Description

Technical Field

[0001] This utility model relates to the field of direct-reading spectrometer technology, specifically to an electrode holder for a direct-reading spectrometer. Background Technology

[0002] A photoelectric direct-reading spectrometer typically includes a light source, a sample chamber, a spectral dispersion element, and a photosensitive detector. The electrode holder is a support used in atomic emission spectroscopy to support and adjust the sample electrode and the counter electrode. Depending on the state of the sample, it can be divided into four types: ordinary electrode holder, horizontal electrode holder for powder samples, block sample electrode holder, and solution turntable electrode holder.

[0003] The prior art patent document with publication number CN208443724U provides an electrode holder for a photoelectric direct-reading spectrometer, including a support, a horizontal plate, mounting holes, and a supporting mechanism. This enhances the use of argon atmosphere in the electrode holder and solves the problem that the electrode holder of the original photoelectric direct-reading spectrometer cannot effectively clamp rod-shaped or sheet-shaped samples, thus improving practical performance. Because the pressure block has a hemispherical structure, there are four sets of pressure blocks, and the four sets of pressure blocks are of the same specification. The pressure blocks are connected to the inside of the horizontal plate by springs. This design improves the clamping ability of the electrode holder for samples of various specifications. Because the nozzle is connected to the connection hole through the conduit, a set of gas columns, a set of conduits, a set of nozzles, and a set of connection holes are matched. This design improves the effect of the argon atmosphere structure of the electrode holder.

[0004] Although the device has many beneficial effects, it still has the following problems: During use, it is not convenient to adjust the electrode angle and it is not convenient to adapt to different direct-reading spectrometer detection requirements; secondly, the support position is fixed during use and it is not convenient to move to the required position, which needs to be improved. In view of this, we propose an electrode holder for a direct-reading spectrometer. Summary of the Invention

[0022] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] This utility model provides an overall structural schematic diagram of an embodiment of the electrode holder for a direct-reading spectrometer, including: Please refer to Figures 1-5. An electrode holder for a direct-reading spectrometer according to this embodiment includes a mounting base 1. A moving component 2 is fixed to the side wall of the mounting base 1. A frame 3 is welded to the top of the moving component 2. An adjusting component 4 is rotatably connected to one end of the frame 3. The adjusting component 4 includes a groove 401 formed in the side wall of one end of the frame 3. A connecting shaft 402 is rotatably connected to the side wall of the groove 401. A gear 403 is fixed to the outer circumference of the connecting shaft 402. A moving rod 404 is slidably connected to the bottom of the groove 401. A locking block 405 is fixed to the top of the moving rod 404. A spring 406, sleeved on the outer circumference of the moving rod 404, is fixed to the bottom of the locking block 405. A handle 407 is fixed to one end of the moving rod 404, which passes through the frame 3. An electrode clamp 5 is fixed to one end of the connecting shaft 402. By installing the sample electrode on the electrode clamp 5 and pulling the handle 407, the moving rod 404 moves downward, thereby moving the locking block 405 downward. Disengage from gear 403 and rotate electrode clamp 5 to the required angle to adapt to different needs. Electrode clamp 5 drives gear 403 on the outer circumference of connecting shaft 402 to rotate together. Release handle 407, and the rebound force of spring 406 drives the locking block 405 to move upward and engage gear 403, which is convenient for locking and improves stability.

[0024] It is worth noting that, in order to facilitate the movement of the electrode clamp 5, the moving component 2 specifically includes a motor 201. The output end of the motor 201 is fixedly provided with a lead screw 202 that is rotatably connected to the side wall of the mounting base 1. The outer circumference of the lead screw 202 is threadedly connected to a first slider 203. The top of the first slider 203 is fixedly provided with a base 204 located at the bottom of the frame 3. One end of the outer circumference of the lead screw 202 is fixedly provided with a clutch 205. The motor 201 is electrically connected to an external power source. By turning on the motor 201, the lead screw 202 is driven to rotate, thereby causing the first slider 203 to move the base 204, which in turn causes the frame 3 to move the electrode clamp 5 to the desired position. By controlling the clutch 205, the lead screw 202 can be locked, making the base 204 more stable.

[0025] Next, to prevent the mounting base 1 from shaking when moving, specifically, the bottom of the base 204 is fixed with a second slider 206 on both sides, and the top of the mounting base 1 is provided with a sliding groove 207 on both sides. The size and position of the second slider 206 match the size and position of the sliding groove 207. By using the second slider 206 that matches the size and position of the sliding groove 207, the movement of the mounting base 1 is made more stable.

[0026] Meanwhile, to improve stability, specifically, the size and position of gear 403 are matched with the size and position of locking block 405, and the height of moving rod 404 is greater than the height of locking block 405. The gear 403, which matches the size and position of locking block 405, facilitates improved locking stability, and the moving rod 404, which is greater than the height of locking block 405, facilitates the provision of space for the movement of locking block 405.

[0027] Furthermore, to prevent the connecting shaft 402 from detaching, specifically, a limiting groove 408 is provided inside the frame 3, and a limiting disk 409 is fixed at the other end of the connecting shaft 402. The limiting disk 409 rotates within the limiting groove 408 to facilitate limiting the connecting shaft 402.

[0028] It is worth noting that, in order to improve the stability of the electrode clamp 5, specifically, the diameter of the limiting disk 409 is larger than the diameter of the connecting shaft 402, and the size and position of the limiting groove 408 match the size and position of the limiting disk 409. By using the limiting disk 409, which matches the size and position of the limiting groove 408, the connecting shaft 402 is prevented from falling off.

[0029] Finally, in order to install the sample electrode, specifically, the electrode clamp 5 has multiple mounting grooves 6 on its side wall, and each mounting groove 6 has a limiting strip 7 fixed at the bottom of its inner circumference. The sample electrode is engaged through the mounting groove 6, and the limiting strip 7 prevents the sample electrode from slipping off.

[0030] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve any improvement to the internal structure and method. The device or equipment models mentioned in this article may be as follows: Motor 201: Y90S-2.

[0031] Referring to Figures 1-5, the electrode holder of a direct-reading spectrometer according to this embodiment is used in the following specific process: 1. According to the actual use, install the sample electrode in the mounting groove 6 on the side wall of the electrode clamp 5, pull the handle 407 to move the moving rod 404 downward, so that the locking block 405 disengages from the gear 403, rotate the electrode clamp 5 to the required angle, release the handle 407, and the rebound force of the spring 406 drives the locking block 405 to move upward and engage the gear 403 for locking, so that the sample electrode maintains a certain angle. 2: Start the motor 201 to make the lead screw 202 rotate and drive the first slider 203 to move, thereby causing the base 204 to drive the frame 3 to move, and then the electrode clamp 5 to drive the sample electrode to the required position, and control the clutch 205 to lock the lead screw 202.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
