This utility model relates to the field of corrugated pipe fittings, and in particular to a spherical sleeve for corrugated pipes, comprising a first hemispherical cylinder, a second hemispherical cylinder, and a positioning component. The positioning component includes a side limiting block, a first limiting block, and a second limiting block. Mounting platforms are provided on the outer surfaces of both the first and second hemispherical cylinders. The first limiting block is located in the middle of the mounting platform, and the second limiting block is located between the first limiting block and the side limiting block. A locking block is provided on the mounting platform. The first and second limiting blocks have adjusting grooves that match the locking blocks. A threaded hole is provided on the side of the locking block away from the mounting platform. By loosening the connecting bolts, the clamping force applied to the first and second limiting blocks can be reduced, and then the first and second limiting blocks can be adjusted to move towards the corrugations on the corrugated pipe, thus fixing the corrugated pipe and adapting it to corrugated pipes with small orifice diameters.

This application relates to a container rotation mechanism, a barcode scanning device, and a medical testing instrument. The container rotation mechanism includes a fixed base, a motor, a linkage shaft, an elastic component, and a clamping component. The motor is slidably mounted on the fixed base. The linkage shaft is coaxially connected to the motor's rotating shaft and passes through a screw hole; the sliding direction of the motor is parallel to the axis of the linkage shaft. The elastic component is connected to the linkage shaft. The clamping component is connected to the elastic component and has a recess adapted to the top of the container. On one hand, the clamping component presses against the top of the container to drive the container to rotate, preventing slippage and improving the accuracy of rotational barcode scanning. On the other hand, a single motor and linkage shaft can complete the movement close to the top of the container and drive the container to rotate. Furthermore, the elastic component allows the clamping component to adapt when contacting the top of the container. The structure is compact and simple, reducing costs and making it suitable for rotating containers of various heights.

The compressor shell assembly comprises a compressor shell and a sensor fixing frame, the sensor fixing frame comprises a fixing frame body and a connecting base, the fixing frame body is provided with a containing channel and comprises a top plate and side plates located on the two sides of the top plate, and the side plates are connected between the connecting base and the top plate; the distance between the positions where the side plates on the two sides are connected with the connecting base is L, the diameter of the temperature sensor is D, any point on the inner wall face of the top plate corresponding to the maximum deformation cross section is a point A, the distance between the point A and the center point O of the temperature sensor is OB after insertion, and the distance between the point A and the point O is OA before insertion. For the difference (OB-OA) between the OB and the OA of the same point, the maximum value of the difference corresponding to each point is MAX (OB-OA), and D-L < = MAX (OB-OA) / 3. According to the invention, the influence of uncontrollable force application factors caused by uncontrollable deformation caused by connection of the side plates and the connecting seats is reduced.

The invention relates to the technical field of robot control, and discloses a robot control method and device for an industrial pipeline, and the method comprises the steps: calculating a motion and posture coefficient based on a pitch angle, a roll angle, a motion speed and a motion acceleration of a robot; calculating an external force coefficient based on the cable dragging force and the operation counter-acting force; calculating a working condition attachment matching degree based on the instantaneous slip rate and the temperature under the motion and attitude coefficient and the external force coefficient; calculating a geometric coefficient of the pipeline based on the inner diameter, the bending radius and the inner local obstacle height of the pipeline; and based on the working condition attachment matching degree and the pipeline geometric coefficient, the target supporting arm pressing force is calculated, and the current supporting arm pressing force is adjusted to a target value. Through multi-source information fusion, the attachment state of the robot and the pipe wall and the geometric condition of the pipeline are dynamically evaluated, self-adaptive adjustment of the pressing force of the supporting arm is achieved, and the movement stability, passing ability and operation reliability of the robot in the complex pipeline environment are effectively improved.

The utility model discloses a kind of adsorption type dehumidification runner sealing structure, including structural frame and dehumidification runner;Sealing unit is arranged between the both ends of dehumidification runner and the structural frame;The sealing unit includes the outer ring flange of the outer periphery of dehumidification runner and the sealing ring of the structural frame;The cross-sectional shape of the sealing ring is Y type formed by three lips;One of the Y type the lip is set on the structural frame, and the other two lips are abutted with adjacent outer ring flange.The elastic force direction of sealing ring is along the axial direction of dehumidification runner, can bear greater air pressure.Under the premise of not increasing the friction resistance of sealing strip, reduce the leakage of air, improve the sealing performance of dehumidification runner;Compression intensity is smaller, and the rotation resistance of dehumidification runner is smaller, due to the self-lubricating characteristics of fluorine like glue, the friction resistance of this sealing structure has obvious reduction, hollow layer can isolate heat conduction, dry and wet air has no leakage.

This utility model discloses a rubber ring fixing mechanism, comprising: a wire clamping block with a clamping portion; a rubber ring disposed in the clamping portion; and a positioning member passing through the wire clamping block and the rubber ring. The rubber ring is an elastic body. A tail wire is threaded between the rubber ring and the clamping portion. The rubber ring and the clamping portion are in an interference fit to press and straighten the tail wire, ensuring that the clamping force of the rubber ring on the tail wire is less than a preset pressure value. This rubber ring fixing mechanism, through the wire clamping block, the rubber ring, and the positioning member forming an interference fit system, uses an elastic body. The elastic body's compression deformation generates a constant contact pressure, achieving automatic clamping and straightening of the tail wire, avoiding manual adjustment, and significantly reducing the dispersion of clamping force. Furthermore, by ensuring that the clamping force of the rubber ring on the tail wire is less than the preset pressure value, plastic deformation of the wire is prevented.
