Abstract

The utility model discloses a novel three-bar door lock, including front handle, C piece, rotary switch, lock protecgulum, reset torsion spring, flat chi, side pipe and jump ring, the C piece is located the installation end of front handle, one side of rotary switch is the perk form setting, the lock protecgulum rotates with front handle through rotary switch and installs, the installation end of flat chi and the fixed mounting of unblanking of front handle, the torsional spring that resets suit corresponds the installation in the outside of flat chi and lock protecgulum inboard; the outside of flat chi is equipped with the arch, the installation end of square pipe corresponds the rotary switch and is equipped with the rotor plate, and the installation end of square pipe passes through little spring and protruding cooperation and flat chi elastic mounting. This novel three-bar door lock through the rotating switch cooperation tool to lock equipment of perk structure, need not to use friction pad, effectively avoids the risk of the dead lock of card to improve the tool to lock cooperation door body installation scope through long banding flat chi, the simple installation can not appear the advantage of kayser during the use.

Description

Novel three-bar type door lock

Technical Field

The utility model relates to a lock technical field specifically is a novel three-bar type lock.

Background

Three pole locks are applied to indoor tool to lock more, when three pole locks are installed and use, when needing the rotation switch cooperation to open the tool to lock, the rotation switch that three pole locks used on the market adopts a planar iron plate structure setting more, the dead problem of card easily appears when using, adopt the installation through the supplementary iron sheet of friction gasket for avoiding this problem, and the friction gasket very easily damaged leads to the lock to be unable to open, and the flat chi that three pole locks cooperation was used on the market adopts the cross shape to set up, it leads to the lock to open to clamp the locking closure easily, the use of giving the user brings inconvenience.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel three-bar lock, rotating switch cooperation tool to lock equipment through the perk structure, need not to use the friction gasket, effectively avoid the risk of the dead lock of card, and improve tool to lock cooperation door body installation scope through long banding flat chi, simple installation, the advantage of kayser can not appear during the use, the rotary switch that has solved three-bar lock and use on the market adopts a planar iron plate structure setting more, the dead problem of card easily appears when using, adopt the installation through the supplementary iron sheet of friction gasket for avoiding this problem, and the friction gasket is very easily damaged and leads to the lock to be unable to open, and the flat chi that three-bar lock cooperation was used on the market adopts the cross shape to set up, clamp the locking closure easily and lead to the lock unable opening, the problem of inconvenience is brought in the use of giving the user.

In order to achieve the above object, the utility model provides a following technical scheme: a novel three-rod type door lock comprises a front handle, a C piece, a rotary switch, a lock front cover, a reset torsion spring, a flat ruler, a square tube and a clamp spring, wherein the C piece is arranged at the mounting end of the front handle, one side of the rotary switch is arranged in a tilting shape, the lock front cover is rotatably mounted with the front handle through the rotary switch, the mounting end of the flat ruler is fixedly mounted with the unlocking end of the front handle, and the reset torsion spring is sleeved outside the flat ruler and correspondingly mounted with the inner side of the lock front cover;

the outside of flat chi is equipped with the arch, the installation end of square pipe corresponds the rotary switch and is equipped with the rotor plate, and the installation end of square pipe passes through little spring and protruding cooperation and flat chi elastic mounting, the outside and the rotor plate cooperation that the jump ring corresponds square pipe are connected.

Furthermore, the C piece and the rotary switch are correspondingly arranged inside the front handle.

Furthermore, the lock front cover is provided with a notch corresponding to the reset end of the reset torsion spring, and a limit plate is arranged corresponding to the notch.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses a tumbler cooperation rotor plate of perk structure need not to use friction pad piece to the locking tool equipment, effectively avoids the risk of the dead lock of card, and long banding flat chi cooperation is through little spring installation side pipe, improves the locking tool cooperation door body installation scope, and the kayser can not appear during the use, improves user's result of use simple to handle.
