The invention discloses a power distribution cabinet having a shockproof function. The power distribution cabinet comprises a base body, wherein a first groove is formed in a middle part of an upper surface of the base body, two roller grooves are symmetrically formed in an inner side wall of the first groove, a fixed plate is arranged in the first groove, a power distribution cabinet body is arranged on the upper surface of the fixed plate, fixed blocks are fixedly connected to a left side surface and a right side surface of the fixed plate, ends, far away from each other, of the two fixed blocks penetrate through the first groove and respectively extend to the two roller grooves, back surfaces of the two fixed blocks are fixedly hinged with rollers via pin shafts, the rollers are clampedto the roller grooves, and two second grooves are symmetrically formed in an inner bottom wall of the first groove. By the power distribution cabinet having the shockproof function, the effect that the fixed plate moves upwards and downwards is achieved, the function of reducing vibration of the power distribution cabinet body is possessed, the problem that a traditional power distribution cabinet is not possessed with the shockproof function is solved, and damage to the interior of the power distribution cabinet body during swinging at a bumpy road is prevented.

An artificial joint member made of a polymeric material including a portion made of a polymeric substance has a sliding surface composed of a polymer having phosphoryl choline groups. With such an arrangement, the artificial joint member is provided with a sliding part capable of keeping a satisfactory lubricating state for a long time.

The invention provides an automobile manual variable speed controller capable of absorbing shock. The automobile manual variable speed controller capable of absorbing shock is characterized in that the automobile manual variable speed controller is a combined swing arm composed of a main swing arm body and an auxiliary swing arm body, the main swing arm body is installed at the center of a disc-shaped base, the auxiliary swing arm body is installed at the lower end of the main swing arm body, the main swing arm body comprises a control lever, first bearing holders, second bearing holders, first inner bearing sleeves, second inner bearing sleeves, springs, steel balls with holes and bearing gaskets, buffer plates are vertically and fixedly connected to the position of the center of the disc-shaped base after being attached to the upper ends of the bearing gaskets, the lower end of the control lever is connected with the auxiliary swing arm through a connecting part, and a first installation positioning sleeve and a second installation positioning sleeve which are arranged on the two sides of the auxiliary swing arm body enable the shaking amount of the auxiliary swing arm body to be constant; during gear selecting and shifting movements, the main swing arm body swings to transmit kinetic energy to the auxiliary swing arm body so as to achieve gear selecting and shifting movements, and the auxiliary swing arm body swings in a front-and-back mode to achieve the shock absorption function. The automobile manual variable speed controller solves the problems that when a manual vehicle runs on a step road, the spontaneous out-of-gear phenomenon is prone to occurring and a control handle shakes sharply.

A vertical force-measuring bridge bearing and its force-measuring method, through the measurement of local force and overall calibration, the overall force of the bearing is determined, the structure is simple, the increase in size and weight is small, the force measurement is reliable, and the bridge support can be realized The vertical force measurement function of the support can solve the problem of vertical force measurement of the support and provide technical support for bridge monitoring.
