Abstract

The utility model relates to a door lock with a side channel device. In the utility model, the side edge of the door lock is provided with an upwards-downwards striking gear of a channel switch block, a bolt hitting subassembly is arranged above the striking gear, and the flange of the bolt bumping subassembly tightly supports a clamping tip on the top part of the channel switch block; the clamping tip a is clamped in a concave opening b positioned on a lock bolt. The utility model can make the striking gear separated from a handle of a door, friction among mechanical structures of the components is reduced in the door lock, lesser space is occupied, and the lock body can freely rotate between a locking status and a channel status.

Description

The door lock of lateral channels device

The utility model belongs to the door lock field, specially refers to the lane device that is used for all kinds of door locks.

Existing all kinds of door lock, owing to pursue a kind of tight anti-theft feature, often intension office is complicated, volume is bigger, and all bigger as existing family door lock weight and volume, price is more expensive, lock simple in structure, theftproof is poor again, and it is several simple and crude lock that key can be opened, and in the existing door lock, the striking gear of dead bolt often all is placed on the handgrip of frequent rotation, when rotating handgrip, to cause pivoting friction to the striking gear of dead bolt, same, when stirring the dead bolt device, the handgrip that also must rub, the two all will wear and tear mutually, this just proposed with both function separately, striking gear is not provided with in the position of handgrip, but seek side at door, and both can reduce handgrip and take up space, can alleviate the mechanical wear that they are subjected to again.

The purpose of this utility model is bigger than normal in order to overcome in the existing door latch structure volume weight, defective such as mechanical wear mutually between the parts, and redesign a kind of door lock lateral channels device that reduces friction and reduce the space possessive volume.

The utility model is realized by following technical proposals, a kind of door lock of lateral channels device comprises lock, dead bolt, dead bolt shell, pushes away spring, handle swing arm, it is characterized in that, be provided with the striking gear up and down of a channel switch group at the door lock side, this device top is provided with hits the tongue assembly, is pressing closer the card point a that is arranged on channel switch assembly top by flange, blocks sharp a and is stuck in the recess b that is positioned on the dead bolt, channel switch is dialled upwards, being decided to be has channel status, blocks sharp a dead bolt is blocked, and does not stretch out; Channel switch is dialled downwards, is decided to be no channel status, and the card point breaks away from recess b, and dead bolt stretches out and be that locking states, this device can make lock body change between locking states and channel status, and the swing arm of not overslaugh door handle.

The major advantage of this device is, striking gear and door handle are separated, and makes door lock lower the friction between frame for movement in the parts, and occupies less volume, and lock body is freely rotated between locking states and channel status.

Further specify embodiment below in conjunction with accompanying drawing:

Description of drawings:

Fig. 1 is the structural representation (the passage situation is arranged) of lateral channels device door lock;

Fig. 2 is above-mentioned door latch structure lateral view;

Door lock partial view (no passage situation) when Fig. 3 is pressed for hitting the tongue assembly;

Among the figure, the device of channel switch assembly 1 for stirring up and down, upwards dial to be decided to be channel status is arranged, dead bolt is stuck and can not stretches out, to setting aside, dead bolt just stretches out when door is closed, this is channel-less locking states, the toggle switch up and down of channel switch assembly 1 is connecting 8 and jags that have the sharp a of card that driven by axle of an axle that can rotate around it, what be installed in channel switch assembly top hits tongue assembly 2, produce related motion by withstanding flange with the sharp a of card, hit tongue assembly lower end and linked to each other with dead bolt shell 6 by spring wire L, dead bolt 3 is by the rotation withdrawal of door handle swing arm, and stretch out by the elastic force that pushes away spring 4, whole dead bolt shell 6 is fixed on the doorframe by locking 5, and the door lock compliance of this lateral channels device is very wide, all doors, frame, case, the used mechanical lock of drawer all can use this device.

Claims

1, a kind of door lock of lateral channels device, comprise lock, dead bolt, dead bolt shell, push away spring, handle swing arm, it is characterized in that, be provided with the striking gear up and down of a channel switch group at the door lock side, this device top is provided with hits the tongue assembly, pressing closer the card point a that is arranged on channel switch assembly top by flange, blocking sharp a and be stuck in the recess b that is positioned on the dead bolt.

2, according to the described door lock of claim 1, it is characterized in that, two kinds of location statuss of channel switch are that channel switch is dialled upwards, being decided to be has channel status card point a that dead bolt is blocked, do not stretch out, channel switch is dialled downwards, is decided to be no channel status, the card point breaks away from recess (6), and dead bolt stretches out and is locking states.

According to the described door lock of claim 1, it is characterized in that 3, the toggle switch up and down of channel switch assembly (1) is connecting an axle that can rotate around it (8) and a jag that has the sharp a of card that is driven by axle.
