[0002] On ships, the electromagnetic suction structure of fire doors is an important device for controlling the closing of fire doors. Fire doors are used on ships to isolate fires and prevent the spread of fire. The electromagnetic suction structure of fire doors is a device that can control the closing of fire doors, usually consisting of an electromagnetic magnet and a control system. When a fire occurs, the control system will trigger the electromagnetic magnet to generate magnetic force to attract the fire door, thereby ensuring that the fire door can be quickly closed, preventing the spread of fire and protecting the safety of the ship and crew. The electromagnetic suction device of the fire door usually uses a fixed support bracket to adapt to the limited angle after the door is opened.

DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The present application embodiment discloses a concealed adjustable distance fire door electromagnetic suction device. Figure 1 , Figure 2 A hidden adjustable distance fire door electromagnetic suction device includes a fixed base 1, the fixed base 1 includes a fixed part 11 close to the door side and an action part 12 away from the door side, the fixed part 11 is fixedly connected to the door, and the fixed part 11 is fixedly connected to the action part 12. The fixed base 1 is horizontally arranged and detachably fixed to the door through the fixed part 11. When it needs to be adjusted according to different requirements, the height of the fixed base 1 can be disassembled and adjusted by bolts.

[0028] Reference Figure 2 , Figure 3An angle adjustment component is provided on the fixed base 1, and the angle adjustment component can be adjusted according to the opening and closing angle of the door. A first adsorption component 2 is provided at the end of the angle adjustment component, and a second adsorption component 3 is provided on the wall plate 4. The first adsorption component 2 can be relatively adsorbed with the second adsorption component 3, so as to fix the opening and closing angle of the door. The second adsorption component 3 is detachably connected to the wall plate 4, and the height of the second adsorption component 3 is the same as that of the fixed base 1, so as to facilitate the relative adsorption and fixation of the first adsorption component 2 and the second adsorption component 3.

[0029] The angle adjustment assembly includes a first synchronization rod 5 and a second synchronization rod 6 located at both ends of the fixed base 1. The first synchronization rod 5 and the second synchronization rod 6 are arranged in parallel. The first synchronization rod 5 is located at one end of the fixed base 1 close to the hinge point of the door, and the second synchronization rod 6 is located at one end of the fixed base 1 away from the hinge point of the door. The first synchronization rod 5 is rotatably connected to the fixed base 1, and the second synchronization rod 6 is rotatably connected to the fixed base 1. The end of the first synchronization rod 5 away from the fixed base 1 extends from the side wall of the door, so that the end of the first synchronization rod 5 abuts against the wall where the door is located.

[0030] A first transmission gear 13 is rotatably connected to the fixed base 1 at a position relative to the first synchronization rod 5, and the first transmission rod gear is fixedly connected to the end of the first synchronization rod 5. A second transmission gear 14 is rotatably connected to the fixed base 1 at a position relative to the second synchronization rod 6, and the second rotation gear is fixedly connected to the end of the second synchronization rod 6. A transmission chain 15 is sleeved on the outer sides of the first transmission gear 13 and the second transmission gear 14, and the transmission chain 15 is meshed with the first transmission gear 13, and the transmission chain 15 is meshed with the second transmission gear 14.

[0031] When the first synchronization rod 5 rotates relative to the fixed base 1, the first synchronization rod 5 drives the first transmission gear 13 to rotate, and the first transmission gear 13 drives the first chain to rotate, and then the first chain synchronously drives the second transmission gear 14 to rotate, so that the second transmission gear 14 finally drives the second synchronization rod 6 to rotate, and the rotation direction and rotation angle of the first synchronization rod 5 and the second synchronization rod 6 are the same.

[0032] A spring 16 is fixedly connected to one side of the second synchronization rod 6 close to the first synchronization rod 5, one end of the spring 16 is fixedly connected to the second synchronization rod 6, and the other end of the spring 16 is fixedly connected to the fixed base 1. When the spring 16 is in a free state, the spring 16 pulls the second synchronization rod 6 to retract, so that the second synchronization rod 6 overlaps with the fixed base 1, and the second synchronization rod 6 drives the first synchronization rod 5 to be set in parallel with the setting direction of the fixed base 1.

[0033] The ends of the first synchronization rod 5 and the second synchronization rod 6 facing away from the fixed base 1 are both arc-shaped structures, so that the first synchronization rod 5 can reduce the possibility of getting stuck when it abuts against the wall. The end of the second synchronization rod 6 facing away from the fixed base 1 is provided with a first adsorption member 2, and the first adsorption member 2 is rotatably connected to the second synchronization rod 6. In some embodiments, the first adsorption member 2 is an iron-absorbing seat plate 21, and the iron-absorbing seat plate 21 includes a connecting portion 211 close to one end of the second synchronization rod 6 and an adsorption portion 212 facing away from one end of the second synchronization rod 6, the connecting portion 211 is rotatably connected to the second synchronization rod 6, the connecting portion 211 and the adsorption portion 212 are fixedly connected, and the adsorption effective area of ​​the end of the adsorption portion 212 facing away from the connecting portion 211 is larger than the area of ​​the connecting portion 211.

[0034] In some embodiments, the second adsorption component 3 can be selected as an electromagnetic suction 31 arranged opposite to the wall panel 4. The electromagnetic suction 31 is fixedly connected to a matching seat plate 32 on one side close to the first adsorption component 2. The matching seat plate 32 is fixed to the first adsorption component 2 by the electromagnetic suction 31.

[0035] Reference Figure 3 , Figure 4 The fixed base 1 is arranged on the door, and when in the initial state, the first synchronization rod 5 is parallel to the fixed base 1, and the end of the first synchronization rod 5 away from the fixed base 1 extends from the side wall of the door, and the end of the first synchronization rod 5 away from the fixed base 1 abuts against the wall where the door is located. The second adsorption member 3 is located on a side wall adjacent to the vertical side of the wall where the door is located. When the door is opened, the door rotates 90°, and the door drives the fixed base 1 to rotate. Due to the limitation of the wall where the door is located, the first synchronization rod 5 does not rotate, and then the fixed base 1 and the first synchronization rod 5 rotate relative to each other, driving the second synchronization rod 6 and the fixed base 1 to rotate, and then the angle between the first synchronization rod 5 and the fixed base 1 is the same as the angle between the second synchronization rod 6 and the fixed base 1, and the first adsorption member 2 located on the second synchronization rod 6 is opposite to the second adsorption member 3, and the first adsorption member 2 and the second adsorption member 3 are adsorbed and fixed.
