Detailed Implementation

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "top", "bottom", "inner", "outer", "left", "right", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Example 1:

[0035] refer to Figure 1 , Figure 2As shown, this utility model provides a glass door for a vertical display cabinet. The glass door is rotatably connected to the front opening side of the vertical display cabinet to close and open the cabinet. The glass door includes a door frame 10 and a glass assembly 30.

[0036] The door frame 10 includes four frame components 20 connected in sequence to form a U-shape; each frame component 20 includes an aluminum alloy profile 21 and an aluminum alloy frame 22. The aluminum alloy profiles 21 of all the frame components 20 are arranged to form a U-shaped frame structure, and the aluminum alloy frame 22 covers and is snapped onto the outer surface of the aluminum alloy profile 21, so that the outer surfaces of all the aluminum alloy frame 22 are completely covered by the aluminum alloy frame 22. A door handle 50 is also provided on one side of the door frame 10 for opening and closing the glass door.

[0037] To further explain, all aluminum alloy profiles 21 constitute the main structure of the door frame 10. Compared with plastic profiles in the prior art, aluminum alloy profiles 21 have higher strength and rigidity, better high-temperature resistance, and are more corrosion-resistant and oxidation-resistant, thus significantly increasing the service life of the door frame 10. Furthermore, compared with plastic frames in the prior art, the aluminum alloy frame 22 covering the aluminum alloy profiles 21 is less prone to damage due to its higher material strength, and the aluminum alloy frame is more aesthetically pleasing than the plastic frame, giving the vertical display cabinet a more modern and high-end feel. In addition, the frame usually has an inward snap-fit ​​structure for assembly with the profile; if the corner of the door frame 10 is a rounded design, the plastic frame is difficult to directly injection mold into a bent section that matches the rounded corner of the door frame 10 due to the inward snap-fit ​​structure. However, the aluminum alloy frame 22 can be bent and can be molded into a bent section that matches the rounded corner of the door frame 10. Therefore, the aluminum alloy frame 22 can better meet the styling requirements of the rounded corner of the door frame 10 and improve the aesthetics.

[0038] The glass assembly 30 includes a double-glazed glass 31 and an outer glass 32. The outer peripheral surface of the double-glazed glass 31 is fitted with the inner surface of the aluminum alloy profiles 21 of all the frame assemblies 20, that is, the double-glazed glass 31 is clamped within the U-shaped door frame 10. Each aluminum alloy profile 21 has a recessed receiving groove 201 on its mating surface with the double-glazed glass 31. The receiving groove 201 extends along the length of the aluminum alloy profile 21, specifically near the rear surface of the double-glazed glass 31. A heating wire 23 is provided in the receiving groove 201, thereby integrating the heating wire 23 into the aluminum alloy profile 21. The heating wire 23 is connected to the power supply of the vertical display cabinet. When the heating wire 23 is energized, it can heat the glass assembly 30, thereby reducing the temperature difference between the inside and outside of the glass assembly 30, preventing condensation on the glass door, avoiding affecting the refrigeration and display effect of the items inside the cabinet, and making it easier for consumers to see the items for sale inside the cabinet more clearly. The outer glass 32 is attached to the front surface of the insulating glass 31. The periphery of the outer glass 32 extends beyond the outer periphery of the insulating glass 31 and is bonded to the front surface of all aluminum alloy profiles 21. A process seam is left between the outer periphery of the outer glass 32 and the inner side of the front of all aluminum alloy frames 22 to facilitate assembly and release the stress caused by the difference in thermal expansion coefficients between the glass and the aluminum alloy.

[0039] In the above illustrative embodiment, by setting a heating wire 23 at the contact surface between the aluminum alloy profile 21 and the glass component 30, the glass component 30 can be heated to avoid condensation on the glass door. By adopting a structure in which the aluminum alloy profile 21 is wrapped with an aluminum alloy frame 22, the strength, rigidity and durability of the frame component 20 are improved, significantly increasing the service life of the door frame 10, and making the vertical display cabinet more beautiful and more high-end.

[0040] refer to Figure 2As shown, in some embodiments, the aluminum alloy profile 21 includes a front frame plate 211 and a rear frame plate 212 arranged opposite to each other. An inner frame plate 213 and an outer frame plate 214 are respectively connected between the front and rear ends of the front frame plate 211 and the rear frame plate 212. The rear ends of the inner frame plate 213 and the outer frame plate 214 both extend beyond the rear frame plate 212, so that the frame assembly 20 has a rear-opening snap-fit ​​groove 203. The inner frame plate 213 is fitted to the insulated glass 31, and the receiving groove 201 is recessed in the inner frame plate 213. The front end of the outer frame plate 214 extends beyond the front frame plate 211, and the front surface of the front frame plate 211 is bonded to the outer glass 32. The aluminum alloy frame 22 includes a main frame plate 221, a front latch 222 and a rear latch 223 connected to the front and rear sides of the main frame plate 221. The main frame plate 221 covers the outer frame plate 214, and the front latch 222 and the rear latch 223 are respectively engaged with the front and rear ends of the outer frame plate 214. The front surface of the front latch 222 is higher than the front surface of the outer glass 32. This illustrative embodiment refines the specific structure of the aluminum alloy profile 21 and the aluminum alloy frame 22, realizing the assembly connection of the aluminum alloy frame 22 to the aluminum alloy profile 21.

[0041] refer to Figure 2 As shown, in some embodiments, the door frame 10 further includes a plastic cover plate 40 covering the rear side of the frame assembly 20, that is, the plastic cover plate 40 is located on the side of the frame assembly 20 closer to the display cabinet body. The plastic cover plate 40 includes a main body 41 and a pressing part 42. The main body 41 has a latching part 43 protruding on the side facing the frame assembly 20, and the latching part 43 latches into the latching groove 203 of the frame assembly 20. It can be understood that there is a matching latching structure between the latching part 43 and the latching groove 203, including but not limited to latch hooks, latch claws, etc., which are not specifically limited here. The latching part 43 has a rear-opening receiving cavity 401, that is, the opening of the receiving cavity 401 faces the display cabinet body. On one side, a door seal is installed in the cavity 401, which acts as a buffer or seal when the glass door is opened and closed; one end of the pressing part 42 is connected to the side of the main body 41 near the inner frame plate 213, and the other end extends obliquely toward the insulating glass 31 and is pressed against the insulating glass 31; a reinforcing rib is also connected between the pressing part 42 and the main body 41, so that the main body 41, the pressing part 42 and the reinforcing rib are enclosed to form a hollow reinforcing structure, thereby improving the structural strength of the plastic cover plate 40.

[0042] refer to Figure 2 As shown, in some embodiments, a silkscreen area is provided on the front surface of the exterior glass 32, which covers the bonding area between the exterior glass 32 and all aluminum alloy profiles 21. Typically, the silkscreen area is arranged around the entire edge of the front surface of the exterior glass 32, which covers and beautifies the bonding area without affecting the display effect of the items inside the cabinet.

[0043] refer to Figure 2As shown, in some embodiments, the aluminum alloy profile 21 has an uneven texture 215 on its bonding surface with the outer glass 32, thereby increasing the contact area between the adhesive and the aluminum alloy profile 21, enhancing the bonding strength between the aluminum alloy profile 21 and the outer glass 32, and improving the sealing and waterproof performance between the two.

[0044] Example 2:

[0045] refer to Figure 3 As shown, based on Embodiment 1, the glass door is upgraded by adding a light strip 24. Specifically, the outer glass 32 is bonded to the front surface of all aluminum alloy profiles 21, but a relatively large gap is left between the outer periphery of the outer glass 32 and the inner side of the front of the aluminum alloy frame 22; each aluminum alloy profile 21 is also recessed on the front surface corresponding to the gap, the light groove 202 extends along the length of the aluminum alloy profile 21, and the light strip 24 is installed in the light groove 202. The outer surface of the light strip 24 is higher than the front surface of the aluminum alloy profile 21 and flush with the front surface of the outer glass 32. The two sides of the light strip 24 are respectively attached to the outer glass 32 and the aluminum alloy frame 22; the light strip 24 is connected to the power supply of the vertical display cabinet. When the light strip 24 is powered on, it emits light, so that the door frame 10 emits strip-shaped light all around, thereby making the glass door more fashionable and beautiful to attract consumers' attention.

[0046] refer to Figure 3 As shown, in some embodiments, at least one pair of retaining ribs protrude from the opposite side walls of the lamp groove 202, and the lamp strip 24 has grooves on both sides that match the retaining ribs, so that the lamp strip 24 can be snapped into the lamp groove 202, thereby realizing convenient assembly of the lamp strip 24 onto the aluminum alloy profile 21. Furthermore, the lamp strip 24 is a flexible LED light strip, which is soft in material, suitable for use in narrow spaces, has good insulation and waterproof properties, and a long service life; and because the lamp strip 24 is relatively soft, it can be hooked out with a hook-like object when disassembling, making it easy to inspect and replace the lamp strip 24.

[0047] Example 3:

[0048] Based on Example 2, the arrangement of the light strips 24 on the glass door is customized. Specifically, at least one aluminum alloy profile 21 has a light strip 24 on its front surface, which is referred to as a luminous profile segment; at least one aluminum alloy profile 21 does not have a light strip 24 on its front surface, which is referred to as a matte profile segment; a light groove 202 extending along its length is recessed on the front surface of the luminous profile segment, and a light strip 24 is installed in the light groove 202. The outer surface of the light strip 24 is higher than the front surface of the aluminum alloy profile 21 and flush with the front surface of the outer glass 32. The two sides of the light strip 24 are respectively attached to the outer glass 32 and the aluminum alloy frame 22; a process seam is left between the outer side of the outer glass 32 and the inner side of the front side of the aluminum alloy frame 22 located at the matte profile segment; thus, the position of the light strip 24 on the glass door can be personalized according to the required lighting effect, making the glass door fashionable, beautiful and more personalized, so as to attract consumers' attention.

[0049] In summary, the glass door of this utility model for a vertical display cabinet solves the various shortcomings of current vertical display cabinet glass doors on the market, avoids condensation on the glass door, improves the strength, rigidity and high-temperature resistance of the door frame, significantly increases the service life of the door frame, and makes the vertical display cabinet more stylish, beautiful and high-end.
