Problems solved by technology

[0002]At present, the lock cylinder mechanism of the electronic anti-theft door lock usually uses a connecting rod to drive the anti-locking large square tongue. This transmission method does not move smoothly, and the product mechanism is reliable. The performance is not high; and although some mechanisms use gear transmission to drive the anti-locking large square tongue, the structure is too complicated, the production process is difficult, and it is not convenient to improve the efficiency of mass production

Embodiment 1

[0021] Such as figure 1 As shown, the lock core of the electronic anti-theft door lock includes a lock cover 1 and a lock case 3, the side plate 2 is fixed and installed on the lock case 3 by screws, and the sky and earth rod 4 is slidably set on the rivet post 31 in the lock case 3 , the small square tongue 7 is slidably set on the stud 32 of the lock case 3, and its front end can protrude from the small square tongue hole of the side plate 2, and the anti-lock arm 8 is rotatably set on the lock case 3, and the front end of the anti-lock arm 8 The crank arm is connected with the bayonet position provided on the small square tongue 7. Rotating the anti-lock crank arm 8 can drive the small square tongue 7 to realize anti-lock and open functions by telescopic movement in the small square tongue hole of the side plate 2. The anti-lock crank arm 8 Elastic resetting element torsion spring 11 is arranged on it, and torsion spring 11 one end is sleeved on the rivet column ` of lock h...

Embodiment 2

[0032] Compared with Embodiment 1, this embodiment differs in the structure of the shift fork assembly. Such as image 3 As shown, the shift fork assembly includes an idler shift fork 98, an inner shift fork 93, an outer shift fork 94, a gear plate 92, and a shifting plate 91 are coaxially and rotatably set on the idler shift fork 98, and the idler shift fork 98 An anti-rotation groove 984 is arranged on the wall of the inner hole, a rib 932 matching the anti-rotation groove 984 is arranged on the inner shift fork 93, a limit block 942 is arranged on the outer shift fork 94, and the clutch mechanism includes a clutch driven by a motor. Sheet 16, the clutch pin assembly set on the idle fork, such as Figure 4 As shown, the clutch pin assembly includes a pin hole that radially passes through the idler fork, a shift fork pin 981 arranged in the pin hole, a return spring 983 located in the pin hole and sleeved on the shift fork pin, and a pin hole at the outer end of the pin hole...

Abstract

The invention relates to a lock core for an electronic safe-guard door lock, which comprises a lock cover, a lock shell, a shifting fork component arranged on the lock shell, a large square tongue component, a latch bolt component comprising a latch bolt and a mechanical locking head, wherein the large square tongue component comprises a large square tongue and a toothed crank arm, the large square tongue is arranged on the lock shell in a sliding mode and is provided with a guiding chute, the toothed crank arm is provided with an upright post, a first gear and a shifting block shifted by the mechanical locking head, and the upright post is positioned in the guiding chute; the shifting fork component comprises a switch board, an inner shifting fork, an outer shifting fork, a gear plate and a shifting plate, the gear plate is provided with a second gear meshed with the first gear, one end of the switch board is an end head driven by the mechanical locking head, while the other end is connected with the shifting plate rotatablely, and the shifting plate is provided with a driving part for driving the latch bolt to perform telescopic actions; and a motor component comprises a motor and a clutch mechanism driven by the motor to control the outer shifting fork to rotate. The lock core has the advantages of reliable movement, simple and compact structure, good manufacturability, suitability for mass production, and high safety and reliability.

Description

technical field [0001] The invention relates to a lockset, more specifically, to a lock cylinder of an electronic anti-theft door lock. Background technique [0002] At present, the lock cylinder mechanism of the electronic anti-theft door lock usually uses a connecting rod to drive the anti-locking large tongue. This transmission mode does not move smoothly, and the reliability of the product mechanism is not high; Tongue, but the structure is too complicated, the production process is difficult, and it is not convenient to improve the efficiency of mass production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lock cylinder of an electronic anti-theft door lock with stable transmission, simple and compact structure, favorable mass production, and good reliability and safety. [0004] The technical solution adopted by the present invention to solve the technical problem is: to propose a lock cylinder of an ...
