[0001] The utility model belongs to the technical field of test cups, in particular to a quantitatively sealed test cup. Background Art

[0002] The test cup can be used to hold the test liquid. The test cup is mostly made of transparent plastic material, so the test liquid condition and the test liquid level in the test cup can be directly observed. Scale lines are set on the surface of the test cup for easy observation.

[0003] Existing test cups are mostly directly sealed with ordinary covers during use. Since the test liquid level is affected by the field of view, the test liquid level in the test cup cannot be accurately read, which reduces the accuracy of liquid level measurement and cannot quantitatively seal the test liquid. Utility Model Content

[0004] The utility model aims to provide a quantitatively sealed test cup, which can adjust the distance between the bottom of the sealing plate and the outer surface of the liquid in the transparent test cup by toggling a toggle plate, and the provision of an air release pipe solves the problem that the existing test cups mostly use ordinary cover plates for direct sealing during use, and the test liquid level in the test cup cannot be accurately read because the test liquid level is affected by the field of view angle, which reduces the accuracy of liquid level measurement and cannot quantitatively seal the test liquid.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a quantitatively sealed test cup, comprising a transparent test cup; a cover plate is rotatably matched with the outer top thread of the transparent test cup, a lifting rod is slidably matched with the top of the cover plate, a sealing plate is fixed at the bottom of the lifting rod below the cover plate, and the sealing plate is slidably matched with the inner wall of the transparent test cup.

[0007] A lifting plate is fixed on the top of the lifting rod, a traction shaft is fixed on one side of the lifting plate, and the traction shaft is located on both sides of the lifting plate and is rotatably matched with a U-shaped plate.

[0008] A center plate is fixed at the center position of the top outside the cover plate, a limit plate is fixed on the top of the center plate, a center axis is fixed on one side of the limit plate, and the center axis is rotatably matched with the inner wall of the U-shaped plate; an arc spring is fixedly connected between the bottom of the U-shaped plate and the center plate.

[0012] The utility model is further configured that the outer wall of the transparent test cup is provided with a threaded rail.

[0013] The inner wall of the cover plate is provided with a thread groove, and the thread rail and the thread groove are threadably matched.

[0014] The utility model is further configured that a clamping top plate is arranged on the outer top of the transparent test cup.

[0015] An annular clamping groove for clamping and matching the top plate is provided at the top of the cover plate, and a sealing ring is provided between the top plate and the annular clamping groove.

[0016] The utility model is further configured that a sealing sleeve is provided on the peripheral side of the sealing plate.

[0019] The utility model has the following beneficial effects:

[0020] The utility model rotates the cover plate thread to fit the outer top of the transparent test cup. If the liquid in the transparent test cup contacts the bottom of the sealing plate, the cover plate is rotated to fit the outer top of the transparent test cup. Then, the U-shaped plate is driven to rotate around the central axis by the cover plate thread. Then, the distance between the bottom of the sealing plate and the outer surface of the liquid in the transparent test cup can be adjusted until the bottom of the sealing plate contacts the outer surface of the liquid in the transparent test cup. If the liquid in the transparent test cup does not contact the bottom of the sealing plate, the cover plate thread is rotated to fit the outer top of the transparent test cup. Then, the U-shaped plate is moved to adjust the distance between the bottom of the sealing plate and the outer surface of the liquid in the transparent test cup. Then, the U-shaped plate and the limit plate are fixedly connected by bolts. At this time, the liquid level in the transparent test cup can be observed, which is convenient for observing the amount of liquid in the transparent test cup. Thus, quantitative sealing of the test liquid is achieved, and the accuracy of measuring the liquid in the transparent test cup is effectively improved.

[0021] The utility model provides an air release pipe, and in the process of threaded rotation cooperation between the transparent test cup and the cover plate, and in the process of adjusting the distance between the sealing plate and the surface of the test liquid in the transparent test cup, air can be released from the cavity formed between the sealing plate and the transparent test cup, thereby adjusting the air pressure on the surface of the test liquid until the test liquid surface contacts the sealing plate.
