Description

Technical Field

[0001] The utility model relates to the field of buffers, more specifically to a swirl-type guideable buffer. Background Art

[0002] With the improvement of people's living standards, buffers are becoming more and more widely used in daily applications due to their impact resistance and low noise performance, such as toilet seat covers and door leaves.

[0003] There are many existing technologies for buffers, such as:

[0004] Chinese Patent Publication No. CN112021979A discloses a rotary buffer, comprising: a sleeve, a rotating shaft, an oil flow space, a blade, and an adjusting member. The blade is rotatably engaged with the end of the rotating shaft, and the side of the blade has a wing. The wing and the rotor plate cooperate to switch between a closed state and an open state to allow the damping oil to flow, and a limiting structure is provided between the blade and the rotating shaft. The present application adopts a wing and a rotor plate to cooperate to switch between a closed state and an open state, thereby driving the damping oil to flow in a damping state or a non-damping state. The rotor plate and the wing are arranged in an upper and lower structure, which reduces the overall thickness of the rotor plate part and increases the angle that the rotating shaft can rotate; thereby achieving a larger opening angle of the toilet lid. The adjusting member can cooperate with the blade structure to adjust the slow-down time of the buffer. At the same time, the damping oil flow channel formed by the staggered wing and the rotor plate is larger, which can achieve rapid oil circuit reflux.

[0005] Chinese Patent Publication No. CN203506582U discloses a rotary damper that is easy to assemble. The damper comprises a barrel and a shaft. One end of the shaft is mounted within the inner cavity of the barrel, while the other end extends outside the barrel. A wing tangent to the inner wall of the barrel is provided on the shaft. The shaft, wing, and barrel define an oil chamber for filling damping oil. The wing is provided with an oil discharge port. A slot is provided on the outer wall of the barrel adjacent to the wing. A movable sealing piece is inserted into the slot, the outer end of which can swing relative to the slot to close or open the oil discharge port. When the barrel rotates clockwise, the movable sealing piece separates from the wing, opening the oil discharge port. When the barrel rotates counterclockwise, the movable sealing piece presses against the wing, sealing the oil discharge port. This utility model has a good damping effect, the movable sealing piece is not easily detached, the product is of good quality, and the structure is simple.

[0006] Most of the buffers on the existing technology market are damping devices composed of a rotating shaft and a sleeve. When the rotating shaft rotates, the blades open and close to form a rapid or slow oil-passing process, thereby producing a damping and buffering effect. However, the existing buffers require a boosting force to rotate, which is inconvenient to guide the buffer to rotate and reset.

[0007] In view of this, the utility model provides a swirl-type guideable buffer. Summary of the Invention

[0008] The utility model provides a swirl-type guideable buffer, which comprises a cylinder body, a disc fixedly connected to the top of the cylinder body, a rotating assembly movably connected to the outer wall of the disc, and a disassembly assembly fixedly connected to the top of the rotating assembly;

[0009] A rebound component is movably connected inside the chute at the top of the disc, a swirl component is fixedly connected between the end of the rebound component passing through the disc and the inner wall of the rotating component, and the swirl component is movably connected inside the disc.

[0010] As a further improvement of the present technical solution, the rotating assembly includes a sleeve, which is movably connected to the outer wall of the cylinder body, and a swivel is fixedly connected to the inner wall of the sleeve near the bottom, and the swivel is movably connected to the inside of the slide groove of the outer wall of the disc, and the inner wall of the sleeve is fixedly connected to the swirl assembly, and the top of the sleeve is fixedly connected to a disassembly and assembly assembly, and the rotating assembly is used to rotate the electric swirl assembly inside the disc.

[0011] As a further improvement of the present technical solution, the disassembly and assembly component includes a support rod, which is fixedly connected to the top of the sleeve, and the inner wall of the support rod is fixedly connected with a bolt. The disassembly and assembly component is used to facilitate connection with the rotating shaft that requires buffering.

[0012] As a further improvement of the present technical solution, the swirl component includes an axis, which is movably connected to the inside of the disc, and a turntable is fixedly connected to the bottom of the axis. The turntable is movably connected to the inside of the disc, and the axis passes through the outer wall of the top of the disc and is fixedly connected to blades. Both ends of the blades are fixedly connected to the inner wall of the sleeve, and the bottom of the blades is fixedly connected to a rebound component. The swirl component is used to buffer and rebound the rotation of the rotating component.

[0013] As a further improvement of the present technical solution, the rebound component includes a slider, which is fixedly connected to the bottom of the blade. The slider is located inside the slide groove at the top of the disc. An elastic part is fixedly connected between one end of the slider and one end of the disc slide groove. The rebound component is used to drive the swirl component to rebound and rotate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By installing the disassembly and assembly component on the rotating shaft that needs buffering, the rotation of the rotating shaft drives the rotating component to rotate on the disc, and at the same time drives the swirl component to rotate inside the disc. The rotation of the swirl component drives the rebound component to slide inside the disc, and the stretching and rebound of the rebound component drives the swirl component to rotate in the opposite direction, thereby driving the rotating component and the rotating shaft to rotate and reset.

DETAILED DESCRIPTION

[0024] like Figure 1-6 As shown, the device includes a barrel 1, a disc 11 is fixedly connected to the top of the barrel 1, a rotating assembly 12 is movably connected to the outer wall of the disc 11, and a disassembly assembly 13 is fixedly connected to the top of the rotating assembly 12;

[0025] A rebound component 15 is movably connected to the inner portion of the chute at the top of the disc 11. A swirl component 14 is fixedly connected between the end of the rebound component 15 that passes through the disc 11 and the inner wall of the rotating component 12. The swirl component 14 is movably connected to the inside of the disc 11.

[0026] First, the specific structure of the rotating assembly 12 is disclosed. The rotating assembly 12 includes a sleeve 120, which is movably connected to the outer wall of the barrel 1, and a swivel 121 is fixedly connected to the inner wall of the sleeve 120 near the bottom. The swivel 121 is movably connected to the inner groove of the outer wall of the disc 11. The inner wall of the sleeve 120 is fixedly connected to the swirl assembly 14, and the top of the sleeve 120 is fixedly connected to the disassembly assembly 13. The rotating assembly 12 is used to rotate the electric swirl assembly 14 inside the disc 11. The rotation of the sleeve 120 drives the swivel 121 to rotate inside the disc 11. The sleeve 120 is clamped to the outer wall of the disc 11 by the swivel 121, which makes it convenient for the sleeve 120 to drive the blades 142 to rotate.

[0027] According to the above disclosure of the specific structure of the disassembly assembly 13, the disassembly assembly 13 includes a support rod 130, which is fixedly connected to the top of the sleeve 120. The inner wall of the support rod 130 is fixedly connected with a bolt 131. The disassembly assembly 13 is used to facilitate connection with the rotating shaft that needs buffering. By tightening the bolt 131 on the outer wall of the rotating shaft that needs buffering, the position between the support rod 130 and the rotating shaft is fixed. The support rod 130 is driven to rotate by the rotation of the rotating shaft, and the sleeve 120 is driven to rotate by the support rod 130;

[0028] According to the above disclosure of the specific structure of the swirl assembly 14, the swirl assembly 14 includes an axis 140, which is movably connected to the inside of the disc 11. The bottom of the axis 140 is fixedly connected to a turntable 141, and the turntable 141 is movably connected to the inside of the disc 11. The axis 140 passes through the outer wall of the top of the disc 11 and is fixedly connected to blades 142. Both ends of the blades 142 are fixedly connected to the inner wall of the sleeve 120. The bottom of the blades 142 is fixedly connected to the rebound assembly 15. The swirl assembly 14 is used to buffer and rebound the rotation of the rotating assembly 12. The rotation of the blades 142 drives the axis 140 to rotate, and the axis 140 is clamped in the inside of the disc 11 through the turntable 141. At the same time, the rotation of the blades 142 drives the slider 150 to move inside the slide groove at the top of the disc 11, so that the slider 150 drives the blades 142 to rotate and reset.

[0029] According to the above disclosure of the specific structure of the rebound component 15, the rebound component 15 includes a slider 150, which is fixedly connected to the bottom of the blade 142. The slider 150 is located inside the slide groove at the top of the disc 11, and an elastic member 151 is fixedly connected between one end of the slider 150 and one end of the slide groove of the disc 11. The rebound component 15 is used to drive the swirl component 14 to rebound and rotate. The slider 150 rotates inside the slide groove at the top of the disc 11, driving the elastic member 151 to stretch inside the slide groove at the top of the disc 11, and the slider 150 is reset by the elastic force of the elastic member 151 itself. It is convenient for the slider 150 to drive the blade 142 to rotate in the opposite direction, reset the rotation of the sleeve 120, and thus reset the rotation of the rotating shaft.

[0030] The improvement of this embodiment is that the position between the support rod 130 and the rotating shaft is fixed by tightening the bolt 131 on the outer wall of the rotating shaft that needs to be buffered, and the support rod 130 is driven to rotate by the rotation of the rotating shaft, and the shaft sleeve 120 is driven to rotate by the support rod 130, and the rotating ring 121 is driven to rotate inside the disc 11 by the rotation of the shaft sleeve 120, and the shaft sleeve 120 is clamped to the outer wall of the disc 11 by the rotating ring 121, so that the shaft sleeve 120 drives the blade 142 to rotate, and the shaft center 140 is driven to rotate by the rotation of the blade 142, and the shaft center 140 is clamped by the rotating disc 141. Inside the disc 11, the blade 142 rotates and drives the slider 150 to move inside the chute at the top of the disc 11, so that the slider 150 drives the blade 142 to rotate and reset. The slider 150 rotates inside the chute at the top of the disc 11, driving the elastic member 151 to stretch inside the chute at the top of the disc 11. The elastic force of the elastic member 151 rebounds and drives the slider 150 to reset. The slider 150 drives the blade 142 to rotate in the opposite direction, thereby resetting the rotation of the sleeve 120 and thus resetting the rotation of the rotating shaft.

[0031] In summary, the working principle of this solution is as follows:

[0032] The disassembly assembly 13 is installed on the rotating shaft that needs buffering, wherein the disassembly assembly 13 fixes the position between the support rod 130 and the rotating shaft by tightening the bolt 131 on the outer wall of the rotating shaft that needs buffering, and the support rod 130 is driven to rotate by the rotation of the rotating shaft, and the shaft sleeve 120 is driven to rotate by the support rod 130, and the rotating assembly 12 is driven to rotate on the disc 11 by the rotation of the rotating shaft, and the swirl assembly 14 is driven to rotate inside the disc 11 at the same time, wherein the rotating assembly 12 drives the swirl ring 121 to rotate inside the disc 11 through the rotation of the shaft sleeve 120, and the shaft sleeve 120 is clamped on the outer wall of the disc 11 through the swirl ring 121, so that the shaft sleeve 120 drives the blade 142 to rotate, and the rebound assembly 15 is driven to slide inside the disc 11 through the rotation of the swirl assembly 14, wherein the swirl assembly 14 drives the blade 142 to rotate.
