For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0029] Reference Figure 2 and Figure 3 In this embodiment of the utility model, a civil defense door with a hydraulic lifting threshold is used as a protective door, which includes a base component 100, a door leaf component 200, a hydraulic component 300, and a threshold component 400.
[0030] The base component 100 has a flat surface 110 with a clearance opening 111 communicating with the inner cavity of the base component 100. The door leaf component 200 is rotatably mounted on the upper side of the flat surface 110. The hydraulic component 300 is located in the inner cavity of the base component 100. The sill component 400 is connected to the hydraulic component 300, and the clearance opening 111 cooperates with the sill component 400. The door leaf component 200 and the sill component 400 are arranged one behind the other. The hydraulic component 300 can drive the sill component 400 to rise or fall through the clearance opening 111, so that the sill component 400 can move to a position higher than the bottom of the door leaf component 200, or to a position flush with the flat surface 110. The door leaf components 200 are rotatably mounted on the upper side of the flat surface 110 via a door frame component. There are two door leaf components 200 arranged in a double-opening configuration. The hydraulic components 300 are hydraulic cylinders, and there are four hydraulic components 300.
[0031] With the above structure, on the one hand, the user can drive the threshold 400 to rise through the hydraulic component 300, so that it moves to a position higher than the bottom of the door leaf 200, thereby improving the overall protection and sealing effect of the blast door after the door leaf 200 is rotated and closed; on the other hand, when the door leaf 200 is rotated and opened, the user can drive the threshold 400 to fall through the hydraulic component 300, so that it moves to a position flush with the plane 110, thereby facilitating the passage of people or vehicles.
[0032] Understandably, the threshold 400 is higher than the bottom of the door leaf 200 so that it can abut against the rear side of the door leaf 200 after the door leaf 200 is rotated and closed, thereby improving the overall protection and airtightness of the blast door.
[0033] In some embodiments, the hydraulic components 300 are configured as five, etc.
[0034] In this embodiment, refer to Figure 2 and Figure 3 It also includes a drive module 500, which is connected to the hydraulic component 300. The drive module 500 has a rotatable drive component 510. Rotating the drive component 510 can drive the hydraulic component 300 to move, thereby causing the sill component 400 to rise or fall. The drive module 500 is an oil pump module, and the drive component 510 is a handwheel component.
[0035] In some embodiments, refer to Figure 1 The drive component 510 can be set as a rocker arm component.
[0036] In this embodiment, refer to Figure 2The drive module 500 is provided with a control component 520, which has a first state, a second state, and a third state. When the control component 520 is in the first state, the rotation drive member 510 can drive the hydraulic member 300 to move, thereby driving the sill member 400 to rise. When the control component 520 is in the second state, the rotation drive member 510 can drive the hydraulic member 300 to move, thereby driving the sill member 400 to fall. When the control component 520 is in the third state, the hydraulic member 300 stops moving, so that the sill member 400 is placed in the corresponding position.
[0037] It is understandable that the control component 520 is configured as an oil circuit valve assembly, and the control component 520 can control the opening and closing of the oil circuit to specifically control the hydraulic component 300 to rise, fall, or stop.
[0038] With the above structure, the user needs to first adjust the control component 520 to the first, second, or third state before the sill piece 400 can be driven to rise, fall, or stop at the corresponding position. Therefore, the sill piece 400 can be accurately driven to rise, fall, or stop at the corresponding position.
[0039] Reference Figure 5 and Figure 6 In an embodiment of this utility model, a civil defense door with a hydraulic lifting threshold is a sealed door, which includes a base component 100, a door leaf component 200, a hydraulic component 300, and a threshold component 400.
[0040] The base component 100 has a flat surface 110 with a clearance opening 111 communicating with the inner cavity of the base component 100. The door leaf component 200 is rotatably mounted on the upper side of the flat surface 110. The hydraulic component 300 is located in the inner cavity of the base component 100. The sill component 400 is connected to the hydraulic component 300, and the clearance opening 111 cooperates with the sill component 400. The door leaf component 200 and the sill component 400 are arranged one in front of the other. The hydraulic component 300 can drive the sill component 400 to rise or fall through the clearance opening 111, so that the sill component 400 can move to a position higher than the bottom of the door leaf component 200, or to a position flush with the flat surface 110. The door leaf component 200 is rotatably mounted on the upper side of the flat surface 110 via a door frame component, and there is one door leaf component 200. The hydraulic component 300 is a hydraulic cylinder component, and there are four hydraulic components 300.
[0041] With the above structure, on the one hand, the user can drive the threshold component 400 to rise through the hydraulic component 300, so that the threshold component 400 moves to a position higher than the bottom of the door leaf component 200, thereby improving the overall protection and airtightness of the blast door after the door leaf component 200 is rotated and closed; on the other hand, when the door leaf component 200 is rotated and opened, the user can drive the threshold component 400 to fall through the hydraulic component 300, so that the threshold component 400 moves to a position flush with the plane 110, thereby facilitating the passage of people or vehicles.
[0042] Understandably, the threshold 400 is higher than the bottom of the door leaf 200 so that it can abut against the rear side of the door leaf 200 after the door leaf 200 is rotated and closed, thereby improving the overall protection and airtightness of the blast door.
[0043] In some embodiments, the hydraulic components 300 are configured as five, etc.
[0044] In this embodiment, refer to Figure 5 and Figure 6 It also includes a drive module 500, which is connected to the hydraulic component 300. The drive module 500 has a rotatable drive component 510. Rotating the drive component 510 can drive the hydraulic component 300 to move, thereby causing the sill component 400 to rise or fall. The drive module 500 is an oil pump module, and the drive component 510 is a handwheel component.
[0045] In some embodiments, refer to Figure 4 The drive component 510 can be set as a rocker arm component.
[0046] In this embodiment, refer to Figure 5 The drive module 500 is provided with a control component 520, which has a first state, a second state, and a third state. When the control component 520 is in the first state, the rotation drive member 510 can drive the hydraulic member 300 to move, thereby driving the sill member 400 to rise. When the control component 520 is in the second state, the rotation drive member 510 can drive the hydraulic member 300 to move, thereby driving the sill member 400 to fall. When the control component 520 is in the third state, the hydraulic member 300 stops moving, so that the sill member 400 is placed in the corresponding position.
[0047] It is understandable that the control component 520 is configured as an oil circuit valve assembly, and the control component 520 can control the opening and closing of the oil circuit to specifically control the hydraulic component 300 to rise, fall, or stop.
[0048] With the above structure, the user needs to first adjust the control component 520 to the first, second, or third state before the sill piece 400 can be driven to rise, fall, or stop at the corresponding position. Therefore, the sill piece 400 can be accurately driven to rise, fall, or stop at the corresponding position.
