In the description of the present invention, the meanings of "multiple" and "several" are two or more, unless otherwise clearly and specifically defined.

[0028] Please also read Figure 1 and Figure 6, now an alarm reagent tray provided by the utility model is described. The alarm reagent tray includes a bracket 1 and a bracket 2, the bracket 1 has an installation cavity 11 opening upward, and the bracket 1 is connected to a support plate 12 blocking the upper opening of the installation cavity 11; the bracket 2 is connected to the upper part of the bracket 1, and a partition plate assembly 3 is provided in the bracket 2, and the partition plate assembly 3 and the bracket 2 are enclosed to form a plurality of accommodating cavities 21 located above the support plate 12, and the accommodating cavities 21 are used to store reagent bottles 10; wherein, a plurality of proximity switches 4 are connected in the installation cavity 11, and a plurality of through holes 121 corresponding to the accommodating cavities 21 are provided on the support plate 12, and the detection end of the proximity switch 4 extends into the through hole 121, and is used to detect whether there is a reagent bottle 10 in the accommodating cavity 21, and the bracket 1 is connected to a timer 5 and a controller electrically connected to the proximity switch 4, respectively, and the controller is used to receive the detection signal of the proximity switch 4 and generate a timing instruction to send to the timer 5, and the timer 5 is used to send a timing reminder signal.

[0029] The present embodiment provides an alarm reagent tray. Compared with the prior art, the partition plate assembly 3 is used to divide the interior of the bracket 2 into a plurality of relatively independent accommodating chambers 21, and the reagent bottle 10 is placed in the accommodating chamber 21, thereby avoiding mutual collision and friction between the reagent bottles 10 and ensuring the safety of the reagent bottle 10. At the same time, a proximity switch 4 is arranged in the mounting chamber 11 of the bracket 1, so that the detection end of the proximity switch 4 is docked with the accommodating chamber 21 through the through hole 121 on the support plate 12 to detect whether the reagent bottle 10 is stored in the accommodating chamber 21. If the proximity switch 4 does not detect the reagent bottle 10, the timer 5 is used to time. If the reagent bottle 10 is still not returned after exceeding the preset time, the timer 5 sends an alarm signal to remind the operator. Through the above structure, the storage management of the reagent bottle 10 is realized, the loss of the reagent bottle 10 is avoided, and the practicality of the reagent tray is improved.

[0030] It should be noted that the proximity switch 4 is a position switch that does not need to be in direct contact with the object to be detected. When the object approaches the detection end, the proximity switch 4 can be activated. It has reliable operation, stable performance, and has the characteristics of being waterproof and corrosion-resistant. In this embodiment, the proximity switch 4 adopts a capacitive proximity switch 4, which can detect reagent bottles 10 of various materials. In actual use, the distance between the detection end of the proximity switch 4 and the top surface of the support plate 12 can be determined according to the sensitivity of the proximity switch 4 to ensure that the proximity switch 4 can detect the storage status of the reagent bottle 10.

[0031] First, the proximity switch 4 is connected to the installation cavity 11, and then the support plate 12 is connected to the upper part of the bracket 1. In some specific implementations, a card slot can be provided on the upper edge of the bracket 1, and a card strip can be provided on the bottom surface of the support plate 12. The connection between the support plate 12 and the bracket 1 is achieved by inserting the card strip into the card slot.

[0032] The bracket 2 and the bracket 1 can be connected by the above-mentioned card strip and card slot, or by providing a lock buckle on the outer wall. Further, handles can be provided on both side walls of the bracket 1 to facilitate the operator to carry.

[0033] The supporting plate 12 plays the role of supporting the reagent bottle 10. At the same time, the through hole 121 on the supporting plate 12 can guide the detection end of the proximity switch 4 to the bottom of the reagent bottle 10 to detect the storage of the reagent bottle 10. When using the reagent bottle 10 to pour chemical reagents, some chemical reagents are often retained on the bottle body of the reagent bottle 10. The chemical reagents retained on the bottle body of the reagent bottle 10 can be diverted to the installation cavity 11 through the through hole 121 to avoid leakage of chemical reagents and pollution to the surrounding environment. Further, a dust cover can be set above the bracket 2 to avoid the entry of dust and to avoid the evaporation of the chemical reagents flowing into the installation cavity 11, causing environmental pollution.

[0034] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figure 1 and Figure 2 The bracket 2 and the bracket 1 are both rectangular components. The partition plate assembly 3 includes a transverse partition 31 extending along the long side of the bracket 2 and a plurality of longitudinal partitions 32 arranged perpendicular to the transverse partition 31. One side edge of the longitudinal partition 32 is connected to the transverse partition 31, and the other side edge is connected to the inner wall of the bracket 2.

[0035] In this embodiment, the transverse partition 31 is arranged parallel to the long side of the bracket 2, and its two ends are respectively connected to the two end plates of the bracket 2. The transverse partition 31 first divides the interior of the bracket 2 into two long chambers arranged along the wide side of the bracket 2, and a plurality of longitudinal partitions 32 are arranged at intervals in the above-mentioned long chambers, and divide the above-mentioned long chambers into a plurality of accommodating chambers 21.

[0036] By providing the above-mentioned one transverse partition 31 and a plurality of longitudinal partitions 32, each accommodating cavity 21 has a cavity wall which is the side wall of the bracket 2. Thus, a label 8 can be provided at a position of the outer wall of the bracket 2 corresponding to the accommodating cavity 21 to display the information of the chemical reagent in the reagent bottle 10. Specifically, the label 8 is a magnetic label, which is convenient for taking, placing and replacing the label 8.

[0037] Furthermore, the sizes of the accommodating chambers 21 can be the same or different, which can be determined according to the actual usage scenario. In this embodiment, the interior of the bracket 2 is divided into twelve accommodating chambers 21 of the same size by a transverse partition 31 and ten longitudinal partitions 32, and a magnetic tag 8 is provided on the outer wall of the bracket 2 corresponding to each accommodating chamber 21.

[0038] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figures 2 to 4Two clamping seats 22 that can approach each other are slidably connected in the accommodating cavity 21. The clamping seats 22 have clamping grooves 221 that can clamp the outer periphery of the reagent bottle 10. The clamping seats 22 are used to clamp and limit the reagent bottle 10 at the center position of the accommodating cavity 21.

[0039] In this embodiment, in order to make the accommodating chamber 21 adapt to the storage of reagent bottles 10 of different sizes, a pair of clamping bar seats 22 with clamping grooves 221 are provided, and the two clamping bar seats 22 can slide and approach the center position of the accommodating chamber 21 synchronously, so that the clamping grooves 221 can clamp the outer periphery of the reagent bottle 10, and prevent the reagent bottle 10 from shaking in the accommodating chamber 21 during operation. Clamping the reagent bottle 10 at the center position of the accommodating chamber 21 helps to increase the clamping range of the clamping bar seats 22.

[0040] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figure 3 The through hole 121 is located at the center of the accommodating cavity 21 , and the main axis of the proximity switch 4 coincides with the main axis of the through hole 121 .

[0041] In this embodiment, the through hole 121 is located at the center of the accommodating cavity 21, so that the main axis of the proximity switch 4 can be coaxially arranged with the reagent bottle 10 located at the center of the accommodating cavity 21. Through the above arrangement, even if reagent bottles 10 of different sizes are replaced in the same accommodating cavity 21, the proximity switch 4 always remains coaxially located at the bottom of the reagent bottle 10, so as to ensure the reliability of the proximity switch 4 in detecting the reagent bottle 10.

[0042] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figure 2 A guide rod 23 and a bidirectional screw 24 are rotatably connected to the side cavity wall of the accommodating cavity 21, which are respectively arranged along the extension direction of the longitudinal partition 32. One end of the clamping bar seat 22 is slidably connected to the guide rod 23, and the other end is threadedly connected to the bidirectional screw 24. The bidirectional screw 24 can drive the two clamping bar seats 22 to move toward each other so that the clamping groove 221 is clamped on the outer periphery of the reagent bottle 10, and can also drive the two clamping bar seats 22 to move back to back so that the clamping groove 221 is away from the reagent bottle 10. The outer end of the bidirectional screw 24 is set through the side wall of the bracket 2.

[0043] In this embodiment, the two ends of the guide rod 23 are respectively rotatably connected to the transverse partition 31 and the side wall of the bracket 2, the inner end of the bidirectional screw 24 is rotatably connected to the transverse partition 31, and the outer end extends outward to penetrate the side wall of the bracket 2. Furthermore, the outer end of the bidirectional screw 24 is connected to a handwheel to facilitate the operator to rotate the bidirectional screw 24.

[0044] The bidirectional screw 24 is provided with two symmetrically arranged and oppositely rotating threaded parts, and the two clamping bar seats 22 are threadedly connected to the two threaded parts one by one, so that when the bidirectional screw 24 is rotated, the two clamping bar seats 22 can approach each other or move away from each other under the guidance of the guide rod 23.

[0045] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figure 3 and Figure 4 An inwardly concave avoidance groove 222 is provided on the groove wall of the clamping groove 221, and an elastic clamping member 25 is provided in the avoidance groove 222. The elastic clamping member 25 has an arc-shaped abutting surface 2511 protruding from the groove wall of the clamping groove 221 and elastically abutting against the outer periphery of the reagent bottle 10.

[0046] In this embodiment, when the diameters of different reagent bottles 10 vary widely, the reagent bottle 10 can be further clamped by the elastic clamping member 25 provided in the clamping groove 221. Specifically, the bidirectional screw 24 is rotated, and when the two clamping bar seats 22 slide toward each other to a diameter close to that of the reagent bottle 10, the rotation of the bidirectional screw 24 is stopped. At this time, the reagent bottle 10 is placed between the two clamping bar seats 22. Since the arc-shaped abutting surface 2511 on the elastic clamping member 25 protrudes from the groove wall of the clamping groove 221, the arc-shaped abutting surface 2511 can further abut and clamp the reagent bottle 10. On the other hand, the arc-shaped setting of the arc-shaped abutting surface 2511 will not hinder the removal of the reagent bottle 10, ensuring that the process of taking and placing the reagent bottle 10 is more stable.

[0047] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figure 4 The elastic clamping member 25 includes a rotating shaft 253, an arc-shaped abutting block 251 rotatably connected to the rotating shaft 253, and a torsion elastic member 252 sleeved on the outer periphery of the rotating shaft 253. The two ends of the torsion elastic member 252 are respectively connected to the groove wall of the avoidance groove 222 and the arc-shaped abutting block 251. The arc-shaped abutting surface 2511 is arranged on the arc-shaped abutting block 251. The torsion elastic member 252 is used for elastically pushing the arc-shaped abutting block 251 to swing vertically so that the arc-shaped abutting surface 2511 abuts against the outer periphery of the reagent bottle 10.

[0048] In this embodiment, when the torsion elastic member 252 is reset, the arcuate abutment surface 2511 radially protrudes from the groove wall of the clamping groove 221. As the reagent bottle 10 is placed, the reagent bottle 10 squeezes the arcuate abutment block 251 to swing into the avoidance groove 222, so that the torsion elastic member 252 is compressed to generate a reaction force, so that the arcuate abutment surface 2511 abuts against the outer periphery of the reagent bottle 10. When the reagent bottle 10 is taken out, due to the arcuate setting of the arcuate abutment surface 2511, it will not interfere with the removal process of the reagent bottle 10. As long as the pulling force applied to the reagent bottle 10 is greater than the friction between the arcuate abutment surface 2511 and the reagent bottle 10, the reagent bottle 10 can be taken out.

[0049] Furthermore, the arcuate abutment block 251 is made of rubber material, or a rubber pad is only provided on the arcuate abutment surface 2511 to increase the friction between the arcuate abutment surface 2511 and the reagent bottle 10, thereby achieving the effect of stably taking and placing the reagent bottle 10, and preventing the body of the reagent bottle 10 from being scratched.

[0050] Specifically, the torsion elastic member 252 is a torsion spring.

[0051] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figure 5 and Figure 6 A mounting bracket 6 is provided in the mounting cavity 11, and the mounting bracket 6 includes a sliding plate 61 slidably connected to the bracket 2 along the up and down directions and a support plate 62 connected to the upper end of the sliding plate 61, the support plate 62 extends in the horizontal direction, and the proximity switch 4 is connected to one end of the support plate 62 away from the sliding plate 61.

[0052] It should be noted here that the outer periphery of the existing proximity switch 4 is provided with a connecting thread and is equipped with two mounting nuts. When installing the proximity switch 4, it is necessary to thread the proximity switch 4 onto the support plate 62, and thread the two mounting nuts onto the upper and lower sides of the support plate 62, respectively. After the proximity switch 4 is installed, if the distance between the detection end of the proximity switch 4 and the top surface of the support plate 12 is to be adjusted, it is necessary to loosen the two mounting nuts in turn, and then rotate the proximity switch 4 to adjust the installation height of the proximity switch 4 on the support plate 62. The setting of the mounting bracket 6 in this embodiment can achieve the adjustment of the installation height of the proximity switch 4 through the sliding connection between the sliding plate 61 and the bracket 1, thereby fine-tuning the detection distance.

[0053] In this embodiment, the sliding plate 61 and the supporting plate 62 form an "L"-shaped mounting bracket 6, and the supporting plate 62 is provided with threaded holes running through the upper and lower parts to facilitate threaded connection with the proximity switch 4; the setting of the sliding plate 61 can increase the area of ​​sliding connection with the bracket 1, thereby ensuring the stability of the mounting bracket 6 during sliding.

[0054] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figure 3 , Figure 5 and Figure 6 The bracket 1 is provided with two slide rails 13 extending in the up-down direction respectively, and the slide plate 61 is slidably connected to the slide rails 13; the slide plate 61 has a toothed portion 611 extending in the up-down direction, and the bracket 1 is rotatably connected with a gear 14 for driving the slide plate 61 to slide up and down, the gear 14 is meshed with the toothed portion 611, and the gear 14 is rotatably connected to the bracket 1 through an extension shaft 15, and the extension shaft 15 is horizontally arranged to penetrate the bracket 1 outward.

[0055] In this embodiment, the extension shaft 15 is rotated and the gear 14 rotates synchronously. Through the meshing action between the gear 14 and the toothed portion 611, the sliding plate 61 is driven to slide up and down along the slide rails 13 on both sides, and then the proximity switch 4 is driven to move up and down through the support plate 62, thereby realizing the adjustment of the detection distance of the proximity switch 4.

[0056] Specifically, a positioning structure (not shown in the figure) is provided on the extension shaft 15. When the sliding plate 61 slides to a suitable position, the positioning mechanism can fix the extension shaft 15 and restrict its rotation, so as to fix the proximity switch 4 at a suitable height. The positioning structure can adopt a locking block and a locking bolt structure, which is a prior art and will not be described in detail here.

[0057] As a specific implementation of a reagent tray capable of alarming provided by the utility model, see Figure 1 The bracket 1 is connected with a plurality of indicator lights 7 electrically connected to the controller. The indicator lights 7 are arranged one by one corresponding to the proximity switches 4 and are used to indicate the storage status of the reagent bottles 10 in the accommodating chamber 21 .

[0058] In this embodiment, the indicator light 7, the timer 5 and the proximity switch 4 are all electrically connected to the controller. In actual use, the indicator lights 7 can be numbered to correspond to the accommodating chambers 21. When reagent bottles 10 are stored in each accommodating chamber 21, all the proximity switches 4 are powered on and all the indicator lights 7 are lit; when a reagent bottle 10 is taken out, the corresponding proximity switch 4 is disconnected, the corresponding indicator light 7 is turned off, and the timer starts timing. If the proximity switch 4 still fails to detect the reagent bottle 10 after the set time, the timer sends an alarm reminder signal to remind the relevant operator, thereby avoiding the loss of the reagent bottle 10.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
