Technical Field
[0001] The utility model relates to the technical field of ICP spectrometers, and particularly relates to a front and rear adjustment device for an ICP spectrometer torch tube. Background Art
[0002] An ICP spectrometer is an analytical instrument used in the field of materials science. After the sample is processed into a solution, it becomes a full sol by a super atomization device and is introduced into the tube from the bottom, and is sprayed into the plasma torch from the nozzle through the quartz torch tube at the axis. When the sample aerosol enters the plasma flame, most of it is immediately decomposed into excited atoms and ions. When these excited particles return to the stable ground state, they will release a certain amount of energy (manifested as a spectrum of a certain wavelength). By measuring the unique spectral lines and intensities of each element and comparing with the standard solution, the types and contents of the elements contained in the sample can be known.
[0003] Most of the existing quartz torch tubes of ICP spectrometers are in a fixed state and cannot be adjusted back and forth, so it is not convenient to accurately adjust the front and rear positions of the plasma flame to align with the optical path tube and the entrance slit. Content of the Utility Model
[0004] In order to solve the above problems, the utility model provides a front and rear adjustment device for an ICP spectrometer torch tube.
[0005] The above technical purpose of the utility model is achieved by the following technical solutions: A front and rear adjustment device for an ICP spectrometer torch tube includes a mounting plate horizontally arranged on a box body. The length direction of the mounting plate is perpendicular to the surface of the box body where the mounting plate is located. A first opening is provided along the length direction of the mounting plate on the mounting plate. A sliding plate is slidably arranged along the length direction of the mounting plate in the first opening. A driving component for driving the sliding plate to slide is arranged on the sliding plate. A second opening is provided along the length direction of the mounting plate on the sliding plate. Two clamping blocks are slidably arranged along the length direction of the mounting plate in the second opening. An adjusting component for adjusting the position of the clamping blocks is arranged on the sliding plate.
[0006] By adopting the above technical solutions, the mounting plate, the sliding plate, the driving component, the clamping blocks and the adjusting component are provided. By adjusting the position of the clamping blocks through the adjusting component, the two clamping blocks clamp the quartz torch tube, and the position of the quartz torch tube can be accurately adjusted to the center position of the working coil through adjusting the position of the clamping blocks, so that the working effect is better. Then, the driving component drives the sliding plate to slide to finely adjust the position of the quartz torch tube, and accurately adjust the front and rear positions of the plasma flame to align with the optical path tube and the entrance slit, so that the observation effect is better.
[0007] Further, the driving component includes a first threaded rod rotatably arranged on the sliding plate. The length direction of the first threaded rod is consistent with the length direction of the mounting plate. The mounting plate is in screw fit with the first threaded rod through a threaded hole. A first screwing cap is arranged at one end of the first threaded rod on the sliding plate.
[0008] By adopting the above technical solution, the first threaded rod and the first screwing cap are provided. Rotating the first screwing cap drives the first threaded rod to rotate. Since the mounting plate is in screw fit with the first threaded rod through the threaded hole, the first threaded rod moves back and forth relative to the mounting plate while rotating, driving the sliding plate to move back and forth, thereby adjusting the position of the sliding plate.
[0009] Further, the adjusting component includes second threaded rods spirally arranged on both sides of the sliding plate respectively. The two second threaded rods are concentrically arranged with the first threaded rod. One end of each second threaded rod is placed in the second opening and is provided with a second screwing cap. The second screwing cap abuts against the adjacent clamping block. A fixing unit for fixing the clamping block is further arranged on the mounting plate.
[0010] By adopting the above technical solution, the second threaded rods, the second screwing caps and the fixing unit are provided. Rotating the second screwing cap drives the second threaded rods to rotate, so that the second threaded rods and the second screwing caps move relative to the sliding plate, pushing the clamping blocks to move, adjusting the position of the quartz torch tube. After adjustment, the clamping blocks are fixed by the fixing unit, thus ensuring the stability of the quartz torch tube.
[0011] Further, the diameters of the first screwing cap and the second screwing cap are both larger than the thickness of the sliding plate.
[0012] By adopting the above technical solution, the diameters of the first screwing cap and the second screwing cap are set to be larger than the thickness of the sliding plate, so that the first screwing cap and the second screwing cap can be rotated from above or below the sliding plate, and the adjustment is more convenient.
[0013] Further, a contact rod is concentrically arranged on the side of the second screwing cap adjacent to the clamping block. The end of the contact rod abuts against the clamping block.
[0014] By adopting the above technical solution, a contact rod is concentrically arranged on the side of the second screwing cap adjacent to the clamping block. In order to avoid a large contact area when the second screwing cap directly contacts the clamping block, resulting in too large a frictional force, so that a large force is required to rotate the second screwing cap, the contact rod abuts against the clamping block, facilitating the rotation of the second screwing cap.
[0015] Further, the fixing unit includes two sliding rods vertically arranged at the bottom of the mounting plate. The two sliding rods are spaced along the length direction of the mounting plate. A pressing plate is slidably arranged on the two sliding rods together. A third threaded rod is vertically rotatably arranged at the bottom of the mounting plate between the two sliding rods. The pressing plate is in screw fit with the third threaded rod through a threaded hole. A locking plate is arranged at the edge of the clamping block, and the locking plate is located between the pressing plate and the mounting plate.
[0016] By adopting the above technical solution, the sliding rods, the pressing plate, the third threaded rod, and the locking plate are provided. By rotating the third threaded rod, the pressing plate moves towards the mounting plate, so that the locking plate is clamped between the mounting plate and the pressing plate, and the position of the clamping block is fixed.
[0017] Further, clamping grooves are respectively formed on the opposite surfaces of the two clamping blocks.
[0018] By adopting the above technical solution, the clamping grooves are formed on the opposite surfaces of the clamping blocks, so that the quartz torch tube is fixed more firmly.
[0019] In summary, the utility model has the following beneficial effects: In this application, the mounting plate, the sliding plate, the driving component, the clamping block, and the adjusting component are provided. By adjusting the position of the clamping block through the adjusting component, the two clamping blocks clamp the quartz torch tube, and the position of the quartz torch tube can be accurately adjusted to the center position of the working coil by adjusting the position of the clamping block, so that the working effect is better. Then, the driving component drives the sliding plate to slide, and the position of the quartz torch tube is finely adjusted, and the front and rear positions of the plasma flame are accurately adjusted to be aligned with the optical path cylinder and the incident slit, so that the observation effect is better.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0028] As Figures 1-6 shown, the embodiments of the present application disclose an ICP spectrometer torch tube front and rear adjustment device, including a mounting plate 10, a sliding plate 20, a driving assembly 30, a clamping block 22, and an adjusting assembly 40. The mounting plate 10 is horizontally arranged on the box body 1, and the length direction of the mounting plate 10 is perpendicular to the surface of the box body 1 where the mounting plate 10 is located. A first opening 11 is provided on the mounting plate 10 along the length direction of the mounting plate 10. The sliding plate 20 is slidably arranged in the first opening 11 along the length direction of the mounting plate 10. The driving assembly 30 is arranged on the sliding plate 20 for driving the sliding plate 20 to slide. A second opening 21 is provided on the sliding plate 20 along the length direction of the mounting plate 10. There are two clamping blocks 22, and the clamping blocks 22 are slidably arranged in the second opening 21 along the length direction of the mounting plate 10. The adjusting assembly 40 is arranged on the sliding plate 20 for adjusting the position of the clamping block 22. By adjusting the position of the clamping block 22 through the adjusting assembly 40, the quartz torch tube is clamped by the two clamping blocks 22, and by adjusting the position of the clamping block 22, the quartz torch tube can be accurately adjusted to the center position of the working coil, making the working effect better. Then, the driving assembly 30 drives the sliding plate 20 to slide to finely adjust the position of the quartz torch tube, and accurately adjusts the front and rear positions of the plasma flame to be aligned with the optical path tube and the incident slit, making the observation effect better.
[0029] Specifically, the driving component 30 includes a first threaded rod 31 rotatably arranged on the sliding plate 20, such that the first threaded rod 31 can rotate relative to the sliding plate 20. The length direction of the first threaded rod 31 is consistent with the length direction of the mounting plate 10. The mounting plate 10 is in screw fit with the first threaded rod 31 through a threaded hole, such that when the first threaded rod 31 rotates, it moves back and forth relative to the mounting plate 10, driving the sliding plate 20 to move back and forth, thereby adjusting the position of the sliding plate 20. A first screwing cap 32 is provided at one end of the first threaded rod 31 on the sliding plate 20, facilitating the rotation of the first screwing cap 32. The diameter of the first screwing cap 32 is larger than the thickness of the sliding plate 20, such that the first screwing cap 32 can be rotated from above or below the sliding plate 20, making the adjustment more convenient.
[0030] The adjusting component 40 includes second threaded rods 41 respectively arranged on both sides of the sliding plate 20 in a spiral manner, such that when the second threaded rods 41 rotate, the second threaded rods 41 move back and forth relative to the sliding plate 20. The two second threaded rods 41 are concentrically arranged with the first threaded rod 31. One end of each second threaded rod 41 is placed in the second opening 21 and is provided with a second screwing cap 42, facilitating the staff to rotate the second threaded rods 41. The diameter of the second screwing cap 42 is larger than the thickness of the sliding plate 20, such that the second screwing cap 42 can be rotated from above or below the sliding plate 20, making the adjustment more convenient. The second screwing cap 42 abuts against the adjacent clamping block 22, such that the second threaded rods 41 and the second screwing cap 42 move, pushing the clamping block 22 to move, thereby adjusting the position of the quartz torch tube. Specifically, when setting, in order to avoid a large contact area and excessive frictional force when the second screwing cap 42 directly contacts the clamping block 22, resulting in a large force required to rotate the second screwing cap 42, a contact rod 43 is concentrically arranged on the side of the second screwing cap 42 adjacent to the clamping block 22, and the end of the contact rod 43 abuts against the clamping block 22, facilitating the rotation of the second screwing cap 42. A fixing unit 50 is further provided on the mounting plate 10 for fixing the clamping block 22, thereby ensuring the stability of the quartz torch tube.
[0031] When setting, the fixing unit 50 includes two sliding rods 51 vertically arranged at the bottom of the mounting plate 10. The two sliding rods 51 are arranged at intervals along the length direction of the mounting plate 10. A pressing plate 52 is slidably arranged on the two sliding rods 51 together, so that the pressing plate 52 can slide up and down along the sliding rods 51. A third threaded rod 53 is vertically rotatably arranged at the bottom of the mounting plate 10 between the two sliding rods 51. The pressing plate 52 is in screw fit with the third threaded rod 53 through a threaded hole, so that when the threaded rod rotates, the pressing plate 52 is driven to slide. A locking plate 23 is arranged at the edge of the clamping block 22. The locking plate 23 is located between the pressing plate 52 and the mounting plate 10. Rotate the third threaded rod 53 to make the pressing plate 52 move towards the mounting plate 10, so as to clamp the locking plate 23 between the mounting plate 10 and the pressing plate 52, and the position of the clamping block 22 is fixed. Clamping grooves 24 are respectively formed on the opposite surfaces of the two clamping blocks 22, so that the quartz torch tube is fixed more firmly.
[0032] In this embodiment, the working principle of the front-back adjustment device for the torch tube of the ICP spectrometer is as follows: when the position of the quartz torch tube needs to be adjusted, first rotate the two second screwing caps 42 to drive the second threaded rod 41 to rotate, so that the second threaded rod 41 and the second screwing cap 42 move relative to the sliding plate 20, push the clamping block 22 to move, and adjust the position of the quartz torch tube. Subsequently, the two clamping blocks 22 accurately clamp the quartz torch tube at the center position of the working coil. Then rotate the first screwing cap 32 to drive the first threaded rod 31 to rotate, so that when the first threaded rod 31 rotates, it moves back and forth relative to the mounting plate 10, drives the sliding plate 20 to move back and forth, thereby finely adjusting the positions of the sliding plate 20 and the quartz torch tube, and accurately adjusting the front-back position of the plasma flame to be aligned with the optical path tube and the entrance slit, so as to obtain a better observation effect.
[0033] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
