detailed description

The invention will be further described in detail below with reference to the accompanying drawings. A door lock handle with a two-way buffer function, comprising a door panel 1 and a door handle 2, the door handle 2 being hingedly mounted on the door panel 1 by a left and right swinging handle head 3, wherein the handle head is provided with a reset torsion spring 12, The utility model is characterized in that: the shifting fork 4 is mounted on the handle head 3, and the shifting fork 4 can be driven to swing when the handle head 3 rotates, and the two-way buffering device is also connected to the shifting fork 4, which can be used when the shifting fork 4 is swung left and right. Buffering effect.

The two-way buffer is a first buffer 5 and a second buffer 6 symmetrically mounted on both sides of the shift fork 4, and the two buffers are respectively hinged to the door panel 1 and the shift fork 4 by a linkage mechanism.

The linkage mechanism includes a hinge seat 7 disposed between the buffer and the door panel 1, and a transmission piece 8 and an articulated arm 9 disposed between the buffer and the fork 4.

The driving piece 8 has a triangular shape, and the driving piece 8 is provided with three hinge points which are respectively hinged with the door panel 1, the hinge arm 9 and the buffer.

A fixing plate 10 is disposed on the back of the door panel 1, and the hinge seat 7 and the driving piece 8 are mounted on the fixing plate 10.

The door panel 1 is provided with a locking hole 11 . The opposite side of the locking hole 11 is distributed on two sides of the two-way buffering device. The locking screw 11 can be installed with a locking screw to limit the rotation stroke of the fork.

The first buffer 5 and the second buffer 6 are hydraulic buffer cylinders.

Working principle: In the present case, a first buffer and a second buffer are symmetrically arranged on both sides of the fork, and the two buffers are respectively hinged with the fork and the door panel. As shown in Figures 3 and 4, when the door handle is turned to the right, the fork 4, the second buffer is caused to stretch by the right linkage mechanism, and the first buffer is rotated around the hinge seat 7 by the left linkage mechanism, and the second buffer generates a stretching action, but the first buffer Only the swinging motion does not generate damping, which makes the user feel smooth when opening the door. When the user releases the door handle, the second buffer loses the external force and no longer generates the stretching action. When the shift fork 4 is rotated and reset by the reset torsion spring 12, the fork 4 passes the right linkage mechanism to make the second buffer. The compression action is generated back. At this time, the second buffer generates a damping effect, and the door handle is slowly reset to the parallel state by the interlocking mechanism. At this time, the first buffer is pivotally reset around the hinge seat 7 without generating damping. Due to the switching action of the first buffer and the second buffer, the door handle can be buffer-damped during the automatic resetting and closing process, and the noise during operation is reduced and the noise is quiet and smooth while improving the feeling of use. work.

As shown in FIG. 5 and FIG. 6 , it is a working state diagram of the door handle, the fork and the buffer device when the door handle is rotated to the left, which is opposite to the working operation when the door handle is rotated to the right, please refer to the foregoing, here. I will not go into details. It should be noted that the door handle in this case is opened, relying on the damping effect of the damper during compression, and the principle of no damping during the stretching or rotation process, so as to achieve a smooth buffering effect during the door handle reset process. . Therefore, the disadvantages such as the noise caused by the impact of the resetting member caused by the strong torsion caused by the torsion spring reset are avoided, and the service life and the texture of the lock are fundamentally effectively improved.

Further: Compared with the traditional one-way buffered door panel technology, the two-way buffer device is provided in the present case, so that the door handle can be buffered regardless of whether it is rotated to the left or to the right, so the panel can be simultaneously adapted. Use of left and right open doors. Wherein, when the user needs to open the door in one direction, only the locking screw can be installed in the corresponding locking hole 11 to limit the rotation stroke of the fork. The user only needs to unlock the door, and when the outer door handle is only fixed and decorated, the locking screw can be installed in both locking holes at the same time. Therefore, compared with the traditional technology, the door lock panel in this case only needs to be provided with one model, which can be used for all the doors currently on the market, and can reduce the product model, and is convenient for production. It is also convenient for warehousing, transportation and sales. Avoid the drawbacks of traditional technology in which users need to distinguish models to avoid buying the wrong models, so they can be widely used.

The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited by the foregoing embodiments, and that the present invention is only described in the foregoing description and the description of the present invention, without departing from the spirit and scope of the invention. Various changes and modifications are intended to be included within the scope of the invention as claimed.
