Cylindrical battery mounting box

Abstract

The invention relates to a cylindrical battery mounting box which comprises a cylindrical barrel (6), and is characterized in that one end of the cylindrical barrel (6) is set to be horn-mouth-shaped; a pressing device is movably arranged in the other end of the cylindrical barrel in a sleeving manner and comprises a horn-mouth-shaped fixing piece (3) and a screw (5) matched with a thread (4) in the inner wall of the cylindrical barrel in the rear of the fixing piece. The cylindrical battery mounting box disclosed by the invention is simple in structure and can be used for mounting cylindrical batteries (1) of various sizes and specifications, and the universal performance of the battery is improved.

Description

technical field [0001] The invention relates to a lithium battery fixing device, in particular to a cylindrical battery installation box capable of adapting to cylindrical lithium batteries of different specifications and sizes. Background technique [0002] At present, it is known that small appliances such as remote controls, water heaters, and electric toys are equipped with battery boxes inside, and cylindrical batteries such as No. 5 and No. 7 are installed in the battery box, and the electrodes at both ends of the battery are connected by springs and contacts To output current to electrical appliances, the battery type must match the size of the battery box, that is, a battery box can only use a cylindrical battery that matches its size. If the cylindrical battery is too large, it cannot fit into the battery box. If it is small, The electrodes at both ends of the battery cannot be fully contacted with the springs and contacts and cannot supply power to electrical appli...

Problems solved by technology

[0002] At present, it is known that small appliances such as remote controls, water heaters, and electric toys are equipped with battery boxes inside, and cylindrical batteries such as No. 5 and No. 7 are installed in the battery box, and the electrodes at both ends of the battery are connected by springs and contacts To output current to electrical appliances, the battery type must match the size of the battery box, that is, a battery box can only use a cylindrical battery that matches its size. If the cylindrical battery is too large, it cannot fit into the battery box. If it is small, The electrodes at both ends of the battery are not in full contact with the springs and contacts and cannot supply power to electrical appliances. Therefore, the current battery box limits the size and specification of the battery that can be used, and the universal performance of the battery is not high.

In addition, the batteries of notebooks and electric vehicles are powered by multiple 3.6V cylindrical lithium batteries connected in series and parallel. Due to the high power of notebooks and electric vehicles, the requirements for batteries are relatively high, and small appliances such as remote controls The requirements for batteries are relatively low. After the battery reaches the service life of notebooks and electric vehicles, its electric energy storage capacity is still very considerable. It is also inappropriate to use directly on small electrical appliances, there must be a suitable connection device
