4results about How to "Compression stability" patented technology

This utility model relates to the field of spring manufacturing equipment technology, specifically a long spring standing machine, including a rotating frame and a compression spring device. The bottom of the rotating frame is equipped with a drive motor and a reduction gear. The reduction gear meshes with a transmission gear ring on the side of the frame to achieve rotation of the rotating frame. Multiple fixed spring columns are evenly distributed on the top of the rotating frame. The compression spring device is located on one side and can be multiple in number, including a lifting frame, a motor frame, a lifting motor, a ball screw, and a pneumatic pump. The lifting motor drives the ball screw, causing the motor frame and pneumatic pump to move up and down. The compression spring tube at the end of the pneumatic telescopic rod is vertically aligned with the fixed spring column. A compression ring is installed inside the compression spring tube. A limiting tube is installed at the bottom of the fixed spring column to ensure stable spring compression. The bottom of the lifting frame is slidably mounted on a slide rail via a slider, and horizontal adjustment is achieved by a screw threaded rod driven by a rotating motor. This equipment has precise positioning, strong adaptability, and effectively improves the efficiency and quality of spring standing.

The application relates to the technical field of medical devices, and provides a quick fixing and releasing mechanism, which comprises a mounting seat, a rotating piece, an eccentric piece and an elastic piece, the eccentric piece is limited to rotate in the mounting seat, the elastic piece abuts one side of the eccentric piece, one end of the rotating piece is limited to rotate in the mounting seat and abuts one side of the elastic piece away from the eccentric piece; when the eccentric piece does not compress the elastic piece, the elastic piece is in a natural state, the rotating piece can rotate in the mounting seat, when the eccentric piece rotates to compress the elastic piece, the elastic piece abuts and presses one side of the rotating piece, and the rotating piece is fixed. Based on the quick fixing and releasing mechanism, the support pad can be conveniently relaxed or fixed, and the patient experience and nursing efficiency are improved.

This utility model discloses a real-time PCR instrument adapted to the placement of test tubes of different sizes. It relates to the technical field of real-time PCR instrument equipment. The instrument includes a main body with a mounting mechanism for test tube detection. The mounting mechanism includes a lifting component and a detection box connected to the main body via a sliding component. Test tubes of different sizes are inserted from top to bottom into a hole composed of a positioning ring and an arc-shaped ring. When the outer wall of the test tube contacts and presses downward against the positioning ring, the positioning ring compresses a spring, causing it to move. The spring's rebound force is converted into a uniform and gentle radial clamping force on the outer wall of the test tube, thus initially adapting to and holding the test tube, achieving initial positioning. The positioning force can automatically adjust according to the size of the test tube, achieving good positioning for test tubes of different diameters, improving the instrument's adaptability to test tubes of different specifications.

The utility model discloses a silkworm silk fixing device for silk quilt processing, including support station, the four corners of support station are fixed with guide sleeve no.
