This application relates to an anti-slip and anti-collision pusher for a cartoning machine. The pusher body is detachably mounted on the output end of the pusher arm of the cartoning machine. Symmetrical material trough guides are provided on the outer walls of both sides of the pusher body along the pushing direction. The pusher body reciprocates within the material trough via the material trough guides, pushing the product to be packaged into the packaging box through the material pushing surface. A limiting block protruding from the material pushing surface is also provided at the outer end of the material trough guides. An anti-collision ramp is also provided on the top of the pusher body, located above the material pushing surface. The anti-collision ramp is inclined away from the pushing direction of the pusher body and is connected to the material pushing surface. The pusher body guides the product to be packaged smoothly into the packaging box through the anti-collision ramp. This application can accurately limit the lateral displacement of the product strip through the lateral constraint of the limiting block, preventing it from sliding into the angle area between the pusher body and the packaging box and being squeezed and damaged. This design improves the working efficiency and packaging effect of the entire packaging production line.

This utility model relates to the field of obstacle training equipment technology, and discloses a training device for motor disorders based on neurology, including a training device body, a handle, two foot pedals, and two foot pedals. The training device body has an internal mounting cavity, and an air supply mechanism is connected inside the mounting cavity. The output end of the air supply mechanism is connected to the two foot pedals respectively. Each foot pedal has an internal air passage, and several air outlets are formed at the end of each air passage away from the training device body. A control component is connected to the external side of the two foot pedals near the air outlets. This training device for motor disorders based on neurology inflates the foot straps through the air supply mechanism, causing them to automatically conform to the patient's instep and form a flexible clamp. A second pressure sensor monitors the contact pressure in real time, ensuring moderate and reliable fixation. Compared with traditional anti-slip rings, this effectively solves the problem of foot slippage caused by weak lower limb strength, ensuring training continuity and rehabilitation effects.

The utility model relates to the technical field of massage beds, and discloses a sheltering structure and a bed body, the sheltering structure comprises a sheltering body, a sheltering cover, a first rotating disc, a sliding connecting rod and second rotating discs, the sheltering cover is located above the sheltering body and is rotatably connected with the sheltering body, and the first rotating disc and the second rotating discs are rotatably installed on the sheltering body; the first turntable is connected with the second turntable through a sliding connecting rod, a triggering part for triggering the first turntable to rotate is arranged on the first turntable, and the first turntable and the second turntable are used for opening or closing the shielding cover. A triggering part is arranged on the first turntable, the first turntable is connected with the second turntable through a sliding connecting rod, and when the first turntable is triggered to rotate, the second turntable is driven to rotate through the sliding connecting rod, so that the shielding cover is closed, foreign matters are prevented from entering the opened bed body to influence normal use of the bed body, and the use safety of the bed body is ensured. When the bed body is closed, the shielding cover is opened, interference between the shielding cover and other parts of the bed body is avoided, and normal closing of the bed head is guaranteed.
