Abstract
The utility model relates to a machinery construction installation equipment field discloses a box spanner for round nut, does not receive space limitation just can be applicable to the round nut of different specifications when the assembly round nut. Including the cover barrel of cylinder, but cover barrel radial shrinkage, the one end of cover barrel has four bosss along circumference evenly distributed. Through the cover cylinder bottom in the cylinder set up with the round nut boss that cooperatees, can follow the top and assemble the round nut, do not receive space limitation, convenient assembling, but cover barrel radial shrinkage comes the diameter of adjusting sleeve barrel, can satisfy the assembly requirements of different specification round nuts, and the suitability is wider, when using the cover barrel assembly round nut of cylinder, the round nut atress is even, and the local stress is little, is difficult for leading to the fact the damage.
Description
Technical field
This utility model relates to mechanical frock apparatus field, especially a kind of round nut box spanner.
Background technology
Pass round nut to be widely used in engineering goods as securing member, typically use crescent moon when assembling maintenance or maintenance round nut
Spanner fastens or loosens round nut, but knuckle buster exists a lot of problem in actual use, such as: is tightening or is loosening circle
Only having some stress during nut, local stress is relatively big, is easily damaged round nut；For being arranged on the round nut of interiors of products, the moon
Tooth spanner cannot use because space limits；For the round nut of different size, need to change the knuckle buster of equivalent specifications, use
Inconvenience.
Utility model content
Technical problem to be solved in the utility model is: provides a kind of round nut box spanner, is not subject to when component location guide nut
Space limits and can be suitably used for the round nut of different size.
Round nut box spanner is the technical scheme is that, including cylindrical shape by solving above-mentioned technical problem this utility model
Sleeve body, sleeve body can radial contraction；One end of sleeve body is circumferentially evenly distributed with four boss.
Further: described sleeve body is made up of four pieces of arc plates matched, and arc plate is hollow structure, between arc plate
Connect by shrinking sheet, shrink and connected by the spring being arranged in arc plate between sheet.
Further: the other end of described sleeve body is provided with the most equally distributed four through holes, also includes through through hole
Screw rod, the two ends of screw rod are designed with external screw thread, and the two ends of screw rod are threaded adjusting nut.
Further: one end of described arc plate is provided with chimb, chimb inserts in adjacent arc plate.
The beneficial effects of the utility model are: by arranging the boss that matches with round nut in columnar sleeve body lower end, can be from
Round nut is assembled by top, is not limited by a space, easy to assembly；Sleeve body radial contraction can carry out the diameter of adjusting sleeve cylinder,
Can meet the matching requirements of different size round nut, the suitability is wider；When using columnar sleeve body component location guide nut, circle spiral shell
Female uniform force, local stress is little, does not easily cause damage.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is top view of the present utility model；
Figure is labeled as: 1-sleeve body, 11-boss, 12-arc plate, 121-chimb, 13-shrink sheet, 2-screw rod, 21-tune
Joint nut.
Detailed description of the invention
For the ease of understanding this utility model, below in conjunction with the accompanying drawings this utility model is further detailed.
As shown in Figure 1 and Figure 2, this utility model round nut box spanner, including columnar sleeve body 1, sleeve body 1 can
Radial contraction；One end of sleeve body 1 is circumferentially evenly distributed with four boss 11, boss 11 and four slotted eyes on round nut
Corresponding.Sleeve body 1 by four pieces match, arc plate 12 that specification is identical forms, arc plate 12 is hollow structure, adjacent
Being connected by contraction sheet 13 between arc plate 12, the arc plate 12 of hollow is internal is provided with spring, shrinks sheet 12 and is connected to spring
On, the contraction of spring pulls contraction sheet 13 to move and drives adjacent arc plate 12 close or separate, thus realizes sleeve body 1
Radial contraction.The other end at sleeve body 1 is provided with through hole, and through hole is on relative arc plate 12 each one, passes in through hole
Screw rod 2, screw rod 2 staggered cross；The one or both ends of screw rod 2 are provided with external screw thread, and the threaded adjusting nut having coupling
21；If there is external screw thread at the two ends of screw rod 2, the two ends of the most every screw rod 2 connect an adjusting nut 21；If screw rod 2
There is one end to be provided with external screw thread, the most only connect an adjusting nut 21, be not provided with fixing spacing such as block etc in externally threaded one end
Part.
When assembly or disassembly round nut, boss 11 is snapped in slotted eye corresponding on round nut, then by rotating on screw rod 2
Adjusting nut 21 carrys out the diameter of regulating sleeve body 1 until clamping round nut, is then rotated further by sleeve body 1 and can realize round nut
Unscrew or tighten.
In order to increase the intensity of sleeve body 1, i.e. increase the bonding strength between arc plate 12, arrange in one end of arc plate 12
Chimb 121, chimb 123 inserts in adjacent arc plate 12, being staggeredly located of chimb 121 on adjacent circular arc plate 12, makes circle
The bonding strength at arc plate 12 two ends is the most secure.
