Description

Technical Field

[0001] The utility model relates to the technical field of DNA automated detection, in particular to a hatch structure of a gene analyzer. Background Art

[0002] Capillary electrophoresis (CE) is a new technology that uses a high-voltage DC electric field as a driving force to efficiently and quickly separate ions or charged particles in a capillary according to their mobility and / or distribution coefficient.

[0003] For integrated equipment in the field of biological detection and analysis, such as the current cutting-edge gene analyzers or Sanger sequencers, the capillary electrophoresis separation system has natural advantages based on its miniaturization and automation. However, when using the current gene analyzer, the sample table needs to frequently enter and exit the shell of the gene analyzer to perform operations such as replacing samples and cathode reaction liquid. Therefore, a resettable hatch will be set on the gene analyzer. When the sample table is out of the chamber, the hatch will automatically open. When the sample table returns to the chamber, the hatch can be automatically closed by the torsion spring without manual opening. However, the existing hatch structure is limited by the effective stroke of the torsion spring, the hatch opening and closing angle is small, and interference is easy to occur when the sample table is out of the chamber or in the chamber. In addition, the torsion spring will be fatigued and damaged after repeated use, resulting in the hatch not closing tightly or even unable to close, and the maintenance frequency is high. Utility Model Content

[0004] The utility model provides a hatch structure of a gene analyzer, which has the effect of large opening angle and is not easily damaged after repeated opening and closing. The specific technical scheme is as follows:

[0005] A door structure of a gene analyzer includes a front shell and a door panel. The front shell is provided with an opening for accommodating the door panel. The door panel is hinged to the front shell and can rotate relative to the front shell to realize opening and closing of the door panel. The door panel is connected to the front shell by a tension spring. A limit frame is provided in the opening. The tension of the tension spring can make the door panel collide with the limit frame to keep the door panel closed.

[0006] Furthermore, the door panel is L-shaped, the vertical end of the L-shape is a shielding portion, which contacts the limit frame under the tension of the tension spring, and the horizontal end of the L-shape is a hinged portion, which is hinged to the bottom of the front shell.

[0007] Furthermore, a hinge column is provided at the end of the hinge part, a hinge hole is provided on the hinge column, and a hinge hole is also provided at the bottom rear position of the front shell body. The intersection hole of the front shell body and the hinge column is connected through a hinge shaft to realize the hinge connection between the door panel and the front shell body.

[0008] Furthermore, a limiting beam is arranged near the lower part of the limiting frame, and the limiting beam can further limit the door panel; a first tension spring connecting part is arranged behind the limiting beam, and a second tension spring connecting part is arranged on the top surface of the hinge part, the first tension spring connecting part is connected to one end of the tension spring, and the other end of the tension spring is connected to the second tension spring connecting part.

[0012] Furthermore, there are multiple grooves evenly distributed on both sides of the rear surface of the door panel, and reinforcing ribs are formed between two adjacent grooves to ensure the strength of the door panel.

[0013] Furthermore, it also includes a carrying unit, which is arranged at the bottom of the sample table in the cabin, and the carrying unit can carry the sample table to move to complete the movement of entering and exiting the warehouse; the carrying unit includes a top door column, which is arranged below the sample table. When the sample table of the genetic analyzer is out of the warehouse, the top door column can interfere with the door panel and push the door panel open, thereby completing the movement of the sample table out of the warehouse.

[0014] Furthermore, a striking portion is provided at the front end of the top door post, which is semicircular, and an arc-shaped sliding portion is provided on the lower surface of the top door post, and the striking portion is tangent to the sliding portion to avoid jamming of the top door post when it slides on the door panel.

[0025] In order to better understand the purpose, function and specific design of the utility model, the hatch structure and arrangement method of the gene analyzer of the utility model are further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-7As shown, the door structure of the gene analyzer of the utility model includes a front shell 1 and a door panel 2. The front shell 1 is provided with an opening for accommodating the door panel 2. The door panel 2 is hinged to the front shell 1. The door panel 2 can rotate relative to the front shell 1 to realize the opening and closing of the door panel 2. The door panel 2 is connected to the front shell 1 through a tension spring 3. A limit frame 11 is provided in the opening. The tension of the tension spring 3 can make the door panel 2 conflict with the limit frame 11 to keep the door panel 2 closed.

[0027] Specifically, if Figure 4-7 As shown, the door panel 2 is L-shaped, the vertical end of the L-shape is the shielding portion 21, and the shielding portion 21 is in conflict with the limit frame 11 under the tension of the tension spring 3, and the horizontal end of the L-shape is the hinge portion 22, and the hinge portion 22 is hinged to the bottom of the front housing 1. The hinge portion 22 of this embodiment is provided with a hinge column 23 at the end thereof, and a hinge hole is provided on the hinge column 23. Correspondingly, a hinge hole is also provided at the rear position of the bottom of the front housing 1. The intersection hole between the front housing 1 and the hinge column 23 is connected through a hinge shaft 4 to realize the hinge connection between the door panel 2 and the front housing 1. Preferably, the hinge column 23 is symmetrically arranged at both ends of the hinge portion 22, which improves the hinge stability of the door panel 2 and facilitates the installation of the door panel 2.

[0028] like Figure 5 and Figure 6 As shown, a limiting cross beam 12 is provided near the lower part of the limiting frame 11, and the limiting cross beam 12 can further limit the door panel 2 to improve the reliability of the limit. A first tension spring connection part 13 is provided behind the limiting cross beam 12, and a second tension spring connection part 24 is provided on the top surface of the hinge part 22. The first tension spring connection part 13 is connected to one end of the tension spring 3, and the other end of the tension spring 3 is connected to the second tension spring connection part 24. The tension of the tension spring 3 can make the door panel 2 collide with the limiting frame 11 to keep the door panel 2 closed.

[0029] The first tension spring connecting part 13 is provided with a first connecting hole, and a first tension spring shaft 31 is provided in the first connecting hole. The second tension spring connecting part 24 is provided with a second connecting hole, and a second tension spring shaft 32 is provided in the second connecting hole. Both ends of the tension spring 3 are respectively connected to the first tension spring shaft 31 and the second tension spring shaft 32 to realize the connection between the tension spring 3 and the front shell body 1 and the door panel 2.

[0030] Preferably, there are two groups of first tension spring connection parts 13 and second tension spring connection parts 24, which are symmetrically arranged on both sides of the limiting cross beam 12 and the hinge part 22, and there are two tension springs 3, which are respectively connected to each group of first tension spring connection parts 13 and second tension spring connection parts 24. The use of two groups of tension springs 3 can improve the restoring force of the door panel 2 and ensure the reliability of the door panel 2 when working. In addition, when one group of tension springs 3 is damaged, the other group of tension springs 3 can also ensure the normal use of the door panel 2, so as to ensure the reliability of the gene analyzer when in use.

[0031] It is worth noting that Figure 5 and Figure 7 As shown, a groove 25 is provided on the rear surface of the door panel 2 of this embodiment to reduce the weight of the door panel 2. A plurality of grooves 25 are evenly distributed on both sides of the rear surface of the door panel 2, and a reinforcing rib 26 is formed between two adjacent grooves 25 to ensure the strength of the door panel 2.

[0032] like Figure 2-3 As shown, the door structure of the gene analyzer of the utility model also includes a bearing unit 5, which is arranged at the bottom of the sample table 4 in the cabin. The bearing unit 5 can carry the sample table 4 to move, so as to complete the action of exiting and entering the cabin. The bearing unit 5 includes a top door column 51, which is arranged below the sample table 4. When the sample table 4 of the gene analyzer exits the cabin, the top door column 51 can collide with the door panel 2 and push the door panel 2 open, thereby completing the exit action of the sample table 4. Since the sample table 4 is equipped with test tubes and samples to be tested, the sample table 4 has a certain height, so the door panel 2 needs to have a larger opening angle. Therefore, the lower surface of the top door column 51 of this embodiment is provided with an arc-shaped sliding portion 52. As the top door column 51 extends, the sliding portion 52 gradually conflicts with the door panel 2. Driven by the sliding portion 52, the door panel 2 expands at an increasing angle until the sample table 4 is fully extended. When the sample table 4 enters the warehouse, the door panel 2 is guided by the sliding portion 52, and the expansion angle gradually decreases. When the sample table 4 is fully entered, the door panel 2 is closed under the action of the tension spring. The cooperation between the door panel 2 and the sliding portion 52 of the top door column 51 makes the expansion and closing of the door panel 2 smoother, and also prevents the door panel 2 from interfering with the sample table 4 and causing jamming.

[0033] Preferably, a collision block is also provided at the front end of the sample platform 4. The collision block is made of elastic material, and in this embodiment, it is made of rubber. The collision block can act as a buffer when the sample platform 4 hits the door panel 2 to protect the sample platform 4 from damage due to accidental impact with the door panel 2.

[0034] It is worth noting that the front end of the top door post 51 is provided with a striking portion 53, which is semicircular and tangent to the sliding portion 52. The semicircular striking portion 53 allows the top door post 51 to be in line contact when striking the door panel 2, thereby avoiding jamming when the top door post slides on the door panel 2, so that the door panel 2 can be unfolded more smoothly. The tangent of the striking portion 53 and the sliding portion 52 can make the door panel 2 move more smoothly when switching between the striking portion 53 and the sliding portion 52, avoiding jamming that affects the unfolding or closing of the door panel 2.

[0035] The hatch door structure of the gene analyzer of the utility model is cleverly designed and simple in structure. The cooperation of the L-shaped door panel and the tension spring greatly improves the opening angle of the door panel and has a long service life. The tension spring is not easy to be damaged by fatigue, which improves the reliability of the door panel during use and reduces the accident rate. In addition, the cooperation between the door panel and the sliding part of the top door column makes the opening and closing actions of the door panel smoother, and also prevents the door panel from interfering with the sample table to cause jamming, so that users have a good experience.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
