Abstract
The utility model belongs to standard component general utility tool technical field, discloses a kind of staight shank bolt-locking spanner.Its technical characteristics is: comprise sleeve, is provided with that inwall is taper hole shape, outer wall is circular locking pressure ring in described sleeve, and the locking external diameter of pressure ring and the internal diameter of sleeve match.Staight shank bolt-locking spanner provided by the utility model, during locking staight shank bolt, the required screw screwed in is aimed in staight shank bolt thread side, opposite side puts into the taper hole of box spanner locking pressure ring, sleeve rotates by driving shaft that is pneumatic or electric tool, the frictional force of locking pressure ring is relied on to drive staight shank bolt to rotate, the thrust screwing in screw along with staight shank bolt increases, the frictional force of locking pressure ring and staight shank bolt increases, the degree of depth that staight shank bolt screws in screw increases, until screw in the degree of depth required.Its structure is simple, and practical, applied range, efficiency is high, can be used for every field.
Description
Technical field
The utility model belongs to standard component general utility tool technical field, particularly relates to the staight shank bolt-locking spanner that a kind of straight-bar bolt screws.
Background technology
The interior hexagonal of standard and outer-hexagonal bolt have general box spanner when screwing, and are equipped with electronic or pneumatic tool, are easy to bolt to screw.But staight shank bolt does not have turret head, a just through rod, general box spanner has no usage, and can only be screwed by craft by pipe wrench, and efficiency is low and the effect that screws is undesirable.Along with the development of high ferro technology, the application of bridge pad in bridge construction is more and more wider.Bridge pad is the intermediate binders of bridge body and bridge pier, carries the critical function of antidetonation, wind resistance, carrying.Together with the upper rivet clasp bolt of construction Bridge bearing is cast in bridge body, together with lower rivet clasp bolt is cast in bridge pier, wherein rivet clasp bolt is exactly a kind of staight shank bolt, one and concrete setting, one screws with the lower margin sleeve of bridge pad, rivet clasp bolt plays very important effect, and substantial amounts.Rivet clasp bolt screws in lower margin sleeve and has just become a difficult problem, and traditional mode adopts to screw by pipe wrench by hand, time-consuming, inefficiency, and quality is unstable.Thus the specific purpose tool that a kind of staight shank bolt screws is developed imperative, significant to the production efficiency improving whole industry.
Utility model content
The technical problems to be solved in the utility model is just to provide a kind of stable performance, and reliable in quality is simple and practical, operating efficiency high staight shank bolt-locking spanner.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise sleeve, is provided with that inwall is taper hole shape, outer wall is circular locking pressure ring in described sleeve, and the locking external diameter of pressure ring and the internal diameter of sleeve match.
Its additional technical feature is: described locking pressure ring is bonded in sleeve;
Described sleeve is hexagon-headed bolt locking sleeve.
Staight shank bolt-locking spanner provided by the utility model, during locking staight shank bolt, the required screw screwed in is aimed in staight shank bolt thread side, opposite side puts into the taper hole of box spanner locking pressure ring, sleeve rotates by driving shaft that is pneumatic or electric tool, the frictional force of locking pressure ring is relied on to drive staight shank bolt to rotate, the thrust screwing in screw along with staight shank bolt increases, the frictional force of locking pressure ring and staight shank bolt increases, the degree of depth that staight shank bolt screws in screw increases, until screw in the degree of depth required.Sleeve is conventional hexagonal-head bolt-locking sleeve, and locking pressure ring is circular, and material is polyurethane, and take full advantage of its elasticity and wearability, mould is compressing.The locking external diameter of pressure ring and the interior hex slot of sleeve match and use 502 gluingly to connect.Often kind of staight shank bolt-locking spanner can lock the staight shank bolt of several specification, and along with the increase of the staight shank diameter of bolt, the diameter of staight shank bolt-locking spanner also increases accordingly, and specification also increases accordingly.Staight shank bolt-locking spanner provided by the utility model, can meet staight shank bolt full thread, half-thread fastening requirements.Its structure is simple, and practical, applied range, efficiency is high, can be used for the every field such as bearing installation, machine-building, construction, can meet the requirement that every field staight shank bolt does not have Special rotary clamping tool.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model staight shank bolt-locking spanner.
Detailed description of the invention
Be described in further details below in conjunction with the concrete structure of accompanying drawing to the utility model staight shank bolt-locking spanner.
As shown in Figure 1, the utility model staight shank bolt-locking spanner comprises sleeve 1, is provided with locking pressure ring 2 in sleeve, and locking pressure ring 2 inwall is taper hole shape, outer wall is circular, the locking external diameter of pressure ring 2 and the internal diameter of sleeve 1 match, and locking pressure ring 2 is bonded in sleeve 1.
Staight shank bolt-locking spanner provided by the utility model, during locking staight shank bolt 3, the required screw screwed in is aimed in staight shank bolt 3 screw thread side, opposite side puts into the taper hole of box spanner locking pressure ring 2, sleeve 1 rotates by driving shaft 4 that is pneumatic or electric tool, the frictional force of locking pressure ring 2 is relied on to drive staight shank bolt 3 to rotate, the thrust screwing in screw along with staight shank bolt 3 increases, locking pressure ring 2 increases with the frictional force of staight shank bolt 3, the degree of depth that staight shank bolt 3 screws in screw increases, until screw in the degree of depth required.Sleeve 1 is conventional hexagonal-head bolt-locking sleeve, and locking pressure ring 2 outer wall is circular, and material is polyurethane, and take full advantage of its elasticity and wearability, mould is compressing.The locking external diameter of pressure ring 2 and the interior hex slot of sleeve 1 match and use 502 gluingly to connect.Often kind of staight shank bolt-locking spanner can lock the staight shank bolt 3 of several specification, and along with the increase of staight shank bolt 3 diameter, the diameter of staight shank bolt-locking spanner also increases accordingly, and specification also increases accordingly.
Staight shank bolt-locking spanner provided by the utility model is not limited only to above-mentioned form, but no matter is adopt which kind of form, as long as structure is identical with the utility model, all falls into protection domain of the present utility model.
