This invention discloses a signal detector for power transmission lines, relating to the technical field of signal detectors for power transmission lines. The signal detector includes a rectangular frame, with a fixing mechanism fixed to the upper surface of the frame. The fixing mechanism includes a fixing plate, a slider, an arc-shaped plate, a limiting spring, a sleeve plate, and a threaded rod. The fixing plate is fixedly connected to the upper surface of the rectangular frame. When the device is impacted, the shock-absorbing device, in conjunction with a hinge rod, a sliding rod, a thrust spring, and a friction block, reduces the downward sliding speed of the placement plate. This prevents the components inside the detector from colliding with each other due to the different speeds of their downward movement or resetting compared to the outer casing, thus avoiding damage to the internal components. This invention solves the problem of component damage caused by inertia leading to a difference in movement speed between the internal components and the outer casing.

This utility model discloses a door catcher, belonging to the field of door accessory technology, including a catch base and a catch head. One end of the catch base has a first connector with a first connecting surface; the end of the catch head is movably connected to a universal joint, which has a second connecting surface that can fit against and magnetically connect with the first connecting surface. The second connecting surface rotates with the universal joint to adjust its orientation. During installation, the catch head is mounted on the door, and the catch base is installed at the corresponding position at the same height on the wall. After completion, the door is brought close to the wall, so that the end of the catch head is close to the end of the catch base. The universal joint is adjusted so that the second connecting surface faces the first connecting surface until they are fully fitted. By utilizing the universal rotation of the universal joint, the second connecting surface can be adjusted at multiple angles in three-dimensional space, achieving matching of the door catcher's adsorption angle with the door's opening and closing trajectory, avoiding problems of loose connection due to minor errors when fixing the catch head and catch base.

In this utility model, the adsorption structure composed of suction cups, sliding rods, and air bladders can automatically adjust according to the unevenness of the flexible board surface. When the flexible board surface has different heights, multiple sets of suction cups can contact the flexible board at different heights. The stretching of the air bladder generates negative pressure, achieving a tighter and more uniform adsorption of the flexible board surface. This avoids problems such as weak adsorption and displacement caused by uneven flexible board surfaces, ensuring the stability and safety of the flexible board during the transfer process and improving processing quality.
