Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hull shutters, in particular to a ventilation shutter. Background Art
[0002] With the continuous development of science and technology, the intelligent application of ships is becoming more and more popular. There are more and more mechanical and electrical precision equipment in the cabin, and the ventilation requirements for the cabin are getting higher and higher. The shutters commonly used in the existing technology are usually used for air intake in the cabin, and some old ships currently use conventional steel shutters. When the fan is running, rainwater will be sucked into the cabin through the conventional shutters and enter the cabin through the structural air duct, which will cause damage to some equipment running in the cabin; in addition, shutters with demisting and desalting functions mostly need to be imported from abroad, which is relatively expensive.
[0003] The shutter blades commonly used in the prior art are usually installed at a 45° angle downward, which can prevent some rainwater from entering the room when it rains. However, when the rain is irregular or the sea water is stirred up, the rainwater will float into the room. At the same time, most of the current ventilation shutters are installed by bolting on the outside of the hull, and there are many bolts exposed on the installation edge, which makes the bolts easy to rust and is difficult to install. Utility Model Content
[0004] The purpose of the utility model is to provide a ventilation shutter that can solve at least one of the above technical problems. The technical solution of the utility model is as follows:
[0005] A ventilation shutter comprises: a hull shell, a mounting groove is opened on the hull shell, a shutter frame is installed in the mounting groove, a plurality of lining strips are longitudinally fixed in the shutter frame, a fixing rod is provided on one side of each of the lining strips, and a plurality of ventilation shutters are connected to each of the fixing rods.
[0006] Furthermore, screws are passed through the inner lining strip and the fixing rod, and nuts are threadedly matched at the ends of the screws.
[0007] Furthermore, a plurality of hooks are provided on the shutter frame.
[0008] Furthermore, the ventilation louver is in the shape of a thin-walled triangle, the front side of the ventilation louver is open, and the ventilation louver is welded and fixed on a fixing rod.
[0009] Preferably, the shutter frame is circular, and the ventilation shutters are arranged in the shutter frame according to the shape of the shutter frame.
[0010] Preferably, the shutter frame is square.
[0011] Preferably, the shutter frame is installed and fixed in the installation groove in a thin-walled shape, and has a protruding edge extending in an arc shape at the rear side of the shutter frame.
[0012] In summary, the beneficial effects of the present invention compared with the prior art are as follows:
[0013] The utility model provides a ventilation shutter, which when in use, the user installs and fixes the shutter frame in the installation groove, and then fixes the fixing rod on the lining strip through screws and nuts, so that the ventilation shutter is installed and set. Since most of the screws are arranged between the lining strip and the fixing rod, the screws are prevented from contacting with moisture. The wind shutter is in a thin-walled triangle shape, so that the ventilation shutter can block rainwater from the upper and lower sides. Compared with the existing technology, it can prevent rainwater from the upper and lower sides from drifting into the hull. At the same time, the bolts for installing the shutter can be arranged in the shutter frame to prevent the bolts from rusting, thereby reducing the difficulty of installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Explanation of the reference numerals: 1. hull shell; 2. mounting groove; 3. shutter frame; 4. lining strip; 5. fixing rod; 6. ventilation shutter; 41. screw; 42. nut; 31. hook; 32. protruding edge. DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0018] like Figures 1 to 2 A ventilation shutter is shown, characterized in that it includes: a hull shell 1, a mounting groove 2 is opened on the hull shell 1, a shutter frame 3 is installed in the mounting groove 2, a plurality of lining strips 4 are longitudinally fixed in the shutter frame 3, a fixing rod 5 is provided on one side of each of the lining strips 4, screws 41 are passed through the lining strips 4 and the fixing rods 5, nuts 42 are threadedly engaged with the ends of the screws 41, and a plurality of ventilation shutters 6 are connected to each of the fixing rods 5, the ventilation shutters 6 are thin-walled triangles, the front sides of the ventilation shutters 6 are open, and the ventilation shutters 6 are welded and fixed to the fixing rods 5.
[0019] A ventilation shutter of the above structure, when in use, the user installs and fixes the shutter frame 3 in the installation groove 2, and then fixes the fixing rod 5 on the lining strip 4 through the screw 41 and the nut 42, so that the ventilation shutter 6 is installed. Since most of the screws 41 are arranged between the lining strip 4 and the fixing rod 5, the screws 41 are prevented from contacting with moisture. The ventilation shutter 6 is a thin-walled triangle, so that the wind shutter can block rainwater from both sides. Compared with the existing technology, it can prevent rainwater from both sides from drifting into the hull. At the same time, the bolts for installing the shutter can be set in the shutter frame to prevent the bolts from rusting, thereby reducing the difficulty of installation.
[0020] like Figure 1 As shown, a plurality of hooks 31 are provided on the shutter frame 3, and the plurality of hooks 31 provided on the shutter frame 3 can facilitate the people inside to hang articles.
[0021] like Figure 1 As shown, the shutter frame 3 is circular, and the ventilation shutters 6 are arranged in the shutter frame 3 according to the shape of the shutter frame 3 .
[0022] It should be noted that the shutter frame 3 is square in shape. In order to meet the user's requirements for the shape of the shutter, the ventilation shutters 6 can be arranged in the shutter frame 3 according to the shape of the shutter frame 3 .
[0023] like Figure 2 As shown, the shutter frame 3 is installed and fixed in the installation groove 2 in a thin-walled shape, and a protruding edge 32 is extended in an arc shape on the rear side of the shutter frame 3. The thin-walled shutter frame 3 can reduce the manufacturing cost during production. Only a thin-walled metal plate is needed to form the shutter frame 3. At the same time, the protruding edge 32 is extended in an arc shape on the rear side of the shutter frame 3, which can limit the shutter frame 3 to be installed in the installation groove 2 and also play an anti-collision function.
