Description

Technical Field

[0001] The utility model relates to the technical field of marine airtight locks, in particular to a wind and rain tight airtight lock. Background Art

[0002] Weathertight wind gates are mainly used for air vents within the ship's weathertight lines to prevent rainwater from entering the cabin when wind and rain are greater than normal or in special circumstances. Weathertight wind gates can be divided into manual and automatic control; the most common manual ones are cover-type shutters and handwheel-type shutters; automatic control can be divided into pneumatic and electric-controlled weathertight wind gates. After consulting with multiple domestic shutter manufacturers, the current maximum angle of handwheel-type shutters can reach 60 degrees; the angle of automatic weathertight wind gates is about 55 degrees.

[0003] For example, in the Chinese patent publication number CN218623988U, although the lever structure is formed by the louver, connecting rod, central axis connecting rod and cylinder, the driving force of the cylinder required to open the louver is relatively small. On the contrary, when the cylinder loses gas pressure, the cylinder performs the action of closing the louver. Therefore, the cylinder will not hinder the closing of the louver.

[0004] However, the applicant discovered that when the above-mentioned comparative patent drives the central axis connecting rod and the connecting rod to move and open the louvers through the cylinder, the central axis connecting rod is restricted by the position of the window frame, so that the movement displacement of the central axis connecting rod is limited. Without changing the position and size of the window rod, the opening angle of the louvers is limited, thereby reducing the ventilation efficiency of the air outlet. Summary of the invention

[0005] In view of this, the purpose of the utility model is to propose a wind and rainproof damper to solve the problem that, without changing the position and size of the window rod, the vertical rod is restricted by the position of the window rod, so that the displacement of the vertical rod is limited, and the opening angle of the damper blade is limited, resulting in a smaller opening angle and lower ventilation efficiency of the air outlet.

[0006] Based on the above purpose, the utility model provides a wind and rain-tight damper, comprising a window body, a plurality of window rods are installed in the window body, and an air outlet is formed between two adjacent window rods, and a plurality of damper blades are rotatably connected to the window rods for shielding the air outlet, and a vertical rod is also arranged in the window body, wherein a transmission part is arranged between each damper blade and the vertical rod;

[0007] The window body is also provided with a driving part for pushing the vertical rod to move. When ventilation is required through the air outlet, the driving part pushes the vertical rod to move. With the cooperation of the transmission part, each damper blade is opened, and the maximum opening of the damper blade can reach 90°.

[0008] Preferably, the transmission part includes a cross bar fixedly connected to the wind brake blade, the end of the cross bar is folded upward to form a bending rod, the end of the bending rod close to the vertical rod is rotatably connected to an extension rod through a pin, and the extension rod is fixedly connected to the vertical rod.

[0009] Preferably, the angle between the cross bar and the bending bar is 135°.

[0010] Preferably, the driving part comprises a cylinder hinged in the window body, and the output end of the cylinder is hinged to the vertical rod.

[0011] Preferably, the cylinder is hinged on the top of the inner wall of the window through a hinge seat 1, and the output end of the cylinder is hinged on the surface of the vertical rod near its bottom end through a hinge seat 2.

[0012] Preferably, a rubber pad is fixedly connected to one side of the window rod close to the vertical rod.

[0013] Beneficial effects of the utility model: the utility model provides a wind and rainproof damper, which, through the setting of the transmission part, when ventilation is needed through the air outlet, the driving part pushes the vertical rod to move, and with the cooperation of the transmission part, each damper blade is opened, and the maximum opening of the damper blade can reach 90°, which solves the problem of limited maximum opening of existing damper blades and increases the ventilation efficiency of the air outlet.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a wind and rainproof damper comprises a window body 1, a plurality of window rods 2 are installed in the window body 1, and an air outlet is formed between two adjacent window rods 2, and a plurality of damper blades 3 are rotatably connected to the window rods 2 for blocking the air outlet. A vertical rod 4 is also arranged in the window body 1, wherein a transmission part 5 is arranged between each damper blade 3 and the vertical rod 4.

[0022] A driving part 6 for pushing the vertical rod 4 to move is also provided in the window body 1. When ventilation is required through the air outlet, the driving part 6 pushes the vertical rod 4 to move. With the cooperation of the transmission part 5, each damper blade 3 is opened, and the maximum opening of the damper blade 3 can reach 90°.

[0023] In the existing method, when the damper blades 3 are opened, the vertical rod 4 is blocked and restricted by the window rod 2, so that the displacement of the vertical rod 4 is limited. Without changing the position and size of the window rod 2, the opening angle of the damper blades 3 is limited. By setting the transmission part 5, the driving part 6 pushes the vertical rod 4 to move. With the cooperation of the transmission part 5, each damper blade 3 is opened, and the maximum opening of the damper blade 3 can reach 90°, which solves the problem of the maximum opening of the damper blade 3 being limited and increases the ventilation efficiency of the air outlet.

[0024] In a preferred embodiment of the utility model, the transmission part 5 includes a cross bar 51 fixedly connected to the wind brake blade 3, and the end of the cross bar 51 is folded upward to form a bending rod 52, and the angle between the cross bar 51 and the bending rod 52 is 135°. The end of the bending rod 52 close to the vertical rod 4 is rotatably connected to an extension rod 53 through a pin shaft, and the extension rod 53 is fixedly connected to the vertical rod 4.

[0025] When the vertical rod 4 contacts the window rod 2 under the drive of the driving part 6, the pushing distance of the vertical rod 4 is increased through the setting of the extension rod 53, that is, the extension rod 53 increases the pushing distance when the wind gate blade 3 is opened outward, and through the bending setting between the cross rod 51 and the bending rod 52, when the vertical rod 4 moves to contact the window rod 2, under the transmission of the extension rod 53, the cross rod 51 can be pushed to the vertical state to the maximum extent, so that the cross rod 51 can push the opening of the wind gate blade to 90°, thereby improving the ventilation efficiency of the air outlet.

[0026] In another preferred embodiment of the present utility model, the driving part 6 comprises a cylinder 61 hinged in the window body 1 , and the output end of the cylinder 61 is hinged to the vertical rod 4 .

[0027] When it is necessary to open the damper blade 3, one end of the cylinder 61 is hinged to the window 1, and the other end is hinged to the vertical rod 4, so that the cylinder 61 is started to push the vertical rod 4 to move, and under the transmission of the extension rod 53, the cross rod 51 and the bending rod 52, the damper blade 3 can be opened for ventilation.

[0028] It should be noted that the cylinder 61 is hinged to the top of the inner wall of the window 1 through the hinge seat 1 62, and the output end of the cylinder 61 is hinged to the surface of the vertical rod 4 near its bottom end through the hinge seat 2. The hinge seat 1 62 and the hinge seat 2 are both detachably installed by bolts.

[0029] It should be noted that a rubber pad 7 is fixedly connected to one side of the window rod 2 close to the vertical rod 4. The rubber pad 7 protects the window rod 2 and the vertical rod 4. When the cylinder 61 pushes the vertical rod 4 to move and contact the window rod 2, the rubber pad 7 plays a buffering role on the one hand, reducing the vibration of the window rod 2, and on the other hand, protects both and reduces wear.
