Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to an ultra-thin embedded three-dimensional adjustable magnetic damping hinge. Background Art

[0002] The hinge is a commonly used opening and closing device for the door frame. In existing household appliances, in order to prevent injuries to people when the door frame is opened quickly, or to prevent the hand from being pinched or violently hit when the door frame is closed quickly, which may cause the sealing structure to fail, a damping hinge is generally used. The damping hinge can gradually slow down the opening speed of the door frame until the door frame is opened, which is not easy to injure people. At the same time, it can also slow down the closing speed when closing the door frame so that the door frame closes slowly, which is not easy to pinch hands and avoid violent impact. However, due to the damping, the resistance will be greater when closing the door, so that the force required to close the door is also heavier. Therefore, there are now damping hinges with magnetic force on the market. By providing mutually attractive magnetic parts on the hinge body and the movable seat, the magnetic parts will provide mutually attractive magnetic force to assist in closing the door when closing the door, thereby reducing the force required to close the door.

[0003] However, one end of the hinge body of the current magnetic damping hinge is generally directly installed on the side of the door frame, and the thickness of the hinge body is relatively thick as a whole, so the overall appearance is greatly affected after installation.

[0004] The technical problem to be solved by the present application is: to design an ultra-thin embedded three-dimensional adjustable magnetic damping hinge that can reduce the thickness of the hinge and can be hidden for installation to enhance the aesthetics after installation.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1: Please refer to Figure 1-8The utility model provides a technical solution: an ultra-thin embedded three-dimensional adjustable magnetic damping hinge, comprising a mounting shell 4, a buffer seat 1 and a hinge body 2 rotatably connected to the buffer seat 1, the hinge body 2 is provided with an adjusting base 3 rotatably connected thereto, one end of the hinge body 2 cantilever is rotatably connected to the adjusting base 3, the mounting shell 4 is mainly used to limit and install one end of the hinge body 2 and the adjusting base 3, the hinge body 2 comprises a first cantilever 20 and a second cantilever 21, the longitudinal cross-section between the first cantilever 20 and the second cantilever 21 is arranged in a Z shape, one end of the first cantilever 20 is rotatably connected to the adjusting base 3, the adjusting base 3 comprises a bottom plate 30 and an adjusting plate 31 limitedly matched with the bottom plate 30, a limiting groove 301 for reducing the thickness of the entire adjusting base 3 is provided on the bottom plate 30, a connecting portion 310 is provided on the adjusting plate 31, and the connecting portion 310 is provided with a connecting hole 311, when the bottom plate 30 and the adjusting plate 31 are limitedly matched and installed, the hinge body 2 is moved by the first cantilever 20 and the second cantilever 21. When the bottom plate 30 is in the locked state, the lower end of the connecting portion 310 is placed in the locking groove 301, so that the position of the connecting hole 311 on the connecting portion 310 can be sunk, thereby reducing the height of the entire connecting portion 310 compared to the original height, thereby reducing the thickness of the entire adjusting base 3. Therefore, when the first cantilever 20 of the hinge body 2 is rotatably connected to the adjusting base 3, the first cantilever 20 of the hinge body 2 and the adjusting base 3 are placed in the mounting shell 4 for limited mounting, thereby further reducing the thickness of the entire mounting shell 4, and then the mounting shell 4 is embedded in the door frame for hidden mounting, thereby improving the overall appearance after installation.

[0032] A pin hole 200 is provided in the first cantilever 20, and a rotatable pin shaft 201 is provided in the pin hole 200. The two ends of the pin shaft 201 are respectively passed through the connecting holes 311 on the connecting portion 310 so that the adjusting plate 31 and the first cantilever 20 can be rotatably connected. Limiting grooves 302 are also provided on both sides of the bottom plate 30, and side plates 312 are provided on both sides of the adjusting plate 31. The connecting portion 310 is located at one end of the side plate 312. The limiting cooperation between the side plate 312 and the limiting groove 302 can realize the limiting cooperation between the adjusting plate 31 and the bottom plate 30.

[0033] The first cantilever 20 is also provided with a first adjustment hole 202, a second adjustment hole 203 and a third adjustment hole 204, both of which are U-shaped holes. A first eccentric nail 205 and a second eccentric nail 206 are respectively provided in the first adjustment hole 202 and the second adjustment hole 203, and the length directions of the first adjustment hole 202 and the second adjustment hole 203 are perpendicular to each other. An adjustment screw 207 is also provided in the third adjustment hole 204. A first limiting hole 303 is provided on the bottom plate 30, and a second limiting hole 313 and a third limiting hole 314 are provided on the adjustment plate 31. The first eccentric nail 205 and the second eccentric nail 206 are respectively provided in the first adjustment hole 202 and the second adjustment hole 203. The eccentric nail 206 respectively passes through the first limiting hole 303 and the second limiting hole 313, so when the first cantilever 20 of the hinge body 2 is rotatably connected with the adjustment base 3 and all are placed in the mounting shell 4 for limiting installation, an adjustment port 45 corresponding to the first cantilever 20 is also provided on the mounting shell 4, and an adjustment square port 7 is also provided on the door frame. After the mounting shell 4 is embedded and installed in the door frame, the adjustment square port 7 corresponds to the adjustment port 45, so as to facilitate adjustment. When adjustment is required, the first eccentric nail 205, the second eccentric nail 206 and the adjusting screw 206 can be adjusted respectively by using a screwdriver to pass through the adjustment square port 7 on the door frame and then through the adjustment port 45. 07, and because the first adjustment hole 202 and the second adjustment hole 203 are both U-shaped holes, and the length directions therebetween are perpendicular to each other, which is equivalent to the X and Y directions. Therefore, when the first eccentric nail 205 and the second eccentric nail 206 are adjusted respectively, the hinge body 2 can be moved and adjusted in the installation shell 4 in the X and Y directions, so that the door panel 5 and the door frame are installed and aligned to adapt to the switch, and by using a screwdriver to adjust the adjusting screw 207, the locking degree of the adjusting screw 207 on the first cantilever 20 can be controlled. Because the first cantilever 20 is rotatably connected to the adjustment base 3, by controlling the adjusting screw 207 The locking degree of the first cantilever 20 can drive the first cantilever 20 to be vertically lifted and lowered relative to the X and Y planes, and then the first cantilever 20 can be driven to be appropriately adjusted in the Z-axis direction, thereby adjusting the position of the first cantilever 20 on the Z-axis, so that the hinge body 2 can be driven to shift in the Z-axis direction by adjusting the adjusting screw 207 after installation, so that the hinge body 2 can be hidden from the front of the door panel 5 after the door panel 5 is closed, which is equivalent to making the hinge body 2 flush with the side of the door frame after installation, so that the door panel 5 will not be exposed when viewed from the front after closing, thereby improving the appearance.

[0034] A limiting mechanism 32 for limiting and fixing the hinge body 2 and the mounting shell 4 is also provided on the adjustment base 3. By providing the limiting mechanism 32, the hinge body 2 can be fixedly installed in the mounting shell 4 and locked, and the limiting mechanism 32 can also be adjusted to make the hinge body 2 fall off and be disassembled from the mounting shell 4. The limiting mechanism 32 includes a limiting spring piece 320 and a limiting nail 321 that cooperates with the limiting spring piece 320. A limiting groove 322 is provided at the waist position of the limiting nail 321. The horizontal cross-section of the waist of the limiting nail 321 is U-shaped, that is, the two sides of the waist of the limiting nail 321 are vertical planes, and the front and rear ends of the waist are vertical arc surfaces. The two ends of the limiting spring piece 320 are provided with a clamping groove 323. By making the clamping groove 323 and the limiting groove 322 2 are mutually engaged and locked so that the limiting nail 321 is locked and installed on the limiting spring piece 320, the bottom plate 30 is respectively provided with two first through holes 304 corresponding to the limiting nail 321, and the bottom of the mounting shell 4 is respectively provided with two second through holes 400 corresponding to the two first through holes 304, the lower end of the limiting nail 321 passes through the first through hole 304 and the second through hole 400 respectively, and the lower end surface of the limiting nail 321 is a beveled surface, and a rivet hole 305 is also provided on the bottom plate 30, and the limiting spring piece 320 is installed on the bottom plate 30 by locking between the rivet 306 and the rivet hole 305. When it is necessary to place the hinge body 2 together with the adjustment base 3 in the mounting shell 4, it is necessary to use a screwdriver to rotate the limiting nail 321 so that the lower end of the limiting nail 321 The beveled surface at the end is just opposite to the entrance of the mounting shell 4, and then the hinge body 2 together with the adjusting base 3 is pushed into the mounting shell 4. When the beveled surface at the lower end of the limiting pin 321 contacts the bottom of the entrance of the mounting shell 4, due to the pushing, the beveled surface at the lower end of the limiting pin 321 will bounce up due to the pushing force, thereby driving the limiting pin 321 to rise, so that the hinge body 2 and the adjusting base 3 can be smoothly pushed into the mounting shell 4. At this time, the limiting pin 321 is subjected to the downward elastic force of the limiting spring piece 320, and the lower part of the limiting pin 321 will always abut against the bottom of the mounting shell 4. As the hinge body 2 together with the adjusting base 3 is continuously pushed into the mounting shell 4, when the limiting pin 321 passes through the second through hole 400, When the hinge body 2 is pulled out, the back surface of the oblique cut surface of the lower end of the limiting nail 321 will conflict with the side wall of the second through hole 400, which is equivalent to that the limiting nail 321 cannot be subjected to the upward force to cause the limiting spring piece 320 to deform upward, that is, the limiting nail 321 cannot move upward and disengage from the second through hole 400, so that the hinge body 2 can be connected to the adjusting base 3 and remain fixed in the installation shell 4. When the hinge body 2 and the adjusting base 3 need to be taken out,At this time, you only need to use a screwdriver to twist the limit pin 321 180 degrees to reverse the direction of the lower beveled surface of the limit pin 321. In this way, when the hinge body 2 is pulled outward, the lower beveled surface of the limit pin 321 contacts the side wall of the second through hole 400, which will generate an upward force to cause the limit spring 320 to deform upward and drive the limit pin 321 to rise from the second through hole 400, so that the hinge body 2 and the adjustment base 3 can be smoothly removed from the mounting shell 4. By setting the two sides of the waist of the limit pin 321 as vertical planes, and the front and rear ends of the waist as vertical arc surfaces, when the limit pin 321 is rotated, a 180-degree deflection can be smoothly achieved, which is convenient for adjusting the rotation angle.

[0035] A first magnetic component 210 is also provided on the second cantilever 21 and is installed therewith to limit the position. A second magnetic component 100 is provided on the buffer seat 1. The first magnetic component 210 and the second magnetic component 100 are arranged corresponding to each other, so that when closing the door, the first magnetic component 210 and the second magnetic component 100 can generate mutual attraction to assist in closing the door, thereby reducing the closing force.

[0036] A mounting hole 101 is also provided in the buffer seat 1, and the second magnetic component 100 is located in the mounting hole 101, and a limiting edge 102 is also provided on the upper side of the mounting hole 101. By providing the limiting edge 102 on the upper side of the mounting hole 101, it is possible to prevent the second magnetic component 100 from being sucked out and falling off due to the suction force between the first magnetic component 210 and the second magnetic component 100 when the door is opened. A buffer 103 is also provided in the buffer seat 1. By providing the buffer 103, it is possible to prevent the suction force between the first magnetic component 210 and the second magnetic component 100 when closing the door from causing the door to close too quickly, thereby preventing the door panel 5 from being damaged or bumped.

[0037] Connecting plates 104 are also provided on both sides of the buffer seat 1, and a socket 105 is provided on the connecting plate 104. A spring pin 22 for limiting installation is provided on the second cantilever 21 of the hinge body 2. When the hinge needs to be installed, the buffer seat 1 is first installed in the door panel 5, and a hinge hole 51 is provided on the door panel 5 corresponding to the socket 105. Then, the first cantilever 20 of the hinge body 2 is installed together with the adjusting base 3 in the mounting shell 4, and then the mounting shell 4 is embedded in the door frame side plate 312 for fixed installation. Finally, the spring pin 22 is pressed to align it with the socket 105, and then the pressure on the spring pin 22 is released, so that the spring pin 22 pops out from the socket 105 and is rotatably connected with the hinge hole 51 on the door panel 5, so that the rotational connection between the second cantilever 21 and the door panel 5 can be realized, thereby realizing the installation of the entire hinge.

[0038] An installation cavity 40 is also provided in the installation shell 4, and the first cantilever 20 is limitedly installed in the installation cavity 40 together with the adjustment base 3, and the installation shell 4 includes an upper shell 401 and a lower shell 402, the upper shell 401 is provided with an upper hook block 403 protruding downward, and the lower shell 402 is provided with a lower hook block 404 protruding upward. When it is necessary to realize mutual locking installation between the upper shell 401 and the lower shell 402, the upper shell 401 and the lower shell 402 are made relative to each other, and then the upper hook block 403 and the lower hook block 404 are mutually misaligned, and then the upper shell 401 is pushed toward the lower hook block 404, so that the upper hook block 403 and the lower hook block 404 are mutually locked and cooperated, so that the upper shell 401 and the lower shell 402 are realized. The upper shell 401 is also provided with a limiting protrusion 405, and the lower shell 402 is provided with a recessed portion 406, and an anti-dropping block is provided in the recessed portion 406 When the upper shell 401 is pushed, the limiting protrusion 405 will slide along the inclined surface of the anti-falling block 407 and fall into the positioning groove 408 to cooperate with it. Because the other side of the anti-falling block 407 is a straight surface, the limiting protrusion 405 cannot fall out of the positioning groove 408 again by pushing the upper shell 401 in the positioning groove 408, and because the upper hook block 403 and the lower hook block 404 are hooked and locked with each other at this time, when the limiting protrusion 405 cannot slide out of the positioning groove 408 by translation, the upper hook block 403 and the lower hook block 404 cannot be separated, thereby realizing the locking and fixation between the upper shell 401 and the lower shell 402.

[0039] In order to achieve fixed installation of the installation shell 4 in the door frame side plate 312, ears 41 are further provided at both ends of the installation shell 4, and a limit locking mechanism is provided on the ears. The limit locking mechanism includes a limit block 46 located on the back side of the hanger 41, a locking block 43 that cooperates with the limit block 46, and a locking screw 44 for limiting and locking the limit block 46 and the locking block 43. The opposing surfaces of the limit block 46 and the locking block 43 are both inclined surfaces, and a through hole 42 is provided between the limit block 46 and the hanger 41, and the locking block 43 is provided with a locking hole corresponding to the through hole 42. When installing the installation shell 4, first open an installation groove on the door frame, and then use the locking screw 44 to pass through the through hole 42 and connect with the locking hole on the locking block 43, and then place the entire installation shell 4 in the installation groove, and then continue to lock it. The screw 44 rotates. Since the opposing surfaces of the limit block 46 and the locking block 43 are both inclined surfaces, when the locking screw 44 continues to be rotated and locked, the locking screw 44 will drive the locking block 43 to move upward along the inclined surface of the limit block 46, so that the back side of the ear 41 and the locking block 43 fit each other. Since the locking block 43 moves from the lower end of the inclined surface of the limit block 46 to the upper end of the inclined surface of the limit block 46, the side surface of the locking block 43 squeezes the side wall of the mounting groove in the door frame, thereby fixing the entire mounting shell 4 in the mounting groove, and a screw tenon 430 is provided on the side surface of the locking block 43. When the door frame side panel 312 is made of wood, the screw tenon 430 in the locking block 43 will be inserted into the wood to further ensure the installation stability of the mounting shell 4.
