Abstract

The utility model relates to an automatic lock for a crescent window, which is used for an aluminium alloy sliding window, and mainly solves the technical problem that a window can not be automatically locked when the window is closed by a crescent lock. The utility model is mainly composed of a crescent bolt (1), a lock seat (9), a drive rod (2), a control key (4), a lock catch (5), a touch plate (7), a spiral cylindrical spring (3), etc. When the window is closed, the control key (4) clamping the crescent bolt (1) is pushed off by the touch plate (7), the drive rod (2) pushes the crescent bolt (1) to rotate 90DEG under the action of the cylindrical spring (3), the lock catch (5) is locked, when the window is opened, the drive rod (2) is pressed to drive the crescent bolt to reversely rotated 90DEG, the crescent bolt is disengaged from the lock catch (5). The automatic crescent lock of the utility model has the advantages of simple and convenient operation, safety and reliability.

Description

Automatic Lock for crescent window

The utility model relates to a kind of Lock for crescent window, a kind of automatic Lock for crescent window that can pin sliding sash automatically.

Commercially available Lock for crescent window can not be lived two fan sash locks when closing window automatically at present, need manually, and the troublesome poeration effort, very inconvenient.

The purpose of this utility model is exactly can automatically two fan windows be pinned the automatic Lock for crescent window that fenestration procedure is easy and convenient during for a kind of pass window that overcomes that above-mentioned shortcoming designs.

The technical solution of the utility model: becoming to be rotatably assorted to be installed with in lock [9] is provided with a flat mandrel [[10] on crescent moon bolt [1], the crescent moon bolt [1], [10] go up fixed installation one sheave [6], hinged operating key [4] and the back-moving spring [8] thereof of being installed with in the lock [9] with two grooves; Spiral cylinder compression spring [3] is enclosed within on the drive rod [2], and its other end leans against on the lock [9]; Drive rod [2] is provided with straight pin [11] and is slidingly fitted in the chute [12] that crescent moon bolt [1] bottom surface is provided with, be installed in the snap close [5] on another fan window, the hinged touch panel [7] that has inclined-plane [16] that is installed with in its underpart, the operating key [4] that blocks the last sheave [6] of crescent moon bolt [1] of hinged installation was pushed a corner open and is left sheave in inclined-plane [16] when closing window on the touch panel [7] was understood lock [9], crescent moon bolt [1] is half-twist under drive rod [2] and spring action, enter in the latch hook of snap close [5] sash lock is lived, push drive rod [2], 90 ° of crescent moon bolt [1] counter-rotatings and latch hook break away from.

Because once pushing away two fan sash locks firmly, one withdraws from latch hook on the snap close by drive rod crescent moon bolt, operates easy and convenient when adopting technique scheme just can realize closing window.

Below in conjunction with accompanying drawing the utility model is further specified.

Below the utility model example is further described architectural feature and operating principle.

Fig. 1,2, in 3, lock [9] is gone up the hinged crescent moon bolt [1] that is installed with, crescent moon bolt [1] lower end is fixedly mounting the sheave [6] that has 2 grooves, the shoulder [19] of the controlled key of groove [4] of sheave [6] blocks motionless, operating key [4] is hingedly mounted on the lock [9] with straight pin [17], and the spring that is reset [8] compresses and leans against on the sheave [6], the last suit of drive rod [2] that is slidingly mounted on the lock [9] spiral cylinder compression spring [3], [3] the other end leans against on the wall of lock, the last plane that drives the drive rod [2] of crescent moon bolt [1] rotation is provided with straight pin [11], [11] be slidingly mounted in 45 ° of chutes [12] at crescent moon bolt [1] back side, fan at other snap close [5] is installed on the window, the composite member of touch panel [7], snap close [5] upper end has latch hook, with hinged touch panel [7] and the back-moving spring [24] of being installed with of straight pin [20], touch panel [7] is blocked by straight pin [22] below it.

Fig. 4,5 is the embodiment that drives the 2nd design scheme of crescent moon bolt [1] rotation, on crescent moon bolt [1], fixedly mounting gear [14], the drive rod [2] that on lock [9], is being slidingly installed band tooth bar [15] and is meshing with gear [14], the one end is installed between lock [9] and crescent moon bolt [1] to withstand on the lock [9], the other end withstands on the crescent moon bolt blade, becomes the helical spring [13] of annular.

The automatic crescent lock operation of the utility model is:

Operating key [4], crescent moon bolt [1], the composite member of lock [9] is installed on the fan sliding sash, snap close [5], touch panel [7] composite member is installed on another fan window, when two fan windows are in open mode and need close window, promote the operating key [4] on the fan window lock [9], inclined-plane [16] touching by back of the gap [23] on the snap close [5] and touch panel [7] forces operating key [4] to locate deflection one angle at the gap [18] of lock [9], shoulder [19] just with crescent moon bolt [1] on sheave [6] throw off (at this moment, operating key [4] is under back-moving spring [8] effect, get back to original position from touch panel [7] below), crescent moon bolt [1] is in drive rod [2], spiral cylinder spring [3] effect is half-twist down, and the crescent stile [21] on the crescent moon bolt [1] changes in the latch hook that enters snap close [5] fans the window automatic lockings together with two; When pushing drive rod [2], crescent moon bolt [1] reverses 90 ° under straight pin [11], crescent moon bolt bottom surface chute [12] effect, crescent moon bolt [1] is gone up the latch hook that crescent stile [21] produces snap close [5], just can open the window (the push-jump touch panel of operating key when opeing the window [4] [7] is also by the breach [23] on the snap close [5]).
