Description

I-shaped-key cucurbit tapered end

Technical field:

The utility model is relevant with lock, the particularly a kind of I-shaped-key cucurbit tapered end that can open from all available I-shaped-key in two sides of lock.

Background technology:

General lock head device, the one end offers keyhole, plant for key, and its other end is provided with one group of bar, this group bar stretches into the installation hole of locking closure, when dialling the hoodle that bar can be in key drives tapered end and hoodle rotate synchronously, to finish unlocking action.These structures are single hoodle mostly, no matter therefore how many hoodles it adopts arrange, when the thief uses steel wire or other similar tool to stretch into lockhole, be easier to open lockset, its safety is relatively poor, and the inventor had once proposed a kind of high safe low wrong-unlocking rate I-shaped-key tapered end (patent No.: ZL00217544.4), safety is improved greatly, keep low wrong-unlocking rate, and structure and uncomplicated.

The utility model content:

The technical problems to be solved in the utility model is exactly according to the above-mentioned patented technology (patent No.: ZL00217544.4) also improved, a kind of I-shaped-key cucurbit tapered end is provided, this tapered end should be safer, it is more smooth to adopt corresponding I-shaped-key to open, and can be equipped with inside and outside the door of this tapered end, promptly from the bilateral tapered end of tapered end with the I-shaped key unlocking.

Technical solution of the present utility model is as follows:

A kind of I-shaped-key cucurbit tapered end, form by gourd type lock, lock core, I shape key, lock core is set in the gourd type lock and fixes with collar, the two ends of gourd type lock and lock core are provided with a plurality of corresponding slotted eyes vertically, be filled with down pearl in the slotted eye from bottom to top, go up pearl, upper bead spring and sealing bead, its characteristics are:

1. lock core is divided into two sections, and its both ends respectively are provided with the side control piece that elastic body holds a slip accordingly;

But 2. be respectively equipped with the circular arc elongated slot of inlay card side control piece corresponding to the side control piece in the lock core in the gourd type lock both sides;

3. this side control piece inboard is provided with at least one double wedge, and this double wedge has the hypotenuse structure, and the outside of side control piece is provided with the circular arc raised line of the circular arc elongated slot that can embed or skid off lock body;

The spoon body of 4. said I shape key is provided with side channel, and this side channel has the hypotenuse structure, and is corresponding with the hypotenuse structure of the double wedge of said side control piece.

The I shape keyhole at said lock core two ends is secundly slightly all, and the tip of pearl and the flange of I shape keyhole are close, and the hoodle on the spoon body two sides of said I shape key is cheated also secundly, makes it most advanced and sophisticated corresponding with following pearl.

The specific embodiment:

See also Fig. 1 to Figure 11.The utility model I-shaped-key calabash shape tapered end is made up of gourd type lock 1, lock core 15 and I shape key 3, lock core 15 and fixing with collar 21 is set in the gourd type lock 1, the two ends of this gourd type lock 1 and lock core 15 are provided with a plurality of corresponding slotted eyes vertically, be filled with down pearl 14 in the slotted eye from bottom to top successively, go up pearl 13, upper bead spring 12 and sealing bead 11, be characterized in:

1. lock core 15 is divided into two sections, is provided with connector 19, connector riveted pipe 17 and lock core dialing part 18 between two sections, and lock core 15 two ends respectively are provided with the side control piece 20 that elastic body 202 holds a slip accordingly;

2. be respectively equipped with the circular arc elongated slot 101 of this side control piece 20 of inlay card corresponding to the side control piece 20 in the lock core 15 in gourd type lock 1 both sides;

3. these side control piece 20 inboards are provided with at least one double wedge 203, and this double wedge 203 has the hypotenuse structure, and this double wedge 203 is in manufacture process, and the degree of depth and the width of its quantity and each between cog position, tooth all can change, thereby can make this type lock can obtain minimum wrong-unlocking rate; The outside of side control piece 20 is provided with the circular arc raised line 201 of the circular arc elongated slot 101 that can embed or skid off lock body 1;

4. the spoon body 32 of said I shape key 3 is provided with side channel 33, and this side channel 33 has the hypotenuse structure, and is corresponding with the hypotenuse structure of the double wedge 203 of said side control piece 20.

The I shape keyhole 16 at said lock core 15 two ends is secundly slightly all, the tip of pearl 14 and the flange of I shape keyhole 16 are close, the hoodle hole 34 on spoon body 32 two sides of said I shape key 3 is secundly also, make it most advanced and sophisticated corresponding with following pearl 14, this setting, make this type lock have more safety, can prevent non-key operated.

The hoodle hole secundly on spoon body 32 two sides of said key 3, and the hoodle hole is around spoon body axis rotation overlap condition, this just makes when opening the lock with the key, and unblanks also needn't recognize face from any end of lock, has increased safety to owner but does not increase any trouble.

The gradient of quantity, position, width, the degree of depth and the hypotenuse of the side channel 33 of key 3 all can corresponding lock double wedge 203 pairings of side control piece 20 change, to form the lock ﹠ key of diversified pairing, therefore the safety of lock is better.

During use, Fig. 7 and Fig. 8 are that key 3 inserts the state that does not rotate as yet behind the lock core 15 I shape keyholes 16, at this moment, key 3 will descend Zhu14Ding to lock core 15 rotary positions, side channel 33 on 3 spoons of bodies 32 of key is corresponding with the double wedge 203 of side control piece 20, as Figure 11, when screw key 3 drives lock core 15 rotations, in the side channel 33 of the double wedge 203 embedding keys of side control piece 20 (Figure 12), the double wedge 203 of key side channel 33 and side control piece 20 matches can rotational lock core 15, is rotated further key 3, and the circular arc raised line 201 in side control piece 20 outsides leaves the circular arc elongated slot 101 of lock body 1, as shown in figure 10, promptly finished unlocking action, when key 3 goes to original position, side control piece 20 circular arc raised lines 201 align the circular arc elongated slot 101 of lock body 1 again, extract key 3 out, tapered end returns to the blocking before the key turns again.

In sum, it is as follows to conclude characteristics of the present utility model and advantage:

1, because lock core of the present utility model is divided into two sections, at the two ends of lock available same worker's word all The type key unlocking;

2, owing to adopted the control technology of worker's font key and side control piece, the security of lock is better;

3, especially lock worker's font key hole secundly of core, make tip and the worker's font of lower pearl The flange in key hole is close, and can prevent non-key unlocking;

4, the protruding tooth of side control piece has hypotenuse structure and relative with the side channel of the key shank of worker's font key Should, side channel also has the hypotenuse structure, makes when unblanking, and is convenient to plugging together of key, and feel is more suitable, And this kind structure is convenient to processing and manufacturing.
