This utility model belongs to the field of animal medicine, specifically a limb restraint for an animal examination table. It addresses the problem that existing simple strap designs, while capable of securing animal limbs, often lack adjustable strap lengths. Some restraints are also inflexible in design and use, with fixed positions that cannot be adjusted according to animal size and positioning. The proposed solution includes an examination table comprising a base, a worktable fixedly mounted on top of the base, and a reinforcing ring fixedly fitted onto the outer wall of the base; four restraints for securing the animal's limbs. Each restraint is located on one side of the worktable and includes a U-shaped frame and a rotating cylinder rotatably mounted inside the U-shaped frame. These restraints can be adjusted according to animal size, positioning, and limb orientation, greatly increasing adaptability and solving the problem of limited restraint mechanisms in existing examination tables, thus better meeting practical needs.

The invention relates to the field of motor control, in particular to a multi-motor compensation control method and device and a motor system. The method comprises the steps of determining a forward correlation motor and a reverse correlation motor of an abnormal motor if the abnormal motor exists every other preset time; respectively determining weight coefficients of the abnormal motor, the forward correlation motor and the reverse correlation motor; determining correction values of the abnormal motor, the forward correlation motor and the reverse correlation motor according to the deviation degree and the correction proportion of the abnormal motor so as to form a plurality of processing schemes; if the correction ratio is greater than 0, reducing the correction ratio to continuously form a plurality of processing schemes until the correction ratio is less than or equal to 0; each processing scheme is scored; and determining a final scheme according to the processing scheme with the highest score, and sending the correction values of the abnormal motor, the forward correlation motor and the reverse correlation motor of the final scheme to the corresponding motors so as to compensate the abnormal motor. The problem that the adjustment scheme is single is solved.

This invention relates to a low-temperature difference indirect temperature control multifunctional bathing aid device, comprising a bathtub and a bathing chair. On one hand, this invention indirectly adjusts the temperature of the bath liquid in the bathtub based on the temperature control of the water tank, and ensures that the water discharged from the bathtub can circulate and return while maintaining equal supply and return volumes. This not only eliminates safety risks caused by temperature differences in the bath liquid, but also avoids direct temperature control. Constant temperature control is achieved while the bath liquid is flowing, preventing direct waste discharge. Furthermore, based on the massage or acupoint stimulation function created by the water jets, and the equal supply and discharge of water in the water replenishment chamber, interference between inflow and outflow is avoided. The water replenishment chamber serves as the optimal water temperature monitoring area for more accurate temperature control. On the other hand, the built-in locking mechanism eliminates interference or obstacles caused by external components, preserving the overall aesthetic appearance of the bathtub. The locking force, generated by the internal squeezing force from multiple points on the lock head, not only allows for adjustment but also reduces safety risks associated with bathing.
