Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for lithium battery detection, in particular to a protection mechanism for lithium battery detection equipment. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the very active chemical properties of lithium metal, lithium metal has very high environmental requirements during processing, storage, and use. With the development of science and technology, lithium batteries have become mainstream, and lithium battery testing equipment is required after production.

[0003] During actual use, existing lithium battery testing equipment needs to be connected through an interface and a plug so that the testing equipment can perform various tests on the lithium battery. However, when the connecting wires and the plugs are actually connected to the interfaces of the lithium battery testing equipment, they are generally directly plugged in without any protective measures. This causes the connecting wires or the plugs to easily become loose or detached from the interface when they are subjected to external forces such as touch or the influence of gravity. This not only affects the detection of the lithium battery, but also poses a major safety hazard during the detection process. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0028] like Figure 1 and Figure 2 As shown, a protective mechanism for lithium battery detection equipment provided by an embodiment of the utility model includes a first limit seat 1, a side of the first limit seat 1 is connected to a mounting side plate 2, a surface of the mounting side plate 2 is provided with a plurality of mounting holes 3, the length of the first limit seat 1 is the same as the length of the second limit seat 6, and the first limit seat 1 and the mounting side plate 2 are perpendicular to each other, and the first limit seat 1 and the second limit seat 6 are parallel to each other. Through the mutual cooperation of the mounting side plate 2 and the plurality of mounting holes 3, it is convenient for the staff to use the plurality of mounting holes 3 and external fixing screws to fix the mounting side plate 2 on the lithium battery detection equipment;

[0029] A lifting assembly is arranged on the outer side of the first limit seat 1, and a second limit seat 6 is connected to the outer side of the lifting assembly, and the lifting assembly is used to drive the second limit seat 6 to move;

[0030] A first rubber bag 8 is arranged inside the first limit seat 1, a second rubber bag 9 is arranged on the surface of the second limit seat 6 close to the first limit seat 1, a receiving cavity 7 is opened on the side of the first limit seat 1 close to the second limit seat 6, and the first rubber bag 8 is arranged inside the receiving cavity 7, and the interior of the first rubber bag 8 is hollow;

[0031] The lifting kit includes:

[0032] Both sides of the first limit seat 1 are connected with first supporting ears, and the surface of the first supporting ear is provided with a through hole, the inside of the through hole is connected with a first threaded rod 5, and the outer side of the first threaded rod 5 is meshedly connected with a butterfly nut 4;

[0033] One end of the first threaded rod 5 away from the first supporting ear is connected to the second supporting ear, and the side surface of the second supporting ear is connected to the side surface of the second limiting seat 6 .

[0034] In one embodiment of the utility model, when it is necessary to position and protect the plug connected to the lithium battery detection device and the connecting wire of the plug, firstly, the mounting side plate 2 is stably mounted on the plug interface area of ​​the lithium battery detection device through the plurality of mounting holes 3, and the plug interface is located between the first limit seat 1 and the second limit seat 6;

[0035] After the plug is inserted into the plug interface, the two butterfly nuts 4 are operated to rotate synchronously at the same time, and the two first threaded rods 5 jointly drive the second limit seat 6 to move upward by utilizing the threaded connection relationship between the butterfly nuts 4 and the first threaded rod 5, until the upper surface of the second limit seat 6 abuts against the bottom of the plug, and at this time, the second limit seat 6 provides upward support for the plug and the connecting wire;

[0036] It can be understood that when the plug is inserted into the plug interface, due to the position selection of the mounting side plate 2, the upper surface of the plug will fully contact the outer side of the first rubber bag 8, and then when the upper surface of the second limit seat 6 is against the bottom of the plug, the plug is in a state of being wrapped by the first rubber bag 8 and the second rubber bag 9, so that the plug can be more stably positioned between the first limit seat 1 and the second limit seat 6, and the first limit seat 1, the second limit seat 6, the first rubber bag 8 and the second rubber bag 9 can also provide good protection for the plug and the connecting wires.

[0037] Preferably, the surfaces of the first rubber bag 8 and the second rubber bag 9 that are close to each other are designed with a serrated structure. Through the above design, the friction between the first rubber bag 8 and the second rubber bag 9 and the plug can be increased to prevent the plug from accidentally sliding, and a certain space gap can be maintained between the first rubber bag 8 and the second rubber bag 9 and the plug to facilitate normal ventilation and heat dissipation of the plug.

[0038] Preferably, a supporting plate 15 is connected to the outer side of the second limit seat 6, and a groove recessed toward one side of the second limit seat 6 is provided on the surface of the supporting plate 15, and a protective plate 16 is connected to the end of the supporting plate 15 away from the second limit seat 6, and an arc-shaped groove is provided on the surface of the protective plate 16. Through the above design, the supporting plate 15 set at a horizontal angle cooperates with the protective plate 16 to effectively support the tail end of the plug, that is, the position of the connecting wire, to prevent the connecting wire of the plug from being pulled by external force and causing the plug to loosen at the socket of the lithium battery testing equipment, and at the same time can wrap and protect the connecting wire to prevent it from breaking.

[0039] like Figure 1-Figure 3 As shown, in one embodiment of the present utility model, a gas injection component is provided on the outside of the first limit seat 1 and inside the first rubber bag 8, and the gas injection component is used to inject gas into the first rubber bag 8 or extract the gas from the first rubber bag 8;

[0040] Gas injection components include:

[0041] A sealing can 10 is connected to the upper side of the first limit seat 1, and a threaded hole is provided on the surface of the sealing can 10, and a second threaded rod 11 is meshedly connected inside the threaded hole, a handle 12 is installed at one end of the second threaded rod 11, and a clamping sleeve 14 is movably clamped at the other end of the second threaded rod 11, a push block 13 is fixedly connected to the outside of the clamping sleeve 14, the second threaded rod 11 and the push block 13 are rotatably connected together through the clamping sleeve 14, a rubber layer is sleeved on the outside of the push block 13, and the outside of the rubber layer is tightly attached to the inner wall of the sealing can 10, so that a sealing structure is formed between the rubber layer and the sealing can 10;

[0042] The outer side of the sealing tank 10 is connected with a communication nozzle, and both ends of the communication nozzle are respectively connected with the inside of the sealing tank 10 and the inside of the first rubber bag 8 .

[0043] In this embodiment, by rotating the second threaded rod 11, the second threaded rod 11 can be rotated and lowered in the threaded hole and the inside of the sealed can 10, and the second threaded rod 11 will drive the push block 13 and the rubber layer to move downward inside the sealed can 10, and then the push block 13 and the rubber layer cooperate to squeeze the air in the sealed can 10 through the connecting nozzle and inject it into the first rubber bag 8 to expand it. Conversely, by adjusting the push block 13 to rise, the gas inside the first rubber bag 8 can be extracted to shrink the first rubber bag 8.

[0044] By means of the technical means of injecting and exhausting air into the first rubber bag 8, the second rubber bag 9 and the first rubber bag 8 can better wrap and limit the plug, so that the protective mechanism of the lithium battery testing equipment can provide good positioning measures for plugs of different specifications, thereby improving the application range of the protective mechanism of the lithium battery testing equipment.
