Detailed Description

For the purpose of enhancing the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.

As shown in fig. 1 to 6, a silent door stopper comprises a limiting rail 1 and a buffer 2; the limiting track 1 is arranged on the door pocket 3; the buffer 2 is arranged on the door panel 4; the limiting track 1 is provided with a track 11; the buffer 2 comprises a rotary damper 21, a rack 22 and an elastic knob; the rack 22 is meshed with a gear on the rotary damper 21; one end of the rack 22 close to the limiting track 1 is provided with a shifting column 221; the poking column 221 is inserted into the track 11; the spring knob abuts against the end of the rack 22 remote from the limit track 1.

On the basis of the above, the track 11 includes an arc segment and a straight segment.

On the basis, an inner sleeve 12 is arranged in the track 11; the poking column 221 is inserted in the inner sleeve 12.

On the basis, the elastic knob comprises a fixed seat 23, a compression block 24 and a knob 25; the knob 25 is pivoted on the fixed seat 23; a positioning through hole along the moving direction of the rack 22 is formed in the fixed seat 23; the compression block 24 is provided with a positioning pin 241; the positioning pin 241 is inserted into the positioning through hole; the positioning pin 241 is sleeved with a spring 242; the upper end of the knob 25 is propped against the rack 22, and the lower end is propped against the compression block 24.

On the basis, the compression block 24 is C-shaped and comprises two short plates and a long plate; the two short plates are perpendicular to the long plate; the positioning pin 241 is fixed on one of the short plates; a short plate remote from the positioning pin 241 is in contact with the lower end of the knob 25.

In practical use, the limiting track 1 is mounted on the door pocket 3 through screws or buckles and other fixing modes, the buffer 2 is mounted on the door panel 4, and finally the shifting column 221 is inserted into the inner sleeve 12.

In order to facilitate the installation of the shifting column 221, a threaded hole can be formed in the rack 22, a thread is tapped on the shifting column 221, after the limiting track 1 and the buffer 2 are installed, the rack 22 is pulled out, the threaded hole is aligned with the inner sleeve 12, and then the shifting column 221 is locked into the threaded hole and extends into the inner sleeve 12 to complete the installation.

In the closed state, as shown in fig. 5 and 6, the rack 22 is completely retracted in the damper 2, and at this time, the rack 22 abuts against the upper end of the knob 25 in the direction away from the column 221, so that the lower end of the knob 25 abuts against the compression block 24 in the direction approaching the column 221, and the compression block 24 compresses the spring 242 in the direction approaching the column 221.

When the door is opened, the door panel 4 rotates around the hinge, and the door panel 4 drives the shifting column 221 to move along the track 11 through the rack 22; when the shifting column 221 moves to the tail end of the track 11, the shifting column is clamped, if the door panel 4 is opened continuously, the rack 22 is pulled out of the buffer 2, the rack 22 drives the gear of the rotary damper 21 to rotate when moving, the rotary damper 21 generates resistance to reduce the speed of the door panel 4, the door panel 4 is prevented from impacting a wall, and the effect of mute braking is achieved; when door plant 4 opened the maximum position, when rack 22 was all pulled out, rack 22 released the upper end of knob 25, compression block 24 was released to the lower extreme of knob 25, spring 242 released and promoted compression block 24 towards keeping away from group post 221 direction, compression block 24 pulled back the lower extreme of knob 25 towards keeping away from the direction of dialling post 221 and keep, make the upper end of knob 25 support rack 22 towards the direction that is close to group post 221, thereby will dial post 221 card at the end of track 11, prevent that door plant 4 from removing, play the effect of door-inhale.

The mute door stopper is hidden in the door pocket 3 and the door panel 4, and the damping speed reduction brake is occasionally opened to the door, can effectively weaken the noise abatement, and the mute door stopper adopts couple formula location, adds spring assistance-localization real-time, can avoid the phenomenon of kick-backing, has also avoided accident collision between carelessness. In actual use, the length of the rack 22 can be adjusted according to requirements, so that the maximum opening angle of the door panel 4 is changed, and the maximum opening angle of the door panel 4 in the embodiment is 110 degrees; the rotary damper 21 in the damper 2 may be provided in plural, and two rotary dampers 21 are provided in the present embodiment.

The above embodiments should not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent transformations fall within the protection scope of the present invention.
