Description

Technical Field

[0001] This utility model relates to the technical field of grating blade clamping structure, specifically to a grating blade clamping structure with anti-loosening function. Background Technology

[0002] A grating blade is part of an optical element consisting of a large number of parallel slits, or gratings, of equal width and spacing; these slits can be transparent or opaque; in a grating, the arrangement and shape of the blades play a key role in the diffraction and interference effects of light.

[0003] To ensure the stable operation of grating blades in optical system equipment such as small spectrometers, springs and clamps are typically used to clamp the grating blades onto a suitable mounting base. Existing small spectrometers need to detect and analyze light of different wavelengths, so the grating blades need to be moved to change the relative angle between the incident light and the grating, so that light of different wavelengths is focused onto different positions of the detector according to the principle of diffraction, thereby achieving scanning of different wavelength ranges.

[0004] Then, the grating blades will vibrate during movement. Because the spring has elasticity, the clamping block can easily shift on the grating blades, thus affecting the clamping effect on the grating blades.

[0005] Based on this, the present invention designs a grating blade clamping structure with anti-loosening function to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a grating blade clamping structure with anti-loosening function.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A grating blade clamping structure with anti-loosening function includes a mounting base, an mounting frame slidably connected to the inner wall of the mounting base, two rubber frames slidably connected to the inner wall of the mounting frame, springs fixedly connected to the opposite ends of the rubber frames and the mounting frame, and an anti-loosening mechanism. The anti-loosening mechanism includes an iron frame fixedly connected to the end of the rubber frame, a rotating rod rotatably connected to the lower surface of one of the rubber frames, the surface of the rotating rod penetrating and extending to the inner wall of the iron frame, a magnet fixedly connected to the lower surface of the rotating rod, a rubber block fixedly connected to the bottom of one of the iron frames, and a blocking block slidably connected to both the upper and lower ends of the inner wall of the mounting frame.

[0009] Furthermore, a locking rod is slidably connected to the inner wall of the rotating rod, and the surface of the locking rod is slidably connected to the lower end of the surface of one of the rubber frames.

[0010] Furthermore, a spring is fixedly connected to the front end of the block, and the other end of the spring is fixedly connected to the inner wall of the mounting frame.

[0011] Furthermore, the inner wall of the mounting frame is fixedly connected with two anti-slip pads.

[0012] Furthermore, a guide frame is fixedly connected to one side of the mounting frame, and the guide frame is in the shape of a square trumpet.

[0013] Furthermore, the inner wall of the guide frame is fixedly connected with two guide blocks.

[0014] Furthermore, the surface of the guide block is rolled with rubber balls.

[0015] Furthermore, a stop bar is fixedly connected to the top of one of the rubber frames, and the upper surface of the rotating rod contacts the surface of the stop bar.

[0016] Furthermore, a driven block is fixedly connected to the lower end of the surface of the lever, and the surface of the driven block extends through and into the inner wall of one of the rubber frames.

[0017] Furthermore, a pull rope is fixedly connected to the front end of the blocking block, and the other end of the pull rope passes through the spring piece and the mounting frame in sequence and is fixedly connected to the pull block.

[0018] Beneficial effects

[0019] 1. By using a rotating rod, a magnet, an iron frame, and a rubber block, the two rubber frames are locked together, thereby increasing the resistance to the longitudinal movement of the rubber frames. This allows the two rubber frames to initially and stably contact the ends of the grating blades. The blocking block further locks the longitudinal movement of the rubber frames. Compared to existing methods where the clamping block may shift on the grating blades during movement, this method ensures that the rubber frames are firmly in contact with the ends of the grating blades by locking the rubber frames, thus guaranteeing the clamping effect on the grating blades.

[0020] 2. The spring clips ensure that the stop block is stably pressed against the end of the rubber frame, and the anti-slip pads increase the friction of the grating blades within the mounting frame, thereby ensuring that the grating blades are stably clamped within the mounting frame.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-4 A grating blade clamping structure with anti-loosening function includes a mounting base 1, a mounting frame 2 slidably connected to the inner wall of the mounting base 1, two rubber frames 3 slidably connected to the inner wall of the mounting frame 2, a spring 4 fixedly connected to the opposite end of the rubber frame 3 and the mounting frame 2, and an anti-loosening mechanism 5. The anti-loosening mechanism 5 includes an iron frame 51 fixedly connected to the end of the rubber frame 3, a rotating rod 53 rotatably connected to the lower end of the surface of one of the rubber frames 3, the surface of the rotating rod 53 penetrating and extending to the inner wall of the iron frame 51, a magnet 54 fixedly connected to the lower end of the surface of the rotating rod 53, a rubber block 55 fixedly connected to the bottom of one of the iron frames 51, and a blocking block 59 slidably connected to the upper end and the lower end of the inner wall of the mounting frame 2.

[0031] An electric push rod is fixedly connected to the inner wall of the mounting base 1, and the telescopic end of the electric push rod is fixedly connected to one side of the mounting frame 2.

[0032] In this embodiment of the invention, the grating blade is inserted into the mounting frame 2. At this time, the elastic force of the spring 4 pushes the rubber frame 3 to move and abut against the end of the grating blade, thereby causing the ends of the two iron frames 51 to abut against each other. The rotating rod 53 and the magnet 54 slide into the lower part of one of the iron frames 51 through the reserved hole on it, and the rubber block 55 slides into the inner wall of one of the iron frames 51, thereby sealing the reserved hole on one of the iron frames 51. At this time, the rotating rod 53 is rotated, causing the magnet 54 to rotate and abut against the end of one of the iron frames 51, pushing the stop block 59, so that the end of the stop block 59 abuts against the end of the rubber frame 3, thereby locking the rubber frame 3, so that the two rubber frames 3 are stably abutting against the end of the grating blade. At this time, the mounting base 1 is installed in a suitable position on the small spectrometer by bolts to ensure that the position and angle of the grating blade are accurately aligned.

[0033] When a small spectrometer is needed, it is usually equipped with a suitable light source, such as a xenon lamp or LED lamp. Different light sources are selected according to different application requirements. After the light emitted from the light source is guided and shaped by a series of optical elements such as lenses and mirrors, precise control of the incident angle of the light is crucial to the performance of the spectrometer. Generally, the position and angle of the light source and optical elements are adjusted so that the light shines on the grating blades at the optimal incident angle to obtain the maximum diffraction efficiency and the best spectral resolution. When the light shines on the grating blades, the grating blades use the principle of light diffraction to decompose polychromatic light into monochromatic light, so that light of different wavelengths can be analyzed and measured. Due to the periodic structure of the grating, the light undergoes diffraction... According to the grating equation, light of different wavelengths will be emitted at different diffraction angles, thus achieving spectral separation of polychromatic light. After the grating blades separate the spectrum, light of different wavelengths will be projected onto the detector inside the spectrometer. The detector is usually a linear array detector such as CCD or CMOS, which can detect light signals of multiple wavelengths simultaneously. The detector converts the received light signals into electrical signals, and then processes them through circuits such as amplification and filtering. The processed signals are transmitted to the spectrometer's control system for further analysis and calculation, and finally, spectral data is obtained. By analyzing the spectral data, information such as the chemical composition and physical properties of the sample can be obtained, thereby realizing qualitative and quantitative analysis of the sample.

[0034] In this embodiment of the invention, the two rubber frames 3 are mutually locked by the rotating rod 53, the magnet 54, the iron frame 51, and the rubber block 55, thereby increasing the resistance to the longitudinal movement of the rubber frames 3. This allows the two rubber frames 3 to initially and stably abut against the end of the grating blade. The blocking block 59 locks the longitudinal movement of the rubber frames 3. Compared with the existing method where the clamping block is prone to shifting on the grating blade during movement, this method ensures that the rubber frames 3 are stably abut against the end of the grating blade by locking the rubber frames 3, thus ensuring the clamping effect on the grating blade.

[0035] In some embodiments, such as Figure 2 and Figure 4 As shown, in a preferred embodiment of this utility model, a locking rod 56 is slidably connected to the inner wall of the rotating rod 53. The surface of the locking rod 56 is slidably connected to the lower end of the surface of one of the rubber frames 3. A spring piece 510 is fixedly connected to the front end of the blocking block 59. The other end of the spring piece 510 is fixedly connected to the inner wall of the mounting frame 2. Two anti-slip pads 515 are fixedly connected to the inner wall of the mounting frame 2. A stop bar 58 is fixedly connected to the top of one of the rubber frames 3. The upper surface of the rotating rod 53 contacts the surface of the stop bar 58. A driven block 57 is fixedly connected to the lower end of the surface of the locking rod 56. The surface of the driven block 57 penetrates and extends to the inner wall of one of the rubber frames 3. A pull rope 511 is fixedly connected to the front end of the blocking block 59. The other end of the pull rope 511 passes through the spring piece 510 and the mounting frame 2 and is fixedly connected to a pull block 512. The anti-slip pads 515 are rubber components.

[0036] In this embodiment of the utility model, the elastic force of the spring 510 pushes the blocking block 59 to move within the mounting frame 2, so that the end of the blocking block 59 abuts against the end of the rubber frame 3.

[0037] In this embodiment of the utility model, the spring sheet 510 ensures that the blocking block 59 is stably abutting against the end of the rubber frame 3, and the anti-slip pad 515 increases the friction of the grating blade in the mounting frame 2, thereby ensuring that the grating blade is stably clamped in the mounting frame 2.

[0038] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, a guide frame 513 is fixedly connected to one side of the mounting frame 2. The guide frame 513 is square and trumpet-shaped. Two guide blocks 514 are fixedly connected to the inner wall of the guide frame 513. Rubber balls 52 are rolledly connected to the surface of the guide blocks 514.

[0039] In this embodiment of the utility model, the guide frame 513, which is square and trumpet-shaped, is used to initially guide the grating blades. The guide block 514 and the rubber ball 52 are used to accurately guide the grating blades located in the guide frame 513, so as to ensure that the grating blades can be quickly inserted into the mounting frame 2.

[0040] It should be noted that the mounting base 1, mounting frame 2, magnet 54, iron frame 51, electric push rod, etc. mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electric push rod can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
