The invention relates to a linked-control electric reclining wheelchair. The front end and the rear end of a base are connected with leg guard racks and a back frame respectively through rotary shafts. The back frame is connected with the leg guard racks through an armrest connecting bar mechanism movably connected to the base. A frame beam of the back frame is connected with a lower fixed beam at the rear end of the base through a linear motor controlled through a control mechanism. When the linear motor retracts, the back frame rotates down around the rotary shaft of the base, and the armrest connecting rod mechanism drives the leg guard racks to rotate up around the rotary shaft of the base. For a patient user, the linked-control electric reclining wheelchair can be controlled by the user for lying down, and accordingly psychological rehabilitation and confidence rebuilding are emphasized, and humane care is embodied. In addition, bedsore can be prevented, hip pressure is relieved, and proper lying can reduce spinal pressure in long-term sitting. Technically, simultaneous control of a back and a leg guard board by a single motor is achieved, mechanism complexity is reduced greatly, cost is reduced, and power is economized.

The invention discloses a novel flexible four-jaw chuck comprising a chuck body, a scroll, four small bevel gears engaged with the scroll, four linked jaws which are driven through the scroll and which are distributed and arranged on the chuck body within 90 DEG included angles, four steering blocks arranged on the linked jaws, four screws and four sliding jaws. The sliding jaws match with the screws which are located in arc grooves of the steering blocks, and stop rings fixed on the steering blocks limit the screws to move upwardly and axially. The novel flexible four-jaw chuck comprises four worms, four worm gears provided with through holes, and four T-shaped countersunk head rods. Thus, all functions of an existing flexible four-jaw chuck are provided to the novel flexible four-jaw chuck, the linkage function can be implemented optionally, and the steering block 1 can steer at optional degrees, so that effective clamping of different irregular workpieces is realized actually, efficiency of mounting and demounting workpieces is improved greatly through the linkage function, and production efficiency and practicality are improved.

The invention discloses a button switch. The button switch comprises a shell and a plurality of buttons, wherein the buttons are arranged on the shell. Button springs are arranged between the shell and the buttons, so that the buttons has the trends to move away from the shell in the vertical direction. The button switch is characterized in that a linkage plate is arranged on the shell, one end of the linkage plate is connected with an elastic part, so that the linkage plate has the trend to move away from the elastic part all the time, a clamping hook is arranged on each button, and a plurality of clamping buckles corresponding to the clamping hooks are arranged on the lateral side of the linkage plate. If any one unlocked button is pressed, the corresponding clamping hook drives the linkage plate and all the clamping buckles to move towards the elastic part along with the descending process of the button, so that the clamping hook completes the buckling action, and meanwhile, other buckled and locked buttons are unlocked. By means of the button switch, the linkage function of the buttons is achieved, the interlocking function of the buttons is achieved through interlocking blocks and liming blocks, and the situation that the buttons are pressed at the same time, so that a plurality of switches are turned on or off at the same time is prevented, wherein the limiting blocks are arranged on the outer surfaces of buttons respectively. The button switch is simple and reliable in structure and convenient to use.

The invention discloses a liquid transmission mechanism and a shower room provided with the same. The liquid transmission mechanism comprises a liquid pipe, a magnetic piston unit and a magnetic connector, wherein a returning pipeline is formed in the liquid pipe, and the magnetic piston unit can be arranged in the returning pipeline; the magnetic connector is externally arranged on the outer wall of the liquid pipe and is matched with the magnetic piston unit in a manner of magnetic attraction, wherein the magnetic connector is driven to move and the magnetic piston unit matched with the magnetic piston unit in a manner of magnetic attraction is linked to displace in the liquid pipe. The liquid transmission mechanism and the shower room provided with the same, disclosed by the invention, have the advantages that the structure is simple, the design is reasonable and the implementation is easy; the liquid transmission mechanism is applicable to multiple room types, is not limited by the shape of the room, and has the beneficial effects that synchronous opening and closing of arc-shaped shower rooms and special shower rooms can be realized, the product structure is simplified, the parts are reduced, the cost is low, the maintenance and the adjustment are convenient, the appearance is exquisite, and the needs for low cost and easy installation and adjustment are easily met.

A passive space lock release device, comprising a shell, a lock hook assembly, a sliding pin, a pressure plate, an operating rod, an end cover, a strap assembly, a bottom cover, and a tension spring assembly; a set of locks is installed in a groove outside the shell Hook assembly; one end of the lock hook of the lock hook assembly is provided with a waist-shaped hole, and a sliding pin is installed in the waist-shaped hole, and each pressure plate slides in the pressure plate sliding groove to form a pin movement pair; the end cover is fixedly installed at the port of the cylinder part , each pressure plate is connected with the end cover through the tension spring assembly; a number of operating rods are evenly distributed on the strapping assembly along the circumferential direction; the strapping assembly is sleeved outside the lock hook assembly, and the strapping structure is provided with explosive bolts, which are unlocked by the explosive bolts; The bottom cover is installed on the casing to cover the strap assembly and the lock hook assembly. The side wall of the bottom cover is provided with an operating rod movable groove along the longitudinal direction, and the operating rod protrudes from the operating rod movable groove. The present invention can realize the functions of manual locking and releasing and automatic releasing of pyrotechnics, and in cooperation with the locked piece, the present invention has the functions of electric unlocking and releasing.
