[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figures 1-6As shown, this utility model provides a protective device for a data acquisition terminal, including a bracket 1 and a data acquisition terminal body 2. The data acquisition terminal body 2 is a GPRS terminal device integrating measurement, metering, acquisition and communication functions, which is the prior art and will not be described in detail here. A mounting hole 16 for use is opened through one side of the bracket 1, and the mounting hole 16 has a symmetrical structure. The use of the mounting hole 16 provides a guarantee for the stable installation of the bracket 1. The data acquisition terminal body 2 and the bracket 1 are detachably connected, and the bracket 1 is provided with a protective mechanism 3 for use with the data acquisition terminal body 2.

[0022] The protective mechanism 3 includes a sliding rod 31, a fixed plate 32, and a rotating shaft 33. The sliding rod 31 is slidably inserted into one end of the bracket 1, and a protective plate 34 is fixedly fitted onto the top end of the sliding rod 31. A sliding hole 14 is provided through the bracket 1, and the sliding rod 31 is slidably inserted into the sliding hole 14. The sliding hole 14 serves to limit and guide the movement of the sliding rod 31. A symmetrically arranged guide rod 311 is fixedly inserted into one end of the protective plate 34 near the sliding rod 31. A sliding through bracket 1 is provided, with symmetrically distributed guide holes 13 extending through one end of the bracket 1. A guide rod 311 is slidably inserted into the guide hole 13. A protective plate 34 is provided with symmetrically arranged insertion holes 312 extending through one end of the protective plate 34. The top end of the guide rod 311 is fixedly inserted into the insertion hole 312. The cooperation of the insertion hole 312, the guide rod 311, and the guide hole 13 ensures the stable lifting and lowering of the protective plate 34. A limit rack 35 is fixedly connected to the bottom end of the sliding rod 31. A collar 36 is fixedly fitted onto the support 1. A spring 37 is fixedly connected to the bottom end of the collar 36, and the end of the spring 37 is fixedly connected to the support 1. Two sliding grooves 11 are opened through the support 1, and the fixing plate 32 is slidably locked in the sliding grooves 11. L-shaped grooves 21 are opened on both sides of the data acquisition terminal body 2, and the upper end of the fixing plate 32 can be slidably inserted into the L-shaped grooves 21. A connecting rack 38 is fixedly connected to the bottom end of the fixing plate 32, and the rotating shaft 33 is rotatably inserted into the rack. On the bracket 1, a gear 39 is fixedly sleeved at the bottom end of the rotating shaft 33. A rotating hole 15 is opened through the middle of the bracket 1, and the rotating shaft 33 is rotatably inserted into the rotating hole 15. The setting of the rotating hole 15 provides a guarantee for the stable rotation of the rotating shaft 33. A torsion spring 310 is fixedly connected to the inner side of the upper end of the gear 39, and the end of the torsion spring 310 is fixedly connected to the bracket 1. Both connecting racks 38 mesh with the gear 39, and the limiting rack 35 can mesh with the gear 39.

[0023] By adopting the above technical solution, when in use, the bracket 1 is fixed in a suitable position by the cooperation of the mounting bolt and the mounting hole 16. Then, the protective plate 34 is pressed down, which can drive the slide rod 31 to move down, and then drive the limiting rack 35 and the collar 36 to move down synchronously. Furthermore, the limiting rack 35 can gradually misalign with the gear 39 and gradually squeeze the spring 37. When the gap between the collar 36 and the bracket 1 is moved to the minimum, the pressure on the protective plate 34 is stopped. At this time, the limiting rack 35 will be completely separated from the gear 39. Then, the fixed plate 32 away from the slide rod 31 is pulled, which can drive the corresponding connecting rack 38 to move. Then, the gear 39 can drive another connecting rack 38 to move in the opposite direction to the fixed plate 32 and twist the torsion spring 310.

[0024] When the distance between the two fixing plates 32 reaches its maximum, stop pulling the corresponding fixing plate 32. Then, accurately place the data acquisition terminal body 2 and release the corresponding fixing plate 32. At this time, the torsion spring 310 will drive the gear 39 to reverse, so that the two fixing plates 32 can move towards each other through the connecting rack 38 and be inserted into the corresponding L-shaped groove 21. Then, release the protective plate 34. At this time, the spring 37 will drive the collar 36 to move upward and reset, which in turn will drive the slide rod 31 to move upward and reset. Furthermore, it will drive the protective plate 34 and the limiting rack 35 to move upward and reset, and make the limiting rack 35 mesh with the gear 39 again, thus realizing the convenient and stable installation of the data acquisition terminal body 2.

[0025] Alignment posts 22 are fixedly connected to the four corners of the bottom of the data acquisition terminal body 2. Alignment holes 12 are symmetrically distributed through the top two sides of the bracket 1, and the alignment posts 22 can be slidably inserted into the alignment holes 12.

[0026] By adopting the above technical solution, the cooperation between the alignment post 22 and the alignment hole 12 facilitates the precise placement of the data acquisition terminal body 2, thereby facilitating the precise fixation of the data acquisition terminal body 2 and effectively improving the installation stability of the data acquisition terminal body 2.

[0027] Working principle: In use, the bracket 1 is fixed in a suitable position by the cooperation of the mounting bolt and the mounting hole 16. Then, the protective plate 34 is pressed down, which can drive the slide rod 31 to move down, and then drive the limiting rack 35 and the collar 36 to move down synchronously. Further, the limiting rack 35 can gradually misalign with the gear 39 and gradually squeeze the spring 37. When the gap between the collar 36 and the bracket 1 is moved to the minimum, the pressure on the protective plate 34 is stopped. At this time, the limiting rack 35 will be completely separated from the gear 39. Then, the fixed plate 32 away from the slide rod 31 is pulled, which can drive the corresponding connecting rack 38 to move. Then, the gear 39 can drive another connecting rack 38 to move in the opposite direction to the fixed plate 32 and twist the torsion spring 310.

[0028] When the distance between the two fixing plates 32 reaches its maximum, stop pulling the corresponding fixing plate 32. Then, hold the data acquisition terminal body 2 and insert the alignment post 22 at its bottom into the corresponding alignment hole 12. Then release the corresponding fixing plate 32. At this time, the torsion spring 310 will drive the gear 39 to reverse, so that the two fixing plates 32 can move towards each other through the connecting rack 38 and be inserted into the corresponding L-shaped groove 21. Then release the protective plate 34. At this time, the spring 37 will drive the collar 36 to move up and reset, which in turn will drive the slide rod 31 to move up and reset, and further drive the protective plate 34 and the limiting rack 35 to move up and reset, and make the limiting rack 35 mesh with the gear 39 again, thus realizing the convenient and stable installation of the data acquisition terminal body 2.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
