The first waterproof part 521 is released, and the second waterproof part 522 has good elasticity, so that the restoration is completed under the action of the elasticity. The second waterproof portion 522 does not separate from the first waterproof portion 521 throughout the elastic movement to maintain the sealing of the window 14 together with the first waterproof portion 521.

The first waterproof member 52 is capable of triggering the key 51 while sealing the window 14 by the provision of the first waterproof portion 521 and the second waterproof portion 522. The first waterproof part 521 and the second waterproof part 522 have simple matching structures, do not need complex triggering and sealing structures, and simplify the processing technology of the lamp.

In one embodiment of the present utility model, the first waterproof portion 521 and the second waterproof portion 522 are integrally formed. The integrated forming processing mode is simpler, processes such as pasting and welding are not needed, and manpower and material resources are saved.

Alternatively, in other embodiments, the first waterproof portion 521 and the second waterproof portion 522 may be connected by bonding or the like.

In one embodiment of the present utility model, referring to fig. 4 and 5, the second waterproof portion 522 is bent and extended from the first waterproof portion 521 toward an end far from the first waterproof portion 521.

The latch 62 has a first fixing hole 621, and the pressing piece 61 has a second fixing hole 611. The first waterproof portion 521 sequentially penetrates through the second fixing hole 611 and the first fixing hole 621, so that the abutting portion 5221 of the second waterproof portion 522 abuts against a side of the pressing piece 61 opposite to the latch 62. Such a securing structure 60 facilitates mounting and securing the second flashing 522 while also facilitating securing the second flashing 522 to the lamp envelope 10 to seal the window 14.

Through the above scheme, the contact area between the second waterproof part 522 and the shell is increased, which is beneficial to improving the sealing effect between the second waterproof part 522 and the lamp housing 10. Meanwhile, the bending and extending design is adopted to increase the elasticity of the second waterproof part 522, so that the resetting effect of the second waterproof part 522 away from the key 51 is improved.

In one embodiment of the present utility model, referring to fig. 3 to 5, a side of the second waterproof portion 522 facing away from the key 51 is recessed to form a second groove 5222.

The limiting portion 532 is disposed in the mounting cavity 13 and is used for abutting against the lamp housing 10.

Specifically, the shape and size of the body portion 531 is adapted to the shape and size of the window 14 to facilitate movement of the body portion 531 within the window 14.

In one embodiment, the main body 531 is recessed toward one side of the first waterproof member 52 to form a receiving groove 5331, and the first waterproof member 52 is received in the receiving groove 5331 and connected to the main body 531 by means of a snap fit, an adhesive, or the like. When a force is applied to the main body 531, the main body 531 moves to drive the first waterproof member 52 connected thereto to move.

The limiting portion 532 is disposed inside the mounting cavity 13, one end of the limiting portion 532 is connected to the main body portion 531, the other end of the limiting portion extends towards one side facing away from the main body portion 531, and the limiting portion 532 can be clamped to the inner wall of the lamp housing 10 on the outer periphery side of the window 14, so that the first waterproof portion 521 is limited by the resetting stroke of the key 51 away from the key.

When the main body 531 is biased, the limiting portion 532 is separated from the inner wall of the lamp housing 10 until the first waterproof member 52 moves to trigger the key 51. The main body 531 is released, and under the elastic action of the second waterproof member, the first waterproof member 52 resets along with the main body 531 until the limiting portion 532 abuts against the inner wall of the lamp housing 10, so that the resetting stroke of the first waterproof portion 521 away from the key 51 is limited.
