Description

Technical Field

[0001] This utility model relates to the field of headphone plastic parts equipment, specifically a high-strength two-color headphone plastic part. Background Technology

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. During headphone manufacturing, plastic parts need to be assembled and fixed. However, the small contact area of ​​existing headphone plastic parts makes it impossible to provide high-strength drop protection.

[0003] According to a patent document with publication number CN116489563B, a Bluetooth headset includes a charging case, a protective cover, a fixing structure, and a fixing block. The charging case is rotatably connected to the protective cover. The fixing structure includes a fixing block slidably connected to the charging case, and the protective cover has a fixing groove that matches the fixing block. In use, the fixing block and the protective cover engage to prevent the protective cover from opening and the Bluetooth headset from falling out when the charging case is dropped on the ground, thus preventing damage to the Bluetooth headset. However, while this solution effectively prevents damage to the headset, it does not increase the contact area between the plastic parts of the headset and does not allow for quick disassembly of the headset, which is inconvenient during use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength dual-color earphone plastic part to solve the problems mentioned in the background technology. The utility model has a novel structure. When in use, the movable seat moves upward first, the arc block separates from the arc groove, the movable seat loses its fixed point, and the movable seat drives the threaded column to rotate from the inside of the fixed seat, which facilitates quick disassembly and maintenance.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-strength dual-color earphone plastic part, including a fixed base, a limiting seat fixedly installed on the side of the fixed base, a ring seat fixed on the top of the fixed base, an arc-shaped groove on the ring seat, an arc-shaped block movably installed inside the arc-shaped groove, a movable seat fixed on the arc-shaped block, a movable disk and a convex disk respectively installed on the movable seat, a cavity on the movable seat, the movable disk being movably installed inside the cavity through a reset mechanism, and an annular groove on the inner wall of the cavity.

[0006] Furthermore, a connecting seat is fixed to the bottom of the fixed base, and an earplug is movably mounted on the connecting seat.

[0007] Furthermore, the movable seat has a fixing groove inside, and a threaded column is movably installed inside the fixing groove.

[0008] Furthermore, the threaded column has a groove, and a slider is movably installed inside the groove, with one end of the slider fixed to the movable seat.

[0009] Furthermore, a support mechanism is fixed between the slider and the groove, and a horn is fixedly installed at one end of the threaded column.

[0010] Furthermore, a retaining ring is fixed on the convex disc, the retaining ring being movably installed inside the annular groove, and the convex disc being movably installed inside the cavity.

[0011] The beneficial effects of this utility model are:

[0012] 1. This high-strength dual-color earphone plastic part, when in use, the movable seat moves upward first, the arc-shaped block separates from the arc-shaped groove, the movable seat loses its fixed point, and the movable seat drives the threaded column to rotate from the inside of the fixed seat, which facilitates quick disassembly and maintenance.

[0013] 2. In this high-strength dual-color earphone plastic part, after the threaded post is rotatably installed inside the fixed seat, the threaded post increases the support area inside the fixed seat, thereby achieving a high-strength reinforced connection between the fixed seat and the movable seat.

[0014] 3. This high-strength dual-color earphone plastic part allows the convex discs on the left and right earphones to be movably installed inside the cavity. The retaining ring and the ring groove cooperate to achieve limiting and fixing, thereby achieving a fixed connection between the two earphones through the cooperation of the convex discs and the cavity. The combination of the earphones increases its volume, making it easier to carry and move later, and also easier to find later. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a high-strength dual-color earphone plastic part, including a fixed base 1, a limiting seat 2 fixedly installed on the side of the fixed base 1, a ring seat 3 fixedly fixed on the top of the fixed base 1, an arc-shaped groove 4 opened on the ring seat 3, an arc-shaped block 5 movably installed inside the arc-shaped groove 4, a movable seat 6 fixed on the arc-shaped block 5, a movable disk 7 and a convex disk 19 respectively installed on the movable seat 6, a cavity 12 opened on the movable seat 6, the movable disk 7 movably installed inside the cavity 12 through a reset mechanism 18, an annular groove 13 opened on the inner wall of the cavity 12, a connecting seat 8 fixedly fixed on the bottom of the fixed base 1, an earplug 9 movably installed on the connecting seat 8, the arc-shaped block 5 and the arc-shaped groove 4 cooperate to provide a support point for the movable seat 6, thereby preventing the movable seat 6 from rotating and causing accidental opening between parts.

[0022] In this embodiment, the movable seat 6 has a fixed groove 14 inside, and a threaded post 10 is movably installed inside the fixed groove 14. A sliding groove 15 is opened on the threaded post 10, and a slider 16 is movably installed inside the sliding groove 15. One end of the slider 16 is fixed to the movable seat 6, and a support mechanism 17 is fixed between the slider 16 and the sliding groove 15. A horn 11 is fixedly installed at one end of the threaded post 10. A retaining ring 20 is fixed on the convex plate 19, and the retaining ring 20 is movably installed inside the annular groove 13. The convex plate 19 is movably installed inside the cavity 12. Both the support mechanism 17 and the reset mechanism 18 are springs. After the movable plate 7 loses its compressive force, the reset mechanism 18 pushes the movable plate 7 back to its original position to seal and block the cavity 12.

[0023] When internal parts need to be repaired, the movable seat 6 is moved upwards. As the movable seat 6 moves upwards, the slider 16 moves inside the slide groove 15, pressing against the support mechanism 17. The slider 16 and the slide groove 15 cooperate to provide vertical movement space for the movable seat 6 to rise. After the movable seat 6 moves upwards, the arc-shaped block 5 and the arc-shaped groove 4 separate. After separation, the movable seat 6 drives the threaded column 10 to rotate. The threaded column 10 rotates and is removed from inside the fixed seat 1. After the threaded column 10 is removed, the horn 11 is also removed simultaneously. The horn 11 and the integrated circuit board are both mounted on the movable seat 6. Disassembling the movable seat 6 facilitates the repair of internal electronic components. Later, the threaded column 10... During installation, the threaded post 10 rotates and is installed inside the fixed base 1, providing support for the interior of the fixed base 1. Under the support of the threaded post 10, a high-strength fixing force is provided for the fixed base 1 and the movable base 6, thereby effectively preventing breakage between the fixed base 1 and the movable base 6 due to collision. When not in use, the convex plate 19 on the left and right earphones is installed at the position of the movable plate 7. The convex plate 19 presses against the movable plate 7, and the movable plate 7 retracts into the cavity 12 under the pressure. With one end of the convex plate 19, the retaining ring 20 enters into the annular groove 13 to achieve limiting and fixing. The retaining ring 20 and the annular groove 13 cooperate to realize the connection and combination between the two earphones, which is convenient for later carrying and quick retrieval.
