Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte samplers, in particular to a lithium battery electrolyte sampler. Background Art

[0002] Lithium-ion batteries are secondary batteries that mainly rely on the movement of lithium ions between the positive and negative electrodes to work. They are widely used in mobile phones, electric vehicles and other fields. The electrolyte of lithium-ion batteries is generally composed of lithium salts, organic solvents and additives. During the production process of the electrolyte, strict requirements are placed on each component, so a sampler is required to take samples and test them.

[0003] When a traditional sampler is used to sample and test lithium-ion batteries, the extraction port of the sampler is first inserted into the connecting tube on the lithium-ion battery storage barrel, and then the pull-out rod on the sampler is operated to extract the electrolyte. The electrolyte is then transferred to the corresponding equipment for testing. However, in actual use, it was found that when the staff held the sampler, the sampler would shake due to the shaking of the hand, making it difficult for the sampler to stably dock with the storage barrel, and it would loosen and detach, affecting the stable extraction of the electrolyte and reducing the practicality and use effect of the sampler. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a lithium battery electrolyte sampler, comprising a storage barrel, a sampler body is inserted into the surface of one side of the storage barrel, a stabilizing device is provided on the surface of the sampler body, the stabilizing device comprises two mounting frames, the two mounting frames are respectively fixedly connected to the arc surface of the sampler body, the inner walls of the two mounting frames are respectively penetrated by a rotating shaft connected for rotation, a rotating plate is fixedly connected to the arc surface of the rotating shaft, both ends of the rotating shaft are respectively fixedly connected to a fixed block, torsion springs are respectively sleeved on the arc surfaces on both sides of the rotating shaft, the two ends of the torsion spring are respectively fixedly connected to the mounting frame and the fixed block, the surface of the storage barrel is fixedly connected to two connecting plates, one side surface of the two connecting plates is respectively provided with a fixing groove, and the rotating plate is clamped with the inner wall of the fixing groove.

[0006] The effect achieved by the above components is that the sampler body can be more stably plugged into the storage barrel when sampling, and is not prone to loosening or detaching, thereby ensuring stable extraction of the electrolyte, better testing of the electrolyte, improving the use effect and practicality of the sampler body, and facilitating the operation of the staff.

[0007] Preferably, a reinforcement pad is fixedly connected to one side surface of the rotating plate, and the reinforcement pad is a rubber pad.

[0008] The effect achieved by the above components is: through the setting of the reinforcement pad, the friction force is further increased when the fixed groove and the rotating plate are clamped with each other, making the clamping more stable, so that the sampler body can better maintain the assembly stability and better perform electrolyte sampling and extraction.

[0009] Preferably, an operating block is fixedly connected to one side surface of the rotating plate, and a surface of the operating block is provided with a plurality of anti-slip protrusions.

[0010] The effect achieved by the above components is: through the setting of the operating block, after the sampling is completed, the sampler body is pulled to pull the operating block to rotate the rotating plate, thereby disengaging the rotating plate from the fixed groove on the surface of the connecting plate, and removing the sampler body from the storage barrel, thereby improving the convenience of using the stabilization device.

[0011] Preferably, the inner walls of the two installation frames are respectively fixedly connected with positioning blocks, and the positioning blocks abut against the surface of the rotating plate.

[0012] The effect achieved by the above components is: through the setting of the positioning block, the rotating plate is ensured to have a stable position when it contacts and squeezes the positioning block under the torsional force of the torsion spring, thereby facilitating the mutual engagement of the rotating plate and the connecting plate.

[0013] Preferably, the cross-section of one side surface of the two connecting plates is arc-shaped, and the size of the connecting plates is compatible with the rotating plates.

[0014] The effect achieved by the above components is: through the special cross-section setting of the connecting plate, when the connecting plate is engaged with the rotating plate, when the connecting plate is inserted into the installation frame, it can slide along the arc-shaped cross-section, thereby improving the convenience of using the stabilizing device.

[0015] Preferably, an auxiliary device is provided on the surface of the sampler body, and the auxiliary device includes an assembly frame, which is fixedly connected to the surface of the sampler body. An assembly block is clamped on the inner wall of the assembly frame, and a convenient ring is fixedly connected to one side surface of the assembly block.

[0016] The effect achieved by the above components is: when extracting the electrolyte, the staff holds the sampler body and buckles the index finger on the inner wall of the convenient ring. At this time, the staff can hold the sampler body more stably, better ensure the stable sampling of the electrolyte, and improve the use effect and practicality of the sampler body.

[0017] Preferably, a protective ring is fixedly connected to the inner wall of the convenient ring, and the protective ring is a sponge ring.

[0018] The effect achieved by the above components is that the protective ring can protect the fingers of the staff when they are buckled in the convenient ring, so that the fingers are not easily strangled due to excessive squeezing force.

[0019] Preferably, bolts are inserted through the surface of the assembly block, and the bolts are threadedly connected to the inner wall of the assembly frame.

[0020] The effects achieved by the above components are: through the setting of the bolts, the connection between the assembly block and the assembly frame is more stable and firm, thereby making the installation of the convenient ring more stable, thereby better assisting the sampler body to sample the electrolyte.

[0021] In summary, the beneficial effects of the present invention are as follows:

[0022] When sampling, the sampler body can be more stably plugged into the storage barrel and is not prone to loosening or detaching, thereby ensuring stable extraction of the electrolyte, better testing of the electrolyte, improving the use effect and practicality of the sampler body, and facilitating operation by staff.

An operating block 39 is fixedly connected to one side surface of the rotating plate 33. The surface of the operating block 39 is provided with a number of anti-slip protrusions. Through the provision of the operating block 39, after the sampling is completed, the sampler body 2 pulls the operating block 39 to rotate the rotating plate 33, thereby disengaging the rotating plate 33 from the fixing groove 37 on the surface of the connecting plate 36, and removing the sampler body 2 from the storage barrel 1, thereby improving the convenience of using the stabilizing device 3.

Through the setting of the bolt 45, the connection between the assembly block 42 and the assembly frame 41 is more stable and firm, so that the installation of the convenient ring 43 is more stable, and then the sampler body 2 is better assisted in sampling the electrolyte.

[0034] Working principle: When extracting and testing the electrolyte of a lithium battery, first insert one end of the sampler body 2 into the connecting tube on the surface of the storage barrel 1.
