Description

Technical Field

[0001] The utility model relates to the field of Karl Fischer reagents, in particular to a Karl Fischer reagent mixing device. Background Art

[0002] The existing patent (publication number: CN215476506U) proposes a Karl Fischer reagent storage box, including a box body, wherein pull plates are fixedly arranged on all sides of the interior of the box body, a pull ring is fixedly arranged on the outer upper end of the pull plate on the side away from the box body, a top plate is fixedly arranged on the outer lower end of the pull plate close to the box body, a hinge is fixedly arranged on the outer lower end of the pull plate, the hinge is fixedly connected to the box body, a placement groove is opened inside the box body, a fixed rotating shaft is fixedly arranged at the bottom end of the placement groove, and a clamping block is fixedly arranged on the outer top of the fixed rotating shaft. However, this device "can slide the reagent tube into the clamping ring until it is fixed between the inside of the clamping ring opened by the clamping block" connects the clamping block and the clamping ring through the reagent tube. When the test tube is taken out, the clamping block and the clamping ring lose linkage, making it difficult to close the pull plate when the test tube is lost, affecting the convenience of use. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a Karl Fischer reagent dispensing device, which can drive the upper linkage rod to be pressed down by opening the sealing cover, and at the same time, drives the upper linkage rod to rotate through the transition connection block and the lower linkage rod connection mechanism, thereby driving the driven rack and the lifting bearing block to move upward as a whole, so that the lifting bearing platform can synchronously hold up all the reagent storage tubes, so that all the reagent storage tubes are pushed out, which is convenient for operators to use; on the contrary, when the sealing cover is closed, all the reagent storage tubes are synchronously lowered, and the storage of the prepared reagent storage tubes is completed. The reagents can be taken and prepared in batches at the same time, and the taking and storage process is convenient.

Beneficial Effects

[0008] 1. When the utility model is used to prepare Karl Fischer reagent, when the sealing cover is opened to drive the upper linkage rod to be pressed down, the upper linkage rod drives the lifting driving gear to rotate through the transition connection block and the lower linkage rod connection mechanism, thereby driving the driven rack and the lifting bearing block to move upward as a whole, so that the lifting bearing platform can synchronously lift all reagent storage tubes, so that all reagent storage tubes are ejected, which is convenient for operators to take and prepare. On the contrary, when the sealing cover is closed, all reagent storage tubes are synchronously lowered to complete the storage of the prepared reagent storage tubes. The reagents can be taken and prepared in batches at the same time, and the taking and storage process is convenient.

[0009] 2. The delayed lifting rod of the utility model slides inside the delayed lifting slot, so that the sealing cover is opened to a certain angle and the driven rack is driven to a certain height before the lifting bearing block can be driven to lift, thereby ensuring that the opening and closing process of the sealing cover and the lifting and lowering process of the reagent storage tube will not interfere with each other.

[0010] 3. In the utility model, the distance between the lower linkage column and the central axis of the lifting drive gear is smaller than the radius of the lifting drive gear, and the lifting drive gear drives the driven rack to rise by a distance greater than the lowering distance when the lower linkage rod drives the lifting drive gear to rotate, so that the device can achieve a larger reagent storage tube lifting effect by relying only on a smaller displacement change caused by lifting the sealing cover, so that a larger portion of the upper part of the reagent storage tube is exposed to the outside, further facilitating the operation of taking the reagent storage tube during preparation.

[0011] 4. The rubber bearing block of the utility model is made of a relatively soft material, which prevents the operator from letting go of the reagent storage tube too early after mixing and causing the reagent storage tube to fall and be damaged, thereby ensuring the safety of the reagent storage tube storage process.
