Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nucleic acid extraction, in particular to a nucleic acid purification column pressing ring component. Background Art
[0002] The pressing ring is a circular plastic component used to fix the nucleic acid adsorption membrane to the column. There are roughly two existing types of pressing rings: one is the pressing ring without a central support leg, which is purely a circular plastic component. This type of pressing ring can be either pressed by a machine or manually placed into the column and then pressed into the fixed position. The manual operation efficiency of this type of pressing ring is relatively low. Generally, machine operation is preferred. For the pressing ring without a central support leg, if operated manually, the efficiency is relatively low, directly affecting the output and resulting in a relatively high labor cost per unit product;
[0003] The second type is the pressing ring with three auxiliary support legs in the middle (such as Figure 4 ), which is used for the auxiliary tool to grab and then place into the column. Since this type of pressing ring is more suitable for manual processing operations, this solution aims to improve this type of pressing ring to better apply it in production, reduce production costs, and improve production efficiency; for the pressing ring with support legs in the middle, the pressing ring can be placed at a specific position in the column with the assistance of tools. However, this type of pressing ring also has a relatively large problem, that is, it has relatively high precision requirements for product manufacturing. The distance between the three support legs in the middle of the pressing ring needs to match the corresponding tool relatively closely. If it is too loose, the tool cannot hook up the pressing ring. On the contrary, if it is too tight, it is relatively difficult to hook up the pressing ring with the tool. After placing the pressing ring at a specific position in the column, it is not easy to take out the tool. Content of the Utility Model
[0004] The purpose of the utility model is to provide a nucleic acid purification column pressing ring component to solve the problems of relatively high production precision requirements, high costs, and low production efficiency of the existing gaskets mentioned in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a nucleic acid purification column pressing ring component, including a column sleeve, the column sleeve includes a placement groove, a pressing ring is placed inside the placement groove, and a support leg is integrally formed and inclined inside the pressing ring.
[0006] Preferably, three support legs are provided.
[0007] Preferably, the support legs are evenly distributed on the inner wall of the pressing ring.
[0008] Preferably, a fixing groove is opened on the outer side of the pressing ring, and an elastic plate is integrally formed at the bottom of the inner cavity of the fixing groove.
[0009] Preferably, there are two fixing grooves and two elastic plates, and the two fixing grooves are symmetrically arranged.
[0010] Compared with the prior art, the beneficial effect of the present utility model is as follows: For this nucleic acid purification column pressing ring component, through a specific design, the three feet in the pressing ring are rotated by a certain angle. In this way, the force application directions at the tops of the three feet will change from being perpendicular to the edge of the pressing ring to having a certain deflection angle. When an external force is applied and deformation occurs, due to the deflection of the feet, the force application direction changes. Even when the fit between the feet of the pressing ring and the tool is relatively tight, at this time, it is easier to hook up the pressing ring with a tool and place it at the designated position in the column sleeve. Through this specific design, the requirement for the manufacturing precision of the feet can be reduced. Even when the fit between the feet and the tool is relatively tight, it is still easier to place the subsequent washer in the column sleeve. When placed in the placement groove of the column sleeve, it will squeeze the elastic plate, causing the elastic plate to be received in the fixing groove, and the resilience of the elastic plate will cause one end of the elastic plate to abut against the inner wall of the placement groove for better positioning.

[0018] Embodiment 1
[0019] Please refer to Figure 1-2 , a pressing ring component of a nucleic acid purification column of the present utility model: It includes a column sleeve 1. The column sleeve 1 includes a placement groove 2. A pressing ring 3 is placed inside the placement groove 2. An inclined support leg 4 is integrally formed on the inner side of the pressing ring 3. Through a specific design, the three support legs 4 in the pressing ring 3 are rotated by a certain angle. In this way, the force application directions at the tops of the three support legs 4 will change from being perpendicular to the edge of the pressing ring to having a certain deflection angle. In this way, when an external force is applied and deformation occurs, due to the deflection of the support legs 4, the force application direction changes. Even when the fit between the support legs 4 of the pressing ring and the tool is relatively tight, due to the change in the force application direction, at this time, it is also relatively easy to hook up the pressing ring with a tool and place it at the designated position in the column sleeve 1. Through this specific design, the manufacturing precision requirements for the support legs 4 can be reduced. Even when the fit between the support legs 4 and the tool is relatively tight, it is also relatively easy to place the subsequent washer 3 in the column sleeve 1.
[0020] Furthermore, there are three support legs 4.
[0021] Furthermore, the support legs 4 are evenly distributed on the inner wall of the pressing ring 3.
[0022] Embodiment 2
[0023] Different from the above embodiment, please refer to Figure 2-3, a fixing groove 5 is provided on the outer side of the retaining ring 3, and a spring plate 6 is integrally formed at the bottom of the inner cavity of the fixing groove 5. Through a specific design, the three legs 4 in the retaining ring 3 are rotated by a certain angle, so that the force application directions at the tops of the three legs 4 will change from being perpendicular to the edge of the retaining ring to having a certain deflection angle. In this way, when an external force is applied and deformation occurs, due to the deflection of the legs 4, the force application direction changes. Even when the clearance between the legs 4 of the retaining ring and the tool is relatively small, due to the change in the force application direction, at this time, it is also relatively easy to hook up the retaining ring with a tool and place it at the designated position in the bushing 1. Through this specific design, the manufacturing precision requirements for the legs 4 can be reduced. Even when the clearance between the legs 4 and the tool is relatively small, it is also relatively easy to place the subsequent washer 3 in the bushing 1. When placed in the placement groove 2 of the bushing 1, the spring plate 6 will be squeezed, causing the spring plate 6 to be received in the fixing groove 5, and the resilience of the spring plate 6 will cause one end of the spring plate 6 to abut against the inner wall of the placement groove 2 for better positioning.
[0024] Furthermore, there are two fixing grooves 5 and two spring plates 6, and the two fixing grooves 5 are symmetrically arranged.
[0025] Working principle: Through a specific design, the three legs 4 in the retaining ring 3 are rotated by a certain angle, so that the force application directions at the tops of the three legs 4 will change from being perpendicular to the edge of the retaining ring to having a certain deflection angle. In this way, when an external force is applied and deformation occurs, due to the deflection of the legs 4, the force application direction changes. Even when the clearance between the legs 4 of the retaining ring and the tool is relatively small, due to the change in the force application direction, at this time, it is also relatively easy to hook up the retaining ring with a tool and place it at the designated position in the bushing 1. Through this specific design, the manufacturing precision requirements for the legs 4 can be reduced. Even when the clearance between the legs 4 and the tool is relatively small, it is also relatively easy to place the subsequent washer 3 in the bushing 1. When placed in the placement groove 2 of the bushing 1, the spring plate 6 will be squeezed, causing the spring plate 6 to be received in the fixing groove 5, and the resilience of the spring plate 6 will cause one end of the spring plate 6 to abut against the inner wall of the placement groove 2 for better positioning.
[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
