The impact force generated is dispersed, thereby achieving the buffering effect of the lifting component 200 body. An alarm part 106 is arranged on one side of the elastic rubber pad 105. Through the setting of the alarm part 106, when the lifting component 200 collides, it can promptly make a sound by striking the gong to remind the staff inside the studio that the lifting component 200 has an abnormality. It can timely avoid the lifting component 200 from continuously colliding after buffering, thereby reducing the damage of the lifting component 200. A connecting part 107 is movably installed inside the telescopic part 103. Through the setting of the connecting part 107 and the use of the telescopic part 103, the buffering effect of the telescopic part 103 is better. The bottom of the connecting plate 102 is threadedly connected with a locking part 108, which can effectively fix the gong at the bottom of the connecting plate 102.

The first limiting rod 107a is welded with a fixed disk 107c at both ends. Through the setting of the fixed disk 107c, one end of the first spring 107b is prevented from falling off, so that both ends of the first spring 107b are effectively limited, so that the first spring 107b can effectively perform elastic movement. The first spring 107b is welded on the inner side of the two fixed disks 107c, and the other side of the first spring 107b is welded on the outer side of the two sleeves 103b.

The first limiting rod 107a cooperates with the sleeve 103b, that is, the first spring 107b is elastically deformed by the external force of the sleeve 103b, so that the sleeve 103b approaches the two ends of the first limiting rod 107a, and then squeezes the first spring 107b, so that the impact force generated when it collides can be effectively dispersed.

The limiting bolt 108b is threadedly connected to the connecting plate 102. Through the setting of the limiting bolt 108b, it is convenient to move the connecting column 108a inside the connecting plate 102, so as to adjust the position of the first clamping plate 108c and the second clamping plate 108f. One end of the connecting column 108a is connected to the first clamping plate 108c, and one end of the connecting column 108a is movably connected to the connecting rod 108d. The outer wall of the connecting rod 108d is The second spring 108e is sleeved, and the second spring 108e is arranged so that the second spring 108e can elastically limit the connecting rod 108d, that is, the connecting rod 108d can elastically move relative to the connecting column 108a through the second spring 108e, and move toward one end of the connecting rod 108d through the connecting column 108a, that is, the second spring 108e is elastically deformed by the external force of the connecting column 108a, so that the connecting rod 108d is close to one end of the connecting column 108a, and then the second spring 108e is squeezed, so that The second clamping plate 108f at the other end of the connecting rod 108d approaches one side of the connecting plate 102, so that the limiting blocks 108i welded to the bottom of the inner sides of the first clamping plate 108c and the second clamping plate 108f slide into the limiting grooves 108j symmetrically opened at both ends of the outer side of the connecting block 106a, thereby locking the connecting block 106a at the bottom of the connecting plate 102, ensuring that the gong 106b can continuously sound an alarm when the lifting assembly 200 is hit. The second clamping plate 108f is welded at one end of the connecting rod 108d, and the extension plate 108 is welded to the top of the inner side of the second clamping plate 108f. g. The outer walls of the connecting column 108a and the extension plate 108g are both welded with a second limiting rod 108h, and the outer side of the connecting plate 102 is symmetrically provided with limiting grooves that cooperate with the second limiting rod 108h. Through the cooperation between the second limiting rod 108h and the placement groove, the connecting column 108a and the connecting rod 108d will not rotate when they move horizontally inside the connecting plate 102, thereby ensuring that the first clamping plate 108c and the second clamping plate 108f can only move horizontally on both sides of the connecting plate 102, ensuring that the limiting block 108i can be smoothly inserted into the limiting groove 108j.
[0039] Furthermore, a connecting block 106a is fittedly connected to the bottom of the connecting plate 102, and a gong 106b is connected to the bottom of the connecting block 106a through a torsion spring. Through the setting of the torsion spring, the gong 106b is reset by the torsion spring after the collision, thereby achieving continuous striking of the gong 106b. The gong 106b is movably connected to the protective head 106d. Through the coordinated setting between the gong 106b and the protective head 106d, the lifting assembly 200 can emit a sound in time when a collision occurs, so that the staff nearby can be alerted and the lifting assembly 200 can be shut down in time to avoid greater damage to the lifting assembly 200. A drumstick 106c is welded to the outside of the elastic rubber pad 105, and one end of the drumstick 106c is threadedly connected to the protective head 106d. The protective head 106d is made of hard rubber, so that it can protect the gong 106b to a certain extent when striking the gong 106b, thereby avoiding damage to the gong 106b due to excessive striking force.
