DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a connection device for assembled curtain wall construction includes a first mounting block 1 and a second mounting block 2, wherein the first mounting block 1 is fixedly mounted on the wall by expansion bolts, and the second mounting block 2 is fixedly mounted on the curtain wall by bolts, an L-shaped clamping block 3 is fixedly mounted on one side of the second mounting block 2, an L-shaped clamping groove 4 for accommodating the L-shaped clamping block 3 is provided in the middle of one side of the first mounting block 1, a positioning plate 5 is rotatably mounted on the middle of the top end of the first mounting block 1 by an axle pin, and the lower surface of the positioning plate 5 after rotation can be arranged to fit with the top of the L-shaped clamping block 3, so as to fix the position of the L-shaped clamping block 3.

[0022] like Figures 1 to 4 As shown, the end of the L-shaped clamping block 3 away from the second mounting block 2 is provided with a chamfer 6 .

[0023] It is convenient to slide the L-shaped card block 3 into the L-shaped card slot 4.

[0024] like Figures 1 to 4 As shown, the top of the positioning plate 5 is symmetrically provided with sliding holes 7, and a positioning rod 8 is slidably installed inside the sliding hole 7. An extrusion spring 9 is fixedly installed at one end of the positioning rod 8. The end of the extrusion spring 9 away from the positioning rod 8 is fixedly connected to the end of the sliding hole 7 corresponding to the positioning plate 5. The end of the positioning rod 8 away from the extrusion spring 9 is provided with a rounded corner 10. The middle part of the first mounting block 1 is provided with an inclined surface 11 corresponding to the position on both sides of the positioning plate 5. The positioning rod 8 and the inclined surface 11 are extruded. A positioning hole 12 is provided at the middle part of the first mounting block 1 at the end of the rotation trajectory of the positioning rod 8, and the positioning hole 12 is slidably connected to the positioning rod 8.

[0025] By rotating the positioning plate 5, the positioning rod 8 is squeezed on the inclined surface 11 to drive the positioning rod 8 to be stored in the sliding hole 7. At this time, the squeezing spring 9 is in a compressed state. When the positioning rod 8 moves to the positioning hole 12, the squeezing of the positioning rod 8 by the squeezing spring 9 will drive the positioning rod 8 to slide into the positioning hole 12 to fix the position of the positioning plate 5. At this time, the lower surface of the positioning plate 5 is fitted with the top of the L-shaped block 3 to fix the position of the L-shaped block 3, thereby achieving fixation of the position of the curtain wall.

[0026] like Figures 1 to 4 As shown, the positioning hole 12 and the positioning rod 8 are tightly fitted and slidable.

[0027] The position of the positioning plate 5 is ensured to be fixed, and the positioning plate 5 is prevented from swinging, thereby achieving the stability of the curtain wall position.

[0028] like Figures 1 to 4 As shown, a mounting groove 13 is provided in the middle of the positioning plate 5, and a moving block 14 is slidably installed inside the mounting groove 13, and fixing rods 15 are symmetrically fixedly installed at both ends of the moving block 14. A track groove 16 for sliding the fixing rod 15 is provided at the top of the first mounting block 1, and a semicircular groove 17 for accommodating the fixing rod 15 is provided at the top of the first mounting block 1 corresponding to the end position of the fixing rod 15, and the semicircular groove 17 is connected to the track groove 16, and a pulling spring 18 is symmetrically fixedly installed on the lower surface of the moving block 14, and the end of the pulling spring 18 away from the moving block 14 is fixedly connected to the bottom of the mounting groove 13 corresponding to the positioning plate 5.

[0029] When the first mounting block 1 is fixed on the wall, the pulling of the moving block 14 by the pulling spring 18 will drive the fixing rod 15 to be stuck in the semicircular groove 17, which is used to fix the position of the positioning plate 5. When the positioning plate 5 is rotated, the fixing rod 15 will also rotate. At this time, the fixing rod 15 will slide out of the semicircular groove 17, canceling the positioning of the positioning plate 5.

[0030] like Figures 1 to 4As shown, a push rod 19 is slidably installed inside the positioning hole 12, and a return spring 20 is sleeved on the outer side of the push rod 19. One end of the return spring 20 is fixedly connected to one side of the first mounting block 1, and the other end of the return spring 20 is fixedly connected to one end of the push rod 19.

[0031] When the curtain wall needs to be removed for maintenance, the two push rods 19 are pressed to push the positioning rod 8 to slide out of the positioning hole 12, and the positioning plate 5 can be rotated to cancel the positioning of the L-shaped block 3 by the positioning plate 5, so that the curtain wall can be removed.

[0032] like Figures 1 to 4 As shown, the second mounting blocks 2 are mounted at the four corners of the curtain wall and are equidistantly mounted at the middle of the curtain wall.

[0033] It is used to stably install the curtain wall on the wall and improve the stability of the overall installation of the curtain wall.

[0034] The utility model provides a connection device for assembled curtain wall construction, and the specific working principle is as follows:

[0035] When the device is in use, a plurality of first mounting blocks 1 are fixed on the wall by measuring, a plurality of second mounting blocks 2 are fixedly installed on the assembled curtain wall by bolts in advance, the first mounting blocks 1 and the second mounting blocks 2 are arranged correspondingly, the curtain wall is first lifted by a crane and moved to the installation position, and then the curtain wall is lowered, and the L-shaped card block 3 on the second mounting block 2 is slid into the L-shaped card slot 4 on the first mounting block 1 for placing the curtain wall, and then another curtain wall can be lifted by a crane and moved to the next installation position, thereby improving the installation of the curtain wall. To improve the installation efficiency, after the curtain wall is placed, by rotating the positioning plate 5, the positioning rod 8 is squeezed on the inclined surface 11 to drive the positioning rod 8 to be stored in the sliding hole 7. At this time, the squeezing spring 9 is in a compressed state. When the positioning rod 8 moves to the positioning hole 12, the squeezing of the positioning rod 8 by the squeezing spring 9 will drive the positioning rod 8 to slide into the positioning hole 12 to fix the position of the positioning plate 5. At this time, the lower surface of the positioning plate 5 is fitted with the top of the L-shaped block 3 to fix the position of the L-shaped block 3, thereby fixing the position of the curtain wall.

[0036] 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.
