A circular-shaped second flange 76 perpendicularly extends in from a circumference of a second end of the sleeve 72. A round through hole 760 is bounded by the second flange 76. A bracket 78 perpendicularly extends from the second flange 76, straddling the through hole 760, away from the first flange 74. The bracket 78 includes a stop board 780, opposite to the through hole 760. Two openings 782 are symmetrically formed on two opposite sides of the bracket 78, communicating with the through hole 760. A receiving portion is defined between the stop board 780 and the through hole 760. Two connecting holes 740 are defined in the first flange 74, adjacent to the sleeve 72, and corresponding to the two connecting portions 13 of the front cover 10. Four positioning portions 742 protrude from the first flange 74, opposite to the second flange 76, corresponding to the four positioning slots 27 of the panel 20. The connecting holes 740 and the positioning portions 742 are arranged in staggered fashion. Four latching portions 720 protrude from an inner surface of the sleeve 72, corresponding to the four grooves 520 of the fixing member 50.
Referring to FIG. 4 and FIG. 5, in assembly, the first resilient member 40 fits about the second sleeve 54 of the fixing member 50, and is accommodated in the circular-shaped slot 58 of the fixing member 50. The clip 44 is engaged in the latching slot 540 of the second sleeve 54 of the fixing member 50. The rotating shaft 31 of the rotating member 30 extends through the second sleeve 54 of the fixing member 50, with the sleeve 35 of the rotating member 30 received between the first sleeve 52 and the first resilient member 40. The second sleeve 54 and the first resilient member 40 are received in the circular-shaped slot 39 of the rotating member 30. The clip 42 of the first resilient member 40 is engaged in the groove 350 of the sleeve 35. The protrusions 352 of the sleeve 35 may be stopped by the corresponding protrusions 522 of the first sleeve 52 of the fixing member 50. The second resilient member 60 is inserted into the through hole 32 from the second terminal 312 of the rotating shaft 31. The combined assembly of the fixing member 50, the first resilient member 40, the second resilient member 60, and the rotating member 30 are attached to the sleeve 72 of the rear cover 70 from the first flange 74. The end wall 56 of the fixing member 50 resists the second flange 76 of the rear cover 70. A first terminal of the second resilient member 60 resists against the stop board 780. The second terminal 312 of the rotating shaft 31 is received in the receiving portion of the bracket 78. The latching portions 720 engage in the corresponding grooves 520 of the fixing member 50. The first terminal 310 of the rotating shaft 31 extends through the through hole 23 of the panel 20. The end wall 37 of the rotating member 30 resists the outer surface of the bottom wall 22 of the receiving portion 21 of the panel 20. The latches 29 engage with an edge of the first flange 74. The positioning portions 742 of the rear cover 70 are engaged in the corresponding positioning slots 27 of the panel 20. The connecting holes 740 are aligned with the corresponding slots 25 of the panel 20. The sleeve 12 of the front cover 10 is received in the receiving portion 21 of the panel 20. The connecting portions 13 pass through the corresponding slots 25 of the panel 20, to engage in the connecting holes 740 of the rear cover 70. The locking portion 15 is received in the through hole 32 of the rotating member 30. The hooks 17 of the front cover 10 resist the corresponding locking blocks 33 of the rotating member 30.
When the front cover 10 is driven to move towards to the panel 20, the resisting surface 176 of each hook 17 resists the connecting surface 336 of a corresponding locking block 33, to drive the rotating member 30 to rotate a little, thereby deforming the first resilient member 40 by engagement between the clip 42 of the first resilient member 40 and the groove 350 of the rotating member 30. The sliding surface 172 of the hook 17 slides along the sliding surface 3321 of the sliding portion 332 of the locking portion 33, opposite to the resisting portion 334, causing the stop surface 175 of the hook 17 to deform the second resilient member 60. When the retaining surface 174 of the hook 17 moves ahead of the resisting surface 3341 of the resisting portion 334 of the locking block 33, the first resilient member 40 restores to drive the rotating member 30 to return back, causing the retaining surface 174 to resist the resisting surface 3341 of the resisting portion 334. Therefore, the front cover 10 with the emblem plate 100 is fixed to the panel 20.
When the emblem plate 100 needs to be replaced, the operation portion defining the plurality of sliding slots 314 of the rotating member 30 can be accessed through the openings 782 of the bracket 78 of the rear cover 70 and rotated. This action drives the resisting portion 334 of each locking block 33 of the rotating member 30 to move away from the retaining surface 174 of a corresponding hook 17 of the front cover 10. Thus the second resilient member 60 is caused to restore to drive the front cover 10 to move away from the rotating member 30. Therefore, only the front cover 10 with the emblem plate 100 need be replaced, which is convenient and cost effective.
Furthermore, the connecting portions 13 of the front cover 10 can rotate 90 degrees in the corresponding slots 25 of the panel 20, by rotating the rear cover 70 and engagement between the connecting portions 13 and the first flange 74 of the rear cover 70. Therefore, the emblem plate 100 is rotated 90 degrees relative to the panel 20. The fixing device for a emblem plate 100 can replace emblem plates and adjust angles of the emblem plates conveniently.
