Description

Technical Field

[0001] This invention relates to the field of biochemical detection instrument technology, and in particular to a fluorescence spectrometer that is easy to use outdoors. Background Technology

[0002] Fluorescence spectrometers, also known as fluorescence spectrophotometers, are used to detect substances and measure the interactions between small molecules and nuclei. With the continuous development of technology, fluorescence spectrometers are widely used in the detection of precious metals, coatings, and alloys. When using a fluorescence spectrometer, the operator needs to carry the equipment and place it in an easily accessible location or on a platform. After ensuring its stability, the equipment can be turned on. Especially when using a fluorescence spectrometer outdoors, it is difficult to quickly set it up. Generally, the fluorescence spectrometer is placed on the ground, requiring the operator to squat down to operate it, which increases the complexity of the operation and makes it inconvenient to use.

[0003] Therefore, in order to address the above problems, a fluorescence spectrometer that can be quickly erected using outdoor trees and clamped and fixed to the trees is being developed for easy outdoor use. Summary of the Invention

[0004] To overcome the shortcomings of existing devices that typically require the fluorescence spectrometer to be placed on the ground for outdoor use, necessitating operators to squat down to operate the spectrometer, thus increasing the complexity and inconvenience of operation, this invention provides a fluorescence spectrometer that can be quickly erected using outdoor trees and secured by clamping the tree, making it convenient for outdoor use.

[0005] The technical solution of the present invention is: a fluorescence spectrometer that is easy to use outdoors, comprising a first protective frame, a fluorescence spectrometer, a transparent plate, a second protective frame, a fixing mechanism, and a support mechanism. The fluorescence spectrometer is placed inside the first protective frame. A transparent plate for easy viewing by the operator is connected to the left side of the first protective frame. The second protective frame is connected to the front side of the first protective frame. The first protective frame is provided with a fixing mechanism for clamping and fixing trees. The first protective frame is provided with a support mechanism for improving the stability of the support.

[0006] Furthermore, the fixing mechanism includes a fixing plate, a pressure plate, a first gear, a second gear, a toothed frame, a fixing frame, a first fixing block, a second fixing block, a retaining ring, and a first spring. The upper right side of the first protective frame is rotatably connected to symmetrical fixing plates for clamping the tree. Each fixing plate is rotatably connected to two symmetrical pressure plates for clamping the tree. The top of the left pressure plate is connected to a first gear, and the top of the right pressure plate is connected to a second gear. The first gear meshes with the adjacent second gear. The two fixing plates... Each plate has a fixed frame connected to its top. Each fixed frame has a toothed frame that can mesh with the adjacent second gear. Each toothed frame is connected to the adjacent fixed frame by a first spring. Each first spring is wound around the adjacent fixed frame and can buffer and reset the adjacent toothed frame. Each fixed plate has a first fixed block connected to its upper left side and a second fixed block connected to its upper left side. Each first fixed block is located behind the second fixed block. Each second fixed block has a retaining ring that is rotatably connected to it for engaging the adjacent first fixed block.

[0007] Furthermore, the support mechanism includes a first fixing member, a first support plate, a first fixing frame, a second spring, a blocking member, and a torsion spring. The first fixing member is connected to the right side of both the front and rear parts of the first protective frame. The first support plate for supporting and clamping the tree is rotatably connected between the first fixing members. The first fixing frame is connected to the upper right side of the first protective frame. The blocking member for blocking and limiting the first support plate is slidably connected to both the front and rear parts of the first fixing frame. The blocking member can be pushed by the adjacent fixing plate. The second spring is connected between the blocking member and the first fixing frame. The second spring is installed inside the first fixing frame. The torsion spring is connected between the first support plate and the adjacent first fixing member. The torsion spring is wound around the first support plate.

[0008] Furthermore, it also includes a lifting mechanism, which includes a second fixing member, a first sliding member, a second support plate, a drive motor, a pulley assembly, a lead screw, and a connecting rod. The first fixing member is connected to the bottom right side of the first protective frame. Lead screws are rotatably connected to both the front and rear sides of the bottom of the first protective frame. First sliding members are threadedly connected to the lead screws. The first sliding members are slidably connected to the first protective frame. Connecting rods are rotatably connected to the second fixing member and the first sliding members. Adjacent connecting rods are rotatably connected. A second support plate for supporting the fluorescence spectrometer is slidably connected between the tops of the connecting rods. The drive motor is connected to the bottom left side of the first protective frame. A pulley assembly is connected between the output shaft of the drive motor and the lead screw.

[0009] Furthermore, it also includes a limiting mechanism, which includes a connector, a second sliding member, a limiting member, and a third spring. The first sliding members are connected to the side away from each other by a connector. The right side of each connector is connected to a second sliding member for limiting and locking the first support plate. The front and rear sides of the first protective frame are connected to limiting members for limiting adjacent second sliding members. The second sliding members are slidably connected to the adjacent limiting members. A third spring is connected between each second sliding member and the adjacent limiting member. The third spring can buffer and reset the second sliding member.

[0010] Furthermore, it also includes a locking mechanism, which includes a third fixing member and a locking member. The top of each fixing frame is connected to the third fixing member, and the top of each toothed frame is opened with a locking groove. Each third fixing member is rotatably connected with a locking member for engaging with the locking groove.

[0011] Furthermore, it also includes a placement mechanism, which includes a second fixed frame and a placement rack. The second fixed frame is connected to the front side of the first protective frame, and a placement rack for placing test tubes is slidably connected to the second fixed frame.

[0012] Furthermore, the top of each blocking component has a rounded arc shape.

[0013] Furthermore, the pulley assembly includes pulleys and a drive belt. The output shaft of the drive motor and the left side of the lead screw are both connected to pulleys, and a drive belt is wound between adjacent pulleys.

[0014] Furthermore, the right end of each card has a hook-shaped structure.

[0015] Compared with the prior art, the beneficial effects are: 1. The present invention unlocks the first and second fixing blocks by operating the retaining ring, and then the toothed frame drives the first and second gears to rotate, thereby unfolding the pressure plate. Then, the fixing plate is controlled to rotate to clamp and fix the tree, and the toothed frame is released so that the pressure plate cooperates with the fixing plate to clamp and stabilize the tree, thus achieving the effect of allowing the operator to operate the fluorescence spectrometer in a standing position outdoors.

[0016] 2. The present invention pushes the blocking member by rotating the fixed plate, thereby contacting the locking state of the first support plate. Then, the first support plate automatically flips under the action of the torsion spring, thereby supporting the device and improving the support stability of the device.

[0017] 3. This invention drives the output shaft of the drive motor to rotate the pulley assembly, thereby causing the lead screw to start rotating. As the lead screw rotates, the first sliding member moves closer to the first fixed member, causing the connecting rod to rotate and retract, which in turn pushes the second support plate to move upward, achieving the effect of automatically raising the position of the fluorescence spectrometer, making it convenient for operators to quickly operate and use the fluorescence spectrometer.

[0018] 4. The present invention uses the first sliding member to drive the connecting member to move to the right, so that the second sliding member slides to the right, thereby limiting and locking the first support plate after it is flipped and unfolded, and preventing the first support plate from accidentally flipping and resetting.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] A fluorescence spectrometer suitable for outdoor use, such as Figure 1 and Figure 2 As shown, it includes a first protective frame 1, a fluorescence spectrometer 2, a transparent plate 3, a second protective frame 4, a fixing mechanism 5, and a supporting mechanism 6. The fluorescence spectrometer 2 is placed inside the first protective frame 1. The transparent plate 3 is connected to the left side of the first protective frame 1. The second protective frame 4 is connected to the front side of the first protective frame 1. The fixing mechanism 5 and the supporting mechanism 6 are provided on the first protective frame 1.

[0031] It should be noted that when conducting small molecule-nucleus interaction studies outdoors, a fluorescence spectrometer 2 is required for detection. First, the device is fixed to a tree by unfolding the fixing mechanism 5, which facilitates operation. The transparent plate 3 allows the operator to observe the fluorescence spectrometer 2 in real time and determine whether it is working properly. Then, the support mechanism 6 is unfolded to further improve the stability of the device and prevent it from falling. After installation, the small molecule-nucleus interaction study can be conducted using the fluorescence spectrometer 2.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the fixing mechanism 5 includes a fixing plate 51, a pressure plate 52, a first gear 53, a second gear 54, a toothed frame 55, a fixing frame 56, a first fixing block 57, a second fixing block 58, a retaining ring 59, and a first spring 510. The upper right side of the first protective frame 1 is rotatably connected to two symmetrically arranged fixing plates 51. The fixing plates 51 are used to engage with the tree. Two symmetrically arranged pressure plates 52 are rotatably connected to each fixing plate 51. The pressure plates 52 are used to clamp the tree. The top of the left pressure plate 52 is connected to a first gear 53, and the top of the right pressure plate 52 is connected to a... The second gear 54 and the first gear 53 are both meshed with the adjacent second gear 54. The top of each of the two fixing plates 51 is connected to a fixing frame 56. Each fixing frame 56 is slidably connected to a toothed frame 55 that can mesh with the adjacent second gear 54. Each toothed frame 55 is connected to the adjacent fixing frame 56 by a first spring 510. Each fixing plate 51 is connected to the upper left side of the left side of the fixing plate 51 and to the upper left side of the fixing plate 51. Each fixing plate 51 is connected to a second fixing block 58. Each second fixing block 58 is rotatably connected to a retaining ring 59, which is used to engage the adjacent first fixing block 57.

[0033] It should be noted that when using the fluorescence spectrometer 2 outdoors, placing it directly on the ground is inconvenient, requiring the operator to squat down. To improve ease of outdoor use, the retaining ring 59 located at the junction of the two fixing plates 51 can be rotated and flipped up, so that the first fixing block 57 and the second fixing block 58, which are close to each other, are no longer locked. Then, by pulling the toothed frame 55 to the left, the first spring 510 is compressed. At this time, the toothed frame 55 will drive the adjacent second gear 54 to rotate, and the second gear 54 will drive the adjacent first gear 53 to rotate. The pressure plates 52 will rotate and unfold to the side away from each other. After the pressure plates 52 have rotated and unfolded, the fixing plates 51 are rotated 180 degrees, so that the first fixing blocks 57 and the second fixing blocks 58, which were originally close to each other, move away from each other and move closer together. At this time, rotating the retaining ring 59 will make the first fixing blocks 57 and the second fixing blocks 58, which were originally far apart, move closer together. The fixing block 57 and the second fixing block 58 enter the locking state. After locking, the toothed frame 55 is released. Under the action of the first spring 510, the toothed frame 55 will slide back to its original position and drive the second gear 54 to rotate back to its original position. At this time, the second gear 54 will drive the adjacent first gear 53 to rotate back to its original position, so that the pressure plate 52 will rotate back to the side closer to each other and cooperate with the fixing plate 51 to clamp and fix the tree. This makes it convenient for the operator to operate the fluorescence spectrometer 2 in a standing position outdoors. In summary, by operating the retaining ring 59, the first fixing block 57 and the second fixing block 58 are unlocked. Then, the toothed frame 55 drives the first gear 53 and the second gear 54 to rotate, so that the pressure plate 52 unfolds. Then, the fixing plate 51 is controlled to rotate to clamp and fix the tree. The toothed frame 55 is released so that the pressure plate 52 cooperates with the fixing plate 51 to clamp and stabilize the tree, achieving the effect of making it convenient for the operator to operate the fluorescence spectrometer 2 in a standing position outdoors.

[0034] like Figure 1 and Figure 5As shown, the support mechanism 6 includes a first fixing member 61, a first support plate 62, a first fixing frame 63, a second spring 64, a blocking member 65, and a torsion spring 66. The first fixing member 61 is connected to the right side of both the front and rear parts of the first protective frame 1. The first support plate 62 is rotatably connected between the first fixing members 61. The first support plate 62 is used to support and clamp the tree. The first fixing frame 63 is bolted to the upper right side of the first protective frame 1. The blocking member 65 is slidably connected to both the front and rear parts of the first fixing frame 63. The blocking member 65 is used to block and limit the first support plate 62. The top of the blocking member 65 is an arc-shaped structure, which makes it easy for the blocking member 65 to be pushed. The blocking member 65 can be pushed by the adjacent fixing plate 51. The second spring 64 is connected between the blocking member 65 and the first fixing frame 63. The torsion spring 66 is connected between the first support plate 62 and the adjacent first fixing member 61.

[0035] It should be noted that the method of fixing the tree using the fixing plate 51 and the pressure plate 52 may be unstable. Therefore, when the fixing plate 51 is rotated 180 degrees, the fixing plate 51 will push the adjacent blocking member 65 to slide. As the blocking members 65 slide towards each other, the second spring 64 will be compressed. At this time, the blocking members 65 no longer block or limit the first support plate 62. In the initial state, the torsion spring 66 is in a state of deformation. Under the action of the torsion spring 66, the first support plate 62 will rotate 90 degrees to the right, thereby contacting the tree and improving the support stability of the device. In summary, by rotating the fixing plate 51, the blocking members 65 are pushed, thereby contacting the locked state of the first support plate 62. Then, the first support plate 62 automatically rotates under the action of the torsion spring 66, thereby supporting the device and improving the support stability of the device.

[0036] like Figure 1 and Figure 6As shown, it also includes a lifting mechanism 7, which includes a second fixing member 71, a first sliding member 72, a second support plate 73, a drive motor 74, a pulley assembly 75, a lead screw 76, and a connecting rod 77. The first fixing member 61 is connected to the bottom right side of the first protective frame 1. The lead screw 76 is rotatably connected to the front and rear sides of the bottom of the first protective frame 1. The lead screw 76 is threadedly connected to the first sliding member 72. The first sliding member 72 is slidably connected to the first protective frame 1. The second fixing member 71 and the first sliding member 72 are rotatably connected to each other. A connecting rod 77 is connected, and adjacent connecting rods 77 are rotatably connected. A second support plate 73 is slidably connected between the tops of the connecting rods 77. The second support plate 73 is used to support the fluorescence spectrometer 2. A drive motor 74 is bolted to the bottom left side of the first protective frame 1. A pulley assembly 75 is connected between the output shaft of the drive motor 74 and the lead screw 76. The pulley assembly 75 includes a pulley and a transmission belt. The output shaft of the drive motor 74 and the left side of the lead screw 76 are both connected to pulleys. A transmission belt is wound between adjacent pulleys.

[0037] It should be noted that, to improve ease of use, when the operator uses the fluorescence spectrometer 2, the drive motor 74 can be directly started. The output shaft of the drive motor 74 drives the pulley assembly 75 to rotate, which in turn causes the lead screw 76 to rotate. The rotation of the lead screw 76 causes the first sliding member 72 to slide to the right, which in turn causes the connecting rod 77 to rotate and retract. As the connecting rod 77 rotates and retracts, it pushes the second support plate 73 to move upward, thus pushing the fluorescence spectrometer 2 upward and raising it for easy operation. In summary, by driving the pulley assembly 75 through the output shaft of the drive motor 74, the lead screw 76 rotates. As the lead screw 76 rotates, the first sliding member 72 moves closer to the first fixed member 61, causing the connecting rod 77 to rotate and retract, which in turn pushes the second support plate 73 upward, achieving the effect of automatically raising the position of the fluorescence spectrometer 2, making it easier for the operator to quickly operate and use the fluorescence spectrometer 2.

[0038] like Figure 1 and Figure 7 As shown, it also includes a limiting mechanism 8, which includes a connecting member 81, a second sliding member 82, a limiting member 83, and a third spring 84. The first sliding members 72 are connected to the connecting member 81 on the side away from each other, and the second sliding members 82 are connected to the right side of the connecting member 81. The second sliding members 82 are used to limit and lock the first support plate 62. The first protective frame 1 is welded with limiting members 83 on both the front and rear sides. The limiting members 83 are used to limit the adjacent second sliding members 82. The second sliding members 82 are slidably connected to the adjacent limiting members 83. The third spring 84 is connected between the second sliding members 82 and the adjacent limiting members 83.

[0039] It should be noted that, in order to prevent the first support plate 62 from accidentally rotating and resetting, as the first sliding member 72 begins to slide to the right, it will drive the connecting member 81 to move to the right, thereby causing the second sliding member 82 to slide to the right. The third spring 84 will be compressed. When the second sliding member 82 slides to the right to its limit position, the second sliding member 82 will be located on the upper side of the first support plate 62, thereby limiting the first support plate 62 and preventing it from accidentally flipping and resetting. In summary, by driving the connecting member 81 to move to the right through the first sliding member 72, the second sliding member 82 slides to the right, thereby limiting and locking the first support plate 62 after it has been flipped and unfolded, preventing the first support plate 62 from accidentally flipping and resetting.

[0040] like Figure 1 and Figure 8 As shown, it also includes a locking mechanism 9, which includes a third fixing member 91 and a locking member 92. The top of the fixing frame 56 is connected to the third fixing member 91, and the top of the toothed frame 55 is opened with a locking groove 93. The locking member 92 is rotatably connected to the third fixing member 91. The locking member 92 is used to engage with the locking groove 93. The right end of the locking member 92 is a hook-shaped structure, which can better engage with the locking groove 93.

[0041] It should be noted that when the operator slides the toothed frame 55, the clip 92 can be engaged with the locking groove 93, thus avoiding the need for the operator to continuously fix the toothed frame 55, which would increase the difficulty of operation. When the toothed frame 55 needs to be operated later, the clip 92 can be rotated to disengage the clip 92 from the locking groove 93. In summary, by engaging the clip 92 with the locking groove 93, the toothed frame 55 can be locked and fixed after sliding to the left, avoiding the need for the operator to continuously fix the toothed frame 55.

[0042] like Figure 1 and Figure 9 As shown, it also includes a placement mechanism 10, which includes a second fixed frame 101 and a placement rack 102. The second fixed frame 101 is welded to the front side of the first protective frame 1, and the placement rack 102 is slidably connected to the second fixed frame 101. The placement rack 102 is used to place the test tube.

[0043] It should be noted that the placement rack 102 can be pulled forward and slid out to place the collected sample tubes on the placement rack 102. When using the fluorescence spectrometer 2, the sample tubes on the placement rack 102 can be directly taken out for testing, avoiding the sample tubes being difficult to place, which may cause damage or loss of the sample tubes.

[0044] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the invention without departing from the principles and spirit of the invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for illustrative purposes only and is not intended to limit the invention; rather, the scope of protection is defined by the content of the claims.
