[0002] GPS locator is a mature technology, which is applied to automobile, external equipment and water and soil conservation. GPS locator has been widely used. When GPS is used in water and soil conservation, the outside is generally protected by a plastic shell. In the process of protecting GPS, the existing plastic shell does not have a good waterproof structure inside, and it is easy to be soaked in water at the connection between the bottom shell and the top shell, causing damage to the internal GPS components and affecting the use of the equipment.

[0003] At present, in the prior art, for example, a Chinese patent with announcement number CN218037353U discloses a plastic shell of a waterproof GPS locator. The plastic shell of the waterproof GPS locator has a first annular plug plate and an annular groove between the top shell and the bottom shell, so that the two can be easily installed and disassembled, the sealing is improved, and the dust and water effects are achieved, thereby protecting the internal GPS locator.

[0004] However, in farmland and land, after a long period of wind and sun, it is difficult to avoid the presence of moisture and dust in the GPS locator and its shell. If it is just convenient for installation and disassembly, then when there is moisture inside, personnel still need to manually wipe the internal moisture, which is very troublesome. In view of this, we propose a GPS locator with a waterproof mechanism. Utility Model Content

When the stopper 5 is pulled outward, the stopper 5 will squeeze the tension spring 6 inward, shorten the length of the tension spring 6, and generate kinetic energy for rebounding outward at the same time.

[0029] In an embodiment of the utility model, a rubber plate 7 is movably connected to the inner wall of the inner groove 3, and a socket 8 is provided on the inner wall of the rubber plate 7. The rubber plate 7 can slide up and down on the inner wall of the inner groove 3. When the rubber plate 7 is inserted to the lowest end of the inner groove 3, the stopper 5 will be snapped into the socket 8. A support plate 9 is fixedly connected to the outer wall at the top of the rubber plate 7, and a placement rack 10 is fixedly connected to the outer wall of the support plate 9. The placement rack 10 is used to place the GPS locator, and a large number of holes are provided on the surface of the placement rack 10 for dissipating and dissipating the heat and moisture generated when the locator is working. A handle 11 is fixedly connected to the outer wall at the top of the support plate 9. By pulling the handle 11, the rubber plate 7 can be driven through the support plate 9 to enter the inner groove 3 of the inner plate 2.

[0030] In an embodiment of the utility model, a sliding column 12 is fixedly connected to the outer wall of the bottom end of the support plate 9, a slide groove 13 is fixedly connected to the outer wall of the inner plate 2, and the sliding column 12 is slidably connected to the inner wall of the slide groove 13, and the sliding column 12 can slide up and down on the inner wall of the slide groove 13, and a first rotating shaft 14 is rotatably connected to the outer wall of the bottom end of the sliding column 12, and the first rotating shaft 14 can rotate in a small range on the surface of the sliding column 12, and a bottom rod 15 is fixedly connected to the outer wall of the first rotating shaft 14, and the bottom rod 15 can adjust the angle in a small range at the bottom end of the sliding column 12 through the first rotating shaft 14, and a second rotating shaft 16 is rotatably connected to the outer wall of the bottom rod 15, and a connecting plate 17 is fixedly connected to the outer wall of the second rotating shaft 16, and the connecting plate 17 can adjust the angle through the second rotating shaft 16.

[0031] In an embodiment of the utility model, a rolling column 18 is rotatably connected to the outer wall of the connecting plate 17. The rolling column 18 can rotate on the surface of the connecting plate 17, and when the angle of the connecting plate 17 is adjusted, the rolling column 18 will also be driven to change its position. A telescopic column 19 is arranged on the outer wall of the rolling column 18. When the two groups of rolling columns 18 shrink inward and approach each other, the telescopic column 19 will be squeezed, and a telescopic spring 20 is arranged on the inner wall of the telescopic column 19. When the telescopic column 19 is squeezed, the length of the telescopic spring 20 will be shortened and it will have the kinetic energy to pop outward. A collecting groove 21 is arranged on the inner wall of the protective shell 1, and the moisture dropped from the placement rack 10 can be collected through the collecting groove 21.

[0032] In the utility model, when in use, the GPS locator is placed in the placement rack 10, and then the staff holds the handle 11 and places the placement rack 10 towards the inside of the protective shell 1. At this time, the rubber plate 7 will be placed in the inner groove 3 opened by the inner plate 2. The rubber plate 7 itself has the characteristics of large friction and can generate greater resistance when slidingly connected with the inner groove 3, which can prevent the rubber plate 7 and the inner groove 3 from having an unstable connection, and the rubber plate 7 and the inner groove 3 fit very well, effectively preventing some dust and particles from entering the protective shell 1.

[0033] Next, when the rubber sheet 7 enters the inner groove 3, the stopper 5 is pushed out a long distance when the rubber sheet 7 is not put in. After the rubber sheet 7 enters, the surface of the rubber sheet 7 will push and squeeze the stopper 5 inward, causing the stopper 5 to shrink inward for a distance and squeeze the tension spring 6 inward. At the same time, the tension spring 6 will generate kinetic energy to pop outward. At this time, when the rubber sheet 7 reaches the bottom of the inner groove 3, the socket 8 will reach the same horizontal height of the stopper 5. At this time, the stopper 5 is no longer subject to the squeezing force and will pop outward and snap into the socket 8, so that the stopper 5 is fixed to the rubber sheet 7. At this time, the placement frame 10 will be completely fixed to the protective shell 1, and the top of the placement frame 10 is set A device such as a top protective shell 1 is provided to better protect the GPS locator, prevent dust and sand from entering the protective shell 1, and prevent strong winds in farmland or land from blowing the placement rack 10 and causing it to detach from the protective shell 1. At the same time, it is only necessary to pull out the stopper 5 so that the stopper 5 drives the tension spring 6 to squeeze inward, so that the stopper 5 and the socket 8 are separated, and the rubber plate 7 and the inner plate 2 can be released. After the rubber plate 7 is released, it is only necessary to loosen the stopper 5 so that the tension spring 6 drives the stopper 5 to rebound to its original position. Without too much complicated operation, the rubber plate 7 and the inner plate 2 can be released and the placement rack 10 can be detached from the protective shell 1.

[0034] At the same time, during routine maintenance or repair of the GPS locator, the placement rack 10 is separated from the protective shell 1. At this time, if it rains or moisture enters the protective shell 1, if the GPS locator is directly placed in the protective shell 1, the internal humid environment or moisture may damage the GPS locator. At this time, the handle 11 is held to drive the placement rack 10 downward. At this time, the support plate 9 will push the sliding column 12 downward, and the sliding column 12 will drive the connecting plate 17 to move downward. The inner wall of the protective shell 1 is provided with a collecting groove 21, and then the connecting plate 17 will drive the roller 17 to move downward. The moving column 18 pushes toward the surface of the collecting groove 21. If there is deposited dew or moisture on the surface of the collecting groove 21, the rolling column 18 will roll the moisture away. The rolling column 18 is a soft hair that can absorb moisture and can self-clean by absorbing part of the moisture. If the inclination of the surface of the collecting groove 21 does not match the angle of the rolling column 18, the connecting plate 17 can be rotated on the surface of the bottom rod 15 through the second rotating shaft 16, so that the connecting plate 17 can drive the rolling column 18 to achieve adjustment at different angles, so that the rolling column 18 can fit the surface of the collecting groove 21 more closely.

[0035] Furthermore, when the two groups of rolling columns 18 simultaneously move downward to remove moisture from the surface of the collecting groove 21, the two groups of rolling columns 18 will shrink closer to each other, which will squeeze the telescopic column 19. At this time, the length of the telescopic spring 20 will be shortened, and it will have the kinetic energy to pop outward. After removing moisture downward once, the rubber plate 7 and the inner plate 2 will be released from the fixation, and the pressure of the two groups of telescopic columns 19 will be released, so that the kinetic energy of the telescopic spring 20 will be released, and the two groups of rolling columns 18 will pop outward and upward, and the moisture in the collecting groove 21 will be scraped off again. At this time, the upward rolling column 18 will drive the sliding column 12 to push upward in the slide groove 13, and then the support plate 9 will be moved away from the protective shell 1, so that the placement rack 10 can be quickly separated from the protective shell 1 while the fixation of the rubber plate 7 and the inner plate 2 is released.
