Description

Technical Field

[0001] The utility model relates to the technical field of smart locks, and in particular to an automatically locked smart lock. Background Art

[0002] With the advancement of science and technology and the development of society, people's demand for home security is increasing day by day. As an important part of modern home security, smart locks have been widely used. However, existing smart locks still have some defects when used. For example, if a smart lock is installed on a double door, if one side of the door panel is not fixed, the bolt cannot be effectively fixed because both sides of the door panel can rotate. When the bolt inserted into the lock box is pushed hard against the door panel, it will be squeezed out of the lock box, so that the door can be easily opened, which is not very safe to use.

[0003] In order to solve the above problems, we propose an automatic locking smart lock that can automatically reinforce and lock the lock bolt to improve security. Utility Model Content

[0004] In order to overcome the shortcomings of existing smart locks that, when used on double doors, they have to be forced open and are not very safe, the utility model provides an automatically locking smart lock that can automatically reinforce and lock the lock bolt to improve safety.

[0005] An automatically locking smart lock includes a main body, a plug rod is slidably connected inside the main body, a connecting box is slidably connected to the side of the plug rod away from the main body, a rotating wheel is rotatably connected to the main body, the rotating wheel is used to control the extension and retraction of the plug rod, and also includes a small cylinder, two small cylinders are fixedly connected in the connecting box, and a locking frame is fixedly connected between the telescopic ends of the two small cylinders.

[0006] As a further preferred solution, a groove adapted to the locking frame is formed on a side of the insertion rod away from the main body.

[0007] As a further preferred solution, it also includes a rack, which is fixedly connected to the bottom end of the insertion rod, a gear shaft is rotatably connected inside the main body, the gear shaft is meshed with the rack, a connecting shaft is rotatably connected inside the main body, and a flat belt is connected between the connecting shaft and the gear shaft through a pulley.

[0008] As a further preferred solution, it also includes a rotating plate, which is rotatably connected to the main body, and two vertically symmetrical baffles are slidably connected to the main body, and two first springs are connected between the baffles and the main body.

[0009] As a further preferred solution, it also includes a vertically symmetrical second spring, which is connected to the main body, and a small cylinder is connected to the tail end of the second spring, which is stuck in the rotating plate.

[0010] As a further preferred solution, it also includes a handle, which is fixedly connected to the main body and the connection box respectively.

[0011] The utility model has the following advantages: 1. After the main body controls the insertion rod to slide to the right and insert it into the connection box, the small cylinder shortens and drives the locking frame to slide to the left and snap into the groove to reinforce and lock the insertion rod, thereby preventing the insertion rod from being hard squeezed out of the connection box, thereby improving the safety of use.

[0012] 2. The cooperation of the rotating plate and the baffle can cover and protect the connecting shaft to prevent the connecting shaft from being accidentally touched. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Embodiment 1: An automatic locking smart lock, such as Figure 1 and Figure 2 As shown, it includes a main body 1, an insertion rod 101, a connecting box 2, a rotating wheel 3, a small cylinder 4 and a locking frame 5. The insertion rod 101 is slidably connected in the main body 1, and the connecting box 2 is slidably clamped on the right end of the insertion rod 101. The rotating wheel 3 is rotatably connected to the lower left part of the main body 1. The rotating wheel 3 is used to control the extension and retraction of the insertion rod 101. The upper and lower parts of the connecting box 2 are fixedly connected with small cylinders 4, and a locking frame 5 is fixedly connected between the telescopic ends of the upper and lower small cylinders 4. The right end of the insertion rod 101 is provided with a groove adapted to the locking frame 5.

[0022] like Figure 1 As shown, a handle 15 is also included, and the front sides of the main body 1 and the connection box 2 are fixedly connected with the handle 15.

[0023] When using the device, the staff installs the main body 1 and the connecting box 2 on the door panels on both sides respectively, and the staff can control the extension and retraction of the plug rod 101 from the inside of the door through the rotating wheel 3. When the staff relies on the main body 1 to control the plug rod 101 to slide to the right and insert it into the connecting box 2 from outside the door, the main body 1 will control the small cylinder 4 to shorten, and the shortening of the small cylinder 4 drives the locking frame 5 to slide to the left. After sliding to the left, the locking frame 5 is stuck in the groove to reinforce and lock the plug rod 101, so as to prevent the plug rod 101 from being hard squeezed out of the connecting box 2, so as to improve the safety of use. When the staff relies on the main body 1 to control the plug rod 101 to slide to the left, the small cylinder 4 extends accordingly and drives the locking frame 5 to move to the right and reset.

[0024] Embodiment 2: Based on embodiment 1, Figure 3 As shown, it also includes a rack 6, a gear shaft 7, a connecting shaft 8 and a flat belt 9. The rack 6 is fixedly connected to the lower side of the insertion rod 101, the gear shaft 7 is rotatably connected to the lower right part of the main body 1, the gear shaft 7 is meshed with the rack 6, the connecting shaft 8 is rotatably connected to the lower left part of the main body 1, and a flat belt 9 is connected between the connecting shaft 8 and the gear shaft 7 via a pulley.

[0025] When using this device, when the smart lock is out of power and cannot automatically control the insertion rod 101 to move left and right, the staff can use tools to control the rotation of the connecting shaft 8. The rotation of the connecting shaft 8 controls the rotation of the gear shaft 7 through the flat belt 9. The rotation of the gear shaft 7 can drive the rack 6 to move to the left, and then manually control the insertion rod 101 to move to the left to achieve the purpose of manual unlocking.

[0026] like Figure 1 and Figure 4 As shown, it also includes a rotating plate 10, a baffle 11 and a first spring 12. The rotating plate 10 is rotatably connected to the lower left part of the main body 1, and the baffle 11 is symmetrically connected to the lower left part of the main body 1. Two first springs 12 are connected between the baffle 11 and the main body 1.

[0027] like Figure 5 and Figure 6 As shown, it also includes a second spring 13 and a small cylinder 14. Six second springs 13 symmetrically arranged in an upper and lower direction are fixedly connected to the lower left part of the main body 1. The tail end of the second spring 13 is connected to the small cylinder 14, which is inserted into the rotating plate 10.

[0028] In the initial state, the small cylinder 14 is stuck in the rotating plate 10, thereby fixing the position of the rotating plate 10. The rotating plate 10 can cover the baffle 11 and the connecting shaft 8 to prevent the connecting shaft 8 from being accidentally touched. When it is necessary to manually control the plug rod 101 to unlock, the staff controls the rotating plate 10 to rotate forward and open. Under the action of the expansion and contraction of the second spring 13, the small cylinder 14 can be squeezed upward by the rotating plate 10, and then disengaged from the rotating plate 10. After the rotating plate 10 is opened, the staff controls the upper and lower baffles 11 to slide back to back and open, and the first spring 12 is deformed. At this time, the connecting shaft 8 is exposed, and the staff can manually unlock it with the help of tools. After unlocking is completed, the baffle 11 is released. Under the action of the reset of the first spring 12, the baffle 11 slides toward each other and resets. Then the staff pushes the rotating plate 10 to rotate backward and close, and it is locked by the small cylinder 14.
