Description

Technical Field

[0001] This utility model relates to the field of hinges, specifically to a flexible adjustable hinge. Background Technology

[0002] Currently, top and bottom hinges refer to hinges suitable for installation at the lower and upper ends of aluminum frame cabinet doors. A top and bottom hinge includes a hinge base assembly, a movable assembly, a first swing arm, and a second swing arm. The hinge base assembly has a middle plate assembly, which is connected to the movable assembly via the first and second swing arms. Since the movable assembly is installed on the cabinet door, the first and second swing arms exert significant downward pressure on the middle plate assembly. The fixed housing of the top and bottom hinge is installed on the cabinet body, thus supporting the aforementioned downward pressure. This creates a relatively large gap between the portion of the middle plate assembly connecting the first and second swing arms and the inner wall of the fixed housing. The high pressure results in significant friction between the two components. Existing hinges with front and rear adjustment pins have eccentric left and right adjustment pins positioned between them and the main stress-bearing area of ​​the fixed housing. This creates a large distance between the front and rear adjustment pins and the main stress-bearing area of ​​the fixed housing. For example, in Chinese Utility Model Patent Publication No. CN217151633U, "A Split-Type Adjustable Hinge," when the front and rear adjustment pins apply a forward and backward thrust to the assembly of the middle plate assembly and the front and rear adjustment seats, gaps inevitably exist between the parts, and each part may also undergo some elastic deformation. That is to say, because the middle plate assembly... There is significant friction between the connection points of the first and second swing arms and the inner wall of the fixed housing, hindering the forward and backward movement of the connection points of the middle plate assembly. Furthermore, due to the large distance between the front and rear adjusting pins and the main stress area of ​​the fixed housing, the thrust exerted by the front and rear adjusting pins on the middle plate assembly is along the front-back direction. Therefore, the thrust exerted by the front and rear adjusting pins on the front and rear adjusting seats easily causes elastic bending deformation and horizontal rotation of the assembly of the middle plate assembly and the front and rear adjusting seats. Consequently, the displacement of the front and rear adjusting pins in the front-back direction is consumed in the gaps between the parts and the elastic bending of the parts. In terms of deformation and swaying, it also leads to a larger bending moment on the front and rear adjusting pins, causing greater frictional resistance to the forward and backward movement of the front and rear adjusting pins; the front and rear adjusting pins indirectly drive the middle plate assembly to move forward and backward through the front and rear adjusting seats, so the connection gap between the front and rear adjusting seats and the middle plate assembly will affect the actual movement range of the middle plate assembly driven by the front and rear adjusting pins, making it difficult for the displacement of the front and rear adjusting pins to be transmitted to the first and second swing arms, making the front and rear adjustment of the cabinet door inflexible and significantly reducing the actual front and rear adjustment stroke. Therefore, the structural layout of the existing top and bottom hinge has unreasonable aspects and needs to be improved. Summary of the Invention

Detailed Implementation

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] The flexible adjustable top and bottom hinge of this utility model, such as Figure 1 and Figure 2 As shown, the system includes a hinged base assembly 1, a movable component 2, a first swing arm 3, and a second swing arm 4. The hinged base assembly 1 includes a load-bearing frame 130. The front right part of the load-bearing frame 130 is connected to the movable component 2 via the first swing arm 3 and the second swing arm 4. The hinged base assembly 1 is used for mounting on the cabinet body, and the movable component 2 is used for mounting on the cabinet door. One end of the first swing arm 3 is hinged to the load-bearing frame 130, and the corresponding other end of the first swing arm 3 is hinged to the movable component 2. One end of the second swing arm 4 is hinged to the load-bearing frame 130, and the corresponding other end of the second swing arm 4 is hinged to the movable component 2. Figure 2 As shown, the hinge assembly 1 includes a fixed housing 10, a left-right adjusting seat 15, a front-back adjusting pin 17, and a left-right adjusting pin 18, as... Figure 3 As shown, the left and right adjustment seat 15 is slidably connected to the fixed outer shell 10 in the left and right directions, and the left and right adjustment seat 15 is slidably connected to the load-bearing frame 130 in the front and back directions, as shown. Figure 4 As shown, the left and right adjustment seat 15 has front and rear guide elongated holes 1502 formed on it, such as Figure 3 As shown, the load-bearing frame 130 is riveted with two sliding pins 1302. The sliding pins 1302 are adapted to pass through the corresponding front and rear guide elongated holes 1502, thus guiding the load-bearing frame 130 to move back and forth relative to the left and right adjusting seat 15. Figures 1 to 3 As shown, the load-bearing frame 130 is housed within the fixed housing 10, which is assembled from an upper cover 11 and a lower cover 12. Figure 2 As shown, the front part of the front and rear adjusting pins 17 is screwed into the front part of the left and right adjusting seats 15, specifically, as... Figure 4 As shown, the left and right adjustment seat 15 has front and rear adjustment screw holes 151, as... Figure 7 As shown, the front part of the front and rear adjusting pins 17 has external threads, so the front part of the front and rear adjusting pins 17 is screwed into the front and rear adjusting screw holes 151. Figure 3 As shown, the rear of the front and rear adjusting pins 17 is connected to the load-bearing frame 130, and the left and right adjusting pins 18 are rotatably connected to the front of the fixed housing 10. The left and right adjusting pins 18 drive the left and right adjusting seats 15 to move left and right for adjustment. For example, the front end and the rear end of the left and right adjusting pins 18 can be eccentrically set. Therefore, the structural principle of the left and right adjusting pins 18 driving the left and right adjusting seats 15 to move left and right can be referred to "A Split-Type Adjustable Top and Bottom Hinge" in Chinese Utility Model Patent Publication No. CN217151633U. Figure 5 As shown, a supporting inner bottom 1001 is formed inside the right front part of the fixed outer casing 10, as... Figure 1 and Figure 3As shown, the front right part of the load-bearing frame 130 rests against the inner bottom of the support 1001. That is to say, the inner bottom of the support 1001 is used to support the weight of the cabinet door. The inner bottom of the support 1001 is the main stress area. The front and rear adjustment pins 17 are located on the left side of the inner bottom of the support 1001, and the left and right adjustment pins 18 are located on the left side of the front and rear adjustment pins 17. This allows the front and rear adjustment pins 17 to be positioned close to the inner bottom of the support 1001. The distance from the point of force application of the front and rear adjustment pins 17 on the load-bearing frame 130 to the inner bottom of the support 1001 is... The shorter distance reduces the elastic deformation of the load-bearing frame 130 caused by the thrust of the front and rear adjusting pins 17, and also reduces the swing amplitude of the load-bearing frame 130. Furthermore, since the front and rear adjusting pins 17 are directly connected to the load-bearing frame 130, the forward and backward displacement of the front and rear adjusting pins 17 can directly drive the right front part of the load-bearing frame 130 to move forward and backward. This allows the front and rear adjusting pins 17 to easily drive the first swing arm 3 and the second swing arm 4 to move forward and backward effectively, thus facilitating effective and flexible adjustment of the cabinet door. Figure 1 As shown, for ease of operation, the left and right adjustment pins 18 and the front and rear adjustment pins 17 are all positioned at the front. This is because the left and right adjustment pins 18 are meant to exert a thrust on the load-bearing frame 130 in the left and right direction. Since the inner bottom 1001 of the support is located at the front right side of the fixed outer shell 10, the thrust exerted by the left and right adjustment pins 18 on the load-bearing frame 130 has a relatively short lever arm relative to the front right side of the fixed outer shell 10. This makes it less likely for the load-bearing frame 130 to undergo elastic bending deformation and swaying. In other words, the arrangement of the left and right adjustment pins 18 in the left and right direction has a relatively small impact on the left and right adjustment of the load-bearing frame 130.

[0021] Furthermore, such as Figure 2 and Figure 3 As shown, the hinge assembly 1 includes a drive block 16, which is slidably connected to the fixed housing 10. Specifically, a groove extending in the front-rear direction is formed on the inner wall of the fixed housing 10, and rectangular protrusions are formed on the upper and lower surfaces of the drive block 16. The rectangular protrusions are slidably disposed in the corresponding grooves, thereby the fixed housing 10 linearly guides the drive block 16 to move back and forth. Figure 2 As shown, the rear of the left and right adjusting pin 18 is screwed to the drive block 16, as... Figure 3 As shown, the axis of the left and right adjusting pins 18 extends along the front-to-back direction, as... Figure 2 and Figure 3 As shown, the drive block 16 is provided with a drive pin 161, as follows: Figure 4 As shown, an adjustment oblique hole 1501 is formed on the left side of the left adjustment seat 15. That is to say, the adjustment oblique hole 1501 forms a 45-degree angle with the sliding direction of the drive block 16. The drive pin 161 is slidably disposed in the adjustment oblique hole 1501. The cylindrical drive pin 161 is adapted to fit into the circular mounting hole on the drive block 16. Figure 3As shown, the left and right adjusting screws 18 can be made of Phillips head countersunk screws, such as... Figure 5 As shown, an inner annular groove 101 is formed in the front part of the fixed housing 10, such as Figure 3 As shown, specifically, the head of the left and right adjusting pins 18 is fitted into the inner ring groove 101, allowing the left and right adjusting pins 18 to rotate. However, the left and right adjusting pins 18 are axially positioned by the inner ring groove 101. Therefore, when the left and right adjusting pins 18 are rotated, they can drive the drive block 16 to move back and forth, causing the drive pin 161 to push against the inner wall of the adjusting oblique hole 1501. Since the left and right adjusting seat 15 is slidably connected to the fixed housing 10, it can only move left and right for adjustment. By setting the above-mentioned combination structure of the drive pin 161 and the adjusting oblique hole 1501, during the adjustment process, it is beneficial to make the force required by the user to rotate the left and right adjusting pins 18 more even, and the adjustment movement is also more stable (compared to the eccentric pin structure of the prior art).

[0022] Furthermore, such as Figure 2 and Figure 6 As shown, the load-bearing frame 130 includes an upper plate 13 and a lower plate 14, as follows: Figure 2 and Figure 3 As shown, the left-right adjusting seat 15 (in the vertical direction) is adapted to be positioned between the upper plate 13 and the lower plate 14, as follows: Figure 6 As shown, the front of the lower plate 14 has an upwardly bent fork plate 1401, and a connecting groove 1402 is formed on the fork plate 1401. The front of the upper plate 13 has a closed protrusion 1301, which is adapted to fit inside the upper end of the connecting groove 1402. Figure 7 As shown, a ring groove 171 is formed at the rear of the front and rear adjusting pins 17, as... Figure 3 As shown, the ring groove 171 engages with the edge of the connecting groove 1402. Therefore, when the front and rear adjusting pins 17 are rotated to move them back and forth relative to the left and right adjusting seats 15, the ring groove 171 pushes the edge of the connecting groove 1402, thereby adjusting the position of the load-bearing frame 130. By setting the ring groove 171 to engage with the edge of the connecting groove 1402, and the front part of the front and rear adjusting pins 17 being screwed into the left and right adjusting seats 15, the gap between the ring groove 171 and the connecting groove 1402 is reduced. This reduces the amplitude of the slight horizontal swing of the load-bearing frame 130 transmitted to the front and rear adjusting pins 17, thus reducing the relative inclination between the axis of the front and rear adjusting pins 17 and the axis of the front and rear adjusting screw holes 151, making it easier and more flexible to rotate the front and rear adjusting pins 17. During assembly, the rear part of the front and rear adjusting pins 17 is first inserted downward into the connecting groove 1402, and then the upper plate 13 is placed on the left and right adjusting seats 15, so that the closing protrusion 1301 closes the connecting groove 1402. The closing protrusion 1301 plays a positioning role for the upper opening of the connecting groove 1402.

[0023] Furthermore, such asFigure 4 As shown, left and right guide protrusions 1503 are formed on the left and right adjustment seat 15, as... Figure 5 As shown, the fixed housing 10 has guide grooves 102, which are distributed at the front and rear ends of the fixed housing 10, as follows: Figure 1 As shown, the left and right guide protrusions 1503 are slidably disposed in the corresponding guide grooves 102. Since the guide grooves 102 are distributed at the front and rear ends of the fixed housing 10, it is beneficial to increase the guiding range of the fixed housing 10 on the left and right adjustment seats 15, enhance the rigidity of the left and right linear movement of the left and right adjustment seats 15, and reduce the swinging situation that occurs when the left and right adjustment seats 15 are adjusted.

[0024] Furthermore, such as Figure 5 As shown, the outer wall of the fixed housing 10 is provided with a scale 1021, such as Figure 4 As shown, a mark 1504 is formed on the left and right guide protrusions 1503. The mark 1504 can be a triangular groove, such as... Figure 1 As shown, the position of mark 1504 corresponds to scale 1021. Therefore, before the fixed housing 10 is installed into the cabinet, the user can see the relative positional relationship between mark 1504 and scale 1021 from the outside, so that the load-bearing frame 130 can be adjusted to the middle position of the adjustment stroke (reset) before the fixed housing 10 is installed into the cabinet.
