Description

Pipe cover closing device for eight-pipe joint Technical Field The utility model relates to the technical field of medical equipment, in particular to a tube cover closing device for an eight-joint tube. Background In molecular biology experiments, PCR is a common experimental technique. PCR octant tubing is a common experimental consumable used to perform PCR reactions on multiple samples simultaneously. During the experiment, the tube cap of the eight-joint tube needs to be accurately covered on the tube body to prevent sample pollution and evaporation. At present, the traditional manual PCR eight-tube cover mode has low efficiency, and operators need to align the eight-tube covers to the eight-tube openings one by one to press and press. This operation not only consumes a lot of time and effort, but also during a long-term operation, the operator's hands are easily fatigued, resulting in uneven covering strength, possibly with the tube covering not being tightly covered or being askew, resulting in evaporation or contamination of the sample during amplification. The probability of specimen reproduction is increased, and the time for clinical patients to take reports is prolonged. In addition, when handling a large amount of samples, manual mode of covering can't satisfy quick, high-efficient experiment demand, has reduced whole experimental efficiency. It is therefore necessary to provide a tube cap closure device for an eight-way tube to solve the above-mentioned problems. Disclosure of utility model Based on the problems in the prior art, the embodiment of the application aims to provide a pipe cover closing device for an eight-joint pipe, which achieves the effect of convenient cover closing. The technical scheme adopted by the application for solving the technical problems is that the eight-joint pipe positioning device comprises an eight-joint pipe positioning plate, a positioning base and a pressing mechanism positioned above the eight-joint pipe positioning plate; the eight-joint tube placing plate is provided with placing holes for tightly fixing the PCR eight-joint tubes; the positioning base is provided with a track groove matched with the shape of the eight-connecting-pipe placing plate; The pressing mechanism comprises a pressing wheel and a pressing rod, the pressing wheel is horizontally arranged above the eight-connecting-tube placing plate, the pressing rods are fixedly connected to the two sides of the pressing wheel respectively, and the pressing rods are arranged at the notch of the fixing plate on the two sides of the positioning base and used for pushing the pressing wheel back and forth to achieve the pressing cover. Further, the placement hole is circular or approximately circular. Further, the placing holes are provided with 12 rows and eight rows A-H, and 96 placing holes are formed. Furthermore, the front of the positioning base is provided with two positioning sheets for ensuring the position fixing of the positioning sheets, and the positioning sheets cannot shake or displace in the process of covering the pipe cover. Further, a limiting block is arranged between the positioning base and the eight-joint pipe placing plate, so that the eight-joint pipe placing plate can be pulled out or pushed in and does not fall off. Furthermore, the elastic component is arranged below the lower pressure rod, a yielding interval is formed between the elastic component and the lower eight-joint pipe placing plate, and the eight-joint pipe placing plate is convenient to pull. The beneficial effects of the utility model are as follows: the pressing mechanism is utilized to press the pipe cover, so that the pipe cover of the eight-joint pipe is covered, the eight-joint pipe and the pipe cover can be evenly and quickly covered, deformation and breakage of the eight-joint pipe caused by overlarge cover force or gap generated by the incomplete covering are prevented, evaporation or pollution of liquid occurs in amplification, the detection period of a sample is prolonged, the time of taking a report by a patient is prolonged, and inconvenience is brought to the operation of post personnel.
