[0002] Batteries have been widely used due to their reliable quality, large capacity range, easy maintenance and long service life. With the development of the times and the improvement of people's living standards, the types and quantity of industrial batteries are increasing rapidly. The types of industrial batteries are becoming more and more diverse, and the requirements for product quality are also getting higher and higher.

[0003] At present, the battery pole is generally sealed in the pole hole of the battery cover with sealant, and the pole terminal is led out from the pole. The pole terminal is connected to the pole by welding. After sealing the cover, the worker uses a welding gun to weld one end of the pole terminal to the pole, and the other end of the pole terminal extends out of the pole hole.

[0004] As the production and demand of batteries gradually increase, batteries are usually stacked in packaging boxes during packaging and transportation. When stacked, the terminal poles of the bottom batteries will be squeezed by the gravity of the upper batteries, causing the terminal poles of the batteries to collapse. This makes it inconvenient to stack the batteries and it is not convenient to store each battery in a contactless and layered manner. The collapsed terminal poles affect the use of the battery terminal poles, the quality and pass rate of the batteries, and may even cause the batteries to be scrapped. Utility Model Content

The protective structure includes a protective cover that can cover the pole terminal and an opening portion for facilitating the protective cover to be inserted into the pole terminal. The opening portion is located on one side of the protective cover and is connected to the protective cover. Two anti-pressure columns are fixed to the bottom end of the protective cover, and the two anti-pressure columns are symmetrically fixed on both sides of the bottom end of the protective cover.

[0007] Furthermore, the protective structure includes a detection slot, which is located at the top of the protective cover.

[0008] Furthermore, the protective structure includes a position-limiting sealing portion, which is fixed to the other side of the protective sleeve and is opposite to the opening portion.

[0009] Furthermore, at least two reinforcing ribs are fixed inside the protective cover, and the two reinforcing ribs are fixed inside the protective cover at intervals.

[0010] Furthermore, the protective cover, the opening, and the two anti-pressure columns are integrally injection molded.

[0011] On the other hand, the utility model also provides a battery cover, including a battery cover with the protective cover as described above, the battery cover including a pole hole, a pole terminal, and a pole, the pole being fixed in the pole hole, one end of the pole terminal being welded to the upper end of the pole, the other end of the pole terminal extending outward from the pole hole, and the protective cover being sleeved on the pole terminal.

[0012] Furthermore, an insulating sealing ring is fixed between the pole and the pole hole, and the pole terminal is fixed in the pole hole through the pole at the lower end.

[0013] Furthermore, a battery slot is fixed below the battery cover.

[0014] Compared with the prior art, the solution of the present invention has at least the following beneficial effects:

[0015] The protective structure of the present invention includes a protective sleeve that can cover the terminal post and an opening that facilitates the sleeve's insertion into the terminal post. The opening is located on one side of the protective sleeve and communicates with the sleeve. Two anti-pressure posts are fixed to the bottom end of the protective sleeve, symmetrically fixed on either side of the bottom end of the protective sleeve.
