Abstract
The utility model discloses a bolt inspection tool for narrow and small space, including torque wrench and ordinary spanner, ordinary spanner's middle part is provided with a spliced pole, the side of the ordinary spanner of spliced pole perpendicular to, torque wrench's inspection end is provided with the locating hole that the section is regular polygon, and the outer wall of spliced pole is regular polygon, and the spliced pole stretches into the locating hole and links to each other with the locating hole. Through set up a spliced pole on ordinary spanner, and this spliced pole is connected with the torque wrench, this length that has just increased the torque wrench can go deep into narrow and small space to can reach the bolt of examining. During inspection, one end of the common wrench, which is far away from the torque wrench, is sleeved on the detected bolt, and then acting force is applied to the torque wrench.
Description
Technical Field
The utility model relates to a field, concretely relates to bolt inspection tool for narrow and small space.
Background
In the process of reporting and testing tightness quality of steel structure bolts, the bolts are large in quantity and wide in distribution, some bolts can be in extremely narrow gaps, hands are difficult to stretch into the bolts, the length of a conventional torque wrench is limited, the bolts needing to be detected are difficult to reach, the detection is very inconvenient, and the working efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a bolt inspection tool for narrow and small space is provided to the elasticity of the bolt in the narrow and small space of inspection.
The utility model provides a technical scheme that technical problem adopted is: a bolt inspection instrument for narrow and small space, including moment spanner and ordinary spanner, the middle part of ordinary spanner is provided with a spliced pole, the side of the ordinary spanner of spliced pole perpendicular to, moment spanner's inspection end is provided with the locating hole that the section is regular polygon, and the outer wall of spliced pole is regular polygon, and the spliced pole stretches into the locating hole and links to each other with the locating hole.
Further, the connecting column is a screw cap.
Further, the connecting column is connected with a common spanner in a welding mode.
Furthermore, the checking end of the torque wrench is provided with a sleeve, and the positioning hole is formed in the sleeve.
Compared with the prior art, the beneficial effects of the utility model are that: through set up a spliced pole on ordinary spanner, and this spliced pole is connected with the torque wrench, this length that has just increased the torque wrench can go deep into narrow and small space to can reach the bolt of examining. During inspection, one end of the common wrench, which is far away from the torque wrench, is sleeved on the detected bolt, and then acting force is applied to the torque wrench.
Drawings
FIG. 1 is a schematic view of the present invention;
reference numerals: 1-torque wrench; 2-a common wrench; 3, connecting a column; 4, positioning holes; and 5, sleeving.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
The utility model discloses a bolt inspection instrument for narrow and small space, as shown in fig. 1, including torque wrench 1 and ordinary spanner 2, the middle part of ordinary spanner 2 is provided with a spliced pole 3, the side of the ordinary spanner 2 of spliced pole 3 perpendicular to, torque wrench 1's inspection end is provided with the locating hole 4 that the section is regular polygon, and the outer wall of spliced pole 3 is regular polygon, and spliced pole 3 stretches into locating hole 4 and links to each other with locating hole 4.
The general wrench 2 may be a conventional ring spanner or open spanner, and has connecting holes at both ends for fitting bolts, wherein one end can be used for holding by hand. The moment wrench 1 adopts the prior art, one end of the moment wrench is provided with an inspection end, and the inspection end is provided with a positioning hole 4 which can be matched with a bolt; the other end of the torque wrench 1 is a force application end for applying force.
The connecting column 3 is used for connecting the common wrench 2 and the torque wrench 1, so that the length of the torque wrench 1 is increased, and the torque wrench 1 can be extended further to reach the tested bolt. The connecting column 3 can be a hexagonal prism, and correspondingly, the positioning hole 4 is a regular hexagonal hole. In addition, the connecting column 3 can also be directly screwed and fixed on the common wrench 2 by welding. Ordinary spanner 2 generally is the less platelike of thickness, has the side of two broad, and the side of spliced pole 3 perpendicular to broad guarantees moment spanner 1's effort and passes through behind spliced pole 3 and the ordinary spanner 2 when transmitting to the bolt under test, and is unanimous with the effort direction to ordinary spanner 2 when directly adopting moment spanner 1 to guarantee the accuracy that detects.
The positioning hole 4 can be welded with the connecting column 3, and the positioning hole 4 can also be sleeved on the connecting column 3 to form a detachable connecting structure. In order to improve the connection stability of the positioning hole 4 and the connecting column 3, the checking end of the torque wrench 1 is provided with a sleeve 5, and the positioning hole 4 is arranged in the sleeve 5. The length of the sleeve 5 is larger than the thickness of the torque wrench 1, so that the matching length of the force positioning hole 4 and the connecting column 3 is larger, and the connection stability is better.
When detecting, overlap sleeve 5 on spliced pole 3, make ordinary spanner 2 link to each other with moment spanner 1, the end of exerting force of handheld moment spanner 1 puts into narrow and small space with ordinary spanner 2 covers on being surveyed the bolt, then exerts through the end of exerting force of moment spanner 1 and detects power to being surveyed the bolt.
The utility model discloses simple structure adopts conventional moment spanner 1 and ordinary spanner 2 can make, and the preparation is convenient, and the implementation cost is low.
