Description

Technical Field

[0001] This utility model belongs to the field of door handle technology, specifically relating to an adjustable angle aluminum alloy door handle. Background Technology

[0002] Door handles serve both decorative and functional purposes. They are categorized by material, including alloy, ceramic, solid wood, metal, glass, crystal, and plastic. Door handles are also classified by style, such as single-hole spherical, single-hole strip, or Japanese, modern Chinese, and European styles. People can choose the material according to their needs to achieve the desired opening and closing effect of the door.

[0003] Patent document CN220869036U discloses an adjustable door and window handle. Through a groove on the base surface, a slider allows the first and second door handles to move in an arc, thus changing the handle's adjustment angle. A bolt securely connects the second door handle to the groove, and a threaded sleeve ensures a stable connection between the second door handle and the slider, preventing accidental detachment and increasing handle stability. The groove's curvature is concentric with the connecting plate, allowing the first and second door handles to move in an arc within the groove, facilitating opening doors and windows from different angles (left and right) and reducing the likelihood of slippage or jamming.

[0004] The aforementioned adjustable door and window handles can solve the corresponding technical problems, but when targeting users of different heights, it is necessary to first rotate the nut to separate the first and second handles, and then rotate the second door handle to open and close the door and window. The operation process is relatively cumbersome and inconvenient to use, resulting in reduced efficiency in the door opening and closing process. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable angle aluminum alloy door handle to solve the technical defects of existing adjustable angle door and window handles.

[0027] See appendix Figures 1-3 As shown in the figure, an adjustable angle aluminum alloy door handle according to an embodiment of the present invention includes a handle body 100, on which a locking component 200 and an unlocking component 300 are provided. The handle body 100 includes an L-shaped mounting plate 110, and a handle 120 is rotatably connected to one side of the mounting plate 110. The locking component 200 includes a limiting member 210 disposed on the side of the mounting plate 110 facing the handle 120, and a pin 220 is provided on the handle 120. The limiting member 210 and the pin 220 are engaged to fix the angle of the handle 120. The unlocking component 300 is disposed on the handle 120 and is used to operate the pin 220 to achieve the unlocking and resetting effects. The unlocking component 300 includes a pressing member 310 and a linkage member 320 disposed on the handle 120. The pressing member 310 and the pin 220 are connected by the linkage member 320.

[0028] When using the adjustable angle aluminum alloy door handle described above, the mounting plate 110 is installed on the door leaf. By holding the handle 120 and pressing the button 311 with the thumb, the button 311 causes the pressure plate 312 and the lower toothed plate 322 to move synchronously within the inner cavity of the handle 120. The spring 313 contracts under force, and the lower toothed plate 322 slides towards the support column 130 through the support plate 314. The lower toothed plate 322 drives the gear 321 to rotate, and the gear 321 drives the upper toothed plate 322 to move towards the support plate 314. The upper toothed plate 322 drives the movable plate 221, the insertion post 222, and the baffle 223 to move synchronously until the insertion post 222 disengages from the inner cavity of the insertion hole 212, thus unlocking the handle 120. At this time, the handle 120 can be rotated, causing the handle 120 to rotate the unlocking component 300, the pin 220, and the support column 130.

[0029] When the user is short, simply rotate the handle 120 around the support column 130 on the lower half of the mounting plate 110 to adjust the grip angle of the handle 120. When the user is tall, first rotate the handle 120 around the support column 130 to the upper half of the mounting plate 110, and then rotate the handle 120 on the upper half of the mounting plate 110 to adjust the grip angle of the handle 120. Thus, the handle 120 at different angles and heights provides a personalized ergonomic user experience for people of different heights.

[0030] In order to achieve the angle adjustment of the handle 120, in this embodiment: a support column 130 is fixedly connected to one end of the handle 120 facing the mounting plate 110, and the other end of the support column 130 away from the handle 120 is rotatably connected to the mounting plate 110 through a pivot. A limiting member 210 is provided on the surface of the support column 130. The support column 130 can realize the connection between the mounting plate 110 and the handle 120, and at the same time, it allows the handle 120 to rotate about the pivot between the support column 130 and the mounting plate 110.

[0031] In this embodiment of the utility model, the limiting member 210 includes a ring 211 movably sleeved on the surface of the support column 130. The ring 211 is fixedly connected to one side of the mounting plate 110. The ring 211 has a plurality of equidistantly distributed insertion holes 212 on the side facing the handle 120.

[0032] To improve the safety of opening and closing the door, the latch 220 includes a movable plate 221 movably connected to the handle 120. A pin 222 is fixedly connected to the side of the movable plate 221 facing the ring 211. One end of the pin 222 is engaged with the inner cavity of the corresponding insertion hole 212. Through the cooperation of the limiting member 210 and the latch 220, the handle 120 can be positioned, so that the handle 120 can be stably maintained at a certain angle to prevent the hand from slipping suddenly due to the wobbling of the handle 120 during the opening and closing of the door, which could cause the body to lose balance and fall.

[0033] In order to enable the movable plate 221 to move horizontally stably, a through groove 121 is provided at the top of the handle 120. The bottom of the movable plate 221 passes through the through groove 121 into the inner cavity of the handle 120 and is connected to the unlocking component 300. The inner wall of the through groove 121 is slidably connected to the surface of the movable plate 221. The through groove 121 can provide the movable plate 221 with room to move, so that the movable plate 221 can move synchronously with the unlocking component 300, and can also guide the movable plate 221 to avoid shaking or deviation.

[0034] In order to shield the through groove 121, a baffle 223 is fixedly connected to the surface of the movable plate 221, and the size of the baffle 223 is larger than the size of the through groove 121. A first rubber gasket is fixedly connected to the bottom of the baffle 223, and the first rubber gasket contacts the top of the handle 120. Through the cooperation of the baffle 223 and the first rubber gasket, external dust and other impurities or water droplets can be effectively prevented from entering the inner cavity of the handle 120 through the through groove 121.

[0035] To facilitate operation of the latch 220, the pressing component 310 includes a button 311 that is movably disposed through the surface of the handle 120. A pressure plate 312 is fixedly connected to one side of the button 311. The pressure plate 312 is located in the inner cavity of the handle 120. Two symmetrically arranged springs 313 are fixedly connected to the side of the pressure plate 312 facing the linkage 320. A support plate 314 is fixedly connected to the other end of the springs 313. The support plate 314 is fixedly connected to the inner cavity of the handle 120. The linkage 320 is disposed between the pressure plate 312 and the movable plate 221, allowing for... The pressing part 310 allows the user to easily operate the latch 220 while holding the handle 120, making the adjustment operation of the handle 120 more convenient. The handle 120 has a through hole for the button 311 to pass through. A second rubber gasket is fixedly connected to the inner wall of the through hole. The inner wall of the second rubber gasket is in contact with the surface of the button 311. The second rubber gasket can seal the gap between the button 311 and the through hole, further preventing external dust and other impurities or water droplets from entering the inner cavity of the handle 120 through the through hole.

[0036] To improve the ease of adjustment of the handle 120, the linkage 320 includes a gear 321 rotatably connected to the inner cavity of the handle 120 via a bearing. The top and bottom of the gear 321 are respectively meshed with a toothed plate 322. The upper toothed plate 322 is fixedly connected to the bottom of the movable plate 221, and one side of the lower toothed plate 322 extends movably through to one side of the support plate 314 and is fixedly connected to the pressure plate 312. The side of the toothed plate 322 away from the gear 321 is slidably connected to the inner wall of the handle 120. The linkage 320 can change the direction of force. When the pressing member 310 is pressed, the linkage 320 causes the pin 220 to move away from the limiting member 210 to achieve the unlocking function, further improving the ease of adjustment of the handle 120.

[0037] In summary, this utility model embodiment allows for adjustment of the angle and height of the handle 120 via the unlocking component 300. This not only provides a personalized user experience for people of different heights by using the handle 120 at different angles and heights, but also makes the adjustment process simple and convenient, thus helping to improve the overall door opening and closing efficiency.
