Description

Technical Field

[0001] The utility model relates to the technical field of nucleic acid extraction equipment, in particular to a clamp device for a nucleic acid extraction instrument. Background Art

[0002] Nucleic acid testing technology plays a crucial role in modern medicine, biology, and public health. It can accurately detect the presence of various pathogens, providing a key basis for early disease diagnosis, epidemic prevention and control, and the development of treatment plans. It also has widespread applications in genetic disease screening and biological science research.

[0003] Nucleic acid extraction is a core step in nucleic acid testing. High-quality nucleic acid extraction is crucial for ensuring the accuracy and reliability of subsequent test results. Nucleic acid extractors, specialized equipment for nucleic acid extraction, provide powerful technical support for large-scale nucleic acid testing. During nucleic acid extraction, the sample to be tested is typically placed in a sample tube, which is then stored in the wells of a deep-well plate.

[0004] As one of the commonly used containers in the nucleic acid extraction process, the deep-well plate has no unified standard for its external dimensions. The sizes of deep-well plates produced by different manufacturers vary, resulting in the inability of the clamp device of the existing nucleic acid extraction instrument to stably fix deep-well plates of different specifications, affecting the stability and accuracy of nucleic acid extraction. Utility Model Content

[0005] In view of the problem that the well plate is one of the commonly used containers in the nucleic acid extraction process in the prior art, there is no unified standard for its external dimensions, and the sizes of deep-well plates produced by different manufacturers vary, resulting in the inability of the clamp device of the existing nucleic acid extraction instrument to stably fix deep-well plates of different specifications, affecting the stability and accuracy of nucleic acid extraction, the utility model proposes a clamp device for a nucleic acid extraction instrument.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] A clamp device for a nucleic acid extractor, comprising a base; a rectangular plate is provided on the base, a rectangular hole is provided at the center of the rectangular plate, and clamps are provided on the left and right sides of the rectangular hole along the axis thereof, which can move left and right in the rectangular hole, and the clamps include a horizontal plate and a vertical plate arranged on the upper end surface of the horizontal plate; vertical plates are also fixed to the two ends of the clamping plate, and the vertical plate is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to a clamping block arranged on the upper end surface of the horizontal plate.

[0008] When the clamp device is in use, the deep-hole plate is overlapped on the horizontal plate, and the position between the two clamping plates is adjusted so that the side wall of the deep-hole plate is pressed against the vertical plate to achieve left and right clamping of the deep-hole plate; the setting of the vertical plate, the first spring and the clamping block realizes the front and rear clamping and limiting of the deep-hole plate, so that the clamp device can stably clamp a variety of limit plates of different specifications.

[0009] Preferably, the upper end surface of the rectangular plate is provided with mounting grooves located on both sides of the rectangular hole, and a first connecting plate is fixed to the side of the vertical plate far from the rectangular hole. The lower end surface of the first connecting plate extends downward to form a second connecting plate, and the second connecting plate extends into the mounting groove. When the splint moves left and right in the rectangular hole, the second connecting plate moves back and forth in the mounting groove.

[0010] Through the mutual cooperation between the first connecting plate, the second connecting plate and the installation groove, the installation of the clamping plate in the rectangular hole is preferably achieved.

[0011] Preferably, a second spring is fixedly connected to one side of the second connecting plate far from the rectangular hole, and the other end of the second spring is fixedly connected to a limiting plate, and the limiting plate rests on the side wall of the mounting groove under the action of the second spring.

[0012] When the position of the splint needs to be adjusted, the limit plate is pressed to disengage the limit plate from the side wall of the installation slot; when the position adjustment is completed, the limit plate rests on the side wall of the installation slot under the action of the second spring, thereby fixing the position of the opposing plate and the splint, and avoiding position displacement of the deep hole plate on the splint during the use of the clamp device.

[0013] Preferably, a limiting column is provided on one side of the limiting plate near the rectangular hole, and a through hole is provided on the second connecting plate for the limiting column to extend into, and the limiting column moves in the through hole when the second spring is pressed.

[0014] By providing the limiting posts and the through holes, the limiting between the limiting plate and the second connecting plate is preferably achieved, thereby preventing personnel from mistakenly taking the limiting plate out of the installation slot.

[0015] Preferably, a circular plate is provided at one end of the limiting column extending into the through hole, and the opening of the through hole extends inwardly to form an annular plate for limiting the circular plate.

[0016] The arrangement of the circular plate and the annular plate enables the limiting post to be positioned within the through hole, thereby preventing the limiting post from leaving the through hole.

[0017] Preferably, the second spring is sleeved on the limiting column.

[0018] The arrangement of the second spring being sleeved on the limiting column makes the clamp device more compact.

[0019] As a preference, the upper end surface of the limiting plate extends out of the mounting groove.

[0020] The mounting slot extending from the upper end face of the limit plate allows the worker to press the limit plate more easily and move the position of the splint. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0028] Example

[0029] like Figure 1-4 As shown, a clamp device for a nucleic acid extractor includes a base 110; a rectangular plate 120 is provided on the base 110, a rectangular hole 1201 is provided at the center of the rectangular plate 120, and clamps that can move left and right in the rectangular hole 1201 are provided on the left and right sides along the axis of the rectangular hole 1201, and the clamps include a horizontal plate 130 and a vertical plate 140 arranged on the upper end surface of the horizontal plate 130; vertical plates 1501 are also fixed to both ends of the clamping plate, and the vertical plate 1501 is fixedly connected to a first spring 1502, and the other end of the first spring 1502 is fixedly connected to a clamping block 1503 arranged on the upper end surface of the horizontal plate 130.

[0030] When the clamp device is in use, the deep-hole plate is overlapped on the horizontal plate 130, and the position between the two clamping plates is adjusted so that the side wall of the deep-hole plate is against the vertical plate 140, thereby achieving left and right clamping of the deep-hole plate; the setting of the vertical plate 1501, the first spring 1502 and the clamping block 1503 realizes the front and rear clamping and limiting of the deep-hole plate, so that the clamp device can stably clamp a variety of limiting plates 170 of different specifications.

[0031] The upper end surface of the rectangular plate 120 is provided with mounting grooves 1202 located on both sides of the rectangular hole 1201. A first connecting plate 160 is fixed to the side of the vertical plate 1501 far from the rectangular hole 1201. The lower end surface of the first connecting plate 160 extends downward to form a second connecting plate 1601. The second connecting plate 1601 extends into the mounting groove 1202. When the splint moves left and right in the rectangular hole 1201, the second connecting plate 1601 moves back and forth in the mounting groove 1202.

[0032] Through the mutual cooperation between the first connecting plate 160 , the second connecting plate 1601 and the installation groove 1202 , the installation of the clamping plate in the rectangular hole 1201 is preferably achieved.

[0033] A second spring 1602 is fixedly attached to the side of the second connecting plate 1601 distal from the rectangular hole 1201. The other end of the second spring 1602 is fixedly attached to a limiting plate 170. The limiting plate 170 is pressed against the sidewall of the mounting slot 1202 by the action of the second spring 1602. A limiting post 1701 is provided on the side of the limiting plate 170 proximal to the rectangular hole 1201. The second connecting plate 1601 is provided with a through-hole 1603 for the limiting post 1701 to extend into. Pressing the second spring 1602 causes the limiting post 1701 to move within the through-hole 1603. A circular plate 1702 is provided at the end of the limiting post 1701 that extends into the through-hole 1603. The opening of the through-hole 1603 extends inward to form an annular plate 1604 that limits the circular plate 1702. The second spring 1602 is sleeved onto the limiting post 1701. The upper end surface of the limiting plate 170 extends out of the mounting slot 1202.

[0034] When the position of the splint needs to be adjusted, press the limit plate 170 to disengage the limit plate 170 from the side wall of the mounting groove 1202; when the position adjustment is completed, the limit plate 170 rests on the side wall of the mounting groove 1202 under the action of the second spring 1602, thereby fixing the position of the opposing plate 1501 and the splint, and avoiding position displacement of the deep hole plate on the splint during the use of the clamp device.

[0035] By providing the limiting posts 1701 and the through holes 1603 , the limiting between the limiting plate 170 and the second connecting plate 1601 is preferably achieved, thereby preventing personnel from mistakenly taking the limiting plate 170 out of the mounting groove 1202 .

[0036] The arrangement of circular plate 1702 and annular plate 1604 limits the position of limiting post 1701 within through-hole 1603, preventing it from leaving through-hole 1603. The arrangement of second spring 1602 sleeved on limiting post 1701 makes the clamping device more compact. The upper end surface of limiting plate 170 extends out of mounting slot 1202, making it easier for a worker to press limiting plate 170 and thereby adjust the position of the clamp.

[0037] In short, the above is only a preferred embodiment of this embodiment, and all equivalent changes and modifications made according to the scope of the patent application of this embodiment should fall within the scope of coverage of the patent of this embodiment.
