Embodiment Construction

[0013] A specific implementation of a multifunctional door latch will be described in detail below in conjunction with the embodiments and accompanying drawings, but the specific implementation of the present invention is not limited to the following embodiments.

[0014] like figure 1 As shown, the latch body 1 is made of a whole piece of steel plate, and a flat-headed deadbolt notch 6 and a wedge-shaped deadbolt notch 7 are opened on the latch body. The first movable plate 3 and the second movable plate 4 are assembled, the first movable plate 3 and the second movable plate 4 are connected by a curved steel sheet 5 and a spring hinge 8 to connect and assemble it on the latch body 1, and the hinge is installed on the movable plate The nail hole and the nail hole for installing the hinge on the door latch body 1 are pierced to facilitate the reverse assembly of the hinge, so that the door latch can be used for left-handed or right-handed door opening. It is convenient to use ...

Abstract

The invention relates to a door catch which is matched with a locking head for use in a door plate to close a door. The door catch comprises a door catch body which is provided with a ferrule and a rotary wheel for fixing the door catch and is provided with a flat spring bolt notch and a wedged spring bolt notch at the same time, wherein a movable plate I and a movable plate II are arranged at the edges of the flat spring bolt notch and the wedged spring bolt notch; the movable plate I and the movable plate II are fixedly connected through a curved steel sheet and are movably connected to the door catch body through a spring hinge. The door catch body is further provided with an iron rod handle which can be used for opening the door catch indoors. The multifunctional door catch provided by the invention overcomes the defects that the door catch does not satisfy the matching demand on a lock, is insufficient in structural strength, complex in structure, dependent on a power system and the like; opening and closing functions of the door catch structure can be relatively well realized while the structure is simplified and the cost is lowered; meanwhile, the structural design of the door catch is totally a mechanical design, so that the dependency of the system on electrical energy is completely removed, and the technical improving effect is quite obvious.

Description

technical field [0001] The invention relates to door lock technology, in particular to a door bolt used in a door panel to close a door in cooperation with a lock head. Background technique [0002] At present, because the structural steel materials on the side of the notch of the latch tongue in the prior art are all fixed and positioned, its function can only be applied to the ordinary lock with an indoor lock shaft and the lock can be opened by getting the key indoors. In use, for some patent No. 201310166329.0 and patent No. 201320244452.5 locks without indoor lock shafts, in the closed state, the flat deadbolt and wedge-shaped deadbolt are locked, and there are other locks in the lock to reinforce the flat deadbolt, wedge-shaped deadbolt In the case of the locking function of the type deadbolt, the indoor personnel cannot normally open the door and go out by using the existing traditional door latch. [0003] There is also a kind of anti-theft bolt, such as the authori...
