The utility model discloses a model car pedal mechanism which comprises a machine frame and a pedal body, a bending frame is arranged on one side of the machine frame, an adjusting frame is arranged at one end of the bending frame, an adjusting component is arranged between the bending frame and the adjusting frame, a moving component is arranged between the adjusting frame and the pedal body, and the moving component is connected with the bending frame. The adjusting part comprises a notch formed in one end of the bending frame, a screw rod connected with one end of the adjusting frame, a knob connected with one end of the bending frame and a rotating groove formed in one end of the bending frame. The problems that when the position of a pedal of an existing pedal mechanism is adjusted, an adjusting frame needs to be rotated, the whole pedal can be driven to rotate, it cannot be guaranteed that the pedal is reset to the original state during adjustment, the pedal is likely to incline, normal use of the pedal is affected, meanwhile, pedal height adjustment is relatively tedious, adjustment efficiency is affected, and the service life of the pedal is influenced are solved. And therefore, the practicability is reduced.

This invention discloses a powder mixing pharmaceutical device for pharmaceutical engineering, comprising a cylindrical drum, a fixed plate fixedly connected to the top of the drum, an openable cover hinged to the outer wall of the fixed plate, a motor fixedly connected to the top of the fixed plate, a connecting rod fixedly connected to the output end of the motor, and a mixing mechanism provided on the outer wall of the connecting rod. This relates to the field of pharmaceutical technology. By setting up the mixing mechanism, the bearing disc B rotates on the outer wall of the annular sleeve, causing the spring to deform. Simultaneously, the rotation of the threaded rod and the bearing disc B causes the threaded rod and the bearing disc B to rotate synchronously. Furthermore, the bristles on the outer wall of the stirring rod are agitated by the rotating threaded rod, causing the bristles to rebound due to their own elasticity, rapidly agitating the powder and improving the powder mixing efficiency. The rapid rebound of the bristles also disperses any clumps of powder adhering to the bristles, preventing adhesion from affecting the mixing effect.

This utility model provides an indoor ventilation device, relating to the field of indoor ventilation technology. It includes an outer frame and several guide vanes disposed within the outer frame. A chamber is formed at the bottom of the outer frame. The blade shafts of the guide vanes pass through the bottom of the outer frame and extend to be rotatably connected to the bottom of the chamber. An electric push rod is fixedly installed on one side of the top of the chamber. A slide bar, which is inserted into the inner wall of the chamber, is fixedly installed at the telescopic end of the electric push rod. The slide bar slides along the arrangement direction of the guide vanes, and a connecting frame is fixedly installed on the surface of the slide bar near each guide vane. The extension of the electric push rod pushes the slide bar to slide, causing the connecting frame to move. The connecting frame then pushes a rotating arm and a ring to rotate, thereby rotating and opening the guide vanes fixedly installed with the ring. In this solution, the opening and closing of the guide vanes depends on the extension and retraction of the electric push rod and is not affected by outdoor wind speed.

The utility model discloses a yarn tension control device of a warp knitting machine, and relates to the technical field of tension control devices. The device comprises a base table, an adjusting mechanism and an anti-rotation mechanism are arranged on the base table, the adjusting mechanism comprises a threaded sleeve rotationally connected to the inner wall of the base table, the inner wall of the threaded sleeve is in threaded connection with a threaded rod, and the top of the threaded rod is fixedly connected with a sliding platform; the top of the base table is fixedly connected with two first supports, the outer wall of the sliding platform is connected with the two first supports in a sliding mode, the inner wall of the base table is connected with a plurality of sliding rods in a sliding mode, and the sliding rods penetrate through the sliding platform. According to the yarn tension control device of the warp knitting machine, the adjusting mechanism is arranged, so that the problem that in the using process of an existing yarn tension control device of the warp knitting machine, the tension control amplitude is inconvenient to adjust, and therefore the requirements of different yarn materials and knitting technologies for the tension control amplitude are difficult to meet when diversified yarn materials and complex knitting technologies are coped with is solved.
