The utility model provides a closestool guardrail capable of preventing a patient from falling down, which relates to the field of medical instruments and comprises an alarm device and a blocking mechanism. The blocking mechanism comprises a blocking piece which is arranged on the front side of the closestool and used for blocking a falling-down patient; and the trigger is used for starting the alarm device to give an alarm. Through the protection mechanism, the protection mechanism comprises the alarm device and the blocking mechanism, when the patient defecates forcibly and faint and falls down forwards due to insufficient blood supply, the patient about to fall down is blocked by the blocking piece, the patient is prevented from being injured due to faint and falling down during defecation, and meanwhile the alarm device is triggered through the trigger to give an alarm; and medical personnel in a ward and a nurse station are timely informed to carry out assistance.

The utility model belongs to the technical field of subway pedals, and provides a subway vehicle-mounted platform clearance compensation pedal which comprises a base and a lingual plate, at least two T-shaped guide rails are symmetrically arranged on the base, at least two T-shaped sliding grooves are symmetrically formed in the lingual plate, the two T-shaped guide rails are connected into the two T-shaped sliding grooves in a sliding mode respectively, and the lingual plate is connected with the base. The bases and the tongue plates are uniformly distributed in the horizontal direction, an upper cover plate is arranged on the bases, a plurality of first screw holes are formed in the side edge of the upper cover plate, and a driving assembly is arranged on each base; the electric push rod of the driving assembly drives the tongue plate to automatically stretch out and retract through the connecting component, the gap between the subway door and the platform is effectively compensated, passengers can conveniently get on and off the subway, and the passengers carrying luggage, pushing baby carriages or having difficulty in moving are not prone to being stumbled by the gap and prevented from falling down and being injured. And feet of passengers or luggage are prevented from being clamped between the bus door and the platform, and the phenomenon that the luggage is clamped or damaged is avoided.

This utility model discloses a double-pulley device for a stair climber, relating to the field of fitness equipment and applied to a stair climber. It includes a dual-pulley resistance source with a first drive wheel and a second drive wheel; a first pulley assembly including a first pulley and a first belt, the first belt coupling the first drive wheel to a drive shaft; and a second pulley assembly including a second pulley and a second belt, the second belt coupling the second drive wheel to a drive shaft. The first pulley assembly is configured for high-friction transmission; the second pulley assembly is configured for low-friction transmission, with its friction being less than that of the first pulley assembly. This allows it to provide a buffering damping force to the drive shaft by slipping when the first belt fails. During normal operation, the device operates automatically. However, when the first belt slips off or fails, the friction between the second pulley and the second belt provides sufficient damping force to slow the descent of the stair treads, thus providing a buffering and protective function.

The utility model relates to nursing bed technical field discloses a multifunctional nursing bed for hospital urology department, including urination mechanism, protection mechanism and bed body mechanism, the urination mechanism is located inside bed body mechanism, the protection mechanism is located at the upper end of bed body mechanism. The urination mechanism includes the mounting bracket, the inner wall rotation of mounting bracket is connected with the flap, the inner wall sliding of mounting bracket is connected with the urine storage box, the left end of urine storage box is equipped with the limit slot, the inner wall of limit slot is connected with the limit frame, the lower fixed connection of limit frame has the connecting plate, the surface sliding of limit frame is connected with the protection shell. The utility model discloses the design that the limit frame is moved with spring drive limit frame to rebound through using the connecting plate to pull, has realized the purpose that the urine storage box is positioned and removed conveniently, make the staff when replacing urine storage box more convenient and fast, has improved the practicality of device whole.
