[0025] A limiting block matched with the locking piece is arranged at the opening of the bottle body.

[0026] Furthermore, one end of the locking member extends outside the connecting block.

[0027] Furthermore, the locking member comprises:

[0028] a first connecting portion;

[0029] A second connecting portion, fixedly disposed on one end of the first connecting portion;

[0030] A clamping portion, fixedly disposed on the second connecting portion;

[0031] The clamping portion and the limiting block are clamped with each other.

[0032] Furthermore, one end of the clamping portion is configured as a first inclined surface, and one end of the limiting block is configured as a second inclined surface matching the first inclined surface.

[0033] Furthermore, the first connecting portion and the second connecting portion are arranged perpendicular to each other.

[0034] Furthermore, the material taking component also includes:

[0035] The extension tube is sleeved on one end of the catheter.

[0036] Furthermore, one end of the extension tube away from the liquid guiding tube is configured as a tapered portion.

[0037] The beneficial effect of the present application is that it provides a reagent bottle for quantitative liquid extraction in a controlled quantity laboratory. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0053] Reference Figure 1-5A reagent bottle for quantitative liquid collection in a laboratory comprises a bottle body 1, a bottle cap 2 and a material collection component 3; the bottle cap 2 is connected to the bottle body 1 by threads, the interior of the bottle body 1 is hollowed out and an opening 4 is provided at the upper end of the bottle body 1, and the material collection component 3 is arranged on the bottle cap 2. The material taking component 3 includes a connecting block 5, a push rod 6, a connecting rod 7, a pull plate 8, a liquid guide tube 9, and a liquid outlet tube 10; the connecting block 5 is abutted against the bottle cap 2, and a receiving chamber 11 is opened inside the connecting block 5; the push rod 6 is slidably arranged in the receiving chamber 11, the connecting rod 7 is fixedly arranged on the push rod 6, one end of which extends to the outside of the connecting block 5 and is sealed and slidably matched with the connecting block 5; the pull plate 8 is fixedly arranged on one end of the connecting plate, the liquid guide tube 9 is arranged at the bottom of the connecting block 5, and one end of the liquid guide tube 9 is connected with the receiving chamber 11, and the other end passes through the bottle cap 2 and extends to the inside of the bottle body 1, and is connected with the inside of the bottle body 1; the liquid outlet tube 10 is arranged on one end of the connecting block 5 and is connected with the receiving chamber 11; a first one-way valve is provided on the liquid outlet tube 10 for flowing the reagent from the receiving chamber 11 into the liquid outlet tube 10 and then out, and a second one-way valve is provided on the liquid guide tube 9 for introducing the reagent in the bottle body 1 into the receiving chamber 11. When the reagent in the bottle 1 needs to be taken out, the pull plate 8 is pulled upward, and the pull plate 8 drives the push rod 6 to move upward together through the connecting rod 7, thereby changing the air pressure inside the accommodating chamber 11 and the air pressure inside the bottle 1 at the same time, so that the reagent in the bottle 1 flows into the accommodating chamber 11 through the liquid guide tube 9, and then the pull plate 8 is pressed downward to move the push rod 6 downward, so that the reagent in the accommodating chamber 11 is squeezed into the liquid outlet pipe 10, and then flows out from the liquid outlet pipe 10. Thus, the amount of the reagent can be well controlled. Under the action of the first one-way valve and the second one-way valve, the reagent enters the accommodating chamber 11 through the first one-way valve, and at this time, due to the insufficient pressure inside the accommodating chamber 11, the reagent will not flow out from the second one-way valve, and will only flow out from the second one-way valve to the liquid outlet pipe 10 when the push rod 6 is pressed downward.

[0054] One end of the liquid outlet tube 10 is provided with a bendable extension tube, so as to facilitate dripping the reagent onto the test paper.

The connecting block 5 is fixed to the bottle cap 2 by the cooperation of the locking member 13 and the limit block 17. When the connecting block 5 needs to be disassembled, the locking member 13 is pressed in the length direction of the groove 15, so that one end of the locking member 13 is separated from the limit block 17, thereby facilitating the disassembly of the connecting block 5.

[0058] The locking member 13 includes a first connecting portion 18, a second connecting portion 19, and a clamping portion 20; the second connecting portion 19 is fixedly arranged on one end of the first connecting portion 18, the clamping portion 20 is fixedly arranged on the second connecting portion 19, and the clamping portion 20 is mutually clamped with the limit block 17. The first connecting portion 18 and the second connecting portion 19 are arranged perpendicular to each other, and the first connecting portion 18, the second connecting portion 19, and the clamping portion 20 are an integrally formed structure.
