Abstract

The utility model relates to a three column type ball shape door lock which consists of an inner ball handle, an outer ball handle, a lock core part, a lock tongue part and a connection part of the inner ball handle and the outer ball handle. The inner ball handle and the outer ball handle are connected through the connection part of the inner ball handle and the outer ball handle; the lock core part is horizontally arranged in the outer ball handle, the connection part of the inner ball handle and the outer ball handle is a rod type structure. A connecting rod type structure is fixedly arranged on the outer ball handle and comprises a transmission rod and a reinforcing rod, the transmission rod is a prism rod, and the reinforcing rod is a columned rod. The utility model can greatly decrease the damage to the structure of the door during the installation of the ball door lock and does not affect the firmness and the safety of the door. In addition, if the structure of the door is slightly damaged during the installation of the three column type ball shape door lock provided by the utility model, the installation of the ball shape door lock can also be more convenient.

Description

The spherical door lock of three pillar type

Technical field

The utility model relates to a kind of at the spherical door lock of pillar.

Background technology

At present, spherical door lock is because of its good looking appearance, easy to use by the generally acceptance of people institute, and spherical door lock is keeping stable sales volume always on the market.Yet, existing spheric door is locked in and also manifests some problems in the long-term use, concrete manifestation is as follows: need open a hole that diameter is about 5 centimetres when spherical door lock is installed on door, it is bigger at first to open the relatively large hole workload of such diameter on door, bring inconvenience to installation, and opening the soundness that has also influenced door behind the hole on the door, and then influenced the security performance of door.

The utility model content

The purpose of this utility model provides the spherical door lock of a kind of three pillar type, makes the installation of spherical door lock more convenient, and can guarantee that the soundness of door is unaffected.

The purpose of this utility model is achieved in that the structure of the spherical door lock of three pillar type is made up of endosphere handle, ectosphere handle, lock core part, dead bolt part and inside and outside ball handle coupling part, inside and outside ball handle links to each other by inside and outside ball handle coupling part, and lock core partly partly links to each other with dead bolt by inside and outside ball handle coupling part; In the lock core preceding door that is loaded on the ectosphere handle partly for sleeping in, inside and outside ball handle coupling part bar type structure.

Described bar type structure is fixedly installed on the ectosphere handle, comprises drive link and bracing piece, and drive link is a square pole, and bracing piece is a cylindrical bar.

Described bracing piece is two altogether, is provided with and the drive link both sides respectively.

By technique scheme as can be seen, the project organization that the utility model adopted significantly reduces the damage of the structure of opposite house in the installation process of spherical door lock, and soundness and safety that the spherical door lock of this structure does not influence door later on are installed on the door.In addition, the less structure of damaging door can also make the installation of spherical door lock more convenient in the installation process of the spherical door lock of three pillar type provided by the utility model.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

The specific embodiment of the present utility model is described below in conjunction with the accompanying drawings: the structure of the spherical door lock of three pillar type is made up of endosphere handle, ectosphere handle 4, lock core part 3, dead bolt part and inside and outside ball handle coupling part, inside and outside ball handle links to each other by inside and outside ball handle coupling part, and lock core part 3 partly links to each other with dead bolt by inside and outside ball handle coupling part; In the lock core part 3 preceding doors 5 that are loaded on the ectosphere handle 4 for sleeping in, inside and outside ball handle coupling part bar type structure; Bar type structure is fixedly installed on the ectosphere handle 4, comprises drive link 1 and bracing piece 2, and drive link 1 is a square pole, and bracing piece 2 is a cylindrical bar; And bracing piece 2 is two altogether, is provided with and drive link 1 both sides respectively.Wherein the endosphere handle is the spheric door lock ball handle that is installed on an inboard, and ectosphere handle 4 is for being installed on the spheric door lock ball handle of outer side of door, and ectosphere handle 4 is provided with key hole, can be by the duty of the spherical door lock of key control gate.

The utility model when mounted, only need to open three apertures and the dead bolt hole perpendicular to aperture gets final product at the door edge side, neither influence the soundness of door, and open three apertures also with respect to opening an easier operation of macropore, end behind the hole dead bolt that three bars on the ectosphere handle is passed in three apertures and the aperture and partly stretch into the inboard of door, in the door inboard endosphere handle is linked to each other with three bars, wherein drive link 1 inserts the core place of endosphere handle, in addition two bracing pieces 2 by screw and the endosphere handle be connected, dead bolt partly is set on the drive link, lock core drives the dead bolt action by prismatic drive link 1, and bracing piece 2 plays the effect of fixing spherical door lock.

Claims

1, the spherical door lock of a kind of three pillar type, its structure is made up of endosphere handle, ectosphere handle, lock core part, dead bolt part and inside and outside ball handle coupling part, inside and outside ball handle links to each other by inside and outside ball handle coupling part, and lock core partly partly links to each other with dead bolt by inside and outside ball handle coupling part; It is characterized in that in the lock core preceding door that is loaded on the ectosphere handle partly for sleeping in inside and outside ball handle coupling part bar type structure.

2, the spherical door lock of three pillar type according to claim 1 is characterized in that described bar type structure is fixedly installed on the ectosphere handle, comprises drive link and bracing piece, and drive link is a square pole, and bracing piece is a cylindrical bar.

3, the spherical door lock of three pillar type according to claim 2 is characterized in that described bracing piece is two altogether, is provided with and the drive link both sides respectively.
