Abstract

The utility model relates to a lock gearing means. A driven piece and a shifting block are arranged at the head part of a locking head mandrel, on the basis of the existing structure composed of a locking head, a locking head mandrel and a key hole, a key can drive the shifting block arranged on the locking head mandrel and then drive the driven piece through the shifting block, and a driving head of the driven piece can drive parts in a lock body. The key can be veered or turned reversely and then is pulled out in the same position to close the lock in two different positions with two different limiting ways.

Description

The tapered end transmission device

The utility model relates to lockset and makes field, a kind of specifically tapered end transmission device.

At present, traditional tapered end transmission device is to drive the tapered end mandrel by key, and the tapered end mandrel drives the driver blade that is fixed on tapered end mandrel head, again by the corresponding part in the driver blade drive lock body, reaches the purpose of transmission.This kind of drive exists weak point, because the tapered end mandrel only can extract key out a position usually, therefore, reaches two control positions lockset is carried out several ways to restrain as locking and not locking by the above-mentioned kind of drive is difficult.

The purpose of this utility model provides a kind of tapered end transmission device, and it has overcome the shortcoming that prior art exists.

The purpose of this utility model is achieved in that it is made up of tapered end, tapered end mandrel, and driven disc is equipped with by shifting block in the front portion of described tapered end mandrel; Have axis hole on the described driven disc, driven disc is sleeved on the tapered end mandrel, and an end of driven disc is provided with driven head and driving head; Described shifting block is fixed on the tapered end mandrel in the driven disc outside, and shifting block can be card or pin.

Owing to taked such scheme, can reach two kinds of different control modes by the tapered end transmission device to lock body, simplified the inner further drive mechanism of lock body, and only increased by a driven disc, simple in structure.

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model building block decomposing schematic representation.Among the figure: 1. tapered end; 2. tapered end mandrel; 3. driven disc; 4. shifting block; 5. keyhole; 6. driven head; 7. driving head.

After inserting keyhole 5 and drive shifting block 4 on tapered end mandrels 2 and the tapered end mandrel 2 and rotate by the key (not shown) during use, thereby shifting block 4 drives driven 6 makes the driving head 7 on the driven disc 3 rotate the corresponding part (not shown) of drive lock body, lock body does not belong to inventive point of the present utility model, so do not elaborate.When the different conditions of control lock, after only needing the clockwise or reversing of a key, tapered end mandrel 2 make shifting block 4 from the left side or the right stir driven disc 3, can guarantee that like this key extracts out from same anchor point, and driven disc 3 can forward two different positions to, thereby reaches the purpose that makes dead bolt that two kinds of different state of a controls be arranged.

Claims

1. tapered end transmission device, by tapered end (1), tapered end mandrel (2), form, it is characterized in that: driven disc (3) is equipped with by shifting block (4) in the front portion of described tapered end mandrel (2).

2. tapered end transmission device according to claim 1 is characterized in that: described driven disc has axis hole on (3), and driven disc (3) is sleeved on the tapered end mandrel (2), and an end of driven disc (3) is provided with driven head (6) and driving head (7).

3. tapered end transmission device according to claim 1 is characterized in that: described shifting block (4) is fixed on the tapered end mandrel (2) in driven disc (3) outside, and described shifting block (4) can be card or pin.
