A mounting block 8 is connected through and fixedly connected to the middle of the top wall of the waterproof cover 7. A mounting cavity 14 is provided in the middle of the bottom wall of the mounting block 8. A screw 10 is threadedly connected to the middle of the top wall of the mounting cavity 14. A torsion block 11 is fixedly connected to the top of the screw 10. Rotating the torsion block 11 causes the screw 10 to rotate. During rotation, the screw 10 can move up and down. A pressure block 21 is rotatably connected to the bottom of the screw 10. The bottom left and right sides of the pressure block 21 are arc-shaped, allowing for gradual downward movement. A pushing force is gradually applied to the two side blocks 16 to move outward. Openings 15 are provided in the lower middle part of the left and right side walls of the mounting cavity 14. Blocks 16 are slidably connected to the inside of the openings 15. After the blocks 16 are pressed against the side wall of the slot 6, the mounting block 8 can be fixed. Connecting plates 17 are fixedly connected to the middle of the front and rear side walls of the blocks 16. Limiting rods 18 are slidably connected through the middle of the connecting plates 17. Pressure grooves 20 are provided in the middle of the side wall of the two sets of blocks 16 that are close to each other. The limiting rods 18 can restrict the connecting plates 17 and cooperate with the spring 19 to allow the blocks 16 to be reset.

[0026] The other end of the limiting rod 18 is fixedly connected to the inner wall of the mounting cavity 14. The pressure block 21 is clearance-fitted with the pressure groove 20. The end of the connecting plate 17 near the inner side wall of the mounting cavity 14 is fixedly connected with a spring 19. The spring 19 is clearance-fitted with the limiting rod 18. The spring 19 can pull the locking block 16 after the pressure block 21 is pulled out from the inside of the pressure groove 20.

[0027] A slot 6 is provided in the middle of the top wall of the receiver housing 1. The slot 6 is in clearance fit with the mounting block 8.

The control panel 3, control buttons 4 and base rod 5 are all components that come with the GNSS receiver and belong to the prior art.

[0029] Working principle: When waterproofing the GNSS receiver is required, insert the mounting block 8 into the slot 6 and rotate the torsion block 11. The rotation of the torsion block 11 causes the screw 10 to rotate. During the rotation of the screw 10, it moves downward, causing the pressure block 21 to move down and insert into the inside of the pressure groove 20. During the downward movement of the pressure block 21, the two sets of locking blocks 16 move away from each other. After the locking blocks 16 extend out of the opening 15 and contact the side wall of the slot 6, they fix the mounting block 8, completing the installation of the protective cover. After the waterproof mechanism 2 is installed, insert the connecting shell 12 into the connecting groove 9, so that the screw 10 and the torsion block 11 are located inside the waterproof shell 13. This can protect the screw 10, prevent it from rusting and becoming unusable, and improve the service life of the waterproof mechanism 2.
