DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0023] Embodiment 1: An ear-protective adjustable Bluetooth speaker, such as Figure 1-Figure 8 As shown, it includes a guide rail 1, a sliding frame Ⅰ2, a sliding block 3, a limiting block 4, a sliding frame Ⅱ5, a speaker 7, a connecting shaft 8 and a protective pad 9. The left and right parts of the guide rail 1 are slidably connected with the sliding block 3, the sliding block 3 is fixedly connected with the sliding frame Ⅰ2, the front and rear parts of the lower part of the sliding frame Ⅰ2 are fixedly connected with the limiting block 4, the sliding frame Ⅰ2 is slidably connected with the sliding frame Ⅱ5, the front and rear parts of the inner side of the sliding frame Ⅱ5 are opened with sliding grooves 6, the limiting block 4 is located in the sliding groove 6, the lower part of the sliding frame Ⅱ5 is rotatably connected with a front-and-rear symmetrical connecting shaft 8, the speaker 7 is fixedly connected between the front and rear connecting shafts 8, the inner side of the speaker 7 is covered with a protective pad 9, and the protective pad 9 is made of sponge material to reduce discomfort.

[0024] When using the device, the staff can control the sliding block 3 to slide in the guide rail 1, thereby driving the sliding frame Ⅰ2, the sliding frame Ⅱ5 and the speaker 7 to move left and right to adjust the width. Under the cooperation of the limit block 4 and the sliding groove 6, the sliding frame Ⅱ5 can be controlled to slide up and down on the sliding frame Ⅰ2 to adjust the height position of the speaker 7. When the speaker 7 fits the ear, the protective pad 9 can improve the comfort. At the same time, under the action of the rotating connection between the connecting shaft 8 and the sliding frame Ⅱ5, the speaker 7 can be rotated to adjust the angle to avoid squeezing the ears of the staff and causing discomfort. In this way, multi-directional adjustments can be performed to improve the comfort of using the device.

[0025] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Figure 3As shown, it also includes a support block 10, a bidirectional screw 11 and a rotating ring 12. The left and right parts of the upper side of the guide rail 1 are fixedly connected to the support block 10, and the bidirectional screw 11 is rotatably connected between the left and right support blocks 10. The sliding block 3 is connected to the bidirectional screw 11 through a threaded connection, and the left and right parts of the bidirectional screw 11 are fixedly connected to the rotating ring 12. The rotating ring 12 is provided with circumferentially equidistantly distributed grooves for anti-slip.

[0026] When adjusting the distance between the left and right speakers 7, the staff drives the bidirectional screw 11 to rotate by rotating the ring 12. The rotation of the bidirectional screw 11 drives the sliding block 3 to move toward or away from each other, thereby adjusting the distance between the two speakers 7 to adapt to users with different head sizes.

[0027] like Figure 1 As shown, a protective shell 13 is also included. The upper side of the guide rail 1 is fixedly connected to the protective shell 13, and the bidirectional screw 11 is rotatably connected to the protective shell 13.

[0028] When the device is used, the protective shell 13 can shield the bidirectional screw 11 and the sliding block 3, thereby improving the appearance of the device and preventing foreign matter from getting stuck in the bidirectional screw 11 and the sliding block 3.

[0029] like Figure 1-Figure 8 As shown, it also includes a guide shell 14, a fixed rod 15, a piston cylinder 16, a piston rod 17, a push rod 18, a clamping rod 19 and a return spring 20. The guide shell 14 is fixedly connected to the sliding frame Ⅰ2, and the fixed rod 15 is fixedly connected to the sliding frame Ⅰ2. The upper and lower parts of the fixed rod 15 are fixedly connected to the piston cylinder 16. The piston cylinder 16 has two cavities. The piston rod 17 is slidably connected to the upper cavity of the piston cylinder 16, and the push rod 18 is slidably connected to the lower cavity of the piston cylinder 16. The inner side of the push rod 18 is fixedly connected with an equidistantly distributed clamping rod 19, and a return spring 20 is connected between the front and rear push rods 18. The front and rear sides of the sliding frame Ⅱ5 are provided with equidistantly distributed clamping grooves 21, and the clamping rod 19 penetrates the sliding frame Ⅰ2 and is clamped into the clamping groove 21.

[0030] When it is necessary to adjust the height position of the left and right speakers 7, the staff pushes the piston rod 17 to slide inward. The inward sliding of the piston rod 17 squeezes the push rod 18 through the air to slide outward, the return spring 20 is deformed, and the push rod 18 slides outward, driving the clamping rod 19 to move outward and no longer get stuck in the clamping slot 21. At this time, the sliding frame Ⅱ5 can slide up and down to adjust the height position of the speakers 7. After the adjustment is completed, the staff releases the piston rod 17. Under the action of the return spring 20 resetting, the push rod 18 drives the clamping rod 19 to move inward and get back into the clamping slot 21, thereby fixing the position of the sliding frame Ⅱ5.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
