Abstract
Description
Technical Field
[0001] This utility model relates to the field of washing machine slow-closing hinge technology, and more particularly to a washing machine slow-closing hinge. Background Technology
[0002] The hinge of a washing machine is a key component that connects the washing machine cabinet and the door. Its core function is to enable the door to rotate (such as opening and closing), while ensuring the sealing performance between the door and the cabinet when the door is closed, so as to prevent water leakage, air leakage and other problems during the washing process.
[0003] Traditional washing machine door hinges have a simple structure, and most washing machine doors do not have a special soft-close design. When users close the washing machine door, the door often moves quickly toward the washing machine body and closes due to its own weight or external force applied by the user. Frequent and rapid collisions can cause wear and tear on the washing machine door and body. For the door, its edges, sealing rings, and the parts connected to the hinge are prone to deformation and damage. For the machine body, the edges that come into contact with the door will also gradually show wear marks, thus affecting the service life of the washing machine. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slow-closing hinge for washing machines.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a washing machine soft-close hinge, including a mounting plate, on which two fixed rods are fixedly connected, and a door hinge is fixedly connected to the fixed rods. A buffer structure is provided on the mounting plate, which mainly consists of a fixed block. The fixed block is fixedly connected to the mounting plate, and a mounting block is provided on the fixed block. A first spring is fixedly connected to the mounting block, and a buffer plate is fixedly connected to one end of the first spring. A rubber pad is fixedly connected to the buffer plate.
[0006] The effect achieved by the above components is as follows: the mounting plate is fixed to the washing machine with bolts, and the two door hinges are inserted into the corresponding mounting holes on the washing machine door. The door can rotate around it to open and close. After the door is closed, the door contacts the buffer plate, compressing the rubber pad and the first spring to deform, absorbing some kinetic energy. Its rebound force acts on the door to achieve buffering and prevent the door from closing quickly. This avoids the situation where the door often moves quickly towards the washing machine body and closes quickly under its own weight or the external force applied by the user when closing the washing machine door. Frequent rapid collisions will cause wear and tear on the washing machine door and body, thus affecting the service life of the washing machine.
[0007] Preferably, the mounting block has two sliding grooves, in which two sliders are slidably connected. A connecting rod is rotatably connected to the slider, and the connecting rod is rotatably connected to the buffer plate.
[0008] The effect achieved by the above components is that the buffer plate is displaced by the collision, which in turn drives the connecting rod to rotate, causing the slider to slide in the groove.
[0009] Preferably, a damping rod is provided in the groove, and the two ends of the damping rod are respectively fixedly connected to two sliders.
[0010] The effect achieved by the above components is that when the two sliders slide, they will cause the damping rod to slide, thereby generating damping force to improve the buffering effect.
[0011] Preferably, the fixing block is provided with an installation structure, which mainly consists of an installation groove. The installation groove is formed on the fixing block and is adapted to the installation block.
[0012] The aforementioned components achieve the following effects: the mounting block can be inserted into the mounting slot to install the buffer assembly, and conversely, it can be removed to facilitate replacement in case of failure.
[0013] Preferably, sliding grooves are provided on the inner walls of both sides of the fixing block, a sliding block is slidably connected in the sliding groove, a sliding rod is fixedly connected to the sliding block, the sliding rod is slidably inserted into the fixing block, and a slot is provided on both sides of the mounting block.
[0014] The effect achieved by the above components is that sliding the two slide rods causes the sliding block to engage in the corresponding slot, which can limit the installation block and make the installation more stable.
[0015] Preferably, a second spring is sleeved on the slide rod, one end of the second spring is fixedly connected to the inner wall of the sliding groove, and the other end of the second spring is fixedly connected to the sliding block.
[0016] The effect achieved by the above components is as follows: when the mounting block is inserted into the mounting groove, the mounting block will push the inclined surfaces of the two sliding blocks, causing them to slide into the sliding groove. At this time, the second spring is in a contracted state. Therefore, when the sliding block contacts the groove, the sliding block will be inserted into the corresponding groove under the action of the rebound force of the second spring, making the installation operation more convenient.
[0017] Preferably, one end of the slide rod is fixedly connected to a connecting rod, a round rod is fixedly connected to the connecting rod, the round rod is slidably connected to the fixing block, a knob is rotatably connected to the fixing block, and an elliptical wheel is fixedly connected to the knob.
[0018] The effect achieved by the above components is that rotating the knob causes the major axis end of the elliptical wheel to push the two round rods to slide, which in turn causes the two sliding blocks to slide out of the slot, making it convenient to disassemble the mounting block.
[0019] Preferably, a third spring is fitted onto the knob, one end of which is fixedly connected to the elliptical wheel, and the other end of which is fixedly connected to the fixing block.
[0020] The effect achieved by the above components is that when the elliptical wheel pushes the two round rods to slide, the third spring is in a twisted state. Therefore, after the knob is released, the elliptical wheel will be reset under the action of the rebound force of the third spring, preventing it from affecting the sliding of the rod.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a buffer structure, the mounting plate is fixed to the washing machine with bolts, and then the two door hinges are inserted into the corresponding mounting holes on the washing machine door. The door can rotate around it to open and close. After the door is closed, the door contacts the buffer plate, compressing the rubber pad and the first spring to deform, absorbing part of the kinetic energy. Its rebound force acts on the door, achieving buffering and preventing the door from closing quickly. This avoids the situation where the door often moves quickly towards the washing machine body and closes quickly under its own weight or the external force applied by the user when closing the washing machine door. Frequent rapid collisions will cause wear and tear on the washing machine door and body, thus affecting the service life of the washing machine. Attached Figure Description

[0029] Example 1, as Figure 1 As shown, the washing machine soft-close hinge includes a mounting plate 1, on which two fixing rods 2 are fixedly connected, and a door hinge 3 is fixedly connected to the fixing rods 2.
[0030] Reference Figure 2 and Figure 3 A buffer structure 4 is provided on the mounting plate 1. The buffer structure 4 mainly consists of a fixing block 41, which is fixedly connected to the mounting plate 1. A mounting block 42 is provided on the fixing block 41, and a first spring 45 is fixedly connected to the mounting block 42. A buffer plate 43 is fixedly connected to one end of the first spring 45, and a rubber pad 44 is fixedly connected to the buffer plate 43. The mounting plate 1 is fixedly installed on the washing machine with bolts. Then, the two door hinges 3 are inserted into the corresponding mounting holes on the washing machine door. The door can rotate around them to open and close. After the door is closed, the door contacts the buffer plate 43, compressing the rubber pad 44 and the first spring 45, causing deformation and absorbing some kinetic energy. The rebound force acts on the door, achieving buffering and preventing the door from closing quickly, thus avoiding the user closing the washing machine. When the door is closed, it often moves rapidly toward the washing machine body under its own weight or external force applied by the user and eventually closes. Frequent rapid collisions can cause wear and tear on the washing machine door and body, thus affecting the lifespan of the washing machine. The mounting block 42 has two sliding grooves 46, in which two sliders 47 are slidably connected. A connecting rod 48 is rotatably connected to the slider 47. The connecting rod 48 is rotatably connected to the buffer plate 43. When the buffer plate 43 is impacted, it is displaced, which in turn drives the connecting rod 48 to rotate, causing the slider 47 to slide in the sliding groove 46. A damping rod 49 is provided in the sliding groove 46. The two ends of the damping rod 49 are fixedly connected to the two sliders 47 respectively. When the two sliders 47 slide, they will drive the damping rod 49 to slide, thereby generating a damping force to improve the buffering effect.
[0031] Reference Figure 4 and Figure 6The fixed block 41 is provided with an installation structure 5, which mainly consists of an installation groove 51. The installation groove 51 is formed on the fixed block 41 and is adapted to the installation block 42. The installation block 42 can be inserted into the installation groove 51 to install the buffer component, and vice versa, it can be removed for easy replacement if it fails. Sliding grooves 52 are respectively formed on the inner walls of both sides of the fixed block 41. Sliding blocks 53 are slidably connected in the sliding grooves 52. Sliding rods 55 are fixedly connected to the sliding blocks 53 and are slidably inserted into the fixed block 41. On the upper part, mounting block 42 has slots 54 on both sides. Sliding two sliding rods 55 causes sliding block 53 to engage in the corresponding slots 54, which can limit the mounting block 42 and make the installation more stable. A second spring 56 is sleeved on the sliding rod 55. One end of the second spring 56 is fixedly connected to the inner wall of the sliding groove 52, and the other end of the second spring 56 is fixedly connected to the sliding block 53. When mounting block 42 is engaged in the mounting groove 51, mounting block 42 will push the inclined surfaces of the two sliding blocks 53, causing them to slide into the sliding groove 52. At this time, the second spring 56 is engaged in the mounting groove 52. When spring 56 is in a contracted state, the sliding block 53 contacts the slot 54, and under the action of the rebound force of the second spring 56, the sliding block 53 is engaged in the corresponding slot 54, making the installation operation more convenient. One end of the sliding rod 55 is fixedly connected to a connecting rod 57, and a round rod 58 is fixedly connected to the connecting rod 57. The round rod 58 is slidably connected to the fixing block 41. A knob 59 is rotatably connected to the fixing block 41, and an elliptical wheel 510 is fixedly connected to the knob 59. Rotating the knob 59 causes the long axis end of the elliptical wheel 510 to push the two round rods 54. 8. Sliding can cause the two sliding blocks 53 to slide away from the slot 54, making it easy to disassemble the mounting block 42. A third spring 511 is fitted on the knob 59. One end of the third spring 511 is fixedly connected to the elliptical wheel 510, and the other end of the third spring 511 is fixedly connected to the fixing block 41. When the elliptical wheel 510 pushes the two round rods 58 to slide, the third spring 511 is in a twisted state. Therefore, after the knob 59 is released, the elliptical wheel 510 will be reset under the action of the rebound force of the third spring 511, so as to prevent affecting the sliding of the sliding rod 55.
[0032] Working principle: The mounting plate 1 is fixed to the washing machine with bolts. Two door hinges 3 are then inserted into the corresponding mounting holes on the washing machine door, allowing the door to rotate and open / close. When the door is closed, it contacts the buffer plate 43, compressing the rubber pad 44 and the first spring 45, causing deformation and absorbing some kinetic energy. The rebound force acts on the door, buffering and preventing the door from closing too quickly. This avoids the door from rapidly approaching and closing under its own weight or external force applied by the user, which can cause wear and tear on the door and machine body, affecting the washing machine's lifespan. The buffer plate 43 is displaced by the impact, causing the connecting rod 48 to rotate, which in turn causes the slider 47 to slide in the groove 46. The sliding of the two sliders 47 drives the damping rod 49 to slide, generating damping force to improve the buffering effect. The mounting block 42 is then inserted into the mounting slot 51 to install the buffer assembly. It can be removed for easy replacement in case of failure. Sliding the two slide rods 55 causes the sliding block 53 to engage in the corresponding slot 54, which limits the installation block 42 and makes the installation more stable. When the installation block 42 engages in the installation slot 51, the installation block 42 will push the inclined surfaces of the two sliding blocks 53, causing them to slide into the sliding slot 52. At this time, the second spring 56 is in a contracted state. Therefore, when the sliding block 53 contacts the slot 54, the sliding block 53 is subjected to the rebound force of the second spring 56. The elliptical wheel 510 is inserted into the corresponding slot 54, making the installation operation more convenient. Rotating the knob 59 causes the long axis end of the elliptical wheel 510 to push the two round rods 58 to slide, which in turn drives the two sliding blocks 53 to slide away from the slot 54, making it easier to disassemble the mounting block 42. When the elliptical wheel 510 pushes the two round rods 58 to slide, the third spring 511 is in a twisted state. Therefore, after releasing the knob 59, the elliptical wheel 510 will be reset under the action of the rebound force of the third spring 511, preventing it from affecting the sliding of the sliding rod 55.
