Description
Technical field
The present invention relates to the hardware ﹠ tools field, especially, relate to a kind of bolt pair locking tool.
Background technology
Bolt pair is a kind of the most basic five metals coupling assembling, screw bolt and nut, consists of; When connecting handware, bolt pass on two connected pieces over against screw, make the nut of bolt push down the surface of one of them connected piece, then, by the operator with nut from the screw on screw rod of bolt of a side of another connected piece.In aforesaid operating process, present generally operation is to clamp the nut of a side with a spanner, live again the nut of opposite side with another spanner or restraining sleeve, then the spanner at hold-doun nut place, the spanner at rotating nut place or sleeve, bolt pair locking the most at last.
, for above-mentioned bolt pair lock mode, need to adopt two instruments, in the both sides of connected piece, carry out respectively; Its operation is trouble very, inefficiency, and, in some poor operating positions, can't operate at all.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of bolt pair locking tool, this bolt pair locking tool can be locked bolt pair in a side of bolt pair, and easy and simple to handle, efficiency is higher.
The technical scheme that technical solution problem of the present invention adopts is: this bolt pair locking tool comprises handle, and described handle front end is fixedly connected with a center-pole, and the front end of described center-pole is shaped with a screw thread running-on with internal thread; Described center-pole outside cover has a swivelling pipe that can rotate around center-pole; The front end of described swivelling pipe is shaped with a nut running-on; The screw thread of the bolt of described screw thread running-on and locked bolt pair is complementary; The nut periphery of described nut running-on and locked bolt pair is complementary; Described screw thread running-on, nut running-on are the counterbore type; Described screw thread running-on is opposite with respect to the tightening direction of described bolt with described nut.
, as preferably, be also threaded engagement between described swivelling pipe and described center-pole; Like this, when fixing described center-pole, and while rotating described swivelling pipe, the screw thread pair between swivelling pipe and center-pole will give swivelling pipe a thrust forward by force, thereby be more conducive to make the nut of locked bolt pair to overcome advance resistance.
As preferably, offer at least one transverse holes on the tube wall of described swivelling pipe, and described bolt pair locking tool also sets the assister bar that at least one and described transverse holes are complementary, thereby assister bar can be inserted in described transverse holes, easily rotates described swivelling pipe.
As preferably, described handle is magnetic section at the end near described center-pole, and described swivelling pipe consists of ferromagnetics, thereby makes described bolt pair locking tool when not working, and swivelling pipe can be attracted by handle, and is difficult to come off.
As preferably, the outer surface of described swivelling pipe is shaped with anti-skidding lines, so that operation.
As preferably, the counterbore degree of depth of described nut running-on is 0.5～0.9 times of the nut thickness that matches.
beneficial effect of the present invention: this bolt pair locking tool in use, at first the screw thread running-on of described center-pole front end tentatively is screwed onto on the screw thread of bolt, then with the nut sleeve muzzle of described swivelling pipe to the nut outside, when rotating this swivelling pipe, nut rotates with swivelling pipe, at this moment, if not transfer of bolt, nut will move to the nut end gradually, if bolt transfer, because described screw thread running-on is opposite with respect to the tightening direction of described bolt with nut, therefore, bolt will go deep into the screw thread running-on gradually, until prop up the counterbore bottom of screw thread running-on, at this moment, bolt again transfer in swivelling pipe, thereby swivelling pipe can be locked nut and bolt reliably, this bolt pair locking tool can be locked bolt pair in a side of bolt pair, and easy and simple to handle, efficiency is higher.
Description of drawings
Fig. 1 is embodiment one schematic diagram of this bolt pair locking tool.
Fig. 2 is that the A of Fig. 1 embodiment is to schematic diagram.
Fig. 3 is embodiment two schematic diagrames of this bolt pair locking tool.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment one:
In Fig. 1, embodiment one shown in Figure 2, this bolt pair locking tool comprises handle 1, and described handle 1 front end is fixedly connected with a center-pole 2, and the front end of described center-pole 2 is shaped with a screw thread running-on 20 with internal thread; Described center-pole 2 outsides covers have one can be around the swivelling pipe 3 of center-pole 2 rotations; The front end of described swivelling pipe 3 is shaped with a nut running-on 30; Described screw thread running-on 20 is complementary with the screw thread of the bolt of locked bolt pair; Described nut running-on 30 is complementary with the nut periphery of locked bolt pair; Described screw thread running-on 20, nut running-on 30 are the counterbore type; Described screw thread running-on 30 is opposite with respect to the tightening direction of described bolt with described nut.
In the present embodiment, the counterbore degree of depth of described nut running-on 30 is 0.5～0.9 times of the nut thickness that matches, like this, both can steadily entangle nut, and does not hinder nut and be close to the connected piece surface; The outer surface of described swivelling pipe 3 is shaped with anti-skidding lines, so that operation.
In the present embodiment, as preferably, described handle 1 is magnetic section 11 at the end near described center-pole 2, and described swivelling pipe 3 consists of ferromagnetics, thereby makes described bolt pair locking tool when not working, and swivelling pipe 3 can be attracted by handle 1, and is difficult to come off.
In addition, can be threaded engagement between described swivelling pipe 3 and described center-pole 2, be shaped with screw thread pair 23 between them; Like this, when fixing described center-pole 2, and while rotating described swivelling pipe 3, the screw thread pair between swivelling pipe 3 and center-pole 2 will give swivelling pipe 3 one thrusts forward by force, thereby be more conducive to make the nut of locked bolt pair to overcome advance resistance.
Embodiment two:
Figure 3 shows that embodiments of the invention two, the difference of itself and embodiment one is: offer transverse holes on the tube wall of described swivelling pipe 3, and described bolt pair locking tool also sets an assister bar 4 that is complementary with described transverse holes, after assister bar 4 inserts in described transverse holes, rotary arm increases, so can easily rotate described swivelling pipe 3.
the bolt pair locking tool that the present invention relates in use, at first the screw thread running-on 20 of described center-pole 2 front ends tentatively is screwed onto on the screw thread of bolt, then the nut running-on 30 of described swivelling pipe 3 is overlapped to the nut outside, when rotating this swivelling pipe 3, nut rotates with swivelling pipe 3, at this moment, if not transfer of bolt, nut will move to the nut end gradually, if bolt transfer, because described screw thread running-on 20 is opposite with respect to the tightening direction of described bolt with nut, therefore, bolt will go deep into screw thread running-on 20 gradually, until prop up the counterbore bottom of screw thread running-on 20, at this moment, bolt again transfer in swivelling pipe 3, thereby swivelling pipe 3 can be locked nut and bolt reliably, this bolt pair locking tool can be locked bolt pair in a side of bolt pair, and easy and simple to handle, efficiency is higher.
The foregoing is only preferred mode of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
