Detailed Description

The present application will be described in further detail below with reference to the accompanying drawings.

As shown in the drawings, the right-hand setting of the blade bolt type mechanical lock cylinder 2 of the present application can apply the prior art, that is, it is not described again.

As shown in fig. 1 and 2, a mechanical lock with a bolt type blade at least comprises a lock head 1 and a lock cylinder 2, and is characterized in that: the blade bolt 3 is continuously arranged in 30 single layers shown in the embodiment (a wide L-shaped or T-shaped groove with the same depth as the poking protrusion 3a is arranged above the hole arranged on the lock core 2 or the innermost side of the hole, so that the blade 3 is arranged, after all the blades are arranged, the same L-shaped or T-shaped body is inserted into the groove, the drawing is omitted), a hole is arranged on the lock core 2, the lock head 1 is provided with corresponding holes which respectively correspond to the two sides of the blade bolt 3, the two sides of the blade bolt 3 can be connected with the corresponding holes of the lock head 1, and the opening is realized when the two sides of the blade bolt 3 are just separated from the lock head 1; the blade bolt 3 is in a shape of a circular truncated cone cross section and is provided with no key hole, the left and right sides of a symmetrical point below the blade bolt 3 are provided with poking protrusions 3a, and two sides of the root of the poking protrusions 3a are provided with (or the left and right ends above the lock cylinder lock hole 2a are provided with) convex blocks 3c to ensure that the poking protrusions 3a can smoothly enter the key bit.

The upper (or simultaneously lower) end face of each blade bolt 3 is provided with a sawtooth shape 3b, the left and right (end faces of the ends) can be alternately arranged with slight height difference and relative irregularity, and the possibility of technical opening of the knob lock core can be resisted.

Referring to fig. 3, the blade bolt 3 can be correspondingly arranged in a double-layer mirror image corresponding to the lock cylinder lock hole 2a, which is not shown.

Referring to fig. 4, the blade is tied with a key 4 corresponding to the poking protrusion 3a, the main body of the key 4 is a cuboid, the front end groove of the key is opened and is in convergence connection with a snake-shaped groove, and the snake-shaped groove takes the end surfaces at two sides as teeth and is correspondingly connected with the left side and the right side of the poking protrusion 3 a; the double-layer mirror image is correspondingly arranged, and the keys are the double-sided tooth patterns which respectively correspond to the double-layer mirror image.

Compared with the prior art, the beneficial effect of this application lies in:

the structure of the blade bolt is simplified and a large number of the blade bolts are arranged continuously, the upper end face or the lower end face of each blade bolt is provided with a sawtooth shape, the left end face and the right end face (the end faces of the two ends) can be arranged alternately in a slightly-stepped and irregular mode, the detection is difficult to achieve in any technical mode, all the blade bolts are uncertain, and the possibility of technical opening can be basically eliminated.

Compared with the prior mechanical blade bolt locking technology: the key hole is not arranged below the blade bolt, namely, legs supported by the left side and the right side are not arranged, the damage to the opening property of the blade bolt from the inside of the lock hole is not feasible, the blade bolt is small and solid, the lock hole or the arrangement hole of the lock cylinder is smaller, the structure is simplified, the manufacture is easier, the design of the key is more attractive and has high practicability, restriction factors at two ends of the blade bolt key hole are not included, and the operation distance of the blade bolt can be designed simply and excellently.

For example, the blade bolt can be arranged in a way that the supporting width of the blade bolt is not less than 0.5mm above the lock hole of the lock cylinder, and the possible distance is as follows:

the diameter of the lock core is 13mm, the left and right lengths of the blade bolt can be 10mm, the left and right lengths of the lock hole of the lock core are 6mm, the width of the poking protrusion of the blade bolt is 1.6mm, the width of the key body is about 6mm (the two sides of the key are narrowest and 0.7 mm), and the running distance of the key body can stably reach 3 mm.

In the blade bolt in the continuous arrangement, if the key arrangement of each blade bolt is only left, middle and right, and the equal distance selection is adopted, and 28 blade bolts are arranged, the change (28 power of 3) of the key is 2287677.92454961 hundred million (the key amount) possibly, and the 3mm distance provides more "random" space |, so that the security and reliability of the key are greatly improved.

Meanwhile, the pore channel of the lock hole of the three-end-face lock cylinder is firm and reliable, the left and right maximum lengths of the lock hole of the lock cylinder can be only 6mm, and the operability of technical opening is greatly reduced.

To sum up, the present application provides a simpler construction, longer travel distances, larger and more secure key amounts, and less detectibility, with qualitative leaps in performance, extreme reliability and safety, and, as it were, substantially eliminating the possibility of technical opening.
