A reciprocator-typed quick-releasing mechanism includes a base, a latching component and an actuating component. The base is disposed inside a first module, and has a first piercing hole and a first opening. The latching component is disposed on the base, and includes a constraining portion and a resilient portion. The constraining portion aligns with the first piercing hole and a second piercing hole on a second module. The resilient portion is connected to the constraining portion. The actuating component is slidably disposed on the base and includes a pushing portion and an actuating portion. The actuating portion is connected to the pushing portion and protrudes from the first opening and a second opening on the second module. The actuating portion moves relative to the second opening to flexibly deform the resilient portion via the pushing portion, so as to remove the constraining portion from the second piercing hole.

A safety pin locking device for workpiece turnover includes a safety pin, a triangular lock plate, an elastic positioning pin, and a lockset. The safety pin is configured to be inserted into a base and an overturnable workpiece to lock an angle of the overturnable workpiece relative to the base. A first corner end of the triangular lock plate is connected to an axial surface of the safety pin by a fastener, and the triangular lock plate can rotate around the fastener. The elastic positioning pin is mounted at a second corner end of the triangular lock plate and is configured to be inserted into positioning counterbores at two different positions on the axial surface of the safety pin to limit a position of the triangular lock plate. The lockset is mounted at a third corner end of the triangular lock plate.

A hold open rod is configured to provide switched damping movement includes an inner tube assembly coupled to an outer tube assembly, the inner tube assembly movable within the outer tube assembly. The hold open rod also includes a damping mechanism configured to damp movement of the outer tube assembly with respect to the inner tube assembly.

A locking assembly and a socket configured with the locking assembly, wherein the locking assembly is for axially locking a ferrule in a socket. The locking assembly has a block that is able to be positioned and secured in the socket adjacent to the opposing end of the ferrule. The locking block may be a drop-in locking block with a major face that abuts an end of the ferrule to secure it in the socket. The locking block may also have one of a trapezoidal prism, an elongate cam element, or transversely sliding block parts, each of which can abut an end of the ferrule to secure it in the socket.

This invention is related to a service brake chamber manufactured with a composite pressure housing and a non-pressure housing, used in the air brake system of heavy vehicles such as trucks, trailers lorries and buses and a connection method of pressure housing and non-pressure housing forms this chamber.

A fluid-actuated fastening device comprises a housing including a housing body defining a fluid cavity and a fluid port. The fluid port places the fluid cavity in selective communication with an outside fluid source. A telescoping mast assembly includes a mast sleeve. A spindle has longitudinally spaced inner and outer spindle ends separated by a longitudinally oriented spindle body. The spindle body is at least partially located within the mast sleeve for telescoping longitudinal movement with respect thereto to transform the mast assembly between compressed and expanded mast states. At least one disc spring is located substantially within the fluid cavity. Introduction of pressurized fluid into the fluid cavity via the fluid port causes at least one of travel of the disc spring between flexed and relaxed spring states and translational movement of the mast between the compressed and expanded mast states.

A first member having a first lock groove and a second member having a connection hole for insertion of the first member and a second lock groove opened to an inner periphery of the hole, are connected via a lock ring having a circular section and engaging with the grooves. An outer diameter of the ring under a load-free condition is set not less than a diameter of a groove bottom surface of the second lock groove. A reduced-diameter guide hole portion for guiding the ring to the second lock groove while reducing a diameter of the ring, is adjacently disposed short of the second lock groove in an insertion direction of the first member. A depth from an inner peripheral surface of the guide hole portion to a groove bottom surface of the second lock groove is set less than a radius of the circular section of the ring.
