[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 - Figure 5 The present invention provides an anti-intrusion door and window hinge, which includes a wall 100, a hinge unit 200 provided in the wall 100 for self-locking when subjected to external pressure and preventing bad people from intruding, a door 300 connected to one side of the hinge unit 200, and a first sliding groove 101 provided in the wall 100 to provide the door 300 with movement space when subjected to pushing force;

[0028] The hinge unit 200 includes a first hinge 202 slidably disposed in the first slide groove 101. A first self-locking mechanism and a second self-locking mechanism are installed on one side of the first hinge 202 to prevent intrusion by damaging the hinge unit 200. A second hinge 201 is hinged to one side of the first hinge 202. The second hinge 201 is connected to the door body 300. The door body 300 opens and closes through the second hinge 201. The wall 100 is provided with a second slide groove 102. A slide rail box 103 is provided in the second slide groove 102. A slide rod 204 is slidably connected in the slide rail box 103. The slide rod 204 is not directly slidably connected to the second slide groove 102 here to avoid the wall from having too much friction on the slide rod 204, which would affect the realization of the self-locking function.

[0029] The second self-locking mechanism includes a blocking member 205 fixedly connected to one end of the slide rod 204. The blocking member 205 is cylindrical and made of steel. The blocking member 205 has an internal thread, and a threaded rod 206 is threadedly connected to the internal thread of the blocking member 205. One end of the threaded rod 206 is designed as a gear and is made of steel. A rack 203 is fixedly connected to one side of the first hinge 202. The position of the rack 203 changes with the position of the first hinge 202. The rack 203 meshes with the gear at one end of the threaded rod 206. The slide rod 204 is used to prevent the blocking member 205 from rotating, ensuring that the blocking member 205 can make linear motion when the threaded rod 206 rotates, so that the self-locking function of the second self-locking mechanism can be realized.

[0030] The first self-locking mechanism includes a self-locking slot formed in the wall 100, a self-locking component 207 provided in the slot, the self-locking component 207 having a ring design, a groove 2071 formed around the inner wall of the self-locking component 207, a rotating component 208 fixedly connected to one end of a threaded rod 206, the rotating component 208 passing through the self-locking component 207, a lock head groove 2081 formed around the inside of the rotating component 208, a lock head 2082 and a spring 2083 slidably arranged inside the lock head groove 2081, the spring 2083 being sleeved on the outer wall of the lock head 2082, the spring 2083 being used for the reset of the lock head 2082, the groove 2071 cooperating with the lock head 2082 to realize the self-locking function of the first self-locking mechanism;

[0031] In use, when a person outside the door 300 kicks the door 300 with considerable force, the door 300 experiences a large instantaneous force. The door 300, via the first hinge 202, drives the rack 203 to move towards the other end of the first slide groove 101. The rack 203 meshes with a gear at one end of the threaded rod 206, causing the threaded rod 206 to rotate. The threaded rod 206 then drives the rotating component 208 to rotate. The rotating component 208, through a large centrifugal force, throws the lock head 2082 outside the lock head groove 2081. The lock head 2082 engages with the slot 2071 to achieve self-locking of the first self-locking mechanism. At this time, the second self-locking mechanism does not form a self-lock because the large instantaneous force causes the rotating component 208 to... At the beginning of rotation, the lock head 2082 is thrown to the outside of the lock head groove 2081, locking the rotating part 208 and stopping its rotation. At this time, the second self-locking mechanism serves as a backup protection. When a person outside continuously uses a large force to break it, the first self-locking mechanism is damaged. At this time, under the pushing force on the door 300, the rack 203 drives the threaded rod 206 to rotate. The threaded rod 206 pushes the blocking part 205 to the outside of the first slide groove 101. The blocking part 205 blocks one side of the door 300, causing the person outside to be resisted again, thus effectively consuming the person outside's physical strength and giving the person inside a longer time to prepare for the alarm and self-protection.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
