Abstract

A more safe multi-core mechanical safety lock, changes the traditional lock core with a sole lock core into two front-to-back superposed but mutually independent lock core(1) and lock core(7), which are put on a same axes, wherein a key hole(3) of the front lock core and a key hole(6) of the back lock core are mutually stagger-placed. Only if a first lock core(1) is opened, a key can be inserted into the key hole(6) of a second lock core(7) to open a lock head. When the lock is open, at the same time of taking out of the key, the second lock core(7) and the first lock core(1) can be orderly returned by a return spring (5).

Description

Multicore machine insurance lock

Affiliated technical field

The novel machine insurance that relates to use always in the daily life of this practicality is locked the field.

Background technology

The lock core of at present all machine insurance locks all is that single core is fixed, though pattern is had nothing in common with each other, inner core is identical, and the shortcoming of this lock is:

(1) robber makes good use of the shape identical with keyhole that steel is made, and then make the other end

Type utilizes the lever principle can be easily and open tapered end fast.

(2) if the robber bores lock core with electric drill, the speed of then opening tapered end is faster.

Summary of the invention

Purpose is in order to overcome all deficiencies of original machine insurance lock, to make the machine insurance lock really play safety effect.The scheme that its technical problem that solves the utility model adopts is:

The lock core of traditional single core lock is changed to by one forward laps and separate two or more, and make them on same axis, front and back lock core keyhole mutual dislocation.After only opening first lock core, key just can enter the second lock core keyhole, opens tapered end.After opening tapered end, back-moving spring can make second lock core and first lock core reset successively when getting key.

The beneficial effects of the utility model are:

The insurance more of machine insurance lock

Below in conjunction with accompanying drawing the utility model is further specified

The utility model accompanying drawing is the sectional drawing of twin-core machine insurance lock, (multicore machine insurance lock principle is identical therewith), and this figure is divided in two parts.

Description of drawings (numbering consistent) with picture

One, structure:

1. be the first plug body part,

2. be the horizontal lock pin of first lock core

3. be first lock core keyhole,

4. be the vertical lock pin of first lock core

5. be automatic-reset spring

6. be second lock core keyhole

7. be the second plug body part

8. be the second lock core lock pin

9. key

10. tapered end main body

Two, the specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in drawings, twin-core machine insurance lock pin part is by forward lapping and 1. and 7. two separate column type lock cores are formed, front and back lock core is on same axis, 3. and 6. the front and back lock core keyhole is mutual dislocation, the tapered end main body be provided with on 10. with the 4. horizontal lock pin of the vertical lock pin of corresponding first lock core in front and back lock core lock pin position 2. with the second lock core lock pin 8..The vertical lock pin of first lock core 4. with horizontal lock pin 2. in same cross section and at an angle to each other; The horizontal lock pin of first lock core 2. with the second lock core lock pin 8. in same horizontal plane; The vertical lock pin of first lock core 4. with the horizontal lock pin of first lock core 2. in first lock core front portion 1..When key 9. insert first lock core 1. after, 4. the vertical lock pin of first lock core is opened, screw key to the second lock core keyhole 6. with 3. same position of first lock core keyhole, 6. 9. key just can enter the second lock core keyhole, 8. 2. the horizontal lock pin of first lock core this moment opened simultaneously with the second lock core lock pin, continues screw key and open tapered end.After opening tapered end, 5. back-moving spring can make first lock core 1. reset when getting key.Back-moving spring 5. one be fixed on the tapered end main body and 10. go up, the other end is fixed on first plug body and 1. goes up, 5. back-moving spring is positioned at first plug body rear portion 1..The vertical lock pin of first lock core is 4. identical with the 2. pairing key bit of the horizontal lock pin of first lock core.It is identical with the principle of unblanking of common mechanical lock that key is opened the theory of mechanics of lock pin.

Two, effect:

Three,

1, pick-proof, even the robber pries open first lock core, it is very big then to pry open the second lock core difficulty again.

2, anti-drilling, if bore lock core with electric drill, after boring the first cylinder lock pin part, first lock core will rotate with drill bit, make Drill bit can't move on, thereby plays anti-drilling effect.

3, can play the effect of coded lock, because multiple core mechanism safety lock is multicore, so that key can make is knockdown, only The handlebar set of keys is combined together, and just can open safety lock.

Claims (5)

1. 3. and 6. 1. and 7. 1, a kind of multicore machine insurance lock is characterized in that: it is by forward lapping and 1. and 7. two separate column type lock cores combine, and makes front and back lock core on same axis, and the front and back lock core keyhole is mutual dislocation.
2. 2, multicore machine insurance according to claim 1 lock is characterized in that: the vertical lock pin of first lock core that 10. the tapered end main body goes up 4. with horizontal lock pin 2. in same cross section and at an angle to each other.
3. 3, multicore machine insurance according to claim 1 lock is characterized in that: the first lock core lock pin that 10. the tapered end main body goes up 2. and 4. forward, automatic-reset spring is 5. at 1. rear portion of first lock core, and is separately fixed at the tapered end main body and 10. 1. goes up with first lock core.
4. 4, multicore machine insurance according to claim 1 lock is characterized in that: the horizontal lock pin of first lock core that 10. the tapered end main body goes up 2. with the second lock core lock pin 8. in same horizontal plane.
5. 5, multicore machine insurance lock according to claim 1, it is characterized in that: the vertical lock pin of first lock core that 10. the tapered end main body goes up is 4. identical with the 2. pairing key bit of horizontal lock pin.
