During laboratory operation, transportation or storage, once an accidental drop occurs, the reaction cup without a drop-proof design is easily broken, causing the sample, reagent or reaction mixture contained therein to splash out, which not only causes the loss of experimental materials, but may also cause biological hazards and environmental pollution problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a drop-proof reaction cup for in vitro diagnostic reagent detection, comprising a cup body and an anti-drop mechanism arranged on the outside thereof:

[0006] The anti-fall mechanism includes a protective shell, and a first rubber plate and a second rubber plate are correspondingly arranged inside the protective shell. A plurality of telescopic parts are fixedly connected between the first rubber plate, the second rubber plate and the inner wall of the protective shell. Shock-absorbing pads are arranged on the inner walls of the first rubber plate and the second rubber plate, and the inner walls of the shock-absorbing pads are in contact with the surface of the cup body.

The air outlet ends on both sides of the micro air pump are connected with air pipes for transmitting the compressed air to the shunt pipe. The shunt pipe is fixedly connected to a plurality of transverse tubes on the opposite side. The tops of these transverse tubes are further fixedly connected to a plurality of vacuum suction cups. When the compressed air is released after passing through the transverse tubes, a local negative pressure area is formed under the transverse tubes, so that the vacuum suction cups can be firmly adsorbed on the bottom of the cup body, ensuring that the cup body is firmly fixed in the designated position, effectively preventing the risk of displacement or tipping of the cup body due to vibration, movement, etc., thereby further improving the safety and stability of the reaction cup for in vitro diagnostic reagent detection.

DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 5 , a drop-proof reaction cup for in vitro diagnostic reagent detection, comprising a cup body 1 and an anti-drop mechanism arranged on the outside thereof:

[0023] Furthermore, the anti-fall mechanism includes a protective shell 2, and a first rubber plate 3 and a second rubber plate 4 are correspondingly arranged inside the protective shell 2. A plurality of telescopic parts 5 are fixedly connected between the first rubber plate 3 and the second rubber plate 4 and the inner wall of the protective shell 2. Shock-absorbing pads 6 are arranged on the inner walls of the first rubber plate 3 and the second rubber plate 4, and the inner walls of the shock-absorbing pads 6 are in contact with the surface of the cup body 1.

[0024] First, a protective shell 2 is provided on the outside of the cup body 1. The protective shell 2 serves as the first layer of physical protection barrier, which can absorb and disperse the force brought by external impact and reduce the impact of direct impact on the cup body 1. The first rubber plate 3 and the second rubber plate 4 are respectively arranged inside the protective shell 2. The materials thereof have good elastic buffering performance. When the cup body 1 is impacted, the first rubber plate 3 and the second rubber plate 4 can be deformed to consume part of the impact energy and reduce the force transmitted to the cup body 1. The multiple telescopic parts 5 connected between the first rubber plate 3, the second rubber plate 4 and the inner wall of the protective shell 2 can perform telescopic movement when subjected to force, further absorbing and transforming the impact. The first rubber plate 3 and the second rubber plate 4 are fitted with a shock-absorbing pad 6 on their inner walls, which fits tightly to the cup body 1 and can provide stable support when the cup body 1 is shaken by force, and absorb the remaining vibration energy through its own high elasticity, effectively preventing the vibration from causing unnecessary disturbance to the reagents or samples in the cup body 1. The device improves the impact resistance of the reaction cup for in vitro diagnostic reagent detection in many aspects by setting an anti-fall mechanism, greatly reduces the risk of damage caused by accidental falling and various problems that may affect the accuracy of experimental results, and improves laboratory work efficiency and safety.

[0025] Furthermore, the telescopic member 5 includes a fixed sleeve 501 , and a movable rod 502 is slidably connected inside the fixed sleeve 501 . One end of the movable rod 502 extends to the outside of the fixed sleeve 501 and is fixedly connected to the surfaces of the first rubber plate 3 and the second rubber plate 4 .

[0026] Since one end of the movable rod 502 extends to the outside of the fixed sleeve 501 and is fixedly connected to the surfaces of the first rubber plate 3 and the second rubber plate 4, when the reaction cup is hit or vibrated, the movable rod 502 can shrink or stretch inside the fixed sleeve 501, and transmit and consume energy through its connection with the rubber plate, thereby achieving the effect of shock absorption and fall prevention.

[0027] Furthermore, one side of the fixing sleeve 501 is fixedly connected to the inner wall of the protective shell 2 , and a spring 503 is fixedly connected between the fixing sleeve 501 and the movable rod 502 .

[0028] Since the spring 503 is connected between the fixed sleeve 501 and the movable rod 502, and the movable rod 502 is fixedly connected to the surfaces of the first rubber plate 3 and the second rubber plate 4, the entire system forms a linkage shock-absorbing mechanism. Once an impact occurs, the spring 503, the movable rod 502 and the rubber plate will work together to absorb and disperse the impact force through the elastic properties of their respective materials, thereby achieving an excellent anti-fall effect.

[0029] Furthermore, a positioning groove is provided on one side of the first rubber plate 3 , and a positioning block is fixedly connected to one side of the second rubber plate 4 , and the positioning block and the positioning groove are clamped with each other.

[0030] When the reaction cup is impacted, the positioning block will be firmly embedded in the positioning groove to form a stable clamping structure, which not only strengthens the connection strength between the first rubber plate 3 and the second rubber plate 4, but also effectively prevents them from relative sliding under force, further improving the stability and reliability of the entire anti-fall mechanism.

[0031] Furthermore, a fixing mechanism is provided at the bottom of the inner wall of the protective shell 2, and the fixing mechanism includes a micro air pump 7. The air delivery end of the micro air pump 7 is fixedly connected to an air inlet pipe, one end of the air inlet pipe passes through the protective shell 2 and extends to the outside thereof, and the air outlet ends on both sides of the micro air pump 7 are fixedly connected to air delivery pipes 8.

[0032] Furthermore, one end of the gas supply pipe 8 is fixedly connected to a shunt pipe 9, the front and rear ends of the shunt pipe 9 are fixedly connected to the inner wall of the protective shell 2, the opposite side of the shunt pipe 9 is fixedly connected to a plurality of cross pipes 10, the top of the cross pipe 10 is fixedly connected to a plurality of vacuum suction cups 11, and the top of the vacuum suction cup 11 fits with the bottom of the cup body 1.

[0033] The micro air pump 7 arranged at the bottom of the inner wall of the protective shell 2 serves as a power source and can generate compressed air. The air outlet ends on both sides of the micro air pump 7 are connected with air pipes 8 for transmitting the compressed air to the shunt pipe 9. The shunt pipe 9 is fixedly connected to a plurality of transverse tubes 10 on the opposite side. The tops of these transverse tubes 10 are further fixedly connected to a plurality of vacuum suction cups 11. When the compressed air is released after passing through the transverse tubes 10, a local negative pressure area will be formed under the transverse tubes 10, so that the vacuum suction cups 11 can be firmly adsorbed on the bottom of the cup body 1, ensuring that the cup body 1 is firmly fixed in the designated position, effectively preventing the risk of displacement or tipping of the cup body 1 due to vibration, movement, etc., thereby further improving the safety and stability of the reaction cup for in vitro diagnostic reagent detection.

[0034] Furthermore, a handle 12 is fixedly connected to one side of the protective shell 2 .

[0035] The handle 12 allows the experimenter to grasp and carry the reaction cup containing in vitro diagnostic reagents more conveniently and safely, especially when processing samples, operating equipment or moving to different work areas, so as to avoid direct contact with the reaction cup that may contain biohazardous substances and reduce operational risks.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
