Description

Technical Field

[0001] The present invention relates to the technical field of light boxes, specifically an outdoor light box and its auxiliary mechanism. Background Art

[0002] Outdoor light boxes convey the pattern information on the box surface through natural light and auxiliary light. They are divided into floor-standing boxes and wall-mounted boxes. Among them, the floor-standing boxes are small in size and easy to move and adjust, and are suitable for presenting information in stores.

[0003] The patent with the application number CN202420451826.9 discloses an outdoor waterproof light box, which includes a battery box fixedly installed on a fixed base. Four support rods are arranged in a rectangular array on the upper surface of the battery box. A light box is threadedly connected between the four support rods arranged in the array. A display frame is arranged on the surface of the light box, and a placement cavity is arranged inside the light box. By independently placing the lamp body installation frame inside the placement cavity, rainwater infiltration can be effectively reduced, ensuring that the light box can prevent the entry of rainwater or humid gas when displayed outdoors. And the solar panel arranged above the light box can serve as a rain baffle in rainy weather.

[0004] In order to resist strong winds, the easy-to-move floor-standing box usually has heavy objects pressed on its support feet. Although the heavy objects can stabilize the bottom of the box body, the upper half of the box body is always resisting the wind force. Coupled with long-term exposure to sunlight and rain outside, it is easy to cause the support feet of the box body to tilt, deform or even break; or give up the mobility of the floor-standing box and choose to directly fix its support feet to the ground, and there will also be a situation where the box body is damaged; at the same time, the above-mentioned patent is also like this to resist the wind force, that is, there is no mechanism designed to resist the wind force to ensure that the box body is stable on the ground without deformation and is easy to move and reposition. Therefore, an institution is needed to assist the outdoor light box to maintain convenience and stability. Summary of the Invention

[0013] As a further improvement of the technical solution, the air discharge mechanism is a wind gathering part, and the wind gathering part includes a wind gathering box, a plurality of air inlet nozzles symmetrically embedded in the front and rear surfaces of the wind gathering box, and two air discharge plates suspended below the wind gathering box. The plurality of air inlet nozzles are all communicated with the inner cavity of the wind gathering box and are inclined, the air inlet nozzles face the inclined air guide plates, and the bottom end surface of the wind gathering box is open.

[0043] Embodiment 1

[0044] Please refer to Figures 1 - 5 As shown, the present invention provides an outdoor light box, including a box frame 100 and a box surface layer 110 installed outside it. The box surface layer 110 is a spray-painted cloth or an acrylic plastic plate with a designed pattern; ventilation openings 120 are provided in the middle regions of the front and back surfaces of the box surface layer 110. A number of cross-sectional layers 121 are provided in the area of the box surface layer 110 where the ventilation openings 120 are located. By gluing the spray-painted cloth onto the outside of the box frame 100 and cutting a number of rectangular cracks at the ventilation openings 120 while keeping the connection state in the middle of the sides, the spray-painted cloth at the ventilation openings 120 can be opened when affected by the wind; by customizing an acrylic plastic panel and strip combination in the shape of the ventilation openings 120 and a number of cross-sectional layers 121 through injection molding and fixing them to the box frame 100 with screws, the acrylic strips at the ventilation openings 120 can be opened when affected by the wind; a number of cross-sectional layers 121 can deflect by 0 - 60° when facing the wind to release the wind, so that strong wind can enter the box frame 100 and be discharged from its bottom, preventing the box frame 100 from being blown down.

[0045] Furthermore, on both sides of the bottom of the box frame 100, there are symmetrically and movably connected with stabilizing frame members 130. On the top surface of the stabilizing frame members 130, there are embedded positioning members 140 which are positioned and connected with the box frame 100. The positioning members 140 are composed of a pair of parallel straight columns. On the top surfaces of both ends of the bottom cross bar of the box frame 100, there are positioning holes 101. On the top surface of the movable connection end of the stabilizing frame member 130, there is a jack 131. When the stabilizing frame member 130 is unfolded, it is positioned by inserting and mating the positioning member 140 with the positioning holes 101 and the jack 131. The stabilizing frame member 130 is bent and bent inward towards the box frame 100, such as in an arc shape or a bent shape, so as to increase the area of the bottom of the box frame 100 touching the ground, thereby increasing the wind resistance. One end of the stabilizing frame member 130 is rotatably connected with the outer end of the bottom of the box frame 100 through a pin, so that the stabilizing frame member 130 can be folded and hidden, which is beneficial to the handling and storage of the whole box frame 100.

[0046] In addition, in order to fix the deflection and movement of several cross-sectional layers 121 in the air vent 120, an auxiliary mechanism is provided, which includes a support frame 200 suspended inside the air vent 120, several air guiding plates 210 rotatably connected between the support frames 200, and two pairs of limit pins 230 for limiting the deflection angle of each air guiding plate 210. Several cross-sectional layers 121 are adhesively bonded to the corresponding air guiding plates 210, so that the two are deflected synchronously under the action of wind. Inside the box frame 100 and suspended between a pair of support frames 200, there is a wind discharging structure for blowing towards the bottom of the box frame 100 to stabilize the center of gravity of the box frame 100. Through the design of the air vent 120 and several cross-sectional layers 121, the wind on the box frame 100 will not directly act on the box surface layer 110, avoiding blowing down the box frame 100. In addition, the wind discharging structure bears the wind blowing into the box frame 100, further stabilizing the center of gravity of the box frame 100, so as to resist the wind force.

[0047] Furthermore, on both sides of the middle part of the box frame 100, there are welded positioning sleeves 102. In the middle part of the vertical section of the support frame 200, there is an inserted column 240 which is inserted and mated with the positioning sleeve 102 correspondingly, so that the support frame 200 is installed stably and quickly. At both ends of the side surface of the air guiding plate 210, there are vertically arranged limit tubes 220. Each limit tube 220 is located between each pair of limit pins 230, and the limit pins 230 are inserted into the side wall of the support frame 200. Inside the limit tube 220, there is inserted an adjusting member 221. The adjusting member 221 is a screw rod and is threadedly connected with the internal thread on the inner wall of the limit tube 220. Thus, by adjusting the exposed length of the adjusting member 221, the center of gravity of the air guiding plate 210 can be changed, so that after the air guiding plate 210 is not blown by the wind, it can automatically reset and rotate to ensure the flatness of its outer surface, so that the design patterns on the spray-painted cloth or acrylic plastic plate are aligned completely.

[0048] As Figures 6 - 11As shown, the air leakage structure is the air guiding part 300. The air guiding part 300 is composed of an air guiding plate 310 and a number of flow dividing plates 320 embedded in its front and back surfaces. An air guiding channel 321 is formed between two adjacent flow dividing plates 320. The air guiding plate 310 intercepts the wind blowing into the box frame 100 from the front and back directions, and then guides the wind to flow to the bottom of the box frame 100 through a number of air guiding channels 321 and discharges it; a pair of wind receiving plates 330 for receiving wind pressure are suspended at the bottom of the air guiding plate 310. The wind blowing into the box frame 100 is received by the pair of wind receiving plates 330, further stabilizing the center of gravity of the box frame 100, thereby resisting the wind force; the included angle between the pair of wind receiving plates 330 is 150 - 160°. Due to the inclined setting of the wind receiving plates 330, the wind can be discharged smoothly, thereby offsetting the external wind and further ensuring the stability of the box frame 100.

[0049] Furthermore, in order to offset the vibration amplitude formed by gusts of wind on the box frame 100, a bottom plate 312 sleeved with the top ports of a pair of wind receiving plates 330 is fixedly connected to the bottom of the air guiding plate 310 by bolts. Card slots 313 are opened at both side ends of the bottom plate 312, and a number of guide posts 314 are embedded in the bottom surface of the card slots 313. Springs 315 are sleeved outside the guide posts 314. A slider 331 is connected between the two sides at the top of the pair of wind receiving plates 330, and the slider 331 is slidably sleeved with the guide posts 314; so that the pair of wind receiving plates 330 offset the anti-vibration amplitude when the wind is lost by the elastic force of a number of springs 315, and the elastic force of the springs 315 is consumed by the friction between the slider 331 and the guide posts 314, enabling the wind receiving plates 330 to gradually return to their original positions.

[0050] The size of the air guiding plate 310 is at least equal to the size of the supporting frame 200. A number of supporting rods 311 are provided at the top end of the air guiding plate 310 and the bottom end of the bottom plate 312. A number of the supporting rods 311 located above are lapped on the top surface of the supporting frame 200, and a number of the supporting rods 311 located below are lapped on the frame at the bottom of the box frame 100, making the installation of the air guiding plate 310 convenient and stable.

[0051] Embodiment 2

[0052] The present invention provides an auxiliary mechanism for an outdoor light box, which is used for the above-mentioned outdoor light box and includes a box frame 100 and a box surface layer 110 installed outside it. The box surface layer 110 is a spray-painted cloth or an acrylic plastic plate with a designed pattern; ventilation openings 120 are provided in the middle regions of the front and rear surfaces of the box surface layer 110. A number of cross-sectional layers 121 are provided in the box surface layer 110 within the area of the ventilation openings 120. By gluing the spray-painted cloth to the outside of the box frame 100 and cutting several rectangular cracks with a knife at the ventilation openings 120 while keeping the middle parts of the sides connected, the spray-painted cloth at the ventilation openings 120 can be opened when affected by wind; an acrylic plastic panel and strip combination in the shape of the ventilation openings 120 and a number of cross-sectional layers 121 are customized by injection molding and fixed to the box frame 100 with screws, so that the acrylic strips at the ventilation openings 120 can be opened when affected by wind; a number of cross-sectional layers 121 can deflect by 0-60° when facing the wind to release the wind, so that strong wind can enter the box frame 100 and be discharged from its bottom, preventing the box frame 100 from being blown down by the wind.

[0053] Further, stable frame members 130 are symmetrically and movably connected to both sides of the bottom of the box frame 100. A positioning member 140 for positioning connection with the box frame 100 is embedded in the top surface of the stable frame members 130; the positioning member 140 is composed of a pair of parallel straight columns. Positioning holes 101 are provided in the top surfaces of both ends of the bottom cross bar of the box frame 100, and insertion holes 131 are provided in the top surfaces of the movable connection ends of the stable frame members 130. When the stable frame members 130 are unfolded, the stable frame members 130 are positioned through the insertion and cooperation of the positioning member 140 with the positioning holes 101 and the insertion holes 131; the stable frame members 130 are bent and bent inwardly towards the inside of the box frame 100, such as in an arc shape or a bent shape, so as to increase the area of the bottom of the box frame 100 in contact with the ground and thereby increase the wind resistance; one end of the stable frame member 130 is rotatably connected to the outer end of the bottom of the box frame 100 through a pin, so that the stable frame member 130 can be folded and hidden, which is beneficial for handling and storing the entire box frame 100.

[0054] In addition, in order to fix the deflection and movement of a number of cross-sectional layers 121 within the ventilation openings 120, an auxiliary mechanism is provided, which includes a support frame 200 suspended inside the ventilation openings 120, a number of air guiding plates 210 rotatably connected between the support frames 200, and two pairs of limit pins 230 for limiting the deflection angle of each air guiding plate 210; a number of cross-sectional layers 121 are adhesively bonded to the corresponding number of air guiding plates 210, so that the two deflect synchronously under the action of wind; a wind release structure for blowing towards the bottom of the box frame 100 to stabilize the center of gravity of the box frame 100 is suspended inside the box frame 100 and between a pair of support frames 200. Through the design of the ventilation openings 120 and a number of cross-sectional layers 121, the wind on the box frame 100 will not directly act on the box surface layer 110, preventing the box frame 100 from being blown down; in addition, the wind release structure bears the wind blowing into the box frame 100 to further stabilize the center of gravity of the box frame 100, thereby resisting the wind force.

[0055] Further, positioning sleeves 102 are welded on both sides of the middle part of the box rack 100. Insertion posts 240 are embedded in the middle of the vertical sections of the support frame 200. The insertion posts 240 are correspondingly inserted and matched with the positioning sleeves 102, so that the support frame 200 can be installed stably and quickly. At both ends of the side surface of the air guide plate 210, limiting tubes 220 are vertically arranged. Each limiting tube 220 is located between each pair of limiting pins 230, and the limiting pins 230 are inserted into the side wall of the support frame 200. An adjusting member 221 is inserted into the inside of the limiting tube 220. The adjusting member 221 is a screw rod and is threadedly connected to the internal thread of the inner wall of the limiting tube 220. Thus, by adjusting the exposed length of the adjusting member 221, the center of gravity of the air guide plate 210 can be changed, so that after the air guide plate 210 is not blown by the wind, it can automatically reset and rotate to ensure that its outer surface is flat, so that the design patterns on the spray-painted cloth or acrylic plastic plate are aligned completely.

[0056] As Figures 12 - 16 shown, the air leakage mechanism is the air gathering part 400. The air gathering part 400 includes an air gathering box 410, a plurality of air inlet nozzles 420 symmetrically embedded in the front and rear faces of the air gathering box 410, and two air leakage plates 430 suspended below the air gathering box 410. The plurality of air inlet nozzles 420 are all communicated with the inner cavity of the air gathering box 410 and are inclined. The air inlet nozzles 420 face the inclined air guide plate 210, and the bottom end face of the air gathering box 410 is open. The wind blown in from the outside is introduced through the plurality of air inlet nozzles 420 and gathered in the air gathering box 410 until it blows out from the bottom opening of the air gathering box 410 and impacts on the two air leakage plates 430 and is discharged. The two air leakage plates 430 bear the wind blown into the box rack 100, further stabilizing the center of gravity of the box rack 100, so as to resist the wind force.

[0057] In addition, the two air leakage plates 430 are hinged by a long shaft, and both ends of the long shaft are inserted into the side of the air gathering box 410. A spring piece 431 is arranged between the side ends of the two air leakage plates 430. The spring piece 431 is made of spring steel and is bent into a V shape with an included angle of 150-160°. Due to the inclined arrangement of the two air leakage plates 430, the wind can be discharged smoothly, thus offsetting the external wind and further ensuring the stability of the box rack 100. The two air leakage plates 430 can offset the anti-seismic amplitude when the wind is lost by means of the elastic force of a pair of spring pieces 431, and the elastic force of the spring pieces 431 is consumed by the friction at the hinge of the two air leakage plates 430, so that the two air leakage plates 430 can gradually reset.

[0058] It should be noted that the above embodiments are only for explaining the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
