Description
The utility model relates to a kind of alumium alloy door and window center lock, belongs to building machinery equipment field.
Existing alumium alloy door and window center lock, mainly be to be set with the locking tool in the side of a window sash frame, the locking tool is provided with the hook tool, this hook tool is hinged on the locking tool pivotally, another window sash frame side correspondence is provided with lock hook, mat can rotating hook tool and the overlap joint of lock hook make the locking of two window sash frame, this center lock is manipulated very inconvenient owing to need grasp small-sized hook tool and promote the revolution of hook tool; Chinese patent ZL94214935.1 (notification number CN2206826Y) and ZL96205278.7 (notification number CN2251021Y) disclose a kind of aluminium alloy door sash lock, the sash lock of these two kinds of structures all can pin two fan windows by a lock, but the sash lock of this structure is owing to closing the sash lock window or windowing and unblank all to need be finished by two actions that independently separate, when promptly windowing, need first pressing key and unblank, laterally push hard the fan of windowing then, when closing window, earlier with the hand push sash and be close to, pressing lock lock window then, manipulate loaded down with trivial details like this, inconvenience the phenomenon that latches occurs forgetting behind the window of pass easily, reliability is poor.At above-mentioned situation, Chinese patent ZL98231776.X (notification number CN2345651Y) discloses a kind of safe automatic window catch, this safe automatic window catch only need be operated unlatching once when windowing, need not operate when closing window, and locked when shut when closing window, but the sash lock complex structure of this structure, the production and assembly inconvenience, efficient is low, the cost of production height, and because its operating range of stirring device is limited, cause the distance of dead bolt activity limited, the length that makes it stretch into the snap close lockhole is shorter, and before generally having between two aluminum windows, the gap of back beat, therefore, when promoting sash from the outside, have dead bolt release lock padlock hole and the possibility of unblanking, thereby influence the safe antitheft of aluminum window with external force.
The purpose of this utility model provides and a kind ofly can shut automatically when closing window, and alumium alloy door and window simple in structure, easy to assembly, quick, cheap, that safe antitheft is higher are locked with automatic center.
The utility model comprises lock body, locking bolt, resetting means, snap close, it is characterized in that lock body is provided with the cavity of hollow, and have the hole that can supply the locking bolt leading portion to stretch out on this cavity header board, locking bolt is slidably disposed in the cavity of lock body, its upper top is provided with the handle that can spur locking bolt, resetting means is arranged on behind locking bolt and the cavity between the plate, and the snap close correspondence is installed on another window sash frame, and it is provided with the lockhole that can pass locking bolt.
The utility model since locking bolt by resetting means can before, after be slidingly arranged in the lock body cavity, thereby in two fan window drawings, locking bolt realizes that in colliding the lockhole that can enter snap close automatically it shuts, can be and when windowing, only need pull back two simple motions of handle simultaneously so that locking bolt breaks away from snap close, therefore have easy for operation simple, quick advantage reliably, particularly structure is simpler, volume is smaller and more exquisite, easy to assembly quick, the production efficiency height, cost of production is low, and because the activity space of locking bolt handle is big, the length of dead bolt can be longer than the dead bolt of general sash lock, make the fastening of dead bolt and snap close more reliable, firmly, effectively improve its safe antitheft, practical, can be widely used in the alumium alloy door and window of all size.
Describe basic structure of the present utility model and operating principle in detail below in conjunction with accompanying drawing:
Fig. 1 is that the utility model is installed in the structural representation on the window frame;
Fig. 2 is a vertical profile structural representation of the present utility model;
Fig. 3 is a cross-sectional structural representation of the present utility model;
As shown in Figure 1-Figure 3, the utility model comprises lock body 1, locking bolt 3, resetting means 4, snap close 2, wherein lock body 1 is provided with the cavity of hollow, and have the hole that can supply locking bolt 3 leading portions to stretch out on this cavity header board, locking bolt 3 is slidably disposed in the cavity of lock body 1, and its upper top is provided with the handle 32 that can spur locking bolt 3, and resetting means 4 is arranged on behind locking bolt and the cavity between the plate 11, snap close 2 correspondences are installed on another window sash frame, and it is provided with the lockhole that can pass locking bolt 3.For make locking bolt 3 in lock body 1 cavity, slide steadily, reliable, above-mentioned locking bolt 3 leading portions are dead bolt 31, its back segment is for covering the cover plate of putting on lock body 1 cavity 33, above-mentioned handle 32 semicirculars in shape, for making handle 32 pullings convenient, reliable, the surface of handle 32 is provided with some raised lines, and be wholely set at this cover plate 33 front ends, and cover plate 33 is higher than dead bolt 31 and connects as one with dead bolt 31 steppedly.The wing plate 12 that stretch in being provided with both sides in the cavity of lock body 1, this wing plate 12 are formed with well floor and side plate can supply the guide groove of the dead bolt 31 forward and backward slips of locking bolt 3, and its end face forms the guide groove face that can slide for the cover plate 33 of locking bolt 3.The dead bolt of above-mentioned locking bolt is arranged in the guide groove of lock body cavity and the hole on the extended lock body header board; The cover plate of above-mentioned locking bolt be arranged on the guide groove face of lock body cavity and the handle overhead of locking bolt at the top of lock body header board frame.Back plate 11 is installed in the rear portion of lock body 1 cavity removably by bearing pin 13, and the end face of the end face of this back plate 11 and above-mentioned wing plate 12 is positioned on the same horizontal plane.Slide with the whole process that makes things convenient for locking bolt 3 cover plates 33, assurance dead bolt 31 can be made longer, thereby further strengthens sealed security reliability.For making things convenient for the installation of resetting means 4, it is simple, reliable that resetting means 4 is installed, and above-mentioned back-moving spring 4 is two stage clips, and these two stage clips are arranged in parallel in lock body 1 cavity at locking bolt 3 and afterwards between the plate 11.Dead bolt 31 rear portions of above-mentioned locking bolt 3 have two can ccontaining stage clip cylindrical hole, wherein an end of stage clip is nested with in the cylindrical hole at dead bolt 31 rear portions, its other end holds out against the back plate 11 of lock body 1 cavity.When closing window, realize automatically shutting for further guaranteeing the utility model, and make sealed more firm, reliable, the clinohedral of arc transition is made in the lower surface of the dead bolt 31 of above-mentioned locking bolt 3, the plane body that can flush with the lockhole of snap close 2 is made in its upper surface, the curving body that can collide and connect with the clinohedral of dead bolt 31 is made in the outer end of above-mentioned snap close 2, and its lockhole is a square opening.
