[0026] Beneficial effect - multiple reminder functions: The use of multiple sets of magnet structures enables the cross bar to produce a specific sound during the vertical movement through the movement of the first magnet and the magnetic attraction and collision effect between it and the second magnet, thereby achieving a corresponding sound reminder effect to remind construction workers of the contact and collision with the edge protection mechanism. At the same time, the use of the second magnet can also assist in the splicing and fixation of multiple brackets. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 9 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problems existing in the prior art, the following solutions are disclosed in this embodiment. Figure 1-Figure 2 As shown, it includes a bracket 1 constituting the main body of the protection mechanism and a baffle 2 located at the top of the bracket 1, wherein the bottom end of the bracket 1 is fixed in the building plane and cooperates with the baffle 2 to achieve a protection effect, and two adjacent brackets 1 can be installed and spliced ​​and expanded by bolts. A buffer mechanism is also arranged on the front of the bracket 1, wherein the buffer mechanism is used to provide a collision buffering effect and provide unfolding anti-drop protection during a collision. The buffer mechanism includes a buffer plate 3 and a cross bar 4 installed on its side, and the buffer plate 3 and the cross bar 4 are arranged to protrude from the front of the bracket 1, and at the same time, the back of the buffer plate 3 is fixedly connected to the outer end of the slide bar 5, and the horizontally distributed slide bar 5 is slidably installed on the back plate 7 fixed in the bracket 1 through a spring 6. The content disclosed in this scheme is mainly that in the process of building construction, the edge protection mechanism is used to effectively buffer and protect people or equipment that may occur, and the protection effect is mainly achieved by the buffer plate 3. After it is subjected to force, the slide bar 5 on its back will slide on the back plate 7 by compressing the spring 6, thereby buffering the impact force received by people or equipment, so as to achieve the purpose of anti-collision protection of the edge guardrail or people or equipment.

[0031] Embodiment 2: Figure 3 and Figure 4The scheme shown in the embodiment is further developed on the basis of the above scheme, and the main content is composed of a lever 8, and a toggle mechanism is also provided on the cross bar 4, wherein the toggle mechanism toggles the force applying party through the force movement of the cross bar 4, and the toggle mechanism includes a lever 8 with an obtuse angle, and the bottom end of the lever 8 is non-rigidly installed on the back of the cross bar 4, wherein the corner of the lever 8 is distributed toward the back of the bracket 1, and the lever 8 will be blocked by the bracket 1 and deflected toward the cross bar 4 after moving toward the back of the bracket 1, and the lever 8 itself has A certain angle is formed, and the bracket 1 has a plurality of rod structures distributed vertically and horizontally. The lever 8 has the above-mentioned rod structure above the corner, and the bottom end of the lever 8 is not rigidly connected. Therefore, when the lever 8 follows the cross bar 4 and is synchronously moved by the force-applying party, the lever 8 will be blocked by the rod structure and move the force-applying party away from the bracket 1. The reason why the lever 8 with a certain angle is used is that under the same rotation angle, the top end of the lever 8 with a corner will be deflected to a position farther away from the bracket 1, thereby achieving a better protection effect.

[0032] Embodiment 3: The solution disclosed in this embodiment is still to improve the protection effect by expanding the overall protection area of ​​the edge protection mechanism. Different from the traditional method of using a fixed expansion structure after the initial installation, this solution adopts a more flexible method. Its flexibility is mainly reflected in that the expansion structure will only be actively deployed to improve the protection effect after the bracket 1 is stressed, and will not affect the normal construction operation in the normal state and the construction space. Figure 5-Figure 7 As shown, a cross bar 9 is also installed vertically and slidably at the top of the bracket 1, and the cross bar 9 is also connected to a driving mechanism, wherein the driving mechanism is used to drive the cross bar 9 to move in the vertical direction and generate a driving force through the movement of the buffer plate 3. The driving mechanism includes a vertically distributed top rod 10 and a push rod 12 rotatably installed at its tail end, and the bottom end of the push rod 12 is rotatably installed on the back of the buffer plate 3 through a pin shaft 13, wherein the top rod 10 is vertically slidably installed in the bracket 1 through an elastic member 11. After the buffer plate 3 is subjected to force, the buffer plate 3 will not only move in the bracket 1 through the slide rod 5 It will not only slide, but also use its own sliding to push the push rod 12. During this process, the top and bottom ends of the push rod 12 are deflected on the top rod 10 and the buffer plate 3 respectively, and at the same time push the top rod 10 to move upward. At this time, the cross bar 9 that fits on the top of the bracket 1 in the initial state will extend upward. Therefore, when the construction workers accidentally collide with the edge protection bracket 1 from the construction space, the lever 8 will push the personnel toward the construction space, and the cross bar 9 will also expand the coverage area of ​​the protection mechanism by moving upward, thereby achieving a better effect of preventing personnel and equipment from falling.

[0033] The solution disclosed in this embodiment is still expanded on the basis of the movement of the buffer plate 3. The purpose of expanding this solution is to enable the edge protection mechanism to emit a specific sound to remind personnel in the case of poor visibility or other special circumstances in the construction space, such as Figure 5 and Figure 8 As shown, the edge protection mechanism also includes a reminder mechanism, wherein the reminder mechanism generates a specific sound through the movement of the buffer plate 3 to achieve a reminder collision effect. The reminder mechanism includes an air cylinder 15 and a valve plate 16 slidably installed inside the air cylinder 15. The top of the valve plate 16 is connected to the push rod 10 located below the buffer plate 3. The push rod 10 is also connected to the buffer plate 3 through a push rod 12 and a pin shaft 13. At the same time, the upper part of the valve plate 16 is a non-enclosed space, and the lower internal space is connected to the hollow structure inside the bracket 1. The hollow structure is connected to the air hole 14 opened on the surface of the bracket 1, and the air hole 14 is equipped with a metal sheet distributed in the blowing direction of the air flow. When the buffer plate 3 moves, it will also push the push rod 10 below it to move. Therefore, the valve plate 16 at the bottom end of the push rod 10 will move synchronously and generate airflow, which will be blown to the air hole 14 through the hollow structure inside the bracket 1. At this time, the airflow collides and rubs with the metal sheet in the air hole 14 at a high speed, causing the metal sheet to vibrate and emit a sound of a specific frequency, thereby achieving a reminder effect.

[0034] Embodiment 4: This embodiment differs from the above embodiments in that the reminder mechanism is different, such as Fig. 9 As shown, the reminder mechanism includes a second magnet 19 arranged inside the bracket 1 and a first magnet 18 arranged to be attracted to each other. The first magnet 18 is connected to the bottom end of the guide rod 17 by a hanging rope, and the top end of the guide rod 17 slides through the bracket 1 and is fixed on the cross bar 9. At the same time, the opposite surfaces of the second magnets 19 of the two adjacent edge protection brackets 1 are arranged to attract each other. It is known that the cross bar 9 will move upward after the buffer plate 3 is subjected to force. During this process, the guide rod 17 moves synchronously with the cross bar 9 and pulls the first magnet 18 at the bottom end to move synchronously by the hanging rope. During the movement of the first magnet 18, its left and right side surfaces intermittently collide, absorb and separate with the two groups of staggered second magnets 19 on the left and right, thereby generating a corresponding sound to produce a reminder effect. At the same time, the use of the second magnet 19 can also provide an auxiliary effect of magnetic docking and limiting when multiple edge protection mechanisms are used for docking and connection.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
