Abstract
The utility model discloses a fastening tool for an inner hexagonal bolt. The fastening tool comprises an inner hexagonal spanner, a torque spanner and a converter, wherein a longitudinal insertion hole and a horizontal inner hexagonal mounting hole are formed in the converter; a connection hole corresponding to the insertion hole in the inner hexagonal spanner is formed in one end of the torque spanner; the inner hexagonal spanner is inserted into the inner hexagonal mounting hole; and the torque spanner and the converter are connected through connection pin shafts in the insertion hole and the connection hole. When the fastening tool is used, the front end of the inner hexagonal spanner is placed in the inner hexagonal part of the inner hexagonal bolt, and the torque spanner is forcibly rotated to firmly fasten the inner hexagonal bolt. The fastening tool is simple in structure, flexible to use, wide in application range and simple and convenient to operate, and effectively solves the difficult problem that a sleeve head cannot sleeve a nut for locking from the position above a threaded connection piece due to space limitation.
Description
Technical field
The utility model belongs to petrochemical equipment fixture technical field, particularly a kind of hexagon socket head cap screw fastened tools.
Background technology
In the petroleum chemical engineering construction, because being subjected to surrounding enviroment, equipment component affects, and its installing space is narrow and small especially, and this has just increased the installation difficulty of equipment.Particularly in the situation that will increase torque spanner in the fastening process of some hexagon socket head cap screws, be subjected to spatial constraints, operation inconvenience, commercially available common inner hexagon spanner can't be put into from the top of hexagon socket head cap screw to be tightened at all, causes being difficult to complete the locking to bolt.
The utility model content
The utility model provide a kind of simple in structure, use hexagon socket head cap screw fastened tools flexible, applied widely and easy and simple to handle.
For achieving the above object, the technical solution of the utility model is: a kind of hexagon socket head cap screw fastened tools, comprise inner hexagon spanner, torque spanner and conversion head, described conversion head is provided with jack and horizontal interior hexagonal installing hole longitudinally, torque spanner one end be provided with inner hexagon spanner on the corresponding connecting hole of jack, inner hexagon spanner is inserted in interior hexagonal installing hole, and the bearing pin that is connected that torque spanner is connected with conversion head in jack and connecting hole is connected.
Described jack and connecting hole are square.
compared with prior art, the utility model has the advantages that: the utility model comprises inner hexagon spanner, torque spanner and conversion head, described conversion head is provided with jack and horizontal interior hexagonal installing hole longitudinally, torque spanner one end be provided with inner hexagon spanner on the corresponding connecting hole of jack, inner hexagon spanner is inserted in interior hexagonal installing hole, the bearing pin that is connected that torque spanner is connected with conversion head in jack and connecting hole is connected, during use, the front end of inner hexagon spanner is put into the hexagonal of hexagon socket head cap screw to be tightened, firmly the turning moment spanner is fastening firm with hexagon socket head cap screw, it is simple in structure, use flexibly, applied widely, easy and simple to handle, efficiently solve because being subjected to the spatial constraints collet head to be enclosed within the difficult problem that nut is completed locking from the threaded connector top.
