Description
Technical field
The present invention relates to a kind of lockset, and in particular to a kind of handle structure.
Background technology
The locksets such as double fast lock, automatic lock in the market are easy to use, handle are often provided with indoors, under
Pressure handle achieves that unlocking, and thief or criminal are often utilized this feature, destroy opal, stretched into using special instrument
The hand illegal unlock held is pushed in the hole of opal, causes property loss.
CN204457090U discloses the lockset that a kind of anti-opal is unlocked, including handle, handle rotating shaft, panel, and handle can
Rotatably it is located at along axis on panel, handle is provided with axis hole, handle rotating shaft can be rotatably located in axis hole along axis, in addition to by
Groove is provided with part and spring, handle, the boss with matching grooves is axially arranged with by part, the side with handle rotating shaft is additionally provided with by part
Hole matching and stretch into the protruding shaft that can be slided in square hole along axis, spring housing is outside protruding shaft, after external force is pressed into by part, should press part
On boss and the engagement inside handle, matched by the protruding shaft on part with the square hole of handle rotating shaft, push handle, handle is made
Rotate about the axis, by part concomitant rotation, so as to drive handle rotating shaft to rotate about the axis, drive lock body to complete to unlock.When external force solution
After removing, by part under the reset response of spring, slid axially by part with handle rotating shaft, inside the positioning boss and handle on part
Groove disengage, handle rotating shaft and handle can now push handle with 360 ° of relative idle running, and handle rotating shaft is relative with handle to dally
It can not unlock.
In above-mentioned patent document, due to be transported vertically in square hole by the protruding shaft on part in the case where being acted on by part by external force
A dynamic segment distance, accordingly, the square hole of handle rotating shaft needs to leave the gap of protruding shaft movement travel distance, causes square steel insertion to be held
Depth in hand rotating shaft square hole is smaller, while in order to coordinate the installation of square steel to cause the length of handle rotating shaft to be higher than the bottom of panel
Portion, when the handle is in the case of thickness gate is less, handle rotating shaft causes panel not install with lock body interference；Square steel is inserted
The depth entered in handle rotating shaft square hole is smaller, poor to the thick square steel length applicability of different doors；By on part simultaneously provided with boss
And protruding shaft, make by the complicated of part, be difficult manufacture.
The content of the invention
Therefore, the technical problem to be solved in the present invention be to overcome it is of the prior art when the handle be arranged on thickness gate compared with
In the case of small, the interference of handle rotating shaft and lock body causes the defect that panel can not be installed, thus provide one kind be adapted for mount on compared with
Handle structure in wicket thickness.
