Technical Field
[0001] The utility model relates to the field of sky and earth hinges, in particular to a sky and earth hinge with a simplified up and down adjustment structure. Background Art
[0002] At present, the top and bottom hinges are used to hinge the cabinet door to the cabinet body. The top and bottom hinges on the market usually have a three-dimensional adjustment function, that is, they can adjust the cabinet door front and back, left and right, and up and down, which is conducive to making the cabinet door straight when it is in a closed state. The up and down adjustment structure of the top and bottom hinges in the prior art usually uses an eccentric shaft. The eccentric shaft is rotated so that the radial protrusion of the eccentric shaft lifts up the movable shell of the top and bottom hinge. However, when the weight of the cabinet door is large, the friction force on the eccentric shaft is not enough to offset the torque of the gravity of the cabinet door on the eccentric shaft, which will cause the eccentric shaft to rotate and make the up and down adjustment ineffective. For this purpose, the Chinese utility model patent with publication number CN216130731U discloses "a double-spring heavy-duty top and bottom hinge": the first adjusting bevel block is slidably connected to the lifting block, the outer bevel of the first adjusting bevel block is abutted against the inner bevel of the lifting block, and the upper and lower adjusting screws drive the first adjusting bevel block to move along the axial direction of the upper and lower adjusting screws. Since the movable shell restricts the movement of the lifting block in the up and down directions, the first adjusting bevel block can drive the hinge block to be lifted and lowered relative to the movable shell; although the threaded connection structure between the upper and lower adjusting screws and the first adjusting bevel block has a self-locking effect, the bevel structure is difficult to process, resulting in excessively high costs, especially it is more difficult to process the above-mentioned inner bevel inside the lifting block. If the first adjusting bevel block and the lifting block are made by casting, it will also lead to difficulties in mold making and high casting process costs, so it is necessary to improve the top and bottom hinges of the prior art.

Implementation
[0019] The utility model is further described below in conjunction with the accompanying drawings.
[0020] The utility model has a simplified upper and lower adjustment structure of the top and bottom hinge, such as Figures 1 to 3 As shown, it includes a fixed component 1 and a movable component 2, and the movable component 2 includes a movable housing 201 for installation on the cabinet door. Figure 4 As shown, the movable housing 201 is formed with an articulated seat accommodating cavity 2011, and an articulated seat 204 is relatively slidably arranged in the articulated seat accommodating cavity 2011. The articulated seat 204 specifically includes two upper and lower clamping plates, and the articulated seat 204 also includes a cushion block arranged between the upper and lower clamping plates. The above-mentioned clamping plates and cushion blocks are connected by two riveted pins, such as Figure 2 and Figure 3 As shown, the movable housing 201 is fixedly connected with a guide column 208, and the guide column 208 is slidably arranged through the hinge seat 204, so that the hinge seat 204 can move up and down relative to the movable housing 201, and the fixed component 1 is connected to the hinge seat 204 through the first swing arm 3 and the second swing arm 4. More specifically, one end of the first swing arm 3 is hinged to the fixed component 1, and the other end of the first swing arm 3 is hinged to the hinge seat 204 through the corresponding riveted pin shaft mentioned above, and one end of the second swing arm 4 is hinged to the fixed component 1, and the other end of the second swing arm 4 is hinged to the hinge seat 204 through the corresponding riveted pin shaft mentioned above, and the other end of the first swing arm 3 and the other end of the second swing arm 4 are both arranged between the upper and lower two above-mentioned clamping plates.
[0021] like Figure 4 As shown, the movable housing 201 is formed with a lifting member accommodating cavity 2012. Figure 2 and Figure 3 As shown, a lifting member 205 is provided in the lifting member accommodating cavity 2012 to slide up and down relatively. Figure 5 As shown, the lifting member 205 includes a connecting plate portion 2051, and the two ends of the connecting plate portion 2051 are bent upward to form a side plate portion 2052, and an oblique long hole 2053 is formed on the side plate portion 2052. One end of the oblique long hole 2053 is higher than the other end corresponding to the oblique long hole 2053. In other words, the lifting member 205 is a sheet metal structure. Figure 3 In the visual direction, the side plate portion 2052 is respectively against the left and right inner walls of the lifting member accommodating chamber 2012, and the front and rear ends of the side plate portion 2052 are also respectively against the inner walls of the lifting member accommodating chamber 2012, so that the lifting member accommodating chamber 2012 restricts the lifting member 205 to move up and down in a relatively straight line. Figure 4 As shown, the lower end of the lifting member accommodating chamber 2012 is connected to the hinge seat accommodating chamber 2011. Figure 3 As shown, the connecting plate portion 2051 is relatively fixed to the upper side of the hinge seat 204, and a slider 206 is adapted between the two side plate portions 2052. Figure 6 As shown, a screw hole 2061 and a pin connection hole 2062 are formed on the slider 206, and the screw hole 2061 and the pin connection hole 2062 are arranged in an up-down staggered manner, as shown in FIG. Figure 2 and Figure 3 As shown, the movable housing 201 is rotatably connected with the upper and lower adjusting screws 202. Specifically, as shown in FIG. Figure 7 As shown, one end of the upper and lower adjusting screw 202 is formed with a nail head 2021, and the other end of the upper and lower adjusting screw 202 corresponding to the riveting portion 2022 is formed. Figure 4 As shown, the movable housing 201 is formed with an adjusting screw installation hole 2013, and the upper and lower adjusting screws 202 pass through the adjusting screw installation hole 2013, so that the movable housing 201 is clamped between the nail head 2021 and the riveting part 2022, so that the upper and lower adjusting screws 202 are axially positioned relative to the movable housing 201. Figure 3 As shown, the upper and lower adjustment screws 202 are adapted to connect the screw holes 2061, so that the slider 206 can only move linearly but not rotate through the guiding effect of the two side plates 2052. The driving pin 203 is adapted to be arranged in the pin connection hole 2062. The driving pin 203 is relatively slidably arranged in the oblique long hole 2053. In other words, the driving pin 203 passes through the pin connection hole 2062 so that the left and right ends of the driving pin 203 protrude outside the slider 206, so that the left and right ends of the driving pin 203 can be respectively inserted into the corresponding oblique long hole 2053. Figure 3 As shown, the axis of the upper and lower adjusting screws 202 and the axis of the driving pin 203 are both arranged horizontally, and the axis of the upper and lower adjusting screws 202 is perpendicular to the axis of the driving pin 203. As can be seen from the above, the upper and lower adjusting screws 202, the driving pin 203, the hinge seat 204, the lifting member 205 and the slider 206 participate in forming the upper and lower adjusting structure of the utility model.
[0022] When the height position of the cabinet door needs to be adjusted, the up-down adjustment screw 202 is rotated with a screwdriver, and the up-down adjustment screw 202 drives the slider 206 to move horizontally, and the driving pin 203 moves horizontally in the oblique long hole 2053, so that the driving pin 203 squeezes the oblique long hole 2053, forcing the lifting member 205 to move up and down relative to the movable housing 201. Since the lifting member 205 is fixedly connected to the hinge seat 204, it is actually the movable housing 201 that moves up and down, thereby adjusting the cabinet door up and down. The gravity of the cabinet door acts on the movable housing 201 and is transmitted to the slider 206 through the up-down adjustment screw 202. The oblique long hole 2053 supports the driving pin 203 and makes the up-down adjustment screw 202 and the slider 206 generate a large relative axial force, so that the up-down adjustment screw 202 and the slider 206 are self-locked, and the up-down adjustment screw 202 is prevented from loosening and rotating, so that the up-down adjustment effect of the cabinet door can be maintained. The utility model provides a simple structure of the lifting member 205, so that the lifting member 205 can be easily manufactured by sheet metal processing, which is conducive to reducing costs, especially in the case of small batch production. By providing an assembly structure of the driving pin 203 and the slider 206, it is avoided to manufacture a slider 206 with a complex shape, which is conducive to making the slider 206 easy to manufacture and reducing costs.
[0023] Furthermore, if Figure 5 As shown, the connecting plate portion 2051 is formed with a mounting screw hole 2054. Figure 3 As shown, the mounting screw hole 2054 is installed with a connecting screw 207, and the connecting screw 207 is arranged to pass through the hinge seat 204 upward, and the hinge seat 204 and the lifting member 205 are relatively fixed by the connecting screw 207, as shown in FIG. Figure 3 and Figure 4 As shown, the lower end of the movable shell 201 is formed with an avoidance hole 2014 for avoiding the connecting screw 207, so that the connecting screw 207 can be passed upward through the avoidance hole 2014 and then through the hinge seat 204, and then the connecting screw 207 is rotated with a screwdriver to screw the connecting screw 207 and fix it to the connecting plate part 2051. When the movable shell 201 is moved up and down for adjustment, the head of the connecting screw 207 can move in the avoidance hole 2014, which is conducive to making the structure of the movable component 2 compact and avoiding the need to open a larger groove on the inner side of the cabinet door for accommodating the movable shell 201.
[0024] Furthermore, if Figure 3 and Figure 4As shown, the lifting member accommodating chamber 2012 is arranged to penetrate the movable housing 201 upward, so during the assembly process, the slider 206 can be first placed in the lifting member 205, and then the driving pin 203 can be inserted into the oblique long hole 2053 on one side, and the driving pin 203 then passes through the pin connecting hole 2062 of the slider 206, and then the lifting member 205 is inserted into the lifting member accommodating chamber 2012 through the upper end opening of the lifting member accommodating chamber 2012. After the hinge seat 204 is assembled with the first swing arm 3 and the second swing arm 4, the hinge seat 204 is inserted into the hinge seat accommodating chamber 2011, and then the connecting screw 207 is passed upward through the avoidance hole 2014 to fix the lifting member 205 and the hinge seat 204. In other words, by setting the lifting member accommodating chamber 2012 to penetrate the movable housing 201 upward, the lifting member 205 can be easily installed.
[0025] Furthermore, if Figure 2 As shown, the driving pin 203 is configured as a cylindrical pin, which facilitates the manufacture of the pin connecting hole 2062. Since the cylindrical surface of the driving pin 203 is in line contact with the inner wall of the oblique long hole 2053, the friction force is small, and the cylindrical surface of the driving pin 203 does not produce a sharp structure, which also facilitates the driving pin 203 to slide easily in the oblique long hole 2053.
[0026] Furthermore, if Figure 3 As shown, the two end surfaces of the driving pin 203 are respectively abutted against the inner wall of the lifting member accommodating cavity 2012, so that the driving pin 203 is axially restricted in the lifting member accommodating cavity 2012, preventing the driving pin 203 from axially shifting and causing it to leave the working position, thereby avoiding the need to set the driving pin 203 and the slider 206 as an interference fit, which is conducive to easy installation of the driving pin 203.
