[0003] A hinge is a mechanical device used to connect two fixed parts, allowing relative rotation between them. A hinge typically consists of a movable hinge cup and a fixed base. The movable hinge cup is used to secure the hinge to the cabinet door, while the fixed base is used to secure it to the door frame. Existing hinge bases are usually installed using screws, a time-consuming process that requires tools such as screwdrivers to tighten the screws, making it rather cumbersome. Utility Model Content

[0004] In order to overcome the defects of the prior art, the present invention provides a quick-installation structure for a hinge base and a cabinet door assembly, which not only enables the quick installation of the hinge base, but also eliminates the need for fastening tools, making installation convenient.

[0005] The technical solution adopted by this utility model to solve its problem is: A quick-release structure for a hinge base, comprising: The base body has expanding rubber particles at its bottom; the expanding rubber particles have an expanding portion. An expansion pin is inserted through the base body and at least partially into the expansion granules; the expansion pin has a conical portion that abuts against the expansion portion. A cover plate is hinged to the expansion pin; the cover plate abuts against the base body to form a swing support point; when the cover plate is swung, the expansion pin can be moved synchronously. The cover plate has a first position and a second position when it swings. When the cover plate is driven to swing to the first position, the cone portion drives the expansion portion to expand outward. When the cover plate is driven to swing to the second position, the cone portion releases the expansion of the expansion portion, and the expansion portion returns to its original position.

[0006] As an optional implementation, the expanding granules include at least two segmented granules arranged circumferentially spaced apart, the segmented granules forming the expanding portion.

[0007] As an optional implementation, the cone portion includes a first truncated cone circumferentially disposed on the outer side wall of the expansion nail, and a first conical surface adapted to the shape of the first truncated cone is formed on the inner side wall of the segmented pellet, the first conical surface abutting and engaging with the first truncated cone.

[0008] As an optional implementation, the cone portion further includes a second truncated cone arranged around the outer wall of the expansion nail, with the first truncated cone and the second truncated cone arranged vertically at intervals; the inner wall of the segmented pellet is provided with a second conical surface adapted to the shape of the second truncated cone, and the second conical surface abuts and engages with the second truncated cone.

[0009] As an optional implementation, the base body has a through hole communicating with the expanding rubber particles, and one end of the expanding nail passes through the through hole, wherein: The expansion nail has a hinge hole at the portion passing through the through hole, and the cover plate is hinged to the expansion nail by passing through the hinge hole via a hinge shaft.

[0010] As an optional implementation, the cover plate includes a main body portion, both sides of which are bent to form side plate portions, and the two ends of the hinge shaft are respectively connected to the two side plate portions.

[0011] As an optional implementation, a horizontally arranged first abutment surface is formed at the bottom of the side plate portion, and a convex second abutment surface is formed on one side of the bottom of the side plate portion, wherein the first abutment surface and the second abutment surface are connected and transitioned. The cover plate abuts against the base body through the first abutment surface and the second abutment surface to form a swing support point.

[0012] As an optional implementation, two of each of the expanding rubber granules, the expanding nails, and the cover plates are provided and are respectively located on the left and right sides of the base body; the two cover plates are connected by a connecting plate to form a linkage.

[0013] As an optional implementation, the expanding granules are made of plastic, and the expanding nails are made of plastic or metal.

[0014] In addition, this utility model also provides a cabinet door assembly, including a door frame and the aforementioned quick-installation structure, wherein: The door frame is provided with mounting holes, and the expanding rubber particles extend into the mounting holes; When the cover plate is driven to swing to the first position, the cone portion drives the expansion portion to expand outward, and the expansion granules are interference-fitted with the mounting holes to fix the base body on the door frame.

[0015] In summary, the quick-installation structure for a hinge base and a cabinet door assembly provided by this utility model allows for the installation of the base by first inserting an expanding rubber granule into the mounting hole of the door frame. Then, the cover plate is driven to swing from the second position to the first position, causing the conical portion to expand outwards. The expanding rubber granule fits into the mounting hole with an interference fit, thereby fixing the base body to the door frame. Therefore, this structure enables rapid installation of the hinge base, saving installation time and improving installation efficiency. Furthermore, it eliminates the need for fastening tools, making installation convenient. Attached Figure Description

[0018] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" 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 module 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.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] See Figure 1-7 This utility model provides a quick-release structure for a hinge base, including a cross-shaped base body 1. The bottom of the base body 1 is provided with an expanding rubber granule 2, which has an expanding portion. It also includes an expanding pin 3 and a cover plate 41. The expanding pin 3 passes through the base body 1 and at least partially extends into the expanding rubber granule 2. The expanding pin 3 has a conical portion 31, which abuts against the expanding portion. The cover plate 41 is hinged to the expanding pin 3, and partially abuts against the base body 1 to form a swing support point. When the cover plate 41 is swung, the expanding pin 3 can be moved up and down simultaneously. The cover plate 41 has a first position and a second position during swinging. When the cover plate 41 is driven to swing to the first position (e.g., ...), ... Figure 6 As shown), the conical part 31 can drive the expansion part to expand; when the drive cover plate 41 swings to the second position (as shown), the cone part 31 can drive the expansion part to expand; Figure 1 As shown), the cone portion 31 releases the expansion of the expansion portion, and the expansion portion returns to its original position.

[0022] Therefore, when installing the base, the expanding rubber granules 2 are first inserted into the mounting holes of the door frame. Then, the cover plate 41 is driven to swing from the second position to the first position. The conical part 31 drives the expansion part to expand outward. The expanding rubber granules 2 are press-fitted into the mounting holes, thereby fixing the base body 1 to the door frame. Thus, the above structure allows for quick installation of the hinge base, saving installation time and improving installation efficiency. Furthermore, it eliminates the need for fastening tools, making installation convenient.

[0023] See Figure 2-4Specifically, the expanding granule 2 includes two circumferentially spaced sub-granules 21, which form an expanding portion. A gap is formed between the two sub-granules 21 to provide space for their outward deformation. The conical portion 31 of the expanding nail 3 includes a first truncated cone 311 and a second truncated cone 312 arranged around the outer wall of the expanding nail 3, with the first truncated cone 311 and the second truncated cone 312 arranged vertically at intervals. The inner sidewall of the sub-granule 21 has a first conical surface 22 that matches the shape of the first truncated cone 311 and a second conical surface 23 that matches the shape of the second truncated cone 312. The first conical surface 22 abuts against the first truncated cone 311, and the second conical surface 23 abuts against the second truncated cone 312.

[0024] Therefore, when the drive cover plate 41 swings to move the expansion nail 3 up and down, the expansion nail 3 can abut against the first cone surface 22 and the second cone surface 23 through the first cone 311 and the second cone 312 respectively to expand the segmented particles 21 outwards. Figure 7 As shown.

[0025] Of course, in other embodiments, the expanding granule 2 may also include three or more segmented granules 21, and the number of segmented granules 21 is not limited here.

[0026] See Figure 2 as well as Figure 5 The base body 1 has a through hole 11 that connects to the expansion granules 2. The upper end of the expansion nail 3 passes through the through hole 11. The part of the expansion nail 3 that passes through the through hole 11 has a hinge hole 32. The cover plate 41 is hinged to the expansion nail 3 by passing through the hinge hole 32 through a hinge shaft 5.

[0027] The cover plate 41 includes a main body 411, both sides of which are bent to form side plates 412. Each side plate 412 has a fixing hole 4121, and both ends of the hinge shaft 5 are connected to the fixing holes 4121 of the side plates 412. A horizontally arranged first abutment surface 4122 is formed at the bottom of each side plate 412, and a protruding second abutment surface 4123 is formed on one side of the bottom of each side plate 412. The first abutment surface 4122 and the second abutment surface 4123 are connected and transitioned. The cover plate 41 abuts against the base body 1 through the first abutment surface 4122 and the second abutment surface 4123 to form a swing support point.

[0028] Therefore, when the drive cover 41 swings to the second position (such as...) Figure 1As shown), at this time, the first abutting surface 4122 on the cover plate 41 abuts against the top surface of the base body 1; subsequently, when the cover plate 41 is driven to swing downward, the second abutting surface 4123 on the cover plate 41 gradually abuts against the top surface of the base body 1. Since the second abutting surface 4123 is convex, when the second abutting surface 4123 on the cover plate 41 abuts against the base body 1, it will move upward and simultaneously drive the expansion pin 3 to move upward until the cover plate 41 swings to the first position (as shown). Figure 6 As shown in the figure, at this time, the expansion nail 3 will expand the expansion granules 2 to fix the base body 1.

[0029] In this embodiment, there are two of each of the expanding rubber granules 2, expanding nails 3, and cover plates 41, which are respectively located on the left and right sides of the base body 1; the two cover plates 41 are connected by a connecting plate 42 to form a linkage and constitute a cover plate assembly 4.

[0030] Therefore, by setting two expansion granules 2 and expansion nails 3, the assembly firmness of the base body 1 is further improved.

[0031] Preferably, the expansion granule 2 is made of plastic, which facilitates its external expansion or repositioning; the expansion nail 3 is made of plastic or metal.

[0032] In addition, this utility model also provides a cabinet door assembly, including a door frame and the aforementioned quick-installation structure. The door frame has an installation hole, and the expansion granule 2 extends into the installation hole. Thus, when the drive cover plate 41 swings to the first position, the cone portion 31 drives the expansion portion to expand outward, and the expansion granule 2 is interference-fitted with the installation hole to fix the base body 1 to the door frame.

[0033] In summary, the quick-installation structure for a hinge base and a cabinet door assembly provided by this utility model allows for the installation of the base by first inserting the expanding rubber granules 2 into the mounting holes of the door frame. Then, the cover plate 41 is driven to swing from the second position to the first position, causing the conical portion 31 to expand the expansion portion outwards. The expanding rubber granules 2 fit tightly against the mounting holes, thereby fixing the base body 1 to the door frame. Therefore, this structure enables rapid installation of the hinge base, saving installation time and improving installation efficiency. Furthermore, it eliminates the need for fastening tools, making installation convenient.

[0034] It should be understood that the terms "top", "bottom", "inner", "outer", 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 module 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.

[0035] Furthermore, in the description of this utility model, "multiple" and "several" mean two or more, unless otherwise explicitly specified.
