In the above drawings: 1. a body; 2. a reading tube; 3. adjusting a rod; 4. a slider; 5. an observation mirror; 6. a reading buoy; 7. Reading scales; 41. a rubber layer; 61. reading and marking; 62. a cavity; 63. a gravity bar.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1-3, the embodiment of the present invention provides a measuring cup convenient for observation, which includes a body 1, a reading tube 2, an adjusting rod 3 and an observation mirror 5; the reading tube 2 is arranged along the vertical direction, two ends of the reading tube are respectively communicated with the upper part and the lower part of the body 1, reading scales 7 are arranged on the reading tube 2, and a reading buoy 6 is arranged inside the reading tube 2; the upper part of the reading buoy 6 is provided with a reading mark 61, and the adjusting rod 3 is fixed on the body 1 and is parallel to the reading tube 2; the observation mirror 5 is a magnifying glass, the observation mirror 5 is connected on the adjusting rod 3 in a sliding mode, and the mirror surface of the observation mirror is arranged towards the reading tube 2.
Further, in order to make the reading easier to observe, the observation mirror 5 is arranged obliquely.
Further, the lower end of the adjusting rod 3 is lower than the lower end of the reading tube 2, and the upper end of the adjusting rod 3 is higher than the upper end of the reading tube 2. So that the scope 5 adjustment covers the entire reading tube 2.
Further, a sliding block 4 is arranged on the adjusting rod 3, the observation mirror 5 is arranged on the sliding block 4, a through hole for the adjusting rod 3 to pass through is formed in the sliding block 4, and an elastic rubber layer 41 is arranged on the inner wall of the through hole. Certain resistance is generated between the rubber layer 41 and the adjusting rod 3, and certain axial pressure is given by the inclined arrangement of the observation mirror 5, so that the observation mirror 5 cannot automatically slide down due to gravity after adjustment, and the reading can be carried out by taking off the hand.
Furthermore, the upper end of the reading buoy 6 is a plane, and the lower part of the reading buoy protrudes downwards; the reading buoy 6 is internally provided with a cavity 62. The edge of the plane is provided with a reading mark 61, and the reading mark 61 is a circle of color ring at the upper part of the reading buoy 6 and is used for corresponding to the scale, so that the reading is convenient; when the reading scale 7 is arranged, the reading influence caused by the gravity influence of the reading buoy 6 is considered in advance, and the influence of inconsistent height of the liquid level floated by the reading buoy 6 due to the density of the liquid is extremely small, so that the influence is ignored.
Furthermore, the upper end of the reading buoy 6 is a circular surface, the diameter of the upper end is smaller than the inner diameter of the reading tube 2, and the edge of the upper end is close to the inner wall of the reading tube 2; the reading scale 7 is positioned on the inner wall of the reading tube 2. The upper diameter of reading buoy 6 slightly is less than the internal diameter of reading tube 2 for reading buoy 6 neither is restricted by reading tube 2 and floats up, can be more closely with the inner wall again, and reading scale 7 sets up on the inner wall, makes reading scale 7 and reading mark 61 be close to very closely, even so reading angle is great from the top inclination, also is very little to actual reading influence.
Further, the diameter of the communication hole between the reading tube 2 and the body 1 is smaller than the diameter of the upper end of the reading buoy 6, and the lower end of the reading buoy 6 is provided with a gravity rod 63 along the vertical direction. The diameter of the communicating hole is smaller than that of the upper end of the reading buoy 6, so that the reading buoy 6 cannot fall out of the reading tube 2 after liquid is poured out; the gravity rod 63 can enable the reading buoy 6 to be floated to enable the upper end to be in a relatively horizontal state, and can also prevent the reading buoy 6 from turning over in the reading tube 2; meanwhile, the reading buoy 6 can be prevented from blocking the communication hole after the liquid is poured out.
According to the above technical scheme, the utility model discloses a theory of operation does: when liquid enters the body 1, the water level in the observation pipe rises along with the liquid, and the reading buoy 6 floats; the position of the observation mirror 5 is then adjusted to be approximately aligned with the position of the reading buoy 6, and after the buoy is stabilized, the reading is carried out through the observation mirror 5.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
