Description
Technical field
The utility model relates to electric power fixture more particularly to a kind of adjustable locking apparatus.
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.
Utility model content
The utility model is in view of the above problems, simple, easy to connect, the adjustable lock of reliable lock that provides a kind of structure
Tight device.
The technical solution of the utility model is: including bracket, copper strips and locker, the copper strips is arranged in a ring, described
One end of copper strips is fixedly connected on bracket, and the other end is connected on bracket by locker；It is set between the bracket and copper strips
There is accommodating space；
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
On, be equipped between a pair of of baffle around axis and shaft, the shaft is located at around the top of axis, it is described be equipped between axis and bottom plate between
Away from the shaft is equipped with pressure ball, and the pressure ball is equipped with driving lever.
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.
The bracket is located at one end in accommodating space equipped with arc groove.
At work, copper strips is wound around on bracket the utility model in a ring, and the accommodating space between copper strips and bracket is used
In placing pile crown, locking action is carried out by locker；When locker acts, copper strips is first passed through from pressure ball bottom, then from around axis
Spacing between bottom plate passes through, and surround and again passes through pressure ball bottom around axis rear steering, at this point, driving lever rotation pressure ball is stirred, by
In pressure ball in flat, the distance between pressure ball and bottom plate are shortened after rotation, in this way, two layers of copper strips of pressure ball bottom is pressed
It is real, thus by being reliably fixed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model,
Fig. 2 is the structural schematic diagram of locker,
Fig. 3 is the structural schematic diagram of copper strips；
1 is bracket in figure, and 10 be arc groove, and 2 be copper strips, and 3 be accommodating space,
41 be bottom plate, and 42 be baffle, and 43 be around axis, and 44 be shaft, and 45 be pressure ball, and 451 be driving lever, and 452 be fluting.
Specific embodiment
As shown in Figure 1-3, including bracket 1, copper strips 2 and locker, the copper strips is arranged the utility model in a ring, described
One end of copper strips is fixedly connected on bracket, and the other end is connected on bracket by locker；It is set between the bracket and copper strips
There is accommodating space 3；Accommodating space is for placing pile crown etc.；
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
Be equipped on bracket, between a pair of of baffle around axis 43 and shaft 44, the shaft is located at around the top of axis, it is described around axis and bottom plate it
Between be equipped with spacing, passed through convenient for copper strips, the shaft be equipped with pressure ball 45, the pressure ball be 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 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.
The bracket is located at one end in accommodating space equipped with arc groove 10.Arc groove is set, convenient for carrying out to pile crown etc.
Positioning improves connection reliability.
