Description

Technical Field

[0001] The invention relates to the technical field of blinds, in particular to an outdoor closing device for blinds. Background Art

[0002] Traditional marine engineering generally uses straight bulkheads, and shutters are installed on the bulkheads. The marine standard "CB / T749-1997 Fixed Steel Shutters" can be used. At present, corrugated plate trough bulkheads are often used on offshore booster station platforms. Ships are generally equipped with various types of shutters, which are mainly used for natural ventilation and lighting of the premises to prevent rain or debris from entering. When closed, they can meet the requirements of wind and rain tightness or fire integrity. When a fire occurs in the engine room, closing the engine room shutters can prevent the "chimney effect" and prevent the leakage of C02 gas used for fire extinguishing. Gas-controlled shutters are generally installed on the engine room chimney of large ships, which are several floors high from the engine room platform. People on board are often reluctant to climb, resulting in the shutters not being regularly activated and maintained, and problems are not discovered. Therefore, regular maintenance and operation tests of the shutters are necessary.

[0003] However, since the shutters of traditional ships need to be opened and closed inside the cabin and cannot be closed from the outside of the cabin, it is difficult to close the windows in an emergency when there is no one in the cabin. Summary of the invention

[0004] In view of the existing problems, the present invention provides an outdoor closing device for shutters, which can effectively solve the problems raised in the background technology when used in combination.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0006] The outdoor closing device of the shutter comprises a window frame, a driving bin is provided at one side end of the window frame, a movable groove is provided at the inner side wall of the window frame, a fan blade is installed in the internal array of the window frame, the interior of the fan blade passes through the driving bin and is connected to a fan blade rotating shaft, a fan blade gear is installed at the outer end of the fan blade rotating shaft, a rack is sleeved on the outer side of the fan blade gear, an outer opening and closing bin is installed at the lower end of the front surface of the window frame, an inner opening and closing bin is installed at the lower end of the rear surface of the window frame, an opening and closing mechanism is arranged inside the outer opening and closing bin, the opening and closing mechanism comprises a pull ring, a pawl, and a ratchet gear, an elastic rotating shaft is connected between the pawl and the outer opening and closing bin, a winding roller is installed inside the ratchet gear, a second direction adjustment bracket is installed on the inner side wall of the driving bin above the ratchet gear, a first direction adjustment bracket is installed on the inner side wall of the driving bin above the second direction adjustment bracket, and a switch pull rope is connected between the winding roller and the rack.

[0007] As a further solution of the present invention: a second ratchet gear is arranged inside the inner opening and closing bin, a second pawl is installed on one side of the second ratchet gear located inside the inner opening and closing bin, and a second pull ring is connected to one side of the second pawl.

[0008] As a further solution of the present invention: a first tension spring is connected between one side above the rack and the driving chamber, and a second tension spring is connected between the other side above the rack and the driving chamber.

[0009] As a further solution of the present invention: the inner wall of the drive bin is provided with a snap-in groove, the upper end of the snap-in groove is located on the upper surface of the window frame and is provided with an upper snap-in groove, and a snap-in cover plate is installed inside the snap-in groove.

[0010] As a further solution of the present invention: one end of the first direction-adjusting bracket and the second direction-adjusting bracket is connected to a fixed pulley via a rotating shaft, and an anti-leakage protrusion is installed on the upper surface of the fan blade.

[0011] As a further solution of the present invention: the rack is meshed and clamped with the fan blade gear, and the switch pull rope is fixedly connected to the rack and the winding roller.

[0012] As a further solution of the present invention: the ratchet is fixedly connected to the outer opening and closing compartment via the elastic rotating shaft, and the first direction adjustment bracket and the second direction adjustment bracket are both fixedly connected to the driving compartment.

[0013] As a further solution of the present invention: the first tension spring and the second tension spring are both fixedly connected to the rack.

[0014] As a further solution of the present invention: the anti-leakage protrusion is fixedly connected to the fan blade, and the fixed pulley is connected to the first direction-adjusting bracket and the second direction-adjusting bracket via a rotating shaft.

[0015] As a further solution of the present invention: the ratchet gear is connected to the outer opening and closing bin rotating shaft, and the elastic rotating shaft is meshed and engaged with the ratchet gear.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Apply tension to the pull ring as a whole to make the pawl rotate through the elastic shaft and the outer opening and closing bin. After disconnecting the clamping limit function of the pawl and the ratchet gear, apply torque to the rocker connected to the outside of the ratchet gear to make the winding roller inside the ratchet gear wind up the switch pull rope, so that the switch pull rope drives the rack to move as a whole. After the rack moves, it will mesh and rotate with the fan blade gear, so that the fan blade gear will drive the fan blade shaft to drive the fan blades arranged in the array inside the window frame to rotate, so as to open and close the window.

[0018] 2. When the ratchet gear moves in the direction with the pawl, the second pawl will not limit the second ratchet gear. Similarly, when the second ratchet gear rotates in the direction of the second pawl, the pawl will not limit the ratchet gear. Therefore, when people are inside the cabin to open and close the window, they apply tension to the second pull ring and then apply torque to the second pawl to control the rack to drive the fan blade gear to rotate to control the opening and closing of the fan blade, so that the window frame as a whole can be opened and closed inside the cabin.

[0019] 3. When the fan blade shaft drives the fan blades arranged in the array inside the window frame to rotate, the fan blades at the upper position will cover the leak-proof protrusions of the fan blades at the lower position to reduce the gap at the connection and reduce the entry of debris into the cabin.

[0020] 4. A second tension spring and a first tension spring are connected between the two sides above the rack and the driving compartment. When the rack is controlled to drive the fan gear to rotate, the spring can reserve elastic potential energy after the window is closed, and when the window is opened, the window can be opened quickly under the action of the spring.
