The invention discloses a positioning placement device suitable for columnar and spherical parts. The positioning placement device comprises a baseplate frame, wherein foundation bolts are mounted at four corners of the baseplate frame in a penetrating manner; a group of rotating shafts are welded on the baseplate frame; the rotating shafts are in running fit with rotary bases; a group of bolt shafts are mounted at the outer edge of each rotary base in a penetrating manner and are in running fit with rollers; the rollers are in contact with the baseplate frame; an upright is welded with the upper part of each rotary base; a top frame is welded at the top of each upright; pin shaft rack are welded in two side positions of each top frame; the pin shaft racks are matched with rotating rollers through pin shafts; the rotating rollers are in running fit with the corresponding pin shafts; and a rotating shaft groove is formed in the bottom center of the each rotary base. The positioning placement device suitable for the columnar and spherical parts is simple in structure, low in production cost and reliable in positioning with the ground, can be used in group, meets the placement demands of the columnar parts, the spherical parts, and parts with conical faces, and satisfies the requirement for rotating the parts during detection.

The invention discloses a method and a device for mounting a lock on a transmission device body, and relates to the field of pneumatic pipeline transmission. In the prior transmission device, a lock is arranged on a cover; as the lock has a large structure and is quite inconvenient to operate. A lock mechanism is arranged on a transmission device main body; and the lock mechanism is arranged on the sidewall of the transmission main body.

The invention provides a backing preventing lock body mechanism and a touch type door lock and mainly solves the problem that most of the structures of the existing door lock backing preventing mechanisms are complicated. The touch type door lock is characterized in that a lock shell comprises an inner cavity and an opening which communicate with each other; a lock tongue is arranged in the innercavity and linearly moves for unlocking or locking, and when the lock tongue is located at a locking position, the front end of the lock tongue extends out of the opening and is exposed out of the lock shell; a blocking component comprises a first position at which the blocking component is driven by a rotating core to carry out blocking fit with the lock tongue when the lock tongue is at the locking position and a second position at which the blocking component moves away from the motion path of the lock tongue; and an elastic resetting component is used for pushing the rotating core and driving the blocking component to move towards the second position. According to the lock body mechanism and the touch type door lock, provided by the invention, the backing of the lock tongue is prevented through the motion of the blocking component, the structure is simple, and the use is convenient; and moreover, the touch type door lock provided with the mechanism is further provided, unlocking can be carried out through press rather than rotating, the structure is compact, and the demand on door opening space is low.

The invention discloses a resonance-peak-free vibration isolator of an L-shaped resistance arm, and a damping module of the resonance-peak-free vibration isolator. The resonance-peak-free vibration isolator consists of a vibration damping module, the damping module and a connection module, wherein the vibration damping module comprises a hollow internal thread hexagon bolt, an internal thread sleeve and a main spring; the damping module comprises a waist-drum-shaped damping sleeve, a first L-shaped damper, a second L-shaped damper and a damping module buffering spring; and the connection module comprises an upper end cap, a fastening pressure plate, a lower cover cap with a cylindrical bulge, and a base. The damping module disclosed by the invention is simple in implementation structure. When the vibration isolator vertically vibrates, the two L-shaped dampers in the damping module are respectively in contact with two concave ports, so that stable damping force in vertical and horizontal directions can be provided, good centering and resetting effects on transverse vibration can be realized, and the resonance inhibiting effect is good. The damping module disclosed by the invention is simple in implementation structure, and has a good inhibiting effect on transverse resonance and longitudinal resonance.

The invention discloses a small soil stirring device which is easy to clean, comprising a strip-shaped support frame, a stirring and cleaning mechanism is provided on the upper surface of the strip-shaped support frame, and a limiting support mechanism is provided on the lower surface of the strip-shaped support frame. The beneficial effect of the present invention is that it is a device that is more convenient to use, has a relatively simple structure, and is more uniform in stirring, and is also convenient for more effective cleaning of the stirring tool after stirring, reduces labor intensity, has good sealing contact with the ground, and is relatively convenient to carry .
