Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a lightweight adjustable hinge. Background Technology

[0002] Hinges are widely used in furniture and appliances. The structure of existing hinges generally includes a hinge cup installed on the door, a hinge seat installed on the cabinet, and a transmission arm assembly hinged between the hinge cup and the hinge seat. The transmission arm assembly enables the hinge cup to open and close on the hinge seat, thereby enabling the door to open and close on the cabinet.

[0003] Furthermore, during the closing process, the door can be automatically closed. Generally, a power source for self-closing is added to the transmission arm assembly. This power source uses a torsion spring, which has a simple structure and realizes the automatic closing function of the hinge.

[0004] However, to be suitable for furniture and appliances with limited assembly space, existing hinges use thinner hinge bases (generally less than 1.0 mm thick). When these thinner hinge bases are installed in cabinets, the hinges tend to tilt, creating gaps between the front and rear points and the cabinet body. This results in uneven fit at one point and another, affecting aesthetics, reducing assembly stability, and impacting product quality. Therefore, adjustment devices with three-dimensional adjustment functions are added to these hinges. However, excessive adjustment complicates the structure, makes adjustments cumbersome, and reduces assembly efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lightweight adjustable hinge with a simple structure, reduced overall volume, and quick positioning on the cabinet, thereby improving installation efficiency, enhancing assembly accuracy, and ensuring product quality.

[0006] The purpose of this invention is achieved as follows: a lightweight adjustable hinge includes a hinge cup that is fitted to a door, a hinge seat that is fitted to a cabinet, and a transmission rod assembly hinged between the hinge cup and the hinge seat. The hinge seat is equipped with a lightweight adjustable device, which includes a base shell, an outer shell, and an adjustment frame. The base shell is equipped with a single-point limiting block for fixed-point engagement with the end of the cabinet. The single-point limiting block is located at the center of the end of the base shell. The adjustment frame slides up and down on the base shell. The hinge seat is mounted above the adjustment frame and can slide up and down on the base shell. The outer shell is fitted onto the adjustment frame and connected to the base shell, so that the outer shell and the base shell form an inner cavity for covering the hinge seat and the adjustment frame.

[0007] Based on the above optimization, the portable adjustable device further includes a first adjusting member, one end of which is rotatably connected to the adjusting frame, and the other end of which is riveted to the bottom shell, so that while the first adjusting member rotates, the adjusting frame moves up and down relative to the bottom shell.

[0008] Based on the above optimization, the left and right ends of the bottom shell are respectively provided with a first limiting slot and a second limiting slot to prevent the adjustment frame from moving left and right.

[0009] Based on the above optimization, the bottom shell is provided with a limiting shaft to restrict the up and down movement of the adjustment frame.

[0010] Based on the above optimization, the portable adjustable device further includes a second adjusting member. One end of the second adjusting member is snapped onto the adjusting frame, and the other end of the second adjusting member is threaded onto the hinge seat. Rotating the second adjusting member causes the hinge seat to move up and down relative to the adjusting frame.

[0011] Based on the above optimization, the hinge seat is provided with a limiting connector that forms with the second adjusting member to prevent the hinge seat from moving left or right. One end of the limiting connector is connected to the hinge seat, and the other end of the limiting connector is riveted to the adjusting frame.

[0012] Based on the above optimization, the front and rear sides of the adjustment frame are respectively provided with snap-fit ​​protrusions for fitting and mounting with the outer shell.

[0013] Based on the above optimization, the hinge cup is provided with a buffer group for closing buffer function. The buffer group is installed on the hinge cup, and the push rod of the buffer group is connected to the transmission rod group through the linkage frame.

[0014] The advantages of this utility model are:

[0015] 1) The hinge is positioned on the cabinet by a single-point limiting block, and the single-point limiting block is located at the middle of the end of the bottom shell. This will prevent gaps between the two points and the cabinet due to the tilt of the hinge installation, which would cause the two points to not fit properly. This makes it easier to assemble and accurately position the smaller hinge, thus improving the installation quality.

[0016] 2) The lightweight adjustable device with this structure allows for the adjustment of the upper and lower installation positions of the adjustment frame and hinge seat by rotating the first and second adjustment components. Due to the cooperation with the single-point limit block, excessive adjustment is not required, making installation convenient. It also reduces the height of the hinge seat, making the hinge thinner and more aesthetically pleasing.

[0017] 3) Since the buffer assembly is mounted on the hinge cup, it has a closed buffer function. The built-in assembly makes full use of space, resulting in a thinner and more aesthetically pleasing hinge, thus improving the quality of product use. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] According to the appendix Figures 1 to 7 As shown, the lightweight adjustable hinge of this utility model includes a hinge cup 1 that is fitted to the door, a hinge seat 2 that is fitted to the cabinet, and a transmission rod assembly 3 hinged between the hinge cup 1 and the hinge seat 2. The hinge seat 2 is equipped with a lightweight adjustable device, which includes a base shell 4, an outer shell 5, and an adjustment frame 6. The base shell 4 is provided with a single-point limiting block 7 for fixed-point engagement with the end of the cabinet, the single-point limiting block 7 being located at the center of the end of the base shell 4. The adjustment frame 6 slides up and down on the base shell 4, the hinge seat 2 is mounted above the adjustment frame 6 and can slide up and down on the base shell 4, and the outer shell 5 is engaged with the adjustment frame 6 and connected to the base shell 4, so that the outer shell 5 and the base shell 4 form an inner cavity covering the hinge seat 2 and the adjustment frame 6.

[0027] The single-point limiting block 7 is positioned on the cabinet body, and the single-point limiting block 7 is located at the middle of the end of the bottom shell 4. This prevents gaps from forming between the two points and the cabinet body due to the tilt of the hinge installation, thus avoiding a situation where one point is not properly fitted to the other. This makes it easier to assemble and accurately position the smaller hinge, improving the installation quality.

[0028] Reference Figures 1 to 7 As shown, further detailed, the portable adjustable device also includes a first adjusting member 8, one end of which is rotatably connected to the adjusting frame 6, and the other end of which is riveted to the bottom shell 4, so that while the first adjusting member 8 rotates, the adjusting frame 6 moves up and down relative to the bottom shell 4.

[0029] The bottom shell 4 is provided with a first limiting slot 41 and a second limiting slot 42 at its left and right ends, respectively, to prevent the adjustment frame 6 from moving left and right.

[0030] In addition, the bottom shell 4 is provided with a limiting shaft 9 for limiting the up and down movement of the adjustment frame 6.

[0031] In this way, since the first limiting slot 41 and the second limiting slot 42 are respectively placed at the left and right ends of the adjusting frame 6, the adjusting frame 6 can only move up and down and cannot move left and right. At the same time, in conjunction with the limiting shaft 9, when the first adjusting component 8 is rotated, the adjusting frame 6 moves up and down accordingly, and the height installation position of the hinge is adjusted during this period.

[0032] Reference Figures 1 to 7 As shown, further detailed, the portable adjustable device also includes a second adjusting member 10. One end of the second adjusting member 10 is snapped onto the adjusting frame 6, and the other end of the second adjusting member 10 is threaded onto the hinge seat 2. Rotating the second adjusting member 10 causes the hinge seat 2 to move up and down relative to the adjusting frame 6.

[0033] In practical applications, the hinge 2 is provided with a limiting connector 11 that forms with the second adjusting member 10 to prevent the hinge 2 from moving left and right. One end of the limiting connector 11 is connected to the hinge 2, and the other end of the limiting connector 11 is riveted to the adjusting frame 6.

[0034] Additionally, the front and rear sides of the adjustment frame 6 are respectively provided with snap-fit ​​protrusions 12 for fitting and mounting with the outer shell 5.

[0035] When the second adjusting component 10 is rotated, the hinge seat 2 moves up and down accordingly, thereby adjusting the hinge installation height. Since the outer shell 5 is not connected to the hinge seat 2, the bottom of the outer shell 5 is always on the same surface as the bottom of the bottom shell 4 when the hinge seat 2 is adjusted up and down, so that the outer shell 5 will not be displaced with the movement of the hinge seat 2, and gaps will be generated that affect the aesthetics of the product.

[0036] Furthermore, the hinge cup 1 is provided with a buffer group 13 for closing buffer function. The buffer group 13 is installed on the hinge cup 1, and the push rod of the buffer group 13 is connected to the transmission rod group 3 through the linkage frame.

[0037] Since the buffer assembly 13 is mounted on the hinge cup 1, it has a closing buffer function. The built-in assembly makes full use of space, resulting in a thinner and more aesthetically pleasing hinge, thus improving the quality of product use.

[0038] The above specific embodiments are only specific implementations of the present utility model with better effects. All structures that are the same as or equivalent to the portable adjustable hinge of the present utility model are within the protection scope of the present utility model.
