Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment storage technology, and in particular to a colorimetric tube storage box device for storing and orderly removing colorimetric tubes. Background Technology

[0002] In chemical analysis experiments, colorimetric tubes are frequently used experimental instruments. Currently, the common methods of storing colorimetric tubes in laboratories have the following problems: Traditional drawer-style or open storage boxes require manual opening and rummaging through the tubes one by one, a process that is not only inefficient but also easily disrupts the storage order. Especially when multiple colorimetric tubes need to be retrieved consecutively, operators often have to empty all the tubes to select them, which not only increases the operation time but also easily causes collisions between tubes, leading to breakage. This risk of breakage from collisions is particularly prominent for glass colorimetric tubes. During repeated handling, colorimetric tubes easily become mixed up, making it difficult to maintain the original storage order.

[0003] Furthermore, although some sliding rail storage box designs have emerged on the market, these designs generally lack an effective single-tube release control mechanism, failing to achieve orderly and automatic retrieval of colorimetric tubes and still requiring manual intervention to complete the single-tube retrieval operation. These problems severely impact experimental efficiency and increase experimental costs. Therefore, there is an urgent need for a storage device capable of automatically sorting colorimetric tubes and controlling the retrieval of individual tubes. Utility Model Content

[0008] The bayonet mechanism is movably mounted at the connection between the front end of the track slide and the rear end of the placement groove via the reset spring. It is used to open the bayonet to release the colorimetric tube when pressed by an external force, and to automatically reset and block the next colorimetric tube under the pull of the reset spring.

[0015] The arc-shaped connecting plate is rotatably disposed in the arc-shaped limiting groove on the inner side wall of the track slide, and its front and rear ends are respectively fixedly connected to the first card block and the second card block to form a linkage arrangement.

[0016] Preferably, the first card block is provided with connecting rods at its left and right ends, and the two connecting rods extend to the outside through corresponding guide grooves and are fixedly connected to the two ends of the handle.

[0017] Preferably, the cross-sections of the first and second locking blocks are both arranged in an arc shape, and they are rotatably arranged with the corresponding arc-shaped limiting block and the arc-shaped contact surface of the sliding track, respectively.

[0018] Preferably, the top of the second locking block is provided with a lifting and dragging part with an arc-shaped cross-section for limiting and supporting the colorimetric tube; and its rear wall is provided with a groove, in which a hook is provided, and the hook is connected to the spring fixing block below through the reset spring.

[0019] Preferably, the colorimetric tube storage box device further includes a maintenance cover plate disposed on the side wall of the box structure for sealing the ends of each slot, wherein:

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] In existing technologies, colorimetric tube storage devices mostly adopt drawer-type or open structures, requiring manual searching or emptying of all tubes during retrieval, resulting in low efficiency, easy damage to tubes, and disordered order. Although some sliding rail storage devices can achieve tube sliding, they lack a controllable single-tube release mechanism, causing tubes to slide or pile up disorderly, failing to meet the need for orderly retrieval during experiments.

[0042] To address the aforementioned issues, a storage device capable of automatically sorting and releasing individual tubes is needed. Analysis reveals that the key lies in utilizing mechanical structures to achieve the orderly arrangement and controllable release of the tubes. Based on the principle of gravity sliding, a continuous channel is designed inside the box to guide the tube movement. Simultaneously, a resettable blocking mechanism is installed at key locations. When a single tube is released by external force, it automatically resets to block subsequent tubes, thus forming an orderly retrieval mechanism.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, a colorimeter tube storage box device is proposed, comprising a box structure 100, a locking mechanism 200, and a return spring 300. The upper part of the box structure 100 is provided with a placement groove 101 for sequentially placing multiple colorimeter tubes, and the lower left end is provided with a track groove 103 communicating with the placement groove 101, allowing the colorimeter tubes to slide out by gravity. The locking mechanism 200 is movably disposed at the connection between the front end of the track groove 103 and the rear end of the placement groove 101 via the return spring 300. When pressed by external force, the locking mechanism can open to release the colorimeter tube, and the return spring 300 pulls it back to automatically prevent the next colorimeter tube from being placed.

[0044] The box structure 100 refers to the main frame used to accommodate and guide the colorimetric tubes. It can be a one-piece injection-molded structure. The upper placement groove 101 and the lower track slide 103 form a continuous channel, ensuring the tubes are arranged in sequence. The track slide 103 is an inclined or arc-shaped sliding path with a smooth surface to reduce frictional resistance, allowing the tubes to slide down naturally under gravity. The locking mechanism 200 is a movable mechanical blocking component, which can be a linked locking block structure. Pressing it releases the current tube's restriction, and releasing it automatically resets to block subsequent tubes. The return spring 300 is a connecting component that provides elastic return force. It can be a tension spring, with both ends fixed to the locking mechanism 200 and the box body's fixing points, ensuring the locking mechanism returns to its original position after the external force disappears.

[0045] Specifically, the colorimetric tubes are arranged sequentially in the placement slot 101. When the first tube moves to the connection between the track slide 103 and the placement slot 101, it is blocked by the locking mechanism 200. When the handle 203 is manually pressed from the outside, it releases the restriction on the current tube, and the tube slides out along the track slide 103. After the locking mechanism 200 releases the external force, the return spring 300 pulls it back to its original position, preventing subsequent tube movement. During this process, the continuous channel design of the box structure 100 ensures automatic tube alignment, and the linkage between the locking mechanism 200 and the return spring 300 ensures that only one tube is released in a single operation.

[0046] Compared to existing technologies, traditional storage boxes rely on manual operation to separate the tubes, while this solution achieves automated single-tube release through a mechanical linkage structure. Existing sliding rail designs lack a controllable blocking mechanism, causing the tubes to slide off haphazardly. This solution, however, incorporates a resettable bayonet mechanism 200 at key connection points, combined with a reset spring 300, to achieve precise control and prevent tube accumulation or collisions.

[0047] Through the above technical solutions, this application achieves orderly storage and on-demand retrieval of colorimetric tubes, reducing efficiency losses and tube damage risks caused by manual intervention. The mechanical blocking and reset function of the bayonet mechanism 200 ensures that only one tube is released each time, avoiding tube mixing issues. The gravity sliding design of the track chute 103 simplifies the retrieval path, reduces operational complexity, and is suitable for high-frequency retrieval scenarios in laboratories.

[0048] In some of these embodiments, such as Figure 6 , Figure 7 and Figure 8 As shown, this application further proposes that the top of the box structure 100 is provided with an inlet 102 that communicates with the placement groove 101, and the cross-section of the placement groove 101 is S-shaped.

[0049] The inlet 102 refers to the opening structure located at the top 100 of the box body. Specifically, it can be implemented as a rectangular opening structure, with its axis perpendicular to the extension direction of the placement groove 101, for batch filling of colorimetric tubes. The S-shaped structure refers to the cross-section of the placement groove 101, which has a continuously curved arc profile. Specifically, it can be formed by connecting two reverse arcs to create a wave-shaped channel, guiding the colorimetric tubes to roll to the predetermined position under the action of gravity through the change of curvature.

[0050] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, this application further proposes to set the bottom of the track chute 102 as an arc-shaped sliding track 104, and to provide a blocking groove 108 for caching the colorimetric tube between the inner end of the sliding track 104 and the tail end of the placement groove 101.

[0051] The arc-shaped sliding track 104 refers to the bottom of the track chute adopting an arc-shaped curved surface structure. Specifically, it can be implemented using an arc design with a specific radius of curvature. The arc-shaped contact surface, in conjunction with the arc-shaped limiting block 105, constrains the sliding trajectory of the colorimetric tube, allowing it to move smoothly. The blocking groove 108 refers to the recessed area located between the inner end of the sliding track 103 and the tail end of the placement groove 101. Specifically, it can be implemented using a groove structure with a depth slightly larger than the diameter of the colorimetric tube, used to temporarily hold the colorimetric tube to complete the posture adjustment.

[0052] Specifically, before the locking mechanism 200 releases the colorimetric tube, the colorimetric tube first slides along the slide of the placement groove 101 into the blocking groove 108 under the action of gravity, and is supported from the bottom by the second locking block 205. During this process, its movement speed is buffered, and it is adjusted to a stable posture within the blocking groove 108. Subsequently, the locking mechanism 200 opens the locking mechanism under the action of external force, and at the same time raises the tube body at the top of the second locking block 205. The colorimetric tube slides out of the locking mechanism under the action of gravity and continues to slide down along the arc-shaped sliding track 104. The arc-shaped track 104 reduces sliding friction through curved surface contact, ensuring smooth sliding out.

[0053] In some of these embodiments, such as Figure 6 , Figure 7 and Figure 8 As shown, this application further proposes that an arc-shaped limiting block 105 and an arc-shaped limiting groove 106 for limiting the installation bayonet mechanism 200 are provided on the inner sidewall of the middle and one end of the track slide 103, and guide slides 107 are respectively provided on the left and right ends of its top.

[0054] The arc-shaped limiting block 105 refers to a block with one end fixed to the inner wall of the track chute and the other end horizontally arranged. Its outer wall is configured as an arc-shaped curved surface that can rotate in conjunction with the arc surface of the inner wall of the first locking block 201 on the locking mechanism 200. Specifically, it can be implemented using an arc-shaped metal or plastic block with the same curvature as the contact surface of the first locking block 201. This is used to limit the lateral displacement of the locking mechanism 200 and provide a rotation fulcrum. The arc-shaped limiting groove 106 refers to an arc-shaped groove formed on the inner wall of the track chute 103. Specifically, it can be implemented using an arc-shaped channel matching the outer contour of the arc-shaped connecting plate 204. This is used to constrain the rotation angle range of the arc-shaped connecting plate 204. The guide chute 107 refers to a straight channel set at the top of the track chute 103. Specifically, it can be implemented using a through-groove structure. This is used to guide the connecting rod 202 to move linearly along a fixed direction.

[0055] Specifically, the first locking block 201 and the second locking block 205 of the locking mechanism 200 are rotatably connected to the arc-shaped limiting groove 106 via the arc-shaped connecting plate 204. The arc-shaped limiting block 105 and the arc-shaped contact surface of the first locking block 201 cooperate to form a rotation fulcrum, allowing the locking mechanism 200 to rotate around this fulcrum during the pressing operation. The arc-shaped trajectory of the arc-shaped limiting groove 106 limits the rotation amplitude of the arc-shaped connecting plate 204, preventing excessive rotation that could lead to locking misalignment.

[0056] Simultaneously, the connecting rods 202 at both ends of the handle 203 are embedded in the guide grooves 107. When an external force is applied to the handle 203, the connecting rods 202 slide upward or downward along the straight path of the guide grooves 107, causing the first locking block 201 and the second locking block 205 to open and close synchronously relative to the upper end of the track 104, thereby opening or closing the bayonet. Through the synergistic effect of the arc-shaped limiting block 105 and the arc-shaped limiting groove 106, the movement trajectory of the bayonet mechanism 200 is strictly limited within a predetermined range, preventing offset or jamming caused by installation gaps or uneven force.

[0057] In addition, such as Figure 8 and Figure 9 As shown, in order to solve the problem of bayonet closure failure caused by unstable installation of the reset spring 300, a spring fixing block 109 is provided at the bottom of the blocking groove 108. The spring fixing block 109 refers to the strip structure fixed at the bottom of the blocking groove 108, which is used to provide a stable fixing point for the lower end of the reset spring 300 and prevent the spring from displacing during repeated extension and contraction.

[0058] Meanwhile, a storage slot 110 is provided on the right side of the blocking slot 108, corresponding to the lower right end of the box structure 100. The storage slot 110 refers to the cavity area located at the lower right end of the box structure with an open side wall. Specifically, it can be implemented using a slot structure parallel to the blocking slot 108, which is used to expand the storage space and realize multi-functional storage by utilizing the unused area at the bottom of the device.

[0059] In some of these embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, to enable the bayonet mechanism 200 to stably control the release of a single tube, the structural design of the bayonet mechanism 200 is optimized to achieve precise blocking and automatic reset of the colorimetric tube. The bayonet mechanism 200 includes a first locking block 201, an arc-shaped connecting plate 204, and a second locking block 205.

[0060] Specifically, the first locking block 201 is movably disposed within the groove on the upper left of the arc-shaped limiting block 105, and is arranged parallel to the second locking block 205 movably disposed on the top of the blocking groove 108, forming an openable locking slot with the inner end of the sliding track 104. The parallel arrangement of the first locking block 201 and the second locking block 205 allows them to move synchronously within the groove, thereby precisely controlling the opening and closing gap of the locking slot. The design of the first locking block 201 located in the groove on the upper left of the arc-shaped limiting block 105 can constrain its movement trajectory and prevent deviation; the layout of the second locking block 205 located on the top of the blocking groove 108 allows it to directly act on the sliding path of the colorimetric tube.

[0061] The arc-shaped connecting plate 204 is rotatably disposed within the arc-shaped limiting groove 106 on the inner side wall of the track slide 103, and its front and rear ends are respectively fixedly connected to the first locking block 201 and the second locking block 205, forming a linkage arrangement. The first locking block 201 and the second locking block 205 are rigidly linked through the arc-shaped connecting plate 204. When an external force is applied to the first locking block 201, the rotation of the arc-shaped connecting plate 204 within the arc-shaped limiting groove 106 can synchronously drive the displacement of the second locking block 205, ensuring the synchronicity and stability of the locking action.

[0062] Specifically, when an external force is applied to the first locking block 201 via the handle 203, the first locking block 201 moves downward along the slide groove, and the arc-shaped connecting plate 204 drives the second locking block 205 to rotate synchronously outward of the blocking groove 108. At this time, the gap between the first locking block 201 and the inner end of the sliding track 104 increases, forming a release channel. The second locking block 205 disengages from the colorimetric tube on the sliding track 104, and the open end of the colorimetric tube slides out along the sliding track 104, realizing single-tube material handling. When the external force is removed, the return spring 300 pulls the second locking block 205 to return to its original position, and the arc-shaped connecting plate 204 rotates in the opposite direction within the arc-shaped limiting groove 105, driving the first locking block 201 to move upward synchronously to return to its initial position. The guiding effect of the arc-shaped limiting groove 105 keeps the rotation trajectory of the arc-shaped connecting plate 204 stable, eliminating the reset deviation caused by mechanical clearance. The parallel arrangement of the two locking blocks ensures that the gap change is consistent during the opening and closing of the locking slot, ensuring that only one colorimetric tube is allowed to pass through at a time.

[0063] Through the above technical solution, this application solves the problem of unstable single-tube release caused by poor linkage of the bayonet mechanism 200. The two bayonet blocks form a rigid linkage through the arc-shaped connecting plate 204, ensuring the synchronicity and consistency of the bayonet opening and closing actions. The rotational guide design of the arc-shaped limiting groove 105 enables automatic position calibration during the reset process, avoiding the jamming phenomenon caused by mechanical clearance in traditional structures. This linkage mechanism achieves precise single-tube release while ensuring reset accuracy through mechanical constraints, making the colorimetric tube handling process stable and controllable.

[0064] In some of these embodiments, such as Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, to solve the problems of uneven force application leading to jamming of the locking block when operating the locking mechanism 200 with one hand, and unstable linkage between the external operating components and the internal locking block, connecting rods 202 are respectively provided at the left and right ends of the first locking block 201. The two connecting rods 202 extend to the outside through corresponding guide grooves 107 and are fixedly connected to the two ends of the handle 203, so that a two-point linkage structure is formed by the symmetrically arranged connecting rods 202 and the guide grooves. The guide grooves 107 constrain the movement trajectory of the connecting rods 202, so that when the handle 203 is subjected to external force, it can synchronously drive the two ends of the first locking block 201 to achieve balanced displacement.

[0065] Specifically, the connecting rod 202 extends through the guide groove 107 on the side wall of the box and is fixed to the handle 203. This ensures the effective transmission of external operating force while limiting the degree of freedom of movement of the connecting rod 202 through the groove structure, preventing the locking block from deflecting due to unilateral force. The handle 203 is fixed at both ends to the connecting rods 202 on both sides, forming a symmetrical force application structure, further improving the stability of the opening and closing action of the locking mechanism 202. This design, through an internally and externally linked mechanical structure, effectively solves the technical defect of easy jamming in traditional single-point force application mechanisms while enabling single-handed pressing operation.

[0066] In some of these embodiments, such as Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, to further ensure the smoothness and durability of the opening and closing of the locking mechanism 200, the inner and outer walls of the cross-sections of the first locking block 201 and the second locking block 205 are both designed with an arc-shaped structure. These are rotatably arranged with the corresponding arc-shaped limiting block 105 and the arc-shaped contact surface of the sliding track 104, forming a rotational fit. The fit of the arc-shaped contact surfaces allows the locking blocks to rotate smoothly along a predetermined trajectory when subjected to force, ensuring both the smoothness of the opening and closing action of the locking mechanism 200 and distributing the force through surface contact, thus improving structural stability.

[0067] In addition, such as Figure 9 and Figure 10 As shown, to prevent the colorimetric tube from breaking due to friction or impact during its sliding out, a curved lifting and dragging part 206 is provided at the top of the second locking block 205 to limit and support the colorimetric tube. Through the cooperation of the curved lifting and dragging part 206 and the return spring 300 linkage structure, buffering protection is achieved during the sliding out process of the colorimetric tube, and the locking mechanism automatically resets. Specifically, the curved lifting and dragging part 206 at the top of the second locking block 205 adopts a curved surface design that matches the outer wall of the colorimetric tube, forming surface contact when limiting and supporting the colorimetric tube, which can disperse the tube pressure and reduce sliding friction.

[0068] Meanwhile, to ensure that the locking mechanism 200 can automatically reset and block the next tube after releasing the colorimetric tube, a groove 207 is provided on the rear wall of the second locking block 205, and a hook 208 is provided in the groove 207. The hook 208 is connected to the spring fixing block 109 below through a reset spring 300. The reset spring 300 provides automatic rebound force after the locking mechanism 200 is pressed, and also absorbs the impact energy when the colorimetric tube falls through spring deformation.

[0069] Specifically, when the colorimetric tube slides into the blocking groove 108 and lands on top of the second locking block 205, the arc-shaped contour of the lifting and dragging part 206 guides the tube body to transition smoothly. At the same time, the elastic buffering effect of the return spring 300 prevents the tube body from rigidly colliding with the locking block. This dual protection mechanism effectively reduces the risk of colorimetric tube breakage. The fixed connection between the hook 208 and the spring fixing block 109 ensures that the return spring 300 is always in a pre-tensioned state, allowing the second locking block 205 to quickly return to the blocking position after releasing the tube body.

[0070] In some of these embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, in order to facilitate the inspection and maintenance of the storage box device, an inspection cover plate 400 is installed on the side wall of each slot of the box structure 100 with an open end. The inspection cover plate 400 is used to seal the slot ends on the side wall of the box structure 100 to prevent the colorimetric tube from accidentally sliding out or foreign objects from entering through a physical barrier, thus ensuring the airtightness of the storage box.

[0071] Specifically, an observation window 401 is provided on the inspection cover plate 400 at the position corresponding to the placement groove 101 and the track slide 103. The observation window 401 is a strip-shaped or circular transparent observation window structure. The opening of the observation window 401 allows the operator to observe the arrangement and flow of the colorimetric tubes in the placement groove 101 and the track slide 103 in real time without opening the inspection cover plate 400. This avoids the wear and tear on the parts caused by frequent disassembly and improves the convenience of use.

[0072] In addition, to improve the installation stability and quick disassembly of the inspection cover 400 on the side wall of the housing structure 100, several pins 402 corresponding to several pin holes 111 on the side wall of the housing structure 100 are provided on the inner side wall of the inspection cover 400. The corresponding arrangement of the pins 402 and the pin holes 111 adopts a detachable connection method, which not only ensures the stability of the installation of the inspection cover 400, but also allows for quick separation of the inspection cover 400 from the housing structure 100 during maintenance, enabling targeted local maintenance without affecting the overall structure.

[0073] Combination Figures 1 to 10As shown, the working principle of this colorimetric tube storage box device is as follows: The placement groove 101 inside the box structure 100 is S-shaped and can hold 8 colorimetric tubes. When loading, the colorimetric tubes slide into the placement groove 101 through the inlet 102 and are arranged tightly to the front end of the track slide 103 under the action of gravity. When retrieving the tube, pressing the handle 203 drives the connecting rod 202 to move downward, simultaneously causing the first locking block 201 to rotate around the arc-shaped limiting block 105; the arc-shaped connecting plate 204 moves upward in conjunction with the second locking block 205, opening the locking slot; the foremost colorimetric tube slides out from the opened locking slot at the top of the sliding track 104, while the rising second locking block 205 blocks the tube from moving forward to fill the gap; releasing the handle 203 causes the reset spring 300 to pull the hook 208, the second locking block 205 moves downward to reset, and at the same time, the tube at the tail end of the placement slot 101 moves forward to fill the gap, re-entering the blocking slot 108, and the upper end of the sliding track 104, in conjunction with the lifting part 206, blocks the next colorimetric tube.
