DETAILED DESCRIPTION

[0020] Embodiment 1, as Figures 1 to 6 As shown, an open unit curtain wall system comprises a unit steel beam 1 installed on a wall surface, a unit curtain wall body 2 is arranged in the unit steel beam 1, symmetrically arranged receiving grooves are provided on the upper and lower inner walls of the unit steel beam 1, a positioning block 3 is installed in the receiving groove by bolts, a first slide groove 301 is provided through the top of the positioning block 3, and the cross-sectional shape of the first slide groove 301 is set to be V-shaped with both ends closed; a circular plate 4 is provided at the bottom of the positioning block 3, the circular plate 4 is rotatably connected in the receiving groove, a second slide groove 401 is provided through the top of the circular plate 4, one end of the second slide groove 401 has a large diameter and the other end has a small diameter; a first telescopic rod 5 is fixedly connected to the top of the circular plate 4, and the end of the first telescopic rod 5 contacts the bottom of the positioning block 3; and a third telescopic rod 7 is fixedly connected to both ends of the unit curtain wall body 2.

[0021] In this embodiment, a reserved hole is opened in advance on the facade wall, and a connecting piece is installed in the reserved hole to fix the unit steel beam 1. After the unit steel beam 1 is fixed, the unit curtain wall body 2 is pushed in the direction of the unit steel beam 1 in sequence. Two third telescopic rods 7 are symmetrically distributed on both sides of the unit curtain wall body 2. Further, the third telescopic rod 7 is connected by two slidingly connected guide rods through a first spring, wherein the end of the guide rod away from the unit curtain wall body 2 is fixedly connected with a circular protrusion, and the circular protrusion is squeezed by the side wall of the unit steel beam 1 to overcome the force of the first spring and shrink until the circular protrusion reaches the position of the accommodating groove, and the diameter of the circular protrusion is smaller than the end with the largest diameter of the second slide groove 401, and the diameter of the circular protrusion is smaller than the end with the largest diameter of the first slide groove 301 in a V shape. Further, under the action of the first spring, the circular protrusion passes through the end with a larger diameter of the first slide groove 301 and the end with a larger diameter of the second slide groove 401 in sequence to perform preliminary and rapid positioning of the unit curtain wall body 2; After the unit curtain wall body 2 is initially positioned, the unit curtain wall body 2 continues to be pushed to move in the direction of the unit steel beam 1. At this time, the third telescopic rod 7 slides along the closed V-shaped first sliding groove 301, so that the third telescopic rod 7 slides from the end with a larger diameter of the first sliding groove 301 to the end with a smaller diameter, making the third telescopic rod 7 tighter and tighter. At the same time, there is a gap between the circular disk 4 and the bottom end of the accommodating groove. While the third telescopic rod 7 slides along the first sliding groove 301, it can slide along the inside of the second sliding groove 401, and also slide from the end with a larger diameter of the second sliding groove 401 to the end with a smaller diameter. While the third telescopic rod 7 slides inside the second sliding groove 401, it can drive the circular disk 4 to rotate 30 degrees counterclockwise. The rotation of the circular disk 4 drives the first telescopic rod 5 to rotate. When the third telescopic rod 7 moves to the end with the smallest diameter of the first sliding groove 301 and the second sliding groove 401, the first telescopic rod 5 just rotates to the position of the first sliding groove 301 to extend, thereby fixing the third telescopic rod 7.

[0022] like Figure 7 As shown, as the specific structure of this embodiment, the first telescopic rod 5 includes a second rod 502, a cavity is opened at the top of the second rod 502, a first rod 501 is slidably connected in the cavity, and the first rod 501 and the second rod 502 are connected by a second spring 503; an unlocking component is arranged in the cavity.

[0023] In this embodiment, when the circular plate 4 rotates 30 degrees counterclockwise to drive the first telescopic rod 5 to rotate counterclockwise to the position of the first sliding groove 301, the first rod 501 is lifted upward by the force of the second spring 503 to block and limit the third telescopic rod 7.

[0024] like Figure 6As shown, as a further solution of the present invention, the bottom of the circular disk 4 is provided with a plurality of second telescopic rods 6 distributed in an annular manner, and the second telescopic rods 6 are all fixedly connected to the accommodating grooves; the top of the circular disk 4 is provided with a plurality of positioning holes 402 distributed in an annular manner, and the positioning holes 402 are distributed adjacent to the second telescopic rods 6; two groups of pin holes 8 are symmetrically distributed at both ends of the unit curtain wall body 2, and the number of pin holes 8 in each group corresponds to the number of positioning holes 402.

[0025] In this embodiment, when the circular disk 4 rotates 30 degrees counterclockwise, the positioning hole 402 can rotate 30 degrees counterclockwise along with the circular disk 4, so that the second telescopic rod 6 is aligned with the positioning hole 402. The internal structure of the second telescopic rod 6 is the same as that of the first telescopic rod 5, so that the second telescopic rod 6 is extended and passes through the positioning hole 402 in sequence and is inserted into the latch hole 8. The extension of the second telescopic rod 6 not only further fixes the circular disk 4, but also further fixes the unit curtain wall body 2, thereby improving the stability of the fixation of the unit curtain wall body 2.

[0026] Embodiment 2, as Figures 7 to 9 As shown, as a further solution of the present invention: the unlocking component includes a vertical block 507, the vertical block 507 is fixedly connected to the inner bottom end of the second rod 502, a third slide groove 508 is penetrated through the vertical block 507, a second slide bar 506 is slidably connected in the third slide groove 508, an iron block 505 is fixedly connected to the outer side of the second slide bar 506, a first slide bar 504 is fixedly connected to the top of the iron block 505, and the first slide bar 504 is slidably connected to the bottom of the first rod 501.

[0027] In this embodiment, since the position of the second telescopic rod 6 remains unchanged, the initial position of the unlocking component inside the second telescopic rod 6 is maintained at 0 degrees along the Y axis, that is, it is vertically arranged with the unit curtain wall body 2, and the initial position of the unlocking component inside the first telescopic rod 5 is in the negative 30 degree direction. After the first telescopic rod 5 rotates 30 degrees counterclockwise along the Y axis following the circular plate 4, the direction of the iron block 505 inside the first telescopic rod 5 is also 0 degrees of the Y axis. Similarly, an unlocking component is also arranged inside the third telescopic rod 7, and the initial position of the unlocking component is 0 degrees of the Y axis. Once the unit curtain wall body 2 is damaged and needs to be replaced, an external magnet can be installed and placed at a position of the unit steel beam 1 close to the iron block 505. At this time, the iron block 505 moves in the direction of the magnet under the adsorption of the magnet. The movement of the iron block 505 drives the second sliding rod 506 to slide along the inside of the third sliding groove 508, and then the iron block 505 pulls the first rod 501 to overcome the force of the second spring 503 and retract toward the second rod 502. At the same time, the second telescopic rod 6 can be retracted according to the same working principle. At this time, the unit curtain wall body 2 can be sucked by the suction cup and moved in the direction away from the unit steel beam 1 until the third telescopic rod 7 slides along the first sliding groove 301 and the second sliding groove 401 to the end with the largest diameter. At this time, the third telescopic rod 7 retracts under the action of the external magnet, and the unit curtain wall body 2 is completely removed.

[0028] Furthermore, a reset assembly is provided at the bottom of the circular disk 4, and the reset assembly includes a sleeve 9, which is fixedly connected to the bottom of the circular disk 4, and a limiting rod 10 is fixedly connected to the inner bottom end of the accommodating groove, and the sleeve 9 and the limiting rod 10 are connected by a torsion spring.

[0029] In this embodiment, the circular disk 4 rotates 30 degrees counterclockwise to drive the sleeve 9 to rotate to overcome the force of the torsion spring. After the unit curtain wall body 2 is taken out, the circular disk 4 remains in place under the force of the torsion spring.

[0030] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
