Description

Technical Field

[0001] This utility model relates to the field of threshold component technology, and in particular to an anti-pry and anti-displacement wooden door threshold component. Background Technology

[0002] A threshold is a special component installed at the bottom of a door frame where it meets the ground. Its main function is to prevent rainwater from flowing back in, prevent water from seeping into the room through the gaps at the bottom of the door, and also to block sand and soil to some extent.

[0003] However, most existing thresholds are simple strip structures. To facilitate disassembly, they are mostly directly inserted into the frame in front of the door, lacking anti-pry mechanisms. This allows outsiders to easily pull the threshold away and use tools such as pry bars to pry open the door leaf or lock from the gap at the bottom of the door.

[0004] Therefore, this application proposes an anti-pry and anti-displacement wooden door threshold component. Utility Model Content

[0005] This utility model discloses an anti-pry and anti-displacement wooden door threshold component, which aims to solve the technical problem that existing threshold components lack anti-pry function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pry-proof and displacement-proof wooden door threshold assembly includes a door frame and an L-shaped threshold. Two symmetrical door panels are hinged to the inner wall of the door frame. Door lock assemblies are installed on the front of the two door panels. Mounting plates are fixedly connected to both sides of the L-shaped threshold. Two symmetrical mounting frames are fixedly installed on the front of the door frame, and the inner walls of the mounting frames are adapted to the mounting plates. A reinforcement mechanism is provided between the L-shaped threshold and the door panels.

[0008] The reinforcement mechanism includes two reinforcement grooves respectively opened on the lower surface of the two door panels. The inner top wall of the reinforcement groove is rotatably connected to a threaded rod. The back of the door panel has a rotating opening that extends into the reinforcement groove. The inner wall of the rotating opening is rotatably connected to an operating rod. One end of the operating rod located inside the reinforcement groove and the surface of the threaded rod are both fixedly connected to bevel gears. The surface of the threaded rod is threadedly connected to a threaded insert. The inner bottom wall of the L-shaped door sill has a slot that matches the threaded insert.

[0009] In a preferred embodiment, the two bevel gears mesh with each other, and the operating lever is connected to the threaded rod via the bevel gears.

[0010] In a preferred embodiment, guide sliders are provided on both sides of the threaded insert, and guide grooves for the guide sliders to slide are provided on both sides of the inner wall of the reinforcing groove.

[0011] By setting a guide slider, the threaded cylinder can move up and down in a directional manner through the rotation of the threaded rod under the guidance of the guide slider.

[0012] In a preferred embodiment, a protective layer is embedded on the front of the L-shaped threshold, and the protective layer is a high-strength metal material such as steel sheet.

[0013] By installing a protective layer, the damage to the threshold caused by people stepping on it can be reduced.

[0014] In a preferred embodiment, the lower surface of the L-shaped threshold is provided with a mounting groove, and a sealing strip is embedded inside the mounting groove.

[0015] By installing sealing strips, the sealing performance of the L-shaped threshold after it overlaps with the ground can be improved.

[0016] In a preferred embodiment, two symmetrical door handles are fixedly installed on both the front and back of the door panel.

[0017] As can be seen from the above, the anti-pry and anti-displacement wooden door threshold component provided by this utility model has the following technical effects.

[0018] Firstly, the L-shaped threshold is inserted between the two assembly frames using the mounting plate until the sealing strip touches the ground. At this point, the two door panels are closed, so that they are closed above the L-shaped threshold. Because the threshold is L-shaped, it cannot be easily pulled out by outsiders after the door panels are closed, thus preventing them from prying the door open through the gap at the bottom. Furthermore, the protective layer reduces the damage to the threshold when people step on it, thereby increasing the threshold's service life.

[0019] Secondly, rotating the operating lever drives the threaded rod to rotate via the bevel gear. Under the guidance of the guide slider, the threaded insert can move up and down in a directional manner through the rotation of the threaded rod until the threaded insert moves down and is inserted into the slot of the L-shaped threshold. With the limiting and reinforcement of the threaded insert, the firmness of the door panel and the threshold after closing can be improved. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-6 A pry-proof and displacement-proof wooden door threshold assembly includes a door frame 1 and an L-shaped threshold 2. Two symmetrical door panels 3 are hinged to the inner wall of the door frame 1. Door lock assemblies 4 are installed on the front of the two door panels 3. Mounting plates 5 are fixedly connected to both sides of the L-shaped threshold 2. Two symmetrical mounting frames 6 are fixedly installed on the front of the door frame 1, and the inner wall of the mounting frame 6 is adapted to the mounting plates 5. A reinforcement mechanism is provided between the L-shaped threshold 2 and the door panels 3.

[0029] Two symmetrical door handles 15 are fixedly installed on both the front and back of the door panel 3.

[0030] The reinforcement mechanism includes two reinforcement grooves respectively opened on the lower surface of the two door panels 3. The inner top wall of the reinforcement groove is rotatably connected to a threaded rod 7. The back of the door panel 3 is provided with a rotating opening that extends into the reinforcement groove. The inner wall of the rotating opening is rotatably connected to an operating rod 8. One end of the operating rod 8 located inside the reinforcement groove is fixedly connected to a bevel gear 9 on the surface of the threaded rod 7. The surface of the threaded rod 7 is threadedly connected to a threaded insert 10. The inner bottom wall of the L-shaped threshold 2 is provided with a slot 11 that matches the threaded insert 10.

[0031] Two bevel gears 9 mesh with each other, and the operating lever 8 is connected to the threaded rod 7 via the bevel gears 9.

[0032] Guide sliders 12 are provided on both sides of the threaded insert 10, and guide grooves for sliding of the guide sliders 12 are provided on both sides of the inner wall of the reinforcing groove. Under the guidance of the guide sliders 12, the threaded insert 10 can move up and down in a directional manner by rotating the threaded rod 7.

[0033] Reference Figure 2 and Figure 3 In a preferred embodiment, a protective layer 13 is embedded on the front of the L-shaped threshold 2. The protective layer 13 is made of high-strength metal materials such as steel sheets. By setting the protective layer 13, the damage to the threshold caused by people stepping on it can be reduced.

[0034] The lower surface of the L-shaped threshold 2 is provided with an installation groove, and a sealing strip 14 is embedded inside the installation groove. The sealing strip 14 can improve the sealing performance of the L-shaped threshold after it overlaps with the ground.

[0035] Working principle: In use, the L-shaped threshold 2 is inserted between the two assembly frames 6 through the assembly plate 5 until the sealing strip 14 is in contact with the ground. At this time, the two door panels 3 are closed, so that the two door panels 3 are closed above the L-shaped threshold 2. Because the threshold is L-shaped, after the door panels 3 are closed, outsiders cannot easily pull the threshold away, and thus cannot pry the door through the gap at the bottom of the door. At the same time, rotating the operating lever 8 drives the threaded rod 7 to rotate through the bevel gear 9. Under the guidance of the guide slider 12, the threaded cylinder 10 can move up and down in a directional direction through the rotation of the threaded rod 7 until the threaded cylinder 10 moves down and is inserted into the slot 11 of the L-shaped threshold 2. Under the limiting and reinforcement of the threaded cylinder 10, the firmness of the door panel 3 and the threshold after closing can be improved.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
