The utility model relates to a rotary buffer device which is arranged between two mutually pivoted objects. The rotation buffer device is a sheet-shaped buffering element and is arranged on one object, the buffering element can be contacted with the other object when the object is rotating, the buffering element is a rubber buffering element, the thickness can be from thin to thick according to the rotating direction. The utility model can increase the friction resistance in rotating and reduce the rotation rate.

Description

A kind of rotation buffer unit

Technical field

The utility model relates to a kind of rotation buffer unit, is applied to two objects articulating mutually, particularly relate to when rotated a kind of, improve rotation frictional resistance, reduce the rotation buffer unit of the speed of rotation.

Background technology

Because in the process that moves of object, tend to because careless, and object is impacted, cause damage, thus there are many kinds to be applied to the not design of object of the same race at present, so that object is in the process that moves, the unlikely bump and damaging.These technology be exposed in the Taiwan patent gazette No. 177591, No. 527074, No. 534555 and No. 562320 patent case in.

Disclose a kind of yielding rubber mat structure improvement of plain type aluminium door and window in No. 177591 patent case of Taiwan patent gazette, its multilayer umbrella shape pushing and drawing shape dome that cone shape cushion pad of ladder type is extended into aluminium door and window of moving into clashes into part mutually, so in the time can aluminium door and window being clashed into mutually by cushion pad, the sound that unlikely generation is bigger and distortion.

Disclose a kind of folding buffer unit of collapsible mobile phone in No. 527074 patent case of Taiwan patent gazette, mainly be to slow down the speed that loam cake flicks, loam cake is flicked with speed slowly, and unlikely when loam cake flicks, cause the damage of mobile phone internal wiring.

Disclose a kind of cover plate rotating shaft buffer gear in No. 534555 patent case of Taiwan patent gazette, be applied to optical scanner, this patent case mainly is sheathed on the fixed axis in hole in the main body by torque spring, and an end of torque spring wears to the file cover plate, the other end then is positioned at the hole, so can reach file cover plate rotation move to its with intersubjective angle differ about 90 spend angle the time, torque spring end in the hole just leans the roof face in the hole, to produce elastic torsion as buffering.

Disclose a kind of buffering hinge axle construction of cover-lifting type mobile phone casing in No. 562320 patent case of Taiwan patent gazette, be applied to mobile phone, when being started or being closed, have the effect of hinge buffering with flip at hand set machine shell.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of rotation buffer unit, with when two objects that articulate mutually rotate, improves the frictional resistance of rotation, reduces the speed of rotation.

To achieve these goals, the utility model provides a kind of rotation buffer unit, be installed between two objects of mutual pivot joint, its characteristics are, described rotation buffer unit is a sheet of bolster and is arranged on the described object that described bolster contacts another described object when rotating with described object.

Above-mentioned rotation buffer unit, its characteristics are that described bolster is the rubber bolster.

Above-mentioned rotation buffer unit, its characteristics are that the thickness of described bolster is thinned to thick according to its direction of rotation certainly.

Above-mentioned rotation buffer unit, its characteristics are, also are provided with an extrusion that is attached at its surface on described bolster, and the thickness of described extrusion is according to the direction of rotation of described bolster, from thick to approaching.

Above-mentioned rotation buffer unit, its characteristics are that described extrusion is a hollow compressive deformation structure, and inside is provided with the flowable air of pressurized.

Above-mentioned rotation buffer unit, its characteristics are, also be provided with positioning piece in described object, and described keeper are positioned at around the part of described bolster.

Above-mentioned rotation buffer unit, its characteristics are that the length of described bolster is short to length certainly according to its direction of rotation.

Effect of the present utility model is to improve the frictional resistance of rotation, reduces the speed of rotation.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

Embodiment

As Figure 1A, 1B, be the disclosed a kind of rotation buffer unit of the utility model, be applied to object 10 and another object 20 of pivot joint mutually, this sentences audio and video player as an illustration, this device includes bolster 31, extrusion 32 and keeper 33, wherein the material of bolster 31 is a rubber, and it is a sheet, and be arranged at one object 10, the thickness of bolster 31 is according to its direction of rotation, approach end 311 and thick end 312 from being thinned to thick being respectively, and the thin end 311 of bolster 31 is short to length certainly to the length of thick end 312.

Extrusion 32 is attached at the surface of the appropriate position of bolster 31, the thickness of extrusion 32 is according to the direction of rotation of bolster 31, be respectively thick end 321 and approach end 322 to thin from thick, extrusion 32 inside are hollow, with when another object 20 pushes, inner air is flowed to the place of not being squeezed of extrusion 32.

Keeper 33 is positioned at object 10, and keeper 33 is positioned at around the part of bolster 31, is attached at the usefulness of the location of bolster 31 so that bolster 31 to be provided.

When bolster 31 and extrusion 32 were attached at object 10, the action that attaches was done in the position that can be limited according to keeper 33, sees also the schematic diagram of the present utility model shown in Figure 1A.

In use, then see also Fig. 2 A, 2B, 2C, 2D, 2E, be action diagram of the present utility model, make object 10 relative another object 20 rotations (thrusts that can pass through the deadweight of object 10 or promote object 10 earlier, and cause object 10 to rotate), therefore another object 20 just can begin to touch the thin end 311 at thin thickness place of the bolster 31 that is attached at object 10 (length of bolster 31 is short herein, the area that another object 20 is touched is little), and in the process of object 10 rotations, another object 20 can touch the thick end 312 at the thick place of thickness of bolster 31 gradually, and (length of bolster 31 is long herein, the area that another object 20 is touched is big), certainly be arranged at the extrusion 32 of appropriate location, also can be because of being pushed by another object 20, and make its inner air flows to not being extruded the place, so bolster 31 of the present utility model and extrusion 32 can be when object 10 rotations, contact another object 20, buffering is provided, and the frictional resistance of raising rotation, reduce the speed of rotation, and when object 10 rotation just, touch the thin end 311 at the thin thickness place of bolster 31 earlier because of another object 20, so its speed of rotation is very fast, but touch the thick end 321 of the thick end 312 at the thick place of thickness of bolster 31 and extrusion 32 and thin end 322 o'clock gradually at object 10, its speed of rotation can be slack-off gradually, so that object 10 after rotary course finishes, does not have the situation of impact damage.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the utility model claim.
