Structures such as a motor circuit are integrated and placed in the motor box, the integration level is high, and installation is convenient; the panel is a highlight panel, the sense of science and technology is high, and the overall appearance is simple and attractive.

The utility model relates to the field of nuts, in particular to a concave-convex type anti-slip locknut which comprises a nut main screw, a main body used for connecting the nut and a component, an upper wedging gasket and an embedded groove arranged outside the nut main screw and used for increasing torsion, and a fixing clamping groove is formed in the embedded groove. The concave-convex type nut is provided with the upper wedging gasket, the self-locking block, the first radial sawteeth, the lower wedging gasket and the second radial sawteeth, when the concave-convex type nut is used, after the main screw of the nut penetrates through the connecting position, the clamping design of the embedded groove in the upper wedging gasket and the self-locking block can provide additional locking force after the nut is screwed down, and therefore the locking effect of the nut is improved. And then the upper matching gasket and the lower matching gasket are matched with each other through the first radial sawteeth and the second radial sawteeth, so that the friction force between the nut and an object is increased, and the nut is further prevented from slipping.

The present application relates to a kind of multilayer constant force scroll spring and its production process, including several coil springs;Several described coil springs are successively stacked and are refuted into shape, and the two ends of coil spring are fixed respectively.The beneficial effects of the present application are that:1.thin single-layer coil spring is stacked after forming the constant force scroll spring with consistent bending radius, compared with directly using thicker spring, the forming method of the present application can make the scroll spring curl to small volume more, to realize the increase of its torsion in the case of not increasing or increasing less scroll spring volume, meet the industrial needs;2.the torsion of multiple times after stacking can be obtained after the two ends of single-layer coil spring with consistent inner diameter are fixed respectively, meet the requirement of increasing torsion.

The utility model relates to the technical field of torsion detection, and discloses an insertion barrel torsion detection device which comprises a base, a vertical plate is fixedly connected to the middle of the top face of the base, an inclined plate is fixedly connected to the top of the vertical plate through bolts, a fixing block is fixedly connected to the top face of the inclined plate, and a cushion block is fixedly connected to the top face of the fixing block. A positioning block is fixedly connected to the upper end of the top face of the inclined plate, a front insertion barrel is attached to the inner wall of the positioning block, a notch is formed in the lower end of the front insertion barrel, a rotating air cylinder is fixedly connected to the front side of the top face of the base, a clamping block is fixedly connected to one end of the rotating air cylinder, and a surrounding plate is fixedly connected to the edge of the top face of the base. According to the utility model, the insertion barrel is positioned and fixed by the positioning block, so that the notch is aligned with the clamping block to be clamped, the rotating cylinder is started, the clamping block is rotated, and whether the notch can tolerate enough torsion acting force or not is tested by increasing torsion force.

The application provides a rotating shaft mechanism, a foldable shell and a foldable electronic device. The rotating shaft mechanism comprises a base, a first rotating shaft assembly and a first elastic piece. The first rotating shaft assembly comprises a first rotating shaft, a first movable seat, a first connecting rod arm and a second connecting rod arm.
