Description

Technical Field

[0001] This utility model belongs to the field of subway advertising light box technology, specifically a retractable subway advertising light box display extension structure. Background Technology

[0002] Subway advertising light boxes are advertising display media installed inside subway stations or train carriages. They are typically used to attract passengers' attention and display advertising content. They utilize the brightness and color of light to make the advertising content more eye-catching within the station or carriage, thus attracting passengers' attention. Existing subway advertising light boxes usually use display screens to display advertisements. However, in practical use, some subway advertising light boxes need to display too much content, resulting in a large size that is inconvenient to transport and relocate. Therefore, there is a need to propose a retractable subway advertising light box display extension structure to solve the above problems. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a retractable subway advertising lightbox display extension structure, which solves the problem that existing subway advertising lightboxes usually use display screens to display advertisements, but in actual use, some subway advertising lightboxes need to display too much content, resulting in large size and inconvenience for transportation and transfer.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a retractable subway advertising lightbox display extension structure, comprising a box body, two mounting boxes inside the box body, an outer frame inside the mounting box, a second display screen assembly fixedly connected inside the outer frame, sliders fixedly connected to the top and bottom of the mounting boxes, a bidirectional lead screw inside the box body, the bidirectional lead screw being rotatably connected to the box body via bearings, a fixing rod fixedly connected inside the box body, and four sliders, two of which are threadedly connected to the bidirectional lead screw and the other two sliders being slidably connected to the fixing rod, and a first display screen assembly fixedly connected to the front of the box body.

[0005] As a further embodiment of this utility model: the top and bottom of the box are provided with sliding grooves, and the slider is slidably connected in the sliding grooves.

[0006] As a further embodiment of this utility model: a knob is fixedly connected to one end of the bidirectional lead screw, and the knob has several grooves.

[0007] As a further embodiment of this utility model: countersunk holes are provided at the top and bottom of the mounting box, and screws are installed inside the countersunk holes.

[0008] As a further embodiment of this utility model: limit holes are provided at the top and bottom of the outer frame, and the screw is threaded into the limit holes.

[0009] As a further embodiment of this utility model: the number of the second display screen components is two, and the two second display screen components are symmetrically arranged about the middle of the housing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This retractable subway advertising lightbox display extension structure comprises a second display screen assembly, mounting boxes, a bidirectional lead screw, sliders, a housing, and a knob. When the two second display screen assemblies need to be extended, rotating the knob rotates the bidirectional lead screw. Because the threads on both sides of the bidirectional lead screw are in opposite directions, and two sliders are threaded onto the lead screw, rotating it causes the two mounting boxes and the second display screen assemblies to move away from each other, thus extending the two second display screen assemblies from inside the housing. When the two second display screen assemblies need to be retracted, rotating the knob in the opposite direction rotates the bidirectional lead screw. Because the threads on both sides of the bidirectional lead screw are in opposite directions, and two sliders are threadedly connected to the bidirectional lead screw, when the bidirectional lead screw reverses, it causes the two mounting boxes and the second display screen assembly to move closer to each other, thereby retracting the two second display screen assemblies into the housing. This display extension structure allows the second display screen assembly and the mounting box to extend and retract. When the second display screen assembly extends, the combined action of the second display screen assembly and the first display screen assembly increases the display content. When the second display screen assembly and the mounting box retract, the overall volume of the structure is reduced, facilitating transportation and transfer.

[0012] This retractable subway advertising lightbox features an extended display structure. It includes a mounting box, countersunk holes, screws, limiting holes, an outer frame, and a second display screen assembly. To disassemble the second display screen assembly, it is first extended. Then, the screws are tightened to disengage from the limiting holes, releasing the assembly from its fixed position. To install the second display screen assembly, the outer frame is placed inside the mounting box, aligning the limiting holes with the countersunk holes. Screws are then placed in the countersunk holes and tightened until they are fully inserted into the limiting holes, securing the outer frame and the second display screen assembly. This modular design facilitates the disassembly and installation of the second display screen assembly, making maintenance and repair easier. Attached Figure Description

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a retractable subway advertising light box display extension structure, including a box body 1, two mounting boxes 2 are provided inside the box body 1, and sliding grooves 3 are provided at the top and bottom of the box body 1. A slider 4 is slidably connected in the sliding groove 3. An outer frame 11 is provided inside the mounting box 2, and a second display screen assembly 9 is fixedly connected inside the outer frame 11.

[0020] Slider 4 is fixedly connected to both the top and bottom of the mounting box 2. A bidirectional lead screw 7 is installed inside the housing 1. The bidirectional lead screw 7 allows for the extension and retraction of the second display assembly 9 and the mounting box 2 through its rotation. When the second display assembly 9 extends, the combined effect of the second display assembly 9 and the first display assembly 6 increases the displayed content. When the second display assembly 9 and the mounting box 2 retract, the overall volume of the structure is reduced, facilitating transportation and transfer. A knob 5 is fixedly connected to one end of the bidirectional lead screw 7. The knob 5 has several grooves. Several grooves are provided to increase friction, making it easier for personnel to rotate knob 5 and improving operational convenience. The bidirectional lead screw 7 is rotatably connected to the housing 1 via bearings. A fixed rod 8 is fixedly connected inside the housing 1. Because of the fixed rod 8, when the mounting box 2 moves, the slider 4 will slide on the fixed rod 8. The fixed rod 8 plays a role in limiting and guiding the slider 4 and the mounting box 2, improving the stability and accuracy of the movement of the mounting box 2. Moreover, when the bidirectional lead screw 7 rotates, the limiting function of the fixed rod 8 can prevent the mounting box 2 from rotating with the bidirectional lead screw 7, thereby ensuring the normal movement of the mounting box 2.

[0021] There are four sliders 4, two of which are threaded to the bidirectional lead screw 7 and the other two are slidably connected to the fixed rod 8. There are two second display screen assemblies 9, which are symmetrically arranged about the middle of the housing 1.

[0022] The front of the housing 1 is fixedly connected to the first display screen assembly 6. Because the first display screen assembly 6 and the second display screen assembly 9 are provided, the first display screen assembly 6 and the second display screen assembly 9 can promote different content respectively under the mutual cooperation of the first display screen assembly 6 and the second display screen assembly 9, and can promote the product from multiple directions and angles, thereby improving the promotion effect. The top and bottom of the mounting box 2 are provided with countersunk holes 13. Because of the countersunk holes 13, the countersunk holes 13 serve to accommodate screws 12, so that the top and bottom of the mounting box 2 are level, and prevent the screws 12 from interfering with the housing 1 when the mounting box 2 moves. The screws 12 are installed inside the countersunk holes 13. The top and bottom of the outer frame 11 are provided with limit holes 10, and the screws 12 are threaded into the limit holes 10.

[0023] The working principle of this utility model is as follows:

[0024] When it is necessary to extend the two second display screen assemblies 9, turn the knob 5 to drive the bidirectional lead screw 7 to rotate. Since the threads on both sides of the bidirectional lead screw 7 are in opposite directions, and two sliders 4 are threadedly connected to the bidirectional lead screw 7, when the bidirectional lead screw 7 rotates, it will cause the two mounting boxes 2 and the second display screen assemblies 9 to move away from each other, thereby extending the two second display screen assemblies 9 out of the housing 1. When it is necessary to retract the two second display screen assemblies 9, turn the knob 5 in the opposite direction to drive the bidirectional lead screw 7 to rotate. Since the threads on both sides of the bidirectional lead screw 7 are in opposite directions, and two sliders 4 are threadedly connected to the bidirectional lead screw 7, when the bidirectional lead screw 7 reverses, it will cause the two mounting boxes 2 and the second display screen assemblies 9 to move closer to each other, thereby retracting the two second display screen assemblies 9 back into the housing 1.

[0025] When it is necessary to disassemble the second display assembly 9, first make the second display assembly 9 in the extended state. At this time, turn the screw 12 to disengage the screw 12 from the inside of the limiting hole 10, thereby releasing the fixed state of the second display assembly 9. At this time, the second display assembly 9 can be disassembled. When it is necessary to install the second display assembly 9, first place the outer frame 11 inside the mounting box 2 so that the limiting hole 10 is aligned with the countersunk hole 13. Then place the screw 12 inside the countersunk hole 13 and turn the screw 12 until the screw 12 is screwed into the limiting hole 10 to fix the outer frame 11 and the second display assembly 9, thus completing the installation of the second display assembly 9.
