Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and particularly relates to a novel ultra-thin hinge. Background Art

[0002] As an important connecting piece for furniture such as doors, windows and cabinets, the design and function of the hinge directly affect the use experience and durability of the furniture. With the diversification of modern home design, the requirements for the functionality and appearance of the hinge are getting higher and higher. Although traditional hinges can meet the basic opening and closing and adjustment requirements, there are often many problems;

[0003] For example: the three-dimensional adjustment of traditional hinges is set on one side of the cabinet body. When adjusting the left and right of the cabinet door, the overhanging distance between the hinge body and the cabinet board will increase, and the overall thickness will increase, seriously affecting the load-bearing stability and aesthetics of the hinge;

[0004] The mechanical transmission mechanism of traditional hinges is complex. Most of the damping and the rotating connecting rod are connected by at least one to multiple transmission parts. The multi-link force transmission not only increases the probability of hinge opening and closing failures and affects the service life, but also increases the overall cost and volume of the hinge, making it appear thick, heavy and bulky, and it can no longer meet the diverse needs of modern home design for hinges;

[0005] In view of the deficiencies of the prior art, the utility model proposes a novel ultra-thin hinge to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a novel ultra-thin hinge, which can form a cage structure as a whole. On this basis, when closing and opening the cabinet body, the overall service life of the hinge can be improved, and when adjusting the position of the hinge assembly surface, from the appearance, the hinge is symmetrically arranged. It not only increases the uniform force of the hinge through the symmetrical structure, improves the service life, but also improves the aesthetic degree of the appearance. During the three-dimensional adjustment process, the hinge body and the cabinet body are always closely attached, and the force-bearing is stable. The utility model uses a two-way trigger mechanism to omit multiple transmission parts between the link rotation mechanism and the damping. The structure is simple, the failure rate is low, and a large amount of space for parts is saved, so that the overall thickness of the hinge is greatly reduced, the whole machine is thin, light and beautiful, and has good aesthetic value and market prospect.

[0007] The technical solution adopted by the utility model is specifically as follows:

[0008] A novel ultra-thin hinge includes a hinge handle, one end of the hinge handle is fixed with a swing connecting piece, and a hinge locking part is rotatably connected to the end of the swing connecting piece away from the hinge handle;

[0010] A hinge arm component is assembled inside the swing connecting member. The hinge arm component is connected to the hinge locking portion. A convex portion is assembled at one end of the hinge arm component close to the damping block, forming a two-way triggering mechanism. When the hinge arm component rotates, the convex portion contacts the bevel surface at the damping block and compresses the bevel surface;

[0011] An installation housing is assembled at the top of the hinge handle. A sliding cavity is provided inside the installation housing. A notch is provided at the upper part of the installation housing. Bent limiting plates are fixed on both sides of the installation housing at the notch.

The hinge handle is located inside the sliding cavity of the installation housing and slides between the two bent limiting plates, used to limit the hinge handle to only slide back and forth at the central position inside the installation housing. A first rotating eccentric wheel is inserted between the hinge handle and the inside of the installation housing. The first rotating eccentric wheel is used to adjust the position of the hinge handle back and forth inside the installation housing, thereby adjusting the gap between the cabinet door and the cabinet body, that is, the distance back and forth;

[0012] A bottom plate is installed at the bottom of the hinge handle. A second rotating eccentric wheel is inserted between the installation housing and the bottom plate.

[0013] The installation housing is snap-connected to the bottom plate, used to enable the bottom plate to slide up and down inside the installation housing.

[0014] An assembly adjustment piece is installed at the top of the hinge locking portion. A third rotating eccentric wheel is inserted between the assembly adjustment piece and the inside of the hinge locking portion.

[0015] Two card slots are provided on the upper surface of the hinge locking portion. Corresponding card strips with the same number and position as the card slots are provided on the inner side of the assembly adjustment piece. The card strips are snapped into the card slots.

[0016] Card blocks are provided at both ends of the bottom plate. The card blocks are used to be snapped into the cavity inside the installation housing.

And when adjusting the position of the hinge assembly surface, from the appearance, the hinge is symmetrically arranged. It not only increases the uniform force of the hinge through the symmetrical structure, improves the service life, but also enhances the aesthetic degree of the appearance. By adjusting and screwing the third rotating eccentric wheel, the position of the cabinet door on the left and right sides of the cabinet body can be adjusted, thereby the gap of the door seam can be adjusted, and the left and right edges of the door can be adjusted to align with the cabinet body. By adjusting and screwing the first rotating eccentric wheel, the position of the cabinet door in the front and back of the cabinet body can be adjusted, thereby the problem that the door closes more tightly can be solved, and the distance between the cabinet door and the cabinet body in the front and back can be avoided from being too large or too small. By adjusting and screwing the second rotating eccentric wheel, the position of the cabinet door in the up and down of the cabinet body can be adjusted, the problem of the door body sinking and the problem that the upper and lower heights between two door bodies and the cabinet body are inconsistent can be solved, and during the three-dimensional adjustment process, the hinge body and the cabinet body are always closely attached, and the force bearing is stable. The utility model uses a two-way trigger mechanism to omit a plurality of transmission parts between the connecting rod rotating mechanism and the damper, has a simple structure, low failure rate, and saves a large amount of space for parts, greatly reducing the overall thickness of the hinge, making the whole machine thin and beautiful, and having good aesthetic value and market prospect.

Detailed implementation mode

[0028] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0029] As Figure 1-6 shown, a new type of ultra-thin hinge includes a hinge handle 1. One end of the hinge handle 1 is fixed with a swing connecting piece 2. The overall shape of the swing connecting piece 2 is convex, and one end of the swing connecting piece 2 away from the hinge handle 1 is rotatably connected with a hinge locking part 3, and one end of the swing connecting piece 2 away from the hinge handle 1 is bent upward so that the swing connecting piece 2 can accommodate and assemble the connecting rod structure between the hinge handle 1 and the hinge locking part 3;

[0030] This connecting rod structure is as shown in the attached Figure 4 and the attached Figure 6 shown. When the hinge locking part 3 rotates upward and bends, this connecting rod structure is used to ensure the integrity of the connection structure between the hinge handle 1 and the hinge locking part 3, and the hinge locking part 3 can move relative to the hinge handle 1, so that the hinge can be opened and closed;

[0031] The above descriptions such as the connecting rod structure are all prior arts, and corresponding structures can be found on existing hinges, and will not be elaborated in this application;

[0032] A U-shaped groove is provided inside the hinge handle 1, and an opening 16 is provided at the top of the hinge handle 1, and the opening 16 is communicated with the U-shaped groove. A damping block 15 is assembled in the U-shaped groove, and a slope is provided at one end of the damping block 15 close to the swing connecting piece 2. A flap 11 is provided inside the hinge handle 1 and close to the opening 16, and the flap 11 is connected to the damping block 15. A return spring is assembled inside the damping block 15. When the hinge is opened or closed, the hinge is driven by the return spring to move towards the closing or opening trend until it is completely closed or opened;

[0033] The interior of the swing connecting member 2 is equipped with a hinge arm member 9. The hinge arm member 9 is connected to the hinge locking portion 3. One end of the hinge arm member 9 close to the damping block 15 is equipped with a protrusion 10, forming a two-way trigger mechanism. When the hinge arm member 9 rotates, the protrusion 10 contacts the inclined surface at the damping block 15 and compresses the inclined surface, thereby applying a force to the damping block 15 to generate resistance.

[0034] The top of the hinge handle 1 is equipped with a mounting housing 4. The interior of the mounting housing 4 is provided with a sliding cavity, and an opening is provided at the upper part of the mounting housing 4. On both sides of the mounting housing 4 located at the opening, bent limiting plates 17 are fixed. The bent limiting plates 17 extend towards the inner side of the sliding cavity. The hinge handle 1 is located inside the sliding cavity of the mounting housing 4 and slides between the two bent limiting plates 17, which is used to limit the hinge handle 1 to only slide back and forth at the central position inside the mounting housing 4. The hinge handle 1 is inserted into the interior of the mounting housing 4 and is located between the two bent limiting plates 17. Thus, the hinge handle 1 can be blocked by the two bent limiting plates 17, so that the hinge handle 1 is always located between the two bent limiting plates 17 and will not shift or fall off downward. The hinge handle 1 is inserted into the interior of the mounting housing 4 and is provided with a first rotating eccentric wheel 12. The first rotating eccentric wheel 12 is used to adjust the position of the hinge handle 1 back and forth inside the mounting housing 4. When the first rotating eccentric wheel 12 rotates, the position of the hinge handle 1 back and forth inside the mounting housing 4 can be adjusted, so that the hinge handle 1 slides back and forth inside the mounting housing 4, thereby adjusting the distance between the cabinet door and the cabinet body for the function of adjusting the seam. And through the clamping connection between the hinge handle 1 and the bent limiting plate 17, the hinge handle 1 and the mounting housing 4 form a relatively independent whole. Thus, no matter how the hinge handle 1 is adjusted, it is always located at the middle position of the mounting housing 4.

[0035] The bottom of the hinge handle 1 is installed with a bottom plate 5. A second rotating eccentric wheel 13 is inserted into the interior of the mounting housing 4 and the bottom plate 5.

[0036] When it is necessary to open and close the hinge locking portion 3, the hinge locking portion 3 can be rotated to drive the internal hinge arm member 9 to rotate. The hinge arm member 9 drives the protrusion 10 to rotate, and the protrusion 10 compresses the damping block 15, thereby increasing the effect of closing buffering when the hinge rotates and ensuring the service life of the hinge.

[0037] When it is necessary to adjust the offset angle between the hinge handle 1 and the mounting housing 4, the first rotating eccentric wheel 12 can be screwed, so that the first rotating eccentric wheel 12 can rotate, thereby making the position of the mounting housing 4 adjustable on the hinge handle 1. When the second rotating eccentric wheel 13 is screwed, the position of the bottom plate 5 can be adjusted to change the position of the bottom plate 5 installed on the cabinet body.

[0038] This application can form a cage structure as a whole. On this basis, when closing and opening the cabinet body, the overall service life of the hinge can be improved. And when adjusting the position of the hinge assembly surface, from the appearance, the hinge is symmetrically arranged. It not only increases the uniform stress of the hinge through the symmetrical structure, improves the service life, but also enhances the aesthetic degree of the appearance.

[0039] Refer to the attached Figure 5 , the installation shell 4 is snap-connected with the bottom plate 5. When the hinge is perpendicular to the side plate of the cabinet body, it is used to make the bottom plate 5 slide up and down in the installation shell 4. Both ends of the bottom plate 5 are provided with clamping blocks, which are used to be clamped into the cavity inside the installation shell 4. Thus, the bottom plate 5 can be restricted inside the installation shell 4, and at the same time, the hinge handle 1 is surrounded. The settings of the installation shell 4 and the bottom plate 5 enable the bottom plate 5 to horizontally move left and right inside the installation shell 4, and can adjust the up and down movement of the adjustable door panel.

[0040] Refer to the attached Figure 1 and Figure 5 As shown in the figure, an assembly adjustment piece 6 is installed on the top of the hinge locking part 3. The assembly adjustment piece 6 and the inside of the hinge locking part 3 are inserted with a third rotating eccentric wheel 14. By screwing the third rotating eccentric wheel 14, the position of the assembly adjustment piece 6 can be adjusted, and the left and right adjustment positions of the cabinet door on the cabinet body can be changed. And when adjusting the first rotating eccentric wheel 12, the second rotating eccentric wheel 13 and the third rotating eccentric wheel 14, a spring can be selected to be assembled on them. When the spring is screwed to the appropriate position, it can reset or stabilize this state. Through the setting of the assembly adjustment piece 6, two card slots 8 are opened on the upper surface of the hinge locking part 3. The inner side of the assembly adjustment piece 6 is provided with card strips 7 with the same number and corresponding positions as the card slots 8. The card strips 7 are clamped into the inside of the card slots 8. Through this setting, the assembly adjustment piece 6 can make the card strips 7 move forward in the card slots 8 on the hinge locking part 3 through the setting of the card strips 7, and adjust the position of the assembly adjustment piece 6 on the hinge locking part 3. Both card strips 7 are arc-shaped in the direction of moving away from each other. Through this setting, after the card strips 7 are clamped into the inside of the card slots 8, they can hook the card slots 8 and limit the situation of the assembly adjustment piece 6 coming out.

[0041] By adjusting and screwing the third rotating eccentric wheel 14, the position of the cabinet door on the left and right of the cabinet body can be adjusted. Thus, the gap of the door seam can be adjusted, and the left and right edges of the door can be adjusted to align with the cabinet body. And by adjusting and screwing the first rotating eccentric wheel 12, the position of the cabinet door in the front and back of the cabinet body can be adjusted. Thus, it can be solved that the door closes more tightly, and the situation that the distance between the cabinet door and the cabinet body in the front and back is too large or too small can be avoided. By adjusting and screwing the second rotating eccentric wheel 13, the position of the cabinet door in the up and down of the cabinet body can be adjusted, and the problems of the door body sinking and the different up and down heights between the two door bodies and the cabinet body can be solved.

[0042] The purpose of the present utility model is to provide a novel ultra-thin hinge, which can integrally form a cage structure. On this basis, when closing and opening the cabinet body, the overall service life of the hinge can be improved. And when adjusting the position of the hinge assembly surface, from the appearance, the hinge is symmetrically arranged. It not only increases the uniform stress of the hinge through the symmetric structure, improves the service life, but also enhances the aesthetic degree of the appearance;

[0043] At the same time, during the three-dimensional adjustment process, the hinge body is always in close contact with the cabinet body, and the force-bearing is stable. The present utility model uses a two-way trigger mechanism to omit a plurality of transmission parts between the link rotation mechanism and the damper, with a simple structure, low failure rate, and saves a large amount of space for components, greatly reducing the overall thickness of the hinge, making the whole machine thin, light and beautiful, and having good aesthetic value and market prospects.

[0044] This hinge can adjust the distance between the opening and closing door and the cabinet, and can adjust the height of the opening and closing door to be installed. At the same time, it can slightly change the installation position of the hinge on the opening and closing door to achieve three adjustments, thereby improving the applicability of the hinge.

[0045] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
