Detailed Description

In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.

Example 1:

As shown in fig. 1-7, the utility model discloses a folding display screen, which comprises a bracket 1, a system box body 2 and at least two display screen box bodies 3, wherein the two display screen box bodies 3 are connected through a hinge 11, and the joint of the hinge 11 is a folding part; one of the back of two display screen box 3 that hinge 11 connects sets up slide rail 12 of vertical direction slide rail 12 is last to slide and is provided with rack 9, rotates between slide rail 12 and display screen box 3 and is connected with gear 8, gear 8 and rack 9 meshing are provided with operation wheel 4 on gear 8, are provided with connecting rod 7 on rack 9, rotate through the round pin axle between the tip of connecting rod 7 and the rack 9 and be connected, the other end of connecting rod 7 is provided with connecting rod seat 10 through the round pin axle, connecting rod seat 10 is fixed in the back of another display screen box 3 in two display screen box 3 that hinge 11 connects.

Wherein the hinge 11 has a straight structure. The hinge 11 is a commercially available product, and has a known structure, as shown in fig. 8 and 9, and mainly includes hollow cylinders at two ends and connecting pieces connected to each other, the unfolded state is in a straight structure, the folding angle is 180 °, and a certain gap is formed between the two hollow cylinders after folding, and the specific structure is not described herein.

In this embodiment, the display screen boxes 3 are four, wherein the upper two display screen boxes 3 are connected by a plugging screw, the lower two display screen boxes 3 are also connected by a plugging screw, and the middle two display screen boxes 3 are connected by a hinge 11. Meanwhile, the sliding rail 12, the gear 8 and the like are arranged on the back of the second display screen box body 3 from bottom to top, so that the upper two display screen box bodies 3 can be folded relative to the lower two display screen box bodies 3 only by operating the back of the second display screen box body 3 in the operation process. The operation is simple and convenient. The specific structures and internal structures of the display screen case 3, the system case 2, the frame 1 and the like are all known structures, and are not limited herein.

In a state where the display screen case 3 is naturally unfolded, the gear 8 is engaged with the upper end of the rack 9. Before transportation, the operation wheel 4 can be rotated, at this moment, the gear 8 rotates, the rack 9 rises, then rack 9 promotes connecting rod 7 upwards, under the connecting rod 7 effect, two display screen box 3 of top are buckling forward, hinge 11 is folding, when rack 9 pushes away to the top, connecting rod 7 is in the horizontal state basically, and two display screen box 3 of top then rotate 180, turn over to the side of two display screen box 3 of below, and the display surface of four display screen box 3 all is located the inboard of display screen box 3, so the condition of collision LED lamp can not appear in the transportation. The maximum folding angle of the hinge 11 is 180 degrees, so that the folding angle of the display screen box body 3 can be limited, meanwhile, the folding angle of the display screen box body 3 can be limited by the length of the rack 9, and the two are matched, so that the folding process is higher in safety and stability. The operating wheel 4 is driven to rotate by the gear 8, and the operating wheel 4 is manually operated, however, in other embodiments, other electric driving modes, such as an electric motor, are also possible. The connecting rod 7 has certain radian or buckling, selects according to actual demand, and when rack 9 pushes up connecting rod 7, can make display screen box 3 be in the folded condition, and when rack 9 was pulled down connecting rod 7, can make display screen box 3 be in the state of expanding.

The back of the display screen box body 3 provided with the gear 8 is provided with a connecting frame 6, and the slide rail 12 and the gear 8 are both arranged on the connecting frame 6; the two ends of the connecting frame 6 extend to the display screen box body 3 connected with the connecting rod seat 10, the connecting wheels 5 are rotatably arranged at the two ends of the connecting frame 6, screw rods are arranged on the connecting wheels 5, screw holes are formed in the display screen box body 3 at the corresponding positions of the connecting wheels 5, and the screw rods on the connecting wheels 5 are matched and connected with the screw holes in the display screen box body 3. The connecting frame 6 is arranged at the back of the display screen box body 3, and the sliding rail 12, the gear 8 and the like are arranged on the connecting frame 6, so that the influence of the folding component on the display screen box body 3 is small, and the display screen box body is convenient to assemble. In addition, two ends of the connecting frame 6 extend to the display screen box body 3 above and are fixedly connected with the display screen box body 3 through a screw on the connecting wheel 5. So after the display screen box 3 is unfolded, the fixed connection between the display screen box 3 at two ends of the hinge 11 is realized through the screw rod of the fifth wheel 5, and the locking state of the fifth wheel 5 can be realized through the design of the screw rod length of the fifth wheel 5, so that the display screen box 3 can be in the same plane, and the connection effect of the display screen box 3 is ensured.

A screw hole is formed in the sliding rail 12, a locking wheel 13 is arranged on the sliding rail 12, a screw rod of the locking wheel 13 is matched with the screw hole, and the screw rod of the locking wheel 13 abuts against the rack 9.

The screw rod of the locking wheel 13 can prop against the rack 9 in a locking state, so that the rack 9 is limited to move in the sliding rail 12, and the folding position or the unfolding position of the display screen box 3 is positioned, so that the display screen box 3 is stable and reliable in the carrying process or the using process.
