Abstract

A round-pipe spanner relates to tools of spanners for fastening or dismounting hexagon-head or square-head nuts and bolts, and is provided with a cylindrical pipe. A plurality of elongated circular spanner bayonets with two parallel opposite sides are arranged on the pipe wall of the cylindrical pipe, the two parallel opposite sides are connected through arc sides, distances between the two parallel opposite sides of the plurality of spanner bayonets correspond to nuts with different specifications respectively, and distances between two arc sides of the spanner bayonets are larger than the maximum size of corresponding nuts. According to the round-pipe spanner, the structure is simple and reasonable, the opening width is not needed to be adjusted, fewer materials and smaller space sizes are used, fastening and dismounting of bolts and nuts with more specifications are applicable, and working high above the ground or carrying outside is facilitated.

Description

A kind of pipe spanner

Technical field

The utility model relates to a kind of spanner kind tool fastening or dismounting turret head or square-head nut and bolt, a kind of specifically pipe spanner of being used for.

Background technology

At present; The main tool of fastening or demounting bolt, nut includes fork spanner and adjustable wrench, and these several kinds of spanners are widely used in daily life and work, but in use also can run into some inconveniences; The subject matter that exists has: monkey wrench will often be regulated A/F according to bolt, the nut of different size; Cross pine and skid easily, tension is difficult for taking off immediately after work, and efficient is lower; Fork spanner one is spanner only bolt, the nut of corresponding one or two specification, and it is subsequent use to be equipped with more spanner during for the bolt that loads and unloads a plurality of specifications, nut; Be to strengthen moment, handle is longer, and appearance and size is big, and weight is heavier in work high above the ground or when going out, and is not easy to carry; Material consumption is more in the manufacture process; When the bigger moment of needs, need add the sleeve lengthening arm of force, when family's use or out using, be difficult for finding the sleeve of suitable dimension.

The utility model content

The purpose of the utility model is the deficiency for solving the problems of the technologies described above; A kind of pipe spanner is provided, and it is simple and reasonable, need not regulate A/F; With material still less; Littler bulk can be suitable for the bolt of more specifications, the fastening and dismounting of nut, is convenient to work high above the ground or goes out carry.

The utility model is that to solve the problems of the technologies described above the technical scheme that is adopted be a kind of pipe spanner; Be provided with cylindrical tube; On the tube wall of cylindrical tube, be provided with a plurality of oblong spanner bayonet sockets, the spanner bayonet socket has two parallel opposite side, and two parallel opposite side connect through the circular arc limit; Distance in a plurality of spanner bayonet sockets between two parallel opposite side corresponds respectively to the nut of different model, and the distance between two arc limits of spanner bayonet socket is greater than the full-size of the nut of correspondence.

The beneficial effect of the utility model is: its simple in structure setting rationally, and intensity is high; Economical with materials, be easy to processing, can reduce cost; Be easy to carry, deposit; Spanner is with regard to bolt, the nut of applicable a plurality of specifications, and big if desired moment can be used boosting-rod; In the family or the environment of going out, rod member obtains than sleeve more easily, even one penetrate chopsticks behind the pipe also can the application of force; Therefore be fit to use under the family and the condition of going out; The bending strength of pipe is greater than the bending strength of the long-pending solid rod member of same material same cross-sectional, therefore can under identical stressing conditions, reduce material, and the spanner of a series of models is processed by the pipe of different-diameter; Can be nested together and deposit, can conserve space; Easy to operate, be suitable in factory, work high above the ground, family or multiple occasion such as go out are used.

Description of drawings

The structural representation of oblong slots on the top structure sketch map of Fig. 1 the utility model cylindrical tube and the cylindrical tube outer wall;

Mark among the figure: 1, cylindrical tube, 2, the spanner bayonet socket.

The specific embodiment

As shown in the figure, a kind of pipe spanner is provided with cylindrical tube 1; On the tube wall of cylindrical tube 1, be provided with a plurality of oblong spanner bayonet sockets 2, spanner bayonet socket 2 has two parallel opposite side, can after entangling the parallel opposite side of nut, impose moment; Reach the purpose of fastening and demounting bolt, nut, two parallel opposite side connect through the circular arc limit, and the distance in a plurality of spanner bayonet sockets 2 between two parallel opposite side corresponds respectively to the nut of different model; Distance between 2 two arc limits of spanner bayonet socket is greater than the full-size of the nut of correspondence, because the radian of cylindrical tube 1 itself and highly be more conducive to gripping of hand, therefore with respect to same length; But thin pinch bar is more conducive to apply power; For less bolt, nut, only use this instrument itself, manpower just can be fastening or dismounting; Bigger if desired moment can penetrate a boosting-rod to strengthen the arm of force in cylindrical tube 1.

It is simple and reasonable for the utility model; Need not regulate A/F, with material still less, littler bulk; Can be suitable for the bolt of more specifications, the fastening and dismounting of nut; Be convenient to work high above the ground or go out carry, when the needs lengthening arm of force, even still can find boosting-rod easily at home or under the outer artificial situation.

Claims

1. pipe spanner; It is characterized in that: be provided with cylindrical tube (1); On the tube wall of cylindrical tube (1), be provided with a plurality of oblong spanner bayonet sockets (2), spanner bayonet socket (2) has two parallel opposite side, and two parallel opposite side connect through the circular arc limit; Distance in a plurality of spanner bayonet sockets (2) between two parallel opposite side corresponds respectively to the nut of different model, and the distance between (2) two arc limits of spanner bayonet socket is greater than the full-size of the nut of correspondence.
