This utility model relates to the field of soft-seal ball valve technology and discloses an anti-chewing soft-seal ball valve, including a valve body, a valve stem rotatably connected inside the valve body, connecting pipes fixedly connected to both sides of the valve body, a protective component and a dispersion component provided on the side wall of the valve body; the protective component includes a first protective cover, one side wall of which is slidably connected to the side wall of the connecting pipe, a second protective cover rotatably connected to one side wall of the first protective cover, and a fixed frame fixedly connected to one side wall of the second protective cover. In this utility model, by sliding the first protective cover to a suitable position on the connecting pipe, pulling the connecting rod causes the locking pin to retract into the connecting frame and compress the first spring; rotating the second protective cover to wrap around the valve body releases the connecting rod, and the first spring resets, causing the locking pin to insert and fix, thus achieving rapid fixation of the protective cover, solving the problem of soft-seal ball valves being easily chewed by animals and causing component damage, and improving the ease of installation of the protective structure.

The utility model relates to special carbon material processing equipment technical field discloses a special carbon material forming press with pre -press function, including base, the base side wall fixedly connected with guide post, the guide post side wall fixedly connected with top plate, the top plate inside fixedly connected with hydraulic cylinder, the hydraulic cylinder output fixedly connected with slide, the slide side wall is provided with buffer assembly, and the base inside is provided with top die assembly, the buffer assembly includes damper, the slide bottom fixedly connected with connecting column, the guide post side wall slidingly connected with press plate, the press plate side wall fixedly connected with connecting frame, in the utility model, hydraulic cylinder drives slide to slide down, and the connecting column, connecting block etc. linkage, buffer through damper and extension spring cooperation, make force gradually to press plate to pre -press, press material, solved the problem that special carbon material is easy to break down because of excessive impact, improved the quality and stability of pre -press and press.

This utility model relates to the technical field of smart home control, and in particular to a control switch for smart homes, including a mounting base with a protective locking mechanism on one side surface of the mounting base. This smart home control switch, through the protective locking mechanism, solves the problem of inconvenient opening and closing of existing protective structures, enabling flexible opening and closing of the protective cover for easy operation and maintenance of internal components. The inclusion of a release button, a reset spring, and circuit pads allows for precise control of smart home devices, improving control reliability. The rough surface on the outer side of the control knob facilitates user selection of different smart home devices, enhancing operational convenience. The design of the charging port, mounting base, protective cover, and release block solves the problem of easily damaged charging ports, ensuring the safety and stability of the charging port, extending the device's lifespan, and improving the overall safety and stability of the device.

The rock dynamic compression testing device and testing method are provided, which comprise a Hopkinson pressure bar testing system, an acoustic emission detection device is arranged between an incident rod and a transmission rod, the acoustic emission sensor protection device is made of a material with high axial stiffness, and comprises a protection device upper shell and a pair of protection device side shells, which form a ring-shaped shell, a sample is located in the ring-shaped shell, a side shell main track and a side shell auxiliary track are arranged on each of the pair of protection device side shells and are arranged in parallel, an acoustic emission sensor is installed on the side shell main track, an acoustic emission sensor back baffle outside the acoustic emission sensor is installed on the side shell auxiliary track through a back baffle diagonal screw nut 7, and the acoustic emission sensor is connected with a data processing system through a data acquisition line. The rock dynamic compression testing device and testing method can protect the acoustic emission probe during dynamic loading and will not affect the damage characteristics and strain distribution of the rock determined by the acoustic emission detection system.

The application provides an impact-resistant damper. The impact-resistant damper comprises an eddy current damping unit and a buffer damping unit. The eddy current damping unit comprises a ball screw drivingly connected with a controlled structure and a fixed outer sleeve arranged outside the ball screw. The buffer damping unit comprises a resilient stiffness member arranged close to a driving connection end of the ball screw. One end of the resilient stiffness member is sleeved outside a screw rod of the ball screw, and the other end of the resilient stiffness member is connected with the outer sleeve. When the controlled structure reaches a preset displacement value or a preset impact value, one end of the resilient stiffness member is deformed to start the buffer damping unit. The application has the advantages of guaranteeing the vibration reduction and impact resistance effect of the controlled structure under large displacement and impact, compact structure and the like.
