Meanwhile, the elastic member 35 is disposed between the first connecting portion 332 and the second connecting portion 342, one end of the elastic member 35 is connected to the first connecting portion 332, and one end of the elastic member 35 is connected to the second connecting portion 342. Therefore, the elastic member 35 can form a tensile force between the first connecting portion 332 and the second connecting portion 342, and the second end of the first hinge lever 33 and the second end of the second hinge lever 34 can be moved closer together by the tensile force, and the first clamping portion 331 and the second clamping portion 341 can be moved closer together, so that the first clamping portion 331 and the second clamping portion 341 can be clamped and fixed to opposite sides of the clamp block 12, and the duct cover 2 can be fixed to the rear wall inside the cabinet 1.

In other embodiments, the elastic member 35 may be disposed at the first end of the first hinge rod 33 and the first end of the second hinge rod 34, so that the elastic member 35 may form a tensile force between the first end of the first hinge rod 33 and the first end of the second hinge rod 34, and the first clamping portion 331 and the second clamping portion 341 may be brought close to each other by the tensile force.

Referring to fig. 9 to 14, in some embodiments, the hinge shaft 32 is spaced from the front side wall of the accommodating chamber 30, that is, the hinge shaft 32 is spaced apart from the rear side of the duct cover 2. Accordingly, the second end of the first hinge lever 33, the second end of the second hinge lever 34, and the elastic member 35 are movably disposed in a spaced area between the hinge shaft 32 and the front sidewall of the receiving chamber 30.

Referring to fig. 5 and 7, in some embodiments, a first clamping groove 121 and a second clamping groove 122 are respectively recessed on opposite sides of the clamping block 12. When the air duct cover plate 2 is mounted on the rear wall of the interior of the box liner 1, the first clamping portion 331 and the second clamping portion 341 can respectively clamp and fix the positions of the first clamping groove 121 and the second clamping groove 122 on the opposite sides of the clamping block 12, that is, the first clamping portion 331 can be abutted against the groove wall of the first clamping groove 121, the second clamping portion 341 can be abutted against the groove wall of the second clamping groove 122, so that the first clamping portion 331 and the second clamping portion 341 can be clamped and fixed on the opposite sides of the clamping block 12, and then the air duct cover plate 2 is fixed on the rear wall of the interior of the box liner 1.

It should be noted that, in other embodiments, the first clamping portion 331 and the second clamping portion 341 may be clamped and fixed on two opposite sides of the clamping block 12 by providing the first clamping groove 121 on only one side wall of the clamping block 12 or providing the second clamping groove 122 on only the other side wall of the clamping block 12.

Referring to fig. 5 and 7, in some embodiments, the first clamping groove 121 is disposed in a long strip shape, and the extending direction of the first clamping groove 121 is consistent with the extending direction of the hinge shaft 32. Meanwhile, two ends of the first clamping groove 121 are respectively provided with a slope part 123, and the slope parts 123 extend from the bottom surface of the first clamping groove 121 to the corresponding side wall surface of the clamping block 12 in an inclined manner. Therefore, when the air duct cover 2 needs to be removed from the rear wall inside the case liner 1, the first hinge rod 33 of the clamping assembly 3 can be moved to one end of the first clamping groove 121, so that the first clamping portion 331 of the first hinge rod 33 can be moved from the slope portion 123 to the outside of the first clamping groove 121, that is, to the outer side wall of the clamping block 12, and then the first clamping portion 331 and the second clamping portion 341 can be separated from the clamping block 12, so that the air duct cover 2 is detached from the rear wall inside the case liner 1.

Referring to fig. 5 and 7, in some embodiments, the second clamping groove 122 is disposed in a strip shape, and the extending direction of the second clamping groove 122 is consistent with the extending direction of the hinge shaft 32. Meanwhile, two ends of the second clamping groove 122 are respectively provided with a slope part 123, and the slope parts 123 extend from the bottom surface of the second clamping groove 122 to the corresponding side wall surface of the clamping block 12 in an inclined manner. Therefore, when the air duct cover 2 needs to be removed from the rear wall inside the case liner 1, the second hinge rod 34 of the clamping assembly 3 can be moved to one end of the second clamping groove 122, so that the second clamping portion 341 of the second hinge rod 34 can be moved from the slope portion 123 to the outside of the second clamping groove 122, that is, to the outer side wall of the clamping block 12, and then the first clamping portion 331 and the second clamping portion 341 can be separated from the clamping block 12, so that the air duct cover 2 is detached from the rear wall inside the case liner 1.

Referring to fig. 7, in some embodiments, the clamping block 12 is integrally formed with the rear wall of the inner portion of the liner 1, and the clamping block 12 may be formed by recessing the rear wall of the liner 1 forward, so that the clamping block 12 is convexly disposed on the rear wall of the inner portion of the liner 1.

Fig. 15 is a schematic view of the structure of fig. 7 in another state.

Referring to fig. 7 and 15, in some embodiments, the first clamping portion 331 and the second clamping portion 341 are disposed opposite to each other at intervals. The first clamping portion 331 and the second clamping portion 341 can be kept spaced apart before the duct cover 2 is mounted inside the cabinet 1. Therefore, when the duct cover 2 is mounted on the rear wall of the cabinet 1, the front end of the clamp block 12 can be inserted between the first clamping portion 331 and the second clamping portion 341, stretching the first clamping portion 331 and the second clamping portion 341, and allowing the elastic member 35 to be stretched. When the first clamping groove 121 on both sides of the clamping block 12 is opposite to the first clamping portion 331 and the second clamping groove 122 is opposite to the second clamping portion 341, the elastic member 35 can retract and reset, and the first clamping portion 331 and the second clamping portion 341 can be respectively clamped and fixed at the first clamping groove 121 and the second clamping groove 122, so that the air duct cover plate 2 is fixed on the rear wall inside the box liner 1.

In some embodiments, the width of the front end of the clamp block 12 is smaller than the width of the rear end of the clamp block 12 in the direction from the first clamp portion 331 toward the second clamp portion 341. At the same time, the corresponding width of the clamp block 12 tapers in the back-to-front direction. Therefore, when the duct cover 2 is mounted on the rear wall of the cabinet 1, the front end of the clamp block 12 can be extended between the first clamping portion 331 and the second clamping portion 341, so that the first clamping portion 331 and the second clamping portion 341 are spread apart, the interval therebetween becomes large, and the elastic member 35 is stretched. When the first clamping portion 331 is disposed opposite to the first clamping groove 121 and the second clamping portion 341 is disposed opposite to the second clamping groove 122, the tension of the elastic member 35 can enable the first clamping portion 331 and the second clamping portion 341 to be respectively clamped and fixed at the first clamping groove 121 and the second clamping groove 122, so as to fix the air duct cover 2 on the rear wall inside the case liner 1, as shown in fig. 15, the state changes from fig. 7.
