Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and more specifically to a self-replenishing support mechanism, a self-replenishing storage device for consumables, and a storage box. Background Technology

[0002] In the fields of chemical and biological experiments, pipette tips are consumables used in laboratories for the precise transfer of liquids. They are typically made of polypropylene (PP), which has good chemical stability and biocompatibility. Currently, commercially available pre-filled disposable pipette tip boxes are available on the market. The design of these boxes improves ease of use to some extent. Each box contains a shelf with pre-filled pipette tips, and the entire box is sealed and sterilized. When in use, researchers can simply remove the seal, open the box, and quickly and easily access the pipette tips. This design is convenient and meets the basic needs of researchers when the amount used in a single experiment is small.

[0003] However, with the development of experimental technology and the expansion of experimental scale, the demand for pipette tips in laboratories is also increasing. Experimenters need to frequently change pipette tips. Using this disposable pipette tip box, only a single layer of pipette tip can be used each time it is disassembled and assembled, which cannot meet the needs of large-scale use and also has a serious waste problem. In experiments that need to be carried out in limited spaces such as clean benches, a large number of disposable pipette tip boxes are piled up on the workbench, which seriously affects the operating range of experimenters and reduces the utilization efficiency of laboratory space.

[0004] Therefore, the problems of serious waste, large space occupation, and inconvenience in replenishing consumable storage devices in the existing technology urgently need to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a self-replenishing support mechanism, a self-replenishing storage device for consumables, and a storage box, aiming to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-sustaining support mechanism includes a support assembly comprising a support rod, a limiting plate, and a telescopic drive component. In normal operation, the support rod is vertically arranged along the direction of gravity. The limiting plate is fixed to the top of the support rod, and the telescopic drive component is fixed to the bottom of the support rod. The limiting plate and the telescopic drive component are located on the same side of the support rod. The telescopic drive component has a free end capable of extending and retracting vertically, the free end having an upward driving force and forming a clamping space with the limiting plate.

[0008] Preferably, in the above-mentioned self-reinforcing support mechanism, the telescopic drive component is an elastic telescopic element; the elastic telescopic element is a gas spring. The gas spring provides a stable elastic thrust, ensuring that the shelf can rise smoothly and avoiding unstable or damaged shelf rise due to insufficient or excessive elasticity; the gas spring can be adjusted according to different loads and usage requirements, enhancing the adaptability of the device and making it suitable for consumables of different specifications and weights.

[0009] This utility model discloses a self-replenishing storage device for consumables, including at least two self-replenishing support mechanisms and horizontally arranged shelves into which consumables are inserted. Support rods are arranged on opposite sides of the shelves, and the shelves are clamped and fixed in the clamping space. When there are two or more shelves, the shelves are stacked on top of each other.

[0010] Through the above technical solution, this utility model provides a consumable self-replenishing storage device including a self-replenishing support mechanism. The upward driving force of the telescopic drive component and the blocking effect of the limiting plate jointly clamp and fix the shelves in the clamping space. When there are multiple shelves, after the consumables in the top shelf are used up, the shelf is slid out along the side without support rods. Under the driving force of the telescopic drive component, the remaining shelves automatically rise. At this time, the top shelf can be stopped at a predetermined position by the blocking effect of the limiting plate, ensuring that one layer of consumables is accurately provided each time it is used. This utility model achieves automatic lifting and precise positioning of the shelves through the cooperation of the driving force of the telescopic drive component and the blocking effect of the limiting plate, ensuring a continuous supply of consumables, reducing manual replenishment operations, and improving experimental efficiency. At the same time, the multi-layer shelf structure is compact, making full use of vertical space and adapting to the storage needs of consumables of different heights.

[0011] Preferably, in the above-mentioned self-replenishing storage device for consumables, a plug-in rod is fixed to the top of the free end of the telescopic drive component, and a plug-in hole corresponding to the plug-in rod is opened on the bottom surface of the shelf. The plug-in structure assists in the rapid positioning of the shelf, improving assembly efficiency; the cooperation between the plug-in rod and the plug-in hole prevents the shelf from sliding or misaligning, enhancing the reliability of the connection between the shelf and the telescopic drive component.

[0012] Preferably, the above-mentioned self-replenishing storage device for consumables further includes a one-way limiting block. The one-way limiting block is disposed on the side wall of the support rod, located between the limiting plate and the telescopic drive member, and has a wedge-shaped protrusion on the same side as the telescopic drive member. The support rod has a cavity that can accommodate the deformation and / or displacement of the one-way limiting block. A wedge-shaped groove that mates with the wedge-shaped protrusion is formed on the side wall of the shelf. When the shelf above the wedge-shaped groove contacts the wedge-shaped protrusion, the wedge-shaped protrusion is forced to retract into the cavity. When the top surface of the shelf abuts against the bottom wall of the limiting plate, the wedge-shaped protrusion engages with the wedge-shaped groove, thereby preventing the shelf from moving downward. When the shelf moves / rises along the support rod from bottom to top and comes into contact with the one-way limiting block, the shelf exerts a squeezing force on the one-way limiting block, causing it to deform and / or displace away from the shelf. This causes the wedge-shaped protrusion to retract into the cavity on the support rod, allowing space for the shelf to continue rising. When the shelf reaches the predetermined position, and the top surface of the uppermost shelf abuts against the bottom wall of the limiting block, the one-way limiting block is released and restored. The wedge-shaped protrusion is then embedded in the wedge-shaped groove, achieving one-way locking of the shelf. At this time, the one-way limiting block prevents the shelf from falling downwards, further fixing the shelf's position and preventing it from shifting during use. This is especially effective in preventing shelf shaking when pressing the pipette tip. At the same time, the one-way limiting block and the wedge-shaped groove act like a guide rail, making it easier to slide the shelf out laterally.

[0013] Preferably, the unidirectional limiting block adopts a unidirectional snap-fit ​​structure, consisting of an elastic arm and a hook-shaped buckle at its free end: the elastic arm is arranged axially along the support rod and embedded in the support rod, one end of the elastic arm is fixedly connected to the support rod, and the other end is a free end with a hook-shaped buckle on the same side as the telescopic drive component. The wedge-shaped tip of the hook-shaped buckle protrudes from the outer edge of the support rod and engages with the wedge-shaped groove on the side of the shelf; during the process of the telescopic drive component pushing the shelf upward along the support rod, when the part of the shelf above the wedge-shaped groove contacts the wedge-shaped tip, the shelf generates a squeezing force that drives the elastic arm to elastically deform away from the shelf, thereby driving the buckle to move and making room for the shelf to rise; the shelf continues to move upward until the upper edge of the shelf abuts the bottom surface of the limiting plate, the side of the shelf disengages from the buckle, the elastic arm drives the buckle to automatically reset, so that the wedge-shaped tip is embedded in the wedge-shaped groove, forming a pre-lock; when the shelf is subjected to a downward force, the buckle that abuts the wedge-shaped groove blocks the shelf displacement, realizing mechanical locking. The one-way snap-fit ​​structure is simple, safe and reliable, and can further secure the shelves.

[0014] Preferably, in the above-mentioned self-replenishing consumable storage device, the number of support rods is even, symmetrically arranged on both sides of the shelf. The symmetrically arranged support mechanism improves the overall stability of the device, ensuring that the device will not tilt or shake due to uneven force during use; it ensures that the shelf is subjected to uniform force during ascent, avoiding shelf jamming or damage due to uneven force, thus improving the reliability and service life of the device; the design of multiple support mechanisms enhances the overall structural strength of the device, enabling it to withstand greater loads and improving the safety and stability of the device.

[0015] This utility model also provides a self-replenishing storage box for consumables, including a box body and the aforementioned self-replenishing storage device for consumables placed inside the box body; the box body includes a box frame and a box lid hinged to the box frame; the lower edge of the uppermost shelf is flush with the upper edge of the box frame. The box body design allows the entire device to be reused multiple times, reducing resource waste, lowering experimental costs, and conforming to environmental protection principles; the hinge and snap-fit ​​of the box lid and box frame provide good sealing performance, preventing consumables from being contaminated and ensuring the accuracy of the experiment; integrating the self-replenishing storage device for consumables with the box body forms a complete system, improving the practicality and convenience of the device; the box lid and box frame have sufficient capacity to avoid squeezing consumables when closed (such as the top of the consumable protruding), protecting the integrity of the consumables.

[0016] Preferably, the aforementioned self-replenishing consumable storage box further includes a wedge and a spring. The wedge-shaped end of the wedge is fixedly connected to the side wall of the support rod away from the telescopic drive component, while the other end is a free end extending upwards. The spring connects the support rod and the wedge, and the wedge abuts against the box body under the action of the spring. This structure provides an elastic adjustment function, ensuring the stability of the device within the box and preventing damage to the device or displacement of consumables due to shaking. The wedge can be finely adjusted according to the size of the box, enhancing the adaptability of the device and making it suitable for different box sizes. The elasticity of the spring buffers the impact force between the support rod and the box body, reducing damage caused by external forces and improving the durability of the device.

[0017] Preferably, in the aforementioned self-replenishing consumable storage box, longitudinal guide ribs are provided on the side wall of the box body. These guide ribs partially accommodate the support rod and constrain its position, guiding its movement trajectory. The design of the guide ribs facilitates the installation and removal of the support rod, simplifies the operation steps, and improves the operational efficiency of the experimenter; it ensures the stable placement of the support rod within the box body, preventing shaking or displacement, thus enhancing the overall stability of the device; the guide ribs ensure proper fit between the support rod and the box body, improving the reliability and service life of the device.

[0018] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a self-replenishing support mechanism, a consumable self-replenishing storage device, and a storage box, which have the following beneficial effects:

[0019] 1. This utility model significantly improves experimental efficiency and optimizes space utilization through automatic replenishment function and multi-layer design; the vertical driving force of the telescopic drive component realizes the automatic rise of the shelf layer by layer, reducing the workload of manual replenishment. At the same time, the multi-layer shelf design increases the storage capacity of consumables and improves space utilization, so that the entire device is compactly arranged in the box, saving laboratory space.

[0020] 2. This utility model enhances the stability and reliability of the device through the design of a one-way limiting block. The one-way driving characteristic of the one-way limiting block and its cooperation with the wedge groove realize a one-way locking function, effectively preventing the shelf from shifting and shaking during use, especially when the pipette tip is pressed, ensuring the fixed position of the shelf; the symmetrically arranged support mechanism ensures that the shelf is evenly stressed during the upward movement, avoiding problems such as tilting or jamming.

[0021] 3. This utility model integrates the self-replenishing storage device for consumables with the box body, forming a complete system, which improves the practicality and convenience of the device; the box body and the entire device except for the consumables can be reused multiple times, reducing resource waste, lowering experimental costs, and conforming to the concept of environmental protection.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] See appendix Figure 1 This embodiment discloses a self-supplementing support mechanism, including a support assembly 2. The support assembly 2 includes a support rod 21, a limiting plate 22, and a telescopic drive member 23. The support rod 21 is vertically arranged along the direction of gravity under normal working conditions. The limiting plate 22 is fixed to the top of the support rod 21, and the telescopic drive member 23 is fixed to the bottom of the support rod 21. The limiting plate 22 and the telescopic drive member 23 are located on the same side of the support rod 21. The telescopic drive member 23 has a free end that can extend and retract vertically. The free end has an upward driving force and forms a clamping space 7 with the limiting plate 22.

[0038] To further optimize the above technical solution, the telescopic drive component 23 is an elastic telescopic element; the elastic telescopic element adopts a gas spring; the gas spring can be a NABTESCO gas spring, model: NSK-100.

[0039] See appendix Figure 2-6 This embodiment discloses a self-replenishing storage device for consumables, including at least two self-replenishing support mechanisms and a horizontally arranged shelf 1 in which consumables 11 are inserted. Support rods 21 are arranged on opposite sides of the shelf 1. The shelf 1 is clamped and fixed in the clamping space 7. When there are two or more shelf 1s, the shelf 1s are stacked on top of each other.

[0040] During use, when the consumables 11 in the top shelf 1 are used up, the shelf 1 is slid out along the side without the support rod 21. Under the action of the telescopic drive 23, the remaining shelf 1 rises automatically. At this time, the top shelf 1 can be stopped in the predetermined position by the limit plate 22, ensuring that a layer of consumables can be accurately provided each time it is used.

[0041] To further optimize the above technical solution, multiple evenly distributed placement holes 14 are provided on each layer plate 1, and the consumable 11 can be inserted into the placement holes 14.

[0042] To further optimize the above technical solution, in this embodiment, consumable 11 is a pipette tip. The diameter of the pipette tip's head is larger than the diameter of its tip. This structural feature allows the tips to be stacked layer by layer to form a stable stacked structure. Figure 2 As shown, the tip of the upper pipette tip can be inserted into the cavity of the lower pipette tip, and the bottom surface of the middle layer plate 1 abuts against the head of the pipette tip inserted on the next lower layer plate 1. This design not only realizes the stacking of consumables and increases the storage capacity, but also further enhances the stability of the middle layer plate through the abutment between the head of the pipette tip and the bottom surface of the plate.

[0043] like Figure 2 As shown, the tip of the consumable 11 in the bottommost layer 1 is suspended downwards, and the bottom surface of the middle layer 1 presses against the head of the pipette tip of the lower layer. The tip of the pipette tip of this layer is inserted into the inner cavity of the head of the pipette tip of the lower layer.

[0044] To further optimize the above technical solution, consumable 11 can be a pipette tip, a tubing, an EP tube, or other commonly used laboratory consumables; this design makes the device widely applicable and can meet different experimental needs.

[0045] To further optimize the above technical solution, the material of the shelf 1 is polypropylene (PP) or polystyrene (PS), which has good chemical stability and biocompatibility; the support rod 21 is made of stainless steel or high-strength plastic.

[0046] See appendix Figure 3 and attached Figure 4 In order to further optimize the above technical solution, a plug-in rod 231 is fixed at the top of the telescopic end of the telescopic drive component 23, and a plug-in hole 12 corresponding to the plug-in rod 231 is opened on the bottom surface of the bottom layer plate 1.

[0047] See appendix Figure 5 and attached Figure 6 To further optimize the above technical solution, a one-way limiting block 3 is also included. The one-way limiting block 3 is set on the side wall of the support rod 21, located between the limiting plate 22 and the telescopic drive member 23, and has a wedge-shaped protrusion on the same side as the telescopic drive member 23. The support rod 21 has a cavity to accommodate the deformation and / or displacement of the one-way limiting block 3. A wedge-shaped groove 13 is provided on the side wall of the layer plate 1 to cooperate with the wedge-shaped protrusion. When the layer plate 1 above the wedge-shaped groove 13 contacts the wedge-shaped protrusion, the wedge-shaped protrusion is forcefully contracted into the cavity. When the top surface of the layer plate 1 abuts against the bottom wall of the limiting plate 22, the wedge-shaped protrusion and the wedge-shaped groove 13 are engaged, thereby preventing the layer plate 1 from moving downward.

[0048] To further optimize the above technical solution, the one-way limiting block 3 is a one-way snap-fit ​​structure. The one-way limiting block 3 includes an elastic arm 31 and a hook-shaped buckle 32 located at the free end of the elastic arm 31.

[0049] When the shelf 1 moves / rises along the support rod 21 from bottom to top and comes into contact with the one-way limiting block 3, the shelf 1 exerts a squeezing force on the one-way limiting block 3, causing it to deform and / or displace in a direction away from the shelf 1, thereby contracting into the cavity on the support rod 21, allowing space for the shelf 1 to rise and continue to rise. When the shelf 1 reaches the predetermined position and the top surface of the uppermost shelf 1 abuts against the bottom wall of the limiting plate 22, the one-way limiting block 3 is released and restored, and the wedge-shaped protrusion is embedded in the wedge-shaped groove 13, realizing the one-way locking of the shelf 1. At this time, the one-way limiting block 3 can prevent the shelf 1 from shifting during use, especially when the pipette tip is pressed, it can effectively prevent the shelf 1 from shaking.

[0050] To further optimize the above technical solution, the number of support rods 21 is an even number, and they are symmetrically arranged on both sides of the shelf 1.

[0051] To further optimize the above technical solution, in this embodiment, the number of self-supplementing support mechanisms 2 is four, which are arranged symmetrically in pairs on both sides of the shelf 1.

[0052] See appendix Figure 7 and attached Figure 8This utility model provides a consumable self-replenishment storage box, including a box body 4 and a consumable self-replenishment storage device placed inside the box body 4; the box body 4 includes a box body 41 and a box cover 42 hinged to the box body 41; the box body 41 can accommodate the portion of the consumable self-replenishment storage device located below the bottom edge of the uppermost shelf 1, and the box cover 42 can accommodate the portion of the consumable self-replenishment storage device located above the bottom edge of the uppermost shelf 1.

[0053] See appendix Figure 9 and attached Figure 10 To further optimize the above technical solution, a wedge 5 and a spring 6 are also included. The wedge end 51 of the wedge 5 is fixedly connected to the side wall of the support rod 21 away from the telescopic drive member 23, and the other end is a free end extending upward. The spring 6 is connected between the support rod 21 and the wedge 5. The wedge 5 abuts against the box body 41 under the action of the spring 6.

[0054] To further optimize the above technical solution, longitudinal guide ribs 411 that can partially accommodate the support rod 21 are provided on the side wall of the box body 41.

[0055] The embodiments of this utility model are as follows:

[0056] Initially, the horizontally arranged shelf 1 is clamped between the limiting plate 22 and the telescopic drive member 23. Consumable material 11 is inserted into each shelf 1. When there are two or more shelf 1s, they are stacked vertically. In this embodiment, the number of shelf 1s is three (the specific number of layers can be determined according to actual needs). Figure 11 As shown, when the consumable 11 in the top shelf 1 is used up, the experimenter can slide the shelf 1 laterally along the side without the support rod 21 to remove the shelf 1. Under the upward driving force of the telescopic drive 23, the next shelf 1 automatically rises until its top surface abuts against the bottom wall of the limiting plate 22 and stays in the predetermined position. At this time, the consumable 11 on the shelf 1 is pushed to the use position, ensuring that a layer of consumable 11 can be accurately provided each time it is used. This process is repeated until the consumable 11 in the bottom shelf 1 is used up. Then, the storage device can be disassembled and reassembled with a new shelf 1 containing consumable 11.
