The utility model relates to a kind of installation tolerance regulators of automobile outer door handle, including assembly shell structure and multiple movable installation limiting components, assembly shell structure includes main connection shell, limiting handle corresponding slot area, multiple equidivided installation sleeve structure, movable installation limiting component includes mounting spiral sleeve structure and assembly adjusting bolt body, mounting spiral sleeve structure includes spiral sleeve body, spiral body being arranged on the outer surface of spiral sleeve body, limiting clamping groove, built-in limiting structure being arranged in spiral sleeve body, the assembly adjusting bolt body includes lock nut and nut and threaded body.The positioning structure of the installation tolerance regulator configuration is relatively simple, corresponding adaptability is strong, there may be size or space difference and low structural rigidity in multiple screwing components, locking firmness is poor, the two components of the body reduce forced misregistration after mounting screw locking, cause the two components of the body in Y direction stress opposite, cause partial torsion.

The utility model discloses a dustproof sludge outlet, which belongs to the technical field of sludge treatment and comprises a discharge pipe, a steel plate frame is arranged at the upper end of the discharge pipe, a discharge hole is formed in the discharge pipe, a discharge pipe is arranged at one end, far away from the steel plate frame, of the discharge hole, and filtering anti-blocking components are arranged on two sides of the discharge pipe. A dust suction pipe is arranged on one side of the filtering anti-blocking assembly, a collecting cover is installed on the surface of the bottom end of the discharging pipe, and a positioning installation assembly is arranged at the position, corresponding to the collecting cover, of the bottom end of the filtering anti-blocking assembly. By arranging the filtering anti-blocking assembly, flying dust generated when sludge is discharged can be collected, the flying dust is prevented from polluting the working environment, human health is guaranteed, meanwhile, the porous collecting frame can be conveniently disassembled, assembled and cleaned, a dust suction pipe is prevented from being blocked, the working stability of equipment is guaranteed, and the working quality is improved; the collecting cover can be conveniently and accurately mounted, so that raised dust generated by sludge discharge can be shielded.

This invention provides a spring outer circle grinding device, including a grinding box. A set of first cylinders is located on the top of the grinding box, with the output end of each cylinder extending into the grinding box. An upper positioning mechanism is fixedly connected to the output end of the first cylinders. A set of second cylinders is located on the right end face of the grinding box, with the output end of each second cylinder extending into the grinding box. A side positioning mechanism is installed at the output end of the second cylinders. This invention utilizes multiple upper positioning rollers rotatably connected between arc-shaped plates at both ends of the bottom of a first U-shaped frame and side positioning rollers rotatably connected between second U-shaped frames, along with grinding rollers rotatably connected to a support, to form a three-point positioning structure. The inscribed circle of each of these three points is the circumscribed circle of the spring to be ground. The positioning structure of the spring to be ground is simple, low in cost, and easy to promote.

The utility model discloses an electric ceramic cooker which comprises a bottom shell, an upper cover and a heating disc. The upper cover is arranged at the top of the bottom shell; a plurality of positioning columns are distributed on the inner bottom wall of the bottom shell in an annular array mode. The outer side of the positioning column is sleeved with a spring. The outer side of the heating disc is sleeved with a shell. A plurality of bearing lugs are arranged on the outer side surface of the shell; the number of the bearing lugs is the same as that of the positioning columns, and the bearing lugs and the positioning columns are arranged in a one-to-one correspondence mode. Positioning holes are formed in the bearing lugs; the positioning columns are arranged in the corresponding positioning holes in a penetrating manner; the bearing lug is positioned above the spring; the bearing lugs and the shell are of an integrated structure.
