Description

Technical Field

[0001] This utility model relates to the field of hinges or hardware accessories, specifically to a hinge assembly. Background Technology

[0002] In the prior art, hinges include fixed hinges and self-unloading hinges. Self-unloading hinges allow installers to first fix the base inside the cabinet and then detachably install the door panel onto the cabinet. The installation is highly accurate and quick, and the door panel can be easily removed from the cabinet for maintenance.

[0003] However, as Figures 1-2 As shown, existing self-unloading hinges generally include a hinge cup 10, a hinge arm 20, a self-unloading component 30, and a base 40. The self-unloading component 30 is fixed to the hinge arm 20 by rivets, and the self-unloading component 30 is provided with a rotating button 301. When installing the hinge, the front hook 302 of the self-unloading component 30 is first fastened to the front end of the base 40, and then the rear end of the self-unloading component 30 rotates around the front end to engage with the button 301, thereby fastening the hinge arm 20 and the self-unloading component 30 to the base 40. When disassembling, the button 301 is pressed to rotate, so that the rear end of the self-unloading component 30 is separated from the rear end of the base 40, and then the hinge arm 20 and the self-unloading component 30 are driven to move forward relative to the base 40, thereby removing the hinge arm 20 and the self-unloading component 30 from the base 40. However, the existing self-unloading hinge requires the front end of the self-unloading component 30 to be slid and fastened to the front end of the base 40 before installation. Then the rear end of the self-unloading component 30 rotates around the front end. The hinge arm 20 and the self-unloading component 30 can only be installed on the base 40 by sliding and rotating. The installation steps are numerous and the operation is relatively troublesome. Utility Model Content

[0005] A hinge cup, which is used for mounting on the inside of a door panel;

[0006] A hinge arm, which is rotatably connected to the hinge cup;

[0007] The self-unloading component is connected to the hinged arm, and its front end has at least one sliding protrusion, while its rear end has a first latching portion; and

[0008] A base is arranged to be mounted on the inner side of the cabinet body, and the self-unloading member is arranged to slide on the base in the front-rear direction; the front end of the base is formed with a sliding concave part matched with the sliding convex part, and the rear end of the base is formed with a second clamping part, which is elastically deformable or rotatable on the base, and the base is further provided with a pressing member for driving the second clamping part to deform or rotate;

[0009] When the self-unloading member slides on the base from front to rear, the sliding convex part slides into the sliding concave part, and after the first clamping part drives the second clamping part to elastically deform or rotate, the first clamping part is matched with the second clamping part to be clamped; when the pressing member drives the second clamping part to deform or rotate, the self-unloading member is driven to slide on the base from rear to front, so that the first clamping part is separated from the second clamping part, and the sliding convex part slides out of the sliding concave part.

[0010] In some embodiments, two sliding convex parts are arranged in the left-right direction, and the two sliding convex parts are matched with the two sliding concave parts one by one.

[0011] In some embodiments, the second clamping part is pivotally connected to the base, and the front side of the second clamping part is in the form of an inclined surface.

[0012] In some embodiments, the second clamping part is a rubber member or a silica gel member.

[0013] In some embodiments, one end of the pressing member is connected to the second clamping part, and the other end of the pressing member is located outside the base.

[0014] In some embodiments, a first guide convex part is formed on the self-unloading member, a second guide convex part is formed on the base, and the first guide convex part and the second guide convex part are matched to guide the self-unloading member to slide on the base in the front-rear direction.

[0015] In some embodiments, at least two through holes are formed on the base for the fasteners to pass through, and the at least two through holes are in the form of an ellipse or a waist circle.

[0016] In some embodiments, a first adjusting member and a second adjusting member are connected between the hinge arm and the self-unloading member;

[0017] The first adjusting member is used to adjust the position of the hinge arm and the self-unloading member in the front-rear direction.

[0019] In some embodiments, at least two mounting holes are formed on the hinge cup, and the mounting holes are used for passing through the expanded glue particles; and glue particle holes are formed on the door plate and used for inserting the expanded glue particles.

[0020] In some embodiments, the hinge cup is an integral piece made of hard plastic.

[0021] The hinge assembly has the following advantages:

[0022] When the hinge arm and the self-unloading piece are mounted on the base, the hinge arm and the self-unloading piece are driven to slide from front to back relative to the base, so that the first clamping part drives the second clamping part to elastically deform or rotate, the first clamping part slides through the second clamping part, and then the second clamping part restores to the original state and abuts against the first clamping part. The second clamping part limits the first clamping part from sliding from back to front, and the sliding convex part and the sliding concave part cooperate with each other to limit the hinge arm and the self-unloading piece from moving from bottom to top relative to the base, so that the self-unloading piece is fixed on the base. The mounting between the hinge arm, the self-unloading piece and the base can be realized by sliding the self-unloading piece relative to the base, the operation of rotating the self-unloading piece relative to the base is omitted, the operation is more convenient, the structure is firm and reliable, and the stability is good.

[0023] When the hinge arm and the self-unloading piece are detached from the base, the second clamping part no longer abuts against the first clamping part by applying an external force to the pressing piece to drive the second clamping part to elastically deform or rotate, that is, the second clamping part no longer limits the first clamping part from sliding from back to front. At this time, the hinge arm and the self-unloading piece are driven to move from back to front relative to the base, so that the hinge cup and the self-unloading piece can be detached from the base, and the operation is convenient.

[0024] Compared with the prior art self-unloading hinge which needs to be slid and rotated during installation, the hinge assembly of the utility model is more convenient and effective to disassemble and assemble, and is conducive to improving the installation efficiency.

Hinge cup 1 is used to install in the inner side of door board, for example through screw or bolt etc. fastener, hinge cup 1 is detachably installed in the inner side of door board (not shown in the drawing), hinge arm 2 is rotatably connected with hinge cup 1, specifically through the shaft connection, the connecting mode is the conventional technical means of the prior art, this place omits the superfluous repetition, self unloading piece 3 is connected with hinge arm 2, for example through rivet or adhesive etc. fixed mode is connected together, the front end of self unloading piece 3 forms at least one sliding convex part 31, sliding convex part 31 can be hook-shaped or U-shaped or V-shaped, the rear end of self unloading piece 3 forms first buckle part 32, base 4 is used to install in the inner side of cabinet body (not shown in the drawing), self unloading piece 3 can be slidably arranged on base 4 along the front and back direction, the front end of base 4 forms the sliding concave part 41 that cooperates with the buckle of sliding convex part 31, sliding concave part 41 can be formed through the stamping forming process, to make when base 4 installs in the inner side of cabinet body, sliding concave part 41 is located the surface of the inner side of cabinet body, the rear end of base 4 forms second buckle part 42, second buckle part 42 has elasticity or second buckle part 42 rotatably arranged on base 4, base 4 is also provided with the press piece 5 for driving second buckle part 42 deformation or rotation, wherein, when self unloading piece 3 slides from front to back relative to base 4, sliding convex part 31 slides into sliding concave part 41, first buckle part 32 drives second buckle part 42 elastic deformation or rotates after, first buckle part 32 and second buckle part 42 cooperate and are connected, when press piece 5 drives second buckle part 42 deformation or rotates after, drives self unloading piece 3 from back to front slide relative to base 4, to make first buckle part 32 and second buckle part 42 separate, sliding convex part 31 slides from sliding concave part 41.

[0051] Based on the above technical scheme, when the hinged arm 2 and the self-unloading part 3 are installed on the base 4, the hinged arm 2 and the self-unloading part 3 are driven to slide relative to the base 4 from front to back, so that the first clamping part 32 drives the second clamping part 42 to elastically deform or rotate, then the first clamping part 32 slides through the second clamping part 42, and then the second clamping part 42 restores to the original state and abuts against the first clamping part 32, the second clamping part 42 limits the first clamping part 32 from sliding from back to front, and the sliding protrusions 31 and the sliding recesses 41 are matched with each other to limit the hinged arm 2 and the self-unloading part 3 from moving relative to the base 4 from bottom to top, so that the self-unloading part 3 is fixed on the base 4. The utility model realizes the installation between the hinged arm 2, the self-unloading part 3 and the base 4 through the sliding of the self-unloading part 3 relative to the base 4, omits the operation of rotating the self-unloading part 3 relative to the base 4, the operation is more convenient, and the structure is firm and reliable, good stability. When the hinged arm 2 and the self-unloading part 3 are removed from the base 4, through the external force acting on the pressing part 5 to drive the second clamping part 42 to elastically deform or rotate, the second clamping part 42 no longer abuts against the first clamping part 32, that is, the second clamping part 42 no longer limits the first clamping part 32 from sliding from back to front, at this time, the hinged arm 2 and the self-unloading part 3 are driven to move relative to the base 4 from back to front, and then the hinged arm 1 and the self-unloading part 3 can be removed from the base 4, and the operation is convenient. Compared with the prior art, the hinged arm 2 and the self-unloading part 3 need to slide and rotate during installation and removal, the hinge assembly of the utility model is more convenient and effective to improve the installation efficiency.

[0052] The front-rear direction, the left-right direction and the up-down direction of the utility model are as shown in the drawings. Figures 3-4 The front-rear direction is the front-rear direction of the cabinet body facing the installer, the up-down direction is the left-right direction of the cabinet body facing the installer, and the left-right direction is the up-down direction of the cabinet body facing the installer.

[0053] In some embodiments, two sliding protrusions 31 and two sliding recesses 41 are included, the two sliding protrusions 31 are arranged at intervals along the left-right direction, and the two sliding protrusions 31 correspond to the two sliding recesses 41 one by one. The sliding protrusion 31 and the self-unloading part 3 are an integral molding structure, which can be prepared by stamping process, and the gap between the two sliding protrusions 31 can be used to install a buffer oil cylinder, so that the hinge assembly of the utility model has a buffering function. The sliding protrusion 31 can be hook-shaped, and the sliding protrusion 31 and the sliding recess 41 are buckled through concave-convex matching to limit the hinged arm 2 and the self-unloading part 3 from sliding relative to the base 4 along the up-down direction, and the first clamping part 32 and the second clamping part 42 are matched to limit the hinged arm 2 and the self-unloading part 3 from sliding relative to the base 4 along the front-rear direction.

[0054] In some embodiments, the second clamping part 42 is pivotally connected to the base 4, and the front side of the second clamping part 42 is in the shape of an inclined surface. When the first clamping part 32 abuts against the inclined surface of the second clamping part 42, the second clamping part 42 can be driven to rotate relative to the base 4, and the pressing part 5 can also rotate with the second clamping part. However, there is a large gap between the pressing part 5 and the inner side of the cabinet, so the pressing part is not interfered by the inner side of the cabinet, thereby enabling the first clamping part 32 to smoothly slide through the second clamping part 42. At this time, the second clamping part 42 returns to the original state and cooperates with the first clamping part 32 to clamp, thereby limiting the sliding of the first clamping part 32 from back to front. The second clamping part 42 returning to the original state can be achieved by the pressing part 5, or the second clamping part 42 is connected with a torsional spring. After the external force of the first clamping part 32 on the second clamping part 42 is removed, the torsional spring drives the second clamping part 42 to return to the original state.

[0055] In some other embodiments, the second clamping part 42 is a rubber part or a silica gel part. When the first clamping part abuts against the second clamping part 42, the second clamping part 42 is driven to elastically deform. After the first clamping part 32 slides through the second clamping part 42, the elastic potential energy of the second clamping part 42 drives the second clamping part 42 to return to the original state, so that the second clamping part 42 cooperates with the first clamping part to clamp.

[0056] In some embodiments, one end of the pressing part 5 is connected with the second clamping part 42, and the other end of the pressing part 5 is located outside the base 4. The one end of the pressing part 5 extending outside the hinge arm 2 can facilitate the installer to act on the pressing part 5, and drive the second clamping part 42 to elastically deform or rotate through the pressing part 5.

[0057] In some embodiments, the first guiding protrusion 33 is formed on the self-unloading part 3, and the second guiding protrusion 43 is formed on the base 4. The first guiding protrusion 33 cooperates with the second guiding protrusion 43 to guide the self-unloading part 3 to slide relative to the base 4 in the front-rear direction. When the first guiding protrusion 33 and the second guiding protrusion 43 play a guiding role, the first guiding protrusion 33 can be located inside the second guiding protrusion 43, or the second guiding protrusion 43 can be located inside the first guiding protrusion 33, which is not limited here. The purpose of matching the first guiding protrusion 33 with the second guiding protrusion 43 is to enable the sliding protrusion 31 and the sliding recess 41 to accurately cooperate with each other to slide, and to enable the first clamping part 32 and the second clamping part 42 to be clamped through the sliding from front to back, thereby improving the assembly accuracy between the self-unloading part 3 and the base 4.

[0058] In some embodiments, the base 4 is provided with at least two through holes 44 for fasteners to pass through. The at least two through holes 44 are in the shape of an ellipse or a waist circle. The through holes 44 can extend in the left-right direction, so that the base 4 can be adjusted in position relative to the inner side of the cabinet in the left-right direction, thereby enabling the hinge assembly to be adjusted in the left-right direction relative to the cabinet.

[0059] In some embodiments, the first adjusting member 6 and the second adjusting member 7 are connected between the hinge arm 2 and the self-unloading member 3; the first adjusting member 6 is used to adjust the position of the hinge arm 2 and the self-unloading member 3 along the front-rear direction; and the second adjusting member 7 is used to adjust the position of the hinge arm 2 and the self-unloading member 3 along the up-down direction. The structures of the first adjusting member 6 and the second adjusting member 7 are similar to the existing three-dimensional hinge structure, and thus the detailed description is omitted here.

[0060] In some embodiments, at least two mounting holes 11 are formed on the hinge cup 1, and the mounting holes 11 are used for the expansion adhesive particles to pass through; and the door plate is provided with adhesive particle holes (not shown in the figure) for the expansion adhesive particles to be inserted and mounted. The expansion adhesive particles are the conventional structure in the hardware fitting field, and thus the detailed description is omitted here. The hinge cup 1 is accurately mounted on the cabinet door through the pre-positioning of the expansion adhesive particles and the adhesive particle holes, so as to ensure that the hinge arm 2 and the self-unloading member 3 are accurately mounted on the base 4, and to avoid or reduce the error of the cabinet door relative to the cabinet along the left-right direction.

[0061] In some embodiments, the hinge cup 1 is an integral piece made of hard plastic, and the material can be PP, PET, or PE, etc. The manufacturing cost is low, and the efficiency is high.

[0062] The above is only the preferred embodiment of the present application, and the structure is not limited to the shape listed above. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
