DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 9 As shown, the utility model provides an LED lamp that is easy to replace the LED lamp, including a fixing plate 1, a lamp box 4 is fixedly installed at the bottom of the fixing plate 1, and a cavity 5 is opened inside the lamp box 4;

[0029] The bottom of the left and right sides of the lamp box 4 are provided with locking grooves 12, and a locking rod 13 is movably placed inside the locking groove 12. One end of the locking rod 13 away from the cavity 5 passes through the lamp box 4, and the other end of the locking rod 13 is fixedly installed with a locking block 30 located inside the locking groove 12. The outer surface of the locking rod 13 is movably sleeved with a second spring 14, and the locking block 30 is elastically connected to the inner side surface of the locking groove 12 through the second spring 14;

[0030] A power-on end 11 is movably connected above the locking block 30 , a lamp post 15 is fixedly installed below the power-on end 11 , a heat sink 16 is fixedly installed on the bottom outer surface of the lamp post 15 , a slider 18 is movably sleeved on the top of the heat sink 16 , and a lamp 17 is fixedly installed at the bottom of the lamp post 15 .

[0031] Working principle: When the user needs to replace the LED lamp, the user needs to push the LED lamp upward. At this time, the top of the slider 18 and the outer inclined surface of the locking block 30 are squeezed against each other. At this time, the locking block 30 will continue to elastically shrink into the locking groove 12. When the slider 18 passes through the locking block 30, the squeezing force disappears and the elastic effect will reset the locking block 30. At this time, when the user pulls the lamp 17 downward, the power-on end 11 and the slider 18 move downward together, and the bottom of the slider 18 and the locking block 30 are squeezed against each other, causing the locking block 30 to shrink into the locking groove 12. At this time, it is necessary to pull down quickly to remove the LED lamp.

[0032] Beneficial effect: When replacing the LED lamp, the user needs to push the lamp 17 upwards so that the slider 18 and the power-on end 11 are both located inside the cavity 5, and then quickly pull it downwards. This structure can ensure a tight connection between the connectors and is not easy to loosen, thereby providing high reliability. Whether in an environment with vibration or strong impact, a stable connection state can be maintained. It can also be disassembled quickly, avoiding the need to use a variety of auxiliary tools during replacement and installation, which is complicated, cumbersome, time-consuming and labor-intensive.

[0033] Among them, self-locking boxes 19 are fixedly installed on both sides of the front and rear bottom of the lamp box 4, a self-locking hole 20 is opened on the outside of the self-locking box 19, a card slot 26 is opened at the bottom of the self-locking box 19, and a card block 27 is movably sleeved inside the card slot 26. A connecting cap 21 is fixedly installed on the outside of the self-locking hole 20, and a self-locking ball 22 is movably placed inside the self-locking hole 20. The self-locking ball 22 is elastically connected to the connecting cap 21 through a third spring 25, and self-locking grooves 28 are opened on both sides of the left and right sides of the card block 27.

[0034] Working principle: When installing, the user only needs to push the card block 27 into the card slot 26. At this time, the self-locking ball 22 will shrink into the self-locking hole 20 under the extrusion. When the user continues to push upward, the self-locking ball 22 is completely embedded in the self-locking slot 28, and the extrusion force disappears, and the fixing effect can be achieved. When the user needs to remove it, he only needs to pull it downward. As above, the self-locking ball 22 is squeezed into the self-locking hole 20. When it is completely pulled out, it can be removed.

[0035] Beneficial effects: When the lampshade needs to be cleaned or replaced, the user only needs to pull it downward to disengage the self-locking groove 28 from the self-locking ball 22, and then the lampshade can be easily removed from the lamp, making maintenance work simple and quick. This greatly reduces the time and effort required to replace or clean the lampshade. This design can save maintenance time and improve maintenance efficiency. Since the easily disassembled lampshade is easy to clean and maintain, it helps to maintain the cleanliness and performance of the lamp, thereby extending the service life of the lamp. At the same time, when the lampshade is damaged or needs to be replaced, the user can easily replace it by himself without having to replace the entire lamp.

[0036] Among them, telescopic holes 6 are opened on both sides of the top of the cavity 5, and a telescopic rod 7 is movably sleeved inside the telescopic hole 6. The telescopic rod 7 extends downward to the inside of the cavity 5 and a circuit board 8 is fixedly installed. The outer surface of the telescopic rod 7 is movably sleeved with a first spring 9. The top of the circuit board 8 is elastically connected to the top of the inner cavity of the cavity 5 through the first spring 9, and the middle of the circuit board 8 is fixedly connected to an electric wire 10.

[0037] Beneficial effect: When the user installs the LED lamp, when the power-on end 11 is installed inside the lamp box 4, the power-on end 11 will fit with the circuit board 8. When the LED lamp needs to be removed, the user pushes upward, and the telescopic rod 7 will elastically contract inward toward the telescopic hole 6 through the first spring 9. The LED lamp is always fitted with the circuit board after installation, and the circuit can be kept unobstructed when the LED lamp can be quickly replaced, avoiding performance degradation due to power failure, and circuit failure due to quick replacement, saving the user's time and energy.

[0038] The outer surfaces of the power-carrying end 11 and the slider 18 are smooth cones, and the tops and bottoms of the power-carrying end 11 and the slider 18 are chamfered.

[0039] Beneficial effect: When the user pushes the LED lamp upward, the slider 18 will be placed at the bottom of the lamp post 15 due to its own gravity. Since the power-on end 11 and the slider 18 are smooth cones and have a chamfered design, it is easier for the user to push and pull.

[0040] The heat dissipation block 16 has gaps on its circumference, and the gaps are evenly distributed.

[0041] Beneficial effects: Through the regular arrangement of multiple aluminum sheets, the contact area with the air is increased, and heat is dissipated through thermal radiation and air convection. The process is relatively simple, the production and processing are convenient, and the service life of the LED lamp is greatly improved.

[0042] A limiting rod 23 is fixedly installed in the middle of the self-locking ball 22 , a limiting groove 24 is provided at the end of the self-locking hole 20 , and the limiting rod 23 is located inside the limiting groove 24 .

[0043] Beneficial effects: It prevents the self-locking ball 22 from exceeding the predetermined range of motion during movement, avoids collision with other parts and causes damage, ensures that the self-locking ball 22 moves in a predetermined direction and position, and improves stability.

[0044] The top of the power supply end 11 and the bottom of the circuit board 8 are both provided with circuit contacts.

[0045] Beneficial effect: When the user is using it, due to the quick replacement of the LED lamp, the circuit may not be completely closed. This design can make the circuit completely unblocked when the user is using the LED lamp, which is convenient, fast and simple in structure.

[0046] The working principle and use process of this utility model:

[0047] When the user needs to replace the LED lamp, the user needs to push the LED lamp upwards. At this time, the top of the slider 18 and the outer inclined surface of the locking block 30 are squeezed against each other. At this time, the locking block 30 will continue to elastically shrink into the locking groove 12. When the slider 18 passes through the locking block 30, the squeezing force disappears and the elastic effect will reset the locking block 30. At this time, when the user pulls the lamp 17 downward, the power-on end 11 and the slider 18 move downward together, and the bottom of the slider 18 and the locking block 30 are squeezed against each other, causing the locking block 30 to shrink into the locking groove 12. At this time, it is necessary to pull downward quickly to remove the LED lamp.

[0048] When installing, the user only needs to push the block 27 into the slot 26. At this time, the self-locking ball 22 will shrink into the self-locking hole 20 under the extrusion. When the user continues to push upward, the self-locking ball 22 is completely embedded in the self-locking slot 28, and the extrusion force disappears, and the fixing effect can be achieved. When the user needs to remove, he only needs to pull downward. As above, the self-locking ball 22 is squeezed into the self-locking hole 20. When it is completely pulled out, it can be removed.
