Description

Technical Field

[0001] This utility model relates to a lock, and more particularly to a assisted magnetic lock box. Background Technology

[0002] There are now many types of locks, and their functionality is becoming increasingly sophisticated. Magnetic locks are one such type. Currently, magnetic locks on the market typically have magnets installed in the strike box. After the bolt extends into the strike box, the magnetic attraction between the magnet and the bolt is used to achieve the locking purpose (e.g., patent: CN202321601096, patent name: strike box and magnetic lock including the strike box).

[0003] However, due to the strong magnetic force, when opening the door, if it is a manual door lock, the user needs to manually turn the door handle forcefully to disengage the bolt from the strike box, resulting in a poor user experience; if it is an electronic fully automatic door lock, a high-power motor is required to drive the bolt out of the strike box, resulting in high motor power consumption and high cost.

[0004] Therefore, the applicant designed an assisted magnetic lock box to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an assisted magnetic lock box.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A assisted magnetic lock box includes a lock box and a magnet installed inside the lock box, characterized in that: the lock box is provided with an assisted elastic element that can press against the lock tongue.

[0008] The assisting elastic element is a compression spring.

[0009] It also includes the power-assisted decorative panel, which is connected to the latch box via a guide limiting structure. One end of the compression spring abuts against the power-assisted decorative panel, and the other end of the compression spring abuts against the latch box. The power-assisted decorative panel can move within the latch box by being pushed by the compression spring, and the latch can press against the power-assisted decorative panel.

[0010] The guide limiting structure includes a limiting groove disposed on the inner side wall of the lock box and a guide limiting hook disposed on the auxiliary decorative plate, wherein the hook part of the guide limiting hook is located in the limiting groove.

[0011] The locking box includes a locking box panel, an inner box body, and a locking box fixing frame. The inner box body and the locking box panel are both connected and fixed to the locking box fixing frame. The magnet is located between the inner box body and the locking box fixing frame. The locking box panel is provided with a panel hole.

[0012] The buckle box fixing frame includes a U-shaped main frame and connecting foot plates disposed opposite to each other at both ends of the main frame. The buckle box panel is fixed to the connecting foot plates, and the inner box is located in the main frame.

[0013] The bottom surface of the inner box is provided with a receiving hole, the magnet is located in the receiving hole, and the receiving hole is closed by a buckle fixing bracket.

[0014] Several positioning plates are arranged opposite each other on the side wall of the receiving hole, and the magnet is located between the positioning plates.

[0015] The magnet is square.

[0016] The outer surface of the inner box is provided with positioning protrusions, and the main frame is locked between the positioning protrusions.

[0017] The beneficial effects of this utility model are as follows: This utility model includes a latch box and a magnet installed inside the latch box. The latch box is provided with an assisting elastic element that can press against the bolt. The above structure does not affect the attraction between the bolt and the magnet when locked. When unlocking, the pushing force of the assisting elastic element on the bolt offsets part of the magnetic force of the magnet on the bolt, thereby reducing the pulling force required for unlocking. Therefore, manual unlocking does not require vigorous turning of the handle; when automatically unlocking, the power requirement of the motor is also reduced, thus reducing costs.

However, this disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Furthermore, this disclosure is limited only by the scope of the claims.

[0023] The shapes, dimensions, scales, angles, and numbers disclosed in the accompanying drawings used to describe embodiments of this disclosure are merely examples, and therefore this disclosure is not limited to the details shown. Throughout this specification, the same reference numerals refer to the same elements. In the following description, detailed descriptions of relevant known functions or configurations will be omitted where it is determined that such detailed descriptions would unnecessarily obscure the focus of this disclosure. Where the terms “comprising,” “having,” and “including” are used in this specification, additional components may be added unless “only” is used. Unless otherwise indicated, singular terms may include plural forms.

[0024] When interpreting components, even if not explicitly described, the components are understood to include a range of tolerances.

For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this disclosure.

[0028] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0029] Reference Figures 1 to 3This utility model discloses an assisted magnetic lock box, including a lock box 1 and a magnet 2 installed inside the lock box 1. The lock box 1 is provided with an assisted elastic element 3 that can press against the bolt. When unlocking, the elastic force of the assisted elastic element 3 pushes the bolt back, thereby reducing the pulling force required for unlocking. Of course, the elastic force of the assisted elastic element 3 is definitely less than the magnetic attraction force of the magnet 2 on the bolt, thus ensuring that the magnet 2 and the bolt are attracted to each other and locked. The applicant has also verified this on electronic fully automatic door locks. In the old structure without the assisted elastic element 3, the motor could not drive the bolt back when the motor voltage was 5V. However, after adding the assisted elastic element 3, even when the motor voltage dropped to 3.6V, and the electronic fully automatic door lock issued a low power alarm signal, the motor was still able to drive the bolt back. From the above, it can be seen that the assisted elastic element 3 has a huge assisting effect on electronic fully automatic door locks.

[0030] Preferably, the assisting elastic element 3 is a compression spring. The above is only a preferred option and does not constitute a limitation of this application. Of course, we can also use a torsion spring or set an elastic metal sheet to achieve the purpose of elastic force pushing the lock tongue to retract.

[0031] As shown in the figure, the system also includes the auxiliary decorative plate 4, which is connected to the latch box 1 via a guide limiting structure. One end of the compression spring abuts against the auxiliary decorative plate 4, and the other end of the compression spring abuts against the latch box 1. The auxiliary decorative plate 4 can move within the latch box 1 by the push of the compression spring. The latch can press against the auxiliary decorative plate 4. The auxiliary decorative plate 4 is slightly smaller than the opening of the latch box 1, which can close the opening. This way, the compression spring is not visible from the outside, making the overall appearance more aesthetically pleasing. Moreover, the compression spring has a spiral structure with one coil after another, and the contact surface with the latch is small, making it prone to deflection and slippage. Therefore, by using the auxiliary decorative plate 4 to contact the latch, the contact surface is large and stable, and the precision requirements for the latch position are also lower. As a further structure, the guide limiting structure includes a limiting groove 5 disposed opposite to the inner side wall of the latch box 1 and a guide limiting hook 6 disposed opposite to the auxiliary decorative plate 4. The hook part 7 of the guide limiting hook 6 is located in the limiting groove 5. When the auxiliary decorative plate 4 is located at the box opening, the hook part 7 can abut against the end wall of the limiting groove 5, thereby preventing the auxiliary decorative plate 4 from being pushed out of the box opening by the compression spring. The above structure is simple, and the auxiliary decorative plate 4 and the guide limiting hook 6 can be integrally formed by punching.

[0032] As shown in the figure, the locking box 1 includes a locking box panel 8, an inner box body 9, and a locking box fixing frame 10. The limiting groove 5 is specifically located on the side wall of the inner box body 9. The compression spring is also located in the inner box body 9 and abuts against the bottom surface of the inner box body 9. The locking box panel 8 is connected and fixed to the locking box fixing frame 10. The magnet 2 is located between the inner box body 9 and the locking box fixing frame 10. The locking box panel 8 has a panel hole 11, which overlaps with the box opening. The opening of the inner box body 9 communicates with the panel hole 11. This structure facilitates manufacturing and assembly. When the locking box panel 8 and the locking box fixing frame 10 are connected and fixed, the inner box body 9 can be positioned between them, thus simplifying assembly. As a further structural feature, the snap-fit ​​box fixing bracket 10 includes a U-shaped main frame 12 and connecting foot plates 13 disposed opposite to both ends of the main frame 12. The snap-fit ​​box panel 8 is fixed to the connecting foot plates 13, and the inner box 9 is located within the main frame 12. The U-shaped main frame 12 is recessed to form a mounting groove, in which the inner box 9 is fitted. As a further structural feature, the outer surface of the inner box 9 is provided with positioning protrusions 14, and the main frame 12 is fitted between the positioning protrusions 14. Thus, the main frame 12 and the inner box 9 form a mutually interlocking structure. By tightening the snap-fit ​​box panel 8 and the snap-fit ​​box fixing bracket 10 with screws, the snap-fit ​​box panel 8, the inner box 9, and the snap-fit ​​box fixing bracket 10 can be fixed as a whole. Of course, the snap-fit ​​box panel 8 is provided with connecting holes for fixing the snap-fit ​​box 1 to the door frame.

[0033] As shown in the figure, the bottom surface of the inner box 9 is provided with a receiving hole 15, and the magnet 2 is located in the receiving hole 15. The receiving hole 15 is closed by the snap-fit ​​bracket 10. The above structure not only hides the magnet 2 in the snap-fit ​​box 1, but also achieves the fixation of the magnet 2 by using the snap-fit ​​panel 8, the inner box 9, and the snap-fit ​​bracket 10, reducing the assembly process and simplifying the structure. As a further structure, several positioning plates 16 are provided on the side wall of the receiving hole 15. The magnet 2 is located between the positioning plates 16. The positioning plates 16 restrict the position of the magnet 2, and the positioning plates 16 only have narrow end faces that contact and position the magnet 2. Therefore, the contact area is small, and when the magnet 2 needs to be snapped out of the receiving hole 15, there is not only operating space but also little friction, making it easier.

[0034] As shown in the figure, the magnet 2 is square, so the end face of the lock tongue is also square. Therefore, the two shapes correspond to each other, and square is also a simple shape that is easy to manufacture and process.

[0035] The above provides a detailed description of the assisted magnetic lock box provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
