[0002] Lamps are a general term for lighting tools, which are divided into chandeliers, table lamps, wall lamps, floor lamps, etc. They refer to appliances that can transmit light, distribute and change the light distribution of light source groups. They include light source groups, all components required to fix and protect the light source groups, and the line accessories necessary for connecting to the power supply. In some implementation scenarios, such as agricultural production in greenhouses and other facilities, multiple light source groups need to be hoisted. In order to convert the power supply into a specific voltage and current to drive the LED to emit light, a driving power box is usually required.

[0003] Existing driver power boxes generally consist of a base and a top cover. During installation and wiring, the top cover is opened for operation. For example, Chinese patent publication number CN207422158U discloses a "power box for LED lamps." The box uses a die-cast aluminum housing with a grounding post for safe grounding and is CE certified. The die-cast housing can be designed in various styles, which is both beautiful and novel. It also uses a rubber ring for waterproofing, achieving IP65. The cavity designed in the housing facilitates the insertion of the power supply and glue filling. In addition, the separation of the power supply housing and the lamp body prevents heat concentration, reduces the amount of glue filling, and saves costs.

[0004] However, in actual use, since the back cover and the connecting plate are fixed with screws, installation and removal are inconvenient, which increases the difficulty of maintenance and wiring. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-4 A driving power supply box includes a base 1, a flip cover 2 and an upper cover 3 are provided on the base 1, a mounting plate is fixedly provided on the base 1, an extension portion 4 is provided on one side of the flip cover 2, and the extension portion 4 is rotatably connected to the mounting plate;

[0025] A connecting plate 5 is fixedly provided on the base 1, and an installation interval is formed between the connecting plate 5 and the base 1. The flip cover 2 and the upper cover 3 are plugged into the connecting plate 5 and cover the installation interval. A through slot 51 is provided on the connecting plate 5, and a clamping plate 52 is fixedly provided in the through slot 51. The clamping plate 52 is clamped to the flip cover 2, and the upper cover 3 is clamped to the base 1.

[0026] In the present invention, the flip cover 2 is rotatably connected to the base 1 and is engaged with the clamping plate 52 on the base 1, which makes it convenient to open the flip cover 2 for installation, wiring and maintenance. At the same time, the flip cover 2 can be fixed. The upper cover 3 is engaged with the base 1 to fix the upper cover 3, prevent the upper cover 3 from falling off, and improve safety.

[0027] Furthermore, in this embodiment, the card plate 52 is an elastic plate, and a limiting protrusion 521 is fixedly provided on the card plate 52, and a card slot 522 is provided on the flip cover 2 to cooperate with the limiting protrusion 521. When the flip cover 2 rotates and engages with the connecting plate 5, the limiting protrusion 521 is subjected to force to drive the card plate 52 to undergo elastic deformation. When the flip cover 2 is completely engaged with the connecting plate 5, the card plate 52 resets and drives the limiting protrusion 521 to engage with the card slot 522, thereby fixing the flip cover 2.

[0028] Furthermore, in this embodiment, a bayonet 53 is provided on the connecting plate 5, and an elastic member 54 with an arc-shaped structure is bent on the upper cover 3. The elastic member 54 is plugged into the bayonet 53 to fix the upper cover 3. The base 1 and the connecting plate 5 have a certain deformation ability. When the upper cover 3 is removed, the two sides of the base 1 are squeezed to cause elastic deformation. The bayonet 53 is separated from the elastic member 54 to remove the upper cover 3, thereby facilitating maintenance.

[0029] It should be noted that, in this embodiment, a limiting groove 55 is provided on one side of the bayonet, and an inner box 6 for installing a circuit board is provided in the base 1. The inner box 6 is provided with an elastic limiting portion 61 that cooperates with the limiting groove 55. The limiting portion 61 is engaged with the limiting groove 55 to fix the inner box 6 to prevent it from loosening. A switch is provided on the circuit board in the inner box 6, and a toggle groove corresponding to the switch is provided on the base 1, and a wiring hole is provided on the base 1.

[0030] In addition, in this embodiment, an anti-fool-proof protrusion 62 is fixedly provided on the inner box 6, and a positioning plate 31 is fixedly provided on the upper cover 3. The positioning plate 31 is provided with an anti-fool-proof groove 32 that cooperates with the anti-fool-proof protrusion 62. The anti-fool-proof groove 32 cooperates with the anti-fool-proof protrusion 62 to avoid deformation and damage of the upper cover 3 or the base 1 due to incorrect installation.

[0031] In detail, in this embodiment, the base 1 includes a bottom plate 11, both sides of the bottom plate 11 are bent to form a support plate 12, the connecting plate 5 is fixedly arranged on the support plate 12, and the other two sides of the bottom plate 11 are bent to form a baffle 13. There is a gap between the baffle 13 and the support plate 12, so that the support plate 12 can undergo a small deformation, which facilitates the removal of the upper cover 3.

[0032] To be more specific, in this embodiment, a slot 14 is provided on the support plate 12, a plug-in 15 that cooperates with the slot 14 is fixedly provided on the baffle 13, a limiting column 16 is provided in the slot 14, and a positioning groove that cooperates with the limiting column 16 is provided on the plug-in 15. By setting the plug-in 15 to be connected with the slot 14, the firmness of the base is increased, and the plug-in 15 is fixed by setting the limiting column 16 and the positioning groove to prevent the plug-in 15 from being misaligned with the slot 14.

[0033] Working method: When installing the flip cover 2, the flip cover 2 rotates and engages with the connecting plate 5, and the limiting protrusion 521 is subjected to force to drive the card plate 52 to undergo elastic deformation. When the flip cover 2 is completely engaged with the connecting plate 5, the card plate 52 resets and drives the limiting protrusion 521 to engage with the card slot 522 to fix the flip cover 2. When installing the upper cover 3, the anti-mistake groove 32 of the upper cover 3 corresponds to the anti-mistake protrusion 62, and the upper cover 3 is pressed down to cause the elastic member 54 to undergo elastic deformation. When the upper cover 3 is installed in place, the elastic member 54 corresponds to the bayonet 53, and the elastic member 54 resets and engages with the bayonet 53 to fix the upper cover 3.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
