The invention discloses a computer mainboard reinforcing device with heat dissipation and dust prevention functions. The computer mainboard reinforcing device includes a shell, wherein a movable blockand a movable plate are arranged on one side of the shell; the movable block is divided into two first block bodies and two second block bodies, the two first block bodies are symmetrically connectedto the upper side wall of the shell in a sliding mode, the two second block bodies are symmetrically connected to the lower side wall of the shell in a sliding mode, the movable plate comprises a first plate body and a second plate body, and the first plate body is connected to the upper side wall of the shell in a sliding mode. When the arc-shaped grooves in the reinforcing plates and the clamping blocks are located at the same horizontal position, the reinforcing plates are clamped; under the action of a third spring, a clamping block can be popped up and propped against an arc-shaped groove; the reinforcing plate is further fixed, the stability of the reinforcing plate is guaranteed, and meanwhile, the reinforcing plate can slightly float up and down under the action of the second springs when vibration is generated, so that the damping effect is achieved, the main board body is protected against damage, and the service life of the main board body is prolonged.

The invention belongs to the field of preparation of traditional Chinese medicinal materials, and particularly relates to a magnetic self-rotating baking frame. The magnetic self-rotating baking framecomprises a base, a fixed column is fixedly connected to the upper end of the base, a cavity is formed in the fixed column, a reset spring is fixedly connected to the inner bottom of the cavity, theupper end of the reset spring is fixedly connected with a first magnetic sliding block, the upper end of the first magnetic sliding block is fixedly connected with a second magnetic sliding block through a connecting rod, a permanent magnet ring is rotationally connected to the outer side wall of the fixed column, an annular rotating disc is fixedly connected to the outer side wall of the permanent magnet ring in a sleeving mode, a rotating head is rotationally connected to the upper end of the fixing column, one side of the rotating head is fixedly connected with the upper end of the annularrotating disc through an L-shaped connecting rod, the other side of the rotating head is fixedly connected with a connecting pipe, the lower end of the connecting pipe is fixedly connected with the upper end of the annular rotating disc through a heat conducting pipe, the inner bottom surface of the heat conducting pipe is fixedly connected with a memory spring, and the upper end of the memory spring is fixedly connected with a first piston block. According to the baking frame, in the drying process, positions of traditional Chinese medicinal materials can be automatically adjusted, so that the drying effect of the traditional Chinese medicinal materials is better.

The invention discloses a solid-fluid rocket engine annular-seam-type plug nozzle. The solid-fluid rocket engine annular-seam-type plug nozzle comprises a ring laryngeal mask, a nozzle pressing plate, a nozzle shell body, a plug cone and a thermal-insulating plate. The ring laryngeal mask is installed at the outlet end of the nozzle shell body through the nozzle pressing plate, a boss is installed in the nozzle shell body through a ribbed plate, and the plug cone is arranged in the laryngeal part of the ring laryngeal mask in a suspended mode and connected with the boss; and the peripheral surface of the plug cone is matched with the laryngeal part of the ring laryngeal mask to form a convergent section and an expansion section, the thermal-insulating plate is installed at the inlet end of the nozzle shell body, and straight slots communicating with each other are formed in the thermal-insulating plate and the ribbed plate. High-temperature and high-pressure fuel gas in a combustion chamber of a solid-fluid rocket engine enters through the inlet end of the nozzle shell body, the fuel gas gradually accelerates at the convergent section, and after the sound speed is reached at the laryngeal part of the ring laryngeal mask, the fuel gas flows into the expansion section and continuously accelerates to the supersonic speed. The solid-fluid rocket engine annular-seam-type plug nozzle is suitable for the solid-fluid rocket engines with different working heights.
