Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is made concrete further instruction.A kind of door lock handle of band bidirectional buffering function, it includes door face board 1 and door handle 2, door handle 2 is by can be on left-right swing type hinged installation door face board 1 at hand 3, being provided with reduction torsion spring 12 at hand, it is characterized in that: described being provided with shift fork 4 at hand 3, can swing by shift fork 4 when rotating at hand 3, described shift fork 4 is also associated with Bidirectional buffering, cushioning effect when shift fork 4 is swung can be played.
Described bidirectional buffer is the first buffer 5 and the second buffer 6 being symmetrically mounted on shift fork 4 both sides, and two buffers are hinged with door face board 1 and shift fork 4 respectively by link gear.
Described link gear includes the hinged seat 7 being arranged between buffer and door face board 1, and the driver blade 8 be located between buffer and shift fork 4 and articulated jib 9.
Described driver blade 8 is in triangular shape, and driver blade 8 is provided with three pin joints, hinged with door face board 1, articulated jib 9 and buffer respectively.
Described door face board 1 back is provided with fixed plate 10, and described hinged seat 7 and driver blade 8 are arranged in this fixed plate 10.
Being equipped with locking hole 11 on described door face board 1, locking hole 11 offside is distributed in Bidirectional buffering both sides, can install locking screw and limit the rotational travel of shift fork in locking hole 11.
The first described buffer 5 and the second buffer 6 are hydraulic buffer cylinder.
Operation principle: in this case, is provided with the first buffer and the second buffer in shift fork lateral symmetry, and two buffers are hinged with shift fork and door face board respectively.As shown in Figure 3,4, when door handle turns right, fork 4 makes the second buffer produce pulling action by left side linkage mechanism, make the first buffer rotate around hinged seat 7 by left side linkage mechanism simultaneously, the pulling action that now the second buffer produces, but the first buffer is wobbling action does not produce damping so that when user opens the door, feel is smooth and easy.When user unclamps door handle, second buffer loses external force and no longer produces pulling action, when promoting shift fork 4 to rotate reset under the effect of reduction torsion spring 12, fork 4 makes the second buffer produce back compressed action by left side linkage mechanism, now the second buffer produces damping action, making door handle slowly be reset to parastate by through transport mechanism, now the first buffer resets around hinged seat 7 revolution and does not produce damping.Due to the first buffer and the transduction of the second buffer, can make door handle during the closedown that automatically resets, related rotation part, by buffer damping, while promoting use feel, reduces noise during work so that it is quiet work smoothly.
As shown in Figure 5,6, door handle, shift fork and buffer unit working state figure when it turns left for door handle, operation acts process when it turns right with door handle is contrary, refer to above, and in this not go into detail.Wherein it should be understood that after door handle in this case opens, dependence is that buffer produces damping action when compression, does not produce the principle of damping, make the effect reaching steadily to buffer in door handle reseting procedure in stretching or rotation process.Thus avoid producing reset components clash into the drawbacks such as the noise that causes at the reset powerful torsion that caused of torsion spring, fundamentally it is effectively improved lockset service life and uses texture.
Further: compared with the door face board technology of tradition one-way buffer, this case is provided with Bidirectional buffering, can make no matter door handle turns left or turn right, can realize pooling feature, therefore this panel can be suitable for the use of L.H.flapped door and R.H.flapped door simultaneously.Wherein, when user needs unidirectional enabling, it is only necessary to locking screw can be installed in corresponding locking hole 11 and limit the rotational travel of shift fork.And user has only to a drawback lock, and door outer handle simply maintains static when playing role in decoration, and can install locking screw in two locking holes simultaneously.Therefore compared with conventional art, the Door lock casing in this case has only to arrange a model, just can use by general all doors the most on the market, it is possible to reduce product type, while convenient production, is also convenient for storage transport and sells.Avoid user in conventional art to need to distinguish model to avoid buying the drawback of shift number, therefore use can be widely popularized.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.
