In the figure: the nut comprises a nut body 1, a nut body 100 accommodating cavity 101, a nut opening 101, a nut blocking piece 102, a nut blocking piece 1020 groove, a screw rod 2, a screw rod 200 connecting piece, a screw rod 2000 connecting piece bulge, a screw rod 201 blocking piece, a nut 3, a first 300 annular tooth-shaped structure, a locking piece 4 and a second 400 annular tooth-shaped structure.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 5, a corrosion-resistant fastening bolt for a highway guardrail comprises a nut 1, a screw 2, a nut 3 and a locking piece 4. Different from the traditional bolt, the utility model provides a screw rod 2 and nut 1 be the components of a whole that can function independently structure. Screw rod 2 is T shape structure, the head of screw rod 2 sets up the screw rod connection piece 200 of a straight line, the inside of nut 1 has columniform nut and holds chamber 100, nut opening 101 identical with screw rod connection piece 200 shape is seted up to a side end face of nut 1, nut opening 101 holds chamber 100 intercommunication with the nut, and set up nut separation blade 102 between the two, screw rod connection piece 200 holds and holds chamber 100 and keep off with nut separation blade 102 in the nut and connect, the afterbody at screw rod 2 is established in proper order to stay 4 and nut 3 cover. The end surface of the nut block piece 102 facing the nut accommodating cavity 100 is provided with a nut block piece groove 1020, and the screw connecting piece 200 is provided with a screw connecting piece bulge 2000 clamped into the nut block piece groove 1020.
The middle part of screw rod 2 has the external screw thread, and the afterbody of screw rod 2 does not have the external screw thread, and the afterbody of screw rod 2 is the screw rod dog 201 that the restriction nut 3 pine takes off from screw rod 2 still fixedly connected with.
In another embodiment of the present invention, the nut 3 is provided with a first annular tooth-shaped structure 300 towards the end surface of the locking plate 4, the locking plate 4 is provided with a second annular tooth-shaped structure 400 towards the end surface of the nut 3, and the first annular tooth-shaped structure 300 is meshed with the second annular tooth-shaped structure 400. The nut 3 is connected with the locking sheet 4 through a tooth-shaped structure, so that the nut can be prevented from loosening.
During installation, the screw connecting piece 200 sequentially penetrates through the to-be-connected piece and the nut opening 101 to enter the nut accommodating cavity 100, then the screw 2 is rotated, the screw connecting piece 200 is staggered with the nut opening 101, meanwhile, the screw connecting piece 200 is in blocking connection with the nut blocking piece 102, then the screw 2 is pulled towards the tail end, the screw connecting piece protrusion 2000 is clamped into the nut blocking piece groove 1020, then the locking piece 4 is sleeved, and finally the nut 3 is screwed.
When the nut 3 is disassembled, the nut 3 is firstly rotated to prevent the screw from being locked by the nut 3, the screw 2 is pressed to enable the screw connecting piece bulge 2000 to be separated from the nut retaining piece groove 1020, then the nut 1 is rotated to enable the screw connecting piece 200 to be aligned with the nut opening 101, then the nut 1 is taken down, and finally the rest parts of the bolt are taken down.
Obviously, since the head end of the screw rod 2 of the present invention has the screw rod connecting piece 200, the shape of the screw rod connecting piece 200 is different from that of the circular hole, and therefore, the connecting hole on the connecting piece should be designed to be in a shape corresponding to the screw rod connecting piece 200.
