Description

Technical Field

[0001] The invention belongs to the technical field of ship facilities, and in particular relates to a hatch cover shutter structure for ships. Background Art

[0002] Ships are a common means of transport that can sail or carry out transportation or operations in water. Due to the limitations of the aquatic environment, the cabins of ships are usually required to have windows that can be opened for ventilation, while also ensuring excellent sealing when necessary. There are many structures in the industry that have shutters equipped with window covers. Although these structures can meet the functions of ventilation and sealing, they often require manual flipping of the window covers and manual locking or unlocking of the window covers, which is time-consuming and labor-intensive, and very inconvenient.

[0003] In the existing technology, such as the "A Hatch Cover Device for Ships" disclosed in Chinese Invention Patent Authorization Announcement No. CN103832544B, the hatch cover device for ships includes: a hatch cover, which is a rectangular plate; a hatch frame, which is a rectangular frame to support the hatch cover; a hatch hinge, which is located on the upper side of the hatch cover and the hatch frame and can rotate the hatch cover relative to the hatch frame; an opening protrusion, which protrudes laterally from the left side or right side of the hatch cover and rotates forward in conjunction with the opening action of the hatch cover; and a side guide bar, which is a plate extended in the upward and downward directions, the lower end of the side guide bar can be rotatably coupled to the hatch frame, and a long hole-shaped guide hole is formed along the side guide bar, the upper part of the guide hole is further extended rearward to form a support step, and the guide hole is combined with the opening protrusion to guide the opening and closing action of the hatch cover and fix the open state of the hatch cover. Although this technical solution can open automatically and can automatically lock and unlock, its automatic opening angle depends on the torsion of the torsion spring. In addition, since the side guide strips lack positioning in the automatic opening state, the degree of automatic opening of the hatch cover varies, and the opening angle of the window cover cannot be effectively controlled.

[0004] In view of the above problems, it is necessary to design a ship hatch cover shutter structure that is simple in structure, low in cost, can stably reach the pre-opening angle and can position the pre-opening position. To this end, the applicant has cleverly designed this technical solution. Summary of the Invention

[0010] In another specific embodiment of the present invention, the left and right sides of the window frame respectively form a support plate hinge shaft hinged to the support plate, and the left and right sides of the window cover respectively form a window cover sliding shaft passing through the guide positioning groove.

[0022] A venetian blind is arranged in the window frame 1 . The venetian blind is in an inclined state and is arranged in the window frame 1 at intervals up and down.

[0025] The left and right sides of the window frame 1 are respectively formed with a support plate hinge shaft 12 hinged to the support plate 3, and the left and right sides of the window cover 2 are respectively formed with a window cover sliding shaft 22 passing through the guide positioning groove 32.

[0026] A blocking piece 221 is sleeved on one end of the window cover sliding shaft 22 passing through the guide positioning slot 32 and is fixed by a set of nuts 222.

[0027] Please refer to Figure 1 and Figure 3 The aforementioned guide positioning groove 32 includes a closing positioning groove 321, a pre-opening guide groove 322 connected to the closing positioning groove 321, a pre-opening positioning groove 323 connected to the pre-opening guide groove 322, an opening guide groove 324 connected to the pre-opening positioning groove 323 and an opening positioning groove 325 connected to the opening guide groove 324.

[0028] See also Figure 4 Combined with Figure 1 The locking mechanism 4 includes a locking rod 41, a self-locking mechanism 42 fixed to the window cover 2, and a locking rod seat 43 fixed to the window cover 2 and located above the self-locking mechanism 42. One end of the locking rod 41 passes upward through the locking rod seat 43 and is bent to form a locking rod bent foot 411. The self-locking mechanism 42 is downwardly formed with a lock head 421 fixedly connected to the other end of the locking rod 41. The window frame 1 is provided with a lock plate 13 that cooperates with the lock head 421 at a position corresponding to the lock head 421. The lock plate 13 is obliquely downwardly formed with a guide surface 131 toward the side of the lock head 421. The lock plate 13 is provided with a lock that cooperates with the lock head 421. Lock hole 132, the aforementioned lock head 421 slides up and down in the self-locking mechanism 42, and a lock head flange 4211 is formed at the middle part of the aforementioned lock head 421 located in the self-locking mechanism 42, and a lock head baffle 425 is fixed below the aforementioned self-locking mechanism 42, the aforementioned lock head 421 passes through the lock head baffle 425, and the lock head flange 4211 rests on the lock head baffle 425, and a step 423 is formed in the aforementioned self-locking mechanism 42, and a return spring 422 is sleeved on the position of the aforementioned lock head 421 located between the step 423 and the lock head flange 4211, and an oil filling hole 424 for filling oil into the interior is provided on the aforementioned self-locking mechanism 42.

[0029] Continue reading Figures 1 to 5 ,in Figure 3This is a schematic diagram of the structure of the aforementioned window cover 2 and window frame 1 in the closed state. During the closing process, the lock head 421 is pushed by the guide surface 131, compressing the return spring 422 until the lock head 421 is inserted into the lock hole 132. At this time, the support plate hinge axis 12 is located in the closing positioning groove 321, and the support plate 3 is vertically upward. If the support plate 3 accidentally tilts forward, the connection between the closing positioning groove 321 and the opening guide groove 322 will abut against the window cover sliding shaft 22 to maintain the position. When the window cover 2 needs to be opened, the operator pushes the locking rod bent foot 411 upwards, so that the locking rod 41 pulls the lock head 421 out of cooperation with the lock hole 132 after overcoming the elastic force of the return spring 422. At this time, the window cover 2 is rotated open around the hinge shaft 7 under the action of the torsion spring 6. Under normal circumstances, the torsion force of the torsion spring 6 can make the window cover 2 open 30 degrees and reach the pre-opening state. The support plate 3 is pushed forward by the window cover sliding shaft 22 to rotate around the support plate hinge shaft 12. The window cover sliding shaft 22 slides along the opening guide groove 322 until it slides into the pre-opening positioning groove 323. At this time, if the window cover 2 wants to continue to open, it is necessary to overcome the gravity of the support plate 3 itself and make the window cover sliding shaft 22 slide along the opening guide groove 324. The torsion force of the torsion spring 6 is not enough to overcome the gravity of the support plate 3. The window cover 2 is locked and unlocked when the lock is unlocked, and the lock is unlocked when the lock is unlocked. The lock is unlocked when the lock is unlocked. When the torsion spring 6 is used for too long and the torque is reduced or the torque of the torsion spring 6 is too large, the torsion spring adjustment portion 61 is adjusted to cooperate with the adjustment slots 51 at different positions on the adjustment disk 5, so that the torsion stability of the torsion spring 6 can be maintained for a long time, thereby greatly extending the service life of the shutter structure.

It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
