[0021] In view of this, a multi-zone sampling device for liquid samples is provided. Through the cooperation between the first slide groove, the slider and the cross plate, multi-zone sampling of samples is achieved with a simple structure. The operation is convenient and the problem of the complex structure of the existing device and the need for external power in the form of electric equipment is solved, which increases the cost of use and is not convenient for use in the outside world.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: By Figure 1-3 It can be seen that a liquid sample multi-region sampling device includes a shell 1, the outer side of the shell 1 is fixedly connected to a frame 3 through two brackets 2, the inner side of the frame 3 is processed with a first slide groove 4, and an adjustment mechanism is arranged above the shell 1. The adjustment mechanism includes a slider 5, a horizontal plate 6, a second slide groove 7, a square plate 8, a connecting rod 9, a square rod 10 and a rubber-tipped dropper 19. The outer side of the slider 5 is slidably connected to the inner side of the first slide groove 4, a side of the slider 5 is fixedly connected to a horizontal plate 6, and the inner side of the horizontal plate 6 is processed with a second slide groove 7. The slider 5 can move in the first slide groove 4, and the second slide groove 7 can be moved in the second slide groove 7. The inner side is movably connected with a square rod 10, which can move inside the second chute 7, and the two fit together. The outer side of the square rod 10 is movably connected with two square plates 8 that fit with the upper and lower sides of the horizontal plate 6. The front sides of the two square plates 8 are fixedly connected by a connecting rod 9, and the back side of the connecting rod 9 fits with the front side of the horizontal plate 6. Since the square rod 10 and the second chute 7 fit together, shaking during the movement is avoided. A rubber head dropper 19 is arranged on the outer side of the square rod 10. After squeezing the rubber ball, the rubber head dropper 19 can extract part of the liquid based on the principle of air pressure;

[0024] In the specific implementation process, it is worth pointing out that, through the cooperation between the first slide groove 4, the slider 5 and the horizontal plate 6, a simple structure is adopted to realize multi-region sampling of samples, which is convenient to operate and solves the problem that the existing device has a complex structure and adopts an electric device in the form of external power, which increases the use cost and is not convenient for use in the outside world.

[0025] Specifically, when using the liquid sample multi-region sampling device, the user can pull the horizontal plate 6 forward and backward to change the position, or pull the square rod 10 horizontally to change the position, and then sample through the rubber-tipped dropper 19 below.

[0026] Embodiment 2: By Figure 1-4 It can be seen that a frame 20 is installed on the outside of the rubber-tipped dropper 19, and a mounting hole 21 is processed on the outside of the square rod 10. The outside of the frame 20 is threadedly connected to the mounting hole 21 through screws;

[0027] In the specific implementation process, it is worth pointing out that the mounting holes 21 are set on the side of the square rod 10, and at most four rubber-tipped droppers 19 can be installed for sampling. After sampling, the square rod 10 is lifted and the carrier is placed under the rubber-tipped dropper 19 for discharge;

[0028] Furthermore, a first scale 18 is processed on the inner side of the housing 1, and a rubber plug 17 is provided in the through hole at the lower front side of the housing 1;

[0031] In the specific implementation process, it is worth noting that the stirring rod 16 can mix the liquid sample inside the housing 1 when rotating to avoid stratification;

[0032] Furthermore, a second scale 14 is processed on the front of the square rod 10, a plug 11 is installed on the top of the square rod 10, a vertical plate 13 is fixedly connected to the side of the square rod 10 by bolts 12, and the bottom of the vertical plate 13 is fixedly connected to the top of the upper square plate 8;

[0033] In the specific implementation process, it is worth pointing out that the bolts 12 on the vertical plate 13 can be pressed against the outer side of the square rod 10 for fixing, so as to prevent the square rod 10 from moving at will;

[0034] Specifically, on the basis of the above-mentioned first embodiment, the square rod 10, the rubber-tipped dropper 19 and the second scale 14 are coordinated to achieve the positioning of the sampling depth, and at the same time facilitate the user to continuously sample.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0036] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.
