The utility model discloses an engine cleaning machine with fixed-point positioning function, including the water tank structure of installation in the upper part of equipment outer box and the arc movement structure of realizing shower nozzle arc movement, the utility model discloses when washing engine, the shower nozzle is fixed in the through -hole of connecting pipe, through the drive motor drive swash plate rotation, make first slide bar in the slide rail of swing rod surface sliding, simultaneously pull the connecting plate inside swing rod in the upper portion of equipment outer box and carry out the swing of arc trajectory, simultaneously swing rod pull second slide bar and make the slider in the inside left and right swing of T type groove, simultaneously drive the synchronous sliding of upper slide and water storage tank to the high pressure spray cleaning of different position of engine surface to the shower nozzle, realize the multi -angle, all -round cleaning of shower nozzle, effectively solved the problem of dead angle in traditional cleaning mode, improved the efficiency and the cleanliness of engine cleaning.

The utility model relates to the technical field of bypass valve testing, in particular to a bypass valve opening pressure testing device which comprises an air compressor fixedly installed on the top of a bottom plate, a water tank fixedly installed on the top of the bottom plate, and an air storage tank fixedly installed on the top of the bottom plate. The air storage tank is located between the air compressor and the water tank, a testing groove is fixedly installed on the top of the water tank, and a testing seat is fixedly installed on the inner side of the testing groove. The electric telescopic rod drives the top seat to clamp the to-be-tested bypass valve assembly at a position between the test seat and the top seat, so that the to-be-tested bypass valve assembly is fixed and clamped conveniently, and water is pumped into the test groove through the submersible pump and the water outlet head to submerge the interface position of the to-be-tested bypass valve assembly. The air tightness of the to-be-tested bypass valve assembly is judged and tested by observing bubbles on the water surface, and the problem can be quickly judged according to the position of the discharged bubbles, so that the testing accuracy of the testing device is improved.

The utility model relates to pipeline connection technical field, and disclose a kind of pipeline connection assembly structure for pipeline fitting, including first installation ring, the middle threaded connection of first installation ring inner wall has threaded rod, the bottom end fixedly connected with handle of threaded rod.This pipeline connection assembly structure for pipeline fitting, through the mutual cooperation of handle, threaded rod, bearing, crosspiece, limit block, rubber pad and telescopic rod of being set, to realize the effect of the fixed pipeline, by rotating handle to drive the rotation of threaded rod, to drive the rotation of bearing, to facilitate the up-down movement of crosspiece, to drive the telescopic of telescopic rod, to facilitate the limit block to be moved to the outer side wall of pipeline, to facilitate the fixed clamping of pipeline, by rubber pad to increase the friction between pipeline, to be fixed as much as possible more fastening, to avoid the risk of pipeline falling during work as much as possible.

The utility model discloses a timber fixing device for wood bed processing, which comprises a bottom plate, the inner wall of the bottom plate is fixedly connected with two first bearings, the inner ring of one first bearing is fixedly connected with a rotating column, the inner ring of the other first bearing is fixedly connected with a rotating rod, and one end of the rotating column close to the rotating rod is fixedly connected with a connecting plate. The right side face of the connecting plate is fixedly connected with two fixing columns, the ends, away from the connecting plate, of the two fixing columns and the ends, close to the rotating columns, of the rotating rods are fixedly connected with fixing clamping plates, and the inner wall of each fixing clamping plate is in threaded connection with two threaded rods. Through mutual cooperation of the rotating column, the first bearing, the rotating rod, the connecting plate and the fixing column, wood plates can be turned over conveniently, workers can machine the wood plates conveniently, the using effect of the device is enhanced, the situation that wood needing to be machined is inconvenient to turn over can be effectively avoided, and the machining efficiency is improved. And the wood processing efficiency is reduced.
