Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hinges, in particular to a novel hydraulic device used for door hinges. Background Art

[0002] A hinge is a device used to connect two objects, usually made of metal or plastic. When used for a door leaf, it often has two leaves and a shaft. The two leaves are respectively connected to the door leaf and the door frame. The shaft sleeves of the two leaves are sleeved on the shaft to form a rotatable connection. There are many existing technologies for hinges:

[0003] For example, a spring hydraulic hinge with a Chinese patent publication number of CN211313799U relates to the hinge technology field, including: a spring hinge and a hydraulic hinge coaxially arranged with the hydraulic hinge, the spring hinge including a first blade, a second blade and an elastic device rotatably connecting the first blade and the second blade, and the hydraulic hinge including a third blade, a fourth blade and a hydraulic booster device rotatably connecting the third blade and the fourth blade. The combination of the spring hinge and the hydraulic hinge can mitigate the impact when the door leaf rebounds to the door frame, thereby reducing the impact sound and the damage to the door leaf and the door frame caused by the impact, and has a high practical value;

[0004] The current door hinge hydraulic device will set a spring part at the end of the hydraulic pump. Through the combination of the spring and the hydraulic pump, the impact caused by the door leaf rebounding to the door frame can be reduced. However, the spring is a consumable part. Repeated use will easily cause the spring to lose its lubrication, resulting in reduced spring elasticity, which in turn affects the overall use effect of the door hinge. In view of this, we propose a new hydraulic device for door hinges. Utility Model Content

At the same time, the cotton absorption pad laid on the side of the push plate close to the spring part can absorb excess lubricating oil and reduce the leakage of lubricating oil.

[0007] Therefore, the utility model provides a new type of hydraulic device for door hinges, which includes a hydraulic hinge body, the hydraulic hinge body includes a hydraulic pump, the end of the hydraulic pump is connected to a middle rod, the other end of the middle rod is connected to a base, the surface of the middle rod is sleeved with a spring member, the end of the spring member close to the base is connected to a push plate, the push plate is sleeved on the surface of the middle rod, the end of the spring member close to the hydraulic pump is in contact with a lubrication component, and the end of the lubrication component is connected to a conveying component for lubricating the surface of the spring member.

[0025] The current door hinge hydraulic device will have a spring part installed at the end of the hydraulic pump. Through the combination of the spring and the hydraulic pump, the impact caused by the door leaf rebounding to the door frame can be reduced. However, the spring is a consumable part. Repeated use can easily cause the spring to lose its lubrication, reduce the spring elasticity, and then affect the overall use effect of the door hinge.

[0026] See also Figure 1-Figure 4 As shown, the device includes a hydraulic hinge body 1, which includes a hydraulic pump 11. The end of the hydraulic pump 11 is connected to a middle rod 15, and the other end of the middle rod 15 is connected to a base 13. The surface of the middle rod 15 is sleeved with a spring member 12. The end of the spring member 12 close to the base 13 is connected to a push plate 14, and the push plate 14 is sleeved on the surface of the middle rod 15. The end of the spring member 12 close to the hydraulic pump 11 is in contact with a lubrication component 2, and the end of the lubrication component 2 is connected to a conveying component 3 for lubricating the surface of the spring member 12.

[0027] First, the specific structure of the lubrication assembly 2 is disclosed. The lubrication assembly 2 includes an oil storage bag 21 sleeved on the end of the middle rod 15. The surface of the oil storage bag 21 is made of soft material. A plurality of extrusion holes 22 are opened at one end of the oil storage bag 21 close to the spring member 12. By using the oil storage bag 21 arranged at the end of the spring member 12 and the surface of the oil storage bag 21 being made of soft material, when the spring member 12 is compressed under pressure, the oil storage bag 21 can be squeezed, so that the lubricating oil inside it can flow to the surface of the spring member 12 through the extrusion holes 22, thereby achieving the effect of lubricating the spring member 12.

[0028] Secondly, the specific structure of the conveying assembly 3 is disclosed. The conveying assembly 3 includes two conveying holes 31 opened on the side of the oil storage bag 21 close to the spring member 12. Auxiliary vertical rods 32 are installed inside the two conveying holes 31. The interior of the two auxiliary vertical rods 32 is a hollow structure. The other ends of the two auxiliary vertical rods 32 are in contact with the inner wall of the spring member 12. The other ends of the two auxiliary vertical rods 32 are opened with leakage holes 33. When the spring member 12 squeezes the oil storage bag 21, the lubricating oil inside the oil storage bag 21 can flow to the inside of the auxiliary vertical rods 32 through the conveying holes 31, and lubricate the inner wall of the spring member 12 through the leakage holes 33, which effectively improves the lubrication effect on the spring member 12. Among them, the inner wall of the conveying hole 31 is provided with an elastic pad. When the oil storage bag 21 is squeezed, the elastic pad is deformed and opened by force. When the oil storage bag 21 is not under force, the conveying hole 31 is in a closed state, which reduces oil leakage.

[0029] The improvement of this embodiment lies in that: first, the base 13 is used to push and squeeze the spring member 12, so that the hydraulic hinge body 1 can operate normally. The oil storage bag 21 is arranged at the end of the spring member 12, and the surface of the oil storage bag 21 is made of soft material. When the spring member 12 is compressed by pressure, the oil storage bag 21 can be squeezed, so that the lubricating oil inside it can flow to the surface of the spring member 12 through the squeezing hole 22, so as to achieve the effect of lubricating the spring member 12. When the spring member 12 squeezes the oil storage bag 21, the lubricating oil inside the oil storage bag 21 can flow to the inside of the auxiliary vertical rod 32 through the conveying hole 31, and lubricate the inner wall of the spring member 12 through the leakage hole 33, thereby effectively improving the lubrication effect of the spring member 12.

[0030] Considering the sliding of the lubricating oil on the surface of the spring member 12, in order to reduce the leakage of the lubricating oil from the other end of the spring member 12, Figure 1-Figure 2 As shown, a cotton suction pad 4 is laid on one side surface of the push plate 14 close to the spring member 12 .

[0031] The improvement lies in: using a cotton suction pad 4 laid on the side of the push plate 14 close to the spring part 12, the other end of the spring part 12 can be attached to the surface of the cotton suction pad 4. When the lubricating oil slides to the other end of the spring part 12, it can be absorbed by the cotton suction pad 4 to reduce the leakage of the lubricating oil.

[0032] When the door hinge is started, the spring member 12 will be squeezed toward the hydraulic pump 11, so that the lubricating oil in the oil storage bag 21 can be squeezed out from the inside of the squeezing hole 22. Therefore, in order to reduce the oil discharge of the oil storage bag 21 when the spring member 12 is not squeezed, Figure 3-Figure 4As shown, a leak-proof member 5 is installed inside the extrusion hole 22 , and the leak-proof member 5 is composed of four blades 51 . The centers of the four blades 51 are connected to connecting pipes 53 , and the other ends of the connecting pipes 53 are connected to the middle circular plate 52 .

[0033] The improvement lies in that: by utilizing four blades 51 arranged on the inner wall of the extrusion hole 22, the middle circular plate 52 can be installed in the middle of the blade 51 through the connecting pipe 53. When the oil storage bag 21 is not squeezed, the middle circular plate 52 can be placed at the center of the four blades 51 to block the extrusion hole 22. When the oil storage bag 21 is squeezed by the spring part 12, the leak-proof part 5 made of elastic material is deformed by pressure, so that there is a gap between the four blades 51 and the middle circular plate 52, which facilitates the leakage of lubricating oil.

[0034] In summary, the working principle of the present scheme is as follows: first, the base 13 is used to push and squeeze the spring member 12, so that the hydraulic hinge body 1 can operate normally. The oil storage bag 21 is arranged at the end of the spring member 12, and the surface of the oil storage bag 21 is made of soft material. When the spring member 12 is compressed by pressure, the oil storage bag 21 can be squeezed so that the lubricating oil inside it can flow to the surface of the spring member 12 through the extrusion hole 22, so as to achieve the effect of lubricating the spring member 12. The four blades 51 arranged on the inner wall of the extrusion hole 22 are used, so that the middle circular plate 52 can be installed in the middle of the blade 51 through the connecting pipe 53. When the oil storage bag 21 is not squeezed, the middle circular plate 52 can be placed at the center of the four blades 51 to block the extrusion hole 22. When the oil storage bag 21 is squeezed by the spring member 12, the leak-proof member 5 made of elastic material is deformed by pressure, so that there is a gap between the four blades 51 and the middle circular plate 52, which is convenient for the lubricating oil to leak out.

[0035] When the spring member 12 squeezes the oil storage bag 21, the lubricating oil inside the oil storage bag 21 can flow to the inside of the auxiliary upright 32 through the delivery hole 31, and lubricate the inner wall of the spring member 12 through the leakage hole 33, thereby effectively improving the lubrication effect of the spring member 12. By utilizing the cotton suction pad 4 laid on the side of the push plate 14 close to the spring member 12, the other end of the spring member 12 can be attached to the surface of the cotton suction pad 4. When the lubricating oil slides to the other end of the spring member 12, it can be absorbed by the cotton suction pad 4 to reduce the leakage of the lubricating oil.
