[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , an embodiment provided by the present invention: A liquid metering detector convenient for sampling, including:

[0024] Bottom plate 1, and a measuring cup 2 is fixedly connected above the bottom plate 1;

[0025] Guide cylinder 3, the guide cylinder 3 is fixedly connected to the upper surface of the bottom plate 1, and an adjusting rod 4 is damping inserted inside the guide cylinder 3. The top of the adjusting rod 4 is fixedly connected with a rotating seat 5. A rotating frame 6 is rotatably connected between the two rotating seats 5. Through its up-and-down sliding, the height of the rotating frame 6 can be adjusted. At the same time, through the rotation of the rotating frame 6, the sampling cylinder 8 is driven to be inclined, so as to facilitate the addition and injection of samples. And when the guide cylinder 3 and the adjusting rod 4 are in a contracted state, the lowest point of the sampling cylinder 8 is above the inner wall of the measuring cup 2;

[0026] Guide rod 11 and threaded rod 12, the guide rod 11 and the threaded rod 12 are both fixedly connected to the upper surface of the rotating frame 6, and a guide plate 14 is sleeved outside the guide rod 11 and the threaded rod 12. The bottom of the guide plate 14 is fixedly connected with a push-pull rod 15. A nut 17 is threadedly connected to the outside of the threaded rod 12. Through the threaded connection of the threaded rod 12 and the nut 17, the auxiliary limit of the guide plate 14 can be realized by adjusting the position of the nut 17, so as to accurately control the amount of samples extracted inside the sampling cylinder 8;

[0027] Sampling cylinder 8, the sampling cylinder 8 is fixedly connected to the center of the rotating frame 6, and a push-pull rod 15 is inserted inside the sampling cylinder 8. The bottom of the push-pull rod 15 is fixedly connected with a rubber plug 16. Through the push and pull of the push-pull rod 15 and the rubber plug 16, the inside of the sampling cylinder 8 can be sampled. And the setting of the rubber of the rubber plug 16 improves the sealing effect and can avoid adhesion to the inner wall of the sampling cylinder 8 when the sample is pushed out.

[0028] Furthermore, there are two sets of guiding cylinders 3, adjusting rods 4 and rotating seats 5, and the two sets of guiding cylinders 3, adjusting rods 4 and rotating seats 5 are symmetrically distributed on both sides of the measuring cup 2, and are supported synchronously on the same side, improving the stability of the support.

[0029] Furthermore, the center of the rotating frame 6 is in a plate-like structure, and a positioning hole adapted to the sampling cylinder 8 is opened in the center of the plate-like structure. Both ends of the rotating frame 6 are in a cylindrical shape. Through the rotation connection of the rotating frame 6, it is convenient to tilt the sampling cylinder 8 at an angle, and then it is convenient to push out the sample in the sampling cylinder 8 after sampling. Moreover, the bottom of the sampling cylinder 8 is made of metal material and has a certain weight, so that in its initial state, the sampling cylinder 8 hangs naturally.

[0030] Furthermore, a sealing cover 10 is threadedly connected to the top of the sampling cylinder 8, and a guiding hole adapted to the sliding of the push rod 15 is opened in the center of the sealing cover 10. This sliding connection further improves the stability of the up and down adjustment of the push rod 15.

[0031] Furthermore, a handle 7 is fixedly connected to the outer wall of the rotating frame 6, and the handle 7 is distributed obliquely. There are two sets of handles 7 symmetrically distributed. Through the setting of the handle 7, it is convenient to hold and control the device. By holding the handle 7, the height adjustment and angle adjustment of the rotating frame 6 are realized, thus improving the flexibility of the overall use of the device.

[0032] Furthermore, a traction rod 9 is fixedly connected to the upper surface of the guiding plate 14, and guiding cylinders 3 are fixedly connected to the tops of the guiding rod 11 and the threaded rod 12. The top of the traction rod 9 penetrates above the top plate 13. Through the pulling of the traction rod 9, the lifting control of the guiding plate 14 and the push rod 15 is realized.

[0033] Furthermore, scale lines are provided on the outer wall of the guiding rod 11. The guiding rod 11 and the threaded rod 12 have the same diameter, and the top plate 13 is slidably connected to the guiding rod 11 and the threaded rod 12 up and down, and the nut 17 is used for abutting and limiting the top plate 13. Through the setting of the scale lines, it is convenient for measurement control and improves the accuracy of measurement.

[0034] Working principle: The sampling cylinder 8 and the rubber plug 16 used in this application are both products that can be directly purchased on the market, and their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here. When this utility model is in use, first place the bottom of the sampling cylinder 8 inside the measuring cup 2, pull the traction rod 9 upward, so that the guiding plate 14 drives the push rod 15 to move upward, completing the extraction of the sample inside the sampling cylinder 8. At the same time, through the position adjustment of the nut 17, the position of the guiding plate 14 is controlled to achieve accurate measurement of the sample extraction.

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
