Embodiment 1

[0038] refer to figure 1 and figure 2 , is an outdoor light box light-shielding drainage device disclosed by the present invention, including a positioning part 1, the positioning part 1 is made of an injection molded part, and is arranged in a disc shape, the positioning part 1 runs through and detachably connects to the bottom 2 of the outdoor light box, in practice In use, it can generally be installed by casting glue or other convenient disassembly methods.

[0039] The side of the positioning part 1 close to the ground is detachably and fixedly connected with a silicone rubber pad 3. In practical applications, it can generally be fixed by casting rubber or other convenient disassembly methods. The silicone rubber pad 3 is set in the shape of a disc. The side of the pad 3 close to the positioning member 1 is penetratingly provided with a reset bar groove 31 , and the cross section of the reset bar groove 31 is arranged in a V shape or in an arc shape, and is set in a V s...

Embodiment 2

[0045] refer to Figure 4 , is an outdoor light box light-shielding drainage device disclosed in the present invention. The difference from Embodiment 1 is that the positioning member 1 is on the side of the through hole 11 close to the reset bar groove 31 and the side of the reset bar groove 31 close to the through hole 11 A silicon rubber folding layer 4 is provided, and the silicon rubber folding layer 4 isolates the reset bar groove 31 and the through hole 11 .

[0046] The positioning member 1 is provided with extension grooves 13 at both ends of the silicone rubber folded layer 4 , the two ends of the silicone rubber folded layer 4 are extended and inserted into the extension grooves 13 , and the edges of the extension grooves 13 are arranged obliquely along the silicone rubber folded layer 4 .

[0047] The implementation principle of this embodiment is: the staff first installs the silicone rubber pad 3 to the side of the positioning member 1 close to the limit ring 12,...

Embodiment 3

[0049] refer to Figure 5 , is an outdoor light box light-shielding drainage device disclosed in the present invention. The difference from Embodiment 1 is that the end of the silicone rubber pad 3 close to the through hole 11 is detachably provided with a reset rod 5, and the reset rod 5 penetrates through the positioning member 1. The rod 5 is arranged in an inverted T shape. In this embodiment, the vertical section of the reset rod 5 is mounted to the side of the silicone rubber pad 3 close to the positioning member 1 through a threaded connection.

[0050] refer to Figure 5 and Figure 6 , the reset rod 5 sets are provided with a reset spring 6, one end of the reset spring 6 abuts against the side of the positioning part 1 away from the silicone rubber pad 3, and the other end abuts against the side of the horizontal section of the reset rod 5 close to the positioning part 1, and there are 6 sets of return springs A waterproof cover 61 is provided.

Abstract

The invention relates to a light blocking and drainage device for an outdoor light box, which relates to the technical field of lighting equipment. It includes a positioning piece, which runs through and detachably connects to the bottom of the outdoor light box. The side of the positioning piece close to the ground is detachably and fixedly connected with a silicone rubber pad. The side of the silicone rubber pad close to the positioning part is provided with a reset bar groove, and the positioning part is provided with a through hole on one side of the positioning part along the reset bar groove, and the part of the silicone rubber pad at the through hole can cover the through hole, so that the through hole is in the Sealed state, and can rotate along the reset bar groove. In the present invention, through the setting of the silicone rubber pad, the positioning piece, the through hole and the reset bar groove, the rainwater or accumulated water in the light box can be moved along the through hole, and the silicon rubber pad is turned toward the side away from the positioning piece by gravity, so that the rainwater Or when the accumulated water is discharged, when the rain or accumulated water becomes less, the silicone rubber pad will slowly turn around using the rebound memory ability of the silicone rubber; when the rain or accumulated water is drained, the silicone rubber pad will return to its original state.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a light blocking and drainage device for an outdoor light box. Background technique [0002] At present, the light boxes and luminous three-dimensional characters used outdoors have the problem of water accumulation, and rainwater will seep into the interior of the light box during use. The formation of internal water will affect the safety of internal electrical appliances. [0003] The existing drainage method usually uses holes directly at the bottom of the light box, which will affect the overall appearance due to light leakage from the lamps, and even cause mosquitoes to enter the inside of the light box, affecting the environment inside the light box. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an outdoor light box light blocking and drainage device which is convenient for d...
