Description

Technical Field

[0001] This utility model relates to the field of advertising light box technology, specifically a light cloth tensioning device. Background Technology

[0002] Fabric light boxes are outdoor advertising light boxes made of aluminum profile frames and knife-coated fabric, primarily used in large outdoor venues such as shopping malls, subways, and airports. Their core features include high strength, oxidation resistance, acid and alkali resistance, and cold resistance, making them suitable for long-term outdoor display.

[0003] The fabric lightbox is mainly composed of a frame, round steel bars, light cloth, and nylon cable ties. The round steel bars are fixedly installed inside the frame. When installing the light cloth, the nylon cable ties first pass through the round steel bars, then through the steel rings at the edge of the light cloth, and then the nylon cable ties are tightened to make the light cloth and other components taut and flat within the frame.

[0004] However, when using nylon cable ties to secure the light box, it is easy to find that the ties are not tight enough, which can cause the light box to loosen and affect the display effect. At the same time, since light boxes are mostly located outdoors, the nylon cable ties will age faster, which can also cause the light box to loosen and affect the advertising effect.

[0005] In view of this, we propose a lamp cloth tensioning device. Utility Model Content

[0006] The purpose of this utility model is to provide a lamp cloth tensioning device to solve the problem mentioned in the background art of loose lamp cloth fixing affecting the display effect.

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

[0008] A light curtain tensioning device includes a profile frame, adjusting angle brackets, tensioning bolts, round steel bars, light curtain hooks, and a light curtain body. The profile frame consists of a lower profile frame, an upper profile frame, and a profile flap. The upper profile frame is fixedly mounted on the lower profile frame, and the profile flap is rotatably mounted on the upper profile frame. The lower and upper profile frames are fixedly connected by a snap-fit ​​mechanism, facilitating the transportation and installation of the profile frame. The profile flap is rotatably connected to the upper profile frame, allowing the flap to open or close the upper profile frame. Adjusting angle brackets are linearly arrayed within the upper profile frame, with multiple adjusting angle brackets slidably mounted within the frame. Tensioning bolts are slidably mounted on the adjusting angle brackets, and round steel bars are slidably mounted within each bracket. The tensioning bolts are located at... Above the round steel bar, the bottom of the tensioning bolt contacts the surface of the round steel bar, and the round steel bar is slidably installed within the adjusting bracket. A lamp cloth hook is slidably installed on the round steel bar, and a lamp cloth body is installed on the lamp cloth hook. The tensioning bolt drives the round steel bar to slide vertically, thereby causing the lamp cloth hook to move synchronously to adjust the tension of the lamp cloth body. The lamp cloth hook can slide and rotate on the round steel bar, thereby adjusting its own position. The sliding of the tensioning bolt on the adjusting bracket pushes the round steel bar to move synchronously, thus fixing the round steel bar. When the round steel bar slides, it drives the lamp cloth hook that has been fixed on it to move synchronously. The lamp cloth hook pulls the lamp cloth body, completing the tensioning and fixing of the lamp cloth body, keeping the lamp cloth body flat.

[0009] Preferably, the adjusting angle bracket is divided into a fixed section and an adjusting section. The adjusting angle bracket is slidably installed in the upper frame of the profile through the fixed section. The adjusting section is an inverted L-shaped structure. A guide groove is provided on the vertical section of the inverted L-shaped structure. A round steel is slidably installed in the guide groove. A threaded groove is provided on the horizontal section of the inverted L-shaped structure. A tensioning bolt is slidably installed on the adjusting angle bracket through the threaded groove. The round steel is slidably installed in the guide groove of the adjusting angle bracket. The guide groove restricts its sliding trajectory, thereby ensuring its stable movement. The tensioning bolt is slidably installed on the adjusting angle bracket through a threaded connection. By rotating the tensioning bolt, it slides vertically on the adjusting angle bracket through the thread. When the tensioning bolt slides vertically downward, it pushes the round steel to move downward synchronously through its bottom end.

[0010] Preferably, the guide groove is 25mm long, which is about 10mm longer than the adjustment distance of traditional cable ties. This makes it suitable for all indoor and outdoor light boxes of all sizes, thus enhancing the applicability of the tensioning device.

[0011] Preferably, the upper frame of the profile has a slot, and the fixed section of the adjusting angle bracket has an insert. The fixed section and the upper frame of the profile are slidably connected through the cooperation of the insert and the slot. The insert has a convex shape, and the slot is shaped to cooperate with the insert. The convex shape of the insert and the slot enhances the contact area between them, thereby enhancing the stability of the adjusting angle bracket installed on the upper frame of the profile.

[0012] Preferably, the lamp cloth hook is connected to the round steel through an interference fit. The interference fit enhances the friction between the lamp cloth hook and the round steel, ensuring the stability of the lamp cloth hook in the axial installation of the round steel while maintaining the stability of the lamp cloth hook's deflection. This prevents the lamp cloth hook from being pulled by the reaction force of the lamp cloth body when the lamp cloth body is tensioned, thus affecting the installation effect.

[0013] Preferably, the lamp cloth body is provided with a hanging hole that cooperates with the lamp cloth hook. When installing the lamp cloth body, the lamp cloth body and the lamp cloth hook are fixedly installed by inserting the hanging hole into the lamp cloth hook. Then, by rotating the tension bolt, the tension bolt slides vertically downward, thereby pushing the round steel to move synchronously. The round steel drives the lamp cloth hook to move synchronously. The lamp cloth hook pulls the lamp cloth body to tension through the hanging hole, thus completing the fixation of the lamp cloth body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this utility model improves the convenience of installing the lamp cloth body and the installation efficiency through the tensioning device, and realizes the adjustment of the tension force of the lamp cloth body. At the same time, the extension design of the guide groove improves the applicability of the tensioning device, making the tensioning device adaptable to the installation of different lamp cloth bodies.

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.

[0029] like Figures 1 to 6 As shown, a lamp cloth tensioning device includes a profile frame 1, adjusting brackets 2, tensioning bolts 3, round steel bars 4, and lamp cloth hooks 5. The profile frame 1 consists of a lower profile frame 11, an upper profile frame 12, and a profile flip cover 13. The upper profile frame 12 is fixedly installed on the lower profile frame 11, and the profile flip cover 13 is rotatably installed on the upper profile frame 12. Adjusting brackets 2 are linearly arrayed inside the upper profile frame 12. Tensioning bolts 3 are slidably installed on the adjusting brackets 2, and round steel bars 4 are slidably installed inside the adjusting brackets 2. The tensioning bolts 3 are located above the round steel bars 4. Lamp cloth hooks 5 are slidably installed on the round steel bars 4, and lamp cloth is installed on the lamp cloth hooks 5. The tensioning bolts 3 drive the round steel bars 4 to slide vertically, thereby causing the lamp cloth hooks 5 to move synchronously to adjust the tension of the lamp cloth.

[0030] Specifically, the profile frame 1 consists of a lower profile frame 11, an upper profile frame 12, and a profile flip cover 13. The upper profile frame 12 is fixedly installed on the lower profile frame 11, and the profile flip cover 13 is rotatably installed on the upper profile frame 12. The lower profile frame 11 and the upper profile frame 12 are fixedly connected by a snap-fit, which facilitates the transportation and installation of the profile frame 1. The profile flip cover 13 is rotatably connected to the upper profile frame 12, which allows the upper profile frame 12 to be opened or closed by rotating the profile flip cover 13. Adjustable angle brackets 2 are linearly arrayed inside the upper profile frame 12. Multiple adjustable angle brackets 2 are slidably installed inside the upper profile frame 12. Tensioning bolts 3 are slidably installed on the adjusting angle brackets 2, and round steel 4 is slidably installed inside the adjusting angle brackets 2. The tensioning bolts 3 are located above the round steel 4, and the bottom of the tensioning bolts 3 contacts the surface of the round steel 4. The round steel 4 is slidably installed inside the adjusting angle brackets 2. A light cloth hook 5 is slidably mounted on steel 4. A light cloth is mounted on the light cloth hook 5. The tension bolt 3 drives the round steel 4 to slide vertically, thereby causing the light cloth hook 5 to move synchronously to adjust the tension of the light cloth. The light cloth hook 5 can slide and rotate on the round steel 4 to adjust its own position. The tension bolt 3 slides vertically downward, thereby pushing the round steel 4 to move synchronously and fix the round steel 4. When the round steel 4 slides, it drives the fixed light cloth hook 5 to move synchronously. The light cloth hook 5 pulls the light cloth to complete the tensioning and fixing of the light cloth, keeping the light cloth flat. When the tension of the light cloth is large, the tension bolt 3 slides vertically upward to reduce the squeezing force on the round steel 4, thereby causing the light cloth to pull the round steel 4 vertically upward through the light cloth hook 5, releasing the tension.

[0031] In this embodiment, the adjusting angle bracket 2 is divided into a fixed section 21 and an adjusting section 22. The adjusting angle bracket 2 is slidably installed in the upper frame 12 of the profile through the fixed section 21. The adjusting section 22 is an inverted L-shaped structure 221. A guide groove 2211 is provided on the vertical section of the inverted L-shaped structure 221. A round steel 4 is slidably installed in the guide groove 2211. A screw groove 233 is provided on the horizontal section of the inverted L-shaped structure 221. A tensioning bolt 3 is slidably installed on the adjusting angle bracket 2 through the screw groove 233.

[0032] Specifically, the round steel 4 is slidably installed in the guide groove 2211 of the adjusting angle bracket 2. The guide groove 2211 restricts its sliding trajectory, thereby ensuring its stable movement. The tensioning bolt 3 is slidably installed on the adjusting angle bracket 2 through a threaded connection. By rotating the tensioning bolt 3, it slides vertically on the adjusting angle bracket 2 through the thread. When the tensioning bolt 3 slides vertically downward, it pushes the round steel 4 to move downward synchronously through its bottom end. The round steel 4 drives the lamp cloth hook 5 to move synchronously to achieve tensioning of the lamp cloth.

[0033] In this embodiment, the guide groove 2211 is 25mm;

[0034] Specifically, the guide groove 2211 is designed to be about 25mm long, which is about 10mm longer than the adjustment distance of traditional cable ties. This makes it suitable for all indoor and outdoor light boxes of all sizes, thus enhancing the applicability of the tensioning device.

[0035] In this embodiment, a slot 121 is provided in the upper frame 12 of the profile, and a plug 211 is provided on the fixed section 21 of the adjusting bracket 2;

[0036] Specifically, the fixed section 21 and the upper frame of the profile 12 are slidably connected through the cooperation of the insert 211 and the slot 121, so that the adjustment bracket 2 can slide freely within the upper frame of the profile 12 and thus adjust its position. The insert 211 has a convex shape, and the slot 121 is shaped to cooperate with the insert 211. The convex shape of the insert 211 and the slot 121 enhances the contact area between them, thereby enhancing the stability of the adjustment bracket 2 installed on the upper frame of the profile 12.

[0037] In this embodiment, the lamp cloth hook 5 is connected to the round steel 4 by an interference fit;

[0038] Specifically, the lamp cloth hook 5 enhances the friction between itself and the round steel 4 through an interference fit, ensuring the stability of the lamp cloth hook 5 in the axial installation of the round steel 4, while maintaining the stability of the lamp cloth hook 5 in deflection, and preventing the lamp cloth hook 5 from being pulled by the reaction force of the lamp cloth when the lamp cloth is tensioned, thus affecting the installation effect.

[0039] Preferably, the lamp cloth hook 5 can move arbitrarily along the axis of the round steel 4 and has a certain angle of sway to facilitate the correspondence between the lamp cloth hook 5 and the hanging hole 61, and facilitate the connection between the lamp cloth hook 5 and the hanging hole 61.
