Description

An advertising installation frame Technical Field

[0001] This utility model relates to the field of advertising construction technology, and in particular to an installation frame for advertising construction. Background Technology

[0002] Advertising, in its sense, can be divided into broad and narrow definitions. Broadly defined, advertising refers to advertising that is not for profit, while narrowly defined, advertising refers to advertising that is for profit. Advertising construction not only involves the installation of advertisements but also includes the replacement of existing advertisements.

[0003] A search of Chinese Patent Publication No. CN222337873U reveals a billboard mounting frame, relating to the field of billboard installation technology. The frame includes a column and a clamping structure. The column has an internal linkage rod with threaded rods at both ends. One end of one threaded rod has two gears, with a control handwheel plugged into the top of one gear. One end of the threaded rod has a round rod, and the other end has a prism rod. Both clamping structures include support columns, with movable carriages slidably connected to both ends of the support columns. A positioning plate is machined on one side of the movable carriage. The key technical point is that by rotating the control handwheel at the bottom of the column, the two gears control the rotation of the prism rod, causing the threaded rods at both ends of the linkage rod to rotate synchronously. By adjusting the threaded connection between the two threaded rods and the two support columns, the billboard can be clamped and fixed, without being limited by the billboard height, worker height, or column length, making it highly applicable.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned mounting frame: In the prior art, when installing billboards, the billboard is placed inside the two positioning plates of the bottom clamping structure, so that the back of the billboard is in contact with the surface of the column and the movable slide. If there is windy weather, one worker is required to support the billboard. If it is not supported, the billboard may be blown over by the wind. Another worker needs to turn the control handwheel. One person is unable to complete the billboard installation due to windy weather. Based on this, this utility model designs an installation frame for advertising construction to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide an installation frame for advertising construction, so as to solve the problem mentioned in the background art that when encountering windy weather, one worker needs to support the billboard while another worker needs to turn the control handwheel, making it difficult for one person to complete the billboard installation due to windy weather.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] This utility model provides an advertising installation frame as shown in Figures 1-3, including a base 1. A rectangular rod 2 is fixedly installed on the top of the base 1. A crossbar 3 is slidably connected inside the rectangular rod 2. A second crossbar 16 and a suction cup 5 are fixedly installed on both sides of the rectangular rod 2. A limit plate 4 is fixedly installed on one side of the first crossbar 3 and the second crossbar 16. The bottom of the billboard is placed in the groove of the limit plate 4 on the second crossbar 16, so that the back of the billboard is in close contact with the suction cup 5. A connecting pipe 6 is fixedly installed on the back of the rectangular rod 2. The suction cup 5 is connected to the connecting pipe 6 through the pipe. An air extraction component 7 and a ventilation component 8 are respectively provided on the top of the base 1. One end of the air extraction component 7 and the ventilation component 8 are respectively connected to the connecting pipe 6. The worker steps on the air extraction component 7 to extract the air from the connecting pipe. Gas is drawn from the suction cup 5 through the connecting pipe 6, causing the suction cup 5 to firmly adhere to the billboard. A power component 10 is installed inside the base 1. A threaded rod 9 is rotatably connected inside the rectangular rod 2. The bottom end of the threaded rod 9 passes through the base 1 and connects to the power component 10. A crossbar 3 is threadedly connected to the threaded rod 9. When the operator rotates the power component 10, the threaded rod 9 rotates, causing the crossbar 3 to move downwards. The crossbar 3 then moves the limiting plate 4 downwards, and the groove on the limiting plate 4 engages with the top of the billboard, achieving clamping and installation of the billboard. Finally, the operator steps on the ventilation component 8, allowing external gas to enter the connecting pipe 6. The gas in the connecting pipe 6 then enters the suction cup 5 through the pipe, preventing the suction cup 5 from adhering to the back of the billboard.

[0024] In this embodiment, as shown in Figures 1, 2, and 3, the air extraction assembly 7 includes a foot-operated air pump 71 and a connecting pipe 72. The foot-operated air pump 71 is located at the top of the base 1, and its extraction end is connected to the connecting pipe 72. One end of the connecting pipe 72 is connected to the connecting pipe 6. The ventilation assembly 8 includes a foot valve 81 and a connecting pipe 82. The foot valve 81 is located at the top of the base 1, and its ventilation end is connected to the connecting pipe 82. One end of the connecting pipe 82 is connected to the connecting pipe 6. The power assembly 10 includes a gear 101 and a gear 102. The gear 101 and gear 102 are rotatably connected inside the base 1 and mesh with each other. The bottom end of the threaded rod 9 penetrates the base. 1. Connected to gear 2 102, when disassembling the billboard, the worker steps on the foot pedal air pump 71 to draw gas from the connecting pipe 6 through the connecting pipe 2 82. The connecting pipe 6 draws gas from the suction cup 5 through the pipe, causing the suction cup 5 to adhere to the billboard. The worker rotates the handwheel on the base 1 to drive gear 101 to rotate. Gear 101 drives the threaded rod 9 to rotate through gear 2 102. The threaded rod 9 drives the crossbar 3 to move upward, causing the limiting plate 4 on the crossbar 3 to move upward and disengage from the top position of the billboard. At this time, the worker supports the billboard, and then the worker steps on the foot pedal valve 81. External gas enters the connecting pipe 6 through the connecting pipe 2 82. The gas in the connecting pipe 6 enters the suction cup 5 through the pipe, so that the suction cup 5 does not adhere to the back of the billboard, and the billboard can be disassembled.

[0025] In this embodiment, as shown in Figure 2, slide rails 11 are fixedly installed on both sides of the inner wall of the rectangular rod 2. The crossbar 3 is slidably connected to the slide rails 11. During the up-and-down movement of the crossbar 3, it slides through the slide rails 11 to guide the crossbar 3 to rise and fall.

[0026] In this embodiment, as shown in Figure 1, a telescopic rod 12 is slidably connected through the interior of the first horizontal bar 3 and the second horizontal bar 16. A limiting plate 2 13 is fixedly installed on one side of the telescopic rod 12. A through groove 14 is opened through the top of the telescopic rod 12, the first horizontal bar 3 and the second horizontal bar 16 respectively. A pin 15 is inserted into the inside of the through groove 14. The telescopic rod 12 on the first horizontal bar 3 and the second horizontal bar 16 is moved to a suitable position, and the pin 15 is inserted into the through groove 14 to limit the telescopic rod 12. The limiting plate 2 13 limits the corners on both sides of the billboard.

[0027] The working principle of this utility model is as follows: This utility model is an installation frame for advertising construction. First, when using it, the bottom of the billboard is placed in the groove of the upper limit plate 4 of the horizontal bar 2 16, so that the back of the billboard is in close contact with the suction cup 5. The worker steps on the foot pedal air pump 71 to draw gas from the connecting pipe 6 through the connecting pipe 2 82. The connecting pipe 6 draws gas from the suction cup 5 through the pipe, so that the suction cup 5 tightly adheres to the billboard. At this time, the billboard is in the limited position state.

[0028] The worker rotates the handwheel on the base 1, which drives gear 101 to rotate. Gear 101 drives threaded rod 9 to rotate via gear 2 102. Threaded rod 9 drives crossbar 3 to move downwards. Crossbar 3 drives limiting plate 4 to move downwards. The limiting plate 4 engages with the top of the billboard through the groove, thus clamping and installing the billboard. Finally, the worker steps on foot valve 81, and external gas enters the connecting pipe 6 through connecting pipe 2 82. The gas in connecting pipe 6 enters the suction cup 5 through the pipe, preventing the suction cup 5 from adsorbing the back of the billboard.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
