Description

Technical Field

[0001] This utility model relates to the field of advertising display technology, specifically a rotatable electronic screen. Background Technology

[0002] The drive and maintenance structure of a rotatable electronic screen is a core component used to control the rotation of the display screen. In existing technologies, the most common method is to directly fix the motor or drive mechanism inside the base and achieve the rotation function through a closed structure.

[0003] Such designs suffer from cumbersome maintenance: since drive components (such as motors) are usually hidden inside the base, maintenance requires removing a large number of housing screws or disassembling the entire base, which is time-consuming and can easily damage surrounding structures; at the same time, the connection between the display screen and the base is mostly rigidly fixed, and common rotating structures often rely on complex gear sets or non-removable hinges, which makes it difficult to quickly separate the display screen from the drive components, making it difficult to directly access the motor or guide mechanism during maintenance; in addition, the protective cover design of existing equipment is mostly an integrated closed structure, and the common locking method is mostly bolts or buckles, which is inconvenient to open and close and prone to loosening after repeated disassembly, further increasing the difficulty of maintenance. Therefore, a rotatable electronic screen is proposed to solve the above-mentioned problems. Utility Model Content

[0024] Please see Figure 1-3 A rotatable electronic screen includes a base 1, a display screen 2, a connecting rod 3, and a sliding assembly. The display screen 2 is located directly above the base 1, and the two are connected by the connecting rod 3. The top end of the connecting rod 3 is bolted to the middle of the bottom end of the display screen 2, and the bottom end of the connecting rod 3 passes through the top of the base 1 and is fixedly installed to the output end of a motor 6 installed inside the base 1. A sliding assembly is provided inside the base 1.

[0025] The sliding assembly includes a sliding seat 5, two sliders 7, and two guide posts 10. The sliding seat 5 is located in the middle of the base 1, and its two sides are fixedly connected to the two sliders 7 respectively. The sliding seat 5 and the two sliders 7 are integrally formed. Inside the base 1, a horizontal groove 4 is opened at the position corresponding to the sliding seat 5 and the two sliders 7. The two guide posts 10 are horizontally fixedly installed inside the groove 4, and the two ends of the guide posts 10 are bolted to the inner wall of the groove 4. The guide posts 10 are slidably connected after being inserted into the sliding seat 5. The two sliders 7 are slotted on the side away from each other, and multiple guide wheels 8 are installed in the grooves.

[0026] In this embodiment, a rectangular groove is provided at the top of the sliding seat 5, and a motor 6 is fixed in the rectangular groove with bolts. The output end of the motor 6 is fixedly installed to the bottom end of the connecting rod 3.

[0027] In this embodiment, multiple vertical shafts are fixedly installed in the groove opened on the side of the slider 7. The number of shafts is the same as the number of guide wheels 8, and the guide wheels 8 are rotatably connected to the shafts after being inserted.

[0028] In this embodiment, a guide groove 9 is provided in the middle of the inner wall of the slide groove 4. The guide wheel 8 extends beyond the side of the sliding seat 5 towards the inner wall of the slide groove 4, and this end of the guide wheel 8 is located in the guide groove 9 and is slidably connected with the guide groove 9, thereby assisting the sliding of the sliding seat 5.

[0029] In this embodiment, a T-shaped groove 17 is provided on the top of the base 1, located on one side of the connecting rod 3 and directly above the slide groove 4. Two cover plates are engaged in the T-shaped groove 17, forming a T-shape, and are respectively the first cover plate 11 and the second cover plate 12.

[0030] In this embodiment, the two cover plates are hinged together. The second cover plate 12 is close to the connecting rod 3, and its side facing the connecting rod 3 is set with an arc-shaped groove. An arc-shaped rubber block 13 is fixedly installed in the arc-shaped groove. The arc-shaped rubber block 13 is made of elastic material and has the characteristic of self-recovery after being deformed by pressure. When the second cover plate 12 is closed, the arc-shaped rubber block 13 is deformed by the side of the connecting rod 3 and fits against its surface to form a flexible snap, ensuring the stability of the closed state of the cover plate. When the second cover plate 12 is rotated to open, the arc-shaped rubber block 13 is disengaged from the connecting rod 3 by elastic recovery force, avoiding hard friction damage. At the same time, its arc-shaped contour is adapted to the rotation trajectory of the connecting rod 3, further reducing the opening and closing resistance and improving the smoothness of operation.

The plug is inserted into the lock opening of the lock plate 14, and a titanium wire lock 16 is installed in the arc-shaped through hole.

[0033] Beneficial effects: This rotatable electronic screen slides horizontally along the guide post 10 within the slide groove 4 via the sliding seat 5 and two sliders 7. Combined with the limiting design of the guide wheel 8 on the side of the slider 7 embedded in the guide groove 9 on the inner wall of the slide groove 4, the stability of the display screen 2 when the motor 6 drives the connecting rod 3 to rotate is ensured. At the same time, the first cover plate 11 and the second cover plate 12 are connected by a split hinge in the T-shaped groove 17 at the top of the base 1. With the quick unlocking structure of the locking plate 14 and the locking seat 15 through the titanium wire lock 16, it is possible to directly expose the slide groove 4 and the sliding seat 5 simply by removing the titanium wire lock 16 and flipping the cover plate. Pushing the sliding seat 5 drives the motor 6 to slide out of the base 1 along the guide post 10 for maintenance, which solves the cumbersome problem of traditional electronic screens requiring the complete disassembly of the base 1 or the destructive removal of the cover plate.

[0034] Working principle: When maintenance is required, first remove the titanium wire lock 16 on the lock seat 15 to release the insertion constraint between the lock plate 14 and the plug. Then flip the hinged second cover plate 12 and first cover plate 11 to expose the T-shaped groove 17 on the top of the base 1 and the slide groove 4 below. At this time, push the sliding seat 5 to slide outward along the guide post 10, which will drive the motor 6 and connecting rod 3 to move out of the base 1 as a whole. At the same time, the guide wheel 8 of the slider 7 rolls along the guide groove 9 to assist the sliding of the sliding seat 5 until the sliding seat 5 is completely exposed for maintenance.
