Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to an automatic door locking mechanism with a detection function. Background Art

[0002] In modern life, automatic door locking mechanisms are widely used in various places such as homes, office buildings, and shopping malls to improve safety and convenience. These automatic door locking mechanisms use intelligent design to automatically open and close the door, greatly improving the user experience. However, in actual applications, ensuring that the door is fully closed before it is activated is a key safety requirement. During operation, some equipment and devices may cause serious safety hazards if the door is not fully closed before starting. For example, if the door of some industrial equipment is left half-open during operation, it may cause injury to the operator or even damage the equipment. Although traditional automatic door locking mechanisms can achieve automatic closing of the door, they often lack effective detection mechanisms to confirm the door's closure status. Utility Model Content

[0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0014] Beneficial effects of the utility model:

[0015] When the device is in use, the electric telescopic rod is used to push the insertion rod to move outward, and the door body is closed by inserting the insertion rod into the slot of the peripheral device. The operation is simple and convenient. At the same time, when the insertion rod moves outward, the setting of the inclined surface causes the elastic movable rod to move upward to a certain position under the action of its own elasticity. At this time, the pressure applied to the pressure sensor changes and is detected by the signal converter, which converts it into a closing electrical signal and transmits it outward to confirm that the door is locked successfully. When the door body is opened, the insertion rod is in an inwardly contracted state, squeezing the elastic movable rod to move downward, and the signal converter converts the state at this time into an opening and closing electrical signal and transmits it outward, effectively detecting the opening and closing state of the door body, and avoiding the state of the door body not being fully closed when it needs to be closed.

[0027] Among them, the mounting assembly 106 includes a mounting screw 106a, and a plurality of mounting holes are respectively opened on the mounting frame 101 and the side plate 102, which cooperate with the mounting screw 106a. A hexagonal cylindrical head 106b is fixedly connected to the mounting screw 106a, and an elastic pad 106c is provided on one side of the hexagonal cylindrical head 106b. The device is installed by cooperating with the mounting screw 106a and the mounting hole. At the same time, the setting of the hexagonal cylindrical head 106b facilitates the user's installation.

The insertion rod 104 is restricted by the cooperation of the limit screw 111 and the limit slot 112 so that it can only move in the horizontal direction.

[0029] Furthermore, the movable end of the electric telescopic rod 103 is universally connected with a fisheye joint 105, and the fisheye joint 105 is rotatably connected to the insertion rod 104. Through the setting of the fisheye joint 105, the electric telescopic rod 103 and the insertion rod 104 are connected.

[0030] Furthermore, a slope is provided at the right end of the insertion rod 104, which cooperates with the roller 109.
