Preferably, the tail end of the bolt is provided with a chamfer and corresponds to the opening of the nut.
Preferably, the connecting block is embedded with a magnetic block, and the magnetic block is magnetically attracted with an external road guardrail.
Preferably, the inner side surface of the connecting block is provided with a rubber layer.
(III) advantageous effects
Compared with the prior art, the utility model discloses possess following beneficial effect:
1. this kind of novel fastener is used in quick installation of highway guardrail, through being in the same place two bolted connection, and correspond with the mounting hole, connect the one end of two elastic hook of type of falling V above the connecting block, the nut that corresponds with the bolt is connected to the other end, during the installation, can directly connect the bolt and hang in the guardrail top, insert into to the mounting hole, then rotate the nut and can install, need not to aim at the mounting hole one by one at the workman, the fixing bolt that wastes energy again simultaneously, the grafting is convenient, and is convenient to fix, and the installation efficiency is improved.
2. This kind of novel fastener is used in quick installation of highway guardrail sets up to the chamfer structure through the one end with the bolt to bolted connection part has magnetism, can adsorb on the guardrail automatically during the installation, and fixed position, the convenience of installation is further improved to the nut of being convenient for and being connected between the bolt.

FIG. 2 is a schematic view of the overall structure of the elastic hook of the present invention;
fig. 3 is a schematic view of the cross-sectional structure of the connecting block of the present invention.
In the figure: 1. a bolt; 2. connecting blocks; 3. an elastic hook; 4. a guide block; 5. a nut; 6. a magnetic block; 7. a rubber layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1 and 2, the fastener for quickly installing the highway guardrail comprises two bolts 1 corresponding to guardrail installation holes, and is characterized in that one end of each bolt 1 is fixedly connected with a connecting block 2, the upper surface of the connecting block 2 is fixedly connected with an inverted-V-shaped elastic hook 3, the other end of each elastic hook 3 is fixedly connected with a guide block 4, a nut 5 corresponding to the bolt 1 is connected in the guide block 4 in a rotating manner, and the opening direction of the nut 5 corresponds to the tail end of the bolt 1. During the installation, hang elastic hook 3 in the guardrail top earlier, two bolts 1 correspond with the mounting hole, and link together through connecting block 2, can insert two bolts 1 simultaneously, guide block 4 corresponds with the tail end of bolt 1, make the position of nut 5 correspond with the tail end of bolt 1, the workman can directly rotate nut 5, couple together it with 1 threaded connection of bolt, and two 1 interconnect of bolt, and plug in the mounting hole, in order can not rotate along with nut 5, the workman need not fastening bolt on one side, the screw in spiral shell simultaneously, the convenience of pegging graft has been realized, and is fixed convenient, and the installation efficiency is improved.
As shown in fig. 1, furthermore, the tail end of the bolt 1 is chamfered and corresponds to the opening of the nut 4, so that the tail end of the bolt 1 is easier to be screwed by the nut 4 after the nut 4 is contacted with the bolt 1, and the threads of the nut and the nut can be more easily attached together.
As shown in fig. 3, further, the embedded magnetic path 6 that is equipped with of connecting block 2, magnetic path 6 and external highway guardrail magnetism inhale the setting, because every guardrail erection column often need respectively install a set of bolt 1 at last lower extreme, this design can be after bolt 1 inserts the mounting hole, adsorb on the guardrail automatically, when having avoided installation lower extreme bolt 1, the workman needs the work of manual fixed connection piece 2, and then the workman of being convenient for butt joint nut 4 and bolt 1.
As shown in fig. 3, further, the inner side surface of the connection block 2 is provided with a rubber layer 7, which is designed to prevent corrosion between the guard rail and the bimetal of the connection block, thereby reducing damage to the device.
The working principle is as follows: when installing the rail guard upside, hang elastic hook 3 in the guardrail top earlier, the shift position corresponds two bolts 1 with the mounting hole, can insert the mounting hole simultaneously with two bolts 1, when installing the rail guard downside, bolt 1 inserts behind the mounting hole, magnetic path 6 adsorbs on the guardrail, can fix the position, guide block 4 corresponds with the tail end of bolt 1 this moment, make the position of nut 5 correspond with the tail end of bolt 1, the workman can directly rotate nut 5, couple together it with bolt 1 threaded connection, and two bolt 1 interconnect, and plug in the mounting hole, with bolt 1 can not rotate along with nut 5, the workman need not fasten bolt 1 on one side, screw in nut 5 on one side, the convenience of pegging graft has been realized, and is convenient, and the installation efficiency is improved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
