Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application provides a safety protection device for lithium battery cover testing equipment, which solves the problem that traditional protective covers have limited functions and the protective doors are manually closed and locked, which is easy to forget during operation, resulting in the protective doors becoming loose or open during testing, thus posing a risk.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a safety protection device for a lithium battery cover plate testing equipment, according to the attached... Figure 1-4 As shown, the device includes a protective cover body 1 installed on the testing equipment, and a front protective door 2 is rotatably connected to the protective cover body 1; the front protective door 2 is provided with an observation window 21. The device, through the design of the observation window 21, allows for easy and intuitive observation of the state of the lithium battery cover during lithium battery testing.

[0025] A handle 22 is provided on the front protective door 2. The design of the handle 22 makes the front protective door 2 easy to operate during opening and closing.

[0026] The back of the protective cover body 1 is movably attached to the maintenance back plate 11. The design of the maintenance back plate 11 makes it easy to open the back of the protective cover body 1, thereby making it easy to perform specific maintenance operations on the back of the entire testing equipment. The maintenance back plate 11 is fixed to the protective cover body 1 by bolts, which makes it easy to disassemble and assemble the maintenance back plate 11.

[0027] The front protective door 2 is provided with a plug 3, and the plug 3 is provided with a locking groove 31;

[0028] The protective cover body 1 is equipped with a safety door lock 4 inside, and the safety door lock 4 is equipped with a locking mechanism 5 inside;

[0029] The locking mechanism 5 includes a motor 51 installed inside the safety door lock 4 and a lead screw 52 installed at the output end of the motor 51. An adjustment table 53 is threadedly connected to the lead screw 52. The adjustment table 53 is slidably connected inside the safety door lock 4. The adjustment table 53 is provided with multiple sets of locking rods 54 that are movably inserted into the locking groove 31.

[0030] The safety protection device for this lithium battery cover testing equipment provides protection for the position of the lithium battery cover testing equipment through the protective cover body 1 and the front protective door 2. The device has a good protective effect and makes it convenient to put in and take out the lithium battery cover, achieving all-round protection for lithium battery cover testing. The opening and closing operation of the front protective door 2 is convenient. When the front protective door 2 is closed for lithium battery cover testing, the locking mechanism 5 locks the position of the insert block 3 and the safety door lock 4, thus ensuring the good protective effect of the protective device.

[0031] The safety door lock 4 has a first limiting plate 55 and a second limiting plate 56 inside. A guide rod 57 is fixedly connected between the first limiting plate 55 and the second limiting plate 56. The guide rod 57 is used to support the adjustment table 53. The locking mechanism 5 has a simple structure and is easy to operate.

[0032] When the front protective door 2 needs to be closed and tested, the front protective door 2 is rotated directly, so that the front protective door 2 drives the insert block 3 to be inserted into the interior of the safety door lock 4. When the lithium battery cover needs to be tested, the insert block 3 and the front protective door 2 are quickly locked by the locking mechanism 5.

[0033] The locking process is as follows: first, the motor 51 drives the lead screw 52 to rotate, and then the lead screw 52 drives the adjustment table 53 to move. The adjustment table 53 slides along the guide rod 57 and pushes the locking rod 54 to move. Finally, the locking rod 54 is inserted into the inside of the locking groove 31.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
