6results about How to "Flexible size change" patented technology

This utility model relates to a special refrigeration machine for medical waste. The refrigeration cabinet (2) has several folding storage support units inside its cabinet body (21). Each folding storage support unit includes a support rod (3) and two support units (4) for supporting the support rod (3). Each support unit (4) includes a mounting base (41) and a mounting block (42) mounted on the mounting base (41). A sliding column sleeve (43) is rotatably connected inside the mounting block (42), and a sliding column (44) is slidably connected inside the sliding column sleeve (43). The support rod (3) is positioned between the sliding columns (44) in the two parallel support units (4). Compared with the prior art, this utility model allows for flexible changes in the size and layout of the storage space by flipping the support rod (3) and adjusting the extension length of the sliding column (44). This enables the storage support to adapt to different sizes of medical waste, avoiding space waste and solving the problem of low internal space utilization efficiency in refrigeration machines.

The utility model relates to a kind of nonwoven fabric paving net negative pressure air suction device of adjustable, including negative pressure box, the outside of the negative pressure box is fixedly connected with negative pressure pipe, the top of the negative pressure box is set to opening, the top of the negative pressure box is fixedly connected with support plate, multiple sets of second negative pressure holes are equipped on the support plate, the position of corresponding second negative pressure hole on the support plate is equipped with sliding groove, the sliding groove is communicated with second negative pressure hole, sliding connection is achieved in the sliding groove with sliding plate, the outside of the sliding plate is fixedly connected with multiple sets of adjusting plate;In the utility model, according to the different types of nonwoven fabric adjustment air suction area, push sliding plate to slide, sliding plate drives adjusting plate to slide, adjusting plate slides adjustment, so second negative pressure hole's air suction area can be adjusted;Again open negative pressure fan, negative pressure fan is inhaled air in negative pressure box by negative pressure pipe, generates negative pressure;So sliding plate can be flexibly changed air suction area size in sliding process.

The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to an omnidirectional flight unmanned aerial vehicle based on a passive hinge type vector power system. Comprising a machine body, vector power systems and machine arms, the three machine arms are arranged on the machine body in the circumferential direction at equal intervals, and the tail ends of the three machine arms are connected with the three vector power systems correspondingly; the vector power system comprises a power system fixing frame, a two-shaft connecting piece and a plurality of power rotors, one end of the two-shaft connecting piece is rotationally connected with the vehicle arm, the other end of the two-shaft connecting piece is rotationally connected with the power system fixing frame, and the power rotors are arranged on the power system fixing frame. The power system fixing frame is of an H-shaped structure, and four power rotors are arranged at the four ends of the power system fixing frame correspondingly. The whole power vector is changed under the condition that no extra actuator is added, hovering in the air can be achieved in any posture, and omni-directional movement is achieved under the condition that any posture is kept.

The utility model discloses a vibrating filter belongs to vibrating filter technical field, including body, storage tank and adjusting part, the storage tank sets up on the body, has been seted up in the storage tank and has the discharge gate, adjusting part sets up on the storage tank, the adjusting part includes the adjusting plate of adjusting discharge gate size, is connected with the adjusting lever on the adjusting plate, a plurality of hook plate of different height is arranged to the both sides of adjusting lever, the hanging rod that hangs on the hook plate is fixed on the adjusting lever, through the size of adjusting the discharge gate of storage tank, can change the flow of material from the discharge gate, can reduce the thickness of material layer at fixed landing point, reduce the package and extrusion of upper layer big material to lower layer small material, make small material more easily contact screen and smoothly screen, effectively solve the problem of not enough filtration.

The application belongs to the technical field of landing gear accessory production, and particularly relates to a compression strength detection system and method for a landing gear combined fork arm, which comprises a load assembly and a compression strength detection assembly. The load assembly is used for loading the combined fork arm and adjusting the unfolding angle of the combined fork arm according to detection requirements. The compression strength detection assembly is used for detecting the dynamic load compression strength of the anti-twist arm at different positions and the dynamic load compression strength of the hinge at the connecting position under different unfolding angles. The compression strength detection assembly comprises a suspension reset mechanism, a hammer box, an adjustable dynamic load and a counterweight adjustment mechanism. The hammer box is supported by the suspension reset mechanism and can be horizontally displaced with the suspension reset mechanism. The suspension reset mechanism can adjust the height position of the counterweight load frame in the adjustable dynamic load. The side end of the hammer box is provided with the counterweight adjustment mechanism which can adjust the number of counterweight blocks in the counterweight load frame. The application simulates actual working conditions, comprehensively detects, flexibly adjusts impact energy and adapts to different detection requirements.
