DETAILED DESCRIPTION

[0027] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Embodiment 1

[0029] Figure 1-Figure 3 In one embodiment of the utility model, a strip brush height adjustment structure comprises a frame 1, the frame 1 comprises a U-shaped frame 101 at the bottom, and a side plate 102 at the top of the U-shaped frame 101, the U-shaped frame 101 and the side plate 102 are an integrated structure, the bottom of the U-shaped frame 101 is provided with a strip brush 2 extending into the inside thereof, and the top of the U-shaped frame 101 is installed with a height adjustment component 3, the strip brush 2 can be installed at the bottom of a rolling door, a high-speed train, a subway screen door, and a door and window. In this embodiment, the strip brush 2 is installed at the bottom of a subway screen door as an example, and the U-shaped frame 10 1 is attached to the bottom of the subway screen door, and the side plate 102 is attached to one side of the subway screen door. The distance between the U-shaped frame 101 and the bottom of the subway screen door is adjusted by the height adjustment component 3 until the strip brush 2 squeezes the subway ground and bends. The height of the strip brush 2 can be adjusted as needed, so that the strip brush 2 can contact the subway ground when the subway screen door is at different distances from the subway ground, so that the strip brush 2 can meet the requirements of sealing spaces at different heights. After the strip brush 2 is worn, the height of the strip brush 2 can be adjusted again to make the strip brush 2 contact the ground, so as to block dust after wear.

[0030] The height adjustment component 3 includes a longitudinal plate 1 31 and two longitudinal plates 2 32 installed on the top of the U-shaped frame 101. The tops of the longitudinal plates 1 31 and 32 are fixedly connected with arc plates 33 with horizontal tops. The heights of the longitudinal plates 1 31 and 32 increase as the distance between them and the side plates 102 increases. A clamping component 34 is installed on one side of the side plate 102. The longitudinal plates 1 31 and 32 are installed on the side close to the side plate 102 with multiple anti-sliding blocks. The clamping component 34 includes a bolt with one end movably penetrating the side plate 102. The end of the bolt close to the longitudinal plate 1 31 is provided with a pad. When in use, according to the subway screen door and the subway ground The distance between them is selected, and the top of the arc-shaped plates 33 of different heights is placed against the bottom of the subway screen door, the side plate 102 is on the left side of the subway screen door, and one of the longitudinal plates 1 31 and 32 is on the right side of the subway screen door, so that the strip brush 2 can contact the ground and be squeezed and bent by the ground, and then the bolt is turned, and the bolt pushes the pad to gradually approach the subway screen door until the subway screen door is squeezed on one of the longitudinal plates 1 31 and 32, completing the process of fixing the subway screen door to the frame 1. At this time, the strip brush 2 is installed at different distances from the bottom of the subway screen door, so as to meet the purpose of the strip brush 2 blocking dust at different distances.

[0031] The two longitudinal plates 32 are fixedly connected to one side close to the longitudinal plate 1 31 with multiple elastic arc plates 4, and the elastic arc plates 4 are fixedly connected to one end away from the longitudinal plate 2 32 with a semi-cylinder 5. The tops of the longitudinal plates 1 31 and the longitudinal plates 2 32 are provided with arc grooves adapted to the elastic arc plates 4. The frame 1 is installed at the bottom of the subway screen door. When the subway screen door is between the side plate 102 and the longitudinal plate 1 31, the subway screen door squeezes and bends the elastic arc plate 4 on the far left, and one side of the plane of the semi-cylinder 5 is squeezed onto the subway screen door by the elastic arc plate 4. The longitudinal plates 1 31 and the longitudinal plates 2 32 limit the position of the subway screen door, and the fixed positions of the frame 1 and the strip brush 2 and the subway screen door are increased. Fixing from multiple locations increases the firmness of the installation of the strip brush 2. When the right side of the subway screen door abuts against the longitudinal plate 2 32, the subway screen door squeezes and bends the elastic arc plate 4 below it downwards to Figure 2 For example, the arc surface on the right side of the semi-cylinder 5 enables it to slide along the arc groove to below the arc plate 33 when it is pressed downward, and will not hinder the bottom of the subway screen door from contacting the longitudinal plate 1 31 and the longitudinal plate 2 32.

[0032] The strip brush 2 is slidably connected to the inner wall of the U-shaped frame 101, and blocks 6 are installed on both sides of the inner wall of the U-shaped frame 101 to prevent the strip brush 2 from sliding out of the U-shaped frame 101. An elastic plate 7 is fixedly connected between the top of the strip brush 2 and the inner wall of the U-shaped frame 101, and the elastic plate 7 pushes the strip brush 2 to descend until the strip brush 2 is squeezed and bent after contacting the ground. When the strip brush 2 is worn out due to long-term use, the degree of squeezing and bending of the strip brush 2 decreases. At this time, the elastic plate 7 pushes the strip brush 2 to continue to descend until the strip brush 2 is squeezed and bent after contacting the ground again. It can automatically push the strip brush 2 to descend after the strip brush 2 is worn out, thereby ensuring the contact between the strip brush 2 and the ground and preventing dust from passing through the strip brush 2 from the bottom of the strip brush 2.

[0033] Embodiment 2

[0034] Reference Figure 1-Figure 5 On the basis of the first embodiment, a plurality of air vents are provided on one side of the side panel 102, and an opening corresponding to the air vent is provided on the top of the U-shaped frame 101, and a push plate 8 is installed inside the air vent. When the subway screen door is opened or closed, the subway screen door drives the frame 1 and the strip brush 2 to move, and the push plate 8 moves with the frame 1, driving the surrounding air to move laterally. The flowing air is blocked by the subway screen door after passing through the air vent, and then enters the U-shaped frame 101 through the opening, which can increase the air flow speed around the strip brush 2, blow off the dust attached to the surface of the strip brush 2, and prevent the dust from adhering to the strip brush 2 and causing secondary pollution to the subway.

[0035] A round block 9 is installed at the bottom inner side of the air vent, and a plurality of longitudinal grooves connected in the middle are opened on the top of the round block 9. The push plate 8 movably extends into one of the longitudinal grooves. The bottom of the round block 9 is rotatably connected with a bottom block 10. The bottom of the bottom block 10 is provided with a threaded rod 11 movably extending to the inside of the side plate 102. The outside of the bottom block 10 is fixedly connected with a plurality of protrusions 12. When in use, the protrusions 12 are pushed to drive the bottom block 10 and the threaded rod 11 to rotate until the bottom block 10 and the round block 9 drop to the lowest point, and then the push plate 8 is placed in one of the longitudinal grooves on the round block 9, and then the protrusion 12 is rotated in the opposite direction to drive the bottom block 10 and the threaded rod 11 to rotate and rise, thereby pushing the round block 9 and the push plate 8 above it to rise until the top of the push plate 8 is close to the inner top of the air vent. The angle of the push plate 8 can be adjusted as needed to control the air flow in different directions, so as to achieve the purpose of blowing away the dust attached to the surface of the strip brush 2 from different angles.
