Description

Technical Field

[0001] This utility model relates to the field of hinge technology for drum washing machines, and more particularly to hinges for drum washing machines. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can consist of movable components or be made of foldable materials. Hinges are most commonly installed on cabinets and are mainly classified by material into stainless steel hinges and iron hinges. To provide a better user experience, hydraulic hinges (also known as damping hinges) have emerged. Their characteristic is that they provide a buffer function when the cabinet door closes, minimizing the noise generated by the door colliding with the cabinet body. Hinges are often used to connect the doors of front-loading washing machines.

[0003] The inventors discovered during daily use of hinges that the surface of the fixing post on a typical hinge is smooth and lacks a limiting component. Consequently, after being installed on the surface of the washing machine door, it cannot effectively lock and engage the door, making it inconvenient to install the door with the hinge and causing problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hinge for a drum washing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drum washing machine hinge, including a hinge, a connecting plate provided on the side of the hinge, a fixing post fixedly connected to the surface of the connecting plate, a fixing device provided on the surface of the fixing post, the fixing device including a conical block fixedly connected to the surface of the fixing post, the conical block being a rubber block.

[0006] The effect achieved by the above components is as follows: under the action of the conical block, the fixing post can be fixed inside the washing machine door, thereby achieving the function of fixing the door. When the hinge is needed, the hinge is placed in a suitable position on the side of the drum washing machine and fixed to the side of the drum washing machine with screws. The door is fixed to the surface of the hinge through the fixing post, thereby allowing the washing machine door to be installed together with the washing machine, and the washing machine can then be used.

[0007] Preferably, the surface of the fixed column is provided with a circular groove, and a ball bearing is rotatably connected inside the circular groove.

[0008] The effect achieved by the above components is that, under the action of the ball bearings, the machine door can rotate smoothly on the surface of the fixed column, avoiding the phenomenon of the machine door jamming.

[0009] Preferably, one end of the fixing column is provided with a bolt, which is screwed into the interior of the fixing column.

[0010] The effect achieved by the above components is that, under the action of the bolts, the machine door will not slip off the surface of the fixing column, thereby achieving the function of fixing the machine door.

[0011] Preferably, one end of the bolt is fixedly connected to a washer, and the washer is a rubber plate.

[0012] The effect achieved by the above components is that, under the action of the pad, the machine door will not come into contact with the bolts, thus avoiding the phenomenon of rigid contact.

[0013] Preferably, the surface of the connecting plate is provided with a groove, and a ball is rotatably connected inside the groove.

[0014] The aforementioned components achieve the following effects: The ball bearings prevent the door from jamming on the connecting plate surface. When the door needs to be fixedly connected to the hinge, the bolts are unscrewed from the surface of the fixing post, and the door is fitted onto the surface of the fixing post. The conical block secures the fixing post inside the washing machine door, thus fixing the door in place. The bolts are then screwed into one end of the fixing post, further securing the door to the post surface. The pad prevents the door from contacting the bolts. The ball bearings and roller bearings prevent the door from jamming between the connecting plate and the fixing post surface, thus securing the door in place.

[0015] Preferably, the hinge surface is provided with an adjustment device, the adjustment device including a rectangular groove formed on the hinge surface, a bidirectional screw rotatably connected inside the rectangular groove, a slider threadedly connected to the surface of the bidirectional screw, and a connecting plate fixedly connected to one end of the slider.

[0016] The effect achieved by the above components is that, under the action of the bidirectional screw, the distance of the connecting plate can be adjusted, thereby facilitating the connection of the washing machine door and thus achieving the function of convenient connection.

[0017] Preferably, the hinge is threaded with a screw on its side, and one end of the screw abuts against the surface of the bidirectional screw.

[0018] The effect achieved by the above components is that, under the action of the screws, the position of the bidirectional screw rod can be fixed after the connecting plate is adjusted to a suitable position, thus preventing the connecting plate from shifting.

[0019] Preferably, a washer is fitted onto the surface of the screw, and the washer is a rubber ring.

[0020] The aforementioned components achieve the following effects: The washers prevent the screws from fully tightening the hinge's interior, thus avoiding hinge damage. When adjusting the connecting plate for easier installation, the screws are unscrewed to separate it from the double-acting screw. The double-acting screw is then manually rotated, causing the connecting plate to move under the action of the slider. Once in the desired position, the screws are tightened to the hinge's interior, pressing against the surface of the double-acting screw. Again, the washers prevent the screws from fully tightening the hinge's interior, thus avoiding hinge damage and achieving the function of adjusting the connecting plate.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a fixing device, when it is necessary to fix the door to the hinge, the bolt is unscrewed from the surface of the fixing post, and the door is fitted onto the surface of the fixing post. Under the action of the conical block, the fixing post can be fixed inside the washing machine door, thereby achieving the function of fixing the door. The bolt is screwed into one end of the fixing post, thereby fixing the door to the surface of the fixing post. Under the action of the pad, the door will not contact the bolt. Under the action of the ball and roller, the door will not jam between the surface of the connecting plate and the surface of the fixing post, thereby achieving the function of fixing the door. This solves the problem of inconvenient installation caused by the inability to limit the engagement of the hinge and the door during installation. Attached Figure Description
