Description

Technical Field

[0001] This invention relates to the field of hinges, and in particular to an adjustable hinge. Background Technology

[0002] A hinge, also known as a hinge plate, is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can consist of movable components or be made of foldable materials. Hinges are mainly used on doors, windows, or cabinets; traditional hinges are mostly composed of two thin plates connected by a pin, which is not adjustable and affects usability. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable hinge that is easy to adjust and use.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] An adjustable hinge includes a connecting plate I with a limiting block in the middle, and a connecting sleeve that slides on the limiting block. Two ear plates I are fixed on the connecting sleeve. An adjusting screw I is rotatably mounted in the middle of the connecting sleeve. The adjusting screw I is threadedly connected to the limiting block. Each ear plate I has a rotating shaft, and each rotating shaft has an ear plate II. The two ear plates II are fixed on a mounting frame. Connecting plates II are connected to both sides of the mounting frame.

[0006] The mounting bracket has a C-shaped clamping plate that slides and extends near the shaft end. Both ends of the C-shaped clamping plate have locking slots. An adjusting screw II is rotated on the mounting bracket and is threadedly connected to the C-shaped clamping plate.

[0007] A spring is provided between the C-shaped plate and the mounting bracket.

[0008] The mounting bracket has grooves on both sides, and slot frames are connected to the two grooves. Connecting pipes are fixed to the outer ends of the two slot frames. The two connecting plates II slide in the two connecting pipes respectively. Adjusting screws III are rotatably inserted through the two connecting pipes. The two adjusting screws III are threadedly connected to the two connecting plates II respectively.

[0009] Each of the two slots is connected to a slider I, and a bidirectional screw rotates on the mounting bracket. The two ends of the bidirectional screw are threadedly connected to the two sliders I respectively.

[0010] The mounting bracket has a central hole running through its middle section. A worm gear is located in the middle of the bidirectional screw, inside the central hole. An adjusting worm rotates on the mounting bracket, and the adjusting worm meshes with the worm gear for transmission.

[0011] Both slotted frames have sliders II sliding on their ends away from the pivot shaft, and both mounting frames have adjusting screws IV rotating on their ends away from the pivot shaft. The two adjusting screws IV are threadedly connected to the two sliders II respectively.

[0012] Each of the adjusting screws I, III, and IV has a Phillips head or a slotted head at the end.

[0013] The ends of the adjusting worm gears are all crossheads or flatheads.

[0014] The end of the adjusting screw II has a triangular groove. Attached Figure Description

[0032] like Figure 1-13 As shown:

[0033] An adjustable hinge includes a connecting plate I 101 with a limiting block 102 in the middle, and a connecting sleeve 103 sliding on the limiting block 102. Two ear plates I 104 are fixed on the connecting sleeve 103. An adjusting screw I 106 is rotatably mounted in the middle of the connecting sleeve 103. The adjusting screw I 106 is threadedly connected to the limiting block 102. A rotating shaft 105 is rotatably mounted on each of the two ear plates I 104. An ear plate II 303 is rotatably mounted on each of the two rotating shafts 105. The two ear plates II 303 are fixed on a mounting bracket 301. Connecting plates II 409 are connected to both sides of the mounting bracket 301.

[0034] In use, the connecting plate I101 and the two connecting plates II409 are connected to two objects respectively, such as a window frame and a window sash. The relative rotation of the connecting plate I101 and the two connecting plates II409 formed by the pivot 105 causes the two objects to rotate, thus achieving the purpose of hinged connection between the two objects.

[0035] Meanwhile, by rotating the adjusting screw I106, the threaded transmission limit block 102 can slide within the connecting sleeve 103, thereby adjusting the distance between the connecting plate I101 and the rotating shaft 105 to accommodate the different thickness differences between the window frame and the window sash when closed.

[0036] like Figure 1-13 As shown:

[0037] The mounting bracket 301 has a C-shaped clamping plate 201 that slides and extends near the rotating shaft 105. Both ends of the C-shaped clamping plate 201 are provided with a locking slot 202. An adjusting screw II 302 is rotatably mounted on the mounting bracket 301 and is threadedly connected to the C-shaped clamping plate 201.

[0038] Both of the rotating shafts 105 have a round head cap at one end and a column structure at the other end. During installation, the column end is inserted into the corresponding ear plate I 104 and ear plate II 303 from the outside to the inside. The outer end is then limited by the round head cap, while the inner end, being a column, is not limited and is prone to falling off. Therefore, a C-shaped retaining plate 201 is provided. The retaining slot 202 of the C-shaped retaining plate 201 is inserted into the transverse groove of the column to form an axial limit on the inner end of the rotating shaft 105, preventing the rotating shaft 105 from falling off.

[0039] By rotating the adjusting screw II 302, the threaded C-shaped clamp 201 can slide within the mounting bracket 301, thereby causing the clamp 202 to slide on the light column. When the clamp 202 disengages from the light column, the rotating shaft 105 can be removed from the ear plate I 104 and ear plate II 303, thus forming control over the C-shaped clamp 201.

[0040] Further:

[0041] A spring 203 is provided between the C-shaped card plate 201 and the mounting bracket 301.

[0042] The elastic force of the spring 203 ensures that there is always axial stress between the threads of the C-shaped clamp 201 and the adjusting screw II 302, thereby increasing the friction between the C-shaped clamp 201 and the adjusting screw II 302 and preventing the adjusting screw II 302 from rotating automatically, which would cause the clamp 202 to detach from the light column.

[0043] like Figure 1-13 As shown:

[0044] The mounting bracket 301 has grooves 304 on both sides, and slots 402 are connected to both grooves 304. Connecting pipes 401 are fixed to the outer ends of both slots 402. Two connecting plates II 409 slide in the two connecting pipes 401 respectively. Adjusting screws III 406 are rotatably inserted through the two connecting pipes 401. The two adjusting screws III 406 are threadedly connected to the two connecting plates II 409 respectively.

[0045] By rotating the adjusting screw Ⅲ406, the threaded drive connecting plate Ⅱ409 can slide within the connecting tube 401, which in turn allows the adjusting screw Ⅰ106 to better adapt to the different thickness differences between the window frame and the window sash when closed.

[0046] like Figure 1-13 As shown:

[0047] Both slots 402 are connected to sliders I 403. A bidirectional screw 408 rotates on the mounting bracket 301, and the two ends of the bidirectional screw 408 are threadedly connected to the two sliders I 403 respectively.

[0048] By rotating the bidirectional screw 408, the two sliders I 403 can be moved closer or further apart simultaneously via the threaded drive, which in turn drives the two connecting plates II 409 to move closer or further apart via the two slot frames 402, thereby adjusting the distance between the two connecting plates II 409.

[0049] like Figure 1-13 As shown:

[0050] The mounting bracket 301 has a central hole 305 through its middle section. A worm wheel is provided in the middle of the bidirectional screw 408. The worm wheel is located inside the central hole 305. An adjusting worm 407 rotates on the mounting bracket 301. The adjusting worm 407 is meshed with the worm wheel for transmission.

[0051] By rotating the adjusting worm 407, the transmission worm wheel can be engaged, which in turn drives the bidirectional screw 408 to rotate, thereby adjusting the distance between the two connecting plates II 409.

[0052] Furthermore, by adjusting the self-locking function between the worm gear 407 and the worm wheel, the distance between the two connecting plates II 409 can be kept constant.

[0053] like Figure 1-13 As shown:

[0054] Both slotted frames 402 have sliders II 404 sliding at the ends away from the rotating shaft 105, and both mounting frames 301 have adjusting screws IV 405 rotating at the ends away from the rotating shaft 105. The two adjusting screws IV 405 are threadedly connected to the two sliders II 404 respectively.

[0055] By rotating the adjusting screw Ⅳ405, the threaded drive slider Ⅱ404 can move closer to or away from the rotating shaft 105, and then the slot frame 402 drives the connecting plate Ⅱ409 to move closer to or away from the rotating shaft 105, thereby adjusting the distance between the connecting plate Ⅱ409 and the rotating shaft 105.

[0056] Moreover, by setting two adjusting screws Ⅳ405, the distance between the two connecting plates Ⅱ409 and the rotating shaft 105 can be adjusted separately without affecting each other;

[0057] Among them, slider II 404 is limited and slidably connected to the slot frame 402, which does not affect the adjustment of the position of the slot frame 402 by the bidirectional screw 408. Slider I 403 is also limited and slidably connected to the slot frame 402, which does not affect the adjustment of the position of the slot frame 402 by the adjusting screw IV 405.

[0058] Further:

[0059] Each of the aforementioned adjusting screws I106, III406, and IV405 has a Phillips head or a slotted head at the end.

[0060] Adjusting screw I106, adjusting screw III406, and adjusting screw IV405 can be rotated using a Phillips head or flathead screwdriver.

[0061] Further:

[0062] The ends of the adjusting worm gear 407 are all crossheads or slotted heads.

[0063] The adjusting worm gear 407 can be rotated using a Phillips head or flathead screwdriver.

[0064] Further:

[0065] The end of the adjusting screw II302 is a triangular groove.

[0066] Due to the special shape of the triangular groove, a special tool is required to control the rotation of the adjusting screw II 302 to avoid arbitrary disassembly of the rotating shaft 105.
