6results about How to "Simple switch structure" patented technology

The utility model relates to the technical field of power switches and relates to a switch control device. Comprising a switch box, a switch key and a limiting assembly. The switch box is electrically connected with a lighting circuit on a control production line; the switch key is installed in an installation groove of the switch box, the two sides of the switch key are in shaft connection with the installation groove, and the switch key can swing in a reciprocating mode in the depth direction of the installation groove under the action of external force and control on-off of a lighting circuit on a production line in the swing process. The limiting assembly is installed in the switch box and used for limiting swing of the switch key in the installation groove. The switch not only can control the lighting circuit on the production line to be turned on by a specific magnetic card and avoid resource waste, but also is simple in structure and easy to use.

This invention relates to a water circuit switching structure and a toilet, characterized by comprising a water tank, a float, and a limiting block. The water tank has an inlet, a first outlet, and a second outlet. The float is movably positioned between the inlet, the first outlet, and the second outlet. The limiting block is located inside the water tank. When water enters through the inlet, the limiting block restricts the float to a first position, connecting the inlet to the first outlet. When water stops flowing through the inlet, the limiting block releases the float, and the float moves to a second position under buoyancy, resuming water supply to the inlet and maintaining the float in the second position, connecting the inlet to the second outlet. This invention has the following advantages: 1. It reduces reliance on a motor, reducing the occurrence of malfunctions. 2. The switching structure is simple, stable, and reliable, offering significant cost advantages. 3. It has a wide range of applications.

The utility model discloses a water outlet device, including flow channel subassembly, switch valve and casing, flow channel subassembly is located in the casing, switch valve is inserted with flow channel subassembly, and flow channel subassembly has water inlet flow channel, first water flow channel and second water flow channel, and switch valve is used for changing the communication relation of water inlet flow channel and first water flow channel and second water flow channel, and the circumferential side wall of casing is provided with the gap, water outlet device still includes water outlet control assembly, and water outlet control assembly sets up in the water outlet end of first water flow channel, and water outlet control assembly includes first water flow channel and second water flow channel, and part circumferential side wall of water outlet control assembly is exposed from the gap, when rotating or moving water outlet control assembly through the gap, first water flow channel is communicated with first water flow channel or second water flow channel. The utility model can satisfy the demand of different flow of user under different use scene, and can satisfy the demand of various water flower of user to water outlet device, and the water outlet function of water outlet device is enriched.

The invention relates to the technical field of medical auxiliary instruments, and discloses orthopedic knee joint rehabilitation auxiliary equipment which comprises rehabilitation chair supporting legs, a chair frame is mounted at the tops of the rehabilitation chair supporting legs, a sponge cushion is mounted at the top of the chair frame, a transverse rod is mounted at the bottom of the chair frame, and a rehabilitation training mechanism is mounted on the outer edge of the transverse rod. Through the arrangement of the passive telescopic cylinder and the active telescopic cylinder, the telescopic lead screw can drive the passive telescopic cylinder to stretch out and draw back in the active telescopic cylinder, so that the crus placing frame connected to the passive telescopic cylinder can be passively moved, and the patient lifts the crus to drive the crus placing frame and the active telescopic cylinder to move; the active telescopic cylinder moves to drive the first one-way valve and the second one-way valve to move, so that the patient can do active movement, and the problems that knee joint rehabilitation equipment is single in function, only a passive movement mode can be adopted from the initial stage to the final stage of rehabilitation of the patient, and an active training mode cannot be switched according to the rehabilitation stage of the patient are solved.

The application belongs to the technical field of robots, and discloses an amphibious robot propulsion device and method based on a wheel-propeller composite structure. The device is integrated with a reduction motor driving system of a wheel mechanism and a composite propeller system of a propeller mechanism, and outputs propulsion power in the same coaxial direction. The reduction motor driving system takes a waterproof reduction motor as a driver to provide power for the amphibious robot when walking on the ground. The composite propeller system takes a propeller as a driving component to provide power for the amphibious robot when floating in water. The application can interact with other structures to form vector propulsion, increase controllability and stability of the robot, and quickly switch between water and land modes. The switching structure is simple. Most amphibious robot water-land switching structures are too complex, which causes great pressure on the body space and reduces the practicability of the product.
