Description

Folding key

The utility model folding key, it relates to a kind of key, and feature is the collapsible key that key bow and the shank of the key flexibly connect.

Existing market is sold and key commonly used is the straight handle type key that the key bow continued to use for many years and the shank of the key are fixed as one, and its major defect is longer dimension, carry inconvenience, twist off easily or fracture etc.

Be the shortcoming avoid above-mentioned prior art to exist, the utility model provide a kind of handsome in appearance, be easy to carry, folding key that key bow and the shank of the key flexibly connect.

The purpose of this utility model is achieved in that a kind of folding key of being made up of key bow and the shank of the key, key bow is semi-circular, two ends is 90 ° of bendings relatively and constitutes card base, the shank of the key bottom is a contiguous block, its two ends are provided with draw-in groove relatively and are connected slotted eye, and draw-in groove is parallel with the shank of the key, connect slotted eye and card base and are movingly, card base can rotate 360 ° in slotted eye, the shank of the key has the single or double key bit.

Description of drawings is as follows:

Fig. 1 is the folding key structural representation

Fig. 2 is a shank of the key contiguous block schematic cross-section

Fig. 3 is a folding key deployed condition schematic diagram

1-key bow 2-the shank of the key 3-draw-in groove 4-connects slotted eye 5-card base 6-contiguous block among the above figure

Below in conjunction with accompanying drawing the utility model is further described: referring to Fig. 1 and Fig. 2, the folding key of forming by key bow (1) and the shank of the key (2), key bow (1) is semi-circular, two ends is 90 ° of bendings relatively and constitutes elasticity card base (5), the shank of the key (2) bottom is contiguous block (6), its two ends are provided with draw-in groove (3) relatively and are connected slotted eye (4), and card base (5) inserts in connecting slotted eye (4).Draw-in groove (3) is parallel with the shank of the key (2), plays the shank of the key (1) positioning action; Connect slotted eye (4) and be movingly with card base (5), card base (5) can rotate 360 ° in slotted eye.The single or double key bit can be made in the shank of the key (2) both sides.Key bow (1) can adopt the compacting of 60Mn steel wire; The available zinc alloy diecasting moulding of the shank of the key (2).When not using, the shank of the key (2) is gone in the key bow (1), locate by draw-in groove the key bow both sides, and the shank of the key (2) is shielded.During use, the shank of the key (2) produced in the key bow (1) be deployed condition (referring to Fig. 3).

The utility model is relative with prior art to have the following advantages: simple in structure, handsome in appearance, size is little, be easy to carry, be difficult for twisting off or fractureing.
