DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1

[0021] A lampshade that is easy to disassemble, referring to Figure 1-Figure 5, including a lower lampshade 1, an upper lampshade 2 and a card block 3, the upper lampshade 2 and the lower lampshade 1 are assembled with each other, the four sides of the lower lampshade 1 are slidably connected with the card blocks 3, the top of each card block 3 is fixedly connected with the lower lampshade 1, the side of the lower lampshade 1 close to the card block 3 is movably connected with the limit bead 32, each limit bead 32 is fixedly connected with a limit rod 33, the four sides of the upper lampshade 2 are provided with card grooves 34 matched with the card blocks 3, the surfaces of the card block 3 and the card groove 34 matched with each other are inclined, each card block 3 is provided with a guide groove 35 matched with the limit rod 33, the end of the limit rod 33 is bent toward the card block 3 and matched with the guide groove 35, a guide block 36 is fixedly connected in the guide groove 35, the side of the guide block 36 away from the limit rod 33 is an inclined surface, and each card block 3 is provided with a card position component for fixing the upper lampshade 2.

[0022] The guide groove 35 includes a slideway 1, a slideway 2, a slideway 3, a slideway 4 and a slideway 5. The slideway 1, the slideway 2, the slideway 3, the slideway 4 and the slideway 5 are arranged clockwise in sequence and are interconnected. The slideway 1 is connected to the slideway 5.

[0023] The locking assembly includes a spring piece 4, and each of the opposing sides of the locking block 3 is provided with a receiving groove 41. The spring piece 4 is fixed in the receiving groove 41. The locking groove 34 is provided with a limiting groove corresponding to the spring piece 4. The spring piece 4 is inserted into the limiting groove to fix the upper lampshade 2.

[0024] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 , and further includes a positioning column 5, which is fixed to the diagonal position of the upper lampshade 2, and a positioning hole 51 that cooperates with the positioning column 5 is opened on the lower lampshade 1.

[0025] When assembling the upper lampshade 2 and the lower lampshade 1, the upper lampshade 2 and the lower lampshade 1 are aligned and assembled by matching the positioning posts 5 with the positioning holes 51 one by one. At the same time, the card slot 34 pushes the card block 3 to move upward, the spring 31 is compressed, and the limiting rod 33 moves downward relative to the card block 3, so that the limiting rod 33 moves in the guide slot 35. Under the obstruction of the guide block 36, the limiting rod 33 enters the slideway 1 and the slideway 2 in turn. After the upper lampshade 2 and the lower lampshade 1 are docked, the end of the limiting rod 33 is stuck in the starting position of the slide 3. At the same time, the card slot 34 squeezes the upper part of the spring piece 4 into the accommodating slot 41. When the limiting slot in the card slot 34 corresponds to the spring piece 4, the upper part of the spring piece 4 is stuck in the limiting slot and pressed against the upper lampshade 2, thereby fixing the lampshade. Then, when the upper lampshade 2 is released, the card slot 34 is stuck under the elastic force of the spring 31. The block 3 moves downward, so that the end of the limit rod 33 enters the sliding three and then is locked in the starting position of the sliding four, thus completing the assembly of the upper lampshade 2 and the lower lampshade 1. When disassembly is needed, the upper lampshade 2 is pressed, and the upper lampshade 2 drives the block 3 and the limit rod 33 to move relative to each other, so that the end of the limit rod 33 enters the sliding three and stops at the starting position of the sliding four in sequence, and then the upper lampshade 2 is released, and then the block 3 is driven to move downward and reset under the resetting action of the spring 31, and the block 3 pushes out the upper lampshade 2, and the upper lampshade 2 can be manually removed. The disassembly is convenient, and the upper lampshade 2 is fixed by the spring piece 4, which not only can fix the upper lampshade 2 and the lower lampshade 1 to each other, but also is convenient for manual separation of the upper lampshade 2 and the lower lampshade 1, and can prevent the upper lampshade 2 from directly falling off when the block 3 is pushed out of the upper lampshade 2.
