DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1

[0025] A curtain wall bottom end is connected to a water-proof structure, such as Figure 1-Figure 4 As shown, it includes a curtain wall panel 1, a support frame 11, a rain shield block 2, a bracket 21, a motor 22, a screw rod 23, a guide rod 24, a push frame 25, a compression spring 26 and a clamping block 27. The front side of the support frame 11 is connected to the upper and lower curtain wall panels 1, and the left side of the support frame 11 is connected to the bracket 21. The motor 22 is installed on the bracket 21. The output shaft of the motor 22 is connected to the screw rod 23. The push frame 25 is slidably connected to the screw rod 23. The mating surface of the push frame 25 and the screw rod 23 is provided with a thread, which can drive the push frame 25 on the screw rod 23 when the screw rod 23 rotates. Sliding, the front side of the push frame 25 is connected to a rain shield block 2, and the rain shield block 2 is used to fill the gap between the curtain wall panels 1. Guide rods 24 are connected between the two sides of the bracket 21 and the rain shield block 2. The guide rods 24 are used to guide the push frame 25. The push frame 25 slides on the guide rods 24. The top and bottom of the rain shield block 2 are slidably connected with a clamping block 27. The top and bottom of the rain shield block 2 are provided with a plurality of compression springs 26. The two ends of the compression spring 26 are respectively connected to the rain shield block 2 and the clamping block 27. The compression spring 26 can push the clamping block 27 to make the clamping block 27 close to the curtain wall panel 1.

[0026] When it is necessary to fill the gap between the curtain wall panels 1, the motor 22 is started to drive the screw rod 23 to rotate. Under the guidance of the guide rod 24, the push frame 25 can slide along the screw rod 23, thereby pushing the rain shield block 2 into the gap of the curtain wall panel 1. The curtain wall panel 1 will squeeze the clamping block 27, so that the clamping block 27 is pushed into the rain shield block 2. At this time, the compression spring 26 is in a compressed state, and the compression spring 26 can push the clamping block 27 to fit tightly with the curtain wall panel 1.

[0027] like Figure 5 and Figure 6As shown, it also includes an airbag 3, an air cylinder 31, a first spring 32 and an air pipe 33. The pressing block 27 is installed with the airbag 3, and the airbag 3 is used to fill small gaps. The front side of the bracket 21 is connected to the air cylinder 31, and the first spring 32 is sleeved on the piston rod of the air cylinder 31. The two ends of the first spring 32 are respectively connected to the cylinder body of the air cylinder 31 and the piston rod of the air cylinder 31. The first spring 32 is used to reset the piston rod of the air cylinder 31. The cylinder body of the air cylinder 31 and the airbag 3 are connected with an air pipe 33. The air pipe 33 is a hose and can be deformed.

[0028] In order to prevent a small gap between the clamping block 27 and the curtain wall panel 1, when the push frame 25 moves forward, the push frame 25 can squeeze the piston rod of the air cylinder 31, the first spring 32 is compressed, and the air in the air cylinder 31 is injected into the airbag 3 through the air pipe 33, thereby expanding the airbag 3. The expanded airbag 3 can make the clamping block 27 and the curtain wall panel 1 more sealed. When the push frame 25 moves forward and resets, the first spring 32 is reset from the compressed state, thereby driving the piston rod of the air cylinder 31 to reset. At this time, the air in the airbag 3 is re-sucked into the air cylinder 31.

[0029] Example 2

[0030] On the basis of Example 1, Figure 7 and Figure 8 As shown, it also includes a slider 4, a pull rope 41, a second spring 42, a block 43 and a clamping rod 44. The slider 4 is slidably connected to the front side of the left part of the rain shield block 2, and the block 43 is slidably connected to the left side of the rain shield block 2. The block 43 is provided with an inclined surface for easy sliding. The right side of the rain shield block 2 is fixedly connected to the clamping rod 44, and a groove is provided on the clamping rod 44. The clamping block 43 fits with the groove of the clamping rod 44. The clamping rod 44 can squeeze the inclined surface of the block 43 so that the block 43 is squeezed. A pull rope 41 is connected between the slider 4 and the block 43. The second spring 42 is sleeved on the pull rope 41. The two ends of the second spring 42 are respectively connected to the rain shield block 2 and the block 43. The second spring 42 can clamp the block 43 in the clamping rod 44 and is also used for resetting the block 43.

[0031] When connecting multiple curtain wall panels 1, the clamping rod 44 is extended into the rain shield block 2 of another curtain wall panel 1, and the clamping rod 44 can squeeze the clamping block 43 to move the clamping block 43 forward. The second spring 42 is compressed, and after the groove of the clamping rod 44 moves to the front of the clamping block 43, the second spring 42 is reset from the compressed state, so that the clamping block 43 is clamped into the groove of the clamping rod 44, thereby fixing the clamping rod 44. When the connection needs to be released, just push the slider 4 to the right, and the slider 4 pulls the clamping block 43 through the pull rope 41 to pull the clamping block 43 out of the clamping rod 44. At this time, the clamping rod 44 can be detached from the rain shield block 2.

[0032] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
