Detailed implementation manners

[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0020] See Figures 1 to 11As shown, an anti-falling device for an assembled building curtain wall 2 comprises a wall body 1, a curtain wall 2, an anti-falling mechanism 3 and a locking mechanism 4; a plurality of brackets 11 are arranged on the wall body 1, a plurality of rectangular fixing tubes 12 are arranged equidistantly on the brackets 11, the opening direction of the rectangular fixing tubes 12 faces the side away from the wall body 1, each outer wall of the rectangular fixing tubes 12 is provided with a strip-shaped through groove 121, a plurality of directional strips 21 corresponding to the rectangular fixing tubes 12 are arranged on the curtain wall 2, and a resisting plate 13 contacting the directional strip 21 is slidably arranged inside each rectangular fixing tube 12; the anti-falling mechanism 3 is arranged inside the corresponding rectangular fixing tube 12 and is used to lock the fixing strip The four plug plates 31 can be moved toward the inside of the rectangular fixed tube 12 synchronously with the movement of the corresponding contact plate 13. A rectangular groove 311 is provided at one end of each plug plate 31 extending into the corresponding rectangular fixed tube 12. A plug block 32 that can move with the movement of the contact plate 13 is slidably provided in each rectangular groove 311. A slot 211 cooperating with the plug block 32 is provided on each outer wall of the directional strip 21. The locking mechanism 4 is provided at the bottom of the rectangular fixed tube 12 and is used to fix the position of the contact plate 13.

[0021] The staff makes the directional strips 21 on the curtain wall 2 correspond to the rectangular fixed tubes 12 at the corresponding positions on the wall 1 one by one, so that the directional strips 21 can be inserted into the corresponding rectangular fixed tubes 12. At this time, the directional strips 21 contact the abutment plates 13 on the inner wall of the corresponding rectangular fixed tubes 12, thereby pushing the abutment plates 13 to move. With the movement of the abutment plates 13, the plug plates 31 slidingly arranged in the strip-shaped through grooves 121 can synchronously move toward the direction close to the directional strips 21, and the four plug plates 31 can abut against the side walls of the corresponding directional strips 21, thereby abutting the directional strips 21. It is fixed in the center to prevent it from shaking, thereby preventing the curtain wall 2 from shaking in the vertical plane; and in this process, the plug block 32 set in the rectangular groove 311 can move with the movement of the contact plate 13, thereby extending into the slot 211 of the directional strip 21, preventing the fixing strip from falling off from the rectangular fixing tube 12, thereby further fixing the curtain wall 2; then, the contact plate 13 is fixed by the locking mechanism 4 set at the bottom of the rectangular fixing tube 12, so that the four plug plates 31 that cooperate with the contact plate 13 are fixed, so that the curtain wall 2 is in a stable state. When maintenance and replacement are required, the contact plate 13 can be moved by contacting the locking mechanism 4, and the plug plate 31 and the plug block 32 can be separated from the corresponding positioning strip through the movement of the contact plate 13, so that it is convenient for the staff to maintain and replace the curtain wall 2.

[0022] See also Figures 5 to 9As shown, the anti-slip mechanism 3 also includes a horizontal plate 33 and a downward pressing rod 34; an extension strip 131 is provided at the center of each side of the side of the inner wall of the bottom of the rectangular fixed cylinder 12 on the side of the contact plate 13 away from the rectangular fixed cylinder 12, and each plug plate 31 is provided with a strip-shaped notch 312 for avoiding the extension strip 131, and one end of each extension strip 131 away from the contact plate 13 passes through the plug plate 31 through the corresponding strip-shaped notch 312 and is provided with two right-angled trapezoidal guide blocks 132, and the inclined surface of the right-angled trapezoidal guide block 132 faces the direction of the corresponding contact plate 13; the bottom of the strip-shaped notch 312 is provided with an arc-shaped guide surface 313 that cooperates with the right-angled trapezoidal guide block 132; The flat plate 33 is slidably set in the corresponding rectangular groove 311, and the horizontal plate 33 and the corresponding plug block 32 are connected to each other through a downward pressure spring. The bottom inner wall of the rectangular groove 311 is provided with a guide hole 314 connected to the strip-shaped groove 312, and a downward pressure rod 34 is provided at the top center of the horizontal plate 33. The end of the downward pressure rod 34 extending into the strip-shaped groove 312 through the guide hole 314 is provided with an arc-shaped resistance block 341, and the end of the extension bar 131 away from the corresponding resistance plate 13 is provided with an arc-shaped downward pressure block 133 for cooperating with the arc-shaped resistance block 341, and the arc-shaped downward pressure block 133 is located between the two right-angled trapezoidal guide blocks 132.

[0023] When the directional strip 21 is inserted into the rectangular fixed tube 12, the directional strip 21 is located between the four extension plates. As the directional strip 21 contacts the corresponding abutment plate 13, the abutment plate 13 drives the corresponding extension strip 131 to move. The right-angled trapezoidal guide block 132 at the end of the extension strip 131 can contact the arc-shaped guide surface 313 on the corresponding strip-shaped notch 312. The arc-shaped guide surface 313 can move along the inclined surface of the right-angled trapezoidal guide block 132, thereby pushing the plug plate 31 to move toward the direction close to the directional strip 21, so that the plug plate 31 can abut against the directional strip 21. The outer wall of the directional strip 21 is touched, thereby achieving the preliminary fixation of the directional strip 21, and as the resistance plate 13 continues to move, the arc-shaped resistance block 341 on the pressure rod 34 can contact the arc-shaped pressure block 133 on the extension strip 131, so that the horizontal plate 33 can move toward the direction close to the plug block 32, thereby compressing the pressure spring, and when the plug block 32 moves to the slot 211 of the directional strip 21, the plug block 32 can be inserted into the slot 211, thereby performing secondary fixation on the directional strip 21, further ensuring the stability of the curtain wall 2.

[0024] See also Figure 2 and Figure 5 As shown, a plurality of fixed frames 22 are also provided on the curtain wall 2, and the directional strips 21 are located inside the corresponding fixed frames 22. An L-shaped clip 315 is provided at one end of each plug plate 31 away from the inside of the rectangular fixed tube 12, and an annular clip 23 cooperating with the L-shaped limit piece is provided at one end of each fixed frame 22 away from the current one.

[0025] As the plug board 31 moves, the L-shaped clamping member 315 provided at the end of the plug board 31 can move towards the direction close to the fixed frame 22, and the annular clamping plate 23 provided at the end of the fixed frame 22 can extend into the space between the L-shaped clamping member 315 and the plug board 31, thereby realizing the secondary fixation of the curtain wall 2 and further ensuring the stability of the curtain wall 2.

[0026] See Figures 5 to 9 As shown, a first return spring 342 is also sleeved on each pressing rod 34. The first return spring 342 is located between the arc-shaped abutting block 341 and the corresponding arc-shaped guiding surface 313. A connecting plate 316 is also provided on each plug board 31, and a second return spring 317 is provided on the connecting plate 316. The second return spring 317 is located between the corresponding connecting plate 316 and the outer wall of the rectangular fixed cylinder 12.

[0027] When disassembling and repairing the curtain wall 2, by moving the abutting plate 13, the right-angled trapezoidal guiding block 132 is separated from the arc-shaped guiding surface 313. At this time, under the elastic force of the second return spring 317, the plug board 31 can be reset. During this process, the arc-shaped abutting block 341 is separated from the arc-shaped pressing block 133. Under the elastic force of the first return spring 342, the plug 32 can be retracted into the rectangular groove 311 to ensure that the curtain wall 2 can be removed, facilitating the staff to carry out maintenance and replacement.

[0028] See Figure 1 、 Fig.10 and Fig.11 As shown, the locking mechanism 4 includes a U-shaped plate 41 and a pressing shaft 42; a rectangular through groove 122 is provided at the center of the inner wall of the bottom of each rectangular fixed cylinder 12, and a connecting strip 134 is provided at the center of one side of each abutting plate 13 close to the corresponding rectangular through groove 122. There are two U-shaped plates 41, and the two U-shaped plates 41 are arranged mirror-symmetrically inside the rectangular through groove 122. The opening directions of the two U-shaped frames both face the center of the rectangular through groove 122. A pressing shaft 42 is rotatably provided inside each U-shaped plate 41. Return torsion springs 421 are sleeved on both ends of the pressing shaft 42, and a triangular limiting block 422 is provided at the center of the pressing shaft 42. A plurality of triangular notches 135 that cooperate with the triangular limiting block 422 are equidistantly arranged on both sides along the length direction of each connecting strip 134. Two extension rods 411 are provided on one side of each U-shaped plate 41 away from the corresponding pressing shaft 42. Orientation holes 123 for accommodating the extension rods 411 are provided on both inner walls of the rectangular through groove 122, and the extension rods 411 are slidably arranged in the corresponding orientation holes 123. A pushing spring 412 is sleeved on each extension rod 411.

[0029] Under the action of the elastic force of the pushing spring 412, both U-shaped plates 41 can move towards the connecting strip 134, so that the triangular limit blocks 422 arranged in the U-shaped plates 41 can be inserted into the corresponding triangular notches 135. At this time, the inclined surfaces of the triangular limit blocks 422 correspond to the inclined surfaces of the triangular notches 135 (the shape of the triangular limit blocks 422 is preferably a right triangle). When the guiding strip 21 pushes the抵触 plate 13 to move, the triangular limit blocks 422 can rotate against the torsion of the return torsion spring 421, thus avoiding affecting the movement of the抵触 plate 13. When the抵触 plate 13 moves to the corresponding position, the triangular limit blocks 422 can be inserted into the corresponding triangular notches 135, thereby fixing the抵触 plate 13; when unlocking is required, by separating the two U-shaped plates 41 from each other, the triangular limit blocks 422 can be separated from the corresponding triangular notches 135, and the抵触 plate 13 can be in a movable state, and the curtain wall 2 can be removed.

[0030] See Fig.11 As shown, an intercepting plate 413 for restricting the position of the triangular limit block 422 is further arranged on each U-shaped plate 41.

[0031] Relying only on the return torsion spring 421 may not be able to ensure that the抵触 plate 13 is in a locked state; thus, by arranging the intercepting plate 413 on the U-shaped plate 41, the triangular limit block 422 can contact the intercepting plate 413, so that the triangular limit block 422 can only rotate when the抵触 plate 13 moves towards the rectangular through slot 122, further ensuring the stability of the curtain wall 2.

[0032] See Figure 2 As shown, the guiding strips 21 on the curtain wall 2 are distributed in a matrix and correspond to the rectangular fixed cylinders 12 one by one.

[0033] Through the guiding strips 21 distributed in a matrix on the curtain wall 2, the curtain wall 2 can be fixed at multiple points, further ensuring the stability of the curtain wall 2 and preventing it from falling.

[0034] See Fig.11 As shown, a拨动板 414 is further arranged on each U-shaped plate 41.

[0035] By arranging the拨动板 414, it is convenient for the staff to adjust the position of the U-shaped plate 41.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
