Abstract
Description
Technical Field
[0001] The present application relates to ship cabin maintenance, and in particular, to an inspection door system and a ship cabin. Background Art
[0002] The cables in the cabin are usually arranged in the cabin wall panels or shelf panels. With the increase in equipment maintenance needs, cables or electrical components need to be inspected and maintained regularly. Therefore, inspection doors are widely used as an important means of equipment maintenance.
[0003] Hinge-type inspection doors are fixed to the inspection door frame through hinges and hinges, which has become a common design method. Due to the characteristics of hinges, the inspection door can only be opened in one direction. This feature meets the requirements of space layout to a certain extent. However, it also brings new challenges. Specifically, since the inspection door can only be opened in one direction, it becomes very inconvenient to maintain the cable pipeline in the opposite direction, especially when the cable pipeline is complex and dense, it is difficult for maintenance personnel to carry out effective maintenance work.
[0004] In addition, the length of the hinge directly affects the opening and closing distance of the inspection door. A shorter hinge length may prevent large tools from entering the inspection area smoothly, thus affecting maintenance efficiency and quality.
[0005] Therefore, there is an urgent need to provide an inspection door system and a cabin to solve the problems existing in the prior art to a certain extent. Summary of the invention
[0006] The purpose of the present application is to provide an inspection door system and a cabin, which can increase the serviceable space of the inspection door to a certain extent, and facilitate the inspection and maintenance of the internal lines of the cabin.
[0007] In order to achieve the above-mentioned objectives, in a first aspect, the present invention provides an inspection door system, comprising a door body, a door frame, a locking assembly and a limiting assembly; the door frame is formed with an installation space, the door body is correspondingly arranged in the installation space, the locking assembly and the limiting assembly are connected to the door body and are relatively arranged; the door frame is formed with a first inner edge portion at a position corresponding to the locking assembly, and a second inner edge portion is formed at a position corresponding to the limiting assembly; the locking assembly comprises a lock tongue, the first inner edge portion is located between the lock tongue and the inner side surface of the door body, and the lock tongue can rotate relative to the door body; the limiting assembly comprises a limiting hook, and the second inner edge portion can be inserted between the limiting hook and the inner side surface of the door body.
[0008] In an optional embodiment, the limiting hook includes a connecting section, a transition section, a limiting section and a abutting section; the connecting section is connected to the inner side surface of the door body, the transition section is located between the limiting section and the connecting section, so that the limiting section and the inner side surface of the door body form an accommodating gap, the abutting section is arranged perpendicular to the transition section, and the abutting section is connected to one end of the transition section away from the connecting section, and the end surface of the abutting section away from the transition section can abut against the second inner edge portion.
[0009] In an optional embodiment, the limiting assembly further includes a connecting piece, and the connecting piece passes through the connecting section and is connected to the door body.
[0010] In an optional embodiment, the transition section is arranged perpendicular to the door body.
[0011] In an optional embodiment, the transition section is arranged to be inclined, and an angle between a side of the transition section facing the second inner edge portion and an inner side surface of the door body is an acute angle.
[0012] In an optional embodiment, the transition section is arranged to be inclined, and an angle between a side of the transition section facing the second inner edge portion and an inner side surface of the door body is an obtuse angle.
[0013] In an optional embodiment, the locking assembly also includes a main body and a lock core, the main body passes through the door body along the thickness direction of the door body, the lock core is arranged in the main body and can rotate relative to the main body, one end of the lock core is connected to the lock tongue, and the cross-section of the other end is a polygonal structure.
[0014] In an optional embodiment, a resilient member is provided between the first inner edge and the door body, and when the locking tongue abuts against the first inner edge, the resilient member is compressed, so that the door body has a force to move away from the first inner edge.
[0015] In an optional embodiment, the door frame is a rectangular frame, the installation space is rectangular, the door body is a rectangular plate structure, the first inner edge portion and the second inner edge portion are arranged in parallel, and the first inner edge portion corresponds to the top of the door body, and the second inner edge portion corresponds to the bottom of the door body.
[0016] In a second aspect, the present invention provides a cabin, comprising the inspection door system in the aforementioned embodiment.
[0017] Through the above technical solution, the door body can be completely detached from the door frame. Therefore, on the one hand, the traditional method of connecting the door body and the door frame through hinges is eliminated, thereby eliminating the hinge structure and saving costs. On the other hand, since the door body can be completely detached from the door frame, the opening and closing angles of the traditional door body will not be affected by the hinges, nor will it be blocked by other external structures in the cabin, affecting the size of the opening and closing angles of the door body. This makes maintenance more convenient and can easily deal with situations such as reversely arranged cables.
[0018] The present application realizes the detachable door body and door frame through a locking assembly and a limiting assembly. Since the locking assembly and the limiting assembly in the present application are arranged relative to each other, and the door frame is provided with a first inner edge portion at a position corresponding to the locking assembly, and a second inner edge portion is provided at a position corresponding to the limiting assembly, and the first inner edge portion is located between the lock tongue of the locking assembly and the inner side surface of the door body, and the second inner edge portion is located between the limiting assembly and the inner side surface of the door body. The lock tongue can rotate relative to the door body, therefore, during installation, the gap between the limiting hook and the inner side surface of the door body is first aligned with the second inner edge portion, and when the second inner edge portion is inserted into the gap between the limiting hook and the door body, the door body is pushed to move the locking assembly in a direction close to the first inner edge portion.
[0019] When the door body is fitted with the first inner edge, the lock tongue is rotated by a key so that the lock tongue is lifted and abuts against the first inner edge, thereby locking the door body. Accordingly, the door body and the door frame can be stably connected through the common limiting of the lock tongue and the limiting hook, thereby completing the installation of the door body.
[0020] When the door needs to be disassembled, the lock tongue is rotated with a key so that the lock tongue falls down and separates from the first inner edge, thereby unlocking the door corresponding to the first inner edge. After the lock tongue is unlocked, the door can be pulled outward. Since the limit hook is still in a plugged state with the second inner edge, the door can tilt slightly outward but will not fall off. The operator can hold the edge of the door and pull it out, so that the limit hook gradually separates from the second inner edge, and then the door can be completely removed from the door frame, so that the hollow of the door frame is completely exposed, which is convenient for maintenance personnel to inspect and maintain cables or other internal structures.
[0021] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0031] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0032] like Figure 1-Figure 3 As shown, the present invention provides an inspection door system, including a door body 2, a door frame, a locking assembly and a limiting assembly; the door frame is formed with an installation space, the door body 2 is correspondingly arranged in the installation space, the locking assembly and the limiting assembly are connected to the door body 2 and are relatively arranged; the door frame is formed with a first inner edge portion 101 at a position corresponding to the locking assembly, and a second inner edge portion 102 is formed at a position corresponding to the limiting assembly; the locking assembly includes a lock tongue 3, the first inner edge portion 101 is located between the lock tongue 3 and the inner side surface of the door body 2, and the lock tongue 3 can rotate relative to the door body 2; the limiting assembly includes a limiting hook 6, and the second inner edge portion 102 can be inserted between the limiting hook 6 and the inner side surface of the door body 2.
[0033] Compared with the prior art, the access door system provided by this application has the following advantages:
[0034] The inspection door system provided in the present application can provide an installation space for the door body 2 through the door frame. Accordingly, the door frame is a hollow structure, and the hollow part needs to be covered by the door body 2 to form an overall inspection door system, so as to shield the inspection position, and when inspection and maintenance are required, the door body 2 can be removed from the door frame to thereby realize inspection of the inside of the inspection position.
[0035] It can be understood that since the door body 2 provided in the present application can be completely detached from the door frame, on the one hand, the traditional method of connecting the door body 2 and the door frame through hinges is eliminated, thereby eliminating the hinge structure and saving costs. On the other hand, since the door body 2 can be completely detached from the door frame, the opening and closing angles of the traditional door body 2 will not be affected by the hinges, nor will it be blocked by other external structures in the cabin, affecting the size of the opening and closing angles of the door body 2. This makes maintenance more convenient and can easily deal with situations such as reversely arranged cables.
[0036] The present application realizes the detachable door body 2 and door frame by means of a locking assembly and a limiting assembly. Since the locking assembly and the limiting assembly in the present application are arranged relative to each other, and the door frame is provided with a first inner edge portion 101 at a position corresponding to the locking assembly, and a second inner edge portion 102 at a position corresponding to the limiting assembly, and the first inner edge portion 101 is located between the lock tongue 3 of the locking assembly and the inner side surface of the door body 2, and the second inner edge portion 102 is located between the limiting assembly and the inner side surface of the door body 2. The lock tongue 3 can rotate relative to the door body 2. Therefore, during installation, the gap between the limiting hook 6 and the inner side surface of the door body 2 is first aligned with the second inner edge portion 102. After the second inner edge portion 102 is inserted into the gap between the limiting hook 6 and the door body 2, the door body 2 is pushed to move the locking assembly in a direction close to the first inner edge portion 101.
[0037] When the door body 2 is fitted with the first inner edge 101, the lock tongue 3 is rotated by a key so that the lock tongue 3 is lifted and abuts against the first inner edge 101, thereby locking the door body 2. Accordingly, through the common limiting of the lock tongue 3 and the limiting hook 6, the door body 2 can be stably connected to the door frame, thereby completing the installation of the door body 2.
[0038] When the door body 2 needs to be disassembled, the lock tongue 3 is rotated with a key so that the lock tongue 3 falls and separates from the first inner edge 101, thereby unlocking the door body 2 corresponding to the first inner edge 101. After the lock tongue 3 is unlocked, the door body 2 can be pulled outward. Since the limit hook 6 is still in a plugged state with the second inner edge 102, the door body 2 can tilt outward slightly but will not fall off. The operator can hold the edge of the door body 2 to pull the door body 2 out, so that the limit hook 6 gradually separates from the second inner edge 102, and then the door body 2 can be completely disassembled from the door frame, so that the hollowing of the door frame is completely exposed, which is convenient for maintenance personnel to inspect and maintain cables or other internal structures.
[0039] In an optional embodiment, the limiting hook 6 includes a connecting section 601, a transition section 602, a limiting section 603 and abutting section 604; the connecting section 601 is connected to the inner side surface of the door body 2, and the transition section 602 is located between the limiting section 603 and the connecting section 601, so that the limiting section 603 and the inner side surface of the door body 2 form a accommodating gap, and the abutting section 604 is arranged perpendicular to the transition section 602, and the abutting section 604 is connected to one end of the transition section 602 away from the connecting section 601, and the end face of the abutting section 604 away from the transition section 602 can abut against the second inner edge 102.
[0040] The connection between the limit hook 6 and the door body 2 can be achieved through the connecting section 601, and the connection method can be bonding or welding. Preferably, the limit assembly provided in the present application also includes a connecting member 7, and the connecting member 7 is a structure such as a bolt, a screw, or a rivet. The connecting member 7 can pass through the connecting section 601 and connect to the door body 2, thereby fixing the overall limit hook 6 on the inner side of the door body 2.
[0041] Correspondingly, the transition section 602 can form an accommodation gap between the limiting section 603 and the door body 2 to accommodate the second inner edge portion 102. When the second inner edge portion 102 is inserted into the accommodation gap between the transition section 602 and the door body 2, the lower half of the door body 2 can be limited, so that the door body 2 cannot be pulled outward in the thickness direction.
[0042] The abutting section 604 formed perpendicular to the limiting section 603 can abut against the second inner edge portion 102 after assembly, thereby ensuring the tightness of the overall limiting hook 6 and preventing the door body 2 from shaking to a certain extent.
[0043] Based on the above structure, the present application provides three implementations of the transition section 602, one of which is as follows: Figure 4 As shown, the transition section 602 is arranged perpendicular to the door body 2.
[0044] Another Figure 3 As shown, the transition section 602 is arranged at an incline, and the angle between the side of the transition section 602 facing the second inner edge portion 102 and the inner side surface of the door body 2 is an acute angle.
[0045] The third type Figure 5 As shown, the transition section 602 is inclined, and the angle between the side of the transition section 602 facing the second inner edge portion 102 and the inner side surface of the door body 2 is an obtuse angle.
[0046] It can be understood that, whether it is vertically arranged, at an acute angle, or at an obtuse angle, the door body 2 can be tilted outward during the disassembly process. In practical applications, it is preferred to adopt Figure 3 The visible structural form, i.e., the transition section 602 forms an acute angle with the door body 2, can not only allow the door body 2 to have a sufficient rotation angle when disassembled, but also ensure that the position of the door body 2 is fixed after installation to avoid movement and shaking.
[0047] In an optional embodiment, if Figure 1-Figure 3 As shown, the locking assembly in the present application also includes a main body 4 and a lock core 5. The main body 4 penetrates the door body 2 along the thickness direction of the door body 2. The lock core 5 is arranged in the main body 4 and can rotate relative to the main body 4. One end of the lock core 5 is connected to the lock tongue 3, and the cross-section of the other end is a polygonal structure.
[0048] The end away from the lock tongue 3 is polygonal, which can be distinguished from the existing conventional key, so that unauthorized persons cannot rotate the lock tongue 3 through other structures, thereby ensuring the stability of the door body 2 when locked.
[0049] In an optional embodiment, a resilient member is provided between the first inner edge 101 and the door body 2 , and when the lock tongue 3 abuts against the first inner edge 101 , the resilient member is compressed, so that the door body 2 has a force to move away from the first inner edge 101 .
[0050] The rebound component in the present application can be a structure such as a spring, an elastic column or a press-type rebounder, and the rebound component can be arranged on both the side of the first inner edge 101 facing the door body 2 and the side of the door body 2 facing the first inner edge 101, or can be arranged alone on the side of the first inner edge 101 facing the door body 2 or the side of the door body 2 facing the first inner edge 101.
[0051] It can be understood that the rebound component set between the door body 2 and the first inner edge portion 101 can not only play a role in buffering and shock absorption to a certain extent, but also be pressurized after the door body 2 is installed in place, so that when the lock tongue 3 is unlocked, it can rebound, realize the automatic pop-up of the upper part of the door body 2, and improve the disassembly efficiency.
[0052] When the resilient member adopts a push-type rebounder, after unlocking the lock tongue 3, the maintenance personnel need to press the door body 2 again, so that the push-type rebounder pops out and pushes the door body 2 outward.
[0053] Preferably, the door frame in the present application is a rectangular frame, the installation space is rectangular, the door body 2 is a rectangular plate structure, the first inner edge 101 and the second inner edge 102 are arranged in parallel, and the first inner edge 101 corresponds to the top of the door body 2, and the second inner edge 102 corresponds to the bottom of the door body 2.
[0054] Furthermore, the present invention provides a cabin comprising the inspection door system in the aforementioned embodiment.
[0055] like Figure 1-Figure 3 As shown, the cabin provided in the present application includes a base plate 8, and the base plate 8 can be a wall panel or a shelf panel. The base plate 8 can achieve a stable connection of the door frame 1, and the installation of the door frame 1 can be achieved by fasteners such as bolts.
[0056] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.
[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
