Abstract
Description
Technical Field
[0001] This invention relates to the field of hinge installation technology, specifically to a wooden door hinge and its installation structure. Background Technology
[0002] A hinge, also known as a hinge, is a mechanical device that connects two solid objects (most commonly doors, windows, and covers) and allows them to rotate within a limited angle about a fixed axis. When installing right-angled concealed hinges onto wooden doors, workers typically insert screws through holes in the hinges and into the door to install them. However, because the diameter of the holes in the hinges and the screws are not perfectly matched, there is a gap. When the worker inserts the screw, its position within the hole can easily shift. This misalignment can cause the screw to exert a lateral pushing force on the hinge during installation, leading to misalignment and making it difficult for the other half of the hinge to fit properly against the door. This affects the hinge's installation strength and stability during subsequent use. Summary of the Invention
[0003] The purpose of this invention is to provide a wooden door hinge and its installation structure to solve the problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a wooden door hinge, comprising two main bodies and a wooden door, and further comprising: The adjustment mechanism is installed inside the main body. When the wooden door is deformed, the adjustment mechanism can be adjusted to reset the wooden door, so as to realize the normal use of the wooden door and quick adjustment.
[0005] Furthermore, the main body includes: The limiting component is installed on the side wall of the main body and can freely adjust the wooden door when in operation.
[0006] Furthermore, the adjustment mechanism includes a support frame disposed inside the limiting component, and the adjustment mechanism also includes: A sliding component is installed on the side wall of the load-bearing frame; The connecting component is installed on the side wall of the sliding component. The connecting component can increase the gripping force of the wooden door on the screw when the screw is drilled.
[0007] Furthermore, the limiting component includes a square frame fixedly connected to the side of the main body near the wooden door, and the front of the square frame has a straight groove. Adjusting bolts are provided on the left side and front of the square frame, with the front adjusting bolt slidably connected to the inside of the straight groove. The adjusting bolt on the left slides through into the inside of the square frame, and a nut is threaded onto the outer surface of the adjusting bolt.
[0008] Furthermore, the support frame is slidably connected inside the square frame, and the left side of the support frame is slidably connected to one of the adjusting bolts; Among them, the adjusting bolt on the front slides through into the interior of the load-bearing frame.
[0009] Furthermore, the sliding assembly includes a connecting block that is slidably connected inside the support frame, and the front side of the connecting block is slidably connected to another adjusting bolt; The side of the load-bearing frame closest to the wooden door is rotatably connected to two bolts, and the outer surface of the top bolt two is threaded with two nuts. The end of the bolt two away from the connecting block is slidably connected to a connecting shaft. Among them, the side of nut two closest to the connecting shaft is rotatably connected to the side wall of the connecting shaft.
[0010] Furthermore, the connecting assembly includes two connecting plates disposed on the outer surface of the connecting shaft, one connecting plate being fixedly connected to the outer surface of the connecting shaft, and the other connecting plate being fixedly connected to the side wall of the connecting shaft.
[0011] Furthermore, the side wall of the connecting plate is provided with several mounting holes, which are arranged at equal intervals, and the side of the connecting plate near the wooden door is provided with several rectangular grooves. The mounting hole corresponds to the center of rectangular groove one, and rectangular groove two is provided on both the front and back of rectangular groove one.
[0012] Furthermore, a wooden door hinge installation structure, suitable for a wooden door hinge, includes a sliding shaft slidably connected between two rectangular slots, the sidewall of the sliding shaft being provided with two spring plates, and the sliding shaft further includes: The elastic component is installed on the outer surface of the auxiliary mechanism; The spring plate slides through to the inner wall of the rectangular groove on the side away from the mounting hole.
[0013] Furthermore, the elastic component includes a spring sheet fixedly connected to the outer surface of the sliding shaft, and the side wall of the spring sheet is provided with a flared groove; Two diamond-shaped plates are fixedly connected to the side of the spring clip closest to the wooden door, and two right-angled plates are fixedly connected to the side of the spring clip away from the diamond-shaped plates; The right-angle plate is set at an angle, and several cylindrical grooves are opened on the side wall of the right-angle plate.
[0014] The present invention has the following beneficial effects: 1. This invention, by restricting the center position of the screw in the mounting hole, can reduce the situation where, when the screw is subsequently drilled into the wooden door through the mounting hole, the eccentricity of the screw's position within the mounting hole causes a lateral pushing force on the connecting plate through the inner wall of the mounting hole, resulting in a deviation in the installation position of the connecting plate on the wooden door and making it difficult for the other connecting plate to fully fit with the wooden door. This improves the accuracy of the connecting plate installation on the wooden door and also enhances the stability of the wooden door during use.
[0015] 2. The present invention, by forming barbs, can reduce the situation where the screw and the hole during drilling expand due to the movement of the wooden door when it is deformed and moved downward outdoors, and the screw is unable to form a stable fastening force between the connecting block and the wooden door. In this way, the wooden door can improve the gripping force of the screw, while improving the stability and installation strength of the connecting block and the wooden door during installation.
[0016] 3. In this invention, the screw's drilling path and perpendicularity can be controlled by the flared groove between the two spring plates to drill perpendicularly into the wooden door. At this time, the flared groove on the two spring plates can ensure that the screw is in a straight state during drilling, thereby reducing the possibility of uneven pressure between the screw and the connecting block due to tilted drilling. This ensures stable screw drilling and reduces the possibility of movement caused by the angle between the connecting block and the wooden door due to screw tilt. This further improves the installation strength between the device and the wooden door and improves the flatness during installation.
[0017] 4. This invention, by blocking the screw through the gap between the two right-angle plates, can reduce the possibility of the screw retraction between the spring and the wooden door during long-term opening, closing and vibration of the wooden door. This further ensures the stability of the hinge and the wooden door installation by screws, while also enhancing the connection strength and positional stability of the screws between the connecting plate and the wooden door, thereby further improving installation efficiency.
[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Please see Figure 1 - Figure 9 As shown, the present invention is a wooden door hinge, comprising two main bodies 1 and a wooden door 4, and further comprising: Adjustment mechanism 2 is installed inside the main body 1. When the wooden door 4 is deformed, the adjustment mechanism 2 can be adjusted to reset the wooden door 4, so as to realize the normal use and quick adjustment of the wooden door 4.
[0024] Entity 1 includes: The limiting component 11 is installed on the side wall of the main body 1. When in operation, the limiting component 11 can freely adjust the wooden door 4.
[0025] The adjustment mechanism 2 includes a support frame 201 disposed inside the limiting component 11, and the adjustment mechanism 2 also includes: Sliding component 21 is installed on the side wall of the support frame 201; The connecting component 22 is installed on the side wall of the sliding component 21. The connecting component 22 can increase the gripping force of the screws on the wooden door 4 when the screws are drilled in.
[0026] The limiting component 11 includes a square frame 111 fixedly connected to the side of the main body 1 near the wooden door 4, and the front of the square frame 111 has a straight groove 112. Adjusting bolts 113 are provided on the left side and the front side of the square frame 111. The adjusting bolt 113 on the front side is slidably connected to the inside of the straight groove 112. The adjusting bolt 113 on the left slides through the inside of the square frame 111. The outer surface of the adjusting bolt 113 is threaded with a nut. When the wooden door 4 needs to be adjusted forward and backward, the operator can turn the nut on the front adjusting bolt 113. At this time, the front adjusting bolt 113 will drive the connecting shaft 212, the connecting plate 221 and the wooden door 4 to adjust forward and backward through the connecting block 211.
[0027] The support frame 201 is slidably connected inside the square frame 111, and the left side of the support frame 201 is slidably connected to one of the adjusting bolts 113; Among them, the adjusting bolt 113 on the front slides through into the interior of the bearing frame 201.
[0028] The sliding assembly 21 includes a connecting block 211 that is slidably connected inside the support frame 201, and the front side of the connecting block 211 is slidably connected to another adjusting bolt 113; The support frame 201 is rotatably connected to the side of the wooden door 4 with bolt 2, and the outer surface of the top bolt 2 is threaded with nut 2. The end of bolt 2 away from the connecting block 211 is slidably connected to the connecting shaft 212. Among them, the nut 2 is rotatably connected to the side wall of the connecting shaft 212 on the side of the connecting shaft 212. When the wooden door 4 needs to be adjusted left and right, the worker rotates the nut on the left adjusting bolt 113. At this time, the left adjusting bolt 113 can drive the bearing frame 201, connecting block 211, connecting shaft 212, connecting plate 221 and wooden door 4 to be adjusted left and right when the nut is rotated.
[0029] The connecting assembly 22 includes two connecting plates 221 disposed on the outer surface of the connecting shaft 212. One connecting plate 221 is fixedly connected to the outer surface of the connecting shaft 212, and the other connecting plate 221 is fixedly connected to the side wall of the connecting shaft 212. When the height of the wooden door 4 needs to be adjusted up and down, the worker can first clamp the rotating bolt 2 inside the connecting block 211 and then turn the nut 2 on the surface of the bolt 2 with a wrench. At this time, the rotation of the nut 2 can drive the wooden door 4 to adjust its height up and down through the connecting shaft 212 and the connecting plate 221 on the connecting shaft 212.
[0030] The side wall of the connecting plate 221 is provided with a number of mounting holes 222, which are arranged at equal intervals. The side of the connecting plate 221 near the wooden door 4 is provided with a number of rectangular grooves 223. The mounting hole 222 corresponds to the middle of the rectangular groove 223. The rectangular groove 224 is provided on both the front and back sides of the rectangular groove 223.
[0031] A wooden door hinge installation structure, applicable to a wooden door hinge, includes a sliding shaft 3 slidably connected between two rectangular slots 224, the side wall of the sliding shaft 3 is provided with two spring plates 301, and the sliding shaft 3 further includes: Elastic component 31 is mounted on the outer surface of auxiliary mechanism 3; The spring plate 301 slides through to the inner wall of the rectangular groove 224 on the side away from the mounting hole 222.
[0032] The elastic component 31 includes a spring piece 311 fixedly connected to the outer surface of the sliding shaft 3, and the side wall of the spring piece 311 is provided with a flared groove. Two diamond-shaped plates 313 are fixedly connected to the side of the spring piece 311 closest to the wooden door 4, and two right-angle plates 312 are fixedly connected to the side of the spring piece 311 away from the diamond-shaped plates 313. The right-angle plate 312 is set at an angle, and several cylindrical grooves are opened on the side wall of the right-angle plate 312. When the spring piece 311 is pressed into the wooden door 4, the diamond plate 313 on the side wall of the spring piece 311 will be pressed into the wooden door at the same time.
[0033] In use, the wooden door 4 is first placed between the four connecting plates 221. Then, the workers drill screws into the wooden door 4 through the mounting holes 222. At this time, the screws can fix the wooden door 4 to the connecting plates 221. Then, the workers connect the main body 1 to the ground and the wall with bolts. This completes the installation of the hinge with the wooden door 4 so that the wooden door 4 can be opened and closed normally.
[0034] When the wooden door 4 deforms and loses height after being exposed to wind and sun outdoors for a long time, the staff can use a wrench to turn the nuts on the two adjusting bolts 113 in the direction of the required adjustment to adjust the angle so that the wooden door 4 can work normally. It should be noted that when the wooden door 4 needs to be adjusted forward and backward, the staff can turn the nut on the front adjusting bolt 113. At this time, the front adjusting bolt 113 will drive the connecting shaft 212, the connecting plate 221 and the wooden door 4 to adjust forward and backward through the connecting block 211. When it is necessary to adjust the wooden door 4 left and right, the staff will turn the nut on the left adjustment bolt 113. At this time, the left adjustment bolt 113 can drive the load-bearing frame 201, connecting block 211, connecting shaft 212, connecting plate 221 and wooden door 4 to adjust left and right when the nut is turned. When the height of the wooden door 4 needs to be adjusted, the worker can first clamp the rotating bolt 2 inside the connecting block 211 and then turn the nut 2 on the surface of the bolt 2 with a wrench. At this time, the rotation of the nut 2 can drive the wooden door 4 to adjust its height through the connecting shaft 212 and the connecting plate 221 on the connecting shaft 212. By adjusting the wooden door 4 at multiple angles with a wrench, the wooden door 4 can be reset without disassembly when it deforms or decreases in height after working outdoors for a long time. This reduces disassembly and increases the reset speed when adjusting the wooden door 4, improving the speed and convenience of adjusting the wooden door 4, and also improving the practicality of adjusting the wooden door 4.
[0035] When the worker inserts the screw through the mounting hole 222 and installs the connecting plate 221 to the wooden door 4, the tip of the screw will be positioned at the junction of the two spring clips 311 as it enters the mounting hole 222. The worker then gently pushes the screw downwards, generating a pushing force on the two spring clips 311. The two spring clips 311 then slide away from each other around the mounting hole 222. Simultaneously, the tip of the screw gets stuck between the two spring clips 311 and covers the screw surface. At this point, the screw is positioned in the center of the mounting hole 222 and perpendicular to the wooden door 4, thus enabling… By restricting the screw to the center position of the mounting hole 222, the eccentricity of the screw's position within the mounting hole 222 when it is subsequently drilled into the wooden door 4 can be reduced. This eccentricity can cause the screw to exert a lateral pushing force on the connecting plate 221 through the inner wall of the mounting hole 222, resulting in a deviation in the installation position of the connecting plate 221 on the wooden door 4. Consequently, it can prevent the connecting plate 221 from fully fitting into the wooden door 4. This improves the accuracy of the connecting plate 221's installation on the wooden door 4 and also enhances the stability of the wooden door 4 during use.
[0036] When the screw is stuck between the two spring clips 311, the threads on the outer surface of the screw's tip will engage with the cylindrical groove on the outer surface of the right-angle plate 312. Then, when the worker drills the screw into the wooden door 4 through the center of the mounting hole 222, the threads on the screw tip and surface will interact with the cylindrical groove on the right-angle plate 312. Because the spring clips 311 have a certain rigidity and bending deformation force, as the screw is drilled into the wooden door 4, the downward rotation and compression of the screw will cause the ends of the two spring clips 311, along with the right-angle plate 312, to be drawn into and pressed into the wooden door 4, forming two opposing spring clips around the screw hole. The auxiliary channel is called the spring plate 311. Simultaneously, when the spring plate 311 is pressed into the wooden door 4, the diamond-shaped plate 313 on the side wall of the spring plate 311 is pressed into the wooden door along with it. Then, as the screw continues to drill in, the diamond-shaped plate 313 is blocked by the inner wall of the hole created during drilling, making it difficult to continue its straight downward movement. At this point, the outer edge of the diamond-shaped plate 313 is forced to bend towards the spring plate 311 and fit against its side wall. The tip of the bent diamond-shaped plate 313 forms a barb-like structure between the hole in the wooden door 4 and the spring plate 311, embedding itself within the hole and restricting any possible sliding between the wooden door 4, the spring plate 311, and the screw, as shown in the attached diagram. Figure 9 As shown in the diagram, the formation of barbs can reduce the situation where the screw and the hole during drilling enlarge due to the movement of the wooden door 4 when it is deformed and moved downward outdoors, making it difficult for the screw to form a stable fastening force between the connecting block 211 and the wooden door 4. This can improve the gripping force of the wooden door 4 on the screw, while also improving the stability and installation strength of the connecting block 211 and the wooden door 4 during installation.
[0037] When the screw drills into the wooden door 4 between the two spring plates 311, it will drill downwards within the flared grooves on the two spring plates 311. As the screw continues to drill downwards, its drilling path and verticality are controlled by the flared grooves between the two spring plates 311, allowing it to drill perpendicularly to the wooden door 4. At this time, the flared grooves on the two spring plates 311 ensure that the screw remains straight during drilling, thereby reducing the risk of uneven pressure between the screw and the connecting block 211 due to tilted drilling. This ensures stable screw drilling and reduces the possibility of movement caused by the angle between the connecting block 211 and the wooden door 4 due to screw tilt. This further improves the installation strength between the device and the wooden door 4 and enhances the flatness during installation.
[0038] When the spring plate 311, along with the right-angle plate 312, is pressed into the interior of the wooden door 4 along with the screw, a triangular gap is formed between the two right-angle plates 312. As the screw continues to drill downwards, it will be positioned within this gap. The engagement of the screw's outer surface threads with the cylindrical groove will drive the spring plate 311 to continue drilling until it slides to its limit and can no longer be pressed in. At this point, the triangular gap between the two right-angle plates 312 will create an upward resistance on the screw's threaded surface. This resistance reduces the likelihood of the screw retracting between the spring plate 311 and the wooden door 4 during prolonged opening, closing, and vibration. This further ensures the stability of the hinge installation with the wooden door 4 and enhances the connection strength and positional stability of the screw between the connecting plate 221 and the wooden door 4, thereby improving installation efficiency.
