The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1～4, present embodiment includes tapered end 6, spring 44, fork 31 and latch hook 4, latch hook 4 has two, see illustrated in figures 1 and 2, between the two cover plates 1 before and after being fixed in, can relatively rotate by turning cylinder 42 and cover plate 1, this two latch hook 4 is interconnected movably by interlock plate 7.Described tapered end 6 is between two latch hooks 4, and the mounting hole 71 (seeing the dotted portion of Fig. 4) that passes on the interlock plate 7 fixes with front shroud 1, tapered end 6 a part stretch into before and after in the inner chamber formed of two cover plates 1, see shown in Figure 3, its another part is positioned at the external surface of cover plate 1, and by screw 61 tapered end 6 and cover plate 1 is fixed together.The both ends that tapered end 6 is built-in with rotating lock core 3, lock core 3 have keyhole 32.Described lock core 3 its inside are provided with big differential blade (not drawing among the figure), blade differential at 0.5-0.8mm, and the quantity of blade is 6, and to be arranged in together unconventionally.Strengthen the theftproof performance of lockset so effectively, also reduced the mutual opening rate of lockset simultaneously widely.Two cover plates 1 was formed on the lock core 3 in the inner chamber before and after described fork 31 was fixed in, and linked together with tapered end 6 rotationally with lock core 3.Be respectively arranged with the lock 43 that contacts mutually with spring 44 in two latch hooks, 4 inside, lock 43 is " T " font, on " T " font mobile jib 45, be provided with little mounting hole 41, see shown in Fig. 1 and 2, these little mounting hole 41 cover strings are on the turning cylinder 42 of latch hook 4, in " recessed " font locating hole 14 before and after " T " font two side arms of lock 43 is fixed on respectively movably on the two cover plates 1, and mobile jib 45 1 ends of lock 43 to be its tail end unblanking or contacting cooperation mutually with rotating fork 31 during blocking.Because the existence of lock 43 when locking, is locked as the master with lock 43, lock core 3 is locked as auxilliary, has alleviated the pressure of tapered end 6 lockings greatly.Described cover plate 1 its two ends are provided with " 7 " font fixed block 12, and front and back two cover plates 1 are fixed together, and have can make the through hole 11 that connecting rod 5 passes and lockset can be fixed in the locational screw 12a of required door and window on fixed block 12.Described connecting rod 5 is fixed on two latch hooks 4 of side in the same way, and is positioned at rotating shaft 42 positions of departing from latch hook 4.

As Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, be that auxilliary lock construction is looked intention, as we can see from the figure, described auxilliary lock is provided with a latch hook 8 (its structure no longer be repeated in this description) identical with main body latch hook 4 structures, before and after it is rotatably mounted to equally in two the jam plate 9, the side of latch hook 8 and be fixed with the connecting rod 81 that links to each other with body lock departing from latch hook 8 rotating shafts 82 positions.Described jam plate 9 its two ends also are provided with fixed block 92 front and back two jam plates 9 are fixed together, and have the through hole 91 that connecting rod 81 is passed and lock due to the locational screw 92a of required door and window with assisting on fixed block 9.

Operating principle: when move door, window or overhead door, when window is closed, with key rotary locking cylinder 3, lock core 3 drives shift fork 31, after locks 43 in the latch hook 4 are overcome spring 44 pressure, stirring latch hook 4 simultaneously is that the latched position that (interior armful or translate in the hole of another fan or doorframe and window frame) slips into lock 43 " recessed " font locating hole 14 is rotated at the center outward with latch hook rotating shaft 42, the spring 44 of lock 43 is replied locking, otherwise promptly opens.Latch hook 4 is provided with the connecting rod 5 that can link to each other with auxilliary lock connecting rod 81, can be according to the length or the height of door and window, and decision increases one or more auxilliary locks, thereby forms the more piece locking.Be characterized in, adopt rotate latch hook 4 and reduced the lockset volume, be adapted at directly installing in the square tube of door-window section bar, install simple and conveniently, and alleviated the lock pressure of tapered end 6 by lock 43.
