Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to an embedded hinged door. Background Art

[0002] The cabin doors of civil ships and military vessels have certain pressure-resistant watertightness, airtightness, and fireproof requirements. Most of the current cabin doors are installed with hinges, that is, one side of the door leaf is assembled with the door frame through hinges. According to the door leaf opening method and sealing requirements, the hinge is generally installed on the side surface of the door leaf and the door frame, and the external hinge is inevitably exposed to the outside. On the one hand, the protruding shape affects the overall appearance, and the hinge is easily eroded by wind and rain, and the service life is short; on the other hand, the general cabin door is heavy, and the hinge does not have a reliable limiting function. After a long time of use, the door body is easy to sink, affecting the sealing effect. Utility Model Content

[0031] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0032] See also Figures 1 to 6 As shown, this preferred embodiment provides a buried hinged door, including a door frame 1 and a door leaf 2, wherein the door frame 1 is fixed to the outer wall of the hull, and one side of the door leaf 2 is connected to the door frame 1 via a hinge 3.

[0033] Among them, the hinge component 3 includes a first mounting seat 31, a second mounting seat 32, a first connecting rod 33, a second connecting rod 34, a third connecting rod 35 and a fourth connecting rod 36. A cavity 11 is provided on the door frame 1 at the mounting position corresponding to the hinge component 3. The first mounting seat 31 is fixed in the cavity 11, and the second mounting seat 32 is fixed to the side of the door leaf 2. One end of the first connecting rod 33 and one end of the second connecting rod 34 are hinged to each other, and the other end of the first connecting rod 33 is hinged to the first mounting seat 31, and the other end of the second connecting rod 34 is hinged to the second mounting seat 32. One end of the third connecting rod 35 and one end of the fourth connecting rod 36 are hinged to each other, and the other end of the third connecting rod 35 is hinged to the second mounting seat 32, and the other end of the fourth connecting rod 36 is hinged to the first mounting seat 31. The middle part of the second connecting rod 34 is hinged to the middle part of the fourth connecting rod 36. Specifically, each fixing point is fastened by bolts, and each hinge is assembled by a pin shaft.

[0034] When the door is closed, the door leaf 2 is engaged with the door frame 1, and the hinge 3 is completely buried in the cavity 11;

[0035] When the door is in the open state, the door leaf 2 rotates relative to the door frame 1 , and a portion of the hinge 3 extends out of the cavity 11 .

[0036] Therefore, the embedded hinged door is designed with a hinge 3 of an internal shape, which ensures that the door leaf 2 can be opened and closed reliably, and at the same time, the service life of the hinge 3 is increased, and the door leaf 2 can be opened smoothly to 180° ( Figure 6 When closed, it can be better embedded in the outer wall of the hull, improving the integrity of the appearance and ensuring reliable sealing.

[0037] As an optional solution, the door leaf 2 is made of a composite plate, which includes a carbon fiber layer 21 on both sides, and a PET filler 22 is arranged between the two carbon fiber layers 21. In addition, the door frame 1 can also be made of this composite plate. The composite plate made of carbon fiber and high-strength PET material can reduce the weight of the entire door by about 50% compared with a conventional steel door of the same size, reduce the pressure on the hinge 3, and have sufficient hardness, strength, wear resistance, and corrosion resistance.

[0038] As an optional solution, the outdoor side surface of the door frame 1 and the outdoor side surface of the door leaf 2 are flush with the surface of the outer wall of the hull. Due to the structure of the embedded hinge 3, there is no protrusion of any parts on the outer surface of the door leaf 2, so that the door leaf 2, the door frame 1 and the outer wall of the hull can be better designed as one body, and the integrity is better.

[0039] As an optional solution, a convex edge 23 is provided on the door leaf 2 at the installation position corresponding to the hinge 3. When the door is closed, the convex edge 23 is matched with the notch of the cavity 11 on the door frame 1, thereby sealing the cavity 11. Since the hinge 3 needs to be extended out of the cavity 11 and retracted into the cavity 11, a notch on the door frame 1 is inevitable, but designing the convex edge 23 on the door leaf 2 can reduce the size of the notch, especially when the door is closed, the convex edge 23 can fill the notch, thereby preventing wind and rain from invading the cavity 11 and protecting the hinge 3.

[0040] As an optional solution, a step edge 12 is provided on the door frame 1, and a circle of sealing strip 24 is provided on the edge of the door leaf 2. A sealing lip 25 is raised on the sealing strip 24, and the sealing lip 25 is in contact and sealed with the step edge 12, thereby ensuring the pressure-resistant, watertight and airtight performance of the cabin door.

[0041] As an optional solution, a plurality of locking buckles 4 are provided on the edge area of ​​the indoor side surface of the door leaf 2, and a locking wedge 5 is provided on the door frame 1 corresponding to each locking buckle 4. The locking buckles 4 are connected by a linkage rod 6, and a switch handle 7 for driving any locking buckle 4 is provided on the indoor side surface of the door leaf 2, so that the locking or unlocking of each locking buckle 4 and the corresponding locking wedge 5 is controlled by the switch handle 7, thereby realizing the locking and unlocking of the door leaf 2.

[0042] Furthermore, the outdoor side surface of the door leaf 2 is provided with a lock hole coaxially linked with the switch handle 7, and a detachable outer handle 8 is provided in the lock hole, and the detachable outer handle 8 can be installed or removed as needed.

[0043] As an optional solution, the indoor side surface and the outdoor side surface of the door leaf 2 are respectively provided with hidden handles 9, so that the appearance of the door leaf 2 is more concise.

[0044] It should be noted that the above-mentioned optional implementation modes can be combined in any combination, and the combined implementation modes all belong to the protection scope of the present utility model.

[0045] It can be seen that the embedded hinged door has a simpler appearance, longer service life, and more convenient operation experience, and has great market promotion and application value.

[0046] The above embodiments are only to illustrate the basic principles and characteristics of the utility model. The utility model is not limited by the above embodiments. Without departing from the spirit and scope of the utility model, the utility model has various changes and modifications, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
