Description

Technical Field

[0001] This utility model relates to the field of fluorescence quantitative analyzer technology, and in particular to a portable multi-channel fluorescence quantitative analyzer. Background Technology

[0002] A multichannel quantitative fluorescence analyzer is a high-precision instrument based on fluorescence detection technology, primarily used for quantitative analysis in biomedicine, molecular diagnostics, and precision medicine. It utilizes fluorescent dyes to generate fluorescence signals corresponding to specific wavelengths under a specific excitation light source. These signals are captured by a photoelectric sensor and converted into electrical signals, which are then processed by a computer for quantitative analysis. Each channel corresponds to a different fluorescence wavelength (e.g., 365nm–610nm), allowing for the simultaneous detection of multiple targets (such as genes and proteins) without interference, supporting multiplex PCR and combined detection requirements. With the increasing demand for precision medicine, this instrument will further optimize its multichannel combined detection capabilities and expand into areas such as pathogen detection and tumor marker screening, thereby improving detection efficiency and clinical application value.

[0003] However, in the existing technology, multi-channel fluorescence quantitative analyzers are large in size and can only be moved to the corresponding location by manual handling or transportation, which is very inconvenient. In addition, existing multi-channel fluorescence quantitative analyzers are not easy to store, and dust will accumulate on the upper part of the body when exposed to the air for a long time. Furthermore, the display screen of the multi-channel fluorescence quantitative analyzer has no protective measures and is easily scratched when subjected to external force, which greatly reduces the service life of the device. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable multichannel fluorescence quantitative analyzer includes a support mechanism, an analyzer body, and a cabinet for housing the analyzer body;

[0007] The bottom of the cabinet is recessed upward to form an accommodating space, and a support mechanism that can extend downward to support the cabinet is provided in the accommodating space. The support mechanism includes a positioning support component that can position and support the cabinet and a movable support component that can move and support the cabinet.

[0008] Furthermore, the positioning support assembly includes four electric cylinders, which are arranged in pairs, and each pair of electric cylinders has a first movable plate fixed to its bottom, with a damping support block fixed to its bottom.

[0009] Furthermore, the movable support assembly includes two sets of vertical rods symmetrically fixed in the accommodating space, and a second movable plate that can be raised and lowered is slidably sleeved on the vertical rods. At least two omnidirectional wheels are installed at equal intervals at the bottom of the second movable plate.

[0010] Furthermore, a T-shaped groove perpendicular to the second movable plate is provided in the accommodating space. Two sets of sliders are symmetrically distributed and slidably connected through the T-shaped groove. The two sets of sliders correspond one-to-one with the two sets of second movable plates, and a hinge plate is rotatably connected between the sliders and the movable plates.

[0011] Furthermore, the slider includes a T-shaped part connected to a T-shaped groove and a connecting part connected to a hinge plate, and the accommodating space is provided with a threaded rod that can spirally pass through the connecting part. The threaded rod has two threaded parts with opposite spiral directions, and the two threaded parts respectively pass through the connecting parts of the two sets of sliders.

[0012] Furthermore, a motor for driving the threaded rod selection is installed on one side of the cabinet, and the bottom of the vertical rod is fixed with a baffle that is flush with the bottom of the cabinet.

[0013] Furthermore, ventilation openings are provided on both sides of the cabinet, and a battery for powering the analyzer body and a controller electrically connected to the electric cylinder and motor are provided at the bottom of the cabinet.

[0014] Furthermore, the protective assembly includes a partition disposed above the analyzer body and a protective plate that can slide and rotate relative to the partition. The partition has a front end and a rear end, and the protective plate has a sliding end and a movable end.

[0015] Furthermore, when the sliding end of the protective plate slides to the rear end of the partition, the movable end of the protective plate is rotated and restricted above the partition; when the sliding end of the protective plate slides to the front end of the partition, the movable end of the protective plate rotates to the bottom of the partition.

[0016] Furthermore, two through slots are symmetrically opened on the cabinet above the partition, and a moving rod is fixed through the sliding end of the protective plate, with each end of the moving rod passing through one of the two through slots.

[0017] Furthermore, the movable rod is a cylindrical rod, and both ends of the cylindrical rod are fixed with discs located on the outside of the cabinet, so that the movable rod can rotate within the through groove.

[0018] Furthermore, a handle and an extension plate are fixedly installed on one side surface of the protective plate. Two slide rods are symmetrically fixedly installed on the bottom of the extension plate. A circular plate is fixedly installed on the bottom of each slide rod, and a sliding plate is slidably fitted on each slide rod. A spring fitted outside the slide rod is fixedly connected to the top and / or bottom of the sliding plate, and a U-shaped plate is fixedly connected between the two sliding plates. An L-shaped plate located below the protective plate and capable of passing through the U-shaped plate is installed on the cabinet.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. This utility model, by setting a support mechanism on the inner wall surface of the accommodating space, uses multiple electric cylinders to drive two damping support blocks to support the entire device off the ground, and a motor drives a bidirectional threaded rod to move two connecting plates away from each other. In conjunction with multiple hinge plates, it drives two second movable plates to move downward, thereby causing the lower ends of multiple casters to move out of the accommodating space. The two damping support blocks are then reset so that the multiple casters contact the ground, and then the cabinet can be pushed to move the multi-channel fluorescence quantitative analyzer body, thus facilitating the movement of the multi-channel fluorescence quantitative analyzer body to the corresponding location.

[0021] 2. This utility model provides protective components on the inner surfaces of both sides of the cabinet. The protective plate is moved by the handle, and the L-shaped plate is inserted into the L-shaped plate by pushing the U-shaped plate. The U-shaped plate is then locked inside the L-shaped plate by the reset of multiple springs, preventing the protective plate from moving. This completes the protection of the multi-channel fluorescence quantitative analyzer body, preventing dust accumulation and scratching the display screen. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-10This utility model provides a technical solution: a portable multi-channel fluorescence quantitative analyzer, comprising: a cabinet 1, an analyzer body 2 fixedly installed on the bottom inner wall surface of the cabinet 1, ventilation openings 3 on both sides of the cabinet 1, each ventilation opening 3 having a protective net fixed inside, a partition 4 fixedly installed on the top surface of the analyzer body 2, the three sides of the partition 4 being fixedly installed on the three sides of the inner wall surface of the cabinet 1, a receiving space 5 opened on the bottom surface of the cabinet 1, a support mechanism 8 provided on the top inner wall surface of the receiving space 5, and protective components 9 provided at the top of the two sides of the inner wall surface of the cabinet 1. The support mechanism 8 includes four electric cylinders 801, the four electric cylinders 801 being symmetrically fixedly installed in pairs on the top inner wall surface of the receiving space 5.

[0035] Specifically: A protective net is fixedly installed on the inner wall surface of the ventilation vent 3 to prevent dust from entering the cabinet 1. The analyzer body 2 is a high-precision instrument based on fluorescence detection technology, which is mainly used for quantitative analysis in the fields of biomedicine, molecular diagnostics and precision medicine. Details will not be described here.

[0036] In one embodiment, a battery 6 is embedded on the left side of the lower end of one side surface of the cabinet 1, and a controller 7 is fixed on the right side of the lower end of one side surface of the cabinet 1.

[0037] Specifically, such as Figure 1 As shown: The storage battery 6 provides power to the analyzer body 2, controller 7, multiple electric cylinders 801 and motor 809. The controller 7 controls the motor 809 and multiple electric cylinders 801.

[0038] In one embodiment, each of the four electric cylinders 801 is fixedly mounted with a first movable plate 802 at the output end of each pair, and a damping support block 803 is fixedly mounted on the bottom surface of each of the two first movable plates 802.

[0039] Specifically, such as Figure 3 and 6 As shown: Multiple electric cylinders 801 drive the two first movable plates 802 and the damping support blocks 803 to move. When the two damping support blocks 803 contact the ground, they work with the electric cylinders 801 to lift the entire device.

[0040] In one embodiment, two baffles 804 are symmetrically fixedly installed at the bottom of the inner wall surfaces on both sides of the accommodating space 5. Vertical rods 805 are fixedly installed between the top surfaces of the baffles 804 and the top inner wall surfaces of the accommodating space 5. The surfaces of the vertical rods 805, which are in pairs, are movably fitted with second movable plates 806. Universal wheels 807 are installed at both ends of the bottom surfaces of the two second movable plates 806.

[0041] Specifically, such as Figure 4-5 As shown: the baffle 804 prevents the second movable plate 806 from detaching from the vertical rod 805, and the multiple casters 807 assist in moving the analyzer body 2. When the second movable plate 806 moves to the bottom of the vertical rod 805, the multiple electric cylinders 801 extend and retract to their longest length, and the height of the multiple casters 807 is always higher than the two damping support blocks 803.

[0042] In one embodiment, a threaded rod 808 is rotatably mounted on the center of the inner wall surface on both sides of the accommodating space 5 via a bearing, and a motor 809 is fixedly mounted on the center of the lower end of one side surface of the cabinet 1. The output end of the motor 809 movably passes through one side surface of the cabinet 1 and is fixedly mounted on one end surface of the threaded rod 808.

[0043] Specifically, such as Figure 4 As shown: Motor 809 is a forward and reverse rotating motor 809, which plays the role of driving the threaded rod 808 to rotate forward and reverse.

[0044] In one embodiment, two T-slots 810 are symmetrically opened on the top inner wall surface of the accommodating space 5. Two T-shaped parts are movably fitted inside each of the two T-slots 810. A connecting part 812 is fixedly installed between each pair of T-shaped parts. The T-shaped parts and the connecting parts 812 are combined to form a slider 811. Both connecting parts 812 are threaded onto the outer wall surface of the threaded rod 808.

[0045] Specifically, such as Figure 4 As shown: the connecting part 812 moves with the help of the slider 811 and the threaded rod 808. The threaded rod 808 drives the two connecting parts 812 to move in opposite directions.

[0046] In one embodiment, the bottom surfaces of the two connecting portions 812 are symmetrically hinged with two hinge plates 813, and the ends of the multiple hinge plates 813 away from the two connecting portions 812 are correspondingly hinged to one side surface of the two second movable plates 806.

[0047] Specifically, such as Figure 4 As shown: Multiple hinge plates 813 drive two second movable plates 806 to move up and down on the surface of multiple vertical rods 805. When the two connecting parts 812 move to the extreme ends of the threaded rod 808, the multiple hinge plates 813 are always in an inclined state during this process.

[0048] In one embodiment, the protective component 9 includes two through slots 901, which are respectively opened through the upper ends of the two side surfaces of the cabinet 1. Both through slots 901 are located on the upper side of the partition 4. A movable rod 902 is movably fitted through the inside of the two through slots 901. Both ends of the outer wall surface of the movable rod 902 are fixedly fitted with discs 903. One side surface of the two discs 903 is movably fitted with the two side surfaces of the cabinet 1. A protective plate 904 is fixedly fitted on the outer wall surface of the movable rod 902. A handle 905 is fixedly installed on one side surface of the protective plate 904. An L-shaped plate 906 is fixedly installed at the lower end of the other side surface of the cabinet 1.

[0049] Specifically, such as Figure 1 , 7 As shown in Figure 9: the two discs 903 prevent the moving rod 902 from disengaging from the two through slots 901, while ensuring that the moving rod 902 can move stably. The two side surfaces and the bottom surface of the protective plate 904 correspond to and are in contact with multiple inner wall surfaces of the cabinet 1. The protective plate 904 serves to close the opening of the cabinet 1.

[0050] In one embodiment, an extension plate 907 is fixedly installed on one side surface of the protective plate 904 near the edge. Two slide rods 908 are symmetrically fixedly installed on the bottom surface of the extension plate 907. A circular plate 909 is fixedly installed on the bottom surface of each slide rod 908. A sliding plate 910 is movably fitted onto the surface of each slide rod 908.

[0051] Specifically, such as Figure 10 As shown: the two circular plates 909 serve to prevent the two sliding plates 910 from detaching from the two sliding rods 908.

[0052] In one embodiment, springs 911 are fixedly installed between the upper and lower side surfaces of the two slide plates 910 and the top surface of the two circular plates 909 and the bottom surface of the extension plate 907. Two slide rods 908 are located on the inner side of the plurality of springs 911. A U-shaped plate 912 is fixedly installed between the other side surfaces of the two slide plates 910. The bottom inner wall surface of the U-shaped plate 912 is movably attached to the top inner wall surface of the L-shaped plate 906.

[0053] Specifically, such as Figure 10 As shown: Spring 911 restricts the position of slide plate 910 on the surface of slide bar 908, and the U-shaped plate 912, together with L-shaped plate 906, prevents the protective plate 904 from rotating.

[0054] Working principle:

[0055] When using this multi-channel fluorescence quantitative analyzer, when it is necessary to move the multi-channel fluorescence quantitative analyzer, firstly, the controller 7 operates multiple electric cylinders 801. The operation of multiple electric cylinders 801 drives two first movable plates 802 to move downwards. The movement of the two first movable plates 802 drives two damping support blocks 803 to move downwards. The multiple electric cylinders 801 continuously extend, thereby driving the entire multi-channel fluorescence quantitative analyzer to lift off the ground.

[0056] At this time, the controller 7 operates the motor 809, which drives the threaded rod 808 to rotate. The two connecting parts 812 move with the help of multiple T-plates and the threaded rod 808. The rotation of the threaded rod 808 drives the two connecting parts 812 to move away from each other. The movement of the two connecting parts 812 drives multiple hinge plates 813 to move. The movement of the multiple hinge plates 813 drives two second movable plates 806 to move downward on the surface of multiple vertical rods 805. The movement of the two movable plates 806 drives multiple casters 807 to move downward. When the multiple casters 807 are disengaged from the interior of the receiving space 5, the motor 809 can be stopped. Then, the controller 7 operates multiple electric cylinders 801 to reset the two damping support blocks 803, so that the multiple casters 807 contact the ground. Then, the entire analyzer body 2 can be moved by the moving cabinet 1.

[0057] With the cooperation of the above structure, multiple electric cylinders 801, together with two damping support blocks 803, support the entire device off the ground. Multiple casters 807 can assist the movement of the entire device, making it convenient to move the analyzer body 2 to the corresponding location.

[0058] When it is necessary to protect the analyzer body 2 when it is not in use, first pull the protective plate 904 by the handle 905. The movement of the protective plate 904 causes the moving rod 902 to move inside the two through slots 901. When the moving rod 902 moves to the extreme of one end of the two through slots 901, the protective plate 904 is rotated and the U-shaped plate 912 is pulled. The movement of the U-shaped plate 912 causes the two sliding plates 910 to move on the surface of the two sliding rods 908. The movement of the two sliding plates 910 will squeeze and stretch multiple springs 911, so that multiple springs 911 are compressed or stretched. When the protective plate 904 is completely inside the cabinet 1, the L-shaped plate 906 penetrates the inside of the U-shaped plate 912. Then the U-shaped plate 912 is released. The rebound force of multiple springs 911 makes the bottom inner wall surface of the U-shaped plate 912 tightly fit the top inner wall surface of the L-shaped plate 906, thereby restricting the protective plate 904 to one side opening of the cabinet 1.

[0059] With the cooperation of the above structures, when it is not suitable for a multi-channel fluorescence quantitative analyzer, the protective plate 904 is restricted to one side opening of the cabinet 1 by the cooperation of the U-shaped plate 912 and the L-shaped plate 906, thus sealing the cabinet 1, preventing dust accumulation and preventing the display screen from being scratched.

[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
