Description

Technical Field

[0001] This utility model relates to the field of exhibition booth technology, and in particular to a retractable exhibition booth for urban planning. Background Technology

[0002] In the field of urban planning, the effective presentation of planning results plays a crucial role. It is related to whether the planning concept can be accurately conveyed and the planning vision can be clearly presented. To achieve this goal, a suitable exhibition booth is indispensable, and the exhibition booth has become an essential carrier for presenting planning results.

[0003] To expand the display area, current urban planning exhibition booths often adopt a multi-panel structure that can slide and extend, with the booths arranged in a sliding and staggered manner. However, when the booths are unfolded, the seams of the spliced ​​display surface are uneven. This defect is particularly prominent when posting large-scale planning maps. The difference in height at the seams will affect the display effect of the planning map, destroy the integrity of the planning map, and the planning map is more susceptible to damage at uneven seams, such as wrinkles and tears, which increases maintenance costs. Summary of the Invention

[0004] This utility model embodiment relates to a retractable urban planning display stand, which sets the top of the secondary display panel and the bottom of the main display panel as inclined structures. After the main display panel rises, the secondary display panel will move forward under the action of the corresponding structure to be flush with the main display panel, so that the two inclined surfaces coincide. After the coincidence, the secondary display panel and the main display panel together form a flat display surface. The display surface has no seams with different heights, which is convenient for displaying large-scale planning maps. The display effect will not be affected by the height difference of the seams, nor will the planning map be damaged by the height difference of the seams.

[0005] In a first aspect, this utility model provides a retractable urban planning exhibition stand, specifically comprising: a fixed support, the fixed support having an inverted T-shaped structure; a control shaft rotatably mounted inside the fixed support on the right side; a drive gear fixedly mounted on the outer circumference of the control shaft; a fixed guide rail fixedly mounted at the center of the top of the fixed support; an adjusting screw rotatably mounted on the top of the fixed support; a driven gear fixed at the bottom end of the adjusting screw; a flush guide seat fixedly mounted on the top inner side of the fixed support; a flushing block slidably mounted inside the flush guide seat; a secondary display panel fixedly mounted on the flushing block; a movable sleeve slidably mounted on the fixed guide rail; and a main display panel fixedly mounted on the front side of the movable sleeve.

[0006] Furthermore, the control shaft has a cylindrical structure; a control handwheel is fixedly installed at the right end of the control shaft.

[0007] Furthermore, the threaded portion of the adjusting screw is located inside the fixed guide rail; the driving gear and the driven gear are bevel gears, and the driving gear and the driven gear mesh with each other.

[0008] Furthermore, a restoring spring is embedded in the front side of the flush block; the other end of the restoring spring is embedded in the interior of the flush guide seat.

[0009] Furthermore, the top of the secondary display panel is inclined; the bottom of the main display panel is inclined.

[0010] Furthermore, the movable sleeve located on the right is connected to the adjusting screw via threads; when the main display panel is in the unraised state, the auxiliary display panel is located behind the main display panel.

[0011] Furthermore, when the main display panel is in the raised state, the secondary display panel is located directly below the main display panel, and the inclined surface of the secondary display panel is in contact with the inclined surface of the main display panel.

[0012] This utility model provides a retractable exhibition stand for urban planning, which has the following beneficial effects:

[0013] 1. The top of the secondary display panel and the bottom of the main display panel are designed with an inclined structure. When the main display panel rises, the secondary display panel moves forward under the drive of a specific structure until it is completely flush with the main display panel. At this time, the inclined surfaces of the two panels are precisely overlapped, forming a flat and seamless display surface. This avoids display defects caused by seams and height differences in the display surface, and also eliminates the risk of the planning map being damaged due to seam problems.

[0014] 2. After the secondary display panel is aligned with the main display panel and the display task is completed, the main display panel is lowered. Under the interaction of the inclined surfaces, the secondary display panel is pushed back smoothly and hidden behind the main display panel again. This design not only ensures the flatness of the display surface when it is unfolded, but also makes the storage operation simple and does not require any extra complicated steps.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please refer to Figures 1 to 5 Example 1:

[0027] This utility model proposes a retractable exhibition stand for urban planning, comprising: a fixed support 1, which has an inverted T-shaped structure; a control shaft 2 rotatably mounted inside the right side of the fixed support 1; a drive gear 3 fixedly mounted on the outer circumference of the control shaft 2; a fixed guide rail 5 fixedly mounted at the center of the top of the fixed support 1; an adjusting screw 6 rotatably mounted on the top of the fixed support 1; a driven gear 7 fixedly mounted at the bottom end of the adjusting screw 6; a flush guide seat 8 fixedly mounted on the top inner side of the fixed support 1; a flushing block 9 slidably mounted inside the flush guide seat 8; a secondary display panel 11 fixedly mounted on the flushing block 9; a movable sleeve 12 slidably mounted on the fixed guide rail 5; and a... The main display panel 13 is operated by manually rotating the handwheel 4, which causes the control shaft 2 and the drive gear 3 to rotate. The drive gear 3, in conjunction with the driven gear 7, drives the adjusting screw 6 to rotate. During rotation, the adjusting screw 6 uses its threads to convert the rotational force into an upward force, which is provided to the movable sleeve 12. This causes the movable sleeve 12 to move the main display panel 13 upward. After the main display panel 13 moves upward to a certain position, it will release its obstruction of the secondary display panel 11, allowing the secondary display panel 11 to move forward under the action of the restoring spring 10. This causes the inclined surface of the secondary display panel 11 to fit against the inclined surface of the main display panel 13, so that the secondary display panel 11 and the main display panel 13 together form a large and flat display surface structure.

[0028] In Example 2, based on Example 1, the control shaft 2 is a cylindrical structure; a control handwheel 4 is fixedly installed on the right end of the control shaft 2; the threaded part of the adjusting screw 6 is inside the fixed guide rail 5; the driving gear 3 and the driven gear 7 are bevel gears, and the driving gear 3 and the driven gear 7 mesh with each other; one end of the restoring spring 10 is embedded in the front side of the flushing block 9; the other end of the restoring spring 10 is embedded in the flushing guide seat 8. When it is necessary to reduce the display area, the control handwheel 4 is manually reversed, so that the adjusting screw 6 reverses under the cooperation of the corresponding structure and moves the movable sleeve 12 and the main display panel 13 downward. During the movement, the inclined surface of the main display panel 13 will push the inclined surface of the secondary display panel 11, so that the secondary display panel 11 will start to move backward due to the push of the inclined surface and hide behind the main display panel 13 for the second time. It will not affect the descent of the main display panel 13. From this point on, the display stand is completed solely by the main display panel 13.

[0029] In Example 3, based on Example 2, the top of the secondary display panel 11 is inclined; the bottom of the main display panel 13 is inclined; the movable sleeve 12 on the right side is connected to the adjusting screw 6 via threads; when the main display panel 13 is not raised, the secondary display panel 11 is located behind the main display panel 13; when the main display panel 13 is raised, the secondary display panel 11 is located directly below the main display panel 13, and the inclined surface of the secondary display panel 11 is in close contact with the inclined surface of the main display panel 13. A telescopic sliding structure is formed by the fixed bracket 1, the fixed guide rail 5, and the movable sleeve 12. This telescopic sliding structure allows adjustment of the display area of ​​the booth, setting the top of the secondary display panel 11 and the bottom of the main display panel 13 to be inclined. After the main display panel 13 rises, the secondary display panel 11 will move forward and become flush with the main display panel 13 under the action of the corresponding structure, so that the two inclined surfaces overlap. After overlapping, the secondary display panel 11 and the main display panel 13 together form a flat display surface without uneven seams, which is convenient for displaying large-scale planning drawings. The display effect will not be affected by the height difference of the seams, nor will the planning drawings be damaged by the height difference of the seams. After the secondary display panel 11 is flush with the main display panel 13, the main display panel 13 will descend, and the main display panel 13 will descend under the action of the inclined surface, pushing the secondary display panel 11 back to be hidden behind the main display panel 13. In this way, the display surface can be guaranteed to be sufficiently flat after unfolding, and the storage work is relatively simple without the need for other extra steps.

[0030] Working principle: When the display area needs to be increased, the handwheel 4 is manually rotated, causing the control shaft 2 and the drive gear 3 to rotate. The drive gear 3, in conjunction with the driven gear 7, rotates the adjusting screw 6. During rotation, the adjusting screw 6 uses its threads to convert rotational force into upward force, which is then supplied to the movable sleeve 12. This causes the movable sleeve 12 to move the main display panel 13 upwards. After the main display panel 13 has moved to a certain position, it releases its obstruction of the secondary display panel 11, allowing the secondary display panel 11 to move forward under the action of the return spring 10. This causes the inclined surface of the secondary display panel 11 to align with the inclined surface of the main display panel 13, thus increasing the display area. The display panel 11 and the main display panel 13 together form a large and flat display surface structure, which can increase the display area. When it is necessary to reduce the display area, the handwheel 4 is manually reversed, which causes the adjusting screw 6 to reverse and move the movable sleeve 12 and the main display panel 13 downward with the cooperation of the corresponding structure. During the movement, the inclined surface of the main display panel 13 will push against the inclined surface of the secondary display panel 11, causing the secondary display panel 11 to move backward due to the push of the inclined surface, and then hide behind the main display panel 13. This will not affect the descent of the main display panel 13. From this point on, the display stand only relies on the main display panel 13 to complete the display, thus reducing the display area.
