Technical Field
[0001] This utility model relates to the field of lamp junction box technology, and in particular to a lamp junction box with a protective structure. Background Technology
[0002] As a critical node in building electrical wiring, the surrounding area of the light junction box often needs cleaning or repainting during wall decoration and maintenance. However, after installation, the live terminals inside the existing light junction box are directly exposed to the work environment. Operators are highly susceptible to short circuits due to accidental tool contact or paint seepage during wall treatment, posing a significant safety hazard. Traditional temporary protective measures often involve attaching or removing the light junction box with tape. The former has poor sealing and easily leaves adhesive residue, while the latter requires power disconnection, affecting construction efficiency. Therefore, this solution proposes a light junction box with a protective structure to address the above problems. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This utility model provides, for example Figure 1 - Figure 4 The lamp box with a protective structure shown includes: Chassis 1; Isolation cover 2 is fitted on top of chassis 1 and is used to protect chassis 1; Positioning component 5 includes a snap-fit component located at the connection between chassis 1 and isolation cover 2. The snap-fit component is used to fix the position of isolation cover 2. An unlocking component is provided on the top of isolation cover 2.
[0018] It should be noted that the isolation cover 2 is made of plastic. When using it, first put the isolation cover 2 on the top of the chassis 1, and then fix the isolation cover 2 to the chassis 1 with the snap-fit. This allows the wall to be cleaned or painted without powering off, avoiding the risk of electric shock due to improper operation during the installation of the light box.
[0019] Specifically, a power cord 3 is installed on the top of the chassis 1, and a lamp holder 4 is installed on the top of the power cord 3. A first through hole 201 is opened in the middle of the isolation cover 2, and the power cord 3 is inserted and connected inside the first through hole 201.
[0020] It should be noted that the power cord 3 is used to connect the chassis 1 and the lamp head 4, and power is input to the chassis 1 through the power cord 3 during use; the isolation cover 2 is slidably fitted on the power cord 3, so that the isolation cover 2 can slide on the power cord 3.
[0021] Specifically, the latching component includes a second elastic plate 502 disposed at the bottom of the isolation cover 2, a first latching block 503 fixedly connected to one side of the second elastic plate 502, a first elastic plate 501 fixedly connected to the top of the chassis 1, a second latching block 504 fixedly connected to one side of the first elastic plate 501, and an unlocking component including second through holes 505 symmetrically opened on both sides of the isolation cover 2, a pressing block 506 fixedly connected to the inner wall of one side of the second through hole 505, the second elastic plate 502 fixedly connected to the bottom end of the pressing block 506, a limiting frame 6 fixedly connected to the top of the chassis 1, and the second elastic plate 502 inserted into the interior of the limiting frame 6.
[0022] It should be noted that the isolation cover 2, the second elastic plate 502, and the first locking block 503 are all integrally injection molded and made of plastic. The chassis 1, the first elastic plate 501, the second locking block 504, and the limiting frame 6 are also integrally injection molded and made of plastic. The plastic material design allows the first elastic plate 501 and the second elastic plate 502 to deform under pressure. When the pressure is released, the first elastic plate 501 and the second elastic plate 502 will recover their deformation and reset. The limiting frame 6 is used to block the front and back of the second elastic plate 502 during use, preventing the second elastic plate 502 from moving freely. By restricting the movement of the second elastic plate 502, the isolation cover 2 is restricted, preventing the isolation cover 2 from rotating on the top of the chassis 1 when its position is fixed, which could cause the first locking block 503 and the second locking block 504 to separate.
[0023] Furthermore, when it is necessary to fix the isolation cover 2 to the top of the chassis 1, the isolation cover 2 is moved to one side of the chassis 1, so that the first locking block 503 and the second locking block 504 are in contact. At this time, the isolation cover 2 is pressed to one side of the chassis 1, so that the first locking block 503 and the second locking block 504 cause the second elastic plate 502 and the first elastic plate 501 to deform. When the first locking block 503 moves to the bottom of the second locking block 504, the second elastic plate 502 and the first elastic plate 501 deform. 1. The deformation is restored, and the isolation cover 2 cannot be moved freely from the top of the chassis 1 by the obstruction of the first locking block 503 and the second locking block 504. When it is necessary to separate the isolation cover 2 from the top of the chassis 1, the pressing block 506 is pressed down, and the second elastic plate 502 is moved away from the first elastic plate 501 by the pressing block 506, so that the first locking block 503 and the second locking block 504 are separated, and then the isolation cover 2 can be moved away from the chassis 1.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
