Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of locks, and in particular to an electric-controlled lock. Background Art
[0002] Electric locks are widely used in refrigerators, vending machines, express cabinets, luggage storage cabinets and other equipment due to their simple and convenient control. After the existing electric locks are unlocked, the door needs to be closed manually. For example, after most grid vending machines are unlocked, the door structure pops out as a whole and cannot automatically return to the closed state. It is not only not beautiful in public places, but also easy for mosquitoes and moths to fly in, causing dirt inside the cabinet and posing a safety hazard. When the cabinet is a refrigeration cabinet, if the cabinet door is always opened at an angle, it will cause cold air to leak out, the cooling effect will deteriorate, and the power consumption of the refrigerator will increase.
[0003] CN206667964U discloses an electric control lock for a vending machine, which is composed of an upper electric control lock, a lower electric control lock, an upper emergency unlocking device, a lower emergency unlocking device, an upper locking hook, and a lower locking hook. The door can be opened and closed remotely through a control password and a backstage, which facilitates the management of the vending machine. Although the electric control lock for the vending machine can be opened and closed through remote control, which greatly facilitates the opening and closing of the cabinet door, the operation process is relatively cumbersome, and there is still a problem of not closing the lock in time. Utility Model Content

[0010] The switch toggle member is connected to a reset member. When the pulling force on the magnet is greater than the magnetic attraction between the magnet and the switch toggle member, the magnet is separated from the switch toggle member, and the reset member controls the switch toggle member to reset.
[0011] Preferably, the reset member is an elastic member, and when the switch toggle member moves toward the door body, the elastic member is squeezed or stretched; when the magnet is separated from the switch toggle member, the switch toggle member is reset by the elastic force of the elastic member.
[0012] More preferably, the elastic member is a spring sleeved outside the switch toggle member, and the spring is compressed when the switch toggle member moves toward the door body.
[0013] Preferably, the switch comprises a micro switch, and when the switch toggle member is in the original position, it abuts against a spring of the micro switch, and the micro switch is in an off state;
[0014] When the switch toggle member moves toward the door body, the spring pops up and the micro switch is in a closed state.
[0015] Preferably, the control element comprises a solenoid valve.
[0016] More preferably, the locking tongue is a ratchet wheel that can rotate clockwise relative to the main body, and the ratchet wheel is provided with a limiting portion for limiting the position of the lock buckle;
[0017] The solenoid valve is connected to a limiter for limiting the rotation of the ratchet. When the solenoid valve controls the limiter to disengage from the ratchet, the ratchet rotates freely and is separated from the lock.

[0019] When the solenoid valve is powered on, the sliding rod of the solenoid valve pulls the locking rod to rotate in a direction away from the door body, the limiting hook is disengaged from the teeth on the ratchet, and the ratchet rotates and separates from the lock buckle.
[0020] Preferably, the pulling member is in the form of a handle, and the handle is provided with an upper and a lower pull rod, and the two pull rods respectively penetrate the door body and are connected to the magnet.
[0021] Preferably, a mounting seat is provided at the end of the pull rod, and the magnet is fixed on the mounting seat.
[0022] More preferably, a return spring is disposed outside the pull rod, and two ends of the return spring abut against the door body and the mounting seat respectively.
[0023] The technical solution claimed in the present disclosure has achieved the following beneficial effects:
[0024] 1) The lock is unlocked by magnetic triggering, so the solenoid valve does not need to work for a long time, which reduces power consumption, has a simple structure and high cost performance.
[0025] 2) After the door is opened, due to the magnetic attraction between the magnet and the switch toggling member, the door can be automatically locked only by relying on the gravity of the door body itself or applying a slight force to the door body. The locking is timely and convenient, ensuring the airtightness of the cabinet body and avoiding problems such as cold air leakage and cabinet interior hygiene caused by the door being open for a long time.
[0026] 3) Due to the magnetic attraction trigger being adopted, compared with the existing electric control locks, the electric control lock in the present disclosure is more suitable for application to cabinet doors with large volume and large weight, such as cold cabinet doors.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0032] In order to make the objectives, technical solutions, and beneficial effects in the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.
[0033] Refer to the attached Figure 1 and 2, this embodiment provides an electric control lock, including an electric control lock main body 1 arranged inside the door body 11, and the electric control lock main body is fixedly installed through a mounting panel 7. The inside of the main body 1 includes a switch 3, a switch toggling member 4, a control member 2, and a lock tongue 13. The door body 11 is provided with a pulling member 10 penetrating through the door body, and the end of the pulling member 10 located inside the door body 11 is connected to a magnet 8. Among them, the magnetic sticker 8 is selected as a strong magnet, such as a neodymium iron boron magnet.
[0034] The switch toggling member 4 is magnetically attracted to the magnet 8 and is used to toggle the switch 3; when the pulling member 10 is pulled, due to the magnetic attraction, the switch toggling member 4 moves a certain distance along with the pulling member 10 and toggles the switch 3 to close.
[0035] The switch 3 is used to control the power-on or power-off of the control member 2. The control member 2 is connected to the lock tongue 13 and is used to control the separation of the lock tongue 13 from the lock catch 12. The lock catch 12 is arranged on the door body 11. The switch toggling member 4 is connected to a reset member 6. When the pulling force on the magnet 8 is greater than the magnetic attraction force between the magnet 8 and the switch toggling member 4, the magnet 8 is separated from the switch toggling member 4, and the reset member 6 controls the switch toggling member 4 to reset.
[0036] In the solution of this embodiment, the solenoid valve is triggered by combining the pulling member 10 with magnetic attraction, so the solenoid valve does not need to work for a long time, reducing power consumption, having a simple structure and high cost performance.
[0037] After the door is opened, due to the magnetic attraction force between the magnet and the switch toggling member, and the locking force of the ratchet-type lock tongue is very small, so only relying on the gravity of the door body itself or applying a slight force to the door body can make the door automatically lock. The door locks in a timely and convenient manner, ensuring the airtightness of the cabinet body and avoiding problems such as cold air leakage and cabinet interior hygiene caused by the door being opened for a long time.
[0038] In addition, due to the adoption of magnetic attraction triggering, compared with the existing locks, the electric control lock in this embodiment is more suitable for application to large-volume and heavy cabinet doors, such as cold cabinet doors, etc.
[0039] In the preferred solution, the reset member 6 is an elastic member. When the switch toggling member 4 moves towards the door body 11, the elastic member is compressed or stretched; when the magnet 8 is separated from the switch toggling member 4, the switch toggling member 4 is reset by the elastic force of the elastic member. In an exemplary structure, the elastic member is a spring sleeved outside the switch toggling member 4. When the switch toggling member 4 moves towards the door body 11, the spring is compressed, and this spring is fixed by a circlip 5 and is located between the circlip 5 and the mounting panel 7.
[0040] In a preferred embodiment, the switch 3 includes a micro switch, which is connected to the main board connection harness 18 of the electric lock. When the switch toggle member 4 is in the original position, it contacts the spring of the micro switch, and the micro switch is in the open state; when the switch toggle member 4 moves toward the door body 11, the spring pops up, and the micro switch is in the closed state.
[0041] In a preferred solution, the control member 2 can be set as a solenoid valve. The lock tongue 13 is a ratchet that can rotate clockwise relative to the main body, and the ratchet is provided with a limiting portion for limiting the lock buckle 12. The solenoid valve is connected to a limiting member 14 for limiting the rotation of the ratchet, and when the solenoid valve controls the limiting member 14 to disengage from the ratchet, the ratchet rotates freely and separates from the lock buckle 12 to achieve unlocking.
[0042] In an exemplary structure, the limiter includes a long strip locking rod, one end of which is rotatably connected to the main body via a rotating shaft, and is provided with a limit hook that engages with the teeth on the ratchet. When the solenoid valve is energized, the slide rod 15 of the solenoid valve pulls the locking rod to rotate in a direction away from the door body 11, the limit hook disengages from the teeth on the ratchet, and the ratchet rotates and separates from the lock buckle 12. The slide rod 15 is provided with a solenoid valve reset spring 16. In addition, the design of the long strip locking rod and the ratchet cycle lock tongue can achieve unobstructed locking at any angle.
[0043] In the exemplary structure, the pull member 10 is in the form of a handle, and the handle is provided with an upper and lower pull rod, and the two pull rods respectively penetrate the door body 11 and are connected to the magnet 8. In the preferred solution, a mounting seat 9 is provided at the end of the pull rod, and the magnet 8 is fixed on the mounting seat 9. In addition, a handle reset spring 17 is provided outside the pull rod, and the two ends of the reset spring respectively abut against the door body 11 and the mounting seat 9.
[0044] The process of unlocking and locking the electric control lock in this embodiment is as follows:
[0045] When the handle is pulled, the handle drives the two pull rods to move toward the outside of the door. Due to the magnetic attraction of the magnet at the end of the pull rod, the switch toggle also moves toward the outside of the door with the handle and compresses the spring mounted on it. As the switch toggle moves, the spring of the micro switch that was originally pressed by the switch toggle bounces up, the micro switch closes, and the solenoid valve is energized.
[0046] After the solenoid valve is energized, the iron core slide rod is attracted away from the door body, driving the limiter to move away from the door body. At this time, the limiter rotates clockwise, and the limit hook on it disengages from the teeth on the ratchet. At this time, the ratchet can rotate freely in the clockwise direction and separate from the lock buckle, realizing unlocking and opening the door.
[0047] After the door is opened to a certain extent, the pulling force on the magnet is greater than the magnetic attraction force between the magnet and the switch toggle, at which time the magnet is separated from the switch toggle. The switch toggle is reset under the action of the elastic force of the spring sleeved thereon, and presses the elastic piece of the micro switch again. The solenoid valve is powered off, and the limiting member also returns to its original locked limiting position.
[0048] When the electric control lock in this embodiment is applied to a cabinet with an up-and-down opening door, after taking out the items, under the influence of the door gravity and magnetic attraction, the lock tongue and the lock buckle will be automatically locked.
[0049] When the electric control lock in this embodiment is applied to a cabinet with a left-and-right opening door, due to the magnetic attraction, after use, only a slight force needs to be applied to the door body to lock the lock tongue and the lock buckle.
[0050] The embodiments described above are only exemplary descriptions of the present disclosure, and do not limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present disclosure shall fall within the protection scope determined by the present disclosure.
