The utility model provides a kind of auxiliary device for special equipment detection, for the detection of dangerous chemical tank, comprising: base, for installing lifting mechanism and bearing mechanism;Bearing mechanism, bearing disc is rotatably arranged on the upper end of base by bearing ring around the central axis of disc body, and the upper end of disc body is centrally supported to be detected dangerous chemical tank;Clamping mechanism, hoist by the rotating disc of rotating mechanism, and is symmetrically clamped on the outer peripheral wall upper portion of dangerous chemical tank by a pair of clamping blocks;Rotating mechanism, for hoisting clamping mechanism and for driving clamping mechanism and the dangerous chemical tank clamped by clamping mechanism around rotary shaft synchronous rotation, rotary shaft is located in the center of bearing disc directly above;Lifting mechanism, installed on the upper end of base, hoist rotating mechanism by lifting plate, for driving rotating mechanism and the clamping mechanism hoisted on rotating mechanism synchronous lifting.The utility model can stably carry dangerous chemical tank, as the temporary detection platform of dangerous chemical tank, the performance of auxiliary dangerous chemical tank detection operation.

The utility model relates to the technical field of supporting bases, in particular to an improved supporting base which comprises a cover plate, an upper fixing frame and a lower fixing frame, four sets of first nuts are arranged on the cover plate, the cover plate is detachably installed at the top end of the upper fixing frame through the four sets of first nuts, and the upper fixing frame is located above the lower fixing frame. And four groups of second nuts are arranged on the lower fixing frame. When the environment where the supporting base is located shakes, the compression-resistant ball can move between the upper arc disc and the lower arc disc through inertia, at the moment, the upper fixing frame can generate displacement opposite to the shaking direction relative to the lower fixing frame, shaking energy is consumed, shaking of the upper fixing frame is reduced, and the service life of the supporting base is prolonged. And by arranging the soft springs, part of shaking energy of the upper fixing frame can be absorbed and consumed, so that shaking of the upper fixing frame is further reduced, and then the stability of the whole supporting base is improved.

The utility model discloses a vehicle-mounted support which comprises a base, a clamping seat and a clamping arm, the clamping seat is rotatably connected to the base through a damping pivot, and can rotate up and down relative to the base; the clamping arm is rotatably connected to the clamping seat and forms a clamping cavity with adjustable opening and closing degree, the rotary connection structure between the clamping arm and the clamping seat comprises an elastic member, and the elastic member always drives the clamping arm to rotate in the direction of reducing the opening and closing degree of the clamping cavity; the utility model utilizes the damping pivot between the clamping seat and the base to adjust the up and down rotation angle of the clamping seat relative to the base, and meets the different visual angle requirements of users. With the rotary connection between the clamping arm and the clamping seat, and through the elastic member always driving the clamping arm to rotate in the direction of reducing the opening and closing degree of the clamping cavity, stable clamping force is ensured for the mobile phone. The utility model can meet the requirements of mobile phone navigation visual angle adjustment, convenient operation and safe use during driving, and effectively improves the convenience and safety during driving.
