Description

Technical Field

[0001] This utility model belongs to the field of lock technology and relates to a signal lock body. Background Technology

[0002] Traditional locks typically have a main bolt and a latch. To unlock, the key is inserted into the lock cylinder, and rotating the cylinder moves the main bolt and latch to slide. During unlocking, the lock cylinder rotates, moving the main bolt. After the main bolt retracts into the lock body, it moves the latch back into the lock body. Therefore, unlocking requires turning the key multiple times, making it impossible to achieve synchronized movement of the main bolt and latch, resulting in a long unlocking time and considerable effort.

[0003] The lock housing of a smart door lock also contains a microswitch. When opening or closing the door, the microswitch is triggered by the sliding of the latch bolt, and the electrical signal generated by the microswitch determines whether the door is open or closed. However, this single microswitch is not enough to accurately determine the open / closed state. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems with existing locks by proposing a lock body structure that enables synchronous movement of the main bolt and the latch bolt, and provides accurate feedback on the status of the main bolt, the latch bolt, and the triangular bolt.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A signal lock body includes a lock housing and a main bolt, a latch, and a lock cylinder for inserting a key, all disposed on the lock housing. The lock housing also includes a paddle coaxially arranged with a handle and a dial wheel coaxially arranged with the lock cylinder. The key feature is that a gear pair one is provided between the dial wheel and the main bolt, and when the dial wheel rotates, it drives the main bolt to translate via the gear pair one; a gear pair two is provided between the paddle and the main bolt, and when the paddle rotates, it drives the main bolt to translate via the gear pair two; when the handle drives the paddle to rotate, the paddle abuts against the latch and pushes the latch to translate; a transmission assembly is also provided between the dial wheel and the paddle, and when the key drives the dial wheel to rotate, the dial wheel drives the paddle to rotate via the transmission assembly, thereby driving the latch to translate.

[0007] The lock body also includes a micro switch on the lock housing and a contact plate fixed on the latch. When the latch retracts into the lock housing, the contact plate can press the spring on the micro switch to trigger the micro switch, which is used to detect the state of the latch.

[0008] The lock body also includes a triangular tongue and a second micro switch mounted on the lock housing. The triangular tongue is movably mounted on the lock housing and can translate relative to the lock housing. A return spring is also provided inside the lock housing to drive the triangular tongue to pop out. A second contact plate is fixed on the triangular tongue. When the triangular tongue extends out of the lock housing, the second contact plate can press the spring on the second micro switch to trigger the second micro switch, which is used to detect the state of the triangular tongue.

[0009] The lock body also includes a micro switch three disposed on the lock housing. The gear pair two includes a transmission gear two disposed coaxially with the paddle. A pin is fixed on the transmission gear two. When the main lock tongue extends out of the lock housing, it can drive the transmission gear two to rotate, so that the pin rotates synchronously and presses the spring on the micro switch three to trigger the micro switch three, which is used to detect the state of the main lock tongue.

[0010] In one of the signal lock bodies described above, a plastic bracket is fixed inside the lock housing, and the micro switch one, micro switch two, and micro switch three are mounted on the plastic bracket.

[0011] In the aforementioned signal lock body, a guide rod is fixedly mounted on the latch. One end of the guide rod is fixedly connected to the latch, and the other end is fixedly connected to the aforementioned contact plate. When the lever rotates, it can push the contact plate, the guide rod, and the latch as a whole to move and switch the latch.

[0012] In the aforementioned signal lock body, the transmission assembly includes a transmission plate and a transmission pin. One end of the transmission plate is rotatably mounted on a paddle via a rotating shaft, and a guide groove is formed on the other end. A protrusion is also fixedly provided on the end of the transmission plate near the guide groove. The transmission pin is fixedly mounted on the lock housing and inserted into the guide groove. A paddle block is fixedly provided on the paddle wheel. When the paddle wheel rotates until the paddle block abuts against the protrusion, the paddle wheel continues to rotate and pushes the protrusion and the transmission plate to translate along the guide groove through the paddle block, so that the transmission plate pushes the paddle to rotate.

[0013] In the aforementioned signal lock body, the first gear pair includes a first transmission gear coaxially arranged with the dial wheel and a first intermediate gear rotatably arranged on the lock housing. The first intermediate gear meshes with the first transmission gear. When the dial wheel rotates to the point where the dial block abuts against the first transmission gear, the dial wheel continues to rotate and pushes the first transmission gear and the first intermediate gear to rotate through the dial block. The second gear pair includes a second intermediate gear rotatably arranged inside the lock housing. The second intermediate gear meshes with the second transmission gear and is fixedly connected to the first intermediate gear.

[0014] In the aforementioned signal lock body, a guide groove is provided on the main lock tongue, and a push block is fixed on the intermediate gear two. The push block is inserted into the guide groove. When the transmission gear one or the transmission gear two rotates, it can drive the intermediate gear one or the intermediate gear two to rotate, so that the push block pushes the main lock tongue to move along the guide groove.

[0015] In the aforementioned signal lock body, the lock housing includes a lock shell and a lock cover, a gear pair is disposed in the inner cavity of the lock shell and the lock cover, a gear limiting plate is fixed on the lock shell, and a transmission gear is rotatably disposed between the gear limiting plate and the lock cover.

[0016] In the aforementioned signal lock body, both ends of the transmission gear one are provided with arc-shaped bosses, the gear limiting plate is provided with an arc-shaped groove one, and the lock cover is fixed with two sets of coaxial limiting protrusions, forming an arc-shaped groove two between the two limiting protrusions. The two arc-shaped bosses on the transmission gear one are respectively embedded in the arc-shaped groove one and the arc-shaped groove two and slide back and forth along the arc-shaped groove one and the arc-shaped groove two.

[0017] In one of the signal lock bodies described above, the gear limiting plate is riveted and fixed to the lock housing.

[0018] In the aforementioned signal lock body, the gear limiting plate is provided with several rivet plates integrally formed therewith, and the lock shell is provided with several rivet holes corresponding to each rivet plate, with each rivet plate inserted into its corresponding rivet hole.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the lock cylinder is turned by the key, the dial wheel drives the main lock tongue to move horizontally through the gear pair to unlock or lock. At the same time, the dial wheel drives the pawl to rotate through the transmission rod, so that the pawl pushes the slant tongue to move horizontally to achieve synchronous movement, which is more labor-saving.

[0021] 2. When the latch retracts into the lock housing, it triggers micro switch one to detect the latch status and determine whether the door is locked; when the bolt extends out of the lock housing, it triggers micro switch two to detect the bolt status and determine whether the door is open or closed; when the main bolt extends out of the lock housing, it triggers micro switch three to detect the main bolt status and determine whether the door is locked.
