Description

Technical Field

[0001] The utility model relates to the technical field of analytical chemical sampling, in particular to a sampling titration device for detection experimental analysis. Background Art

[0002] Analytical chemistry is a science about analytical methods and theories for studying chemical information such as the composition, content, structure and morphology of substances. It is an important branch of chemistry. It is used to identify what components a substance contains and what components the substance is composed of, to determine the relative content of various components, and to study the molecular structure or crystal of substances. Currently, in the process of detection and use, a sampling titration device is needed to drop the sampled liquid onto the detection experimental analysis equipment.

[0003] After searching, a Chinese patent with publication number CN215445956U discloses a liquid sampling device for chemical and chemical analysis and testing, which relates to the technical field of sampling devices, including a first hard tube, a suction head, a first fixed block and a second fixed block, the bottom end of the first hard tube is fixedly provided with a suction head, the top of the first hard tube is provided with a first fixed block, the top of the first fixed block is provided with a straight groove, the top of the first hard tube is fixedly penetrated through the bottom end of the first fixed block and extends to the inside of the straight groove, the inside of the straight groove is provided with a telescopic tube, and the bottom end of the telescopic tube is connected to the first hard tube. The utility model rotates the movable ring to separate the movable ring from the first fixed block, at this time, the second fixed block is pulled upward, the second fixed block drives the second hard tube to move, and the telescopic tube is driven and extended by the second hard tube, so that the length of the entire dropper is increased, which is conducive to conveniently adjusting the length of the dropper, and is conducive to conveniently adapting to different bottle heights, reducing the number of droppers in the laboratory, facilitating management and placement, and improving practicality. Its technical key points are: adjusting the length of the dropper so that the dropper is suitable for different bottles.

[0004] The above solution solves the problem of difficulty in adjusting the length of the dropper, but there are still some shortcomings in actual use. For example, during use, the sample is squeezed out by squeezing the rubber head. However, it is difficult to accurately control the amount of sample squeezed out when manually squeezing the rubber head, which makes it easy for the sample to be squeezed out too much.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has the disadvantage that it is difficult to accurately control the amount of sample extruded when manually extruding the rubber head, which leads to the disadvantage that the sample is easily extruded too much.

[0007] The utility model discloses a sampling titration device for detection experiment analysis, comprising a connecting tube, a suction head is fixedly connected to the left side of the connecting tube, a connecting tube is fixedly connected to the upper surface of the connecting tube, a rubber head is fixedly connected to the top of the connecting tube, a piston head is slidably connected to the inner wall of the connecting tube, a control board is fixedly connected to the right side of the piston head, a threaded tube is fixedly connected to the right side of the control board, a bearing is fixedly inlaid on the right side of the connecting tube, a threaded rod is fixedly connected to the inner wall of the bearing, the left end of the threaded rod extends to the interior of the threaded tube, and the threaded rod is threadedly connected to the threaded tube.

[0008] By adopting the above scheme, since the traditional extrusion sample relies on manual extrusion of the rubber head, the sample extrusion amount is difficult to control accurately. By providing a threaded connection between a threaded rod and a threaded barrel, the threaded rod can control the threaded barrel to rotate, so that the threaded barrel pushes the control plate and the piston head to move, and then the piston head can slowly push the experimental sample out, thereby accurately controlling the extrusion amount.

[0009] Optionally, two sliding cylinders are fixedly connected to the right side surface of the control panel, the inner wall of each sliding cylinder is slidably connected to a sliding rod, and the right end of each sliding rod is fixedly connected to the inner wall of the connecting cylinder.

[0010] By adopting the above solution, the control board can be limited by providing a slide cylinder and a slide rod, so that the control board is more stable during the movement and the control board is prevented from rotating.

[0011] Furthermore, a support seat is fixedly connected to the outer surface of the threaded cylinder, and a left side surface of the support seat is fixedly connected to a right side surface of the control panel.

[0012] By adopting the above solution, the threaded barrel can be reinforced by the support seat, the stability of the connection between the threaded barrel and the control board is increased, and the threaded barrel is prevented from falling off during long-term operation.

[0013] Furthermore, a limiting ring is fixedly connected to the inner wall of the connecting cylinder, and the limiting ring is located on the left side of the piston head.

[0014] By adopting the above solution, the connection cylinder can be limited by providing a limiting ring to prevent the threaded cylinder from separating from the threaded rod.

[0015] Furthermore, an operating plate is provided on the right side of the connecting tube, a left side surface of the operating plate is fixedly connected to the right end of the threaded rod, and a group of anti-slip grooves arranged in an annular manner are provided on the outer surface of the operating plate.

[0016] By adopting the above solution, the operating panel can control the rotation of the threaded rod and avoid hand slippage when rotating the threaded rod.

[0017] Furthermore, an anti-skid sleeve is fixedly connected to the outer surface of the connecting tube, and a group of anti-skid grooves are formed on the outer surface of the anti-skid sleeve.

[0018] By adopting the above solution, the anti-slip sleeve can increase the friction force on the surface of the connecting tube, thereby avoiding the phenomenon of hand slipping and falling off during use.

[0019] Furthermore, two groups of scale grooves are formed on the outer surface of the connecting tube, and each of the scale grooves is located on the left side of the connecting tube.

[0020] By adopting the above solution, the graduated groove can measure the sample sucked, so that the staff can understand the amount of sample extruded and sucked.

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] 1. The utility model is provided with a rubber head so that the device can quickly suck in and extrude the sample, and by utilizing the threaded connection between the threaded rod and the threaded barrel, the threaded barrel can drive the control plate to move slowly, so that the control plate pushes the piston head to move slowly, and then the piston head slowly extrude the sample, thereby accurately controlling the amount of sample extrusion.

[0023] 2. The utility model utilizes the slide cylinder and the slide rod to limit and guide the control board during its movement, so that the movement of the control board is more stable and the control board is prevented from rotating. The scale groove can be used to observe the amount of sample suction and the amount of sample extrusion, so that the staff can understand the amount of sample sucked in and extruded.
