Description
Technical field
This utility model relates to technical field of electric power construction, particularly relates to a kind of link rod.The present invention relates to a kind of new-type
Power system customary insulation action bars, also known as link rod, insulating tool charging equipment operated for the short time, this
Design changes the interface structure of conventional helical formula link rod, has assembling, convenient disassembly, time saving and energy saving feature during use.
Background technology
Link rod also known as brake pull-rod, insulating bar, insulated tension pole, mainly be switched on or switched off high voltage isolator, fall molten
Silk tool, mounting or dismounting Portable ground wire and use when measuring and test.Link rod is by the band work upper joint of head and band lever
Lower joint composition, the interface of upper joint and lower internode uses threaded, by two insulating bar screw threads alignments during connection, screws
Operate with.But owing to the junction of irony gets rusty easily, especially screw thread gets rusty, and causes screw thread to screw the most not in place, install,
Dismounting is wasted time and energy；In addition union joint deformation also results in screw thread and is difficult to precession, it is impossible to normally use.Additionally, due to upper joint and
Lower joint length is fixed, and after assembling, link rod length is fixed, and cannot meet requirement when needing the link rod of different length.
Utility model content
The purpose of this utility model is to provide a kind of link rod, its assembling, convenient disassembly, is connected firmly, and can be according to need
Different length to be assembled into.
The technical solution adopted in the utility model is:
A kind of link rod, saves including upper joint and multiple prolongation, and the upper end of described upper joint is provided with work head, and lower end is provided with
Connecting male, one end of described prolongation joint is provided with connection male, and the other end is provided with connection female, and described connection male includes public set
Cylinder and ball, public sleeve wall lateral symmetry is provided with 2 pairs of ball installing holes, and ball embeds in ball installing hole, public barrel bore
In be additionally provided with ball fixed mechanism；Described connection female includes mother sleeve, and on mother set barrel, both sides are provided with at least 2 to solid
Determine hole, during the 2 pairs of balls snap in the fixing hole of mother sleeve on public affairs sleeve when public sleeve inserts mother sleeve.
Further, described ball fixed mechanism is made up of hollow transverse axis and the spring being placed in transverse axis cavity.As
A kind of optimal way, 4 ball mounting hole site in public sleeve wall are on same shaft section, and the two ends of a hollow transverse axis connect
Being positioned at two balls of same level, two hollow transverse axis are arranged in parallel.As another kind of optimal way, in public sleeve wall
4 ball mounting hole site are in same level, and the two ends of a hollow transverse axis connect two rollings being positioned on same shaft section
Pearl, two hollow transverse axis decussation arrangements.
Further, described connection male, connection female, ball all use steel to make.
The utility model has the advantages that (1) simple in construction, easy to operate.(2) during using, ball is with fixing hole hole even
Connect firmly, it is ensured that do not have the situation about rotating that gets loose.(3) interface, ball all use high strength steel to make, service life
Long, it is unlikely to deform.

Detailed description of the invention
Link rod of the present utility model, saves including upper joint and multiple prolongation.The structure of upper joint as described in Figure 1, upper joint upper
End is provided with work 1, and lower end is provided with connection male 2.Extend the structure of joint as in figure 2 it is shown, the one end extending joint is provided with even
Connecing male 4, the other end is provided with connection female 3, and the connection male 2 of the connection female 3 and upper joint that extend joint connects, and later extends
The connection female 3 of joint connects with the previous connection male 4 extending joint, thus realizes link rod and extend.
The connection male 2 of upper joint is as connection male 4 structure extending joint, including public sleeve 6 and ball 5, public sleeve
Wall lateral symmetry is provided with 2 pairs of ball installing holes, and ball 5 embeds in ball installing hole, is additionally provided with ball in public sleeve 6 inner chamber
Fixed mechanism.Connecting female 3 and include mother sleeve 8, on mother set barrel, both sides are provided with at least 2 pairs of fixing holes 9, and public sleeve 6 inserts
During 2 pairs of balls 5 on public affairs sleeve snap in the fixing hole 9 of mother sleeve during mother sleeve 8, thus male will be connected and connect female admittedly
Fixed.
Embodiment 1
In the present embodiment, ball fixed mechanism is provided in the hollow transverse axis 7 in public sleeve 6 and is placed on hollow transverse axis
Spring (omitting spring in figure) in 7 cavitys, ball 5 one end falls into transverse axis chamber and contact spring, and the other end is placed in ball and installs
Kong Zhong, can realize ball and fix and can the most slightly stretch.4 ball mounting hole site on public sleeve 6 wall are cut in same axle
On face, the two ends of a hollow transverse axis 7 connect two balls being positioned at same level, and two hollow transverse axis 7 are arranged in parallel.Even
Connecing and be correspondingly provided with 4 fixing holes 9 in female, in order to fix 4 balls, two fixing holes 9 of female sleeve 8 homonymy arrange
String, i.e. the fixing hole center of circle is become to be positioned on same vertical axis.
On the basis of the present embodiment, connect and in female, longitudinally can be provided with 2n fixing hole (integers of n >=2), preferably 6
Or 8, connect the ball in male and be fixed in different fixing holes according to entering the position connecting female, it is possible to achieve crane
