Description
Technical field
The utility model is related to technical field of buildings, more particularly to a kind of sash lock for being easy to open and close.
Background technology
The component of door and window lock mainly includes handle, lock body, installation base plate；But lock body and handle are needed traditional product when mounted
It is installed separately, this is accomplished by setting supporting lock body mounting groove on door and window, each size of the mounting groove, which is met, can hold lock
Body, the size of installation base plate must be met when can be positioned at notch, i.e. installation base plate and mounting groove and coordinating, at least two points or
It is located at the position beyond notch above, so as not to be absorbed in groove；Structure operability overall when mounted is poor, is needed during maintenance
Whole lock body is all torn open, not only increases maintenance cost, and performance is poor, installs trouble；Additionally, due to traditional door
Lock construction stroke is shorter, it is necessary to open the stroke between handle, two sliding blocks of shortening with larger angle, to realize unlocking, again
By spring reset during position, but due to being limited by space between two sash, it is impossible to realize and open handle with less angle
It can just realize that the displacement that larger stroke, i.e. sliding block occur is enough to unlock, overall operating characteristics is poor, and poor reliability makes
With relatively painstakingly.
In order to overcome above mentioned problem, the applicant discloses a kind of lever integrated lock in 2013-02-06（Application number：
201220457731.5 ）, this lock is will to lock the both sides that main body and handle are respectively arranged on installation base plate, by the way that lock main body is contracted
It is small and form one with handle, installation base plate so that lock main body directly can stretch into mounting groove by the notch of mounting groove, therefore
Overcome traditional locks and need to entirely be locked in installation or maintenance and all dismounted, not only increase maintenance cost, traditional locks main body passes through two
Group spring also causes overall heaviness to realize reset and steady operation, and performance is poor, the problems such as installing trouble.
After this lock is arranged on forms, its unlocking direction is consistent with windowing direction, and a problem occurs when in use,
If as lock body can only be affectedly bashful the afterbody in handle, can thus become to be difficult to when in use installed in high position, user is compared
Open lock and either open window, and this lock is realized with the link gear on forms using spring, i.e., will by spring
Lock connection on sliding block and forms in lock body, after being unlocked also with a back-moving spring in the spring and lock body
And realize and reset, after a long time use, the spring in forms is it is possible that spring fatigue, may now be accomplished by handle
Lock could be opened in maximum hunting range edge, so in-convenience in use, it is to be improved.
The content of the invention
In order to overcome above mentioned problem, this is new there is provided a kind of sash lock for being easy to open and close.
To achieve the above object, the technical scheme of this new offer is：
A kind of sash lock for being easy to open and close, including handle and lock body；One end of the handle is rotatably fixed on lock body,
Handle, which is located on lock body, is partly fixedly connected with one-stage gear；Two are additionally provided with the lock body can opposing parallel movement
Rack；Secondary gear is provided between two racks, secondary gear is engaged with one-stage gear and two racks simultaneously.
The bottom of any rack is provided with resetting means.
Described resetting means includes back-moving spring, and the two ends of back-moving spring act against fixed pillar one and any tooth respectively
The inner side of bar.
The bottom of one of them described rack is provided with spring groove, back-moving spring is arranged in spring groove.
The gear ratio of the secondary gear and one-stage gear is more than 1.
The central axis of the one-stage gear and the centerline axis parallel of secondary gear.
The rotation direction of the handle is vertical with the direction opened a window.
Torsion spring and locating part are additionally provided with the junction of the handle and lock body, torsion spring set is on handle, locating part
It is arranged on the movement locus of torsion spring, the set location of locating part is satisfied with：Under without external force state, torsion spring can answer handle
Position.
Above-mentioned technical proposal is beneficial in that：
This is new there is provided a kind of sash lock for being easy to open and close, and realizes in the prior art using the vertical oscillation of handle
The mode that the mode moved with movable slider is changed to the horizontal hunting using handle and moved with carry-over bar, user can directly pass through
Swing handle and open sash lock, if can avoid in the prior art lock body installation site it is too high, user is difficult to hold handle and lead
The situation for being difficult to unlock or opening a window is caused to occur, it is easy to use, and install simple.
It is clearly and completely described below in conjunction with the accompanying drawing technical scheme new to this, it is clear that described implementation
