A locking mechanism 2 is fixedly installed on the top of the battery compartment 8. When installing the battery assembly, the locking plate 3 is inserted into the locking mechanism 2 to fix the battery assembly. To improve the stability after installation, a sliding post 7 is fixedly installed on the side wall inside the battery compartment 8. Sliding grooves 6 that cooperate with the sliding post 7 are opened on both sides of the battery box 5. During installation, the sliding grooves 6 are combined with the sliding post 7, and after sliding, the locking plate 3 is inserted into the locking mechanism 2 to fix the battery assembly. The installation is convenient.

[0028] Reference Figure 3 Furthermore, the locking mechanism 2 includes a mounting bracket 201 fixedly connected to the top of the battery compartment 8. A movable bracket 208 is connected inside the mounting bracket 201 via a first spring 209. A retainer 207 is fixedly installed on the bottom inner side of the movable bracket 208. The side of the retainer 207 facing the locking plate 3 is arc-shaped, facilitating quick and easy installation. During installation, the locking plate 3 presses against the retainer 207, and after the locking plate 3 is inserted, the retainer 207 is lifted by the first spring 209 and engages with the retaining hole on the locking plate 3, thus securing the locking plate 3. A pressure post 204 is fixedly installed on the top of the movable bracket 208. During unlocking, pressing the pressure post 204 disengages the retainer 207 from the retaining hole on the locking plate 3, allowing the battery assembly to be removed. The operation is simple and convenient.

[0029] The top of the pressure column 204 is threadedly connected to a sealing plate 202. A screw is fixedly installed at the bottom center of the sealing plate 202. A screw hole 206 that mates with the screw is opened at the top center of the pressure column 204. After the battery assembly is installed, the pressure column 204 is fixed by the sealing plate 202 to prevent vibration from causing the card holder 207 to detach from the locking plate 3, thereby improving stability. By rotating the sealing plate 202, the screw is connected to the screw hole 206. After tightening, the pressure column 204 is fixed. Multiple anti-slip posts 203 are installed in a ring shape on the top of the sealing plate 202, making it more convenient and quick to rotate the sealing plate 202. A sealing groove 205 is opened on the top of the mounting bracket 201 outside the pressure column 204.

In the event of a battery failure or explosion, the resulting impact force strikes the baffle 901, compresses the second spring 904 and the damper 903, and then the vent 906 extends to the outside of the battery box 5. The airflow generated inside the battery box 5 overflows through the vent 906, effectively releasing the pressure inside the battery box 5 and reducing the destructive force of the explosion shock wave. The back plate 4 is installed on the outside of the battery box 5 to seal the gap between the battery box 5 and the battery compartment 8, improving the sealing effect.

[0031] Specifically, when using the battery locking device of this explosion-proof walkie-talkie: the battery assembly is slid into the battery compartment 8 after being combined with the sliding column 7 via the sliding groove 6, and then locked into the locking mechanism 2 by the locking plate 3. The card holder 207 is locked into the card hole on the locking plate 3 under the action of the first spring 209, fixing the locking plate 3 and keeping the battery assembly fixed. After completion, the sealing plate 202 is installed, which is connected to the pressure column 204 by rotation, fixing the pressure column 204 and keeping the card holder 207 stable during use.
