[0022] 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.

[0023] Example 1

[0024] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5The present invention provides the following technical solution: a digital display saccharimeter 1 that is easy to protect, including a saccharimeter 1, wherein grooves are provided on both the front and rear sides of the saccharimeter 1, and a recovery mechanism 2 is provided in the grooves. The side view cross-sectional shape of the groove is a T-shape rotated 90 degrees.

[0025] The recovery mechanism 2 includes a slide rod 21 fixed in the groove, a sliding sleeve 22 slidably connected to the surface of the slide rod 21, a fixing plate 23 fixedly connected to the surface of the sliding sleeve 22, and a spring 24 provided on one side of the slide rod 21 located on the fixing plate 23. The elastic force of the spring 24 can automatically restore the moved protective plate 32 to its original position, which is suitable for solution detection work that requires shielding. The fixing plate 23 is rectangular and its size is adapted to the inside of the groove.

[0026] Two fixed plates 23 are fixedly connected to the protective device 3. The protective device 3 includes a connecting rod 31 and a protective plate 32 provided on the side of the connecting rod 31. The two ends of the connecting rod 31 are fixedly connected to the sides of the two fixed plates 23. The connecting rod 31 is an arched connecting rod 31. The two sides of the connecting rod 31 are provided with protruding levers. The levers facilitate the movement of the connecting rod 31 by the operator, and further facilitate the movement of the protective plate 32. The protective plate 32 is a semi-circular plate. The protective plate 32 is located above the drip port of the saccharimeter 1. The semi-circular plate is located above the drip port. By fitting against the surface of the saccharimeter 1, the drip port can be sealed and protected.

[0027] The working principle of this embodiment is as follows:

[0028] During use, the operator can move the lever to move the connecting rod 31 and the protective plate 32, causing the protective plate 32 to be misaligned with the drip nozzle. At this time, the spring 24 on one side is compressed. After the solution is dripped in, the lever is released, and the restoring force of the spring 24 causes the fixing plate 23 to move the protective plate 32 through the connecting rod 31, thereby sealing the drip nozzle with the protective plate 32, which facilitates the detection of the solution.

[0029] Example 2

[0030] Please see Figure 1 , Figure 3 and Figure 4 The present invention provides the following technical solution: a digital display saccharimeter 1 that is easy to protect, including a saccharimeter 1, wherein grooves are provided on both the front and rear sides of the saccharimeter 1, and a recovery mechanism 2 is provided in the grooves. The side view cross-sectional shape of the groove is a T-shape rotated 90 degrees.

[0031] The recovery mechanism 2 includes a slide rod 21 fixed in the groove, a slide sleeve 22 slidably connected to the surface of the slide rod 21, and a fixing plate 23 fixedly connected to the surface of the slide sleeve 22. The fixing plate 23 is rectangular and its size is adapted to the inside of the groove.

[0032] Two fixing plates 23 are fixedly connected to the protective device 3 respectively. The protective device 3 includes a connecting rod 31 and a protective plate 32 provided on the side of the connecting rod 31. The two ends of the connecting rod 31 are fixedly connected to the sides of the two fixing plates 23. The connecting rod 31 is an arched connecting rod 31. Protruding paddles are provided on both sides of the connecting rod 31. The protective plate 32 is a semi-circular plate. The protective plate 32 is located above the drip port of the saccharimeter 1.

[0033] The working principle of this embodiment is as follows:

[0034] During use, the operator can move the lever to move the connecting rod 31 and the protective plate 32, causing the protective plate 32 to be misaligned with the drip nozzle. The protective plate 32 is limited by the friction between the sliding sleeve 22 and the sliding rod 21. After the solution is dripped in, the lever can be moved to seal the drip nozzle with the protective plate 32, which facilitates the detection of the solution.
