Abstract

The utility model discloses a linkage mechanism of a bolt for an electronic lock, comprising an oblique bolt 1, an oblique bolt shifting block 2 which is connected with a handle, a shaft 3, a tooth sheet 4, a square bolt shifting block 5 and a square bolt 6; the upper end of the oblique bolt shifting block 2 abuts against a surface 11 of the oblique bolt 1; the oblique bolt shifting block 2 and the tooth sheet 4 rotate around the shaft 3; the tooth sheet 4 is meshed with the square bolt shifting block 5; an A cylinder 51 and a B cylinder 52 are arranged on the square bolt shifting block 5; a C slot 61 and a D slot 62 are arranged at the square bolt 6; the A cylinder 51 and the B cylinder 52 are respectively embedded into the C slot 61 and the D slot 62. The rotation of the oblique bolt shifting block 2 which is connected with the handle drives the linkage of the tooth sheet 4, the square bolt shifting block 5 and the square bolt 6, which leads the protruding and the withdrawing for the square bolt 6 so as to realize the counter locking function of the lock.

Description

The dead bolt link gear

Technical field

The utility model relates to a kind of component of lock, particularly a kind of dead bolt link gear of electronic lock.

Background technology

At present, the dead bolt link gear of the employed electronic lock of people can only the side's of unlatching tongue, does not possess the function of the side's of locking tongue usually.

Summary of the invention

The purpose of this utility model provides a kind of dead bolt link gear of novel electronic door lock, utilizes the rotation of the oblique tongue shifting block that is connected with handle, drive gear piece, the rotation of square tongue shifting block, thereby the side's of promotion tongue is simple in structure, and easy to use, cost of production is low.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of dead bolt link gear of electronic lock, the oblique tongue shifting block 2 that comprises oblique tongue 1, joins with handle, axle 3, gear piece 4, square tongue shifting block 5, square tongue 6; Tiltedly the upper end of tongue shifting block 2 offsets with 11 faces of oblique tongue 1; Tiltedly tongue shifting block 2 rotates around axle 3 with gear piece 4; Gear piece 4 intermeshes with square tongue shifting block 5; Side's tongue shifting block 5 is provided with A cylinder 51 and B cylinder 52, and square tongue 6 is provided with C groove 61 and D groove 62, and A cylinder 51 and B cylinder 52 embed respectively in C groove 61 and the D groove 62.

Owing to adopted said structure, can drive the interlock of gear piece 4, square tongue shifting block 5 and square tongue 6 by the rotation of the oblique tongue shifting block 2 that is connected with handle, the side's of making tongue 6 stretches out or takes in, realization door lock back locking function.

Description of drawings

Fig. 1 is the utility model structural representation;

State when Fig. 2 takes in for square tongue 6;

State when Fig. 3 stretches out for square tongue 6.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

As shown in Figure 2, when oblique tongue shifting block 2 clockwise directions that join with handle rotate, take in oblique tongue 1, stir gear piece 4 simultaneously and rotate,

gear piece

4 and 5 engagements of square tongue shifting block around axle 3 clockwise directions, the side's of making tongue shifting block 5 counterclockwise rotates, B cylinder 52 and A cylinder 51 on side's tongue shifting block 5 move in the D of square tongue 6 groove 62 and C groove 61 respectively, the side's of promotion tongue 6, and the side's of making tongue 6 takes in, untie and lock, tiltedly tongue shifting block 2 and oblique tongue 1 reset to position as shown in Figure 2.

As shown in Figure 3, the oblique tongue shifting block 2 that joins with handle counterclockwise rotates, tiltedly tongue 1 is motionless, stirs gear piece 4 simultaneously and counterclockwise rotates around axle 3,

gear piece

4 and 5 engagements of square tongue shifting block, the side's of making tongue shifting block 5 clockwise directions rotate, B cylinder 52 and A cylinder 51 on side's tongue shifting block 5 move in the D of square tongue 6 groove 62 and C groove 61 respectively, the side's of promotion tongue 6, and the side's of making tongue 6 stretches out, door is locked, and tiltedly tongue shifting block 2 resets to position as shown in Figure 3.

Claims

1. the dead bolt link gear of an electronic lock is characterized in that: the oblique tongue shifting block (2), axle (3), gear piece (4), square tongue shifting block (5), the square tongue (6) that comprise oblique tongue (1), join with handle; Tiltedly the upper end of tongue shifting block (2) offsets with (11) face of oblique tongue (1); Tiltedly tongue shifting block (2) rotates around axle (3) with gear piece (4); Gear piece (4) intermeshes with square tongue shifting block (5); Side's tongue shifting block (5) is provided with A cylinder (51) and B cylinder (52), and square tongue (6) is provided with C groove (61) and D groove (62), and A cylinder (51) and B cylinder (52) embed respectively in C groove (61) and the D groove (62).
