Abstract

The utility model relates to an annular slot vane lock which is a mechanical lock composed of an arc key and an annular vane. The annular slot vane lock is characterized in that the arc of a key (1) is matched with the outer circle of a lock core (10), and the annular vane (12) is used for controlling the motion of a key bar (9); the key bar (9) is used for controlling the rotation or the latching state of the lock core, and a key sheet (2) and various springs are arranged. The lock uses the annular vane and the key bar to control the lock core so as to greatly enhance the performance of preventing technical opening. The annular slot vane lock has simple and compact structure, beauty and durable use, and the annular slot vane lock can be widely applicable for various locksets and doors.

Description

The circular groove type Mortise lock

1, technical field:

The utility model " circular groove type Mortise lock " relates to the mechanical type tapered end of a kind of annular page or leaf sheet and arc key.

2, technical prospect:

The tapered end major part of Xiao Shouing all is directly to control the rotation of lock core with pellet shot from a slingshot or page or leaf sheet in the market, and more or less freely by the robber with technical unlocking or destruction, be difficult to satisfy modern's pursuit.And the utility model has adopted the rotation of key bar control lock core, has strengthened preventing the performance of technical unlocking.I had once also mentioned the principle of utilizing key bar control lock core to rotate in the patent design of ZL.97208961.6 and ZL01255613.0, the utility model has utilized annular page or leaf sheet and arc key to cooperate the principle of utilizing the key bar again, make the utility model more reasonable structure, both artistic and practical, theftproof is stronger, and can successfully address the above problem.

3, summary of the invention:

The purpose of this utility model provides a kind of mechanical type tapered end of annular page or leaf sheet operating key bar: it is provided with the multiple tracks annular groove at the lock core place, annular page or leaf sheet is housed in annular groove, and the tartar that passes through arc key both sides is controlled the rotational angle of annular page or leaf sheet, when a plurality of pages of sheets go to suitable angle simultaneously, the key bar just can slip in the lock core cover automatically, lock core and lock core are enclosed within the tapered end hole to rotate flexibly, after extracting key, by the spring in the annular groove annular page or leaf sheet being rotated under page effect on sheet sloping platform rank outwards moves the key bar, slipping into tapered end hole inside groove can not rotate lock core, and reach the purpose of locking, for increasing size of key and strengthening theftproof, when being installed, can use simultaneously (as Fig. 3 the page or leaf sheet by both forward and reverse directions, shown in Figure 6).When the page or leaf sheet goes to second step, the key bar can not be again moved outward, page sheet can not be rotated again and reach page purpose (as shown in Figure 7) of sheet location.And set up the spoon door and made up, loxosis by spoon door sheet cooperates with the gradient that key is chewed, and when inserting key, the sector-meeting of spoon door moves up automatically, after extracting key, the effect by spring makes spoon door sheet reach sealing keyhole and dustproof effect (as shown in Figure 2) automatically downwards.Thereby realized making this utility model more reasonable structure, attractive and durable, easy to use, theftproof is strong, can be widely used in the upward use of all types of locksets and door.

The utility model is achieved by the following scheme: form complete lock head structure by key, lock core, lock core cover, annular page or leaf sheet, key bar, tapered end cover, anti-drill pin, spacer pin and spoon door sheet and spring steel ball etc.When inserting key, the sector-meeting of spoon door is moved automatically, and each group page or leaf sheet goes to proper angle according to tartar, the key bar is slipped in the lock core cover lock core can be rotated flexibly, each page sheet automatically resets under the effect of spring with a spoon door sheet after extracting key, thereby reaches the effect of locking and sealed key hole.

5, the specific embodiment:

As Fig. 1～shown in Figure 7, it comprises: in the hole that the lock core (10) of at first spacer (13) being packed into is preset, and an annular page or leaf sheet (12) is assemblied in the annular groove of lock core (10) by the tartar of key (1) both sides, and load onto spring (14), put into spoon door sheet (2) and spring (3) again, lock core cover (4) endoporus of packing into then, and squeeze into anti-drill pin (15), lock core and lock core cover are fused, in the default groove of lock core cover, put into key bar (9) again, and then put tapered end into and overlap endoporus, in the default hole of tapered end cover, put into steel ball (8) and spring (6) again, squeeze into sealing bead (7) again, squeeze into spacer pin (11) at last, (note: spacer pin can replace with jump ring), just finished complete circular groove type Mortise lock.
