2results about How to "Limit deflection" 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 relates to the technical field of faucets, and provides a waterway lifting combined core body and a faucet assembly with the combined core body, which are used for solving the problems of inconvenience in assembly and poor sealing performance in the prior art, and comprise a shell and an inner core body, a water inlet pipeline is arranged at the lower end part of the inner core body, and a valve core mounting cavity is arranged at the upper end part of the inner core body; a water way lifting groove is formed in one side of the outer wall of the upper end of the inner core body in the longitudinal direction, a water outlet communicating with the water way lifting groove is formed in the bottom of the groove bottom of the water way lifting groove, a horizontal channel is arranged between the water outlet and a water outlet hole in the bottom face of the valve element installation cavity in a communicating mode, and an annular sealing groove is formed in the peripheral side of the water way lifting groove. A split section is arranged on the upper end portion of the inner core body in an outward and downward inclined mode from the top of the inner core body, the split section splits the other side, located on the waterway lifting groove, of the upper end portion of the inner core body to form a split block convenient to install, and the split section passes through the bottom face of the valve element installation cavity, so that a limiting plane is formed on the inner side of the upper end portion of the split block convenient to install.
