Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a blackboard lamp that is easy to install and disassemble. A blackboard light that is easy to assemble and disassemble includes a light body and two hanging rods detachably connected to the upper side of the light body. The upper side of the light body has a recessed groove along its length. A first slider and a second slider are slidably disposed in the groove. The inner sides of the first slider and the second slider are each recessed with a first slot. A locking block that can cooperate with the first slot is provided at the lower end of the two hanging rods. A connecting rod is provided between the first slider and the second slider. One end of the connecting rod is rotatably connected to one side of the first slider, and a hook is provided at the other end of the connecting rod. A connecting shaft that can engage with the hook is protruding from one side of the second slider.

[0004] In one embodiment, the connecting shaft is provided with a limiting member that can limit the movement of the connecting rod so that the hook remains connected to the connecting shaft.

[0005] In one embodiment, the limiting member includes a limiting ring that is threaded onto one side of the connecting shaft. One side of the hook portion has an annular groove recessed with the center line of the connecting shaft as the center. One end of the limiting ring can extend into the annular groove along the thread of the connecting shaft.

[0006] In one embodiment, the outer periphery of the limiting ring is provided with anti-slip texture.

[0007] In one embodiment, both the first slider and the second slider have a notch that communicates with the first slot on their upper sides, and the hanging rod can be fitted into the notch.

[0008] In one embodiment, the hook and the connecting shaft are magnetically attracted to each other to maintain a hook-and-loop engagement.

[0009] In one embodiment, the first slider is fixed to the lamp body by screws, the second slider can move relatively closer to or further away from the first slider along the slide groove, and the maximum stroke between the second slider and the first slider is greater than the distance between the two suspension rods.

[0010] In summary, the advantages of this utility model over the prior art are: This utility model utilizes the sliding groove of the lamp body and the sliding cooperation of the first and second sliders to ensure that the locking blocks of the hanging rod are respectively engaged with the first locking groove. Combined with the hooking design of the connecting rod hook and the connecting shaft, the assembly and disassembly of the lamp body and the hanging rod can be completed without complicated tools.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 5 The present invention preferably provides a blackboard lamp that is easy to assemble and disassemble, including a lamp body 1 and two hanging rods 2 detachably connected to the upper side of the lamp body 1. The upper side of the lamp body 1 has a groove 3 recessed along its length. A first slider 4 and a second slider 5 are slidably disposed in the groove 3. The inner sides of the first slider 4 and the second slider 5 are respectively recessed with a first slot 6. A locking block 7 that can cooperate with the first slot 6 is provided at the lower end of the two hanging rods 2. A connecting rod 8 is provided between the first slider 4 and the second slider 5. One end of the connecting rod 8 is rotatably connected to one side of the first slider 4, and a hook 9 is provided at the other end of the connecting rod 8. A connecting shaft 10 that can hook and cooperate with the hook 9 is protruding from one side of the second slider 5.

[0017] Specifically, the first and second sliders are pre-embedded in the grooves on the upper side of the lamp body and slid along the grooves to the preset installation distance. Then, the locking blocks at the lower ends of the two suspension rods are aligned with the first locking slots of the first and second sliders, respectively. Force is applied to make the locking blocks on the two suspension rods engage with the first locking slots one by one, thus achieving initial fixation between the suspension rods and the corresponding sliders. Finally, the connecting rod (one end of which is rotatably connected to the first slider) is rotated so that the hook at the other end of the connecting rod is aligned with the connecting shaft of the second slider. The connecting rod is pushed so that the hook engages with the connecting shaft. The two sliders are linked and limited by the connecting rod. Furthermore, the two relatively set first locking slots and corresponding locking blocks effectively prevent the first and second sliders from sliding freely along the grooves, thus completing the assembly of the suspension rods and the lamp body.

[0018] When disassembly is required, push the connecting rod in the opposite direction to disengage the hook from the connecting shaft, thereby releasing the linkage restriction between the two sliders. At this time, the user can slide the second slider to disengage the locking block from the first slot, thus completing the disassembly.

[0019] Furthermore, the connecting shaft 10 is provided with a limiting member 11 that can limit the movement of the connecting rod 8 so that the hook 9 remains connected to the connecting shaft 10. Furthermore, the limiting member 11 includes a limiting ring 12 that is threadedly fitted onto one side of the connecting shaft 10, and an annular groove 13 is recessed on one side of the hook 9 with the center line of the connecting shaft 10 as the center. One end of the limiting ring 12 can extend along the thread of the connecting shaft 10 into the annular groove 13.

[0020] Specifically, after the hook and connecting shaft are engaged, the limiting ring and connecting shaft are connected by a threaded connection. When the limiting ring is rotated, it will move towards the connecting rod along the axis of the connecting shaft. Continue rotating the limiting ring until one end extends into the annular groove on the connecting rod centered on the center line of the connecting shaft. At this point, the inner wall of the annular groove forms a circumferential limit on the limiting ring, thereby preventing the relative rotation of the connecting rod and the connecting shaft. Structurally, this restricts the hook from detaching from the connecting shaft. At the same time, the self-locking characteristic of the threaded connection prevents the limiting ring from loosening on its own, achieving reliable locking of the connecting rod's rotation and ensuring the long-term stability of the hook structure.

[0021] Furthermore, the outer periphery of the limiting ring 12 is provided with anti-slip texture.

[0022] Specifically, the anti-slip texture set along the circumference of the outer periphery of the limit ring has the core function of increasing the friction between the operator's hand and the surface of the limit ring, reducing slippage when rotating the limit ring; by improving the effectiveness of hand grip and force application, the operator can rotate the limit ring more effortlessly and quickly to complete the locking or unlocking operation of the limit ring, thus improving the convenience of overall assembly and disassembly.

[0023] Furthermore, both the first slider 4 and the second slider 5 have notches 14 that are connected to the first slot 6 through their upper sides, and the hanging rod 2 can be fitted into the notches 14.

[0024] Specifically, the notches on the upper sides of the first and second sliders are connected to the first slot. When the locking block at the lower end of the rod is engaged in the first slot, the rod body can be simultaneously fitted into the notch. The inner wall of the notch fits tightly against the outer wall of the rod, forming a radial limit on the rod. Through the dual cooperation of "slot engagement + notch fitting", the compactness and stability of the connection between the rod and the slider are further improved.

[0025] Furthermore, the hook 9 and the connecting shaft 10 are magnetically attracted to each other to maintain a hook-and-loop engagement.

[0026] Specifically, at least one of the hook and the connecting shaft is equipped with a magnetic component (such as a magnet embedded in the inside of the hook or the connecting shaft being made of magnetic material). When the connecting rod drives the hook to approach the connecting shaft, the magnetic attraction force generated by the magnetic component will guide the hook to accurately align with the connecting shaft, reducing the difficulty of alignment during assembly and assisting the hook to quickly complete the hooking. After the hooking is completed, the magnetic attraction force continues to act between the hook and the connecting shaft, forming a double fixation of "hooking + magnetic attraction", further restricting the rotation of the connecting rod, preventing the hook from loosening due to slight vibration or external force, and strengthening the stability of the hooking structure.

[0027] Furthermore, the first slider 4 is fixed to the lamp body 1 with screws, and the second slider 5 can move relatively closer to or further away from the first slider 4 along the slide groove 3, and the maximum stroke between the second slider 5 and the first slider 4 is greater than the distance between the two suspension rods 2. Specifically, the first slider is fixed to the lamp body with screws, providing a fixed reference point for the installation of the suspension rods and preventing the first slider from sliding arbitrarily along the slide groove. During disassembly, it is only necessary to first slide the second slider to the right to disengage it from the corresponding suspension rod's locking block, and then hold the lamp body as a whole and slide it to the left to disengage the first slider from the corresponding suspension rod's locking block, thereby achieving the disassembly and removal of the lamp body.
