Magneto-rheological shock absorber with multiple guiding functions
PendingCN119554362Areduce frictionIncrease guide lengthSpringsNon-rotating vibration suppressionMagneto rheologicalFriction force
The magneto-rheological shock absorber with the multiple guiding functions comprises a cylinder barrel assembly, a piston rod assembly, a guider assembly and a piston assembly, the guider assembly is arranged in the cylinder barrel assembly, the piston rod assembly comprises a piston rod, one end of the piston rod penetrates through the top end of the cylinder barrel assembly and the guider assembly to be connected with the piston assembly, and the other end of the piston rod penetrates through the cylinder barrel assembly and the guider assembly to be connected with the piston assembly. The guider assembly comprises a guider, a first guiding supporting piece and a second guiding supporting piece, the first guiding supporting piece and the second guiding supporting piece are arranged on the guider, the first guiding supporting piece and the second guiding supporting piece are vertically arranged in a spaced mode, the first guiding supporting piece is located at the upper end of the guider, and the second guiding supporting piece is located at the lower end of the guider. And a certain distance is formed between the two guide supporting pieces, so that double guidance is formed, the guide length is increased, the guidance quality is improved, the friction contact surface is not greatly increased, and the lateral force resistance and smaller friction force of the shock absorber are ensured.

A fixture for bonding and curing a canted reverse-thrust rocket nozzle
The application provides a tool for bonding and curing of a bevelled reverse thrust rocket nozzle, which comprises a fixing base and an upper pressing plate; the fixing base is used for fixing a nozzle shell so that a nozzle port of the nozzle shell is vertically arranged; the upper pressing plate is installed above the fixing base through a connecting piece; a threaded through hole is formed in the upper pressing plate and is arranged along an axis of a bonding surface of a throat liner and the nozzle shell; and a pressing assembly for pressing the throat liner against the nozzle shell is threadedly connected to the threaded through hole. The tool adopts a groove type design which is convenient for product installation; through coaxial screwing force acting on a bonding conical surface, the nozzle shell is bonded more conveniently and quickly; meanwhile, the upper and peripheral fields of view are not hindered, the bonding process is more clear and controllable, and the removal of excess overflow glue is more convenient than the existing bonding condition; assembly surface abrasion is avoided; the nozzle bonding quality is obviously improved; and the tool is suitable for bonding and curing of most special-shaped bevelled reverse thrust rocket nozzles.

Error-proof connector for automobile wire harness
ActiveCN222282398Uavoid misalignmentEasy alignmentCoupling device detailsStructural engineeringMechanical engineering
The utility model provides an automobile wire harness mistake-proofing connector, and belongs to the technical field of automobile wire harness connectors. The tail end of the plug connector is inserted into the bayonet socket; the number of the sliding type mistake-proof connecting assemblies is two. The two sliding type mistake-proof connecting assemblies are symmetrically assembled on the outer walls of the bayonet socket and the plug connector; the movable part of the sliding type mistake-proof connecting assembly slides along the connecting direction of the bayonet socket and the plug connector; according to the device, before the plug connector is inserted into the bayonet socket, the plug connector is guided through the sliding type mistake-proof connecting assembly, the plug connector is accurately inserted into the bayonet socket through guiding of the sliding type mistake-proof connecting assembly, and the situation that the plug connector and the plug connector are staggered during connection is avoided; when the sliding type mistake-proof connecting assembly is used, the strip-shaped sliding block extends out by a certain distance in a sliding mode, the guiding length is prolonged, alignment of the strip-shaped sliding block and the mistake-proof connecting groove is facilitated, and the sliding type mistake-proof connecting assembly can be conveniently used in the environment with narrow operation space and limited view.
