Description

Technical Field

[0001] This application relates to the field of anti-pry structure technology, specifically an anti-pry structure for the hinge end of an entrance door. Background Technology

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can be made of movable components or foldable materials. Hinges are mainly installed on doors and windows. Entrance doors are installed inside the door frame via hinges. Conventional designs have flat hinge edges, which creates gaps between the door leaf and the door frame. Intruders can use this gap to forcibly cut several hinges and then use tools to pry open the door leaf from the hinge side without a key. This does not provide good anti-theft protection, so anti-pry structures are needed to protect the entrance door hinges.

[0003] For example, the patent with publication number CN202322004455.8 specifically discloses an anti-pry structure for the hinge end of an entrance door, including an installation frame, an entrance door body, an anti-pry hinge, a first cavity, a threaded rod, a threaded sleeve, a fixing rod, and a second cavity. By rotating the knob, the threaded rod and the threaded sleeve drive the fixing rod to move. The fixing rod drives the baffle to move to the right through the slider and abuts in the slot. The baffle can block the gaps in the door frame to prevent outdoor dust and insects from entering the room through the gaps.

[0004] However, although the aforementioned device blocks the gap between the entrance door and the door frame by moving the baffle to prevent mosquitoes from entering the room, the screw that controls the movement of the baffle is located on the outside of the entrance door, i.e., outdoors. This allows a vandal to operate the screw from the outside, thereby moving the baffle and exposing the gap between the entrance door and the door frame. Therefore, the baffle in the aforementioned device is not very effective in protecting the hinges and cannot effectively protect the hinges of the entrance door, thus reducing the security of the entrance door.

[0005] Therefore, it is necessary to provide an anti-pry structure for the hinge end of the entrance door to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an anti-pry structure for the hinge end of an entrance door, which solves the problem that the screw of the control baffle is set outdoors, making it difficult for the baffle to only block mosquitoes and insects, but not to effectively protect the hinge.

[0008] The technical solution adopted by this application to solve its technical problem is: an anti-pry structure for the hinge end of an entrance door, including a door frame;

[0009] A rectangular groove, which is formed in the door frame;

[0010] The entrance door is installed on the door frame;

[0011] Anti-pry mechanism, which includes three cavities opened in the door frame, wherein trapezoidal blocks are slidably connected in the cavities;

[0012] The surface of the door frame is slidably connected with three sliding rods, one end of which is fixedly connected to a trapezoidal block;

[0013] A baffle is slidably connected to the inner wall of the rectangular groove. Three slots are provided on the surface of the baffle. The size of the trapezoidal block and the slots are matched, and the baffle is in close contact with the surface of the entrance door.

[0014] Wherein: the rectangular groove is adapted to the size of the baffle, the baffle is inserted into the rectangular groove, the sliding rod is pushed, and the trapezoidal block is inserted into the slot, which restricts the movement of the baffle and completes the fixation of the baffle. The baffle can cover the gap between the door frame and the entrance door.

[0015] Furthermore, the anti-pry mechanism also includes a ladder block fixedly connected to one side of the baffle. The ladder block and the trapezoidal block have the same structure, and the baffle is made of stainless steel.

[0016] Furthermore, a cylinder is fixedly connected to the other side of the baffle.

[0017] Furthermore, the surface of the baffle is provided with an outer groove.

[0018] Furthermore, a connecting plate is fixedly connected to one end of each of the three sliding rods that is close to each other, and a pull rod is fixedly connected to the surface of the connecting plate.

[0019] Furthermore, a spring is fitted onto the arc surface of the slide rod, and the two ends of the spring are fixedly connected to the door frame and the connecting plate, respectively.

[0020] The beneficial effects of this application are as follows: The anti-pry structure of the hinge end of the entrance door provided by this application, by setting an anti-pry mechanism, through the setting of spring, sliding rod, trapezoidal block and baffle, can block the gap between the entrance door body and the door frame, avoiding the situation where vandals damage the hinge body through the gap, facilitating the replacement of the baffle, thereby improving the security of the entrance door. At the same time, the baffle and rubber strip work together to block mosquitoes and insects.

[0021] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figures 1-3As shown, this application provides an anti-pry structure for the hinge end of an entrance door, including a door frame 1, the door frame 1 including an entrance door body 2 located inside the door frame 1, a hinge body 11 is provided between the door frame 1 and the entrance door body 2, the door frame 1 and the entrance door body 2 are rotatably connected through the hinge body 11, a rectangular groove 12 is provided on the door frame 1, a handle 21 is installed on the entrance door body 2, and a rubber strip 22 is fixedly connected to one side of the entrance door body 2;

[0033] The entrance door 2 can be opened by the handle 21, while the rubber strip 22 can seal the gap between the entrance door 2 and the door frame 1, reducing the chance of mosquitoes entering the room.

[0034] like Figures 1-5 As shown, an anti-pry mechanism 3 is installed on the door frame 1 and the entrance door 2. The anti-pry mechanism 3 includes three cavities 301 opened on the door frame 1, and trapezoidal blocks 305 are slidably connected in the cavities 301; three sliding rods 302 are slidably connected to the surface of the door frame 1, and one end of the sliding rods 302 is fixedly connected to the trapezoidal blocks 305; a baffle 307 is slidably connected to the inner wall of the rectangular groove 12, and three slots 308 are opened on the surface of the baffle 307. The size of the trapezoidal blocks 305 and the slots 308 are matched, and the baffle 307 is in close contact with the surface of the entrance door 2.

[0035] The rectangular groove 12 is suitable for the size of the baffle 307. The baffle 307 is inserted into the rectangular groove 12, and the slide rod 302 is pushed to drive the trapezoidal block 305 into the slot 308, which restricts the movement of the baffle 307 and completes the fixation of the baffle 307. The baffle 307 can cover the gap between the door frame 1 and the entrance door 2.

[0036] like Figures 3-5 As shown, the anti-pry mechanism 3 also includes a step block 309 fixedly connected to one side of the baffle 307. The step block 309 and the trapezoidal block 305 have the same structure. The baffle 307 is a stainless steel plate. A cylinder 310 is fixedly connected to the other side of the baffle 307. An outer groove 311 is opened on the surface of the baffle 307.

[0037] The design of the step block 309 facilitates the compression of the trapezoidal block 305 by the baffle 307 when it is inserted into the rectangular slot 12, causing it to move away from the baffle 307. Since the baffle 307 and the entrance door 2 are in close contact, and with the addition of the cylinder 310, it makes it difficult for a violent person to insert an object between the entrance door 2 and the baffle 307, thereby preventing them from performing acts of damage such as prying or tearing the baffle 307.

[0038] like Figures 3-5 As shown, a connecting plate 303 is fixedly connected to one end of the three sliding rods 302 that are close to each other. A pull rod 304 is fixedly connected to the surface of the connecting plate 303. A spring 306 is sleeved on the arc surface of the sliding rod 302. The two ends of the spring 306 are fixedly connected to the door frame 1 and the connecting plate 303 respectively.

[0039] When maintenance or replacement of the baffle 307 is required, first turn the entrance door away from the baffle 307, then pull the lever 304 to move the slide bar 302 on the connecting plate 303, thereby moving the trapezoidal block 305 away from the slot 308. At this time, the user can insert his / her finger into the outer groove 311 to easily remove the baffle 307.

[0040] Working principle:

[0041] The door frame 1 is installed at the entrance of the house. Then, the side of the baffle 307 with the outer groove 311 faces the entrance door 2, and the end with the step block 309 is inserted into the rectangular groove 12. As the step block 309 moves, it gradually comes into contact with the trapezoidal block 305, which can compress the trapezoidal block 305 to shrink and drive the spring 306 to extend. When the slot 308 reaches the trapezoidal block 305, the trapezoidal block 305 loses the compression of the step block 309 and is inserted into the slot 308 under the pull of the spring 306, which can fix the baffle 307. At this time, the baffle 307 can cover the gap between the door frame 1 and the entrance door 2, preventing the violent person from damaging the hinge body 11 through the gap.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
