Description

Technical Field

[0001] This invention relates to the field of reagent bottle storage technology, and in particular to an anti-tipping reagent bottle storage rack. Background Technology

[0002] In laboratories of chemistry, biology, and medicine, reagent bottles are the basic containers for storing various chemical reagents, standard solutions, and experimental samples. To ensure a clean and orderly experimental environment and to guarantee operational safety, reagent bottles are usually stored on dedicated reagent bottle racks. Existing reagent bottle racks are mostly simple shelf-type structures or ordinary drawer-type structures.

[0003] Shelf-type storage racks are extremely inconvenient to access reagent bottles located at the back, as they are prone to knocking over bottles at the front. While ordinary drawer-type storage racks solve the access problem to some extent, if an operator accidentally pulls out multiple drawers at the same time, the center of gravity of the entire storage rack will shift forward, posing a significant risk of tipping over. This could not only damage valuable reagents but also cause serious safety accidents such as chemical leaks or even personal injury. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an anti-tipping reagent bottle storage rack.

[0005] On one hand, the present invention provides an anti-tipping reagent bottle storage rack, comprising: Frame; Multiple drawer units are pulled out and arranged at intervals on the frame; A limiting mechanism is provided on the frame to limit the pull-out state of the drawer unit; An adaptive clamping mechanism is provided on the drawer unit to adaptively adjust the clamping and placement state of the reagent bottle during the pulling process; The limiting mechanism includes a single drawer limiting component, which is configured to allow only one drawer unit to be pulled out from the front of the frame among the plurality of drawer units.

[0006] Compared with existing technologies, the beneficial effects of this invention are: by integrating a limiting mechanism and an adaptive clamping mechanism, it fundamentally solves two major pain points of traditional storage racks. On the one hand, it eliminates the risk of the storage rack tipping over due to the simultaneous pulling out of multiple drawers, greatly improving the inherent safety of the equipment; on the other hand, it achieves stable clamping of reagent bottles during storage and automatic and smooth release during retrieval, significantly improving operational convenience and efficiency.

[0007] Furthermore, the frame includes two opposing support plates and a back fixing plate fixedly connected to one side between the two support plates.

[0008] Furthermore, the single drawer limiting assembly includes a guide groove vertically formed on the support plate, a plurality of limiting blocks stacked in the guide groove, and a trigger block fixedly connected to each drawer unit; When any of the drawer units is pulled out, the trigger block on it moves with the drawer and presses against the inclined surface of the corresponding limiting block, driving the limiting block to move within the guide groove, thereby allowing the drawer unit to be pulled out smoothly; at the same time, the driven limiting block pushes all the limiting blocks above it to move upward, causing its inclined surface to disengage from the correspondence with the trigger blocks of other drawer units; while the limiting block below it is blocked by the trigger block and cannot move upward.

[0009] Furthermore, the single drawer limiting assembly also includes a reset module disposed above all the limiting blocks. The reset module includes a pressing block connected to the uppermost limiting block, a limiting post fixed to the top of the guide groove, and a reset spring sleeved on the limiting post. When the limiting block moves upward, it pushes the squeezing block upward and compresses the return spring; after the drawer unit is pushed back, under the restoring force of the return spring, the squeezing block moves downward and pushes all the limiting blocks to reset.

[0010] Furthermore, the limiting mechanism also includes a global locking component, which is used to lock all the drawer units simultaneously; The global locking assembly includes a locking sleeve disposed on the front side of the frame, a driving component disposed on the locking sleeve, and a clamping component disposed inside the locking sleeve and linked with the driving component. Specifically, by operating the driving component, the pressing component is driven to move downward and press against the uppermost limiting block, thereby restricting the upward movement of all limiting blocks.

[0011] Furthermore, the driving component includes a rotating shaft rotatably connected to the side wall of the locking sleeve, a driving wheel coaxially fixed to one end of the rotating shaft, an operating knob fixed to the other end of the rotating shaft, and an arc-shaped groove formed on the driving wheel; the pressing component includes a pressing rod slidably connected to the inner wall of the locking sleeve, and a driven pin connected to one end of the pressing rod, the driven pin being adapted to the arc-shaped groove; When the operating knob is rotated, the rotating shaft and the drive wheel rotate, causing the driven pin to move in the arc-shaped groove, which in turn drives the pressure rod to slide along the inner wall of the locking sleeve, so that its other end moves toward the uppermost limiting block and presses it.

[0012] Furthermore, the adaptive clamping mechanism includes a lateral clamping component configured to automatically release the lateral clamping of the reagent bottle during the process of the drawer unit being pulled out. The lateral clamping assembly includes: a fixed guide rod fixed to the frame, a movable clamping plate slidably disposed on the bottom plate of the drawer unit, a fixed clamping plate fixedly disposed on the bottom plate of the drawer unit, and a linkage connecting the movable clamping plate and the fixed guide rod; When the drawer unit is pulled out or pushed back, the linkage causes the movable clamping plate to move away from or closer to the fixed clamping plate.

[0013] Furthermore, an inclined guide groove is formed on the fixed guide rod, and a guide pin is fixed to the movable clamp and slidably embedded in the inclined guide groove; The inclined guide groove extends in a direction that is inclined relative to the drawer unit’s pull-out direction. When the drawer unit is pulled out, the guide pin slides along the inclined guide groove, thereby pushing the movable clamping plate to move away from the fixed clamping plate.

[0014] Furthermore, the adaptive clamping mechanism also includes a vertical release component, which is configured to synchronously control the limiting state of the upper part of the reagent bottle when the movable clamp moves; The vertical release assembly includes a lifting limit plate slidably connected to the side wall of the drawer unit, an oblique connecting rod installed on the movable clamp, a sliding through groove opened along the inclined direction of the oblique connecting rod, and a guide wheel provided on the lifting limit plate and adapted to the sliding through groove. When the movable clamping plate moves away from the fixed clamping plate, it drives the inclined connecting rod to move. Through the transmission between the sliding groove and the guide wheel, the lifting limit plate is driven to slide vertically along the side wall of the storage drawer.

[0015] Furthermore, the drawer unit includes a drawer body, a support plate mounted on the bottom of the drawer body via support legs, multiple drainage holes opened on the support plate, and a collection box that can be pulled out and disposed between the support plate and the bottom wall of the drawer body. The support plate, the bottom wall of the drawer body, and the four side walls together form a liquid collection cavity, and the liquid collection box can be pulled out from the liquid collection cavity.

[0018] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0019] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figures 1 to 2 As shown, the present invention provides an anti-tipping reagent bottle storage rack, which mainly includes a frame body 10, multiple drawer units 20, a limiting mechanism 30, and an adaptive clamping mechanism 40.

[0023] The frame 10, serving as the supporting skeleton of the entire storage rack, consists of two opposing support uprights 11 and a back fixing plate 12 fixedly connected to the rear of the two support uprights 11, resulting in a stable structure. Multiple drawer units 20 are pulled out between the two support uprights 11 via slide rails or other sliding structures and can move in the front-to-back direction. In this embodiment, the frame 10 is mounted on a support base equipped with casters. The support uprights 11 are arranged in a U-shape, and there are multiple back fixing plates 12, spaced apart on the rear of the support uprights 11, corresponding one-to-one with each drawer unit 20.

[0024] The limiting mechanism 30 is mounted on the frame 10 and is used to control the pull-out state of the drawer unit 20 to prevent multiple drawers from being pulled out simultaneously, which could cause the drawer to tip over. The adaptive clamping mechanism 40 is mounted on each drawer unit 20 and is used to automatically adjust the clamping and releasing of the reagent bottle during the drawer pulling process, making it easy to pick up and put down.

[0025] Specific implementation details of the limiting mechanism 30: The limiting mechanism 30 mainly includes a single drawer limiting component 31 and a global locking component 32.

[0026] The implementation method of the single drawer limiting component 31 is as follows: Figure 3 , Figure 4 and Figure 7 As shown. A guide groove 311 is vertically formed on the inner side wall of each of the support plates 11. Multiple limiting blocks 312 are stacked from top to bottom in the guide groove 311, and each limiting block 312 has an inclined surface 317 on the side facing the drawer unit 20.

[0027] For each drawer unit 20, a trigger block 313 is fixedly installed on both sides. When a drawer unit 20 needs to be pulled out, the trigger block 313 on that drawer unit 20 moves forward with it. During the movement, the trigger block 313 presses against the inclined surface 317 of the limiting block 312 opposite it, which is in its initial position. Under the action of the inclined surface 317, the limiting block 312 is pushed, generating a vertical displacement (e.g., retracting upward) in the guide groove 311, making way for the trigger block 313, so that the drawer unit 20 can be pulled out smoothly.

[0028] At the same time, the driven limit block 312 will push all the limit blocks 312 above it to move upwards together by a certain distance. This raises the position of the inclined surface 317 of the upper limit block 312, so that it is no longer at the same level as the trigger blocks 313 of other drawer units 20 that have not been pulled out, thus preventing other drawer units 20 from being accidentally pulled out. The limit blocks 312 below the driven limit block 312, however, cannot move upwards because they are still blocked by the trigger blocks 313 of the drawer units 20 that have been pulled out.

[0029] To ensure the single drawer limiting assembly 31 can operate cyclically, a reset module is provided above all the limiting blocks 312. This reset module includes a vertically movable pressing block 314, a limiting post 315 fixed to the top of the guide groove 311 (in this embodiment, fixed inside the locking sleeve 321), and a reset spring 316 sleeved on the limiting post 315. When the limiting blocks 312 move upwards, they push up the pressing block 314 and compress the reset spring 316. When the drawer unit 20 is pushed back, the horizontal force applied to the limiting blocks 312 disappears, and under the restoring force of the reset spring 316, the pressing block 314 moves downwards, pushing all the limiting blocks 312 back to their initial positions, completing the reset.

[0030] The implementation of the global locking component 32 is as follows Figure 5 and Figure 6 As shown. The global locking component 32 is used to lock all the drawer units 20 simultaneously; it includes a locking sleeve 321 horizontally disposed on the front side of the frame 10 (i.e., the front part between the two support uprights 11), a driving component 322 disposed on the locking sleeve 321, and a pressing component 323 disposed inside the locking sleeve 321 and linked with the driving component 322; wherein, by operating the driving component 322, the pressing component 323 is driven to move downward and press against the uppermost limiting block 312, thereby restricting the upward movement of all limiting blocks 312.

[0031] The driving component 322 includes a rotating shaft 3221 rotatably connected to the side wall of the locking sleeve 321, a driving wheel 3222 coaxially fixed to one end of the rotating shaft 3221, an operating knob 3223 fixed to the other end of the rotating shaft 3221, and an arc-shaped groove 3224 formed on the driving wheel 3222; the pressing component 323 includes a pressing rod 3231 slidably connected to the inner wall of the locking sleeve 321, and a driven pin 3232 connected to one end of the pressing rod 3231, wherein the driven pin 3232 always maintains contact with the arc.

[0032] When all drawers need to be locked, the user rotates the operating knob 3223, causing the rotating shaft 3221 and drive wheel 3222 to rotate together. During rotation, the arc-shaped groove 3224 of the drive wheel 3222 causes the driven pin 3232 to move along with it, thereby driving the entire pressure rod 3231 to slide within the locking sleeve 321 (the pressure rod 3231 to the left of the operating knob 3223 slides to the left, and the pressure rod 3231 to the right of the operating knob 3223 slides to the right), causing its end away from the operating knob 3223 to abut against the uppermost limiting block 312 (in this embodiment, it abuts against the pressing block 314). This prevents all limiting blocks 312 from moving upwards, achieving unified locking of all drawer units 20. Reversing the rotation of the operating knob 3223 causes the arc-shaped groove 3224 of the drive wheel 3222 to move along with the driven pin 3232 in the opposite direction, thus moving it away from the uppermost limiting block 312 and releasing the lock.

[0033] Specific implementation details of the adaptive clamping mechanism 40: The adaptive clamping mechanism 40 mainly includes a lateral clamping component 41 and a vertical release component 42.

[0034] The implementation of the lateral clamping assembly 41 is as follows Figures 8 to 14 As shown, a horizontally positioned guide rod 411 is fixedly installed on the frame 10, below each drawer unit 20. A movable clamping plate 412 is slidably mounted on the bottom plate of the drawer unit 20, opposite to a fixed clamping plate 413 fixedly mounted on the bottom plate, together forming a space for clamping reagent bottles. The movable clamping plate 412 includes a moving frame and multiple arc-shaped portions arranged on the moving frame, the arc surfaces of which are adapted to the sides of the reagent bottles.

[0035] The movable clamping plate 412 and the fixed guide rod 411 are connected by a linkage 414. The linkage 414 includes an inclined slide groove formed on the fixed guide rod 411, and a guide pin 4142 fixed on the movable clamping plate 412 and embedded in the inclined slide groove. The extension direction of the inclined slide groove forms an acute angle with the pull-out direction of the drawer unit 20.

[0036] When drawer unit 20 is pulled out, the entire drawer moves forward relative to the fixed guide rod 411. At this time, guide pin 4142 slides passively within the inclined slide groove. Due to the guiding effect of the inclined slide groove, as guide pin 4142 moves horizontally forward, it forces movable clamp 412 to move laterally away from fixed clamp 413, thereby widening the gap between fixed clamp 413 and movable clamp 412 and automatically releasing the lateral clamping of the reagent bottle. When drawer unit 20 is pushed back, guide pin 4142 moves in the opposite direction along the inclined slide groove, causing movable clamp 412 to move closer to fixed clamp 413 and re-clamp the reagent bottle.

[0037] The implementation of the vertical release component 42 is as follows: Figures 8 to 14 As shown, it includes a lifting limit plate 421 slidably connected to the side wall of the drawer unit 20 via a slide rail or slide groove. The lower end of an inclined connecting rod 422 is connected to the movable clamping plate 412. A sliding through groove 423 is formed along the length of the inclined connecting rod 422. A guide wheel 424 fixed to the lifting limit plate 421 is embedded in the sliding through groove 423 and can slide along it.

[0038] When the movable clamping plate 412 moves outward under the action of the lateral clamping assembly 41, it pulls the diagonal connecting rod 422 to move together. The movement of the diagonal connecting rod 422, through the cooperation of its sliding groove 423 and guide wheel 424, is converted into a downward driving force on the lifting limit plate 421, forcing the lifting limit plate 421 to slide downward along the side wall of the drawer unit 20. In this way, the upper part of the reagent bottle (especially the neck part), which was originally surrounded and restricted by the limiting hole on the lifting limit plate 421, is completely exposed, making it convenient for the operator to grasp. When the drawer is closed, the whole process is reversed, the lifting limit plate 421 rises and resets, and re-limits the reagent bottle.

[0039] Specific implementation details of drawer unit 20: like Figure 12 and Figure 15 As shown, the drawer unit 20 includes a drawer body 21. A support plate 23 is provided at the inner bottom of the drawer body 21 via two opposing support legs 22. The support plate 23 is densely covered with multiple drainage holes 24. A collection chamber is formed below the support plate 23 and at the bottom of the drawer body 21. A collection box 25 is removably placed within this collection chamber.

[0040] This design forms an effective emergency leak-proof system. If a reagent bottle placed on the support plate 23 breaks or leaks, the leaked liquid will flow through the leakage hole 24 into the collection box 25 below, without overflowing and contaminating the entire drawer or other reagent bottles. Maintenance is very convenient; simply pull out the collection box 25 periodically for cleaning.

[0041] Working principle overview In use, the operator can only pull out one designated drawer unit 20 at a time, while the limiting mechanism 30 ensures that all other drawers are locked. During the pulling out of this drawer, the adaptive clamping mechanism 40 automatically operates: the lateral clamping component 41 releases the lateral clamping force on the reagent bottle, while the vertical release component 42 descends to make room above the reagent bottle. The operator can easily and unobstructedly place and retrieve the reagent bottle. After placing the reagent bottle back and pushing the drawer back, the clamping mechanism automatically resets and re-securely clamps the reagent bottle. If it is necessary to move the entire storage rack or lock it entirely, all drawers can be locked using the global locking component 32.

[0042] In summary, the technical effects of implementing this technical solution are as follows: By integrating the limiting mechanism 30 and the adaptive clamping mechanism 40, two major pain points of traditional storage racks are fundamentally solved. On the one hand, the risk of the storage rack tipping over due to the simultaneous pulling out of multiple drawers is eliminated, greatly improving the inherent safety of the equipment. On the other hand, it achieves stable clamping of reagent bottles during storage and automatic and smooth release during retrieval, significantly improving operational convenience and efficiency.

[0043] The interlocking function of "allowing only one drawer to be opened" is cleverly achieved through the engagement mechanism between the trigger block 313 and the inclined surface 317 of the stacked limit block 312. This structure operates purely mechanically, offering high reliability and durability, requiring no external power, effectively preventing overall tipping accidents caused by misoperation, and significantly improving safety performance. The reset module design ensures that all limit blocks 312 automatically and accurately reset after the drawer is closed, preparing for the next operation and guaranteeing the stability of the mechanism's cyclic use.

[0044] By operating the drive component 322, the clamping component 323 can be pressed down, locking all limit blocks 312 at once, thereby achieving unified locking of all drawer units 20. This function is particularly important when the storage rack needs to be fixed or moved as a whole, providing an additional layer of security. It is especially suitable for environments with vibration or where non-experimental personnel may enter, enhancing the applicability and management convenience of the equipment.

[0045] The horizontal linear movement of the drawer is converted into the lateral movement of the movable clamping plate 412 by the cooperation of the inclined slide groove on the fixed guide rod 411 and the guide pin 4142. This design realizes the automated function of "pulling out the drawer and clamping it when the drawer is pushed back", without the need for additional operation. This not only effectively avoids the shaking and collision of reagent bottles during transportation or when the bottle is closed, but also completely frees up the operating space when retrieving the bottle, making the action of picking up and putting down the reagent bottle direct and smooth.

[0046] The linkage between the inclined connecting rod 422 and the lifting limit plate 421 synchronously transforms the lateral loosening action into the downward movement of the lifting limit plate 421. This design allows the neck of the reagent bottle to be fully exposed during retrieval, enabling the operator to grasp the bottle body without obstruction. This is particularly beneficial for the safe and secure handling of tall reagent bottles containing liquids, further enhancing the convenience and user-friendliness of the operation.

[0047] Through the coordinated design of the support plate 23, the leakage hole 24, and the pull-out collection box 25, a highly efficient leak-proof and waste liquid collection system is constructed. In the event of a reagent bottle breakage or leakage, the leaked liquid will be collected in the collection box 25 through the leakage hole 24, preventing contamination of other reagent bottles or drawer interiors. The pull-out collection box 25 facilitates regular cleaning and maintenance, greatly simplifying the cleaning process, ensuring a clean and safe storage environment, and meeting high laboratory management standards.
