Abstract
The utility model discloses a wrench special for tightening nuts. The wrench special for the tightening nuts comprises a metal sleeve and a handle arranged at one end of the metal sleeve, wherein the metal sleeve is provided with an inner through hole, the inner through hole of the metal sleeve are of a hexagonal prism structure assembled with the tightening nuts in a matched mode, a non-metal check ring used for preventing the tightening nuts from extending into the upper portion of the metal sleeve is arranged at the position, 5mm away from the lower edge of the metal sleeve, of the bottom end of the metal sleeve, the check ring is in interference fit with the metal sleeve, and a neodymium iron boron powerful magnet is arranged on the inner wall, above the check ring, of the metal sleeve. The wrench special for the tightening nuts is convenient to use, inconvenience brought to working as the nuts disengage easily is eliminated, and working efficiency of operating personnel is greatly improved.
Description
Technical field
The utility model relates to the instrument that the wide model in a kind of power construction field is used, especially a kind of spanner.
Background technology
The binding nut of describing in GB805-88 standard, is with galvanizing moulding after stalloy punching press, is widely used in the outdoor large steel structure body with bolt-connection such as electric power, telecommunications steel tower.Yet because the manufacturing tolerance of binding nut own is larger; cannot use the sleeve of standard specification to install, as adopted common wrench to install, not only waste time and energy; and the phenomenon that also often there will be binding nut to drop in installation process, to construction operation, bring very big inconvenience.
Utility model content
The utility model technical issues that need to address are to provide a kind of easy to use, spanner of being exclusively used in binding nut, to improve construction operation efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Binding nut special spanner, comprise metal sleeve and the handle that is arranged on metal sleeve one end with inner via hole, the inner via hole of described metal sleeve is six prism structures that are equipped with mutually with binding nut, the bottom of metal sleeve is provided with for preventing that binding nut from stretching into the nonmetal back-up ring on metal sleeve top apart from 5mm depths, metal sleeve lower edge, back-up ring and metal sleeve interference fit, be provided with neodymium iron boron strong magnets on the metal sleeve inwall of back-up ring top.
The further improvement of the utility model concrete structure is: described back-up ring is wooden back-up ring or plastics back-up ring.
Owing to having adopted technique scheme, the obtained technological progress of the utility model is:
The utility model is, for GB805-88 binding nut, inconvenient problem is installed, and a kind of light instrument of design is easy to operate, safe and reliable.The back-up ring arranging on metal sleeve is used for preventing that binding nut from stretching into metal sleeve top, neodymium iron boron strong magnets is magnetic spanner band, solve nut in binding nut cargo handling process and held caducous problem, eliminate the inconvenience bringing to work because nut comes off, and greatly improved operating personnel's operating efficiency.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional view of metal sleeve described in the utility model.
In figure: 1, metal sleeve, 2, back-up ring, 3, neodymium iron boron strong magnets.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is explained in further detail:
Binding nut special spanner as shown in Figure 1, comprise metal sleeve 1 and the handle that is arranged on metal sleeve 1 one end with inner via hole, wherein the inner via hole of metal sleeve 1 is six prism structures, equipped mutually with binding nut, the bottom of metal sleeve 1 is provided with back-up ring 2 apart from 5mm depths, metal sleeve lower edge.
Between back-up ring 2 lateral surfaces and metal sleeve 1 inner face, adopt interference fit connected mode, back-up ring can apply one deck 502 glue in installation process on the lateral surface of back-up ring, with the reliability of further strengthening being connected between back-up ring and metal sleeve, being provided for of back-up ring prevents that binding nut from stretching into metal sleeve 1 top.
On the metal sleeve inwall of back-up ring 2 tops, be also provided with neodymium iron boron strong magnets 3, neodymium iron boron strong magnets 3 by magnetic-adsorption on metal sleeve 1, be used for making metal sleeve to there is magnetic force, be convenient to adsorb binding nut, prevent its loss that drops in installation and removal process.
The utility model guide ring 2 is light, soft by wooden or plastics etc., easily process and the nonmetallic materials that possess some strength and wearability are made.Neodymium iron boron strong magnets 3 also can adopt with strong permanent magnetic body and substitute.
When the utility model is used, first binding nut is put into the inner via hole of metal sleeve 1, then the rotation by handle is screwed into binding nut on the power equipment that will install.
Claims (2)
