4results about How to "Improve replacement speed" patented technology

The utility model provides a back countersink. Comprising a cutter bar, one end of the cutter bar is provided with a connector, a limiting step is formed between the connector and a guide rod, and the connector is provided with a threaded hole and a pin hole A; reverse scrapers are arranged on the two opposite outer walls of the tool bit, pin holes B perpendicular to the reverse scrapers are further formed in the tool bit, and the tool bit is axially connected with the connector and limited through a limiting step. The steel ball screw is screwed into the threaded hole, and a movable steel ball is arranged at the front end of the steel ball screw; the locking pin sequentially penetrates through the pin hole A and the pin hole B, and an arc groove is formed in the middle of the locking pin and makes contact with a steel ball of the steel ball screw. Through the cooperation of the limiting screw and the locking pin, when the cutter is replaced, only the locking screw needs to be loosened, and the replacement speed is increased; the reverse scraper is in contact with the inclined surface of the tool bit, so that the contact area of the reverse scraper and the tool bit is increased, and the strength of the tool bit is improved.

The invention provides a modular vegetation base material structure for subsidence area abrupt slope repair, and relates to the technical field of subsidence area abrupt slope repair, the modular vegetation base material structure comprises an abrupt slope repair unit, a protection detection unit, an elastic connection unit and a multipurpose limiting unit; the protection detection unit is mounted on the abrupt slope repair unit; the number of the elastic connecting units is four, and the four elastic connecting units are installed on the abrupt slope repairing unit. The number of the multipurpose limiting units is four, the four multipurpose limiting units are installed on the abrupt slope repairing unit, and the multipurpose limiting units are used for limiting the abrupt slope repairing unit. According to the device, a worker can conveniently connect the adjacent abrupt slope repairing frames through the circular connecting shaft, the annular positioning block a and the annular positioning block b, and rapid assembly of the adjacent abrupt slope repairing frames is achieved; the problems that the connection efficiency is affected due to the fact that adjacent vegetation base material structures are connected through bolts generally, and when the vegetation base material structures need to be subjected to angle change, workers cannot control the connection tightness conveniently are solved.

The utility model discloses a kind of spray pipe structures of cloth bag dust collector, it is related to cloth bag dust collector technical field, to solve the current existing cloth bag dust collector's spray pipe structure's spray nozzle is easy to block technical problem, including spray pipe, the spray pipe one end is equipped with mounting bracket, several spray nozzles are installed in linear equidistance array on the spray pipe, the spray nozzle is communicated with spray pipe, mounting assembly is installed on the mounting bracket, several one-way blocking members are installed in linear equidistance array on the mounting assembly, the one-way blocking member can correspond with spray nozzle, the utility model is blocked with independent one-way blocking member in each spray nozzle, blow open dust removal when spraying, one-way blocking member is automatically blocked at spray nozzle to prevent dust backflow when not spraying, and one-way blocking member is independently installed on mounting assembly, and it is convenient to quickly disassemble, repair and replace.

The utility model relates to the technical field of UV printer ink supply, in particular to a UV printer ink supply device convenient to replace an ink cartridge, which comprises a positioning plate and a box cover, the positioning plate is provided with a positioning mechanism with a function of limiting the movement of a box body by a loop bar, the positioning mechanism comprises a sleeve, and the sleeve is in interference fit with the loop bar. A sleeve rod and a sleeve in the positioning mechanism are matched to enable a triangular positioning plate to keep a horizontal state and a movable state, when the triangular positioning plate makes contact with the ink box, the sleeve rod slides into the sleeve, a spring is squeezed by the triangular positioning plate to be compressed, and at the moment, the ink box can be taken out upwards; the triangular positioning plate can be driven to be clamped into the inclined groove and lock the ink box through rebounding of the spring, through the design of the positioning mechanism, the advantages of rapid automatic locking and rapid unlocking of the ink box are achieved, meanwhile, the speed of replacing the ink box is increased, and the replacing steps of the ink box are simplified.
