Description

Technical Field

[0001] This invention relates to the field of wooden door hinge structure technology, specifically an adjustable wooden door hinge structure. Background Technology

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solid objects (such as doors, windows, and covers) and allow them to rotate about an axis. There are three types of hinges: ordinary hinges, spring hinges, and bearing hinges. Ordinary hinges are equipped with ball bearings, have good load-bearing capacity, and open and close smoothly. They are often used for heavier doors. One common problem is that the weight of the wooden door itself is too great. During use, the pressure of the door will be directly applied to the hinges, causing the hinges to be subjected to a downward pressure for a long time, resulting in hinge deformation. This often leads to misalignment of the door frame when closing the door, which requires replacing the hinges and incurring additional economic expenses. To address the above problems, the following solutions are proposed. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an adjustable wooden door hinge structure, including a base, a housing fixedly connected to the top of the base, a sliding shell slidably connected to the inner wall of the housing, and a sliding block slidably connected to the inner wall of the sliding shell, and further including: The support mechanism is rotatably connected to the inner wall of the through hole of the sliding block; The pressure mechanism is fixedly connected to the side wall of the housing; The actuating mechanism is slidably connected to the outer wall of the pressure mechanism; The wooden door is fixed to the door frame by equipment. When the wooden door tilts, the staff can adjust the posture of the wooden door through a pressure mechanism.

[0004] Preferably, the support mechanism includes: The adjusting component is rotatably connected to the inner wall of the through hole of the sliding block; The force-bearing component is slidably connected to the outer wall of the adjusting component; Before use, the bottom base needs to be fixed to the ground and the top base needs to be fixed to the wall.

[0005] Preferably, the pressure mechanism includes: The limiting component is fixedly connected to the side wall of the housing; An auxiliary component is slidably connected to the side wall of the limiting component; The limiting and auxiliary components consist of three sets: one set is fixed to the outer wall of the outer shell to control the sliding of the sliding shell on the inner wall of the outer shell; one set controls the sliding of the sliding block inside the sliding shell; and the last set limits the rotation of the adjusting and force-bearing components.

[0006] Preferably, the driving mechanism includes: The pressure application component is slidably connected to the side wall of the limiting component; A limiting component is fixedly connected to the side wall of the pressure application component; Under normal conditions, the limiting component is restricted by the pressure component, closely attached to the outer wall of the auxiliary component, and restricts the movement of the auxiliary component.

[0007] Preferably, the adjusting assembly includes a rotating column rotatably connected to the inner wall of the sliding block through hole, a hexagonal screw fixedly connected to the top of the rotating column, a threaded rod fixedly connected to the top of the hexagonal screw, and a sliding column rotatably connected to the top of the threaded rod. When it is necessary to adjust the height of the load-bearing component, the worker can use a wrench to turn the hexagonal screw, forcing the hexagonal screw to drive the threaded rod to rotate.

[0008] Preferably, the force-bearing component includes a fixed shell that is slidably connected to the outer wall of the sliding column, a threaded ring that is fixedly connected to the inner wall of the fixed shell, and a fixed plate that is fixedly connected to the side wall of the fixed shell. The inner thread of the threaded ring and the outer thread of the threaded rod are meshed. When the hexagonal screw drives the threaded rod to rotate, the threaded ring will drive the fixed shell to slide up and down along the outer wall of the sliding column.

[0009] Preferably, the limiting component includes a nut fixedly connected to the side wall of the housing, a groove is provided on the side wall of the nut, and a lead screw is threadedly connected to the inner wall of the groove. Each hinge structure has two nuts inside, one fixed to the side wall of the outer shell and the other fixed to the side wall of the sliding shell. The connection position between the threaded ring and the threaded rod is also fixedly equipped with auxiliary components, pressure components and limiting components.

[0010] Preferably, the auxiliary component includes three sliding grooves two formed on the side wall of the lead screw, with a fixing block slidably connected to the inner wall of the three sliding grooves two, and an annular groove formed on the side wall of the nut; The outer walls of the three fixed blocks are slidably connected to the inner wall of the annular groove.

[0011] Preferably, the pressure application component includes a sliding plate slidably connected to the inner wall of the slide groove, an annular plate fixedly connected to the side wall of the sliding plate, and a spring fixedly connected to the side wall of the annular plate. In this design, the end of the spring away from the annular plate is fixedly connected to the side wall of the nut. Under normal conditions, the spring is in a contracted state, forcing the end of the sliding plate to be tightly pressed against the outer wall of the nut.

[0012] Preferably, the limiting component includes a fixing ring fixedly connected to the side wall of the sliding plate, an mounting ring fixedly connected to the side wall of the fixing ring, a plurality of spring plates fixedly connected to the inner wall of the mounting ring, and a tension post fixedly connected to the side wall of the sliding plate. When the spring drives the annular plate and the fixed ring to slide, the fixed ring will cause several spring plates to contact the outer wall of the fixed block, thus restricting the rotation of the fixed block.

[0013] The present invention has the following beneficial effects: (1) This invention addresses the problem of excessive weight of wooden doors, especially when used outdoors, leading to deformation of the hinges after prolonged use. The device incorporates a pressure mechanism and a pushing mechanism. When the door frame deforms due to prolonged hinge use, the operator can adjust the position by twisting three lead screws. Figure 3 As shown, when the screw is turned at position H, the sliding shell is forced to slide slowly along the inner wall of the outer shell, adjusting the left and right position of the rotating column. When the screw is turned at position L, the sliding block is forced to slide along the inner wall of the sliding shell, adjusting the front and back position of the rotating column. When the hexagonal screw is turned, the height of the fixed shell, the fixed plate, and the wooden door is adjusted. Through the application of the above components, the hinge mechanism can adapt to changes in the wooden door, improving the service life of the hinge mechanism. (2) To address the problem of misalignment between the hinge structure and the wooden door, the present invention includes a pressure mechanism and a pushing mechanism inside the device, such as... Figure 11 As shown, under normal conditions, the spring is in a contracted state, which will cause the annular plate, sliding plate, and fixed ring to move closer to the outer shell. At the same time, the mounting ring will cause several spring plates to contact the outer wall of the fixed block. The contacting spring plates will be resisted and tilted outward, presenting a state P. The spring plates on both sides of the P position will restrict the rotation of the fixed block, and the fixed block will restrict the rotation of the screw rod. Similarly, the bottom component of the threaded ring also restricts the rotation of the threaded rod. Through the application of the above components, the phenomenon of the wooden door position deviation caused by the loosening of the internal threaded components due to high-frequency vibration during the opening and closing process is effectively prevented. (3) In the process of adjusting the lead screw, the lead screw will drive three fixed blocks to slide along the inner wall of the annular groove. After the adjustment is completed, it will stop at any position. Then the staff will release the pulling column, so that the spring will drive the annular plate to reset. Finally, the spring plate will contact the outer wall of the fixed block, causing some spring plates to tilt outward. The width of the spring plate is smaller than the width of the fixed block. Through the design of the above components, the fixed block can only drive a single spring plate to tilt outward. If a single fixed block presses two spring plates to tilt outward, the lead screw itself will rotate slightly under the high-frequency vibration of the outside. Finally, the fixed block will be stuck at the bottom of a single spring plate to complete the limiting function and adapt to different adjustment states. (4) This invention utilizes the characteristics of the spring sheet restricting the fixing block. After tilting upward at position P, the distance between the spring sheets on both sides of the fixing block will be wider than the width of the fixing block. This allows a small gap to be reserved on the left and right sides of the fixing block, such as... Figure 11At the position of O, when the hinge structure is subjected to high-frequency vibration, the high-frequency vibration will force the fixing block to reciprocate and rotate a short distance between the two spring plates. Through the application of the above components, the hinge structure is protected in outdoor environments. Even if the hinge rusts due to water accumulation or other reasons, the screw and nut are in a short-distance movement state for a long time, which will greatly reduce the possibility of the screw and nut connection getting stuck.

[0017] 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.

[0018] Example 1, please refer to Figure 1 - Figure 3 The present invention is an adjustable wooden door hinge structure, including a base 13, a housing 14 fixedly connected to the top of the base 13, a sliding shell 15 slidably connected to the inner wall of the housing 14, and a sliding block 16 slidably connected to the inner wall of the sliding shell 15, and further including: Support mechanism 1 is rotatably connected to the inner wall of the through hole of sliding block 16; Pressure mechanism 2 is fixedly connected to the side wall of housing 14; The pushing mechanism 3 is slidably connected to the outer wall of the pressure mechanism 2; The wooden door is fixed to the door frame by the equipment. When the wooden door tilts, the staff can adjust the posture of the wooden door through the pressure mechanism 2.

[0019] Supporting mechanism 1 includes: Adjustment component 11 is rotatably connected to the inner wall of the through hole of sliding block 16; Force-receiving component 12 is slidably connected to the outer wall of adjusting component 11; Before use, the bottom base 13 needs to be fixed to the ground and the top base 13 needs to be fixed to the wall.

[0020] Pressure mechanism 2 includes: Restriction component 21 is fixedly connected to the side wall of housing 14; Auxiliary component 22 is slidably connected to the side wall of limiting component 21; Among them, there are three sets of limiting components 21 and auxiliary components 22. One set is fixed to the outer wall of the outer shell 14 to control the sliding of the sliding shell 15 on the inner wall of the outer shell 14. Another set controls the sliding of the sliding block 16 inside the sliding shell 15. The last set limits the rotation of the adjusting component 11 and the force-bearing component 12.

[0021] The driving body 3 includes: Pressure application component 31 is slidably connected to the side wall of limiting component 21; Limiting component 32 is fixedly connected to the side wall of pressure application component 31; Under normal conditions, the limiting component 32 is restricted by the pressure application component 31, closely adhering to the outer wall of the auxiliary component 22, and restricting the movement of the auxiliary component 22.

[0022] Example 2, please refer to Figure 2 - Figure 11 The present invention is an adjustable wooden door hinge structure. Based on Example 1, the adjustment component 11 includes a rotating column 111 rotatably connected to the inner wall of the through hole of the sliding block 16. A hexagonal screw 112 is fixedly connected to the top of the rotating column 111. A threaded rod 113 is fixedly connected to the top of the hexagonal screw 112. A sliding column 114 is rotatably connected to the top of the threaded rod 113. When it is necessary to adjust the height of the force-bearing component 12, the operator can use a wrench to turn the hexagonal screw 112, forcing the hexagonal screw 112 to drive the threaded rod 113 to rotate.

[0023] The force-bearing component 12 includes a fixed shell 121 that is slidably connected to the outer wall of the sliding column 114, a threaded ring 122 that is fixedly connected to the inner wall of the fixed shell 121, and a fixed plate 123 that is fixedly connected to the side wall of the fixed shell 121. The inner thread of the threaded ring 122 is engaged with the outer thread of the threaded rod 113. When the hexagonal screw 112 drives the threaded rod 113 to rotate, the threaded ring 122 will drive the fixed shell 121 to slide up and down along the outer wall of the sliding column 114.

[0024] The limiting component 21 includes a nut 211 fixedly connected to the side wall of the housing 14. A groove 212 is provided on the side wall of the nut 211, and a lead rod 213 is threadedly connected to the inner wall of the groove 212. To address the issue of hinge deformation after prolonged use, especially with heavy wooden doors used outdoors, the equipment incorporates a pressure mechanism 2 and a pushing mechanism 3. When the door frame deforms due to prolonged hinge use, workers can adjust its position by turning the three lead screws 213. Figure 3As shown, when the lead screw 213 is turned at position H, the sliding shell 15 is forced to slide slowly along the inner wall of the outer shell 14, adjusting the left and right position of the rotating column 111. When the lead screw 213 is turned at position L, the sliding block 16 is forced to slide along the inner wall of the sliding shell 15, adjusting the front and back position of the rotating column 111. When the hexagonal screw 112 is turned, the height of the fixed shell 121, the fixed plate 123, and the wooden door is adjusted. Through the application of the above components, the hinge mechanism can adapt to changes in the wooden door, improving the service life of the hinge mechanism.

[0025] The auxiliary component 22 includes three sliding grooves 221 opened on the side wall of the lead screw 213, and a fixing block 222 is slidably connected to the inner wall of the three sliding grooves 221. An annular groove 223 is opened on the side wall of the nut 211. Some wooden doors are too heavy and require a support wheel to be installed at the edge of the door. When the support wheel passes over the road, if the road surface is uneven, it will cause the support wheel to vibrate. This vibration will be transmitted through the wooden door to the hinge structure, causing the two lead rods 213 and the threaded rod 113 to be subjected to high-frequency vibration. The decrease of high-frequency vibration causes the lead rods 213 and the threaded rod 113 to rotate, causing the connection between the hinge structure and the wooden door to deviate. To address the issue of misalignment between the hinge structure and the wooden door, a pressure mechanism 2 and a pushing mechanism 3 are installed inside the equipment, such as... Figure 11 As shown, under normal conditions, spring 313 is in a contracted state, which will cause the annular plate 312, sliding plate 311 and fixing ring 321 to move closer to the outer shell 14. At the same time, the mounting ring 322 will cause several spring plates 323 to contact the outer wall of the fixing block 222. The contacting spring plates 323 will be resisted and tilted outward, presenting a state P. The spring plates 323 on both sides of the P position will restrict the rotation of the fixing block 222, and the fixing block 222 will restrict the rotation of the screw 213. Similarly, the bottom component of the threaded ring 122 also restricts the rotation of the threaded rod 113. Through the application of the above components, the phenomenon of the hinge structure loosening of the internal threaded components due to high frequency vibration during opening and closing, causing the wooden door to deviate in position, is effectively prevented.

[0026] The pressure application assembly 31 includes a sliding plate 311 slidably connected to the inner wall of the slide groove 212, an annular plate 312 fixedly connected to the side wall of the sliding plate 311, and a spring 313 fixedly connected to the side wall of the annular plate 312. Utilizing the characteristic of the spring sheet 323 restricting the fixing block 222, after tilting upwards at position P, the distance between the spring sheets 323 on both sides of the fixing block 222 will be wider than the width of the fixing block 222. This allows a small gap to be left on both sides of the fixing block 222, such as... Figure 11At position O, when the hinge structure is subjected to high-frequency vibration, the high-frequency vibration will force the fixing block 222 to reciprocate and rotate a short distance between the two spring plates 323. Through the application of the above components, it is ensured that even if the hinge structure rusts due to water accumulation or other reasons in outdoor environment, the screw rod 213 and nut 211 will be in a short-distance movement state for a long time, which will greatly reduce the state of rusting at the connection position of the screw rod 213 and nut 211.

[0027] The limiting component 32 includes a fixing ring 321 fixedly connected to the side wall of the sliding plate 311, an mounting ring 322 fixedly connected to the side wall of the fixing ring 321, a plurality of spring plates 323 fixedly connected to the inner wall of the mounting ring 322, and a pulling column 324 fixedly connected to the side wall of the sliding plate 311. When the position of the lead screw 213 and the de-threading rod 113 needs to be adjusted, the pulling column 324 can be pulled first to make the spring plate 323 move away from the fixed block 222. Then, the operator can twist the threaded rod 113 or the lead screw 213 to complete the position adjustment. During the adjustment of the lead screw 213, the lead screw 213 will drive the three fixed blocks 222 to slide along the inner wall of the annular groove 223. After the adjustment is completed, it will stop at any position. Then, the staff will release the pulling column 324, so that the spring 313 drives the annular plate 312 to reset. Finally, the spring plate 323 will contact the outer wall of the fixed block 222, causing some of the spring plates 323 to tilt outward. The width of the spring plate 323 is smaller than the width of the fixed block 222. Through the design of the above components, the fixed block 222 can only drive a single spring plate 323 to tilt outward. If a single fixed block 222 compresses two spring plates 323 to tilt outward, under the external high-frequency vibration, the lead screw 213 itself will rotate slightly. Finally, the fixed block 222 will be stuck at the bottom of the single spring plate 323, completing the limiting function.

[0028] One specific application of this embodiment is as follows: Before use, the bottom base 13 is fixed to the ground, and then the top base 13 is fixed to the wall. At this time, the fixing plate 123 is fixed to the wooden door. When the wooden door is opened and closed, the wooden door will rotate around the fixing shell 121.

[0029] To address the issue of hinge deformation after prolonged use, especially in outdoor applications where wooden doors are heavy, the equipment incorporates a pressure mechanism 2 and a pushing mechanism 3. When the door frame deforms due to prolonged hinge use, workers can adjust its position by turning three lead screws 213. Figure 3As shown, when the screw 213 is turned at position H, the sliding shell 15 will be forced to slide slowly along the inner wall of the outer shell 14, adjusting the left and right position of the rotating column 111. When the screw is turned at position L, the sliding block 16 will be forced to slide along the inner wall of the sliding shell 15, adjusting the front and back position of the rotating column 111. When the hexagonal screw 112 is turned, the height of the fixed shell 121, the fixed plate 123, and the wooden door will be adjusted. Through the application of the above components, the hinge mechanism can adapt to the changes of the wooden door, improving the service life of the hinge mechanism. Some wooden doors are too heavy and require a support wheel to be installed at the edge of the door. When the support wheel passes over the road, if the road surface is uneven, it will cause the support wheel to vibrate. This vibration will be transmitted through the wooden door to the hinge structure, causing the two lead rods 213 and the threaded rod 113 to be subjected to high-frequency vibration. The decrease of high-frequency vibration causes the lead rods 213 and the threaded rod 113 to rotate, causing the connection between the hinge structure and the wooden door to deviate. To address the issue of misalignment between the hinge structure and the wooden door, a pressure mechanism 2 and a pushing mechanism 3 are installed inside the equipment, such as... Figure 11 As shown, under normal conditions, spring 313 is in a contracted state, which will drive the annular plate 312, sliding plate 311 and fixing ring 321 to move closer to the outer shell 14. At the same time, the mounting ring 322 will drive several spring plates 323 to contact the outer wall of the fixing block 222. The contacting spring plates 323 will be resisted and tilted outward, presenting a state P. The spring plates 323 on both sides of the P position will restrict the rotation of the fixing block 222, and the fixing block 222 will restrict the rotation of the screw 213. Similarly, the bottom component of the threaded ring 122 also restricts the rotation of the threaded rod 113. Through the application of the above components, the phenomenon of the hinge structure loosening of the internal threaded components due to high frequency vibration during opening and closing, causing the wooden door to deviate in position, is effectively prevented. When the position of the lead screw 213 and the de-threading rod 113 needs to be adjusted, the pulling column 324 can be pulled first to make the spring plate 323 move away from the fixed block 222. Then, the operator can twist the threaded rod 113 or the lead screw 213 to complete the position adjustment. During the adjustment of the lead screw 213, the lead screw 213 will drive the three fixed blocks 222 to slide along the inner wall of the annular groove 223. After the adjustment is completed, it will stop at any position. Then, the staff will release the pull column 324, so that the spring 313 drives the annular plate 312 to reset. Finally, the spring plate 323 will contact the outer wall of the fixed block 222, causing some of the spring plates 323 to tilt outward. The width of the spring plate 323 is smaller than the width of the fixed block 222. Through the design of the above components, the fixed block 222 can only drive a single spring plate 323 to tilt outward. If a single fixed block 222 compresses two spring plates 323 to tilt outward, under the external high-frequency vibration, the lead screw 213 itself will rotate slightly. Finally, the fixed block 222 will be stuck at the bottom of the single spring plate 323, completing the limiting function. Utilizing the characteristic of the spring sheet 323 restricting the fixing block 222, after tilting upwards at position P, the distance between the spring sheets 323 on both sides of the fixing block 222 will be wider than the width of the fixing block 222. This allows a small gap to be left on both sides of the fixing block 222, such as... Figure 11 At position O, when the hinge structure is subjected to high-frequency vibration, the high-frequency vibration will force the fixing block 222 to reciprocate and rotate a short distance between the two spring plates 323. Through the application of the above components, it is ensured that even if the hinge structure rusts due to water accumulation or other reasons in outdoor environment, the screw rod 213 and nut 211 will be in a short-distance movement state for a long time, which will greatly reduce the state of rusting at the connection position of the screw rod 213 and nut 211.
