Embodiment 1

[0018] See figure 1 , 2 The transmission mechanism of the deadbolt provided by the present invention includes a driving gear 201 fixed on the power output shaft 202 of the motor assembly 2 and a driven gear 7 that drives the movement of the deadbolt 6, and the driving gear 201 passes through the swing arm gear assembly 3 Connected with the driven gear 7; the swing arm gear assembly 3 includes a swing arm 301 and a swing arm gear 302, one end of the swing arm 301 is movably mounted on the power output shaft 202, and the other end of the swing arm 301 is movable There is a swing arm gear 302 meshing with the driving gear 201 and the driven gear 7 at the same time. The motor assembly 2, the dead bolt 6 and the driven gear 7 are all installed on the lock body 1, and the driven gear 7 is provided with a toggle block 701 to cooperate with 2 bayonet sockets 601, 602 on the dead bolt 6; Gear 7 can also be driven by mechanical lock 5, and mechanical lock 5 comprises lock tube 501, is...

Embodiment 2

[0026] See Figure 4 , this embodiment is based on Embodiment 1, the swing arm gear assembly 3 and the driven gear 7 are connected through a bridge gear assembly 8 .

[0027] The bridge gear assembly 8 includes a fixed shaft 801, a first bridge gear 803 and a second bridge gear 802 fixed at both ends of the fixed shaft 801, and the first bridge gear 803 and the second bridge gear 802 are respectively connected to The swing arm gear 302 in the swing arm gear assembly 3 meshes with the driven gear 7 .

Abstract

The invention discloses a transmission mechanism of a spring bolt. The transmission mechanism comprises a driving gear fixedly arranged on a power output shaft of a motor assembly and a driven gear driving the spring bolt to move. The driving gear is connected with the driven gear through a swing arm gear assembly. The transmission mechanism has the advantages that the motor assembly and the driven gear driving the spring bolt to move are connected through the swing arm gear assembly, when the motor assembly is started, large acting force can be output through the swing arm gear assembly to drive the driven gear to rotate, resistance during locking or unlocking can be overcome, the phenomenon of jamming is not prone to happening, few failures are generated, work is reliable, and the service life of a lock can be prolonged; and due to the fact that the swing arm gear assembly is movably fixed to the power output shaft of the motor assembly, when a key is used for emergency unlocking, rotation of the driven gear cannot be hindered by the swing arm gear assembly, and it is ensured that emergency unlocking has no failure.

Description

technical field [0001] The invention belongs to a lockset, in particular to a transmission mechanism of a lock tongue. Background technique [0002] The automatic lock body on the market at present all is to cooperate with the driven gear that drives dead bolt motion by micro-motor assembly through transmission mechanism, realizes unblanking and locking under normal circumstances. The main problem that this structure exists is that the gear of the transmission mechanism is directly meshed with the driven gear, no matter whether the locking or unlocking resistance is relatively large, it is prone to jamming, which affects the service life of the lock. Contents of the invention [0003] The purpose of the present invention is to provide a transmission mechanism for the deadbolt with few faults and reliable operation in view of the defects of the prior art. [0004] The technical scheme that realizes the object of the present invention adopts is as follows: [0005] The tra...
