Abstract
The electrically locking mechanism for door and window is simple structure, simple installation and other advantages. It includes a motor; a first bevel gear fixed to the rotation shaft of the motor; a second bevel gear meshed with the first one and with thread hole in the rotation direction; a locking screw bolt meshed with the thread holes and with one pointed end; and a lock hole with inwards reduced size. Preferably, the locking screw bolt has diameter in the other end smaller than that in the middle part. Furthermore, the electrically locking mechanism includes also one clamping plate fixed to one side of the second bevel gear and provided with notch or thread holes in the size between the diameter of the other end of the screw bolt and the diameter in the middle part.
Description
Technical field
The present invention relates to accessories for windows and doors, particularly a kind of locking mechanism that locks door and window in electronic mode.
Background technology
Fig. 1 is a kind of schematic diagram of electric locking mechanism for door and window, as shown in Figure 1, it mainly comprises tooth bar 11, gear 12 and electric machine assembly 13, wherein, tooth bar 11 is fixed on the sash, and gear 12 is arranged at section bar surface and tooth bar 11 corresponding positions, promptly when sash is in fully or is about to close they can nibble mutually and the position, electric machine assembly 13 is installed in the section bar die cavity and output shaft directly links to each other with gear 12, thereby driven gear 12 rotates.When sash was in approaching closing, electric machine assembly 13 driven gears 12 rotated, and drive tooth bar 11 motions thus, make sash inwardly fix a point to rotate, and close sash at last fully.
But in above-mentioned this electric locking mechanism, tooth bar is directly exposed on the sash under the environment owing to being fixed in, and this not only influences attractive in appearance, thereby and the time grown having some setbacks that the distortion that might cause tooth bar causes that wheel and rack cooperates.In addition, this locking mechanism also has higher requirement to the installation site precision of wheel and rack.
Summary of the invention
The purpose of this invention is to provide a kind of electric locking mechanism for door and window, it has simple in structure and advantages such as convenient is installed.
Above-mentioned purpose of the present invention is passed through following technical proposal:
A kind of electric locking mechanism for door and window comprises:
Motor;
First helical gear, it in rotational direction is fixed in the rotating shaft of described motor;
Second helical gear, itself and described first helical gear mesh and in rotational direction offer threaded through hole;
The locking bar of screw thread is offered on the surface, its by be threadedly connected to described through hole and wherein an end be tip shape;
Near the lockhole, its opening aperture inwardly dwindles gradually.
Reasonablely be, in above-mentioned electric locking mechanism for door and window, the external diameter of the described locking bar other end is less than the external diameter of its stage casing part, further comprise the clamp that is fixed in described second helical gear, one side and offers breach or screw on it, the bore of described breach or the aperture of screw are between the external diameter of the external diameter of the described locking bar other end and its stage casing part.
Reasonablely be, in above-mentioned electric locking mechanism for door and window, further comprise frame, the described motor and second helical gear are mounted thereon.
In electric locking mechanism for door and window of the present invention, adopt locking bar and lockhole to realize location and locking, so compact conformation, easy for installation.
Description of drawings
Fig. 1 shows a kind of schematic diagram of existing electric locking mechanism for door and window.
Fig. 2 is the electric locking mechanism for door and window schematic diagram according to preferred embodiment of the present invention.
Fig. 3 is for to cut open the generalized section of getting according to Fig. 2 cathetus A-A.
The specific embodiment
Below by accompanying drawing preferred embodiment of the present invention is described.
As shown in Figures 2 and 3, preferred embodiment comprises motor 1, first helical gear 2, second helical gear 3, locking bar 4, lockhole 5, frame 6, clamp 7 and lock housing 8, wherein, frame 6 is fixed on the installing plate 9, it mainly is to provide the installation site for parts such as motor 1, first helical gear 2, second helical gear 3, locking bar 4 and clamps 7, lock housing 8 is fixed on the installing plate 9, and its encirclement is installed in parts on the frame 6 to reach purposes such as dustproof, damp proof and anti-external impacts.
Referring to Fig. 2, motor 1 is installed on the frame 6, and its rotating shaft 1a can rotate around axis a-a.First helical gear 2 portion within it in rotational direction offers cavity, and the rotating shaft 1a of motor 1 is fixed in the cavity, like this, when motor 1 rotates, will drive helical gear 2 and rotate together.On the other hand, second helical gear 3 also is installed on the frame 6, its installation site is vertical with first helical gear, 2 rotation directions and can intermesh, and therefore rotates around axis a-a under motor 1 rotating shaft drives when first helical gear 2, and second helical gear 3 will rotate along the direction perpendicular to paper.
Referring to Fig. 3, in the inside of second helical gear 3, offer threaded through hole along pivot center b-b (it is perpendicular to the paper of Fig. 2), the screw thread that matches is offered can screw in this through hole in the surface of locking bar 4.When second helical gear 3 when axis b-b rotates, will parallel to the axis b-b direction generation precession or revolve and move back motion of locking bar 4, thus insert or withdraw from lockhole 5.As shown in Figure 3, the end that locking bar 4 can stretch into lockhole 5 is tip shape, correspondingly, near lockhole 5 openings aperture then inwardly dwindles gradually, like this, as long as the sharp end of locking bar 4 and the EDGE CONTACT of lockhole 5 openings, just can under the guiding of lockhole 5 inner surfaces, be headed into exactly in the lockhole 5.Obviously, said here tip shape is including, but not limited to taper.
When locking bar 4 when lockhole 5 reclaims (being that the locking bar along continuous straight runs is moved to the left), in order to prevent that locking bar 4 from rotating after returning installing plate 9 fully, clamp 7 is set as limiting component in this preferred embodiment, as shown in Figure 3, clamp is fixed on the side of second helical gear 3 away from lockhole 5, offer breach or screw on this clamp, correspondingly, but the external diameter of the end that locking bar 4 is relative with sharp end and breach bore or screw aperture are quite less than the external diameter of locking bar stage casing part.
Under user mode, parts such as motor 1, first helical gear 2, second helical gear 3, locking bar 4 and clamp 7 are installed on the frame 6 to constitute the lock core part of locking mechanism, frame 6 is fixed on the framework of door and window by installing plate 9, the upper and lower side frame of framework for example, and lockhole is installed on the fan body and is closing the position corresponding with locking bar 4.Like this, when fan body was in locking bar 4 with position that lockhole 5 is aimed at substantially, the driving force that motor 1 provides drove to locking bar 4 by first and second helical gears 2 and 3, drove it and stretched into or withdraw from lockhole 5, thereby realize locking or release action.
It is worthy of note, frame 6 in the foregoing description is not requisite parts, in fact parts such as motor 1, first helical gear 2, second helical gear 3, locking bar 4 and clamp 7 can directly be installed on the installing plate 9 or in the lock housing 8, and the variation on this mounting structure can not produce substantial influence to the helical gear kind of drive and locking bar and lock housing locate mode.
