Description

Technical Field

[0001] This utility model belongs to the field of pipette holder technology, and in particular relates to a pipette holder for medical testing. Background Technology

[0002] In fields such as medical testing, molecular biology, and drug development, pipettes are indispensable precision instruments used to accurately measure and transfer minute amounts of liquid. For ease of operation and management, laboratories are typically equipped with dedicated pipette stands to centrally store and support multiple pipettes.

[0003] In existing technologies, a common solution for protecting pipettes from dust and impacts is to install a fixed transparent plastic cover on the outside of the pipette holder. However, while such covered pipette holders provide protection, they compromise ease of operation. Operators must manually open or remove the protective cover each time they pick up or put back the pipette. This extra step is particularly cumbersome in high-throughput experiments requiring frequent, multi-batch pipetting operations, leading to reduced work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a pipette holder for medical testing, which improves the convenience of picking up and putting away pipettes under protection to a certain extent.

[0005] The aforementioned medical testing pipette holder includes a chassis, a support tube vertically fixed to the top of the chassis, a support frame for supporting the pipette at the upper end of the support tube, a lifting assembly for raising and lowering the support frame inside the support tube, and a protective sleeve for protecting the pipette mounted on the chassis. The lifting assembly includes an inner liner, which is independently installed inside the support tube. A first spring is installed between the lower end of the inner liner and the chassis to push the inner liner upward. A through groove communicating with the inside is formed on the side wall of the inner liner. A latch is hinged in the through groove, and a locking groove for locking the latch is opened on the inner side wall of the chassis; a movable rod is independently installed in the inner bushing, and a first drive head is fixed at the lower end of the movable rod to push the locking end of the latch out of the locking groove; the upper end of the movable rod passes out of the inner bushing and is located on its outside; the lower end of the first drive head is connected to a second drive head to push the locking end of the latch into the locking groove; a second spring is installed between the second drive head and the inner bottom of the inner bushing to push the second drive head to move upward.

[0006] Pressing the upper end of the movable rod pushes the first drive head to disengage the locking end of the buckle from the locking groove. After the inner liner is disengaged from the support tube, it is pushed up by the first spring. The support frame then drives all the pipettes to extend out of the protective sleeve for easy access.

[0007] Furthermore, the support frame includes a rotating sleeve, the upper end of the inner liner protruding from the support tube and independently installed inside the rotating sleeve, and several gunstocks for suspending pipettes are fixed on the outer wall of the rotating sleeve; two retaining rings are fitted on the inner liner to restrict the up and down movement of the rotating sleeve.

[0008] The pipette's tail hook is attached to the stock, thus supporting the pipette. The rotating sleeve can rotate freely, making it convenient to access the pipette on the other side after rotation.

[0009] Furthermore, a connecting plate is fixed to the outer wall of the rotating sleeve, and a support is fixed to the other end of the connecting plate to limit the shaking of the pipette.

[0010] The support has a limiting groove to restrict the pipette's movement. The pipette body can be embedded in the limiting groove to prevent it from shaking, thereby improving its stability. The connecting plate increases the distance between the support and the pipette holder. By limiting the pipette through two fulcrums, the stability can be effectively improved. The outer diameter of the rotating sleeve is larger than the outer diameter of the support tube. When the connecting plate is fixed to the outer wall of the rotating sleeve, the lowering of the inner liner will not cause interference between the connecting plate and the support tube.

[0011] Furthermore, the protective sleeve is made of a transparent material.

[0012] The transparent protective sleeve makes it easy to observe the placement of the pipettes inside.

[0013] Furthermore, a fixing ring is fitted onto the movable rod, and a limiting ring is fixed to the upper end of the support tube to restrict the upward movement of the fixing ring.

[0014] The limiting ring and the fixed ring cooperate to constrain the upward movement of the movable rod, so that the second drive head is just behind the locking end of the buckle, thereby pushing the locking end of the buckle into the lock groove.

[0015] Furthermore, a pressing head is fixed to the upper end of the movable rod.

[0016] The pressing head increases the contact area, making it easier for operators to press the movable rod.

[0017] Furthermore, a cover plate is fixed to the upper end of the movable rod, and the side wall of the cover plate is in contact with the inner side wall of the protective sleeve.

[0018] The cover plate further seals the inside of the protective sleeve, improving the protective effect. Pressing the cover plate also presses the movable rod.

[0019] Furthermore, a portal frame with a "door" shaped structure is provided directly above the cover plate. Two through holes are provided on the cover plate, and the two legs of the portal frame pass through the two through holes and are fixed to the upper end of the inner liner.

[0020] To lower the inner liner, the force needs to be transferred to the inner liner through the gantry frame. If the cover plate is pressed to lower the inner liner, the buckle and locking groove will not be able to lock.

[0021] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a lifting assembly to raise the support frame holding the pipette from inside the protective sleeve, making it convenient to use and store, and improving the ease of operation to a certain extent.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0024] Example 1 This embodiment describes a pipette holder for medical testing, such as... Figures 1 to 3 As shown, it includes a chassis 1, a support tube 3 is vertically fixed on the top of the chassis 1, and a support frame for supporting the pipette is provided at the upper end of the support tube 3.

[0025] The support tube 3 is equipped with a lifting component for raising and lowering the support frame. The chassis 1 is equipped with a protective sleeve 4 for protecting the pipette. The protective sleeve 4 is made of transparent acrylic material, which makes it easy to observe the status of the pipette inside.

[0026] The lifting assembly includes an inner sleeve 13, which is independently installed inside the support tube 3 and can slide up and down. A first spring 2 is installed between the lower end of the inner sleeve 13 and the chassis 1 to push the inner sleeve 13 upward. In the natural state, the elastic force of the first spring 2 pushes the inner sleeve 13 to move upward.

[0027] The inner liner 13 has a through groove on its side wall that connects the inside and outside, and a snap fastener 15 is hinged in the through groove. During production, two symmetrically distributed snap fasteners 15 can be set to lock symmetrically onto the support tube 3 to improve the locking strength.

[0028] The middle part of the latch 15 is hinged in the through groove by a pin, and the latch 15 can rotate around the pin. A locking groove is provided on the inner side wall of the chassis 1 for locking the locking end of the latch 15. Rotating the latch 15 allows its locking end to enter the through groove, locking the inner sleeve 13 to the support tube 3 and preventing the first spring 2 from pushing the inner sleeve 13 upwards. When the locking end of the latch 15 is locked in the locking groove, the first spring 2 is in a compressed state.

[0029] An independent movable rod 7 is installed inside the inner sleeve 13. A first driving head 14 is fixed to the lower end of the movable rod 7, pushing the locking end of the latch 15 out of the lock groove. The first driving head 14 has a truncated cone structure that is narrower at the bottom and wider at the top, making its sidewalls inclined, directly facing the inner side of the driving end (the other end of the locking end) of the latch 15. In use, when the first driving head 14 moves downward, its narrower-at-the-bottom and wider-at-the-top structure squeezes the driving end of the latch 15 to swing outwards. The locking end of the latch 15 then rotates around the pin and swings inwards, disengaging from the lock groove and re-establishing the locking relationship between the inner sleeve 13 and the support tube 3.

[0030] The upper end of the movable rod 7 extends out of the inner sleeve 13 and is located on its outside; a pressing head 8 is fixed to the upper end of the movable rod 7 for easy pressing by the operator.

[0031] The lower end of the first drive head 14 is connected to a second drive head 6 that pushes the locking end of the buckle 15 into the lock groove. The second drive head 6 is opposite to the first drive head 14. It has a truncated cone structure that is narrow at the top and wide at the bottom, so that its side wall is also inclined. It faces the inner side of the locking end of the two buckles 15. When the second drive head 6 rises, the inclined surface of the second drive head 6 squeezes the locking end of the buckle 15 and swings it outward, so that it enters the lock groove, thereby realizing the locking function between the inner bushing 13 and the support tube 3.

[0032] A second spring 5 is installed between the second drive head 6 and the inner bottom of the inner bushing 13 to push the second drive head 6 upward. The elastic force of the second spring 5 continuously pushes the second drive head 6 and the first drive head 14 upward to reset. The second drive head 6 and the first drive head 14 are connected by a connecting post. In the natural state, the second drive head 6 is located between the locking ends of the two latches 15, providing a force to push the locking ends of the latches 15 to swing outward.

[0033] Conversely, pressing the pressing head 8 causes the second driving head 6 and the first driving head 14 to move downwards simultaneously under the action of the movable rod 7. The second spring 5 is compressed, and the first driving head 14 descends between the driving ends of the two latches 15, pushing the driving ends of the latches 15 to swing outwards. Meanwhile, the second driving head 6 moves downwards along with the first driving head 14, moving away from the inside of the locking ends of the two latches 15 to avoid interference with the driving ends of the latches 15 that are about to swing inwards. Thus, the first driving head 14 completes the unlocking and dislocking of the latches 15 from the lock groove.

[0034] Release the pressing head 8, the second spring 5 returns to its original position, and the second drive head 6 enters between the locking ends of the two latches 15. The first drive head 14 moves upward and pushes out from the drive ends of the two latches 15 to avoid interference with the drive ends of the latches 15. When the locking end of the latch 15 is aligned with the lock groove, the thrust provided by the second drive head 6 causes the locking end of the latch 15 to enter the lock groove, completing the locking between the inner bushing 13 and the support tube 3.

[0035] A retaining ring is fitted onto the movable rod 7, and a limiting ring 17 is fixed to the upper end of the support tube 3 to restrict the upward movement of the retaining ring. This is used to limit the excessive upward movement of the retaining ring and the movable rod 7, ensuring that in the non-pressed state, the second drive head 6 is just inside the locking end of the buckle 15 under the action of the second spring 5, forcing its locking end to pop outward and engage in the locking groove of the support tube 3, thereby achieving locking.

[0036] The support frame includes a rotating sleeve 10. The upper end of an inner liner 13 extends through a support tube 3 and is independently installed inside the rotating sleeve 10. Several gun supports 9 for suspending pipettes are fixed on the outer wall of the rotating sleeve 10. Two retaining rings 16 are fitted on the inner liner 13 to restrict the vertical movement of the rotating sleeve 10. Eight gun supports 9 are fixed on the outer wall of the rotating sleeve 10 and are evenly spaced along its circumference. The structure of the gun supports 9 can refer to the structure of gun supports 9 on existing rotatable supports. It is an accessory to existing components. In use, the tail hook of the pipette can be suspended on the gun support 9, and the tip of the pipette stands vertically downward.

[0037] The rotating sleeve 10 can rotate freely, making it convenient for staff to access the pipette on the back of the rotating sleeve 10. The retaining ring 16 is used to restrict the up and down movement of the rotating sleeve 10, so that it can only rotate freely in place.

[0038] A connecting plate 11 is fixed to the outer wall of the rotating sleeve 10, and a support 12 is fixed to the other end of the connecting plate 11 to limit the swaying of the pipette. To further improve stability, the support 12 restricts the pipette body, reduces its swaying, and improves its stability. The connecting plate 11 increases the distance between the pipette stock 9 and the support 12, which can be used to better maintain the stability of the pipette when it is supported.

[0039] In actual use: like Figure 1 As shown, under the action of the second spring 5, the second drive head 6 pushes upward against the locking end of the buckle 15, causing its locking end to engage in the locking groove of the support tube 3, and the inner liner 13 is locked relative to the support tube 3. At this time, the entire support frame and the suspended pipette are located inside the protective sleeve 4 and are in a protected state.

[0040] When a pipette is needed, press the pressing head 8 with your finger. The movable lever 7 moves downward, causing the first drive head 14 to press down on the inner side of the drive end of the latch 15. The latch 15 rotates around the hinge point, and its locking end retracts inward, disengaging from the locking groove of the support tube 3. Once unlocked, the inner sleeve 13 moves rapidly upward under the push of the first spring 2, causing the rotating sleeve 10, the pipette stock 9, and all the pipettes to rise together. The pipette tip then extends from the protective sleeve 4, making it easy for the operator to pick up and store. At this time, the operator can also easily rotate the rotating sleeve 10 to conveniently pick up pipettes in different positions. In addition, the inner sleeve 13 maintains pressure on the pressing head 8 during its ascent to prevent the inner sleeve 13 from rising too quickly and ejecting the pipette.

[0041] Two symmetrically arranged limiting blocks are fixed on the inner wall of the upper end of the support tube 3. Two sliding grooves (avoiding the latch 15) are provided on the outer wall of the inner sleeve 13. The sliding grooves and limiting blocks slide vertically together, preventing the inner sleeve 13 from rotating and causing the latch 15 to deviate from its original position and no longer be on the same plane as the locking groove, thus preventing successful locking. Additionally, the limiting blocks also prevent the inner sleeve 13 from slipping out of the support tube 3 under the push of the first spring 2. After use, press the upper end of the support tube 3, being careful to avoid pressing the pressing head 8. If the pressing head 8 is pressed, even if the inner sleeve 13 enters the support tube 3, the latch 15 will not lock with the locking groove. Pressing the support tube 3 overcomes the force of the first spring 2, pushing the entire support frame back into the protective sleeve 4. When the latch 15 moves down to the position aligned with the lock groove, the second drive head 6 will force the locking end of the latch 15 to pop out again and lock into the lock groove, restoring the locked protection state, while the pipette on the support frame is protected inside the sleeve (4).

[0042] Example 2: like Figure 4 As shown, this embodiment is described in conjunction with Embodiment 1, the difference being that the pressing head 8 is omitted, and instead a cover plate 18 is fixed to the upper end of the movable rod 7. The diameter of the cover plate 18 is adapted to the inner diameter of the protective sleeve 4, and its sidewall is tightly fitted to the inner sidewall of the protective sleeve 4.

[0043] The cover plate 18 facilitates pressing the movable rod 7, and in the protective state, it can seal the upper port of the protective sleeve 4 to form a more sealed protective space, further preventing dust and moisture, and improving the protective effect.

[0044] Additionally, a portal frame 19, independent of and shaped like a "door," is positioned directly above the cover plate 18. The cover plate 18 has two through holes that connect vertically. Two legs of the portal frame 19 pass through these two through holes and are fixed to the upper end of the inner sleeve 13. When the cover plate 18 is pressed, the force is transmitted to the movable rod 7, which releases the lock between the buckle 15 and the locking groove. Pressing the portal frame 19 avoids the cover plate 18; in this case, the force is transmitted through the portal frame 19 to the inner sleeve 13, causing the inner sleeve 13 to enter the support tube 3. If the cover plate 18 is pressed, causing the inner sleeve 13 to descend, the buckle 15 and the locking groove cannot lock.
