Description

Technical Field

[0001] This utility model relates to the field of lubrication device technology, and in particular to a self-lubricating door panel flipping mechanism. Background Technology

[0002] A door panel refers to the sash-like part of a door, typically made of various materials. Different materials can be selected for door panels depending on requirements, such as solid wood doors, engineered wood doors, steel doors, and aluminum alloy doors. The door panel is one of the main components of a door, serving functions such as sound insulation, heat insulation, security, and aesthetics. Door panels can be installed in various ways, including rotating, sliding, and lifting, but rotating installation is the most common in daily life. Over time, the hinges connecting the door panel and the wall can rust, leading to difficulty opening and closing, abnormal noises, and eventually, damage to the hinges.

[0003] A search revealed a Chinese patent publication number CN204691511U, which discloses a door hinge lubrication device, including a door hinge, a door hinge sleeve fitted on the door hinge, an oil cup mounting hole on the top of the door hinge sleeve that communicates with the door hinge receiving cavity inside the door hinge sleeve, and an oil cup installed in the oil cup mounting hole.

[0004] To address the issue that the aforementioned technology is mainly used in wind turbine generator sets, requiring a large external oil reservoir for oil filling and lubrication, and is not suitable for the opening and closing of household door panels, which are relatively small and cannot accommodate large external lubrication devices, a self-lubricating door panel flipping mechanism is proposed.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-5 As shown, a self-lubricating door panel flipping mechanism includes a door panel 1. A hinge assembly is fixedly connected to one side of the door panel 1. The hinge assembly has mounting holes at both ends, and the hinge can be installed on the door and wall by screws. A crown ratchet gear set is fixedly connected above the hinge assembly. One end of the crown ratchet gear set is driven by an intermittent drive assembly. The intermittent drive assembly includes a transmission plate 12, a transmission plate 23, a transmission gear 14, and a transmission gear 25. Upper drive columns 24 are fixedly connected above the transmission plates 12 and 23, respectively. Lower drive columns 25 are fixedly connected below the transmission plates 12 and 23, respectively. One end of the lower drive column 25 on the lower side of the transmission plate 12 is driven by the crown ratchet gear set. The upper drive column 24 on the upper side of the transmission plate 12 and the lower drive column 25 on the lower side of the transmission plate 23 are driven by the transmission gear 25. One end of the upper drive column 24 on the upper side of the transmission plate 23 is driven by the transmission gear 14. One end of the transmission gear 14 is movably connected to an oil spraying assembly.

[0031] The hinge assembly includes hinge 1 2, hinge 2 3 and hinge pivot 4. One end of hinge 2 3 is fixedly connected to door panel 1, one end of hinge pivot 4 is fixedly connected to hinge 1 2, and one end of hinge 1 2 is rotatably connected to hinge 2 3.

[0032] The crown ratchet gear set includes a crown ratchet gear 10, a crown ratchet gear 21, a drive gear 17, and a lifting component. The ratchet teeth of the crown ratchet gear 10 and the crown ratchet gear 21 face opposite directions. One end of the crown ratchet gear 10 is fixedly connected to the transmission gear 14, one end of the crown ratchet gear 21 is movably connected above the crown ratchet gear 10, one end of the drive gear 17 is movably connected to the lifting component, and one end of the crown ratchet gear 21 is fixedly connected to the lifting component.

[0033] When the door panel 1 is opened by rotating, the crown ratchet gear 10 and crown ratchet gear 21 will rotate relative to each other. The rotating crown ratchet gear 21 will drive the transmission plate 12 to rotate at a certain angle. After multiple rotations, it will drive the transmission plate 12 to drive the transmission gear 25 on one side through the upper drive column 24. When the transmission gear 215 rotates, it will drive the transmission plate 23 to rotate. After the transmission plate 213 rotates multiple times, it will drive the oil spraying component to spray oil through the transmission gear 14. The oiling and lubrication operation can be performed after the door is opened and closed a certain number of times. This eliminates the need to connect a large external oil can for continuous oil supply, reduces the space occupied by the device, is suitable for small household doors, and does not require frequent maintenance.

[0034] When the crown ratchet gear 10 connected to the hinge shaft 4 reverses, it will slide relative to the crown ratchet gear 2 11. This will prevent the crown ratchet gear 2 11, transmission plate 1 12, transmission plate 2 13, transmission gear 1 14 and transmission gear 2 15 from reversing, thus preventing them from affecting the normal oil injection of the oil injection assembly.

[0035] In this embodiment, the lifting component includes a lifting rod 16 and a spring 18. One end of the lifting rod 16 and the spring 18 is fixedly connected to the crown ratchet gear 11. The upper part of the lifting rod 16 is slidably connected to the drive gear 17. One end of the spring 18 is slidably connected to one side of the drive gear 17.

[0036] When the first crown ratchet 10 connected to the hinge shaft 4 is in reverse, the second crown ratchet 11 located above can slide upwards and stop rotating itself.

[0037] In this embodiment, an oil bottle 6 is fixedly connected inside the door panel 1, and the lower end of the oil bottle 6 is fixedly connected to the oil spraying assembly. The oil bottle 6 is embedded inside the door panel 1, which does not occupy external space and reduces the problem of external pipelines.

[0038] In this embodiment, the fuel injection assembly includes a fuel outlet switch box 8, a trigger rod 19, a fuel outlet baffle 20, a fuel outlet 21, and a connection port 22. One end of the trigger rod 19 is fixedly connected to the fuel outlet baffle 20, and the other end of the trigger rod 19 is movably connected to the transmission gear 14. The fuel outlet baffle 20 is slidably connected inside the fuel outlet switch box 8. The fuel outlet 21 is opened on one side of the fuel outlet baffle 20. Connection ports 22 are opened on both sides of the fuel outlet switch box 8. One end of the lower connection port 22 is fixedly connected to a fuel injection pipe 9.

[0039] When the door panel 1 is opened and closed repeatedly, causing the transmission gear 14 to rotate, the transmission gear 14 will press the trigger rod 19 to move inward, allowing the oil outlet 21 at one end of the oil baffle 20 to connect with the connection port 22. At this time, the oil in the oil bottle 6 will flow into the hinge shaft 4 through the oil injection pipe 9 for lubrication.

[0040] In this embodiment: when the door panel 1 is rotated and opened, the first crown ratchet 10 and the second crown ratchet 11 will rotate relative to each other. The rotating second crown ratchet 11 will drive the first transmission plate 12 to rotate at a certain angle. After multiple rotations, it will drive the first transmission plate 12 to drive the second transmission gear 15 on one side through the upper drive column 24. When the second transmission gear 15 rotates, it will drive the second transmission plate 13 to rotate. After the second transmission plate 13 rotates multiple times, it will drive the oil injection assembly to spray oil through the first transmission gear 14.

[0041] The transmission gear 14 will press the trigger rod 19 to move inward, allowing the oil outlet 21 at one end of the oil baffle 20 to connect with the connection port 22. At this time, the oil in the oil bottle 6 will flow into the hinge shaft 4 through the oil injection pipe 9 for lubrication. The oil injection and lubrication operation can be performed after the door is opened and closed a certain number of times. This eliminates the need to connect a large external oil can for continuous oil supply, reduces the space occupied by the device, is suitable for small household doors, and does not require frequent maintenance.

[0042] When the crown ratchet gear 10 connected to the hinge shaft 4 reverses, it will slide relative to the crown ratchet gear 2 11. This will prevent the crown ratchet gear 2 11, transmission plate 1 12, transmission plate 2 13, transmission gear 1 14 and transmission gear 2 15 from reversing, thus preventing them from affecting the normal oil injection of the oil injection assembly.

[0043] Example 2:

[0044] A self-lubricating door panel flipping mechanism is proposed. This embodiment is based on Embodiment 1 with the following improvements, such as... Figure 1-5 As shown,

[0045] In this embodiment, a spring 23 is fixedly connected to one end of the oil outlet baffle 20 and the oil outlet switch box 8. The spring 23 can make the oil outlet 21 and the connection port 22 staggered when the oil outlet baffle 20 is not squeezed by the transmission gear 14, so as to prevent the oil from flowing out and causing waste.

[0046] In this embodiment, a baffle 5 is fixedly connected to one side of the door panel 1, and an oil filling port 7 is fixedly connected to one side of the oil bottle 6;

[0047] The oil filling port 7 facilitates the replenishment of oil to the oil bottle 6, while the baffle 5 provides a sealing effect and protects the internal components.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
