Wire, accurate measurement is needed before construction and is calculated, obtains required conductor length, correct amount line taking length, poor practicability.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of strain clamp, this strain clamp is simple in construction,
It is easy to construct, efficiency of construction is high, calculates without accurate measurement before constructing, can wind longer wire, and is additionally provided with to offset to draw and answers
The spring of power, ensure that wire is not easy to break, improve the service life of wire.
In order to achieve the above object, the technical scheme that the utility model is taken：
Strain clamp, including the wrapping post in tubular, the both ends of the wrapping post are equipped with lead plate in disk form,
Two lead plates it is vertically arranged and symmetrically offer thereon it is some to threading hole, and the diameter of two lead plates be more than it is described around
The diameter of terminal, wherein being provided with a draw ring for being in semicircle shape at the center of a lead plate, one is connected with the center of the draw ring
The fix bar laterally set, the fix bar runs through two lead plates and wrapping post, and continues after the fix bar leadthrough plate
Extend outward, the end of the fix bar connects a spring, and it is in the form of annular discs and vertically arranged that the end of the spring is connected to one
Supporting plate on, one end of the supporting plate is connected with a cylindrical mounting post, and the mounting post is transversely mounted and thereon
Offer mounting hole.
As optimal technical scheme, in order to ensure that strain clamp stabilized structure, intensity are big, corrosion-resistant, while insulating properties
Good, the wrapping post and two lead plates are integrally formed and are made of ceramic materials.
As optimal technical scheme, in order to ensure the intensity of strain clamp, while corrosion resistance is improved, effectively extend strain insulator
The service life of wire clamp, the fix bar, spring, supporting plate, mounting post are made of stainless steel material.
Compared with prior art, the utility model has the advantage that：
1st, this strain clamp sets the lead plate for offering threading hole, can quickly and easily fix wire, changes existing
The defects of complex operation, a coiling is set, long wire can be wrapped on wrapping post, without accurate measurement before construction
Calculate, longer wire can be wound, and be additionally provided with the spring for offsetting tension, ensure that wire is not easy to break, improve making for wire
It is good with life-span, usability.
2nd, the structure of wrapping post and two lead plates, material are set scientific and reasonable, ensure strain clamp stabilized structure, intensity
Greatly, it is corrosion-resistant, while good insulation preformance.
3rd, fix bar, spring, supporting plate, the material of mounting post are set scientific and reasonable, ensure the intensity of strain clamp, simultaneously
Corrosion resistance is improved, effectively extends the service life of strain clamp.
