Description

Technical Field

[0001] The invention relates to the technical field of furniture hardware accessories, in particular to a hinge assembly. Background Art

[0002] The hinge consists of three parts: the hinge head (hinge cup), the body, and the base. Hinges are divided into three types according to the installation method: fixed installation, self-unloading (quick release), and punch-free. The hinge head, body, and base cannot be separated in the fixed hinge, while the body and base can be removed in the self-unloading hinge. Among them, the body and base of the existing self-unloading hinge are disassembled and assembled by snap-fitting, and the snap-fit ​​connection between the body and the base is achieved by fasteners. For example, in the "A Hinge Assembly" disclosed in Chinese patent application number CN202222335812.6, the hinge assembly includes a first body, a second body, a base, a clamping member and an elastic member. The base is used to be fixed on the inner wall of the cabinet, and the base is respectively formed with a first buckle position and a second buckle position on both sides along the first direction; the clamping member is pivotally connected to the second body; the elastic member is arranged inside the second body, one end of the elastic member is connected to the second body, and the other end of the elastic member is connected to the clamping member. The clamping member is formed with a clamping portion that is buckled with the first buckle position, and the bottom of the end of the second body away from the clamping member is formed with a hook portion that is buckled with the second buckle position. The clamping member is pressed by external force to rotate relative to the second body, and the elastic member is deformed by force. When the interconnected second body and the first body are fixedly installed on the inner wall of the cabinet, the base is first fixed to the inner wall of the cabinet by screws or adhesives, and then the pressing part of the pressing member is aligned with the first buckle position and the hook portion is aligned with the second buckle position. External force acts on the first body, and the pressing part drives the elastic member to compress, so that the pressing part is lightly displaced, so that the hook portion and the second buckle position are mutually buckled. After the first buckle position slides over the pressing part, the compressed elastic member drives the pressing part to reset and buckle on the first buckle position, so that the second body is buckled on the base by buckling. When the second body and the first body need to be removed from the base, the pressing member is pressed to stretch the elastic member, drive the pressing part to lightly displace, release the buckle effect between the pressing part and the second buckle position, and then drive the second body to move relative to the base, further release the buckle effect between the hook portion and the first buckle position, so that the second body is separated from the base, and then the first body and the second body are separated from the base.

[0003] However, when the user takes clothes out of the cabinet, the clothes or hands may accidentally touch and squeeze the clamping part, thereby releasing the snapping effect between the clamping part and the second snapping position, thereby causing the first body and the second body to separate from the base, and then causing the door panel and the cabinet to be easily disassembled. There is a risk of the door panel falling off, which poses a risk of use and has low safety. Summary of the invention

[0004] In order to solve the technical problem that the hinge assembly in the prior art has the risk of door panels falling off, the first aspect of the present invention provides a connection assembly, comprising:

[0005] A hinge cup, the hinge cup being used to be fixed on the inner side of the cabinet door;

[0006] A main body component, the main body component is rotatably connected to the hinge cup, the front end of the main body component is formed with at least one hook portion, the rear end of the main body component is formed with at least one buckling portion, and the buckling portion has an inclined guiding surface and a clamping surface; and

[0007] A base component, the base component includes a fastener, an elastic member and a base body fixed on the inner wall of the cabinet, the front end of the base body is formed with a first engaging position that is engaged with the hook portion, the fastener is formed with a second engaging position that is engaged with the engaging surface, the fastener is pivotally connected to the base body so that the fastener can be rotated and switched between the first position and the second position; the elastic member is connected between the fastener and the base body;

[0008] The main body component and the base component can be detachably connected; when the main body component is connected to the base component, the hook is buckled in the first engaging position, the inclined guide surface pushes against the second engaging position, and an external force drives the rear end of the main body component so that the second engaging position passes over the inclined guide surface and is engaged with the engaging surface;

[0009] When the main body component is separated from the base component, external force presses the fastener to rotate relative to the seat body so that the second engaging position is separated from the engaging surface, and the rear end of the main body component can be separated from the seat body. After the external force is removed, the elastic member drives the fastener to return to its original position.

[0010] In some embodiments, the body component comprises:

[0011] A first body, the first body being rotatably connected to the hinge cup;

[0012] A second body, wherein the second body is provided with at least one first adjustment portion, and when the first adjustment portion is adjusted alone, the first body can be translated and lifted only in the up and down directions relative to the second body; and

[0013] The self-unloading bar, the hook portion and the buckling portion are respectively arranged at the front and rear ends of the self-unloading bar; the self-unloading bar is provided with a second adjustment portion, when the second adjustment portion is adjusted alone, the first body and the second body can only move along the front and rear direction relative to the self-unloading bar.

[0014] In some embodiments, one end of the first adjusting portion is connected to the first body, and the other end of the first adjusting portion is threadedly connected to the second body;

[0015] When the first adjusting portion is driven to rotate relative to the second main body, the first main body can be translated and lifted only along the up and down directions relative to the second main body.

[0016] In some embodiments, at least one positioning portion is formed on the self-unloading strip, and a positioning hole that cooperates with the positioning portion is formed on the seat body.

[0017] In some embodiments, an operating hole for operating the second adjusting portion is formed on the first body, and a decorative cover is detachably connected to the operating hole.

[0018] In some embodiments, the first body includes a first left side panel and a first right side panel, and the first left side panel and / or the first right side panel are formed with at least one folding portion;

[0019] The second body includes a second left side plate and a second right side plate, and the second left side plate and / or the second right side plate are in contact with the folding portion, so that the first body can be translated and lifted only in the up-and-down direction relative to the second body.

[0020] In some embodiments, the seat body includes at least three mounting holes, at least two of the mounting holes are arranged in sequence along the left-right direction, and at least one of the mounting holes extends along the left-right direction to be elliptical or oval in shape.

[0021] In some embodiments, when viewed in the up-down direction, each of the mounting holes is located outside a projection area of ​​the main body component on the base.

[0022] In some embodiments, the seat body is provided with two rotating parts that are spaced apart from each other, the buckle is pivotally connected to the rotating parts via a pivot, and a limiting part is formed on the front side of the rotating parts;

[0023] The elastic member is a torsion spring, which is passed through the pivot shaft, one end of which is in contact with the buckle, and the other end of which is in contact with the seat body;

[0024] Wherein, the limiting portion is used to limit the rotation range of the buckle so that the buckle maintains abutment with one end of the torsion spring.

[0025] In some embodiments, a clearance recess is formed on the rear end edge of the seat body to cooperate with the fastener, and a friction portion is formed on the upper surface of the fastener, and the friction portion includes a convex point or a convex block or a convex strip or a groove.

[0026] Based on the above technical solution, the hinge assembly of the present invention has the following beneficial effects compared with the prior art:

[0027] When the main body component is connected to the base component, the front end of the main body component is engaged with the front end of the base component through the hook and the first engaging position, and the rear end of the main body component rotates around its front end so that the inclined guide surface of the engaging portion is engaged with the second engaging position, and an external force (such as pressing) is applied to the rear end of the main body component so that the fastener rotates and the elastic member generates elastic potential energy. When the inclined guide surface passes through the second engaging position of the fastener, the elastic member releases the elastic potential energy to drive the fastener to rotate so that the second engaging position is engaged with the engaging surface, thereby limiting the movement of the rear end of the main body in the up-and-down direction, so that the main body component is connected with the base component. The assembly process does not require repeated engagement and positioning, and the inclined guide surface of the engaging portion is engaged with the rotating fastener, so that the rear end of the main body component is engaged with the rear end of the base component, which is labor-saving and quick, and the operation is simple and convenient.

[0028] When the main part and the base part are separated from each other, an external force (such as pressing) presses the fastener to rotate relative to the base body to release the clamping action between the second clamping position and the clamping surface, and the elastic member generates elastic potential energy. At this time, the rear end of the main part rotates around its front end to separate the rear end of the main part from the base body. After the external force is removed, the elastic member releases the elastic potential energy and drives the fastener to rotate to its original position. At the same time, the front end of the main part moves relative to the front end of the base part, so that the front end of the main part and the rear end of the main part are separated from each other. The separation of the main part and the base part is completed. The operation is simple and convenient, and no additional tools are required. At the same time, since the external force used during disassembly is a pressing force, not a lifting or hooking force, it is completely different from the prior art in which the pressing member is set on the main part. During use, the hinge assembly of the present invention will not cause the main part and the base part to be separated due to clothing being buckled on the fastener. It is reliable and safe to use, and the risk of the door panel falling off is prevented, with high safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] like Figure 1-Figure 15As shown, the present invention provides a hinge assembly, including a hinge cup 1, a main body part 2 and a base part 3, wherein the hinge cup 1 is used to be fixed on the inner side of the cabinet door; the main body part 2 is rotatably connected to the hinge cup 1, the front end of the main body part 2 is formed with at least one hook portion 231, and the rear end of the main body part 2 is formed with at least one buckling portion 232, the buckling portion 232 has an inclined guide surface 232a and a clamping surface 232b; the base part 3 includes a fastener 31, an elastic member 32 and a seat body 33 for being fixed on the inner wall of the cabinet body, the front end of the seat body 33 is formed with a first clamping position 331 that is matched with the hook portion 231, the fastener 31 is formed with a second clamping position 311 that is matched with the clamping surface 232b, and the fastener 31 is pivotally connected to the seat body 33 so that the fastener 31 can be connected to the second clamping position 311 at the first position. The fastener 31 can be switched between the positions; an elastic member 32 is connected between the fastener 31 and the seat body 33; wherein the main body part 2 and the base part 3 can be detachably connected; when the main body part 2 is connected to the base part 3, the hook portion 231 is snapped into the first snapping position 331, and the inclined guide surface 232a is pressed against the second snapping position 311, and an external force drives the rear end of the main body part 2 so that the second snapping position 311 passes over the inclined guide surface 232a and is snapped onto the snapping surface 232b; when the main body part 2 and the base part 3 are separated, an external force presses the fastener 31 to rotate relative to the seat body 33 so that the second snapping position 311 is separated from the snapping surface 232b, and the rear end of the main body part 2 can be separated from the seat body 33, and after the external force is removed, the elastic member 32 drives the fastener 31 to return to its original position.

[0054] It should be noted that the installation method of the hinge cup 1 and the inner side of the cabinet door is the same as the prior art, and the details are omitted here. The number of hooks 231 and the first engaging positions 331 are the same, and the positions correspond one to one, so that each hook 231 can be smoothly matched and engaged with each first engaging position 331. As a specific embodiment, a notch 338 is formed in the front central part of the seat body 33 by stamping or other forming processes, the first engaging position 331 is located in the central part of the front end of the seat body 33, and the first engaging position 331 is a concave part. The first engaging position 331 is formed by a stamping process and is in an inverted U shape, so that the part of the seat body 33 corresponding to the first engaging position 331 is upwardly protruding, so that the hook 231 can be hooked on the first engaging position 331 from front to back, thereby realizing the quick buckle of the hook 231 and the first engaging position 331, and the disassembly is convenient, and at the same time, the rear end of the main body part 2 can rotate with the front end of the main body part 2. Furthermore, the number of hooks 231 is two, the number of first engaging positions 331 is also two, the two first engaging positions 331 are both in an inverted U shape, the two first engaging positions 331 are connected by a U-shaped connecting section 339, the portion of the seat body 33 corresponding to the connecting section 339 is concave downward, and the portion of the seat body 33 corresponding to the first engaging positions 331 is convex upward, so that the front end of the seat body 33 is a structure with high sides and low middle, which is convenient for the two hooks 231 to accurately hook on the two first engaging positions 331, thereby improving assembly efficiency. Furthermore, the front side of the connecting section 339 extends forward to form a positioning protrusion 3310, and the two sides of the positioning protrusion 3310 are spaced from the two sides of the notch 338 to form a mountain shape, so that the two hooks 231 are further accurately hooked on the two first engaging positions 331.

[0055] Therefore, when the main body part 2 is connected with the base part 3, the front end of the main body part 2 and the front end of the base part 3 are engaged with the first engaging position 331 through the hook part 231, and the rear end of the main body part 2 rotates around its front end so that the inclined guide surface 232a of the engaging part 232 engages with the second engaging position 311, and an external force (for example, the external force is pressing, specifically pressing with fingers) is applied to the rear end of the main body part 2 so that the fastener 31 rotates and the elastic part 32 generates elastic potential energy. When the inclined guide surface 232a passes through the second engaging position 311 of the fastener 31, the elastic part 32 releases the elastic potential energy to drive the fastener 31 to rotate, so that the second engaging position 311 is engaged with the engaging surface 232b, thereby limiting the movement of the rear end of the main body in the up and down directions, so that the main body part 2 and the base part 3 are connected together. The assembly process does not require repeated matching and positioning. The inclined guiding surface 232a of the snap-fitting portion 232 cooperates with the rotating fastener 31, so that the rear end of the main body component 2 and the rear end of the base component 3 are matched and snap-fitted, which is labor-saving, fast, simple and convenient to operate.

[0056] When the main body part 2 and the base part 3 are separated from each other, an external force (for example, pressing) presses the fastener 31 to rotate relative to the base body 33 to release the clamping action between the second clamping position 311 and the clamping surface 232b, and causes the elastic member 32 to generate elastic potential energy. At this time, the rear end of the main body part 2 rotates around its front end to separate the rear end of the main body part 2 from the base body 33. After the external force is removed, the elastic member 32 releases the elastic potential energy and drives the fastener 31 to rotate to its original position. At the same time, the front end of the main body part 2 moves relative to the front end of the base part 3, so that the front end of the main body part 2 and the rear end of the main body part 2 are separated from each other. At this point, the separation of the main body part 2 and the base part 3 is completed. The operation is simple and convenient, and no additional tools are required. At the same time, since the external force used during disassembly is a pressing force instead of a pulling or hooking force, it is completely different from the prior art in which the pressing part is set on the main part 2. During use, the hinge assembly of the present invention will not cause the main part 2 and the base part 3 to be separated due to clothes being fastened on the fastener 31. It is reliable and safe to use, prevents the risk of the door panel falling off, and has high safety.

[0057] In some embodiments, Figure 1-Figure 15As shown, the main body 2 includes a first main body 21, a second main body 22 and a self-unloading bar 23. The first main body 21 is rotatably connected to the hinge cup 1, for example, by an axis structure to achieve rotation; the second main body 22 is provided with at least one first adjustment portion 24. When the first adjustment portion 24 is adjusted alone, the first main body 21 can be translated and lifted only in the up-down direction relative to the second main body 22; the hook portion 231 and the buckle portion 232 are respectively provided at the front and rear ends of the self-unloading bar 23; the self-unloading bar 23 is provided with a second adjustment portion 25. When the second adjustment portion 25 is adjusted alone, the first main body 21 and the second main body 22 can be moved only in the front-back direction relative to the self-unloading bar 23. By adjusting the first adjustment portion 24 alone, the first main body 21 can be driven to be translated and lifted only in the up-down direction relative to the second main body 22, and the first main body 21 will not tilt or move in the left-right direction or the front-back direction relative to the second main body 22, ensuring that the position of the cabinet door is adjusted only in the left-right direction relative to the cabinet body. In addition, by adjusting the second adjusting part 25 alone, the first body 21 and the second body 22 can be driven to move only in the front-to-back direction relative to the self-unloading bar 23, while the first body 21 and the second body 22 will not move in the up-down direction or left-to-right direction relative to the self-unloading bar 23, thereby adjusting the position of the cabinet door relative to the cabinet body in the front-to-back direction. The first adjusting part 24 adjusts the first body 21 to move only in the up-down direction relative to the second body 22, and the second adjusting part 25 adjusts the first body 21 and the second body 22 to move only in the front-to-back direction relative to the self-unloading bar 23, ensuring that the first body 21 does not affect or interfere with each other during the up-down direction adjustment and the front-to-back direction adjustment process, reducing the difficulty of adjustment, and improving the accuracy and convenience of adjusting the position of the cabinet door relative to the cabinet body. Furthermore, during the adjustment process of the first adjustment part 24 and / or the second adjustment part 25, the inclination angle of the hinge cup 1 relative to the base part 3 will not change, that is, within any adjustment range of the first adjustment part 24 and / or the second adjustment part 25, the minimum closing angle and the maximum opening angle of the hinge cup 1 relative to the base part 3 (or the cabinet body) remain unchanged, so that the user's experience will not be changed due to the adjustment of the first adjustment part 24 and the second adjustment part 25 when using the cabinet door and the cabinet body.

[0058] It should be noted that the term "independent adjustment" generally describes that when the first adjustment portion 24 is adjusted, the first body 21 moves only in the up-down direction relative to the second body 22, and when the second adjustment portion 25 is adjusted, the first body 21 and the second body 22 move only in the front-back direction relative to the dump bar 23;

[0059] It also shows that when the first adjustment part 24 is adjusted, the cabinet door will not be displaced in other directions except the up-down direction relative to the connection surface of the base component 3; or when the second adjustment part 25 is adjusted, the cabinet door will not be displaced in other directions except the front-back direction relative to the connection surface of the bottom mounting component;

[0060] It also shows that when adjusting the up-and-down direction of the first body 21 relative to the second body 22, it is only necessary to adjust the first adjustment part 24 without adjusting the second adjustment part 25; or when adjusting the front-and-back directions of the first body 21 and the second body 22 relative to the dump bar 23, it is only necessary to adjust the second adjustment part 25 without adjusting the first adjustment part 24.

[0061] In some embodiments, Figure 1-Figure 3 As shown, one end of the first adjusting portion 24 is connected to the first main body 21, and the other end of the first adjusting portion 24 is threadedly connected to the second main body 22; when the first adjusting portion 24 is driven to rotate relative to the second main body 22, the first main body 21 can only be translated and lifted along the up-down direction relative to the second main body 22. The first adjusting portion 24 and the first main body 21 are fixed by riveting, and a continuous external thread structure is provided on the outer peripheral side of the first adjusting portion 24, and an internal thread structure is formed on the second main body 22, so that the first adjusting portion 24 can rotate relative to the first main body 21; when the first adjusting portion 24 rotates relative to the first main body 21, the threads between the first adjusting portion 24 and the second main body 22 cooperate to enable the second main body 22 to be translated and lifted along the up-down direction relative to the first main body 21.

[0062] In some embodiments, a part of the second adjustment part 25 may be, for example, an eccentric piece or a sheet-like body in the shape of a Loehler triangle, another part of the second adjustment part 25 may be rotatably disposed on the self-unloading bar 23, and the second main body 22 may be formed with a matching part 223. During the rotation of the second adjustment part 25 relative to the self-unloading bar 23, the second adjustment part 25 and the matching part 223 may be matched and abutted, driving the second main body 22 to slide relative to the self-unloading bar 23 in the front-to-back direction, thereby causing the first main body 21 and the second main body 22 to move relative to the self-unloading bar 23 in the front-to-back direction. In other embodiments, the second adjustment part 25 is a fastener with external threads, and a slide groove extending in the front-to-back direction is formed on the second main body 22. The second adjustment part 25 is threadedly connected to the self-unloading bar 23 after passing through the slide groove. When the second adjustment part 25 and the second main body 22 are relatively loosened, the second main body 22 and the self-unloading bar 23 can move in the front-to-back direction.

[0063] In some embodiments, at least one positioning portion 23 is formed on the self-unloading strip 23, and a positioning hole 333 is formed on the seat body 33 to cooperate with the positioning portion 23. The positioning portion 23 is, for example, a convex block or a convex structure, and the number can be one or more. For example, the number of the positioning portions 23 is two, and the two positioning portions 23 are arranged at intervals along the vertical direction. Correspondingly, the number of the positioning holes 333 is also two, and the two positioning holes 333 are arranged at intervals along the vertical direction and are connected with the two positioning portions 23, so that when the rear end of the main body part 2 rotates relative to the front end, the positioning portion 23 cooperates with the positioning hole 333 to position, so that the buckling portion 232 of the main body part 2 and the fastener 31 are smoothly buckled, and the assembly is more stable and reliable.

[0064] In some embodiments, an operating hole 211 for operating the second adjustment portion 25 is formed on the first body 21. The operating hole 211 is detachably connected to a decorative cover 27. The operating hole 211 is used for passing tools such as a screwdriver or a wrench so that the tool can act on the second adjustment portion 25 to adjust the second adjustment portion 25 so that the first body 21 and the second body 22 can be adjusted only along the front-to-back direction relative to the self-unloading bar 23.

[0065] In some embodiments, the first body 21 includes a first left side plate 212 and a first right side plate 213, and the first left side plate 212 and / or the first right side plate 213 are formed with at least one folding portion 214; the second body 22 includes a second left side plate 221 and a second right side plate 222, and the second left side plate 221 and / or the second right side plate 222 are in contact with the folding portion 214, so that the first body 21 can only be translated and lifted along the up-and-down direction relative to the second body 22. The folding portion 214 can be, for example, a columnar structure, and one end of the folding portion 214 is plugged into the first left side plate 212 or the first right side plate 213. The folding portion 214 can be, for example, a convex or convex point or block structure, and one end of the folding portion 214 can form an integrated structure with the first left side plate 212 or the first right side plate 213. The number of the folding portions 214 can be one or more, for example, the number of the folding portions 214 is at least two, and the at least two folding portions 214 respectively limit the first adjustment portion 24 from moving along the front-and-back direction relative to the first body 21 or the second body 22. For example, there are two folding portions 214 respectively located at the two ends of the first left plate 212 or the first right plate 213 along the front-to-back direction. The two folding portions 214 respectively cooperate with, abut or fit against the second left plate 221 or the second right plate 222, thereby limiting the movement of the first adjustment portion 24 relative to the first body 21 or the second body 22 along the front-to-back direction.

[0066] In some embodiments, the seat body 33 includes at least three mounting holes 334, at least two mounting holes 334 are sequentially arranged in the left-right direction, and at least one mounting hole 334 extends in the left-right direction to be elliptical or oval. The mounting holes 334 are used for threaded fasteners to pass through, and the seat body 33 is fixed to the inner side wall of the cabinet by the threaded fasteners to achieve a detachable connection. One of the mounting holes 334 is elliptical or oval, which allows the threaded fastener to move in the mounting hole 334, so that the seat body 33 can move in the up-down direction, so that the height of the cabinet door can be adjusted relative to the cabinet in the up-down direction.

[0067] In some embodiments, when viewed in the up and down direction, each mounting hole 334 is located outside the projection area of ​​the main body component 2 on the seat body 33 , which facilitates installation and prevents the main body component 2 from interfering with the position of the mounting hole 334 .

[0068] In some embodiments, the seat 33 is provided with two rotating parts 335 arranged at intervals relative to each other, the fastener 31 is pivotally connected to the rotating part 335 through a pivot, and a limiting part 336 is formed on the front side of the rotating part 335; the elastic member 32 is a torsion spring, which is passed through the pivot, one end of the torsion spring is abutted against the fastener 31, and the other end of the torsion spring is abutted against the seat 33; wherein the limiting part 336 is used to limit the rotation range of the fastener 31, so that the fastener 31 and one end of the torsion spring are kept in abutment. The two ends of the torsion spring are respectively kept in abutment with the fastener 31 and the seat 33, when the external force drives the fastener 31 to rotate, the torsion spring can be squeezed so that the torsion spring generates a torsion force, and after the external force is released, the torsion force of the torsion spring can drive the fastener 31 to reset, so that at least one side of the fastener 31 is abutted against the limiting part 336, and the limiting part 336 effectively prevents the fastener 31 from coming out, ensuring that the fastener 31 can be buckled with the buckling part 232.

[0069] In some embodiments, Fig.15 As shown, the rear edge of the seat body 33 is formed with a clearance recess 337 that cooperates with the fastener 31, and the upper surface of the fastener 31 is formed with a friction portion (not shown in the figure), which includes a convex point or a convex block or a convex strip or a groove. The clearance recess 337 can increase the rotation range of the fastener 31 relative to the seat body 33, making it easier to remove the main body component 2 from the base component 3. The friction portion increases the contact surface and contact friction force of pressing the fastener 31, making it easier to press.
