Description

Lock set

Technical Field

The invention relates to the technical field of locks, in particular to a lock.

Background

At present, along with the continuous development of communication technology and the continuous application in the field of electronic locks, the lock control technology is continuously developing towards intellectualization. Users no longer satisfy the unlocking and locking control of the lock, and the requirements of state monitoring, theft prevention, low power consumption, shell protection grade, appearance, simple and convenient assembly and the like of the electronic lock are gradually increased.

In the prior art, the resistance and the external resistance of a locking mechanism are generally required to be overcome when the existing electronic lock adopts a driving mechanism such as a motor and the like to unlock, and a driving mechanism with double solenoid is adopted for improving the anti-theft performance of some intelligent padlocks, so that the power consumption of the driving mechanism is high, the electric quantity output of long-time high power is difficult to ensure by adopting a wireless power supply mode, and the condition of unlocking failure caused by insufficient power supply of the driving mechanism can be generated. The electronic lock powered by the built-in battery can reduce the service life of the battery due to higher power consumption of the driving mechanism, needs to maintain and replace the battery, and simultaneously has the problems of large current, high temperature, accelerated aging of components and parts and the like, thereby influencing the service life of the electronic padlock.

In the prior art, the electronic lock which adopts double solenoids or a single solenoid as a driving element has the following advantages and disadvantages: when two solenoids are adopted, the whole lockset is failed as long as one solenoid fails; the use of a single solenoid reduces the probability of a lock failure due to a failure of the solenoid. For example, two solenoids are used in a dual-solenoid lock, the failure rate of a single solenoid is 100%, and the failure rate of a single solenoid is 50% when the single solenoid is used in a dual-solenoid lock, but when the single solenoid is used, when the electronic lock is subjected to external forces such as knocking, jolting and beating, due to the weight of the solenoid spindle and the relative softness of the return spring of the solenoid, the instant retraction of the solenoid under the action of the inertia force causes the electronic lock to be opened abnormally, thereby reducing the anti-theft performance of the electronic lock.

The application occasions of the existing electronic lock have stronger and stronger requirements on state detection, particularly the electronic lock applied in the field of electric power misoperation prevention, the state detection is very important, the requirement on the conformity degree of the detected lock state and the actual lock real state is very strict, and the phenomenon of 'false closing' is particularly not allowed to occur, wherein the 'false closing' means that the lock state fed back on a lock release device is locked, the lock real state is an unlocked state, otherwise serious supervision loopholes exist, and serious electric power accidents can be caused. The existing electronic lock generally adopts magnetic steel to match with a Hall element for position detection, but the position detection precision of the detection mode is low, so that a false closing phenomenon possibly exists;

the requirement on the shell protection grade of an electronic lock applied outdoors is relatively high, foreign matters such as dust, rainwater and the like are difficult to effectively isolate in the unlocking and locking process and in the unlocking state of an electronic padlock adopting bilateral locking, when the foreign matters enter the inside of the electronic padlock, the mechanical parts of the electronic padlock are possibly blocked and unsmooth in action, the use experience is influenced, and even the mechanical parts are blocked to cause the failure of the whole electronic padlock; the abnormal conditions such as corrosion and aging of internal parts, short circuit and damage of elements and devices can be caused, the service life of the electronic padlock is reduced, and even the electronic padlock can not be used normally;

the existing electronic padlock still has a plurality of parts, so that the factors causing failure risks are increased, the assembly efficiency is reduced, the production efficiency is influenced, some pins, plugs, screws and the like are leaked out of the outer surface of the electronic lock, the appearance of the electronic lock is influenced, and the technical inspiration for violently cracking the electronic padlock can be provided for lawbreakers.

In the embodiment, the accommodating area 11 is formed on the lock body 10, and the accommodating area 11 is locked or unlocked by the lock pin assembly 20, so that the lock forms a horizontally-opening padlock, on this basis, two groups of locking assemblies, namely the first locking assembly 30 and the second locking assembly 40, are arranged, and the second locking assembly 40, the first locking assembly 30 and the lock pin assembly 20 can be sequentially locked or unlocked, which is beneficial to keeping the direction and the position of the driving assembly 50 on one hand, and on the other hand, compared with locks such as padlocks which are only provided with one group of locking assemblies, the lock can be unlocked only by two groups of locking assemblies due to the two groups of locking assemblies, so that the lock can be unlocked by two groups of locking assemblies, the vibration unlocking difficulty is higher, and the anti. In addition, the positions of the locking pin component 20 and the second locking component 40 are respectively detected by adopting the sensing component and the detecting component 62, and the detection result is comprehensively analyzed and comprehensively judged according to the positions of the sensing component and the detecting component, so that the locking and unlocking state displayed by the unlocking device and the reliability of the operation result after the locking device changes the working state are ensured, the accuracy and the reliability of the locking and unlocking state of the locking device obtained by an operator are ensured, the problem of supervision loopholes such as false locking is avoided, and the effective and reliable supervision of the locking device is ensured. And the whole tool to lock does not increase too much spare part, and spare part is small in quantity, and the assembly is simple, and manufacturing is convenient and fast, low in production cost.

It should be noted that the lock of the present embodiment is a horizontal-opening padlock, that is, the lock body 10 is a concave structure as a whole, and has an accommodation area 11 with an open upper surface, and the lock pin assemblies 20 are transversely inserted into two sides of the accommodation area 11 at the upper portion of the concave structure, so as to control the opening and closing of the accommodation area 11, and thus control the opening and closing of the lock. When the lock is in a locked state, two ends of the lock pin assembly 20 respectively extend into two side edges of the accommodating area 11, so as to close and close the accommodating area 11, and when the lock is in an unlocked state, one end of the lock pin assembly 20 exits from one side edge of the accommodating area 11, so as to avoid opening the accommodating area 11.

As shown in fig. 1, 2, 5, 7 and 8, the sensing assembly includes a first magnetic member 61 and a first sensing member, the first magnetic member 61 is a magnetic steel, and is connected to the locking pin assembly 20 and can move between an unlocking position, a locking position and a pressing position along with the locking pin assembly 20; first response piece is tongue tube or hall element, hall element is adopted to this embodiment, it sets up in lock body 10, and can respond to the position of first magnetic part 61, when the response state of response subassembly is first state, first magnetic part 61 triggers first response piece, when the response state of response subassembly is the second state, first magnetic part 61 does not trigger first response piece, like this, can judge the position of lockpin subassembly 20 through the trigger state of first response piece, thereby confirm the switching lock state of tool to lock.

It should be noted that, because the lock is still in the locked state when the lock pin assembly 20 is located at the pressing position, when the sensing state of the sensing assembly is the first state, it can only be determined that the lock is locked, and as for whether the lock pin assembly 20 is located at the bottom in the locked position or the pressing position, it cannot be determined by the first sensing assembly, at this time, it is necessary to determine the specific position of the lock pin assembly 20 by detecting the position of the second locking assembly 40 by the detecting assembly 62. The detecting member 62 of the present embodiment is a microswitch, when the lock pin assembly 20 is located at the locking position or during the switching process between the pressing position and the unlocking position, the second locking assembly 40 is located at the restricted state position, and the second locking assembly 40 triggers the detecting member 62; when the lock pin assembly 20 is located at the pressing position or the unlocking position, the second locking assembly 40 is located at the free state position, the second locking assembly 40 does not trigger the detection piece 62, so that components with high position sensing precision such as a microswitch and the like are matched with components with low position sensing precision such as a Hall element and the like, and the lock state can be accurately obtained by matching the two parts, specifically, when the first sensing piece and the detection piece 62 are both in the triggering state, the lock pin assembly 20 is located at the locking position or the lock is locked in the switching process of the locking position and the unlocking position; when the first sensing member is in the triggered state and the detecting member 62 is in the non-triggered state, the lock pin assembly 20 is located at the pressing position, and the lock is pressed; when the first sensing member and the detecting member 62 are both in the non-triggered state, the lock pin assembly 20 is located at the unlocking position, and the lock is unlocked.

Of course, the above-mentioned triggering relationship between the first state, the second state and the first sensing element, and the triggering relationship between the position of the limit state, the position of the free state and the detecting element 62 may also be set in reverse, that is, when the sensing state of the sensing element is the first state, the first magnetic element 61 does not trigger the first sensing element, when the sensing state of the sensing element is the second state, the first magnetic element 61 triggers the first sensing element, and when the second locking element 40 is located at the position of the limit state, the second locking element 40 does not trigger the detecting element 62, and when the second locking element 40 is located at the position of the free state, the second locking element 40 triggers the detecting element 62. Accordingly, the position of the latch assembly 20 as indicated by the first sensing member and the sensing member 62 may also be changed.

The present embodiment provides the locking pin assembly 20 with two separable locking pins 21 and shot pins 22 based on the sealing requirements, and in particular, since the shot pins 22 are always located in the lock body 10, it does not fall out of the lock body 10, so that the shot column 22 remains blocked off the lock body 10 for the latching pin 21 to enter and exit the latching hole, when the lock pin assembly 20 is located at the locking position or the pressing position, the locking pin 21 extends into the locking hole, both the locking pin 21 and the bullet column 22 can play the role of blocking the locking hole, when the lock pin assembly 20 is located at the unlocking position, the locking pin 21 exits from the locking hole, and the spring column 22 is still located in the locking hole to play a role of blocking the locking hole, so that the locking hole is always blocked no matter what state the lockset is located, thereby avoided the shut hole to open and leaded to the tool to lock condition of intaking into dirt, guaranteed the holistic leakproofness of tool to lock. Of course, it is also possible to provide the latching pin 21 and the shot column 22 as one integral component.

As shown in fig. 2, 5, 7 and 8, a side wall of the latching pin 21 is formed with a latching groove 211, a top end of the first latching member 30 can be inserted into or withdrawn from the latching groove 211 to lock or unlock the latching pin 21, and a width of the latching groove 211 in a lateral movement direction of the latching pin 21 is greater than a distance between both sides of the first latching member 30, so that the first latching member 30 has a small range of movement space in the latching groove 211, when the locking pin member 20 is located at the latching position, the first latching member 30 abuts against the side wall of the latching groove 211 close to the shot column 22, and when the locking pin member 20 is located at the pressing position, the locking pin member 20 further extends into the lock body 10, and the first latching member 30 further extends into the latching groove 211 by a slight distance and is separated from the side wall of the latching pin 21 close to the shot column 22.

It should be noted that, the latching groove 211 of the present embodiment is formed along the circumference of the latching pin 21, and since the latching pin 21 is rotatable relative to the lock body 10, when the latching pin 21 is inserted into the latching hole, the latching groove 211 is naturally aligned with the first ball 31, i.e. the latching pin 21 is not specially rotated for alignment.

Optionally, the side wall of the pin 22 is formed with an unlocking slot 221, when the locking pin assembly 20 is located at the unlocking position, the locking pin 21 exits from the locking hole, the pin 22 moves to the moving path of the first locking assembly 30, at this time, the unlocking slot 221 is aligned with the top end of the first locking assembly 30, and the first locking assembly 30 extends into the unlocking slot 221, so that the movement of both the pin 22 and the first locking assembly 30 is limited, so that the pin 22 does not exit from the locking hole, and the first locking assembly 30 does not excessively extend into the locking hole.

In this embodiment, the lock further includes a lock pin returning member 80, wherein the lock pin returning member 80 is a spring, and two ends of the spring abut against the end of the lock pin 22 away from the locking pin 21 and the lock body 10, respectively, so as to provide a returning force for moving the lock pin assembly 20 to the unlocking position, so that the lock pin 21 can automatically move to the moving path of the first locking assembly 30 after exiting the locking hole.

Preferably, when the locking pin assembly 20 is in the hold down position, the locking pin return 80 is compressed to the shortest possible length, i.e., when the locking pin assembly 20 is pressed to the hold down position by an external force, the locking pin return 80 cannot be further compressed, and the locking pin assembly 20 cannot pass the hold down position, which is designed to: when the lock is violently cracked by knocking and the like, assuming that at some moment, the first locking assembly 30 further extends into the locking pin assembly 20, the locking pin assembly 20 is located at the pressing position, and the inner core 53 retracts, at this moment, under the condition that no other limitation exists or other limitation conditions are failed, if the locking pin resetting member 80 can still be compressed, the locking pin assembly 20 can further move beyond the pressing position, when the locking pin assembly 20 is released, the locking pin assembly 20 moves to the locking position under the action of the locking pin resetting member 80, the locking pin assembly 20 passes through the pressing position again, so that the locking pin assembly 20 moves back and forth once and passes through the pressing position twice, thereby increasing the possibility of accidental unlocking, and by adopting the arrangement mode of the embodiment, when the locking pin assembly 20 is at the pressing position, the locking pin resetting member 80 cannot be compressed further, and the locking pin assembly 20 cannot pass through the pressing position, the locking pin assembly 20 moves toward the locked position upon release of the locking pin assembly 20 so that the locking pin assembly 20 moves back and forth through the hold down position only once at a time, thereby greatly reducing the likelihood of accidental unlocking. Of course, in other embodiments, a hard stop structure may be added, and the hard stop structure may limit the lock pin assembly 20 to continue moving, which may also reduce the possibility of accidental unlocking.

Besides, besides the lock pin reset piece 80, the lock also comprises a spring column limiting pin 90 and a lock pin limiting pin 100, the side surface of the spring column 22 is provided with a concave part, as shown in fig. 3, the spring column limiting pin 90 is fixedly connected with the lock body 10, extends into the concave part and moves in the concave part so as to control the movement range of the spring column 22 and avoid the situation that the spring column 22 moves over under the driving of the locking pin 21 and the lock pin reset piece 80; the lock pin limiting pin 100 is movably arranged in the lock body 10 and can be matched with the locking groove 211, the lock pin limiting pin 100 is positioned on the other side, namely the left side in fig. 2, of the accommodating area 11 relative to the bullet column 22, the lock pin limiting pin 100 can slide up and down, a spring is arranged between the bottom end of the lock pin limiting pin 100 and the lock body 10, when the lock pin assembly 20 is positioned at the unlocking position, the lock pin limiting pin 100 is aligned with the locking groove 211 and moves upwards under the driving of the spring and extends into the locking groove 211, so that the locking pin 21 can be always kept on the lock body 10, the problem that the locking pin 21 is easy to lose due to the fact that the locking pin 21 is separated from the lock body 10 is avoided, and the lock pin limiting pin 100 is limited by the locking groove 211 without additionally arranging.
