Problems solved by technology

This structure enables the bolt mandrel to rotate unrestricted in the bolt sleeve, which is relatively loose, and the door lock is easy to disengage after being shaken.
In addition, judging whether the existing door lock is locked or not is judged by visually checking the position of the handle. For those who do not know the locked position of the handle, they need to pull the door lock to confirm whether the door panel is locked, which is troublesome.

Embodiment Construction

[0009] like figure 1 A positioning door lock is shown, comprising a handle 1, a bolt housing 4, and a bolt mandrel 2. The bolt mandrel 2 is set in the bolt housing 4, and the handle 1 is fixed on the bolt housing 4 by screws. On the bolt mandrel 2, the door lock is fixed on the door plate by a nut, the inner wall of the door bolt sleeve 4 is provided with a step, and a spring 5 is arranged in the cavity between the step and the door bolt mandrel 2; A limit screw 3 is provided at the tail end of the bolt mandrel 2 to limit the locking position of the door lock.

[0010] Because the spring is arranged between the bolt sleeve seat and the bolt core shaft, the random rotation of the bolt core shaft in the bolt sleeve seat is limited, and the handle is increased simultaneously. When the door lock is working, it is only necessary to turn the handle to drive the bolt mandrel to rotate, and when the door bolt mandrel reaches the limit position, the door lock can be confirmed to reach...

Abstract

The invention discloses a positioning door lock which comprises a handle, a latch sleeve seat and a latch mandrel, wherein the latch mandrel is sleeved in the latch sleeve seat; the handle is fixedly arranged on the latch mandrel through screws; and the door lock is fixedly arranged on a door panel through nuts. The positioning door lock is characterized in that a step is formed on the inner wall of the latch sleeve seat; a spring is arranged in a cavity between the step and the latch mandrel; a limiting screw is arranged at the tail end of the latch mandrel and is used for limiting the locking position of the door lock. According to the positioning door lock disclosed by the invention, the latch mandrel is limited by the spring, so that the latch mandrel is prevented from rotating due to vibration; and meanwhile, the hand feeling of the door lock is increased. Due to the adoption of the limiting screw, a user can accurately know that the door lock reaches the locking position.

Description

technical field [0001] The invention relates to a positioning door lock on an electric cabinet. Background technique [0002] The door lock on the electrical cabinet of the prior art includes a handle, a bolt sleeve, and a bolt mandrel. The bolt mandrel is directly sleeved in the bolt sleeve, and the handle is fixed on the bolt mandrel by screws. This structure enables the bolt mandrel to rotate unrestricted in the bolt sleeve, which is relatively loose, and the door lock is easy to disengage after being shaken. In addition, judging whether the existing door lock is locked or not is judged by visually observing the position of the handle. For people who do not know the locked position of the handle, they need to pull the door lock to confirm whether the door panel is locked, which is troublesome.
