Description

Technical Field

[0001] The utility model relates to the technical field of profiles for publicity and advertisement, in particular to a conveniently adjustable light box profile. Background Art

[0002] The light box profile is used to fix the promotional billboards. It is convenient to fix the promotional billboards on the wall, and it is convenient to replace them from the light box profile. The light box profile is composed of an upper profile shell, a lower profile shell and a spring. A spring is arranged between the upper profile shell and the lower profile shell. The spring mainly provides elasticity between the upper profile shell and the lower profile shell. If the light box profile is longer, the number of springs installed inside the light box profile must also be increased, and the distance between the springs needs to be adjusted during installation to make the clamping force of the light box profile more uniform. Since the springs are very elastic, people need to manually push the springs to adjust the distance, and pushing the springs is very laborious. Therefore, a light box profile that is easy to adjust is now developed. Utility Model Content

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0016] A light box profile that is easy to adjust, such as Figure 1-5As shown, it includes an upper profile shell 1, a lower profile shell 2, a spring piece 3 and an extrusion assembly. The left part of the upper profile shell 1 is rotatably connected to the lower profile shell 2, and the front and rear sides of the upper left part of the upper profile shell 1 are slidably connected to the spring pieces 3. The lower profile shell 2 is provided with an extrusion assembly, which includes an extrusion plate 7, a wedge-shaped push block 8 and an extrusion rod 9. The right part of the lower profile shell 2 is provided with a second guide hole 12, and the second guide hole 12 is slidably connected to the extrusion rod 9. The left part of the extrusion rod 9 and the right part of the spring piece 3 are extruded and matched. The right part of the lower profile shell 2 is evenly provided with eight first guide holes 11, and the first guide holes 11 are slidably connected to the wedge-shaped push blocks 8. The wedge-shaped push blocks 8 and the extrusion rod 9 are extruded and matched. When the wedge-shaped push block 8 moves down to contact the extrusion rod 9, the extrusion rod 9 will move left to press the spring piece 3. An extrusion plate 7 is provided between the right parts of the wedge-shaped push blocks 8.

[0017] It also includes a deceleration plate 10. The right part of the lower profile shell 2 is evenly provided with the deceleration plates 10 with equal intervals. The extrusion plate 7 and the deceleration plate 10 are extruded and matched. The deceleration plate 10 is used to decelerate the extrusion plate 7.

[0018] It also includes a limiting plate 6, an insertion hole 5 is opened on the upper left part of the upper profile shell 1, a plurality of movable holes 4 are evenly opened on the upper left part of the upper profile shell 1, the limiting plate 6 is connected to the front and rear sides of the left part of the spring plate 3, the limiting plate 6 and the movable hole 4 are slidably connected, and the limiting plate 6 and the insertion hole 5 are slidably connected.

[0019] When using the light box profile that is easy to adjust, since the lengths of the light box profiles are different, some light box profiles that are relatively long need to be installed with multiple spring clips 3 in order to make the clamping force of the light box profile better and the clamping force of the light box better. Therefore, before using the light box profile that is easy to adjust, the position of the spring clip 3 can be installed and adjusted according to the different lengths of the upper profile shell 1 and the lower profile shell 2 of the light box profile. First, manually push the squeezing plate 7 upward, and the squeezing plate 7 drives the wedge-shaped pushing block 8 to push upward. After the wedge-shaped pushing block 8 and the squeezing rod 9 are separated, the squeezing rod 9 is pushed to the right by the spring clip 3, so that the squeezing rod 9 no longer squeezes the spring clip 3, and then the elastic force exerted by the spring clip 3 will be weakened. People can manually pull the left part of the spring piece 3 upwards, and the spring piece 3 will drive the limiting piece 6 and the movable hole 4 to separate, and then the spring piece 3 can be manually moved back and forth to adjust the position of the spring piece 3. After the adjustment, the spring piece 3 can be released, and the spring piece 3 will drive the limiting piece 6 to be re-engaged in the movable hole 4, and then the squeezing plate 7 is manually pushed downward, and the squeezing plate 7 drives the wedge-shaped pushing block 8 to move downward. After the wedge-shaped pushing block 8 contacts the squeezing rod 9, the squeezing rod 9 is pushed to the left, and the squeezing rod 9 will squeeze the right part of the spring piece 3, so that the middle part of the spring piece 3 arches upward. In this way, the elastic force of the spring piece 3 is strengthened, and people will use this easily adjustable light box profile to fix the light box more firmly.
