Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a sample placement bracket suitable for a microscopic enhanced Raman testing platform. Background Art

[0002] Raman testing utilizes Raman spectroscopy to analyze molecular structure. Raman testing is based on the phenomenon of Raman scattering, an inelastic scattering spectroscopy technique. When laser light strikes a sample, the laser photons interact with the molecules within the sample, generating scattered light. A portion of this scattered light is Raman scattered light, which is closely related to the sample's molecular structure. Analysis and interpretation of Raman scattered light can reveal the sample's molecular structure and chemical information. Raman spectroscopy can reveal characteristic information about a substance's inherent structure, vibrational state, and composition, and is therefore widely used in fields such as basic research and materials identification.

[0003] A simple microscope-assisted working platform is disclosed in the Chinese utility model patent with the announcement number CN219202046U. When used with a simple microscope, this device can adjust the position and detection brightness of the inspected product as needed to adapt to different inspection requirements. It has high adjustment accuracy and is more convenient for users to use.

[0004] However, in actual use, the device can only place and fix one glass slide with a test sample on the test table. After the test is completed, it needs to be released and the next glass slide with a sample needs to be placed and fixed. This makes the operation more troublesome and reduces the detection efficiency of the sample.

[0005] In summary, there is currently a need for a sample placement bracket that can clamp multiple groups of glass slides simultaneously. Utility Model Content

[0006] The utility model aims to provide a sample placement bracket suitable for a microscopic enhanced Raman testing platform. The device drives a movable clamping plate to move closer to a fixed clamping plate by rotating a screw rod, so that multiple groups of glass slides can be clamped at the same time.

[0007] The technical solution adopted by the present invention to solve the above problems is: a sample placement bracket suitable for a micro-enhanced Raman testing platform, comprising:

[0008] A testing platform, the top of which is provided with a hollow groove, and both ends of the testing platform are equipped with buckles;

[0009] The movable detection component includes a bracket movably connected to the top of the detection platform, a glass slide is placed at intervals on the top of the bracket, a fixed plate is fixedly connected to one side of the top of the detection platform, a sliding rod is slidably connected to the fixed plate, one end of the sliding rod is fixedly connected to the pressure plate, and the sliding rod is also fixedly connected to the connecting plate, the outer sleeve of the sliding rod is provided with a first spring, and a connecting rod is hinged between the connecting plate and the bracket through a hinge, a fixed block is provided on the bracket and the fixed block is fixedly connected to the top of the detection platform, a pin rod is slidably connected to the fixed block, the outer sleeve of the pin rod is provided with a second spring, and pin holes are provided at intervals on the bracket.

[0010] A further preferred technical solution is that a fixed splint is fixedly connected to one side of the top of the bracket, a movable splint is also provided on the top of the bracket, and a mounting plate is also fixedly connected to the top of the bracket, a screw rod is threadedly connected to the mounting plate, and the screw rod and the movable splint are rotatably connected.

[0011] A further preferred technical solution is that positioning grooves are provided on the fixing splint at intervals.

[0012] A further preferred technical solution is that: a guide rod is fixedly connected to the movable splint and the guide rod is slidably connected to the mounting plate.

[0013] A further preferred technical solution is that: a guide block is fixedly connected to the bottom of the bracket, and a guide groove is provided on the top of the detection platform and is slidably connected to the guide block.

[0014] A further preferred technical solution is that rectangular through slots are provided at intervals on the bracket.

[0015] A further preferred technical solution is that: both ends of the first spring are fixedly connected to the fixing plate and the pressure plate respectively.

[0016] A further preferred technical solution is that: both ends of the second spring are fixedly connected to the fixing block and the circular protrusion at the end of the pin rod respectively.

[0017] A further preferred technical solution is that two groups of sliding rods are provided, both of which are slidably connected to the fixed plate.

[0018] A further preferred technical solution is that a flexible protective pad is provided on one side of the movable splint.

[0019] In summary, the present invention has the following advantages:

[0020] 1. The utility model drives the movable clamping plate to move closer to the fixed clamping plate by rotating the screw rod, so that multiple groups of glass slides can be clamped at the same time. The operation is simple, convenient and fast, and the detection efficiency of the samples is effectively improved.

[0021] 2. The present invention facilitates accurate placement of the glass slide by providing the positioning groove, thereby preventing the sample on the glass slide from deviating from the microscope lens during detection.

[0022] 3. The utility model drives the connecting plate to move by pushing the pressure plate, and with the hinged action between the connecting plate and the bracket and the connecting rod, and the sliding cooperation between the guide block and the guide groove, the bracket can be pushed, thereby facilitating the replacement of the glass slide with the sample, further improving the detection efficiency of the sample. At the same time, when the lower group of glass slides moves to the bottom of the microscope head, under the rebound action of the second spring, the pin rod will automatically insert into the pin hole to limit the bracket, thereby ensuring the accuracy of the movement of the glass slide.

[0023] 4. After the detection is completed, the present invention pulls the pin rod to disengage it from the pin hole and slowly releases the pressure plate. During this process, the rebound effect of the first spring is utilized to make the pressure plate automatically reset continuously, thereby driving the bracket to automatically reset so that the glass slide can be removed, further improving the practicality of the device.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0031] Example:

[0032] Please combine Figure 1-4 , a sample placement bracket suitable for a micro-enhanced Raman testing platform of this embodiment includes:

[0033] Testing platform 1, the size of the testing platform 1 is 22.5×23.5cm, the top of the testing platform 1 is provided with a hollow groove 2, and buckles 3 are installed at both ends of the testing platform 1. The size of the hollow groove is 11.5×11.5cm, and the testing platform 1 can be fixed on the existing platform through the buckles 3;

[0034] The mobile detection component includes a bracket 101 movably connected to the top of the detection platform 1, and a glass slide 102 is equidistantly placed on the top of the bracket 101. The size of the glass slide 102 is 7.5×2.5 cm. A fixed plate 103 is fixedly connected to one side of the top of the detection platform 1. Two groups of slide rods 104 are symmetrically slidably connected to the fixed plate 103. One end of the two groups of slide rods 104 is fixedly connected to the same pressure plate 105, and the other end of the two groups of slide rods 104 is fixedly connected to the same connecting plate 106. The outer sleeve of the slide rod 104 is provided with a first spring 107. The two ends of the first spring 107 are fixedly connected to the fixed plate 103 and the pressure plate 105 respectively. A connecting rod 108 is hinged between the connecting plate 106 and the bracket 101 through a hinge. A fixed block 109 is provided on the right side and the fixed block 109 is fixedly connected to the top of the detection platform 1. A pin rod 110 is slidably connected to the fixed block 109. A second spring 111 is sleeved on the outside of the pin rod 110. The two ends of the second spring 111 are respectively fixedly connected to the fixed block 109 and the circular protrusion at the end of the pin rod 110. Pin holes 112 are equidistantly provided on the right side of the bracket 101. Guide blocks 9 are symmetrically fixedly connected on both sides of the bottom of the bracket 101. Guide grooves are symmetrically provided on the top of the detection platform 1 and are slidably connected to the guide blocks 9, which can play a certain guiding role in the forward and backward movement of the bracket 101. Rectangular through grooves are equidistantly provided on the bracket 101 to prevent obstruction of the lighting light. The diameter of the pin hole 112 matches the diameter of the pin rod 110.

[0035] A fixed splint 4 is fixedly connected to one side of the top of the bracket 101, and a movable splint 5 is provided on the other side of the top of the bracket 101. The top of the bracket 101 is also fixedly connected to a mounting plate, and a screw rod 6 is threadedly connected to the mounting plate and the screw rod 6 is rotatably connected to the movable splint 5, which is convenient for clamping and fixing multiple groups of glass slides 102 at the same time. Positioning grooves 7 are equidistantly provided on the fixed splint 4, which is convenient for precise placement of the glass slide 102, thereby avoiding the situation where the sample in the glass slide 102 deviates from the microscope lens during detection. Guide rods 8 are symmetrically fixedly connected to the movable splint 5 and the guide rods 8 are slidably connected to the mounting plate, which can play a certain guiding role in the horizontal movement of the movable splint 5.

[0036] The implementation principle of a sample placement bracket suitable for a microscopic enhanced Raman test platform in an embodiment of the present application is as follows: before use, the detection platform 1 is fixedly connected to the inside of the Raman test platform. The Raman test platform is a box structure design with an open front end. The internal space of the Raman test platform is 49-90 cm long, 37 cm high, and 42 cm deep. First, one end of the glass slide 102 is placed in the positioning groove 7 in sequence, and then the screw rod 6 is rotated. At this time, the movable splint 5 can be driven to approach the fixed splint 4 to clamp and fix multiple groups of glass slides 102 at the same time, and then the lighting lamp 2 is turned on to increase the brightness during detection to detect the samples in the glass slide 102.

[0037] After the inspection of the sample in the current glass slide 102 is completed, the pressure plate 105 is pressed, and the connecting plate 106 is moved by pushing the pressure plate 105. The hinged connection between the connecting plate 106 and the bracket 101 and the connecting rod 108, and the sliding cooperation between the guide block 9 and the guide groove enable the bracket 101 to be pushed, thereby facilitating the replacement of the glass slide 102 with the sample. At the same time, when the lower group of glass slides 102 moves to the top center of the detection table 1, under the rebound action of the second spring 111, the pin rod 110 will automatically be inserted into the pin hole 112 to limit the bracket 101, thereby ensuring the accuracy of the movement of the glass slide 102. When replacing the glass slide 102 again, it is only necessary to pull out the pin rod 110 and continue to push the pressure plate 105. Repeat this operation until all samples in the glass slides 102 are inspected.

[0038] After the detection is completed, the pin rod 110 is pulled out of the pin hole 112, and at the same time, the pressure plate 105 is slowly released. During this process, the rebound effect of the first spring 107 is used to make the pressure plate 105 automatically reset continuously, thereby driving the bracket 101 to automatically reset so that the glass slide 102 can be removed.

[0039] In addition, a further improvement is that a flexible protective pad is provided on one side of the movable clamping plate 5, which can provide a certain degree of protection for the glass slide 102 and prevent it from being compressed and damaged when being clamped and fixed.

[0040] In addition, the same or similar reference numerals are used whenever possible in the drawings and description to refer to the same or similar parts or steps. The drawings are presented in simplified form and are not drawn to exact scale. For convenience and clarity only, directional terms such as top, bottom, front, rear, left, right, front, back, upward, above, above, below, below, rear, and front may be used with respect to the drawings.
