[0030] Please see Figure 1-3 This utility model provides an easy-to-install classroom blackboard light, comprising:

[0031] Connector 1, with hanger rods 11 fixedly connected to both sides of the lower side wall of connector 1;

[0032] The lifting shell 2 is fixedly installed at the lower end of the two lifting rods 11;

[0033] Mounting sleeve 3 is located below the lifting shell 2, and the mounting sleeve 3 has a guide groove 31 inside;

[0034] Lamp body 4, which is installed inside mounting sleeve 3;

[0035] Limiting mechanism 5 is set in guide groove 31 and is used to limit the lamp body 4;

[0036] Adjustment mechanism 6 is installed inside the hoisting housing 2 and is used to fine adjust the angle of the lamp body 4.

[0037] The above structure enables the lamp body 4 to be separated. During installation, the connector 1 is pre-fixed to the top of the classroom. After the connector 1 is stable, the lamp body 4 is installed. This design makes the installation process simpler and greatly reduces the workload of the installers. The separate design means that when the lamp body 4 needs to be replaced, it does not need to be completely disassembled. Only the lamp body 4 needs to be removed separately, which effectively protects the wall structure. In addition, the angle of the lamp body 4 can be finely adjusted through the adjustment mechanism 6.

[0038] The limiting mechanism 5 includes a groove 51, which is formed on one side wall of the guide groove 31. A wedge 52 is slidably provided in the groove 51. A pull rod 53 is fixedly connected to one side wall of the wedge 52. The other end of the pull rod 53 slides through the groove 51 and extends to the outside of the mounting sleeve 3. A spring 54 is provided between one side wall of the groove 51 and the wedge 52.

[0039] By setting the above structure, the lamp body 4 inserted into the mounting sleeve 3 can be limited to ensure the stability of the lamp body 4 and prevent it from falling out of the mounting sleeve 3.

[0040] The adjusting mechanism 6 includes a rotating rod 61, which is rotatably mounted between the inner walls of both sides of the hoisting housing 2. Two symmetrically distributed slots 62 are opened on the lower side wall of the hoisting housing 2. Two symmetrically distributed adapters 63 are fixedly sleeved on the rotating rod 61. One end of the adapter 63 passes through the slot 62 and is fixedly connected to the mounting sleeve 3. A worm gear 64 is fixedly sleeved in the middle of the rod wall of the rotating rod 61. A worm 65 that meshes with the worm gear 64 is rotatably mounted on one side inner wall of the hoisting housing 2. The other end of the worm 65 passes through the other side wall of the hoisting housing 2 and is fixedly connected to a rotating wheel 66.

[0041] The above structure allows for flexible adjustment of the angle of the lamp body 4, enabling the light to be more accurately projected onto the blackboard in different installation environments, thus improving the lighting effect.

[0042] The top wall of the lamp body 4 is fixedly connected to a guide rail 41.

[0043] The guide rail 41 has a limiting groove 42 on one side wall that is adapted to the wedge block 52.

[0044] The guide rail 41 and the guide groove 31 form a sliding fit.

[0045] It should be noted that this utility model is an easy-to-install classroom blackboard light. In use, the connector 1 is fixed to the classroom ceiling with expansion bolts. Since the lamp body 4 is not installed, the labor intensity of installing the connector 1 is reduced. After installing the connector 1, the guide rail 41 on the lamp body 4 is inserted into the guide groove 31 on the mounting sleeve 3. When the guide rail 41 is inserted into the guide groove 31, it contacts the wedge 52. The inclined surface of the wedge 52 is compressed, causing the wedge 52 to retract into the groove 51 and compress the spring 54, continuing to push the lamp body 4, causing the guide rail 41 to slide along the guide groove 31. When the limiting groove 42 on the guide rail 41 aligns with the groove 51, the wedge 52 loses its compression and is pushed into the limiting groove 42 by the spring 54, limiting the lamp body 4 and preventing... The lamp body 4 slides out of the mounting sleeve 3, and then the rotating wheel 66 drives the worm gear 65 to rotate. The rotation of the worm gear 65 causes the worm wheel 64 to drive the rotating rod 61 to rotate. The rotation of the rotating rod 61 drives the two adapters 63 to rotate, so that the adapters 63 drive the mounting sleeve 3 to rotate around the rotating rod 61 as the axis, thereby adjusting the angle of the lamp body 4 so that the light can be more accurately illuminating the blackboard. Relying on the self-locking property of the worm wheel 64 and the worm gear 65, it can be ensured that the lamp body 4 will not easily change after the angle is adjusted, thus maintaining the stability of the lamp body 4. At this point, the installation is complete. When the lamp body 4 is damaged and needs to be replaced, pull the pull rod 53 to drive the wedge block 52 to disengage from the limiting groove 42 and retract into the groove 51. After the wedge block 52 is no longer limiting, the lamp body 4 can be pulled out from the mounting sleeve 3 for replacement.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
