Background technique

The conventional push-pull door and window lock device is to use the shape drop of a certain part in the lock to fasten another fixed part to achieve the purpose of locking. However, only by the physical action of the dislocation of the two parts to lock, a certain gap must be left. It is these gaps and certain structural relationships that make the door and window leaf just have a chance to be released due to the vibration of external force, and lose the locking and anti-theft function.

Utility model content

The purpose of this utility model is to solve the above-mentioned problems and deficiencies, and provide a sliding door and window lock device with high anti-theft performance. It falls off due to the vibration of external force, the design is reasonable and the structure is simple, the anti-theft performance is good, and the safety is good.

The technical scheme of the utility model is achieved in that:

A sliding door and window lock device with high anti-theft performance, which is characterized in that it includes a lock base, a toggle panel, a toggle piece, a lock plate, a lock bar assembly and a shrapnel, wherein

The toggle panel is installed on the front of the lock base, and a sliding cavity groove is also provided on the bottom surface of the lock base, the toggle piece is installed in the slide cavity groove, and the toggle piece is connected with the toggle panel;

A concave cavity is also made on the side of the sliding cavity groove of the lock seat, and a pin shaft is arranged on the concave cavity. One end of the locking piece is made with a shaft hole, and the other end of the locking piece is made with a bent portion. The lock plate is installed in the cavity of the lock seat by connecting the shaft hole with the pin shaft;

The torsion spring is installed in the lock seat, one end of the torsion spring is engaged with the curved portion of the locking plate, and the other end of the torsion spring leans against the toggle piece;

The lock bar assembly is composed of a lock bar and a fixed bottom, and a screw hole is also provided on the fixed bottom; a lock bar hole is also provided in the middle of the lock plate, and the lock bar of the lock bar assembly and the lock bar hole of the lock plate phase socket;

The shrapnel is installed in the sliding cavity groove on the surface of the toggle piece.

The beneficial effects of the utility model: the push-pull door and window lock device achieves the purpose of locking by changing the axis angle of the circular hole and the circular shaft, and will not fall off due to the vibration of the external force. The design is reasonable and the structure is simple, and the anti-theft performance is good. Safe and good.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, a sliding door and window lock device with high anti-theft performance described in the utility model includes a lock seat 1, a toggle panel 2, a toggle member 3, a torsion spring 4, and a lock plate 5. Lock bar assembly 6 and shrapnel 7, wherein

As shown in Figure 1 and Figure 3, the toggle panel 2 is installed on the front of the lock base 1, and a sliding cavity 11 is also provided on the bottom surface of the lock base 1, and the toggle member 3 is installed in the sliding cavity 11 , and the toggle piece 3 is connected with the toggle panel 2 to control the toggle piece 3 to move back and forth along the sliding cavity groove 11 through the toggle panel 2 .

As shown in Figure 3, a concave cavity 12 is also formed beside the sliding cavity groove 11 of the lock base 1, and a pin shaft 8 is arranged on the concave cavity 12, and a shaft hole 51 is formed at one end of the locking piece 5, The other end of the lock piece 5 has a bent portion 52 , and the lock piece 5 is connected with the pin shaft 8 through its shaft hole 51 and installed in the cavity 12 of the lock base 1 . The torsion spring 4 is installed in the lock seat 1 , one end of the torsion spring 4 engages with the bent portion 52 of the locking plate 5 , and the other end of the torsion spring 4 leans against the toggle member 3 .

As shown in Figure 3, the locking rod assembly 6 is composed of a locking rod 61 and a fixed bottom 62, and a screw hole 63 is also provided on the fixed bottom 62; a locking rod hole 53 is also provided in the middle of the locking plate 5, and The locking rod 61 of the locking rod assembly 6 is socketed in the locking rod hole 53 of the locking piece 5 .

As shown in Figure 3, the elastic piece 7 is installed in the sliding cavity groove 11 on the surface of the toggle piece 3 to form an elastic downward pressing effect on the toggle piece 3, so as to prevent the toggle piece 3 from loosening. Phenomenon, so that the whole lock has a certain feel when it is toggled.

In addition, as shown in FIG. 2 , a lock case 9 is installed at the position of the concave cavity 12 of the lock base 1 , and a lock hole 91 corresponding to the lock rod hole 53 of the lock plate 5 is provided on the lock case 9 . So that the locking rod 61 of the locking rod assembly 6 can be socketed with the locking rod hole 53 of the locking plate 5 after passing through the locking hole 9 .

The working principle of the utility model is roughly as follows: when locking, push the toggle panel 2, the toggle panel 2 drives the toggle piece 3 to move along the sliding cavity groove 11, and under the cooperation of the torsion spring 4, the lock plate 5 wraps around the pin The shaft 8 swings, and its locking rod hole 53 is socketed with the locking rod 61 of the locking rod assembly 6 . Because the fixed bottom 62 of the lock bar assembly 6 is fixed on the window frame, it is immobile. When the lock plate 5 rotates clockwise, the position of the lock plate 5 is limited by the pin 8, and the lock bar hole 53 and the pin The axis angle formed by 8 increases thereupon, so that the lock bar hole 53 bites the lock bar 61 more tightly, thus playing the anti-theft effect of cross prying. In addition, because the gap between the lock bar hole 53 and the lock bar 61 is limited, the radial range of movement of the lock bar 61 in the lock bar hole 53 is not large, thereby achieving the anti-theft purpose of prying up and down. When unblanking, toggle member 3 resets, and locking plate 5 is lifted, and the axis angle of locking bar hole 53 and bearing pin 8 is changed, and the upper and lower diagonal points of locking bar hole 53 leave locking bar 61, complete the operation of unblanking.
