technical field

The utility model relates to a lockset.

Background technique

At present, electronic anti-theft locks are widely used in various occasions to achieve the purpose of anti-theft, but in the process of use, the traditional electronic anti-theft locks have the following problems: 1), the traditional electronic locks are all through the handle mandrel and the main transmission gear Make a clutch device, or directly lock 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, the probability of failure is high, and the handle mandrel must be reset accurately, otherwise the clutch cannot be disengaged or engaged, which will affect the normal use of the lock. The latter structure directly acts on the movable block due to the force of pressing 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 is bent after bending. Failure to retract causes the entire lock to fail to open. 2) Traditional electronic locks use electromagnets as control drives. This type of lock consumes a lot of power, and has poor anti-vibration and 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 situation of normal use, or lock body also prompts to change new battery, just causes can't open because of insufficient power, brings great inconvenience to the user. 3) The traditional electronic lock driven by an electromagnet, the mechanical opening method is to separate the electromagnet armature from the separation conversion piece of the clutch device through the mechanical lock head, and the clutch device relies on the return spring to connect the transmission part and the handle mandrel together , only then can it 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 the accumulation of dust in the lock body, the entire lock will not be able to be opened, so it is not suitable for emergency situations, and the processing accuracy of the parts is high. , The structure and installation are complicated. 4), the traditional electronic lock with electromagnet as the control drive, when the legal identity of the user is confirmed, the electromagnet drives the lock body to the open state and cannot automatically return to the locked state, that is, the main bolt and the upper and lower blocks Although it is fully extended, 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 in an open or locked state, so it is not suitable for computer network management and wireless remote control.

Compared with the traditional electronic anti-theft lock, the utility model has the following characteristics:

1. On the basis of the original built-in upper and lower block handle locks, the utility model uses the handle to control the telescopic action of the main lock tongue and the upper and lower block. To open and close the lock, you only need to press down the handle after the identity verification is passed. Or lift the handle in an instant, which saves time and effort, is convenient and fast, and solves the time-consuming and laborious phenomenon that traditional locks rely solely on mechanical keys to open and close the lock. The utility model adopts the method of angle difference between the handle mandrel and the main transmission gear and the oblique tongue shifting block to easily realize the telescopic action of the oblique tongue while the handle is opening and closing the main bolt and the upper and lower blocks. And after the control action is completed, that is, when the main bolt and the upper and lower blocks are in the extended or retracted state, the handle can be smoothly reset to the horizontal state, and is ready for the next action. This structure removes the clutch device between the handle mandrel, the main transmission gear and the slanted tongue shifting block, and adopts the main deadbolt locking device, which greatly simplifies the structure and improves the reliability and durability of the lock.

2. The utility model adopts the method of moving the block to lock the main bolt to achieve the purpose of locking. In the past, electronic locks were made by making a clutch device between the handle mandrel and the main transmission gear, or directly locking 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, the probability of failure is high, and the handle mandrel must be reset accurately, 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 pressing 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 is bent after bending. Failure to retract causes the entire lock to fail to open. However, the utility model adopts the movable block to directly lock the main dead bolt, and the force of the handle is greatly reduced at the movable block after being converted by several groups of parts, so as to ensure that the movable block has sufficient strength. 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. The main bolt locking device of the present utility model adopts a worm wheel 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. Traditional electronic locks use electromagnets as control drives. This type of lock has high power consumption, poor anti-vibration and anti-strong magnetic field performance, and it is very easy to open the lock body through external vibration or contact with magnetic substances, resulting in theft. This structure is extremely unstable, and often cannot be opened under normal use, or the lock body has not prompted to replace a new battery, and it cannot be opened because of insufficient power, which brings great inconvenience to the user.

4. The utility model has two opening methods: one is the electric unlocking method; the other is the mechanical unlocking method. When opening the lock under normal circumstances, use the electrical opening method. In case of electrical failure or emergency, the mechanical opening method is used. 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 bolt is completely disengaged from the limiting groove, and then the handle can be opened. The structure has few parts, simple structure, direct and reliable action. In the past, this kind of electronic lock driven by electromagnet, the mechanical opening method is to separate the electromagnet armature from the separation conversion plate of the clutch device through the mechanical lock head, and the clutch device relies on the return spring to connect the transmission part and the handle mandrel together. , only then can it 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 the accumulation of dust in the lock body, the entire lock will not be able to be opened, so it is not suitable for emergency situations, and the processing accuracy of the parts is high. , The structure and installation are complicated.

5. The utility model is driven by a DC motor. After confirming the legal identity of the user, the electrical part will drive the DC motor to unlock the main bolt. If the user does not retract the main bolt, the upper and lower blocks, and open it Lock, the lock will automatically lock 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. When the user's legal identity was confirmed, the electromagnet-driven lock body was in the open state and could not automatically return to the locked state. 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 in an open or locked state, so it is not suitable for computer network management and wireless remote control. The utility model can be easily connected with computer automation systems of families, communities, 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 to the police station, fire brigade, security room or personal mobile phone according to the preset password, which meets people's pursuit of quick and convenient use, intelligence and high anti-theft performance.
