DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1

[0017] See also Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a fireproof rolling shutter bottom plate bidirectionally adjustable structure, including a bottom plate 1, a lower hanging piece 2, an upper hanging piece 3, a long screw 4, a limit adjustment nut 5 and a self-tapping screw 7, the bottom plate 1 is arranged directly below the bottom steel frame 6 of the fireproof rolling shutter, the bottom hanging pieces 2 are installed on both sides of the top of the bottom plate 1, and the upper hanging pieces 3 corresponding to the lower hanging pieces 2 are installed on both sides of the bottom steel frame 6 of the fireproof rolling shutter, and the upper hanging pieces 3 are installed by self-tapping screws. 7 is fixed on the side of the bottom steel frame 6 of the fireproof rolling shutter, and bolt holes corresponding to the long screw 4 are opened on the upper hanging member 3 and the lower hanging member 2, and the two ends of the long screw 4 are respectively penetrated into the inner side of the lower hanging member 2 and the upper hanging member 3, and the two end surfaces of the long screw 4 are sleeved with limit adjustment nuts 5, and the two limit adjustment nuts 5 are respectively tightly attached to the lower hanging member 2 and the upper hanging member 3 to realize the connection between the lower hanging member 2 and the upper hanging member 3, so that the bottom plate 1 can be installed below the bottom steel frame 6 of the fireproof rolling shutter through the two hanging members. Subsequently, the positions of the lower hanger 2 and the upper hanger 3 can be adjusted by rotating and twisting the long screw 4. When the positions of the lower hanger 2 and the upper hanger 3 change, the parallelism between the base plate 1 and the bottom steel frame 6 of the fireproof roller shutter changes, that is, the base plate 1 will tilt, and the parallelism of the base plate 1 can be adjusted in both directions. A high-elasticity buffer spring 9 is also sleeved on the surface of the long screw 4 relative to the lower hanger 2 and the upper hanger 3. The high-elasticity buffer spring 9 can protect the base plate 1. The high-elasticity buffer spring 9 reduces the impact on the base plate 1 by deformation, reduces the distortion of the base plate 1, improves the fire prevention effect, and facilitates the resetting of the fireproof roller shutter.

The rotating seat 83 is rotatably installed on the inner surface of the lower hanging part 2, and the surface of the rotating seat 83 is welded and fixed with the limit block 84. The surface of the connecting block 82 is provided with a rectangular card slot 85 corresponding to the limiting card block 84.

The inside of the connecting block 82 is provided with an inner groove 89 on one side relative to the rectangular card slot 85. A reset spring 810 and a telescopic card bead 811 are arranged in the inner groove 89.

The swivel seat 83 is first rotated upward to allow the limit block 84 to be rotated into the rectangular slot 85, and the end of the telescopic bead 811 is pushed by the return spring 810 to be inserted into the limit slot 812, thereby playing a role in locking and limiting the limit block 84, ensuring that the limit block 84 can be stably stuck in the rectangular slot 85 during daily use, ensuring the limiting stability of the connecting plug 82, and when assembling the bottom plate 1 and the lower hanging member 2, first rotate the rotating seat 83 upward to allow the limit block 84 to be rotated ... 84 does not block the insertion of the connecting block 82, and then the connecting block 82 is passed through the bottom plate 1 and the lower hanging member 2, so that the end of the connecting block 82 passes through the inner side of the lower hanging member 2 until the end block 81 is in contact with the side of the bottom plate 1, and then the rotating seat 83 and the limiting block 84 are rotated downward, so that the limiting block 84 can be screwed into the rectangular slot 85, so that the end of the telescopic bead 811 is pushed by the reset spring 810 to be inserted into the limiting slot 812, so that the limiting block 84 can be limited, ensuring the limiting stability of the limiting block 84 on the connecting block 82.

[0019] A shaft rod with a T-shaped cross section is fixed to the inner side of the lower hanging member 2 , and the rotating seat 83 is rotatably sleeved on the shaft rod, so that the rotating seat 83 can rotate smoothly.

[0020] Among them, one end of the return spring 810 is fixed on the inner wall of the inner groove 89, and the other end of the return spring 810 is fixed on the telescopic card bead 811 to achieve stable limiting of the return spring 810.

[0022] Example 2

[0023] See also Figures 1 to 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the L-shaped rubber seat 86, the positioning protrusion 87 and the positioning slot 88 can be provided to play an auxiliary positioning role when the connecting block 82 passes through the inner side of the lower hanging member 2.

[0024] Specifically, an L-shaped rubber seat 86 is glued and fixed to the inner side of the lower hanging member 2 relative to the bottom of the connecting block 82, and an integrated positioning protrusion 87 is provided on the top surface of the L-shaped rubber seat 86. Both are made of rubber material and will undergo elastic deformation when squeezed. A positioning groove 88 corresponding to the positioning protrusion 87 is provided on the surface of the connecting block 82, and the positioning protrusion 87 is embedded in the positioning groove 88, so that after the connecting block 82 passes through the inner side of the lower hanging member 2, the positioning protrusion 87 will also be squeezed into the positioning groove 88, thereby playing an auxiliary limiting role for the connecting block 82 and the end block 81, making it convenient for subsequent operators to screw the limiting block 84 into the rectangular groove 85.
