The utility model has the following advantages:

1. On the basis of the original built-in heaven and earth handle lock, the handle is used to control the main bolt, the sky and earth pull block and the telescopic action of the oblique bolt. Opening and closing the lock only needs to be done after the identity verification is passed, or the insertion and anti-theft After the mechanical key matched with the lock head is turned at an angle of 90 degrees along the opening direction, the action of opening and closing the lock is completed instantly by pressing down the handle or lifting the handle, which is time-saving, labor-saving, convenient and quick, and realizes the purpose of quick closing and quick opening of the lock , It solves the time-consuming and laborious phenomenon that traditional locks rely solely on mechanical keys to open and close the locks. And this new type of lock adopts the method of angle difference between the handle mandrel and the main transmission gear, the oblique tongue shifting block, and the swinging block. Control the telescopic action of the oblique bolt, and after the control action is completed, that is, when the main bolt, the sky and the ground block are in the extended or retracted state, the handle can be smoothly reset to the horizontal state, and it is ready for the next action, unlocking Finally, when the handle is released, the swing block will automatically reset to the locked state by using the torsion force of the torsion spring of the swing block. At this time, pressing the handle again will not make the latch bolt retractable, realizing the purpose of closing the door quickly and locking it. Put an end to the theft and "stalking" phenomenon caused by forgetting to lift the handle to lock after closing the door. This structure removes the clutch device between the handle mandrel and the main transmission gear, the oblique tongue shift block, and the swing block, and adopts the double locking device of the main bolt and the swing block, which greatly simplifies the structure and improves the safety of the lock. reliability and durability.

2. The lock adopts the method of locking the main bolt and the swinging block at the same time to achieve the purpose of double locking. In the past, electronic locks were made by making a clutch device between the handle mandrel and the main transmission gear, or directly restraining the handle mandrel. Compared with the former structure, there are more parts, the strength of the transmission parts is poor, the machining accuracy is high, the process is complicated, and the failure rate is high. The mandrel reset needs to be accurate, otherwise the clutch cannot be disengaged, which will affect the normal use of the lock. The latter structure directly acts on the movable block due to the force of the handle, and the movable block is subjected to a large force. In the case of locking, when the destructive force is opened, the movable block is easy to bend, and the movable block cannot be bent after bending. Retraction causes the entire lock to be unopenable or destructively opened. In this new type of lock, the movable block directly locks the main bolt and the swing block, and the force of the handle is greatly reduced at the block through several sets of conversions to ensure that the block has sufficient strength, while the swing block locking device The movable block is used to lock the swing block. The swing block uses the principle of the lever to greatly reduce the torsional force of the handle at the block. The perfect combination of the swing block locking device and the main bolt locking device is Any kind of destructive opening method is far behind. There is a gear transmission mechanism between the handle and the main bolt shifting block, the structure is simple, the general production process is easy to realize, the use reliability and durability of the lock body are greatly improved, and the production cost is reduced.

3. When the electric opening method is used, the main deadbolt locking device adopts a worm gear and a worm drive mechanism. Through the torsion spring fixed on the worm wheel, the torque of the worm wheel rotation is transmitted to the movable block, so that the movable block moves downward or upward to complete the action of unlocking and locking. The structure has the advantages of simple structure, convenient installation, stable transmission, precise rotation angle, anti-vibration, anti-strong magnetic field and other environmental influences. Due to the flexible effect of the torsion spring fixed on the worm wheel, it avoids the phenomenon that when the motor rotates at high speed, it cannot stop immediately because the rotation is in place, resulting in overload, and even the phenomenon of jamming and burning of the motor. The worm gear and worm mechanism also have the effect of force amplification, so that when the motor is driven, the required power consumption is small, which realizes real micro power consumption, reduces the power consumption of the battery, and greatly increases the number of times of use. The prompt is correct. In the past, this type of lock used electromagnets as the control drive. This type of lock has high power consumption, poor anti-vibration, and anti-strong magnetic field performance. It is very easy to open the lock body through external vibration or contact with magnetic substances, and theft occurs . And this structure is extremely unstable, often can't be opened under the normal use situation, or lock body also prompts to change new battery, just causes can't open because of insufficient power, brings great inconvenience to the user.

4. The lock has two opening methods, one is electrical unlocking method; the other is mechanical unlocking method. Electrical unlocking methods include electronic lock head, magnetic card, TM card (button key), ID proximity card, wireless remote control, computer door lock control system, fingerprint, eye mask and other biometric technologies, etc. The mechanical unlocking method is to use the mechanical key matched with the anti-theft lock to insert the exposed or concealed anti-theft lock to open the lock. Anti-theft locks include crescent double-row juxtaposed marble locks, blade locks, computer key locks, smart key locks, angle key locks, cross key locks, "S" slot key locks, etc. When the electrical opening method is used, the mechanical opening method is used when the electrical failure or emergency is special. The mechanical opening adopts the method of directly moving the block shifting block with the lock head fork, and the movable block is forcibly pressed down until the main lock tongue and the limit groove of the swing block are completely disengaged, and the handle can be opened by pressing down. The structure has few parts, simple structure, direct and reliable action. In the past, this type of electronic lock driven by an electromagnet used a mechanical lock to separate the electromagnet armature from the separation conversion piece of the clutch device. The clutch device relied on the return spring to connect the transmission part and the handle mandrel. can be turned on. This structure can complete the unlocking action through the mutual transmission of several parts, and there is a serious potential safety hazard in an emergency. Because the lock head cannot directly move the clutch device, when the clutch device fails or the return spring cannot be reset due to dust accumulated in the lock body, the entire lock will not be able to be opened, so it is not suitable for emergency situations, and the parts are processed with high precision. The structure and installation are complex.

5. The lock is driven by a DC motor. When the lock confirms the legal identity of the user, the electrical part will drive the DC motor to unlock the main lock tongue and handle mandrel. If the user does not lock the main lock The tongue, the sky and the earth pull block and the oblique tongue are retracted, and the lock is opened, and the lock will be automatically locked to ensure the anti-theft performance of the lock. And the switch record of the motor in the lock body and the switch state of the micro switch can be recorded by the computer, so that it can be clearly known whether the lock is in an open or locked state. In the past, the electromagnet was used as the control-driven electronic lock. After the legal identity of the user was confirmed, the electromagnet-driven lock body was in the open state and could not automatically return to the locked state. Fully extended state, but the lock can still be opened, so there is a potential safety hazard. Through the opening record of the electromagnet and the switch state of the detection switch, it is impossible to know whether the lock is now in an open or locked state. Therefore, it is not suitable for computer network management and wireless remote control. However, the utility model can be easily connected with the computer automation systems of family quarters, hotels, government agencies, and office buildings, and can achieve centralized authorization, unified management, real-time monitoring, time-sharing, hierarchical and partition control, information sharing, and normally open and normally closed functions. In an emergency, it can be connected with the police station, fire brigade, security room, and personal mobile phone according to the preset password. It satisfies people's pursuit of fast and convenient use, intelligence and high anti-theft performance, which cannot be achieved by electronic locks driven by electromagnets in the past.
