[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-4 As shown, a hook assembly includes a hook reinforcement plate 2 and a hook body 3;

[0029] Both the fastener reinforcement plate 2 and the fastener body 3 are provided in two sets. The fastener reinforcement plate 2 is used to fix on the back side of the chassis body 1. In one embodiment, the bottom of the fastener reinforcement plate 2 is used to fix on the back side of the chassis body 1, and the side of the fastener body 3 is fixedly installed on the side of the fastener reinforcement plate 2. The bottom of the fastener body 3 is used to fix on the back side of the chassis body 1. The fastener reinforcement plate 2 strengthens the stability of the fastener body 3 installation.

[0030] The main body 3 of the fastener consists of a main fixing plate 31, an arched face frame 33, and several face frame connectors 32 that connect the main fixing plate 31 and the arched face frame 33. The two ends of the arched face frame 33 are respectively provided with a first hook 36 and a second hook 37 for the main body of the fastener, which are used to hang on the matching wall bracket to achieve quick installation. The arched face frame 33 is provided with an arched surface, and the arched surface structure (bridge structure) improves the stability of the main body of the fastener.

[0031] The aforementioned fastener reinforcing plate 2 and fastener body 3 are not an integral structure. They can be processed using different techniques before installation and fixation, such as aluminum extrusion + aluminum extrusion, die casting + die casting, aluminum extrusion + die casting, or some other combination of processes.

[0032] In some specific implementations, the fastener reinforcing plate 2 is an L-shaped reinforcing plate, and the two side strips of the L-shaped reinforcing plate 2 are respectively provided with a first through hole 21 and a second through hole 22.

[0033] The first through hole 21 of the reinforcing plate is provided with a first connecting piece 4 of the reinforcing plate, and the main body 1 of the chassis is provided with a number of reinforcing plate fixing holes 12. The end of the first connecting piece 4 of the reinforcing plate is threaded into the fixing hole 12 of the reinforcing plate.

[0034] The main body 3 of the fastener is installed on both sides of the back of the main body 1 of the chassis. The main body 3 of the fastener has several first threaded holes 34. The second through hole 22 of the reinforcing plate has a second connecting piece 6. The end of the second connecting piece 6 is threaded into the first threaded hole 34 of the fastener to reinforce the main body 3.

[0035] In some specific implementation schemes, the main fixing plate 31 is provided with a number of fixing plate through holes 311, the fixing plate through holes 311 are provided with a hook fastener main body connector 5, the main body of the chassis 1 is provided with a number of hook fastener fixing holes 11, and the end of the hook fastener main body connector 5 is threaded to the hook fastener fixing hole 11.

[0036] In one embodiment, there are at least two through holes 311 in the fixing plate, and at least one through hole 311 is provided at each end of the main fixing plate 31; in another embodiment, at least one through hole 311 in the middle of the main fixing plate 31 is provided, wherein the middle of the main fixing plate 31 refers to the position on the main fixing plate 31 between each pair of faceplate connectors 32.

[0037] The first connecting piece 4 of the reinforcing plate, the main connecting piece 5 of the hook fastener, and the second connecting piece 6 of the reinforcing plate can all be fixed with screws.

[0038] In some specific implementations, the arched frame 33 is provided with a number of arched through holes 331. The position of the arched through holes 331 corresponds to the position of the fixing plate through hole 311 located in the middle of the main body fixing plate 31. When fixing the main body connector 5 of the fastener to the chassis body 1, the main body connector 5 of the fastener can be placed in the fixing plate through hole 311 located in the middle of the main body fixing plate 31. Then, the fastening tool (such as a screwdriver) passes through the arched through hole 331 and contacts the main body connector 5 of the fastener. The main body fixing plate 31 and the chassis body 1 are fixed through the main body connector 5 of the fastener. For example, when the main body connector 5 of the fastener is a screw or bolt, the screwdriver passes through the arched through hole 331 and tightens the main body connector 5 of the fastener.

[0039] In a further implementation scheme, the faceplate connector 32 can be adopted as follows: Figure 1 The connecting column shown can also be used as follows: Figure 5 The tripod shown has an arched frame 33 with a hook and handle slot 38 inside the arched surface, which matches the fingers for easy handling.

[0040] In some specific implementations, the main body 3 of the hook fastener is provided with a second threaded hole 35, and a handling handle 7 is threadedly connected to the second threaded hole 35 of the hook fastener to facilitate the handling and disassembly of the handle.

[0041] The aforementioned hook assembly has at least the following beneficial effects:

[0042] 1. The arched surface and bridge-shaped structure of the main body of the fastener improve the stability of the main body of the fastener.

[0043] 2. The reinforcing plate of the fastener increases the contact area with the main body of the chassis, preventing the main body of the fastener from tilting during transportation and avoiding cracking of the fixed position of the main body of the chassis.

[0044] 3. The arched mounting plate of the hook fastener is fixed with through holes to enhance the wall-mounting strength. Additionally, this utility model also provides a power electronic device, including a chassis body 1 and the aforementioned hook fastener assembly, which is fixed to the back side of the chassis body 1.

[0045] In one embodiment, the bottom of the fastener reinforcing plate 2 and the bottom of the fastener body 3 are fixed to the back side of the chassis body 1, and the side of the fastener body 3 is fixedly installed on the side of the fastener reinforcing plate 2. Through the cooperation of the fastener reinforcing plate 2 and the fastener body 3, the fastener body 3 is prevented from tilting during transportation, avoiding cracking of the chassis body fixing position, and enhancing the wall-mounting strength, wall-mounting stability and reliability of the chassis body.

[0046] It is understood that the aforementioned power electronic equipment can specifically be inverters or other related power electronic equipment. Of course, in addition to power electronic equipment enclosures, enclosures in other application scenarios where there is an explosion risk can also adopt the above-mentioned hook-and-loop assembly structure, without further specific limitations here.
