Abstract

The utility model relates to a vane lock with an edge-arc key, which is mainly composed of the edge-arc key, a lock core, a lock body, a vane, etc. The back end of the lock core is provided with a passage-shaped key passing opening for positioning a tip part of the edge-arc key. The working procedure of riveting a driving piece with an opening is relieved. The assembly is compact, and the efficiency is improved. The vane 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, particularly a kind of Arc-key tapered end.

The tip that Arc-key tapered end in the past is with the driver blade location Arc-key of opening with riveted joint, this makes, and its assembling is comparatively numerous and diverse, efficient is lower.

The purpose of this utility model is to overcome above-mentioned defective, and a kind of assemble succinct, the higher Arc-key tapered end of efficient are provided.

Above-mentioned purpose is realized by following technical scheme: have a spoon biography mouth in the lock core rear end, spoon passes mouth and is the passage shape, and the cross section does not have given shape, can adopt the degree of lip-rounding, circle, polygon or irregular shape; The size of size and Arc-key tip is worked in coordination, with the tip of location Arc-key.

Have passage shape spoon and pass a mouthful Arc-key tip, location, exempted staking process in the past, so its assembling is more succinct, efficient is higher.

The explanation of accompanying drawing drawing:

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

Fig. 3. the blade front view.Fig. 4. the Arc-key schematic diagram.

Fig. 5-Figure 15. the different spoons of lock core shown in Figure 2 pass the vertical view of mouth.

Among the figure: 1, Arc-key; 2, lock core; 3, tapered end; 4, blade; 5, blade groove; 6, hole; 7, driver blade; 8, circlip; 9, driver blade pin-and-hole; 10, spoon passes mouth; 11, lock core blade groove; 12, internal orifice; 13, tip.

Below in conjunction with description of drawings embodiment of the present utility model: as shown in the figure, the utility model mainly is made up of Arc-key (1), lock core (2), tapered end (3) and some blades (4) etc., has spoon on its lock core (2) and passes mouthful (10).Spoon passes mouthful (10) and is positioned at lock core (2) rear end, be the passage shape, cross sectional shape does not have particular requirement, can adopt the degree of lip-rounding, circle, polygon or irregular shape shown in Fig. 5-15, as long as the size of the tip (13) of its size and Arc-key (1) is worked in coordination, make tip (13) pass the tip (13) that lock core (2) play radially that can do lock core (2) axially-movable in the mouth (10) smoothly, not produce the out-of-size scope again can be located Arc-key (1) at spoon.When spoon biography mouthful (10) can be made lock core (2) in die casting or with powder metallurgy, later stage staking process was in the past exempted in one-shot forming simultaneously.The making of all the other component, prior arts such as assembling and use see also July 30 1997 Chinese patent notice of authorization CN2258527Y notice of authorization day, the manual in March 27 1998 year notice of authorization CN2289021Y notice of authorization day.It is to be noted that here internal orifice (12) length of each blade (4) not necessarily equates; Two guide angles (β d) of the tip (13) of Arc-key (1) not necessarily equate; The both sides millable undulate of Arc-key (1), but the distance between two curves not necessarily equates.

Claims

1, a kind of Arc-key tapered end, it has lock core (2), it is characterized in that having spoon in lock core (2) rear end passes mouthful (10), and spoon passes mouthful (10) and is the passage shape.

2, a kind of Arc-key tapered end as claimed in claim 1 is characterized in that the cross section of spoon biography mouthful (10) does not have given shape, can adopt the degree of lip-rounding, circle, polygon or irregular shape.

3, a kind of Arc-key tapered end as claimed in claim 1 or 2 is characterized in that spoon passes the size of mouthful (10) and the size of Arc-key (1) tip (13) is worked in coordination, with the tip (13) of location Arc-key (1).
