The head gasket is disposed between the cylinder head and the cylinder block and is structured to engage with the plurality of bite rings. The cylinder head may further include an expansion groove that is disposed between adjacent ones of the plurality of bite rings and extends in a circumferential direction around the cylinder head.

The utility model relates to a novel waterproof detachable plug-pull type connecting structure which comprises a handle rod and a handle plug-pull matching screw which are both of a hollow structure, and further comprises a female head gasket, a female head, a male head cushion block and a male head. Three grooves are formed in the lower end of the handle rod from top to bottom along the circumference and correspondingly provided with a straight-down hand-screwing nut, a clamping spring and a handle rod sealing ring respectively, meanwhile, a female head mounting groove is formed in the handle rod, a female head gasket, a female head, a bolt sealing gasket and a bolt are installed, and a male head mounting groove is formed in the handle insertion and extraction matching screw. And the handle rod is screwed through the straight down hand-screwing nut and is matched with the thread of the handle pull-plug matching screw to extrude the handle rod sealing ring, so that the handle rod is connected with the straight down hand-screwing nut in a sealing manner. The device is convenient to disassemble and assemble, seawater corrosion is effectively prevented, the 80-meter deep-sea sealing waterproof function is achieved, and the technical contradiction that a traditional integrated structure cannot give consideration to portability and deep-sea sealing at the same time is solved.

The application discloses a kind of preventing long string end head skin deformation method and end head gasket forming method in the technical field of composite material manufacturing process, comprising the following steps: long string is placed in the forming recess in the upper surface of forming curing tool;Place core mold;End head gasket is placed in the gasket groove in the upper surface of forming curing tool, and the gasket groove is vertically communicated with forming recess, and the end head gasket ballast is fixed above core mold;Skin is laid on the upper surface of forming curing tool, and the end of the skin is on end head gasket;Curing is carried out.The application carries out vertical rigid support to skin by end head gasket, not only can reduce the influence of uneven pressure on skin, thereby preventing skin deformation, but also simple operation, strong practicality.

The application discloses a method for saving activated carbon and porcelain rings in a lower head of a converter in production of calcium carbide method polyvinyl chloride, and belongs to the technical field of polyvinyl chloride production, and comprises the following steps: S1, horizontally welding a support frame in a straight cylinder section of the lower head of the converter; S2, laying a steel grating on the support frame, laying a steel wire mesh on the steel grating, and fixing the steel wire mesh to the steel grating by iron wires; the support frame is horizontally welded in the straight cylinder section of the lower head of the converter, the steel grating is laid on the support frame, the steel wire mesh is laid on the steel grating, and the steel wire mesh is fixed to the steel grating by the iron wires; the glass silk cloth I is laid on the steel wire mesh through edge pressing, the lower head gasket is placed on the pressing surface of the lower head, the activated carbon is laid on the glass silk cloth I, the glass silk cloth II is laid on the activated carbon, the filling of the phi 50 porcelain ring and the phi 25 porcelain ring is cancelled, the filling amount of the activated carbon in the lower head of each converter is effectively reduced, the filling weight of the lower head of the converter is reduced, and the lifting and installation risk of the lower head of the converter is reduced.

The utility model discloses a coating die head gasket installing and positioning device, including: lower die head, upper die head and height adjustment subassembly, height adjustment subassembly includes fixed link, first recess, positive and negative motor, threaded lead screw and slider, the left surface of lower die head is fixedly connected with the fixed link, the upper surface of fixed link is fixedly connected with positive and negative motor, the threaded lead screw is fixed with the fixed link, and the threaded lead screw is fixed with the fixed link. The output end of the forward and reverse motor is fixedly connected with a threaded lead screw, the side surface of the threaded lead screw is in threaded connection with a sliding block, the right surface of the sliding block is fixedly connected with a lower die head, and a first fixing block is fixedly connected to the left surface of the lower die head. And it is ensured that the relative position precision of the upper die head and the lower die head is always kept in the moving process, then the installation position of the gasket is more accurate, the outer side of the gasket can be limited while the interior of the gasket is limited, and the position of the gasket is stable.

The utility model belongs to the technical field of hard disk repair, and particularly relates to a drawable hard disk magnetic head extractor which comprises a first fixing plate and a second fixing plate, the first fixing plate and the second fixing plate are fixedly connected through a first support and a second support, and the outer wall of the second support is rotatably connected with an annular plate. A first connecting plate is fixedly connected to the outer wall of the annular plate, a third mounting plate is slidably connected to the interior of the first connecting plate, a second connecting plate is fixedly connected to one side of the third mounting plate, and a magnetic head gasket is mounted on one side of the second connecting plate. Through the combined design of the fixing plate and the support, a stable operation platform is formed, potential damage caused by vibration and displacement can be effectively avoided when the magnetic head assembly is taken out, the operation flexibility is improved through the rotation design of the annular structure, the equipment can meet the specific requirements of different hard disk models and magnetic head positions, and the operation efficiency is improved. And the complexity and the time consumption of the adjustment process are reduced.
