[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] like Figures 1-6 As shown, an intelligent optical interlocking structure with external locking and internal opening includes: a door body 1 and a door frame 2. A lock body 17 is installed on the door body 1 through a lock body mounting plate 3 and an inner fixing plate 4. The output end of the lock body 17 is provided with a lock tongue 6. The lock body 17 controls the lock tongue 6 to lock or open with the door frame 2 during rotation. The lock body 17 is connected to an inner core 13 through a transmission structure. A rotating sleeve 12 is fitted on the inner core 13. The end of the rotating sleeve 12 is connected to the lock tongue 6 through a lock tongue screw 7. A limiting pin 11 passes through the inner core 13. The rotating sleeve 12 has a clearance notch at the position corresponding to the limiting pin 11, so that the rotating sleeve 12 can rotate relative to the inner core 13 at a certain angle.
[0022] It should be noted that the automatic control part of the electronic lock is existing technology and is not limited here. It can be implemented by combining with the structure of existing technology. This application mainly limits how to realize the manual rotation of the bolt 6 and automatic reset so as to open or lock from the inside without operating the lock body 17 from the inside of the door. The structure of the bolt 6 can be plate-shaped, block-shaped or other structures.
[0023] This utility model discloses an intelligent optical interlocking structure with external locking and internal opening. A torsion spring baffle 10 is installed on the inner fixed plate 4. The torsion spring baffle 10 is connected to one end of the torsion spring 8. The torsion spring baffle 10 restricts the rotation of one end of the torsion spring 8. The other end of the torsion spring 8 is a free end. The free end is restricted by a reset screw 9 installed on the lock tongue 6. The reset screw 9 is fixed on the lock tongue 6. In its natural state, the torsion spring 8 keeps the reset screw 9 in a relatively fixed position.
[0024] It should be noted that the torsion spring 8 can have various structures. In this application, it is provided as a right-angle structure, that is, one end is restricted to rotation by the torsion spring baffle 10, and the other end is a free end. During the rotation of the locking tongue 6, the reset screw 9 makes the angle of the torsion spring 8 greater than 90 degrees, causing the locking tongue 6 to leave the locked position. When the rotational force on the locking tongue 6 disappears, the locking tongue 6 is reset under the action of the rebound force of the torsion spring 8.
[0025] The utility model discloses an external lock and internal opening type intelligent optical interlocking structure, transmission structure includes the connecting sleeve 14 of the lock axle 16 connection with lock body 17, the connecting sleeve 14 is connected with the lock axle 16 through connecting screw 15, the other end of connecting sleeve 14 is connected with inner core 13.
[0026] The utility model discloses an external lock and internal opening type intelligent optical interlocking structure, be provided with electronic control box 20 on the inner fixed plate 4, electronic control box 20 is connected with lock body 17 through lock control line 21.
[0027] The utility model discloses an external lock and internal opening type intelligent optical interlocking structure, be provided with lock handle 18 on lock body 17.
[0028] The utility model discloses an external lock and internal opening type intelligent optical interlocking structure, be provided with emergency lock hole 19 on lock body 17.
[0029] The utility model discloses an external lock and internal opening type intelligent optical interlocking structure, the door frame 2 with the lock bolt 6 position corresponding place has the lock bolt baffle 5 along the length direction and sets up.
[0030] Principle is briefly stated:
[0031] From Figure 5 It can be known that the lock body 17 contains a circuit board, and is connected with the electronic control box 20 through the lock control line 21. Therefore, the lock can realize wireless on-off by the APP control function of the smart phone. In addition, if the wireless control circuit part has a fault, the electronic emergency key can be used to open and close the lock from the emergency lock hole 19, which is the structure of the prior art, and will not be described here.
[0032] The above is the situation of opening and closing the lock from outside the door. However, the focus of the application is the structure of opening the lock manually without key from inside the house. Figure 5 It can be seen that when the lock bolt 6 is rotated clockwise by hand, the reset screw 9 fixed on the upper corner thereof will also rotate clockwise, and at this time, the upper supporting rod of the torsion spring 8 will be pressed. When the torsion spring 8 is twisted to a certain angle, the door can be opened. During the twisting process, only the rotating sleeve 12 rotates, and is limited by the limiting block pin 11, so that it can only rotate to a certain angle. For example, Figure 2 When the lock bolt 6 is rotated manually from inside, the inner core 13 does not rotate when the rotating sleeve 12 rotates. After the hand is released, the lock bolt will return to the original position under the reset action of the upper supporting rod of the torsion spring 8.
[0033] Since the limiting block pin 11 is fixed on the inner core 13, when the lock is opened from outside the door, the inner core 13 can also drive the rotating sleeve 12 to rotate clockwise, and the rotating sleeve 12 can also reset under the action of the upper supporting rod of the torsion spring 8.
[0034] In the description of the utility model, it is necessary to explain, the term "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "internal", "external" and so on indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0035] In the description of the utility model, it is necessary to explain, unless otherwise expressly provided and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, can also be detachable connection, or integrally connected, can be mechanical connection, can also be electrical connection, can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
