Description

Technical Field

[0001] The invention relates to the technical field of laboratory equipment, and in particular to a chemical reagent tube placement rack. Background Art

[0002] In the daily operation of chemical laboratories, reagent tubes are key containers for carrying chemical reagents. Their storage and management are directly related to the safety and efficiency of the experiment. However, the traditional storage methods of reagent tubes often have many shortcomings, such as poor stability, easy collision and breakage, inconvenient access, and poor heat dissipation and ventilation. These problems not only increase the risks in the experimental process, but also reduce the efficiency and quality of experimental work.

[0003] First, traditional reagent tube storage racks often use a simple frame structure that lacks sufficient stability and closure, making the reagent tubes vulnerable to interference from external factors during storage, causing accidental collisions or even ruptures. In addition, due to the lack of effective protection measures, the safety of the reagent tubes cannot be fully guaranteed.

[0004] Secondly, in terms of clamping and fixing the reagent tube, the traditional method often relies on manual operation, which is not only inefficient, but also difficult to ensure the tightness and stability of the clamping. When moving or carrying the reagent tube, a slight carelessness may cause a collision or fall off, resulting in waste of reagents or even safety accidents.

[0005] Furthermore, the rapid location and isolation of reagent tubes is also a major problem in laboratory management. Traditional storage methods often cannot provide convenient reagent tube location and isolation functions, which requires laboratory personnel to spend a lot of time searching and sorting when taking reagents, reducing work efficiency.

[0006] In addition, during the long-term sealed storage of reagent tubes, the lack of heat dissipation and ventilation measures at the bottom can easily lead to temperature accumulation, affecting the stability and safety of the reagents. This problem is particularly prominent when conducting high-temperature or exothermic reactions. Summary of the invention

[0007] The present invention relates to a chemical reagent tube placement rack, which utilizes the gravity principle and the design of the mechanical structure to realize the automatic, tight and safe clamping of the reagent tube. When the placement rack is lifted, the sinking base automatically moves down under the action of gravity, and the clamping block is driven to tightly clamp the reagent tube through the ingenious cooperation of the connecting rod and the guide hole. This design not only simplifies the operation process and improves the clamping efficiency, but also ensures the uniformity and stability of the clamping force. At the same time, when the placement rack is stably placed, the clamping block can be automatically loosened, which is convenient for free use of the reagent tube, greatly improving the convenience of operation.

[0008] The present invention provides a chemical reagent tube placement rack, specifically including: a test tube rack guard plate, end side plates, a top sealing plate, a fixed bottom plate, a sunken base, a front guard plate, a rear guard plate, a sliding baffle, reagent tubes, clamping blocks, and fixed buckle plates; there are two test tube rack guard plates, which are distributed parallel to each other front and rear.

The lower end of the fixed buckle plate is fixedly connected to the fixed bottom plate, and the upper end of the fixed buckle plate is fixedly connected to the top sealing plate. And the part of the fixed buckle plate connected to the test tube rack guard plate is also in a fixed connection state; between the other ends of the front guard plate and the rear guard plate, a "C"-shaped sliding baffle is vertically slidably clamped, and the sliding baffle slides between the fixed bottom plate and the top sealing plate; A sunken base is provided below the fixed bottom plate. On the top plane of the sunken base, two sinking partition plates are vertically provided upward in a group at uniform intervals. The sinking partition plates vertically penetrate through the fixed bottom plate to between the clamping cavities of the two test tube rack guard plates; at a position near the upper end between each group of sinking partition plates, clamping blocks are symmetrically provided front and rear. The side walls of the two opposite clamping blocks are concave surfaces for clamping the reagent tubes to be placed, and the reagent tubes are vertically clamped between the clamping blocks of the same group.

[0009] Optionally, vertical convex clamping strips are provided on the outer walls of the ends of the test tube rack guard plate, the front guard plate, and the rear guard plate opposite to the sliding baffle. The two ends of the sliding baffle are vertically slidably clamped with the corresponding convex clamping strips on the test tube rack guard plate, the front guard plate, and the rear guard plate.

[0010] Optionally, U-shaped handle bars are respectively provided on the two side walls at the left and right ends of the top sealing plate. A magnet is embedded at one end of the top sealing plate opposite to the sliding baffle. A magnet with a different magnetic property from the magnet is embedded at the upper end of the sliding baffle. Anti-slip strips are evenly arranged on the outer side wall of the sliding baffle. The sliding baffle is adsorbed and fixed by the magnet after being pushed up. Placement openings are provided on the top sealing plate at the positions corresponding to the placement positions of the reagent tubes.

[0011] Optionally, a support groove is provided on the fixed bottom plate at the position corresponding to the lower end of the placed reagent tube. The support groove is a conical groove structure, and the middle of the support groove is a downward through-hole structure. A buffer pad is laid on the groove wall of the support groove.

[0012] Optionally, "V"-shaped guiding holes are symmetrically opened on the left and right of the sinking partition plates; Suction cups are respectively provided at the four corners of the bottom plane of the sunken base.

[0013] Optionally, a viewing window is inlaid on the front guard plate at the position corresponding to the reagent tube.

[0014] Optionally, vertical heat dissipation holes evenly spaced left and right are provided on the rear guard plate at positions corresponding to the reagent tubes.

[0015] Optionally, the upper and lower ends of the front guard plate and the rear guard plate are provided with outwardly protruding convex rails, and the front guard plate and the rear guard plate are horizontally slid through the convex rails and placed between the rail groove at the lower end of the test tube rack guard plate and the rail groove at the top edge of the fixed bottom plate, and the front guard plate and the rear guard plate can be slid out to one side of the sliding baffle.

[0016] Optionally, a hanging groove running through front and back is horizontally opened on the inner side wall of the end side plate at a position corresponding to the position of the clamping block.

[0017] Optionally, the clamping blocks on the same side are fixed in series via a connecting rod, the connecting rod also passes through the guide hole on the corresponding side, and two ends of the connecting rod are respectively fixed with directional blocks, which are slidably placed in the hanging groove on the corresponding side; When the test tube placement rack is lifted, the sinking base part moves downward under the action of its own gravity, and the sinking partition moves downward and squeezes the two connecting rods to move inward through the guide hole, and the two opposite clamping blocks clamp the reagent tube; When the test tube rack is placed on the workbench, the sinking base fits with the fixed bottom plate, the overall center of gravity moves downward, the sinking partition moves upward and squeezes the two connecting rods through the guide holes to move outward in the opposite direction, the two opposite clamping blocks do not contact the reagent tube, and the reagent tube can be taken out freely.

[0018] The present invention provides a chemical reagent tube placement rack, which has the following beneficial effects: First, by fastening the test tube rack guard plate, end side plates, top sealing plate, fixed bottom plate and sinking base, a stable and closed main frame is constructed, providing a safe and reliable storage environment for the reagent tubes. This design not only effectively prevents accidental collisions of the reagent tubes during storage, but also further improves the stability of the structure and ensures the safety of the reagent tubes by strengthening the front and rear guard plates.

[0019] Secondly, the adaptive clamping system composed of the sinking base and the sinking partition and clamping block on it shows a high degree of intelligence and humanization. When the placement rack is lifted, the sinking base automatically moves down due to gravity, and the clamping block tightly clamps the reagent tube through the cooperation of the connecting rod and the guide hole, effectively preventing the risk of collision and breakage during movement. When the placement rack is placed stably, the clamping block automatically loosens, facilitating the free use of the reagent tube, greatly improving the convenience of operation.

[0020] In addition, the design of the sliding baffle provides great convenience for the rapid positioning and isolation of the reagent tubes. The vertical sliding structure between the sliding baffle and the front and rear guard plates, combined with the interaction between the magnet and the magnetic block, enables the sliding baffle to be firmly positioned and easily unlocked. This design not only simplifies the placement and removal process of the reagent tubes, but also provides an additional protective barrier or a convenient cleaning and maintenance channel for the reagent tubes by switching the sliding baffle in different positions.

[0021] In terms of detail processing, the bracket design on the fixed bottom plate provides an accurate positioning point for the reagent tube, ensuring the stability and neatness of the reagent tube during storage. At the same time, the conical groove structure and through-hole design of the bracket also ensure the heat dissipation and ventilation effect at the bottom of the reagent tube, avoiding the problem of temperature accumulation caused by long-term closed storage. In addition, the suction cup design at the bottom of the sinking base not only enhances the stability of the placement frame on the workbench, but also ensures that the sinking base can move down smoothly when the device is lifted, thereby triggering the automatic clamping function of the clamping system.

Two evenly spaced sinking partitions 501 are vertically provided on the top plane of the sinking base 5 in a group. The sinking partitions 501 vertically pass through the fixed bottom plate 4 to the clamping cavity between the two test tube rack guard plates 1. Clamping blocks 10 are symmetrically provided front and back near the upper end between each group of sinking partitions 501. The side walls of the two opposite clamping blocks 10 are concave surfaces, which are used to clamp the reagent tubes 9 to be placed. The reagent tubes 9 are vertically clamped between the clamping blocks 10 of the same group. The main structure of the placement rack is composed of test tube rack guard plates 1, end side plates 2, top sealing plates 3, fixed bottom plates 4, sinking bases 5 and other components. These components are fastened to form a stable frame. The test tube rack guard plates 1 serve as protective barriers on both sides, and together with the end side plates 2, top sealing plates 3 and fixed bottom plates 4, define the placement space for the reagent tubes. The front guard plates 6 and the rear guard plates 7 further enhance the stability of the structure and provide additional protection.

[0028] Among them, the outer walls of the test tube rack guard plate 1, the front guard plate 6 and the rear guard plate 7 at the end opposite to the sliding baffle plate 8 are all provided with a vertical convex card strip, and the two ends of the sliding baffle plate 8 are respectively slidably connected with the corresponding convex card strips on the test tube rack guard plate 1, the front guard plate 6 and the rear guard plate 7.

Anti-slip strips 801 are evenly spaced on the outer wall of the baffle 8. After the sliding baffle 8 is pushed up, it is adsorbed and fixed by the magnetic block 302. When the sliding baffle 8 is at the bottom, the front guard plate 6 and the rear guard plate 7 are in a locked state. The front guard plate 6 and the rear guard plate 7 can provide improved structural strength and provide a structural barrier to prevent the reagent tube 9 from accidentally exploding and rupturing and injuring people. When the sliding baffle 8 moves up, the front guard plate 6 and the rear guard plate 7 can be pulled out for cleaning and maintenance to ensure the clarity of the window 601 and the heat dissipation effect of the heat dissipation hole 701. A placement opening 301 is provided on the top sealing plate 3 at a location corresponding to the placement of the reagent tube 9 .

[0029] Among them, a bracket 401 is provided at the lower end position of the reagent tube 9 placed on the fixed base plate 4. The bracket 401 is a conical groove structure, and the middle part of the bracket 401 is a downward through hole structure. A buffer pad is laid on the groove wall of the bracket 401, which can make the reagent tube 9 accurately positioned, and the downward through hole structure of the bracket 401 can ensure the heat dissipation and ventilation effect of the bottom of the reagent tube 9.

[0030] Among them, the sinking partition 501 is symmetrically provided with guide holes 5011 in the shape of an "eight"; Suction cups 502 are respectively provided at the four corners of the bottom plane of the sinking base 5 .

[0031] Among them, a window 601 is embedded in the position of the front guard plate 6 corresponding to the position of the reagent tube 9, so as to facilitate the observation of the test reaction phenomenon.

[0032] Among them, vertical heat dissipation holes 701 evenly spaced left and right are opened on the rear guard plate 7 at the position corresponding to the reagent tube 9 to improve the heat dissipation effect.

[0033] Among them, the upper and lower ends of the front guard plate 6 and the rear guard plate 7 are provided with outwardly protruding convex rails. The front guard plate 6 and the rear guard plate 7 are placed between the rail groove at the lower end of the test tube rack guard plate 1 and the rail groove at the top edge of the fixed bottom plate 4 through the convex rails. The front guard plate 6 and the rear guard plate 7 can be slid out to the side of the sliding baffle 8.

[0034] A hanging groove 201 extending from front to back is horizontally opened on the inner wall of the end side plate 2 at a position corresponding to the position of the clamping block 10 .

[0035] Embodiment 2, on the basis of embodiment 1, the clamping blocks 10 on the same side are fixedly connected in series through a connecting rod 1001, the connecting rod 1001 also passes through the guide hole 5011 on the corresponding side, and the two ends of the connecting rod 1001 are respectively fixed with an orientation block 1002, and the orientation block 1002 is slidably placed in the hanging groove 201 on the corresponding side; When the test tube placement rack is lifted, the sinking base 5 moves downward under its own gravity, and the sinking partition 501 moves downward and squeezes the two connecting rods 1001 to move inward through the guide hole 5011, and the two opposite clamping blocks 10 clamp the reagent tube 9; When the test tube rack is placed on the workbench, the sinking base 5 fits with the fixed bottom plate 4, the overall center of gravity moves downward, the sinking partition 501 moves upward and squeezes the two connecting rods 1001 through the guide hole 5011 to move outward in the opposite direction, and the two opposite clamping blocks 10 are not in contact with the reagent tube 9, so the reagent tube 9 can be taken out freely. Therefore, when the test tube rack is lifted and carried for transfer, the reagent tube 9 can be automatically clamped to prevent the reagent tube 9 from colliding and breaking. At the same time, when placed on the workbench, it can restore to a free state, which is convenient for use, and the downward movement of the center of gravity makes it more stable.

[0036] The working principle of this embodiment: First, the main frame of the placement rack is constructed by fastening components such as the test tube rack guard plate 1, the end side plate 2, the top sealing plate 3, the fixed bottom plate 4 and the sinking base 5, forming a stable and closed space for protecting and placing the reagent tube 9. The test tube rack guard plate 1 serves as a barrier on both sides, and together with the end side plate 2, the top sealing plate 3 and the fixed bottom plate 4, defines the storage area of ​​the reagent tube. The front guard plate 6 and the rear guard plate 7 not only enhance the stability of the structure, but also provide observation and heat dissipation functions through the window 601 and the heat dissipation hole 701 thereon.

[0037] In terms of the clamping and fixing of the reagent tube, the sinking base 5 and the sinking partition 501 and the clamping block 10 thereon play a key role. The sinking partition 501 passes through the fixed bottom plate 4 to provide support for the clamping block 10. The concave side wall design of the clamping block 10 enables it to tightly clamp the reagent tube 9, ensuring its stability during storage. More uniquely, the clamping block 10 is connected to the guide hole 5011 on the sinking partition 501 through the connecting rod 1001, forming an adaptive clamping system. When the placement rack is lifted, the sinking base 5 moves downward due to gravity, and the connecting rod 1001 is squeezed through the guiding hole 5011, so that the clamping block 10 automatically clamps the reagent tube inward to prevent it from colliding and breaking during movement. When the placement rack is stably placed on the workbench, the sinking base 5 fits with the fixed bottom plate 4, and the clamping block 10 is loosened under the reverse action of the connecting rod 1001, which is convenient for free access to the reagent tube.

[0038] In addition, the design of the sliding baffle 8 facilitates the rapid positioning and isolation of the reagent tubes. The sliding baffle 8 can slide vertically between the front guard plate 6 and the rear guard plate 7. The magnet embedded in the upper end interacts with the magnetic block 302 on the top sealing plate 3 to achieve a stable positioning of the sliding baffle 8. When the sliding baffle 8 is in the lower position, the front guard plate 6 and the rear guard plate 7 are locked, providing an additional protective barrier for the reagent tubes. When cleaning and maintenance or observing the reagent reaction is required, the sliding baffle 8 only needs to be moved up, and the front guard plate 6 and the rear guard plate 7 can be easily pulled out for subsequent operations.

[0039] In terms of detail processing, the bracket 401 on the fixed bottom plate 4 provides an accurate positioning point for the reagent tube and ensures the heat dissipation and ventilation effect at the bottom. At the same time, the suction cup 502 design at the bottom of the sinking base 5 enhances the stability of the placement frame on the workbench, prevents it from sliding or tipping during operation, and ensures that the sinking base 5 can move down smoothly when the device is lifted.

[0040] In this article, there are a few points to note: 1. The drawings of the embodiments of the present invention only involve structures related to the embodiments of the present invention, and other structures can refer to the general design.

[0041] 2. In the absence of conflict, the embodiments of the present invention and the features therein may be combined with each other to obtain new embodiments.

[0042] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
