Abstract

The utility model discloses a push-button semi-automatic lock for sliding doors or windows, which is provided with a rocking-arm type movable lock hook and a corresponding button assembly. The movable lock hook is driven to rotate horizontally through the up and down movement of an inclined plane of the button assembly to be disconnected with a fixed lock hook; when a door or a window is opened or closed, the movable lock hook overcomes restoring spring force to cause a rotating arm to rotate; after restoring position, the rotating arm automatically resets and are fastened by a restoring spring to avoid of unnecessary loss, when the door or the window is closed but not fastened. The utility model has the advantages of compact structure, convenient installation and convenient adjustment.

Description

The semi-automatic lock for sliding door and window of push button

The utility model relates to a kind of door and window lock, relates in particular to a kind of lock for sliding door and window.

At present, the lock for sliding door and window on the market mostly is hand, also need lift the manual fastening of latch hook after door and window is closed, and pushes latch hook during unlatching again, uses more complicated; And latch hook is installed, adjusts loaded down with trivial details, and latch hook gets loose easily, and security reliability is poor.

The purpose of this utility model is to overcome the deficiencies in the prior art, but automatic locking after a kind of the closing the doors and windows is provided, and the latch hook novel lock for sliding door and window that is difficult for getting loose.

The purpose of this utility model is achieved in that the push-jump arm of design one cover sloped roof, and the spring automatic reset mechanism is used for the door and window automatic locking, presses unlatching.Its concrete structure is: the turret terminal that has the button assembly on inclined-plane is inserted in panel, and the other end is inserted in pressing plate; Bolster one end is fixed in panel, and the other end is fixed in pressing plate, and movable latch hook (pivoted arm) end is sleeved on the bolster, and uses the Lower shaft sleeve axial location; Back-moving spring one end is fixed in pressing plate, and the other end is fixed in movable latch hook middle part; Between the top of button assembly and pressing plate, be provided with spring.

Can there be a projection at movable latch hook described in the utility model and the button assembly place of connecing.

The utility model is provided with pivoted arm activity latch hook, and the drive activity that the moves up and down latch hook on the inclined-plane by button assembly horizontally rotates, and makes it break away from fixedly latch hook, door and window; When closing the doors and windows, movable latch hook overcomes back-moving spring power makes pivoted arm rotate, and the back back-moving spring that puts in place is with the pivoted arm fastening that automatically resets.Forget fastening after avoiding door and window to close and produce unnecessary loss.Simultaneously, because the utility model compact conformation can install and fix this device as long as bore a corresponding circle hole on position to be installed, install easy to adjust.Thereby save the trouble that to draw square hole just can load onto when the door and window lock is installed in the background technology.

Reaching embodiment in conjunction with the accompanying drawings is further described the utility model:

Accompanying drawing 1, the utility model structural representation;

Accompanying drawing 2, the utility model A-A sectional view;

Accompanying drawing 3, the utility model tightening state schematic diagram;

Shown in accompanying drawing 1, accompanying drawing 2, the utility model is made up of panel (1), button assembly (2), pressing plate (4), bolster (5), movable latch hook members such as (7).The turret terminal (21) that has the button assembly (2) on inclined-plane is inserted in panel (1), and the other end is inserted in pressing plate (4); Bolster (5) one ends are fixed in panel (1), and the other end is fixed in pressing plate (4), and pivoted arm activity latch hook (7) one ends are sleeved on the bolster (5), and use, Lower shaft sleeve (6), (8) axial location; Back-moving spring (9) one ends are fixed in pressing plate (4), and the other end is fixed in movable latch hook (7) middle part; Between the top of button assembly (2) and pressing plate (4), be provided with spring (3).Movable latch hook (7) is gone up and there is a projection (71) button assembly (2) contact position.

In the present embodiment, button assembly (2) middle part is a cone, and last planar diameter is 8 millimeters, and the lower plane diameter is 13 millimeters, and height is 8 millimeters.

Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, during use, fixedly latch hook (10) is installed on the doorframe and window frame.Lock brill one corresponding circle hole on the position to be installed at door and window, the semi-automatic lock for sliding door and window of the utility model push button is installed and fixed, can use.When button assembly (2) advances about 5 millimeters inwards, the gradient that button assembly (2) is gone up cone will produce 1.56 millimeters (L/5=[(13-8) ÷ 2 of vertical displacement L ≈]/8), this displacement L promotion activity latch hook (7) rotates, on bill, produce 3L=3 * 1.56=4.86 millimeter arc length, make movable latch hook (7) break away from fixedly latch hook (10).Behind the door and window, hand leaves turret terminal (21), and spring (3) resets button assembly (2) and holds out against on panel (1).When door and window is closed, when the front end of movable latch hook (7) touches fixedly latch hook (10), movable latch hook (7) will overcome the pulling force of back-moving spring (9) along the inclined-plane, progressively open, after the inclined-plane leaves fixedly latch hook (10), back-moving spring (9) is about to movable latch hook (7) and pulls on, and fastening is on fixing latch hook.

Claims
