Description

Technical Field

[0001] This utility model relates to the field of door and window hardware technology, specifically a multi-point locking door frame. Background Technology

[0002] Door frame is an architectural and interior design term referring to the two frames of a door, one inside and one outside. It is also sometimes simply called a door frame. Its main functions are to secure the door leaf, protect wall corners, and provide decoration. It is commonly used in interior design to protect the door from scratches, corrosion, damage, and dirt.

[0003] Currently, mainstream door frame locking systems typically employ a single-point locking mechanism. This means that the lock is installed on the side of the door. When the door is closed, a bolt extends from the middle of the side of the door and inserts into the corresponding keyhole on the side of the door frame to achieve locking. All locking force is concentrated on this single locking point. Since attackers can use the lever principle to concentrate force at the locking point, the bolt is prone to deformation, the keyhole may break, or the door frame may be partially damaged, resulting in significantly insufficient anti-theft security.

[0004] Therefore, this utility model provides a multi-point locking door frame to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a multi-point locking door frame, such as Figure 1 , Figure 2 and Figure 4 As shown, the door frame includes a door frame body 1, a door body 2 rotatably installed inside the door frame body 1, and a locking mechanism disposed inside the door body 2 for fixing the door frame body 1 and the door body 2.

[0027] The locking mechanism includes a movable plate 3 slidably installed inside the door body 2, a rotating plate 4 rotatably installed inside the door body 2, a control rod 5 fixedly installed on one side of the rotating plate 4, a first slide groove 6 opened inside the movable plate 3 for the control rod 5 to slide, a fixed rod 7 fixedly installed on one side of the movable plate 3, a first limit rod 8 fixedly installed inside the door body 2, a lifting plate 9 slidably installed inside the door body 2, an inclined groove 10 and a third slide groove 22 opened inside the lifting plate 9, a first insert 11 fixedly installed on the lifting plate 9, and a second insert 12 fixedly installed on one side of the movable plate 3.

[0028] The side surface of the fixing rod 7 is in contact with the inner wall of the inclined groove 10, the side surface of the first limiting rod 8 is in contact with the inner wall of the third sliding groove 22, the first insert 11 and the second insert 12 both penetrate the door body 2, and the door frame body 1 has a slot for the first insert 11 and the second insert 12 to be inserted.

[0029] When using this door frame, first install the door frame body 1 in a suitable position. Then, push the door body 2 to rotate around the door frame body 1 until the door body 2 is completely closed. After that, start rotating the rotating plate 4. Through the rotation of the rotating plate 4 and the cooperation between the control rod 5, the moving plate 3 slides inside the door body 2. The fixed rod 7 slides along the inner wall of the inclined groove 10. Due to the design of the inclined groove 10, the lifting plate 9 will rise or fall inside the door body 2. At the same time, the first limiting rod 8 will slide in the third sliding groove 22 to play a limiting role. When the door body 2 is closed in place, the first insert 11 and the second insert 12 will be inserted into the slot inside the door frame body 1 at the same time to realize the fixed locking of the door frame body 1 and the door body 2. At this time, the door frame is in a multi-point locking state, which enhances the stability and safety of the door frame.

[0030] Furthermore, to facilitate control of the rotation of the rotating plate 4, such as... Figure 1 , Figure 2 and Figure 5 As shown, a second limiting rod 13 is fixedly connected inside the door body 2, and a second sliding groove 14 is opened inside the movable plate 3.

[0031] The side surface of the second limiting rod 13 is in contact with the inner wall of the second slide groove 14. A handwheel 15 is rotatably connected to one side of the door body 2. The handwheel 15 is fixedly connected to one side of the rotating plate 4 through a rotating shaft.

[0032] When in use, the user can drive the rotating plate 4 to rotate by turning the handwheel 15. Since one side of the rotating plate 4 is fixedly connected to the shaft of the handwheel 15, the rotation of the handwheel 15 will drive the rotating plate 4 to rotate together. At the same time, the second sliding groove 14 inside the moving plate 3 is in contact with the second limiting rod 13 fixedly connected inside the door body 2. This design restricts the moving plate 3 to move only along the direction of the second limiting rod 13, thereby ensuring the stability of the rotating plate 4 during rotation. When the rotating plate 4 rotates, it will drive other components connected to it to perform corresponding actions, such as the control rod 5, thereby realizing the locking or unlocking operation between the door frame body 1 and the door body 2. This design not only makes the operation of the door frame simpler, but also improves the reliability and durability of the door frame.

[0033] It should be noted that, in order to further lock the door frame body 1 and the door body 2, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a fixed frame 16 is fixedly connected inside the door body 2, a latch 17 is fixedly connected to one side of the door frame body 1, a latch 18 is slidably connected inside the fixed frame 16, and a slider 19 is fixedly connected to one side of the latch 18.

[0034] A guide rod 20 is fixedly connected inside the fixed frame 16. A spring 21 is sleeved on the side surface of the guide rod 20. One end of the spring 21 is fixedly connected to the inner wall of one side of the fixed frame 16, and the other end of the spring 21 is fixedly connected to one side of the locking block 18.

[0035] When the door frame is in use, and it is necessary to lock the door frame body 1 and the door body 2, the inclined surface of the locking block 18 fits against the locking rod 17, allowing it to slide along the direction of the guide rod 20. At this time, the spring 21 will be compressed. When the locking block 18 slides to the position corresponding to the locking rod 17, due to the elastic force of the spring 21, the locking block 18 will quickly pop out and lock into the locking rod 17, thereby locking the door frame body 1 and the door body 2. This design not only increases the stability of locking, but also makes the operation more convenient. When unlocking, the user only needs to push the locking block 18 to disengage it from the locking rod 17. The entire locking and unlocking process is smooth and seamless, greatly improving the convenience and safety of the door frame.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
