The sealing member includes a hard circular support plate, and a sealing portion integrally formed on a surface of the circular support plate by insert molding.

A limiting mechanism achieving rotary push-and-pull opening and closing on furniture comprises a furniture door body, a furniture cabinet body and at least two sliding rail assemblies. The at least two sliding rail assemblies at least comprise moving sliding rails and fixed sliding rails. Balls or rolling wheels are arranged between the moving sliding rails and the fixed sliding rails, and the moving sliding rails and the fixed sliding rails are in sliding fit through the balls or rolling wheels. The at least two moving sliding rails are arranged on the furniture door body, and the at least two fixed sliding rails are arranged on the side walls of the furniture cabinet body. Synchronous rods are arranged between the at least two moving sliding rails, and the at least two moving sliding rails synchronously slide on the at least two fixed sliding rails through the synchronous rods so that the furniture door body can be transversely and movably opened and / or closed to be stored on the furniture cabinet body. Transverse opening automatic locking devices are arranged between the side walls of the furniture cabinet body or between the fixed sliding rails and the moving sliding rails or between the synchronous rods. When the furniture door body is transversely and movably opened to a certain position relative to the furniture cabinet body, the movable opening position between the furniture door body and the furniture cabinet body is automatically locked through the transverse opening automatic locking devices, and practicality is high.

The invention discloses a sliding block of a sliding supporting hinge for a window. A protruding part is arranged in the middle of a sliding block body. The middle sections of the two side edges of the protruding part of the sliding block are stamped into middle parts which protrude upwards, and the height of the middle parts is matched with the height of the internal space of a sliding rail of the sliding supporting hinge. According to the sliding block of the sliding supporting hinge for the window, under the condition that the width and height of an existing sliding rail are not changed, improvement is conducted in cooperation with the internal space of the sliding rail, and the problem of an up-down gap between the sliding block and the sliding rail is well solved while the bearing capacity of the sliding block is guaranteed; the sliding block is high in structural stability, high in strength and good in abrasion resistance; and in addition, aging and deformation are avoided, and the service life of the sliding supporting hinge can be prolonged easily. In addition, the invention provides the sliding supporting hinge provided with the sliding block. The sliding supporting hinge provided with the sliding block has the high bearing capacity and can be used for opening and closing the window smoothly.

The invention can buffer the impact sound during opening and closing the washing machine cover and has a high production efficiency, which comprises a cover freely opened and closed on the washing machine top cover; an elbow joint spring applying force to the opening and closing direction of the cover; a buffer damper for buffering the rotation of the cover. The cover comprises a cover body and acover body lower frame installed from the lower portion. A cover spring, a spring axle supporting the cover spring, a buffer damper and a damper retainer which are integrated are arranged in a space portion formed after installation. Thus, the cover is prefabricated as a whole unit and installed on the top cover from the upper. The assembly procedure for the washing machine unit is diversified, thus improving the production efficiency of the washing machine cover.

The present invention provides a support device for a sliding door, which can be applied to various types of vehicles. A bracket (21) is provided which is fixed to the sliding door, and a first arm (23) is pivotally supported on the sliding door so as to be rotatable in the vertical direction through a first pivot shaft (22) parallel to the opening and closing direction of the sliding door. a bracket (21); a second arm (24), supported so as to be relatively movable in the left-right direction with respect to the first arm (23), and rotatable in the up-down direction integrally with the first arm (23); The guide pulley (25) is rotatable around a shaft (251) facing the up-down direction on the second arm (24) and can move along the guide rail.

The invention provides a washing machine cover structure which can eliminate the impact sound during opening and closing the washing machine cover and smoothly operate the opening and closing, comprising a cover freely opened and closed on the washing machine top cover; an elbow joint spring whose applying force to the opening and closing direction of the cover can be switched and a rotary bufferdamper for attenuating the cover rotation. The buffer damper is equipped in the buffer damper in a freely rotation and sliding way. The damper is kept in a free rotation range provided with a preset angle in the rotation direction between the damper retainer and the buffer damper. At the initial stage of opening and closing of the cover, the attenuation of the buffer damper does not act on the cover rotation owing to the free rotation range. Thus, the user can open and close only with a force against the load such as the elbow joint spring and the cover dead weight in the initial stage. The opening and closing operation is convenient.
