Abstract

The utility model discloses a buffer for a hinge, which is composed of a buffering rod 1, a fixed body 2 and an adjusting screw 3. The shape and the size of the existing hinge can be changed to be directly arranged and used on a corresponding hinge, and the self function of the hinge can not be affected. When a door and a window are closed, the shock kinetic energy of the door and the window can be absorbed. The shock sound can be eliminated when the door and the window are closed. The shock damage phenomenon of the door and the window can be stopped. The buffer has the advantages of light weight, compactness, easy assembly and disassembly, and low cost.

Description

The snubber that hinge is used

Technical field

The utility model relates to the snubber that the accessory of hinge, particularly hinge are used.

Background technology

Be used for the hinge of door, window, generally all be not with buffer, when closing door, window, because stressed relation, can produce doorframe, window frame and impact, not only can produce bigger impact sound, and repeated impact doorframe, window frame finally can cause the damage of door, window.

The utility model content

The purpose of this utility model just is to provide a kind of can play cushioning effect at door, when window is closed, and avoids the snubber that the hinge that doorframe, window frame generation are impacted is used.

For reaching above-mentioned purpose, snubber of the present utility model is made up of damper bar, fixed body, set screw.Have groove and through hole on the fixed body, groove shapes and hinge bodies match, the through hole size is fit to damper bar and packs into, damper bar and set screw lay respectively at the two ends of the through hole on the fixed body, set screw heads on the afterbody of damper bar, the plug of damper bar stretches out outside fixed body, and position corresponding with the hinge function adjusting device on the fixed body also has groove.

The utility model is the accessory of hinge, need be installed on the hinge bodies before using, be installed on door-plate, the doorframe with hinge again, when closing the door certain position, door-plate pushes up the plug of snubber damper bar, and damper bar absorbs the impact kinetic energy of door-plate, and the movement velocity of slowing down door-plate stops to put in place up to door-plate, the set screw of the shell afterbody by regulating damper bar can be regulated plug and be stretched out length outside fixed body, to guarantee that door-plate stops at the just in time position of complete shut-down at closing time.After opening the door, the damper bar pressure disappears, and the mechanism that returns back to top of damper bar inside can make damper bar be returned to reset condition, to accept buffering next time.

From principle of the present utility model and using method as can be seen, adapted the door of the utility model snubber, window when closing, can not produce and impact, not only eliminate the impact sound when closing door, window, and stop the impact failure phenomenon of door, window doorframe, window frame.

The utility model is described in more detail below in conjunction with the drawings and specific embodiments.

Specific embodiment

Fig. 1 to Fig. 6 has provided a specific embodiment of the snubber that the utility model hinge uses, and it is made up of damper bar 1, fixed body 2, set screw 3.Have groove 4 and through hole on the fixed body 2, the shape of groove 4 is U-shapeds that the body with hinge 6 matches, like this fixed body 2 can be more reliably installing and locating to hinge 6, a stuck point is arranged in the centre of U-shaped groove 4, when fixed body 2 is installed on the hinge 6, block the body of hinge 6, play positioning action.The through hole size of fixed body 2 is fit to damper bar 1 and packs into, damper bar 1 and set screw 3 lay respectively at the two ends of through hole, damper bar 1 is installed in the through hole of fixed body 2, the plug 8 of damper bar 1 stretches out outside fixed body 2, the front of damper bar 1 has the salient point of fixed body 2 to block, play the effect of clamping, the back has set screw 3 to locate, and the variation of front and back position can not take place when stressed restriction damper bar 1; The through hole other end has internal thread, set screw 3 forms with through hole at this and is threaded, the afterbody that set screw 3 heads on damper bar 1 positions damper bar 1, the plug 8 of damper bar 1 is stretched out outside fixed body 2, set screw 3 is regulated the effect of buffering effect in addition simultaneously, change the extension elongation of plug 8 by regulating damper bar 1 at the front and back position of fixed body 2 inner chambers, to obtain best buffering effect.

Above-mentioned damper bar 1 can adopt fluid pressure type, vapour-pressure type or spring etc., what Fig. 7 provided is the schematic diagram of the damper bar 1 of oil hydraulic type, oil hydraulic type is a kind of of fluid pressure type, the damper bar 1 of this oil hydraulic type comprises sound absorber 7, plug 8, shell 9, oil pocket 10, piston 11, oil pocket 12, spring 13, oil pocket 10 communicates with oil pocket 12, be filled with oil in oil pocket 10 and the oil pocket 12, ordinary circumstance oil is full of, when being subjected to impacting external force, external force pressure sound absorber 7, by plug 8 piston 11 is moved to oil pocket 12 directions, oil pressure increases in the oil pocket 12, force oil wherein to flow to oil pocket 10 to keep the pressure balance of oil pocket 10 and oil pocket 12, while piston 11 holddown springs 13, the kinetic energy of external impacts in fact is converted into spring potential energy, owing to flowing of oil in this process is slower, the translational speed of piston 11 also is slow, therefore the impact of external force has been played the effect of buffering.After external force disappeared, the potential energy of spring 13 discharged, and headed on piston 11 and moved to oil pocket 10 directions, and oil pressure increases in the oil pocket 10, forced wherein oil to flow to oil pocket 12 keeping the pressure balance of oil pocket 10 and oil pocket 12, discharged fully until the potential energy of spring 13.The damper bar of other vapour-pressure type, spring also is essentially identical principle.

The sound absorber that head overlapped 7 of the plug 8 on the damper bar 1 should adopt rubber-like, plastic materials manufacturing, like this at closing time, the impact force of door-plate remakes on the plug 8 of using damper bar 1 by sound absorber 7, in the moment that door-plate contacts with sound absorber 7, sound absorber 7 pressurizeds can produce slight deformation, can effectively absorb impact kinetic energy, reduce noise, reduce the impact force of door-plate the plug 8 of the utility model snubber.

Position corresponding with the function adjusting device of hinge 6 on fixed body 2 also has groove 5, hinge 6 according to different structure, groove 5 on the fixed body 2 can be opened 1,2 or more a plurality of, the function adjusting device that can not cover hinge 6 with fixed body 2 is advisable, can allow the user like this when not removing fixed body 2, also can arbitrarily adjust the position and the function of hinge 6.

For make the utility model snubber easily installing and locating on hinge 6, centre at groove 4 is provided with elastic fastening hook, elastic fastening hook matches with breach on the hinge bodies, when fixed body 2 is installed on the hinge 6, elastic fastening hook blocks the breach on the hinge bodies, can position fixed body 2 easily, fixed body 2 firmly is fixed on the hinge 6, such structure removes also very convenient simultaneously.Certainly, above-mentioned easily detachable location structure is formed by salient point that is positioned at groove 4 centres and the breach on the hinge bodies, salient point matches with breach on the hinge bodies, and when fixed body 2 was installed on the hinge 6, salient point just in time blocked the breach on the hinge bodies.

The utility model snubber can adopt plastics as main manufactured materials, merrily and lightheartedly small and exquisite, save cost, its structure does not influence the function of hinge itself yet, do not need to change the profile and the size of existing hinge, can be used as an accessory of hinge, be directly installed on the corresponding hinge and use, mount and dismount all more convenient.
