Specific embodiments

[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0030] Please refer to Figures 1-8 The utility model provides a technical scheme:

[0031] Embodiment one:

[0032] As Figures 1-3As shown, an LED ceiling lamp cover mainly consists of a lamp cover body 1 and a lamp holder 2. The lamp holder 2 is provided with a plurality of mounting holes 18, through which screws or other fasteners can be used to firmly mount the lamp holder 2 on the ceiling. The LED lamp panel 3 is fixedly arranged on the lamp holder 2 to provide lighting for the entire space.

[0033] The lamp cover body 1 and the lamp holder 2 are connected by a plurality of magnetic buckle assemblies. The magnetic buckle assembly includes a connecting column 4 fixedly arranged on the lamp cover body 1 and a sleeve 6 fixedly arranged on the lamp holder 2. The connecting column 4 and the lamp cover body 1 are integrally formed. The sleeve 6 and the lamp holder 2 are also integrally formed, so that they will not easily loosen or fall off during use.

[0034] One end of the connecting column 4 is fixedly provided with a tapered buckle 5, and the large end diameter of the tapered buckle 5 is larger than the diameter of the connecting column 4. The sleeve 6 is provided with a plurality of sliding cavities 7, and the direction of the sliding cavity 7 is perpendicular to the direction of the cavity of the sleeve 6. The sliding cavity 7 is slidably provided with a positioning pin 8. One end of the positioning pin 8 is fixedly provided with a limiting plate 9 to prevent the positioning pin 8 from sliding out of the sliding cavity 7. The end of the positioning pin 8 close to the center of the sleeve 6 is fixedly provided with a wedge-shaped positioning block 10, and the wedge surface of the positioning block 10 faces downward. The positioning pin 8, the limiting plate 9 and the positioning block 10 are integrally formed to improve their stability.

[0035] In addition, a spring is sleeved on the positioning pin 8, and the spring is arranged between the side wall of the sliding cavity 7 and the positioning block 10. The two ends of the spring can be in contact with the side wall of the sliding cavity 7 and the positioning block 10, respectively.

[0036] The tapered buckle 5 in the magnetic buckle assembly is made of ferromagnetic material, and the sleeve 6 is fixedly provided with a positioning ring 11, which is integrally formed with the sleeve 6. The positioning ring 11 is slidably provided with a connecting pin 12, one end of which is fixedly provided with a limiting block 13 to prevent the connecting pin 12 from falling out of the sleeve 6, and the other end of the connecting pin 12 is fixedly provided with a magnet 14. The connecting pin 12 and the magnet 14 can be fixed by glue, threaded connection or other ways.

[0037] As shown in the figure, Figure 4 When the lamp cover body 1 and the lamp holder 2 need to be assembled, the operator first places the lamp cover body 1 below the lamp holder 2, and the connecting column 4 and the sleeve 6 are positioned correspondingly. Under normal circumstances, due to gravity, the connecting pin 12 and the magnet 14 on the connecting pin 12 are in the lowest state, and the magnet 14 protrudes out of the sleeve 6. At this time, the operator can use the ferromagnetic tapered buckle 5 to adsorb the lamp cover body 1 on the magnet 14 to realize temporary adsorption and fixation. This process utilizes the magnetic attraction of the magnet 14 to preliminarily position the lamp cover body 1 and the lamp holder 2.

[0038] When all the magnetic attraction is attracted to the conical buckle 5, the operator presses the lamp cover body 1 to the direction of the lamp holder 2. As shown in Figure 5 , the conical buckle 5 enters the sleeve 6. In this process, the lower end surface of the conical buckle 5 will be checked against the upper end surface of the positioning block 10. Since the positioning block 10 is wedge-shaped, when the conical buckle 5 presses the positioning block 10 upward, the positioning block 10 will drive the positioning pin 8 to slide in the sliding cavity 7, compressing the spring. When the conical buckle 5 completely enters the sleeve 6, the spring force will reset the positioning block 10 and tightly abut against the lower end surface of the conical buckle 5, thereby fixing the lamp cover body 1 in the lamp holder 2, realizing the installation and fixation of the lamp cover body 1 and the lamp holder 2.

[0039] Example two:

[0040] In this embodiment, in order to facilitate the disassembly and cleaning of the lamp cover, a sliding body 15 is specially provided. The connecting column 4 is provided with an annular groove, and the connecting column 4 is slidingly provided with a conical sliding body 15 at the position of the annular groove. The connection between the sliding body 15 and the connecting column 4 is realized through the annular groove, and the sliding body 15 can freely slide in the annular groove. The sliding body 15 is conical, and its taper surface is oppositely arranged with the taper surface of the conical buckle 5.

[0041] As shown in Figure 8 , one end of the conical buckle 5 is fixedly provided with a bolt 16, and a threaded hole 17 is formed in the connecting column 4, and the conical buckle 5 is fixedly connected with the connecting column 4 through the bolt 16 and the threaded hole 17. This connection method enables the processing personnel to conveniently assemble the conical buckle 5 and the sliding body 15 to the connecting column 4. The bolt 16 and the conical buckle 5 can be connected in an integral molding manner to ensure firm connection.

[0042] As shown in Figure 6 and Figure 7 , when the lamp cover needs to be disassembled for cleaning, the operator first pushes the lamp cover upward (the direction is drawn in the figure), so that the connecting column 4 moves upward. In this process, the connecting column 4 drives the sliding body 15 to move upward together, and the position of the sliding body 15 exceeds the position of the positioning block 10 (as shown in Figure 7 ). Since the taper surface of the sliding body 15 is opposite to the direction of the conical buckle 5, when the sliding body 15 exceeds the positioning block 10, the operator pulls the lamp cover downward again. At this time, the taper surface of the sliding body 15 will contact the positioning block 10, and since the taper surface of the sliding body 15 gradually expands downward, when the sliding body 15 moves downward, its taper surface will push the positioning block 10 to move to the side wall direction of the sleeve 6, so that the positioning block 10 drives the positioning pin 8 to slide in the sliding cavity 7, compressing the spring.

[0043] With the sliding body 15 continues to move down, its taper will gradually push the positioning block 10, make the positioning block 10 no longer fixed to the conical buckle 5. At this time, the operator can be through the taper of sliding body 15 the lampshade body 1 is taken off from the lamp holder 2. Such design makes the disassembly of the lampshade very convenient, the operator need not use complicated tool, only need to through simple push, pull operation can complete the disassembly of the lampshade, greatly improves the cleaning and maintenance efficiency of the lampshade.

[0044] Embodiment three:

[0045] Mosquitoes are usually attracted by light, if there is a large gap between the lampshade body 1 and the lamp holder 2, mosquitoes may enter the inside of the lampshade, affect the appearance and lighting effect of the lamp.

[0046] In the LED ceiling lampshade, the lampshade body 1 is provided with a necking ring 19. The necking ring 19 is usually made of materials with certain elasticity and flexibility, such as rubber, silicone and the like. The necking ring 19 can be connected with the lampshade body 1 by bonding, inlaying or clamping and the like. For example, a groove can be provided on the edge of the lampshade body 1, and the necking ring 19 is inlaid in the groove, so as to ensure that the necking ring 19 is firmly fixed on the lampshade body 1.

[0047] The existence of the necking ring 19 forms an effective barrier to prevent mosquitoes from entering. At the same time, the necking ring 19 can also play a certain dustproof role, reduce the dust into the inside of the lampshade, keep the cleanliness and brightness of the lamp.

[0048] Working principle: in the process of using the utility model, the installation process:

[0049] Firstly, through the several mounting holes 18 on the lamp holder 2, the lamp holder 2 is firmly installed on the ceiling by using screws and other fasteners. The lamp holder 2 is fixedly provided with an LED lamp panel to provide illumination for the whole space.

[0050] The operator places the lampshade body 1 below the lamp holder 2, so that the connecting column 4 fixed on the lampshade body 1 corresponds to the sleeve 6 fixed on the lamp holder 2. In the normal state, due to gravity, the connecting pin 12 in the positioning ring 11 in the sleeve 6 and the magnet 14 on the connecting pin 12 are in the lowest state, and the magnet 14 extends out of the sleeve 6.

[0051] At this time, the operator uses the ferromagnetic conical buckle 5 to adsorb the lampshade body 1 on the magnet 14, realizing temporary adsorption and fixation. This process utilizes the magnetic attraction of the magnet 14 to preliminarily position the lampshade body 1 and the lamp holder 2.

[0052] Once all the magnetic clips have attracted the conical buckles 5, the operator presses the lampshade body 1 toward the lamp holder 2. The conical buckles 5 enter the sleeve 6, and during this process, the lower end face of the conical buckles 5 abuts against the upper end face of the positioning block 10.

[0053] Since the positioning block 10 is wedge-shaped, when the conical buckle 5 presses the positioning block 10 upward, the positioning block 10 will drive the positioning pin 8 to slide in the sliding cavity 7, compressing the spring. When the conical buckle 5 is fully inserted into the sleeve 6, the spring force will cause the positioning block 10 to reset and press tightly against the lower end face of the conical buckle 5, thereby fixing the lampshade body 1 in the lamp holder 2, realizing the installation and fixation of the lampshade body 1 and the lamp holder 2.

[0054] Disassembly process

[0055] When the lamp cover needs to be removed for cleaning, the operator first pushes the lamp cover upward, causing the connecting column 4 to move upward. During this process, the connecting column 4 moves the sliding body 15 upward together, and the position of the sliding body 15 exceeds the position of the positioning block 10.

[0056] Since the direction of the conical surface of the sliding body 15 is opposite to that of the conical buckle 5, after the sliding body 15 passes the positioning block 10, the operator pulls the lamp cover down. At this time, the conical surface of the sliding body 15 will contact the positioning block 10.

[0057] Since the cone surface of the sliding body 15 gradually expands downward, when the sliding body 15 moves downward, its cone surface will push the positioning block 10 to move towards the side wall of the sleeve 6, thereby causing the positioning block 10 to drive the positioning pin 8 to slide in the sliding cavity 7 and compress the spring.

[0058] As the slider 15 continues to move downward, its conical surface will gradually push the positioning block 10 away, so that the positioning block 10 no longer fixes the conical buckle 5.

[0059] At this point, the operator can remove the lampshade body 1 from the lamp holder 2 using the conical surface of the sliding body 15, thus completing the disassembly of the lampshade. This design makes the disassembly of the lampshade very convenient, greatly improving the efficiency of cleaning and maintenance.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
