Description

Technical Field

[0001] The present application belongs to the technical field of hinges, and in particular relates to a hinge cup of a novel cup-shaped concealed hinge and a novel cup-shaped concealed hinge. Background Art

[0002] Hinges can be used to connect two objects and allow them to rotate relative to each other. They can be widely used in construction, machinery, furniture and other fields. For example, as a connecting piece between a door body and a cabinet body, the two ends of the hinge are respectively fixed to the door body and the cabinet body, and the hinge arm of the hinge can rotate relative to the two ends connecting the door body and the cabinet body to make the door body open and close.

[0003] When adjusting the shielding area of ​​the door body through the hinge, the existing hinge usually rotates the hinge arm to lift one end of the hinge arm relative to the hinge cup, so that the door body connected to the other end of the hinge arm moves, thereby adjusting the shielding area of ​​the door body. However, after the hinge arm is lifted, the connection between the hinge arm and the cabinet body will be subjected to a large cantilever force, which may easily cause the connection between the hinge arm and the door body or the cabinet body to loosen or even fall off after long-term use, thereby shortening the service life of the hinge.

[0004] In addition, adjusting the door body by rotating the hinge arm will cause one end of the door window to lift relative to the cabinet body, that is, the angle between the door body and the cabinet body will become non-right angles, which will increase the gap between the door body and the cabinet body, and make the door body concave inward relative to the opening of the cabinet body, resulting in an uneven overall appearance.

[0005] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Summary of the invention

[0007] In a first aspect, an embodiment of the present application provides a hinge cup of a novel cup-shaped concealed hinge, comprising: A slot body shell, wherein the slot body shell is recessed inwardly to form a slide slot, the bottom of the slide slot is a first bottom plate, and both sides of the slide slot are a first guide plate and a second guide plate, and the first guide plate and the second guide plate are respectively vertically erected on the first bottom plate; A cup edge, the cup edge extending outward from the opening of the tank shell, and the cup edge is used for fixed connection with the cabinet body; A sliding mechanism, slidably mounted in the sliding groove through the first guide plate and the second guide plate, the sliding mechanism being used for being hinged to the hinge arm, and the hinge arm being used for being fixed on the door body; An offset bolt is passed through the sliding mechanism and riveted to the first bottom plate. The offset bolt can rotate axially to drive the sliding mechanism to slide horizontally on the first bottom plate along the length direction of the slide groove, so that the door body can move horizontally relative to the cabinet body.

[0008] Optionally, the cup edge includes a first cup edge and a second cup edge, the first cup edge is fixed to an end of the first guide plate away from the first bottom plate, the second cup edge is fixed to an end of the second guide plate away from the first bottom plate, and the first cup edge and the second cup edge extend toward a side away from each other.

[0010] Optionally, a fixing member is also included; The first cup edge and the second cup edge are both provided with fixing holes, and each fixing hole is used for a fixing member to pass through, so as to fix the cup edge to the cabinet body through the fixing member.

[0011] Optionally, the tank shell further includes a limiting plate, which stands vertically on the third end of the first bottom plate and spans between the first guide plate and the second guide plate.

[0012] Optionally, a third cup edge is further included, wherein the third cup edge is fixed to an end of the limiting plate away from the first bottom plate, and both ends of the third cup edge are respectively fixedly connected to the first cup edge and the second cup edge.

[0013] Optionally, the sliding mechanism comprises: A second bottom plate, arranged parallel to the first bottom plate; A first side plate, vertically fixed to a first end of the second bottom plate; A second side plate, vertically fixed to the second end of the second bottom plate; The second bottom plate, the first side plate and the second side plate are arranged to form a receiving groove, and the receiving groove is used to receive part of the hinge arm.

[0014] Optionally, a first slide rail is disposed on the inner wall of the first guide plate, and a second slide rail is disposed on the inner wall of the second guide plate corresponding to the first slide rail; The outer wall of the first side plate is provided with a first sliding block, and the outer wall of the second side plate is provided with a second sliding block; The first slider is slidably installed in the first guide rail, and the second slider is slidably installed in the second guide rail.

[0015] Optionally, a first positioning hole is formed on the first side plate, and a second positioning hole is formed on the second side plate, and the first positioning hole and the second positioning hole are arranged opposite to each other; The hinge cup of the novel cup-shaped concealed hinge also includes a first rotating shaft, which is arranged between the first positioning hole and the second positioning hole.

[0017] The above technical solution adopted in the embodiment of the present application may have the following advantages: The sliding mechanism can slide along the sliding groove of the trough shell to drive the hinge arm to slide relative to the sliding groove of the trough shell, which is equivalent to driving the hinge arm to slide horizontally relative to the cabinet body, rather than rotating the hinge arm relative to the sliding groove of the trough shell. Therefore, the relative height of the hinge arm and the sliding groove of the trough shell is always unchanged, and the relative height of the hinge arm and the cabinet body is also unchanged. Therefore, when adjusting the relative position of the sliding mechanism and the sliding groove of the trough shell, the cantilever force on the connecting part of the hinge arm and the cabinet body will not increase, so that the connection between the hinge arm and the door body and the cabinet body is not easy to loosen, thereby improving the service life of the hinge.

[0018] And because the sliding mechanism moves horizontally relative to the sliding slot of the slot shell, this adjustment is reflected in the horizontal movement of the door body, that is, what is adjusted is the horizontal sliding position of the door body in the closed state. The angle between the door body and the cabinet body remains unchanged, avoiding the appearance of obvious gaps between the door body and the cabinet body, and also avoiding the door body being concave or convex relative to the cabinet opening, resulting in an uneven overall appearance.

Therefore, without departing from the teachings of the present application, the first element, component, region, layer or part discussed below can be represented as the second element, component, region, layer or part. When the second element, component, region, layer or part is discussed, it does not indicate that the present application necessarily has the first element, component, region, layer or part.

[0025] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

The "numerical value" in the numerical interval can be any quantitative value, such as a number, a percentage, a ratio, etc. "Numerical interval" allows for broadly including quantitative intervals such as percentage intervals, ratio intervals, and ratio intervals.

[0028] Hinges can be used to connect two objects and allow them to rotate relative to each other. They can be widely used in construction, machinery, furniture and other fields. For example, as a connecting piece between a door body and a cabinet body, the two ends of the hinge are respectively fixed to the door body and the cabinet body, and the hinge arm of the hinge can rotate relative to the two ends connecting the door body and the cabinet body to make the door body open and close.

[0029] When adjusting the shielding area of ​​the door body through the hinge, the existing hinge usually rotates the hinge arm to lift one end of the hinge arm relative to the hinge cup, so that the door body connected to the other end of the hinge arm moves, thereby adjusting the shielding area of ​​the door body. However, after the hinge arm is lifted, the connection between the hinge arm and the cabinet body will be subjected to a large cantilever force, which may easily cause the connection between the hinge arm and the door body or the cabinet body to loosen or even fall off after long-term use, thereby shortening the service life of the hinge.

[0030] In addition, adjusting the door body by rotating the hinge arm will cause one end of the door window to lift relative to the cabinet body, that is, the angle between the door body and the cabinet body will become non-right angles, which will increase the gap between the door body and the cabinet body, and make the door body concave inward relative to the opening of the cabinet body, resulting in an uneven overall appearance.

[0031] Based on this, the embodiment of the present application provides a hinge cup of a novel cup-shaped concealed hinge and a novel cup-shaped concealed hinge. Based on this, the problem that the connection between the hinge arm and the door body and the cabinet body is easily loosened and falls off during long-term use, thereby shortening the service life of the hinge, and the problem that the door body is sunken inward relative to the opening of the cabinet body is alleviated. See below for details.

[0032] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited to the embodiments described herein.

[0033] See also Figures 1 to 5The embodiment of the present application provides a hinge cup of a novel cup-shaped concealed hinge, and the hinge cup of the novel cup-shaped concealed hinge includes a slot shell 10, a cup edge, a sliding mechanism 30, and an offset bolt 40. The following is a detailed description: The trough shell 10 is recessed inward to form a slide groove 17, the bottom of the slide groove 17 is a first bottom plate 11, and the two sides of the slide groove 17 are a first guide plate 13 and a second guide plate 15, and the first guide plate 13 and the second guide plate 15 are respectively vertically erected on the first bottom plate 11.

[0034] The cup edge extends outward from the opening of the tank shell 10 and is used to be fixedly connected to the cabinet. The connection between the cup edge and the cabinet provides a stable support to ensure the firmness and reliability of the hinge during use. In addition, the cup edge can help disperse the load imposed by the door body on the hinge, thereby improving the overall load-bearing capacity and reducing wear.

[0035] The sliding mechanism 30 is slidably installed in the slide groove 17 through the first guide plate 13 and the second guide plate 15. The sliding mechanism 30 is used to be hinged with the hinge arm, and the hinge arm is used to be fixed on the door body. The sliding mechanism 30 is used to slide in the slide groove 17 of the slot shell 10 to adjust the horizontal position of the door body. The hinge arm may include a connecting arm and a connecting plate, and the connecting arm and the connecting plate are connected to the sliding mechanism 30 through different rotating shafts to improve the overall flexibility of the hinge arm rotation.

[0036] The offset bolt 40 is inserted through the sliding mechanism 30 and riveted to the first bottom plate 11. The offset bolt 40 can rotate axially to drive the sliding mechanism 30 to slide horizontally along the length direction of the slide groove 17 on the first bottom plate 11, so that the door body can move horizontally relative to the cabinet body. Specifically, the offset bolt 40 can be an eccentric screw structure.

[0037] Preferably, the hinge cup of the novel cup-shaped concealed hinge according to the embodiment of the present application is suitable for wooden door profiles (ie, door bodies).

[0038] In this embodiment, since the sliding mechanism 30 slides along the slide groove 17 of the trough shell 10 to drive the hinge arm to slide relative to the slide groove 17 of the trough shell 10, it is equivalent to driving the hinge arm to slide horizontally relative to the cabinet body, rather than rotating the hinge arm relative to the slide groove 17 of the trough shell 10. Therefore, the relative height of the hinge arm and the slide groove 17 of the trough shell 10 is always unchanged, and the relative height of the hinge arm and the cabinet body is also unchanged. Therefore, when adjusting the relative position of the sliding mechanism 30 and the slide groove 17 of the trough shell 10, the cantilever force on the connecting part of the hinge arm and the cabinet body will not increase, so that the connection between the hinge arm and the door body and the cabinet body is not easy to loosen, thereby improving the service life of the hinge.

[0039] And because the sliding mechanism 30 moves horizontally relative to the slide slot 17 of the slot shell 10, this adjustment is also reflected in the horizontal movement of the door body, that is, what is adjusted is the horizontal sliding position of the door body in the closed state. The angle between the door body and the cabinet body remains unchanged, avoiding the appearance of obvious gaps between the door body and the cabinet body, and also avoiding the door body being concave or convex relative to the cabinet opening, resulting in an uneven overall appearance.

[0040] Furthermore, in this embodiment, a notch is provided on the tank shell 10 for the sliding mechanism 30 to enter the slide groove 17, and the notch is communicated with one end of the slide groove 17. The notch on the tank shell 10 allows the sliding mechanism 30 to directly enter the slide groove 17 from the notch, avoiding interference and wear caused by the sliding mechanism 30 being stuck from the side of the slide groove 17, making it easier to install or remove the sliding mechanism 30 from the tank shell 10, reducing the complexity of assembly.

[0041] When maintenance, replacement or adjustment is required, the sliding mechanism 30 can be easily taken out through the notch without removing the tank shell 10 from the cabinet.

[0042] Furthermore, in this embodiment, the cup edge includes a first cup edge 21 and a second cup edge 22, the first cup edge 21 is fixed to an end of the first guide plate 13 away from the first bottom plate 11, the second cup edge 22 is fixed to an end of the second guide plate 15 away from the first bottom plate 11, and the first cup edge 21 and the second cup edge 22 extend toward a side away from each other.

[0043] The first cup edge 21 and the second cup edge 22 are respectively fixed to the far ends of the two guide plates (the first guide plate 13 and the second guide plate 15) that are away from each other, which increases the contact area between the hinge cup and the cabinet, can provide better support, increase the stability of the overall structure, and prevent the hinge from shaking during use. In addition, by extending the cup edge outward, the load applied to the hinge can be effectively dispersed, local stress can be reduced, and durability can be improved.

[0044] Furthermore, in this embodiment, the hinge cup of the novel cup-shaped concealed hinge further comprises a fixing member. The first cup edge 21 and the second cup edge 22 are both provided with fixing holes 211, each fixing hole 211 is used to allow a fixing member to pass through, so as to fix the cup edge to the cabinet body through the fixing member.

[0045] The fixing holes 211 can help ensure accurate alignment between the cup edge and the cabinet body, avoiding unsmooth operation or damage caused by improper alignment.

[0046] There can be multiple fixing holes 211 on the first cup edge 21 and the second cup edge 22 to improve the connection strength between the cup edge and the cabinet. Specifically, the fixing member can be a structure such as an expansion screw, a rivet, a screw, a bolt, etc. When the profile fixed to the hinge cup is a wooden material, the fixing member is preferably a screw.

[0047] Furthermore, the tank shell 10 further includes a limiting plate 19 , which is vertically disposed at the third end of the first bottom plate 11 and straddles two guide plates (the first guide plate 13 and the second guide plate 15 ).

[0048] The limit plate 19 can effectively limit the movement range of the sliding mechanism 30, preventing the sliding mechanism 30 from sliding out of the slide slot 17 and causing the sliding mechanism 30 to derail. In addition, the limit plate 19 straddles between the two guide plates and can also provide additional support for the tank shell 10, increasing the structural strength and stability of the entire tank shell 10.

[0049] In one embodiment, the limiting plate 19 can be set to different thicknesses and weights according to the model of the door body, so as to provide corresponding adaptability to different models of door bodies and enhance the versatility of the hinge cup.

[0050] Furthermore, the hinge cup of the new cup-shaped concealed hinge of this embodiment also includes a third cup edge 23, which is fixed to an end of the limiting plate 19 away from the first base plate 11, and the two ends of the third cup edge 23 are fixedly connected to the first cup edge 21 and the second cup edge 22 respectively.

[0051] The third cup edge 23 connects the first cup edge 21 and the second cup edge 22 in series to form a U-shaped integrated cup edge, so that the load can be evenly distributed, the pressure of each cup edge is reduced, the service life of the hinge is extended, and the risk of deformation is reduced.

[0052] In an optional embodiment, the sliding mechanism 30 includes: a second bottom plate 31, a first side plate 33, and a second side plate 35, wherein the second bottom plate 31 is arranged parallel to the first bottom plate 11, the first side plate 33 is vertically fixed to the first end of the second bottom plate 31, and the second side plate 35 is vertically fixed to the second end of the second bottom plate 31. The second bottom plate 31, the first side plate 33, and the second side plate 35 are surrounded by a receiving groove 37, and the receiving groove 37 is used to receive part of the hinge arm.

[0053] In this embodiment, the sliding mechanism 30 is further provided with an opening connected to the receiving groove 37 to facilitate the folding of the hinge arm, reduce space occupation, and avoid interference between the hinge arm and the sliding mechanism 30 when the hinge arm is folded.

[0054] Furthermore, in this embodiment, a first slide rail 131 is disposed on an inner wall of the first guide plate 13 , and a second slide rail corresponding to the first slide rail 131 is disposed on an inner wall of the second guide plate 15 .

[0055] A first slider 331 is disposed on the outer wall of the first side plate 33, and a second slider 351 is disposed on the outer wall of the second side plate 35. The first slider 331 is slidably mounted in the first guide rail, and the second slider 351 is slidably mounted in the second guide rail.

[0056] The first slider 331 cooperates with the first guide rail, and the second slider 351 cooperates with the second guide rail, so as to prevent the second base from tilting or shaking during the sliding process, thereby ensuring that the sliding path of the second base is stable.

[0057] In practical applications, the double guide rails (first guide rail and second guide rail) and double sliders (first slider 331 and second slider 351) can ensure the stability of the hinge arm when sliding, avoiding the left-right or up-down deviation of the second base, thereby ensuring stability when adjusting the door body.

[0058] Specifically, in this embodiment, the first sliding block 331 is a rectangular block, and the shape of the second sliding block 351 can be the same as that of the first sliding block 331 to maintain the smoothness of sliding.

[0059] The rectangular block has a relatively large contact surface, which can distribute the friction force more evenly and reduce the local wear of the slider.

[0060] In other embodiments, the first slider 331 / the second slider 351 may also be in other shapes, such as circular, elliptical, etc. The first side plate 33 of the second base body may also be provided with a transverse pulley instead of the first slider 331 to reduce the friction resistance during adjustment and improve the convenience of door adjustment.

[0061] In an optional embodiment, a first positioning hole 333 is formed on the first side plate 33 , and a second positioning hole 353 is formed on the second side plate 35 . The first positioning hole 333 and the second positioning hole 353 are arranged opposite to each other.

[0062] The hinge cup of the novel cup-shaped concealed hinge also includes a first rotating shaft, which is passed between the first positioning hole 333 and the second positioning hole 353, and is also rotatably connected to the hinge arm so that the sliding mechanism 30 and the hinge arm can rotate based on the axis of the first rotating shaft.

[0063] The first rotation axis can share the torque and pressure generated during the rotation of the hinge arm, ensuring uniform force distribution during rotation. The stable connection between the positioning hole and the rotation axis ensures smooth rotation without shaking or structural damage due to uneven force distribution.

[0064] In other embodiments, the hinge arm may include a connecting arm and a connecting plate, and the connecting arm and the connecting plate are connected to the sliding mechanism 30 via different rotating shafts to enhance the overall flexibility of the hinge arm rotation.

[0065] For example, the hinge cup of the new cup-shaped concealed hinge may further include a second rotation axis, which is arranged in parallel with the first rotation axis and is arranged in a similar manner to the first rotation axis, that is, straddling between the first side plate 33 and the second side plate 35. The first rotation axis may be rotatably connected to the connecting arm of the hinge arm, and the second rotation axis may be rotatably connected to the connecting plate of the hinge arm to improve the overall flexibility of the hinge arm rotation. The structures rotatably connected to the first rotation axis and the second rotation axis may also be interchangeable.

[0066] See also Figures 6 to 8 The embodiment of the present application also provides a novel cup-shaped concealed hinge, comprising a fixing plate 300, a hinge arm 200 and a hinge cup 100 of the novel cup-shaped concealed hinge of any of the above embodiments. The fixing plate 300 is used to be fixedly connected to the cabinet, one end of the hinge arm 200 is hinged to the chassis, and the hinge cup 100 of the novel cup-shaped concealed hinge is hinged to the other end of the hinge arm 200.

[0067] That is, the hinge cup 100 of the novel cup-shaped concealed hinge is fixed to the door body, the fixing plate 300 is fixed to the cabinet body, and the hinge arm 200 serves as a medium for relative rotation between the two, thereby realizing the function of rotating the door body relative to the cabinet body.

[0068] Based on the novel cup-shaped concealed hinge of the above embodiment, an exemplary description is given. The cabinet has a double-leaf door body, that is, a door body is provided at each of the two opposite ends of the cabinet opening, and the two door bodies cooperate to cover the cabinet opening. When the gap between the door bodies is adjusted by the hinge cup 100 of the novel cup-shaped concealed hinge of the above embodiment, the two door bodies can move toward / away from each other to adjust the size of the gap between the door bodies, and the door bodies will not be sunken inward or bulged outward, resulting in an uneven appearance.

[0069] In one embodiment, the chassis may include a first chassis, a second chassis and an adjustment mechanism, the first chassis and the second chassis are both rectangular thin sheet structures, the second chassis is stacked on the first side and clamped on the first chassis, and the second chassis can provide additional support and stability for the first chassis. The adjustment mechanism may include a second eccentric bolt, the second eccentric bolt can be passed through the second chassis and riveted to the first chassis, so that the second chassis and the first chassis can be relatively moved left / right through the axial rotation of the second eccentric bolt, and then the position of the door body in the vertical direction can be adjusted, that is, the height position of the door body can be adjusted, so that the door body is more suitable for the cabinet body and the appearance is neater.
