Description

Door lock

Technical field

The utility model relates to a kind of lockset, and more particularly, it relates to a kind of door lock of Convenient switch door.

Background technology

At present, the switch gate mode of the door lock on market is generally torsional mode, and this door lock mainly comprises lock body and square core, and described lock body is provided with the Fang Xin perforation that supplier's core passes, and Fang Xin to be bored a hole through lock body by square core.This door lock makes Fang Xin rotate by turning the handle, and coordinates by Fang Xin and square perforation the action driving lock body internal construction, and finally make dead bolt regain in lock body, dead bolt is no longer stuck between door and doorframe, then carrys out switch gate by push-and-pull.The switch gate of this door lock needs rotation and push-and-pull two actions, in hand, hold thing, particularly has a lot of inconvenience during hand-held weight inconvenience switch gate.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is the door lock providing a kind of Convenient switch door.

For achieving the above object, the utility model provides following technical scheme: a kind of door lock, mainly comprise lock body and square core, described side's core periphery comprises several faces, described lock body is provided with the Fang Xin perforation that supplier's core passes, the matching form of Fang Xin and Fang Xin perforation closes, and it is characterized in that: described the axle center around Fang Xin extends spirally, and Fang Xin is slidably arranged in Fang Xin perforation.

By adopt technique scheme, Fang Xin moves vertically, Fang Xin in Fang Xin perforation place through lock body, in Fang Xin perforation place, Fang Xin is in rotary state relative to lock body, and square core rotates relative to lock body and drives lock body internal construction to move, and then dead bolt is stretched out or takes in lock body.By adopting technique scheme, rely on the axially-movable of lock core but not circumferential movement can realize the switch of door lock.

The utility model is set to further: described extends from square core two ends relatively respectively to middle counter-clockwise direction.

By adopting technique scheme, be that dead bolt stretches out state when the intersection of both direction is positioned at Fang Xin perforation place, door lock is in closed condition.When Fang Xin moves to the either direction of axis, the rotation direction that Fang Xin bores a hole relative to Fang Xin is identical, is all to drive door lock internal construction to rotate, in dead bolt income lock body.

The utility model is set to further: described lock body both sides are equipped with spring, core periphery, the described spring housing side of being located at, and is fixedly installed at the spring end of lock body homonymy and square core end.

By adopting technique scheme, arranging spring can after Fang Xin moves, and utilize the elastic force of spring to make Fang Xin get back to original position, namely dead bolt stretches out lock body, and door lock is in closed condition.

The utility model is set to further: described lock body both sides are respectively equipped with front panel and rear board, described front panel and rear board are equipped with door handle, described door handle is all connected by handlebar stem with between front door or Rear Door, and described Fang Xin is fixedly linked with two ends door handle respectively.

By adopting technique scheme, front panel and rear board play fixing and booster action in whole door lock, and Fang Xin is connected with door handle by handlebar stem, realizes moving axially of Fang Xin by sliding door handle.

The utility model is set to further: described handlebar stem is axial for slidably to arrange along handlebar stem on front panel or rear board, and described handlebar stem is circumferential for being fixedly installed along handlebar stem on front panel or rear board.

By adopting technique scheme, when making sliding door handle, can effectively prevent lock core own rotation, in other words, can ensure that lock core effectively drives institute's body internal construction to rotate.

Detailed description of the invention

Referring to figs. 1 through Fig. 2, the utility model door lock embodiment is described further.

As shown in Figure 1 to Figure 2, a kind of door lock, mainly comprise front panel 1, rear board 2 and lock body 3, lock body 3 is arranged between front panel 1 and rear board 2, and lock body 3 comprises dead bolt 9, and front panel 1 and rear board 2 are equipped with door handle 5, door handle 5 is all connected by handlebar stem 6 with between front panel 1 or rear board 2, lock body 3 is also provided with Fang Xin perforation 7, square core 4 is through Fang Xin perforation 7, and two ends are fixedly linked with two door handles 5 respectively.

The primary structure of this door lock is roughly the same with the structure of door lock in prior art, and its key difference is characterised in that, four faces of square core 4 periphery of this door lock are along square core 4 axis to extending spirally, side core 4 each cross section be evenly equal square, and square core 4 Fang Xin perforation 7 in for slidably to arrange.Further, be between handlebar stem 6 and front panel 1 and between handlebar stem 6 and rear board 2 and axially slidably arrange along handlebar stem 6.By sliding door handle 5, the side's of making core 4 moves axially in Fang Xin perforation 7, side core 4 move axially relative to Fang Xin bore a hole 7 be circular-rotation, the spiral-shaped of the side's of moving through core 4 of horizontal direction converts circular motion to, drive the work of lock body 3 internal construction, dead bolt 9 is taken in or stretches out lock body 3.

Between above-mentioned handlebar stem 6 and front panel 1 and between handlebar stem 6 and rear board 2 along handlebar stem 6 axially for slidably to arrange, and between handlebar stem 6 and front panel 1, between handlebar stem 6 and rear board 2 along handlebar stem 6 circumference for being fixedly installed, specifically can be set between front panel 1 with handlebar stem 6 and groove and the fin structure of corresponding axis is all set between rear board 2 and handlebar stem 6, by the Qian He of groove with fin, both ensureing that handlebar stem 6 can slide axially in front panel 1 or rear board 2, can circular-rotation be there is and affect the effect driving lock body 3 internal construction by the side's of avoiding core 4 again.

Above-mentioned side's core 4 is that spiral torsional is curved, if this spiral defence line is entirely same clockwise and arranges, then 6 two actions of sliding door handle only have one can open the door, if the face of square core 4 periphery extends from square core 4 two ends relatively respectively to middle counter-clockwise direction, the spiral angle of each is 90 degree, intersection is in smoothing junction, dead bolt 9 stretch out lock body 3 pin door time, to bore a hole 7 places at Fang Xin in the intersection position of two hands of spiral, square core 4 moves to any one direction and dead bolt 9 all can be made to take in lock body 3.

In order to more time saving and energy saving, after making sliding door handle 5, dead bolt 9 can recover automatically, is equipped with spring 10, core 4 periphery, spring 10 side of being set between lock body 3 and front panel 1 and rear board 2, and spring 10 one end is fixed on corresponding square core 4 one end.

The above makes preferred embodiment of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
