Abstract

The invention relates to a theftproof lock core with five rows of three-dimensional criss-cross cylindrical pins, comprising a lock body, a lock core, cylindrical pins and a key. Different from a common lock, the same lock core is simultaneously provided with transverse cylindrical pins and longitudinal cylindrical pins, i.e. an upper right longitudinal cylindrical pin (2), an upper left longitudinal cylindrical pin (15), a lower right longitudinal cylindrical pin (14) and a lower left longitudinal cylindrical pin (16) form the longitudinal cylindrical pins. An upper transverse cylindrical pin (10) and a lower transverse cylindrical pin (11) form the transverse cylindrical pins. In the theftproof lock core with five rows of three-dimensional criss-cross cylindrical pins, including four rows of longitudinal cylindrical pins and one row of transverse cylindrical pins, thus the safety of the key is greatly improved and the situation that the instant opening caused by the resonance of the cylindrical pins cannot happen. Meanwhile, the technical opening difficulty can be improved and the safety and the reliability of theftproof door locks can be ensured.

Description

Anti-theft lock with five rows of three-dimensional criss-cross cylindrical pins

Technical field

The present invention relates to antitheft door lock core, be specifically related to a kind of anti-theft lock, belong to International Classification E05B27/00 " the cylinder lock technical field that has tumbler pin or pellet shot from a slingshot " with five rows of three-dimensional criss-cross cylindrical pins.

Background technology

The marble row numbers of at present traditional mechanical anti-theft lock lock core mostly is 1-3 row, and is single direction.Because many security doors factory uses lockset progressively to adopt " Europe superscript ", pellet shot from a slingshot difference will make greater than 2. because the not high traditional cylinder lock of the few and theoretical secret key amount of marble row numbers, actual secret key amount does not reach " Europe superscript " requirement far away, and pellet shot from a slingshot is that single direction is easily by vibration lockaid gun and unlocked by universal key.

Summary of the invention

The objective of the invention is to overcome above-mentioned deficiency, and a kind of five row's marble theft-proof lock pins vertical, horizontal, the both direction design that adopt are provided.

Technical solution of the present invention is as follows: a kind of anti-theft lock with five rows of three-dimensional criss-cross cylindrical pins, comprise lock body 1, go up right vertically pellet shot from a slingshot 2, spring 3, lock core 4, locking face 9, transversely pellet shot from a slingshot 10, laterally descend pellet shot from a slingshot 11, spring 12, go up the vertical pellet shot from a slingshot 15 in a left side, the vertical pellet shot from a slingshot 14 of bottom right, the vertical pellet shot from a slingshot 16 of bottom left.

The present invention has adopted a last left side, upward the right side, bottom left, bottom right four are arranged vertical pellet shot from a slingshot, the bottom has adopted a horizontal row to pellet shot from a slingshot, make the time with the vibration lockaid gun, can not make pellet shot from a slingshot resonance take place and the situation of moment unlatching, simultaneously can not insert two kinds of master keys simultaneously in little lock chamber and carry out technical opening, and the safety that has guaranteed security door is with reliable.

The specific embodiment

Below in conjunction with accompanying drawing and example the present invention is further described.

Be illustrated in figure 1 as right vertically pellet shot from a slingshot 2, and go up the working condition schematic diagram of horizontal pellet shot from a slingshot, following horizontal pellet shot from a slingshot.

Be illustrated in figure 2 as a left side vertically pellet shot from a slingshot 15, go up right vertically pellet shot from a slingshot 2, the vertical pellet shot from a slingshot 16 of bottom left, the vertical pellet shot from a slingshot 14 of bottom right and transversely pellet shot from a slingshot 10, laterally descend the working condition schematic diagram of pellet shot from a slingshot 11.

Comprehensively illustrated in figures 1 and 2, for whole pellets shot from a slingshot firmly combines lock core and lock body, it can not be rotated mutually, and reach the locking purpose.

Fig. 3 is the vertical view of key.

Fig. 4 is the upward view of key.

Any a, b among change Fig. 3 and Fig. 4, c, d length is the secret key amount of lock core for a change.

Shown in Figure 5, rivet 17 is integral locking face 9 and lock core 4 rivetings.Open the work schematic diagram of lock core as Fig. 5, when Figure 6 shows that the insertion key.

When inserting key, because five semicircle steps are arranged on the key, wherein the middle part is used for the location.Top left part and above right part, following left part and below the semicircle step of right part, will go up right vertically pellet shot from a slingshot 2, go up a left side vertically pellet shot from a slingshot 15, the vertical pellet shot from a slingshot 14 of bottom right, the vertical pellet shot from a slingshot 16 of bottom left push in lock body 1 annular groove, this moment, lock core can arbitrarily rotate.Shown in Fig. 6 C-C section, Fig. 6 C-C section has provided the vertical pellet shot from a slingshot 2 in the last right side and the vertical pellet shot from a slingshot 16 of bottom left enters lock body 1 annular groove schematic diagram.In like manner go up vertical pellet shot from a slingshot 15 in a left side and the vertical pellet shot from a slingshot 14 of bottom right and can enter annular groove.

When key inserted, because key 18 is provided with the depth and does not wait alveole, when all horizontal pellets shot from a slingshot entered alveole, transversely pellet shot from a slingshot 10 and horizontal pellet shot from a slingshot 11 down just in time were in lock body 1 and lock core 4 cylindrical endoporus junctions, and then lock core can rotate, and is opening.
