Abstract
The utility model belongs to the field of building construction tools and provides a stretching-in type bolt fastener which comprises a sleeve with a certain length and a nut nesting part arranged on the lower end portion of the sleeve. A nesting hole is formed in the nut nesting part. The nesting hole is matched with a nut which needs to be screwed in shape. According to the stretching-in type bolt fastener, the sleeve with the certain length stretches in a deep cavity, then the nut nesting piece is arranged on the nut in a sleeved mode, finally the sleeve is rotated, namely fastening operation is carried out on a bolt, construction procedures are simplified, and working efficiency is improved.
Description
Technical field
The utility model belongs to the construction field of tool, relates in particular to a kind of penetration type bolt tightener.
Background technology
At present, when dark chamber inner bolt is carried out to fastening construction, need offer handle hole in the cavity side, then by handle hole, spanner be stretched in cavity space and constructed; After bolted, then the orifice plate cut will offer handle hole time welding reduction.
There is following problem in the existing mode of offering the handle hole fastening bolt: need cut plate while 1, offering handle hole, increase working procedure.2, the handle hole size is narrow and small, and construction tool stretches into inconvenient operation after cavity, and efficiency of construction is low.3, need weld reduction to orifice plate, after the welding reduction, also need butt welded seam to be polished, detect a flaw, increase operation and engineering time.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of penetration type bolt tightener, is intended to solve in prior art the problem that operation is loaded down with trivial details, efficiency of construction is low existed when dark chamber inner bolt is carried out to fastening construction.
The utility model is to realize like this, a kind of penetration type bolt tightener, the nut nested unit that comprises the sleeve with certain-length and be arranged on described sleeve bottom, offer a nested hole on described nut nested unit, the shape in described nested hole is complementary with the nut shape that need tighten.
Further, described penetration type bolt tightener also comprises a screw limiting part, on described screw limiting part, offers a through hole, and the shape of described through hole and screw rod shape are complementary; Described screw limiting part is positioned at described sleeve bottom, and is positioned at described nut nest top, and described nested hole is through hole, and screw rod can pass described nested hole, enters described through hole.
Further, described nested Kong Chengzheng hexa-prism.
Further, described through hole is cylindric.
Further, described sleeve and described nut nest and/or screw limiting part are one-body molded.
Further, described bolt tightener also comprises handle, and described handle is arranged at the upper end of described sleeve.
Further, described sleeve removably is connected with described handle.
Further, described sleeve upper end offers that at least one pair of is axisymmetric to perforation, and described handle is installed on described sleeve perforation through described.
Further, described sleeve upper end offer two pairs described to perforation, described two pairs are crisscross arranged up and down to perforation, every a pair of in perforation, being equipped with a described handle.
Further, described handle is column.
The utility model compared with prior art, beneficial effect is: the sleeve that will have certain-length stretches in dark chamber, then the nut nest is set on nut, and last turn sleeve carries out fastening operation to bolt, simplify working procedure, improved operating efficiency.

Fig. 2 is the perspective view at another visual angle of penetration type bolt tightener shown in Fig. 1.
Fig. 3 is the perspective view of the screw limiting part of the penetration type bolt tightener shown in Fig. 1.
Fig. 4 is the perspective view of the nut nest of the penetration type bolt tightener shown in Fig. 1.
Fig. 5 be use the penetration type bolt tightener shown in Fig. 1 by fastening nuts the cross-sectional schematic on screw rod.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 to as shown in Fig. 4, for a preferred embodiment of the present utility model, a kind of penetration type bolt tightener, comprise the sleeve 1 with certain-length and the nut nested unit 2 that is arranged on sleeve 1 bottom, offer a nested hole 21 on nut nested unit 2, the shape in nested hole 21 is complementary with nut 3 shapes that need tighten.
Particularly, the penetration type bolt tightener also comprises a screw limiting part 4 and handle 5, offers a through hole 41 on screw limiting part 4, and the shape of through hole 41 and screw rod 6 shapes are complementary, and optimally, through hole 41 is columned through hole.Screw limiting part 4 is positioned at sleeve 1 bottom, and is positioned at nut nest 2 tops, and nested hole 21 is through hole, screw rod 6 can pass nested hole 21, enters through hole, optimally, this nested hole 21 is positive hexa-prism, and sleeve 1 is one-body molded with nut nest 2 and/or screw limiting part 4.Handle 5 is arranged at the upper end of sleeve 1, and sleeve 1 removably is connected with handle 5.Sleeve 1 upper end offers that at least one pair of is axisymmetric to boring a hole 11, and above-mentioned handle 5 is through 11 being installed on sleeve 1 boring a hole.Optimally, sleeve 1 upper end offers two pairs 11 being crisscross arranged up and down to boring a hole to boring a hole 11, two pairs, often a pair ofly to boring a hole in 11, is equipped with leader 5, and above-mentioned handle 5 is column.。
As shown in Figure 5, the sleeve 1 that will have certain-length stretches in dark chamber 7, then nut nesting part 2 is set on nut 3, the handle 5 that last turn is positioned at sleeve 1 upper end is about to nut 3 and is fastened on screw rod 6, penetration type bolt tightener in the present embodiment has been simplified working procedure, has improved operating efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
