Abstract
The utility model discloses a multi-purpose double offset ring spanner, which belongs to a hand tool. One multi-purpose double offset ring spanner can screw hexagon nuts of various specifications. The whole quantity can be reduced by a half. Besides, the multi-purpose double offset ring spanner also keep the traditional function of a double offset ring spanner. The multi-purpose double offset ring spanner comprises a handle, cylindrical spanner heads arranged on the two ends of the handle, etc. Each end of the spanner heads are provided with two holes of which shapes are similar with the double offset ring holes of a traditional double offset ring spanner. Besides, the two holes are overlapped and communicated on a shaft line. The utility model has the advantages of simple structure, reasonable design and easy application.
Description
How this belongs to the hand-operated tools class with double offset ring spanner.
Traditional double offset ring spanner, though design is fairly perfect, the quantitative range that turns hex nut is too little, one the hex nut that can only turn two specifications.Will be equipped with manyly the spanner of different size during work, the transposing spanner number of times that operates is frequent, is difficult for selecting, and influences operating efficiency.Since the increase of quantity, the corresponding increase of manufacturing cost, metal material consumption is big, and waste is serious.A whole set of Heavy Weight, it is very inconvenient to carry.
The present invention only needs traditional double offset ring spanner is changed slightly, just can realize: one many hex nuts with rotatable four different sizes of double offset ring spanner.Played one many effects that are equivalent to two traditional double offset ring spanners with double offset ring spanner.Simultaneously the quantity of spanner has reduced half, selects very conveniently during operation, reduces the transposing number of times, increases work efficiency.Alleviate a whole set of weight, carry convenient.
These are many with double offset ring spanner as shown in the figure.
By driving end (1); Handle (2); Formations such as plum blossom hole (3), (4).The truncated cone-shaped (also can make cylindrical) that is shaped as dribbling shape of driving end (1).Handle (2) is a staight shank, and its section is oval.Plum blossom hole (3), (4) are arranged on the driving end, and two holes are respectively polygonal hole clocklike, and two holes are overlapping communicating on same axis, two angles of each Kong Youshi (5), and angle is 120 °, and 12 angles are uniform on same circumference.Should equate angular distance with the theory of setting hex nut angular distance.The hex nut specification that respectively be inserted on the driving end two sides of any end of spanner is preferably approaching, is beneficial to the wall thickness of control driving end, and two holes (3), (4) degree of depth of overlapping on the same axis respectively account for 1/2nd of driving end thickness.It is fixed that the thickness of driving end can come according to the specification of setting hex nut, generally is advisable at 15mm to 30mm.
This is how simple, reasonable in design with plum wrench structure, its economy, and convenient, reliable, practicality etc. all is that traditional double offset ring spanner is incomparable.
These many instantiations with double offset ring spanner are as follows, and this example is that the rotation hex nut is the example of 27.7mm and 31.2mm to angular distance.
As shown in the figure:
1, the maximum gauge of driving end (1) is 38mm, and thickness is 24mm.
2, hole (3) and hole (4) on same axis, overlapping communicating, hole depth is respectively 12mm.
3,12 angles (5) of hole (3) are uniform on same circumference, are 31.2mm to angular distance.The angle at angle (5) is 120 °.
12 angles (6) in hole (4) are uniform on same circumference, are 27.7mm to angular distance.The angle at angle (6) is 120 °.
4, driving end is connected in aggregates with handle smoothly.
5, monnolithic case is molded with the instrument forging.
Can use the same method and design the other end of spanner.
Claims (2)
1, a kind of double offset ring spanners of using that can turn the hex nut of plurality of specifications more, it is characterized in that: it is by the first-class formation of spanner of the truncated cone-shaped (comprising cylindrical) of handle and dribbling shape, the two sides of driving end respectively is provided with the identical plum blossom hole that differs in size of shape, they are overlapping on same axis, and communicate.
2, according to claim 1ly use double offset ring spanner, it is characterized in that: plum blossom hole is made up of 12 angles more, and its angle is 120 ° ± 2 °
