DETAILED DESCRIPTION

[0020] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a combined smoke barrier vertical wall, including a fixed smoke barrier vertical wall 1, a groove 6 is opened at the bottom of the fixed smoke barrier vertical wall 1, a slide plate 8 is slidably connected to the inner wall of the groove 6, a movable smoke barrier vertical wall 4 is fixed to the bottom of the slide plate 8, and a linkage component 5 is arranged inside the fixed smoke barrier vertical wall 1, and the linkage component 5 includes: a motor 50, a fixed plate 51, a bevel gear 1 52, a bevel gear 2 53, a threaded rod 54, a transmission member 55, a groove 2 550, a contact plate 551, a movable plate 552, and a torsion spring 553.

[0021] The motor 50 is fixed to the top of the inner wall of the groove 16, and a fixing plate 51 is fixed to the top of the inner wall of the groove 16. The right side of the fixing plate 51 is rotatably connected to the bevel gear 1 52, and the top of the inner wall of the groove 16 is rotatably connected to the bevel gear 2 53. The bevel gear 1 52 meshes with the bevel gear 2 53. The output shaft of the motor 50 passes through the fixing plate 51, and the output shaft of the motor 50 is rotatably connected to the fixing plate 51. The top of the inner wall of the groove 16 is rotatably connected to a threaded rod 54, and the top of the threaded rod 54 is fixedly connected to the bottom of the bevel gear 2 53. The bottom of the threaded rod 54 passes through the slide plate 8 and the movable smoke barrier vertical wall 4, and the threaded rod 54 is threadedly connected to the slide plate 8 and the movable smoke barrier vertical wall 4. The linkage assembly 5 also includes a transmission member 55, and the transmission member 55 includes a groove 2 550. The groove 2 550 is opened on the side of the bevel gear 1 52 close to the motor 50. The inner wall of the groove 2 550 is fixed with a contact plate 551. The output shaft extends into groove 2 550, and a movable plate 552 is hinged on the surface of the output shaft of the motor 50. A torsion spring 553 is fixed on the surface of the movable plate 552. The end of the torsion spring 553 away from the movable plate 552 is fixed to the surface of the output shaft of the motor 50. When the motor 50 is turned on, the output shaft of the motor 50 rotates, driving the movable plate 552 to rotate. At this time, the surface of the movable plate 552 contacts the surface of the contact plate 551, thereby causing the bevel gear 1 52 to rotate, thereby driving the bevel gear 2 53 to rotate, causing the threaded rod 54 to rotate. At this time, the slide plate 8 and the movable smoke barrier wall 4 move downward for adjustment without manual adjustment by personnel, thereby increasing its efficiency. The threaded rod 54 is reversed to retract the movable smoke barrier wall 4. When the top of the slide plate 8 contacts the fixed plate 51, if the personnel does not turn off the motor 50 in time, the flipping of the movable plate 552 will not affect the normal operation of the motor 50, thereby preventing the motor 50 from being damaged.

[0022] The surface of the fixed smoke shielding vertical wall 1 is provided with heat dissipation holes 3 to facilitate heat dissipation of the motor 50 .

[0023] A mounting seat 2 is fixed on the surface of the fixed smoke barrier vertical wall 1, which is convenient for stable installation.

[0024] A stabilizing plate 7 is fixed to the bottom of the fixed smoke barrier 1, and a brush is fixed to the surface of the stabilizing plate 7. One end of the brush away from the stabilizing plate 7 contacts the surface of the movable smoke barrier 4, so that the movable smoke barrier 4 can be cleaned.

[0025] The surface of the mounting seat 2 is provided with mounting holes for convenient bolt fixing.

[0026] When it is necessary to block the smoke, the motor 50 is turned on and the output shaft of the motor 50 rotates, driving the movable plate 552 to rotate. At this time, the surface of the movable plate 552 contacts the surface of the contact plate 551, thereby causing the bevel gear 1 52 to rotate, and then driving the bevel gear 2 53 to rotate, causing the threaded rod 54 to rotate. At this time, the slide plate 8 and the movable smoke barrier wall 4 move down for adjustment, and no manual adjustment is required, thereby increasing its efficiency. The heat dissipation holes 3 are set, so that the heat generated by the motor 50 can be discharged. At the same time, when the movable smoke barrier wall 4 moves, the brush can clean its surface. When the movable smoke barrier wall 4 is not needed, the motor 50 is turned on and reversed, and the threaded rod 54 is reversed to retract the movable smoke barrier wall 4. When the top of the slide plate 8 contacts the fixed plate 51, if the personnel do not turn off the motor 50 in time, the flipping of the movable plate 552 will not affect the normal operation of the motor 50, thereby preventing the motor 50 from being damaged.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
