Description

Technical Field

[0001] This utility model relates to ice cream cabinets, and more particularly to a door opening structure and an ice cream cabinet. Background Technology

[0002] Ice cream display cases, as specialized refrigerated cabinets used for storing, displaying, and selling ice cream, directly impact user experience and operational efficiency through their design and functionality. Currently, the most common ice cream display cases on the market are divided into two main types: top-opening and side-opening. However, both types have certain limitations in hinge design and installation methods.

[0003] For freezers with top-opening doors: Hinges are typically installed along the upper rear edge of the cabinet and the rear edge of the door, allowing the door to open upwards. This hinge installation method makes the rear of the freezer no longer a flat surface, but rather protrude backwards, disrupting the overall aesthetic appearance of the freezer. Due to this hinge installation method, the overall size of the freezer increases, raising packaging and transportation costs. The freezer also occupies more space in the usage area, reducing space utilization. For freezers with side-opening doors, some have upper and lower hinges at the top and bottom of the cabinet opening, with hinge shafts on the hinges and hinge sleeves at the top and bottom of the door. The door rotates around the center line of the upper and lower hinge shafts when opening and closing. Others have hinges fixed to the left or right side of the door, with the other end of the hinge fixed to the cabinet. The door rotates around the central axis of the hinge when opening. Regardless of whether upper and lower hinges or hinges are used, the hinges or hinges are visible from the outside, affecting the aesthetic appearance of the freezer, and presenting the same problem as freezers with top-opening doors. Utility Model Content

[0004] The purpose of this utility model is to provide a door opening structure and an ice cream cabinet, in which the door hinge device is set in the cabinet space formed by the door and the cabinet body. When the door is closed, the door hinge device is not visible from the product exterior, which improves the appearance of the ice cream cabinet, while reducing the product's size, thereby reducing packaging and transportation costs and the space occupied.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A door opening structure includes a cabinet with an opening on its side or top. A door is installed at the opening, and when closed, the door forms a closed interior space with the cabinet. The interior space includes at least one hinge device and one gas strut or support rod. The hinge device includes at least two swing arms, one end of which is pivotally connected to the inner wall of the cabinet and the other end of which is pivotally connected to the door. One end of the gas strut is pivotally connected to the inner wall of the cabinet and the other end of which is pivotally connected to the inner side of the door. Alternatively, the upper end of the support rod is pivotally connected to the door, and the lower end is fixed against the interior of the cabinet.

[0007] Under the action of external force, the door can be flipped open by the linkage of the hinge device and the gas strut, and can remain stable in the open state; when the door is closed, the hinge device and the gas strut are completely stored in the cabinet space.

[0008] Preferably, the two swing arms of the hinge device have different lengths, with the shorter swing arm being the first swing arm located at the rear of the cabinet and the longer swing arm being the second swing arm located in front of the first swing arm, so that the door can be opened at an acute angle.

[0009] Preferably, the lengths of both the first and second swing arms are less than the stroke length of the gas strut.

[0010] Preferably, a gas strut or support rod is provided on each side of the opening of the cabinet, and / or a hinge device is provided symmetrically on both sides of the cabinet.

[0011] Preferably, the front ends of the first and second swing arms are pivotally connected to the inner wall of the cabinet, and the rear ends are pivotally connected to the door; the front end of the gas strut is pivotally connected to the inner side wall of the cabinet, and the rear end is pivotally connected to the door.

[0012] Preferably, the inner side of the door is provided with a fixing plate, which is perpendicular to the opening and extends in the front-to-back direction; the rear end of the first swing arm and / or the rear end of the second swing arm are connected to the fixing plate through a horizontally extending pivot shaft.

[0013] Preferably, a handle space is left between the front side of the door and the cabinet.

[0015] Preferably, the cabinet opening faces upward, the door is provided with an installation port, the ice cream bucket can be put into or taken out through the installation port, and the ice cream bucket is covered with a bucket lid.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] 1. The door opening structure of this invention, through a clever combination of a hinge device and a gas strut, ensures that after the door is opened, the hinge device and gas strut are completely retracted into the cabinet interior space and are not exposed to the outside. This design greatly improves the appearance of the freezer, avoiding the problem of exposed hinges or joints affecting the overall aesthetics in traditional designs, thereby enhancing the product's appearance quality and making it more in line with modern consumers' demands for aesthetics and refinement.

[0018] 2. Space-saving and reduced footprint: Because the hinge mechanism and gas strut are concealed within the cabinet space, this not only avoids the rear of the cabinet protruding but also effectively reduces the overall size of the freezer, thus saving space. This is especially beneficial in small commercial environments or home kitchens, effectively utilizing space and increasing the flexibility of the usage area.

[0019] 3. Because this invention reduces the external dimensions and protruding parts of the freezer, the freezer is more compact during packaging and occupies less space during transportation, thereby reducing packaging and transportation costs and resulting in significant economic benefits.

[0020] 4. This invention, through the linkage of the hinge device and the gas strut, enables the door to open smoothly and remain in a predetermined position. The cooperation between the hinge arm and the gas strut ensures that the door remains stable and smooth during opening, preventing the door from suddenly closing or failing to remain open due to external forces, thus ensuring safety and convenience during use.

[0021] 5. Due to the different lengths of the hinge arms, with the longer arms positioned at the front and the shorter arms at the rear, the door can open at an acute angle. Compared to traditional designs that occupy more space with large-angle opening, the acute-angle opening design of this invention saves space, making it particularly suitable for environments with limited space.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0031] Example 1

[0032] This embodiment is an ice cream display case, such as... Figures 1 to 4 This includes the door opening structure.

[0033] The door opening structure includes a cabinet body 1, a door body 2, a hinge device 3, and a gas strut 4. The cabinet body 1 has an opening at the top, and the door body 2 is mounted on top of this opening. The hinge device 3 and the gas strut 4 are fixed within the cabinet space 13 formed when the cabinet body 1 and door body 2 are closed. There are two sets of hinge devices 3 arranged symmetrically. Under external force, the door body 2 can be opened upwards by the linkage of the hinge device 3 and the gas strut 4, and can remain at a certain opening angle. When the door body 2 is closed, the hinge device 3 and the gas strut 4 are completely enclosed within the cabinet space 13, and the hinge device 3 is not visible from the outside of the cabinet body 1 and door body 2, thereby improving the product's aesthetics and reducing its overall size.

[0034] The structure adopts a combination of hinge device 3 and gas strut 4. The gas strut 4 is set on the openable side of the door 2, i.e. the front side, and the hinge device 3 is set on the other side, i.e. the rear side. One end of the gas strut 4 is pivotally connected to the inner side of the door, and the other end of the gas strut 4 is pivotally connected to the front or side of the inner liner of the cabinet 1, preferably the side of the inner liner.

[0035] The hinge device 3 includes at least two swing arms. One end of each swing arm is pivotally connected to the inner wall of the cabinet 1, and the other end is pivotally connected to the inner side of the door 2. In this embodiment, the hinge device 3 includes two swing arms of different lengths. The shorter swing arm is the first swing arm 31, located at the rear of the cabinet 1, and the longer swing arm is the second swing arm 32, located in front of the first swing arm 31, so that the door 2 can be opened at an acute angle.

[0036] In another embodiment, the inner side of the door 2 is integrally formed or fixedly connected to a fixing plate 21 by screws or other means. The fixing plate 21 is vertically downward and extends in the front-to-back direction. The rear end of the first swing arm 31 of the hinge device 3 is pivotally connected to the fixing plate 21 via a first pivot 211, and the rear end of the second swing arm 32 is pivotally connected to the fixing plate 21 via a second pivot 212, so that the first swing arm 31 and the second swing arm 32 can rotate around the corresponding pivot.

[0037] In another embodiment, the left and right inner walls of the cabinet 1 are respectively fixedly connected with the first positioning plates 11 arranged in front and behind. The front end of the first swing arm 31 of the hinge device 3 located on the same side is pivotally connected to the first positioning plate 11 through the third rotating shaft 111, and the front end of the second swing arm 32 is pivotally connected to the first positioning plate 11 through the fourth rotating shaft 112, so that the first swing arm 31 and the second swing arm 32 can rotate around the corresponding rotating shaft.

[0038] In another embodiment, the left and right inner walls or the front inner wall of the cabinet 1 are fixedly connected to a longitudinally extending second positioning plate 12. The front end of the gas strut 4 is pivotally connected to the second positioning plate 12 via a first pin 121, and the rear end of the gas strut 4 is pivotally connected to the aforementioned fixed plate 21 via a second pin 113. Alternatively, the rear end of the gas strut 4 can be pivotally connected to another fixed plate 21. Of course, it can also be directly pivotally connected to the inner side of the door 2, so that the gas strut 4 can rotate around the corresponding pin.

[0039] In this embodiment, when the door 2 is opened, the gas strut 4 opens and pushes the door 2 upward and forward. At this time, the gas strut 4 rotates clockwise around the first pin 121 of the second positioning plate 12, causing the first swing arm 31 to rotate clockwise around the third pivot 111 of the first positioning plate 11, and the second swing arm 32 to rotate clockwise around the fourth pivot 112 of the first positioning plate 11. The length of the second swing arm 32 is greater than the stroke length of the first swing arm 31 and less than the stroke length of the gas strut 4, so that the door 2 can open at a certain acute angle. When the maximum stroke length of the gas strut 4 is reached, the door 2 can stop at this point. When the door 2 is subjected to a downward external force, the gas strut 4 retracts, and the front end of the gas strut 4 rotates counterclockwise around the first pin 121 of the second positioning plate 12, which drives the first swing arm 31 to rotate counterclockwise around the third pivot 111 of the first positioning plate 11, and the second swing arm 32 to rotate counterclockwise around the fourth pivot 112 of the first positioning plate 11, pushing the door 2 to move downward and backward until the door 2 and the cabinet 1 are completely closed.

[0040] To facilitate the opening of the door 2, a gap is reserved between the front side of the cabinet 1 and the door 2 to form a handle space 22. The gap is large enough to easily insert a finger to open and close the door, which is equivalent to having a handle space 22 pre-set at the front of the door 2. The inner side of the door 2 is provided with a door seal 23 around the perimeter, which serves to seal the door when it is closed.

[0041] To ensure the overall aesthetic appearance of the product, when door 2 is closed, the sides of door 2 are flush with the sides of cabinet 1.

[0042] Door 2 is provided with an installation opening 24, in which an ice cream bucket 5 is fixedly placed. The ice cream bucket 5 is covered with a bucket lid 51. The ice cream can be taken out of the ice cream bucket 5 by removing the bucket lid 51. When the inside of cabinet 1 needs to be cleaned, the ice cream bucket 5 is first taken out from the installation opening 24, and then the door 2 is opened. After the inside of cabinet 1 is cleaned, the door 2 is closed, and then the ice cream bucket 5 is put back into the installation opening 24.

[0043] Example 2

[0044] A kitchen freezer includes a door opening structure. For convenient storage, the cabinet 1 has an opening on the side, and the door 2 is located on the side. The hinge device 3 and the gas strut 4 are symmetrically arranged vertically within the cabinet space. The door 2 can be opened to the left or right and stay in a certain position. The structure and fixing method of the hinge device 3 and the gas strut 4 are similar to those in Embodiment 1. A handle space 22 is provided between the front side of the door 2 and the side of the cabinet 1. When the door 2 is closed, the front of the door 2 is flush with the front of the cabinet 1.

[0045] Example 3

[0046] like Figure 5 The difference from Embodiment 1 is that the rear end of the first swing arm 31 of the hinge device 3 is pivotally connected to a fixed plate 21, the rear end of the second swing arm 32 is pivotally connected to another fixed plate 21, the front end of the first swing arm 31 of the hinge device 3 is pivotally connected to a first positioning plate 11, and the front end of the second swing arm 32 is pivotally connected to another first positioning plate 11. The rest is the same as in Embodiment 1.

[0047] Example 4

[0048] like Figure 6 The difference from Embodiment 1 is that a support rod 6 is used instead of a gas strut 4. The bottom of the support rod 6 is provided with a positioning pin 61. The first positioning plate 11 is provided with a horizontal extension, and a positioning pin fixing hole is provided on the horizontal extension. The upper end of the support rod 6 is pivotally connected to the fixing plate 21 through a rotating shaft. When the door is opened to a certain angle, the positioning pin 61 is inserted into the positioning pin fixing hole, so that the door 2 cannot fall. When the door 2 is to be closed, the positioning pin 61 is pulled out from the positioning pin fixing hole, so that the door 2 falls and closes.
