Description

Technical Field

[0001] This utility model relates to the field of advertising signage technology, and more specifically, to a column lightbox with a quick-opening and closing lock. Background Technology

[0002] Column-mounted light boxes are a common type of outdoor or indoor advertising display equipment, typically installed on columns or the exterior facade of buildings. By wrapping the light box structure around the column, it creates a multi-faceted advertising display area, attracting the attention of pedestrians and vehicles from multiple angles. One example of a light box support column disclosed in the prior art includes a hollow column body made of aluminum alloy profiles. The column body has a rectangular frame structure in cross-section, with vertical grooves on three outer sides. The bottom of the column body has a detachable base, which is fixed to the ground by pre-embedded parts.

[0003] In existing technology, the light source panel of some advertising light boxes is slidably mounted on the frame, and the light source panel is locked to the outer surface of the frame by multiple locking components. When changing the canvas on the light source panel, the worker opens the multiple locking components and then pulls the light source panel to slide it out. After changing the canvas, the worker pushes the light source panel to slide it tightly against the outer side of the frame, and finally closes all the locking components, thereby locking the light source panel to the frame.

[0004] However, opening or closing the light source panel of the advertising light box requires multiple switch locks, resulting in low operational efficiency. Furthermore, for the lock components located at higher positions, workers need to climb to operate them, posing certain safety risks. Utility Model Content

[0005] In view of the problems in the prior art where the switching and locking of the light source panel requires multiple points of operation, resulting in low work efficiency and high safety risks due to the need for climbing, the present invention provides a column-mounted light box that can be quickly switched on and off, which can improve the efficiency of switching and locking, and eliminate the need for high-altitude work, thereby reducing the safety risks of the operation.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A column-mounted light box with a quick-opening and closing lock includes a frame, a light source panel, and a locking assembly. The light source panel is slidably mounted on the frame, and the locking assembly locks the light source panel securely to the outside of the frame. The locking assembly includes a lifting drive assembly and a lifting rod. The lifting drive assembly is mounted on the frame, and its power output end is connected to the lifting rod. The lifting rod is connected to a first connecting structure, and the light source panel has a second connecting structure. The second connecting structure engages with the first connecting structure when the lifting rod rises or falls. The connection between the first and second connecting structures can be a snap-fit, socket, or other similar method.

[0008] In the above technical solution, the first connecting structure is connected to the second connecting structure, thereby locking the light source panel onto the frame. When it is necessary to replace the canvas on the light source panel, the lifting drive assembly is used to drive the lifting rod to rise or fall, causing the first connecting structure to disengage from the second connecting structure, thus completing the unlocking action; then the light source panel is pulled out to replace the canvas on the light source panel; after the canvas is replaced, the light source panel is pushed back to abut against the outside of the frame, and then the lifting drive assembly is used to drive the lifting rod to fall or rise, causing the first connecting structure to connect with the second connecting structure, thereby locking the light source panel back onto the outside of the frame, thus completing the locking action.

[0009] Preferably, the first connecting structure includes a wedge hook connected to the lifting rod, the wedge hook having a driving ramp, the top of the driving ramp being horizontally further from the frame than its bottom; the second connecting structure includes a connecting ring assembly connected to the light source panel, the connecting ring assembly having a through cavity or the connecting ring assembly and the light source panel forming a through cavity, the wedge hook at least partially passing through the through cavity and the connecting ring assembly abutting against the driving ramp. When the light source panel is connected to the frame, the wedge hook hooks onto the connecting ring assembly. The wedge hook hooks onto the connecting ring assembly, thereby locking the light source panel to the outside of the frame. When unlocking, the lifting drive assembly drives the lifting rod to descend until the wedge hook is completely disengaged from the connecting ring assembly, thus completing the unlocking action; when locking, the lifting drive assembly drives the lifting rod to rise; when the wedge hook rises to pass through the through cavity and the connecting ring assembly contacts the driving ramp, as the wedge hook continues to rise, the driving ramp pushes the connecting ring assembly closer to the lifting rod, thereby causing the light source panel to continue to move closer to the frame until it is pressed tightly against the outside of the frame, thus completing the locking action.

[0010] The lifting drive assembly can be manually driven or automatically driven. If it is automatically driven, the lifting drive assembly can be one of the following: a motor screw drive assembly, a gear and rack drive assembly, an electric actuator drive assembly, a synchronous belt drive assembly, etc.

[0011] Preferably, the lifting rod is slidably connected to the frame in a vertical direction; the lifting drive assembly includes a support, a push rod, and a transmission component, the support is disposed at the bottom of the frame, and at least part of the push rod is threadedly or slidably connected to the support; the transmission component has a first connecting part, a second connecting part, and a third connecting part that are not on the same straight line, one end of the push rod is rotatably connected to the transmission component through the first connecting part, and the end of the push rod connected to the first connecting part is higher than its other end; the transmission component is rotatably connected to the support through the second connecting part, and the bottom end of the lifting rod is rotatably connected to the transmission component through the third connecting part; the rotation axes of the first connecting part, the second connecting part, and the third connecting part are all horizontal axes and are parallel to each other; the lifting rod rises and falls when the push rod pushes and pulls the transmission component. When the push rod is manually pushed inward or pulled outward, the transmission component rotates relative to the push rod around the rotation axis at the first connection point, simultaneously rotating relative to the support around the rotation axis at the second connection point, and also rotating relative to the lifting rod around the rotation axis at the third connection point. During the rotation of the transmission component, the height of the third connection point changes, thereby raising or lowering the lifting rod. Manual operation avoids accidental raising or lowering due to power failures or control system problems, and prevents the frame from accidentally detaching, thus enhancing safety. Furthermore, this lifting drive assembly has a simpler structure and lower manufacturing and maintenance costs compared to electrically driven assemblies.

[0012] Preferably, the push rod is threadedly connected to the support, and a hand crank is detachably connected to the end of the push rod away from the support. The push rod is moved by cranking the hand crank. The threaded connection has a self-locking characteristic, maintaining the position of the lifting rod when the hand crank is stopped, eliminating the need for an additional locking device. After the locking assembly is closed, the hand crank can be removed to prevent the push rod from being maliciously driven.

[0013] Preferably, the lifting rod is located between the light source panel and the frame, and the hand crank is located on the outer side of the light source panel. Hiding the lifting rod on the inner side of the light source panel makes the exterior of the panel neater and more aesthetically pleasing, and also avoids the effects of external environmental factors such as dust, moisture, or impacts, thus helping to extend the lifespan of the lifting drive assembly.

[0014] Preferably, the inner side of the frame is provided with a guide structure, and the inner side of the light source panel is provided with a sliding rod, the sliding rod being slidably connected to the guide structure in the horizontal direction.

[0015] Preferably, the guide structure includes a support rail and rollers disposed on the inner side of the frame. The rotation axis of the rollers is a horizontal line and perpendicular to the length axis of the sliding rod. The bottom and top sides of the sliding rod abut against the support rail and the rollers, respectively. When installing the light source panel, the sliding rod is first placed on the support rail, and then the light source panel is pushed inward to make the support rail slide inward along the space between the support rail and the rollers until the connecting ring assembly is near the lifting rod. Then, the lifting rod is driven to rise so that the wedge hook engages the connecting ring assembly. The rollers can reduce friction on the sliding rod, thereby reducing the sliding resistance of the sliding rod and reducing the noise generated during the sliding process.

[0016] Preferably, the guide structure has at least two sets, with at least two sets of the guide structure located on two opposite inner sides of the frame, and at least two sliding rods that correspond one-to-one with the guide structures. This allows the light source panel to be subjected to more even force and to move more smoothly.

[0017] Preferably, the connecting ring assembly includes a first support member, a second support member, a third support member, and a rotating shaft. The first support member is connected to the inner side of the light source panel, the second and third support members are respectively connected to the first support member, and the two ends of the rotating shaft are rotatably connected to the second and third support members, respectively. The first, second, and third support members and the rotating shaft form the through cavity, and the outer circumferential surface of the rotating shaft abuts against the driving inclined surface. During the lifting and lowering of the wedge hook, the rotating shaft rotates due to friction from the driving inclined surface. The rotating shaft can reduce friction on the driving inclined surface, which helps to extend the service life of the connecting ring assembly and reduce the lifting and lowering driving resistance of the lifting rod.

[0018] Preferably, the lifting drive assembly has at least two sets, and the lifting rod has at least two members, each connected to one of the lifting drive assemblies in a one-to-one correspondence; that is, one lifting drive assembly corresponds to one lifting rod. The at least two lifting rods are located on either side of the vertical center line of the light source panel. Multiple wedge hooks are provided, with at least some distributed linearly along the axial direction of the lifting rods. The light source panel has multiple connecting ring assemblies, each corresponding to one of the wedge hooks in a one-to-one correspondence; that is, one wedge hook corresponds to one connecting ring assembly. Providing at least two lifting rods and multiple wedge hooks ensures more even force distribution on the light source panel, preventing tilting, shaking, or detachment, thus allowing the canvas on the light source panel to better display advertising content.

[0019] Preferably, the light source panel has at least two light sources, each located on a different side of the frame and detachably connected to the frame. Adjacent light source panels form a 90° angle. At least one side of each light source panel has a beveled joint, and the beveled joints of adjacent light source panels fit together. The beveled joint allows adjacent light source panels to fit more tightly, reducing gaps at the joints and thus increasing the overall effective light-emitting area of ​​the light source panel.

[0020] It should be noted that the descriptions of the positional and connection relationships of the structure in this manual are all made when the light source panel is connected to the frame.

[0021] The beneficial effects of this utility model are as follows: The lock assembly includes a lifting drive assembly, a lifting rod, and a first connecting structure. At the same time, a second connecting structure that can cooperate with the first connecting structure is provided on the light source panel. The locking and unlocking of the light source panel does not require multi-point operation or climbing operation. The locking and unlocking can be completed by driving the lifting rod to lift and lower through the lifting drive assembly, which can significantly improve the efficiency and security of locking and unlocking.

[0035] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0036] Example 1

[0037] This embodiment is a first embodiment of a pillar-mounted light box with a quick-opening and closing lock, combined with... Figures 1 to 7 As shown, it includes a frame 1, a light source panel 2, and a locking assembly. The frame 1 is a square frame structure. The light source panel 2 is used to mount the canvas and is slidably mounted on the frame 1. The locking assembly locks the light source panel 2 to the outside of the frame 1.

[0038] Specifically, the lock assembly includes a lifting drive assembly 3, a lifting rod 4, and a wedge hook 5 connected to the lifting rod 4; the lifting drive assembly 3 is located at the bottom of the frame 1 and its power output end is connected to the lifting rod 4, the lifting rod 4 is located between the light source panel 2 and the frame 1; the lifting rod 4 is connected to a first connecting structure, and the light source panel 2 is provided with a second connecting structure, the second connecting structure is engaged with the first connecting structure when the lifting rod 4 rises or falls.

[0039] Specifically, the first connecting structure includes a wedge hook 5 connected to the lifting rod 4. The wedge hook 5 has a driving inclined surface 501, and the horizontal distance between the top end of the driving inclined surface 501 and the frame 1 is greater than that between its bottom end. Specifically, a guide plate 9 is connected to the frame 1, and a limiting through hole 901 is provided on the guide plate 9. The lifting rod 4 passes through the limiting through hole 901 and slides vertically connected to the limiting through hole 901. The wedge hook 5 is set on the guide plate 9, and the lifting rod 4 is connected to the wedge hook 5 through the guide plate 9. Further, the second connecting structure includes a connecting ring assembly 6 set on the inner side of the light source panel 2. The connecting ring assembly 6 has a through cavity, and the top end of the wedge hook 5 passes through the through cavity and the connecting ring assembly 6 abuts against the driving inclined surface 501.

[0040] It should be noted that the descriptions of the positional and connection relationships of the structures in this embodiment are all made when the light source panel 2 is connected to the frame 1.

[0041] The working principle or workflow of this embodiment is as follows: The wedge hook 5 hooks onto the connecting ring assembly 6, thereby locking the light source panel 2 to the outside of the frame 1. When it is necessary to replace the canvas on the light source panel 2, the lifting drive assembly 3 can be used to drive the lifting rod 4 to descend until the wedge hook 5 is completely disengaged from the connecting ring assembly 6, thus completing the unlocking action; then the light source panel 2 is pulled out to replace the canvas on the light source panel 2; after the canvas is replaced, the light source panel 2 is pushed back to abut against the outside of the frame 1, and then the lifting drive assembly 3 is used to drive the lifting rod 4 to rise; when the wedge hook 5 rises to pass through the cavity and the connecting ring assembly 6 contacts the driving inclined surface 501, as the wedge hook 5 continues to rise, the driving inclined surface 501 will push the connecting ring assembly 6 closer to the lifting rod 4, thereby causing the light source panel 2 to continue to move closer to the frame 1 until it is pressed tightly against the outside of the frame 1, thus completing the locking action.

[0042] The beneficial effects of this embodiment are as follows: The lock assembly includes a lifting drive assembly, a lifting rod, and a wedge hook. The locking and unlocking of the light source panel does not require multi-point operation or climbing operation. The locking and unlocking can be completed by driving the lifting rod to lift and lower through the lifting drive assembly, which can significantly improve the efficiency and security of locking and unlocking.

[0043] Example 2

[0044] This embodiment is a second embodiment of a pillar-mounted light box with a quick-opening and closing lock. This embodiment is similar to embodiment 1, except that it combines... Figures 1 to 8 As shown, the lifting drive assembly 3 includes a support 301, a push rod 302, and a transmission component 303. The support 301 is located at the bottom of the frame 1. The push rod 302 is inclined and threadedly connected to the support 301. One end of the push rod 302 has an extension 3021. The transmission component 303 has a first connecting part 3031, a second connecting part 3032, and a third connecting part 3033 that are not on the same straight line. The extension 3021 on the push rod 302 is connected to the transmission component 303 through the first connecting part 3031. The transmission component 303 is rotatably connected, and the end of the extension 3021 on the push rod 301 is higher than the other end of the push rod 301; the transmission component 303 is rotatably connected to the support 301 through the second connecting part 3032, and the bottom end of the lifting rod 4 is rotatably connected to the transmission component 303 through the third connecting part 3033; the rotation axes of the first connecting part 3031, the second connecting part 3032, and the third connecting part 3033 are all horizontal axes and are parallel to each other; the lifting rod 4 rises and falls when the push rod 302 pushes and pulls the transmission component 303. When the push rod 302 is manually pushed inward or pulled outward, the transmission component 303 rotates relative to the push rod 302 around the rotation axis at the first connecting part 3031, rotates relative to the support 301 around the rotation axis at the second connecting part 3032, and rotates relative to the lifting rod 4 around the rotation axis at the third connecting part 3033; during the rotation of the transmission component 303, the height of the third connecting part 3033 changes, thereby causing the lifting rod 4 to rise and fall. Manual operation avoids accidental lifting or lowering due to power failure or control system problems, and prevents frame 1 from accidentally detaching from frame 1, thus enhancing safety. Furthermore, this lifting drive component 3 has a simpler structure and lower manufacturing and maintenance costs compared to electrically driven components.

[0045] Furthermore, a hand crank 304 is detachably connected to the end of the push rod 302 away from the support 301. The hand crank 304 is located on the outer side of the light source panel 2, meaning it is exposed. The push rod 302 is moved by cranking the hand crank 304. The threaded connection has a self-locking characteristic, which can maintain the position of the lifting rod 4 when the hand crank 304 is stopped, without the need for an additional locking device. After the locking assembly is closed, the hand crank 304 can be removed to prevent the push rod 302 from being maliciously driven.

[0046] Specifically, the push rod 302 has a force-receiving blind hole 3022 at the end away from the support 301, and a force-applying plug 3041 at one end of the hand crank 304. The force-applying plug 3041 is inserted into the force-receiving blind hole 3022, and the outer peripheral side of the force-applying plug 3041 is in contact with the inner wall of the force-receiving blind hole 3022. The cooperation between the hand crank 304 and the push rod 302 is relatively simple, allowing for quick assembly and disassembly of the hand crank 304.

[0047] Furthermore, combined Figure 9 and Figure 10 As shown, a guide structure 8 is provided on the inner side of the frame 1, which is the side of the frame 1 that faces away from the light source panel 2; a sliding rod 7 is provided on the inner side of the light source panel 2, which is the side of the light source panel 2 that is close to the frame 1; the sliding rod 7 and the guide structure 8 are slidably connected in the horizontal direction.

[0048] Specifically, the guide structure 8 includes a support rail 801 and a roller 802 disposed on the inner side of the frame 1. The rotation axis of the roller 802 is a horizontal line and perpendicular to the length axis of the sliding rod 7. The bottom and top sides of the sliding rod abut against the support rail 801 and the roller 802, respectively. When installing the light source panel 2, the sliding rod 7 is first placed on the support rail 801, and then the light source panel 2 is pushed inward to make the support rail 801 slide inward along the space between the support rail 801 and the roller 802 until the connecting ring assembly 6 is near the lifting rod 4. Then, the lifting rod 4 is driven to rise so that the wedge hook 5 hooks the connecting ring assembly 6. The roller 802 can reduce the friction on the sliding rod 7, thereby reducing the sliding resistance of the sliding rod 7 and reducing the noise generated during the sliding process of the sliding rod 7.

[0049] Specifically, there are four sets of guide structures 8, which are distributed in pairs on two opposite inner sides of the frame 1. There are four sliding rods 7, which correspond one-to-one with the guide structures 8. This makes the force on the light source panel 2 more even and more stable during movement.

[0050] Furthermore, combined Figure 6 and Figure 7 As shown, the connecting ring assembly 6 includes a first support member 601, a second support member 602, a third support member 603, and a rotating shaft 604. The first support member 601 is connected to the inner side of the light source panel 2. The second support member 602 and the third support member 603 are respectively connected to the first support member 601. The two ends of the rotating shaft 604 are rotatably connected to the second support member 602 and the third support member 603, respectively. The first support member 601, the second support member 602, the third support member 603, and the rotating shaft 604 form a through cavity. When the light source panel 2 is connected to the frame 1, the outer circumferential surface of the rotating shaft 604 abuts against the driving inclined surface 501. During the lifting and lowering process of the wedge hook 5, the rotating shaft 604 will rotate due to the friction of the driving inclined surface 501. The rotating shaft 604 can reduce the friction on the driving inclined surface 501, which is beneficial to extending the service life of the connecting ring assembly 6 and reducing the lifting driving resistance of the lifting rod 4.

[0051] Furthermore, combined Figures 1 to 4As shown, the lifting drive assembly 3 has two sets, and there are two lifting rods 4, each connected to one lifting drive assembly 3 in a one-to-one correspondence. That is, one lifting drive assembly 3 corresponds to one lifting rod 4. The two lifting rods 4 are located on either side of the vertical center line of the light source panel 2. Each lifting rod 4 is connected to three wedge hooks 5, and the three wedge hooks 5 are linearly distributed along the axis of the lifting rod 4. The light source panel 2 has six connecting ring assemblies 6, and each connecting ring assembly 6 corresponds to one wedge hook 5 in a one-to-one correspondence. The two lifting rods 4 and multiple wedge hooks 5 make the force on the light source panel 2 more even, preventing the light source panel 2 from tilting, shaking, or falling off, thus allowing the canvas on the light source panel 2 to better display the advertising content.

[0052] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.

[0053] Example 3

[0054] This embodiment is a third embodiment of a pillar-mounted light box with a quick-opening and closing lock. This embodiment is similar to embodiment 2, except that, see [reference needed]. Figure 1 The light source panel 2 has four panels, which are located on different sides of the frame 1 and are detachably connected to the frame 1. Each light source panel 2 is connected to the frame 1 in the same way, as described in Embodiments 1 and 2.

[0055] Furthermore, a 90° angle is formed between two adjacent light source panels 2. The fourth light source panel 2 is not shown in the figure. Both sides of the light source panel 2 are provided with jointing slopes 201, and the jointing slopes 201 of two adjacent light source panels 2 fit together. The jointing slopes can make the two adjacent light source panels 2 fit more tightly, reduce the gap at the joint, and thus increase the effective light-emitting area of ​​the light source panel 2 as a whole.

[0056] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 2.

[0057] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described.
