The invention discloses a medical cardiology department clinical operation auxiliary device, and relates to the technical field of medical auxiliary instruments.The medical cardiology department clinical operation auxiliary device comprises a base, a plurality of supporting rods are installed on the upper portion of the base, a first supporting plate is jointly installed on the outer sides of the supporting rods, and a plurality of rotating rods are rotationally connected to the side, away from the first supporting plate, of the base; an opening groove is formed in the end, away from the base, of the rotating rod, a sliding wheel is rotationally connected to the inner side of the opening groove, a plurality of first rubber blocks are installed on the outer side of the sliding wheel, an automatic stop assembly used for the sliding wheel is jointly arranged on the multiple supporting rods, and the automatic stop assembly comprises movable rods arranged on the supporting rods. According to the device, fixation can be automatically relieved, and the sliding wheels can be automatically locked when movement is not needed, so that an operator does not need to manually adjust or unlock when needing to move the device, the operation process is greatly simplified, and the placement space can be adjusted according to requirements for use.

The utility model relates to the technical field of gallium nitride single crystal growth, in particular to a large-size gallium nitride single crystal HVPE growth reactor. The reactor comprises a furnace chamber and a furnace body; the furnace body comprises a furnace cover, a furnace barrel, a furnace chassis and a heater outside the furnace barrel; a furnace chamber is formed among the furnace cover, the furnace barrel and the furnace chassis; a gallium boat and a substrate support are sequentially arranged in the furnace chamber from top to bottom, the upper end of the gallium boat is connected with the furnace cover, the gallium boat is used for storing gallium and generating gallium chloride, and the substrate support is connected with the furnace chassis; a tail gas pipeline is connected outside the furnace chassis; and an ammonia gas inlet pipe is arranged on the furnace cover. An isolation gas pipe is arranged in the gallium boat, an upper cavity protection sleeve and a lower cavity protection sleeve are arranged on the inner wall of the furnace barrel, and protection gas is introduced between the upper cavity protection sleeve and the inner wall of the furnace barrel. Through the protection effect of gas purging outside the furnace chamber protection sleeve and the upper chamber protection sleeve, parasitic deposition of polycrystalline gallium nitride on the inner wall of the furnace chamber is avoided, and the service life of the gallium nitride single crystal HVPE growth reactor is prolonged.

This application belongs to the technical field of air conditioning and discloses an air conditioning control box and air conditioning equipment. The air conditioning control box includes a housing, electrical components, and a first copper busbar. The electrical components and the first copper busbar are both disposed within the housing, and the first copper busbar is electrically connected to the electrical components. The length direction of the first copper busbar is arranged along a first direction, and the width direction of the first copper busbar is arranged along a second direction, both of which are parallel to the horizontal direction. This application can reduce the occupancy rate of the first copper busbar in the height space of the control box, thereby expanding the space area for wiring within the air conditioning control box; on the other hand, it can reduce the height dimension of the air conditioning control box, thereby reducing the volume of the air conditioning control box.
