Description

Technical Field

[0001] This utility model relates to the technical field of hinges, and in particular to a hinge that is easy to assemble and disassemble. Background Technology

[0002] Currently, hinges are commonly used to connect doors to door frames. A typical hinge structure includes a base fixed to the door frame, a base fixed to the door body, and a hinge arm connecting the two bases. The hinge arm is pivotally connected to the bases at both ends, thereby enabling the door to rotate and open. However, in existing technology, the pivots are usually designed to be difficult to disassemble. Therefore, when installing the door, it is usually necessary to first pre-install the hinge's door frame end base into the corresponding mounting groove in the door frame, and then align and fix the pre-drilled mounting groove on the door body with the other base. Since the hinge's door frame end base is fixed at this point, the hinge's adjustable range of motion is limited, making it difficult to precisely align the door body mounting groove with the base. Furthermore, when tightening the connecting screws, the operating space is limited by the hinge arm and the door frame itself, making this installation step quite inconvenient. Utility Model Content

[0029] Reference Figures 1 to 4 According to a first aspect embodiment of the present invention, a hinge that is easy to assemble and disassemble includes a first base 100, a rotating arm 200, and a second base 300. The rotating arm 200 is pivotally connected to the first base 100, and the rotation axis of the rotating arm 200 is in the vertical direction. The rotating arm 200 has a first mounting hole 210 that extends horizontally through it. The second base 300 has a connecting arm 400 that can overlap the rotating arm 200, and the connecting arm 400 has a second mounting hole 410 that corresponds to the first mounting hole 210. The first mounting hole 210 and the second mounting hole 410 are used for fastener connection. During installation, the first base 100 with the rotating arm 200 can be connected to the door frame, and the second base 300 with the connecting arm 400 can be connected to the door body. Disassembling the hinge and installing it separately to the door body and the door frame reduces the positional restrictions during installation and makes installation more convenient. When installing the door body onto the door frame, the connecting arm 400 can be overlapped onto the rotating arm 200. Then, fasteners are inserted into the first mounting hole 210 and the second mounting hole 410 and locked. Since the first mounting hole 210 and the second mounting hole 410 extend horizontally, there is ample installation space when locking the fasteners, and they are not obstructed by the rotating arm 200, making installation relatively convenient. It is conceivable that the first base 100 can also be connected to the door body, and the second base 300 can be connected to the door frame. The aforementioned hinge structure can also be used for windows, cabinet doors, and other similar items.

[0030] Specifically, both the first base 100 and the second base 300 can extend vertically, as can the rotating arm 200 and the connecting arm 400. The rotating arm 200 rotates around a vertical pivot, while the connecting arm 400 is fixed. The first mounting hole 210 and the second mounting hole 410 can be formed in the thickness direction of the rotating arm 200 and the connecting arm 400. During installation, the rotating arm 200 and the connecting arm 400 can overlap each other, and the fastener can be a bolt. The first mounting hole 210 or the second mounting hole 410 can be a threaded hole for bolt thread connection. During installation, the first base 100 and the second base 300 are on both sides of the rotating arm 200 and the connecting arm 400, and the operating direction of the locking bolt is horizontal and towards the rotating arm 200, without interfering with the first base 100, the second base 300, the door body, and the door frame, making installation more convenient.

[0031] Reference Figures 1 to 4 In some embodiments of this utility model, the second mounting hole 410 has a mounting opening 411 that penetrates the end of the connecting arm 400 away from the second base 300. Specifically, the first mounting hole 210 may be provided with internal threads. When connecting the rotating arm 200 and the connecting arm 400, the bolt can be pre-connected to the first mounting hole 210. The bolt can form a positioning structure that protrudes on the rotating arm 200. Then, it can be inserted and positioned from the side through the mounting opening 411, so as to align the first mounting hole 210 and the second mounting hole 410. Positioning is more convenient. After positioning, tightening the bolt completes the connection.

[0032] Reference Figures 1 to 2 In some embodiments of this utility model, at least two first mounting holes 210 are provided, and the first mounting holes 210 are spaced apart in the vertical direction. At least two second mounting holes 410 are provided, one of which has a mounting opening 411 that penetrates the end of the connecting arm 400 away from the second base 300. Specifically, there can be two first mounting holes 210 spaced apart in the vertical direction, and similarly, there can be two second mounting holes 410 on the connecting arm 400 spaced apart in the vertical direction. The mounting opening 411 can be provided only for one of the second mounting holes 410 to reduce processing costs. The first mounting holes 210 may have internal threads, and the fastener can be a bolt. During installation, bolts can be pre-installed in the first mounting holes 210 corresponding to the second mounting holes 410 with mounting openings 411. The bolts can form a positioning structure. When connecting the rotating arm 200 and the connecting arm 400, the bolts can be inserted and positioned from the side through the mounting openings 411 so that the two second mounting holes 410 are aligned with the first mounting holes 210. After alignment, the bolts are tightened, and bolts are installed in the other set of mounting holes. The cooperation of the two sets of mounting holes makes the hinge connection more secure.

[0033] Understandably, both second mounting holes 410 can be provided with mounting openings 411. During installation, bolts can be pre-installed in both first mounting holes 210. During mating, both mounting openings 411 are simultaneously engaged with the corresponding bolts for installation.

[0034] Reference Figures 1 to 4 In some embodiments of this utility model, the first base 100 includes a base 110 and an adjusting seat 120. The rotating arm 200 is pivotally connected to the adjusting seat 120. The base 110 is provided with a first adjusting hole 112, and the adjusting seat 120 is provided with a second adjusting hole 122 corresponding to the first adjusting hole 112. The first adjusting hole 112 and the second adjusting hole 122 are used for fastener connection. One of the first adjusting hole 112 and the second adjusting hole 122 is a slotted hole extending along the Z-axis direction, and the other is a round hole. Specifically, the base 110 can be fixedly connected to the door frame. The first adjusting hole 112 of the base 110 can be a round hole with internal threads, while the second adjusting hole 122 of the adjusting seat 120 can be a slotted hole. Bolts pass through the second adjusting hole 122 and connect to the first adjusting hole 112. Due to the slotted hole structure, the adjusting seat 120 and the base 110 can move and adjust relative to each other along the Z-axis direction to adjust the relative height position of the door and the door frame. After adjustment, the bolts can be tightened.

[0035] Reference Figure 2 In some embodiments of this utility model, the base 110 is provided with a protruding limiting block 111, and the adjusting seat 120 is provided with a limiting bolt 121 opposite to the limiting block 111 in the Z-axis direction. The limiting bolt 121 is threadedly connected to the adjusting seat 120, and the axial direction of the limiting bolt 121 is parallel to the Z-axis direction. Rotating the limiting bolt 121 can abut against the limiting block 111. Specifically, the adjusting seat 120 and the base 110 can move relative to each other in the Z-axis direction and are fixed by bolt connection. However, since the rotating arm 200 is connected to the door body and bears force through the connecting arm 400, the adjusting seat 120 will sink relative to the base 110 under long-term use. Therefore, the base 110 can be provided with a limiting block 111 that protrudes in the horizontal direction, and the adjusting seat 120 can be provided with a limiting bolt 121 located above the limiting block 111. Tightening the limiting bolt 121 can make the limiting bolt 121 move up and down in the Z-axis direction. After the adjusting seat 120 is positioned in the Z-axis direction, the limiting bolt 121 can be adjusted to abut against the limiting block 111. By abutting and limiting the limiting bolt 121, the lowering of the adjusting seat 120 can be restricted to a certain extent, which can reduce the frequency of later adjustments and meet the needs of long-term use.

[0036] It is understandable that the limiting seat and adjusting bolt can be symmetrically arranged above and below the center line of the first base 100Z axis so that after the hinge is reversed and installed, one of the adjusting bolts can still abut against the limiting block 111.

[0037] Reference Figure 2 In some embodiments of this utility model, one of the first mounting hole 210 and the second mounting hole 410 is a waist-shaped hole extending along the X-axis, and the other is a round hole. Specifically, the round hole may have internal threads, and the fastener is a bolt. The bolt passes through both the waist-shaped hole and the round hole, so that the rotating arm 200 and the connecting arm 400 can move and adjust relative to each other along the X-axis, thereby adjusting the distance between the door body and the door frame.

[0038] Reference Figures 1 to 2 In some embodiments of this utility model, the swing arm 200 has a curved portion 220 and a straight portion 230. One end of the curved portion 220 is pivotally connected to the first base 100, and the other end is connected to the straight portion 230. The straight portion 230 is provided with a first mounting hole 210. The connecting arm 400 is a plate-like structure, and the straight portion 230 overlaps with the connecting arm 400. Specifically, the curved portion 220 can be bent approximately 90°, allowing the swing arm 200 to achieve a clearance effect when the door is closed, while the straight portion 230 and the plate-like connecting arm 400 can directly overlap and cooperate. It is understood that the swing arm 200 can be a one-piece structure, which can reduce the number of parts and save production costs.

[0039] Reference Figure 2 In some embodiments of this utility model, a first toothed plate structure 231 is provided on the side of the straight plate portion 230 that overlaps with the connecting arm 400, and the connecting arm 400 is provided with a second toothed plate structure 420 that meshes with the first toothed plate structure 231. Specifically, the first toothed plate structure 231 has vertical teeth closely arranged in the horizontal direction, and the second toothed plate structure 420 has the same. During the overlapping engagement, the meshing teeth can restrict the relative movement of the rotating arm 200 and the connecting arm 400 in the X-axis direction. Compared with fastening by friction, the limiting effect of mutual meshing of the toothed plates is better.

[0040] Reference Figure 2 In some embodiments of this utility model, the connecting arm 400 is detachably mounted on the second base 300. Manufacturing the connecting arm 400 and the second base 300 separately facilitates the demolding of parts, and the connecting arm 400 can be connected to the second base 300 by bolts.

[0041] Reference Figure 2In some embodiments of this utility model, the second base 300 is provided with a third adjustment hole 310, and the connecting arm 400 is provided with a fourth adjustment hole 430 that corresponds to the third adjustment hole. The third adjustment hole 310 and the fourth adjustment hole 430 are used for fastener connection. One of the third adjustment hole 310 and the fourth adjustment hole 430 is a slotted hole extending along the Y-axis, and the other is a round hole. Specifically, the third adjustment hole 310 can be a threaded round hole, and the fourth adjustment hole 430 can be a slotted hole. Bolts can pass through the fourth adjustment hole 430 and be threadedly connected to the third adjustment hole 310. Through the slotted hole, the connecting arm 400 can move relative to the second base 300 along the Y-axis to adjust its position, so as to adjust the front and rear directions of the door body and the door frame. After the adjustment is completed, the bolts can be tightened.
