Embodiment

The utility model is described further below in conjunction with the accompanying drawings：

Below by way of specific embodiment, the utility model is described in further detail, but not to limit the utility model, it is all Within spirit of the invention and principle, any modification, equivalent substitution and improvements made etc., it should be included in of the present utility model Within protection domain.

Embodiment

As shown in Figure 1 and Figure 2, it is described for anti-theft safety door locking device latching device, including two be engaged lock Runner 1 and expense plectrum 2, offered in runner 1 of locking for the central rotation hole 1.1 of installation and for spacing spacing cunning Groove 1.4；Limit sliding chutes 1.4 are arcuate structure, the center of circle of rotating hole 1.1 centered on its arc core；Offered in the one end of expense plectrum 2 For the swing rotary hole 2.1 of installation, the expense that the other end of expense plectrum 2 is provided with for stirring touches end 2.5；Turn locking Offered on wheel 1 and lock mouth 1.2 for the hook of locking, latch hook is provided with the runner 1 of locking on the right side of hook locking mouth 1.2 The inner 1.3, is provided with walking surface 2.2 inside the latch hook being rotatably assorted with latch hook the inner 1.3, in latch hook on expense plectrum 2 Being provided with expense plectrum 2 between portion's walking surface 2.2 and expense touching end 2.5 prevents the lock that runner 1 turns clockwise of locking Hook the inner block machine 2.3, latch hook the inner block machine 2.3 and expense touching end 2.5 between expense plectrum 2 on be provided with latch hook Latch hook the inner contact surface 2.4 that end 1.3 is engaged；It is provided between expense plectrum 2 and runner 1 of locking for expense plectrum 2 make the actuating unit to turn clockwise.

In the present embodiment, the actuating unit includes extension spring 3, and the one end of extension spring 3 is connected with expense plectrum 2, its other end with Runner 1 of locking connects, and its is simple in construction, easy for installation, and production cost is low.In use, other engines can also be used Structure, the torsion spring that the runner 1 that makes to lock turns clockwise such as is installed in runner 1 of locking, an inverse time is installed on expense plectrum 2 The torsion spring that pin is swung.

The extension spring 3 is connected on the expense plectrum 2 between expense touching end 2.5 and latch hook the inner contact surface 2.4, is used Effect is very good, operates steadily.

The limit sliding chutes 1.4 are symmetrical set with latch hook the inner 1.3；The hook locking mouth 1.2 is arcuate structure, side Just coordinate with hook (generally hook is cylindrical structural).

Functional principal, when the hook of local hook initially enters hook locking mouth 1.2, hook heads on runner 1 of locking and does up time Pin rotates, and when latch hook the inner 1.3 rotates up out from latch hook the inner walking surface 2.2, hook will be locked in hook locking mouth 1.2 In the lock space of the composition of latch hook the inner 1.3, in the presence of extension spring 3, expense plectrum 2 is pulled into (expense to runner 1 of locking Plectrum 2 turns clockwise along central rotation hole 1.1, and expense plectrum 2 does counter-clockwise swing along swing rotary hole 2.1) so that will Latch hook the inner 1.3 is close together with latch hook the inner contact surface 2.4；Latch hook the inner block machine 2.3 will be kept off in latch hook the inner 1.3 simultaneously Lower end, (it is effectively prevented artificially that hook locking mouth 1.2 is downward so as to effectively prevent the rotate counterclockwise of runner 1 of locking Dial, so as to open hook locking mouth 1.2).When it is dynamic stir expense touching end 2.5 to the right when, latch hook the inner block machine 2.3 is from lock 1.3 lower ends of hook the inner are removed, and relieve the limitation that runner 1 turns clockwise of locking.

During installation, spacer pin is set in limit sliding chutes 1.4, in the presence of spacer pin, hook locking mouth 1.2 can be prevented During in open mode, runner 1 of locking continues to turn clockwise.

The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.This The technical staff of industry is retouched in above-described embodiment and specification it should be appreciated that the utility model is not restricted to the described embodiments That states is merely illustrated the principles of the invention, and on the premise of the spirit and scope of the utility model is not departed from, the utility model can also There are various changes and modifications, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model will Protection domain is sought by appended claims and its equivalent thereof.
