Abstract: The present invention relates to a valve with a hinged valve core. The valve comprises a valve body, a valve core, an operating mechanism, a motion-transferring device and a locking device. The valve body is a housing. The housing is formed with a operating hole used to partially accommodate the operating mechanism and a channel having an inlet and an outlet. The valve core is connected with the valve body through a hinge. The operating mechanism is used to operate the valve core to be rotated around the central axis of the hinge to open/close the valve. The motion-transferring device is used to transfer actions on the operating mechanism to the valve core, and when the valve is closed or open, the valve core is locked on the valve body through the locking device. The valve of the present invention has a compact structure, is easy to operate, requires a small torque for opening and allows a large flow when opened.

Abstract: A hinge fixing structure used to hold a hidden hinge on a container, and a hidden hinge and a container. The hidden hinge comprises an upper hinge base, a hinge body and a lower hinge base. The container comprises a side plate and a door, which are respectively provided with grooves formed by the internal and external sidewalls thereof and used to accommodate hinge bases. The hinge fixing structure comprises position limiting structures located in grooves and used to prevent the hinge bases from releasing from the mouth portions of grooves and positioning structures provided on the upper hinge base and the lower hinge base and engaged with the limiting structures respectively. The position limiting structures are engaged with the positioning structures respectively so that the hidden hinge is held on the container, and the hidden hinge is completely invisible from the appearance of container when the door is closed.

Abstract: A lid locking mechanism of a container is disclosed herein. the container includes a base, side plates and a lid. The locking mechanism is provided on an edge of the lid and an upper portion of the side plate; and the locking mechanism comprises a locking structure, a restoring structure and a guiding structure; wherein the locking structure is used to lock the lid to the side plates of the container, and the restoring structure and the guiding structure are used to assist the locking structure in locking the lid to the side plates. The locking mechanism of the present invention will not be damaged easily, and it is very convenient to open and close the lid provided with the locking mechanism.

Abstract: This invention discloses a collapsible container, comprising a base and two pairs of opposite side walls. The side walls are provided with one or more movable portions extending from the bottom of the side walls. The base is provided with one or more opening pockets, wherein the side walls are disposed in the corresponding opening pockets on the base via the movable portions. A hinge device is provided between the movable portions and the opening pockets. The hinge device comprises: hinge holes provided in the movable portions of the side walls; a guiding device provided in the opening pockets of the base; and a connecter provided with hinge pins and a sliding device to be engaged with the guiding device. The sliding device of the connecter is movable up and down in vertical direction along the guiding device in the opening pockets. The hinge pins are disposed in the hinge holes and are rotable around the hinge pins.

Abstract: A hinge system comprises a first component and a second component. Arranged on the first component, a first pin (314) and a second pin (324) are not on a same axis. The first pin is movably arranged in a first slot (814) on the second component. The second pin is movably arranged in a second slot (824) on the second component. The first component selectively stays in a first position state or a second position state relative to the second component, thus allowing the hinge system to be folded reliably and conveniently. Also a collapsible container comprising the hinge system is disclosed.

Abstract: A locking system applicable in a large container comprises a first component, a second component, and a latch (10). The latch (10) is movably received within the first component, and correspondingly the second component is provided with a groove (14) to receive a section of the latch (10) extending from the receiving section of the first component. The locking system also comprises a handle (9). The handle (9) is arranged on the first component via pivot shafts (13) and is allowed to turn towards an outer side of the first component. The handle (9) is provided at a section thereof away from the pivot shaft (13) with male pins (11). The latch (10) is provided with concave profiles in correspondence to the male pin (11). The male pin (11) and the concave profile (12) are engaged to form a sliding pair. Furthermore, the handle (9) and the latch (10) constitute a lever system.

Abstract: A valve and valve cartridge assembly can provide an opening and closing operation with a low torque. The valve and valve cartridge assembly can be switched between a first transmission relationship and a second transmission relationship, and the first and second transmission relationships are formed between the top of the valve cartridge and a transmission device. The first transmission relationship is established so that the valve cartridge is driven to rotate axially. The second transmission relationship is established so that the transmission member drives the valve cartridge to carry out a squeeze sealing movement.

Abstract: A valve core assembly and a valve adopting the valve core assembly. The valve core assembly comprises a valve core (4) and a transmission member (7) having a common axis, and a sliding ejector pin (6) arranged along an axis perpendicular to the common axis. The valve core assembly is disposed inside a valve body (1) and is rotatable about the common axis upon engaging with the valve body (1). The valve core (4) has one concave portion, and the transmission member (7) is at least partially placed inside the concave portion.
