Description

Technical Field

[0001] The utility model relates to the field of batteries, in particular to a battery and a charger. Background Art

[0002] A crane refers to a multi-action lifting machinery that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called an overhead crane, an aerial crane, or a crane. Some lifting equipment has the working characteristic of intermittent movement, that is, the corresponding mechanisms of taking materials, moving, unloading, etc. work alternately in a working cycle. The development and use of cranes in the market are becoming more and more extensive. Due to the lack of outriggers for lifting and traveling with heavy objects, accidents often occur, and the speed of travel is faster than that of crawler cranes (crawler cranes); the operation is stable, the lifting capacity is large, and the load can be lifted and traveled within a specific range, but the road must be flat and solid, the tire pressure must meet the requirements, and the lifting distance from the ground must not exceed 50CM; it is prohibited to travel long distances with loads. In order to ensure the safety of the operation, it is basically prohibited to carry out lifting operations without outriggers in China. The types of wire ropes used in cranes include phosphate-coated wire ropes, galvanized wire ropes, and smooth wire ropes. Among them, the remote controllers used in cranes still have certain shortcomings in actual application, such as:

[0003] The remote controller in the prior art is generally composed of a front shell and a rear shell, and a circuit board is arranged between the front and rear shells. Function buttons are arranged on the front of the front shell, and a battery chamber is arranged in the lower half of the rear shell, and a rear cover is arranged on the battery chamber. The connection method of the rear cover and the rear shell is generally as follows: one or two insertion strips are convexly arranged at the front end of the battery cover, and an elastic tongue is arranged at the rear end; the battery chamber is correspondingly provided with one or two slots corresponding to the insertion strips at its front end, and a card slot corresponding to the elastic tongue is arranged at the rear end. When in use, the insertion strip at the front end of the battery cover is first inserted into the slot of the battery chamber, and then the rear end of the battery cover is pressed down so that the card tongue at the rear end of the battery cover is connected to the card slot at the rear end of the battery chamber, so that the battery cover can be fixed on the battery chamber.

[0004] During use, when the remote control falls or drops, the back cover may separate from the rear shell when it collides, causing the battery to loosen and fall off. Remote controls used for special equipment usually have a password. When the battery falls off, the remote control will lose power, causing the password to be lost and need to be reset, which reduces work efficiency and cannot meet usage needs. Utility Model Content
