Description

Technical Field

[0001] The utility model relates to a lighting appliance, and more specifically, to an integrated waterproof flashlight. Background Art

[0002] Among the flashlights on the current market, in most products, the flashlight lamp and the tail end cap are connected to the flashlight body by means of screw rotation, and the joints are exposed on the surface of the flashlight body, resulting in poor waterproof effect, and it is easier for the metal flashlight body to rust and the battery to rot. There are also flashlight bodies made of plastic, but often rivets are used for connecting the housing or accessories, and the waterproof effect is also affected. The utility model patent with the publication number of CN206846390U discloses a new type of flashlight, but its lamp body and lamp head are also connected by threads, and the joints are exposed, so there is also the problem of poor waterproof effect as described above. Content of the Utility Model

[0003] In the existing flashlights, due to the presence of component connection joints on the surface, the waterproof effect is affected, and problems such as rust and rot are likely to occur. To overcome this defect, the utility model provides an integrated waterproof flashlight, which can more effectively improve the waterproof problem.

[0004] The technical solution of the utility model is: an integrated waterproof flashlight, including a housing and a lighting part arranged on the housing, and a battery arranged in the housing.

The connection part between the lighting part and the housing main body is located at the open end of the housing main body, and there are no exposed component joints on the surface of the housing main body that can cause water to enter the interior of the housing, eliminating the possibility of water leakage at the joints.

[0005] Preferably, there are two open ends of the housing main body and they are opposite in position. A tail cap assembly is provided at the open end opposite to the end where the lighting part is located. A front end fixing part and a tail end fixing part are respectively provided at both ends of the bracket. The lighting part and the tail cap assembly are respectively connected to the front end fixing part and the tail end fixing part in a one-to-one correspondence, and the lighting part and the tail cap assembly respectively abut against the ports of the corresponding open ends of the housing main body. The setting of the tail cap assembly increases the access channels of the flashlight, facilitating the replacement of the battery and the disassembly and assembly of the internal devices of the housing during maintenance. The lighting part and the tail cap assembly are connected to both ends of the bracket, and at the same time, they respectively abut against the two ends of the housing main body.

Compared with the threaded-mounted tail cap assembly, the volume of the tail cap assembly can be reduced in this technical solution.

[0007] Preferably, the lighting part includes a front cover. The front cover is snap-connected to the front end fixing portion and abuts against the open end port of the housing body where the lighting part is located. The setting of the front cover enables the lighting part to abut against the open end port of the housing body, so that the lighting part and the tail cap assembly are mutually constrained by the bracket and are axially limited by the housing body at the same time, finally realizing the fixation of the lighting part on the housing.

[0008] Preferably, the bracket is provided with a circuit component cavity, and the battery is tightly fitted and installed in the circuit component cavity. The bracket is the installation carrier for internal parts such as the battery and electronic components. The bracket with a circuit component cavity can more stably and reliably accommodate and install parts such as the battery and electronic components.

[0009] Preferably, a circuit board assembly is further provided in the circuit component cavity. A charging port exposed on the surface of the housing body is connected to the circuit board assembly. The circuit board assembly can improve the circuit integration degree on the flashlight. This integrated waterproof flashlight can be charged, reducing the trouble of frequently replacing the battery.

[0010] Preferably, the housing body is covered with a soft rubber sleeve. The soft rubber sleeve can provide good protection for the housing body.

[0011] Preferably, the housing body is a cylindrical body with an oval cross-section. The non-cylindrical housing body will not roll when placed flat and is more comfortable to carry around.

[0012] Preferably, a belt clip is further provided on the housing body. The setting of the belt clip facilitates attaching the flashlight to the waistband for convenient carrying.

[0013] Preferably, the housing body is made of an aluminum alloy part. The housing body made of aluminum alloy not only has a better texture but also has better drop and knock resistance performance.

[0014] The beneficial effects of the present utility model are:
