Description

Technical Field

[0001] This utility model relates to the field of locks, and more specifically, to an electric lock. Background Technology

[0002] In the lock industry, some electric locks require the latch to remain extended from the lock body. Unlocking is achieved by lifting the handle from the inside or outside of the door to retract the latch into the lock body. Existing locks of this type often have complex latch transmission mechanisms, requiring multi-stage linkages or gear structures to transmit power from the handle to the latch. This complex structure results in numerous internal parts, a crowded layout, inconvenient assembly, and low force transmission efficiency. Users experience significant resistance and a stiff feel when operating the handle, and the latch retraction is delayed and prone to jamming, affecting the smoothness of the unlocking experience. Utility Model Content

[0003] The purpose of this utility model is to provide an electric lock with a simple and compact structure, efficient transmission, and the ability to effectively improve the smoothness of operation and user experience.

[0004] An electric lock includes a housing, a square latch assembly and a bevel latch assembly disposed within the housing, the bevel latch assembly including a handle lever, a bevel latch lever and a bevel latch, the handle lever having a first lever, the bevel latch lever having a second lever abutting against the first lever, and a traction arm connected to the bevel latch; The handle lever can rotate under the action of external force, and pushes the second lever through the first lever, which drives the tongue lever to rotate, and then drives the tongue to slide through the traction arm.

[0005] In the above technical solution, when the user operates the handle, external force drives the handle lever to rotate. The first lever on the handle then pushes the second lever of the latch lever, which abuts against it, effectively transmitting the rotational motion to the latch lever. When the latch lever rotates, it directly drives the latch to slide via its traction arm. The entire transmission structure consists of two core components: the handle lever and the latch lever. This makes the overall structure more compact, saving internal installation space in the lock, while ensuring effective force transmission. It achieves a fast and reliable response from the latch, effectively improving operational smoothness and user experience.

[0006] Furthermore, the oblique tongue includes an oblique tongue body, a connecting rod, an oblique tongue return spring, and a sliding plate. The oblique tongue body and the sliding plate are respectively disposed at both ends of the connecting rod. The oblique tongue return spring is sleeved on the outer periphery of the connecting rod, and the traction arm abuts against the sliding plate.

[0007] In the above technical solution, the latch includes a latch body, a connecting rod, a sliding plate, and a latch return spring sleeved on the connecting rod. The connecting rod enables the latch body and the sliding plate to move synchronously. The traction arm drives the latch body to slide through the sliding plate, making the entire latch assembly more compact and the movement process more stable. The latch return spring provides a return force for the latch, ensuring that the latch can automatically and smoothly return to its original position after the loss of external force.

[0008] Furthermore, the outer casing is provided with a slanted tongue guide groove, and the sliding plate has a flange that extends into the slanted tongue guide groove.

[0009] In the above technical solution, by setting a guide groove for the oblique tongue on the outer shell, the sliding plate cooperates with the guide groove for the oblique tongue through the flange, which provides guidance for the sliding of the oblique tongue, effectively preventing the oblique tongue from deflecting or getting stuck during the sliding process, and ensuring the stability of its movement.

[0010] Furthermore, the square tongue assembly includes a square tongue, a square tongue paddle, a driving member, and a transmission gear. The driving member is connected to the transmission gear, and the square tongue paddle has a third lever that is pulsatorically connected to the square tongue. The driving member can drive the square tongue paddle to rotate through the transmission gear and drive the square tongue to slide through the third lever.

[0011] In the above technical solution, by using a driving component combined with a transmission gear to drive the square tongue paddle, and then controlling the extension and retraction of the square tongue through a third lever, the transmission structure is simple and efficient, ensuring the reliability and stability of power transmission.

[0012] Furthermore, the square tongue includes a square tongue body and a plate, the plate having a square tongue guide groove, and the outer shell having a guide post passing through the square tongue guide groove.

[0013] In the above technical solution, by opening a guide groove on the plate of the square tongue and cooperating with the guide post on the outer shell, a reliable guide is provided for the extension and retraction movement of the square tongue, making the movement of the square tongue more stable and accurate.

[0014] Furthermore, the guide post is fitted with a torsion spring, which is connected to the third lever.

[0015] In the above technical solution, a torsion spring connected to the third lever is installed on the guide post, which provides assistance for the extension of the square tongue body, enabling the square tongue to extend more quickly, thereby reducing the load on the driving component.

[0016] Furthermore, the handle lever includes a limiting lever. When the square tongue is extended, the third lever abuts against the limiting lever to restrict the rotation of the handle lever.

[0017] In the above technical solution, by setting a limiting lever integrated with the handle lever, it abuts against the third lever of the handle lever when the latch extends, thereby preventing the handle lever from rotating when the latch extends, thus enhancing the security and reliability of the lock after locking.

[0018] Furthermore, it also includes a status sensing component, which includes a sensing tongue, a sensing tongue return spring, and a sensing switch. The sensing tongue return spring is connected to the sensing tongue, and the sensing tongue has a rod body opposite to the sensing switch. When the sensing tongue is extended, the rod body abuts against the sensing switch.

[0019] In the above technical solution, by setting a status sensing component, the sensing tongue can automatically extend out of the lock body under the action of elasticity after the door is opened, so that the rod body contacts the sensor switch. After the door is closed, the sensing tongue retracts into the lock body, at which time the rod body separates from the sensor switch, thereby enabling accurate and real-time detection and feedback of the door's open / closed status.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: When the user operates the handle, external force drives the handle lever to rotate, and the first lever on it then pushes the second lever of the latch lever that abuts against it, thereby effectively transmitting the rotational motion to the latch lever. When the latch lever rotates, it directly drives the latch to slide through the traction arm on it. The entire transmission structure consists of two core components: the handle lever and the latch lever, making the overall structure more compact, saving installation space inside the lock, while ensuring that the force can be effectively transmitted, achieving a fast and reliable response of the latch, and effectively improving the smoothness of operation and the user experience.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] Please refer to Figures 1 to 4 In a preferred embodiment, the normally open electric lock with a slanted latch 33 of this invention mainly includes a housing 1, a square latch assembly 2 and a slanted latch assembly 3 disposed within the housing 1. The slanted latch assembly 3 includes a handle lever 31, a slanted latch lever 32, and a slanted latch 33. The handle lever 31 has a first lever 311, and the slanted latch lever 32 has a second lever 321 that abuts against the first lever 311, and a traction arm 322 connected to the slanted latch 33. The handle lever 31 can rotate under external force, and pushes the second lever 321 through the first lever 311, causing the slanted latch lever 32 to rotate, which in turn drives the slanted latch 33 to slide through the traction arm 322.

[0029] For example, the handle lever 31 is rotatably mounted inside the housing 1, and has a square hole at its center for connecting a handle (not shown). The handle lever 31 can be driven to rotate by the handle. The latch lever 32 is rotatably mounted inside the housing 1, and its outer periphery extends outward to form a second lever 321 and a traction arm 322. The traction arm 322 is connected to the latch 33. The outer periphery of the handle lever 31 extends outward to form a first lever 311, which abuts against the second lever 321. When the user operates the handle, an external force drives the handle lever 31 to rotate. The first lever 311 on it then pushes the second lever 321 of the latch lever 32, thereby effectively transmitting the rotational motion to the latch lever 32. When the latch lever 32 rotates, it directly drives the latch 33 to slide through the traction arm 322. The entire transmission structure consists of two core components: the handle lever 31 and the latch lever 32. This makes the overall structure more compact, saves installation space inside the lock, and ensures that the force can be effectively transmitted. It also enables the latch 33 to respond quickly and reliably, effectively improving the smoothness of operation and the user experience.

[0030] Please refer to Figure 2 The oblique tongue 33 includes an oblique tongue body 331, a connecting rod 332, an oblique tongue return spring 333, and a sliding plate 334. The oblique tongue body 331 and the sliding plate 334 are respectively located at both ends of the connecting rod 332. The oblique tongue return spring 333 is sleeved on the outer periphery of the connecting rod 332, and the traction arm 322 abuts against the sliding plate 334. The oblique tongue 33 includes an oblique tongue body 331, a connecting rod 332, a sliding plate 334, and an oblique tongue return spring 333 sleeved on the connecting rod 332. The connecting rod 332 enables the oblique tongue body 331 and the sliding plate 334 to move synchronously. The traction arm 322 drives the oblique tongue body 331 to slide through the sliding plate 334, making the structure of the entire oblique tongue assembly 3 more compact and the movement process more stable. The oblique tongue return spring 333 provides a return force for the oblique tongue 33, ensuring that the oblique tongue 33 can automatically and smoothly return to its original position after the loss of external force.

[0031] In this embodiment, the outer casing 1 is provided with a guide groove 11 for the oblique tongue 33, and the sliding plate 334 has a flange 335 that extends into the guide groove 11 for the oblique tongue 33. Specifically, the outer casing 1 is provided with two guide grooves 11 for the oblique tongue 33, which are arranged opposite to each other and parallel to the axial direction of the connecting rod 332. Both ends of the sliding plate 334 are provided with flanges 335, each flange 335 extending into the guide groove 11 for the oblique tongue 33 on the corresponding side, thereby guiding the sliding of the oblique tongue 33. By providing guide grooves 11 for the oblique tongue 33 on the outer casing 1, the sliding plate 334, through the cooperation of the flange 335 with the guide groove 11 for the oblique tongue 33, provides guidance for the sliding of the oblique tongue 33, effectively preventing the oblique tongue 33 from deflecting or getting stuck during the sliding process, and ensuring the stability of its movement.

[0032] Please refer to Figure 3 The square tongue assembly 2 includes a square tongue 21, a square tongue paddle 22, a driving member 23, and a transmission gear 24. The driving member 23 is connected to the transmission gear 24. The square tongue paddle 22 has a third lever 221 that is pulsatorically connected to the square tongue 21. The driving member 23 can drive the square tongue paddle 22 to rotate via the transmission gear 24 and drive the square tongue 21 to slide via the third lever 221. For example, the driving member 23 can be a motor, the output end of which meshes with the transmission gear 24. The transmission gear 24 is coaxially arranged with the square tongue paddle 22. By using the driving member 23 in conjunction with the transmission gear 24 to drive the square tongue paddle 22, and then controlling the extension and retraction of the square tongue 21 via the third lever 221, the transmission structure is simple and efficient, ensuring reliable and stable power transmission.

[0033] In this embodiment, the square tongue 21 includes a square tongue body 211 and a plate 212. A square tongue guide groove 213 is provided on the plate 212, and a guide post 12 passing through the square tongue guide groove 213 is provided on the outer shell 1. The length direction of the square tongue guide groove 213 is parallel to the sliding direction of the square tongue 21. By providing a guide groove on the plate 212 of the square tongue 21 and cooperating with the guide post 12 on the outer shell 1, a reliable guide is provided for the telescopic movement of the square tongue 21, making the movement of the square tongue 21 more stable and accurate.

[0034] In this embodiment, the plate 212 is provided with a drive groove at one end near the square tongue lever 22. The third lever 221 extends into the drive groove. When the square tongue lever 22 rotates in a clockwise or counterclockwise direction, the third lever 221 pushes the groove walls on both sides of the drive groove, thereby driving the square tongue body 211 to move.

[0035] A torsion spring 25 is fitted onto the guide post 12, and the torsion spring 25 is connected to the third lever 221. The torsion spring 25 connected to the third lever 221 on the guide post 12 provides assistance for the extension of the square tongue body 211, so that the square tongue 21 can extend more quickly, thereby reducing the load on the drive component 23.

[0036] Please refer to this again. Figure 2 The handle lever 31 includes a limiting lever 312. When the latch 21 extends, the third lever 221 abuts against the limiting lever 312 to restrict the rotation of the handle lever 31. By providing a limiting lever 312 integrated with the handle lever 31, which abuts against the third lever 221 of the latch lever 22 when the latch 21 extends, the rotation of the handle lever 31 is prevented when the latch 21 extends, thereby enhancing the security and reliability of the lock after locking.

[0037] The normally open electric lock with a slanted latch 33 of this utility model also includes a status sensing component 4. The status sensing component 4 includes a sensing latch 41, a sensing latch return spring 42, and a sensing switch 43. The sensing latch return spring 42 is connected to the sensing latch 41. The sensing latch 41 has a rod 44 opposite to the sensing switch 43. When the sensing latch 41 extends, the rod 44 abuts against the sensing switch 43. By setting the status sensing component 4, the sensing latch 41 can automatically extend out of the lock body under the action of spring force after the door is opened, so that the rod 44 contacts the sensing switch 43. After the door is closed, the sensing latch 41 retracts into the lock body. At this time, the rod 44 separates from the sensing switch 43, thereby enabling accurate and real-time detection and feedback of the door's open / closed status.
