4results about How to "Prevent automatic reset" patented technology

This invention relates to the field of robotic welding technology, specifically to a self-resetting welding device and method. The self-resetting welding device includes: a housing assembly having at least one opening; a tilting assembly located within the housing assembly, at least a portion of which is rotatable relative to the housing assembly; the tilting assembly is detachably connected to the housing assembly; a welding assembly extending axially, at least a portion of which is located within the housing assembly; wherein the tilting assembly is sleeved on at least a portion of the welding assembly; a first reset assembly, with both ends perpendicularly connected to at least a portion of the tilting assembly and the housing assembly, respectively; and a protective assembly disposed on the outer periphery of the housing assembly and extending radially to cover the opening; the protective assembly and the first reset assembly extending radially and spaced axially by a predetermined distance. This addresses the problem of how to rationally arrange the reset assembly and the protective assembly to avoid mutual interference while simultaneously achieving dual protection of the welding assembly's reset and internal safeguards.

This utility model discloses an experimental device for measuring the starting pressure gradient of pulverized coal, relating to the technical field of pulverized coal measuring devices. It includes a storage tank, a feed pipe, an air inlet pipe, a connecting box, a support frame, and an air compressor. The output end of the air compressor is fixedly connected to the connecting box via an air delivery pipe. The connecting box is equipped with a locking mechanism for locking and maintaining the detected data. Through this locking mechanism, this utility model can automatically detect and lock the steadily rising pressure value in the storage tank and the inner cavity of the air inlet pipe during the pressurization of pulverized coal, effectively preventing the detected pressure value from automatically resetting during depressurization. This facilitates maintaining and recording the pressure value under the corresponding state, thereby ensuring the stability and traceability of the pressure data. By conveniently unlocking, the starting pressure gradient of pulverized coal can be remeasured based on the new pressure value, further improving the accuracy and reliability of the measurement.

The utility model discloses a varicose vein rehabilitation training device for blood vessel surgery relates to training equipment technical field, including main part, installation frame, massage piece and support spring, one side of main part is provided with installation frame symmetry, the inside rotation of installation frame is connected with massage piece, the utility model discloses be provided with adjusting mechanism and governing mechanism, because the mounting bracket is linked with the rotating plate through the connecting plate, and the mounting bracket is slidably connected with the main part through the movable slot, so that in the process of rotating the handle, rotating shaft and rotating plate, the connecting plate can drive the mounting bracket to move horizontally, thereby realizing the adjustment of the spacing between the two installation frames, and the hinged frame is horizontally moved and the support spring is kept in the required state by rotating the threaded rod, so as to be adapted to the installation frame after adjustment, so that the training device can be suitable for people of different body types, and the adaptability is improved.

The application discloses a dustproof deep-groove ball bearing, which comprises a bearing outer ring, a bearing inner ring and balls, the bearing outer ring is coaxially sleeved on the bearing inner ring, the balls are arranged between the bearing outer ring and the bearing inner ring, both ends of the bearing outer ring are provided with sealing cover plates, a sealing element is arranged between the bearing outer ring and the bearing inner ring, the sealing element is located between two adjacent balls, end faces of the two sealing cover plates are arranged on the sealing element, sealing grooves extending along the grooves are formed in the inner side wall of the bearing outer ring and the outer side wall of the bearing inner ring, and a limiting block is arranged on a radial side of the sealing element and slidably arranged in the sealing groove. The double-face sealing structure is adopted to form two dustproof barriers, the sealing element is stable in installation and does not affect the operation of the bearing, the sealing cover plates can be disassembled and replaced with lubricating grease, the problems that the traditional bearing has poor dustproof effect and the solidified lubricating grease is difficult to replace are solved, and the operation stability and service life of the bearing are improved.
