Description

Technical Field

[0001] This utility model relates to the field of observation instrument technology, specifically to an observation device for ICP-MS to capture cone-shaped apertures. Background Technology

[0002] ICP-MS, or Inductively Coupled Plasma Mass Spectrometer, has a sampling cone and a cutoff cone that are key components of the instrument's sample introduction system. These components are responsible for extracting the ion flow from the high-temperature plasma and transmitting it to the mass spectrometer. During use, the cutoff cone has a very small diameter, and the cone hole is very easy to be blocked or deposited by the sample matrix, salts, particles, etc., so it needs to be frequently removed from the main unit for cleaning.

[0003] Existing methods for cleaning conical bores typically involve using pointed cotton swabs dipped in dilute acid. However, due to the small diameter of the swabs, it is difficult to directly and clearly observe the blockage, corrosion, or deposits inside the bore with the naked eye. After cleaning, it is difficult to quickly and intuitively confirm the cleaning effect, especially the cleanliness inside the bore. It is necessary to reinstall the instrument for testing, and if the effect is not satisfactory, the disassembly and cleaning process must be repeated. While a microscope can be used, the cone is held by hand and positioned under the microscope. The bore is a deep hole, which has poor stability and makes it difficult to evenly illuminate the inner wall of the hole. It is easy to produce shadows or reflections, resulting in unclear observation and low observation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an observation device for ICP-MS to capture cone-shaped holes, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An observation device for ICP-MS interception of cone-shaped holes includes a support rod mounted on a base, an electric telescopic rod mounted on one side of the top of the base, a microscope head mounted on the upper outer ring of the support rod by fixing bolts, and an observation component provided at the end of the push rod of the electric telescopic rod.

[0007] The observation assembly includes a support rotating seat and a support cylinder. The support rotating seat is slidably mounted on the outer ring of the support rod, and the bottom end of the support rotating seat is connected to the end of the push rod of the first electric telescopic rod. The support cylinder is rotatably mounted on the end of the support rotating seat away from the support rod. A ball joint is movably mounted on the top of the support cylinder, and a support plate is fixedly mounted on the top of the ball joint. A positioning block is provided at the front position of the top of the support plate, and an electric telescopic rod is installed at the rear position of the top of the support plate. A fixing plate that adapts to the positioning block is installed at the end of the push rod of the second electric telescopic rod. A cutting cone body is provided between the positioning block and the fixing plate.

[0008] Preferably, the lower part of the microscope head is provided with a light ring composed of several LED beads, and the center points of the microscope head, the cutting cone body, and the support rotating base are on the same vertical line.

[0009] Preferably, a locking knob is threaded through the front end of the support rotating seat, one end of the locking knob extending into the support rotating seat abuts against the outer ring of the support cylinder, and a turntable is provided at the lower position of the outer ring of the support cylinder.

[0010] Preferably, a clamping screw is threaded through the bottom end of the support cylinder, and a clamping plate is fixedly connected to the top end of the clamping screw.

[0011] Preferably, the bottom end of the clamping screw is provided with a rotating handle, and the clamping plate and the ball head rod are slidably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up an observation component in conjunction with the truncated cone body, allows for quick clamping of the truncated cone body during observation and cleaning. The support plate is positioned directly below the microscope head, and the electric telescopic rod works in conjunction with the positioning block for positioning and clamping, so that the microscope head is aligned with the cone hole of the truncated cone body. At the same time, it eliminates the need for long-term manual cleaning, thus eliminating the risk of accidental collisions or drops caused by hand operation and reducing the labor intensity of personnel.

[0015] The support rotating base, support cylinder, locking knob, turntable, positioning block, and clamping plate work together to adjust the tilt angle of the truncated cone body during observation. At the same time, the truncated cone body can rotate around its own axis, which is convenient for observing different positions of the hole wall. A ring light is set below the microscope head to provide uniform and shadow-free illumination. The support height of the truncated cone body can be adjusted by the cooperation of the electric telescopic rod, support rod, and support rotating base. Attached Figure Description

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.

[0022] Example 1

[0023] Combination Figures 1-4 An observation device for ICP-MS to capture cone-shaped holes includes a support rod 1 mounted on a base, an electric telescopic rod 2 mounted on one side of the top of the base, a microscope head 3 mounted on the upper outer ring of the support rod 1 by fixing bolts, and an observation component 4 provided at the end of the push rod of the electric telescopic rod 2.

[0024] See Figure 2 and Figure 3 Furthermore, the observation component 4 has a support rotating seat 5 and a support cylinder 6. The support rotating seat 5 is slidably installed on the outer ring of the support rod 1, and the bottom end of the support rotating seat 5 is connected to the end of the push rod of the electric telescopic rod 2. The support cylinder 6 is rotatably installed on the end of the support rotating seat 5 away from the support rod 1. A ball head rod 7 is movably installed on the top of the support cylinder 6, and a support plate 8 is fixedly installed on the top of the ball head rod 7. A positioning block 9 is set at the front position of the top of the support plate 8, and an electric telescopic rod 11 is installed at the rear position of the top of the support plate 8. The end of the push rod of the second 11 is equipped with a fixing plate that is compatible with the positioning block 9. The cutting cone body 10 is set between the positioning block 9 and the fixing plate. The lower part of the microscope head 3 is equipped with a light ring composed of several LED beads. The center points of the microscope head 3, the cutting cone body 10 and the support rotating seat 5 are on the same vertical line. The front end of the support rotating seat 5 is threaded with a locking knob 12. One end of the locking knob 12 extends into the support rotating seat 5 and abuts against the outer ring of the support cylinder 6. A turntable 13 is set at the lower position of the outer ring of the support cylinder 6.

[0025] Specifically, during testing, the severing cone body 10 can be placed on the top surface of the support plate 8 as needed. Then, the electric telescopic rod 11 can be activated to push the fixing plate to clamp the severing cone body 10 and complete the fixation. At this time, the support plate 8 is directly below the microscope head 3. The cone hole of the severing cone body 10 can be observed through the microscope head 3 according to existing technology. A pointed cotton swab dipped in dilute acid is used to clean it so as to remove the sample matrix, salt, particulate matter and other blockages adhering to it. The process does not require personnel to clean it by hand, so as to clean the alignment and reduce the risk of falling. During cleaning, since the support cylinder 6 is rotatably installed on the support rotating seat 5 and the support cylinder 6 is locked and fixed by the locking knob 12, the locking knob 12 can be loosened. Then, the personnel can hold the turntable 13 and rotate the support cylinder 6, thereby driving the severing cone body 10 to rotate to observe different positions of the hole wall.

[0026] Example 2

[0027] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the bottom end of the support cylinder 6 is threaded with a clamping screw 14, the top end of the clamping screw 14 is fixedly connected with a clamping plate 15, the bottom end of the clamping screw 14 is provided with a rotating handle, the clamping plate 15 is slidably connected to the ball head rod 7, the lower part of the outer ring of the ball head rod 7 is provided with anti-slip texture, the clamping plate 15 is semi-circular, and the top surface of the clamping plate 15 is in contact with the top surface of the ball head rod 7.

[0028] Specifically, by activating the electric telescopic rod 2, the support rotating seat 5 can be pushed to slide on the support rod 1 to adjust the observation height of the intercepting cone body 10. By turning the clamping screw 14 away from the ball head rod 7, the clamping plate 15 can be moved away from the ball head rod 7, thus releasing the clamping of the ball head rod 7. Then, the ball head rod 7 can be adjusted by tilting it to optimize the internal illumination of the cone hole of the intercepting cone body 10 and improve the observation depth.

[0029] In actual operation, during testing, the truncated cone body 10 can be placed on the top surface of the support plate 8 as needed. Then, the electric telescopic rod 11 can be activated to push the fixing plate to clamp the truncated cone body 10 to complete the fixation. At this time, the support plate 8 is directly below the microscope head 3. The cone hole of the truncated cone body 10 can be observed through the microscope head 3 according to the existing technology. The cone body 10 can be cleaned with a pointed cotton swab dipped in dilute acid to remove the sample matrix, salt, particulate matter and other blockages adhering to it. The process does not require manual cleaning, which is convenient for cleaning and reduces the risk of falling.

[0030] Furthermore, during cleaning, since the support cylinder 6 is rotatably mounted on the support rotating seat 5, and the support cylinder 6 is locked and fixed by the locking knob 12, the locking knob 12 can be loosened. Then, the personnel can hold the turntable 13 and rotate the support cylinder 6, thereby driving the cutting cone body 10 to rotate, so as to observe different positions of the hole wall.

[0031] By activating the electric telescopic rod 2, the support rotating seat 5 can be pushed to slide on the support rod 1 to adjust the observation height of the intercepting cone body 10. By turning the clamping screw 14 away from the ball head rod 7, the clamping plate 15 can be moved away from the ball head rod 7, thus releasing the clamping of the ball head rod 7. Then, the ball head rod 7 can be adjusted by tilting it to optimize the internal illumination of the cone hole of the intercepting cone body 10 and improve the observation depth.

[0032] Furthermore, the display and control components and modules used in the aforementioned electric telescopic rod 1 2, microscope lens 3, and electric telescopic rod 2 11 are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
