It is a data terminal unit that mainly realizes the data acquisition and storage of various types of monitoring instruments and meters, and can complete the data transmission function with the host computer. It has independent data processing function;

[0003] When the equipment is running, a lot of heat will be generated. Therefore, the main chassis of the equipment needs to be cooled. Currently, multiple cooling holes are opened at the position where the cooling fan is installed, and the cooling holes are also open when the equipment is not running, which makes it easy for dust to enter the filter plate, reducing the service life of the filter plate. In addition, the existing equipment is not conducive to the disassembly and installation of the filter plate, and the filter plate is mostly installed at the air inlet position in front of the fan. When the equipment is not running, some dust on the filter plate will be sucked into the equipment due to static electricity, thereby affecting the service life of the equipment. For this reason, we propose a chassis dustproof device for a data acquisition and transmission instrument to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1-6 As shown, the utility model provides a chassis dustproof device for a data acquisition and transmission instrument, including a main body 1, a first shell 2 is fixedly installed on one side of the main body 1, a second shell 3 is fixedly installed on one side of the first shell 2, a filter plate 34 is slidably provided on one side of the second shell 3, one side of the filter plate 34 passes through one side of the second shell 3, the filter plate 34 passes through one side of the second shell 3 and passes through one side of the main body 1, four symmetrically distributed springs 321 are provided on both sides of the second shell 3, one end of each of the plurality of springs 321 is fixedly installed with a limiting bead 33, a third shell 4 is fixedly installed on one side of the second shell 3 away from the first shell 2, a fan 41 is rotatably installed in the middle of one side of the third shell 4, and a driving assembly is provided in the middle of the other side of the third shell 4.

[0021] A plurality of first rotating shafts 22 distributed at equal intervals are fixedly installed on the middle opposite sides of the first shell 2, and first baffles 21 are rotatably installed on the outer surfaces of the plurality of first rotating shafts 22. Both sides of the plurality of first baffles 21 are in contact with the inner wall of the first shell 2. By setting the first baffles 21, when the fan 41 is not running, the first baffle 21 naturally sags under the gravity of the first baffle 21, so that the filter plate 34 is isolated from the outside, thereby increasing the service life of the filter plate 34. A fourth shell 5 is fixedly installed on the side of the third shell 4 away from the second shell 3, and a plurality of second baffles 51 distributed at equal intervals are provided on the middle opposite sides of the fourth shell 5. By setting the second baffles 51, when the fan 41 is not running, the second baffle 51 naturally sags under the gravity of the second baffle 51, so that the inside of the main body 1 is isolated from the filter plate 34, thereby preventing dust on the filter plate 34 from being brought into the inside of the main body 1 due to static electricity when the machine stops running.

[0022] The driving assembly includes a motor 42 , one side of the motor 42 is fixedly mounted on the middle of one side of the third housing 4 , and the middle of one side of the fan 41 is fixedly mounted on the driving end of the motor 42 .

[0023] A plurality of second rotating shafts 52 distributed at equal intervals are fixedly mounted on opposite sides of the middle of the fourth housing 5 , and upper portions of the plurality of second baffles 51 are rotatably mounted on outer surfaces of the second rotating shafts 52 .

[0024] A sliding groove 31 is formed on the inner wall of the second housing 3 , and the filter plate 34 is slidably mounted inside the sliding groove 31 .

[0025] Four symmetrically distributed limiting grooves 341 are formed on both sides of the filter plate 34 , and the plurality of limiting beads 33 are slidably clamped in the limiting grooves 341 .

[0026] Four symmetrically distributed grooves 32 are provided on both sides of the slide groove 31, and multiple springs 321 are fixedly installed inside the groove bodies 32. By setting the groove bodies 32, when the filter plate 34 is pushed into the second shell 3 through the slide groove 31, the limiting beads 33 will be squeezed to shrink into the groove bodies 32 first. When the filter plate 34 reaches the specified position, the limiting groove 341 is located in front of the limiting beads 33. Under the reaction force of the spring 321, the limiting beads 33 are ejected to limit and fix the filter plate 34.

[0027] A handle 342 is fixedly mounted on the filter plate 34 passing through the middle of one side of the body 1 .

[0028] Working principle: In actual use, the filter plate 34 is placed into the second housing 3 through the slide groove 31. When pushing it in, the limiting bead 33 is first squeezed to slide into the groove body 32. When the filter plate 34 reaches the specified position, the limiting groove 341 is located in front of the limiting bead 33. Under the reaction force of the spring 321, the limiting bead 33 is pushed out of the groove body 32 and then stuck in the limiting groove 341. That is, the filter plate 34 is fixed. When the filter plate 34 needs to be disassembled, cleaned or replaced, the filter plate 34 can be pulled out by directly pulling the handle 342.

[0029] By starting the motor 42 to drive the fan 41 to rotate, the external wind is sucked into the main body 1 to cool the internal equipment of the main body 1. When the wind is sucked inward, the lower part of the first baffle 21 is driven to tilt backward so that the first baffle 21 directly has a gap to allow air to enter. A second baffle 51 is provided on the rear side of the fan 41. When the wind blows inward, the lower part of the second baffle 51 is tilted away from the fan 41, so that air enters the main body 1 to cool the internal equipment. When the motor 42 is not started to drive the fan 41 to rotate, the first baffle 21 and the second baffle 51 naturally tilt downward due to the gravity, so that the first baffle 21 and the first baffle 21, the second baffle 51 and the second baffle 51 are directly in contact with each other, so that the inside of the main body 1 is closed from the outside.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
