Description
Technical field
The present invention relates to the technical field that electric power meter is installed, and in particular to a kind of ammeter box installation aid
And its application method.
Background technology
In recent years, power system increases the upgrading dynamics of ammeter box, when installing ammeter box, because ammeter box has
Certain depth, narrow space, when tamping fixture (iron nail or expansion bolt), operation is extremely inconvenient, and iron hammer easily injures hand by a crashing object
Refer to, cause injury to personnel.
About 10 centimetres of ammeter box depth, is already installed with two switches, an electric energy meter, substantially inside ammeter box during installation
Without redundant space, and needed when tapping it is careful beat iron nail or expansion bolt with iron hammer, it is careless slightly easily to damage ammeter box,
Cause to waste.
Because of the ammeter box of landing of long duration after to fixing, when retightening, circuit is powered in ammeter box, taps operation slightly
There is deviation to touch powered position, cause personnel to get an electric shock injured.
The U of Chinese patent Authorization Notice No. CN 202062356, disclose a kind of iron nail holder, it provide it is a kind of by
The iron nail holder of groove and supporting rod composition, a retractable groove is set in the termination of supporting rod.When beaing iron nail, iron nail
Along the groove slide downward of supporting rod, into working face, nail iron nail work is completed.The present invention is solved when hand steered positive iron nail
When, the problem of being easier to injure finger by a crashing object, but the problem of working space as fixing during ammeter box is narrow and small can not be solved.
Chinese patent Authorization Notice No. CN200970756 Y, disclose a kind of nail holder, including taper spring folder, pipe
And cylindrical handle, spring clip is fixedly connected with pipe, and cylindrical handle is caught in pipe, and taper spring is pressed from both sides at least provided with two grooves, pipe wall
It is provided with match shape groove；Iron nail is imported from pipe wall provided with match shape groove, is retracted into through cylindrical handle to taper spring folder, with one
Hand holds pipe, then strikes with iron hammer cylinder negative winding stem, you can iron nail is hammered on the object of specified location.The present invention is solved
The problem of work in narrow space, but may be only available for fixing first uses, when ammeter box iron nail of long duration or expansion bolt pine
After dynamic, because taper spring presss from both sides insufficient strength, this instrument is caused not use.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of ammeter box installation aid and its application method, energy
Enough fixtures when solving fixed ammeter box because narrow space can not tap fixture the problem of, while can be with when fixture loosens
It is convenient to knock in working face again.
The present invention solves the technical scheme that is used of its above mentioned problem：A kind of ammeter box installation aid is provided,
Including sleeve body, spanner groove, claw chamber, interior pawl chamber, claw and interior pawl；The sleeve body rear end is provided with what is caved inward,

In order to preferably reach using effect, the face on the basis of the back plan of sleeve body 2, fore-set 24, the and of interior annular 25
The vertical height of the not-go-end plane separation reference plane of outer toroid 26 is successively decreased successively, can so prevent the interior annular caused by metope out-of-flatness
25 and outer toroid 26 withstand metope, the situation that the nail tail 11 of iron nail 1 can not be tapped on earth completely occurs.Claw in simultaneously of the invention
First 33 use uniform four groups with integral connection sheet 32, so can preferably clamp iron nail 1, the diameter of fore-set 24 is more than
Iron nail 1 follows closely the diameter of tail 11, and nail tail 11 can be stuck in calvus 42, prevent iron nail 1 from dropping.In the present invention, in spanner groove 21
Also one does not outwards extend out the boss 211 of the plane of the opening of spanner groove 21, and sleeve is lengthened when boss 211 can effectively prevent from tapping
Bar plug crosses tight fit with spanner groove 21, and the situation that sleeve extension bar can not be taken out after the completion of use occurs.
Meanwhile, based on the structure of above ammeter box installation aid, the invention also discloses a kind of installation of ammeter box
With the application method of aid, comprise the following steps：
Step 1：Interior latch spring 45 is put into interior pawl chamber 23, and interior pawl 4 is put into interior pawl chamber by interior pawl locating piece 44
In 23, interior pawl 4 due to the effect of interior pawl locating slot 241, can the axial sliding movement that does without rotation, and pass through interior pawl block
242 are limited；
Step 2：Claw spring 35 is put into claw chamber 22, and claw 3 is put into claw chamber by claw locating piece 34
In 22, claw 3 due to the effect of claw locating slot 251, can the axial sliding movement that does without rotation, and pass through claw block
252 are limited；
Step 3：The nail tail 11 of iron nail 1 is put into the claw of claw 3 first 33 backwards, due to the work of flexible connection piece 32
With iron nail 1 is clamped in claw first 33；
Step 4：Iron nail 1 is urged rearwardly into, made on the fore-set 24 that nail tail 11 is connected in the interior calvus 42 of pawl 4；
Step 5：By in the spanner groove 21 of the plug insertion sleeve main body 2 of sleeve extension bar, tap sleeve with iron hammer and lengthen
Bar afterbody；
Step 6：Progressed into iron nail 1 is tapped in wall, metope pushes first 33 front end of claw of claw 3, along card
Pawl chamber 22 is taken in slot 253, tap to nail body 12 enter wall it is interior and follow closely tail 11 also outside when, metope pushes interior pawl 4
The front end of calvus 42, by interior pawl income into interior pawl chamber 23；
Step 7：Front end face due to the front end face of fore-set 24 higher than interior annular 25 and outer toroid 26, iron nail 1 will be unobstructed
Tap in place.
To sum up, only presently preferred embodiments of the present invention, not for limiting the scope of the present invention, is said by above-mentioned
Bright content, relevant staff completely can without departing from the scope of the technological thought of the present invention', carry out various change with
And modification.The technical scope of this invention is not limited to the content on specification, the shape of all claimed ranges under this invention
