Description

Technical Field

[0001] This utility model relates to the field of billboard technology, specifically to an adjustable-size billboard. Background Technology

[0002] Billboards are a medium for conveying advertising information and are widely used in commercial activities and daily life. There are many types and forms of billboards, including illuminated signs, inkjet-painted signs, lightbox signs, bulletin board signs, pillar signs, directional signs, and promotional signs.

[0003] Patent CN219936652U discloses an adjustable-size billboard, which includes a base plate, two support tubes, a fixed display plate, two rotating display plates, and a drive device. The base plate is horizontally fixed to the ground; the support tubes are vertically connected above the base plate; the fixed display plates are vertically connected above the base plate and located between the two support tubes. The drive device rotates the display plates in conjunction with the fixed display plates, thereby adjusting the display area of ​​the billboard.

[0004] However, the current device only adjusts the size of the billboard by rotating the display panel. Regardless of whether the display panel is fixed or rotating, the size of the two display panels remains constant. Therefore, the size of the advertising cloth must meet the size of either the fixed or rotating display panel. If the advertising cloth is of a different size, it will be difficult to use the billboard for display. To address this issue, an adjustable billboard is proposed to solve the problem that existing billboards cannot adjust their size according to the size of the advertising cloth.

[0014] (III) Beneficial Effects

[0015] 1. This adjustable billboard allows the second billboard to rotate 180 degrees via a control slot. Then, based on the size of the advertising cloth, the distance between the two second billboards is adjusted using a limiting shaft and the limiting slots and openings within the fixing plate. After adjusting the first display slot to the appropriate size, the advertising cloth is pasted on. The position of the second billboard is limited by nuts and external threads. Then, other display and promotional content is pasted into the second display slot, achieving the purpose of billboard size adjustment and solving the problem that existing billboards cannot adjust their size according to the size of the advertising cloth.

[0016] 2. This adjustable billboard can be installed in the desired position via the base plate. Then, according to the required display height, the knob, in conjunction with the bearing, drives the bidirectional lead screw to rotate, which in turn moves the adjusting block in the adjusting groove toward the center. Then, under the action of the limiting block outside the limiting rod and the adjusting plate connected by the rotating shaft, the second billboard can be moved up to the appropriate position, thus achieving the purpose of adjusting the height of this adjustable billboard and improving its practicality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figure 1-4An adjustable-size billboard includes a base plate 1, a first billboard 4 on the top of the base plate 1, grooves 2 symmetrically formed on the bottom of the first billboard 4, a support column 3 inside the groove 2, two fixing plates 5 fixedly connected to one end of the first billboard 4, two second billboards 6 symmetrically arranged between the two fixing plates 5, a limiting shaft 7 fixedly connected inside the second billboard 6, a limiting groove 8 formed on the bottom of the top fixing plate 5, a slot 9 formed through the top of the bottom fixing plate 5, a nut 10 and an external thread 11 on the outer ring of the limiting shaft 7, a first display groove 12 formed on one end of the first billboard 4, a second display groove 13 formed on the end of the second billboard 6 facing the first billboard 4, an adjustment mechanism 14 on the top of the base plate 1, and control slots 15 formed on opposite sides of the two second billboards 6.

[0024] Furthermore, the support column 3 is fixedly connected to the base plate 1, the limiting shaft 7 passes through the second billboard 6 and its top is located in the inner cavity of the limiting groove 8, the bottom of the limiting shaft 7 passes through the groove 9 and the two are slidably connected.

[0025] Furthermore, the nut 10 is located at the bottom of the bottom fixing plate 5, allowing the second billboard 6 to slide or rotate between the fixing plates 5.

[0026] Furthermore, the adjustment mechanism 14 includes an adjustment groove 141 formed at the bottom of the first billboard 4, with adjustment blocks 142 symmetrically arranged in the inner cavity of the adjustment groove 141, and a limit rod 143 fixedly connected between the support columns 3, with a limit block 144 slidably arranged on the outer ring of the limit rod 143.

[0027] Furthermore, two adjusting plates 145 are cross-shapedly arranged at the bottom of the first billboard 4. The adjusting plates 145 are connected by a rotating shaft 146, and the adjusting plates 145 are rotatably connected to the adjusting block 142 and the limiting block 144.

[0028] Furthermore, the inner cavity of the adjusting groove 141 is rotatably equipped with a bidirectional lead screw 147. The bidirectional lead screw 147 passes through the first billboard 4 and is rotatably connected by a bearing at the intersection. The bidirectional lead screw 147 passes through two adjusting blocks 142 and the two are threaded together. A knob 148 is fixedly connected to one end of the bidirectional lead screw 147. The billboard can be installed in the required position through the base plate 1. Then, according to the height requirements of the display and advertising, the knob 148 is used in conjunction with the bearing to drive the bidirectional lead screw 147 to rotate, thereby driving the adjusting blocks 142 in the adjusting groove 141 to move towards the center. Then, under the action of the limiting block 144 outside the limiting rod 143 and the adjusting plate 145 connected to the rotating shaft 146, the first billboard 4 can be moved up to the appropriate position, realizing the purpose of adjusting the height of this size adjustable billboard and improving its practicality.

[0029] Working principle: When using this size-adjustable billboard, the second billboard 6 is rotated 180 degrees by controlling the slot 15. Then, according to the size of the advertising cloth, the distance between the two second billboards 6 is adjusted by the limiting shaft 7 and the limiting groove 8 and slot 9 in the fixing plate 5. After adjusting the first display slot 12 to the appropriate size, the advertising cloth is pasted. The position of the second billboard 6 is limited by the nut 10 and the external thread 11. Then, other display and promotional content is pasted into the second display slot 13, thus achieving the purpose of billboard size adjustment. This solves the problem that existing billboards are difficult to adjust their size according to the size of the advertising cloth. While achieving the purpose of size adjustment through the first billboard 4 and the second billboard 6, different advertising cloths with different content can be pasted or placed to improve the display effect of this billboard. At the same time, when not displaying or moving and transporting this billboard, the second display slot 13 in the second billboard 6 is rotated to face the first display slot 12 and limited by the nut 10 and the external thread 11, which facilitates the protection of the display and promotional content in the first display slot 12 and the second display slot 13.
