Description

Technical Field

[0001] This invention relates to the technical field of hinges, specifically to a hinge locking device for an upward-opening door and a locking method thereof. Background Technology

[0002] Patent No. 2025219566560 proposes a lift-up door hinge with quick-installation auxiliary positioning function. Through the design of an auxiliary installation block and a matching locking structure, it can be positioned and installed even when the cabinet top panel has a protruding edge. However, another application scenario for lift-up doors is the installation of the hinge on an aluminum frame door. Existing locking structures, which connect to wooden doors using self-tapping screws, cannot directly lock the aluminum frame using a threaded connection method to ensure its connection strength. Therefore, a new connecting locking structure is needed to meet user requirements.

[0003] In addition, traditional locking structure solutions can lock aluminum frame doors by designing adapter plates and threaded connections, but this design has certain drawbacks such as insufficient connection strength and insufficient service life.

[0004] Therefore, it is necessary to design a locking structure to ensure the installation and locking of the upward-opening door hinge for the aluminum frame door and to ensure its connection strength. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an upward-opening door hinge locking device and a locking method thereof. The device has a simple structure, is easy to assemble, has high locking strength, a wide range of applications, improves connection stability, and ensures the quality of product use.

[0006] The objective of this invention is achieved as follows: A hinge locking device for a lift-up door includes a hinge assembly for opening and closing a profile door within a cabinet. The hinge assembly has a fixed base mounted on the cabinet. The hinge assembly's swing arm is equipped with a locking component adapted for installation on the profile door. The locking component includes a lift-up assembly and a connecting base assembly. The lift-up assembly includes a lift-up accessory base, a primary connecting screw, a lift-up accessory slider, and a secondary connecting screw. The lift-up accessory sliders are respectively engaged on the left and right sides of the profile door and adapted to be embedded in the corresponding lift-up accessory bases. The secondary connecting screws are distributed on the lift-up accessory bases and threaded to the corresponding lift-up accessory sliders, thus fixing the lift-up accessory sliders to the lift-up accessory bases. The connecting base assembly is mounted on the lift-up accessory base via primary connecting screws. The swing arm of the hinge assembly is adapted to be fastened to the connecting base assembly.

[0007] Based on the above optimization, the upward-flipping accessory base has at least three longitudinally distributed mounting holes, and the primary connecting screws are distributed on the connecting base assembly and are installed in accordance with the corresponding mounting holes.

[0008] Based on the above optimization, at least two notches are respectively opened on the left and right inner sides of the profile door body for matching and mounting with the sliding block of the upward-flipping accessory.

[0009] Based on the above optimization, the upward-flipping accessory slider is provided with anti-slip texture for connecting with the inner side of the profile door body.

[0010] Based on the above optimization, two connecting holes are opened on one side of the flip-up accessory base for mounting the flip-up accessory slider. The connecting holes are provided with guide posts for mounting the flip-up accessory sliders in the same direction. The flip-up accessory sliders are provided with guide grooves for sliding connection with the guide posts.

[0011] Based on the above optimization, the guide groove is positioned at a 45-degree angle relative to the center of the upward-flipping accessory slider.

[0012] Based on the above optimization, the two ends of the connecting base assembly are respectively provided with a first annular groove and a second annular groove, and the swing arm of the hinge assembly is provided with an elastic buckle and a positioning rivet. The positioning rivet is engaged in the first annular groove, and then the elastic buckle rotates around the positioning rivet towards the second annular groove and is elastically locked in the second annular groove.

[0013] A locking method includes an upward-opening door hinge locking device, wherein the operation steps of the upward-opening door hinge locking device are as follows: Step 1: At least two notches are pre-cut on the left and right sides of the profile door body; Step 2: Pass the left-side up-flip accessory sliders through the corresponding notches and align the anti-slip texture of the up-flip accessory sliders with the left inner wall of the profile door, so that the up-flip accessory sliders are respectively locked onto the left side of the profile door. Then, rotate the secondary connecting screws to align the left-side up-flip accessory base with the left outer wall of the profile door. Step 3: Pass the right-side up-flip accessory sliders through the corresponding notches and align the anti-slip texture of the up-flip accessory sliders with the right inner wall of the profile door, so that the up-flip accessory sliders are respectively locked onto the right side of the profile door. Then, rotate the secondary connecting screws to align the right-side up-flip accessory base with the right outer wall of the profile door. Step 4: Arrange the connecting base components symmetrically on the left and right sides, and install them by matching them with the primary connecting screws and the upward-facing accessory base; Step 5: Install the positioning rivet of the swing arm of the hinge assembly into the first annular groove of the connecting base assembly. Then rotate the elastic buckle of the hinge assembly around the positioning rivet towards the second annular groove. When the elastic buckle contacts the second annular groove, the elastic lock is forced onto the second annular groove by the gravity of the profile door, so that the profile door and the hinge are locked together.

[0014] The advantages of this invention are: 1) The locking assembly using this structure, through the locking of the upturn assembly assembly and the connecting base assembly with the profile door body, solves the problem that the original wooden locking connection structure cannot be directly used in the application scenario of profile door body. Furthermore, the upturn assembly assembly and the profile door body are locked together by secondary connecting screws, which increases the contact surface with the inner wall of the profile door body, thereby increasing the pressure between the upturn assembly assembly and the profile door body, which is conducive to achieving the strength of the locking connection.

[0015] 2) Through the structural cooperation between the secondary connecting screw and the upward-flipping accessory slider, the engagement length of the secondary connecting screw can be rotated to adapt to the specifications of different profile door wall thicknesses, which is convenient to operate and helps to expand the product's application range.

[0016] 3) The structure of the sliding block of the flip-up accessory, combined with the anti-slip texture, increases the stability of the locking connection. Attached Figure Description

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] According to the appendix Figures 1 to 11 As shown, the upward-opening door hinge locking device of the present invention includes a hinge assembly 1 for opening and closing a profile door 3 onto a cabinet 2, and a fixing seat of the hinge assembly 1 is mounted on the cabinet 2. The swing arm of the hinge assembly 1 is provided with a locking component adapted for mounting on the profile door 3. The locking component includes an upward-opening assembly and a connecting base assembly 4. The upward-opening assembly includes an upward-opening accessory base 5, a primary connecting screw 6, an upward-opening accessory slider 7, and a secondary connecting screw 8. The upward-opening accessory slider 7 is respectively snapped onto the left and right sides of the profile door 3 and adapted to be embedded in the corresponding upward-opening accessory base 5. The secondary connecting screws 8 are distributed on the upward-opening accessory base 5 and threaded with the corresponding upward-opening accessory slider 7, so that the upward-opening accessory slider 7 is fixedly connected to the upward-opening accessory base 5. The connecting base assembly 4 is mounted on the upward-opening accessory base 5 by the primary connecting screw 6, and the swing arm of the hinge assembly 1 is adapted to be fastened to the connecting base assembly 4.

[0030] The locking assembly using this structure, through the locking of the upturn assembly assembly, the connecting base assembly 4 and the profile door 3, solves the problem that the original wooden locking connection structure cannot be directly used in the application scenarios of the profile door 3. Furthermore, the upturn assembly assembly and the profile door 3 are locked together by the secondary connecting screws 8, which increases the contact surface with the inner wall of the profile door 3, thereby increasing the pressure between the upturn assembly assembly and the profile door 3 and facilitating the achievement of the strength of the locking connection.

[0031] Reference Figures 1 to 11 As shown, in further detail, the upturned accessory base 5 has at least three longitudinally distributed mounting holes 51, and the primary connecting screws 6 are distributed on the connecting base assembly 4 and are installed in accordance with the corresponding mounting holes 51.

[0032] Furthermore, the left and right inner sides of the profile door body 3 are respectively provided with at least two notches 51 for engaging with the upward-flipping accessory slider 7. One side of the upward-flipping accessory base 5 is provided with two connecting holes 52 for mounting the upward-flipping accessory slider 7. Each connecting hole 52 is provided with a guide post 53 for mounting the upward-flipping accessory slider 7 in the same direction. Each upward-flipping accessory slider 7 is provided with a guide groove 72 for sliding connection with the guide post 53.

[0033] That is, the slider 7 of the flip-up accessory can be embedded into the interior of the flip-up accessory base 5 through the guide groove 72 along the guide post 53 of the flip-up accessory base 5, and the engagement length of the rotating secondary connecting screw 8 can be adapted to the frame wall thickness specifications of different profile door bodies 3, which is conducive to expanding the application range of the product.

[0034] The guide groove 72 is positioned at a 45-degree angle relative to the center of the flip-up accessory slider 7. This ensures that the two flip-up accessory sliders 7 on the left or right side of the flip-up assembly face the same direction, aligning with the guide groove 72 of the flip-up accessory base 5. If the orientations are inconsistent, the guide groove 72 and the guide post 53 will not match. In practical applications, the "L" or "R" markings on the left or right flip-up assembly will also be reversed. This helps prevent variations in the components, ensures consistency in the openings of the profile door body 3, and guarantees installation efficiency for the user.

[0035] Furthermore, the upward-flipping accessory slider 7 is provided with anti-slip texture 71 that can be connected to the inner side of the profile door body 3, which helps to increase the connection stability of the locking device.

[0036] Reference Figures 1 to 11 As shown, further detailed, the two ends of the connecting base assembly 4 are respectively provided with a first annular groove 41 and a second annular groove 42. The swing arm of the hinge assembly 1 is provided with an elastic buckle 11 and a positioning rivet 12. The positioning rivet 12 is engaged in the first annular groove 41, and then the elastic buckle 11 rotates around the positioning rivet 12 toward the second annular groove 42 and is elastically locked in the second annular groove 42.

[0037] Reference Figures 1 to 11 As shown, a locking method includes an upward-opening door hinge locking device, the specific operation steps of which are as follows: Step 1: At least two notches 31 are pre-cut on the left and right sides of the profile door body 3; Step 2: Pass the left-side up-flip accessory sliders 7 through the corresponding notches 31, and align the anti-slip texture 71 of the up-flip accessory sliders 7 with the left inner wall of the profile door 3, so that the up-flip accessory sliders 7 are respectively locked on the left side of the profile door 3. Then, rotate the secondary connecting screws 8 to align the left-side up-flip accessory base 5 with the left outer wall of the profile door 3. Step 3: Pass the right-side up-flip accessory sliders 7 through the corresponding notches 31, and align the anti-slip texture 71 of the up-flip accessory sliders 7 with the right inner wall of the profile door 3, so that the up-flip accessory sliders 7 are respectively locked onto the right side of the profile door 3. Then, rotate the secondary connecting screws 8 to align the right-side up-flip accessory base 5 with the right outer wall of the profile door 3. Step 4: Arrange the connecting base assembly 4 symmetrically on the left and right sides, and install it by matching it with the first-level connecting screw 6 and the upward-turning accessory base 5; Step 5: Install the positioning rivet 12 of the swing arm of the hinge assembly 1 into the first annular groove 41 of the connecting base assembly 4, and then rotate the elastic buckle 11 of the hinge assembly 1 around the positioning rivet 12 toward the second annular groove 42. When the elastic buckle 11 contacts the second annular groove 42, the elastic buckle is forced onto the second annular groove 42 by the gravity of the profile door body 3, so that the profile door body 3 and the hinge are locked together.

[0038] The upward-flipping assembly component using this structure works in conjunction with the connecting base component 4 and the hinge component 1. The structure is simple, easy to assemble, increases the locking strength, and ensures the quality of the product.

[0039] The above specific embodiments are merely specific implementations of the present invention with better effects. Any structure that is the same as or equivalent to the upward-opening door hinge locking device and the locking method of the present invention is within the protection scope of the present invention.
