The unmanned vehicle with the radar jammer comprises an unmanned vehicle body, a shell is installed at the upper end of the unmanned vehicle body, a steering assembly is arranged in the shell, the upper end of the shell is rotationally connected with an installation base, an angle adjusting assembly is arranged at the upper end of the installation base, and a radar jammer is arranged at the lower end of the installation base. The upper end of the mounting seat is provided with a radar jammer body, and the rear side of the radar jammer body is provided with two reinforcing seats. Through the steering assembly, the rotation function of the radar jammer can be achieved, the direction of the whole unmanned vehicle body does not need to be adjusted, and the unmanned vehicle body is more flexible and convenient; the angle of the radar jammer can be flexibly adjusted according to actual requirements through the angle adjusting assembly, so that the jamming effect of the radar jammer is improved, and equipment can adapt to different working environments and task requirements.

The utility model discloses a marine metal ladder in the technical field of metal ladders, which comprises an upper ladder assembly and a lower ladder assembly, the upper ladder assembly is rotatably connected with the lower ladder assembly through a hinge, the lower part of the lower ladder assembly is connected with a plurality of telescopic rods, the upper ladder assembly is fixedly connected with a first ladder plate, and the lower ladder assembly is fixedly connected with a second ladder plate. The lower portion of the first ladder plate is fixedly connected with a double-end waterproof motor through a connecting bent rod. According to the metal ladder, the structural form that the upper ladder assembly and the lower ladder assembly are rotationally connected through the hinge is adopted, a linkage driving system composed of a double-end waterproof motor, a conduction shaft and a rotating shaft is combined, the angle rotation function of a ladder body is achieved, a plurality of telescopic rods are arranged at the bottom of the lower ladder assembly, and second ladder plates are fixedly connected to the telescopic rods; the height adjustability and the ground adaptation capability of the ladder are further enhanced, and the anti-skid performance and the overall stability of the ladder are greatly improved.

The utility model discloses a kind of side handrail folding mechanism and treadmill, including base and rotating connection on the handrail of base, handrail is provided with linkage pin assembly, linkage pin assembly includes first pin, second pin and trigger assembly, first pin and second pin are respectively set in different positions of handrail, base is spaced apart and is provided with first connecting hole and second connecting hole in first direction, first pin can be inserted into first connecting hole, and second pin can be inserted into second connecting hole, to make handrail lock in first direction;Base is also provided with third connecting hole corresponding with first pin or second pin in second direction, to make handrail lock in second direction;Trigger assembly is simultaneously connected first pin and second pin, can drive first pin and second pin move along the axial direction of handrail, to make handrail from first direction or second direction unlock, and can rotate on base.The utility model improves the stability of the whole when handrail is in locking state.

This application relates to the field of concrete core sample processing technology, and discloses a concrete core sample grinding device, including a support plate, a support platform, a linear moving module, a rotary motion module, a rotating plate, a support base, a first rotating shaft, cutting blades, and a grinding disc. In use, driven by an external force, the first rotating shafts on both sides rotate, which in turn drives the cutting blades and grinding discs on both sides to rotate synchronously. Driven by the rotary motion modules on both sides, both ends of the concrete core sample can be cut and ground simultaneously. Driven by the linear moving modules on both sides, the cutting and grinding amounts at both ends of the concrete core sample, as well as the feed rate during cutting and grinding, can be adjusted to complete the cutting and grinding work. Since the rotation of the cutting blades and grinding discs on both sides is achieved by driving the first rotating shafts on both sides, the number of driving sources is reduced.

The utility model discloses an interface switching device convenient to connect, include: the anus mirror mouth, the conversion component, the conversion component includes the connecting port no.
