[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-4 shown, a universal protective lamp socket with bayonet and screw threads of the present utility model has telescopic tubes 101 fixedly connected to the left and right side walls of the inner cavity of the mounting base 100. The telescopic tubes 101 facilitate the limiting and guiding of the movement of the telescopic rods 102. The inner walls of the telescopic tubes 101 are fixedly connected with telescopic rods 102, which facilitate the support of the fastening seats 103. The opposite ends of the two groups of telescopic rods 102 are fixedly connected with fastening seats 103, which facilitate the installation and connection of the light bulbs. Thread grooves are provided on the inner walls of the fastening seats 103 for installing screw-thread light bulbs. Card slots are provided on the front and rear side walls of the fastening seats 103 for installing bayonet light bulbs. The lower sides of the opposite side walls of the two groups of fastening seats 103 are inclined. Chutes are provided on the left and right sides of the outer wall of the mounting base 100, and lifting frames 104 are slidably connected to the inner walls of the chutes. The lifting frames 104 facilitate the lifting of the limiting rings 105. The limiting rings 105 are fixedly connected to the inner walls of the lifting frames 104, which facilitate the limiting of the fastening seats 103. The outer walls of the fastening seats 103 are inclined.

[0022] In this embodiment: The mounting base 100 is installed on the wall at the designated position through expansion screws. When installing a screw-thread light bulb, the screw-thread light bulb is screwed onto the thread groove to electrically connect the mounting base 100 and the screw-thread light bulb for power supply. When installing a bayonet light bulb, first push the lifting frame 104 upward to drive the limiting ring 105 to move, so that the limiting ring 105 releases the limit on the fastening seat 103. Then push the bayonet light bulb to push the two groups of fastening seats 103, so that the bayonet light bulb is pushed to the card slot. By pulling the lifting frame 104 to drive the limiting ring 105 to move downward for reset, the movement of the limiting ring 105 is used to push the two groups of fastening seats 103 to move for reset, which enables the device to facilitate the installation and connection of bayonet or screw-thread light bulbs, realizing the interchangeable installation of light bulbs with different interfaces and being beneficial to improving the practicability of the device.

[0023] A fixing ring 106 is fixedly connected to the inner wall of the mounting base 100, which facilitates the support of the pushing spring 107. The bottom wall of the fixing ring 106 is fixedly connected with a pushing spring 107, and the bottom end of the pushing spring 107 is fixedly connected to the top wall of the lifting frame 104.

[0024] In this embodiment: When the lifting frame 104 moves downward and resets, the pushing spring 107 is used to push the lifting frame 104 downward for reset. The lifting frame 104 drives the limit ring 105 to move. The downward movement of the limit ring 105 squeezes the fastening seat 103, facilitating the connection of the bulb by the fastening seat 103, which is conducive to quickly installing the bulb and improving the connection rate of the device.

[0025] A silica gel ring 108 is fixedly connected to the bottom wall of the limit ring 105. The silica gel ring 108 is convenient for fitting on the outer wall of the bulb. The silica gel ring 108 is made of heat-resistant silica gel, and the bottom wall of the silica gel ring 108 is inclined.

[0026] In this embodiment: The movement of the limit ring 105 drives the silica gel ring 108 to move. The movement of the silica gel ring 108 makes it abut against the bulb, facilitating the sealing of the connection part, preventing dust and impurities from entering and affecting the electrical connection. At the same time, it limits the screw bulb to prevent the screw bulb from deflecting and loosening, which is conducive to protecting the bulb.

[0027] Moving grooves are evenly formed on the outer wall of the lifting frame 104, and the mounting seat 100 is located in the inner cavity of the moving groove.

[0028] In this embodiment: The formation of the moving grooves facilitates the limiting and guiding of the movement of the lifting frame 104, preventing the lifting frame 104 from shifting, which is conducive to driving the limit ring 105 to move up and down and horizontally.

[0029] Reset springs 109 are fixedly connected to the left and right side walls of the inner cavity of the mounting seat 100. The reset springs 109 facilitate the pushing and reset of the telescopic rod 102. The reset springs 109 are located in the inner cavity of the telescopic tube 101, and the other ends of the reset springs 109 are connected to the telescopic rod 102.

[0030] In this embodiment: The reset springs 109 facilitate the pushing and moving reset of the telescopic rod 102. The telescopic rod 102 drives the fastening seat 103 to move and reset, making it convenient for the fastening seat 103 to clamp the bayonet bulb, preventing the bayonet bulb from loosening and falling, which is conducive to the subsequent fastening installation of the bulb.
