Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.The example of these preferred implementations illustrates in the accompanying drawings.Shown in accompanying drawing and the mode of execution of the present utility model described with reference to the accompanying drawings be only exemplary, and the utility model is not limited to these mode of executions.
At this, also it should be noted that, in order to avoid the utility model fuzzy because of unnecessary details, illustrate only in the accompanying drawings with according to the closely-related structure of scheme of the present utility model and/or treatment step, and eliminate other details little with the utility model relation.
Shown in ginseng Fig. 1 and Fig. 2, a kind of removable Dogbolt, comprise: bolt body 1, described bolt body 1 comprises bolt head 2 and bolt shank 3, the conduit 4 along the axial arranging of bolt shank 3 is provided with in described bolt shank 3, be provided with the opening 5 communicated with conduit 4 in described bolt head 2, the cell wall 6 being positioned at bolt shank conduit 4 is convexly equipped with protuberance 7 to conduit 4, and described protuberance 7 arranges ringwise and is positioned at the neutral position of bolt shank 3.In described conduit 4, mandrel 8 is installed, expansion set 9 is provided with between described mandrel 8 and bolt body 1, the head 10 of described expansion set 9 is conically arranged, the head 10 of described expansion set 9 abuts against with the protuberance 7 in bolt shank conduit 4, described mandrel 8 comprises polished rod section 11 and thread section 12, the polished rod section 11 of described mandrel 8 comprises the first polished rod portion 13 and the second polished rod portion 14, conical transition portion 15 is provided with between described first polished rod portion 13 and the second polished rod portion 14, the diameter in described first polished rod portion 13 is greater than the diameter in the second polished rod portion 14, second polished rod portion 14 of described mandrel 8 with thread section 12 in being disposed adjacent.Described expansion set 9 is installed on the outside in mandrel second polished rod portion 14.Described thread section 12 is arranged in the opening 5 of bolt head 2, described mandrel thread section 12 is provided with nut 16, described bolt head 2 is provided with the several Cock screws 17 matched with nut 16, in the present embodiment, the quantity of described Cock screw 17 is preferably three, and three Cock screws 17 are evenly distributed on bolt head 2.Described bolt shank 3 is provided with the long strip groove 18 of the axial arranging along bolt shank 3.
