In the production process of electrolytic copper foil, the electrolyte plays the role of conductive and chemical reaction medium. Regular inspection and adjustment are required to ensure the quality of electrolytic copper foil and the stability of production. The sampling detection device is usually used to regularly extract samples from the electrolyte for chemical analysis, conductivity measurement, etc., so as to understand the current state of the electrolyte, predict its service life, and promptly discover and solve potential problems.

[0003] After searching, the Chinese patent application number 200420080216.5 discloses a device for testing the density or specific gravity of a material, and particularly relates to a density meter for measuring lead-acid electrolyte, which includes a shell, a weight and scale lines. The shell is hollow inside, the weight is located at the bottom of the shell, and scale lines are distributed on the shell. The main structural point is that the shell is a plastic tube and has a first tube body and a second tube body, and the first tube body and the second tube body are fixedly connected. The density meter has a simple manufacturing process, low cost, is not easy to damage, is easy to use and safe;

[0004] The existing sampling and detection devices still have the following shortcomings during use: since the sampling tubes of the existing sampling and detection devices are generally directly exposed to the external environment, foreign matter or dust may enter the internal channel of the sampling tube, causing the sampling tube on the device to be blocked during the sampling process, seriously affecting the sampling efficiency of the sampling tube, and the rubber ball head will age after long-term use and it is difficult to provide effective suction, and it is inconvenient to replace and maintain it in the existing technology, affecting the overall service life.

[0005] Therefore, there is an urgent need for an electrolytic copper foil electrolyte sampling and detection device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to address the problem that the existing sampling tube is directly exposed, which makes it easy for dust or foreign matter to enter its internal channel, thereby causing blockage, affecting the efficiency of electrolyte sampling and detection when the sampling tube is used later.

[0007] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0008] A device for sampling and detecting electrolyte of electrolytic copper foil comprises a sampling tube, a connector is fixedly connected to the top of the sampling tube, a dust shielding structure is arranged on the outside of the sampling tube, a liquid storage tube is screwed to the outside of the connector, a second sealing ring is sleeved on the outside of the connector, a protective structure is arranged on the outside of the liquid storage tube, a connecting ring is fixedly connected to the top of the liquid storage tube, a connecting tube is connected to the top of the connecting ring, a rubber ball head is screwed to the outside of the connecting tube, a first sealing ring is sleeved on the outside of the connecting tube, a densitometer is arranged inside the liquid storage tube, and the dust shielding structure comprises a dust shielding cover, a holding portion, a magnet bar and an iron bar, and the iron bar is embedded inside the bottom end of the connecting tube.

[0009] As a preferred technical solution of the present application, the dust cover is sleeved on the outside of the sampling tube, a magnetic strip is embedded inside the top of the dust cover, and a holding portion is connected to the bottom of the dust cover.

[0010] As a preferred technical solution of the present application, the magnetic strip in the dust cover is in contact with the iron strip in the connector, and both the magnetic strip and the iron strip are annular in design.

[0011] As a preferred technical solution of the present application, the protective structure includes a support block, a positioning pin, a protective sleeve and an anti-slip strip. The support blocks are connected to both sides of the bottom of the connecting ring. The interior of the support block is screwed with a positioning pin. The protective sleeve is mounted on the outside of the liquid storage tube, and the outside of the protective sleeve is provided with an anti-slip strip.

[0012] As a preferred technical solution of the present application, the positioning pin passes through the support block and is inserted into the interior of the protective sleeve, and the anti-slip strips are provided in multiple groups, and the multiple groups of anti-slip strips are distributed at equal intervals.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the scheme of this application:

[0015] 1. The dust shielding structure can be used to isolate the sampling tube from dust. The holding part is provided to facilitate the user to hold the tube. Then, the holding part can be held to drive the dust shielding cover to be aligned and sleeved on the surface of the sampling tube. Then, the dust shielding cover is pushed up to drive the magnetic strip inside the dust shielding cover to contact and tighten with the iron strip in the connector to fix the dust shielding cover, so as to ensure the stability of the dust shielding cover. When the dust shielding cover covers the sampling tube when it is not in use, dust or odor can be prevented from entering the channel of the sampling tube.

[0016] 2. The liquid holding tube can be protected by setting a protective structure. A rubber protective sleeve is put on the surface of the liquid holding tube for protection to prevent the glass liquid holding tube from being easily damaged by stress. At the same time, the two sets of positioning pins are rotated in sequence so that the positioning pins are engaged with the threads in the support block and gradually inserted into the protective sleeve to hold it in place and reduce the occurrence of sliding and shifting. The setting of multiple sets of anti-slip strips can increase the friction between the staff's hands and the protective sleeve to reduce the occurrence of slipping and falling off the hands. The rubber ball head can be replaced according to its aging condition without the need for overall replacement, thereby reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
