Abstract

The utility model relates to a blind automatic crescent lock which is used for plastic-steel push-pull windows and aluminium alloy push-pull windows. The utility model solves the technical problem that an ordinary manual crescent lock can not automatically lock the window when the window is be closed. The main structure of the blind automatic crescent lock is composed of main parts such as a shell body [1] of a lock seat, a crescent bolt [2] with a gap [9], a control rod [4] with a clamping key [10], a lock catch [6], a poking machine [7], a torsional spring [8], etc. When the window is closed, the poking machine [7] pushes off the control rod [4] which clamps the crescent pin [1]. Under the action of the torsional spring [8], the crescent pin enters the lock catch [6] to be locked with the lock catch [6] after the crescent pin rotates at an angle of 180 DEG. When the window is to be opened, the handle [5] is screwed and rotated reversely at an angle of 180 DEG so that the crescent bolt disengages from the lock catch. The blind automatic crescent lock of the utility model has the advantage of simple, easy, convenient and reliable operation.

Description

Stealthy Lock for crescent window automatically

The utility model relates to a kind of Lock for crescent window, a kind of can be automatically with up and down or the plastic-steel of left and right sides push-and-pull, the aluminum alloy push-pull sash lock stealthy crescent moon automatic window catch of living.

The Lock for crescent window domestic at present and American market is sold can not be lived two fan sash locks when closing window automatically, and need to turn handle and pin window with hand, the troublesome poeration effort, very inconvenient.

When being exactly a kind of pass window that designs in order to overcome above-mentioned shortcoming, the purpose of this utility model can automatically two fan windows be pinned, the stealthy Lock for crescent window automatically that switch window operation is easy and convenient especially more is applicable to the U.S.'s stealthy Lock for crescent window automatically of using of the plastic-steel sliding window of push-and-pull up and down.

The technical solution of the utility model: crescent moon bolt [2] and control lever [4] are installed in lock housing [1], semicircle handle [5], torsion spring parts such as [8], the hinged handle [5] that is installed with in the axis hole [17] of lock housing [1], handle [5] is gone up on the flat axle [11] that is provided with and is being fixedly mounted crescent moon bolt [2], axle [11] lower end part of handle [5] has gap [15], torsion spring [8] the one end that is sleeved on axle [11] lower end just is stuck in the gap [15], lock housing [1] is gone up the axle [12] that is provided with and is gone up hinged control lever [4] and the back-moving spring [3] of being installed with, card key [10] is set on the control lever [4], the outer rim [23] of crescent moon bolt [2] is provided with can be blocked the gap [9] that key [10] blocks, lock [1] is gone up to reach and also is provided with the positive stop [20] that restriction crescent moon bolt can only rotate 180 ° on the crescent moon bolt [2], [22], an end of control lever [4] stretches to snap close [6] by the opening [13] on the lock housing [1]; Interior hinged being installed with of axle bed [16] that is installed in the left side of (being on the fixing top window of U.S.'s dwelling house) snap close [6] on another fan window can be stirred group machine [7] and the back-moving spring thereof that have inclined-plane [14] that control lever [4] rotates an angle; It closes the window self-locking property and is achieved in that with U.S.'s sash window be example, the movable window that pulling is downwards being opened, after the inclined-plane [14] of group machine [7] on the snap close of installing on the overhanging termination of control lever [4] of the stealthy crescent lock of control mounted thereto and the top fixedly window [6] contacts, control lever [4] is pushed to an angle by inclined-plane [14], card key [10] on the control lever [4] is just thrown off with the gap [9] on the crescent moon bolt [2], drives that 180 ° of crescent moon bolt [2] one-tenth that are hidden in down in the lock housing [1] spin out and pins (horizontally sliding window also is like this) with snap close [6] voluntarily at the potential energy of torsion spring [8]; Turning 180 ° of handle [5] crescent moon bolt [2] counter-rotatings when windowing throws off with snap close and just can open the window.

Owing to adopt technique scheme, the operation of closing window just can be easily with two fan slide window locks together.

Below in conjunction with accompanying drawing the utility model is advanced an explanation.
