Description

Technical Field

[0001] This utility model relates to the field of signage technology, specifically a retractable acrylic sign. Background Technology

[0002] In the field of signage technology, signs, as a key carrier for conveying information and issuing warnings, are widely used in various scenarios such as traffic roads, construction areas, commercial venues, and public facilities. Their functionality, practicality, and flexibility of use directly affect the efficiency of information transmission and the effectiveness of warnings.

[0003] With the diversification of application scenarios and the refinement of usage needs, the market has put forward higher requirements for the structural design, functional expansion and material selection of signs. They not only need to have clear information display capabilities, but also need to adapt to the installation conditions, space constraints and dynamic warning needs in different scenarios. Among them, acrylic material has gradually become one of the mainstream materials for the body of signs due to its advantages such as being lightweight, environmentally friendly, having good light transmission and strong weather resistance.

[0004] Most existing acrylic signs adopt a fixed structure design, meaning the sign body and the mounting bracket are integrated and fixedly connected, making it impossible to extend or retract according to actual usage needs. In installation scenarios with limited space, fixed-size signs are easily restricted by the environment and cannot be fully extended to achieve effective warning. In addition, the existing signs have insufficient protective structure design, and their internal transmission components (such as gears, slide rails, and grooves) are easily exposed, making them susceptible to external impacts and reducing the practicality of the equipment.

[0005] In view of this, we propose a stretchable acrylic sign. Utility Model Content

[0006] The purpose of this utility model is to provide a retractable acrylic sign to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A retractable acrylic sign includes a support frame, on which a telescopic component is mounted. The telescopic component includes:

[0009] An asynchronous motor is fixedly installed on the outer wall of the bracket. A drive gear is fixedly installed at the output end of the asynchronous motor. A central column is fixedly installed at the center of the bracket. A rotating disk is rotatably installed on the outside of the central column through bearing components.

[0010] A driven gear is fixedly installed on the outside of the rotating disk. The driven gear meshes with the driving gear. A through arc-shaped groove is opened on the rotating disk. A T-shaped frame is slidably installed inside the bracket via a slide rail.

[0011] A sliding rod is fixedly installed on the T-shaped frame. The sliding rod slides and fits inside the arc-shaped groove. A conical block is fixedly installed on the outside of the sliding rod. The sign body is fixedly installed on the T-shaped frame.

[0012] In a further embodiment, multiple sets of the arc-shaped groove, T-shaped frame, sliding rod, conical block, and sign body are provided, thereby enabling the installation of various types of warning signs.

[0013] In a further embodiment, multiple sets of the aforementioned arc-shaped grooves, T-shaped frames, sliding rods, conical blocks, and sign bodies are arranged in an equally spaced circular array with the center of the circular cross-section of the rotating disk as the array center.

[0014] In a further embodiment, the sign body is made of acrylic material, which is lighter and more environmentally friendly.

[0015] In a further embodiment, the bracket is also provided with an auxiliary component, which includes a mounting base located outside the bracket. A servo geared motor is fixedly mounted on the outside of the mounting base, and a rotating shaft is fixedly mounted on the output end of the servo geared motor.

[0016] In a further embodiment, the rotating shaft is rotatably mounted on the mounting base via bearing components, and the rotating shaft is fixedly connected to the outer wall of the center of the bracket for better warning.

[0017] In a further embodiment, a protruding column is fixedly installed on the outside of the central column, and a disc is fixedly installed on the protruding column. The circular cross-sections of the disc and the rotating disk are coaxial, thus providing better protection.

[0018] Compared with the prior art, this utility model provides a retractable acrylic sign, which has the following advantages:

[0019] 1. This retractable acrylic sign, designed for better warning, incorporates a telescopic component. When the asynchronous motor on the support is activated, the drive gear rotates, which in turn drives the driven gear, causing the rotating disc to rotate outside the central column. This causes the arc-shaped groove to rotate synchronously, pushing the sliding rod on the T-shaped frame to move synchronously within the arc-shaped groove. The conical block acts as a limit, and the forward and reverse operation of the asynchronous motor allows multiple sign bodies to retract and expand synchronously, thus enhancing their warning effect.

[0020] 2. To improve the practicality of this retractable acrylic sign, auxiliary components are incorporated into the mounting base to install the sign at the target location. When the servo reduction motor is activated, the rotating shaft rotates, thereby driving the retractable components to rotate, thus better fulfilling the warning function. In conjunction with the protruding pillars and discs, the holes and grooves on the rotating disc are shielded to prevent direct impact, thereby improving the practicality of the sign.

[0032] Please see Figures 1-5 This utility model provides a technical solution:

[0033] A retractable acrylic sign includes a support frame 1.

[0034] In one embodiment of this utility model, a telescopic component 2 is provided on the bracket 1. The telescopic component 2 includes an asynchronous motor 21, which is fixedly installed on the outer wall of the bracket 1. A drive gear 22 is fixedly installed at the output end of the asynchronous motor 21. A central column 23 is fixedly installed at the center of the bracket 1. A rotating disk 24 is rotatably installed on the outside of the central column 23 via bearing components. A driven gear 25 is fixedly installed on the outside of the rotating disk 24 and meshes with the drive gear 22. A through arc-shaped groove 26 is provided on the rotating disk 24. A T-shaped frame 27 is slidably installed inside the bracket 1 via a slide rail. A slide rod 28 is fixedly installed on the T-shaped frame 27. The sliding rod 28 slides and fits inside the arc-shaped groove 26. A conical block 29 is fixedly installed on the outside of the sliding rod 28. The sign body 210 is fixedly installed on the T-shaped frame 27. In addition, there are five sets of arc-shaped groove 26, T-shaped frame 27, sliding rod 28, conical block 29 and sign body 210, so that various types of warning signs can be set. In addition, the five sets of arc-shaped groove 26, T-shaped frame 27, sliding rod 28, conical block 29 and sign body 210 are all arranged in a circumferential array with the center of the circular cross section of the rotating disk 24 as the array center. Furthermore, the sign body 210 is made of acrylic material, which is more lightweight and environmentally friendly.

[0035] In this embodiment, the asynchronous motor 21 pre-installed on the bracket 1 is started. After the asynchronous motor 21 is powered on, its output drives the drive gear 22 to rotate at a stable speed. Since the drive gear 22 is meshed with the driven gear 25 fixed outside the rotating disk 24, the rotation of the drive gear 22 will directly drive the driven gear 25 to rotate synchronously, thereby driving the rotating disk 24 connected to the driven gear 25 to rotate around the central column 23 fixed in the center of the bracket 1 (the rotation is smoothed by bearings to reduce friction loss). When the rotating disk 24 rotates, the through arc-shaped groove 26 on its surface will move synchronously with the rotating disk 24. The sliding rod 28, which is slidably attached inside the arc-shaped groove 26, will slide along the inner wall of the arc-shaped groove 26 under the trajectory constraint of the arc-shaped groove 26. During this process, the conical block 29 fixed outside the sliding rod 28 will be tightly attached to the inner wall of the arc-shaped groove 26, which on the one hand restricts the radial displacement of the sliding rod 28 in the arc-shaped groove 26 and prevents the sliding rod 28 from detaching. The arc-shaped groove 26 tracks the track, and the conical structure reduces sliding friction, ensuring stable movement of the slide rod 28. When the asynchronous motor 21 rotates forward, the driving gear 22 drives the driven gear 25 and the rotating disk 24 to rotate forward. The arc-shaped groove 26 pushes the slide rod 28 and the T-shaped frame 27 to slide outward along the inner slide rail of the bracket 1, thereby driving the sign body 210 fixed on the T-shaped frame 27 to expand outward synchronously. When the asynchronous motor 21 rotates in reverse, the rotating disk 24 rotates in the opposite direction, and the arc-shaped groove 26 pulls the slide rod 28 and the T-shaped frame 27 to slide inward along the slide rail. The sign body 210 contracts inward synchronously. Since there are five sets of arc-shaped groove 26, T-shaped frame 27, slide rod 28, conical block 29 and sign body 210, and they are arranged in an equally spaced circular array with the center of the circular cross section of the rotating disk 24 as the array center, the five sets of components will move synchronously under the drive of the asynchronous motor 21, realizing the synchronous expansion and contraction of multiple sets of sign bodies 210, ensuring uniform coverage of the warning range and improving the warning effect.

[0036] In one embodiment of this utility model, the bracket 1 is further provided with an auxiliary component 3, which includes a mounting base 31. The mounting base 31 is disposed outside the bracket 1, and a servo geared motor 32 is fixedly mounted on the outside of the mounting base 31. A rotating shaft 33 is fixedly mounted on the output end of the servo geared motor 32. In addition, the rotating shaft 33 is rotatably mounted on the mounting base 31 through a bearing component. The rotating shaft 33 is fixedly connected to the outer wall of the center of the bracket 1 for better warning. In addition, a protruding column 34 is fixedly mounted on the outside of the central column 23, and a disc 35 is fixedly mounted on the protruding column 34. The circular cross-section centers of the disc 35 and the rotating disc 24 are coaxial for better protection.

[0037] In this embodiment, to improve the installation adaptability and safety of the sign body 210, the mounting base 31 in the auxiliary component 3 is fixedly connected to the target installation location (such as a wall, column, etc.) through a preset mounting hole, thereby stably installing the entire sign device at the target location to meet the installation requirements in different scenarios. The servo reduction motor 32 fixed externally to the mounting base 31 is activated. After the servo reduction motor 32 is powered on, its output end drives the rotating shaft 33 to rotate (the rotating shaft 33 is rotatably mounted on the mounting base 31 through bearing components to ensure rotational stability). Since the end of the rotating shaft 33 furthest from the servo reduction motor 32 is fixedly connected to the outer wall of the center of the bracket 1, the rotation of the rotating shaft 33 directly drives the bracket 1 and the telescopic component 2 on the bracket 1 to rotate synchronously, thereby driving the telescopic component... The sign body 210 on component 2 rotates slowly in sync with the bracket 1. The servo reduction motor 32 stops running and the position of the rotating shaft 33 is fixed by the self-locking function of the servo motor. At the same time, a disc 35 is fixedly installed on the top of the protruding column 34 (set along the axial direction of the central column 23) fixed outside the central column 23. The disc 35 and the circular cross-section center of the rotating disk 24 are kept coaxial, and the diameter of the disc 35 is slightly larger than the diameter of the rotating disk 24. When the rotating disk 24 rotates or the sign device is subjected to external impact, the disc 35 will shield the exposed structures such as the arc groove 26, hole groove and slide rod 28 on the rotating disk 24, so as to prevent external objects (such as foreign objects or collision objects) from directly hitting these key components, reduce the risk of component damage, and improve the practicality of the sign body 210.

[0038] All electrical components mentioned in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the asynchronous motor 21 and the servo geared motor 32. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
