Abstract
The utility model discloses a fastening tool for a threaded connection piece. The fastening tool comprises a conversion spanner and a torque spanner, wherein a fastening fork hole is formed in one end of the conversion spanner; an insertion hole is formed in the other end of the conversion spanner; a connection hole corresponding to the insertion hole in the conversion spanner is formed in one end of the torque spanner; and the conversion spanner and the torque spanner are connected through connection pin shafts in the insertion hole and the connection hole. When the fastening tool is used, the fastening fork hole of the conversion spanner is clamped on a nut of the threaded connection piece to be fastened from one side, and the torque spanner is forcibly rotated to firmly fasten the threaded connection piece. 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 be sleeved on the nut for locking from the position above the threaded connection piece due to space limitation.
Description
Technical field
The utility model belongs to petrochemical equipment fixture technical field, particularly a kind of threaded connector 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 process of some bolted, be subjected to spatial constraints, the collet head of commercially available common torque spanner can't be enclosed within on nut from the top of bolt 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 threaded connector 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 threaded connector fastened tools, comprise conversion spanner and torque spanner, described conversion spanner one end is provided with fastening prong, the other end is provided with jack, torque spanner one end is provided with and changes the corresponding connecting hole of jack on spanner, and the bearing pin that is connected that the conversion spanner is connected with torque spanner 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 conversion spanner and torque spanner, described conversion spanner one end is provided with fastening prong, the other end is provided with jack, torque spanner one end is provided with and changes the corresponding connecting hole of jack on spanner, the bearing pin that is connected that the conversion spanner is connected with torque spanner in jack and connecting hole is connected, during use, be clamped on the fastening prong of conversion spanner on the nut of threaded connector to be tightened from a side, firmly the turning moment spanner is fastening firm with threaded connector, 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.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the structural representation of conversion spanner in Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and threaded connector fastened tools shown in Figure 3, it comprises conversion spanner 1 and torque spanner 2, left end at conversion spanner 1 is provided with fastening prong 3, right-hand member is provided with square jack 6, is provided with and changes the corresponding square connecting hole 4 of jack 6 on spanner 1 at torque spanner 2 left ends.Conversion spanner 1 is connected with torque spanner and is connected by the bearing pin 5 that is connected in jack 6 and connecting hole 4.
Fastening prong 3 is used for the chucking nut, and its large I is determined according to the specification of threaded connector to be tightened; The size of jack 6 and connecting hole 4 is determined according to the length dimension of torque spanner 2.
Use procedure of the present utility model is: 1, in limited space situation directly over threaded connector to be tightened, be clamped on the fastening prong 3 of changing spanner 1 on the nut of threaded connector to be tightened from a side; 2, turning moment spanner 2 firmly, until with threaded connector fastening firm till; 3, taking off tool from the nut of threaded connector.
