Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1-2, a kind of antirust screw of the utility model, comprises nail body 1 and the head of a nail 2, on described nail body 1, is provided with screw thread 8; The edge of described nail body 1 is provided with the first oil duct 3 for oil in reserve; One end of described nail body 1 is connected with the head of a nail 2, and the other end of nail body 1 is provided with annular groove 4; One end of described annular groove 4 is provided with block 5, and block 5 is fixedly connected with annular groove 4; On described annular groove 4, be provided with jump ring 7, described jump ring 7 is flexibly connected with annular groove 4; Described head of a nail inside is provided with the second oil duct 9; One end of the second described oil duct 9 is connected with the first oil duct 3; The other end of described the second oil duct 9 is provided with plug cock 6.
Further, described annular groove 4 and block 5 are all cylindrical bodys.
Further, the diameter of described annular groove 4 is less than the diameter of block 5.
When screw is in running order, jump ring 7 snaps in annular groove 4, prevents that in machine running process, generation is vibrated and comes off; Use oil nozzle in the 3rd oil duct 3, to add machinery oil by the second oil duct 9, then seal the second oil duct 9 with plug cock 6, can effectively prevent from getting rusty like this.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
