[0002] A sulfuric acid sampling bottle is a container designed specifically for storing corrosive chemicals such as sulfuric acid. This sampling bottle is usually made of corrosion-resistant materials such as glass or high-density polyethylene (HDPE) to ensure the safety of chemicals.

[0003] When sampling the sulfuric acid in the sulfuric acid sampling bottle, it is usually necessary to open the bottle cap, and then insert the straw from the bottle mouth into the bottle body. Since sulfuric acid cannot be exposed to the air for a long time, after sampling, the bottle cap needs to be tightened quickly. The above operations need to be completed in a short time, which will cause the operator to be in a hurry, the operation is cumbersome, and there is even a risk of knocking over the sulfuric acid sampling bottle. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sulfuric acid sampling bottle for sulfuric acid production from sulfur, aiming to solve the problems that when sampling sulfuric acid, the operator is in a hurry, the operation is cumbersome, and there is even a risk of knocking over the sulfuric acid sampling bottle.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: providing a sulfuric acid sampling bottle for sulfuric acid production from sulfur, including a bottle body and a bottle cap. The bottle cap is installed on the bottle mouth of the bottle body. A sampling port is opened in the middle of the bottle cap. A sealing mechanism is arranged on the lower end surface of the bottle cap. The sealing mechanism includes a rotating shaft, a blocking plate and a counterweight. The rotating shaft is axially rotatably arranged on one side of the sampling port. A first connecting rod is arranged on the side of the rotating shaft close to the sampling port. The blocking plate is arranged at the end of the first connecting rod. A second connecting rod is arranged on the side of the rotating shaft far from the sampling port. The counterweight is arranged at the end of the second connecting rod. The included angle between the first connecting rod and the second connecting rod is 90° - 150°. The blocking plate fits on the lower end surface of the bottle cap under the action of the gravity of the counterweight to block the sampling port.

[0006] In a possible implementation, the inner diameter of the sampling port decreases successively from top to bottom. A sealing plug is arranged in the sampling port and the upper end of the sealing plug protrudes above the upper end surface of the bottle cap.

[0007] In a possible implementation, an arc-shaped concave part is arranged on the upper end surface of the sealing plug, and a transverse convex rib is arranged in the middle of the arc-shaped concave part.

[0008] In a possible implementation, a sunk groove is opened on the lower end surface of the bottle cap. The outer contour of the sunk groove is adapted to the outer contour of the blocking plate, and the lower end of the sampling port communicates with the sunk groove.

[0009] In a possible implementation, the cross-section of the sinking groove decreases successively from bottom to top, the cross-section of the sealing plate decreases successively from bottom to top, and there is a clearance between the edge of the sinking groove and the edge of the sealing plate.

[0010] In a possible implementation, the sampling port is located on the side of the sinking groove away from the rotating shaft.

[0011] In a possible implementation, two connecting sleeves are coaxially and spacedly arranged on the lower end surface of the bottle cap. Both of the two connecting sleeves are located on the same side of the sampling port. The two ends of the rotating shaft respectively penetrate into the two connecting sleeves and are rotationally arranged axially. The first connecting rod and the second connecting rod are respectively connected to the part of the rotating shaft between the two connecting sleeves.

[0012] In a possible implementation, the counterweight is a counterweight cylinder. The counterweight cylinder is connected to the end of the second connecting rod and the axis of the counterweight cylinder is perpendicular to the axis of the second connecting rod.

[0013] In a possible implementation, an internal thread sleeve is arranged on the lower end surface of the bottle cap. The internal thread sleeve is threadedly connected to the inner side of the bottle mouth. The outer extension of the bottle cap is provided with a downwardly bent flange. A sealing groove is formed between the internal thread sleeve and the flange.

[0014] The beneficial effect of a sulfuric acid sampling bottle for sulfuric acid production provided by the present utility model is as follows: Compared with the prior art, when the sulfuric acid sampling bottle stores sulfuric acid, the bottle cap is installed on the bottle mouth of the bottle body. Since the angle between the first connecting rod connecting the sealing plate and the second connecting rod connecting the counterweight is 90° - 150°, that is, greater than a right angle and less than a flat angle. Under the action of its own weight, the end of the second connecting rod is in a sinking state. The rotating shaft rotates with its axis as the rotation axis, and the first connecting rod drives the sealing plate to rotate upward, so that the upper end surface of the sealing plate fits against the lower end surface of the bottle cap, and the sealing plate seals the lower port of the sampling port, so that the sulfuric acid in the sulfuric acid sampling bottle is sealed inside. When sampling is required, the straw is inserted into the sampling port from top to bottom. The lower end of the straw presses the sealing plate downward. The sealing plate drives the rotating shaft to rotate reversely with its axis as the rotation axis through the first connecting rod, so that the sealing plate rotates away from the sampling port, and thus drives the counterweight to rotate upward against gravity through the second connecting rod. As the sealing plate rotates away from the sampling port, the sealing plate no longer blocks the straw, and the straw is inserted into the inner cavity of the bottle body to suck sulfuric acid. When the straw finishes sucking sulfuric acid, it is withdrawn from the sampling port, and the sealing plate is reset under the action of the counterweight and blocks the sampling port again. A sulfuric acid sampling bottle for sulfuric acid production provided by the present utility model can realize the storage of sulfuric acid in the sampling bottle, and when sampling with a straw, the operation is safer and more convenient.

[0025] Please refer to Figures 1 to 5 , and a sulfuric acid sampling bottle for sulfuric acid production will be described below. A sulfuric acid sampling bottle for sulfuric acid production includes a bottle body 1 and a bottle cap 2. The bottle cap 2 is installed on the bottle mouth of the bottle body 1. A sampling port 3 is provided in the middle of the bottle cap 2. A sealing mechanism is provided on the lower end surface of the bottle cap 2. The sealing mechanism includes a rotating shaft 4, a blocking plate 5 and a counterweight 6. The rotating shaft 4 is axially rotatably arranged on one side of the sampling port 3. A first connecting rod 7 is provided on the side of the rotating shaft 4 close to the sampling port 3. The blocking plate 5 is arranged at the end of the first connecting rod 7. A second connecting rod 8 is provided on the side of the rotating shaft 4 away from the sampling port 3. The counterweight 6 is arranged at the end of the second connecting rod 8. The included angle between the first connecting rod 7 and the second connecting rod 8 is 90° - 150°. The blocking plate 5 fits on the lower end surface of the bottle cap 2 under the action of the gravity of the counterweight 6 to block the sampling port 3.

[0026] A sulfuric acid sampling bottle for sulfuric acid production provided by the utility model, compared with the prior art, when the sulfuric acid sampling bottle stores sulfuric acid, the bottle cap 2 is installed on the bottle mouth of the bottle body 1. Since the angle between the first connecting rod 7 connecting the sealing plate 5 and the second connecting rod 8 connecting the counterweight 6 is 90° - 150°, that is, greater than a right angle and less than a flat angle. Under the action of its own weight, the end of the second connecting rod 8 is in a sunken state. With the rotation axis 4 as the rotation axis, the first connecting rod 7 drives the sealing plate 5 to rotate upward, so that the upper end surface of the sealing plate 5 fits against the lower end surface of the bottle cap 2, and the sealing plate 5 seals the lower port of the sampling port 3, so that the sulfuric acid in the sulfuric acid sampling bottle is sealed inside. When sampling is required, the straw is inserted into the sampling port 3 from top to bottom, and the lower end of the straw presses the sealing plate 5 downward. The sealing plate 5 drives the rotation axis 4 to rotate reversely with its axis as the rotation axis through the first connecting rod 7, so that the sealing plate 5 rotates to the side away from the sampling port 3, and thus drives the counterweight 6 to rotate upward against gravity through the second connecting rod 8. As the sealing plate 5 rotates to the side away from the sampling port 3, the sealing plate 5 no longer blocks the straw, and the straw is inserted into the inner cavity of the bottle body 1 to suck sulfuric acid. When the straw finishes sucking sulfuric acid, it is withdrawn from the sampling port 3, and the sealing plate 5 is reset under the action of the counterweight 6 and seals the sampling port 3 again. A sulfuric acid sampling bottle for sulfuric acid production provided by the utility model can realize the storage of sulfuric acid in the sampling bottle, and when sampling with a straw, the operation is safer and more convenient.

[0027] Please refer to Figure 2 and Figure 3 , the inner diameter of the sampling port 3 decreases sequentially from top to bottom. A sealing plug 9 is arranged in the sampling port 3, and the upper end of the sealing plug 9 protrudes above the upper end surface of the bottle cap 2. The sealing plug 9 can be inserted into the sampling port 3 in a non-sampling state, improving the sealing performance of the sampling bottle. When sampling is required, the part of the upper end of the sealing plug 9 that protrudes above the upper end surface of the bottle cap 2 can be held to conveniently remove the sealing plug 9.

[0028] Preferably, the upper end surface of the sealing plug 9 is provided with an arc-shaped concave part, and a transverse convex rib 10 is arranged in the middle of the arc-shaped concave part. When it is necessary to remove the sealing plug 9, the transverse convex rib 10 can also be held for operation.

[0029] Please refer to Figure 2 and Figure 4 , a sink 11 is formed on the lower end surface of the bottle cap 2. The outer contour of the sink 11 is adapted to the outer contour of the sealing plate 5, and the lower end of the sampling port 3 communicates with the sink 11. In a non-loaded state, the sealing plate 5 sinks into the above-mentioned sink 11, so as to achieve a better sealing effect on the sampling port 3.

[0030] Among them, the cross-section of the sinking groove 11 gradually decreases from bottom to top, and the cross-section of the sealing plate 5 also gradually decreases from bottom to top. The sinking groove 11 and the sealing plate 5 are both conical matching groove and plate structures. There is a clearance gap 12 between the edge of the sinking groove 11 and the edge of the sealing plate 5 to prevent the edge of the sealing plate 5 from interfering with the edge of the sinking groove 11 when the sealing plate 5 enters or leaves the sinking groove 11.

[0031] Specifically, the sampling port 3 is located on the side of the sinking groove 11 away from the rotating shaft 4. When the sealing plate 5 rotates through a small angle, the sealing plate 5 can avoid the sampling port 3 in the vertical direction, facilitating the smooth insertion of the straw into the bottle body 1.

[0032] Two connecting sleeves 13 are coaxially and spacedly arranged on the lower end surface of the bottle cap 2. Both of the two connecting sleeves 13 are located on the same side of the sampling port 3, and the two connecting sleeves 13 are integrally formed on the lower end surface of the bottle cap 2. Both ends of the rotating shaft 4 pass through the two connecting sleeves 13 and are axially rotatably arranged. In order to prevent the rotating shaft 4 from disengaging from the connecting sleeve 13, both ends of the rotating shaft 4 pass through the connecting sleeve 13 and are axially penetrated with limit pins, which can also prevent the rotating shaft 4 from axially rotating. Among them, the first connecting rod 7 and the second connecting rod 8 are respectively connected to the part of the rotating shaft 4 between the two connecting sleeves 13.

[0033] Specifically, the counterweight 6 is a counterweight cylinder, which is connected to the end of the second connecting rod 8 and the axial direction of the counterweight cylinder is perpendicular to the axial direction of the second connecting rod 8. The size of the counterweight cylinder can be determined with reference to the size of the space at the bottom of the bottle cap 2. At the same time, it is necessary to ensure that the self-weight of the counterweight cylinder can make the sealing plate 5 fit against the lower end surface of the bottle cap 2, which is not limited here.

[0034] Please refer to Figure 2 , an internal thread sleeve 14 is arranged on the lower end surface of the bottle cap 2. The internal thread sleeve 14 is threadedly connected to the inner side of the bottle mouth. The outer extension of the bottle cap 2 is provided with a downwardly bent flange 15. A sealing groove 16 is formed between the internal thread sleeve 14 and the flange 15. A double seal is formed between the circumference of the bottle cap 2 and the bottle mouth, so as to achieve a better sealing effect on sulfuric acid.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
