Detailed Description

To assist understanding of the present invention, exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, and with reference to fig. 2a-2f, a first exemplary embodiment of the present invention will be described. The advertising lamp box comprises a picture 1, a protective cover 2, a lamp tube 3, a light guide plate 4, a back plate 5, a movable frame 6 arranged around the picture 1, a spring piece 7 and angle iron 8; the movable frame 6 comprises 4

independent substrates

61 and 4 corresponding connecting plates 62 distributed along the periphery of the frame; wherein, the base plate 61 is provided with a fixing shaft 611, an open slot 612 for fixing the spring plate 7, a fixing slot 613 for connecting the adjacent base plates 61 through an angle iron 8 therein, a lapping surface 614 for lapping and placing the picture 1 and the protective cover 2 thereon, a receiving space 615 for receiving the lamp tube 3 therein, an opening 616 for receiving the light guide plate 4, and an L-shaped fixing slot 617 for fixing the back plate 5; the connecting plate 62 is provided with a corresponding locking groove 621 engaged with the fixing shaft 611 to rotate the connecting plate 62 relative to the base plate 61, a covering portion 622 for covering the base plate 61, a blocking portion 623 in contact with the protection cover 2, and an opening portion 624 for facilitating opening of the movable frame 6.

As shown in fig. 2a, when assembling the advertising light box for the first time, the lamp 3 is first placed in the receiving space 615 of the substrate 61 along the length direction of the substrate 61, then one end of the light guide plate 4 is inserted into the opening 616 for use in a direction perpendicular to the lamp 3, then another lamp 3 is placed in the receiving space 615 of the substrate on the opposite side in an equal manner, while the other end of the light guide plate 4 is inserted into the opening 616 of the substrate on the opposite side, and then the openings 616 of the substrates on the adjacent sides are respectively received in the opposite directions to the two sides of the light guide plate 4, and the four substrates 61 are assembled together through the angle iron 8. At this time, the picture 1 may be placed on the light guide plate 4, the periphery of the picture 1 may be lapped on the lapping surface 614 of the substrate, the protective cover 2 may be covered on the picture 1, then, the spring plate may be placed in the opening groove 612 of the substrate by means of an installation tool (not shown), the spring plate may be slightly compressed by a force, in this case, the slot 621 of the connection plate 62 may be clamped into the fixing shaft 611 of the substrate 61 from one side, and the slot 621 may be slid along the fixing shaft 612 to completely engage with the spring plate, at this time, the connection plate 62 may be pressed by hand, when the outer corner edge 6211 of the slot 621 contacting with the spring plate 7 moves downward and completely disengages from the spring plate 7, the force applied to the spring plate 7 is reduced, and at the same time, the blocking portion 623 of the connection plate 62 may be tightly clamped on the protective cover 2 to. Finally, the back plate 5 is placed in the L-shaped fixing groove 617 of the base plate 61, and the back plate is fixed by screws.

As shown in fig. 2b and 2c, when the picture 1 needs to be replaced, the opening portion 624 of the connecting plate 62 is pulled down by hand, due to the existence of the locking slot 621 and the fixing shaft 611, the connecting plate 62 will pivot outward at the fixing shaft 611, so that the blocking portion 623 is away from the protection cover 2, and at the same time of the rotation, the outer corner edge 6211 of the locking slot 621 will press the spring plate 7 inward, and will stop when the connecting plate 62 rotates to a certain angle (for example, 70 degrees away from the protection cover), and since the corner edge 6211 will be away from the contact spring plate 7, the connecting plate 62 will not rebound automatically. When the 4 peripheral connecting plates 62 on the movable frame 6 are opened, the protective cover 2 is completely exposed in a non-blocking state, at this time, the protective cover 2 can be easily taken out, then the picture 1 is taken out and replaced, the protective cover 2 is put back, then the opening part 624 of the connecting plate 62 is only required to be pushed back slightly, the spring piece 7 can be pressed inwards by the outer corner edge 6211 of the clamping groove 621, when the corner edge 6211 rotates to the lower side of the spring piece 7, the connecting plates 62 are quickly returned due to the reaction force of the spring piece 7, so that the blocking part 623 contacts the protective cover 2, and the picture is fixed inside.

As shown in fig. 3, a cross-sectional view showing a use state of the second embodiment of the present invention is shown. The difference between this embodiment and the first embodiment is that the front and back sides of the movable frame 6 can display pictures, mainly because the structure of the base plate 61 of the movable frame 6 is symmetrically arranged, and the back plate 5 and the L-shaped fixing groove 617 are eliminated. Accordingly, the number of the connecting plates 62 is increased, and the light guide plate 4 and the lamp 3 are not increased to achieve the same effect.

As shown in fig. 4, a cross-sectional structure of a connecting plate of a third embodiment of the present invention is shown. The difference from fig. 2e is that the shape of the connecting plate 62 at the blocking portion 623 and the opening portion 624 is changed, but they play the same role as the first embodiment.

Those skilled in the art should appreciate that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
