Description

Technical Field

[0001] This utility model relates to the field of PCR tube storage technology, and in particular to a PCR tube storage device. Background Technology

[0002] PCR tubes are laboratory consumables used for polymerase chain reactions and are usually made of plastic. PCR tube storage devices are specially designed laboratory equipment for the safe and orderly storage and management of PCR tubes to reduce the probability of PCR tubes being damaged or contaminated.

[0003] Patent specification CN220948997U discloses a PCR tube storage device, including a storage box and a storage mechanism disposed inside the storage box. The storage mechanism includes a working component and a sliding component. The working component includes a storage plate, a group of tube wells, a PCR tube body, and a tube cap. The storage box contains a storage plate with a group of tube wells inside. The inner wall of the group of tube wells is fitted with the PCR tube body. The device, by setting up a storage plate, a group of tube wells, a PCR tube body, a tube cap, a connecting block, a handle, a connecting groove block, and a locking block, allows the tube cap to be installed onto the PCR tube body and then inserted into the group of tube wells. The storage plate can be connected to the storage box through the locking block engaging with the groove on the connecting groove block. The storage plate can be pulled out by pulling the handle, making it easy to pick up and put down. By setting multiple groups of storage plates, the PCR tube bodies can be grouped for processing, enabling rapid location of the required sample and shortening the search time.

[0004] However, in implementing the relevant technology, the above-mentioned PCR tube storage device has the following problems: the device limits the PCR tube body by means of the tube hole group, making it difficult for the PCR tube body to move horizontally, but the limiting effect on the PCR tube body in the vertical direction is poor. When the storage plate is moved too fast or the storage plate is hit, the PCR tube body is prone to shaking up and down in the tube hole group, which increases the probability of loosening between the tube cap and the PCR tube body, and easily leads to leakage of the sample stored in the PCR tube body, thereby reducing the stability of the device during use. In view of this, a PCR tube storage device is provided to overcome the above defects. Utility Model Content

[0009] As a further description of the above technical solution: two limiting holes are provided on one side of the storage plate, and the interior of the two limiting holes respectively fits into the side of the two limiting rods, so that the storage plate can be fixedly placed.

[0010] As a further description of the above technical solution: the interior of each of the two limiting boxes is provided with a connecting groove, and the interior of the two connecting grooves is slidably connected to the side of the two connecting blocks respectively, so that the connecting blocks can be used to fix the limiting rod.

[0011] As a further description of the above technical solution: one side of each of the two reset springs is fixedly connected to one side of each of the two connecting blocks, and the other side of each of the two reset springs is fixedly connected to the inside of each of the two limiting boxes, so that the reset springs can easily squeeze the connecting blocks.

[0014] This utility model has the following beneficial effects:

[0015] This invention relates to a PCR tube storage device. Through its design, a placement plate effectively limits the position of the PCR tube body, preventing horizontal movement. Two pressure plates further limit the position of the cover and connecting plate, preventing them from moving and thus hindering vertical movement of the PCR tube body. When retrieving the PCR tube body, the pull rings and limiting rods move backward, disengaging the limiting rods from the storage plate. A torsion spring then rotates the two pressure plates upward, opening the top of the storage plate for easy access to the PCR tube body. After retrieval, the two pull rings are moved, thereby engaging two teeth... The racks move away from each other, causing the two gears and two rotating rods to reverse, which in turn causes the two pressure plates to rotate downwards. This pressure plates press against the connecting plate and the cover plate, thus limiting the position of the PCR tube body. Releasing the pull ring pushes the connecting block and the limiting rod forward through the return spring, causing the limiting rod to enter the corresponding limiting hole in the storage plate. This limits the position of the movable plate and the rack, and thus the gears, rotating rods, and pressure plates. This allows the device to improve the stability of the PCR tube body during placement without affecting the efficiency of storing and retrieving the PCR tube body, reducing the probability of leakage and improving the stability of the device during use.

[0030] Working principle:

[0031] When using this invention, the placement hole in the placement plate 2 facilitates the positioning of the PCR tube body 3, making it difficult for the PCR tube body 3 to move horizontally. Two pressure plates 9 limit the cover plate 5 and the connecting plate 4, preventing them from moving and thus making it difficult for the PCR tube body 3 to move vertically, thereby improving the stability of the PCR tube body 3 during placement. When it is necessary to access the PCR tube body 3, pull the two pull rings 17, causing the pull rings 17 and the limiting rod 16 to move backward, disengaging the limiting rod 16 from the storage plate 1. At this time, the movable plate 1... 2. When the limit switch is lost, the torsion spring 8 drives the two pressure plates 9 to rotate upwards, thereby driving the two rotating rods 7 and the two gears 10 to rotate, which in turn drives the two racks 13 to move closer together, which in turn drives the two movable plates 12 to move closer together, which in turn drives the two pull rings 17 to move closer together. At this time, the top of the storage plate 1 is open. Moving the connecting plate 4 and the cover plate 5 upwards allows the corresponding PCR tube body 3 to be taken out. Moving the connecting plate 4 and the cover plate 5 downwards allows the PCR tube body 3 to be placed into the storage plate 2. After the PCR tube body 3 is stored and retrieved, the two pull rings 17 are moved, thereby driving the two pull rings 17 to move closer together. The two limit rods 16 move away from each other, which in turn moves the two movable plates 12 away from each other, which in turn moves the two racks 13 away from each other, which in turn moves the two gears 10 in reverse, which in turn moves the two rotating rods 7 in reverse, which in turn moves the two pressure plates 9 downward, causing the pressure plates 9 to press against the connecting plate 4 and the cover plate 5, thereby limiting the PCR tube body 3. Releasing the pull ring 17, the return spring 18 pushes the connecting block 15 and the limit rods 16 forward, causing the limit rods 16 to enter the corresponding limiting holes in the storage plate 1, thereby allowing the movable plates 12 and the racks 13 to move away from each other. Strip 13 is limited, thereby limiting gear 10, rotating rod 7 and pressure plate 9. Pulling pull ring 17 and moving the two pull rings 17 closer together will move pressure plate 9 upward. Moving the two pull rings 17 away and releasing pull ring 17 will move pressure plate 9 downward and limit it. This makes pressure plate 9 easy to adjust quickly and will not affect the storage and retrieval of PCR tube body 3. Thus, without affecting the storage and retrieval efficiency of PCR tube body 3, this device can improve the stability of PCR tube body 3 when placed, reduce the probability of leakage of PCR tube body 3, and thus improve the stability of the device during use.
