Summary of the invention
The utility model technical issues that need to address are, existing timber at closing time easily and doorframe occur to clash into and produce noise, thus provide a kind of timber with noise reduction effect.
To achieve these goals, the utility model adopts following technical scheme: a kind of roller type noise abatement timber, comprises the body being fixed on the timber on doorframe with hinge, also comprise roller; Described roller is provided with axial roller shaft, and the direction of roller shaft is parallel to the width of described body; Described body is provided with in the position near ground the roller breach that Open Side Down, and described roller breach is provided with roller axis hole on the width of described body; Described roller shaft and described roller axis hole are rotationally connected; The top of described roller breach is fixed with deceleration blade.
In this programme, be provided with a roller in the bottom of the body of timber near ground location, the width of the parallel body of axle of this roller, makes roller can rotate along with the folding of body.The top of roller is provided with deceleration blade, applies frictional force in order to pair roller.When timber body is in moving process, roller continues to rotate, and the pair roller applying frictional force that deceleration blade continues is slowed down, and effectively can slow down the running speed of timber body, reduces the chance of body knocking door case, thus decreases the noise clashing into and produce; Even if clashing into appears in timber body and doorframe, also a large amount of kinetic energy can be reduced because the speed of body is greatly reduced, thus the noise produced when alleviating shock.
As preferably, described ground is for being obliquely installed, within the scope of described roller rolling track, more higher at the projected position on ground close to described doorframe.Before by knocking door case, kinetic energy is exhausted to greatest extent in order to allow the body of timber, in this programme, ground design is become slope, away from doorframe projected position is low level, more higher close to doorframe projected position, make roller when rotating more close to doorframe projected position along with body, the support force being subject to sloping floor is stronger, the frictional force be converted between ground and roller is also stronger, also stronger to the inhibition of this displacement body, thus further minimizing timber impinges upon the noise that doorframe produces.
As preferably, described roller axis hole is slotted hole, and bearing of trend is the short transverse being parallel to described body.In present design, in order to keep pushing more easily feel in the position away from doorframe, avoid too heavy and cause door to be difficult to normally be promoted and close, roller axis hole is designed to the slotted hole extended along the short transverse of body, roller shaft not only can be rotated along axis, can also slide up and down along the pass of slotted hole.When the projected position of body away from doorframe, roller shaft is in the below of roller axis hole because roller is subject to gravity, away from the deceleration blade of top, the support force on ground cannot be converted into frictional force and rotate to hinder roller, now roller can freely rotate, and user can light sliding door; When the body of door is more and more when the projected position of doorframe, roller is subject to the support force on ground, along the roller axis hole upwards displacement of slotted hole, move closer to and be close to deceleration blade, time now, the frictional force of deceleration blade or ground pair roller is all more and more stronger, and the decelerating drag of opposite house is increasing, the kinetic energy consuming door gets more and more, the chance of door knocking door case further reduces, even if clash into, the noise sent is also more and more less.
As preferably, described roller breach is located at the side that described body is not provided with hinge.Roller is arranged on the side away from hinge, namely has the longer arm of force, can when stressed identical obtain more excellent slowing effect.
As preferably, it is characterized in that, described deceleration blade is elastic material.Elastic material can at roller upwards in the process of bottom offset, automatic tightness regulating degree, more loose elastomeric material, and less with the contact surface of roller, frictional force is also less, and tight elastomeric material, the contact surface of pair roller is larger, and the frictional force produced is also larger.The body of timber is more close to the projected position of doorframe, the position in roller breach of roller is higher, and the deformation extent that jack-up bullet deceleration blade produces is larger, and the level of tightness of elastomeric material is larger, also larger with the contact surface of roller, the slowing effect of realization is better.
In sum, the beneficial effects of the utility model are: have good avoiding or consumption to the noise that timber knocking door case sends.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described.
Embodiment as shown in Figure 1, a kind of roller type noise abatement timber, comprises the body 1 of timber, and upper and lower two hinges 3 that pass on left of body are fixed on doorframe 2, and the right side of body is provided with door lock 4 and handle 5.The lower right-hand side of timber body, near the position on ground 9, is provided with a roller breach 11, as shown in Figure 2, the opening direction of this roller breach is downward, in roller breach, the sidewall of the left and right sides is equipped with roller axis hole 8, the slotted hole of roller axis hole to be bearing of trend be above-below direction.Roller 6 is provided with axial roller shaft 7, rolls respectively and be connected in two roller shafts in left and right in two ends of roller shaft, while roller can be pivoted, and can also upper and lower displacement in the upper and lower spacing scope of roller axis hole.The top of roller breach, is fixed with deceleration blade 12, and deceleration blade is that elastic material is made, and uses quality of rubber materials in this example.Mate with timber, ground is obliquely installed, and the projected position of doorframe on ground is highest order, in the rolling track of roller, more lower away from this position, more higher close to this position.
A kind of roller type noise abatement timber of the present utility model, as shown in Figure 3, when being in open mode, timber body is away from doorframe projected position, and the ground at roller track place is in low level, and roller is synchronously in low level, the support force of ground, below pair roller cannot be converted into the frictional force be applied on roller, leave gap between top deceleration blade and roller, also cannot produce frictional force by pair roller, the now rolling of roller is freely expedite.When timber body is pushed to fastening position gradually, namely doorframe is at the projected position on ground, rising gradually in the ground tilted, also rises, until the upper end of roller starts to contact deceleration blade along with the rising gradually of the position of roller shaft in roller axis hole in the position of roller in roller breach.Because roller is by deceleration blade upwards jack-up, deceleration blade is tightened in roller upper end by the elastomeric material of deceleration blade, now deceleration blade starts pair roller generation frictional force, frictional force simultaneously between ground and roller is also increasing, this is increasing close to fastening position along with timber for upper and lower two bursts of frictional force, produces increasing resistance to timber body.As shown in Figure 4, when timber to arrive before fastening position in a flash, namely be about to clash into doorframe before in a flash, roller has been issued to peak in the support on ground, above roller, the frictional force of deceleration blade and the frictional force of ground pair roller all reach maximum value, and two bursts of power combines and produces maximum resistance to the displacement of timber body, has cut down the kinetic energy of timber body, avoid the shock of body to doorframe of timber, avoid generation impact noise.
A kind of roller type noise abatement timber of the present utility model, can be applied on single fan timber, also can be applied on biparting timber.
