Description

Technical Field

[0001] This utility model relates to the technical field of hinges, and in particular to a hinge. Background Technology

[0002] Hinges are devices used to connect doors, windows, cabinets, and other items requiring mechanical connection. They typically consist of two or more moving parts. Hinges are installed on items that need to rotate relative to each other, allowing these items to rotate. Cup hinges are a type of hinge, usually installed between the door panel and the cabinet body of cabinet products, allowing relative rotation between the door panel and the cabinet body. Cup hinges consist of a cup head and an arm body, which are hinged together and can rotate relative to each other. Cup hinges usually have a buffer component that cushions the relative rotation of the cup head and the arm body, reducing the impact of the hinge movement. The impact force generated when the chain drives the door panel and cabinet to close acts as a buffer and damping mechanism for the rotation between the door panel and the cabinet. However, in current hinges, the buffer component is assembled in the arm body. The disadvantage of placing the buffer component in the arm body is that it results in a larger number of parts in the arm body. In addition, the arm body usually has an adjustment component to adjust the length of the arm body, which means that the arm body needs to be designed to be larger in size to accommodate the installation of parts. On the other hand, the cup head has fewer parts, so it does not need to be larger in size. The volume difference between the arm body and the cup head exacerbates the imbalance in volume and weight between the arm body and the cup head.

[0003] Therefore, in order to solve the above problems, this utility model provides a hinge. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hinge.

[0005] To achieve the above objectives, this utility model discloses a hinge, including a cup head, an arm body, and a buffer member. The cup head is hinged to the arm body, and the buffer member is connected to the cup head. When the arm body and the cup head rotate toward the closed state, the buffer member abuts against the arm body, and the buffer member applies a buffering force to the arm body. The buffering force is set opposite to the rotation direction of the arm body.

[0006] A further embodiment is that the buffer is a cylinder-type buffer, the cylinder of the buffer is connected to the cup head, and when the arm body and the cup head rotate toward the closed state, the rod of the buffer abuts against the arm body.

[0007] A further embodiment includes a spring, which is assembled with the cup head. When the arm and the cup head rotate toward the open state, the spring force acts on the cup head and the buffer to drive the buffer to reset.

[0008] A further embodiment includes a slider that is slidably connected to the outer wall of the cup head. A buffer is connected between the cup head and the slider. When the arm and the cup head rotate to the closed state, the slider abuts against the arm and drives the slider to slide relative to the outer wall of the cup head. The buffer applies the buffering force to the arm through the slider.

[0009] A further embodiment is that the sliding member is slidably connected to the outer bottom surface of the cup head, the bottom wall of the cup head has a through hole, the sliding member has an abutment part, the abutment part is provided through the sliding member through the through hole, and when the arm body and the cup head rotate toward the closed state, the abutment part abuts against the arm body.

[0010] A further embodiment includes a spring, wherein the sliding member has a first mounting portion that protrudes from the top surface of the sliding member, and the spring is connected between the first mounting portion and the cup head. When the arm and the cup head rotate toward the open state, the spring drives the buffer to reset.

[0011] A further embodiment is that the spring is a compression spring, the assembly direction of the spring is parallel to the reset sliding direction of the slider, one end of the spring is connected to the cup head, and the other end of the spring is connected to the first assembly part. When the arm body and the cup head rotate to the closed state, the slider compresses the spring.

[0012] A further embodiment is that the slider is provided with a second mounting part, the second mounting part protruding from the top surface of the slider, and the buffer is connected between the second mounting part and the cup head.

[0013] A further embodiment is that the slider is provided with a reset part, the reset part and the abutting part are spaced apart along the rotation path of the arm body, the arm body and the reset part abut against each other through the through hole, and when the arm body and the cup head rotate toward the open state, the arm body abuts against the reset part to drive the slider to reset.

[0014] A further embodiment includes a housing, which is fixedly fitted onto the outside of the cup head. The sliding member is slidably connected between the inner bottom surface of the housing and the outer bottom surface of the cup head, or the housing abuts against the spring, or the housing abuts against the buffer member.

[0015] A further embodiment includes an abutment member, which is fixedly connected to one end of the arm body near the cup head. When the arm body and the cup head rotate toward the closed state, the abutment member abuts against the sliding member, and / or when the arm body and the cup head rotate toward the open state, the abutment member abuts against the sliding member.

[0016] A further embodiment is that the outer bottom surface of the cup head is recessed with a first mounting groove or a second mounting groove, the first mounting groove extends to the outer side surface of the cup head, the second mounting groove extends to the outer side surface of the cup head, the spring is installed in the first mounting groove, and the buffer is installed in the second mounting groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the cup head is screwed onto one panel of the door cabinet product, and the arm body is screwed onto the other panel of the door cabinet product, so that the two panels can rotate relative to each other. The buffer is connected to the cup head. When the arm body and the cup head move from the open state to the closed state, the door panel of the door cabinet product closes, and the buffer is in contact with the arm body. The buffer can apply a buffering force to the rotation of the arm body to reduce the impact force when the two panels of the door cabinet product close and collide. Because the buffer is connected to the cup head, the number of parts of the arm body is reduced, so that the size of the arm body can be reduced when designing the size of the arm body, making the structure of the arm body more compact, reducing the volume difference between the arm body and the cup head, improving the uniformity of volume and weight between the arm body and the cup head, and improving the convenience of installing the hinge.

[0018] When the cup head and arm rotate from the closed state to the open state, the door panel of the cabinet product opens. The spring applies elastic force to the buffer to drive the sliding part and the buffer to return to their original positions. The buffer can then apply buffering force to the arm again, so that the buffer can provide buffering force to the hinge during repeated use, and provide buffering force to the cabinet product that is repeatedly closed.

[0019] Both the spring and the reset part serve to drive the slider to reset. However, after long-term and repeated use, or when the hinge is used in an environment with a lot of oil stains, the spring may fail to drive the slider to reset, thus the spring may not be able to drive the slider to reset. In this case, the arm can abut against the reset part to drive the slider to reset, thereby driving the slider and the buffer to reset, reducing the risk that the slider may not be able to reset.

[0039] To address the issue that the large number of parts installed on the arm due to the buffer component being located on the arm body necessitates a larger arm body design to accommodate the buffer component, resulting in inconvenience when installing hinges on products such as doors, cabinets, and windows, this invention provides a hinge to reduce the length of the arm body.

[0040] It should be noted that the cup head and arm body in the description of this utility model are in the closed and open states, that is, the closed and open states of the hinge. The above states refer to the opening and closing states of the door and window when the hinge is installed on products such as doors, cabinets, and windows. The closed state refers to the closed state of the door and window of the above products, and the open state refers to the open state of the door and window of the above products. The angle between the arm body and the cup head in the closed state is approximately 90°, and the angle between the arm body and the cup head in the open state is approximately 180°.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, this utility model is based on... Figure 1 , Figure 7 The hinge positions and orientations are defined using terms such as "top" and "bottom"; secondly, this utility model uses... Figure 7 The directions indicated by "X", "Y" and "Z" in the coordinate axes described herein describe the sliding direction of the relevant components of this utility model; the above-mentioned directional terms and related states are all for the purpose of making the description of this embodiment clearer, and should not be regarded as limiting the technical features of this utility model by installing the hinge on the above-mentioned product.

[0042] The following will combine Figure 1-18 The accompanying drawings provide a further detailed description of this utility model.

[0043] A hinge includes a cup head 11, an arm body 12, and a buffer 13. The cup head 11 is hinged to the arm body 12, and the cup head 11 rotates relative to the arm body 12. In use, the cup head 11 is screwed onto one panel of a door cabinet product, and the arm body 12 is screwed onto the other panel of the door cabinet product, allowing the two panels to rotate relative to each other. The buffer 13 is connected to the cup head 11. When the arm body 12 and the cup head 11 move from an open state to a closed state, that is, when the two panels rotate relative to each other and in the direction of the 90° angle between the two panels, the door panel of the door cabinet product is closed. 3. The buffer 13 abuts against the arm body 12 and can apply a reverse force to the arm body 12. This reverse force is a buffering force. The direction of the buffering force is opposite to the relative rotation of the arm body 12 and the cup head 11. So when the arm body 12 and the cup head 11 rotate toward the closed state, the buffer 13 abuts against the arm body 12 and applies a reverse force, reducing the impact force when the two panels of the door cabinet product close and collide. Since the buffer 13 is connected to the cup head 11, the number of parts installed on the arm body 12 is reduced and the size of the arm body 12 is shortened.

[0044] Connecting the buffer 13 to the cup head 11 reduces the number of parts in the arm body 12, allowing for a smaller arm body 12 size design, making the arm body 12 structure more compact, reducing the volume difference between the arm body 12 and the cup head 11, improving the uniformity of volume and weight between the arm body 12 and the cup head 11, and enhancing the ease of hinge installation.

[0045] This embodiment also includes a spring 14, which drives the buffer 13 to reset. The assembly direction of the spring 14 is parallel to the reset direction of the buffer 13. One end of the spring 14 is connected to the cup head 11, and the other end of the spring 14 abuts against the buffer 13. When the two plates rotate from a 180° angle to a 90° angle, and the cup head 11 and the arm body 12 rotate from the closed state to the open state, that is, when the cup head 11 and the arm body 12 rotate from a 180° angle to a 90° angle, the spring 14 applies a spring force to the buffer 13, and the spring 14 drives the buffer 13 to reset. When the buffer 13 resets, it means that when the cup head 11 and the arm body 12 rotate from the open state to the closed state, the buffer 13 can apply a buffering force to the arm body 12 again. Through the above settings, the buffer 13 can provide a buffering force to the hinge during repeated use.

[0046] This embodiment also includes a slider 15, a buffer 13 is a cylinder-type buffer, the outer wall of the cup head 11 is slidably connected to the slider 15, the rod 34 of the buffer 13 is fixedly connected to the slider 15, and the cylinder 35 of the buffer 13 is fixedly connected to the cup head 11. When the arm body 12 and the cup head 11 rotate from the open state to the closed state, the arm body 12 applies a force to the slider 15, driving the slider 15 to slide on the outer wall of the cup head 11. At the same time, the moving slider 15 applies a force to the rod 34, causing the rod 34 to move relative to the cylinder 35. The cylinder 35 provides a buffering force to the rod 34, thereby enabling the buffer 13 to provide a buffering force opposite to the sliding direction of the slider 15, allowing the buffer 15 to provide a buffering force to the arm body through the slider 15. The rotation of 12 provides a buffering force, which is opposite to the rotation direction of the arm body 12. That is, the buffering force is a reversing force opposite to the relative rotation direction of the arm body 12 and the cup head 11. The spring 14 is connected between the slider 15 and the cup head 11. When the arm body 12 and the cup head 11 rotate from the closed state to the open state, the spring 14 applies a spring force to the slider 15, driving the slider 15 to slide relative to the cup head 11 in the direction of the slider 15's reset. The spring 14 drives the slider 15 to reset, so that when the arm body 12 and the cup head 11 rotate from the open state to the closed state, the slider 15 can abut against the arm body 12 again, so as to provide a buffering force for the rotation of the arm body 12 to the closed state again. The buffer 13 can provide a buffering force for the rotation of the arm body 12 through the slider 15.

[0047] When the arm body 12 and the cup head 11 rotate from the open state to the closed state, the arm body 12 rotating towards the closed state abuts against the slider 15, and during the process of the buffer 13 applying a buffering force to the arm body 12 through the slider 15, the slider 13 simultaneously drives the spring 14, which increases the elastic potential energy of the spring 14, so that when the arm body 12 rotates towards the open state, the spring 14 drives the slider 15 to reset again.

[0048] Specifically, in this embodiment, the top surface of the slider 15 is slidably connected to the outer bottom surface of the cup head 11. The bottom wall of the cup head 11 has a through hole 19. The slider 15 has an abutment portion 20, which extends upward from the top surface of the slider 15 and passes through the through hole 19. When the slider 15 is driven by the arm body 12 or by the spring 14, the abutment portion 20 moves within the through hole 19. When the arm body 12 and the cup head 11 rotate from the open state to the closed state, the abutment portion 20 abuts against the arm body 12, thereby driving the slider 15 to move in the X direction. The buffer 13 applies a buffering force to the moving slider 15, thereby the buffer 13 provides a buffering force through the slider 15's rotation of the arm body 12.

[0049] The slider 15 is provided with a first mounting part 21, which extends upward from the slider 15. The outer bottom surface of the cup head 11 is recessed with a first mounting groove 22, which extends to the outer side surface of the cup head 11. The spring 14 is connected between the first mounting part 21 and the cup head 11 and is installed in the first mounting groove 22. When the arm body 12 and the cup head 11 rotate from the open state to the closed state, the slider 15 is driven by the arm body 12 to slide in the X direction on the outer bottom surface of the cup head 11. The first mounting part 21 moves in the first mounting groove 22 and applies a force to the spring 14, so that the spring 14 has elastic potential energy.

[0050] The sliding member 15 is provided with a second mounting part 23, which extends upward from the sliding member 15. The outer bottom surface of the cup head 11 is recessed with a second mounting groove 24. The first mounting part 21 and the second mounting part 23 are spaced apart, and the first mounting groove 22 and the second mounting groove 24 are spaced apart. The second mounting groove 24 extends to the outer side surface of the cup head 11. The buffer member 13 is installed in the second mounting groove 24. The second mounting part 23 is connected to the rod 34 of the buffer member 13 in the second mounting groove 24, and the second mounting part 23 can move in the second mounting groove 24. When the arm body 12 and the cup head 11 rotate from the open state to the closed state, the sliding member 15 is driven by the arm body 12 to slide in the X direction on the bottom surface of the cup head 11. The second mounting part 23 slides in the X direction in the first mounting groove 22, and the buffer member 13 applies a buffering force to the sliding member 15 through the second mounting part 23, thereby applying a buffering force to the arm body 12.

[0051] When the arm body 12 and the cup head 11 rotate from the closed state to the open state, the arm body 12 separates from the slider 15, that is, the arm body 12 no longer applies a resisting force to the slider 15. The spring 14 with elastic potential energy can drive the slider 15 to slide in the opposite direction of the X direction, thereby resetting the slider 15. At the same time, the first assembly part 21 and the second assembly part 23 slide in the opposite direction of the X direction in the first assembly groove 22 and the second assembly groove 24, respectively.

[0052] In this embodiment, the slider 15 is provided with a reset part 25. The reset part 25 protrudes upward from the slider 15, that is, the reset part 25 is arranged to protrude towards the through hole 19. The reset part 25 passes through the through hole 19 and can abut against the arm body 12. When the arm body 12 and the cup head 11 rotate from the closed state to the open state, the arm body 12 passes through the through hole 19 and abuts against the reset part 25. The arm body 12 abuts against the reset part 25 and drives the slider 15 to reset, that is, the slider 15 slides in the opposite direction of the X direction on the bottom surface of the cup head 11. Both the spring 14 and the reset part 25 drive the slider 15 to reset. The function of the 5-fold reset mechanism is to prevent the spring 14 from failing to drive the slider 15 to reset if the hinge has been used repeatedly for a long time or in an environment with a lot of oil stains. In this case, the spring 14 may not be able to drive the slider 15 to reset. The arm body 12 can abut against the reset mechanism 25 to drive the slider 15 to reset in the opposite direction of X, providing the starting force for the slider 15 to slide, overcoming the difficulty of starting the sliding due to the stickiness of the oil stains on the slider 15, and reducing the risk that the slider 15 cannot reset.

[0053] This embodiment also includes a housing 26, which is fixedly sleeved on the outside of the cup head 11. The sliding member 15 slides between the inner bottom surface of the housing 26 and the outer bottom surface of the cup head 11. One end of the spring 14 is connected to the first assembly part 21, and the other end of the spring 14 abuts against the housing 26. The housing 26 is fixedly connected to the cup head 11, so that the spring 14 can abut against the sliding member 15 and the cup head 11. The buffer member 13 is installed between the sliding member 15 and the cup head 11. The rod 34 of the buffer member 13 abuts against the second assembly part 23, and the round bottom surface of the cylinder 35 of the buffer member 13 abuts against the housing 26.

[0054] This embodiment also includes an abutment 33, which abuts against the abutment portion 20 of the slider 15. The abutment 33 is fixedly connected to one end of the arm body 12 near the cup head 11. When the arm body 12 and the cup head 11 rotate from the open state to the closed state, the abutment 33 rotates relative to the cup head 11. The rotating abutment 33 abuts against the abutment portion 20 of the slider 15, thereby causing the abutment 33 to slide between the outer bottom surface of the cup head 11 and the inner bottom surface of the outer shell 26 in a direction closer to the arm body 12.

[0055] It should be further explained that the abutment 33 is also used to abut against the reset part 25 of the slider 15. When the arm body 12 and the cup head 11 rotate from the closed state to the open state, the abutment 33 rotates relative to the cup head 11. The rotating abutment 33 abuts against the reset part 25 of the slider 15, thereby driving the slider 15 to slide away from the arm body 12 between the outer bottom surface of the cup head 11 and the inner bottom surface of the outer shell 26.

[0056] The top surface of the slider 15 is T-shaped, and a clearance hole 16 is provided in the slider 15, extending from the top surface to the bottom surface of the slider 15. The clearance hole 16 is located near the foot 17 of the slider 15. The abutment 33 rotates back and forth within the clearance hole 16. The foot 17 of the slider 15 is raised towards the through hole 19. The abutment 20 is located on the foot 17 of the slider 15, and protrudes towards the reset part 25 from the foot 17. The positioning part 25 is connected to the side of the relief hole 16 and is positioned opposite to the abutment part 20. The reset part 25 is a hook-shaped body facing the abutment part 20. The first assembly part 21 and the second assembly part 23 are respectively raised from both sides of the top cap 18 of the slider 15 toward the cup head 11. The first assembly part 21 extends into the first assembly groove 22 and is connected to the spring 14. The second assembly part 23 extends into the second assembly groove 24 and is fixedly connected to the rod 34 of the buffer 13. The foot 17 of the slider 15 slides back and forth in the through hole 19.

[0057] The inner bottom surface of the outer shell 26 is recessed with a sliding groove 27. The width of the sliding groove 27 in the Y direction is adapted to the width of the sliding member 15 in the Y direction. The sliding groove 27 guides the sliding of the sliding member 15. When the outer shell 26 is assembled with the cup head 11, the sliding member 15 can slide back and forth in the sliding groove 27, that is, the sliding member 15 can slide back and forth between the bottom surface of the sliding groove 27 and the outer bottom surface of the cup head 11.

[0058] This embodiment also includes a hinge 28 for hinged connection of cup head 11 and arm body 12. The hinge 28 is U-shaped. The outer side of the outer shell 26 is recessed with a relief groove 29. The relief groove 29 and the hinge 28 are adapted to each other. The bottom surface of the relief groove 29 is provided with a hinge hole 30. The hinge 28 passes into the relief groove 29 and through the hinge hole 30 so that the cup head 11 and arm body 12 are hinged together.

[0059] The bottom wall of the outer shell 26 has a hollow hole 31, which corresponds to the position of the buffer 13. When the outer shell 26 is assembled with the cup head 11, part of the buffer 13 is located in the hollow hole 31. The side wall of the hollow hole 31 is provided with a limiting part 32 for limiting the buffer 13. The limiting part 32 protrudes from the side wall of the hollow hole 31 and abuts against the side wall of the cylinder 35 of the buffer 13 so that the buffer 13 is limited between the lower side of the limiting part 32 and the bottom surface of the hollow hole 31.

[0060] The abutment 33 has an arc-shaped groove 36 recessed on the side facing the hinge 28. The extension direction of the arc-shaped groove 36 is parallel to the extension direction of the straight section of the hinge 28. The radius of the arc-shaped groove 36 is equal to the radius of the straight section of the hinge 28. When the abutment 33 is assembled with the arm body 12, the straight section of the hinge 28 is fixedly embedded in the arc-shaped groove 36. The abutment 33 also has a protrusion 37, which protrudes outward from the top of the abutment 33. The protrusion 37 is used to abut with the abutment 20 and the reset part 25.
