Description

Anti-skid and anti-loosening double-headed hexagon bolt

Technical Field

The utility model belongs to the technical field of the bolt, concretely relates to anti-skidding locking double-end hexagon bolt.

Background

The stud is one of the bolts, and the stud is used for a fixed link function of a connecting machine. The method is generally used for mining machinery, bridges, automobiles, motorcycles, boiler steel structures, tower cranes, large-span steel structures, large-scale buildings and the like.

When being used for connecting two connecting pieces, the existing hexagon stud sometimes screws a connecting piece through the screw thread with a logical of stud earlier, and another connecting piece itself is inconvenient to rotate, can set up the through-hole this moment on another connecting piece, directly passes the through-hole with stud's the other end after, and reuse nut screws on stud's the other end, thereby the nut screws and has played the fixed action and connected two connecting pieces after laminating with the inner wall of second connecting piece.

The problem that above-mentioned using-way exists is that stud hexagon's the other end directly passes the through-hole and uses the nut fixed, and stud hexagon's screw rod and through-hole can not laminate by precision, thereby has the connecting piece to slide, rotate and lead to the dislocation to make the connecting piece connect unstable possibility.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a locking double-end hex bolts of antiskid for when connecting the connecting piece that one side is the through-hole, reduce to slide, rotate and lead to the not hard up possibility of connecting piece to improve connection stability.

In order to achieve the above object, the utility model provides a locking hex head bolt of antiskid, this locking hex head bolt of antiskid includes first screw rod, second screw rod and hexagon bolt head, wherein, first screw rod sets up on the first face of hexagon bolt head, the second screw rod sets up on the second face of hexagon bolt head, be provided with the screw thread pore on the second face of hexagon bolt head, detachably installs the anti-skidding pole in the screw thread pore.

The utility model provides a locking double-end hexagon head stud of antiskid inserts the second screw rod in the through-hole on the connecting piece after, can set up a aperture that matches with the anti-skidding pole in near this through-hole, then will anti-skidding the pole and insert in the aperture, use the nut to screw up simultaneously on anti-skidding pole and second screw rod to it is fixed to have realized the multi-end, slides, rotates to lead to connecting not hard up possibility with reducing the connecting piece.

In a possible implementation manner, six threaded fine holes are uniformly arranged on the hexagonal bolt head along the outer side edge, and at least two anti-sliding rods are arranged. The more the number of the arranged anti-slip rods is, the more difficult the connecting piece is to loosen.

In one possible implementation, the anti-slip rod is provided with a thread. The threads are used to attach the anti-slip rod into the threaded bore and to mount a nut on the anti-slip rod.

In a possible implementation manner, the front end of the anti-sliding rod is provided with a first anti-sliding texture. The first anti-slip texture is used for reducing the possibility of sliding when the anti-slip rod is screwed into the threaded pore.

In a possible implementation manner, the side wall of the hexagonal bolt head is provided with a second anti-slip line. The second anti-slip lines are used for reducing the possibility of slip when the hexagonal bolt head is screwed.

In a possible implementation, the top end of the second screw is provided with an inner hole. The bore at the top of the second screw may be used to rotate the entire hex stud.

Detailed Description

The following description is provided to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments described below are by way of example only, and other obvious variations will occur to those skilled in the art. The underlying principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a particular orientation, be constructed in a particular orientation, and operate, and thus, should not be construed as limiting the present application.

In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to imply that the number of indicated technical features is significant.

Referring to fig. 1 of the drawings, fig. 1 is a structural schematic view of an anti-slip and anti-loose stud bolt provided by the utility model, as shown in fig. 1, the utility model provides an anti-slip and anti-loose stud bolt includes first screw 1, second screw 2 and hexagon bolt head 3, wherein, first screw 1 sets up on the first face of hexagon bolt head 3, second screw 2 sets up on the second face of hexagon bolt head 3, be provided with screw thread pore 4 on the second face of hexagon bolt head 3, anti-slip rod 5 is installed to detachably in screw thread pore 4.

The utility model provides a locking hex head bolt of antiskid inserts the second screw rod 2 back in the through-hole on the connecting piece, can set up a aperture that matches with antiskid pole 5 in near of this through-hole, then will prevent that slide bar 5 inserts in the aperture, uses the nut to screw up on antiskid pole 5 and second screw rod 2 simultaneously to it is fixed to have realized the multi-end, slides in order to reduce the connecting piece, rotates and lead to connecting not hard up possibility.

In a possible embodiment, six threaded holes 4 are provided uniformly along the outer side on the hexagonal bolt head 3, and at least two anti-slip rods 5 are provided. The more the number of the provided anti-slip bars 5 is, the less the connecting member is loosened.

As shown in fig. 2, for the utility model provides a pair of locking hex head bolts of antiskid uses the schematic diagram, as shown in fig. 2, using this locking hex head bolt of antiskid, the downside still is provided with two pores on the through-hole of connecting piece, two anti-skidding poles 5 are installed at corresponding position on the hexagon bolt head 3, two anti-skidding poles 5 pass two pores respectively, all use the nut to screw up on two anti-skidding poles 5 and the second screw rod 2 to the lateral wall of this connecting piece to it is fixed to have realized connecting.
