2results about How to "Limit tilt" patented technology

This utility model relates to the field of electric motor technology, specifically disclosing a rack guide structure, including a guide sleeve with a guide channel. The cross-sectional shape of the guide channel is non-circular or non-arc, and the guide wall of the guide channel includes at least one planar segment. The guide channel is used to cooperate with an anti-rotation part on the rack. The cross-sectional shape of the anti-rotation part is adapted to the shape of the guide channel, allowing the rack to reciprocate along the guide channel. A pump electric motor includes a motor body, a gear, and a rack. The motor body drives the gear to rotate, and the rack meshes with the gear, serving as the reciprocating drive source for the pump body. It also includes the aforementioned rack guide structure. The guide sleeve in the rack guide structure is fixedly installed on the housing of the motor body, and the anti-rotation part of the rack cooperates with the guide channel of the guide sleeve. This solution addresses the problem of easy wear caused by rack deflection or tilting in current rack-output motors.

The utility model discloses a kind of durable corrugated box compression testing device, including bottom plate, the top side of bottom plate is equipped with long slot, long slot is cross-shaped, fixedly installed with placing plate in long slot, through the collaborative design of driving assembly, transmission assembly and clamping assembly, effectively solve the carton side fixed problem, motor as driving source, drive first bidirectional screw rod rotation, through the multistage transmission of first synchronous wheel, synchronous belt, second synchronous wheel, transmission rod, first bevel gear and second bevel gear, make first bidirectional screw rod and second bidirectional screw rod reverse rotation, since the thread rotation direction of two screw rods is opposite, the slider of its outside drives fixed rod and clamping plate synchronous to carton four sides and adhere, after clamping plate and carton side contact, limit the displacement of carton when testing, inclination, ensure that vertical pressure evenly conducts to carton surface, avoid the test force value deviation caused by side no constraint, improve the accuracy and reliability of test data.
