Referring to fig. 1 to 7, a housing structure of a radio cassette player includes a housing 100 and a mounting ring 200;

the cross section of the mounting ring piece 200 is in a square ring shape, the inner walls of two sides of the mounting ring piece 200 are respectively provided with a blocking mechanism 300, each blocking mechanism 300 comprises an electromagnet 301, a spring 302 and a blocking block 303, one end of the spring 302 is connected to the electromagnet 301, and the other end of the spring 302 is connected to the blocking block 303;

the shell 100 is matched with the inner ring of the mounting ring piece 200 in size, the shell 100 penetrates through the mounting ring piece 200, the mounting clamping pieces 400 are arranged on the side walls of the two sides of the shell 100 corresponding to the positions of the blocking blocks 303, each mounting clamping piece 400 comprises an elastic piece 401 and a blocking plate 402, one end of each elastic piece 401 is fixed on the shell 100, the other end of each elastic piece is provided with the blocking plate 402, each elastic piece 401 and the side wall of the shell 100 form an included angle, the extension line of each elastic piece 401 is parallel to the top surface 101 of the shell 100, the included angle formed by each elastic piece 401 and the side wall of the shell 100 is right opposite to the front surface 102 of the shell 100, the electromagnet 301 is powered off, and when the blocking plate 402 on each elastic piece 401 is positioned behind the corresponding blocking block 303, the.

Referring to fig. 3 and 5, the housing 100 is mounted on the vehicle body 500 through a mounting ring 200, the mounting ring 200 is fixed in a mounting groove 501 on the vehicle body 500, mounting screw holes 201 are provided on both sides of the mounting ring 200, and the mounting ring 200 is fixed in the mounting groove 501 through screws.

Referring to fig. 1 and 6, the top surface 101 and the bottom surface 103 of the casing 100 are both provided with rails 600, and the mounting ring 200 is provided with a roller 202 at a position corresponding to the rails 600. The rail 600 extends to the back side 104 of the housing 100 and penetrates the back side 104 of the housing 100. Thus, when the case 100 is mounted, the rail 600 is aligned with the roller 202, and then the case 100 is inserted into the mounting ring 200. In the device, the top surface 101 of the shell 100 is provided with two rails 600, the bottom surface 103 is also provided with two rails 600, and the mounting ring 200 is provided with two rollers 202 corresponding to each rail 600, so that the mounting stability is ensured.

Referring to fig. 1, the mounting clips 400 on both sides of the housing 100 are symmetrically arranged, and the transverse length of the inner ring of the mounting ring 200 is greater than that of the housing 100, so that gaps are left between the mounting ring 200 and both sides of the housing 100 for the mounting clips 400 to pass through.

After the housing 100 is inserted into the mounting ring member 200, that is, the housing 100 moves backwards, in the blocking mechanism 300, a distance is also left between the blocking piece 303 and the side wall of the housing 100, and the distance between the blocking piece 303 and the housing 100 is designed, after the elastic piece 401 on the mounting clip 400 is tightened, the mounting clip 400 can completely pass between the blocking piece 303 and the housing 100, and after the mounting clip 400 completely passes, because the elastic piece 401 recovers the elastic force, at this time, the blocking plate 402 collides with the blocking piece 303, and the housing 100 cannot move forwards. If the housing 100 has contacted the inside of the mounting groove 501 at this time, the mounting of the housing 100 is completed.

As shown in fig. 2 and 7, when the casing 100 or the electronic device inside the casing 100 needs to be repaired, the electromagnet 301 can be activated, the key sheet 105 is disposed on the front surface 102 of the casing 100, the key sheet 105 is disposed with the blocking switch 106, and the blocking switch 106 is connected to the electromagnet 301 for controlling the electromagnet 301 to be activated and deactivated. After the electromagnet 301 is electrified, the blocking block 303 is adsorbed, and after the blocking block 303 is dislocated with the elastic sheet 401, the blocking block 303 does not block the blocking plate 402, so that the shell 100 can be taken out.

The electromagnet 301 is installed in a box body 304, when the electromagnet 301 is powered off, the spring 302 pushes the blocking block 303 out of the box body 304, when the electromagnet 301 is powered on, the electromagnet 301 adsorbs the blocking block 303 into the box body 304, and at the moment, the whole blocking mechanism 300 does not block the installation clamping piece 400.

In one possible design, as shown in fig. 4, the middle of the elastic piece 401 is connected to the side wall of the housing 100 by a reinforcing rib 403. Plays a reinforcing role to prevent the elastic piece 401 from being collided by the blocking block 303, and the shell 100 is pulled outwards, so that the elastic piece 401 is bent outwards.

In one possible design, as shown in fig. 1, the housing 100 is provided with heat dissipation holes 107.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
