Abstract

本实用新型涉及一种螺栓安装紧固领域,特别涉及一种适用于紧固螺栓长度突出螺母20mm以上的专用螺母紧固扳手,包括圆筒状的内六方工作部分,所述内六方工作部分的横截面为与六角螺母外表面相配合的六边形,其特征在于:所述内六方工作部分的长度不小于20毫米,所述内六方工作部分上方焊接有圆筒状的加长部分,所述加长部分的上端对称开设有两Φ12.5横向通孔,所述横向通孔内安装有加长杆。本实用新型克服现有技术中存在的普通套筒扳手在紧固M20螺母时无法旋紧螺母的缺点提供一种实现对螺栓超出螺母20mm以上的六角螺母包装紧固的专用螺母紧固扳手。

The utility model relates to the field of bolt installation and fastening, in particular to a special nut tightening wrench suitable for fastening bolts with a length protruding from the nut by more than 20mm, comprising a cylindrical inner hexagonal working part, the inner hexagonal working part The cross section is a hexagon that matches the outer surface of the hex nut, and it is characterized in that: the length of the inner hexagonal working part is not less than 20 mm, and a cylindrical extension part is welded above the inner hexagonal working part, and the lengthening The upper end of the part is symmetrically opened with two Φ12.5 transverse through holes, and an extension rod is installed in the transverse through holes. The utility model overcomes the disadvantage that the common socket wrench in the prior art cannot tighten the nut when tightening the M20 nut, and provides a special nut tightening wrench for realizing the packaging and tightening of the hexagonal nut whose bolt exceeds the nut by more than 20mm.

Description

A kind of specialized nut spanner
Technical field
The utility model relates to a kind of bolt and installs fastening field, is particularly a kind ofly applicable to the specialized nut spanner that fastening bolt length gives prominence to more than nut 20mm.
Background technology
At present, in prior art, interior six side's working portions of general ordinary cartridge spanner are when fastening M20 nut, by the restriction of interior six side's degree of depth, when bolt protrudes more than nut 10mm, bolt withstands in spanner, and interior six aspects of box spanner fully cannot be contacted with nut, cannot tightening nut.
Summary of the invention
The purpose of this utility model is to overcome the ordinary cartridge spanner that exists in above-mentioned prior art cannot the shortcoming of tightening nut provide a kind of hex nut realizing exceeding bolt more than nut 20mm to pack fastening specialized nut spanner when fastening M20 nut.
The technical solution of the utility model is achieved in that and comprises cylindric interior six side's working portions, in described, the cross section of six side's working portions is the hexagon matched with hex nut outer surface, in described, the length of six side's working portions is not less than 20 millimeters, cylindric elongated portion is welded with above six side's working portions in described, the positional symmetry of the upper end distance end face 25 ~ 40mm of described elongated portion offers two Φ 12.5 ~ Φ 15 cross through hole, be provided with boosting-rod in described cross through hole, elongated portion 10 ~ 30mm is stretched out in boosting-rod one end.
Described interior six side's working portion length are 100mm, the Plate Welding composition adopting 2mm thick.
Described elongated portion employing length is that the steel pipe of 100mm is made.
The good effect that the technical solution of the utility model produces is as follows: specialized nut spanner of the present utility model, comprise cylindric interior six side's working portions, in described, the cross section of six side's working portions is the hexagon matched with hex nut outer surface, in described, the length of six side's working portions is not less than 20 millimeters, when fastening M20 nut, can not by the restriction of interior six side's working portion degree of depth, interior six aspects of spanner fully contact with nut, fast rotary jack panel, operating efficiency is high and screw effective; Be welded with cylindric elongated portion above six side's working portions in described, the upper end symmetry of described elongated portion offers two Φ 12.5 cross through hole, and be provided with extension bar in described cross through hole, the effect of extension bar makes to be convenient to screw reinforcing, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specialized nut spanner.
Fig. 2 is the cross-sectional structure schematic diagram of interior six side's working portions of the utility model specialized nut spanner.
Be labeled as in figure: 1, interior six side's working portions; 2, elongated portion; 3, boosting-rod.
Detailed description of the invention
A kind of specialized nut spanner, as Fig. 1, shown in 2, comprise cylindric interior six side's working portions 1, in described, the cross section of six side's working portions is the hexagon matched with hex nut outer surface, in described, the length of six side's working portions is 100 millimeters, when fastening bolt length gives prominence to the nut of more than nut 20mm, can not by the restriction of interior six side's working portion degree of depth, interior six aspects of spanner fully contact with nut, fast rotary jack panel, operating efficiency is high and screw effective, cylindric elongated portion 2 is welded with above six side's working portions in described, the positional symmetry of the upper end distance end face 25 ~ 40mm of described elongated portion offers two Φ 12.5 ~ Φ 15 cross through hole, there to be enough torsional strengths when using, boosting-rod 3 is installed in described cross through hole, about elongated portion 20mm is stretched out in boosting-rod one end, the other end tightens by hand afterburning position to maximize to reach screw-down torque, boosting-rod extension elongation can regulate according to the size of screw-down torque.
In cross through hole during operation, boosting-rod being inserted elongated portion, left and right screws, and the hex nut packaging realizing exceeding bolt more than nut 50mm is fastening.
Described interior six side's working portion length are 100mm, the Plate Welding composition adopting 2mm thick.
Described elongated portion employing length is that the steel pipe of 100mm is made.
The utility model is not limited only to use on various packaging is fastening, needs to carry out the occasion that bolt length gives prominence to more than nut 20mm all can well be applied at other.
