The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

Shown in Figure 1, be the main TV structure schematic diagram that the present invention locks.In the drawings, lock 3 comprises housing 2, stretches out the locking bar 1 of outside from housing 2 left sides and is located at the rectangle key hole 4 of front bottom righthand side.Wherein, housing 2 is generally the metal material making; Key hole 4 over against shell in the back be provided with key positioning shaft hole 5, with and the electronic alarm Alarm contactor 6 on next door.

Shown in Figure 2, be the sectional structure schematic diagram of Fig. 1.By among the figure as can be known, in housing 2, be provided with the bearing support 8 of a L-square, be fixedly connected with a riser 9 above the bearing support 8 at this.The corresponding hole 10 of can horizontal anomalous movement passing locking bar 1 that is provided with is fixed with spacing card 16 on the left end of shell 2 inside lock lever 1 on riser 9 and housing 2.Spacing card 16 right sides are with recovery spring 7 to the locking bar 1 of riser 9, after the locking bar 1 stressed power that moves right is disappeared, recover spring 7 locking bar 1 is set back.The right-hand member 11 of locking bar 1 for the right angle and under stretch, also be right angle end 11, the minimum point that this right angle end is stretched for 11 times be higher than bearing support 8 above.In conjunction with Fig. 3, on the right-hand member 11 corresponding bearing supports 8 of riser 9 right sides and locking bar 1, be provided with and the key tooth stretched stir the teeth groove 12 of right angle end 11 move left and right.Be fixed with electronic alarm 15 on below in housing 2, this alarm 15 alarm switches one contact 14 is connected with metal shell 2, and it is other that another contact 6 is arranged on key positioning shaft hole 5 by line 13.Alarm contactor 6 and key positioning shaft hole 5 be located at straight right inboards, housing 2 back, key hole 4 on.If not this key when unblanking, is inserted into key hole 4 and can contacts Alarm contactor 6 and housing 2 simultaneously.Key all is a metal generally, contacts Alarm contactor 6 and housing 2 is equivalent to connect alarm switch, makes electronic alarm 15 send chimes of doom.Certainly, electronic alarm 15 can also be located in the put space that constitutes in the lock rear casing.Electronic alarm 15 is prior art and product, and volume is very little, on sale on the market.As electronic door bell, motorcycle and car electronic alarm etc.From Fig. 2 and Fig. 3, also can find out, if many locking bars 1 are set, can be not in one plane between them.

Shown in Figure 4, be the structural representation of key of the present invention.This key 21 is connected with one section secondary spoon axle 19 to 17 fixedly connected spoon axles 22, inner spaced and parallel by the outer end with spoon and the tooth 18 that pulls out that is connected with secondary spoon 19 vertical fixing constitutes.Wherein, the inner termination 20 of spoon axle 22 is corresponding with described key positioning shaft hole 5, after inner termination 20 is inserted key positioning shaft hole 5, key 21 is rotated smoothly, the tooth 18 that pulls out of key will be through the teeth groove 12 of bearing support 8 right-hand members in clockwise rotation, just can stir the right angle end 11 of locking bar 1, locking bar 1 is moved right, stretch out in the outer locking bar left end head of left side shell and contract.So, the width of teeth groove 12 and pull out the size of tooth 18 and length also is to be provided with not repeat to lock and the essential condition of key.

The present invention lock 3 and the operating principle of key 21 be:

Key 21 is inserted in the key hole 4 of lock 3, the inner termination 20 of spoon axle 22 also is inserted in the key positioning shaft hole 5, clockwise rotate key 21, the tooth 18 that pulls out of key 21 passes teeth groove 12, stir the right angle end 11 of locking bar 1, locking bar 1 is moved right, stretch out in the outer locking bar 1 left end head of left side shell and contract, this process is for unblanking.Key 21 is taken out, and locking bar 1 restores to the original state under the effect that recovers spring 7, and locking bar 1 left end head is stretched out outside the shell of left side, and this process is for locking.

From Fig. 2, Fig. 3 and Fig. 4 as can be seen, locking bar 1 can be provided with one or many, with and being equipped with of the right angle end length of stretching for 11 times and key 21 number of teeth of pulling out tooth 18 and height, also have the width of teeth groove 12 and pull out the size of tooth 18 and the wide and thick setting of length, key positioning shaft hole 5 and spoon axle inner termination 20 and key axis hole 4, can design countless unduplicated locks and key thereof.If disorderly open with unmatched key, can touch Alarm contactor 6 and make electronic alarm 15 send chimes of doom.

Shown in Figure 5, be the structural representation that the present invention constitutes lock.Among the figure,, added the positioning chamber 25 of circular arc inserted link 29 at the two ends of lock body 2 respectively and inserted chamber 26 based on the lock of above-mentioned Fig. 1～4.Wherein, the top of positioning chamber 25 and right side are provided with the side channel 24 that can make inserted link 29 lateral rotation, and the right-hand member of inserted link 29 connects with cavity 25 geocoded activities by bearing pin 23, and inserted link 29 can rotate flexibly around bearing pin 23.Be provided with jack 28 above the insertion chamber 26, the moved end of inserted link 29 can be inserted in the chamber.On the inboard of inserted link 29 moved end heads, be provided with and locking bar 1 quantity and corresponding jack or the groove 27 of size, the outer spigot of locking bar 1 can insert in this jack or the groove 27 and locking.The spoon that the people arrests key 21 inserts 17 in the lock from key hole 4, clockwise rotates, and stirs locking bar 1 and moves to right, and receives in the left end head, and inserted link 29 moved end heads can be transferred to, and unblank.The lock of this structure can be used for locking wheel, door latch and cabinet snap close etc. by inserted link 29.

Shown in Figure 6, be the structural representation that the present invention constitutes door lock.In the drawings, lock 3 is fixedly connected with the inboard of door-plate 33, and the keyhole that key 21 is provided with by door-plate 33 inserts in the key hole 4, rotates spoon and stirs 17 in the left end head of locking bar 1 and receive, and makes it to leave to be located at jack 32 corresponding on the doorframe 31, and realization is unblanked to open the door.The lock of this structure does not need to change, and the lock of directly using above-mentioned Fig. 1～4 gets final product.Simple in structure, easy to use.
