The present invention provides an original manuscript pressing plate opening and closing device and office equipment with an original manuscript clamp plate, wherein the original manuscript pressing plate opening and closing device is configured for comprising the following components: an installing component which is provided with a base plate that is installed on the device body side of office equipment with an original manuscript clamp plate, and two side plates which is projected from two side parts of the base plate; and a supporting component which is provided with a roof plate and two side plates which droop downwards from the two side parts of roof plate. The supporting component installs two side plates on two side plates of installing component and supports the original manuscript pressing plate with a mode that two side plates can be rotated through a hinge pin. The installing component is installed on the device body with a detachable mode through inserting and clamping an installing buckle which is installed on the device body into a clamping hole that is set on the base plate of installing component. The original manuscript pressing plate is provided with a loosening preventing component which is configured that an adjusting plate is installed on the installing component with a mode that the adjusting plate slides through the adjusting screw and the end part of the adjusting plate can be pressed into the part between the base plate and the installing buckle.

The invention provides a ring-type stapling device which comprises: a base part (2) with shell shape; plural rings (3) set on the base part, changing ring-closure posture and ring-opening posture by contacting or getting far away of the free ends of one side-ring and the other side ring; a first supporting component (4) for supporting one side ring and a second supporting component (5) for supporting the other side ring, which are installed in the base part; an operation component (6) which can move forth and back along the length of the base; a switching structure set among the first supporting component, the second supporting component and the operation component, which makes the first and the second supporting components lean around the base part when the operation component moving back and forth so that the ring can switch postures between ring-closure and ring-opening.

A cap for a cosmetic case is provided. The cap includes a cap body and a sealing member. The cap body is made of a hard material and includes an upper wall, a sidewall extending downwards from an edge of the upper wall, a threaded portion formed on an inner circumference of the sidewall, and a fitting space defined by an inner border surface between the upper wall and the sidewall. The sealing member is press-fitted into the fitting space of the cap body, and exerts or releases a sealing force on or from the mouth of the cosmetic case when the cap body is opened or closed relative to the mouth of the cosmetic case in the threaded fastening method. 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 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 an original manuscript pressing plate opening and closing device and office equipment with an original manuscript clamp plate, wherein the original manuscript pressing plate opening and closing device is configured for comprising the following components: an installing component which is provided with a base plate that is installed on the device body side of office equipment with an original manuscript clamp plate, and two side plates which is projected from two side parts of the base plate; and a supporting component which is provided with a roof plate and two side plates which droop downwards from the two side parts of roof plate. The supporting component installs two side plates on two side plates of installing component and supports the original manuscript pressing plate with a mode that two side plates can be rotated through a hinge pin. The installing component is installed on the device body with a detachable mode through inserting and clamping aninstalling buckle which is installed on the device body into a clamping hole that is set on the base plate of installing component. The original manuscript pressing plate is provided with a looseningpreventing component which is configured that an adjusting plate is installed on the installing component with a mode that the adjusting plate slides through the adjusting screw and the end part of the adjusting plate can be pressed into the part between the base plate and the installing buckle.
