[0006] A modular spliced advertising light box frame includes a frame body, a movable door frame and a protective cover. The movable door frame is movably installed on the front surface of the frame body, the protective cover is movably sleeved at the lower end of the frame body, and a positioning rod is movably embedded inside the lower end of the frame body.

[0007] Preferably, a closing groove is opened on the front surface of the frame body, a through hole is opened on the lower surface of the frame body, lifting grooves are longitudinally opened on both inner surfaces of the through hole, and moving grooves are longitudinally opened on both side surfaces of the frame body near the lower end.

[0008] Preferably, guide rods are fixedly installed inside the moving grooves and the lifting grooves, springs are sleeved on the surfaces of the guide rods, and the through hole is communicated with the closing groove.

[0009] Preferably, sleeve blocks are fixedly installed on both inner surfaces of the protective cover and above, an extending port is opened on the lower surface of the protective cover and near the front, and the sleeve blocks are movably sleeved on the surfaces of the guide rods inside the moving grooves.

[0010] Preferably, a plug post is fixedly installed on the upper surface of the positioning rod, a handle is fixedly installed in the middle of the lower surface of the positioning rod, and sliding sleeves are fixedly installed on both ends of the positioning rod.

[0011] Preferably, the positioning rod is movably embedded in the through - opening, the sliding sleeve is movably sleeved on the surface of the guide rod inside the lifting groove, and the number of the inserting columns is four.

[0012] Preferably, a slot is formed on the lower surface of the movable door frame, the inserting column is embedded in the slot, and the movable door frame is movably connected to the frame body through a hinge.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by setting the frame body, the movable door frame, the protective cover and the positioning rod to cooperate with each other, when it is necessary to open the movable door frame and maintain the components inside the frame body, the staff pushes the protective cover with hand. When the protective cover moves upward, the spring inside the moving groove will be compressed. When the protective cover rises to a certain height, the handle of the positioning rod will protrude from the outlet of the protective cover. At this time, the staff holds the handle and pulls it down, so that the inserting column of the positioning rod can be withdrawn from the slot of the movable door frame. At this time, the movable door frame can be directly flipped open, which is convenient for the staff to repair and maintain the inside of the light box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieving purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0022] As shown Figures 1-5 is a modular spliced advertising light box frame, including a frame body 1, a movable door frame 2 and a protective cover 3. The movable door frame 2 is movably installed on the front surface of the frame body 1, the protective cover 3 is movably sleeved at the lower end of the frame body 1, and a positioning rod 4 is movably embedded inside the lower end of the frame body 1.

[0023] A closing groove 101 is opened on the front surface of the frame body 1, a through opening 102 is opened on the lower surface of the frame body 1, lifting grooves 103 are longitudinally opened on both inner side surfaces of the through opening 102, and moving grooves 106 are longitudinally opened on both side surfaces of the frame body 1 and near the lower end. The through opening 102 can accommodate the positioning rod 4 when not in use; guide rods 104 are fixedly installed inside the moving grooves 106 and the lifting grooves 103, springs 105 are sleeved on the surfaces of the guide rods 104, and the through opening 102 communicates with the closing groove 101; on both inner side surfaces of the protective cover 3 and above, sleeve blocks 301 are fixedly installed, and an extension opening 302 is opened on the lower surface of the protective cover 3 and near the front.
