Description

A kind of door lock lock out damping unit

Technical field

The utility model relates to a kind of door lock buffer, relates to a kind of door lock specifically and lock out damping unit.

Background technology

Automatic door lock is when automatic blocking, usually discharge elastic energy as power by being arranged on the interior compression spring of lock housing, drive dead bolt by transmission mechanism and lock out, because the elastic energy of spring discharges soon, dead bolt lock out also relatively rapidly, and the Shi Douhui that at every turn locks a door sends the sharp-pointed impact sound of dead bolt knocking door case.

In order to address this problem, Chinese patent literature CN102606711A discloses a kind of unidirectional rotary adjustable cushion of semi-automatic translation door, it comprises housing, end cap, gear, main damping wheel, secondary damping wheel and rotating shaft, described end cap is fixed the cavity that forms a sealing with lock screw and housing, the arranged outside of described end cap has bearing, its inboard is provided with bearing seal, the bearing on the described end cap is passed in described rotating shaft, main damping wheel and secondary damping wheel are arranged in the cavity and are set on respectively in the described rotating shaft, and be meshing with each other by the end face meshing gear, be full of the damping grease in the described cavity; The bearing in the outside of described end cap is provided with bearing cover, and described geared sleeve is located in the rotating shaft and is chimeric with described bearing cover.The life-span of adopting the prior art can not only improve snubber; Simplified the Installation and Debugging process; Also make the work of snubber more stable.

But the unidirectional rotary adjustable cushion of the described a kind of semi-automatic translation door of above-mentioned patent documentation has the following disadvantages: 1) this adjustable cushion is a kind of special snubber, when it is applied in the door latch structure, need in lock housing, to arrange specially this adjustable cushion, thereby take certain space, increase the lock housing volume, be unfavorable for the installation of lock housing on door; 2) this adjustable cushion complex structure, cost of production are higher, when it is applied in the door latch structure, have increased the cost of door lock.

The utility model content

For this reason, technical problem to be solved in the utility model is that a kind of unidirectional rotary adjustable cushion of semi-automatic translation door is a kind of special snubber in the prior art, when it is applied in the door lock, it is big to take up room, increased the problem of the volume of lock housing, provide a kind of take up room little, can not increase the lock housing volume, be convenient to the door lock that lock housing installs and lock out damping unit.

Further provide a kind of door lock simple in structure, that cost of production is low to lock out damping unit.

For solving the problems of the technologies described above, a kind of door lock of the present utility model lock out damping unit, it is characterized in that: comprise
