Abstract
Description
Technical Field
[0001] This invention relates to the field of display cabinet technology, specifically to a display cabinet with an adjustable shelf height and its installation method. Background Technology
[0002] Display cases are widely used in various venues such as product displays, warehousing and logistics, retail stores, museums, and libraries. Traditional display cases typically have shelves or partitions with fixed shelf heights, and once installed, the height between each shelf cannot be easily changed. However, in practical applications, the size and height of the items to be displayed or stored often vary. When taller items need to be displayed, fixed-height display cases may not be able to accommodate them due to insufficient shelf height; while when storing shorter items, the upper space is wasted, reducing the space utilization and flexibility of the display case.
[0003] To overcome the aforementioned problems, some shipping containers with adjustable shelf heights have emerged on the market. Common adjustment methods include: creating equally spaced adjustment holes on the uprights on both sides of the container, allowing adjustment by inserting pins or clips at both ends of the partition into holes of different heights; or using bolts, screws, or other fasteners to directly lock the partitions to specific positions on the uprights. While these methods achieve some adjustment functionality, they still have significant shortcomings. For example, using adjustment holes limits the height adjustment to preset hole positions, preventing stepless adjustment and limiting flexibility. Furthermore, frequent insertion and removal of clips or pins can easily cause wear on the holes, affecting the connection's stability. Summary of the Invention
[0004] The problem this invention aims to solve is to provide a display cabinet with an adjustable shelf height and its installation method. By setting up a frame consisting of a base plate and columns, and placement panels with height adjustment components, the height of each placement panel can be infinitely and flexibly adjusted according to the size of the displayed goods and display requirements. This avoids the shortcomings of traditional display cabinets with fixed shelf heights and low space utilization, and is especially suitable for displaying goods with large differences in size and height, effectively improving the adaptability and utilization efficiency of the internal space of the display cabinet.

[0025] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.
[0026] Example 1
[0027] like Figure 1-9 As shown, this embodiment discloses a display cabinet with an adjustable shelf height, specifically including a cabinet body 1 and a shelf disposed inside the cabinet body 1; The placement rack includes a frame, several placement plates 6, and a height adjustment component. The frame includes a base plate 3 and several uprights 4. The uprights 4 are vertically installed at the edge of the base plate 3. The placement plates 6 are provided with mounting holes that cooperate with the uprights 4. The height adjustment component is provided on the placement plate 6. The height adjustment component can be locked or contact-locked with the uprights 4 as needed to adjust the position of the placement plate 6 on the uprights 4.
[0028] In this embodiment, specifically, the height adjustment component includes a locking ring 7 and a drive ring 5. The locking ring 7 is installed on the placement plate 6 at a position corresponding to the mounting hole. The locking ring 7 is movably engaged with the column 4. The drive ring 5 is fitted onto the locking ring 7. The outer circumferential surface of the locking ring is provided with an external thread, and the inner ring of the drive ring is provided with an internal thread that engages with the external thread.
[0029] The locking ring 7 has a tapered surface 9 on its outer circumference, and the driving ring 5 has a tapered surface 11 on its inner ring that mates with the tapered surface 9. Furthermore, the locking ring 7 is made of a flexible, deformable material. Additionally, the locking ring 7 has several axial deformation grooves 10.
[0030] In the above solution, the height adjustment component combines a threaded drive ring with a flexible locking ring. During adjustment, simply rotating the drive ring causes its inner conical surface to press against the outer conical surface of the locking ring, resulting in radial contraction of the locking ring and a firm grip on the column, enabling quick locking and unlocking of the placement plate. This structure has a simple and reliable mechanical principle, provides a large locking force, ensures the stability of the placement plate when carrying goods, and requires no additional tools; a single person can easily complete the adjustment. Simultaneously, the locking ring is made of a flexible, deformable material and features axial deformation grooves, allowing it to undergo uniform and smooth elastic deformation under the pressure of the drive ring. This ensures a full fit with the column and sufficient locking force while reducing stress concentration, improving the fatigue life and reliability of the locking ring for repeated use.
[0031] In existing display cases, cabinet doors and corresponding locking devices are often installed to protect the goods or items inside. Conventional cabinet door locks mostly use mechanical lock cylinders combined with keys or combination knobs to achieve opening and closing control. Such locks are simple in structure and low in cost, but they have limitations in terms of ease of use and intelligence. For example, in situations requiring frequent opening and closing or centralized management (such as retail stores, museums, warehouses, etc.), traditional mechanical locks require manual operation one by one, which is inefficient and difficult to achieve remote control or linkage with other security systems. Therefore, in this embodiment, the cabinet body 1 is provided with a push-pull cabinet door 2. Furthermore, the cabinet door 2 is provided with a switch lock that can control the opening and closing of the cabinet door 2. Specifically, the switch lock includes a lock body 12 and a drive component and a lock head 21 disposed inside the lock body 12.
[0032] More specifically, the driving component includes an electromagnet 13 and a connector. The lock body 12 has an internal mounting cavity 14. The connector is movably mounted in the mounting cavity 14. The electromagnet 13 is fixedly mounted at the bottom of the mounting cavity 14. When the electromagnet 13 is energized, it can engage with the connector. One end of the connector is connected to the lock head 21. The lock body 12 has an internal movable hole for the lock head 21 to move. One end of the lock head 21 can pass through the movable hole and engage with a lock hole located at a corresponding position on the container body 1.
[0033] Those skilled in the art will recognize that existing electromagnetic locks generally lack sufficient sealing. A gap typically exists between the bolt and the guide hole, making it difficult to effectively prevent external dust and moisture from entering the lock body, potentially damaging internal electromagnets, circuits, and other precision components. Although some locks use simple rubber rings for sealing, these rings are prone to wear and deformation during the reciprocating motion of the bolt, resulting in a decrease in sealing effectiveness over time and potentially increasing resistance to movement. Therefore, in this embodiment, the switch lock further includes a sealing assembly for sealing the mating point between the lock head 21 and the movable hole. The sealing assembly includes a sealing ring 24, a mating ring 27, and a return spring 23. The connector includes a movable post 16, a suction plate 15, a connecting rod 18, and a mating plate 19. The movable post 16 is provided with a mating cavity 17 that mates with the mating plate 19. The mating cavity 17 is provided with a through hole for the connecting rod 18 to move. One end of the connecting rod 18 is fixedly connected to the suction plate 15, and the other end is fixedly connected to the mating plate 19. The suction plate 15 is made of magnetic material, and the movable post 16 is made of non-magnetic material (the lock head is also made of non-magnetic material). The movable hole has a hole wall with... The lock body 12 has a sealing groove, and the sealing ring 24 is installed in the sealing groove. The sealing ring 24 is provided with an annular deformation groove 25. The groove wall of the annular deformation groove 25 is provided with a conical surface 3 8. The outer circumference of the mating ring 27 is provided with a conical surface 4 26 that mates with the conical surface 3 8. One end of the mating ring 27 is connected to the mating plate 19 through several linkage rods 20. The bottom of the mating cavity 17 is provided with several mating holes 1 for the linkage rods 20 to pass through. The lock body 12 is also provided with a receiving groove 22 for installing a return spring 23. One end of the return spring 23 is fixedly connected to the bottom of the receiving groove 22, and the other end is fixedly connected to the mating plate 19. The bottom of the mating cavity 17 is provided with several mating holes 22 for the return spring 23 to pass through.
[0034] In the above scheme, when the power is off, the electromagnet is not energized, and the return spring is in its natural state, causing the mating plate and its connected linkage rod and mating ring to move towards the lock head. At this time, the outer conical surface of the mating ring presses against the conical surface of the sealing ring, causing the sealing ring to undergo radial elastic deformation along its annular deformation groove. The inner ring tightly hugs the surface of the lock head or the wall of the movable hole, forming a reliable sealing interface that effectively prevents external dust and moisture from entering the lock body. At the same time, the lock head remains extended under the action of the return spring, engaging with the lock hole on the container body to lock the cabinet door. When unlocking is required, the control power is turned on, the electromagnet is energized and generates magnetic force, attracting the magnetically attached plate. The attached plate, through the connecting rod, drives the mating plate to move towards the electromagnet against the force of the return spring. The movement of the mating plate, through the linkage rod, synchronously drives the mating ring to move away from the sealing ring. As the mating ring releases the pressure on the conical surface of the sealing ring, the sealing ring returns to its original shape due to its own elasticity, the clamping force between its inner wall and the lock head is released or significantly reduced, and the friction between the two is greatly reduced. Until the mating plate contacts the upper surface of the mounting cavity, the mating plate drives the movable column and the lock head to retract into the lock body. The lock head disengages from the lock hole of the container body, and the cabinet door can be opened. During this process, the release of the sealing ring precedes the obvious movement of the lock head, ensuring that the lock head is in a low-friction environment when it begins to move axially, resulting in smooth movement and minimal wear on the sealing ring. After the unlocking operation is completed, the control power is disconnected, and the electromagnet's magnetic force disappears. Under the action of the return spring, the mating plate drives the linkage rod and the mating ring to move in the opposite direction, and the lock head extends accordingly. When the mating ring presses against the conical surface of the sealing ring again, the sealing ring deforms again and fits tightly against the lock head, restoring the sealing state. Subsequently, the lock head fully extends and enters the lock hole, completing the locking. Because this lock is in a power-off locked state for a long period of time during non-operation periods, the sealing ring is in a compressed sealing posture most of the time, effectively preventing the intrusion of external contaminants during the lock head's static period. The sealing ring is only briefly released during the brief moment of opening and closing the lock to reduce friction. This design balances low wear during dynamic processes with high sealing performance during static periods, significantly improving the lock's environmental tolerance and service life.
