Problems solved by technology

Existing mechanical locks include a lock case, in which a lock bolt mechanism and a toggle mechanism for toggling the lock bolt mechanism are arranged, a lock bolt hole is opened on the side of the lock case, and the initial state of the mechanical lock is a locked state , at this moment, the locking bolt mechanism protrudes out of the lock housing under the action of the elastic supporting force, and when a pulling force greater than the elastic supporting force is applied to the locking bolt mechanism through the toggle mechanism, the locking bolt mechanism retracts into the locking housing, thereby turning the mechanical After the lock is opened and the toggle mechanism is separated from the lock mechanism, the lock mechanism will extend out of the lock casing under the action of elastic force rebound to lock the mechanical lock; because the lock mechanism can move under a considerable force, when After the mechanical lock locks the door or cabinet, it is only necessary to insert a tool with a certain hardness from the door gap or the cabinet door gap, and apply an axial force towards the lock housing to the lock mechanism, and the lock mechanism is stressed. Move into the lock case to pry the mechanical lock open, and the safety performance of the mechanical lock is low

Embodiment 1

[0025] Embodiment one: if figure 2 As shown, a mechanical lock includes a lock case 1, a lock mechanism 2 and a toggle mechanism for toggling the lock mechanism 2 are arranged in the lock case 1, and a lock hole 111 is opened on the side 11 of the lock case 1. , The lock shell 1 is also provided with a lock bolt retraction blocking mechanism 3 .

[0026] In the specific examples above, such as Figure 5As shown, the lock bolt retraction blocking mechanism 3 includes a power transmission shaft 31, a transmission shaft positioning spring 32, a rotating piece 33, a transmission shaft guide column 35, a first connecting pin 34, a second connecting pin 36 and a rotating piece positioning spring 37, The side of the lock housing 1 is provided with a first shaft hole 112 for the power transmission shaft 31 to extend or retract. The first shaft hole 112 and the lock bolt hole 111 are located on the same side of the lock housing 1. The power transmission shaft 31 is provided with The...

Embodiment 2

[0031] Embodiment two: if image 3 As shown, the difference between this embodiment and Embodiment 1 is only that the structure of the toggle mechanism is different. The toggle mechanism in this embodiment is a lock cylinder device, and the lock cylinder device includes a gourd-shaped lock cylinder axially connected to the lock housing 1 (not shown in the figure), the key (not shown in the figure), the paddle 5 and the L-shaped paddle bracket 6, the structural diagram of the paddle 5 is as follows Figure 6 As shown, the pick bracket 6 is axially connected to the lock housing 1, the first baffle 222 is provided with a gap 2221, the pick 5 has a large end 51 and a small end 52, and the small end 52 of the pick 5 extends into In the gap 2221, the large end 51 of the pick 5 is bent and hung on the pick support 6, the pick 5 is located above the rotating piece 33, and the pick 5 is provided with a positioning hole 53, and the size of the upper end of the positioning hole 53 is lar...

Embodiment 3

[0034] Embodiment 3: The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the toggle mechanism is different. The toggle mechanism in this embodiment includes both the handle device in Embodiment 1 and the lock in Embodiment 2. core device.

[0035] In the above-mentioned first embodiment, second embodiment and third embodiment, a lock bolt positioning mechanism 7 can also be set in the lock housing 1, such as Figure 7 As shown, the lock bolt positioning mechanism 7 includes a base plate 71, a base plate guide post 72, a dial pin 73 and a base plate positioning spring 74. There is a substrate guide groove 711, and the substrate guide column 72 passes through the substrate guide groove 711 and is fixed in the lock housing 1. One side of the rear end of the substrate 71 is provided with a hanging plate 75, the hanging plate 75 is perpendicular to the base plate 71, and the hanging plate 75 There is a pin hole 751 on the upper side, the side 11 of the...

Abstract

The invention discloses a mechanical lock. The mechanical lock comprises a lock shell. A lock bolt mechanism and a shifting mechanism for shifting the lock bolt mechanism are arranged in the lock shell. A lock bolt hole is arranged at the lateral side of the lock shell. A lock bolt retraction baffling mechanism is further arranged in the lock shell. The mechanical lock has the advantages that when a thief stretches a tool with certain hardness from a door gap or a cabinet door gap to apply an axial acting force to the lock bolt mechanism towards the internal side of the lock shell, the lock bolt mechanism cannot move towards the interior of the lock shell under the resistance of a tamper-resistant mechanism, and the mechanical lock cannot be opened, so that the safety of the mechanical lock is improved.

Description

technical field [0001] The present invention relates to a lock, in particular to a mechanical lock. Background technique [0002] Lock is a kind of antitheft tool requisite in people's life, and a lock is adorned on door, cabinet, can prevent thief from entering house and opening cabinet to steal. There are many types of locks, including mechanical locks, electronic locks, mechanical and electronic composite locks, etc. Because mechanical locks are relatively cheap and easy to use, mechanical locks are currently used on doors and cabinets. Existing mechanical locks include a lock case, in which a lock bolt mechanism and a toggle mechanism for toggling the lock bolt mechanism are arranged, a lock bolt hole is opened on the side of the lock case, and the initial state of the mechanical lock is a locked state , at this moment, the locking bolt mechanism protrudes out of the lock housing under the action of the elastic supporting force, and when a pulling force greater than th...
