The invention relates to a permanent magnet speed regulator with a fixed magnetic gap, and the speed regulator comprises a first internal magnetic rotor, a second internal magnetic rotor, and an external magnet rotor frame, wherein a driving shaft coaxially passes through the first and second internal magnetic rotors, and the external magnet rotor frame is connected with a driven shaft. The external magnet rotor frame is provided with an external magnetic rotor through a bearing. In addition, one end, close to the driven shaft, of the external magnetic rotor is provided with an external magnetic rotor planetary gear. A driven shaft planetary gear is disposed between the external magnetic rotor planetary gear and the driven shaft. The speed regulator employs a fixed magnetic gap structure, so the speed regulator greatly increases the engagement area, reduces the assembly difficulty, reduces the generated heat, enlarges the range of speed regulation, saves rare earth materials, and greatly improves the capability of torque transmission. Because the speed regulator employs a planetary gear transmission structure, the speed regulator achieves a function of 0-%N speed regulation of input and output rotating speeds through changing the gear ratio of the external magnetic rotor planetary gear to the driven shaft planetary gear. In addition, the speed regulator employs a bearing structure, and prevents the continuous shaking of the driven shaft in two directions from causing that the driven shaft cannot rotate normally in one direction to drive a load.

The invention provides a four-link tension string for a + / -800KV heavy ice area, belonging to fitting strings for construction of transmission lines. The four-link tension string comprises two hanging point fittings connected with a tower, wherein after being connected with the same fitting, each hanging point fitting is connected at the left end of a first yoke plate by a bolt; the right end of the first yoke plate is connected with two insulators by a ball head hanging ring; two of the four insulators are connected on a second yoke plate and the other two insulators are connected on the other second yoke plate; the two second yoke plates are respectively connected with a combined yoke plate by a right-angle hung plate; an equalizing ring is arranged on two insulators; the equalizing ring is in open type or two-leg split type; the combined yoke plate is formed by connecting a two-variable four-link plate, two right-angle hung plates and two one-variable two-link plates by bolts; and two shielding rings are fixed at the upper and lower ends of the two-variable four-link plate by brackets. The four-link tension string has the characteristics of convenience for installation of the equalizing ring, stable structure and high strength.

The invention discloses a kitchen cabinet comprising a cabinet body, side plates and end strips. The side plates are disposed on the sides of the cabinet body. The end strips are disposed at the front ends of the side plates. The end of each end strip, close to the cabinet body, is level to the inner sides of the side plates. The kitchen cabinet has the advantages that the end strips are disposed at the front ends of the side plates, the ends of the end strips, close to the cabinet body, are level to the inner sides of the side plates, and accordingly the kitchen cabinet is attractive and neat in appearance; the end strips and the side plates can be produced industrially, product precision is high, product quality is high, field installation and construction are convenient, and the requirements on the skill of workers are low; the end strips are very convenient to detach, and the kitchen cabinet is easy to maintain.
