Description

Technical Field

[0001] This application relates to the field of pipette tip technology, specifically a detachable pipette tip. Background Technology

[0002] Pipette tips are indispensable consumables in biological laboratories, used for the accurate transfer and dispensing of liquid samples. Choosing the right tip is crucial to ensuring the accuracy of experimental results, the integrity of samples, and the lifespan of the pipette. The tip is inserted into the pipette via a plug-in connection, and a sealing ring on the inner wall of the tip increases the contact area with the pipette, effectively preventing it from falling off and ensuring a good seal.

[0003] Different types of pipettes can accommodate a different number of tips. When dealing with pipettes that can accommodate a large number of tips, each tip needs to be removed individually for replacement. This process needs to be repeated several times before all the tips on the pipette can be removed. This method is quite time-consuming. Utility Model Content

[0004] The purpose of this application is to provide a detachable pipette tip to solve the problem mentioned in the background art that when dealing with pipettes that can accommodate a large number of tips, each tip needs to be removed individually and the process repeated multiple times before all the tips on the pipette can be removed. This method is time-consuming.

[0005] To achieve the above objectives, this application provides the following technical solution: a detachable pipette tip, comprising: a pipette tip body, a sealing ring, a fixing connection mechanism, and a clamping and positioning mechanism. The accessory body includes the pipette tip body and a sealing ring adhered to the inner wall of the pipette tip body. The fixing connection mechanism is disposed outside the pipette tip body and includes a connecting shaft disposed outside the pipette tip body, a first positioning block rotatably connected to the connecting shaft at one end, and a second positioning block rotatably connected to the connecting shaft at the other end. The pipette tip body is disposed inside the first positioning block and the second positioning block, a first connecting block disposed at the other end of the first positioning block, and a plug-in block disposed at the other end of the second positioning block. The clamping and positioning mechanism is disposed on the outer wall of the first positioning block and the second positioning block.

[0006] By adopting the above technical solution, it is possible to connect multiple sets of pipette tip bodies, thereby enabling simultaneous removal in the future.

[0007] Preferably, one side of the inner wall of the first positioning block and the second positioning block is provided with an arc-shaped groove that matches the outer diameter of the pipette tip body.

[0008] By adopting the above technical solution, the pipette tip body can be stably placed inside the first positioning block and the second positioning block.

[0009] Preferably, the fixed connection mechanism further includes an elastic anti-slip block disposed on the inner wall of the arc-shaped groove of the first positioning block and the second positioning block, the elastic anti-slip block being attached to the outer wall of the pipette tip body.

[0010] By adopting the above technical solution, the pipette tip body located inside the first positioning block and the second positioning block can provide effective stability.

[0011] Preferably, the cross-sectional shape of the plug-in block is "U", and the first connecting block engages inside the plug-in block.

[0012] By adopting the above technical solution and using a snap-fit ​​connection, the connection and fixation of the first positioning block and the second positioning block are provided, thereby connecting the multiple sets of pipette tip bodies inside the first positioning block and the second positioning block.

[0013] Preferably, the clamping and positioning mechanism includes a second connecting block with one end disposed on the outer wall of the first positioning block and the second positioning block, and the second connecting block is made of elastic plastic material.

[0014] By adopting the above technical solution, deformation can be generated to achieve subsequent clamping and fixation on both sides of the outer wall of the pipette.

[0015] Preferably, the clamping and positioning mechanism further includes a positioning block disposed at the other end of the second connecting block.

[0016] By adopting the above technical solution, it can fit against both sides of the outer wall of the pipette, thereby achieving clamping through the second connecting block.

[0017] Preferably, a rubber anti-slip pad is provided on the outer wall of the positioning block.

[0018] By adopting the above technical solution, the positioning blocks that adhere to both sides of the outer wall of the pipette can effectively prevent slippage.

[0019] In summary, this application has the following beneficial effects: by providing a fixed connection mechanism and a clamping and positioning mechanism, multiple sets of pipette tip bodies can be quickly connected, so that when removing them from the pipette, it is not necessary to remove them one by one. By connecting them, when removing one, all of them can be removed at the same time, which improves the time required to remove the pipette tip bodies. In addition, the clamping and positioning mechanism can clamp onto the outer wall of the pipette, providing better stability to the fixed connection mechanism inside the fixed connection mechanism.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0027] Example 1

[0028] Please see Figures 1-4 This embodiment provides a technical solution: a detachable pipette tip, comprising: a pipette tip body 1, a sealing ring 2, a fixing connection mechanism 3, and a clamping and positioning mechanism 4;

[0029] The main components of the accessory include the pipette tip body 1 and a sealing ring 2 attached to the inner wall of the pipette tip body 1. The pipette tip body 1 is an indispensable consumable in biological laboratories, used for the accurate transfer and dispensing of liquid samples. Selecting a suitable pipette tip body 1 is crucial for ensuring the accuracy of experimental results, the integrity of samples, and the lifespan of the pipette. The above is existing technology and will not be elaborated further below.

[0030] A fixed connection mechanism 3 is disposed on the outside of the suction head body 1. The fixed connection mechanism 3 includes a connecting shaft 301 disposed on the outside of the suction head body 1, a first positioning block 302 rotatably connected to the connecting shaft 301 at one end, and a second positioning block 303 rotatably connected to the connecting shaft 301 at the other end. The suction head body 1 is disposed inside the first positioning block 302 and the second positioning block 303. A first connecting latch 305 is disposed at the other end of the first positioning block 302, and a plug-in block 306 is disposed at the other end of the second positioning block 303. The first positioning block 302 and The inner wall of the second positioning block 303 is provided with an arc-shaped groove that matches the outer diameter of the pipette tip body 1. The fixed connection mechanism 3 also includes an elastic anti-slip block 304 provided on the inner wall of the arc-shaped groove of the first positioning block 302 and the second positioning block 303. The elastic anti-slip block 304 is attached to the outer wall of the pipette tip body 1. The cross-sectional shape of the insertion block 306 is "U" shaped, and the first connecting block 305 is engaged inside the insertion block 306. The clamping and positioning mechanism 4 is provided on the outer wall of the first positioning block 302 and the second positioning block 303.

[0031] The pipette tip body 1 can be inserted into the pipette, thereby achieving a connection through insertion. During insertion, the inner wall of the pipette tip body 1 is connected to the pipette through the sealing ring 2, which increases the friction between the pipette tip body 1 and the pipette, thereby achieving an effective sealing effect after insertion.

[0032] When multiple pipette tip bodies 1 can be installed on a pipette, the fixing connection mechanism 3 can connect the multiple pipette tip bodies 1 into a whole. When it is necessary to remove the pipette tip bodies 1 from the pipette in the future, after one removal action, all the pipette tip bodies 1 on the pipette can be removed at the same time. Furthermore, the clamping and positioning mechanism 4 can clamp and fix the fixing connection mechanism 3 and the multiple pipette tip bodies 1 inside to the outer wall of the pipette to achieve effective fixing connection.

[0033] Multiple sets of pipette tip bodies 1 are placed inside multiple sets of arc-shaped grooves opened on the inner walls of the first positioning block 302 and the second positioning block 303. At this time, the first positioning block 302 and the second positioning block 303 rotate through the connecting shaft 301. The first positioning block 302 and the second positioning block 303 can fit against the outer wall of the pipette tip body 1. The elastic anti-slip block 304 on the inner wall of the first positioning block 302 and the second positioning block 303 can fit precisely against the outer wall of the pipette tip body 1, which provides stability to the pipette tip body 1 on the inner wall of the first positioning block 302 and the second positioning block 303. At this time, the other end of the first positioning block 302 and the second positioning block 303 is inserted into the inside of the insertion block 306 through the first connecting block 305, thereby achieving a fixed connection between the first positioning block 302 and the second positioning block 303.

[0034] Example 2

[0035] Please see Figures 1-4 This embodiment provides a technical solution: a detachable pipette tip, including: a second connecting block 401 and a positioning block 402;

[0036] The clamping and positioning mechanism 4 includes a second connecting block 401 with one end disposed on the outer wall of the first positioning block 302 and the second positioning block 303. The second connecting block 401 is made of elastic plastic. The other end of the second connecting block 401 is a positioning block 402 with a rubber anti-slip pad on its outer wall.

[0037] When it is necessary to fix the first positioning block 302 and the second positioning block 303 to the outer wall of the pipette, the positioning block 402 is attached to the outer wall of the pipette by the deformation of the second connecting block 401, thereby achieving an effective fixing effect.

[0038] The implementation principle of the detachable pipette tip of this application is as follows:

[0039] First, the pipette tip body 1 can be inserted into the pipette, thus achieving a connection through insertion. During insertion, the inner wall of the pipette tip body 1 is connected to the pipette through the sealing ring 2, thereby increasing the friction between the pipette tip body 1 and the pipette and achieving an effective sealing effect after insertion.

[0040] Secondly, when multiple pipette tip bodies 1 can be installed on the pipette, the fixing connection mechanism 3 can connect the multiple pipette tip bodies 1 into a whole. When it is necessary to remove the pipette tip bodies 1 from the pipette in the future, after one removal action, all the pipette tip bodies 1 on the pipette can be removed at the same time. Furthermore, the clamping and positioning mechanism 4 can clamp and fix the fixing connection mechanism 3 and the multiple pipette tip bodies 1 inside to the outer wall of the pipette to achieve effective fixing connection.

[0041] Finally, multiple sets of pipette tip bodies 1 are placed inside multiple sets of arc-shaped grooves opened on the inner walls of the first positioning block 302 and the second positioning block 303. At this time, the first positioning block 302 and the second positioning block 303 rotate through the connecting shaft 301. At this time, the first positioning block 302 and the second positioning block 303 can fit against the outer wall of the pipette tip body 1, and the elastic anti-slip blocks 304 on the inner walls of the first positioning block 302 and the second positioning block 303 can precisely fit against the outer wall of the pipette tip body 1, so that the pipette tip body 1 can play a role in the first positioning block 302 and the second positioning block 303. The stability of the inner walls of the first positioning block 302 and the second positioning block 303 is achieved by inserting the other ends of the first positioning block 302 and the second positioning block 303 into the inside of the insertion block 306 through the first connecting block 305, thereby achieving a fixed connection between the first positioning block 302 and the second positioning block 303. When it is necessary to fix the first positioning block 302 and the second positioning block 303 to the outer wall of the pipette, the deformation of the second connecting block 401 will cause the positioning block 402 to adhere to the outer wall of the pipette, thereby achieving an effective fixing effect.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
