[0003] The patent document with the prior art publication number CN219640119U provides a classroom lighting lamp with a lamp tube protection structure. Through the arrangement of a protective strip, a rotating shaft and a limit rod, the utility model arranges a scraper strip, which is arranged on the outside of a transparent outer protective shell. The scraper strip and the transparent outer protective shell are fitted together, and the scraper strip and the transparent outer protective shell can also be slidably connected, so that dust attached to the surface of the transparent outer protective shell can be removed by scraping, thereby cleaning the transparent outer protective shell, so that the light of this classroom lighting lamp will not be blocked; although the lighting lamp has good beneficial effects, the following problems still exist: the lamp tube is prone to internal damage after long-term use or due to power problems. In the classroom lighting lamp with a lamp tube protection structure, the transparent outer protective shell and the mounting box are fixed to the lamp tube by screws. When replacing the lamp tube, a screwdriver suitable for the screws needs to be used, which is relatively troublesome. In view of this, we propose a classroom lighting lamp with a lamp tube protection structure. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Example:

[0025] This embodiment discloses a classroom lighting lamp with a lamp tube protection structure. Figures 1 to 5 , including a lamp holder 1, a lamp tube 2 and a transparent protective cover 3. The lamp tube 2 is arranged at the bottom of the lamp holder 1, and the transparent protective cover 3 is arranged on the surface of the lamp tube 2. Both ends of the transparent protective cover 3 are opposite to the two ends of the bottom of the lamp holder 1. The two mounting mechanisms 4 at the two ends of the bottom of the lamp holder 1 are used to fix the two ends of the transparent protective cover 3 on the two ends of the lamp holder 1.

[0026] Specifically, Figure 3 , Figure 4 As shown, mounting holes 101 are provided on both sides of the opposite ends of the lamp holder 1 and the transparent protective cover 3 for installing the mounting mechanism 4. Through holes 102 connecting the mounting hole 101 and the outside are provided along both ends of the lamp holder 1 to facilitate the movement of the mounting mechanism 4 leading parts. A locking hole 301 is provided at a position of the transparent protective cover 3 relative to the through hole 102 to facilitate the fixation of the transparent protective cover 3.

[0027] Further, such as Figure 3 , Figure 4As shown, the mounting mechanism 4 includes two symmetrically arranged plug rods 401 and a pull plate 402; one end of the plug rod 401 is inserted into the mounting hole 101 and extends to the inside of the lock hole 301, a limiting ring 403 is fixedly sleeved on the middle surface of the plug rod 401, and a spring 404 is sleeved along one side of the limiting ring 403 of the plug rod 401, one end of the spring 404 is fixedly connected to the surface of one side of the limiting ring 403, and the other end of the spring 404 is fixedly connected to the inner wall of one end of the mounting hole 101, and the two plug rods 401 are fixedly connected to the inner wall of one end of the mounting hole 101. The other end of the rod 401 is fixedly connected to the surfaces of both ends of one side of the pull plate 402. When the lamp tube 2 needs to be replaced, the two pull plates 402 of the two mounting mechanisms 4 are pulled toward the two ends of the lamp holder 1 respectively. The pull plate 402 drives the insertion rod 401 to move along the through hole 102 toward the outside of the lamp holder 1, so that one end of the insertion rod 401 is pulled out of the lock hole 301, and at the same time drives the limiting ring 403 to move the compression spring 404 toward one end of the mounting hole 101, so that the transparent protective cover 3 can be removed to replace the lamp tube 2.

[0028] Furthermore, Figure 3 , Figure 4 As shown, a cam 405 is provided between the pull plate 402 and the lamp holder 1, and one end of the cam 405 is rotatably connected to the surface of one side of the lamp holder 1 through the mounting plate and the rotating shaft. After one end of the insertion rod 401 is pulled out from the lock hole 301, the cam 405 is rotated so that the other end of the cam 405 supports the pull plate 402. When the transparent protective cover 3 is installed after the lamp tube 2 is replaced, there is no need to always pull the pull plate 402, which makes it easier to install the transparent protective cover 3.

[0029] It is worth noting that if Figure 5 As shown, T-slots 103 are provided at the bottom of both sides of the opposite side of the lamp holder 1 and the transparent shield 3, and a T-shaped plug 302 is provided along the bottom of the lock hole 301 at a position of the transparent shield 3 relative to the T-slot 103. The T-slot 103 and the T-shaped plug 302 have a guiding function. When the transparent shield 3 is installed, the through hole 102 can be aligned with the lock hole 301 along the T-slot 103 and the T-shaped plug 302, so that one end of the insertion rod 401 is conveniently inserted into the lock hole 301.

[0030] It is worth noting that Figure 3 , Figure 4 As shown, the insertion rod 401 is rounded, the surface of the insertion rod 401 is connected to the inner wall of the through hole 102, the length of the insertion rod 401 extending into the lock hole 301 is no greater than the length of the cam 405, and when the other end of the cam 405 presses the pull plate 402, it keeps one end of the insertion rod 401 completely away from the lock hole 301.

[0031] Working principle: When the lamp tube 2 needs to be replaced, the two pull plates 402 of the two mounting mechanisms 4 are pulled toward the two ends of the lamp holder 1 respectively, and the pull plate 402 drives the insertion rod 401 to move along the through hole 102 toward the outside of the lamp holder 1, so that one end of the insertion rod 401 is pulled out of the lock hole 301, and at the same time drives the limiting ring 403 to move the compression spring 404 toward one end of the mounting hole 101, and rotates the cam 405 so that the other end of the cam 405 presses the pull plate 402, and the transparent protective cover 3 can be removed along the T-shaped slot 103 and the T-shaped plug block 302, and the lamp tube 2 can be replaced; after replacement, the through hole 102 can be aligned with the lock hole 301 along the T-shaped slot 103 and the T-shaped plug block 302, and the cam 405 is rotated downward, and the cam 405 is separated from the pull plate 402. Due to the action of the spring 404, the insertion rod 401 is inserted into the lock hole 301 through the limiting ring 403 to fix the transparent protective cover 3.

[0032] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
