All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] For example, see Figure 1-21The present invention provides a technical solution: a ship porthole with enhanced assembly stability, comprising a main window frame 1, a glass pressure plate 2 and a storm cover 3, wherein the glass pressure plate 2 and the storm cover 3 are fixedly connected to the main window frame 1 by movable bolts respectively, a movable wedge 31 is fixedly installed on the inner side of the lower end of the storm cover 3, an embedded ring groove 20 is provided on the inner wall of the outer side of the glass pressure plate 2, a pressure plate mounting outer ring 21 is fixedly connected to the outer side of the embedded ring groove 20 by bolts, a reserved groove 200 is provided on the lower end of the pressure plate mounting outer ring 21, a reinforcement inner ring 22 is provided between the pressure plate mounting outer ring 21 and the glass pressure plate 2, the outer surface of the reinforcement inner ring 22 is adaptively fitted with the inner wall of the embedded ring groove 20, an arc groove is provided on the inner wall of the lower end of the reinforcement inner ring 22, a fixed wedge 23 is fixedly installed on the inner wall of the arc groove, a circular assembly groove 2200 is provided through the upper end of the arc groove, and the circular assembly groove 2200 is provided. A cover-mounted tight fitting mechanism 4 is installed on the inner side of the matching groove 2200, and a vacuum mechanism 5 is installed on one side of the cover-mounted tight fitting mechanism 4. The cover-mounted tight fitting mechanism 4 includes a basic cylinder seat 41, a central limiting straight pipe 42, a movable blocking plug 43, an airflow converter 44, a piston member 45 and a limiting ridge rod 46; a slot 1 210 is provided on the outer inner wall of the pressure plate mounting outer ring 21, and a slot 220 adapted thereto is provided on the outer inner wall of the reinforced inner ring 22. The inner surfaces of the slot 1 210 and the slot 2 220 are respectively adapted and embedded with the outer surface of the movable wedge block 31, and a matching slope 1 is provided on the lower side surface of the movable wedge block 31, and a matching slope 2 is provided on the upper side surface of the fixed wedge block 23. The matching slope 1 is adapted to be connected with the matching slope 2, and a locking groove 1 230 is provided on the inner wall of the fixed wedge block 23, and a locking groove 2 310 is provided on the inner wall of the movable wedge block 31;

[0043] In this embodiment, the glass pressure plate 2, the storm cover 3 and the main window frame 1 are tightly matched in sequence by means of movable bolts. The glass pressure plate 2, the pressure plate mounting outer ring 21 and the reinforcement inner ring 22 are designed as a whole in a modular manner. The reinforcement inner ring 22 is integrated between the glass pressure plate 2 and the inner side of the pressure plate mounting outer ring 21. When the storm cover 3 and the glass pressure plate 2 are covered, the movable wedge 31 is first inserted into the inner side of the reinforcement inner ring 22 through the slot 1 210 and the slot 2 220. At this time, the movable wedge 31 and the fixed wedge 23 are adapted to fit together. In this way, before the storm cover 3 and the glass pressure plate 2 are fastened by the movable bolts, Now, a preliminary limit is performed. When the storm cover 3 and the glass pressure plate 2 are tightened, the movable blocking bolt 43 is controlled to descend to achieve the sealing of the circular assembly groove 2200. At the same time, the movable wedge block 31 and the fixed wedge block 23 that are in contact with each other are locked from top to bottom. In this way, multiple locking between the glass pressure plate 2 and the storm cover 3 is achieved to avoid the poor stability of the porthole caused by various external forces and impacts. This further solves the problem that when the existing porthole faces severe sailing conditions such as waves, the storm cover, the glass pressure plate and the window frame are easily affected by various external forces and vibrations, resulting in looseness and insufficient stability among the three.

[0044] Embodiment 2, refer to the attached Figure 1-21 On the basis of the first embodiment, in order to realize the installation cooperation between the overall structure of the cover-mounted tight-fitting mechanism 4 and the reinforced inner ring 22: the lower end outer surface of the basic cylinder seat 41 penetrates the inner wall of the pressure plate mounting outer ring 21, the upper side outer surface of the basic cylinder seat 41 penetrates the inner wall of the fixed wedge block 23 and is fixedly connected thereto, and the center limit straight tube 42 is fixedly installed on the inner side of the basic cylinder seat 41; the upper end inner surface of the movable plugging plug 43 is fixedly installed with a sliding seat 431, and the inner surface of the sliding seat 431 is connected to the upper side outer surface of the center limit straight tube 42. The outer surface of the movable plugging bolt 43 is movably connected with the inner wall of the circular assembly groove 2200, and ventilation grooves 430 are evenly opened on the lower inner wall of the movable plugging bolt 43; a sealing ring is fixedly sleeved on the outer annular surface of the movable plugging bolt 43, and an elastic pad 2201 is fixedly installed on the inner surface of the circular assembly groove 2200, and the thickness of the elastic pad 2201 is greater than the depth of the circular assembly groove 2200, and the inner annular surface of the elastic pad 2201 is movably engaged with the outer surface of the movable plugging bolt 43;

[0045] In this embodiment, the basic cylinder seat 41 and the center limit straight tube 42 cooperate with each other and can serve as a limit support member for the movable plugging plug 43. The basic cylinder seat 41 and the center limit straight tube 42 are integrated with the fixed wedge 23, and the basic cylinder seat 41 and the center limit straight tube 42 form a gas channel. Fig.11 As shown, ventilation grooves 430 are evenly provided on the lower annular surface of the movable sealing bolt 43. When the movable sealing bolt 43 is lifted, the ventilation grooves 430 are in a leakage state. When the movable sealing bolt 43 is lowered, the sealing ring connected to the outer annular surface of the movable sealing bolt 43 contacts with the elastic pad 2201 on the inner side of the circular assembly groove 2200. The elastic pad 2201 is deformed due to the compression from the inside, and a reverse elastic force is generated to tighten the movable sealing bolt 43, thereby achieving a sealing effect of the movable sealing bolt 43 in the sealing state. In this way, the air in the cavity formed by the glass pressure plate 2 and the storm cover 3 is extracted only through the exhaust mechanism 5.

[0046] Embodiment 3, refer to the attached Figure 1-21 On the basis of the second embodiment, in order to achieve the stability of the movable blocking bolt 43 during the lifting process: a limiting convex edge is fixedly added to the outer ring surface of the lower end of the movable blocking bolt 43, and a limiting column 434 is arranged on the inner wall of the limiting convex edge. The outer surface of the limiting column 434 is movably connected to the inner wall of the limiting convex edge. A spring 433 is movably sleeved on the upper side of the limiting column 434. The upper end of the spring 433 is fixedly connected to a limiting ring 1 432. The limiting ring 1 432 is fixedly installed on the top surface of the inner cavity of the arc groove. The other end of the limiting ring 1 432 is fixedly connected to the upper surface of the limiting convex edge. The upper end of the limiting column 434 is fixedly connected to the lower surface of the limiting ring 1 432. The lower end of the limiting column 434 is fixedly connected to a supporting base 435.

[0047] In this embodiment, when the movable blocking bolt 43 is in the lifting and lowering motion state, the movable blocking bolt 43 moves along the longitudinal direction of the limiting column 434. During the lifting and lowering process of the movable blocking bolt 43, the spring 433 will be subjected to telescopic deformation. At this time, the limiting column 434 cooperates with the spring 433, which can not only maintain the stability of the lifting and lowering of the movable blocking bolt 43, but also weaken the shaking of the movable blocking bolt 43 caused by external force to a certain extent. Moreover, by combining the support base 435 with the limiting column 434, the limiting column 434 can be limited and supported, and a supporting effect can be provided for the installation of the basic cylinder seat 41 and the center limiting straight tube 42.

[0048] Embodiment 4, refer to the attached Figure 1-21 On the basis of the third embodiment, in order to ensure that the movable blocking bolt 43 can move up and down, the fixed wedge 23 and the movable wedge 31 are locked: the lower end of the basic cylinder seat 41 is fixedly connected to the upper surface of the support base 435, the airflow converter 44 is arranged on one side of the basic cylinder seat 41, the airflow converter 44 passes through the inner wall of the fixed wedge 23, the input end of the airflow converter 44 is provided with a gas adapter joint, and the output end of the airflow converter 44 is respectively provided with a lower air pipe 441 and an upper air pipe 442, and the air outlet ends of the lower air pipe 441 and the upper air pipe 442 respectively pass through the inner wall of the basic cylinder seat 41 and the center limit straight pipe 42; the piston member 45 is movably installed on the inner side of the center limit straight pipe 42; the upper end outer surface of the limiting ridge rod 46 is fixedly connected to the upper end inner wall of the movable blocking bolt 43, and the limiting The lower outer surface of the positioning edge rod 46 is fixedly connected with a fixed gear rod 461, and the lower outer surface of the fixed gear rod 461 is slidably connected with the inner walls of the locking groove 2 310 and the locking groove 230 respectively; the inner surface of the fixed gear rod 461 is meshed and rotated with a rotating tooth 462, and the two sides of the rotating tooth 462 are rotatably connected with a limiting liner rod 410, and the lower end of the limiting liner rod 410 is fixedly connected with a side surface of the base cylinder seat 41, and the outer surface of the rotating tooth 462 is meshed and rotated with a fixed gear rod 463, and the side surface of the fixed gear rod 463 away from the rotating tooth 462 is fixedly installed with a magnetic sliding ring 464, and the magnetic sliding ring 464 is slidably installed on the outer surface of the central limiting straight tube 42, and the outer surface of the piston member 45 is fixedly installed with a magnetic sleeve ring, and the magnetic sleeve ring and the magnetic sliding ring 464 are electrically connected;

[0049] In this embodiment, after the glass pressure plate 2 and the storm cover 3 are covered, the movable blocking bolt 43 needs to be lowered so that the ventilation groove 430 is on the inner side of the reinforced inner ring 22 to ensure that the fixed block 23 and the movable block 31 are further locked before the exhaust mechanism 5 is driven. The specific operation is to connect air to the air flow converter 44 through the gas adapter joint, and inject gas into the bottom of the piston member 45 through the lower air pipe 441. At this time, the bottom of the piston member 45 is pushed upward by the gas. At this time, the magnetic sleeve installed on the piston member 45 moves synchronously, and the magnetic sleeve is electrically connected to the magnetic sliding ring 464. The two are two magnetic poles of opposite sexes that attract each other. When the magnetic sleeve moves upward, the magnetic sliding ring 464 moves on the surface of the center limit straight tube 42. At this time, the fixed gear rod 463 moves upward, driving the rotating gear 462 to rotate, and at this time, the fixed gear rod 461 is adapted to mesh with the rotating gear 462, and the fixed gear rod 461 moves downward, and its lower end is formed by a locking groove 2310 opened on the movable wedge block 31 and penetrates the inner wall of the locking groove 230, so as to realize the secondary locking after the initial limiting between the fixed wedge block 23 and the movable wedge block 31; it is worth noting that the upper end of the limiting edge rod 46 is connected to the induction ring, which is a semiconductor gas induction ring, and the induction ring is electrically connected to the exhaust mechanism 5, the limiting edge rod 46 can be used as a support member for the fixed gear rod 461, and can also be used as a support member for the induction ring, after the induction ring senses that the pressure in the cavities of the glass pressure plate 2 and the storm cover 3 reaches the preset value, the exhaust mechanism 5 stops operating.

[0050] Embodiment 5, refer to the attached Figure 1-21 On the basis of the fourth embodiment, in order to achieve the unlocking of the fixed wedge block 23 and the movable wedge block 31, air is injected into the cavity of the glass pressure plate 2 and the storm cover 3 to avoid the situation that the storm cover 3 is difficult to open: the piston member 45 is composed of a piston plate and a piston rod, and a circular sealing plate is fixedly installed on the upper end of the piston rod. The outer surface of the circular sealing plate is movably connected to the inner wall of the central limit straight tube 42, and a buffer groove 450 and an air inlet 4500 are opened on the inner wall of the upper end of the piston plate. The buffer groove 450 and the air inlet 4500 are connected to the air inlet 4500. 00 are mutually connected; a saturated gas injection assembly is arranged on the piston member 45, and the saturated gas injection assembly includes an abutting elastic wire 4502, the lower end of the abutting elastic wire 4502 is fixedly connected to the bottom surface of the inner cavity of the buffer groove 450, and the upper end of the abutting elastic wire 4502 is fixedly connected to a T-shaped pressing block 4501, and the T-shaped pressing block 4501 is movably installed on the inner side of the buffer groove 450, and the inner side annular surface of the air inlet 4500 is connected to the gas injection pipe 4503, and the output end of the gas injection pipe 4503 extends to the upper end outer surface of the circular sealing plate;

[0051] In this embodiment, when gas is injected into the central limit straight tube 42 through the upper gas pipe 442, the gas enters the upper position of the piston plate. At this time, a sealed cavity is formed between the piston plate and the circular sealing plate. When the gas in the cavity is continuously replenished, Fig.16 As shown, the excess gas will compress the T-shaped pressing block 4501 provided on the piston plate, so that the T-shaped pressing block 4501 moves downward under the pressure of the gas, and the elastic wire 4502 is squeezed. At this time, the gas enters the channel of the gas injection pipe 4503 through the air inlet 4500, and the gas then passes through the top position of the circular sealing plate to discharge the air outward, so that the air is slowly injected between the inner cavity of the glass pressing plate 2 and the storm cover 3 to balance the internal and external pressures; and it should be noted that when the upper part of the piston plate is compressed by the gas, the piston member 4 5 is lowered as a whole, thus driving the fixed gear rod 2 463 to lower. At this time, the fixed gear rod 1 461 drives the limiting edge rod 46 and the movable blocking bolt 43 to rise as a whole. When the bottom position of the fixed gear rod 2 463 is blocked by the limiting lining rod 410 and cannot be lowered, the fixed gear rod 1 461 rises to release the restriction on the fixed block 23 and the movable block 31. In this way, while releasing the restriction, air is injected into the cavity formed by the glass pressure plate 2 and the storm cover 3, so as to facilitate unlocking and reduce the difficulty of opening the storm cover 3.

[0052] Embodiment 6, refer to the attached Figure 1-21 On the basis of the fifth embodiment, the present invention further provides a method for using a ship porthole with enhanced assembly stability, comprising the following steps:

[0053] Step 1, modular assembly: First, the glass pressing plate 2, the storm cover 3 and the main window frame 1 are tightly fitted in sequence by means of movable bolts. These components are modularly designed to facilitate quick assembly and maintenance. The reinforcing inner ring 22 is integrated between the glass pressing plate 2 and the inner side of the pressing plate mounting outer ring 21. When the storm cover 3 and the glass pressing plate 2 are covered, the fixed wedge block 23 and the movable wedge block 31 are used to achieve preliminary positioning to ensure that the components can be stably docked before tightening;

[0054] Step 2, sealing and locking: The sealing effect between the glass platen 2 and the storm cover 3 is ensured by the sealing ring and the elastic pad 2201 to prevent water and air leakage. When the storm cover 3 and the glass platen 2 are fastened, the movable plugging bolt 43 is controlled to descend to seal the circular assembly groove 2200, and the movable block 31 and the fixed block 23 that are in contact with each other are locked from top to bottom;

[0055] Step 3: Stable lifting control: During the lifting process of the movable plugging member 43, the limit column 434 and the spring 433 are used to maintain its stability and weaken the shaking caused by the external force;

[0056] Step 4: gas control and locking enhancement: air is introduced into the air flow converter 44 through the gas adapter joint, and gas is injected into the bottom of the piston member 45 through the lower air pipe 441. At this time, the bottom of the piston member 45 is pushed upward by the gas. At this time, the magnetic sleeve installed on the piston member 45 moves synchronously, and the magnetic sleeve is electrically connected to the magnetic sliding ring 464, and the two are two magnetic poles of opposite sexes that attract each other. While the magnetic sleeve moves upward, the magnetic sliding ring 464 moves on the surface of the center limit straight tube 42. At this time, the fixed gear rod 2 463 moves upward, driving the rotating gear 462 to rotate, and at this time, the fixed gear rod 1 461 is adapted to mesh with the rotating gear 462, and the fixed gear rod 1 461 moves downward, and its lower end portion is formed by the locking groove 2 310 opened on the movable wedge block 31 and penetrates the inner wall of the locking groove 1 230, so as to realize the secondary locking after the initial limit between the fixed wedge block 23 and the movable wedge block 31;

[0057] Step 5, unlocking and pressure balance: when the storm cover needs to be opened, the cover tight fitting mechanism 4 is unlocked by controlling the gas injection and discharge, and the gas is injected into the central limit straight pipe 42 through the upper air pipe 442, and the gas enters the upper position of the piston plate. When the upper part of the piston plate is compressed by the gas, the piston member 45 is lowered as a whole, thus driving the fixed gear rod 2 463 to descend. At this time, the fixed gear rod 1 461 drives the limit edge rod 46 and the movable blocking bolt 43 to rise as a whole. When the bottom position of the fixed gear rod 2 463 is blocked by the limit lining rod 410 and cannot be lowered, At this time, the fixed gear rod 461 rises, releasing the restrictions on the fixed wedge block 23 and the movable wedge block 31, and the excess gas will compress the T-shaped pressure block 4501 set on the piston plate, so that the T-shaped pressure block 4501 moves downward under the pressure of the gas, and the elastic wire 4502 is squeezed. At this time, the gas enters the channel of the gas injection pipe 4503 through the air inlet 4500, and the gas is then discharged to the outside through the top position of the circular sealing plate. In this way, air is slowly injected between the inner cavity of the glass pressure plate 2 and the storm cover 3 to balance the internal and external pressures and ensure that the storm cover can be opened smoothly.
