Technical Field

[0001] This invention belongs to the technical field of hanging display equipment, specifically an adjustable banner hanging device. Background Technology

[0002] Banners are widely used as a low-cost yet effective form of advertising. Existing banner hanging methods typically involve suspending the banner at both ends with ropes. However, this often results in the banner sagging in the middle due to loose ropes, affecting its aesthetics and advertising effectiveness. Especially in stretch-hanging banners, the banner cannot be properly extended horizontally, and repeated stretching can easily lead to tearing. Therefore, it is necessary to provide an adjustable banner hanging device to solve the problems mentioned in the background section. Summary of the Invention

[0020] Please see Figure 1 In this embodiment of the invention, an adjustable banner hanging device includes: a support frame 1 with multiple rollers symmetrically fixed below it; an adjusting bracket 2 installed in the middle of the upper surface of the support frame 1; the adjusting bracket is V-shaped; and hanging components 3 are symmetrically arranged on the left and right sides of the adjusting bracket 2. The hanging components 3 are used to suspend the banner. An extension mechanism 4 is also suspended above the adjusting bracket 2 to extend the center of the banner, thereby avoiding excessive stretching of the banner and preventing tearing.

[0021] In this embodiment, the adjusting bracket 2 includes: a positioning seat 21 fixed on the support frame 1; a rotating shaft 22 rotatably mounted on the center of the positioning seat 21; a shaft disc 23 fixed to the upper end of the rotating shaft 22; connecting frames 24 symmetrically hinged to the shaft disc 23; main suspensions 25 rotatably connected to each connecting frame 24; a telescopic adjusting rod 27 hinged to the shaft disc 23; one end of the telescopic adjusting rod 27 rotatably connected to the main suspension 25; a support rod 26 rotatably adjustable at the upper end of the main suspension 25; a transmission gear sleeved on the rotating shaft 22; and an external motor (not shown in the figure) mounted on the positioning seat 21. The output end of the external motor meshes with the transmission gear through gear engagement, meaning that the external motor can continuously or intermittently drive the shaft disc to rotate, thereby enabling the banner to be hung and displayed at multiple angles, improving the display effect.

[0022] In a preferred embodiment, the suspension assembly 3 includes: an outer frame 31, one side of which is rotatably connected to the adjusting bracket 2; a sliding frame 32 is vertically fixed on the outer frame 31; two connecting members 33 are slidably arranged on the sliding frame 32; a bidirectional telescopic rod 34 is fixed on the outer frame 31; the telescopic ends of the bidirectional telescopic rod 34 are respectively connected to the connecting members 33, thereby enabling adaptive suspension of banners of different lengths and widths; two guide rods 35 are horizontally mounted on the sliding frame 32 on the left side; one end of each guide rod 35 is slidably connected to the sliding frame 32 on the right side; and the extension mechanism 4 is slidably mounted on the guide rods 35. That is, the outer frames on both sides can always be in a parallel state under the connection of the guide rods. When the telescopic adjusting rod on one side of the adjusting bracket retracts and the corresponding telescopic adjusting rod on the other side extends, the banner can be erected at an angle and suspended in a swing-adjustable manner under the continuous adjustment of the adjusting bracket.

[0023] In this embodiment, the connecting member 33 uses a clamping plate structure or a shaft insertion structure to position the four corners of the banner. The clamping plate structure mainly positions the displacement of the four corners of the banner through positioning clamps, while the shaft insertion structure uses a positioning shaft inserted through the positioning holes of the banner to suspend and position it.

[0024] In this embodiment, the extension mechanism 4 includes: a drive seat 41, which is slidably disposed on the guide rod 35 in the suspension assembly 3. Connecting frames 42 are symmetrically arranged on both sides of the drive seat 41. The connecting frames 42 are connected to the drive seat 41 through an electric telescopic rod 43. A frame plate 44 is connected to one side of the connecting frame 42 through a spring rod. A positioning roller 45 is rotatably connected to the frame plate 44. Multiple extension rollers 5 are distributed on the outer periphery of the positioning roller 45.

[0025] In this embodiment, an outer frame rod 46 is rotatably connected to the drive base 41. The cross-section of the outer frame rod 46 is an inverted V-shaped structure, and it is telescopic at both ends. The two ends of the outer frame rod 46 are respectively connected to the frame plate 44. A rotating disk 47 is rotatably mounted on the drive base 41. The rotating disk 47 is connected to the outer frame rod 46 through a support rod. Especially in the case of banner hanging for advertising, the rotating disk can push the frame plates on both sides to slide through the outer frame rod while rotating continuously, so that the positioning rollers on the frame plate can provide a continuous undulating effect for the banner, thereby improving its eye-catching display.

[0026] In a preferred embodiment, the extending roller 5 includes: a bidirectional screw 51, which is vertically rotatably mounted on the circumferential side wall of the positioning roller 45. A limit rod 52 is arranged parallel to one side of the bidirectional screw 51. Two rollers 53 are slidably mounted on the limit rod 52. The rollers 53 are slidably sleeved with the bidirectional screw 51 through threaded engagement. An extending ring 54 is rotatably sleeved on the outside of the rollers 53. The bidirectional screw can drive the two rollers to adjust their displacement synchronously under rotation.

[0027] In this embodiment, the contact surface between the positioning roller 45 and the banner is an arc-shaped cross section. The roller 53 of the extension roller 5 that is in contact with the banner can slide from the center to both sides and adjust and reset after detaching from the banner. That is to say, during the banner stretching and suspension, the adjusting bracket provides the suspension stretching force to the banner. At this time, the positioning roller can continuously rotate so that each extension roller on the positioning roller continuously contacts and abuts against the banner. At this time, the electric telescopic rod in the retracted state gradually extends, and the rollers on the contacting extension rollers extend the banner from the center to both sides, thereby avoiding excessive stretching of the banner while ensuring that the banner is suspended horizontally.

[0028] Specifically, during banner hanging, the four corners of the banner are clamped and positioned by connecting components, and then extended by telescopic adjustment rods. At this time, the positioning rollers in the extension mechanism can abut against the banner through the extension rollers while rotating, and the electric telescopic rods drive each connecting frame to slide to both sides while gradually extending and retracting, while the rollers on the extension rollers slide from the center to both sides, thus extending the banner. In advertising displays, the extension mechanism can be moved to the edge position for static display, and can also provide a continuous undulating effect on the banner through the continuous rotation of the rotating disk during sliding, which has a strong display effect.

[0029] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
