Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, and more specifically to a suction head extractor. Background Art

[0002] Tips refer to disposable plastic pipette tips used in scientific research or testing experiments. They are tools used with pipettes. Their main function is to accurately aspirate and transfer small amounts of liquid. These tips are designed to be easily connected to the bottom of the pipette and are discarded after use to prevent cross contamination. Tips come in a variety of specifications and are suitable for liquid transfers in different volume ranges. They are widely used in laboratory work in the fields of biology, chemistry, and medical research.

[0003] Pipette tips have a wide range of applications, good cost-effectiveness, and good physical properties such as low adsorption, making them very popular and in great demand. Currently, there are two main types of common pipette tip products available on the market, namely bulk (bagged) pipette tips and boxed pipette tips.

[0004] Bulk tips are usually packed in bags, and you need to install them in your own tip box for use. Boxed tips include a tip box in each package, and the tips are already installed in the tip box according to the hole positions and can be directly taken out. Because boxed tips are easy to use and operate, and reduce contact with people during use, avoiding contamination during the test process and expanding the scale of use, customers' requirements for tip packaging have gradually shifted to boxed methods, and the demand for boxed tips is increasing.

[0005] After the boxed pipette tips are used, the pipette tip box will be scrapped along with the used pipette tips. Since most customers use disposable pipette tips, a large number of packaging boxes and pipette tips will be scrapped during use, resulting in a waste of resources.

[0006] In summary, although the existing boxed pipette tips can avoid pollution and are easy to use, the pipette tip box can only be scrapped together with the pipette tips after use, which causes serious waste of resources and increases the cost of the experiment. Utility Model Content

[0053] refer to Figure 1 The utility model provides a suction tip extractor 100, comprising:

[0054] Plug-in device 1 and release device 2;

[0055] The plug-in device 1 is used to plug in the suction head 400;

[0056] The release device 2 is movably connected to the plug-in device 1 and can move relative to the plug-in device 1 to separate and release the suction head 400 plugged on the plug-in device 1 from the plug-in device 1 .

[0057] Above, reference Figure 2 The plug-in device 1 and the release device 2 are two detachably connected parts, and after the two parts are combined, they constitute a suction tip extractor 100 as a whole.

[0058] The plug-in device 1 can be plugged with each of the pipette tips in the box, so that the plug-in device 1 is connected to the pipette tip 400 .

[0059] The release device 2 can move relative to the plug-in device 1, and the two parts can be movably linked. When the release device 2 moves relative to the plug-in device 1, it can contact the suction head 400 connected to the plug-in device 1, and can separate the plugged suction head 400 from the plug-in device 1 by abutting, thereby releasing the suction head 400 to the target suction head box 300 to be transferred, and completing the extraction and transfer of the suction head 400.

[0060] The tip extractor 100 provided by the utility model, after the plug-in device 1 is combined with the release device 2 and the plug-in box loaded with tips is plugged into the plug-in device 1, it is transferred to the target tip box 300 where the tips 400 need to be placed, and the release device 2 is controlled to move away from the plug-in device 1 and separate and release the plugged tips 400 from the plug-in device 1, so that the tips 400 are placed into the target tip box 300, thereby completing the extraction and transfer of the tips 400.

[0061] The tip extractor 100 provided by the utility model can quickly extract multiple tips 400 or a whole box of tips 400, whether it is unused tips 400 or used tips 400, during the use of boxed tip products, which is convenient, fast and easy to operate; the tips 400 can be quickly turned over from the tip box 400, the tip box 400 can be recycled, the utilization rate of the tip box 400 is improved, and the cost of scrapping the tip box 400 along with the tips 400 is reduced.

[0062] For further reference, Figure 3 The plug-in device 1 includes a substrate 11 and a plug-in array 12 arranged on the substrate 11 and composed of a plurality of plug-in units 121.

[0063] As mentioned above, the plug-in device 1 is a plate-shaped structure, including a base plate 11 and a plug-in array 12 .

[0064] A plurality of plug-in units 121 are disposed on the substrate 11 , and the plug-in array 12 on the substrate 11 is formed by arranging the plurality of plug-in units 121 at a certain interval, a certain specification, and a certain position.

[0065] The plug-in unit 121 is used to connect with the plug-in slot 401 of the suction tip 400, so the size of the plug-in unit 121 is adapted to the size of the suction tip 400 that needs to be plugged in. Similarly, the arrangement spacing of the plug-in unit 121 is adapted to the specifications of the boxed suction tips that need to be plugged in. Therefore, the suction tip extractor 100 provided in the utility model can select different specifications according to the different plug-in devices 1 as needed, so as to adapt to suction tip boxes 400 and suction tips 400 of different specifications.

[0066] For further reference, Figure 4 , the plug-in unit 121 includes a column 1211 and a plug connector 1212 connected to the column 1211;

[0067] The column 1211 is disposed on the substrate 11;

[0068] The plug connector 1212 is disposed at an end of the column 1211 away from the substrate 11 .

[0069] The column 1211 is provided with a plug connector 1212 for plugging into the plug slot 401 of the suction head 400 .

[0070] Furthermore, the plug connector 1212 is a structure whose outer diameter is limited by the column 1211 in a direction away from the substrate 11 .

[0071] The outer diameter of the plug connector 1212 may be different from the outer diameter of the column 1211. The plug connector 1212 extends outward from the column 1211 and gradually shrinks. The shrinking shape may form a round head or a pointed head. The plug connector 1212 is adapted to the size of the suction head 400 so that it can be inserted into the plug slot 401 of the suction head 400 through interference fit.

[0072] Furthermore, the plug connector 1212 includes a connector body 12121 and an elastic member 12122 disposed on the connector body 12121 for increasing friction.

[0073] After the plug connector 1212 is connected to the suction head 400, the suction head 400 may fall off or drop. In order to avoid this situation and to avoid manual operation to cause pollution, in the utility model, an elastic member 12122 is provided on the connector body 12121. The elastic member 12122 may be made of rubber, silicone, etc., has a certain elasticity, and can increase the friction with the inner side of the suction head 400, thereby making the connection between the suction head 400 and the plug connector 1212 more stable.

[0074] The elastic members 12122 can be arranged in pairs, and are arranged on both sides of the connector body 12121. When the suction head 400 is plugged in, the connector body 12121 enters the plugging slot 401 of the suction head 400, and the elastic members 12122 on both sides respectively contact the inner side walls of the plugging slot 401, thereby further increasing the contact area, improving the friction force, and improving the stability of the connection.

[0075] For further reference, Figure 5 and Figure 6 , the release device 2 includes a movable plate 21;

[0076] The movable plate 21 is provided with a hole array 22 consisting of a plurality of unit holes 221;

[0077] The unit hole position 221 corresponds to the position of the plug-in unit 121 on the substrate 11;

[0078] The movable plate 21 can be sleeved on the corresponding plug-in unit 121 through each unit hole 221 in the hole array 22 .

[0079] As mentioned above, the movable plate 21 is provided with unit holes 221 , and the plurality of unit holes 221 are arranged according to the specifications and distances of the suction tips 400 in the suction tip box 400 , forming a hole array 22 .

[0080] As mentioned above, the movable plate 21 is sleeved on the corresponding plug-in unit 121 through each unit hole 221 in the hole array 22, so that the release device 2 and the plug-in device 1 are combined into a whole.

[0081] When in use, the movable plate 21 can move relative to the plug-in unit 121 through the unit hole 221 , and move the base plate 11 close to the plug-in unit 121 upward, or move the suction head 400 plugged into the plug connector 1212 away from the base plate 11 close to the plug-in unit 121 .

[0082] When in use, the following processes (states) may be included:

[0083] (1) Plug status: reference Figure 7 , insert the pipette tip extractor 100 into the pipette tip 400 in the original pipette tip box 200;

[0084] (2) Status: Reference Figure 8 , lift the tip extractor 100, thereby lifting all the tips 400 in the original tip box 200;

[0085] (3) Release status: Reference Fig. 9, transferred to the upper end of the target tip box 300, after determining the corresponding position, the movable plate 21 is controlled to move downward, so that all the tips 400 plugged into the plug connector 1212 are pushed away and released into the target tip box 300.

[0086] Furthermore, a moving groove 12111 is provided in the length direction of the column 1211;

[0087] Each of the unit holes 221 of the movable plate 21 is provided with a protruding slider 222 corresponding to the moving groove 12111 and capable of being placed in the moving groove 12111;

[0088] The movable plate 21 moves along the length direction of the movable groove 12111 through the protruding slider 222 .

[0089] It should be noted that, corresponding to the size and area of ​​the boxed tips, the release device 2 and the plug-in device 1 are both horizontal plate-shaped structures, and both have a certain area in the horizontal direction. When the plug-in device 1 is connected to the tips 400 in the boxed tips and transferred, the release device 2 needs to be moved in the target tip box 300 to release the plugged tips 400 to the specified position. However, the release device 2 has a certain horizontal size. When moving, it is necessary to keep the positions of the movable plate 21 in all directions relative to the plug-in device 1 and move downward synchronously at the same time to ensure that the tips 400 connected to the plug connector 1212 fall synchronously. If the moving distances of each position are different, some tips 400 may fall off, while some tips 400 are still on the corresponding plug connector 1212. At this time, manual assistance or re-moval of the release device 2 is required. This defect may cause further contamination of the tips 400, causing inconvenience to the overall transfer of the tips 400.

[0090] To solve the above problems, in the utility model, a movable groove 12111 is provided in the length direction of each column 1211 as a slideway, and a protruding slider 222 is provided on the movable plate 21 for moving along the movable groove 12111 .

[0091] Specifically, the protruding slider 222 is disposed on each unit hole 221 , and can protrude from the unit hole 221 toward the inner circle thereof, so that the end of the protruding slider 222 can be placed in the movable groove 12111 .

[0092] Each raised slider 222 on the movable plate 21 slides along the corresponding movable groove 12111, thereby limiting the movement of the movable plate 21 along the column 1211, so that its direction and amplitude are limited by the movable groove 12111, so that the various parts of the release device 2 in the horizontal direction can be limited by the movable groove 12111 to achieve synchronous horizontal movement when moving.

[0093] Furthermore, the release device 2 also includes an annular propulsion portion 23;

[0094] The propulsion portion is disposed on a side of the movable plate 21 facing away from the base plate 11 , and the propulsion portion is disposed on each of the unit holes 221 of the movable plate 21 .

[0095] As mentioned above, the annular propulsion portion 23 is disposed on each unit hole 221 and extends toward the suction head 400 relative to the movable plate 21 of the release device 2 , so as to better push away the tail end of the suction head 400 .

[0096] For further reference, Fig.10 , the tip extractor 100 further includes a handle device 4;

[0097] The handle device 4 includes a connecting shaft 41, an upper handle portion 42, an upper movable rod 43, a lower handle portion 44 and a lower movable rod 45;

[0098] The upper movable rod 43 and the lower movable rod 45 are hingedly connected via the connecting shaft 41;

[0099] One end of the upper movable rod 43 is connected to the upper handle portion 42, and the other end is connected to the plug-in device 1;

[0100] One end of the lower movable rod 45 is connected to the lower handle portion 44, and the other end is connected to the release device 2;

[0101] When the upper handle portion 42 and the lower handle portion 44 move toward each other, the distance between the upper movable rod 43 and the lower movable rod 45 is expanded through the connecting shaft 41 , and the release device 2 is driven away from the plug device 1 .

[0102] As mentioned above, in order to improve the convenience during operation, in the present invention, a handle device 4 is provided on the suction tip extractor 100 to control the activities between the plug-in device 1 and the release device 2 through the handle device 4 .

[0103] The upper movable rod 43 and the lower movable rod 45 are hinged via the connecting shaft 41 , and the upper movable rod 43 and the lower movable rod 45 can move relative to each other via the connecting shaft 41 .

[0104] One end of the upper movable rod 43 is connected to the upper handle portion 42 , and the other end is connected to the plug-in device 1 ; one end of the lower movable rod 45 is connected to the lower handle portion 44 , and the other end is connected to the release device 2 .

[0105] Due to the lever action of the connecting shaft 41, when the upper handle portion 42 is pressed downward, an upward force is given, causing the upper handle portion 42 to drive the base plate 11 of the plug-in device 1 to move upward; and when the lower handle portion 44 is lifted upward, a downward force is given, which also causes the lower handle portion 44 to drive the release device 2 to move downward.

[0106] When in use, the operator only needs to operate the upper handle portion 42 and the lower handle portion 44. When the suction head 400 needs to be released, the upper handle portion 42 and the lower handle portion 44 are moved toward each other to close the distance between the two handles. Due to the lever action of the connecting shaft 41, an upward force is exerted on the plug-in device 1 and a downward force is exerted on the release device 2, so that the release device 2 can move relative to the plug-in device 1 and away from the plug-in device 1, thereby achieving the release of the suction head 400.

[0107] As mentioned above, the connecting shaft 41 can be set in the space between the plug device 1 and the release device 2. The upper movable rod 43 can be connected to the middle, middle position or any position of the sides of the base plate 11 of the plug device 1. In order to achieve the stability of movement, it can be set in the middle position connected to the base plate 11. Similarly, the lower movable rod 45 can also be set in the middle position of the movable plate 21.

[0108] The handle device 4 can be provided with one group, or can be provided with multiple groups for the convenience of operation. For example, at the symmetrical positions of the two ends of the tip extractor 100, one group of handle devices 4 is provided respectively, and the two groups of handle devices 4 are operated simultaneously. On the one hand, it is convenient to hold, more stable, and efficient. On the other hand, operating the two ends simultaneously further improves the stability of the movement of the release device and avoids the problem of one side being higher than the other side.

[0109] Furthermore, a first elastic connecting member 46 connected to both the upper handle portion 42 and the lower handle portion 44 is provided between the upper handle portion 42 and the lower handle portion 44;

[0110] A second elastic connector 3 connected to both the plug-in device 1 and the release device 2 is provided between the plug-in device 1 and the release device 2 .

[0111] As mentioned above, the first elastic connector 46 between the upper handle portion 42 and the lower handle portion 44, and the second elastic connector 3 between the plug-in device 1 and the release device 2 can generate a certain traction force between the upper handle portion 42 and the lower handle portion 44, and between the plug-in device 1 and the release device 2. When operating, the upper and lower parts are pulled in or away from each other, and then the upper and lower parts rebound quickly and return to their original positions, thereby improving the convenience of operation.

[0112] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
