Description

Technical Field

[0001] This utility model relates to the field of hardware hinge technology, specifically a cabinet door hinge with multi-directional adjustment function. Background Technology

[0002] Cabinet door hinges are widely used connectors in furniture, cabinets, and other fields. Their main function is to connect the cabinet door to the cabinet body and allow the door to open and close around a specific axis. As people's demands for home aesthetics and user experience continue to increase, higher requirements are being placed on the functionality of cabinet door hinges, especially their adjustability.

[0003] There are many types of cabinet door hinges available in the current technology, including common cup hinges, spring hinges, and latch hinges. These hinges perform well in basic opening and closing functions, but in actual installation and use, problems often arise regarding inaccurate alignment between the cabinet door and the cabinet body, or between different cabinet doors. For example, cabinet doors may be uneven, skewed to the left or right, protrude forward or backward, or be recessed. This not only affects the overall aesthetics but may also lead to the cabinet door not closing tightly, and may even cause friction, abnormal noise, or accelerated wear during use.

[0004] To address the aforementioned issues, some existing cabinet door hinge technologies have attempted to incorporate adjustment functions. However, these adjustment functions generally suffer from the following drawbacks: 1. Insufficient fine-tuning capabilities: Many existing hinges have limited adjustment ranges, or can only perform coarse overall displacement, lacking the ability to make millimeter-level or even sub-millimeter-level fine adjustments to cabinet doors in the horizontal, vertical, or depth directions. For example, some hinges may only offer a structure for small-range movement via elongated screw holes. This method of movement is often difficult to control precisely, and once fixed, even minor deviations are difficult to correct, resulting in imperfect alignment.

[0005] 2. The adjustment process is cumbersome and inefficient: Existing adjustment mechanisms often require repeated attempts by the operator. For example, adjusting the left and right position of a cabinet door may require loosening the mounting screws, then manually pushing or tapping the door to move it to the desired position, and then carefully tightening the screws. This method is not only time-consuming and laborious, but also particularly inconvenient for a single person to operate due to the weight of the cabinet door, and is prone to return deviation or secondary displacement. For situations requiring multi-directional (e.g., left and right, up and down, forward and backward) adjustments, the above tedious steps must be repeated, and adjusting one direction may even affect the positioning in another direction, making the overall adjustment process extremely complex and time-consuming. In addition, some adjustment mechanisms may be hidden inside the hinges or in hard-to-reach locations after installation, increasing the difficulty of adjustment.

[0006] 3. Low adjustment precision and easy damage: Due to the lack of a precise adjustment mechanism, operators often need to rely on experience and feel to make adjustments, making it difficult to guarantee adjustment precision. Repeatedly loosening and tightening screws can also easily cause thread stripping, component wear or deformation, shortening the hinge's lifespan, and even preventing the cabinet door from being securely fixed. Therefore, further improvements are necessary. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a cabinet door hinge with multi-directional adjustment capabilities that can achieve multi-directional adjustment, with a simpler and more intuitive adjustment process, and can provide high-precision fine-tuning capabilities to meet the refined needs of cabinet door installation and use.

[0008] The purpose of this utility model is achieved through the following means: a cabinet door hinge with multi-directional adjustment function, which includes a fixed seat installed on the door frame and a movable seat installed on the cabinet door. The fixed seat is provided with a first transverse guide groove, and a first horizontal plate is slidably installed in the first transverse guide groove. A first transverse adjustment mechanism is provided between the fixed seat and the first horizontal plate to drive the first horizontal plate to slide left and right in the first transverse guide groove. The movable seat is provided with a second transverse guide groove, and the second horizontal plate is slidably installed in the second transverse guide groove. A second transverse adjustment mechanism is provided between the movable seat and the second horizontal plate to drive the second horizontal plate to slide left and right in the second transverse guide groove. The first horizontal plate is also provided with a lower sleeve, and correspondingly, the second horizontal plate is provided with an upper sleeve. The two ends of the connecting pin are respectively fitted between the lower sleeve and the upper sleeve, so that the lower sleeve and the upper sleeve are hinged together as one unit.

[0009] Furthermore, the connecting pin is provided with an outwardly protruding isolation platform in the middle, and the end faces of the lower sleeve and the upper sleeve are supported on the upper and lower ends of the isolation platform.

[0010] Furthermore, the lower sleeve is provided with an internal threaded hole for adjusting height. An adjusting bolt is screwed into the internal threaded hole for adjusting height. The adjusting bolt presses against the lower end face of the connecting pin to adjust the relative height between the connecting pin and the lower sleeve.

[0011] Furthermore: a first guide rail and a second guide rail are respectively arranged on the fixed base; the first guide rail, the second guide rail and the fixed base together form a first transverse guide groove.

[0012] Furthermore, the fixed base is provided with several horizontally extending first transverse limiting grooves, and the first fixing rivet passes through the first transverse limiting grooves and connects with the first horizontal plate.

[0013] Furthermore: the first lateral adjustment mechanism includes a first lateral adjustment bolt axially fixedly mounted on a fixed base, and correspondingly: the first horizontal plate is provided with a first threaded groove that is screwed into the first lateral adjustment bolt.

[0014] Furthermore, the first axial limiting groove is recessed on the cylindrical surface of the first lateral adjusting bolt, and correspondingly, a first positioning platform is provided on the fixed base, and the first positioning platform is snapped into the first axial limiting groove.

[0015] Furthermore: a third guide rail and a fourth guide rail are arranged opposite to each other on the movable seat; the third guide rail, the fourth guide rail and the movable seat together form a second transverse guide groove.

[0016] Furthermore, the movable seat is provided with several horizontally extending second transverse limiting grooves, and the second fixing rivet passes through the second transverse limiting grooves and connects with the second horizontal plate.

[0017] Furthermore: the second lateral adjustment mechanism includes a second lateral adjustment bolt axially fixedly mounted on the movable seat, and correspondingly: the second horizontal plate is provided with a second threaded groove that is screwed to the second lateral adjustment bolt; The second lateral adjusting bolt has a recessed second axial limiting groove on its cylindrical surface. Correspondingly, the movable seat is provided with a second positioning platform, which is snapped into the second axial limiting groove.

[0018] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0019] 2. In this application, a first lateral adjustment mechanism is provided on the fixed base, and a second lateral adjustment mechanism is also provided on the movable base. This "dual-sided" lateral adjustment design greatly expands the overall lateral adjustment range of the cabinet door. In actual installation, whether there is a large initial deviation between the door frame and the cabinet door, or fine alignment is required, the adjustment mechanisms at both ends can be operated in tandem or independently, avoiding adjustment dead angles or deficiencies caused by the limitations of single-point adjustment, and ensuring that the cabinet door can be accurately aligned in the horizontal direction.

[0020] 3. An adjustable bolt is provided to adjust the relative height between the connecting pin and the lower sleeve. This also gives the cabinet door vertical adjustment capability.

[0021] 4. The adjustment process can be achieved by rotating the adjusting bolt, which has the advantages of intuitive operation, high adjustment accuracy and controllable adjustment amount.

[0022] 5. By significantly improving the adjustable range and adjustment precision, this utility model can significantly shorten the installation time of cabinet doors, reduce the installation difficulty, and at the same time ensure that the final cabinet door effect is neat and beautiful, thereby improving user satisfaction.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings. A cabinet door hinge with multi-directional adjustment function includes a fixed seat 1 installed on the door frame and a movable seat 2 installed on the cabinet door. The fixed seat 1 is provided with a first transverse guide groove 11. A first horizontal plate 3 is slidably installed in the first transverse guide groove 11. A first transverse adjustment mechanism is provided between the fixed seat 1 and the first horizontal plate 3 to drive the first horizontal plate 3 to slide left and right in the first transverse guide groove 11. The movable seat 2 is provided with a second transverse guide groove 21, and the second horizontal plate 4 is slidably installed in the second transverse guide groove 21. A second transverse adjustment mechanism is provided between the movable seat 2 and the second horizontal plate 4 to drive the second horizontal plate 4 to slide left and right in the second transverse guide groove 21. The first horizontal plate 3 is also provided with a lower sleeve 31, and correspondingly, the second horizontal plate 4 is provided with an upper sleeve 41. The two ends of the connecting pin 5 are respectively fitted between the lower sleeve 31 and the upper sleeve 41, so that the lower sleeve 31 and the upper sleeve 41 are hinged together as one unit.

[0032] In this embodiment: the fixed seat 1 is fixed on the door frame, and the movable seat 2 is fixed on the cabinet door. The two are connected by a connecting pin 5, a lower sleeve 31 and an upper sleeve 41 to form a hinge, thereby allowing the cabinet door to open and close.

[0033] On the door frame side, the first horizontal plate 3 is installed in the first horizontal guide groove 11 of the fixed base 1, and can slide left and right within the first horizontal guide groove 11 through the first horizontal adjustment mechanism. This allows the hinge part fixed to the door frame to be adjusted for lateral displacement.

[0034] On the cabinet door side, the second horizontal plate 4 is installed in the second horizontal guide groove 21 of the movable seat 2, and can slide left and right within the second horizontal guide groove 21 through the second horizontal adjustment mechanism. This allows the hinge part fixed to the cabinet door to also be adjusted for lateral displacement.

[0035] The lower sleeve 31 and the upper sleeve 41 are fixed on the first horizontal plate 3 and the second horizontal plate 4 respectively. The connecting pin 5 passes through them and hinges the two parts together to form a rotatable shaft.

[0036] In this case, independent lateral adjustment mechanisms are installed on both the door frame side and the cabinet door side, rather than adjusting only on one side. This greatly increases the range and flexibility of lateral adjustment, enabling it to handle installation scenarios with larger initial deviations. Furthermore, separating the adjustment function from the connection function, achieving independent adjustment through the horizontal plate and adjustment mechanism, facilitates subsequent refined design and functional expansion.

[0037] In one embodiment: the middle part of the connecting pin 5 is provided with an outwardly protruding isolation platform 51, and the end faces of the lower sleeve 31 and the upper sleeve 41 are supported on the upper and lower ends of the isolation platform 51.

[0038] In this embodiment: the isolation platform 51 serves as a fixed support point on the connecting pin 5, thereby limiting the positions of the lower sleeve 31 and the upper sleeve 41 on the connecting pin 5, and enabling the isolation platform 51 to withstand axial force.

[0039] When the cabinet door opens and closes, the upper and lower sleeves rotate around the connecting pin. The presence of the isolation platform 51 ensures the stability of the relative positional relationship between the two sleeves and between the sleeves and the pin, preventing axial movement and friction. Simultaneously, the isolation platform provides axial support and positioning, preventing axial movement of the upper and lower sleeves along the pin direction, enhancing the overall stability of the hinge, and better distributing and bearing the weight of the cabinet door. Furthermore, it avoids unnecessary direct friction between the sleeves and the pin or between the sleeves themselves, thereby reducing wear, extending service life, and reducing abnormal noise during opening and closing.

[0040] In one embodiment: the lower sleeve 31 is provided with an internal threaded hole for adjusting height, and the adjusting bolt 6 is screwed into the internal threaded hole for adjusting height. The adjusting bolt 6 presses against the lower end face of the connecting pin 5 to adjust the relative height between the connecting pin 5 and the lower sleeve 31.

[0041] In this embodiment: a height-adjusting internal threaded hole is pre-set inside the lower sleeve 31, and the height-adjusting bolt 6 engages with this threaded hole via a thread. When the height-adjusting bolt 6 is rotated clockwise or counterclockwise, the bolt moves upward or downward within the height-adjusting internal threaded hole. The top of the bolt presses against the lower end face of the connecting pin 5. Therefore, when the bolt moves upward, it pushes the connecting pin 5 upward; when the bolt moves downward, the connecting pin 5 will relatively descend due to gravity or the fit clearance. In this way, the relative height between the connecting pin 5 and the lower sleeve 31 can be precisely changed, thereby realizing the vertical displacement adjustment of the cabinet door. This structure has precise vertical adjustment, filling the deficiency of vertical fine adjustment in the prior art, and enabling the hinge to have complete "three-dimensional" lateral, front-back, and vertical adjustment capabilities.

[0042] In one embodiment: a first guide rail 12 and a second guide rail 13 are disposed opposite to each other on the fixed base 1; the first guide rail 12, the second guide rail 13 and the fixed base 1 together form a first transverse guide groove 11.

[0043] In this embodiment, the main structure of the fixed base 1, together with the oppositely arranged first guide rail 12 and second guide rail 13, forms a C-shaped cross-section groove, namely the first transverse guide groove 11. The corresponding shape of the first horizontal plate 3 slides into and is confined within this groove, thereby ensuring its sliding path in the transverse direction. At the same time, the design of the guide rails ensures the stability and accuracy of the horizontal plate's path during sliding, avoiding skewing or jamming.

[0044] In one embodiment: the fixed base 1 is provided with a plurality of first transverse limiting grooves 32 extending laterally, and the first fixing rivet 33 passes through the first transverse limiting grooves 32 and is connected to the first horizontal plate 3.

[0045] When the first horizontal plate 3 slides within the guide groove, the rivet moves within the limiting groove. The length of the limiting groove determines the maximum sliding distance of the horizontal plate. The presence of the rivet prevents the horizontal plate from detaching from the fixed base during adjustment.

[0046] In one embodiment: the first lateral adjustment mechanism includes a first lateral adjustment bolt 7 axially fixedly mounted on the fixed base 1, and correspondingly: the first horizontal plate 3 is provided with a first threaded groove 34 that is screwed to the first lateral adjustment bolt 7.

[0047] When the first transverse adjusting bolt 7 is rotated, since the bolt itself cannot move axially, its thread will drive the first threaded groove 34 connected to it and the first transverse plate 3 connected to it to slide laterally in the first transverse guide groove 11 along the axial direction of the bolt.

[0048] In this embodiment, the threaded drive mechanism provides extremely high adjustment accuracy. Each rotation of the bolt can bring about a controllable, minute lateral displacement, achieving precise positioning at the millimeter or even sub-millimeter level.

[0049] Furthermore, adjustment can be completed simply by rotating the bolt with a tool, without needing to loosen other fasteners, greatly simplifying the adjustment process. At the same time, the threaded connection has a certain self-locking capability, ensuring stability once the adjustment is complete and the position is not easily misaligned.

[0050] In one embodiment: the first lateral adjusting bolt 7 has a first axial limiting groove 71 recessed on its cylindrical surface, and correspondingly, the fixing seat 1 has a first positioning platform 14, which is snapped into the first axial limiting groove 71.

[0051] In this embodiment: when the bolt is installed in place, the first positioning platform 14 is embedded and locked in the first axial limiting groove 71, thereby preventing the first transverse adjusting bolt 7 from axially moving during rotation and ensuring that it can only rotate purely.

[0052] In one embodiment: a third guide rail 22 and a fourth guide rail 23 are arranged opposite to each other on the movable seat 2; the third guide rail 22, the fourth guide rail 23 and the movable seat 2 together form a second transverse guide groove 21.

[0053] In one embodiment: the movable seat 2 is provided with a plurality of laterally extending second lateral limiting grooves 42, and the second fixing rivet 43 passes through the second lateral limiting grooves 42 and is connected to the second horizontal plate 4. In one embodiment: the second lateral adjustment mechanism includes a second lateral adjustment bolt 8 axially fixedly mounted on the movable seat 2, and correspondingly: the second horizontal plate 4 is provided with a second threaded groove 44 that is screwed to the second lateral adjustment bolt 8; The second lateral adjusting bolt 8 has a recessed second axial limiting groove 81 on its cylindrical surface. Correspondingly, the movable seat 2 is provided with a second positioning platform 24, which is snapped into the second axial limiting groove 81.

[0054] In the above embodiments, the implementation of the second lateral adjustment mechanism is similar in principle to that of the first lateral adjustment mechanism, and will not be described in detail here. This symmetrical and precise fine-tuning capability achieves the same high-precision and convenient bolt-type lateral adjustment on the cabinet door side as on the door frame side, further improving the overall lateral adjustment range and precision. At the same time, the uniformity of the adjustment methods on both sides makes it easier for the operator to master and use.

[0055] In summary, the cabinet door hinge with multi-directional adjustment function provided by this utility model has the core working principle of achieving precise displacement control of the cabinet door in the horizontal and vertical directions through independent and non-interfering multi-dimensional adjustment mechanisms, thereby ensuring that the cabinet door can be installed in the best usage state.

[0056] Among them, the principle of lateral adjustment is: This hinge features two main components—a fixed base 1 mounted on the door frame and a movable base 2 mounted on the cabinet door—each with an independent lateral adjustment mechanism, thus providing dual lateral adjustment capability.

[0057] Lateral adjustment of the door frame side: The first horizontal plate 3 is slidably installed in the first lateral guide groove 11 of the fixed base 1. The key is the first lateral adjustment mechanism, the core of which is the first lateral adjustment bolt 7. This bolt is axially fixed to the fixed base 1 and cannot move back and forth, but it can rotate freely. The first horizontal plate 3 is provided with a first threaded groove 34 that matches the bolt thread. When the operator rotates the first lateral adjustment bolt 7, the rotational movement of the bolt is converted into the linear movement of the first horizontal plate 3 through thread engagement, driving the first horizontal plate 3 to slide left and right or back and forth in the guide groove. Its axial limiting groove and the snap-fit ​​of the positioning table ensure the pure rotational movement of the bolt, thereby ensuring the stability and accuracy of the adjustment.

[0058] Lateral adjustment on the cabinet door side: The principle is similar to that on the door frame side. The second horizontal plate 4 is slidably installed in the second lateral guide groove 21 of the movable seat 2. It is also axially fixed to the movable seat 2 by the second lateral adjustment bolt 8 in the second lateral adjustment mechanism, and screwed into the second threaded groove 44 on the second horizontal plate 4. Rotating the second lateral adjustment bolt 8 drives the second horizontal plate 4 to slide left and right or back and forth in the guide groove. The axial limiting groove 81 of the second bolt, in cooperation with the second positioning table 24, also ensures the reliability of the adjustment.

[0059] Collaborative Operation: These two independent lateral adjustment mechanisms can be operated independently or in conjunction. For example, when the cabinet door needs to move significantly to the left, the lateral mechanisms on both the door frame and door sides can be adjusted simultaneously to quickly reach the target position. Conversely, when only minor adjustments are needed, the adjusting bolts on either side can be precisely operated to achieve millimeter-level alignment. This dual lateral adjustment greatly enhances the adjustment range and flexibility, adapting to various complex installation conditions.

[0060] Vertical adjustment principle: This hinge also incorporates an independent vertical height adjustment function. This function is achieved through the cooperation of the height adjustment bolt 6 and the connecting pin 5. The height adjustment bolt 6 is screwed into the height adjustment internal thread hole at the bottom of the lower sleeve 31, and its top end contacts the lower end face of the connecting pin 5. When the operator rotates the height adjustment bolt 6, the bolt rises or falls within the threaded hole. The rise of the bolt pushes the connecting pin 5 upward, causing the entire hinge point, i.e., the cabinet door, to rise vertically; conversely, the fall of the bolt allows the connecting pin 5 to fall relatively. The isolation platform 51 in the middle of the connecting pin 5 provides a stable bearing point for the upper and lower sleeves, ensuring smooth and stable vertical adjustment. This bolt-type vertical adjustment enables fine-tuning of the cabinet door's height, solving the problem of uneven cabinet door heights.

[0061] Connection and limiting principle: The fixed seat 1 and movable seat 2 of the hinge are respectively connected to the corresponding horizontal plates, such as the first guide rail 12, the second guide rail 13, the third guide rail, and the fourth guide rail, to form guide grooves, ensuring that the horizontal plates slide smoothly along the preset direction.

[0062] The first lateral limiting groove 32 on the fixed seat, the second lateral limiting groove 42 on the movable seat, the first fixing rivet 33, and the second fixing rivet 43 cooperate to effectively prevent the horizontal plate from detaching from the main body while allowing a certain range of sliding, thus improving the reliability and safety of the hinge.

[0063] In addition, the lower sleeve 31 and the upper sleeve 41 are fixed to the first horizontal plate 3 and the second horizontal plate 4 respectively, and are hinged together by the connecting pin 5 to form the axis for opening and closing the cabinet door. This structure ensures that the adjustment mechanism does not affect the basic opening and closing function of the cabinet door.

[0064] In summary, the working principle of this utility model cabinet door hinge lies in the fact that by setting independent bolt-driven horizontal adjustment mechanisms on the door frame side and the cabinet door side, as well as an independent bolt-driven vertical height adjustment mechanism, it achieves all-round, high-precision, stepless micro-adjustment of the cabinet door in the horizontal X and Y directions and the vertical Z direction. This combination of multi-dimensional adjustment allows the cabinet door to be adjusted to the optimal state of perfect alignment with the cabinet body with great convenience and precision during installation. It effectively solves the pain points of limited adjustment range, cumbersome operation, and insufficient precision in existing technologies, greatly improving installation efficiency and the aesthetics and functionality of the cabinet door.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
