[0021] Example, by Figure 1-6 The utility model includes a main casing 1, a first opening 2 and two second openings 3 distributed up and down are opened on the front side of the main casing 1, the first opening 2 is located between the two second openings 3, a protective cover 4 is installed on the front side of the main casing 1, the protective cover 4 is composed of a connecting plate 5 and a connecting cover 6, the connecting cover 6 is integrally formed and connected to the front side of the connecting plate 5, the first opening 2 is located behind the connecting cover 6, a plurality of third openings 10 are opened on the front side of the connecting plate 5, the third openings 10 are located in front of the second openings 3, a plurality of locking mechanisms are penetrated and connected on the front side of the connecting plate 5, the connecting cover 6 is located between the plurality of locking mechanisms, the locking mechanism penetrates the third opening 10 and the second opening 3 and extends to the inside of the main casing 1, and the protective cover 4 is fixedly connected to the front side of the main casing 1 through the locking mechanism.

[0022] The locking mechanism includes a pressing plate 11, which is located in front of the third opening 10. An L-shaped hook 12 is fixedly connected to the rear side of the pressing plate 11. The L-shaped hook 12 passes through the third opening 10 and the second opening 3 and extends to the inside of the main housing 1. A spring 13 is fixedly connected to the side of the L-shaped hook 12 away from the inner wall of the second opening 3. One end of the spring 13 away from the L-shaped hook 12 is fixedly connected to the inner wall of the third opening 10. The L-shaped hook 12 in the locking mechanism is similar to the snap-fit ​​structure in the comparative document CN201921850380.2, but the L-shaped hook 12 is movable. When disassembling the protective cover 4, you only need to move the L-shaped hook 12 so that it no longer snaps on the main housing 1, and the L-shaped hook 12 will not be damaged due to violent dismantling.

[0023] A T-shaped slider 14 is fixedly connected to the rear side of the pressing plate 11, and a T-shaped groove 15 corresponding to the T-shaped slider 14 is opened on the front side of the connecting plate 5. The T-shaped slider 14 is slidably connected inside the T-shaped groove 15. The front side of the pressing plate 11 is processed with anti-slip grooves. The cooperation of the T-shaped slider 14 and the T-shaped groove 15 can make the pressing plate 11 slidably connected to the connecting plate 5, and also limit its moving stroke.

[0024] Two thickening blocks 9 are processed on the rear side of the connecting plate 5, and the thickening block 9 is located between the two third openings 10, and the thickening block 9 extends to the inside of the second opening 3. The thickening block 9 is inserted into the inside of the second opening 3, which can improve the stability of the protective cover 4 connected to the main housing 1, and also increase the inner wall width of the third opening 10 to facilitate the installation of the spring 13.

[0025] A frame 7 is fixedly connected to the rear side of the connecting plate 5, and the frame 7 extends to the inside of the first opening 2. The frame 7 is adapted to the inner wall of the first opening 2, and a sealing ring 8 is inlaid on the outer side of the frame 7. The outer end of the sealing ring 8 contacts the inner wall of the first opening 2. The cooperation between the frame 7 and the sealing ring 8 can improve the sealing between the protective cover 4 and the inner wall of the first opening 2.

[0026] Working principle:

[0027] After the Bluetooth module is installed inside the main housing 1, the Bluetooth module passes through the first opening 2 and extends to the front of the main housing 1, and then the protective cover 4 is covered in front of the first opening 2, and the Bluetooth module passing through the first opening 2 can extend into the connection cover 6, and the four locking mechanisms on the connection plate 5 can fix the protective cover 4 in front of the main housing 1 to protect the Bluetooth module;

[0028] When installing the protective cover 4, the frame 7 on the rear side of the connecting plate 5 can be inserted into the first opening 2, and the sealing ring 8 on the outside of the frame 7 can improve the sealing between the outside of the frame 7 and the inner wall of the first opening 2. When the locking mechanism passes through the second opening 3, the arc surface of the L-shaped hook 12 will contact the inner wall of the second opening 3, and the L-shaped hook 12 will move with the pressing plate 11 and squeeze the compression spring 13 due to the compression of the inner wall of the second opening 3. When the end of the L-shaped hook 12 completely passes through the second opening 3, the elastic force of the spring 13 will push the L-shaped hook 12 to approach and get stuck on the inner wall of the second opening 3. At this time, the L-shaped hook 12 passes through the second opening 3 and hooks the main housing 1 to fix the protective cover 4. When disassembling, you only need to press the two adjacent pressing plates 11 on the left and right and push them close to each other to release the restriction of the L-shaped hook 12 hooking the main housing 1, thereby quickly removing the protective cover 4 from the main housing 1.
