Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a manual sampling depth adjustment device. Background Art

[0002] Using a spectrometer to test liquids can quickly and accurately obtain information about the characteristics of the liquid, which has important application value in the evaluation of liquid corrosiveness and quality control. The specific detection method is to place the liquid sample to be tested in the sample chamber of the spectrometer for testing. The spectrometer irradiates the sample and measures the sample's absorption, scattering, transmission and other characteristics of light of different wavelengths. It can obtain the sample's spectral image and analysis results, and then analyze the composition, concentration, corrosiveness and other characteristics of the liquid.

[0003] The existing detection sampling method usually uses an atomizer and a sampling tube to introduce a corrosive liquid into a test tube by atomization. Once the sampling tube falls to the bottom of the test tube, the atomizer will be blocked. Therefore, the sampling tube needs to be manually supported. However, this process is relatively slow and manual support is very inconvenient. Therefore, a manual sampling depth adjustment device is proposed. Utility Model Content

[0004] In order to solve the technical problem that the existing spectrometer detection sampling requires manual hand-holding of the sampling tube, and the sampling process is slow, which makes manual hand-holding very inconvenient, the utility model provides a manual sampling depth adjustment device.

[0006] Through the above technical scheme, after the sampling tube is inserted into the mounting cover through the jack, the sampling tube is stably clamped by two sets of clamping parts, so that the sampling tube can maintain a stable position in the sample tube, effectively avoiding the situation where the sampling tube mouth is in contact with the bottom wall of the sample tube, avoiding the blockage of the atomizer, and stably injecting reagents. There is no need to manually hold the sampling tube, which greatly improves the convenience of operation; and the mounting cover, fixing pile and sample tube are all made of anti-corrosion plastic material, preferably polytetrafluoroethylene material, which effectively avoids corrosion of the adjustment device, and the mounting cover is subsequently cleaned and maintained to achieve the reuse of the mounting cover.

[0007] As a further improvement of the above scheme, a telescopic groove is opened on one side wall of the fixed pile, the telescopic groove faces the insertion hole, a reset spring is connected to the inner wall of the telescopic groove, one end of the reset spring is connected to a telescopic rod, and one end of the telescopic rod is fixedly connected to the clamping member; through the cooperation of the telescopic rod and the reset spring, the interior of the telescopic groove is in a sealed state, which effectively avoids the situation where the reset spring is corroded by acidic liquid.

[0008] As a further improvement of the above solution, a through hole is penetrated through the inner wall of the telescopic groove, a pull rod is fixedly connected to the other end of the telescopic rod, the pull rod is slidably matched with the through hole, and a shift plate is fixedly connected to one end of the pull rod.

[0009] Through the above technical solution, the reset spring cooperates with the telescopic rod to make the clamping piece have a good reset effect, and at the same time can flexibly clamp sampling tubes of different sizes; and the limit of the clamping piece can be quickly released through the dial plate, so that the clamping height of the sampling tube can be easily adjusted, thereby improving the flexibility of use.

[0010] As a further improvement of the above solution, the inner diameter of the jack is larger than the outer diameter of the injection tube.

[0011] As a further improvement of the above solution, a plurality of buckle grooves are provided on the side surfaces around the installation cover, and a sealing plug is provided on the bottom surface of the installation cover, and the sealing plug is made of anti-corrosion plastic material.

[0012] As a further improvement of the above solution, the fixing pile and the sample tube are both made of polytetrafluoroethylene.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model discloses a manual sampling depth adjustment device, which stably clamps the sampling tube by two groups of clamping parts, so that the sampling tube can maintain a stable position in the sample tube, effectively avoiding the situation that the sampling tube mouth is in contact with the bottom wall of the sample tube, avoiding the blockage of the atomizer, and can stably inject reagents without manually holding the sampling tube, thereby greatly improving the convenience of operation; and the mounting cover, the fixing pile and the sample tube are all made of anti-corrosion plastic, which effectively avoids the corrosion of the adjustment device and is more durable.
