4 results about "Cam follower" patented technology

This utility model relates to the field of sliding door technology, specifically to a sealed sliding door structure and device, including a door frame and a door panel that moves parallel to the door frame along the X-axis. A cam follower is provided on the door panel and is movably connected to the door frame. A guide groove is provided on the door frame near the door panel to guide the door panel's movement along the X-axis. At least one sealing section oblique to the X-axis is provided in the travel of the guide groove, causing the door panel to simultaneously displace in the Z-axis direction. Because the guide groove also includes an oblique sealing section in its sliding travel, when the door panel moves to the sealing section, the door, guided by the groove, will not only move along the X-axis but also displace in the Z-axis direction. This Z-axis displacement causes the door panel to move closer to the door opening of the device, forcing the sealing strip on the door panel to be compressed, thereby improving the sealing between the door opening and the door panel.

A protective cover for an insertion probe of a medical instrument. The cover contains a flexible tubular body that compliments the probe geometry and a radially disposed flange that surrounds the proximal end of the body. A series of snap-on fasteners removably connect the cover to the instrument. A camming surface is located on the outer face of the flange which coacts with a cam follower that is movably mounted upon the instrument to flex the cover sufficiently to open the fastener and release the cover from the instrument and move the cover axially toward the distal end of the tip.

The present application relates to the field of battery equipment manufacturing, in particular to a square case battery negative pressure formation equipment capable of automatically changing type. The detection assembly comprises a positive probe mounting plate, a negative probe mounting plate and a suction nozzle mounting plate. The positive probe mounting plate is provided with positive probes, the negative probe mounting plate is provided with negative probes, and the suction nozzle mounting plate is provided with negative pressure suction nozzles. The positive probe mounting plate, the negative probe mounting plate and the suction nozzle mounting plate are respectively provided with connecting blocks on both sides, and the connecting blocks are provided with cam followers. The positive probe mounting plate, the negative probe mounting plate and the suction nozzle mounting plate are installed on a guide rail mounting plate through guide rails, and the guide rail mounting plate is fixed on a fixed frame through a mounting connecting plate. The present application can meet the negative pressure formation requirements of different models of square case batteries, and has the characteristics of high docking precision and being suitable for mass production.

To provide an optical device capable of suppressing the increase in zoom torque. [Solution] A zoom lens 1 comprising a 2-group lens barrel 112, a 3-group lens barrel 113, a 4-group lens barrel 114, a cover member 123, a cam ring 105 having multiple cam grooves and rotatable around the optical axis, a guide tube 102 having multiple straight grooves and restricting the movement of the cam ring 105 in the optical axis direction, and multiple cam followers engaging with each of the multiple cam grooves, wherein when the cam ring 105 is rotated from the wide end to the telephoto end, with respect to the wide end, the maximum relative movement between the 2-group lens barrel 112 and the 3-group lens barrel 113 is A, the maximum relative movement between the 3-group lens barrel 113 and the 4-group lens barrel 114 is B, and the maximum relative movement between the 2-group lens barrel 112 and the 4-group lens barrel 114 is C, A
