Description

Technical Field

[0001] The invention relates to the technical field of hinge structures, and in particular to a box-type hinge structure capable of providing active maintenance. Background Art

[0002] In a Chinese patent with patent publication number CN1749517A, a damping adjustable rust-proof hinge and a method thereof are disclosed, which include a fixed plate, a movable plate and an assembly shaft. The fixed plate is concave in the middle and has polygonal limit assembly holes on the convex assembly feet on both sides. The movable plate is concave on both sides and has open circular assembly holes on the convex assembly feet in the middle. One of the two open sides of the circular assembly hole is fixedly connected to the movable plate body, and a reinforced adjustment plate is extended on the other side. The assembly shaft is composed of a cylindrical shaft arranged in the middle and a polygonal cylindrical shaft arranged at both ends. The basic components are made of plastic with high toughness, high wear resistance and high strength, which effectively solves the problems of rust and short working life during use. The damping size can be manually adjusted and controlled as needed during use, which increases the safety of use and work reliability.

[0003] However, the following defects still exist in the specific use of the comparative documents:

[0004] 1. In the hinge design of the comparative document, a plastic material with high toughness, high wear resistance and high strength is used as its basic structure. This choice undoubtedly effectively solves the rust problem that is easy to occur in traditional metal hinges and significantly extends the service life of the hinge. However, since the basic structure of the hinge is made of plastic, and the friction coefficient between plastics is higher than that of metal, this means that during the rotation of the hinge, a relatively large friction force will be generated. Due to the increase in friction, the hinge will generate more heat during operation. However, the comparative document does not clearly mention whether the plastic material has good high temperature resistance. If the container needs to quickly load and unload large and heavy goods, such as machinery and equipment, large engineering accessories, etc., the hinge part will be frequently opened and closed to achieve rapid access to the contents of the container. Therefore, the hinge will generate heat inside when it continues to work at high load. If the heat resistance of the plastic material is insufficient, deformation or performance degradation may occur, which will affect the overall use effect and stability of the hinge.

[0005] 2. In comparison, although high-strength plastics have improved in strength and wear resistance, their performance under extreme loads is still inferior to that of metals. Since the molecular structure of metals is tighter, they can more effectively disperse and resist external pressure, thereby maintaining the integrity and stability of the structure. At the same time, when metal hinges are subjected to external forces, they can resist greater deformation due to their higher elastic modulus and yield strength. When plastic hinges are subjected to the same force, their surface lubrication effect is poorer than that of metals under high loads.

[0006] Therefore, a box-type hinge structure that can provide active maintenance is proposed to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a box-type hinge structure that can provide active maintenance to solve the problems in the prior art that plastic hinges have poor adaptability and the lubrication effect between hinges is lower than that of metal materials.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solutions: a box-type hinge structure capable of providing active maintenance, comprising a first hinge plate, a rotating shaft being rotatably connected in the first hinge plate, a second hinge plate being fixedly connected to the outer surface of the rotating shaft, and an auxiliary lubrication mechanism and an automatic pressurized circulatory lubrication mechanism, wherein the auxiliary lubrication mechanism is arranged in the middle of the second hinge plate and the first hinge plate, and the automatic pressurized circulatory lubrication mechanism is arranged at the upper end of the first hinge plate;

[0009] The auxiliary lubrication mechanism is used for rotational lubrication between the rotating shaft and the first hinge plate;

[0010] The automatic pressurized circulating lubrication mechanism is used for circulating the lubricating fluid on the surface of the rotating shaft.

[0011] As an improvement, the auxiliary lubrication mechanism includes an annular choke groove body, which is sleeved on the outer surface of the rotating shaft, and the bottom of the annular choke groove body is fixedly connected to the connection between the second hinge plate and the first hinge plate, and the middle part of the upper surface of the annular choke groove body is concave and has a groove.

[0012] As an improvement, the auxiliary lubrication mechanism also includes an annular slot body, the outer surface of the annular slot body is set to a cone, the size of the cone setting of the outer surface of the annular slot body is adapted to the groove of the annular choke slot body, the annular slot body is rotatably connected in the groove of the annular choke slot body, an oil filling groove is provided on the inner wall of the connection between the first hinge plate and the second hinge plate and the rotating shaft, an oil storage hopper is provided at the bottom of the first hinge plate, the oil filling groove is fixedly connected to the oil storage hopper near the bottom of the first hinge plate, and a guide groove is provided in the first hinge plate.

[0013] As an improvement, the end of the oil storage hopper away from the oil filling groove is fixedly connected to the guide groove, the end of the guide groove away from the oil storage hopper is fixedly connected to a one-way valve choke valve, the end of the one-way valve choke valve away from the guide groove is fixedly connected to a protective bin, and the bottom of the protective bin is fixedly connected to the upper surface of the first hinged plate.

[0014] As an improvement, the automatic pressurized circulating lubrication mechanism includes a protective bin, a booster plate is slidably connected to the inner wall of the protective bin, a transmission shaft is rotatably connected to the middle of the protective bin, the middle of the booster plate is slidably connected to the outer surface of the transmission shaft, and an extrusion groove is provided on the outer surface of the transmission shaft.

[0015] As an improvement, an extrusion column is slidably connected in the extrusion groove, and the end of the extrusion column away from the extrusion groove is fixedly connected to the boost plate, the bottom end of the transmission shaft is fixedly connected to a turntable, the turntable has a lubrication groove on the side away from the transmission shaft, and a lubrication ball is slidably connected in the lubrication groove of the turntable.

[0016] As an improvement, the upper surface of the first hinged plate is fixedly connected with an oblique guide plate, the bottom of the lubricating ball abuts against the oblique guide plate, the bottom of the oblique guide plate is fixedly connected to the upper surface of the first hinged plate, and the upper end of the rotating shaft is fixedly connected to the middle of the bottom end of the rotating plate.

[0017] Compared with the prior art, the box-type hinge structure that can provide active maintenance provided by the present invention has the following beneficial effects:

[0018] 1. Through the opening of the guide groove, when the second hinge plate drives the rotating shaft to rotate in the first hinge plate, the rotation of the rotating shaft will cause the lubricating oil in the guide groove to flow through the guide groove and the lubricating oil to be coated on the surface of the rotating shaft. The rotation of the rotating shaft will evenly coat the lubricating oil on the surface of the rotating shaft to form a lubricating film, which not only effectively reduces the friction and wear of the hinge during the rotation process, but also improves the operation efficiency of the hinge and prolongs its service life;

[0019] Compared with the hinges made of plastic in the comparative documents, the provision of the annular flow-blocking groove body and the annular slot body can ensure that the lubricating oil is circulated inside the hinge when the second hinge plate and the first hinge plate rotate in the rotating shaft, which not only reduces the possibility of lubricating oil leakage, but also keeps the equipment and its surrounding environment clean, reduces the risk of failure caused by frictional overheating or excessive wear of components, thereby improving the safety and reliability of the equipment.

[0020] 2. Through the setting of the automatic pressurized circulating lubrication mechanism, the rotation of the rotating shaft drives the turntable to drive the transmission shaft to rotate, and the rotation of the transmission shaft drives the booster plate to slide back and forth on the inner wall of the protective bin. Through the setting of the protective bin and the booster plate, the present invention cleverly drives the movement of the axis through its unique rotation mechanism, and then drives the booster plate to slide back and forth in the protective bin. This action not only creates a dynamic compression zone, but also greatly optimizes the recycling efficiency of the lubricating oil.

[0021] Compared with the metal materials mentioned in the comparative documents that are susceptible to corrosion and wear under special circumstances, the arrangement of the present invention ensures that the lubricating oil can be continuously and evenly distributed in various key friction parts of the hinge shaft when the hinge rotates, which not only effectively reduces the heat and wear generated by friction, but also extends the service life of the hinge. Secondly, through the reciprocating sliding of the push plate, the lubricating oil can be extracted from the guide groove into the protective bin through the action of the booster plate for continuous recycling in the protective bin, reducing the waste of lubricating oil, while achieving the effect of active maintenance and reducing the maintenance cost caused by changing the lubricating oil.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0034] Example

[0035] Please refer to Figures 1 to 7 As shown:

[0036] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a box-type hinge structure that can provide active maintenance, including a first hinge plate 1, a rotating shaft 12 is rotatably connected in the first hinge plate 1, and a second hinge plate 11 is fixedly connected to the outer surface of the rotating shaft 12, and also includes an auxiliary lubrication mechanism 2 and an automatic pressurized circulatory lubrication mechanism 3, the auxiliary lubrication mechanism 2 is arranged in the middle of the second hinge plate 11 and the first hinge plate 1, and the automatic pressurized circulatory lubrication mechanism 3 is arranged at the upper end of the first hinge plate 1;

[0037] The auxiliary lubrication mechanism 2 is used for rotational lubrication between the rotating shaft 12 and the first hinge plate 1;

[0038] The automatic pressurized circulating lubrication mechanism 3 is used for circulating the lubricating fluid on the surface of the rotating shaft 12;

[0039] The auxiliary lubrication mechanism 2 includes an annular choke groove body 21, which is sleeved on the outer surface of the rotating shaft 12. The bottom of the annular choke groove body is fixedly connected to the connection between the second hinge plate and the first hinge plate. The middle part of the upper surface of the annular choke groove body is concave and has a groove.

[0040] The auxiliary lubrication mechanism 2 also includes an annular slot body 22, which is rotatably connected to the groove of the annular flow blocking slot body 21. An oil filling groove 23 is provided on the inner wall of the connection between the first hinge plate 1 and the second hinge plate 11 and the rotating shaft 12. An oil storage hopper 24 is provided at the bottom of the first hinge plate 1. The oil filling groove 23 is fixedly connected to the oil storage hopper 24 near the bottom of the first hinge plate 1.

[0041] The end of the oil storage hopper 24 away from the oil filling groove 23 is fixedly connected to the guide groove 25, and the end of the guide groove 25 away from the oil storage hopper 24 is fixedly connected to a one-way valve choke valve 26, and the one-way valve choke valve 26 away from the guide groove 25 is fixedly connected to a protection bin 31, and the bottom of the protection bin 31 is fixedly connected to the upper surface of the first hinged plate 1;

[0042] The middle part of the upper surface of the annular flow-blocking slot body 21 is concave and has a groove, the outer surface of the annular slot body 22 is set to be conical, and the size of the conical setting of the outer surface of the annular slot body 22 is adapted to the groove of the annular flow-blocking slot body 21.

[0043] The reference document does not explicitly mention whether the plastic material has good high temperature resistance. Therefore, when the hinge is working continuously and generating heat, if the heat resistance of the plastic material is insufficient, the surface lubrication effect of the plastic hinge under high load is poorer than that of metal. Through the implementation of this embodiment, the guide groove 25 is opened. When the second hinge plate 11 drives the shaft 12 to rotate in the first hinge plate 1, the rotation of the shaft 12 can make the lubricating oil in the guide groove 25 flow through the guide groove 25 and can coat the lubricating oil on the surface of the shaft 12. The rotation of the shaft 12 can evenly coat the surface of the shaft 12 with the lubricating oil on the surface of the shaft 12 to form a lubricating film, which not only effectively reduces the friction and wear of the hinge during rotation, but also improves the operation efficiency of the hinge and prolongs its service life.

[0044] For further examples, please refer to Figures 1 to 7 As shown:

[0045] The automatic pressurized circulating lubrication mechanism 3 includes a protective chamber 31, a booster plate 32 is slidably connected to the inner wall of the protective chamber 31, a transmission shaft 33 is rotatably connected to the middle of the protective chamber 31, the middle of the booster plate 32 is slidably connected to the outer surface of the transmission shaft 33, and an extrusion groove 35 is opened on the outer surface of the transmission shaft 33;

[0046] An extrusion column is slidably connected in the extrusion groove 35, and the end of the extrusion column away from the extrusion groove 35 is fixedly connected to the supercharging plate 32, and a turntable 34 is fixedly connected to the bottom end of the transmission shaft 33. A lubrication groove is provided on the turntable 34 away from the transmission shaft 33, and a lubrication ball 36 is slidably connected in the lubrication groove of the turntable 34;

[0047] The upper surface of the first hinge plate 1 is fixedly connected with an oblique guide plate 37, the bottom of the lubricating ball 36 abuts against the oblique guide plate 37, the bottom of the oblique guide plate 37 is fixedly connected to the upper surface of the first hinge plate 1, and the upper end of the rotating shaft 12 is fixedly connected to the middle of the bottom end of the rotating plate 34;

[0048] Among them: an extrusion column is slidably connected in the extrusion groove 35, and the end of the extrusion column away from the extrusion groove 35 is fixedly connected to the supercharging plate 32, and a one-way valve is installed in the oblique guide plate 37, that is, the flow direction of the lubricating oil in the one-way valve can only flow from the protection bin 31 to the oblique guide plate 37, but cannot flow from the oblique guide plate 37 to the protection bin 31.

[0049] Although high-strength plastics have been improved in strength and wear resistance, their performance under extreme loads is still inferior to that of metals. Since the molecular structure of metals is tighter, they can more effectively disperse and resist external pressure, thereby maintaining the integrity and stability of the structure. At the same time, when metal hinges are subjected to external forces, they can resist greater deformation due to their higher elastic modulus and yield strength, while plastic hinges may be more likely to deform when subjected to the same magnitude of force, affecting the use effect and safety. Through the implementation of this embodiment, through the automatic pressurized circulating lubrication mechanism 3, the rotating shaft 12 drives the turntable 34 to drive the transmission shaft 33 to rotate, and the rotation of the transmission shaft 33 drives the booster plate 32 to reciprocate on the inner wall of the protective bin 31. Through the setting of the protective bin 31 and the booster plate 32, the present invention cleverly drives the movement of the axis through its unique rotation mechanism, thereby driving the booster plate 32 to achieve reciprocating sliding in the protective bin 31. This action not only creates a dynamic compression zone, but also greatly optimizes the recycling efficiency of the lubricating oil.

[0050] Everything in the above example works like this:

[0051] In the initial state: the oil storage hopper 24 and the guide groove 25 are both filled with lubricating oil.

[0052] The following is a working process of the auxiliary lubrication mechanism 2 for rotational lubrication between the rotating shaft 12 and the first hinge plate 1 and the automatic pressurized circulating lubrication mechanism 3 for circulating the lubricating fluid on the surface of the rotating shaft 12:

[0053] When in use, the user first fixes the positioning holes on the first hinge plate 1 and the second hinge plate 11 of the hinge to the box body and the box door. At this time, because the oil storage hopper 24 and the guide groove 25 are filled with lubricating liquid, when the operator fixes the second hinge plate 11 on the box door, when the box door is turned, the second hinge plate 11 will drive the fixedly connected rotating shaft 12 to rotate in the first hinge plate 1, such as Figure 1 As shown, at this time, since the rotating shaft 12 is fixedly connected to the bottom of the rotating disk 34, Figure 7As shown, a lubrication groove is provided on one side of the turntable 34 away from the transmission shaft 33, a lubrication ball 36 is slidably connected in the lubrication groove of the turntable 34, and the end of the lubrication ball 36 away from the turntable 34 is slidably connected to the oblique guide plate 37, so the rotation of the shaft 12 will drive the turntable 34 to start driving the lubrication ball 36 to rotate on the oblique guide plate 37. At this time, because the protection bin 31 and the oblique guide plate 37 are connected to each other, an extrusion groove 35 is provided on the outer surface of the transmission shaft 33, and an extrusion column is slidably connected in the extrusion groove 35, and the end of the extrusion column away from the extrusion groove 35 is fixedly connected to the supercharging plate 32. At the same time, when the turntable 34 rotates, the protective bin 31 and the oblique guide plate 37 are connected to each other. When the disc 34 rotates, the mutual squeezing effect of the squeezing column and the squeezing groove 35 will drive the booster plate 32 to slide back and forth on the inner wall of the protective chamber 31. At this time, due to the opening and closing of the first hinge plate 1 in the second hinge plate 11, the second hinge plate 11 is driven to rotate in different directions in the first hinge plate 1, which will drive the booster plate 32 to slide back and forth in the squeezing groove 35. At this time, because the one-way valve choke valve 26 is connected to the protective chamber 31, and the connecting port is located below the booster plate 32, since the booster plate 32 and the protective chamber 31 are well sealed, the booster plate 32 slides back and forth in the protective chamber 31. A dynamic compression zone will be formed in the protection chamber 31. Since the flow direction of the one-way valve choke 26 is set to flow into the protection chamber 31 only from one side of the one-way valve choke 26, but not from the protection chamber 31 to the one-way valve choke 26. At the same time, the one-way valve installed in the oblique guide plate 37 can only flow from the protection chamber 31 to the oblique guide plate 37, but not from the oblique guide plate 37 to the protection chamber 31. Therefore, when the bottom of the protection chamber 31 slides upward, a negative pressure zone will be formed at the bottom of the boost plate 32. At this time, the lubricating oil in the one-way valve choke 26 will be sucked in by the air pressure. Attached to the protective bin 31, when the protective bin 31 slides downward, the lubricating oil in the oil storage hopper 24 will be pushed into the oblique guide plate 37 by the action of air pressure, and the rotating shaft 12 will drive the turntable 34 to drive the transmission shaft 33 to rotate, and the rotation of the transmission shaft 33 will drive the booster plate 32 to slide back and forth on the inner wall of the protective bin 31. Through the arrangement of the protective bin 31 and the booster plate 32, the present invention can achieve reciprocating sliding in the protective bin 31 through its unique rotation mechanism. This action not only creates a dynamic compression zone, but also greatly optimizes the recycling efficiency of the lubricating oil.

[0054] Compared with the hinges made of plastic material mentioned in the comparative document, when the hinges made of plastic material are working under continuous high load, heat is generated inside the hinges. If the heat resistance of the plastic material is insufficient, deformation or performance degradation may occur, thereby affecting the overall use effect and stability of the hinge; and through the setting of the present invention, when the hinge is rotating, it ensures that the lubricating oil can be continuously and evenly distributed in the key friction parts of the hinge shaft 12, which not only effectively reduces the heat and wear generated by friction, but also extends the service life of the hinge. Secondly, through the reciprocating sliding of the booster plate 32, the lubricating oil can be drawn from the guide groove 25 into the protective bin 31 through the action of the booster plate 32 for continuous circulation in the protective bin 31, thereby reducing the dripping of lubricating oil and causing insufficient lubrication between the hinges, so that the metal parts inside the hinge are in direct contact and rub against each other, thereby reducing the wear between metals caused by poor lubrication.

[0055] Since the oblique guide plate 37 is interconnected with the oil filling groove 23, and since the inner walls of the connection between the first hinge plate 1 and the second hinge plate 11 and the rotating shaft 12 are provided with the oil filling groove 23, when the booster plate 32 pushes the lubricating oil at the bottom of the protective bin 31 into the oil filling groove 23, as the rotating shaft 12 rotates, the lubricating oil in the oil filling groove 23 will be evenly coated on the surface of the rotating shaft 12. At this time, the ingenious setting of the guide groove 25 in the present invention becomes the key to the circulation of the lubricating oil. When the second hinge plate 11 drives the rotating shaft 12 to rotate smoothly in the frame of the first hinge plate 1, the rotation of the rotating shaft 12 drives the air flow around it. At the same time, the lubricating oil in the oil filling groove 23 flows precisely to the surface of the rotating shaft 12 along the preset path of the guide groove 25 under the action of pressure or gravity.

[0056] As the rotating shaft 12 continues to rotate, the lubricating oil in the oil filling groove 23 is evenly coated on the entire surface of the rotating shaft 12, forming a fine lubricating film. The existence of this lubricating film greatly reduces the friction and wear generated during the relative movement of the rotating shaft 12 and the surrounding components, effectively extending the service life of the hinge. At the same time, due to the reduction of friction resistance, the operation of the hinge becomes smoother and more efficient, and both the opening and closing actions can be completed with lower energy consumption and faster speed; compared with the hinge made of plastic material in the comparative document, through the setting of the annular flow blocking groove body 21 and the annular slot body 22, the lubricating oil can be ensured to circulate inside the hinge when the second hinge plate 11 and the first hinge plate 1 rotate in the rotating shaft 12, which not only reduces the possibility of lubricating oil leakage, but also keeps the equipment and its surrounding environment clean, and reduces the wear caused by the frequent opening and closing of the hinge parts when quickly loading and unloading large and heavy goods, such as machinery and equipment, large engineering accessories, etc., thereby improving the safety and reliability of the equipment.
