For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0019] like Figures 1 to 11 As shown, the anti-fall auxiliary mechanism includes a first slide rail 11 and a second slide rail 12. The first slide rail 11 and the second slide rail 12 are installed on the same end surface of the breakable support member, and the first slide rail 11 and the second slide rail 12 cooperate with each other.

[0020] In this embodiment, the easily breakable support member is the first cross beam 5 and the second cross beam 4 connected to each other, and the easily breakable portion is the connection portion between the first cross beam 5 and the second cross beam 4 .

[0021] Specifically, the first slide rail 11 is fixedly connected to the lower end surface of the first beam 5 through the fixing device 10, and the second slide rail 12 is fixedly connected to the lower end surface of the second beam 4 through the fixing device 10. When the first beam 5 is connected to the second beam 4, the first slide rail 11 and the second slide rail 12 are also connected to each other, and the matching surface between the first slide rail 11 and the first beam 5 and the matching surface between the second slide rail 12 and the second beam 4 are in the same plane. The fixing device 10 is a bolt.

[0022] The connection between the first crossbeam 5 and the second crossbeam 4 is a first interface, and the connection between the first slide rail 11 and the second slide rail 12 is a second interface. The first interface and the second interface can be staggered to further enhance the supporting stress of the first interface.

[0023] The first slide rail 11 is connected to one end away from the second slide rail 12 with the first slider 1, and the second slide rail 12 is connected to one end away from the first slide rail 11 with the second slider 2, that is, the first slider 1 and the second slider 2 are arranged opposite to each other. A connector 7 is fixedly connected between the first slide rail 11 and the second slide rail 12. The connector 7 is an aluminum plate. The connector 7 can fix the relative position of the first slider 1 and the second slider 2 to ensure that when the first interface between the first cross beam 5 and the second cross beam 4 is not broken, the first slider 1 and the second slider 2 will not be displaced, and the strength of the first interface can be further enhanced.

[0024] The first slider 1 can slide along the first slide rail 11, and the second slider 2 can slide along the second slide rail 12. When the first interface between the first beam 5 and the second beam 4 is broken, the connecting piece 7 falls off. At this time, the end connected to the first beam 5 and the second beam 4 moves downward. Under the action of gravity, the first slider 1 and the second slider 2 move toward each other along the first slide rail 11 and the second slide rail 12 respectively.

[0025] A first locking member 8 is provided on the first slider 1, and a second locking member is provided on the second slider 2. The first locking member 8 and the second locking member are arranged opposite to each other. After the first slider 1 and the second slider 2 move relative to each other, the first locking member 8 and the second locking member cooperate with each other to fix and lock the first slider 1 and the second slider 2.

[0026] Specifically, the first slider 1 is a semi-open cavity structure, including a chamber 3, a first through hole is formed on the lower side wall of the chamber 3, and the first through hole is communicated with the chamber 3; the first locking member 8 includes a cylindrical pin 15, the cylindrical pin 15 is gap-matched with the first through hole, one end of the cylindrical pin 15 is integrally formed with a base 13, the other end of the cylindrical pin 15 is integrally formed with a fixing member 14, the middle part of the cylindrical pin 15 is sleeved with an elastic component 9, the elastic component 9 is placed in a first groove opened in the first hole, the elastic component 9, the first groove and the base 13 cooperate with each other to enable the first locking member 8 to be movably connected to the first slider 1, and the elastic component 9 is a spring; the second locking member includes a locking rod 16, one end of the locking rod 16 is fixedly connected to the second locking member, the other end of the locking member is integrally formed with a clamping member 17, and the clamping member 17 and the fixing member 14 cooperate with each other. The opening of the first slider 1 is trumpet-shaped, and the opening of the first slider 1 is clearance-matched with the clamping piece 17, and the opening of the first slider 1 is clearance-matched with the locking rod 16, so that after the first slider 1 and the second slider 2 move relative to each other, the clamping piece 17 passes through the opening of the first slider 1 and cooperates with the fixing piece 14 to fix and lock the first slider 1 and the second slider 2, thereby fixing the broken part and preventing the components supported on the first beam 5 and the second beam 4 from falling off.

[0027] More specifically, the fixing member 14 is a wedge-shaped structure, the clamping member 17 is a hemispherical structure, the locking rod 16 is coaxially arranged with the clamping member 17, and the radius of the locking rod 16 is smaller than the radius of the clamping member 17. The clamping member 17, the elastic member 9, the first groove and the base 13 cooperate with each other to enable the fixing member 14 to move up and down. When the clamping member 17 contacts the fixing member 14 through the opening of the first slider 1, the fixing member 14 will be forced to move downward. When the clamping member 17 passes over the fixing member 14, the fixing member 14 moves upward under the action of the elastic member 9 to clamp the clamping part, thereby fixing and locking the first slider 1 and the second slider 2.

[0028] A limit device is provided at the end of the first slide rail 11 connected to the first slider 1, and a limit device is provided at the end of the second slide rail 12 connected to the second slider 2, so as to prevent the first slider 1 and the second slider 2 from falling off due to the tilting of the support member.

[0029] The first slide rail 11 or the second slide rail 12 is also provided with an infrared detection device 6 for monitoring the distance between the first slider 1 or the second slider 2 and the infrared detection device 6. When the first interface is broken, the first slider 1 and the second slider 2 will slide relative to each other, causing the distance between the first slider 1, the second slider 2 and the infrared detection device 6 to change. When the distance between the first slider 1 or the second slider 2 and the infrared detection device 6 exceeds a preset threshold, an early warning signal is issued to notify relevant staff to perform maintenance, thereby reducing damage caused by abnormal conditions. In this embodiment, the infrared detection device 6 is fixedly connected to the end of the second slide rail 12 away from the first slide rail 11.

[0030] The anti-fall auxiliary mechanism in this embodiment is fixedly connected to the first interface between the first cross beam 5 and the second cross beam 4, that is, the first slider 1 and the second slider 2 are located on both sides of the first interface. The anti-fall auxiliary mechanism can also be connected to other easily breakable locations as needed.

[0031] The anti-fall bracket of the LED all-in-one machine includes the above-mentioned anti-fall auxiliary mechanism, which is fixedly connected to the first interface between the first crossbeam 5 and the second crossbeam 4. When the first interface of the LED all-in-one machine bracket is broken, the anti-fall auxiliary mechanism can effectively prevent the modules, boxes and other components thereon from falling, thereby greatly improving the safety performance of the LED all-in-one machine.

[0032] The working principle of the present invention is: The anti-fall auxiliary mechanism of the present invention is installed at the breakable part of the support, the first slide rail 11 and the first slider 1 are located on one side of the breakable part, and the second slide rail 12 and the second slider 2 are located on the other side of the breakable part. When the breakable part breaks, the connecting member 7 between the first slider 1 and the second slider 2 falls off, and the first slider 1 and the second slider 2 move toward each other along the first slide rail 11 and the second slide rail 12 respectively. When the clamping member 17 of the second locking member contacts the fixing member 14 through the opening of the first slider 1, the fixing member 14 is forced to move downward, and the clamping member 17 continues to move downward. After the clamping member 17 passes over the fixing member 14, the fixing member 14 moves upward under the action of the elastic member 9 to clamp the clamping part, thereby fixing and locking the first slider 1 and the second slider 2. During the sliding process of the first slider 1 and the second slider 2, when the distance between the first slider 1 or the second slider 2 and the infrared detection device 6 exceeds the preset threshold, an early warning signal is issued to notify relevant staff to perform maintenance.
