Description

Targeting settings

Technical field:

The invention relates to the field of lock industry, in particular to an idle lock cylinder.

Background technique:

At present, the mechanical lock cylinders supplied on the market are in two forms: non-idling and idling. A lock factory in Guangdong developed a kind of idling lock cylinder. A few years ago, the idling lock cylinder boom was set off in the lock industry. Law", which causes the deadly defect of the lock key to idle during the use of the idling lock cylinder. In addition, it is difficult to manufacture and requires high precision. Basically, all of them have been withdrawn from the market. In order to make the idling lock cylinder with high safety benefit the society, according to " Orientation law " orientation setting of the present invention eliminates idle lock core. This key also has the fatal flaw of being unable to open the door by idling, so that the idling lock cylinder is vigorously promoted to be used by the society to benefit the society and high security.

Invention content:

The inner lock cylinder assembly is equipped with directional positioning special-shaped pinholes. The two ends of the directional positioning special-shaped pins are semi-circular, and the middle section is cylindrical. The directional positioning special-shaped pins are placed on the inner lock cylinder assembly. Orientation positioning special-shaped pins In the hole, one end of the special-shaped pin is flush with the outer circle of the inner lock cylinder sleeve, and the other end of the semi-circular ball is in the key slot on the inner lock core assembly. Directional positioning holes.

The cross-section of this key is rail-shaped, and the depth and position of the plurality of leaf tooth patterns on the left longitudinal direction of the upper transverse section are the same as the depth and position of the plurality of leaf tooth patterns on the right longitudinal direction of the lower transverse section. The depth and position of the blade teeth are the same as those of the plurality of blade teeth in the longitudinal direction on the left side of the lower cross section. On the corresponding positions of the two longitudinal surfaces of the key, there are semi-spherical concave points for the entry and exit of the semi-spherical ball.

The purpose of directional positioning is to get rid of the fatal defect that the space lock cylinder with high security performance can be opened by idling with the Nakamoto key, so that the idling lock cylinder can be widely used in military, professional, civilian and other fields.

Detailed Description of the Invention: The present invention will be described in detail by sectional drawings below.

Please refer to Figures 1 to 10. Orientation and positioning settings include lock cylinder assembly 1, inner lock cylinder assembly 2, directional positioning special-shaped pin 3, lock case 4, key 5, inner lock cylinder sleeve 6, blade 7, and the front of the semicircular concave point of the key. Flat section 37, lock cylinder assembly 1 is composed of inner lock cylinder assembly 2. lock shell 4, key 5, rear lock cylinder 14, unlocking head 15, clutch plate 16, clutch spring 17, protective cover 18, trapezoidal bump piece 19, the inner lock core frame 20, the rear lock core is provided with a step 21 in the lock housing 4, the rear lock core 14 is placed on the step 21, and the clutch plate 16 is placed in the clutch plate groove 22 of the rear lock core 16, Clutch plate spring 23 is placed in rear lock core 14 spring hole 23, and unlocking head 15 is placed in head hole 24, inner lock core assembly 2 is made of lock core frame 20, plural pairs of blades 7, blade springs 25, trapezoidal convex Point piece 19, interior lock cylinder cover 6, orientation positioning special-shaped marble 3 forms. The lock cylinder frame 20 is cylindrical, and is provided with a plurality of blade placement grooves 27 in the transverse direction, and a plurality of pairs of blades and a plurality of leaf springs are placed in the plurality of blade placement grooves 27, and the lock cylinder frame 20 is provided with a longitudinal key slot 29. There are two trapezoidal protruding pieces 19 placement grooves 27, and the two trapezoidal convex point pieces 19 are placed in the grooves 27, and the inner lock core sleeve 6 is fixed on the outer circle of the lock core frame 20. The inner lock cylinder assembly 2 is provided with a placement hole 11 for directional positioning special-shaped pins. The two ends of the directional positioning special-shaped pins 3 are flat balls 30, and the middle section is cylindrical. The directional positioning special-shaped pins are placed in the placement holes 11. , the inner lock cylinder assembly is placed on the step 26 in the lock housing 4, and the protective cover 51 is placed in the outer end of the lock housing 14.

On the corresponding position on the longitudinal plane of key 5, be provided with hemisphere concave point 31 that hemisphere 30 enters and exits. When the key 5 is inserted into the process in the key slot 29 of the lock cylinder assembly 1, the front flat section 37 on the key 5 will align the semicircular ball 30 on the special-shaped marble 3 in the key slot 29, and advance the lock housing 4 in linkage. In the directional positioning hole 49 that the semi-circular ball 30 enters and exits, the inner lock core assembly 2 is oriented and positioned on the lock housing 4, so that the clutch plate 16 on the rear lock core 14 is accurately aligned with the transverse groove 22 on the inner lock core frame 20 , the key 5 moves forward and reaches the designated position, and the plurality of blade tooth patterns 10 on the key 5 are matched with the plurality of pairs of blades 7, so that the plurality of blade gaps 33 are aligned consistently, the trapezoidal convex point piece 19 moves downward, and the clutch piece 16 on the rear lock core 32 is controlled. The active force of spring 17 pushes in the transverse groove 34 on the interior lock cylinder frame 20, makes rear lock cylinder 32 be connected with interior lock cylinder assembly 2, turns key 5, because the diameter of the directional positioning hole (49) on the lock housing is smaller than the directional positioning The diameter of the hemisphere 30 of the diameter, the hemisphere of directional positioning special-shaped marble enters in the hemisphere concave point 38 on the key, makes the inner lock core 2 separate from the lock housing 4, turns the key 5 to unlock, and in the process of extracting the key 5, The front flat section 37 of the key 5 pushes the directional positioning pin hemisphere 30 into the directional positioning hole 49 on the lock housing 4, and the plurality of blades 7 in the inner lock cylinder frame 20 are moved up and down by the plurality of tooth flowers 10 on the key 5 , so that the notch side 13 on the plurality of blades 7 pushes the slope 44 of the plurality of protrusions on the trapezoidal convex point sheet 19, so that the trapezoidal convex point sheet goes up, and the clutch plate 19 of the inner lock cylinder frame 20 is pushed into the rear lock cylinder 16 , the inner lock core 2 is separated from the rear lock core 16, and the inner lock core is in an idling state.
