4results about How to "Reduce reset time" patented technology

The utility model belongs to the technical field of perforating equipment, concretely relates to a continuous puncher, including base, axle pin, tool holder, spring, cutter core group and gland, the middle part fixed mounting of base is tool holder, the middle part of tool holder is provided with the cutter core group of slidable, be provided with spring between cutter core group with tool holder, spring is used for the reset of cutter core group after the punch of tool holder on tool holder, the gland is covered with on tool holder, it is connected through axle pin rotation between the gland with tool holder. The utility model discloses through spring as reset piece, can drive cutter core group to rebound after punching, greatly shorten reset time, improve continuous punch efficiency, the cooperation of positioning column and the pre -hole cooperation of the piece to be punched, combine the limiting notched of tool holder, realize the double positioning of the piece to be punched, avoid the punch position deviation.

The utility model relates to a mobile phone rear cover fixing table, which is used for fixing a mobile phone rear cover before processing, and comprises a table body, and a driving piece, an L-shaped frame and a top plate which are sequentially mounted on the table body from bottom to top, wherein the number of the L-shaped frames is two, the L-shaped frames are oppositely and symmetrically arranged, and the corners of the two L-shaped frames are rotationally connected with the table body; the opposite ends of the two L-shaped frames are connected with a driving piece correspondingly, and the other ends of the two L-shaped frames extend to the two sides of the top plate correspondingly. After the mobile phone rear cover is placed on the top plate before being machined, the driving piece is started to pull down the opposite ends of the two L-shaped frames to enable the two L-shaped frames to rotate on the table body, the other ends of the two L-shaped frames can be made to get close to the top plate at the same speed and amplitude, uniform force is applied to the mobile phone rear cover placed on the top plate, and therefore the mobile phone rear cover is automatically centered and clamped; therefore, the fixing positions of the mobile phone hook covers are the same, and accurate positioning with consistent height is realized.

The utility model discloses a kind of refrigerators of convenient maintenance, it is related to refrigerator technical field, including mounting plate and connecting plate, the upper surface of mounting plate is equipped with refrigeration compressor by connecting plate, the front and rear both sides of connecting plate are equidistantly installed with first tooth block, the front and rear both sides of mounting plate are installed with vertical plate, the opposite side of movable plate is equidistantly installed with second tooth block;The upper surface of mounting plate is equipped with wire harness limiting groove in left and right sides. The refrigerator of convenient maintenance, by the pre-positioning cooperation of positioning column and positioning hole, rotating threaded rod on vertical plate, drive movable plate to move along guide telescopic rod, make first tooth block and second tooth block staggered engagement, realize the quick locking and loosening of refrigeration compressor, dismounting and resetting time when repairing can be greatly shortened without complex tool;Meanwhile, engagement structure can be transverse and longitudinal limit to compressor, ensure installation stable.

The utility model relates to the technical field of geomembrane processing, and provides an automatic geomembrane roll material feeding and cutting device which comprises a cutting assembly and a driving assembly. The cutting assembly comprises a first air cylinder and a second air cylinder, a first tool apron and a second tool apron are fixedly installed at the output end of the first air cylinder and the output end of the second air cylinder correspondingly, and a first cutter and a second cutter are fixedly installed on the opposite sides of the first tool apron and the second tool apron correspondingly. One side of the first tool apron and one side of the second tool apron are fixedly connected with a guide block; the geomembrane cutting device has the advantages that the tool nose at the longitudinal lower end of the first cutter can directly pierce a geomembrane to form an initial crevasse, and notch deformation caused by uneven jacking force distribution is reduced; the inclined blade face of the second cutter is matched, the two cutters are driven by the two-way lead screw to synchronously cut off from the middle to the two sides, notch deformation caused by uneven distribution of initial jacking force of the blades is avoided, double-cutter cutting is adopted, the cutting stroke is only half of that of a single cutter, and the cutting-off and resetting time is remarkably shortened.
