Description

[Technical field]

[0001] The present application belongs to the technical field of refrigerated display cabinets, and in particular relates to a glass door cabinet with hovering and automatic door return functions. [Background technology]

[0002] At present, multi-door refrigerated vertical display cabinets are widely used in supermarkets, convenience stores and other scenarios. Multi-door cabinets refer to glass door cabinets with more than or equal to 2 glass doors. In order to facilitate the placement and removal of goods in the cabinet, more and more customers require that the glass doors of the glass door cabinets have a hovering function. Existing multi-door refrigerated cabinets generally use an external torsion spring return door structure. This structure has a special hovering device to ensure that the glass door stops when it is opened to 90°. However, the torsion spring automatic return door force is too large, and the noise generated when closing the door is relatively large. The vibration generated can easily shake the items in the cabinet off. At the same time, the hovering device is exposed and complicated to install, and the durability and overall aesthetics of the refrigerator are poor. [Utility Model Content]

[0003] In order to solve the problem that the suspension device in the prior art is external, which reduces the durability and aesthetics of the refrigerator, the present application provides a glass door cabinet with suspension and automatic door return functions that can eliminate the external suspension device, so that the glass door looks more natural when it is suspended at an angle greater than or equal to 90°, and the overall appearance of the multi-door cabinet is more concise and beautiful.

[0007] As described above, in a glass door cabinet with hovering and automatic door return functions, when the door panel assembly is opened relative to the door cabinet body by forward rotation to an angle of less than 90°, the forward rotation of the mounting member drives the second inclined surface on the linkage member to rise along the first inclined surface on the door shaft, so that the linkage member moves along the sliding cavity toward the positioning member, and at the same time, the elastic compression spring is compressed, and the linkage member moves away from the positioning member under the action of the elastic force of the elastic compression spring, and the second inclined surface on the linkage member reverses and descends along the first inclined surface on the door shaft, driving the mounting member to reverse, so that the door panel assembly is reversed and closed relative to the door cabinet body.

[0008] In a glass door cabinet with hovering and automatic door return functions as described above, when the door panel assembly rotates forward relative to the door cabinet body to open to an angle greater than or equal to 90°, the mounting member rotates forward to drive the second inclined surface on the linkage member to rise forward along the first inclined surface on the door shaft until the first plane abuts against the first vertex, so that the door panel assembly remains stationary relative to the door cabinet body to keep the glass door cabinet open.

[0009] In the glass door cabinet with hovering and automatic door return functions as described above, the radian of the horizontal projection surface of the first inclined surface is greater than or equal to π / 2rad.

[0010] In the glass door cabinet with hovering and automatic door return functions as described above, a limit block is provided on the linkage member, and a limit groove is provided in the sliding cavity for the limit block to be slidably connected so that the linkage member and the mounting member rotate synchronously.

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] See also Figures 1 to 4 A glass door cabinet with hovering and automatic door return functions, comprising a door return assembly 1, a door cabinet body 2, and a door panel assembly 3 movably connected to one side of the door cabinet body 2 through the door return assembly 1, wherein the door panel assembly 3 is provided with an installation cavity 4 for the door return assembly 1 to be embedded in. When the angle between the door panel assembly 3 and the door cabinet body 2 is less than 90°, the door return assembly 1 drives the door panel assembly 3 to rotate toward the door cabinet body 2 to close the glass door cabinet. When the angle between the door panel assembly 3 and the door cabinet body 2 is greater than or equal to 90°, the door return assembly 1 keeps the door panel assembly 3 stationary relative to the door cabinet body 2 to keep the glass door cabinet open.

[0024] The present application discloses a glass door cabinet with hovering and automatic door return functions, wherein a door return component is arranged inside the door panel component, which drives the door panel component and the door cabinet body to automatically return when the angle between the component and the door panel component is less than 90 degrees, and to automatically hover when the angle between the component and the door panel component is greater than or equal to 90 degrees. This protects the door return component from being bumped for a long time, thereby effectively extending the service life. Furthermore, the built-in door return component can improve the simplicity and aesthetics of the overall appearance of the multi-door cabinet.

[0025] Further, as a preferred embodiment of the present scheme but not a limitation, the return door assembly 1 includes a mounting member 11 connected to the door panel assembly 3, a sliding cavity 12 provided in the mounting member 11, a door shaft 13 with one end embedded in the sliding cavity 12 and the other end protruding from the door panel assembly 3 and the door cabinet body 2, a linkage member 14 slidably connected to the sliding cavity 12 and abutting against the door shaft 13, a positioning member 15 provided in the sliding cavity 12, and an elastic compression spring 16 provided between the linkage member 14 and the positioning member 15; the door shaft 13 is provided with a first inclined surface 131 arranged upward along the rotation and opening direction of the door panel assembly 3 relative to the door cabinet body 2 and a first vertex 132 located at the end of the first inclined surface 131; the linkage member 14 is provided with a first plane 141 and a second inclined surface 142 abutting against the first inclined surface 131; the linkage member 14 and the positioning member 15 rotate synchronously with the mounting member 11.

[0026] In this embodiment, through the structural design of the door shaft and the linkage, when the door panel assembly rotates during the opening or closing process, the linkage can be closely matched with the door shaft to ensure the stability and smoothness of the door panel assembly. In addition, compared with the torsion spring return door method used in the prior art, the setting of the positioning member and the elastic compression spring increases the slope and friction of the first and second inclined surfaces, which can ensure that the door panel assembly can return slowly when closed, thereby effectively preventing noise and vibration. Overall, this structural design enhances the service life of the door cabinet, improves its stability and safety, and also brings a better user experience to users.

[0027] Further, as a preferred implementation mode of the present scheme but not a limitation, when the door panel assembly 3 is opened relative to the door cabinet body 2 by forward rotation to an angle less than 90°, the forward rotation of the mounting member 11 drives the second inclined surface 142 on the linkage member 14 to rise forward along the first inclined surface 131 on the door shaft 13, so that the linkage member 14 moves along the sliding cavity 12 toward the positioning member 15, and at the same time, the elastic compression spring 16 is compressed, and the linkage member 14 moves away from the positioning member 15 under the action of the elastic force of the elastic compression spring 16, and the second inclined surface 142 on the linkage member 14 reverses and descends along the first inclined surface 131 on the door shaft 13, driving the mounting member 11 to reverse, so that the door panel assembly 3 is reversed and closed relative to the door cabinet body 2.

[0028] Furthermore, as a preferred implementation mode of the present invention but not a limitation thereof, when the door panel assembly 3 is opened by forward rotation relative to the door cabinet body 2 to an angle greater than or equal to 90°, the forward rotation of the mounting member 11 drives the second inclined surface 142 on the linkage member 14 to rise forward along the first inclined surface 131 on the door shaft 13 until the first plane 141 abuts against the first vertex 132, so that the door panel assembly 3 remains stationary relative to the door cabinet body 2 to keep the glass door cabinet open.

[0029] Furthermore, as a preferred implementation manner of the present solution but not a limitation, the radian of the horizontal projection surface of the first inclined surface 131 is greater than or equal to π / 2rad.

[0030] In this embodiment, the door panel assembly can automatically hover when it is opened to an angle greater than or equal to 90° in the forward rotation relative to the door cabinet body, and can automatically return to close when it is opened to an angle less than 90° in the forward rotation relative to the door cabinet body, thereby providing users with a smoother and more convenient opening and closing experience.

[0031] Furthermore, as a preferred implementation of the present solution but not a limitation, a limit block 143 is provided on the linkage member 14 , and a limit groove 121 is provided in the sliding cavity 12 for the limit block 143 to be slidably connected so that the linkage member 14 and the mounting member 11 rotate synchronously.

[0032] In this embodiment, the setting of the limit block and the limit groove can only limit the rotation of the linkage part relative to the sheet metal part, but does not limit the sliding of the linkage part along the sliding groove relative to the sheet metal part, ensuring that the linkage part can normally drive the sheet metal part to rotate, and then drive the door panel assembly to automatically return to the door.

[0033] Furthermore, as a preferred implementation mode of the present invention but not a limitation, it includes four limit blocks 143 arranged along the circumference of the linkage member 14 , and four limit grooves 121 arranged along the circumference of the sliding cavity 12 and corresponding to the limit blocks 143 one by one.

[0034] In this embodiment, the combination of the four limit blocks and the limit grooves not only enhances the stability and durability of the door cabinet, but also provides users with a smoother, safer and more reliable use experience.

[0035] Furthermore, as a preferred embodiment of the present invention but not a limitation, the door panel assembly 3 includes a glass door panel 31 and a left door frame strip 32, a right door frame strip 33, an upper door frame strip 34 and a lower door frame strip 35 arranged around the glass door panel 31, and the mounting member 11 is L-shaped.

[0036] In this embodiment, the four door frame strips surrounding the glass door panel provide sufficient support and protection for the door panel, ensuring the safety and structural integrity of the door panel. In addition, the L-shaped design of the mounting piece not only simplifies the installation process and improves the installation efficiency, but also enhances the overall stability and firmness of the door cabinet.

[0037] Furthermore, as a preferred implementation mode of the present invention but not limiting, it includes two return door assemblies 1 located on the same side of the door panel assembly 3 and symmetrically arranged in the vertical direction.

[0038] In this embodiment, when the door panel assembly is a left-opening door, the return door assembly is arranged on the left side of the door panel assembly and is hinged to the door cabinet body; when the door panel assembly is a right-opening door, the return door assembly is arranged on the right side of the door panel assembly and is hinged to the door cabinet body. The symmetrical layout enhances the overall balance and stability of the door cabinet and ensures the smoothness and balance during operation. Secondly, this symmetrical configuration improves the operability and convenience of the door cabinet.

[0039] Furthermore, as a preferred implementation manner of the present solution but not a limitation, a limit stopper 5 is also included at the bottom of the door panel assembly 3 .

[0040] In this embodiment, the setting of the limit stopper can prevent the glass door from opening at too large an angle and damaging the door panel assembly and the return door assembly, thereby increasing the service life.

[0041] The working principle of this embodiment is as follows:

[0042] The present application discloses a glass door cabinet with hovering and automatic door return functions, wherein a door return component is arranged inside the door panel component, which drives the door panel component and the door cabinet body to automatically return when the angle between the component and the door panel component is less than 90 degrees, and to automatically hover when the angle between the component and the door panel component is greater than or equal to 90 degrees. This protects the door return component from being bumped for a long time, thereby effectively extending the service life. Furthermore, the built-in door return component can improve the simplicity and aesthetics of the overall appearance of the multi-door cabinet.

[0043] The above are implementation methods provided in combination with specific contents, and it is not intended that the specific implementation of this application is limited to these descriptions. Any method structure similar to the present application, or some technical deductions or replacements made based on the concept of the present application, shall be deemed to be within the protection scope of this application.
