Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a damper mounting structure and hinge. Background Technology

[0002] A hinge is a mechanical device used to connect two objects and allow relative rotation between them. It includes a hinge cup, a hinge body, and a hinge seat, and is commonly used in places where frequent opening and closing is required, such as between cabinets and cabinet doors. In the prior art, hinges include ordinary hinges and damper hinges.

[0003] Among them, damper hinges are made by adding a damper inside the hinge body, which is connected to the hinge cup to buffer the opening and closing of the cabinet door and reduce noise. However, in the existing technology, the damper is usually placed directly inside the hinge body and fixed at both ends by pins. The damper has no guide limit during the extension and retraction movement, the damper itself lacks protection, is easy to be damaged, has low overall strength, and a short service life. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a damper mounting structure and hinge to improve the problems of insufficient protection and poor strength in damper mounting in existing technologies.

[0005] This utility model provides a damper mounting structure, comprising: Hinge; A housing, installed within the hinge to accommodate a damper, the housing having an opening for the moving end of the damper to extend out; A sliding element is slidably mounted in the hinge body and connected to the moving end of the damper; A travel limit structure is fixedly installed on the outside of the box to limit the travel of the slider away from the box.

[0006] As can be seen from the above technical solution, this utility model houses the damper inside the box, which protects the damper. The structure is simple. The box is installed inside the hinge, which reduces the swaying of the damper when it extends and retracts. The box can also be used as a liner for the hinge, which improves the overall strength and extends the service life.

[0007] Furthermore, grooves are provided on both outer walls of the box body that are parallel to the direction of movement of the damper's moving end, and the sliding member slides in the two grooves on both sides respectively.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the groove guides the sliding of the sliding component.

[0009] Furthermore, both ends of the slider located within the groove are fixedly provided with protrusions.

[0010] The beneficial effect of adopting the above-mentioned further solution is that it allows an external driving component to drive the sliding component.

[0011] Furthermore, the travel limiting structure includes a limiting platform and a hanging platform; The sliding member is fixedly provided with a hanging platform at both ends of the sliding groove. A limiting platform corresponding to the hanging platform is fixedly provided on the side wall of the sliding groove. When the damper is in the extended state, the hanging platform abuts against the limiting platform.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it limits the stroke of the slider, preventing the slider and damper from coming off the housing.

[0013] Furthermore, one end of the box body is rotatably mounted in the hinge body via a first rotating shaft, and the other end of the box body is provided with an arc-shaped slot for fixing the box body, the axis of the arc-shaped slot being parallel to the first rotating shaft.

[0014] The advantages of adopting the above-mentioned further solution are: the box body is fixed in the hinge body to avoid shaking, the installation structure is simple, and it is easy to assemble and disassemble.

[0015] Furthermore, the box body has an exhaust vent on the side away from the opening that communicates with the interior of the box body.

[0016] The advantage of adopting the above-mentioned further solution is that it avoids the formation of a closed cavity inside the box, which would make it difficult to disassemble and assemble the damper.

[0017] Furthermore, the box body is fixedly provided with several protruding strips on one side facing the hinge body.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it adjusts the height and spatial position of the box body within the hinge to adapt to the cooperation with various components.

[0019] A hinge includes the damper mounting structure described above, and further includes a hinge cup, a first hinge arm, and a second hinge arm. One end of the first hinge arm is rotatably connected to the hinge body via a second pivot, and the other end is rotatably connected to the hinge cup via a third pivot. A torsion spring is provided on the second pivot. One end of the second hinge arm is rotatably connected to the hinge cup via a fourth pivot, and the other end is rotatably connected to the hinge body via a fifth pivot and is fixedly provided with a hook portion. When the hook portion rotates around the fifth pivot, the hook portion contacts the protrusion portion and drives the damper to contract.

[0020] The beneficial effects of adopting the above scheme are: setting a box inside the hinge to house the damper reduces the swaying when the damper extends and retracts, and transmits the torque when the second hinge arm rotates to the damper. The damper reduces the impact force when the hinge opens and closes, and reduces noise.

[0021] Furthermore, the hinge body is provided with a mounting bracket for mounting the hinge seat.

[0022] The advantage of adopting the above-mentioned further solutions is that different sizes of hinge seats can be replaced according to the usage scenario, making it more applicable.

[0023] Furthermore, a dovetail buckle is provided on one side of the card holder.

[0024] The advantages of adopting the above-mentioned further solutions are: the dovetail buckle structure is simple, and the disassembly and replacement of the hinge seat are more convenient. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] Example 1 like Figures 1 to 3 As shown, a damper mounting structure includes: Hinge 1; The housing 2 is installed inside the hinge 1 to accommodate the damper 3. The housing 2 is provided with an opening 4 for the moving end of the damper 3 to extend out. The sliding member 5 is slidably installed in the hinge 1 and connected to the moving end of the damper 3; A travel limit structure is fixedly installed on the outside of the box 2 to limit the travel of the slider 5 away from the box 2.

[0030] In this embodiment, a receiving cavity is provided inside the box body 2, and the damper 3 is placed in the receiving cavity. The moving end of the damper 3 extends out from the opening 4 and is fixedly connected to the sliding member 5. Under the action of external force, the sliding member 5 pushes the damper 3 to retract. During the retraction process, the damper 3 consumes kinetic energy and plays a buffering role. After the external force disappears, the damper 3 resets and pushes the slider 5 to move away from the box 2. The stroke limit structure prevents the slider 5 from detaching from the box 2 after it moves.

[0031] Based on this embodiment, the travel limiting structure can be a baffle fixed outside the box 2, with the other end of the baffle extending in the sliding direction of the slider 5. When the slider 5 moves a certain distance away from the box 2, the baffle blocks the slider 5 to limit its movement.

[0032] Example 2 like Figures 1 to 3 As shown, preferably, based on embodiment 1, the outer walls of the box body 2 and the damper 3, which are parallel to the direction of movement of the moving end, are provided with sliding grooves 6, and the sliding member 5 is slidably located in the two sliding grooves 6 on both sides respectively.

[0033] like Figures 1 to 3 As shown, the sliding member 5 is provided with protrusions 7 at both ends located in the sliding groove 6.

[0034] like Figures 1 to 3 As shown, the travel limiting structure includes a limiting platform 8 and a hanging platform 9; The sliding member 5 is slidably located in the slide groove 6, and both ends are fixedly provided with a hanging platform 9. The side wall of the slide groove 6 is fixedly provided with a limiting platform 8 corresponding to the hanging platform 9. When the damper 3 is in the extended state, the hanging platform 9 abuts against the limiting platform 8.

[0035] like Figures 1 to 3As shown, one end of the box body 2 is rotatably mounted in the hinge body 1 via the first rotating shaft 10, and the other end of the box body 2 is provided with an arc-shaped slot 11 for fixing the box body 2. The axis of the arc-shaped slot 11 is parallel to the first rotating shaft 10.

[0036] like Figures 1 to 3 As shown, the box body 2 has an exhaust hole 12 on the side away from the opening 4, which communicates with the interior of the box body 2.

[0037] like Figures 1 to 3 As shown, the box body 2 is fixedly provided with several protrusions 13 on the side facing the hinge body 1.

[0038] In this embodiment, when an external force comes into contact with the protrusion 7, it pushes the slider 5 to slide towards the box 2. Both ends of the slider 5 slide in the groove 6 along its length. The groove 6 has a guiding function, so that the force is transmitted more accurately to the moving end of the damper 3 until the damper 3 is compressed. When the external force disappears, the damper 3 resets and pushes the slider 5 to move away from the box 2 along the slide groove 6. After moving a certain distance, the mounting platform 9 of the slider 5 engages with the limiting platform 8 to limit the slider 5.

[0039] In addition, the hinge 1 has a U-shaped cross-section, and the box 2 is placed in the groove of the hinge 1. The side of the box 2 away from the bottom of the groove of the hinge 1 is provided with a first rotating shaft 10 and an arc-shaped slot 11. During installation, the arc-shaped slot 11 of the box body 2 is first abutted against a certain position inside the hinge body 1 to prevent the box body 2 from moving. Then, the first rotating shaft 10 is inserted. The combination of the first rotating shaft 10 and the arc-shaped slot 11 fixes the box body 2. The structure is simple and easy to assemble and disassemble.

[0040] In addition, the protrusion 13 on the box body 2 abuts against the bottom of the groove of the hinge 1. The height of the protrusion 13 is pre-designed when manufacturing the box body 2 to adjust the height space of the box body 2 in the groove of the hinge 1, so as to adapt to the cooperation with various components.

[0041] Example 3 like Figures 4 to 8 As shown, preferably, based on embodiments 1-2, a hinge includes the damper mounting structure described above, and also includes a hinge cup 14, a first hinge arm 15 and a second hinge arm 19. One end of the first hinge arm 15 is rotatably connected to the hinge body 1 via a second pivot 16, and the other end is rotatably connected to the hinge cup 14 via a third pivot 17. A torsion spring 18 is provided on the second pivot 16. One end of the second hinge arm 19 is rotatably connected to the hinge cup 14 via the fourth pivot 20, and the other end is rotatably connected to the hinge body 1 via the fifth pivot 21 and is fixedly provided with a hook portion 22. When the hook portion 22 rotates around the fifth pivot 21, the hook portion 22 contacts the protrusion 7 and drives the damper 3 to contract.

[0042] like Figure 8 As shown, the hinge body 1 is provided with a mounting bracket 23 for mounting the hinge seat.

[0043] like Figure 8 As shown, a dovetail buckle 24 is provided on one side of the card holder 23.

The second hinge arm 19 is installed on the inside of the first hinge arm 15. The first hinge arm 15 and the second hinge arm 19 connect the hinge cup 14 and the hinge body 1. refer to Figure 4 and Figure 5 When the cabinet door is opened, the hinge cup 14 is in the open state, the damper 3 is in the released state, the damper 3 pushes the sliding member 5 to move away from the box body 2, the first hinge arm 15 and the second hinge arm 19 are located outside the hinge cup 14, and the hook part 22 does not contact the protrusion 7. refer to Figure 6 and Figure 7 When the cabinet door is closed, the hinge cup 14 gradually enters the folding state, and the first hinge arm 15 and the second hinge arm 19 gradually retract into the recessed position of the hinge cup 14. During this process, the second hinge arm 19 and the hook part 22 rotate around the fifth pivot 21. The hook part 22 contacts the protrusion 7 of the sliding member 5 and drives the protrusion 7 to slide in the slide groove 6. The protrusion 7 drives the sliding member 5 to move towards the hinge cup 14. When the sliding member 5 moves, it compresses the damper 3. The damping effect of the damper 3 itself acts on the cabinet door to reduce the noise of closing the door.

[0045] In addition, the hinge body 1 is provided with a retaining seat 23 and a dovetail buckle 24. The two ends of the hinge body in the length direction are respectively engaged between the retaining seat 23 and the dovetail buckle 24. A reset torsion spring is provided on the inner side of the dovetail buckle 24. The hinge body can be removed by pressing the dovetail buckle 24.
