  • Publication number: 20210114426
    Abstract: A suspension arm includes a ball stud including a spherical ball; a bearing in which the ball is accommodated; a housing having an inner peripheral portion, an outer peripheral portion, and a lower end portion that connects a lower end of the inner peripheral portion and a lower end of the outer peripheral portion, and configured to accommodate the ball and the bearing in a state in which the ball and the bearing are spaced apart from the inner peripheral portion; an arm body coupled to a portion of the outer peripheral portion of the housing; and an insert molding part formed on an outer peripheral portion of the bearing, the inner peripheral portion of the housing, and the lower end portion of the housing to couple the bearing with the housing. A convex-concave portion is formed on the inner peripheral portion of the housing along a circumferential direction.

  • Publication number: 20210114427
    Abstract: A suspension arm includes a ball stud including a spherical ball; a bearing in which the spherical ball is accommodated; a housing having an inner peripheral portion and an outer peripheral portion; an arm body coupled to the outer peripheral portion of the housing; and an insert molding part which is injected to a lower portion of the bearing and the outer peripheral portion of the housing to be coupled to the bearing, the housing, and the arm body. The housing includes a matching portion having a matching surface formed to protrude in a radially outward direction from an upper portion of the outer peripheral portion and to be brought into contact with a mold. By forming the matching portion, it is possible to reduce the volume of the housing and to reduce the weight of the suspension arm while providing the matching surface with the mold.

  • Publication number: 20130075058
    Abstract: A cooling cabinet includes a cabinet and a heat exchange member and an air ventilation member are received therein. A first pipe group and a second pipe group are located in the heat exchange member and each of the first and second pipe groups includes multiple parallel circulation pipes. Two respective first ends of the first pipe group and the second pipe group are in communication with each other, and two respective second ends of the first and second pipe groups are respectively in communication with a refrigerant inlet and a refrigerant outlet. The refrigerant flows through the first pipe group via the refrigerant inlet and then flows through the second pipe group and exits from the refrigerant outlet. The air ventilation member is located beside the heat exchange member and ventilates the air inside and outside of the cabinet via the heat exchange member.

  • Publication number: 20110115345
    Abstract: An extendable instrument cabinet includes a rectangular framework and an extension frame assembly. By the extension frame assembly connected to the rectangular framework, the instrument cabinet can enhance its capacity. The extension frame assembly includes an end frame and a side frame. The rectangular framework can be selectively mounted with the end frame or the side frame, as desired. Besides, the rectangular framework can be mounted with more than one end frame or more than one side frame in conjunction with fasteners, through holes, end frame through holes, and side frame through holes. Furthermore, each of the end frame and the side frame has a bottom provided with a foot structure for supporting its weight.
