Description
Technical field
The present invention relates to electric power fixture more particularly to a kind of firm formula locking devices.
Background technique
For electrical domain, power supply unit such as transformer pile head, ground line pile crown, switch pile crown and lighting arrestor pile etc. are needed
When it being clamped or be detected, this just needs to fasten pile crown, however, at present can only be to the stake of single specification type
Head is clamped, and inconvenience is adjusted, and reduces practicability.
Distribution transformer measurement is such as carried out, mainly includes insulation resistance, DC measurement, changed test line mode of connection frequency
Numerous, running transformer will also carry out safety measure in addition, tear open, take high-low voltage leads, and average every transformer measures work
At least 20 minutes when effect.As rate of qualified voltage management in recent years requires higher and higher, transformer is transferred the files work in annual operation
To make at 1000 or more, accuracy in order to ensure the test results needs to remove transformer pillar head surface dirt and oxide, and
Test clamp is compressed, to reduce the conductive contact resistance in test loop, the clamping of p-wire wire clamp is elastic all by spring,
When wire clamp opening is in maximum rating, the compression travel that spring is subject to is maximum, and spring fatigue, causes and be tested over time
Object connects not close problem, and p-wire wire clamp is thus be easy to cause to damage.
It cuts off wire clamp again multiply annealed copper wire is directly connected on transformer pile head, p-wire multiply core is easy to wear until nothing
Method uses, thus is replaced using common modeling copper wire, influences the correctness of test result.
Summary of the invention
The present invention is easy to connect in view of the above problems, to provide a kind of structure simple, locks reliable and stable firm formula lock
Tight device.
The technical scheme is that including vertical plate, bracket, copper strips and locker, the vertical plate is from left to right successively set
There are lockhole one, location hole and lockhole two, the lockhole one is connected with location hole, and the bracket fixation is located at positioning hole,
One end of the copper strips is fixedly connected on bracket, and the other end is connected on bracket by locker；The copper strips is successively
It across lockhole one and lockhole two and is wound around on bracket in a ring, accommodating space is equipped between the bracket and copper strips；
The locker includes bottom plate and is located at bottom plate both ends baffle disposed in parallel, and the bottom plate is fixedly connected on bracket,
It being equipped between a pair of of baffle around axis and shaft, the shaft is located at around the top of axis, and it is described that spacing is equipped between axis and bottom plate,
The shaft is equipped with pressure ball, and the pressure ball is equipped with driving lever.
The top of the lockhole one is equipped with opening.
The pressure ball surface is equipped with fluting.
The surface of the pressure ball is smooth.
The copper strips is copper braid over braid, and the both ends of the copper braid over braid are respectively equipped with scolding tin body.
One end of the copper strips is welded to connect on bracket.
At work, copper strips sequentially passes through lockhole one and lockhole two and is wound around on bracket in a ring the present invention, plays pair
The position-limiting action of copper strips；Accommodating space between copper strips and bracket carries out locking action by locker for placing pile crown；Lock
When tight device movement, copper strips is first passed through from pressure ball bottom, then is passed through from the spacing between axis and bottom plate, is surround around axis rear steering again
It is secondary to pass through pressure ball bottom, pressure ball and bottom plate are shortened after rotation since pressure ball is in flat at this point, stirring driving lever rotation pressure ball
The distance between, in this way, two layers of copper strips of pressure ball bottom is compacted, thus by being reliably fixed.

Specific embodiment
The present invention is as shown in Figs 1-4, including vertical plate 5, bracket 1, copper strips 2 and locker, and the vertical plate is from left to right successively
Equipped with lockhole 1, location hole 52 and lockhole 2 53, the lockhole one is connected with location hole, and the bracket fixation is located at positioning
In hole, copper strips is through in lockhole one and lockhole two, plays the position-limiting action to copper strips, improves stability.
One end of the copper strips is fixedly connected on bracket, and the other end is connected on bracket by locker；The copper strips
It sequentially passes through lockhole one and lockhole two and is wound around on bracket in a ring, accommodating space 3 is equipped between the bracket and copper strips；Hold
For placing pile crown etc. between emptying；
The locker includes bottom plate 41 and is located at bottom plate both ends baffle 42 disposed in parallel, and the bottom plate is fixedly connected on bracket
On, it is equipped between a pair of of baffle around axis 43 and shaft 44, the shaft is located at around the top of axis, described to set between axis and bottom plate
There is spacing, passed through convenient for copper strips, the shaft is equipped with pressure ball 45, and the pressure ball is equipped with driving lever 451.
In work, the distance of pressure ball and bottom plate weaves twice of tape thickness slightly larger than copper, in this way, copper braid over braid is first from pressure ball
Bottom passes through, then passes through from the spacing between axis and bottom plate, around pressure ball bottom is again passed through around axis rear steering, at this point, dialling
Dynamic driving lever rotates pressure ball, since pressure ball is in flat, the distance between pressure ball and bottom plate is shortened after rotation, in this way, pressure ball bottom
Two layers of bronze medal braid over braid in portion is compacted, thus by being reliably fixed.
The top of the lockhole one is equipped with opening 54.Lockhole one is opening, is overlapped convenient for copper braid over braid, plays limit and makees
With.Lockhole two be it is silent, copper braid over braid plays position-limiting action after penetrating.
The pressure ball surface is equipped with fluting 452.The frictional force between pressure ball and copper strips is increased, fixed effect is further increased
Fruit.
The surface of the pressure ball is smooth.While ensuring that fixed function is reliable, copper braid over braid is not damaged, extends copper braiding
The service life of band.
The copper strips 2 is copper braid over braid, and the both ends of the copper braid over braid are respectively equipped with scolding tin body.Using copper braid over braid, mention
High contact reliability；The both ends of copper braid over braid are sealed by scolding tin, and after preventing copper braid over braid broken lot from damaging, easy to damage, raising makes
Use the service life.
One end of the copper strips is welded to connect on bracket.By being welded to connect, facilitate processing.
