Apparatus and methods of their use are described for engaging a pumping cartridge with a pump drive. In certain embodiments, the cartridge, comprising a cylinder and a movable piston assembly, is initially assembled or subsequently positioned so that the distance between the attachment point on the piston assembly for coupling to a drive assembly, and a reference point on the cylinder, is greater than the maximal distance that will be encountered during normal oscillation of the piston during use. The cartridge, in certain embodiments may be pressed into a drive assembly having means for immobilizing the cartridge and means for coupling the piston assembly to the driveshaft. In certain embodiments, when the cartridge is fully inserted into the drive assembly, the piston is pressed into the cylinder sufficiently to establish a selected distance so that the piston shaft is in the proper position to engage with a coupling mechanism carried on the driveshaft.

An auto-alignable knob for a home appliance includes an offspring box self-connectable with a valve shaft. A mobile box has at least one lateral face including a pin. The mobile box is coupled to the offspring box to allow a free movement relative to one another along a first axis. A fixed box includes an indentation and a groove. The mobile box is insertable to the fixed box by insertion of the pin of the lateral face through the groove. The pin of the mobile box provides a respective degree of freedom to the mobile box relative to the indentation of the fixed box along at least a second axis normal to the first axis. A mechanical coupling established between the indentation of the fixed box and the pin of the mobile box is configured to provide a degree of rotational freedom about one of the axes, and a combined mechanical coupling established between the offspring box, the mobile box and the fixed box is configured to provide a respective degree of freedom along a third axis perpendicular to the first and second axes.

A machine for shaving and pressing ice cream, the machine being capable of: obtaining shaved ice cream having a uniform wave shape and roughness or softness desired by an ice cream eater, since a pressing plate is rotated and moved downwards by a rotary motor embedded in a motor fixing case of a shaving and pressing machine body part and the ascending and descending drive of a driving actuator, thereby easily shaving the ice cream contained in a container in multiple stages; and easily extracting soft ice cream by stopping the driving of the rotary motor and pressing semisolid ice cream, contained in the container, by means of the descending of the pressing plate.

A non-pull cord operated blind structure includes a retaining box, a recoiling spring element, a movable member, a control button, and a cover wherein the retaining box is equipped with an engaging cavity having a locating rod protruding at the center thereof to be registered with the movable member thereby, and the recoiling spring element has an inserting hook piece and a fixing piece disposed at both ends thereon to be securely attached to a recess of the locating rod thereof and an engaging hook of the movable member respectively thereby. The movable member is provided with a retaining chamber having two opposite abutting blocks with tapered guide slopes protruding at the inner periphery thereon to be abutted against tapered locating plates of the control button so as to precisely locate the movable member with retaining cords collected therein. Thus, the recoiling spring element is activated to compress tight or rebound loose by the retaining cords which is either stretched out by a lower beam pulled downwards after the control button is pushed to detach the locating plates thereof off from the abutting blocks thereof in the unfolding operation of a blind, or released from the gravity pull of the lower beam raised upwards in the folding operation thereof, facilitating an easy and fast adjustment of the non-pull cord operated blind structure.

The invention relates to the technical field of cabinet showing and sale, and discloses a food cabinet showing device. The food cabinet showing device comprises a base, wherein adjusting boxes are fixedly mounted on two sides of the top end of the base; a fixing box is fixedly mounted in the middle of the top end of the base; two sides of the fixing box are separately connected with side surfacesof the adjusting box fixedly; a double-shaft motor is fixedly mounted on the bottom of a cavity of the adjusting box; rotating shafts are fixedly mounted on two outputting shafts of the double-shaft motor separately; and the other ends of the two rotating shafts successively penetrate through the fixing box and the adjusting box and extend to the bottom end of the cavity of the adjusting box. According to the food cabinet showing device, the double-shaft motor rotates to drive the rotating shafts to rotate, by transmission cooperation of a driving gear, a driven gear, a lead screw and a movingplate, a showing plate moves vertically, thus, the height of a food cabinet is adjusted, people who are away from the showing device in a showing field can see the food cabinet, and the practicalityof the showing device is improved.
