Description

Technical Field

[0002] In vitro diagnostic reagents play an important role in modern medicine. Their accuracy and reliability directly affect the diagnosis and treatment of diseases. Therefore, it is very important to ensure the quality and stability of in vitro diagnostic reagents during storage and transportation. Storage and protection boxes, as the main equipment for storing and transporting in vitro diagnostic reagents, play an irreplaceable role.

[0004] Currently, multiple different types of reagent tubes can be stored in the box at the same time by replacing specific mounting plates. However, this solution has significant limitations. Since the opening size of the mounting slot is fixed, the entire mounting plate must be replaced frequently whenever reagent tubes of different specifications or types need to be stored. This not only increases the complexity of the operation, but also leads to a series of problems in practical applications. Specifically, in order to meet the storage needs of different reagent tubes, laboratories often need to prepare multiple sets of mounting plates of different specifications as backup. However, in actual application, most of these spare mounting plates are often idle, resulting in a waste of resources and occupation of storage space. In addition, frequent replacement of mounting plates also increases time costs and reduces work efficiency. Summary of the invention

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] For example, see Figure 2 and Figure 3 It can be seen that two storage modules are symmetrically arranged inside the box 1, and the storage modules are mainly used to store reagent tubes. A storage cavity 1001 is reserved between the two storage modules, and the storage cavity 1001 can store some commonly used tools. Figure 1 As shown, the top of the box body 1 can be fixed with a box cover 2 through the box buckles on both sides. The box cover 2 covers the top opening of the box body 1 to effectively protect the reagent tubes placed inside the box body 1. In addition, the number of boxes 1 is not limited to one. The lock buckle can be used to connect multiple boxes 1 up and down, thereby providing more storage modules. A card slot is correspondingly provided on the side of each box body 1. The operator can put the corresponding card into it to facilitate knowing the type and purpose of the reagent tube installed in the box body 1.

[0024] For the storage module, a universal clamping plate 3 including the core components of the storage module is provided. Figure 2 and Figure 5 It can be seen that the surface of the universal clamping plate 3 is provided with a plurality of equally spaced placement grooves 300, and the surface shape of the placement grooves 300 is a combination of a rectangle and a triangle. The placement grooves 300 can be used to limit the position of the reagent tubes so that they can be placed in order in the box 1 to avoid the problem of reagent tube accumulation. In addition, the side of the universal clamping plate 3 is provided with a guide limit block fastened by bolts. Correspondingly, from Figure 2 and Figure 3 It can be seen that a dovetail guide frame is fixedly installed on the inner wall of the box body 1, and the guide limit block and the dovetail guide frame work together to ensure that the universal clamping plate 3 can only perform a one-way up and down reciprocating motion when placed in the storage module. Figure 6 and Fig.12 It can be seen that the inner side of the universal clamping plate 3 is provided with an adjusting push rod slide 7 which is installed movably by means of a dovetail groove guide, and the adjusting push rod slide 7 can only move along the inner side of the universal clamping plate 3. The surface of the adjusting push rod slide 7 is provided with a distance adjustment frame 14 which is fastened by bolts. Figure 6 It can be seen that the distance-adjusting frame 14 is constructed by a horizontal rod and a plurality of vertical rods, and the end of one vertical rod is fastened to the adjusting top rod slide 7 by bolts, so that the adjusting top rod slide 7 can drive the distance-adjusting frame 14 to move horizontally. When the distance-adjusting frame 14 moves to the right, the vertical rod in the distance-adjusting frame 14 is relatively close to the triangle of the placement slot 300, and the inner angle of the triangle and the limitation of the distance-adjusting frame 14 are used to limit the size of the slot that can be actually used in the placement slot 300, so as to store medicine bottles of different diameters.

[0025] The inner wall of the box body 1 is provided with a wedge-shaped guide frame 6 which is fastened to one side of the adjusting top rod slide 7 by bolts. Fig.10 and Fig.11 It can be seen that the side of the wedge-shaped guide frame 6 is a smooth inclined surface. When the universal clamping plate 3 moves vertically downward using the dovetail-shaped guide frame, the adjusting push rod slide 7 moves synchronously downward along the side inclined surface of the wedge-shaped guide frame 6. Fig.11 It can be seen that the adjusting push rod slide 7 following the universal clamping plate 3 downward is blocked by the wedge-shaped guide frame 6 and has a tendency to be retracted into the universal clamping plate 3. Fig.12It can be clearly seen that when the push rod slide 7 is adjusted to drive the distance adjustment frame 14 to move to the right, the vertical rod of the distance adjustment frame 14 can be moved to the right, thereby changing the size of the actual work of the placement slot 300. It can be seen from this that the present embodiment 1 can change the size of the notch of the actual work of the placement slot 300 by changing the actual descending height of the universal clamping plate 3. By adjusting the actual height of the installation of the universal clamping plate 3 in each storage module, it is possible to store reagent tubes of different outer diameters. In addition, the universal clamping plate 3 mentioned in the present embodiment 1 has versatility, and any universal clamping plate 3 can be installed and used in the storage box, thereby avoiding the problem of being idle due to the inappropriate notch of the placement slot 300.

[0026] After the universal clamping plate 3 is adjusted, the slot of the corresponding placement slot 300 that can be actually used is relatively determined. In order to always maintain the size of the slot after adjustment, it is necessary to ensure that the universal clamping plate 3 always maintains the required position. Figure 6 It can be seen that inside the universal clamping plate 3 and relatively far from the side of the adjusting push rod slide 7, there is a gear row slide 9 movably installed by using a dovetail groove, and a push spring 12 is arranged between the gear row slide 9 and the adjusting push rod slide 7. The push spring 12 pushes the adjusting push rod slide 7 and the gear row slide 9 to be relatively far away from each other. On the one hand, the adjusting push rod slide 7 extends outward from the side of the universal clamping plate 3, and on the other hand, the limiting push rod 8 threadedly fixed on the side of the gear row slide 9 extends from the other side of the universal clamping plate 3. Figure 2 , Figure 4 , Fig.10 and Fig.11 It can be seen that an adjustment rod 4 is movably installed in the middle of the inner side of the box body 1 and between the two storage modules. An adjustment hand wheel 401 is arranged on the top of the adjustment rod 4. The operator can drive the adjustment rod 4 to rotate by using the adjustment hand wheel 401. Figure 4 It can be seen that a plurality of equally spaced ring frames are fixedly mounted on the side of the adjusting rod 4. When the limiting push rod 8 is inserted between the two ring frames, its up and down movement can be restricted. On this basis, in order to facilitate the installation and removal of the universal clamping plate 3, combined with Figure 4 It can be seen that a distance-increasing arc block 400 is fixedly installed on the side of the adjustment rod 4, and the outer side of the distance-increasing arc block 400 is arc-shaped. In addition, a reset groove 402 is provided in the middle of the outer side of the distance-increasing arc block 400. The reset groove 402 is a vertical rectangular groove. When the limiting push rod 8 is inserted into the reset groove 402, there will be no obstruction when the limiting push rod 8 moves up and down. A mounting groove 403 is provided on the side of the adjustment rod 4 and on the ring frame. Two mutually symmetrical mounting grooves 403 are arranged on a ring frame. There is a step surface between the mounting groove 403 and the side wall of the adjustment rod 4. When the limiting push rod 8 moves downward and passes through the mounting groove 403, it needs to overcome the movement resistance brought by the step surface. In addition, Fig.12It can be seen that under normal conditions, the two limit push rods 8 respectively reach the arc ends of the distance increasing arc block 400, and there is a certain distance between the installation slot 403 and the arc ends of the distance increasing arc block 400, which ensures that the limit push rod 8 and the installation slot 403 are relatively staggered under normal conditions of the adjustment rod 4. When the universal clamping plate 3 is compressed or pulled, it cannot be separated from the ring frame outside the adjustment rod 4, which ensures that the universal clamping plate 3 will not be moved up and down by external force under normal conditions after the downward adjustment is completed.

[0027] In actual application, in the initial state, Figure 2 , Figure 4 and Fig.13 Taking the left figure as an example, when installing the universal clamping plate 3 on the right side, the adjusting rod 4 is driven to deflect a certain angle counterclockwise according to the adjusting hand wheel 401, so that the right installation groove 403 corresponds to the right limiting push rod 8. According to the cooperation of the guide limit block on the universal clamping plate 3 and the dovetail guide frame inside the box body 1, the universal clamping plate 3 can move downward and be placed in the storage module on the right side. In the process of the universal clamping plate 3 going down, the push rod slide 7 is adjusted to move down synchronously along the wedge-shaped guide frame 6. At the same time, the push rod slide 7 is adjusted to move closer to the placement groove 300 through the distance adjustment frame 14, so as to change the size of the actual working notch of the placement groove 300. When the placement groove 300 in the storage module is adjusted to a suitable notch size, the adjusting rod 4 is driven to rotate in the opposite direction by adjusting the hand wheel 401, and then the universal clamping plate 3 on the left side is installed in this way.

[0028] like Fig.12 As shown, when the left and right universal splints 3 are installed, the limit push rod 8 subjected to the elastic force of the push spring 12 will press against the distance-increasing arc block 400, and the two limit push rods 8 will eventually press against the arc-shaped ends of the distance-increasing arc block 400. The installation groove 403 and the limit push rod 8 are relatively staggered, ensuring that the ends of the limit push rod 8 are relatively far away from the installation groove 403 when the universal splint 3 is in a normal state. In this state, even if the universal splint 3 is pressed and tends to move downward, the limit push rod 8 cannot pass over the ring frame outside the adjustment rod 4, so the universal splint 3 will always maintain the adjusted height. When the limit push rod 8 presses against the outer side of the arc of the distance-increasing arc block 400, refer to Fig.13 As shown, at this time, the adjustment rod 4 is deflected counterclockwise by a certain angle, and the limit push rod 8 on the left side reaches the outer side of the arc of the distance-increasing arc block 400. Since the limit push rod 8 always has a tendency to move outward due to the elastic force of the push spring 12, when the limit push rod 8 reaches the outer side of the arc of the distance-increasing arc block 400, the adjustment rod 4 is forced to rotate clockwise under the guidance of the outer side of the arc until both limit push rods 8 reach the arc ends of the distance-increasing arc block 400.

[0029] Finally, when the universal splint 3 needs to be disassembled, the adjusting hand wheel 401 is used to rotate the adjusting rod 4 ninety degrees, which will make the reset groove 402 directly correspond to the limiting push rod 8. During this process, since the reset groove 402 cannot limit the movement of the limiting push rod 8, the adjusting push rod slide 7 pushed by the elastic force of the push spring 12 hits the inclined surface of the wedge-shaped guide frame 6, forcing the universal splint 3 to have an upward movement until the adjusting push rod slide 7 hits the top of the inclined surface of the wedge-shaped guide frame 6, making it convenient for the operator to directly take out the universal splint 3.

[0030] Embodiment 2 As a supplement to Embodiment 1, the box 1 is inevitably shaken during transportation. In order to effectively reduce the vibration of the reagent tubes placed in the placement slot 300, please refer to Figure 8 and Fig.10 It can be seen that a buffer assembly 5 is provided on the inner side of the box body 1, and the buffer assembly 5 includes a guide telescopic rod 502, an intermediate sleeve 500 is fixedly installed on the top of the guide telescopic rod 502, and a buffer spring 503 is provided on the outer side to push the intermediate sleeve 500 upward. In actual application, the guide telescopic rod 502 is a telescopic rod with an elliptical cross-section, which can limit the intermediate sleeve 500 to only reciprocating up and down motion. A "C"-shaped shielding sleeve 501 is fixedly connected to the top of the intermediate sleeve 500, and a buffer arm 504 that can reciprocate up and down along the central axis of the shielding sleeve 501 is movably installed on the outer side of the shielding sleeve 501. The buffer arm 504 is as shown in FIG. Fig.13 As shown in the right figure, the buffer arm 504 pushed by the elastic force of the buffer spring 503 is located at the bottom of the universal clamping plate 3, and the buffer arm 504 is located directly below the placement groove 300. The soft rubber pad fixed on the surface of the buffer arm 504 can Fig.13 The reagent tube A in the embodiment provides effective support. The advantage of the second embodiment is that Figure 8 As shown, the buffer arm 504 can move up and down along the shielding sleeve 501. Under normal conditions, the buffer arm 504 is located at the inner bottom of the shielding sleeve 501. Fig.10 It can be seen that when the universal splint 3 is installed in the storage module, its bottom will touch the top of the shielding sleeve 501 and be pushed by the shielding sleeve 501, which limits the existence of a certain distance between the bottom of the universal splint 3 and the buffer arm 504, thereby ensuring that the reagent tube A can be stably placed in the placement slot 300.

[0031] In the application of the second embodiment, according to Fig. 9 As shown, anti-collision cotton blocks 200 are arranged on the bottom of the box cover 2 and the box body 1. When the box cover 2 is closed on the top of the box body 1, as shown in FIG. Fig.10As shown, the anti-collision cotton block 200 at the bottom of the box cover 2 will hit the top of the reagent tube A. The reagent tube A will be pressed against the buffer arm 504 at the bottom. The buffer arm 504 will squeeze the buffer spring 503 through the intermediate sleeve 500 to ensure that the reagent tube A can be elastically clamped to avoid the problem of the reagent tube A being broken due to impact during transportation. It should be noted that when placing the reagent tubes A in the second embodiment, the reagent tubes A of the same height should be placed on the same buffer arm 504 to avoid the problem that the reagent tubes A on the buffer arm 504 cannot be effectively protected due to the height difference.

[0032] From the above, it can be seen that the technical means proposed in the second embodiment can provide elastic buffering during the transportation of the reagent tube A, thereby effectively protecting the reagent tube A.

[0033] The third embodiment is a further improvement on the basis of the second embodiment. It should be noted that the second embodiment can be implemented independently or used in conjunction with the third embodiment. Figure 6 and Figure 7 As shown, further limitations are made on the connection method of the push spring 12 in the third embodiment. A transmission gear 110 meshing with the outer teeth of the gear row slide 9 is movably installed on the inner side of the universal splint 3. The driving wheel 11 is coaxially and tightly installed on the rotating shaft of the transmission gear 110. Therefore, when the transmission gear 110 rotates one circle, the driving wheel 11 also rotates one circle. When the gear row slide 9 moves along the inner side of the universal splint 3, the meshing between the gear row slide 9 and the transmission gear 110 can force the driving wheel 11 to rotate synchronously. The diameter of the driving wheel 11 is 4-6 times the diameter of the transmission gear 110. In addition, a driven wheel 10 located on one side of the driving wheel 11 is movably installed on the inner side of the universal splint 3. The driven wheel 10 and the driving wheel 11 are connected by an endless belt transmission. According to actual selection, the endless belt can be a belt or a chain, and correspondingly, the driving wheel 11 / driven wheel 10 are pulleys / sprockets. The push spring 12 of the third embodiment is as shown in FIG. Figure 3 As shown, one end of the push spring 12 is fixed on the adjusting push rod slide 7, and the other end is fastened to the ring belt according to the bracket. Under the push of the elastic force of the push spring 12, the adjusting push rod slide 7 and the limiting push rod 8 still have a tendency to be pushed outward from the side of the universal splint 3.

[0034] On this basis, if Figure 5 and Figure 6As shown, there is a magnetic block 13 fixedly installed by a bracket on the side of the ring belt, and the magnetic block 13 can move synchronously with the ring belt. A magnetic groove 301 coaxially aligned with the shielding sleeve 501 is opened on the surface of the universal clamping plate 3. The diameter of the magnetic groove 301 is relatively smaller than the diameter of the shielding sleeve 501, and a metal column 505 is fixedly installed at the end of the buffer arm 504. When the magnetic block 13 moves to the magnetic groove 301, the magnetic block 13 can absorb the corresponding metal column 505 below through the magnetic groove 301. In order to prevent the magnetic block 13 from magnetically adsorbing the adjacent metal column 505, during the manufacturing process, the shielding sleeve 501 and the universal clamping plate 3 are made of materials that can shield magnetism, so that the adjacent metal column 505 can be prevented from being mistakenly attracted by the magnetic block 13.

[0035] In the third embodiment, when the universal clamping plate 3 is pressed downward to adjust the spacing between the slots 300, the method is consistent with that described in the first embodiment, and will not be described in detail here.

[0036] When it is necessary to take the reagent tube A in the placement slot 300, Figure 4 and Fig.13 It can be seen that by using the adjusting hand wheel 401 to deflect the adjusting rod 4 counterclockwise, the arc-shaped outer side of the distance-increasing arc block 400 will hit the limit push rod 8 on the left and retract it into the universal clamping plate 3. During this process, the moving gear row slide 9 can make the transmission gear 110 meshing with it drive the driving wheel 11 to rotate clockwise. On the one hand, the bracket on the ring belt will shorten the distance between it and the adjusting push rod slide 7, so that the push spring 12 is further compressed; on the other hand, the ring belt will drive the magnetic block 13 to move to the right. Due to the large difference in diameter between the driving wheel 11 and the transmission gear 110, when the transmission gear 110 is slightly deflected by the meshing of the gear row slide 9, the driving wheel 11 can drive the ring frame to move a larger displacement until the magnetic block 13 passes through the magnetic groove 301, and the metal column 505 attracted by the magnetism will lift the corresponding buffer arm 504 upwards, as shown in FIG. Fig.13 As shown on the right side, when the buffer arm 504 is lifted upward, the reagent tube A placed on the buffer arm 504 will be further lifted upward. The reagent tube A lifted by the buffer arm 504 is relatively protruding, and when the operator takes it, it will not touch the adjacent reagent tube A, so that it is convenient for the operator to take it. As the adjustment rod 4 continues to rotate counterclockwise, the magnetic block 13 will also continue to move to the right, so as to pass through the corresponding magnetic groove 301 in turn, ensuring that the operator can easily take the placed reagent tube A.

[0037] Moreover, reference Figure 4 , Figure 6 and Fig.14It can be seen that when the adjusting rod 4 rotates to nearly 90 degrees, the magnetic block 13 will hit the distance adjusting frame 14 and push it to move further to the right. If a reagent tube A is placed in the placement slot 300, the distance adjusting frame 14 will be blocked by the reagent tube A, and the distance adjusting frame 14 cannot move. The adjusting rod 4 will also be unable to rotate, and the limiting push rod 8 will not enter the reset groove 402. Finally, when there is a reagent tube A in the placement slot 300, the adjusting rod 4 cannot rotate 90 degrees, and the universal clamping plate 3 cannot be retracted. Similarly, when the reagent tube A in the placement slot 300 has been completely taken out, the adjusting rod 4 can be rotated to 90 degrees and hit the reset groove 402 through the limiting push rod 8. Afterwards, the adjusting push rod slide 7 hits the inclined surface of the wedge-shaped guide frame 6 to drive the universal clamping plate 3 to move upward, so that the universal clamping plate 3 can be taken out.
