A pipe joint structure includes a plurality of fluid flow path portions, a socket connected to the fluid flow path portions, a connection plate disposed to abut against the socket, a plurality of pipes connected to each other by the connection plate, and a seal member disposed between the plurality of pipes and the socket. The socket includes a connection portion that is located to cover an edge of the connection plate and to fix the plurality of pipes to the plurality of fluid flow path portions. The pipe joint structure can be suitably used for a heat exchanger.

A USB connector structure, configured with a combination structure of a base, a main structure, a plural of pins and a fixing structure, to enable said plural pins to be configured on the conducting pads without soldering process and to provide a convenient assembly by firmly hooking and fastening both the main structure and the fixing structure over the base. And, the present invention can be applied in various USB connectors or similar connecting structure.

The invention discloses a muscle driving simulation robot joint, which belongs to the technical field of the biomimetic robot joint. The invention particularly relates to the muscle driving simulation robot joint which consists of a double-crank sliding block mechanism and is similar to the human muscle confrontation driving characteristic. The muscle driving simulation robot joint has the advantages of flexible action, big working space and simple structure and can be used for simulating the human muscle rigidity nonlinear driving. The muscle driving simulation robot joint comprises a rear crank sliding block mechanism, a front crank sliding block mechanism and a fixed pulley, wherein the rear crank sliding block mechanism and the front crank sliding block mechanism are respectively provided with a fixedly-connected linear guide rail for a rack; the fixedly-connected linear guide rail for the rack is provided with a sliding block; the sliding block is connected with one end of a connecting rod; the rotating center of the rack is provided with the first end of a fixed shaft rotating crank; the other end of the connecting rod is connected with the tail end of the fixed shaft rotating crank; the rotating center of the fixed pulley is provided with the fixed pulley; the fixed pulley is provided with a soft rope; and two ends of the soft rope are respectively connected with the junction of a rear fixed shaft rotating crank and a rear connecting rod as well as the junction of a front fixed shaft rotating crank and a front connecting rod.

The invention discloses a structure of rope-driven mechanical arm rotation joint. The structure comprises a synchronous belt wheel shaft, a synchronous belt, an angle sensor, an arm joint bearing end plate, a deep groove ball bearing, an angular contact ball bearing and a mechanical arm connection clamping block, wherein the mechanical arm connection clamping block is provided with a connection hole and a steel wire rope through hole; the synchronous belt wheel shaft comprises a belt wheel end and a shaft end from top to bottom; a sensor containing hole, a sensor output shaft connection hole and a cross recessed countersunk head screw inner threaded hole are arranged along the axis of the synchronous belt wheel shaft in sequence; and the inner rings of the deep groove ball bearing and the angular contact ball bearing are respectively fixed at the upper part and the lower part of the belt wheel end through transition fit. According to the structure, the movement of the joint in a relatively large range can be realized; by adopting a detachable structure, the maintenance and carrying are convenient, the structure is simplified, the running efficiency of the joint is improved and the movement coupling of the joint is avoided; the problem that only stretching can be carried out and compression cannot be carried out in the rope driving process, the structure is simple, and stroke range is large, so that the structure is particularly suitable for being installed on the disabled and aged helping facilities such as wheelchairs and care beds.

The invention relates to a porous ceramic connecting method, relates to a ceramic connecting method, and aims to solve the problem that the process is complex when wettability is improved and thermal stress is relieved simultaneously when conventional porous ceramic is connected with metals. The porous ceramic connecting method comprises the following steps: I, preparing an organic phenolic resin solution; II, performing thermal treatment on porous ceramic; and III, connecting the porous ceramic. Due to a surface layer pore structure of the porous structure, a brazing filler metal can permeate into a base body to form a connecting structure with mechanical occlusion and chemical bond combination, not only is residual thermal stress of a connector effectively relieved, but also a boundary reaction combination area is increased, and the strength of the connector can be improved. The porous ceramic connecting method is applied to the field of connection of ceramic and metal materials.
