Description

Technical Field

[0001] The utility model relates to the field of locks, in particular to a cathode lock. Background Art

[0002] Existing traditional locks have a relatively simple structure and cannot be designed with external switch control. Replacing the entire lock is relatively expensive. However, if only the part connected to the door frame is replaced, the external switch control design can be implemented at the lowest cost.

[0003] Among existing patents, reference is made to patent CN106088840B, which discloses a cathode lock that uses an electromagnet to control the operation of a second hinged shaft within the lock bolt assembly, thereby achieving unlocking and unlocking through the lock bolt assembly cooperating with the lock bolt on the other side of the lock body. However, in the existing design, the mode switching structure of this product, that is, the adjustment member, is located behind the cathode lock. In actual use, if you want to switch modes, you need to remove the entire cathode lock from the door frame to switch modes, which brings inconvenience.

[0004] Therefore, there is a need for a cathode lock that can adjust the structural design inside the cathode lock so that the adjustment paddle is arranged on the outside of the cathode lock and the working mode of the cathode lock can be easily adjusted. Utility Model Content

[0005] The main purpose of the utility model is to provide a cathode lock which can conveniently adjust the working mode of the cathode lock by adjusting the structural design inside the cathode lock so as to arrange the adjusting paddle on the outside of the cathode lock.

[0006] The utility model provides a cathode lock, comprising a lock housing, an electromagnet, a lock tongue assembly, a pushing member, a limiting member and a toggle member;

[0007] The lock housing is provided with a lock housing connection hole at the front end, the two sides of the lock tongue assembly are rotatably connected to the lock housing connection hole, the pushing member is rotatably connected to the rear side of the lock tongue assembly, and the electromagnet is provided at the bottom of the pushing member, and the pushing member can be driven by the electromagnet to move, thereby limiting or releasing the limit of the lock tongue assembly through the pushing member;

[0008] The limiting member is arranged on one side of the pushing member, and the pushing member can be limited by the limiting member. A toggle hole is provided at the bottom of the lock tongue assembly. The toggle member is rotatably connected in the lock housing and one end extends from the toggle hole. The limiting member can be driven to move by the toggle member, and the pushing member can be locked or unlocked by the limiting member.

[0009] Preferably, the lock housing includes a base and an outer cover, and downwardly bent connecting protrusions are provided on both sides of the outer cover. The connecting protrusions and the sides of the base are connected by screws, so that the outer cover is connected to the base.

[0010] Preferably, the lock case also includes a connecting plate, a base front connecting hole is provided on the front side of the base, and a connecting plate first connecting hole is provided on the connecting plate corresponding to the base front connecting hole, and the connecting plate first connecting hole and the base front connecting hole are matched to connect the connecting plate to the front side of the base.

[0011] Preferably, second connecting holes are provided on both ends of the connecting plate, and the connecting plate can be connected to the door frame through the second connecting holes, thereby connecting the cathode lock to the door frame.

[0012] Preferably, a first return spring is provided between the pushing member and the inner side wall of the lock housing.

[0013] Preferably, a second return spring is provided between the limiting member and the inner side wall of the lock housing.

[0014] Preferably, it also includes an electrical connection seat, a base electrical connection hole is provided on the side of the base, an internal connection groove is provided in the electrical connection hole, and the electrical connection seat is provided with a side connection block, and the side connection block and the internal connection groove are matched to clamp the electrical connection seat in the base.

[0016] The beneficial effects of the cathode lock of the utility model are:

[0017] 1. By setting a toggle hole on the front side of the lock housing and setting a toggle piece in the toggle hole, the cathode lock can adjust the working mode from the front side, which effectively improves the user experience compared to the existing design.

[0018] 2. By setting a limiter and a toggle member, the state of the limiter can be adjusted by the toggle member, thereby controlling the state of the pusher, thereby realizing the switching of the cathode lock working mode. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Reference Figures 1 to 6 , an embodiment of the cathode lock of the utility model is proposed:

[0029] A cathode lock comprises a lock housing 1, an electromagnet 5, a lock tongue assembly 2, a pusher 6, an electrical connection seat 4, a limiter 7 and a toggle member 3.

[0030] The lock case 1 comprises a base 11, an outer cover 12, and a connecting plate 13. Downward-bent connecting protrusions are provided on both sides of the outer cover 12. These protrusions are screwed to the sides of the base 11, thereby securing the outer cover 12 to the base 11. A front connecting hole 111 is provided on the front side of the base 11. The connecting plate 13 has first connecting holes 131 corresponding to these holes. These first connecting holes 131 engage with the front connecting holes 111, securing the connecting plate 13 to the front side of the base 11. Second connecting holes 132 are also provided at both ends of the connecting plate 13. These second connecting holes 132 allow the connecting plate 13 to be attached to the door frame, thereby connecting the cathode lock to the door frame.

[0031] The base 11 has an electrical connection hole on its side, an internal connection slot within the hole, and a side connection block on the electrical connector 4. The side connection block engages with the internal connection slot to secure the electrical connector 4 within the base 11. The electrical connector 4 has two electrical connectors 41, one for each external circuit, through which the electrical connector 4 is connected to the external circuit.

[0032] The front end of the base 11 is provided with a lock housing connection hole, to which both sides of the lock housing assembly 2 are pivotally connected. A pusher 6 is pivotally connected to the rear side of the bolt assembly 2 at one end. A first return spring 61 is provided between the pusher 6 and the inner sidewall of the lock housing 1, enabling the pusher 6 to reset. An electromagnet 5 is provided at the bottom of the pusher 6, which can drive the pusher 6 to move, thereby restraining or releasing the bolt assembly 2.

[0033] The limiting member 7 is rotatably connected to one side of the push member 6 and can limit the push member 6 through the limiting member 7. A second return spring 71 is provided between the limiting member 7 and the inner wall of the lock housing 1. A toggle hole 112 is provided at the bottom of the lock bolt assembly 2. The toggle member 3 is rotatably connected to the lock housing 1 with one end extending from the toggle hole 112. The toggle member 3 can drive the limiting member 7 to move, thereby locking or unlocking the push member 6 through the limiting member 7.

[0034] When in use, there are two working modes. In the first working mode, the toggle member 3 is toggled to lock the limit member 7. At this time, the limit member 7 cannot affect the push member 6. At this time, the electromagnet 5 and the lock tongue assembly 2 can work normally.

[0035] The second working mode is to cancel the locking of the limit member 7 by toggling the toggle member 3. At this time, the limit member 7 limits the push member 6. At this time, the push member 6 cannot affect the lock tongue assembly 21, and the electromagnet 5 cannot act on the lock tongue assembly.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
