Abstract
The utility model discloses an anchor rod screw cap, relating to an anchor rod fitting. A cylindrical column body is arranged at the bottom end of an integral screw cap main body, a hexagonal rhombic/square/track-shaped column body is arranged at the top end of the integral screw cap main body, a thread through hole is arranged in the center of the main body, and the diameter of the screw cap main body is gradually increased from the bottom end to the top end in a steady manner. The anchor rod screw cap is manufactured by utilizing the mould-pressing technique and has the characteristics of convenient installation, reasonable force, high intensity, corrosion preventing, beautiful appearance, high production efficiency, simple manufacturing and long service life.
Description
Technical field
The utility model relates to a kind of anchor rod member, refers in particular to the anchor pole nut, and its material is the glass fibre reinforced plastics material.
Background technique
The generally cylindrical combined integrated structure with latter half part rhombus cylinder of the used anchor pole nut of coal mine support by front half part, there is tapped through hole the centre; In addition, also having entire body on the market is the nut of six rhombus cylindricalitys, in this nut using process, occurs force bearing point cracking between nut and the pallet easily.On material, be generally steel, steel anchor pole nut weight is big, complex manufacturing technology, the cost height, easy-to-rust can not use in water and corrosive material environment are arranged effectively for a long time, can produce spark when coal-cutting machinery cuts, may cause security incidents such as gas and dust explosion, safety coefficient is low.
Summary of the invention
The utility model purpose provides a kind of high strength and can firmly be connected the anchor pole nut of use with pallet.Main innovation is that the nut diameter is from bottom to top and increases progressively shape, and fluting is communicated with central through bore on the cap body, specifically implement like this: the anchor pole nut, it is the integrated nut body of bottom cylindrical column and top six rhombuses/square/runway shape cylinder, the body center is provided with tapped through hole, and the diameter that it is characterized in that the nut body is by the bottom and progressively increases progressively shape to the top.The anchor pole nut of this structure cooperates the anchor pole pallet of applying for a patent simultaneously, and is more reliable than the connection of plain nut.
Nut is threaded into the pallet through hole by the body of rod, after anchor pole integral body is stressed, force bearing point moves to the nut direction, this moment, pallet pressed the nut top, the nut and the body of rod are pressed tightlyer, nut through hole internal thread and the clamping of body of rod thread surface get over firmly, not only are difficult for skidding off, and can improve the whole strength of anchor pole.The utility model symmetry on the nut body offers the groove that communicates with the center tapped through hole.Described groove is driveed to the Lower Half of top cylinder by the body bottom, offers the groove of some.
In order to overcome the defective on the material and conveniently to process, the utility model adopts the glass fibre reinforced plastics material.
The anchor pole nut of model utility, easy for installation, stressed rationally the intensity height has anticorrosionly, appearance looks elegant uses mould pressing process to make, the manufacturing efficiency height, make simple, long product lifecycle.

Embodiment
The anchor pole nut, it is the integrated glass fiber reinforced plastic nut body of bottom cylindrical column 1 and top six rhombus cylinders 2, the body center is provided with tapped through hole 3, the diameter of nut body is by the bottom and progressively increases progressively shape to the top, symmetry offers the groove 4 that communicates with center tapped through hole 3 on the nut body, and described groove 4 is driveed to the Lower Half of top cylinder by the body bottom.
Annotate: according to actual needs, the top cylinder of nut body also can be designed to square or runway shape cylinder.
