Description

Lead Acid Battery Flashlight

[technical field]

The utility model relates to a flashlight, in particular to a lead-acid battery flashlight.

[Background technique]

At present, the lead-acid battery flashlight generally installs the lead-acid battery in the flashlight, and charges the lead-acid battery through the charging plug on the flashlight. Such a design is not convenient for replacement and maintenance. After a period of use, the lead-acid battery on the flashlight has low storage power and is difficult to charge. Users cannot replace the lead-acid battery with a new one. They can only choose to put the flashlight on hold or discard it, and then buy a new flashlight, resulting in a waste of resources.

[utility model content]

The utility model overcomes the above-mentioned technical deficiencies, and provides a flashlight with simple structure and convenient replacement of the lead-acid battery after the battery is used up.

In order to achieve the above object, the utility model adopts the following technical solutions:

The lead-acid battery flashlight includes a housing, the front end of the housing is provided with a lamp cap assembly, and a battery cavity is arranged in the housing, and it is characterized in that a removable lead-acid battery is placed in the battery cavity, and the positive and negative poles of the lead-acid battery Wires are respectively welded on the metal heads, and the other ends of the two wires are respectively connected to a plug, and a socket that can be matched with the above-mentioned plug is also provided in the housing, and the socket is connected to the light bulb on the lamp head assembly through wires;

A circuit board and a charging plug connected to the circuit board are also arranged in the housing;

A switch is arranged on the circuit board, and the front end of the switch protrudes from the outer surface of the housing;

The connecting ends of the two wires and the positive and negative metal heads are wrapped and sealed with solder;

The housing is equipped with a cover for sealing the battery cavity, and the cover is clamped or hinged on the housing.

The beneficial effects of the utility model are:

1. The positive and negative metal heads of the lead-acid battery are welded with wires respectively, and the other ends of the two wires are respectively connected to a plug. There is also a socket that can be matched with the plug in the housing, so that they can be connected by plugging and easy to replace;

2. When replacing, first open the cover and pull out the plug from the socket, then take it out together with the lead-acid battery, then put a new lead-acid battery and plug in and plug it in, it is easy to replace.

[Detailed ways]

As shown in the figure, the lead-acid battery flashlight includes a housing 1, the front end of the housing 1 is provided with a lamp head assembly 12, and the housing 1 is provided with a battery cavity 11, a circuit board 13 and a charging plug 8 connected to the circuit board 13, A switch 14 is arranged on the circuit board 13 , and the front end of the switch 14 protrudes from the outer surface of the casing 1 .

A removable lead-acid battery 3 is placed in the battery cavity 11, a cover 4 for sealing the battery cavity 11 is clamped on the housing 1, and wires 5 are respectively welded on the positive and negative metal heads of the lead-acid battery 3. so that the connecting ends of the two wires 5 and the positive and negative metal heads are wrapped and sealed with solder 9, and the other ends of the two wires 5 are respectively connected to a plug 6, and the housing 1 is also provided with a socket 7 that can be matched with the plug 6, The socket 7 is connected with the light bulb on the lamp cap assembly 12 through wires. When replacing, first open the face cover 4 and take out the plug 6 together with the lead-acid battery 3 after being pulled out from the socket 7, then put the new lead-acid battery 3 and the plug 6 into and insert them, which is convenient for replacement. In addition to being clamped on the housing 1 , the cover 4 (not shown in the figure) can also be flexibly hinged on the housing 1 .

In the utility model, when the lead-acid battery 3 needs to be replaced, the user first separates the cover 4 from the upper case 21, then pulls out the plug 6 from the socket 7 and takes it out together with the lead-acid battery 3, and then replaces the new lead-acid battery. The battery 3 and the plug 6 are installed and plugged in, and finally the cover 4 is placed and pushed in the reverse direction to engage with the upper case 21, and at the same time the slider 15 is reset and inserted into the clamping hole on the cover 4 under the action of the return spring 16 The replacement is completed within 45 minutes, and the operation is convenient.
