Referring to fig. 1 to 4, a flat screen window without a bottom rail comprises a first side post 1 and a second side post 2, the tops of the first side post 1 and the second side post 2 are connected through a fixed beam 3, a sliding beam 4 is slidably connected between the first side post 1 and the second side post 2, the top of the sliding beam 4 is detachably connected with a sliding seat 11, two sides of the bottom surface of the sliding seat 11 are respectively provided with a clamping strip 15 with an L-shaped cross section, a clamping groove 16 for clamping the sliding beam 4 is formed between the adjacent clamping strips 15, a plurality of bolts 17 are rotatably connected on the top surface of the sliding seat 11, a plurality of threaded holes 18 matched with the bolts 17 are formed on the top surface of the sliding beam 4, two sides of the bottom surface of the sliding seat 11 are respectively provided with a first inserting block 19, two sides of the sliding beam 4 are respectively provided with a slot 20 for clamping the first inserting block 19 in the length direction, a sliding block 12 with a T-shaped cross section is arranged on the top of the sliding seat 11, a sliding groove 13 for clamping the sliding block 12 is formed on the bottom surface of the fixed beam 3 in the length direction, the top side wall of the sliding block 12 is rotatably connected with a plurality of pulleys 14, the bottom end of the sliding beam 4 is detachably connected with a guide seat 5, a chain 6 is arranged between the guide seat 5 and the bottom end of the first side column 1, a first accommodating cavity 7 is formed in the guide seat 5, a guide piece for guiding the chain 6 is arranged in the first accommodating cavity 7, the guide piece comprises two guide rails 21 arranged on the inner walls of the two sides of the first accommodating cavity 7, a guide groove 22 is formed between the adjacent guide rails 21 on the same inner wall, the top ends of the guide rails 21 are upwards extended and clamped into the second accommodating cavity 8, two insertion blocks 23 for clamping into the insertion grooves 20 are arranged on the two sides of the top surface of the guide seat 5, the second accommodating cavity 8 for accommodating the chain 6 is formed inside the sliding beam 4, a fixing strip 9 for fixing a yarn net is arranged on one surface of the first side column 1 facing the sliding beam 4, and an installation cavity 10 for installing the yarn net is formed between the fixing strip 9 and the sliding beam 4.

Because the tops of the first side column 1 and the second side column 2 are connected through the fixed beam 3, and the sliding beam 4 is connected between the first side column 1 and the second side column 2 in a sliding manner, when the gauze is used, the gauze is fixedly installed in the installation cavity 10 through the fixed strip 9 on the side wall of the first side column 1, when the sliding beam 4 slides, the gauze can be unfolded and folded along with the fixed strip, meanwhile, because the chain 6 is arranged between the guide seat 5 and the bottom end of the first side column 1, the first accommodating cavity 7 is formed in the guide seat 5, the second accommodating cavity 8 is formed in the sliding beam 4, in the process of folding the gauze, one end of the chain 6 can enter the first accommodating cavity 7 and then enters the second accommodating cavity 8 through the guide piece until the gauze is completely folded, the space required by the chain 6 is not occupied, and further, when the flat screen window is installed, an installer does not need to manufacture a frame for accommodating the lower frame, and the operation is convenient.

Because the top of the sliding beam 4 is detachably connected with a sliding seat 11, the sliding seat 11 is provided with a sliding block 12 with a T-shaped cross section, the sliding block 12 is clamped into a sliding groove 13 and then slides along the length direction of the fixed beam 3, the sliding connection of the sliding beam 4 between the side column I1 and the side column II 2 is realized, and the sliding groove 13 is used for limiting the sliding block 12, so that the sliding beam 4 is not easy to fall out of the sliding groove 13 under the action of gravity, and the sliding process is more stable.

Because the side wall of the top of the sliding block 12 is rotatably connected with the plurality of pulleys 14, in the sliding process of the sliding block 12, the pulleys 14 can roll on the inner side wall of the sliding groove 13, so that the sliding friction between the sliding block 12 and the sliding groove 13 is converted into the rolling friction between the pulleys 14 and the sliding groove 13, the friction force is greatly reduced, and the sliding of the sliding block 12 is more stable and smooth.

Because the clamping strips 15 are arranged on two sides of the bottom surface of the sliding seat 11, the top of the sliding beam 4 is clamped into the clamping groove 16 surrounded by the clamping strips 15 with the L-shaped cross section, the sliding beam 4 can be clamped with the sliding seat 11, and because the top surface of the sliding seat 11 is rotatably connected with a plurality of bolts 17, after the sliding beam 4 is clamped into the clamping groove 16, the bolts 17 are rotated to be screwed into the threaded holes 18 on the top of the sliding beam 4, the sliding beam 4 and the sliding seat 11 are reinforced through the bolts 17, and the sliding seat 11 is connected on the sliding beam 4 more firmly.

Because the two sides of the bottom surface of the sliding seat 11 are provided with the first insertion blocks 19, after the sliding beam 4 is clamped into the clamping groove 16, the first insertion blocks 19 are clamped into the slots 20, the first insertion blocks 19 are limited by the slots 20, so that the sliding seat 11 is less prone to shaking, the bolts 17 can be more accurately aligned with the threaded holes 18, and the connection is more convenient.

Because the guide part comprises the guide rails 21, the guide groove 22 is formed between the two guide rails 21, after one end of the chain 6 enters the first accommodating cavity 7, the side wall of the chain can enter the guide groove 22, and the chain 6 can enter the second accommodating cavity 8 upwards along with the continuous folding of the gauze under the guiding action of the two guide rails 21, so that the guiding effect of the guide part is realized, and the space is saved.

Because the top end of the guide rail 21 extends upwards and is clamped into the second accommodating cavity 8, the top end of the guide rail 21 can be clamped into the second accommodating cavity 8, and the guide seat 5 can be easily arranged at the bottom of the sliding beam 4 through the limitation of the top end of the guide rail 21 on the sliding beam 4.

Because the two sides of the top surface of the guide seat 5 are provided with the second insertion block 23, in the process of clamping the top end of the guide rail 21 into the second accommodating cavity 8, the second insertion block 23 is clamped into the slot 20, and the second insertion block 23 is limited by the slot 20, so that the guide seat 5 is more stably installed at the bottom of the sliding beam 4.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
