Description

Technical Field

[0001] The invention relates to the technical field of signboards, and specifically relates to a wind-resistant safety signboard. Background Art

[0002] Billboard promotion is a common outdoor promotion method adopted by manufacturers. Billboards are generally placed at high places, such as roofs, or places with high traffic. The main board of the billboard is not ventilated and has a large wind-exposed area. It is easily damaged and destroyed by strong winds, or even falls from heights and injures passers-by. In order to enhance the wind resistance of the billboard device, measures such as deepening and enlarging the foundation, or thickening and strengthening the pillars and billboard frames are generally adopted. The material consumption is large and the project cost is high. Although the method of opening air leakage holes can reduce a certain impact force, the force release effect is related to the number of air leakage holes. For large billboards, a small number of air leakage holes and a small area have no practical significance, while a large number and a large area will seriously damage the integrity of the advertising surface and greatly reduce the display effect. In addition, the opening of air leakage holes brings great difficulties to the design, production and installation of advertising cloth. Summary of the invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: a wind-resistant safety sign can increase the wind-resistant capacity of the steel structure frame by means of a support plate arranged in the steel structure frame; through an adjustment plate and a rebound component, in the case of strong winds, the adjustment plate can be rotated under the blowing of the wind, so that the plane formed by the adjustment plate and the support plate forms a plurality of exhaust channels, thereby assisting exhaust and reducing the wind impact on the sign; and through the rebound component, the support plate can also be returned to the initial position after strong winds, so that the adjustment plate and the support plate form a plane without affecting the sign The effect is achieved by setting the support plate in a cone shape on the back of the signboard to form wind discharge slots between adjacent support plates. When strong winds occur at the back, the wind blows to the wind discharge slots, and the adjusting plate rotates under the driving force of the wind to open the wind discharge slots. At this time, the exhaust duct is connected to the wind discharge slots, thereby reducing the impact force of the signboard. The adjusting plate is detachably connected to the steel structure frame, so the mounting parts between the adjusting plate and the steel structure frame can be easily replaced, which is convenient for maintenance. The signboard of the present invention has strong wind resistance, complete layout, simple installation, low construction cost and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-6The present invention provides a technical solution: a wind-resistant safety sign, which includes a steel structure frame 1, in which a plurality of support plates 2 are longitudinally distributed, and an adjustment plate 3 is arranged between adjacent support plates 2, and the adjustment plate 3 is detachably connected to the steel structure frame 1, and a rebound component 4 is arranged between the adjustment plate 3 and the steel structure frame 1. In an environment with low wind force or no wind, the adjustment plate 3 cannot rotate due to the elastic action of the rebound component 4, and in an environment with strong wind, the adjustment plate 3 rotates with the strong wind, so that an exhaust channel 5 is presented between the adjacent support plates 2 and the adjustment plates 3.

[0028] See also Fig.10 , the adjustment plate 3 is in the shape of an equilateral triangle.

[0029] When installing the advertising surface, it is set on the plane formed by multiple support plates 2 and adjustment plates 3. Before designing the advertising surface, easy-to-tear openings are set at the positions where they need to be divided according to the width and number of the support plates 2 and adjustment plates 3. The advertising surface is divided into multiple pieces of the same size as the support plates 2 and adjustment plates 3 through the easy-to-tear openings. In order not to affect the situation that the advertising surface is difficult to observe under strong wind conditions, advertising surfaces identical to those on the adjustment plates 3 are set on the other two surfaces of the adjustment plates 3, which does not affect the overall display of the advertising surface even in strong wind conditions.

[0030] The signboard can receive winds from different directions, and the winds from different directions cause the adjusting plate 3 to rotate at different angles.

[0031] See also Figure 2 , 4 -6. The back of the adjusting plate 3 is conical, so as to allow the adjusting plate 3 to rotate in strong wind.

[0032] The area formed between the two support plates 2 is an air discharge slot 6, and when a strong wind blows on the back, the airflow enters the air discharge slot 6, and the airflow blows the adjustment plate 3 to rotate and open the air discharge slot 6.

[0033] See also Figure 7 , connecting pieces 7 are screwed on both sides of the adjustment plate 3, and a mounting groove 8 is provided at the mounting position of the steel structure frame 1 corresponding to the adjustment plate 3.

The connecting piece 7 extends into the limiting piece 9 and is clamped with the rebound component 4. A threaded cap 10 for limiting the limiting piece 9 in the mounting groove 8 is screwed on the connecting piece 7.

[0034] Please refer to 7 and 8. The connecting member 7 includes a first threaded rod 71, a support 72 and a second threaded rod 73 welded together in sequence. The first threaded rod 71 is screwed to the axis of the adjustment plate 3, and the threaded cap 10 is screwed to the second threaded rod 73. The screwing length of the threaded cap 10 is limited by the support 72.

[0035] See also Figure 7 and 9 The limiting member 9 includes a sleeve 91 and a connecting ear 92 symmetrically arranged on the sleeve 91 . The rebound component 4 is welded to the inside of the sleeve 91 , and the rebound component 4 is limited to rotate by the connecting ear 92 .

[0036] The threaded cap 10 is screwed onto the second threaded rod 73 and is located inside the sleeve 91 , without contacting the inner wall of the sleeve 91 .

[0037] See also Fig. 9 The rebound assembly 4 includes a limit ring 41 and a block 42. The limit ring 41 is welded to the sleeve 91 and is flush with its end. An arc-shaped notch 43 is provided on the limit ring 41. The block 42 is located at the arc-shaped notch 43. An arc spring 44 is provided between the ends of the two arc-shaped notches 43 and the block 42. The block 42 is inserted into a slot 45 provided on the second threaded rod 73 and extending to the column 72.

[0038] When the limiting member 9 is installed in the installation groove 8 , the arc-shaped notch 43 corresponds to the front end or the rear end of the steel structure frame 1 .

[0039] When the first threaded rod 71 is screwed onto the adjustment plate 3 , the slot 45 on the second threaded rod 73 corresponds to one of the corners of the adjustment plate 3 , and the slots 45 on the second threaded rod 73 at both ends of the same adjustment plate 3 to which the first threaded rod 71 is screwed are at the same position.

[0040] The inner diameter of the limiting ring 41 matches the outer diameter of the column 72 to reduce the shaking of the connecting member 7.

[0041] The angle of the arc-shaped notch 43 allows the clamping block 42 to rotate 60° in the forward or reverse direction therein.
