[0022] As Figures 1-3 shown, a windproof device for the lower cross beam applicable to a door body includes: a bottom beam 1, the bottom of the bottom beam 1 is hollowly arranged, and an installation block 2 is fixedly connected inside the bottom beam 1. A round rod 3 is fixedly connected to the installation block 2, and moving wheels 4 are rotatably connected to both ends of the round rod 3. By respectively installing the two moving wheels 4 on both sides of the round rod 3 and inside the bottom beam 1, the function of moving the door body is realized.

[0023] A guiding mechanism is arranged inside the bottom beam 1 for clamping on the ground rail; the guiding mechanism includes: a fixing block 5, a through hole 6, an internal hexagonal bolt 7, a fixing rod 8, and a guiding wheel 9. The fixing block 5 is fixedly connected to the inner wall of the bottom beam 1. The number of through holes 6 is four, and they are symmetrically arranged in pairs on both sides of the central axis of the bottom beam 1. There are two fixing rods 8, which are inserted into the fixing block 5, and the top thereof contacts the top of the inner wall of the bottom beam 1. There are four internal hexagonal bolts 7, which respectively thread through the through holes 6 and contact the fixing rods 8. The guiding wheel 9 is installed on the outer wall of the fixing rod 8. By directly inserting the fixing rod 8 into the fixing block 5 and locking it in the through hole 6 through an external internal hexagonal bolt 7, and one end of the internal hexagonal bolt 7 abuts against the fixing rod 8, the function of fixing the fixing rod 8 is realized, so that the fixing rod 8 with the guiding wheel 9 can be conveniently installed on the fixing block 5 to achieve the purpose of moving on the guide rail.

[0024] The number of guiding wheels 9 is two, and they are respectively rotatably connected to the outer wall of the fixing rod 8, and the outer wall of the guide rail is clamped by the two guiding wheels 9. <>

[0025] The number of fixing blocks 5 is two, and the fixing blocks 5 are T-shaped and longitudinally and parallelly welded to the inner wall of the bottom beam 1.

Gate-shaped holes 11 are provided on both sides of the bottom beam 1 for mounting the moving wheels 4. By providing the rectangular through holes, the moving wheels can be accommodated, so as to internally accommodate the moving wheels 4 and reduce the height of the bottom beam 1. At the same time, the protective sleeve 12 provided can block the moving wheels 4 exposed from the rectangular through holes. At the same time, the gate-shaped holes 11 provided can be used to mount the moving wheels 4.

[0028] When the lower crossbeam windproof device of the door body is in use, the bottom beam 1 is mounted in the bottom profile of the door body through bolts and the four mounting holes, and then the two fixing rods 8 are inserted into both sides of the two fixing blocks 5 and locked by four hexagon socket head cap screws 7. At the same time, the two guide wheels 9 are clamped into the guide rail to achieve locking and movement.
