The invention belongs to the technical field of bearings, and particularly discloses a seal bearing. The seal bearing comprises an inner ring, an outer ring, a ball and a seal end cover; circular grooves are arranged on two end faces of the outer ring and the inner ring, the ball is arranged between the inner ring and the outer ring, two circular protrusions are coaxially arranged on one end faceof the seal end cover, the seal end cover is arranged on the left and right end faces of the inner ring and the outer ring through the circular protrusions and the circular grooves in the outer ring and the inner ring, a contact inner ring and a contact outer ring are arranged on the contact parts of the inner ring and the outer ring and the ball, and limiting rings are arranged on the inner ringand the outer ring; and an annular boss is arranged at the position, between the inner ring and the outer ring, of the seal end cover, and the portion where the annular boss makes contact with the ball is in an arc shape. Effective seal of the bearing is achieved, meanwhile, the seal end cover can be automatically locked on the inner ring and the outer ring, mounting is convenient, work reliability is high, and lubricating is ensured.

The present invention relates to a tubular motor manual electric clutch controller. An arc rack is matched with a spur gear at a rotating rod and a pulley at a slide rod. A smaller traveler at the slide rod is matched with a slide way buckle which is connected with an external end cover. The slide rod is equipped with more than one pulley and is connected with a pull rod with a spring. The arc rack is connected with a rotating shaft which is provided with a torsional spring. The rotating shaft is fixed on an internal end cover. The original slide rod is decomposed into two independently moving parts of the slide rod and the arc rack to reduce the spring. The slide rod is provided with a bevel and is equipped with the pulley. The movement of the slide rod is changed into the sliding of the pulley. The pulley can be departed from or pressed on the arc rack just by very short distance of the movement of the pull rod. The arc rack rotates for certain degrees along the rotating shaft and can be departed from or be meshed with the spur gear. The tubular motor manual electric clutch controller can achieve the great just by few pull. The tubular motor manual electric clutch controller is a manually operated controller saving most labor at the prior market and has simple and compact structure and low cost. The tubular motor manual electric clutch controller can be installed at rolling doors with different specifications and sizes and has fast pulling speed and high efficiency.

The invention belongs to the technical field of automobile manufacturing and particularly relates to a reinforcing iron sheet automatic mounting device for an automobile door handle cover. The reinforcing iron sheet automatic mounting device for the automobile door handle cover is characterized in that a door handle cover positioning mechanism, a reinforcing iron sheet limiting block, a working mechanism, a door handle cover clamping mechanism and a pneumatic double-control controller are fixedly connected to a fixed bottom plate. The reinforcing iron sheet automatic mounting device for the automobile door handle cover solves the problems that due to the phenomena of tedious operation, large labor intensity, long beat time and easiness in installation without being in place by manually adopting a reinforcing iron sheet of the door handle cover, the reinforcing iron sheet after installation deforms with potential safety hazards, and the door handle cover is easily damaged to cause scrapof a product and has the beneficial effects that by adopting the door handle cover positioning mechanism for positioning, the door handle cover clamping mechanism for clamping and the working mechanism and the pneumatic double-control controller for realizing feeding or material returning, the structure is compact, mounting of a special-shaped door handle cover reinforcing iron sheet can be adapted, and the mounting efficiency, accuracy and safety of the automobile door handle cover reinforcing iron sheet are improved.

The invention provides an internal feeding tool. A tool bar is fixedly connected into the front section of a central through hole in a tool seat through a tool bar locking part. A tool bit is arranged in a radial groove in the front section of a central hole in the tool bar. A guiding slope at the inner end of the tool bit is matched with a tool bar ejector rod penetrating into the central hole of the tool bar to enable the tool bar ejector rod to push the tool bit to stretch out of the tool bar along the radial groove. The front section of the tool bar is sleeved with a tool bar guiding sleeve with the outer diameter being adaptive to the inner hole size of a machined workpiece. Tool feeding precision is high, and the cutting process is stable. The tool bar is inserted into a hole of the workpiece to be machined and is positioned through the tool bar guiding sleeve, repeated adjustment of the concentricity is not needed, and positioning is convenient. The guiding sleeve enables the moving track of the tool bar relative to the machined workpiece to be stable, machining precision is high, the levelness of a machined surface is good, and key groove machining symmetry is improved. The tool cost is low, machining and manufacturing is convenient and rapid, and the tool can be suitable for different machining hole diameters and key groove widths and can machine arc grooves and spiral grooves in blind holes and stepped holes.

The invention discloses a cam-connecting rod type mechanical three-dimensional parking device comprising cams fixed to the ground, driving shafts rotatably mounted on the cams, a car dragging plate horizontally moving in an inverted-L-shaped track, a connecting rod assembly in transmission connection between the driving shafts and the car dragging plate, and a power device for driving the drivingshafts to rotate so as to enable the connecting rod assembly to drive the car dragging plate to horizontally move in an inverted-L-shaped track. The connecting rod assembly comprises a driving connecting rod assembly and a balance connecting rod assembly. A vertical space can be fully utilized by means of the structure, the number of parking spaces is increased twice under the condition that no additional road area is occupied and parking on original parking spaces is not affected, and meanwhile, different driving devices adopted for maintaining synchronism are omitted, the failure rate is lowered, and the safety coefficient is increased.

The invention discloses a stable and reliable automatic unlocking device for a drawer in a cash register box, which comprises a box body and a bottom plate arranged on the box body; an electromagnet is arranged on the bottom plate, an iron core is movably arranged in the electromagnet, a retainer ring is arranged on the iron core, a reset spring is nested in the iron core at the inner side of theretainer ring, a strip-shaped draw bar hole is arranged in the iron core at the outer side of the retainer ring, the bottom plate is also provided with a rotating pin, a swing plate is movably arranged on the rotating pin, a striking head for unlocking is arranged at the outer side of the swing plate, both ends of the swing plate are respectively provided with a protruding outward draw bar and anupright downward limit bar, the draw bar protrudes into a draw bar hole, the bottom plate is also provided with a circular arc-shaped limit hole, and the limit bar protrudes into the limit hole. The automatic unlocking device is mainly used for the cash register box in which the drawer can be automatically opened.
