[0026] By providing an LED drive power supply safety protection device in the embodiments of the present application, the problems that existing devices only dissipate heat through heat dissipation holes during use, resulting in poor heat dissipation effect, easy heat accumulation inside the device, leading to device damage and poor safety are effectively solved. When this device operates, it can keep the LED drive power supply in a suspended state through a specific structure and effectively achieve air circulation, further improving the protection effect and use safety.

[0027] Embodiment

[0028] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiments of the present application effectively solves the technical problems that existing devices only dissipate heat through heat dissipation holes during use, resulting in poor heat dissipation effect, easy heat accumulation inside the device, leading to device damage and poor safety. The general idea is as follows: An LED drive power supply safety protection device includes a protective housing 11. Heat dissipation grooves 12 are opened on both side walls of the protective housing 11. An air inlet 13 is opened at the lower end of the protective housing 11. A circulation fan 14 is installed inside the air inlet 13. When the device installs the LED drive power supply to operate, the circulation fan 14 can be started at this time. Under the action of the circulation fan 14, external air is drawn into the protective housing 11 and then blown out through the two heat dissipation grooves 12. Since the LED drive power supply is installed in a suspended state, the overall protection effect of the device is enhanced and the use safety is improved;

[0029] First protective strips 15 are symmetrically and fixedly installed on both side walls of the protective housing 11. First sliding grooves 16 are opened on the two groups of first protective strips 15. Second protective strips 17 are symmetrically and slidably installed in the two groups of first sliding grooves 16 respectively. Screws 18 are threadedly installed on both side walls of the protective housing 11;

[0030] Fixing mechanisms are symmetrically arranged on the inner side walls of the protective housing 11;

[0031] The fixing mechanism includes a placement bar 21, and the two placement bars 21 are symmetrically fixedly installed in the inner side wall of the protective shell 11. The two placement bars 21 are both provided with a second slide groove 22. The side walls of the two placement bars 21 that are opposite to each other are both symmetrically fixedly installed with a slide column 23. The two slide columns 23 are both slidably installed in the protective shell 11. The two groups of slide columns 23 are both symmetrically threaded with threaded rings 24. When in use, the two groups of second protection bars 17 can be respectively inserted into the two groups of first protection bars 15, and then the two groups of second protection bars 17 are fixed by the two groups of threaded rings 24. At this time, the two groups of second protection bars 17 cooperate with the two groups of first protection bars 15 to form protection for the protective shell 11, thereby enhancing the protection effect of the equipment.

[0032] A clamping strip 25 is slidably installed inside the two second slide grooves 22, and a first spring 26 is fixedly installed between the two clamping strips 25 and the two placement strips 21. Side rods 27 are fixedly installed on the side walls of the two clamping strips 25. The two first springs 26 are respectively sleeved on the two screw rods 18. Dovetail grooves 28 are opened on the two groups of side rods 27. Clamping blocks 31 are slidably installed inside the two groups of dovetail grooves 28. Second springs 32 are fixedly installed on the two groups of clamping blocks 31. One end of the two groups of second springs 32 away from the two groups of clamping blocks 31 is fixedly connected to the inner walls of the two groups of dovetail grooves 28. When in use, the LED driving power supply can be placed on the two placement strips 21 inside the protective shell 11 first, and then it can be placed on the protective shell 11. By rotating the two screw rods 18, the two clamping strips 25 will be squeezed and driven to move toward the middle under the rotation of the two screw rods 18. The two clamping strips 25 will be moved to clamp and fix the two sides of the LED driving power supply. When clamping and fixing the two sides of the clamping strips 25, the two groups of clamping blocks 31 will also be subjected to squeezing force. At this time, the two groups of clamping blocks 31 will slide outward inside the two groups of dovetail grooves 28. At this time, the two groups of clamping blocks 31 will also synchronously drive the two groups of second springs 32 to stretch accordingly. At this time, the two groups of second springs 32 will generate reverse elastic force, thereby enabling the two groups of clamping blocks 31 to complete the clamping and fixation of the other two sides of the LED driving power supply, so that the device is convenient for installing and disassembling the LED driving power supply when in use, and the fixing effect is better during installation.

[0033] In view of the problems existing in the prior art, the utility model provides a LED driving power supply safety protection device. When operating, the device can keep the LED driving power supply in a suspended state through a specific structure and effectively realize air circulation, thereby further improving the protection effect and safety of use.

[0034] Working principle:

[0035] In the first step, when using, the LED driving power supply can be placed on the two placement bars 21 inside the protective shell 11. At this time, the two screws 18 can be rotated on the protective shell 11. Under the rotation of the two screws 18, the two clamping bars 25 will be squeezed and driven to move toward the middle. Under the movement of the two clamping bars 25, the two sides of the LED driving power supply will be clamped and fixed. When the two sides of the clamping bars 25 are clamped and fixed, the two groups of clamping blocks 31 will also be subjected to extrusion force. At this time, the two groups of clamping blocks 31 will slide outward inside the two groups of dovetail grooves 28. At this time, the two groups of clamping blocks 31 will also synchronously drive the two groups of second springs 32 to stretch accordingly. At this time, the two groups of second springs 32 will generate reverse elastic force, thereby enabling the two groups of clamping blocks 31 to complete the clamping and fixing of the other two sides of the LED driving power supply, so that the device is convenient for installing and disassembling the LED driving power supply when in use, and the fixing effect is better during installation;

[0036] In the second step, when in use, the two sets of second protection strips 17 can be respectively inserted into the two sets of first protection strips 15, and then the two sets of second protection strips 17 are fixed by two sets of threaded rings 24. At this time, the two sets of second protection strips 17 and the two sets of first protection strips 15 will form protection for the protective housing 11, thereby enhancing the protection effect of the device;

[0037] The third step is to start the circulating fan 14 when the device is installed with the LED driver power supply. The circulating fan 14 will draw the external air into the protective housing 11 and then blow it out through the two heat dissipation slots 12. Since the LED driver power supply is installed in a suspended state, the overall protection effect of the device is enhanced and the safety of use is improved.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
