Description

Technical Field

[0001] This utility model relates to the field of armored door technology, specifically to an armored door that is easy to assemble and disassemble. Background Technology

[0002] Armored doors are special doors designed for high-strength protection. They adopt a multi-layered composite structure, usually with steel or alloy as the frame and filled with impact-resistant materials, which can effectively resist external damage. The door frame and door leaf are reinforced and equipped with hinges and a multi-point locking system, which greatly improves the ability to resist prying and cutting. These doors not only have excellent security performance, but also take into account practical functions such as sound insulation and heat insulation. They are often used in places that require strict security, such as financial institutions, important warehouses, and high-end residences, and are an important barrier for building security.

[0003] When installing existing armored doors with hinges, the entire door body usually needs to be lifted to a certain height so that the hinge holes of the door leaf are aligned with the hinge axis, and then slowly lowered to complete the connection. Because armored doors use heavy metal materials and reinforced structures, they are quite heavy, and it is almost impossible for a single person to operate them independently. Multiple installers are usually required to work together. During the lifting process, it is necessary not only to maintain the balance of the door body, but also to accurately align the hinge position. If you are not careful, the door leaf may tilt or slip due to the center of gravity shift, which increases the installation difficulty and safety hazards, and has a significant impact on construction efficiency.

[0004] In conclusion, to improve the installation efficiency of armored doors and reduce construction difficulty, it is necessary to solve the problem of difficulty in alignment and lifting caused by their excessive weight, so as to make the installation process more labor-saving and precise, thereby reducing manpower consumption and safety risks, and improving the overall construction quality.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] Refer to the instruction manual appendix Figures 1 to 5 An armored door that is easy to assemble and disassemble includes a door frame 1, multiple fixing plates 2 fixed on the door frame 1, positioning sleeves 3 installed on the fixing plates 2, two sliding grooves 4 opened on the positioning sleeves 3, an arc plate 5 slidably connected inside the sliding grooves 4, a guide component for positioning provided at the bottom of the arc plate 5, a connecting shaft 7 rotatably connected inside the positioning sleeve 3, a lubrication component provided on the inner wall of the positioning sleeve 3, a fastening mechanism for fixing provided on the outer side of the two arc plates 5, a reset component provided on the side of the arc plate 5, an installation component provided on the connecting shaft 7, and a door panel 12 adapted to the door frame 1 connected to the installation component.

[0024] It should be noted that the sliding of the arc plate 5 within the groove 4 of the positioning sleeve 3 and the rotation of the connecting shaft 7 enable the flexible opening and closing of the door panel 12 relative to the door frame 1. The guide component ensures the precise sliding trajectory of the arc plate 5, the lubrication component reduces movement resistance, the fastening mechanism reliably locks the two arc plates 5, the reset component provides an automatic reset function, and the installation component enables the door panel 12 to function. The installation component enables the quick connection and separation of the door panel 12 and the connecting shaft 7. The overall design significantly simplifies the installation and disassembly process of the armored door, and is especially convenient for the position adjustment and maintenance of the door panel 12.

[0025] Refer to the instruction manual appendix Figure 1 , Figure 4 and Figure 5 The guide assembly includes a guide groove 61 formed on the bottom surface of the slide 4 and a guide strip 62 fixed to the bottom of the arc plate 5. The guide strip 62 is adapted to the guide groove 61 and is slidably connected to the guide groove 61.

[0026] It should be noted that the guide strip 62 and the guide groove 61 limit the direction of movement of the arc plate 5 in the slide groove 4, ensuring that it can only slide along a predetermined straight trajectory, preventing deviation or jamming, and providing a basis for the smooth and precise movement of the door panel 12.

[0027] Refer to the instruction manual appendix Figures 2 to 4 The lubrication assembly includes multiple oil injection holes 81 opened on the top of the positioning sleeve 3 and multiple oil grooves 82 opened on the inner wall of the positioning sleeve 3, with the oil injection holes 81 connected to the corresponding oil grooves 82.

[0028] It should be noted that the oil injection hole 81 facilitates the injection of lubricant into the contact area between the inner wall of the positioning sleeve 3 and the connecting shaft 7, and the lubricant flows into the oil groove 82 to form a lubricant delivery channel, effectively reducing the frictional resistance of the movement, improving the service life of the components and the smoothness of the door opening and closing.

[0029] Refer to the instruction manual appendix Figure 1 , Figures 3 to 5 The fastening mechanism includes a snap-fit ​​assembly disposed on the side of the arc plate 5 and a fixing assembly disposed on the outside of the arc plate 5. The snap-fit ​​assembly is used to snap the two arc plates 5 together, and the fixing assembly is used to fix the two arc plates 5.

[0030] It should be noted that the fastening mechanism achieves the initial positioning and pre-connection of the two curved plates 5 through the locking component, and then the fastening force is applied by the fixing component to firmly lock the two curved plates 5 together, so as to ensure the overall rigidity and stability of the connection part of the door panel 12.

[0031] Refer to the instruction manual appendix Figure 5 The locking assembly includes a fixing rod 91 fixed to one side of an arc-shaped plate 5, a locking block 92 fixed to the end of the fixing rod 91, and a locking groove opened on the other side of the arc-shaped plate 5, wherein the locking block 92 is adapted to the locking groove.

[0032] It should be noted that after the two curved plates 5 are joined together, the locking block 92 will be embedded in the corresponding slot, which can quickly achieve the initial alignment and temporary fixation of the two curved plates 5, providing convenience and a foundation for the subsequent operation of fastening components.

[0033] Refer to the instruction manual appendix Figures 3 to 5 The fixing assembly includes fixing strips 93 disposed on the outer sides of the two arc-shaped plates 5 and fixing bolts 94 connected to the fixing strips 93. The fixing strips 93 are fixedly connected to the arc-shaped plates 5 by the fixing bolts 94.

[0034] It should be noted that by tightening the fixing bolts 94, the fixing strips 93 are used to position and connect the two arc-shaped plates 5, ensuring the reliability of the connection.

[0035] Refer to the instruction manual appendix Figures 2 to 5The reset assembly includes a fixed base 101 fixed inside the slide 4 and a spring 102 fixed to the side of the arc plate 5, with the end of the spring 102 fixedly connected to the fixed base 101.

[0036] It should be noted that when the external force applied to the arc plate 5 is removed, the arc plate 5 can be automatically pulled back to its initial position in the slide groove 4, thereby opening the front opening of the positioning sleeve 3 to facilitate the removal of the connecting shaft 7.

[0037] Refer to the instruction manual appendix Figure 1 and Figure 2 The installation components include a connecting arm 111 fixed on the connecting shaft 7, a connecting plate 112 fixed at the end of the connecting arm 111, and a positioning screw 113 provided on the connecting plate 112. The connecting plate 112 is fixedly connected to the door panel 12 by the positioning screw 113.

[0038] It should be noted that the door panel 12 is fastened to the connecting plate 112 by the positioning screw 113, and the connecting plate 112, the connecting arm 111, and the connecting shaft 7 form a whole, thereby realizing the rotation and opening of the door panel 12.

[0039] Working principle: When installing door panel 12, the operator first places the connecting shaft 7 into the positioning sleeve 3. At this time, the two arc-shaped plates 5 are slid along the slide groove 4 towards the opening of the positioning sleeve 3, while ensuring that the guide strip 62 at the bottom of the arc-shaped plate 5 always slides within the guide groove 61 on the bottom surface of the slide groove 4 to ensure linear movement. When the two arc-shaped plates 5 slide to a complete close, the locking block 92 at the end of the fixing rod 91 on one arc-shaped plate 5 will automatically embed into the locking groove on the side of the other arc-shaped plate 5, achieving initial positioning. Then, the fixing strip 93 is covered on the outside of the two arc-shaped plates 5 and tightened with the fixing bolt 94, so that the two arc-shaped plates are fully closed. Plate 5 tightly hugs the connecting shaft 7 and locks in position. At this time, the door panel 12 can rotate within the positioning sleeve 3 through the connecting shaft 7 to open and close. During the opening and closing process, the lubricant injected through the oil injection hole 81 at the top of the positioning sleeve 3 flows into the oil groove 82 on the inner wall of the positioning sleeve 3 to lubricate the contact surface between the connecting shaft 7 and the positioning sleeve 3. When it is necessary to disassemble the door panel 12, loosen the fixing bolt 94 and remove the fixing strip 93. The two arc-shaped plates 5 automatically slide back to the initial position under the action of the spring 102. The front opening of the positioning sleeve 3 is opened, and the connecting shaft 7, together with the connecting arm 111, the connecting plate 112 and the door panel 12 fixed thereon, can be taken out as a whole.
