Abstract
Description
Technical Field
[0001] This utility model relates to the field of gene amplification instrument technology, and in particular to a gene amplification instrument that is easy to remove from the test tube. Background Technology
[0002] A gene amplification instrument is a device that uses PCR technology to amplify specific DNA and is widely used in medical and biological laboratories.
[0003] The heating module of the gene amplification instrument has multiple test tube sockets arranged in a matrix. During experiments, staff need to insert multiple rows of test tubes into these sockets. Staff typically arrange the rows with one column between them, leaving space for fingers to insert and easily remove the sample tubes. However, this results in a limited number of test tubes per experiment, leading to low efficiency. To improve efficiency, the test tube sockets should be filled tightly, which makes it difficult for staff to remove the tubes. Utility Model Content

[0035] Reference Figures 1 to 7 A gene amplification instrument that allows easy removal of test tubes includes: a body 100, a heating module 200, an up-and-down lifting structure 300, and a lifting drive structure 400.
[0036] The machine body 100 has a test tank 110.
[0037] The main body 100 is connected to a slot cover 120, which is hinged to the main body 100. The slot cover 120 is used to seal the test slot 110 to prevent heat loss from the test slot 110 and to prevent burns caused by accidental hand insertion into the test slot 110 during the operation of the gene amplification instrument.
[0038] The heating module 200 includes a heating metal block and a heating structure for heating the test tube. The heating structure is used to heat the heating metal block, and is a commonly used heating structure in the art; its specific construction will not be described in detail here. The heating metal block is an aluminum component; in other embodiments, other metal materials may also be used. Those skilled in the art can select the specific material of the heating metal block according to actual needs.
[0039] The heating metal block has multiple test tube insertion holes 210 arranged in a matrix of multiple rows and columns. The test tube insertion holes 210 are used to insert and fix test tubes. The inner wall of the test tube insertion hole 210 is in contact with the outer circumferential surface of the test tube to achieve heat transfer and heat the sample inside the test tube. Specifically, in this embodiment, the test tubes adopt an integral structure of multiple test tubes connected in a row. In other embodiments, the test tubes can also be set as independent structures for each test tube.
[0040] Specifically, in this embodiment, a receiving groove 220 is provided on the upper end surface of the heated metal block. The receiving groove 220 is used to accommodate the vertical lifting structure 300. The number of receiving grooves 220 is set to be multiple, and the multiple receiving grooves 220 are arranged one-to-one with the multiple rows of test tube insertion holes 210.
[0041] The number of vertical lifting structures 300 is set to multiple, and the multiple vertical lifting structures 300 are set one-to-one with the multiple rows of test tube insertion holes 210. The vertical lifting structures 300 are installed in the receiving groove 220. The vertical lifting structures 300 are heat-conducting components. Specifically, the vertical lifting structures 300 are made of aluminum components.
[0042] The end of the lifting structure 300 is provided with a second sliding shaft 310.
[0043] Specifically, in this embodiment, the vertical lifting structure 300 has multiple lifting holes 320, and the multiple lifting holes 320 are configured to correspond one-to-one with the test tube insertion holes 210.
[0044] Specifically, in this embodiment, an upper and lower guide assembly 500 is provided between the upper and lower lifting structure 300 and the body 100. The upper and lower guide assembly 500 includes an upper and lower guide block 510 and an upper and lower guide slide rail 520. The upper and lower guide slide rail 520 is fixedly installed on the body 100 and extends in the upper and lower direction. The upper and lower guide block 510 is fixedly connected to the upper and lower lifting structure 300 and slidably connected to the upper and lower guide slide rail 520. By providing the upper and lower guide assembly 500, the sliding path of the upper and lower lifting structure 300 can be guaranteed, thereby preventing the upper and lower lifting structure 300 from tilting.
[0045] Specifically, the lifting drive structure 400 includes: a control structure 410, a first control element 420, a second control element 430, and a damping element 440. Specifically, in this embodiment, two second control elements 430 are provided, respectively disposed on the front and rear sides of the lifting structure 300, and fixedly connected by a connecting rod. In other embodiments, only one second control element 430 may be provided; those skilled in the art can select the number of second control elements 430 according to actual needs.
[0046] The first control component 420 is slidably mounted on the body 100, and the first control component 420 is slidably connected to the body 100 in the vertical direction. The upper end of the first control component 420 is designated as the first control end, and the lower end of the first control component 420 is designated as the first connection end. The first control component 420 is fixed with a first sliding shaft 421.
[0047] The first control end is used to abut against the slot cover 120. When the slot cover 120 abuts against the first control end, during the process of the slot cover 120 continuing to close, the first control member 420 will move downward because the first control end abuts against the slot cover 120.
[0048] The second control member 430 is provided with a second hinge portion and a second connecting portion. The second hinge portion is the end of the second control member 430.
[0049] The second hinge is hinged to the body 100.
[0050] The second connecting part is provided with a first sliding groove 431, and a first sliding shaft 421 is disposed in the first sliding groove 431. The first sliding shaft 421 is slidably connected to the first sliding groove 431, and the first sliding shaft 421 can rotate in the first sliding groove 431 so that the first control member 420 and the second control member 430 can slide relative to each other and be hinged.
[0051] The second control member 430 has a second sliding groove 432 in the middle. The second sliding shaft 310 is disposed in the second sliding groove 432. The second sliding shaft 310 is slidably connected to the second sliding groove 432, and the second sliding shaft 310 can rotate in the second sliding groove 432 so that the lifting structure 300 and the second control member 430 can slide relative to each other and be hinged.
[0052] A control structure 410 is disposed between the first control member 420 and the body 100, and is used to drive the first control member 420 to move upward. Specifically, in this embodiment, the control structure 410 is configured as an elastic member, more specifically, as a spring structure. Both ends of the control structure 410 abut against the body 100 and the first control member 420, respectively. When the first control member 420 moves downward, it compresses the control structure 410, allowing the control structure 410 to retain its elastic potential energy. In other embodiments, the control structure 410 can also be configured as a spring or other elastic structure. Those skilled in the art can select the specific construction of the control structure 410 according to actual needs.
[0053] The damping element 440 is disposed between the first control element 420 and the body 100. The two ends of the damping element 440 are connected to the first control element 420 and the body 100 respectively. By setting the damping element 440, the rising speed of the first control element 420 can be prevented from being too fast, thereby preventing the test tube from being driven by the vertical lifting structure 300 to quickly detach from the vertical lifting structure 300, thus preventing the test tube from flying out and falling, and effectively protecting the test tube.
[0054] When the tank cover 120 flips upward, the control structure 410 drives the first control component 420 to rise. The first sliding shaft 421 drives the second connecting part of the second control component 430 to rise. Since the second hinge part is hinged to the machine body 100, the second control component 430 will tilt, thereby causing multiple lifting structures 300 to be arranged in a stepped manner. During the upward movement of the lifting structures 300, the test tubes will rise, thus arranging multiple rows of test tubes in a stepped manner. This arrangement makes it easier for staff to remove the test tubes even when they are closely arranged.
[0055] Specifically, in this embodiment, a replacement contact head 422 is installed on the first control terminal. The replacement contact head 422 is detachably connected to the first control terminal. Specifically, the replacement contact head 422 is detachably connected to the first control terminal through a threaded structure.
[0056] During prolonged use, the replacement contact head 422 may wear out. In this case, the old replacement contact head 422 can be removed and replaced with a new one, thus ensuring that the vertical lifting structure 300 of the gene amplification instrument can continue to be used normally. This avoids the overall length of the first control component 420 being shortened due to wear of the replacement contact head 422, thereby preventing the second control component 430 from being unable to be horizontal when the tank cover 120 is fully closed, which would result in a slight height difference between the multiple vertical lifting structures 300. This also avoids uneven heating of multiple rows of test tubes, which is beneficial to ensuring the effectiveness of the gene amplification instrument of this design.
[0057] Specifically, in this embodiment, a replacement contact piece 121 is provided at the position corresponding to the first control member 420 on the slot cover 120. The replacement contact piece 121 is detachably connected to the slot cover 120. Specifically, the replacement contact piece 121 is detachably connected to the slot cover 120 through a threaded structure.
[0058] During prolonged use, the replacement contact piece 121 may wear out. In this case, the old replacement contact piece 121 can be removed and replaced with a new one, thus ensuring that the vertical lifting structure 300 of the gene amplification instrument can continue to be used normally. This avoids the first control component 420 not being able to be fully pressed down after the replacement contact piece 121 wears out, thereby preventing the second control component 430 from not being horizontal when the slot cover 120 is fully closed, which would result in a slight height difference between the multiple vertical lifting structures 300. This also avoids uneven heating of multiple rows of test tubes, which is beneficial to ensuring the effectiveness of the gene amplification instrument of this design.
[0059] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
