Abstract
The invention discloses an anti-rotating bolt. The anti-rotating bolt comprises a screw rod with the top end as a screw cap and the tail end as a thread section; polygonal through holes are formed in the whole middle part of the screw rod in the axial direction; limiting rods with matched shapes and sizes are inserted in the through holes; and handles and baffle plates are fixedly connected at the top ends of the limiting rods. The anti-rotating bolt can prevent the screw rod from rotating through the handles and the limiting rods when the nut is screwed on the thread section, effectively improves the mounting efficiency of the nut, and improves the connecting efficiency of the bolt.
Description
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of anti-rotation bolt.
Background technology
Bolt is a kind of bindiny mechanism being easily installed and dismantling, and the connection being usually used between plate is fixed, spiral shell
When bolt is installed, typically also need on thread segment, be socketed the connection peace that a nut matched with it realizes
Dress.For the installation of part sheet material, before installation, have counterbore at plate surface, its objective is bolt
Nut be placed in the counterbore that sheet material is offered, it is ensured that the finishing of plate surface after connection；But typically these counterbores
Internal diameter all big than nut, first bolt is placed in counterbore during installation, then from the bolt other end by nut revolve
Connect, but easily drive bolt to rotate in the nut process that spins, have impact on the joint efficiency of bolt.
Summary of the invention
It is an object of the invention to: a kind of anti-rotation bolt is provided, counterbore need to be arranged on solving conventional bolt
Existing time middle easily rotate the problem affecting installation effectiveness.
The present invention is achieved by the following technical solution:
A kind of anti-rotation bolt, including top be cap end be the screw rod of thread segment, edge in the middle part of described screw rod
Axially entire body has polygonal through hole, is fitted with the gag lever post matched with its geomery in through hole, limit
Position masthead end is connected with handle and baffle plate.
Described gag lever post and through hole are triangle, rectangle or hexagon.
The length of described gag lever post is more than the length of screw rod.
The invention has the beneficial effects as follows:
Compared with prior art, the anti-rotation bolt that the present invention provides, in the middle part of screw rod, have a through hole, and
Piece polygonal gag lever post of plug-in mounting in through hole, gag lever post top is provided with handle, by handle and gag lever post energy
Prevent from spinning on thread segment nut time screw rod rotate, be effectively increased the installation effectiveness of nut, and then
Improve the joint efficiency of bolt.
Accompanying drawing explanation
Fig. 1 is the structure chart of the present invention；
In figure: 1-thread segment, 2-screw rod, 3-nut, 4-baffle plate, 5-handle, 6-gag lever post.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described further, but required protection domain is also
It is not limited to described；
As it is shown in figure 1, the present invention provide anti-rotation bolt, including top be nut 3 end be thread segment 1
Screw rod 2, in the middle part of described screw rod 2, entire body has polygonal through hole vertically, is fitted with and its shape in through hole
The gag lever post 6 that size matches, gag lever post 6 top is connected with handle 5 and baffle plate 4.
In order to improve the scope of application of the present invention and ensure the intensity of screw rod 2, described gag lever post 6 is three with through hole
Dihedral, rectangle or hexagon.
In order to avoid gag lever post 6 comes off, the length of described gag lever post 6 is more than the length of screw rod 2.
During use, first screw rod 2 is inserted in the counterbore offered on sheet material, then gag lever post 6 is inserted screw rod 2
In the through hole that middle part is offered, and ensure that the baffle plate 4 at gag lever post 6 top is fitted with nut 3, now gag lever post 6 end
End stretches out bottom screw rod 2, and installation personnel i.e. can use one to hold handle 5 another hands can carry out nut
Installing, gag lever post 6 can effectively prevent screw rod 2 with nut rotation, be effectively improved installation effectiveness.
Claims (3)
1. an anti-rotation bolt, including top be nut (3) end be the screw rod (2) of thread segment (1),
It is characterized in that: described screw rod (2) middle part entire body vertically has polygonal through hole, is fitted with in through hole
The gag lever post (6) matched with its geomery, gag lever post (6) top is connected with handle (5) and baffle plate
(4)。
Anti-rotation bolt the most according to claim 1, it is characterised in that: described gag lever post (6) is with logical
Hole is triangle, rectangle or hexagon.
