The utility model discloses the audio amplifier line of telescopic regulation relates to audio output accessory technical field, aims at solving the process of traditional audio amplifier line in use, and the skin is repeatedly rubbed with the storage bin wall and is easy to break, thereby reduces the shielding effect to external electromagnetic interference, leads the problem of the noise or noise of audio amplifier, including storage subassembly, guide component and audio line subassembly, the storage subassembly includes storage bin, sets up the wire inlet channel of storage bin's two sides, sets up the sliding slot of wire inlet channel inner side wall, sets up the carousel of storage bin one side, sets up the winding roller of storage bin inside and one end with carousel connection, sets up the winding groove of winding roller surface. The utility model discloses through the design storage subassembly, guide component and audio line subassembly, will the sliding friction of audio line main body telescopic time change for rolling friction, greatly reduced the friction resistance, makes the more smooth of storage and release, reduces the wear and tear of audio line main body surface simultaneously.

The utility model relates to water quality detection technical field, concretely is a kind of swimming pool water quality detection sampling mechanism, the upper end of sampling box body is detachably installed with upper cover, the lower part of sampling box body is provided with travelling mechanism, the inside of sampling box body is provided with water sample collection mechanism, the side of sampling box body is provided with lifting water intake mechanism, the travelling mechanism of sampling box body lower part can let whole sampling device run to the arbitrary position of swimming pool, and the positive and negative rotation of adjusting motor in lifting water intake mechanism is used to drive the rotation of external carousel, and rubber hose is wound in carousel, the vertical position of sampling port in the lower part of rubber hose can be controlled by the rotation of carousel, to cooperate travelling mechanism to sample the water body of any depth in any position of swimming pool, so that detection result is more accurate and comprehensive, and a plurality of different positions of water body can be obtained by sampling once, to facilitate detection personnel to compare different water samples.

This utility model discloses an online winch synchronous cable guiding device. It includes a cable storage mechanism for storing cables, a transition mechanism for transferring cables, and a cable pushing mechanism for placing cables and pushing them out of the container, all housed within a movable container. The cable storage mechanism is equipped with an encoder to collect current cable storage information, while the transition and pushing mechanisms are equipped with multiple position sensors to determine whether components have moved into position. Both the encoder and position sensors are connected to a control terminal. The advantages are: the multiple encoders and position sensors, after collecting feedback information, are used by the control terminal to coordinate and control each mechanism, achieving intelligent synchronous regulation. Compared to traditional multi-person manual operation, this saves considerable manpower while improving ease of use and operational accuracy. Multiple pulleys and rollers are also provided to assist cable movement, making the cable winding and unwinding process smoother.
