Description

Technical Field

[0001] The utility model relates to a disinfectant microorganism detection counter and belongs to the technical field of microorganism counting. Background Art

[0002] Disinfectant microbial testing is to evaluate the bactericidal effect by testing the microbial content in the disinfectant. The specific requirements are as follows:

[0003] ‌Disinfectant‌: Test once every quarter, the bacterial content must be less than 100 cfu / ml. A colony counter is needed for the detection of disinfectant microorganisms. The current colony counter includes a counter body, which is equipped with a circular colony pool. The culture dish is placed in the colony pool and counted through a magnifying glass. In order to accommodate a variety of culture dishes, the colony pool is designed to be larger. When placing a smaller culture dish, the culture dish is prone to slipping during counting, affecting the accuracy of the count. In addition, there is no protective device on the colony pool, so dust is easy to enter, which will also affect the accuracy of the count. Utility Model Content

[0004] The utility model provides a disinfectant microorganism detection counter to solve the problems in the above-mentioned background technology.

[0005] The utility model relates to a disinfectant microorganism detection counter, comprising a counter body, a colony pool being arranged on the counter body, a magnifying glass being arranged above the colony pool, a plurality of coaxial transparent support rings being arranged in sequence in the colony pool, the outer wall of the outermost support ring being in contact with the inner wall of the colony pool, a support retaining ring being fixed on the counter body outside the top of the colony pool, a rubber dust cover being buckled on the outer side of the support retaining ring, and a pressing boss being arranged at the bottom of the rubber dust cover and extending into the support retaining ring to press the top of the support ring.

[0006] As a preferred embodiment, a clamping groove is provided on the outer side of the top of the inner hole of each support ring, and a clamping protrusion that cooperates with the clamping groove is provided on the top outer side wall of the support ring except the outermost support ring. The clamping groove and the clamping protrusion are interference fit, which can better cooperate and fix with each other.

[0007] As a preferred embodiment, a support column is provided on the counter body outside the colony pool, a support sleeve is provided on the support column, a locking bolt is provided on the support sleeve, a mounting ring is fixed to the bottom of the support sleeve, a connecting rod is fixed to the outside of the mounting ring, and the other end of the connecting rod is fixedly connected to the magnifying glass, so that the up and down position of the magnifying glass can be conveniently adjusted for better focusing.

[0008] As a preferred embodiment, a guide boss is provided on the middle outer wall of the support column, and a guide groove matching the guide boss is provided in the inner hole of the support sleeve and the mounting ring. When the height of the magnifying glass is adjusted, the magnifying glass is always coaxial with the colony pool.

[0009] As a preferred embodiment, a mounting sleeve is inserted at the bottom of the support column, the mounting sleeve is fixed on the counter body, a square limiting groove is provided on the outer side of the top of the mounting sleeve, and a limiting platform that cooperates with the limiting groove is provided on the outer side wall of the lower end of the support column. The cooperation between the limiting platform and the limiting groove, and the cooperation between the guide groove and the guide boss, can quickly locate the center position of the magnifying glass, so that the axis of the magnifying glass is always coaxial with the colony pool.

[0010] The utility model has the following beneficial effects:

[0011] By arranging a plurality of coaxial transparent support rings which are sequentially sleeved in the colony pool, a suitable support ring can be selected according to the specifications of the culture dish to support and limit the culture dish to prevent the culture dish from sliding in the colony pool during counting, thereby affecting the counting accuracy. In addition, a support retaining ring and a rubber dust cover are provided. When not in use, the rubber dust cover can be closed on the support retaining ring to prevent dust from entering the colony pool and affecting the counting accuracy. In addition, after the rubber dust cover is closed, the pressing boss will press the top of the support ring to prevent the support ring from shaking and damaging the colony pool.
