[0026] Reference Figure 1As shown, the utility model provides a technical solution: a CD player for audio playback, comprising a player body 1, a protective device 2 is provided on the upper surface of the player body 1, and the protective device 2 is provided to achieve the effect of dustproofing the control buttons on the surface of the player body 1, thereby preventing dust from covering the surface of the player body 1 when the player body 1 is stored or idle for a long time, causing a large amount of dust to enter the gaps between the control buttons of the player body 1, causing the control buttons of the player body 1 to malfunction, thereby improving the protection of the device, and a wire clamping device 3 is provided on the surface of the player body 1, and the wire clamping device 3 is provided to achieve the effect of clamping the connecting wire connected to the player body 1, thereby preventing the player body 1 from being displaced by the force generated by the collision when the player body 1 is hit by an external force, causing the connection between the player body 1 and the connecting wire to be forcibly disconnected, thereby causing the playback to be interrupted, thereby improving the practicality of the device.

[0027] The specific settings and functions of the protective device 2 and the wire clamping device 3 are described in detail below.

[0028] Reference Figure 2 and Figure 3As shown, in this embodiment: the protective device 2 includes a connecting plate 201, the connecting plate 201 is fixedly connected to the upper surface of the player body 1, and strip plates 202 are fixedly connected to both sides of the connecting plate 201. The side of the two strip plates 202 close to each other is fixedly connected to a rotating rod 203, and the circular arc surface of the rotating rod 203 is rotatably connected to a rotating plate 204. The side of the rotating plate 204 close to the player body 1 is fixedly connected to a protective compartment 205, and the protective compartment 205 is slidably connected to the surface of the player body 1. A fixed rod 206 is fixedly connected to one side of the player body 1, and the circular arc surface of the fixed rod 206 slides. The protective compartment 205 is provided with a plug 208 on one side of the protective compartment 205 near the operating panel 207, and a jack is provided on the side of the protective compartment 205 near the operating panel 207. The end of the fixed rod 206 away from the player body 1 is fixedly connected to a limiting plate 209. The size of the plug 208 matches the size of the jack of the protective compartment 205. When the staff pulls the operating panel 207, the operating panel 207 slides on the arc surface of the fixed rod 206. At this time, the limiting plate 209 achieves the effect of limiting the maximum sliding distance of the operating panel 207 on the fixed rod 206, thereby preventing the staff from pulling the operating panel 207. When the operating plate 207 is released, due to excessive pulling force, the operating plate 207 is separated from the arc surface of the fixing rod 206. The arc surface of the fixing rod 206 is sleeved with a first spring 210, and the two ends of the first spring 210 are respectively fixedly connected to the operating plate 207 and the player body 1. When the staff releases the operating plate 207, the rebound force of the first spring 210 drives the operating plate 207 to slide on the arc surface of the fixing rod 206. At the same time, the operating plate 207 drives the insertion rod 208 to move until the insertion rod 208 is inserted into the insertion hole of the protection compartment 205. At this time, the first spring 210 increases the insertion rod 208 to the protection compartment 205. In order to ensure the stability of the protective bin 205 when it is limited, the arc surface of the rotating rod 203 is covered with two torsion springs 211, and the two ends of the torsion spring 211 are fixedly connected to the strip plate 202 and the rotating plate 204 respectively. When the staff releases the limit of the protective bin 205 by the insertion rod 208, the torsion force of the torsion spring 211 drives the rotating plate 204 to rotate on the arc surface of the rotating rod 203. At the same time, the rotating plate 204 drives the protective bin 205 to move until the protective bin 205 is fully opened. At this time, the effect of automatically opening the protective bin 205 is achieved, so as to reduce the staff's operating steps for the device and improve the staff's work efficiency.

[0029] Reference Figure 2 and Figure 4As shown, specifically, the clamping device 3 includes a fixing plate 301, the fixing plate 301 is fixedly connected to the surface of the player body 1, the fixing plate 301 is internally threaded with a driving rod 302, one end of the driving rod 302 is rotatably connected to a clamping plate 303, a side of the player body 1 close to the fixing plate 301 is fixedly connected to an abutment plate 304, an end of the driving rod 302 away from the clamping plate 303 is fixedly connected to a handle 305, and a side of the clamping plate 303 close to the driving rod 302 is fixedly connected to a positioning rod 306, and the arc surface of the positioning rod 306 It is slidably connected to the fixed plate 301. When the staff turns the handle 305, the handle 305 drives the driving rod 302 to move in the inner thread of the fixed plate 301. At the same time, the driving rod 302 drives the clamping plate 303 to move, and the clamping plate 303 drives the positioning rod 306 to slide in the fixed plate 301. At this time, the positioning rod 306 has the effect of limiting the clamping plate 303 from following the rotation of the driving rod 302, thereby avoiding the clamping plate 303 from following the rotation of the driving rod 302, causing the position of the clamping plate 303 to be offset, thereby affecting the clamping effect.

[0030] Working principle: when the staff needs to protect the control buttons on the player body 1, pull the operating panel 207 to make the operating panel 207 slide on the arc surface of the fixed rod 206, and the first spring 210 is pulled. At this time, the operating panel 207 drives the insertion rod 208 to move until the insertion rod 208 no longer blocks the movement of the protection compartment 205. At this time, press the protection compartment 205, and the protection compartment 205 drives the rotating plate 204 to rotate on the arc surface of the rotating rod 203 until the protection compartment 205 covers the control buttons on the player body 1. At this time, release the operating panel 207. The rebound force of the first spring 210 drives the operating panel 207 to slide on the arc surface of the fixing rod 206, and at the same time, the operating panel 207 drives the insertion rod 208 to move until the insertion rod 208 is inserted into the insertion hole of the protective compartment 205. At this time, the control buttons on the surface of the player body 1 are dust-proof, which avoids dust covering the surface of the player body 1 when the player body 1 is stored or idle for a long time, causing a large amount of dust to enter the gaps of the control buttons of the player body 1, causing the control buttons of the player body 1 to malfunction, thereby improving the protection of the device.

[0031] When the staff needs to clamp the connecting wire connected to the player body 1, they turn the handle 305, and the handle 305 drives the driving rod 302 to move in the inner thread of the fixing plate 301. At the same time, the driving rod 302 drives the clamping plate 303 to move, and the clamping plate 303 drives the positioning rod 306 to slide in the fixing plate 301 until the clamping plate 303 abuts against the connecting wire of the player body 1, and at the same time, the connecting wire of the player body 1 abuts against the abutment plate 304. At this time, the connecting wire connected to the player body 1 is clamped, and the force generated by the collision when the player body 1 is hit by an external force causes the player body 1 to be displaced, resulting in the forced disconnection of the connection between the player body 1 and the connecting wire, thereby causing the playback to be interrupted, thereby improving the practicability of the device.
