Description

Technical Field

[0001] The utility model relates to the field of hardware equipment, in particular to a rotating device with a buffering function and a top and bottom hinge and a door using the same. Background Art

[0002] A hinge is a mechanical device used to connect two solid bodies and allow rotation between them.

[0003] The existing top and bottom hinges are generally composed of a pair of mirror-symmetrical hinged joints, which can only replace traditional hinges to achieve the rotation function. Although compared with traditional hinges, they are hidden installations and can improve aesthetics, they cannot guarantee the smoothness of the door opening and closing process.

[0004] As shown in the Chinese utility model patent with the announcement number CN220687062U, it discloses a world hinge, including an upper rotating device and a lower rotating device, the lower rotating device includes a third mounting member, a fourth mounting member and a rotating ball, the fourth mounting member is detachably mounted on the third mounting member and rotatably cooperates with the third mounting member, the rotating ball is movably mounted on the fourth mounting member and cooperates with the third mounting member, the upper rotating device includes a first mounting member, a second mounting member, a rotating member and a first connecting head, one end of the rotating member is rotatably mounted on the second mounting member, and the other end is detachably mounted on the first mounting member and is limited by the first connecting head. Also disclosed is a door using it, including the above-mentioned world hinge, and also including a door leaf and a door frame, the upper and lower ends of the door leaf are rotatably mounted on the door frame through the upper rotating device and the lower rotating device respectively. The lower rotating device of the world hinge is provided with a rotating ball, which can effectively improve the smoothness of rotation, and the upper rotating device has an automatic reset function, which is easy to use.

[0005] Although the upper rotating device of the above-mentioned top and bottom hinge has an automatic reset function and can realize the function of automatic door closing, when it automatically closes the door, due to the fast rebound speed of the reset torsion spring, the door leaf hits the door frame with great force when closing, which is not only easy to cause damage but also produces loud noise, affecting the user experience. Utility Model Content

[0006] The purpose of the utility model is to provide a rotating device with a buffering function and a floor hinge and a door using the same, which can at least solve one of the above problems.

[0007] According to one aspect of the utility model, a rotating device with a buffering function is provided, comprising at least:

[0008] A first mounting member, mounted on a stationary object;

[0009] A second mounting member is mounted on the moving object;

[0010] An axle-shaped component is sleeved on the second mounting member and matched with the first mounting member;

[0011] The shaft-shaped component includes a tubular member, a first connector, a second connector and a reset torsion spring. The tubular member is sleeved in the second mounting member. The first connector and the second connector are respectively mounted at two ends of the tubular member. The reset torsion spring is mounted in the tubular member and the two ends are respectively matched with the first connector and the second connector. The second connector is connected to the second mounting member. The end of the first connector away from the reset torsion spring is limitedly matched with the first mounting member.

[0012] The first connector, the second connector, the tubular member and the second mounting member are collectively enclosed to form a receiving cavity;

[0013] A central channel for injecting a liquid object capable of slowing down the resetting of the resetting torsion spring and communicating with the accommodating cavity is opened at the center of the first connector.

[0014] Therefore, the utility model provides a rotating device with a new structure, and the working principle of the rotating device is as follows: the first mounting part is mounted on a stationary object such as a door frame, and the second mounting part is mounted on a movable object such as a door leaf. Since the top of the first connecting head is limited by the first mounting part, under the action of external force, the door leaf will drive the second mounting part and the second connecting head connected to the second mounting part to rotate together when it moves. The rotation of the second connecting head drives the reset torsion spring to deform. After the external force disappears, due to the reset function of the reset torsion spring, the second mounting part is reset, thereby realizing the automatic closing of the door leaf. The rotating device of the utility model can inject liquid objects such as resistance oil or damping grease into the accommodating chamber through the central channel. These liquid objects can play a buffering role, and play a role in increasing friction and slowing down the reset speed during the reset process of the reset torsion spring, thereby achieving the effect of automatic slow closing of the door, effectively avoiding damage to the door frame by the door leaf during the automatic closing process, and effectively reducing or even eliminating the noise caused by the collision between the two, and having a good user experience.

[0015] In some embodiments, the rotating device with a buffering function further comprises a blocking member for blocking the central channel, so that the central channel can be closed after the resistance oil is injected to prevent backflow.

[0016] In some embodiments, the rotating device with a buffering function further includes an adjusting member, which is mounted on the first mounting member and cooperates with the first connector. Thus, the adjusting member can adjust the position of the first connector so that the first connector moves relative to the second mounting member, changes the pressure of the liquid in the accommodating chamber, and deforms the reset torsion spring, thereby adjusting the reset speed of the reset torsion spring to meet different usage requirements.

[0017] In some embodiments, the rotating device with a buffer function further includes a locking nut, the adjusting member is an adjusting screw threadedly matched with the first mounting member, and the locking nut matches the adjusting member. Thus, the adjusting screw can be adjusted conveniently and quickly, and after being adjusted to the right position, it is locked by the locking nut to prevent the adjusting member from shifting during use.

[0018] In some embodiments, a limiting structure capable of limiting the rotation of the first connector in the axial direction is provided on the second mounting member.

[0019] In some embodiments, the limiting structure is a groove-type limiting structure. Therefore, the limiting structure in the form of a groove-type limiting structure is simple, low-cost, and can play an effective limiting role.

[0020] In some embodiments, the rotating device with a buffer function further includes a slider, which is detachably mounted on the first mounting member and forms a slot-type limiting structure together with the first mounting member, and a threaded hole is provided on the slider to cooperate with the thread of the locking nut. Thus, the provision of the slider facilitates the detachability of the shaft-shaped component and the second mounting member, and facilitates maintenance or replacement.

[0021] In some embodiments, the rotating device further includes a locking screw, which cooperates with the slider and the first mounting member to lock the slider to the first mounting member.

[0022] According to another aspect of the utility model, a top and bottom hinge is provided, including an upper rotating device and a lower rotating device which are used together and are respectively installed at the upper and lower ends of the door body. The upper rotating device adopts the above-mentioned rotating device with buffering function.

[0023] Therefore, the utility model provides a new structure of the top and bottom hinge, which is composed of an upper rotating device and a lower rotating device. The upper rotating device applies the above-mentioned rotating device with buffering function, which can realize slow and automatic door closing.

[0024] According to another aspect of the utility model, a door is provided, comprising the above-mentioned top and bottom hinges, a door leaf and a door frame, wherein the upper and lower ends of the door leaf are rotatably mounted on the door frame via an upper rotating device and a lower rotating device respectively.

[0025] Therefore, the utility model provides a door with a completely new structure, which applies the above-mentioned top and bottom hinges, and the upper rotating device has an automatic slow resetting function, which can realize an automatic slow door closing action.

DETAILED DESCRIPTION

[0036] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0037] Figures 1 to 7The figure schematically shows a rotating device with a buffering function according to an embodiment of the utility model.

[0038] like Figures 1 to 7 As shown, the rotating device with buffering function at least comprises:

[0039] A first mounting member 1, mounted on a stationary object;

[0040] A second mounting member 2, mounted on the moving object;

[0041] The shaft-shaped component 3 is sleeved on the second mounting member 2 and matched with the first mounting member 1;

[0042] The shaft assembly 3 includes a tubular member 31, a first connector 32, a second connector 33 and a return torsion spring 34. The tubular member 31 is sleeved in the second mounting member 2. The first connector 32 and the second connector 33 are respectively mounted at both ends of the tubular member 31. The return torsion spring 34 is mounted in the tubular member 31 and its two ends are respectively matched with the first connector 32 and the second connector 33. The second connector 33 is connected to the second mounting member 2. One end of the first connector 32 away from the return torsion spring 34 is limitedly matched with the first mounting member 1.

[0043] The first connector 32, the second connector 33, the tubular member 31 and the second mounting member 2 together form a receiving chamber 10;

[0044] A central channel 321 for injecting a liquid object capable of slowing down the return of the return torsion spring 34 and communicating with the accommodating cavity 10 is opened at the center of the first connector 32 .

[0045] The first connector 32 is provided with a first protrusion 322 at one end close to the return torsion spring 34, and a first opening is provided in the middle of the first protrusion 322 to be limitedly matched with the first torsion spring end of the return torsion spring 34. The second connector 33 is provided with a second protrusion 331 at one end close to the return torsion spring 34, and a second opening is provided in the middle of the second protrusion 331 to be limitedly matched with the second torsion spring end of the return torsion spring 34. Thus, quick assembly is facilitated.

[0046] The first mounting member 1 includes a first flat plate portion 11 and a base portion 12. The first flat plate portion 11 is provided with a plurality of first mounting holes 111. The first mounting member 1 is fixedly connected to a stationary object by the cooperation of the first mounting holes 111 and fasteners such as screws. The second mounting member 2 includes a second flat plate portion 21 and a sleeve portion 22. The second flat plate portion 21 is provided with a plurality of second mounting holes 211 and an adjustment hole 212. The shaft-shaped component 3 is sleeved on the sleeve portion 22.

[0047] The first connecting head 32 is fixedly connected to the tubular member 31 by seamless welding, and the second connecting head 33 is fixedly connected to the sleeve portion 22 of the second mounting member 2 by seamless welding.

[0048] There is a gap between the tubular member 31 and the second connector 33, and a notch is provided at one end of the tubular member 31 close to the second connector 33. Thus, the first connector 32 can be easily moved and subsequently adjusted.

[0049] The rotating device with buffer function also includes a plugging member 4 for plugging the central channel 321. Thus, the central channel 321 can be closed after the resistance oil is injected to prevent backflow. The central channel 321 of this embodiment can be provided with an internal thread, and the plugging member 4 can be provided with an external thread to achieve the detachability of the plugging member 4.

[0050] The rotating device with buffer function also includes an adjusting member 5, which is mounted on the first mounting member 1 and cooperates with the first connector 32. Thus, the adjusting member 5 can adjust the position of the first connector 32, so that the first connector 32 moves relative to the second mounting member 2, changes the pressure of the liquid in the accommodating chamber 10, and deforms the reset torsion spring 34, thereby realizing the adjustment of the reset speed of the reset torsion spring 34 to meet different usage requirements.

[0051] The rotating device with buffer function also includes a locking nut 6, and the adjusting member 5 is an adjusting screw threadedly matched with the first mounting member 1, and the locking nut 6 matches with the adjusting member 5. Therefore, the adjusting screw can be adjusted conveniently and quickly, and after being adjusted to the right position, it is locked by the locking nut 6 to prevent the adjusting member 5 from being displaced during use.

[0052] The adjusting member 5 can be tightened or loosened. When tightened, the adjusting member 5 will press against the end of the first connecting head 32, so that the first connecting head 32 moves in the direction close to the return torsion spring 34 to increase the hydraulic pressure in the accommodating chamber 10, increase the resistance, and compress the return torsion spring 34 at the same time, so that the return speed of the return torsion spring 34 slows down, achieving the effect of slowly closing the door or even keeping it in the specified position; conversely, when loosened, the first connecting head 32 moves in the direction away from the return torsion spring 34 to reduce the hydraulic pressure in the accommodating chamber 10, reduce the resistance, and the return speed of the return torsion spring 34 becomes faster.

[0053] The second mounting member 2 is provided with a limiting structure 20 capable of limiting the first connector 32 from rotating in the axial direction.

[0054] The limiting structure 20 is a groove-shaped limiting structure. Therefore, the limiting structure 20 in the form of a groove-shaped limiting structure is simple, low-cost, and can play an effective limiting role. Specifically, the limiting structure 20 can be a regular hexagonal groove, and one end of the first connector 32 that cooperates with the limiting structure 20 is a hexagonal column.

[0055] The rotating device with buffer function also includes a slider 7, which is detachably mounted on the first mounting member 1 and forms a slot-shaped limiting structure together with the first mounting member 1. The slider 7 is provided with a threaded hole that is threadedly matched with the locking nut 6. Therefore, the arrangement of the slider 7 facilitates the detachability of the shaft-shaped component 3 and the second mounting member 2, and facilitates maintenance or replacement.

[0056] Specifically, the slider 7 of this embodiment can be movably mounted on the base portion 12 of the first mounting member 1. A limiting groove 122 is provided on the base portion 12, and limiting edges 71 are provided on both sides of the slider 7 to limit the limiting groove 122. A first limiting half groove 72 is provided on the slider 7, and a second limiting half groove 123 is provided at the bottom of the limiting groove 122. When the slider 7 is mounted on the base portion 12, the first limiting half groove 72 and the second limiting half groove 123 are enclosed together to form a groove-shaped limiting structure.

[0057] The rotating device further comprises a locking screw 8, which cooperates with the slider 7 and the first mounting member 1 to lock the slider 7 to the first mounting member 1. The base portion 12 on both sides of the second limiting half groove 123 is provided with connecting holes 121 for the locking screw 8 to pass through.

[0058] The utility model provides a rotating device with a brand-new structure, and the working principle of the rotating device is as follows:

[0059] The first mounting member 1 is mounted on a stationary object such as a door frame, and the second mounting member 2 is mounted on a movable object such as a door leaf. Since the top of the first connecting head 32 is limited by the first mounting member 1, when the door leaf moves, it will drive the second mounting member 2 and the second connecting head 33 connected to the second mounting member 2 to rotate together under the action of external force. The rotation of the second connecting head 33 drives the reset torsion spring 34 to deform. After the external force disappears, the reset function of the reset torsion spring 34 drives the second mounting member 2 to reset, thereby realizing the automatic closing of the door leaf. The rotating device of the utility model can inject liquid objects such as resistance oil or damping grease into the accommodating chamber 10 through the central channel 321. These liquid objects can play a buffering role, and play a role in increasing friction and slowing down the reset speed during the reset process of the reset torsion spring 34, thereby achieving the effect of automatic slow closing of the door, effectively avoiding damage to the door frame by the door leaf during the automatic closing process, and effectively reducing or even eliminating the noise caused by the collision between the two, and having a good user experience.

The upper rotating device 100 adopts the above-mentioned rotating device with buffering function.

[0062] Therefore, the utility model provides a new structure of the top and bottom hinge, which is composed of an upper rotating device 100 and a lower rotating device 200. The upper rotating device 100 uses the above-mentioned rotating device with buffer function, which can realize slow automatic closing of the door. The lower rotating device 200 is a prior art, and the specific structure is referred to the Chinese utility model patent with announcement number CN220687062U, which will not be described in detail here.
