4results about How to "Does not affect disassembly" patented technology

This utility model relates to the field of plastic processing machinery, specifically disclosing a moving mold, a fixed mold plate tie rod, and a material discharge protection device. It includes a moving mold plate, four tie rods, a fixed mold plate, a machine body, and a material discharge ramp. It also includes four tie rod protection fixing plates and four tie rod protection adjusting plates. The four tie rod protection fixing plates are symmetrically fixed and installed in pairs below the moving and fixed mold plates on opposite sides, with two of the two plates in each pair positioned above the two tie rods distributed front and rear below. The four tie rod protection adjusting plates are slidably connected to one of the tie rod protection fixing plates. This device effectively prevents oil stains from contaminating the ejected product, reduces manual cleaning costs, and improves production efficiency. The protection range is adaptable to molds of different thicknesses and various products. Installation and disassembly are convenient and do not affect mold assembly or disassembly. It also blocks dust and impurities to reduce tie rod wear.

This utility model relates to the field of steam turbine technology, specifically to a fir-tree type blade root structure, blades, and a steam turbine. The fir-tree type blade root structure provided by this utility model includes a blade root with a first side and a second side arranged opposite to each other. The first side is located on the back arc side of the blade root, and the second side is located on the inner arc side of the blade root. The second side has a protruding structure, and the first side has grooves corresponding to the protruding structures. The blade roots of each pair of adjacent blades interlock through the protruding and groove structures. The interlocking of the blade roots between each pair of blades, through the protruding and groove structures, allows the blade roots to mutually restrain each other during operation, limiting the circumferential sway range of the blades, thereby solving the problem of blade swaying due to low centrifugal force when the blades are lightweight or operate at low speeds.

The utility model relates to the technical field of submersible sewage pumps, and discloses a sludge treatment submersible sewage pump which comprises a main body assembly and a sewage pump body, a base is fixed to one side of the sewage pump body, a communicating pipe is fixed to one side of the sewage pump body, and a first clamping plate is connected to one side of the communicating pipe through a bolt; the base comprises a second clamping plate arranged on one side of the first clamping plate; the sealing assembly is arranged on one side of the first clamping plate and comprises a sealing piece, an auxiliary piece is arranged on the sealing piece, and the sealing piece comprises a fixing ring fixed to one side of the first clamping plate. The coupling device has the advantages that by additionally arranging the sealing structure on one side, when the sewage pump is coupled with the base, the additional sealing ring enters the through hole in the base and forms double sealing with the original rubber sealing piece of the coupling device, and meanwhile when the sewage pump is separated from the base, the sealing ring retreats back to the through hole of the drainage pump, equipment disassembly is not affected, and the service life of the drainage pump is prolonged. Therefore, the sealing reliability of connection is improved.

The utility model belongs to gear box technical field especially a kind of horizontal gear box, including box, gear shift mechanism is arranged in the inside of box, gear shift mechanism includes shift fork and gear set, the lifting of the shift fork is lifted and gear set is lifted, setting ventilation mechanism, the air that enters the inside of box is filtered, ventilation hole is set up in the outer surface of box, realizes ventilation, filter tube and ventilation hole sliding connection, its fixed while not affecting the disassembly of filter tube, vibration sensor real-time monitoring the vibration condition of gear box, temperature sensor real-time monitoring gear box internal temperature, the model of alarm can adopt LK-100 hand alarm, when vibration sensor or temperature sensor detects anomaly, triggers alarm to send sound and light signal.
