[0025] Example

[0026] like Figure 1-5 As shown, the present invention proposes a cockpit with embedded sound insulation cotton, comprising a cockpit body 1, on which a metal back plate 13 and a metal top plate 14 are provided, wherein the metal back plate 13 and the metal top plate 14 are made of iron. The cockpit body 1 also comprises: strip-shaped sound insulation cotton 11 and arc-shaped sound insulation cotton 12 movably mounted in the cockpit body 1 and corresponding to the metal back plate 13 and the metal top plate 14; an installation rod 3 inserted in the strip-shaped sound insulation cotton 11 and the arc-shaped sound insulation cotton 12, wherein one end of the installation rod 3 protruding from the strip-shaped sound insulation cotton 11 and the arc-shaped sound insulation cotton 12 is fixedly connected to a magnetic suction head 2 for sucking the metal back plate 13 and the metal top plate 14, and the magnetic suction head 2 is made of magnetic material, common materials of which include neodymium iron boron, aluminum nickel cobalt or ferrite. These materials have strong magnetism and can effectively absorb iron objects; an anti-loosening mechanism is arranged inside the magnetic head 2 and the mounting rod 3 so that the mounting rod 3 can be manually pressed to prevent the strip sound insulation cotton 11 and the arc sound insulation cotton 12 from falling out.

[0027] Furthermore, the anti-loosening mechanism includes a pair of button rods 21 slidably connected to the magnetic head 2. One end of the button rod 21 inserted into the magnetic head 2 is fixedly connected to a stop block 22. The stop block 22 is used to automatically move the clamping plate 23 toward the installation rod 3 after being pressed. The button rod 21, the stop block 22, and the protruding nail 31 are symmetrically arranged on both sides of the clamping plate 23. The interior of the magnetic head 2 is provided with a clamping plate 23 that moves toward the installation rod 3 after being pressed by the stop block 22. The side of the clamping plate 23 away from the stop block 22 is fixedly connected to a stop rod 24 inserted into the installation rod 3. The interior of the magnetic head 2 is provided with a return spring 26 that is movably connected to the stop rod 24. The return spring 26 is used to enable the clamping plate 23 to drive the stop rod 24 to return to the away position. After that, the stop rod 24 drives the stop head 27 to press against the pair of protruding nails 31, so that the protruding nails 31 are always protruding outside the installation rod 3.

[0028] The anti-loosening mechanism further includes a pair of protruding pins 31 slidably connected to the mounting rod 3. The ends of the protruding pins 31 inserted into the mounting rod 3 are each sleeved with a push spring 33. The push spring 33 ensures that the protruding pins 31 are always retracted into the mounting rod 3 when not abutted by the abutment 27. One end of the push spring 33 is fixedly connected to a snap ring 32, and the other end of the push spring 33 is fixedly connected to the inner wall of the mounting rod 3. The ends of the protruding pins 31 closest to the abutment 27 are each fixedly sleeved with a snap ring 32 to prevent the protruding pins 31 from falling out of the mounting rod 3. The end of the abutment rod 24 away from the clamping plate 23 is fixedly connected to the abutment 27 that abuts the protruding pin 31. The end of the abutment rod 24 closest to the abutment 27 is provided with a slot 25 for retracting the protruding pin 31 into the mounting rod 3.

[0029] Furthermore, one end of the installation rod 3 that is away from the magnetic head 2 and inserted into the strip sound insulation cotton 11 and the arc sound insulation cotton 12 is provided with a conical tip 34. The function of the conical tip 34 is to make it easier to insert the installation rod 3 into the strip sound insulation cotton 11 and the arc sound insulation cotton 12.

[0030] In this embodiment, when a cockpit with built-in sound insulation cotton is required, Figure 2 To retract, simply remove the multiple strips of sound insulation 11 and arcs of sound insulation 12 from the outer walls of the metal backplate 13 and metal top plate 14. The magnetic head 2, which attracts the metal backplate 13 and metal top plate 14, allows for quick assembly and disassembly of the strips of sound insulation 11 and arcs of sound insulation 12. During this process, no toxic gases are generated that could harm the driver's health in the cockpit, and no difficult-to-dispose residue is left after disassembly. To recycle the mounting rod 3 and magnetic head 2 inserted into the strips of sound insulation 11 and arcs of sound insulation 12, simply push the button rod 21 into the magnetic head 2. The end of the button rod 21 inserted into the magnetic head 2 will drive the block 22 to press against the latch plate 23 inside the magnetic head 2. The latch plate 23, in turn, drives the rod 24, the slot 25, and the head 27 to move until the rod 24 drives the slot 25 to the position of the protruding pin 31. At this point, the snap ring 32, through the elastic thrust of the push spring 33, drives the protruding pin 31 into the corresponding retaining groove 25. When the protruding pin 31 is fully retracted into the mounting rod 3, the magnetic head 2 is pulled out of the strip-shaped sound insulation cotton 11 and the arc-shaped sound insulation cotton 12. The magnetic head 2 now drives the mounting rod 3 to be easily removed from the strip-shaped sound insulation cotton 11 and the arc-shaped sound insulation cotton 12. Conversely, to insert the mounting rod 3 into the strip-shaped sound insulation cotton 11 and the arc-shaped sound insulation cotton 12, simply reverse the above steps, which will not be repeated here.
