[0030] In order to solve the problem of electric shock in the process of reinstalling and using the lamp after disassembly in the prior art, the utility model provides an anti-disassembly structure and a lamp, wherein the anti-disassembly structure is a part of the lamp. In this embodiment, the lamp is a spotlight, a downlight or the like.

[0031] like Figures 1 to 4 As shown, the anti-disassembly structure includes a cylinder 10 and a protective cover 20, the cylinder 10 has an installation cavity 110 with an opening at one end, the protective cover 20 includes a front cover body 210 and a rear cover body 230 arranged at intervals along the axial direction of the cylinder 10, and a connecting member 220 arranged between the front cover body 210 and the rear cover body 230, the front cover body 210 and the rear cover body 230 are annular structures, and notches 221 are formed at intervals at both ends of the circumferential connecting member 220 of the front cover body 210 and the rear cover body 230, the rear cover body 230 is arranged inside the installation cavity 110 and connected to the cylinder 10, and the front cover body 210 is arranged on the side of the rear cover body 230 facing the opening.

[0032] Among them, the barrel 10 is a cylindrical structure, and the corresponding installation cavity 110 is a cylindrical structure. During the installation of the protective cover 20, the anti-disassembly structure is installed into the installation cavity 110 through the opening, so as to realize the protection of the protective cover 20 through the barrel 10.

[0033] Specifically, the protective cover 20 used in this embodiment adopts a front cover body 210 and a rear cover body 230 that are axially spaced apart, so that during the process of forcibly dismantling the protective cover 20, the connecting piece 220 between the front cover body 210 and the rear cover body 230 will be broken, thereby achieving that only the front cover body 210 is disengaged from the mounting cavity 110 of the same body, and the rear cover body 230 remains installed with the cylinder body 10, and the circuit is not damaged, thereby avoiding the risk of electric shock. When the protective cover 20 in this embodiment is forcibly dismantled, the front cover body 210 and the rear cover body 230 are separated, so the protective cover 20 in this embodiment avoids the imagination of being forcibly dismantled by non-professionals and then reinstalled on the cylinder body 10, thereby overcoming the possible risk of electric shock.

[0034] Furthermore, the front cover body 210 , the rear cover body 230 and the barrel body 10 are coaxial to facilitate the installation of the protective cover 20 into the installation cavity 110 , wherein the end of the front cover body 210 of the protective cover 20 away from the rear cover body 230 is flush with the opening end of the barrel body 10 .

[0035] like Figure 3 and Figure 4 As shown, along the axial direction of the barrel 10, the extension length of the front cover 210 is greater than the extension length of the rear cover 230. The extension length of the front cover 210 is greater than the extension length of the rear cover 230 to facilitate the installation of the protective cover 20.

[0036] The connecting piece 220 of the present embodiment is formed with a notch 221 in the circumferential direction of the cylinder body 10, so that during the process of forcibly removing the protective cover 20, the connecting piece 220 is easily broken due to the existence of the notch 221, thereby realizing the separation of the front cover body 210 and the rear cover body 230.

[0037] The front cover 210 and the rear cover 230 in this embodiment are annular structures, so as to facilitate the emission of light to the outside of the barrel 10 through the center of the annular structure.

[0038] In this embodiment, the protective cover 20 is connected to the cylinder body 10 using a rear cover body 230 located inside the installation cavity 110, so that during the process of removing the protective cover 20, since the connection position between the protective cover 20 and the cylinder body 10 is located on the side away from the opening of the cylinder body 10, it is not easy to fall off without being subjected to force, which is beneficial to improving the stability of the connection between the protective cover 20 and the cylinder body 10.

[0039] Among them, since the connection position is set on the rear cover body 230, during the process of forcibly dismantling the protective cover 20, the connecting piece 220 breaks after the front cover body 210 is subjected to force, and the front cover body 210 falls out of the installation cavity 110. At this time, the rear cover body 230 and the cylinder body 10 can remain connected.

[0040] It should be noted that the protective cover 20 of the present embodiment is made of plastic, which is an insulating material, and the protective cover 20 can be integrally injection molded.

[0041] like Figure 3 and Figure 4 As shown, the rear cover 230 has a connecting portion 231 , which is connected to the cylinder 10 . Along the axial direction of the cylinder 10 , the connecting portion 231 is arranged at one end of the rear cover 230 away from the front cover 210 .

[0042] Among them, the connecting part 231 is set at a position of one end of the rear cover body 230 away from the front cover body 210, so that the connecting part 231 is set away from the opening of the cylinder body 10, that is, the mounting part is set at a deeper position of the cylinder body 10, thereby achieving that the protective cover 20 is not easy to fall off when the protective cover 20 is not subjected to force.

[0043] In this embodiment, the inner wall surface of the cylinder 10 has a mating portion that is snap-fitted with the connecting portion 231, so that the rear cover body 230 of the protective cover 20 can be connected to the cylinder 10 by snap-fitting, and a detachable structure cannot be realized. At the same time, the snap-fitting structure is convenient for assembly, which is beneficial to improving installation efficiency.

[0044] Among them, one of the connecting part 231 and the matching part is a buckle, and the other of the connecting part 231 and the matching part is a slot. The structural setting of the buckle and the slot facilitates processing; and the protective cover 20 only needs to be moved to the inside of the installation cavity 110 to complete the buckle connection to the slot, which is convenient for operation and is conducive to improving processing efficiency.

[0045] In a preferred embodiment, the connecting portion 231 is a buckle, and the matching portion is a slot, and the buckle and the slot are engaged with each other to fix the protective cover 20 inside the installation cavity 110.

[0046] In this embodiment, one connecting portion 231 is provided, or a plurality of connecting portions 231 may be provided, and the connecting portions 231 and the matching portions are provided one by one, so that the protective cover 20 and the cylinder 10 can be stably connected through the connecting portion 231. When a plurality of connecting portions 231 are provided, the plurality of connecting portions 231 are arranged at intervals along the circumference of the cylinder 10, so that the force between the protective cover 20 and the cylinder 10 is uniform. Preferably, the plurality of connecting portions 231 are arranged at equal intervals along the circumference of the cylinder 10; more preferably, four connecting portions 231 are provided, and the four connecting portions 231 are arranged at equal intervals along the circumference of the cylinder 10.

[0047] like Figure 4 As shown, the connecting member 220 is disposed between the end surfaces of the front cover 210 and the rear cover 230 that face each other.

[0048] Specifically, during the process of removing the protective cover 20, the connecting piece 220 is subjected to external force along the circumference of the cylinder body 10. The connecting piece 220 is arranged between the two end faces of the front cover body 210 and the rear cover body 230 of the annular structure and a notch 221 is formed. Therefore, the connection strength here is weak and prone to breakage, which is conducive to the connecting piece 220 breaking under the action of external force.

[0049] In a specific implementation manner not shown in the figure of the present embodiment, one connecting member 220 is provided, and the connecting member 220 may be a columnar connecting rib or an arc-shaped plate extending along the circumference of the cylinder 10; a single connecting member 220 is convenient for breaking when subjected to stress.

[0050] like Figures 1 to 4 In the specific embodiment shown, a plurality of connecting members 220 are provided. When a plurality of connecting members 220 are provided, the plurality of connecting members 220 are spaced apart along the circumference of the cylinder 10 .

[0051] Preferably, a plurality of connectors 220 are arranged at equal intervals along the circumference of the cylinder 10 ; in the present embodiment, three connectors 220 are provided, and the three connectors 220 are arranged at equal intervals along the circumference of the cylinder 10 .

[0052] In this embodiment, the connecting member 220 can be a columnar connecting rib or an arc-shaped plate extending along the circumference of the cylinder 10, wherein each connecting rib forms a notch 221 at both ends along the circumference of the cylinder 10. It can be understood that one of the connecting ribs is arranged inside the notch 221 of the other connecting rib; similarly, each arc-shaped plate forms a notch 221 at both ends along the circumference of the cylinder 10, and one of the arc-shaped plates is arranged inside the notch 221 of the other arc-shaped plate.

[0053] like Figure 3 and Figure 4 As shown, the outer wall surface of the front cover body 210 is provided with a groove 211 extending along the axial direction of the cylinder body 10, and the groove 211 is formed into a tearable structure.

[0054] Specifically, during the process of disassembling the protective cover 20 under force, when the front cover body 210 is under force, the external force will tear the tearable structure formed at the position of the groove 211, so that the front cover body 210 is damaged and the front cover body 210 cannot be restored and reinstalled, thereby avoiding the risk of electric shock when disassembling and using it again after reinstallation. The structural setting of the front cover body 210 of the present application that is torn and cannot be restored after being damaged by external force is conducive to improving installability.

[0055] Furthermore, the axial groove 211 along the barrel 10 is opened toward one end of the rear cover 230 , which is conducive to tearing at the position of the groove 211 when the front cover 210 is subjected to force.

[0056] In this embodiment, the connecting piece 220 is arranged along the circumference of the cylinder 10, and the groove 211 is arranged along the axial direction of the cylinder 10. When the protective cover 20 is disassembled by external force, the connecting piece 220 breaks to realize the axial separation of the front cover body 210 and the rear cover body 230 along the cylinder 10. The groove 211 on the front cover body 210 is torn, and there is a torn gap in the circumference of the front cover body 210. The protective cover 20 is damaged in both the circumferential and axial directions and cannot be restored, so that the protective cover 20 cannot be reinstalled.

[0057] like Figure 4 As shown, one end of the front cover 210 facing the rear cover 230 extends toward the axis of the barrel 10 to form a constriction structure 212, and the connector 220 is arranged on the end surface of the constriction structure 212 facing the rear cover 230. The setting of the constriction structure 212 is conducive to increasing the torsional force on the connector 220 when the front cover 210 is subjected to force, thereby achieving a fracture at the connector 220.

[0058] In this embodiment, the lamp includes the above-mentioned anti-dismantling structure, a light-emitting component, a lens and a power supply. The light-emitting component is arranged inside the installation cavity 110 of the barrel 10 of the anti-dismantling structure. The lens is arranged between the light-emitting component and the protective cover 20 of the anti-dismantling structure. The light of the light-emitting component is emitted toward the open end of the barrel 10 through the lens. The power supply is arranged on the barrel 10, and the power supply is electrically connected to the light-emitting component.

[0059] The power source is used for supplying power, and the light of the light emitting component passes through the lens and then through the protective cover 20 to be emitted outward.

[0060] The rear cover 230 is used to abut and fix the lens, so that after the front cover 210 falls off, the rear cover 230 remains connected to the barrel 10, so that the rear cover 230 remains in contact and fixes the lens, without damaging the internal circuit of the installation cavity 110, thereby avoiding the risk of leakage.

[0061] In this embodiment, the light-emitting assembly includes a lamp board, lamp beads arranged on the lamp board, and a pressing plate. The lamp beads are electrically connected to a power source, and are LED lamp beads. The pressing plate has a light hole for exposing the lamp beads. The pressing plate is detachably connected to the mounting plate. The lamp board is arranged between the pressing plate and the mounting plate. One end of the lens abuts against the pressing plate, and the other end of the lens abuts against the rear cover 230 of the protective cover 20. By clamping and fixing the lamp board with the pressing plate and the mounting plate, the stability of the installation of the lamp board is increased.

[0062] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0063] The protective cover 20 adopted in the present application adopts a front cover body 210 and a rear cover body 230 which are axially spaced apart so that during the process of forcibly removing the protective cover 20, the connecting piece 220 between the front cover body 210 and the rear cover body 230 will be broken, thereby achieving that only the front cover body 210 is removed from the mounting cavity 110 of the same body, and the rear cover body 230 remains installed with the cylinder body 10, the circuit is not damaged, and the risk of electric shock is avoided.

[0064] The protective cover 20 of the present application adopts a rear cover body 230 located inside the installation cavity 110 to be connected to the cylinder body 10, so that during the process of removing the protective cover 20, since the connection position between the protective cover 20 and the cylinder body 10 is located on the side away from the opening of the cylinder body 10, it is not easy to fall off without being subjected to force, which is beneficial to improving the stability of the connection between the protective cover 20 and the cylinder body 10.

[0065] The present application adopts a groove 211 extending along the axial direction of the cylinder 10 set on the front cover body 210, so that during the process of removing the protective cover 20, the groove 211 is subjected to force and torn, so that the front cover body 210 is damaged and cannot be reinstalled, avoiding the risk of electric shock caused by reinstallation in the prior art.
