[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Please refer to Figure 1-5 As shown, a protective cover with an unlocking structure includes a protective cover body 1, on which an unlocking mechanism 3 for fixing a waterproof cover 2 is provided, and the waterproof cover 2 is threadedly rotated and fixed to the protective cover body 1; wherein, the unlocking mechanism 3 includes a locking portion 301 sleeved on the protective cover body 1, and an unlocking portion 302 cooperating with the locking portion 301, the protective cover body 1 is provided with an elastic stopper 4 cooperating with the unlocking mechanism 3 to unlock, and the inner wall of the opening of the waterproof cover 2 is provided with a plurality of evenly arranged abutment grooves 5, and the elastic stopper 4 is movably abutted against the abutment grooves 5.

[0024] Specifically, an unlocking mechanism for fixing the waterproof cover is provided on the protective cover. The unlocking mechanism is first fixed to the protective cover, and then the waterproof cover is fixedly connected to the protective cover by rotating the thread. When the waterproof cover is screwed onto the protective cover, the abutment groove on the inner wall of the waterproof cover and the elastic stopper on the protective cover can fit tightly, that is, the elastic stopper is placed in the abutment groove so that the waterproof cover cannot be rotated in the opposite direction to separate from the protective cover. The elastic stopper plays a fixed locking role. When the waterproof cover needs to be separated from the protective cover, the elastic stopper can be separated from the abutment groove through the unlocking mechanism, and then the waterproof cover can be screwed off the protective cover. This design further plays a fixed locking role on the waterproof cover, preventing the waterproof cover from being easily screwed out, and the unlocking mechanism is easy to install and can quickly unlock the waterproof cover.

[0025] In this embodiment, an annular protrusion 6 is provided at the end of the protective cover body 1, and an annular groove 7 is formed between the annular protrusion 6 and the protective cover body 1; wherein, a plurality of buckles 8 are provided on the inner wall of the locking portion 301, and an unlocking groove 9 is also provided on the locking portion 301, and a first card slot 10 and a second card slot 11 are respectively provided on both sides of the unlocking groove 9; a toggle portion 12 is provided on the unlocking portion 302, and a pressing portion 13 is provided opposite to the toggle portion 12.

[0026] Specifically, the unlocking mechanism is first pressed onto the protective cover as a whole. The unlocking mechanism is fixed to the outer periphery of the protective cover through the mutual cooperation between the annular groove and the buckle. The unlocking part is placed in the unlocking groove as a whole. The first and second clamping grooves are provided on both sides of the unlocking groove. When one end of the unlocking part is pushed into the first clamping groove by the toggle part, the pressing part presses the elastic baffle inward, thereby pressing the elastic baffle out of the abutment groove, so that the waterproof cover loses the limiting and fixing effect of the elastic block, and the waterproof cover can be rotated out and separated from the protective cover. The unlocking mechanism is simple to install as a whole, and unlocking the waterproof cover is simple, quick, and easy to operate. The unlocking mechanism is preferably made of plastic to reduce the manufacturing cost and effectively lock and fix the waterproof cover.

[0027] In this embodiment, the outer side walls of the first card slot 10 and the second card slot 11 are respectively provided with a first groove 14 and a second groove 15 , and both ends of the unlocking portion 302 are provided with protrusions 16 respectively cooperating with the first groove 14 and the second groove 15 .

[0028] Specifically, the first groove and the second groove cooperate with the protrusions at both ends of the unlocking portion to prevent the unlocking portion from being easily moved, thereby playing a fixing role.

[0029] In this embodiment, a limiting portion 17 is further provided at the lower end of the second slot 11, and a limiting groove 18 is provided on the unlocking portion 302 to cooperate with the limiting portion 17. The limiting portion and the limiting groove cooperate to limit and fix the unlocking portion.

[0030] In this embodiment, a base 19 is detachably provided at the bottom of the protective cover body 1. Specifically, the base fixes the protective cover to the photovoltaic inverter through nuts.

[0031] In this embodiment, mounting portions 20 are provided on both sides of the protective cover body 1 , and fixing buckles 21 are provided on the mounting portions 20 . Raised fixing portions 22 are provided on both sides of the base 19 , and fixing holes 23 are provided on the fixing portions 22 to cooperate with the fixing buckles 21 .

[0032] Specifically, the fixing buckle is snap-fitted and fixed to the fixing hole, and can be further fixed by a nut.

[0033] In this embodiment, the mounting portion 20 is an elastic mounting portion.

[0034] Specifically, the mounting portion is designed to be an elastic mounting portion, and the elasticity of the mounting portion can be utilized to press the mounting portions on both sides inward to disengage the fixing buckle from the fixing hole.

[0035] In this embodiment, baffles 24 are further provided on both sides of the fixing portion 22 .

[0036] Specifically, the baffle on the fixing portion plays a role in limiting and fixing the mounting portion, and the mounting portion is placed between the two baffles.

[0037] Specifically, the unlocking mechanism is forcibly pressed into the protective cover via a buckle, and the waterproof cover is then locked to the protective cover body by rotating the thread. This places the elastic block in the abutment groove, fixing the waterproof cover to the protective cover body. The waterproof cover is locked by the unlocking mechanism and cannot be rotated in the opposite direction to unlock. To unlock, the toggle part is manually or with a tool to move it toward the first slot, allowing the pressing part to disengage the elastic block from the abutment groove. This unlocks the waterproof cover and allows it to be rotated out. The entire unlocking process can be completed by simply moving the toggle part left and right.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
