Description
Technical Field
The utility model belongs to the technical field of door locks, and particularly relates to a door lock head.
Background
When the door lock is installed on site, due to the fact that the thickness of various door plates is different, some door plates are thick, some door plates are thin, therefore, the connection distance between the door lock handles on two sides is easy to be too long or too short, the distance between the door lock handles on two sides is generally fixed, adjustment cannot be conducted, when the distance between the fixing column of the door lock handle on one side and the connection hole of the door lock handle on the other side is too short, the installation problem can be solved by penetrating through long screws, but due to the fact that the distance between the connection positions is provided, the situation that the door lock swings due to loosening of connection easily occurs after the use time is long, the service life of the door lock is short, when the distance is too long, installation connection cannot be conducted between the door lock handles on two sides, and the on-site installation is inconvenient, and the main defects of the prior art are overcome.
Disclosure of Invention
Aiming at the problems in the background art, the utility model aims to provide a door lock head which can adjust the connection distance, is more firm and stable in connection, has long service life and is convenient for field installation so as to solve the problems.
In order to achieve the above purpose, the present utility model provides the technical scheme: the utility model provides a lock tapered end, its includes tapered end body and a plurality of connecting rod, and this tapered end body both sides fixedly connected with fixed column, this connecting rod one end fixedly connected with spliced pole, the fixed slot has been seted up to this fixed column inboard, and this spliced pole penetrates threaded connection in this fixed slot, makes this connecting rod detachable fixed connection in this fixed column top.
The utility model has the following advantages: the connecting rod can be detached and fixedly connected above the fixed column, so that the connection distance between two sides is adjusted, overlong or too short conditions are prevented, the connection is firmer and more stable, the service life of the door lock is prolonged, and the door lock is convenient to install on site.

Detailed Description
As shown in fig. 1 to 4, a door lock head comprises a head body 10 and a plurality of connecting rods 20, wherein the plurality of connecting rods 20 are detachably connected to one end of the head body 10, and when in use, the head body 10 is mounted on a door lock for a user to insert a key to open and close the door lock.
The two sides of the lock head body 10 are respectively provided with a fixed column 11, the fixed columns 11 are fixedly connected to the two sides of the lock head body 10, the inner side of each fixed column 11 is provided with a fixed groove 111, the inner side wall of the top of each fixed groove 111 is provided with a fixed thread 112, and when in use, the fixed threads 112 are used for being matched and connected with the connecting rod 20.
One end of the connecting rod 20 is provided with a connecting column 21, the connecting column 21 is fixedly connected to one end of the connecting rod 20, the diameter of the connecting rod 20 is larger than that of the fixing groove 111, the diameter of the connecting column 21 is smaller than that of the fixing groove 111, the surface of the connecting column 21 is provided with a connecting thread 211, and the connecting thread 211 is matched with the fixing thread 112.
In practical implementation, the connecting screw thread 211 of the connecting post 21 is matched with the fixing screw thread 112 of the fixing groove 111 to be fixedly connected, so that the connecting rod 20 can be detachably and fixedly connected above the fixing post 11, and the installation is simple and convenient.
The connecting rod 20 is provided with a connecting groove 22 on the inner side, and a fixing thread 221 is provided on the inner side wall of the top of the connecting groove 22, and the fixing thread 221 is used for being connected and fixed with a screw in a matching manner when in use.
When the door lock is used, when the door lock handles are respectively arranged on two sides of the door plate, the connection distance between the door lock handles on two sides is easy to be too long or too short due to different thicknesses of the door plates, when the distance between the fixed column 11 of the lock head body 10 of the door lock handle on one side and the connection hole of the door lock handle on the other side is too short, the installation problem can be solved by penetrating long screws, and because the distance is arranged between the connection parts, the situation that the door lock swings due to loose connection is easy to occur after the use time is long, the service life of the door lock is short, and when the distance is too long, the door lock handles on two sides cannot be connected, so the door lock is a main disadvantage of the prior art; the connecting rod 20 is connected to the lock head body 10 at present, so that the connection distance between door lock handles at two sides is adjusted, overlong or too short conditions are prevented, the connection is firmer and more stable, the service life of the door lock is prolonged, and the on-site installation is convenient.
One end of the lock body 10 is connected with a fixing piece 12, and when in use, the fixing piece 12 is used for locking the door lock.
The other end of the lock head body 10 is provided with a key opening 13, and the key opening 13 is used for inserting a key when in use.
To sum up, the connecting rod 20 is detachably and fixedly connected above the fixing column 11, so that the connection distance between two sides is adjusted, overlong or too short conditions are prevented, the connection is firmer and more stable, the service life of the door lock is prolonged, and the on-site installation is convenient.
