Description

Technical Field

[0001] This application relates to the field of metal frames for light boxes, and more particularly to a light cloth locking mechanism for advertising light boxes. Background Technology

[0002] Advertising light boxes are facilities installed indoors and outdoors to display and promote specific content. By installing lights inside the advertising light box and installing translucent light cloth on the outside of the lights, the light cloth is made more attractive when the lights are lit, thus achieving the desired advertising effect.

[0003] Existing advertising light boxes consist of a base frame, a border, lighting fixtures, and a light cover. The base frame is a metal plate structure, vertically fixed to the wall. The lighting fixtures are fixed to the base frame. The border is located along the edge of the base frame and is used to secure the light cover. The edges of the light cover are fixed to the border to keep the light cover taut, ensuring the content on the light cover is fully displayed for optimal advertising effect. The light cover can be secured inside the light box using bolts or magnets.

[0004] The aforementioned technical solutions have the following drawbacks: In outdoor environments, the light cloth is easily subjected to wind pressure, causing it to loosen or come out of the light box. When the light cloth is fixed inside the light box with bolts, it is difficult to replace the light cloth. Utility Model Content

[0005] In order to ensure that the light cloth can be securely installed inside the light box and is easy to replace, this application provides a light cloth locking mechanism for advertising light boxes.

[0006] The technical solution for the light box fabric locking mechanism provided in this application is as follows:

[0007] A light box light cloth locking mechanism includes a base frame, a claw, a connecting component, and a movable frame. The base frame is fixed to a wall. One end of the connecting component is fixed to the base frame, and the other end is connected to the claw. The connecting component is used to adjust the distance between the claw and the base frame. The claw is used to engage with the light cloth. The movable frame is rotatably connected to the base frame and is used to cover the claw and the connecting component. An arc-shaped cylinder is provided on the claw. The cross-section of the arc-shaped cylinder is an arc. The claw is used to slide along a straight line parallel to the base frame.

[0008] By adopting the above technical solution, and by setting claws on the bottom frame, users can slide the claws horizontally to make the arc-shaped cylinder slide and lock onto the plastic round rod at the edge of the light cloth, thereby fixing the claws to the light cloth. By setting a connecting component on the bottom frame, and setting claws on the connecting component, users can adjust the distance between the claws and the bottom frame through the connecting component, thereby allowing the claws to drive the edge of the light cloth to move, so that the light cloth can be tensioned, improving the advertising display effect. The connection between the claws and the light cloth is relatively stable. When the light cloth is subjected to wind pressure, it can keep the light cloth and the claws fixed. Users can slide the claws horizontally to connect or disconnect the claws from the light cloth, thereby improving the installation efficiency of the light cloth, so that the light cloth can be firmly installed in the light box and is easy to replace.

[0009] Optionally, the bottom frame is provided with an inclined plate, which is set at an angle to the bottom frame. An abutment plate is provided on the side of the inclined plate away from the bottom frame. The abutment plate is parallel to the bottom frame. A sliding plate is provided on the claw, which abuts against the surface of one side of the inclined plate. The connecting component is used to control the claw to slide along the inclined direction of the inclined plate.

[0010] By adopting the above technical solution, by setting an inclined plate on the bottom frame, the inclined plate is tilted away from the light fixture. When the claw is connected to the light cloth, the connecting component drives the claw to slide along the inclined plate. The claw can pull the light cloth and make the light cloth taut. The abutting plate abuts against one side of the light cloth, so that the light cloth is kept parallel to the bottom frame, resulting in a better display effect of the light cloth.

[0011] Optionally, the connecting assembly includes a square nut, a hook, and a bolt. The square nut is connected to the bottom frame, a locking plate is provided on the claw, the hook engages with the locking plate, and the bolt passes through the hook and is threadedly connected to the square nut. The length direction of the bolt is parallel to the inclination direction of the inclined plate.

[0012] By adopting the above technical solution, hooks and square nuts are set on the bolts, so that the square nuts are connected to the bottom frame and the hooks are engaged with the claws. Users can adjust the distance between the hooks and square nuts by turning the bolts, so that the claws can move closer to or away from the bottom frame along the bolt length direction. The hooks and the clamping plate are detachably connected, so users can install claws of different shapes on the connecting components, so that the claws can clamp light cloths of different sizes and specifications.

[0013] Optionally, a connecting plate is provided on the bottom frame, and a protruding plate is provided on the connecting plate. An installation groove is provided on the square nut, and the locking block is inserted into the installation groove. The length direction of the installation groove is parallel to the length direction of the arc-shaped cylinder.

[0014] By adopting the above technical solution, a connecting plate is set on the bottom frame, and a protruding plate is set on the connecting plate, so that the square nut is engaged with the protruding plate, thereby allowing the square nut to slide horizontally on the bottom frame. This makes it convenient for users to slide the connecting components and the claws to different positions on the light cloth, so that the edge of the light cloth is evenly stressed. Users can remove the connecting components and replace bolts of different lengths, so that light cloths of different sizes can be installed on the bottom frame.

[0015] Optionally, a movable frame is rotatably connected to the bottom frame. The movable frame includes a panel and a bottom plate. The panel and bottom plate are connected and perpendicular to each other. An arc-shaped component is provided at the end of the bottom plate away from the panel. An arc-shaped plate and a cylindrical clip are connected to the bottom frame. There is a gap between the arc-shaped plate and the cylindrical clip. The arc-shaped component is engaged in the gap between the arc-shaped plate and the cylindrical clip.

[0016] By adopting the above technical solution, a movable frame is set on the bottom frame, which can rotate and cover the outside of the claw, reducing the chance of debris getting stuck in the claw and connecting components, improving the aesthetics. When the user rotates the movable frame, the arc-shaped part rotates between the arc-shaped plate and the cylindrical clamp, and the arc-shaped part can move in a straight line between the arc-shaped plate and the cylindrical clamp, thereby improving the flexibility of the movable frame.

[0017] Optionally, a protruding plate is provided at one end of the arc-shaped component away from the base plate, and a locking block is provided on the side surface of the arc-shaped plate near the cylindrical locking component, with the protruding plate abutting against the locking block.

[0018] By adopting the above technical solution, and by setting a locking block on the arc plate, when the movable frame rotates on the bottom frame, the arc-shaped component rotates between the arc plate and the cylindrical locking component. When the convex plate is locked on the locking block, the movable frame is difficult to continue rotating, thereby maintaining a stable connection between the bottom frame and the movable frame.

[0019] Optionally, a spring steel is provided on the bottom frame, with one end of the spring steel connected to the bottom frame and the other end connected to the panel.

[0020] By adopting the above technical solution, spring steel is set on the bottom frame, which is connected to the movable frame and applies elastic force to the movable frame. When the movable frame rotates to the point where the panel is parallel to the bottom frame, the movable frame remains stationary. When the movable frame rotates to the point where the claws and connecting components are exposed, the movable frame also remains stationary, which makes it convenient for users to replace the light cloth and tighten the bolts.

[0021] Optionally, the claw is provided with a push rod, the length direction of which is parallel to the length direction of the arc-shaped cylinder.

[0022] By adopting the above technical solution, and by setting a push rod on the claw, the user can push and pull the push rod to make the claw slide in the horizontal direction, thereby making it easier to connect the arc-shaped cylinder and the light cloth.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting claws on the bottom frame, users can slide the claws horizontally to make the arc-shaped cylinder slide and lock onto the plastic round rod at the edge of the light cloth, thus fixing the claws to the light cloth. By setting a connecting component on the bottom frame and setting claws on the connecting component, users can adjust the distance between the claws and the bottom frame through the connecting component, so that the claws can drive the edge of the light cloth to move, so that the light cloth can be tensioned, improving the advertising display effect. The connection between the claws and the light cloth is relatively stable. When the light cloth is subjected to wind pressure, it can keep the light cloth and the claws fixed. Users can slide the claws horizontally to connect or disconnect the claws from the light cloth, thereby improving the installation efficiency of the light cloth, so that the light cloth can be firmly installed in the light box and is easy to replace.

[0025] 2. By setting hooks and square nuts on the bolts, the square nuts are connected to the bottom frame, and the hooks engage with the claws. Users can adjust the distance between the hooks and square nuts by turning the bolts, so that the claws can move closer to or away from the bottom frame along the length of the bolts. The hooks and the clamping plates are detachably connected, and users can install claws of different shapes on the connecting components, so that the claws can clamp light cloths of different sizes and specifications.

[0026] 3. By setting a movable frame on the bottom frame, the movable frame can rotate and cover the outside of the claw, reducing the chance of debris getting stuck in the claw and connecting components, improving the aesthetics. When the user rotates the movable frame, the arc-shaped part rotates between the arc-shaped plate and the cylindrical clamp, and the arc-shaped part can move in a straight line between the arc-shaped plate and the cylindrical clamp, thereby improving the flexibility of the movable frame.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses a light cloth locking mechanism for advertising light boxes, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a base frame 1, claws 2, connecting components 3, and a movable frame 4. The base frame 1 is a metal plate structure, and the light fixture is mounted on the base frame 1. Claws 2 are slidably connected to the bottom of the base frame 1 and are used for detachable connection with the light cloth. The connecting components 3 are connected between the claws 2 and the base frame 1 and are used to adjust the position of the claws 2 on the base frame 1. The movable frame 4 is rotatably connected to the bottom of the base frame 1 and can rotate to cover the claws 2 and connecting components 3. When installing the light cloth, the user rotates the movable frame 4 to expose the claws 2 and connecting components 3. By mounting the edge of the light cloth onto the claws 2, the upper and lower edges of the light cloth can be fixed to the upper and lower sides of the base frame 1, respectively. The connecting components 3 allow the claws 2 to slide, thereby clamping the light cloth and keeping it taut, thus completing the installation of the light cloth.

[0036] Reference Figure 4 The claw 2 includes an arc-shaped cylinder 21. The cross-section of the arc-shaped cylinder 21 is an arc. Plastic round rods are fixed to the upper and lower edges of the light cloth. The arc-shaped cylinder 21 can slide and be locked on the plastic round rods. The user can slide the claw 2 through the connecting component 3, thereby putting force on the upper and lower ends of the light cloth, keeping the light cloth taut, and achieving a better display effect.

[0037] Reference Figure 2 A ramp 11 is provided on the base frame 1, and the ramp 11 is inclined relative to the base frame 1, with the inclined direction away from the light cloth. A slide plate 22 is provided on the claw 2, and the slide plate 22 abuts against the lower side of the ramp 11. The connecting component 3 is used to control the claw 2 to slide along the inclined direction of the ramp 11. An abutment plate 111 is provided on the end of the ramp 11 away from the base frame 1, and the abutment plate 111 is parallel to the base frame 1. When the claw 2 moves the edge of the light cloth to slide, the abutment plate 111 can abut against the surface of the light cloth, thereby tautning the surface of the light cloth.

[0038] Reference Figure 1and Figure 2 A connecting plate 12 is provided on the bottom frame 1, located below the inclined plate 11 and parallel to it. A protruding plate 121 is provided at the end of the connecting plate 12 away from the bottom frame 1. The connecting assembly 3 is detachably connected to the protruding plate 121. A locking plate 23 is provided on the claw 2, and the locking plate 23 is detachably connected to the connecting assembly 3. The connecting assembly 3 controls the gap between the protruding plate 121 and the locking plate 23, allowing the claw 2 to slide along the inclined plate 11, thus facilitating the installation and tensioning of the light cloth by the user.

[0039] Reference Figure 5 The connecting component 3 includes a square nut 31, a hook 32, and a bolt 33. The bolt 33 passes through the hook 32 and is threadedly connected to the square nut 31. The length direction of the bolt 33 is parallel to the inclination direction of the inclined plate 11. The square nut 31 has a mounting groove 311, and the protruding plate 121 is engaged in the mounting groove 311. The hook 32 is engaged with the clamping plate 23. When the user tightens the bolt 33, the bolt 33 can slide relative to the square nut 31, thereby allowing the claw 2 to slide on the inclined plate 11, achieving the effect of tightening or loosening the lamp cloth.

[0040] Reference Figure 1 When the user installs the light cloth, first slide the claw 2 horizontally. When the claw 2 slides, the clamping plate 23 always stays engaged with the hook 32. When the arc-shaped cylinder 21 is connected to the edge of the light cloth, the user can turn the bolt 33 to make the claw 2 slide towards the bottom frame 1. At this time, the abutment plate 111 abuts against the light cloth, making the light cloth taut.

[0041] Reference Figure 2 An arc-shaped plate 13 is provided on the bottom frame 1, located on the side of the connecting plate 12 away from the inclined plate 11. A cylindrical clamp 14 is provided on the side of the arc-shaped plate 13 away from the connecting plate 12, and there is a gap between the cylindrical clamp 14 and the arc-shaped plate 13. The movable frame 4 includes a panel 41 and a bottom plate 42, which are connected and perpendicular to each other. An arc-shaped component 421 is provided on the end of the bottom plate 42 away from the panel 41, and the arc-shaped component 421 is engaged in the gap between the cylindrical clamp 14 and the arc-shaped plate 13. When the movable frame 4 rotates, the arc-shaped component 421 rotates in contact with the cylindrical clamp 14. The arc-shaped component 421 can move in a straight line between the cylindrical clamp 14 and the arc-shaped plate 13, thereby improving the flexibility of the movable frame 4 and allowing the panel 41 to rotate to a state parallel to the bottom frame 1 and cover the claw 2 and the connecting component 3, improving the aesthetics and reducing the probability of debris getting stuck in the connecting component 3.

[0042] Reference Figure 6A protruding plate 422 is provided on the end of the arc-shaped part 421 away from the base plate 42. A locking block 131 is provided on the side surface of the arc plate 13 near the cylindrical locking part 14. When the movable frame 4 rotates to a certain angle relative to the base frame 1, the protruding plate 422 can be locked on the locking block 131, making it difficult for the movable frame 4 to continue to rotate. The protruding plate 422 can lock the movable frame 4 on the base frame 1, reducing the probability of the movable frame 4 disengaging from the base frame 1.

[0043] Reference Figure 1 A baffle plate 411 is provided on the end of the panel 41 away from the bottom plate 42. The baffle plate 411 is perpendicular to the panel 41. When the movable frame 4 is covered outside the claw 2, the baffle plate 411 is set horizontally, thereby reducing the probability of debris falling into the movable frame 4.

[0044] Reference Figure 1 A spring steel 43 is provided on the movable frame 4. The spring steel 43 is elastic. One end of the spring steel 43 is fixed to the arc plate 13, and the other end is fixed to the panel 41. When the movable frame 4 rotates to the point where the panel 41 is parallel to the bottom frame 1, the spring steel 43 applies a spring force to the movable frame 4, making the movable frame 4 stationary relative to the bottom frame 1. The spring steel 43 can apply a tensile force to the movable frame 4, causing the baffle plate 411 to abut against the abutting plate 111. In other embodiments, the spring steel 43 applies a pushing force to the movable frame 4, causing the arc member 421 to abut against the cylindrical clip 14, thereby keeping the panel 41 fixed. When the user rotates the movable frame 4, the spring steel 43 deforms, allowing the movable frame 4 to rotate. When the movable frame 4 rotates to the point where the convex plate 422 abuts against the clip 131, the spring steel 43 rebounds and applies a spring force to the movable frame 4, keeping the movable frame 4 fixed. At this time, the user can tighten the bolt 33 and replace the lamp cloth.

[0045] In other embodiments, refer to Figure 4 The claw 2 is equipped with a push rod 24, the length direction of which is parallel to the thickness direction of the claw 2. When the claw 2 is connected to the connecting assembly 3, the length direction of the push rod 24 is horizontal. By pushing the push rod 24, the user can make the claw 2 slide horizontally, thereby allowing the arc-shaped cylinder 21 to be locked onto the plastic round rod at the edge of the light cloth, facilitating the loading and unloading of the light cloth.

[0046] The implementation principle of this application embodiment is as follows: by setting the connecting component 3 on the bottom frame 1, the claw 2 is installed on the connecting component 3. The claw 2 can slide in the horizontal direction, so that the arc-shaped cylinder 21 is connected to the lamp cloth. When the user tightens the bolt 33, the square nut 31 can slide relative to the hook 32, thereby tightening the lamp cloth. By rotating the connecting movable frame 4 on the bottom frame 1, the movable frame 4 can cover the outside of the claw 2 and the connecting component 3, thereby reducing the probability of debris falling into the claw 2 and the connecting component 3.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
