This invention discloses a push-pull retractable footrest and a seat. The push-pull retractable footrest includes a footrest, an outer telescopic component, an inner telescopic component, a connecting mechanism, a joint locking mechanism, and a position locking mechanism. The inner telescopic component is slidably connected to the outer telescopic component, and the linkage mechanism is rotatably connected to the footrest. The joint locking mechanism includes a locking head that locks or unlocks the footrest, and the position locking mechanism is locked at a first limiting part or a second limiting part. The seat includes a push-pull retractable footrest. In this invention, the linkage mechanism, joint locking mechanism, and position locking mechanism are linked together with the sliding of the inner telescopic component relative to the outer telescopic component, and perform corresponding unlocking, locking, and footrest rotation actions. When the footrest needs to be retracted, the user only needs to push or pull the inner telescopic component to switch the footrest's state. Furthermore, the footrest and the inner telescopic component can be locked after the footrest is retracted, keeping the footrest stable. The retraction and retraction actions are minimal, resulting in high operational convenience.

The utility model belongs to telescopic joint locking technical field discloses a kind of telescopic joint locking mechanism for petroleum steel pipe stability, including outer locking ring, connecting piece, locking inner tube and baffle, the accommodating space is formed in the inside of outer locking ring, the connecting piece and locking inner tube are set in the inside of outer locking ring, the locking inner tube is movably inserted in the inside of connecting piece, the outer locking ring is fixedly connected with the locking inner tube by fixed pin, the baffle is set in the inner end surface of outer locking ring, the baffle is fixedly connected with the connecting piece by screw.The utility model in the quick insertion of outer locking ring and locking inner tube by fixed pin is set, in combination with the screw fixing mode of baffle and connecting piece, the modular assembly of telescopic joint locking mechanism is realized, locking and unlocking can be completed by only inserting or pulling out fixed pin, without disassembling multiple fasteners one by one, avoid the delay of operation caused by operation time-consuming too long.

This invention relates to a lockable, variable stiffness linearly driven continuum robot, comprising a base, a linear guide propulsion module, coaxially fitted inner and outer tube continuum robot modules, and corresponding modules for driving, rotating, and locking the inner and outer tube continuum robot modules respectively. Both the inner and outer tube continuum robot modules consist of multiple joints connected in a serpentine structure via revolute joints, and include at least one locking joint. The locking module controls the rotation of the locking joint, causing its internal structure to engage a limiting block on the locking line, thereby fixing the length of the locking line from the base to the joint, achieving overall mechanical locking and stiffness enhancement of that segment of the robot's posture. This invention reduces the axial and radial dimensions at the joints, increases the range of robot stiffness variation and the robot's degrees of freedom, and adapts to internal surgical environments in confined spaces.

Embodiments herein relate to multi-part sill assemblies for fenestrations. In an embodiment, a multi-part sill assembly for a fenestration unit is included having an exterior sill subunit and an interior threshold subunit. The exterior sill subunit can be formed of a metal and the interior threshold subunit can be formed of a composite material. The interior threshold subunit can be joined to the exterior sill subunit by at least three different points of contact. The three different points of contact can include a pivoting joint; a locking joint; and an adhesive joint. Other embodiments are also included herein.
