Description

Technical Field

[0001] The utility model belongs to the technical field of medical testing equipment, and in particular relates to a tube cover pressing device for eight-link tubes. Background Art

[0002] After the reagents are added to the eight-tube strip, the tube cap needs to be pressed into the tube and tightly closed, and then amplified and tested on the machine. Since the tube and tube cap of the eight-tube strip are separate, the tube cap needs to be pressed tightly onto the tube by hand, so there is a problem that some tube caps are not tightly closed; and the temperature during subsequent amplification is high (up to 95°C), and the tube cap that is not tightly closed is easily opened after being heated, causing the solution in the tube to splash, burn hands and contaminate.

[0003] After the amplification is completed, reagents need to be added to the tube for hybridization. At this time, the tube cap needs to be opened and closed manually. Manual operation is inefficient, and when the sample volume is large, continuously opening and pressing the tube cap can easily cause hand injuries. Utility Model Content

[0004] The utility model provides an eight-tube cover pressing device to solve the technical problems that the eight-tube cover tightening speed is slow and the tube cover is easy to be opened after heating on the machine, resulting in pollution.

[0025] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate the present invention in conjunction with the accompanying drawings. These examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.

[0026] Example 1

[0027] An eight-tube cover pressing device, such as Figure 1-Figure 5 As shown, it includes: a clamping mechanism 1, including a base 11, a bracket 12, a clamping device 13, and a clamping plate 14; the bracket 12 is arranged on the base 11, the clamping device 13 is arranged on the bracket 12, and the clamping plate 14 is downwardly arranged on the clamping device 13; a bearing seat 2, a plurality of pipe holes 21 are distributed on the top; when in use, the bearing seat 2 is placed below the clamping plate 14.

[0028] like Figure 1-Figure 3 As shown, each tube hole 21 is located in the vertical projection area of ​​the pressing plate 14. Figure 1 As shown, the clamping mechanism 1 further includes: a groove 15 , which is arranged at a position of the clamping plate 14 relative to the base 11 ; the bearing seat 2 can be placed in the groove 15 .

[0029] The clamping device can be a cylinder, an electric push rod, etc. The clamping plate is connected to the piston rod of the cylinder and the push rod end of the electric push rod.

[0030] The provided groove is used to limit the position of the placed bearing seat to avoid movement due to accidental contact, and ensure that the bearing seat is under the clamping plate, so that during the clamping operation, the clamping plate can press the tube cover into the eight-unit tube.

[0031] The tube holes on the bearing seat are arranged at equal intervals, and multiple rows can be arranged in parallel, so that the tube cover pressing operation can be performed on multiple groups of eight-tube joints at the same time, thereby improving efficiency.

[0032] The tube holes are located within the vertical projection area of ​​the clamping plate, so that the tube covers within the tube hole area can be pressed into the eight-unit tube during clamping.

[0033] When in use, the eight-tube strip is placed in the tube hole of the supporting seat, and then the tube cover is placed at the tube mouth of the eight-tube strip; the clamping device is started, and the operation of the clamping device drives the clamping plate to move downward. When the clamping plate contacts the tube cover, it will continue to press downward to press the tube cover into the eight-tube strip and seal it tightly; after completing the clamping operation, the clamping device is controlled to run in reverse to drive the clamping plate to move upward, and then the sealed eight-tube strip can be taken out.

[0034] Example 2

[0035] On the basis of Example 1, the present invention also has the following technical features:

[0036] like Figure 4 As shown, the bearing seat 2 further includes: a connecting groove 22, which is arranged along the length and / or width direction of the bearing seat 2; the connecting groove 22 connects adjacent tube holes 21, and the top of the part between the adjacent tube holes 21 is open.

[0037] like Figure 4-Figure 6 As shown, the clamping device also includes: a movable frame 3, which is movably clamped at one end of the bearing seat 2; a slide groove 31, which is arranged at both ends of the movable frame 3 and is parallel to the connecting groove 22; and the movable frame 3 can slide along the slide groove 31.

[0038] like Figure 4-Figure 6 As shown, when the movable frame 3 is on the slide groove 31, the bottom can be attached to the top of the tightly closed pipe cover.

[0039] Since the eight-tube connection is formed by connecting eight tubes, there is a connection between two connected tubes; in order to place the eight-tube connection neatly and avoid the connection of the tubes being on the bearing seat, a connection groove is set; when in use, the eight-tube connection can be placed in the tube hole and slightly pressed down so that the connection of the tubes is immersed in the connection groove; the width of the connection groove can be slightly greater than or equal to the width of the connection of the tubes. A storage groove can be set at the end of the initial position of the movable frame relative to the bearing seat, so that the movable frame is in the storage groove when not in use, and the top of the movable frame is flush with the top of the bearing seat; when it needs to be used, the movable frame is lifted up and slid along the slide groove; the two sides of the sliding frame can be stuck in the storage groove and the slide groove.

[0040] During the experiment, after adding samples and reagents to the eight-tube strip, the tube caps are tightly closed and amplification is performed; after the end, the tube caps must be opened and reagents must be added for hybridization; however, since the eight-tube strip is made up of eight tubes connected together and the tubes are small in size, when opening the tube caps, one hand is used to hold the tubes and the other hand is used to open the tube caps, which is laborious and inconvenient to operate; therefore, a movable stand is provided; when in use, the movable stand is moved to a suitable position to press on the next unopened tube cap (for example, when opening the tube cap of the first tube, the movable stand can be stuck on the tube cap of the second tube), so that when each tube cap is opened, the movable stand is slid backward in turn to press on the next tube cap, and when the last tube cap is reached, the movable stand slides back to the initial position.

[0041] When the cover opening operation is required, the eight-tube strip is placed into the tube hole of the supporting seat, and the movable frame is slid so that its bottom is against the top of the next tube cover that has not been opened to prevent it from moving, and then the previous tube cover can be opened by hand, thus improving the convenience of the cover opening operation.

[0042] Example 3

[0043] On the basis of Example 2, the present invention also has the following technical features:

[0044] like Figure 5 As shown, the bearing seat 2 also includes: a top plate 23 movably mounted on the bearing seat 2 ; a bearing groove 24 disposed in the bearing seat 2 , with the top plate 23 disposed on the top; and a pipe hole 21 penetrating the top plate 23 and communicating with the bearing groove 24 .

[0045] like Figure 5 As shown, the top plate 23 may be provided with several pieces, and the pipe holes 21 and connecting grooves 22 provided thereon are adapted to eight-piece tubes of different specifications.

[0046] Since different eight-tube strips have different sizes, the bearing groove arranged on the bearing seat is at a certain distance from the top plate, which can avoid that there is insufficient accommodation space at the bottom when the eight-tube strips are placed, and ensure that the connection between the two tubes is in the connection groove.

[0047] The height of the movable frame is smaller than the height of the top plate, so that a storage slot can be arranged on the top plate, and the movable frame can be placed in the storage slot when not in use.

[0048] Since the eight-tube strips used in the experiment may have different sizes, in order to improve the applicability of the clamping device, the top plate is set as a movable structure; multiple top plates can be preset according to the diameter of the eight-tube strips used, and can be selected according to needs during use.
