According to the automatic take-up and pay-off device, the structure is simple, the convenient and practical effects are achieved, and the motors are adopted to drive the winding roll to rotate in positive and negative directions so as to realize automatic take-up and pay-off; and rotating of the screw rod is utilized to drive the height adjustable bracket and the guiding wheels to conduct reciprocating movement so as to realize automatic winding displacement, and even cable winding is ensured.

The invention discloses a looping and unwinding device. The looping and unwinding device comprises a first bracket platform tension frame, a dragging machine, a controller and an unwinding part, wherein the tension frame, the dragging machine and the controller are separately arranged at the upper part of a first bracket platform; a screw rod, a movable platform and the unwinding part are separately arranged at the lower part of the first bracket platform; the tension frame is used for placing to-be-unwound workpieces output by an extrusion device; the dragging machine is used for dragging the to-be-unwound workpieces from the tension frame to the unwinding part; the controller is separately connected with the tension frame, the dragging machine and the unwinding part and is used for controlling the looping and unwinding device to run and controlling the unwinding part to rotate. Through the looping and unwinding device, the workpieces can be automatically wound, looped and unwound; especially, the problems such as deformation and bending and the like which are easily caused in the winding and unwinding process when the workpieces are semi-hard or soft tubes can be solved; the rejection rate is greatly reduced; and the winding and unwinding quality is improved.

The invention relates to the technical field of water leakage detection, in particular to a water leakage detection line and a water leakage detection system applying the same. The water leakage detection line comprises a cable skeleton; a conductive induction line; an insulating protection layer, wrapping the cable framework and the conductive induction lines, and water permeable holes being formed in the insulating protection layer; a first ribbon, one end of the first ribbon being arranged on the insulating protective layer, and the other end being provided with a first locking part; and asecond ribbon, arranged on the insulating protective layer, can be matched with the first ribbon to surround the pipeline to be detected, and being provided with a second locking part matched with thefirst locking part. The cable skeleton and the conductive induction lines are wrapped by the insulation protection layer. The situation that the conductive induction line falls off from the cable framework and is short-circuited is avoided. The false alarm probability is reduced, the water leakage detection line is fixed in a mechanical locking mode, and the situation that the water leakage detection line falls off from the to-be-detected pipeline and cannot detect a water leakage signal is avoided.

The invention discloses a winding and unwinding method of a monitoring cable of a monitoring device. According to the unwinding process, the monitoring cable of the monitoring device is pulled out downward or obliquely downward; and according to the winding process, a winding device is started, and the monitoring cable is disposed in a wire storage box used for storing monitoring cable and locatedbehind the winding device. According to the winding and unwinding method of the monitoring cable of the monitoring device, winding and unwinding are facilitated, automatic winding is achieved, and the monitoring cable can be effectively prevented from being damaged. According to the unwinding process, the monitoring cable of the monitoring device is only pulled out downward or obliquely downward.

The invention relates to a wire take-up control box. The take-up control box includes a box body, a circuit board and a turntable for winding cables. The turntable is provided with a turntable conductive transfer structure for external cables, and the box body is provided with a box body that is electrically connected to the circuit board and the turntable conductive transfer structure. Conductive transfer structure, there is also a take-up elastic part in the box body, which is used to deform when the turntable rotates in the forward direction to store the potential energy, and releases the potential energy to rotate the take-up when the turntable is turned in the reverse direction. Locking mechanism that locks the turntable and / or cable when the line is in place, and unlocks when the line is taken up. The wire take-up control box of the present invention can drive the turntable to reversely rotate and automatically take up the wire through the potential energy in the take-up elastic member, and the cable for automatic take-up is wound on the turntable, which does not occupy the space outside the box and can shorten the take-up time. Save labor and improve customer satisfaction.

The invention relates to a treadmill exercise testing machine suitable for first aid and a use method thereof. The top support armrest is a non-slip rod structure made of wood structure, An automatictake-up and take-up device is arranged in the middle position of the top supporting armrest, A lead wire and an output wire of an electronic blood pressure meter are arranged in the lead wire; an electrocardiograph is connected at the bottom of the lead wire; an output wire of the electrocardiograph is arranged at the bottom of the electrocardiograph; and the output wire of the electrocardiographand the output wire of the electronic blood pressure meter are connected with a peripheral computer host; and the output wire of the electrocardiograph and the output wire of the electronic blood pressure meter are connected with the peripheral computer host. Which overcomes the shortcomings of the traditional treadmill test machine that the connection is too much inconvenient to manage and distinguish, The product adopts automatic take-up and pay-off device to easily realize the management and convenience of connection, when not in use, it can realize automatic take-up, the whole is beautifuland tidy, avoiding the defect of traditional bandage fixation, convenient for medical staff to rescue the patients according to the actual situation, the rescue time is ensured, which is conducive torescue and convenient rescue.
