Abstract
A special-shaped wrench for round nut relates to a machine mounting tool, and comprises the following components: a handle, a semi-circular-ring shaped bayonet, and a cuboid-shaped boss on the semi-circular-ring shaped bayonet. The circumferential width of the boss is slightly less than a groove equipped on the outer circle of the round nut. The utility model is characterized in that: the bosses on the semi-circular-ring shaped bayonet vertically project outwards on the end face of the semi-circular-ring shaped bayonet; three bosses with phase difference of 90 DEG are provided, and furthermore the three bosses are provided at two ends and the middle position of the semi-periphery of the semi-circular-ring shaped bayonet. The special-shaped wrench for round nut is advantageous in that: at the occasion when the peripheral space of the round nut is limited, through respectively inserting two pin paws at two sides of the special-shaped wrench in the groove at the end side of the nut for rotating by turns, the detachment or fixing operation is realized smoothly.
Description
Technical field:
The utility model relates to mechanical assembly tool, is specially adapted to dismounting of machinery equipment round nut structure or fastening used spanner.
Background technology:
In machinery equipment project installation or the maintenance process, the difference of the machine equipment performance of selecting for use directly affects operation quality and efficient.The nut that the running accessory of machinery equipment is used to be connected and fixed with helicitic texture, round nut particularly, the general normal common hook spanner of borrowing is finished its dismounting or terminal operation, and common hook spanner is made up of the semi-annular shape bayonet socket of handle, handle one end disjunctor, the boss of semi-annular shape bayonet socket footpath inwardly protruding.During use, rectangular-shaped boss snaps in the outer round recessed of round helical product, and circle is close to the round nut cylindrical in the semi-annular shape bayonet socket, turns handle again, and boss drives round nut and rotates.Under this duty, spanner and round nut are in the same plane, so must there be the handle rotation space in the round nut periphery.But for all or part of occasion that sinks in the workpiece of nut, often, peripheral workpiece can't finish dismounting or fastening because stopping the gabarit of hook spanner, this often with the stub oblique cutting to nut groove and with hammering, nut is relatively rotated and locking or dismounting gradually, so operating efficiency low, be difficult to fastening or intact dismounting fully, damage nut easily.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of round nut profile spanner is provided.
Scheme of the present utility model comprises handle and semi-annular shape bayonet socket, the rectangular-shaped boss on the semi-annular shape bayonet socket; The circumferential width of described boss is slightly less than the groove that is provided with on the round nut cylindrical, it is characterized in that: semi-annular shape bayonet socket convex platform is a vertical boss to outer lug on semi-annular shape bayonet socket end face; Described boss is provided with three, and the boss phase difference is 90 degree, and is arranged on the two ends and the medium position of semi-annular shape bayonet socket semi-circumference.
Advantage of the present utility model is: for the restricted occasion of round nut peripheral space, two pin pawls of the both sides by profile spanner respectively by turns inserting on the distolateral groove of nut, rotate, thereby successfully realize dismounting or terminal operation.

Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the rearview of Fig. 1.
The specific embodiment:
The utility model comprises handle (3) and semi-annular shape bayonet socket (2), the rectangular-shaped boss (1) on the semi-annular shape bayonet socket (2); The circumferential width of described boss (1) is slightly less than the groove that is provided with on the round nut cylindrical, it is characterized in that: semi-annular shape bayonet socket (2) convex platform (1) is a vertical boss (1) to outer lug on semi-annular shape bayonet socket (2) end face; Described boss (1) is provided with three, and boss (1) phase difference is 90 degree, and is arranged on the two ends and the medium position of semi-annular shape bayonet socket (2) semi-circumference.
On corresponding another end face of three boss (1) end face of living in of semi-annular shape bayonet socket (2), be provided with two vertical boss (1) to outer lug, described two boss (1) phase difference is 90 degree, and these two boss (1) are 45 degree with three boss (1) phase difference of other end.
Boss (1) can be semi-annular shape bayonet socket (a 2) conjoined structure, also can be to be fixed on the semi-annular shape bayonet socket (2) with the pin form.
During operation, with the boss (1) of the one-sided or both sides of profile spanner respectively by turns inserting accordingly on the groove of the cylindrical of round nut, can separate or fastening it.
Claims (2)
1. the round nut profile spanner comprises handle (3) and semi-annular shape bayonet socket (2), the rectangular-shaped boss (1) on the semi-annular shape bayonet socket (2); The circumferential width of described boss (1) is slightly less than the groove that is provided with on the round nut cylindrical, it is characterized in that: semi-annular shape bayonet socket (2) convex platform (1) is a vertical boss (1) to outer lug on semi-annular shape bayonet socket (2) end face; Described boss (1) is provided with three, and boss (1) phase difference is 90 degree, and is arranged on the two ends and the medium position of semi-annular shape bayonet socket (2) semi-circumference.
2. round nut profile spanner according to claim 1, it is characterized in that on corresponding another end face of three boss (1) end face of living in of semi-annular shape bayonet socket (2), be provided with two vertical boss (1) to outer lug, described two boss (1) phase difference is 90 degree, and these two boss (1) are 45 degree with three boss (1) phase difference of other end.
