DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to solve the problem that the existing automobile lamp is sealed by pressing and fitting the sealing ring, the stability is poor, the position is easily offset due to shaking and collision, the service life of the sealing structure is shortened, and the problem that it cannot be used stably for a long time, this embodiment provides the following technical solutions:

[0026] A car lampshade with good sealing performance comprises a light-transmitting glass 1, a lampshade frame 3 is arranged at the lower end of the light-transmitting glass 1, and a light-transmitting glass frame 3 is arranged at the lower end of the light-transmitting glass 1. Figure 1 and Figure 2 As shown, after the light bulb for emitting light is placed inside the lampshade frame 3, the upper end of the light bulb is wrapped and protected by the light-transmitting glass 1, and a recessed ring 6 is arranged around the inside of the lampshade frame 3, and an embedded connecting ring 2 is arranged around one end of the light-transmitting glass 1 facing the recessed ring 6, and the outside of the embedded connecting ring 2 is connected to the internal sliding groove of the recessed ring 6, and the light-transmitting glass 1 is inserted into the recessed ring 6 through the embedded connecting ring 2 to achieve preliminary sealing and then wrapping;

[0027] In this embodiment, if Figure 3As shown, a second reserved cavity 8 is provided on one side of the lower end of the inner part of the recessed ring 6, a first reserved cavity 7 is provided on the other side of the lower end of the inner part of the recessed ring 6, a second rubber ring 16 is provided around the inner part of the first reserved cavity 7, and a first rubber ring 9 is provided around the inner part of the second reserved cavity 8. When the embedded connecting ring 2 is embedded in the recessed ring 6 and the sealed installation is completed, the second rubber ring 16 and the first rubber ring 9 in the first reserved cavity 7 and the second reserved cavity 8 can fit the recessed ring 6, and the sealing can be achieved by fitting, so as to prevent the external liquid from passing through the embedded connecting ring 2 and contacting the light bulb installed inside. The embedded connecting ring 2 is fitted by the second rubber ring 16 and the first rubber ring 9 on both sides, so as to limit and prevent the sealing failure caused by shaking. When shaking occurs, the recessed ring 6 first limits the embedded connecting ring 2 to prevent the embedded connecting ring 2 from being displaced due to shaking. On the other hand, the first rubber ring 9 and the second rubber ring 16 made of rubber can continuously fit and maintain the sealing while providing shock absorption capability.

[0028] In this embodiment, connecting blocks 4 are disposed on both sides of the four corners of the light-transmitting glass 1, and the connecting blocks 4 are welded and fixed to the embedded connecting ring 2. Figure 4 , Figure 5 and Figure 6 As shown, a storage cavity 15 is provided inside the connection block 4, and the storage cavity 15 penetrates and extends to the upper and lower ends of the connection block 4. A connecting bolt 11 is provided inside the storage cavity 15. The connecting bolt 11 passes through the storage cavity 15, passes through the connection block 4, and is embedded in the lampshade frame 3 to complete the fixation of the light-transmitting glass 1 and the embedded connecting ring 2. The penetration of the connecting bolt 11 can assist the fixation of the embedded connecting ring 2 and the light-transmitting glass 1. When disassembling and inspecting the internal lamp tube, the light-transmitting glass 1 and the embedded connecting ring 2 can be disassembled as the connecting bolt 11 is rotated and disassembled;

[0029] In this embodiment, a reserved bolt connection hole 10 is provided at the lower end of the storage cavity 15, and the inner wall of the bolt connection hole 10 and the outer wall of the connection bolt 11 are threadedly matched, so that the connection bolt 11 can be rotated and embedded in the bolt connection hole 10 through the threaded match. Figure 4 , Figure 5 and Figure 6 As shown, a limiting surface 12 for limiting the installation depth is provided at the lower end of the storage cavity 15. After the connecting bolt 11 rotates and continues to move longitudinally downward, the connecting bolt 11 stops rotating until the protruding position of the connecting bolt 11 abuts against the limiting surface 12.

[0030] In this embodiment, if Figure 5As shown, an inner gasket 14 is provided between the lower end of the connecting block 4 and the upper end of the lampshade frame 3, and the inner gasket 14 surrounds the outside of the connecting bolt 11, and fills the gap between the connecting block 4 and the lampshade frame 3 through the limiting surface 12, so as to prevent the external liquid from flowing into and contacting the connecting bolt 11 from between the connecting block 4 and the lampshade frame 3, and prevent the connecting bolt 11 from rusting due to contact with the liquid;

[0031] In this embodiment, an outer gasket 5 is provided at the upper end of the outer portion of the connecting block 4. The outer gasket 5 and the inner gasket 14 can be used together to fully wrap and seal the connecting bolt 11, so that the connecting bolt 11 can be protected from erosion by external liquid during installation and use. The outer gasket 5 and the connecting block 4 are connected on both sides by connecting sheets 13. Figure 5 As shown, the connecting piece 13 , the outer gasket 5 and the inner gasket 14 are all made of rubber. Through the connecting piece 13 made of rubber, the outer gasket 5 can be directly opened manually to install and remove the connecting bolts 11 .

[0032] Working principle: When using the device and sealing the internal bulb position, the light-transmitting glass 1 is embedded in the recessed ring 6 reserved inside the lampshade frame 3 by embedding the connecting ring 2. By continuously pressing the light-transmitting glass 1, the inner and outer sides of the recessed ring 6 are respectively in contact with the second rubber ring 16 and the first rubber ring 9. The second rubber ring 16 and the first rubber ring 9 made of rubber can prevent liquid from flowing into the interior and contacting the bulb. The outer gasket 5 is opened, and the connecting bolt 11 passes through the storage cavity 15 and is embedded in the bolt connecting hole 10 with continuous rotation. As the connecting bolt 11 continues to rotate until the protruding position of the connecting bolt 11 fits the upper end of the limiting surface 12, the connecting bolt 11 rotates and drives the inner gasket 14 to move, so that the inner gasket 14 moves between the connecting block 4 and the recessed ring 6 to fill the gap between them.
