Technical Field
[0001] This invention relates to the field of display cabinet technology, and more specifically, to a display cabinet with multiple opening methods. Background Technology
[0002] Display cases are protective display stands provided for product display. Nowadays, in addition to placing beverages, display cases are often used for refrigeration to exhibit and store various foods and exhibits that require refrigeration. Most display cases are equipped with glass, which allows light to pass through while protecting the items. Most display cases generally have glass on one side, while the other three sides are usually made of opaque material. When using them, display operations can only be carried out from one side.
[0003] As people increasingly value display functionality, display cases have evolved from single-sided to multi-sided displays. However, limited by space size and placement, traditional display cases typically feature side-opening or sliding doors. Side-opening doors, with their outward-opening glass doors, often occupy significant space and can cause bumps and knocks in high-traffic areas. While sliding doors reduce the space required on the outside, the four sides cannot be folded in one direction, leaving the other three exposed, which also affects the display effect and inconveniences users. Therefore, we propose a display case with multiple opening methods. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0033] Please see Figures 1-9 The present invention provides a technical solution: a display cabinet with multiple opening methods, including a lower box 1 and an upper box 10 disposed above the lower box 1 and supported by multiple support rods 101. The interior of the upper box 10 is used to house components such as a thermostat and spotlights; the interior of the lower box 1 is used to house a compressor room, a refrigeration unit, etc.
[0034] Specifically, four adjacent glass doors 2 forming a rectangular shape are provided between the lower box 1 and the upper box 10. The top surface of the lower box 1 and the bottom surface of the upper box 10 are provided with an inner sliding groove 11 and an outer sliding groove 12 that are connected end to end. The outer sliding groove 12 is located outside the inner sliding groove 11. The glass doors 2 and the inner sliding groove 11 are rotatably connected by two sets of symmetrical hollow door hinges 20 on the left and right sides. The glass doors 2 and the outer sliding groove 12 are slidably connected.
[0035] In this embodiment, a pin hole 111 is provided on the groove wall at the corner of the inner slide groove 11. The glass door 2 has two symmetrical inner chambers 21. The hollow door shaft 20 is a hollow column and is fixedly installed on the glass door 2, communicating with the inner chambers 21. A connecting rod 25 is rotatably connected between the upper and lower walls of the inner chambers 21 via a rotating shaft, allowing the connecting rod 25 to perform lever movement along the rotating shaft. A pin rod 24 is slidably connected inside the hollow door shaft 20, and the pin rod 24 is inserted into the pin hole 111 for fixing. The inner chamber 21 has a fixed... A spring 242 is fixedly installed, with its two ends fixedly installed at the close ends of two pin rods 24. The glass door 2 is provided with two symmetrical handle grooves 22 on the left and right. One end of the connecting rod 25 is provided with a handle 26, which is located in the handle groove 22. The other end of the connecting rod 25 is fixedly installed with a wedge block 27 on the side of the plate. The wedge block 27 abuts against the two pin rods 24 to push the two pin rods 24 into the pin hole 111. The spring 242 is used to drive the pin rods 24 out of the pin hole 111 to complete the fixing and loosening operation.
[0036] Specifically, there are 8 pin holes 111 for inserting and fixing the two pins 24 on each glass door 2.
[0037] Furthermore, each of the two pin rods 24 has an inclined surface 241 on its end rods that are close to each other. The cross-section of the wedge block 27 is an isosceles triangle. After the side of the wedge block 27 abuts against the inclined surface 241, it is used to push the two pin rods 24 to move up and down respectively, and further drive the pin rods 24 to be inserted into the pin hole 111 to complete the fixing operation.
[0038] In addition, the inner slide 11 and the outer slide 12 are connected by four sets of inner through grooves 13 arranged in a matrix. Each set contains two inner through grooves 13. The four sets of inner through grooves 13 are located on the four side walls of the inner slide 11. The inner through grooves 13 are used for the hollow door shaft 20 to move from the inner slide 11 to the outer slide 12. The outer wall of the outer slide 12 is provided with multiple outer through grooves 14 that are connected to the outside. The outer through grooves 14 are used for the outward movement of the hollow door shaft 20 to disassemble and remove the glass door 2. The outer diameter of the hollow door shaft 20 is smaller than the inner width of the inner through groove 13 and the outer diameter of the hollow door shaft 20 is smaller than the inner width of the outer through groove 14, so that the hollow door shaft 20 can move normally from the outer through groove 14 and the inner through groove 13 for removal.
[0039] It is worth noting that the depth of the outer slide 12 is greater than the depth of the inner slide 11, and the width of the outer slide 12 is greater than the width of the inner slide 11. This is used to stably place the glass door 2 in the outer slide 12, and at the same time, it can also store multiple glass doors 2 on the same side of the outer slide 12, so that the other three sides are exposed, which is beneficial for display.
[0040] In this embodiment, two mutually symmetrical limiting grooves 23 are provided on the front side wall of the handle groove 22. The ends of the two limiting grooves 23 are connected through a guide groove 231. A protruding post 261 is fixedly installed on the rear side of the handle 26. The protruding post 261 is located in the handle groove 22 and is rotatably connected to the handle groove 22. The protruding post 261 is rotatably connected to the end plate of the connecting rod 25 through a rotating shaft. A protrusion 262 located in the limiting groove 23 and rotatably connected to the limiting groove 23 is fixedly installed on the protruding post 261. The protrusion 262 is used for limiting operation.
[0041] It is worth noting that the protrusion 262 located in the outer limiting groove 23 is used to drive the connecting rod 25 to move inward by lever movement, and the protrusion 262 located in the inner limiting groove 23 is used to drive the connecting rod 25 to move outward by lever movement and drive the pin rod 24 to extend outward.
[0042] When the display cabinet of the present invention with multiple opening methods is in use, in the normal operating state, the glass door 2 is located in the inner sliding groove 11. The protrusion 262 is aligned with the guide groove 231 and the handle 26 is pressed inward, so that the protrusion 262 slides into the limiting groove 23 located on the inner side. The handle 26 is rotated to drive the protrusion 262 to rotate into the limiting groove 23 and lock it on the front side wall of the limiting groove 23. As the protrusion 261 moves inward, the connecting rod 25 performs lever movement, which drives one side of the wedge block 27 to move outward. The wedge block 27 abuts against the inclined surface 241 and squeezes the inclined surface 241, which drives the two pin rods 24 to move up and down respectively. At this time, the pin rods 24 can be inserted into the pin hole 111 to complete the fixing operation, so that the glass door 2 can be placed normally and stably.
[0043] When opening the door to the side, ensure that the pin 24 on one side of each glass door 2 continues to be inserted into the pin hole 111, rotate the handle 26 on the other side until the protrusion 262 is aligned with the guide groove 231, and pull the handle 26 outward. At this time, the handle 26 is in the limiting groove 23 on the outside. As the protrusion 261 moves outward, the end of the connecting rod 25 near the protrusion 261 is also pulled outward appropriately. At this time, the connecting rod 25 continues to perform lever movement, driving one side of the wedge block 27 to move inward. The wedge block 27 no longer holds the pin 24 tightly. Under the force of the spring 242 returning to its original state, the pin 24 can be pulled out of the pin hole 111. At this time, the glass door 2 is only supported by the pin 24 on one side, and the glass door 2 can be opened normally outward along the pin 24 to complete the opening operation.
[0044] When sliding the door, first pull out the two handles 26 and the pins 24 on each glass door 2 from the pin holes 111. Then, move the glass door 2 from the inner slide groove 11 outward along the inner through groove 13 to the outer slide groove 12. Next, press one of the handles 26 and the pins 24 against the groove wall of the outer slide groove 12. At this time, the glass door 2 can be opened normally in a side-opening manner, ensuring that the glass door 2 moves along the outer slide groove 12 with one pair of pins 24 as the pivot. This allows the glass door 2 to be moved from one direction to another. After moving three of the glass doors 2 to the same direction as another glass door 2, the three directions can be directly exposed, which is beneficial for display.
[0045] Finally, pull out the handle 26 until the pin 24 is pulled out of the pin hole 111, and then align the hollow door shaft 20 with the outer through groove 14. This allows the glass door 2 to be disassembled and removed from the outer slide groove 12 for easy use.
