detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of bar lock of this embodiment. The lock includes a lock body 11 , a toggle bar 14 , a lock hook seat 20 and a lock hook 23 . A rectangular opening 111 is processed on the lock body 11, and the toggle bar 14 is movably mounted on the lock body 11, and the toggle bar 14 can be toggled by hand through the opening 111. A toggle slot 142 is processed on the toggle bar 14 , and the toggle slot 142 corresponds to the opening 111 , and a relief opening 141 is processed on the toggle bar 14 near the toggle slot 142 . On the toggle bar 14, a mounting hole is processed near the lower end of the toggle bar 14. A spring 15 is housed in the mounting hole. The matching positioning groove of the two steel balls 16 makes the positioning sense stronger when the toggle bar 14 is toggled up and down. A limit pin 25 for limiting the position of the toggle bar 14 is fixed on the lock body 11 close to the upper end of the lock body 11 by riveting. Lock hook seat 20 is fixed on the upper end of toggle bar 14, and lock hook seat 20 is processed with draw-in groove, and slide block 21 is housed in this draw-in groove, and this slide block 21 can move in draw-in groove, slide block 21 and lock hook seat 20 forms an adjusting screw hole, and an adjusting screw 22 is sleeved in the adjusting screw hole. Locking screw holes are processed on the locking hook seat 20, and the locking screw holes communicate with the draw-in groove. The locking screw holes correspond to the relief opening 141, and the locking screw 19 for fixing the slide block 21 is sleeved therein. Two cross-recessed pan-head screws pass through the lock hook 23 and are threaded with the slider 21, thereby fixing the lock hook 23 on the slider 21. One end of the lock hook 23 is processed into a slope to strengthen the guide and make the lock hook 23 better. Ground into the lock seat (not shown in the drawings), especially suitable for narrow profiles. In a preferred design, the locking screw 19 is designed as a set screw with a flat end of a hexagon socket.

In a preferred design, a green mark 17 and a red mark 18 are respectively installed on the two ends of the toggle bar 14 close to the toggle groove 142 , wherein the green mark 17 covers the locking screw 19 . The green mark 17 and the red mark 18 respectively play an indicative role, and the green represents opening, and the red represents closing, and can prevent dust or other sundries from entering the inside of the bar lock simultaneously.

Referring to FIG. 4 , when the bar lock of the present invention is installed, the bar lock is fixed on the door leaf 26 by two fixing screws 13 and two pressing plates, wherein the two pressing plates hold the door leaf 26 .

The principle of the bar lock of the present invention: Referring to Figure 4, pull out the green mark 17, loosen the locking screw 19 through the wrench 27, and twist the adjusting screw 22 through the wrench 27 to move and adjust the locking hook 23 left and right, and the locking hook 23 can be adjusted left and right Measure ±3.5mm, after the adjustment, tighten the locking screw 19 to make it press the slider 21, so as to realize the adjustment of the locking hook 23.
