Door lock with adjustable handle angle

Abstract

A door lock with an adjustable handle angle, comprising a lock case unit, a movable clamping part, a linkage mechanism connected to the clamping part, at least one lock connected to the clamping part and the linkage mechanism The first elastic element between one of them and the lock case unit, the handle knob that is rotatably arranged on the lock case unit and has a pushed surface, is connected to the handle knob and the lock case unit The second elastic element, which has the potential energy to drive the handle knob to rotate in the first rotation direction, is movably arranged on the lock housing unit and has a pushing surface and a locking joint that is in sliding contact with the pushed surface. The slider module of the hole, and the adjusting bolt that is rotatably but immovably arranged on the lock case unit, the first elastic element is used to drive the locking part to move relative to the lock case unit, so The adjusting bolt is screwed to the locking hole, and is used to drive the slider module to drive the handle knob to rotate in the second rotation direction.

Description

technical field [0001] The invention relates to a door lock, in particular to a door lock with adjustable handle angle. Background technique [0002] Such as figure 1 , 2 As shown, an existing channel lock includes a lock case 1, a deadbolt 2 that can be moved left and right on the lock case 1, a left and right moveable set on the lock case 1 and connected with the dead bolt 2 connected link 3, two first tension springs 4 connected between the link 3 and the lock case 1, a handle rotatably arranged on the lock case 1 and having a mounting hole 501 The rotary knob 5 , a second tension spring 6 connected between the handle rotary knob 5 and the lock case 1 , and a handle 7 installed in the installation hole 501 . Thereby, the first tension spring 4 can drive the linkage 3 to drive the lock tongue 2 to move leftward relative to the lock housing 1 to protrude out of the lock housing 1, so that the door can be closed, and when When the user holds the handle 7 and turns the ha...

Problems solved by technology

[0003] However, when the handle 7 is installed in this kind of channel lock, the horizontal state of the handle 7 cannot be adjusted. In this way, due to the production tolerance or assembly tolerance of the parts, the handle 7 will appear slightly drooping or sagging after the assembly is completed. In the upturned state, for example, if the upper and lower tolerances of the part of the lock housing 1 in contact with the top surface of the handle knob 5 are too large, it may cause the handle knob 5 to turn more clockwise. Some angles, so that the handle 7 presents a slightly drooping state, or cause the second tension spring 6 to pull the handle knob 5 to turn counterclockwise at an angle, so that the handle 7 presents a slightly upturned state, All these will affect the quality perception of the appearance of this channel lock
