[0030] The upper end of the mounting ring 9 is recessed inward to form a mounting chamber 12 , in which a push ring 13 is movably disposed, and the second sealing ring 10 is disposed at the upper end of the push ring 13 .
[0031] In this embodiment, when the lampshade 2 is installed on the back cover 1, the first sealing ring 8 is arranged between the supporting ring 4 and the shielding ring 7, so as to perform the first sealing between the lampshade 2 and the back cover 1, and the second sealing ring 10 is arranged between the mounting ring 9 and the mating ring 11, so as to perform the second sealing between the lampshade 2 and the back cover 1. At the same time, the second sealing ring 10 will receive a thrust from the direction of the mounting ring 9, so that the second sealing ring 10 is tightly connected with the mating ring 11, thereby improving the sealing effect between the lampshade 2 and the back cover 1.
[0032] More specifically, the lampshade 2 and the back cover 1 can be double-sealed by the first sealing ring 8 and the second sealing ring 10. When the first sealing ring 8 and the second sealing ring 10 need to be replaced, the lampshade 2 is opened, and the first sealing ring 8 is directly exposed outside the back cover 1. The first sealing ring 8 can be pulled to deform so as to be removed for replacement. The push ring 13 is pushed upward, so that the push ring 13 moves along the limiting groove 17, and the push ring drives the second sealing ring 10 to move upward, so as to be exposed from the installation chamber 12.
[0033] See also Figure 1-5 As an implementation method for replacing the second sealing ring 10: a plurality of L-shaped fixing blocks 14 are fixedly provided at the lower end of the second sealing ring 10, a plurality of fixing grooves 15 matching with the fixing blocks 14 are provided on the pushing ring 13, a plurality of springs 16 are fixedly provided in each of the installation chambers 12, and both ends of the springs 16 are fixedly connected with the installation chamber 12 and the pushing ring 13 respectively, and a limiting groove 17 matching with the pushing ring 13 is provided in the installation chamber 12.
[0034] Specifically, when the lamp cover 2 is opened, the matching ring 11 is separated from the mounting ring 9, and under the push of the spring 16, the pushing ring 13 moves upward along the limiting groove 17, and the pushing ring 13 drives multiple fixing blocks 14 to move upward, and the fixing blocks 14 drive the second sealing ring 10 to move upward, thereby exposing the second sealing ring 10 from the upper end of the mounting chamber 12, and rotating the second sealing ring 10 so that the lower end of the second sealing ring 10 rotates in the mounting chamber 12, and the second sealing ring 10 drives the fixing block 14 to rotate, so that the fixing block 14 moves in the limiting groove 17 and releases the clamping connection with the limiting groove 17, and at this time, the second sealing ring 10 is pulled upward, so that the second sealing ring 10 drives the fixing block 14 to move out of the limiting groove 17, thereby removing it.
[0035] See also Figure 1-5As an implementation method for installing the lampshade 2: each of the clamping blocks 5 is provided with a first inclined surface 18, the clamping ring 6 is provided with a second inclined surface 19 matched with the clamping block 5, and a moisture-absorbing pad 20 is fixedly provided in the matching ring 11.
[0036] Specifically, the lampshade 2 drives the support ring 4 to move, and the support ring 4 drives the clamping block 5 to move, and the lampshade 2 is placed on the back cover 1, so that the first inclined surface 18 of the clamping block 5 and the second inclined surface 19 of the clamping ring 6 are in contact, and the lampshade 2 is pressed in the direction of the back cover 1. Under the push of the second inclined surface 19, the clamping block 5 and the support ring 4 are slightly deformed, so that the clamping block 5 moves to the lower end of the shielding ring 7, so that the lampshade 2 is installed on the back cover 1. When the lampshade 2 needs to be removed, the support ring 4 near the two fixing blocks 14 is pulled outward, so that the support ring 4 is slightly deformed, so that the lampshade 2 can be removed. The moisture-absorbing pad 20 adopts a new type of Co-SHM film, which can effectively absorb water vapor that accidentally enters the lampshade 2.
[0037] To sum up, when the overall equipment is in use:
[0038] When the lampshade 2 needs to be installed on the back cover 1, the lampshade 2 drives the support ring 4 to move, and the support ring 4 drives the clamping block 5 to move, and the clamping block 5 is placed on the back cover 1, so that the first inclined surface 18 of the clamping block 5 and the second inclined surface 19 of the clamping ring 6 are in contact, and the lampshade 2 is pressed toward the back cover 1. Under the push of the second inclined surface 19, the clamping block 5 and the support ring 4 are slightly deformed, so that the clamping block 5 moves to the lower end of the shielding ring 7, so that the lampshade 2 is installed on the back cover 1. When the lampshade 2 needs to be removed, the support ring 4 near the two fixing blocks 14 is pulled outward, so that the support ring 4 is slightly deformed, so that the lampshade 2 can be removed.
[0039] When the lampshade 2 and the back cover 1 are sealed, the first sealing ring 8 is arranged between the support ring 4 and the shielding ring 7, so as to perform the first sealing between the lampshade 2 and the back cover 1, and the second sealing ring 10 is arranged between the mounting ring 9 and the matching ring 11, so as to perform the second sealing between the lampshade 2 and the back cover 1. At the same time, under the push of the spring 16, the pushing ring 13 moves along the limiting groove 17, and the pushing ring drives the second sealing ring 10 to move, so that the second sealing ring 10 is tightly connected with the matching ring 11. The first sealing ring 8 and the second sealing ring 10 can perform a double-layer sealing between the lampshade 2 and the back cover 1, thereby improving the sealing effect between the lampshade 2 and the back cover 1. The moisture-absorbing pad 20 adopts a new Co-SHM film, which can effectively absorb water vapor accidentally entering the lampshade 2.
[0040] When the first sealing ring 8 and the second sealing ring 10 need to be disassembled and replaced, the lamp cover 2 is opened, and the first sealing ring 8 is directly exposed outside the back cover 1. The first sealing ring 8 can be pulled to deform it so that it can be disassembled and replaced. When the lampshade 2 is opened, the matching ring 11 is separated from the mounting ring 9, and the pushing ring 13 is moved upward along the limiting groove 17 under the push of the spring 16, and the pushing ring 13 drives multiple fixing blocks 14 to move upward, and the fixing blocks 14 drive the second sealing ring 10 to move upward, thereby exposing the second sealing ring 10 from the upper end of the mounting chamber 12, and rotating the second sealing ring 10 so that the lower end of the second sealing ring 10 rotates in the mounting chamber 12, and the second sealing ring 10 drives the fixing blocks 14 to rotate, so that the fixing blocks 14 move in the limiting groove 17 and release the clamping connection with the limiting groove 17, and at this time, the second sealing ring 10 is pulled upward, so that the second sealing ring 10 drives the fixing blocks 14 to move out of the limiting groove 17, thereby removing it.
