Description

Technical Field

[0001] This invention belongs to the field of PCR tube transfer technology, specifically relating to a PCR tube transfer tool. Background Technology

[0002] When performing PCR experiments, PCR tubes need to be placed on a PCR plate or ice box first, and then transferred to the PCR instrument one by one after the samples are added. This is a very time-consuming task. Moreover, many experiments have high requirements for temperature and time. If they are taken out and put in one by one, it is very likely that the influence of temperature and time cannot be avoided, which will affect the accuracy of the experiment.

[0003] Patent application number "CN202322099356.2" discloses a PCR tube transfer patch, including a plastic plate for PCR tube transfer. The top of the plastic plate has a double-sided adhesive film, and the top of the plastic plate also has a fixing component for connecting the double-sided adhesive film. The fixing component includes a connecting strap, which is located on the top of the plastic plate, with its top end contacting the bottom of the double-sided adhesive film. A fixing ring groove is formed on the top of the plastic plate. By bonding the double-sided adhesive film, PCR tubes placed on the PCR plate can be adhered to the plastic plate, allowing for the transfer of multiple PCR tubes at once, improving transfer efficiency. Furthermore, since the double-sided adhesive film is connected to the plastic plate via the connecting strap, which in turn is connected to the plastic plate via a fixing frame and fixing bolts, workers can disassemble the fixing bolts to remove and replace the worn-out connecting strap, reducing the wear rate of the plastic plate and lowering manufacturing costs.

[0004] The aforementioned patent achieves PCR tube transfer by using a detachable double-sided adhesive film. However, this double-sided adhesive film is a single unit, and in practical use, a portion is often unused, yet the entire unit must be disassembled for replacement, resulting in waste. Furthermore, its fixing method is relatively complex, requiring operators to go through multiple steps such as removing the fixing bolts, replacing the connecting strap, and then reinstalling the fixing bolts, making operation inconvenient and preventing rapid replacement.

[0016] Please see Figure 1-6 The present invention provides the following technical solution: a PCR tube transfer tool, including a main body 1, a handle 2 hinged to a groove on the side wall of the main body 1, a pressure block 3 and a strip 4, a plurality of setting grooves 11 provided on the top surface of the main body 1, a plurality of strips 4 corresponding to the setting grooves 11, a roll wound with the strips 4 rotatably disposed at one end of the setting grooves 11, the strips 4 being located inside the setting grooves 11, a plurality of adhesive layers 42 and friction layers 43 sequentially provided on the top surface of the strips 4, the part of the strips 4 with the friction layers 43 and the friction layers 43 having tear seams 41, a fixing block 12 provided on the opposite side walls at both ends of the setting grooves 11, and a pressure block 3 for fixing the strips 4 slidably mounted on the fixing block 12.

[0017] The handle 2 facilitates user gripping of the device. The handle 2 is hinged into a groove on the side wall of the main body 1. When the device is not in use, the handle 2 can be screwed into the groove, reducing the space required for storage. The adhesive layer 42 on the strip 4 is used to attach PCR tubes, facilitating user transfer. The pressure block 3 is used to fix the strip 4. When the strip 4 is fixed, the pressure block 3 presses against the friction layer 43. The rough surface of the friction layer 43 increases the friction between the strip 4 and the pressure block 3, ensuring the stability of the strip 4 during device use. The adhesive layer 42 and the friction layer 43 are located on the strip... The arrangement of the strips 4 is designed to ensure that when the adhesive layer 42 is located in the central working area of ​​the setting slot 11, the two pressure blocks 3 can press precisely on the friction layers 43 on both sides, thus ensuring reliable fixation. The main body 1 has multiple setting slots 11, with each strip 4 individually positioned inside one of them. When replacing the strip 4, the failed adhesive layer 42 can be replaced individually, reducing waste. The adhesive layer 42 has a protective layer; users can peel off the corresponding protective layer from the adhesive layer 42 according to the amount of PCR tubes that need to be moved, preventing unused adhesive layers 42 from being removed. The service life is affected. The strip 4 is wound on the drum. When the user replaces the adhesive layer 42, pulling the strip 4 will pull the used adhesive layer 42 away from the setting groove 11. As the strip 4 moves, the new adhesive layer 42 moves into the setting groove 11, making it convenient for the user to replace the adhesive layer 42. The tear slit 41 on the strip 4 makes it easy for the user to tear off the used adhesive layer 42, preventing the pulled-out strip 4 from affecting the use of the device. The pressure block 3 is slidably installed on the fixing block 12. The lower half of the side wall of the fixing block 12 is shaped as an outward inclined slope. The pressure block 3 is used for mounting and fixing. The bottom shape of the groove of block 12 is adapted to the bottom shape of the fixed block 12. When the user moves the pressure block 3 upward, the fixed block 12 moves to the lower half of the fixed block 12. At this time, the end face of the fixed block 12 separates from the inner side wall of the groove of the pressure block 3, and the pressure block 3 is released. When fixing the strip 4, the pressure block 3 is pressed down, and the fixed block 12 enters the upper half of the side wall groove of the pressure block 3. At this time, the end face of the fixed block 12 is attached to the side wall of the side wall groove of the pressure block 3. At this time, the pressure block 3 is fixed under the action of the friction between the fixed block 12 and the pressure block 3, ensuring the stability of the pressure block 3.

[0018] Specifically, the tear slit 41 is located in the middle section of the friction layer 43.

[0019] The position of the tear slit 41 is such that when the tear slit 41 is aligned with the edge of the setting groove 11, the position of the new adhesive layer 42 is the same as the original position of the used adhesive layer 42. This eliminates the need for the user to make fine adjustments to the position of the adhesive layer 42 while pulling the strip 4, thus improving the efficiency of the user in replacing the adhesive layer 42.

[0020] Specifically, a limiting frame 13 is provided on the bottom surface of the groove 11 away from the end of the drum on which the strip 4 is wound. The strip 4 passes through the limiting frame 13, and a groove that cooperates with the limiting frame 13 is provided on the bottom surface of the pressure block 3.

[0021] The limiting frame 13 serves as a limit, ensuring that the strip 4 remains in contact with the setting groove 11 during the pulling process. This allows the user to control the length of the strip 4 pulled out and prevents the tear seam 41 from not aligning with the edge of the setting groove 11 due to the strip 4 coming off the setting groove 11 during the pulling process.

[0022] Specifically, the top of the limiting frame 13 is a roller.

[0023] During the pulling process of the strip 4, the rollers set on the limit frame 13 will be rotated by the strip 4. The rotating rollers reduce the damage and friction of the strip 4 during the pulling process, making it easier for the user to pull the strip 4.

[0024] Specifically, the spool with the strip 4 wound around it is rotatably positioned at the end of the setting slot 11 opposite to the handle 2.

[0025] The position of the drum with strip 4 increases the amount of strip 4 that can be wound on the drum, reducing the frequency of drum replacement for the user.

[0026] Specifically, two handles 2 are hinged to the side wall of the main body 1. The two handles 2 are symmetrically arranged on the main body 1, and the handles 2 are equipped with telescopic structures.

[0027] The position of the hinge shaft of the handle 2 ensures that when the user unscrews the handle 2 from the slot where it is installed, the two handles 2 rotate in opposite directions. When the user moves the device, he / she needs to hold both handles 2 at the same time. The two handles 2 rotating in opposite directions can prevent the main body 1 and the handle 2 from rotating relative to each other during the user's movement of the device, thus ensuring the stability of the device. When the user moves the device, the length of the handle 2 can be adjusted to avoid the length of the handle 2 being inconvenient for the user to use the device. The telescopic structure is equipped with a locking mechanism, which can be fixed by a threaded push rod set on the handle 2.

[0028] Specifically, a fixing block 21 is installed on the top surface of the side wall groove of the main body 1 by means of a spring, and a groove that cooperates with the fixing block 21 is provided on the top surface of the handle 2.

[0029] The engagement of the fixing block 21 and its corresponding groove is used to fix the handle 2, ensuring the stability of the handle 2 after it is screwed into the side wall groove of the main body 1. The fixing block 21 is conical in shape, which ensures that the fixing block 21 can be smoothly pushed by the rotating handle 2. The spring on the fixing block 21 allows it to quickly return to its original position after being pushed, ensuring the working effect of the fixing block 21.

[0030] The working principle and usage process of this utility model are as follows: The handle 2 is unscrewed from the side wall groove of the main body 1, and the length of the handle 2 is adjusted. The PCR tube is then attached using the adhesive layer 42. At this time, the PCR tube attached to the adhesive layer 42 can be transferred using the moving device. When replacing the adhesive layer 42, the pressure block 3 is pushed up, releasing the fixation of the strip 4. The strip 4 with the adhesive layer 42 to be replaced is pulled, and the used adhesive layer 42 is pulled away from the setting groove 11. When the tear seam 41 is aligned with the edge of the setting groove 11, the pressure block 3 is pressed down, and the pressure block 3 is fixed by the fixing block 12. The strip 4 is fixed by the pressure block 3, and the strip 4 pulled out of the setting groove 11 is torn off through the tear seam 41.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
