The spring groove is equipped with a compression spring. The inner end of the compression spring is connected to the retainer body. The outer end of the compression spring is exposed from the opening end of the spring groove and pushed Hold the wedges so that they remain snug against the outer and inner rings at all times. The invention does not affect the normal operation of the wedge and has the ability to prevent the reverse assembly of the wedge, improves the processing efficiency of the product, ensures the quality of the product, and reduces the production cost.

The invention, which relates to the technical field of motor rotor assembling, discloses a multi-directional automatic magnetic steel guiding device comprising a pedestal and a substrate. A magnetic steel guiding positioning seat is arranged at the center of the top surface of the substrate; feeding channels are formed in four side surfaces of the magnetic steel guiding positioning seat; four feeding tracks are formed in the top surface of the substrate; and four magnetic steel guiding positioning slots that correspond to and are communicated with the inner ends of the feeding channels one by one are formed in the top surface of the magnetic steel guiding positioning seat. In addition, permanent magnet pieces are arranged inside the inner end surfaces of the feeding channels. A motor rotating shaft positioning sleeve is arranged at the center of the top surface of the magnetic steel guiding positioning seat. A cylinder with a shaft end upward is arranged at the center of the pedestal; a magnetic steel push-out sleeve is arranged at the shaft end of the cylinder; and the cross section of the magnetic steel push-out sleeve has a square annular shape. Besides, a rectangular avoidance hole is formed in the center of the bottom of the magnetic steel guiding positioning seat. The magnetic steel piece assembling efficiency is high; and neglected mounting or reverse mounting of a magnetic steel piece can be prevented effectively.

The invention relates to a reverse stop bearing with a self-locating fastening bearing retainer, which includes an outer ring, an inner ring, a retainer body, steel balls, wedges and a fixed cover, and the fixed cover is arranged between the first end of the outer ring and the inner ring. Between the first end of the ring, the wedge spacing boss is provided with a fastening hole, and the bottom of the fixed cover is provided with a fastening card that matches the fastening hole. It is connected with the retainer body by buckling in place; it is characterized in that: a fan-shaped guide groove is provided on the wedge spacer boss, the fastening hole is located at the apex of the fan-shaped guide groove, and the arc edge of the fan-shaped guide groove is located On the top end surface of the wedge spacer boss, the depth of the fan-shaped guide groove gradually increases from its arc edge to its apex, and the bottom surface of the fan-shaped guide groove is an inclined plane. The present invention has simple structure and ingenious design, no very precise alignment is needed when the fixed cover is snapped and connected with the retainer body, and meanwhile, it has the ability to prevent reverse assembly of wedges and improves the processing efficiency.

A lamp battery box comprises a frame body and a battery reverse-installation preventing device. The battery reverse-installation preventing device comprises a fixed shaft which is arranged on the frame body, a lever which is arranged on the fixed shaft in a penetrating manner, at least one positioning needle which is arranged on one side of the fixed shaft and a telescopic contact which is arranged on the lever; the positioning needle is inserted into a gap between two adjacent batteries; and the telescopic contact pushes against the side wall of the battery at a compression state. When a positive electrode and a negative electrode are reversely installed and a last battery is installed to facilitate the movement of a contact of the telescopic contact towards a clamping part, the positioning needle cannot be inserted into the gap between two adjacent batteries but pushes against the side wall of one battery, the contact of the telescopic contact cannot be ejected, and the installation of the last battery is stopped by the contact, so that the user can be reminded of the reverse installation of the batteries, and a purpose for preventing the reverse installation of the battery can be realized.

The invention provides a tire pressure sensor packaging lead frame which is used for being fixedly connected with a tire pressure sensor chip, a main control chip and a transmitting chip. The lead frame comprises a frame body which is made of nickel porpezite materials. The frame body comprises a first substrate, a second substrate, first pin wires and second pin wires. The first substrate and the second substrate are arranged in the center of the frame body. The first substrate is used for mounting the main control chip and the transmitting chip. A through hole is formed in the center of the second substrate and used for sensing the outside air pressure. The second substrate is used for fixing the tire pressure sensor. The first pin wires are in a T shape and are arranged on the opposite two sides of the first substrate. The second pin wires stretch and are distributed in the length direction of the side edge of the second substrate. The first pin wires and the second pin wires are used for transmitting signals of the main control chip, the transmitting chip and the tire pressure sensor to an external device respectively. The frame body is made of the nickel porpezite materials, and a later electroplating technology is omitted. Meanwhile, the lead frame has good electrical conductivity and thermal conductivity after the nickel porpezite materials are adopted.
