of the pull rod 46, springs 48 are symmetrically fixedly installed on both sides of the right end of the slide plate 43, and a through hole 49 is provided on the inner wall of the left end of the slot 41.

[0034] The guide groove 42 matches the guide block 44 and is slidably connected. The empty groove 41 is connected to the receiving groove 21 through the through hole 49. The limit block 45 penetrates and is movably connected to the through hole 49.

[0035] The top of the spring 48 is fixedly connected to the inner wall of the right end of the empty slot 41 , the top of the pull rod 46 extends out of the empty slot 41 , and the top of the pull rod 46 is fixedly installed to the rear end of the pull handle 47 .

[0036] When the slide plate 43 slides in the empty groove 41 , the guide block 44 is driven to slide synchronously in the guide groove 42 , thereby improving the stability of the movement of the slide plate 43 .

[0037] The following is a detailed description of the working principle of the foldable Bluetooth headset.

[0038] like Figure 1-5As shown, when the foldable Bluetooth headset is in use, when the headset is finished, the earphone receiver 3 needs to be folded. First, the user can pull the handle 47 backwards, so that the handle 47 drives the pull rod 46 to move synchronously, so that the pull rod 46 drives the slide plate 43 to slide backwards in the empty slot 41, so that the spring 48 is squeezed, and at the same time the slide plate 43 drives the limit block 45 to move synchronously, so that the limit block 45 is separated from the limit slot 25 at the top of the mounting seat 23, and then the user can turn the knob 24, so that the knob 24 drives the shaft 22 to rotate, so that the shaft 22 drives the fixed sleeve mounting seat 23 to move synchronously, so that the mounting seat 23 rotates downward 90 degrees, and at the same time the mounting seat 23 can drive the earphone receiver 3 to rotate synchronously. The earphone receiver 3 is rotated step by step, so that the earphone receiver 3 is rotated and stored in the accommodating groove 21, thereby completing the folding operation. At the same time, the limiting groove 25 opened on the lower side of the mounting seat 23 is consistent with the position of the through hole 49. At the same time, the user can loosen the pull handle 47, and under the elastic action of the deformed spring 48, the slide plate 43 will be squeezed to move toward the mounting seat 23, so that the slide plate 43 drives the limiting block 45 to move synchronously, so that the limiting block 45 passes through the through hole 49 and is inserted into the limiting groove 25 on the lower side of the mounting seat 23, and then the mounting seat 23 can be limited and fixed, so that it can protect the earphone receiver 3 and allow it to be placed, so as to avoid the earphone receiver 3 being squeezed out or the ear cap being squeezed out and lost when it is squeezed too much.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
