Description

A kind of super many groups of pellets shot from a slingshot are the cylinder lock of keyhole fixedly

One, technical field:

The utility model relates to a kind of lock, particularly cylinder lock.

Two, background technology:

Present cylinder lock, though of a great variety, its structure is basic identical, has some shortcoming: 1, the limited amount of pellet shot from a slingshot group, the permutation and combination kind of existence are also few, ordinary people's GPRS its Changing Pattern, as long as there is time enough just can open a lock; 2, only exist a pellet shot from a slingshot to tack face between the lock core of present lock and the lock body, become and formed the possibility of unblanking that with master key whole pellets shot from a slingshot to be extruded lock core; 3, present lock also uses the method for looking for " small stair " to open easily; 4, lockhole is easy to be stopped up by object, the phenomenon of dialling not come out occurs.

Three, summary of the invention:

The utility model purpose is to provide a kind of limited amount that can solve the pellet shot from a slingshot group, can prevent with master key or " small stair " technology of looking for is unblanked, the mechanical anti-theft lock that has only corresponding specific key to open.

The technical solution of the utility model comprises: by lock body, keyhole, internal cylinder, the internal cylinder back-moving spring, pellet shot from a slingshot, pellet shot from a slingshot hole spring, key, the tongue switching bar, dead bolt rod lock ring plate is formed, keyhole and lock body are one, internal cylinder is embedded in the lock body, between internal cylinder and the keyhole certain distance is arranged, mid portion is a lock body, bearing unit is arranged on the internal cylinder, the internal cylinder other end has the internal cylinder back-moving spring, has multiple row pellet shot from a slingshot hole group on the internal cylinder, 4 pellets shot from a slingshot and a pellet shot from a slingshot hole spring are arranged in each pellet shot from a slingshot hole, two pellet shot from a slingshot bolt faces are arranged between internal cylinder and the lock body, multiple row tooth road is arranged on the key piece, dead bolt rod lock ring plate is enclosed within on the tongue switching bar.

The advantage that the utlity model has: 1, solve the very few problem of pellet shot from a slingshot group number, has multiple row pellet shot from a slingshot hole group on the internal cylinder, or the parallel a plurality of internal cylinder of use, make pellet shot from a slingshot group number be increased to thousands of groups (specifically organizing number can follow according to the needs decision) like this by several groups, the row tooth row number of key or the sheet number of key also roll up, and solved very few and the problem that quilt cover is opened of pellet shot from a slingshot group number.2, in the same pellet shot from a slingshot hole 4 pellets shot from a slingshot are arranged, be respectively first pellet shot from a slingshot, second pellet shot from a slingshot, the 3rd pellet shot from a slingshot, the 4th pellet shot from a slingshot, spring, the length of second and third pellet shot from a slingshot and the thickness that equals internal cylinder, when lock-out state, wherein have at least in the pellet shot from a slingshot hole of part between internal cylinder and keyhole of first and second pellet shot from a slingshot in the part pellet shot from a slingshot hole and the 3rd pellet shot from a slingshot, so just solved " looking for small stair " method and technology and unblanked.Equally, because two pellet shot from a slingshot bolt faces are arranged between internal cylinder and lock body, it is impossible to use unlocked by universal key to become.3, the keyhole back is not because there is dead bolt to block, and therefore the object of filling in the keyhole can be extruded keyhole.

Five, the specific embodiment:

The utility model is described in further detail with the specific embodiment with reference to the accompanying drawings below:

From Fig. 1-6 as can be known, the utility model is by lock body 1, keyhole 2, internal cylinder 3, pellet shot from a slingshot 6, pellet shot from a slingshot hole spring 7, key, tongue switching bar 4, dead bolt rod lock ring plate 5 is formed, keyhole 2 and lock body 1 are one, internal cylinder 3 is embedded in the lock body 1, between internal cylinder 3 and the keyhole 2 certain distance is arranged, mid portion is a lock body 1, on the internal cylinder 3 bearing unit is arranged, make the internal cylinder can only be towards front and back or move left and right, the internal cylinder other end has internal cylinder back-moving spring 8, has multiple row pellet shot from a slingshot hole group on the internal cylinder 3, or using a plurality of parallel internal cylinder, the columns of pellet shot from a slingshot hole group can be 1 row on the internal cylinder, 2 row, 3 row, to infinite row, concrete columns can be set according to actual needs.4 pellets shot from a slingshot 6 and a pellet shot from a slingshot hole spring 7 are arranged in each above-mentioned pellet shot from a slingshot hole, two pellet shot from a slingshot bolt faces are arranged between internal cylinder and the lock body, multiple row tooth road is arranged on the key piece, or use multi-disc key, it is identical with the columns of the pellet shot from a slingshot hole group of internal cylinder that denture on the key piece is always arranged number, and the shape of key shape and keyhole adapts; Dead bolt rod lock ring plate is enclosed within on the tongue switching bar, on the dead bolt rod lock ring plate blunt v notch v is arranged, breach on the dead bolt rod lock ring plate aligns with the breach of internal cylinder, and dead bolt rod lock ring plate and tongue switching pole pair answer the position that screw is arranged, and uses screw rod that they are fixed together.As shown in Figure 2: when dead bolt rod lock ring plate is rotated, promote internal cylinder and move backward, get through the passage of dead bolt rod lock ring plate, lock just can be opened.

Fig. 7,8,9, the 10th, the unidirectional lockhole figure that the utility model is different, the pellet shot from a slingshot group number that they use is respectively: Fig. 7 is 10 groups of pellets shot from a slingshot, and Fig. 8 is 15 groups of pellets shot from a slingshot, and Fig. 9 is 20 groups of pellets shot from a slingshot, and Figure 10 is 25 groups of pellets shot from a slingshot.

Figure 11,12,13, the 14th, the reversible lock hole pattern that the utility model is different uses this lockhole pellet shot from a slingshot group number to be multiplied.As Figure 11 20 groups of pellets shot from a slingshot can be arranged, Figure 12 can have 30 groups, and Figure 13 can have 40 groups, and Figure 14 can have 50 groups.

Open theory of the present utility model is: insert corresponding key, turning handle, the tongue switching bar rotates, dead bolt rod lock ring plate is rotated simultaneously, promoting internal cylinder when ring plate is rotated is subjected to displacement, the displacement of lock core is rotated dead bolt rod lock ring plate and is not obstructed, thus the rotation of tongue switching bar be not obstructed yet, lock can be opened.

Locking principle of the present utility model: do not insert key, the twisting handle, dead bolt rod lock ring plate produces thrust to internal cylinder, because of internal cylinder has been tacked by the pellet shot from a slingshot in the pellet shot from a slingshot hole, and can not be subjected to displacement, so the rotation path of dead bolt rod lock ring plate is not got through, limited the rotation of dead bolt rod lock ring plate like this, dead bolt rod lock ring plate limits the rotation of tongue switching bar again, can not open thereby be directed at lock.
