The utility model discloses a dynamic muscle nature's neck rehabilitation training brace relates to medical rehabilitation instrument technical field, and the utility model discloses a cape, and the both sides of cape outer surface and the both sides of back are all provided with servo motor and take off and put on the roll, and four servo motor output all are connected with worm, and four take off and put on the back of roll all are connected with worm wheel, and the top of cape is connected with head hoop through a plurality of ball head seat. The utility model discloses the setting of servo motor, worm, worm wheel, take off and put on the roll and first pull rope, and four servo motor outputs are driven four take off and put on the roll rotation respectively through four worms and four worm wheel meshing, thereby being convenient for to take off or put out to first pull rope, second pull rope, third pull rope and fourth pull rope, when first pull rope and second pull rope take off and third pull rope and fourth pull rope put out, make the head of patient to the right side of self inclination, do not need medical staff or family member manual traction patient head and make neck movement, and the operation is time -saving and labor -saving.

This utility model relates to the technical field of tape traction equipment, specifically a tape feeding and traction device. The device includes a support frame with an open side. Inside the support frame is a vertically movable clamping plate used to press the end of the tape into the support frame. A control slot is provided at the top of the support frame, and a drive plate is fixedly connected to one side of the clamping plate. This utility model uses the clamping plate and support frame to fix the end of the tape. The movement of the support frame drives the tape end to move, allowing the traction rollers that guide the tape to separate in a smaller space. This allows the clamping plate and the tape end to pass between two close traction rollers, facilitating traction operations within the limited space of the equipment. Furthermore, because the entire end of the tape is fixed, the tape remains spread out during traction, preventing folding during manual traction.

The utility model discloses a traction device for a mine car to enter a tank automatically, which relates to the technical field of mine transportation equipment and comprises tracks and a mine car, a fixing frame is arranged between the two tracks, two ends of the inner wall of the fixing frame are respectively provided with two rotating rods in a rotating mode through bearings, and two ends of each rotating rod are respectively and fixedly provided with a chain wheel. Chains are connected between the two chain wheels of the two rotating rods, a connecting rod is fixed between the two chains, a push plate is fixed at the upper end of the connecting rod, a stress plate is fixed at the lower end of the mine car, anti-falling structures matched with each other are arranged on the push plate and the stress plate, an oiling mechanism is arranged at one end of each chain, and one rotating rod is connected with a driving assembly. The anti-disengaging structure comprises a first clamping block fixed to one side of the push plate, a second clamping block is arranged on one side of the stress plate, and the first clamping block is located above the second clamping block. According to the utility model, manual traction is not needed, the positioning is accurate in the traction process, the device is not easy to fall off from the mine car, and the problem of poor efficiency is solved.
