[0034] Example

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic structural diagram of an integrated rolling door device 100 provided in this embodiment. Figure 2 Shown is an exploded schematic diagram of the integrated rolling door device 100 .

[0036] The integrated rolling door device 100 provided in this embodiment includes a box body 110 and a rolling shutter assembly 120. The rolling shutter assembly 120 is arranged in the box body 110. A winding and unwinding channel 111 is provided at the bottom of the box body 110 for the rolling shutter assembly 120 to roll up and unroll the door curtain. An assembly groove 112 is provided at the top of the box body 110, and the assembly groove 112 is used to cooperate with the car frame of the fire truck.

[0037] It is understandable that when the integrated rolling shutter device provided in this embodiment is applied to a fire truck, it only needs to be matched with the fire truck's car frame through the assembly groove 112 opened on the top of the box body 110, and the structure of the car does not need to be changed. That is, the rolling shutter assembly 120 is installed in its own shell and does not occupy additional space in the car. And when the rolling shutter assembly 120 is maintained and repaired, it only needs to remove the box body 110 from the car frame, and there is no need to disassemble the structure of the car itself, which is simple to operate and saves time and effort.

[0038] The box body 110 has a front cover plate 113, a rear cover plate 114, a top plate 115, a left sealing plate 116 and a right sealing plate 117. The top plate 115, the left sealing plate 116 and the right sealing plate 117 are respectively connected to the front cover plate 113 and the rear cover plate 114. The opposite ends of the rolling shutter assembly 120 are respectively connected to the left sealing plate 116 and the right sealing plate 117. A winding and unwinding channel 111 is formed between the front cover plate 113 and the rear cover plate 114. The top end of the front cover plate 113 is provided with an assembly groove 112 that passes through in the left and right directions.

[0039] Please refer to Figure 3 and Figure 4 , Figure 3 FIG. 1 is a schematic diagram of the structure of the top plate 115 at a first viewing angle. Figure 4 FIG. 1 is a schematic diagram of the structure of the top plate 115 from a second viewing angle.

[0040] In this embodiment, the front end of the top plate 115 is provided with a matching buckle 1151, and the matching buckle 1151 is buckled with the front cover plate 113. The rear end of the top plate 115 is provided with a first assembly hole 1152, and the top end of the rear cover plate 114 is folded forward to form an assembly skirt 1141, and the rear end of the top plate 115 overlaps the assembly skirt 1141; the box body 110 also includes bolts and T-nuts, and the assembly skirt 1141 has a limiting groove 1142, and the T-nut is installed in the limiting groove 1142, and the limiting groove 1142 limits the rotation of the T-nut, and the bolt passes through the first assembly hole 1152 and then extends into the limiting groove 1142 to match the T-nut.

[0041] In the actual assembly process, the matching buckle 1151 at the front end of the top plate 115 is first buckled with the front cover plate 113, and then the top plate 115 is rotated around the buckle until the top plate 115 overlaps the assembly skirt 1141 of the rear cover plate 114. Then, the bolts and T-nuts are assembled to complete the connection between the rear end of the top plate 115 and the rear cover plate 114. It can be understood that in this embodiment, T-nuts are used to improve the convenience of disassembling and assembling the top plate 115. Since the T-nuts cannot be rotated due to the limitation of the limiting groove 1142, in actual application, the operator can rotate the bolts on the outside of the top plate 115 to release the matching between the bolts and the T-nuts, thereby opening the top plate 115, which is convenient for maintenance and repair of the roller shutter assembly 120.

[0042] In this embodiment, in order to ensure the reliability of the connection structure, the number of the first assembly holes 1152 is multiple, and the multiple first assembly holes 1152 are sequentially spaced apart in the left-right direction at the rear end of the top plate 115, and the multiple first assembly holes 1152 are respectively connected to the rear cover plate 114 through a combination of multiple sets of bolts and T-nuts. In addition, the matching buckle 1151 is a slot structure with an opening generally facing the front end, and it passes through the top plate 115 in the left-right direction.

[0043] Please refer to Figure 5 , Figure 5 FIG. 1 is a schematic structural diagram of the front cover plate 113 .

[0044] The front cover 113 has a panel 1132 and a lining plate 1133, and the panel 1132 and the lining plate 1133 are spaced apart in the front-to-back direction. The bottom ends of the panel 1132 and the lining plate 1133 are connected to form two second assembly holes 1134, and the two second assembly holes 1134 are respectively located at the left and right ends of the panel 1132. The left sealing plate 116 and the right sealing plate 117 are respectively connected to the two second assembly holes 1134 by screws, and the top ends of the panel 1132 and the lining plate 1133 are spaced apart to form an assembly groove 112.

[0045] It is understandable that the two second assembly holes 1134 may be two independent hole structures, or may be the left and right ends of a channel that passes through the front cover plate 113 in the left-right direction.

[0046] Two third assembly holes 1135 are also provided at the top of the panel 1132. The two third assembly holes 1135 are respectively located at the left and right ends of the panel 1132. The left sealing plate 116 and the right sealing plate 117 are also respectively connected to the two third assembly holes 1135 by screws.

[0047] Similarly, the two third assembly holes 1135 may be two independent hole structures, or may be the left and right ends of a channel that passes through the front cover plate 113 in the left-right direction.

[0048] It can be understood that, whether it is the left sealing plate 116 or the right sealing plate 117, the lower part of the front end is fixed to the second assembly hole 1134 by screws, and the lower part of the front end is fixed to the third assembly hole 1135 by screws, thereby realizing reliable fixation of the left and right sealing plates 117 and the front end of the right sealing plate 117.

[0049] A mating flange 1131 is convexly provided on the rear side surface of the top end of the lining plate 1133, and a mating buckle 1151 provided on the front end of the top plate 115 is buckled with the mating flange 1131, that is, the mating flange 1131 is embedded in the mating buckle 1151. Corresponding to the structure of the mating buckle 1151, the mating flange 1131 in this embodiment extends from the left end to the right end of the lining plate 1133.

[0050] A first limiting flange 1136 is also protruded from the front surface of the top of the lining plate 1133, and a second limiting flange 1137 is protruded from the rear surface of the panel 1132. The first limiting flange 1136 and the second limiting flange 1137 are opposite to each other and spaced apart to form a limiting notch 1138, and the notch of the assembly groove 112 is connected to the outside through the limiting notch 1138.

[0051] In fact, the first limiting flange 1136 and the second limiting flange 1137 are used to be hung on the frame of the carriage. In practical applications, the beam structure on the carriage frame extends into one end of the assembly slot 112, and the first limiting flange 1136 and the second limiting flange 1137 are hung on the beam structure of the frame, limiting the beam structure of the carriage frame from exiting the notch of the assembly slot 112, thereby realizing the assembly of the box body 110 on the carriage frame.

[0052] Please refer to Figure 6 and Figure 7 , Figure 6 FIG. 1 is a schematic diagram showing the structure of the left sealing plate 116. Figure 7 Shown is a schematic structural diagram of the right sealing plate 117.

[0053] In order to avoid obstruction to the cooperation between the car body frame and the assembly groove 112 , in this embodiment, a left avoidance gap 1161 is opened on the left sealing plate 116 at a position corresponding to the assembly groove 112 , and a right avoidance gap 1171 is opened on the right sealing plate 117 at a position corresponding to the assembly groove 112 .

Furthermore, the rear ends of the left sealing plate 116 and the right sealing plate 117 are penetrated with a fourth matching hole 1183 and a fifth matching hole 1184, the fourth matching hole 1183 is at the lower part, and the fifth matching hole 1184 is at the upper part, and the fourth matching hole 1183 and the fifth matching hole 1184 are both used to connect with the rear cover plate 114.

[0055] In addition, the left sealing plate 116 and the right sealing plate 117 are also penetrated with multiple mounting holes 1185. The multiple mounting holes 1185 on the left sealing plate 116 are connected to the left end of the rolling shutter assembly 120, and the multiple mounting holes 1185 on the right sealing plate 117 are connected to the right end of the rolling shutter assembly 120.

[0056] Please refer to 8. Figure 8 FIG. 1 is a schematic structural diagram of the rear cover plate 114 .

[0057] The rear cover 114 includes a first plate body 1143 and a second plate body 1144.
