Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a magnetic safety lock for a display case glass door. Background Technology

[0002] A display case glass door is a door component used in display cases. It is usually made of transparent glass, which has good light transmission and display effect, allowing viewers to clearly see the exhibits inside the display case. It not only protects the exhibits and prevents dust and external interference, but also enhances the overall aesthetics and professionalism of the display case through its exquisite design and high-quality materials.

[0003] The glass doors of the display cases are locked using magnetic locks. These locks remain powered after the door is closed to maintain the magnetic attraction, ensuring the door is securely locked. Through the principle of magnetic attraction, magnetic locks not only reliably lock the door but can also be easily opened when needed, offering both high security and concealment. Their outer shells are typically made of wear-resistant and rust-proof materials, making them highly durable. Furthermore, the key cross-keying rate of magnetic locks is extremely low, with some high-end products even achieving a cross-keying rate of 1 in 1.3 billion, greatly reducing the risk of accidental opening and effectively preventing theft of exhibits, providing reliable protection for the exhibits inside the display cases.

[0004] In current magnetic lock technology, many key structural components are designed on the outside of the lock body. While this design simplifies the installation and maintenance process and reduces operational complexity to some extent, it introduces some significant safety hazards. Magnetic attraction is essentially a physical attraction force, and compared with traditional mechanical locking devices, it cannot provide the same reliable locking effect. In scenarios with extremely high security requirements, such as when important cultural relics are stored in display cases, relying solely on magnetic attraction to achieve locking is clearly insufficient to meet security needs, and the safety of the cultural relics may be threatened. Therefore, a magnetic safety lock for display case glass doors is proposed to address the above issues. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-7 This utility model provides a technical solution:

[0030] A magnetic safety lock for a display case glass door includes a display case body 1 and a glass door 2. A magnetic fixing component 3 is fixedly connected to the inside of the display case body 1. A frame component 4 is fixedly connected to the left side of the glass door 2. A locking component 5 is installed inside the frame component 4. The frame component 4 includes a fixing plate 41. A horizontal plate 42 is fixedly connected to the left side of the fixing plate 41. A boss 43 is fixedly connected to both the upper and lower ends of the horizontal plate 42. A shaft hole 44 is opened inside the boss 43. A spring 45 is fixedly connected to the inside of the shaft hole 44. A baffle 46 is fixedly connected to the left end of the horizontal plate 42. The locking component 5 includes a locking plate 51. A permanent magnet block 52 is fixedly connected to the top of the locking plate 51. An inclined fixing plate 53 is fixedly connected to the lower end of the locking plate 51. A rack 54 is fixedly connected to the outside of the inclined fixing plate 53. A shaft column 55 is fixedly connected to both the front and rear ends of the inclined fixing plate 53. The shaft column 55 is rotatably connected to the inside of the boss 43.

[0031] As a further implementation of this solution, the right end of the display cabinet body 1 is rotatably connected to the glass door 2 via a hinge, the inner side of the display cabinet body 1 is fixedly connected to the fixed base 31, and the left side of the glass door 2 is fixedly connected to the fixed plate 41. Through the above settings, the smooth opening and closing of the door is achieved, providing a basis for the locking component 5 to be locked inside the magnetic fixing component 3.

[0032] As a further implementation of this solution, the magnetic fixing component 3 includes a fixing base 31, with a fixing housing 32 fixedly connected to the bottom of the fixing base 31. A receiving groove 33 is provided on the inner side of the fixing housing 32, and an electromagnet 34 is fixedly connected to the upper end of the receiving groove 33. The right end of the receiving groove 33 penetrates the inner side of the fixing housing 32, and a gap is provided between the inner side of the receiving groove 33 and the horizontal plate 42. The electromagnet 34 and the permanent magnet block 52 are magnetically attracted. Through the above arrangement, this structural design provides stable support for the installation and fixing of the magnetic lock. The opening of the receiving groove 33 provides space for the installation and movement of subsequent components, while the fixed connection of the electromagnet 34 provides a reliable installation position for the energization of the magnetic lock, ensuring that the magnetic lock can stably perform its locking function.

[0033] As a further implementation of this scheme, there are two of each of the card plate 51 and the inclined plate 53. The top of the upper inclined plate 53 is attached to the inner side of the receiving groove 33, and the right end of the upper card plate 51 is attached to the inner side of the receiving groove 33. The outer sides of both inclined plates 53 are fixed with racks 54, and the inclined plates 53 are engaged with each other by the racks 54. Through the above settings, this design not only enhances the stability of the structure, but also further improves the locking effect of the door through the mechanical limiting effect. When the magnetic lock is energized, the cooperation between the card plate 51 and the inclined plate 53 can effectively prevent the door from being opened accidentally, greatly reducing the risk of accidental opening, thereby providing more reliable protection for the cultural relics inside the display case.

[0034] As a further implementation of this solution, the boss 43 is fixed with a cover plate by bolts, the groove is opened on the inner side of the horizontal plate 42, and the front and rear ends of the inclined plate 53 are both provided with bosses 43. The outer side of the shaft post 55 is fixedly connected to the inner side of the spring 45, and the shaft post 55 extends into the inside of the shaft hole 44. The inclined plate 53 is located inside the groove of the horizontal plate 42. Through the above settings, the stability of the structure is further enhanced, and the rotation of the inclined plate 53 is limited. At the same time, when the glass door 2 needs to be opened, the spring 45 can reset the locking plate 51 and the inclined plate 53, thereby improving the convenience of opening the glass door 2.

[0035] Workflow: When the glass door 2 and the display cabinet body 1 are magnetically locked, the glass door 2 is initially open, with both inclined plates 53 in contact with the baffle 46, and the electromagnet 34 is de-energized. Rotating the glass door 2 causes the frame assembly 4 and locking assembly 5 to rotate as a whole. The width of the receiving groove 33 is sufficient to allow the horizontal plate 42 and the locking plate 51 to enter the receiving groove 33 when the glass door 2 rotates. After the locking plate 51 and the horizontal plate 42 enter the receiving groove 33, there is sufficient clearance between the front and rear ends of the receiving groove 33 and the front and rear ends of the horizontal plate 42, which does not affect the locking between the display cabinet body 1 and the glass door 2. When the left side of the glass door 2 is in contact with the right side of the display cabinet body 1, the locking plate 51 and the horizontal plate 42 enter the receiving groove 33, the electromagnet 34 is energized, and under the magnetic attraction of the electromagnet 34 to the permanent magnet block 52, this... When the permanent magnet block 52 moves towards the electromagnet 34, the permanent magnet block 52 drives the locking plate 51 to rotate. The locking plate 51 drives the inclined plate 53 and the rack 54 to rotate around the shaft 55. The shaft 55 is rotatably connected to the inside of the boss 43. The shaft 55 drives the spring 45 to twist. The spring 45 plays the role of resetting the shaft 55. When the inclined plate 53 rotates, it drives the lower inclined plate 53 to rotate through the rack 54. This can improve the stability of locking. At this time, the upper part of the upper inclined plate 53 is in contact with the inner side of the receiving groove 33, and the right side of the locking plate 51 is in contact with the inner side of the receiving groove 33, thereby achieving the locking effect. This locking method not only increases the difficulty of accidentally opening the glass door 2 through magnetic force, but also further increases the difficulty of accidentally opening the glass door 2 through the limiting of the locking plate 51, thereby improving the safety of the protection of cultural relics inside the display cabinet body 1.

[0036] To open the glass door 2, the magnetic force of the electromagnet 34 is eliminated. Under the torsional action of the spring force of the clock spring 45, the shaft 55 rotates, which drives the inclined plate 53 to rotate. At this time, the two inclined plates 53 rotate simultaneously and are respectively attached to the upper or lower end of the baffle 46. The baffle 46 limits the angle of the torsion of the inclined plate 53, and then the glass door 2 is opened.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
