Description

technical field [0001] The invention relates to a charging stand, in particular to a waterproof charging stand. Background technique [0002] Charging stand is a kind of accessory for charging electrical appliances, which is widely used in electric tools, flashlights, etc., and its structure generally includes a charging stand body, which includes a fixing seat made of insulating material, a positive terminal and a negative shrapnel , one end of the fixed seat is connected to a charging circuit board, the other end of the fixed seat is provided with a charging socket, the positive terminal is fixedly connected in the fixed seat, and the tail end of the positive terminal is in contact with the charging circuit board, and the positive terminal The free end of the terminal is set in the charging socket of the fixed seat; the tail end of the negative spring is fixedly connected to the fixed seat, and the fixed seat is provided with an opening for the free end of the negative spr...

AI Technical Summary

Problems solved by technology

Some waterproof charging stands have also appeared at present, such as the rechargeable flashlight of Chinese patent 2005100489235. The charging stand in its disclosed technical solution is fixed at the position near the end of the cylinder, and the end of the cylinder is detachably connected with an end cover. Unscrew the end cap when charging, and tighten the end cap when not charging. The end cap plays the role of isolating water and has a certain waterproof function. However, the end cap must be removed when charging, and the removed end cap is easy to lose. This operation is very inconvenient, and the waterproof effect is poor

Another example is the flashlight with a waterproof charging device in Chinese patent 200420066855. In its disclosed technical solution, the charging unit is plugged into the main body of the flashlight when charging, so that the transmission point of the charging unit contacts the charging part exposed on the main body of the flashlight and sealed with the main body of the flashlight. After charging, take off the charging unit, because the charging part exposed on the main body of the flashlight is sealed with the main body of the flashlight, so the flashlight has waterproof function; but the charging unit must be installed when charging, so the operation is more troublesome, and Its production cost is relatively high, and it is not convenient to promote and use in large quantities
