Abstract
The utility model relates to a cover screw cap, comprising a screw cap, a cover and a baffle. Plastic pads are arranged in the screw cap and on the cover. For the inclined head bolt, the plastic pad can not extend the action point of the acting force on the center of the cover, and the force bearing condition of the cover can be changed, which leads that the cover can not be opened in the stirring process. For the flat head bolt, the pad is crushed into pieces in the stirring process, and the pieces are collected to the center in the deformation process of the cover, which leads the action point of the acting force on the cover become smaller. And so, when the regulated torque is achieved, the cover can be successfully ejected off. The utility model can save a quantity of bolts and greatly improve working efficiency in the production.
Description
Technical field:
The utility model relates to a kind of nut, the particularly a kind of and matching used stifle nut of body of rod anchor pole.
Background technique:
At present supporting widely used anchor pole in down-hole comprises the body of rod and nut, and the body of rod is cylindrical, is convenient to rotation, fully stirs the anchoring agent for making the body of rod of inserting behind the anchor hole, and nut has increased stifle in design, forms the stifle nut.This stifle nut comprises nut, stifle and baffle plate, and baffle plate is arranged on the tail end of nut, and stifle is arranged on the nut afterbody and with the screw sealing of nut and by baffle plate it is tightened.During use, nut screws in the body of rod to the tail end of the body of rod and pushes up stifle, with the body of rod insert anchor hole, with after the bursting of anchoring agent container, with recessed machine rotation stifle nut, at this moment, because the effect of stifle, the body of rod can only rotate with nut and stir the anchoring agent, after stirring evenly, leaves standstill in required time, and then screw nut, at this moment, the body of rod is bonded on the crag and can not rotates by the anchoring agent, along with the increase of fastening force, the body of rod backs down stifle, continues rotation, finishes the fastening of anchor pole.There is following defective in this stifle nut at present in use, is the body of rod of angle to tail end, because body of rod tail end is not the center portion that withstands on stifle, when stirring the anchoring agent, the body of rod just usually pushes away stifle, cause anchor pole can't continue anchoring, cause anchor pole to be scrapped; And for flat mouthful the body of rod, then can be stressed too even because of stifle, after stirring, leave standstill operation and finishing, when recessed machine fastening nut reached prescribed torque, the stifle top was not fallen and is made the anchor pole can't anchoring, caused anchor pole discarded equally; Cause bigger manpower and physical waste.
Summary of the invention:
The purpose of this utility model provides a kind of stable performance, guarantees the stifle nut that stifle is pushed away in the torque range of regulation.
The realization the technical solution of the utility model is, a kind of stifle nut comprises nut, stifle and baffle plate, it is characterized in that, in the described nut, stifle above, be provided with plastic base plate.
Advantage of the present utility model and effect be, for the plagiocephaly anchor pole, the backing plate that plastics are made will be not enlarge at the point of action of the active force at stifle center, and the force-bearing situation of stifle obtains changing, and stifle can not be backed down in the process that stirs; For the tack anchor pole, backing plate is extruded fragmentation in the whipping process, and converges toward the center in the stifle deformation process, and the point of action that affacts the active force on the stifle is diminished, and like this, when reaching the moment of torsion of regulation, stifle is pushed away smoothly.Use the utility model can save a large amount of anchor poles aborning and working efficiency is increased substantially.
Description of drawings:
Fig. 1 is that figure is partly cutd open in structural representation of the present utility model.
Fig. 2 is the worm's eye view of Fig. 1.
Number in the figure: 1 nut, 2 baffle plates, 3 plastic base plates, 4 stifles.
Embodiment:
Referring to Fig. 1, the material of described plastic base plate 3 is an alloy plastic.Referring to Fig. 1, Fig. 2, nut 1 is a hexagon nut, adopts the fine casting method manufacturing, baffle plate 2 is upright cylindrical shape when casting, after inserting plastic base plate 3 and stifle 4, the tail end with upright cylinder pushes formation baffle plate 2 to the center again, and backing plate 3 and stifle 4 are blocked.
Claims (2)
1, a kind of stifle nut comprises nut (1), stifle (4) and baffle plate (2), it is characterized in that, in the described nut (1), stifle (4) above, be provided with plastic base plate (3).
2, by the described stifle nut of claim 1, it is characterized in that the material of described plastic base plate (3) is an alloy plastic.
