Description

Technical Field

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

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

[0003] The patent with application number CN202420451826.9 discloses an outdoor waterproof light box, including a battery box fixedly mounted 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 of 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 placing the lamp body mounting frame independently inside the placement cavity, rainwater infiltration can be effectively reduced, ensuring that the light box can prevent rainwater or humid gas from entering when displayed outdoors, and the solar panel arranged above the light box can be used as a rain baffle in rainy weather.

[0004] In order to resist strong winds, portable floor boxes usually have heavy objects placed on their supporting feet. Although the heavy objects can stabilize the bottom of the box, the upper part of the box is always resisting the wind, and the long-term exposure to the sun and rain outside can easily cause the supporting feet of the box to tilt, deform, or even break. Alternatively, if the mobility of the floor box is abandoned and the supporting feet are directly fixed to the ground, the box may be damaged. At the same time, the above-mentioned patent can also resist wind in this way, that is, there is no mechanism designed to resist wind to ensure that the box is stable and does not deform when it is on the ground and is easy to move, reposition, and adjust. Therefore, it is necessary to provide a mechanism to assist the outdoor light box in maintaining convenience and stability. Summary of the invention

The plurality of air inlet nozzles are connected to the inner cavity of the air gathering box and are arranged at an inclination. The air inlet nozzles face the inclined air guide plate, and the bottom end surface of the air gathering box is open.

[0014] As a further improvement of the technical solution, the two air leakage plates are hinged by a long axis and the two ends of the long axis are plugged into the side of the wind collecting box, and a spring sheet is arranged between the side ends of the two air leakage plates, and the spring sheet is bent and its included angle is 150-160°.

[0039] Furthermore, stabilizing members 130 are symmetrically and movably connected on both sides of the bottom of the box frame 100, and a positioning member 140 that is positioned and connected to the box frame 100 is embedded on the top surface of the stabilizing member 130; the positioning member 140 is composed of a pair of parallel straight columns, and positioning holes 101 are provided on the top surfaces of both ends of the bottom cross bar of the box frame 100, and a plug hole 131 is provided on the top surface of the movable connection end of the stabilizing member 130.

Through the design of the air vent 120 and the plurality of cross-sectional layers 121, the wind appearing in the box frame 100 will not directly act on the box surface layer 110, thereby avoiding blowing down the box frame 100; in addition, the wind blowing into the box frame 100 is borne by the air discharge structure, so as to further stabilize the center of gravity of the box frame 100 and resist the wind force.

[0048] Furthermore, positioning sleeves 102 are welded on both sides of the middle part of the box frame 100, and a plug post 240 is embedded in the middle part of the vertical section of the support frame 200.
