Abstract

The utility model relates to a lock with an edge-arc key, which is mainly composed of the edge-arc key, a vane, a lock body, a lock core, etc. A lack slot is arranged on the outer circle of the lock core so as to be clamped directly by the lock core or a lock beam or a lock bolt is released. A driving mechanism is omitted. So working procedures can be simplified and failures can be reduced. The lock with an edge-arc key is matched on various locksets to use.

Description

The Arc-key tapered end

The utility model relates to a kind of tapered end, specifically, relates to a kind of tapered end of opening or closing with Arc-key.

Arc-key tapered end in the past, lock core block or discharge lock bridge or dead bolt need have the transmission mechanism transmission, and this makes its finished parts and assembling procedure comparatively numerous and diverse, breaks down easily in the use.

The purpose of this utility model is to save transmission mechanism, thereby simplifies working process, reduces fault.

Above-mentioned purpose is by providing the Arc-key tapered end with following structure to realize: it comprises Arc-key, blade, tapered end and lock core etc., is shaped on short slot on the lock core cylindrical, and when the short slot correspondence was colluded groove, lock bridge or dead bolt can move along short slot.Short slot leaves when colluding groove, and lock bridge or dead bolt are blocked by lock core.

Owing to be shaped on short slot on the lock core, then can directly block or discharge lock bridge or dead bolt, thereby omit transmission mechanism, so operation is simplified the fault minimizing by lock core.

Below in conjunction with description of drawings plurality of embodiments of the present utility model:

Fig. 1, Arc-key tapered end assembling schematic diagram.Fig. 2-Fig. 8, lock core front view.

Fig. 9, blade front view.Figure 10-Figure 13, lock core and lock bridge or dead bolt section assembling schematic diagram.

As shown in the figure, the utility model is made up of Arc-key 1, blade 4, tapered end 3 and lock core 2 etc., is shaped on tapered end blade groove 5 on its tapered end 3; 6 both sides, middle part of Arc-key 1 are curve-likes such as sine or cosine; Spoon passes mouth 8 and is the passage shape; Blade 4 is frame-like, and the internal orifice of blade 4 has breach 14 for 13 4 jiaos and is beneficial to angle clearly; Circlip 7 connects lock core 2 and tapered end 3.This type of tapered end is disclosed by following patent documentation in the prior art: Chinese patent CN2258523Y, CN2258527Y (bulletin on July 30th, 1997); CN2230340Y (bulletin on July 3rd, 1996).On the basis of existing technology, make short slot 10 on the cylindrical of lock core 2, as Fig. 2-shown in Figure 8, short slot 10 can be positioned at that the shoulder of lock core 2 is 9 other, by lock core blade groove 11 sides that can be positioned at lock core 2, can be positioned at the rear end of lock core 2; And can be one-sided, also can be bilateral; Be positioned at also can connecting of rear end with rear end face 12.The position of described short slot 10, one-sided or bilateral and connect or do not connect with rear end face and can make up employing are to adapt to various enforcement needs.

As Figure 10-shown in Figure 12, with Arc-key 1 lock core 2 was gone to short slot 10 corresponding lock bridges (or dead bolt) at 16 o'clock, lock bridge (or dead bolt) 16 can move along short slot 10, move on the lock bridge (or dead bolt) 16 collude the short slot 10 of groove 15 corresponding lock cores 2 time, with Arc-key 1 with lock core 2 rotation alpha angles, lock bridge (or dead bolt) 16 is stopped by the position beyond the short slot 10 of lock core 2 promptly and blocks that extract Arc-key 1, tapered end is then closed.When opening tapered end, insert Arc-key 1 with lock core 2 reverse rotation α angles, lock bridge (or dead bolt) 16 is released, can moves along short slot 10 again, and tapered end is then opened.

Above-described only is preferred implementation of the present utility model, and under the prerequisite that does not break away from its principle, persons skilled in the art also can be made some modification and improvement, and this falls into protection domain of the present utility model certainly.
