Description
Technical field
The utility model relates to a kind of anchor clamps of field of mechanical technique, particularly a kind of rotary pulling force locking pipe vice.
Background technology
Current general pipe vice all is to regulate with manual nut to lock jaw, because strength is limited, runs into very tightly or when pipe that year gets rusty for a long time and oil pipe, owing to pipe wrench can not be locked pipe and is at a complete loss as to what to do and pulls down; Or pipe need be got continuously very tight the time, because pipe wrench can not be locked pipe and also can't be gone up very tightly.
Through the literature search of prior art is found that Chinese utility model patent Granted publication day is on April 1st, 1998, Granted publication number is CN 2277323Y, and the patent No. is 96244246.1.This patent proposes a kind of pipe wrench that can exert pressure to jaw, concrete grammar is: by passing through hole on it in the end of deciding piece and motion block of common pipe wrench with T shape screw rod, groove, and screw with the swivel nut that has flexible handle, rotary handle comes jaw and workpiece are exerted pressure, it is unclamped in the other direction, thereby prevent that workpiece from skidding when work.Its deficiency is: 1, because flexible handle is to decide piece and motion block end at pipe wrench, hand to reach pipe wrench decide piece and rotary handle is removed to rotate in the motion block end, so meet the very complicated system of pipeline or under operating space very condition of limited, operate inconvenience.2, this patent requires the jaw profile consistent with the caught workpiece profile, thereby the scope of application also is limited.
Summary of the invention
The utility model is at the deficiencies in the prior art, a kind of rotary pulling force locking pipe vice is provided, make it apply the locking pulling force to jaw and workpiece by spanner, thereby prevent that workpiece from skidding when work, operating efficiency and security have been improved, and regulate the space above the pincers handle, thereby it is also unrestricted to regulate the space, the jaw profile is olecranon formula or three face contact types.
The utility model is achieved through the following technical solutions, the utility model is at the newly-increased nut seat in existing pipe wrench pincers handle back, nut seat has and the parallel internal thread through hole of pincers handle, screw thread is a trapezoidal thread, other increases when work and clamps the parallel hexagon-headed bolt of handle, the perforate of hexagon-headed bolt afterbody, hexagon-headed bolt passes in the through hole of nut seat during work, and the turret head nut is near pincers handle tail side, other increases by one and rotates channel-section steel, rotate the parallel axis that promptly rotates the channel-section steel bottom surface perpendicular to hexagon-headed bolt in channel-section steel bottom surface with the tail end face of moving jaw worm screw, rotate the channel-section steel two sides and have symmetrical two holes, the aperture is identical with hexagon-headed bolt afterbody aperture, when this three holes point-blank the time, T type latch can pass this three holes simultaneously, thereby can hexagon-headed bolt and rotation channel-section steel be coupled together by T type latch, rotating the channel-section steel bottom centre position links to each other with the connecting plate center by rivet, and keeping the 1mm gap that rotation channel-section steel flexible rivet is freely rotated, connecting plate is fixed on the end face of moving jaw worm screw by two screws of symmetry.
The utility model project organization is simple, technology maturation and cheap.Hexagon-headed bolt can be pulled down at ordinary times need not, when locking energetically or dismantle, needs connect again, because hexagon-headed bolt is on pincers handle top, so when adjusting hexagon-headed bolt with spanner, even in the very complicated system of pipeline, it is also unrestricted to regulate the space, and be to adjust hexagon-headed bolt with spanner, so can adjust the pipe wrench coupling mechanism force as required arbitrarily, thereby thoroughly lock pipe, avoid skidding.The utility model is easily manufactured, and it is simple to increase section construction.

Fig. 3 is the hexagon-headed bolt enlarged drawing
Among the figure: 1 is the pincers handle, and 2 is hexagon-headed bolt, and 3 is nut seat, and 4 is T type latch, and 5 is screw, and 6 is rivet, and 7 for rotating channel-section steel, and 8 is connecting plate, and 9 is the moving jaw worm screw, and 10 is adjusting nut, and 11 is moving jaw
The specific embodiment
As shown in Figure 1, the utility model comprises: pincers handle 1, hexagon-headed bolt 2, nut seat 3, T type latch 4, screw 5, rivet 6, rotation channel-section steel 7, connecting plate 8, moving jaw worm screw 9, adjusting nut 10, moving jaw 11.At the newly-increased nut seat 3 in existing pipe wrench pincers handle 1 back, nut seat 3 has and the parallel internal thread through hole of pincers handle 1, in addition newly-increased hexagon-headed bolt 2 that passes the through hole of nut seat 3, the nut of hexagon-headed bolt 2 is near pincers handle 1 rear side, and hexagon-headed bolt 2 afterbody perforates.As shown in Figure 2, other increases has one to rotate channel-section steel 7, rotate the parallel axis that promptly rotates channel-section steel 7 bottom surfaces perpendicular to hexagon-headed bolt 2 in channel-section steel 7 bottom surfaces with the tail end face of moving jaw worm screw 9, rotate position, channel-section steel 7 two sides and have symmetrical two holes, the aperture is identical with hexagon-headed bolt 2 afterbody apertures, when this three holes point-blank the time, T type latch 4 can pass this three holes simultaneously, thereby can hexagon-headed bolt 2 and rotation channel-section steel 7 be coupled together by T type latch 4, rotating channel-section steel 7 bottom centre positions links to each other with connecting plate 8 centers by rivet 6, and keep the 1mm gap that rotation channel-section steel 7 flexible rivets 6 are freely rotated, connecting plate 8 is fixed on the end face of moving jaw worm screw 9 by symmetrical up and down two screws 5, moving jaw worm screw 9 is an integral body with moving jaw 11, and adjusting nut 10 is nested on the screw rod of moving jaw worm screw 9.
Fig. 3 is the enlarged drawing of hexagon-headed bolt 2, and its afterbody is perforate.
As shown in Figure 1, beginning hand adjustment adjusting nut 10 allows moving jaw 11 clamping work pieces, and when adjusting nut 10 can not provide enough clamping force, available hexagon-headed bolt 2 passed the through hole that nut seat 3 contains internal thread.And as shown in Figure 2, the perforate of hexagon-headed bolt 2 afterbodys and the alignment of rotation two holes, channel-section steel 7 sides are point-blank, passing these three holes by T type latch 4 makes hexagon-headed bolt 2 link to each other with rotation channel-section steel 7, because rotating channel-section steel links to each other with connecting plate 8 by rivet 6 again, and connecting plate 8 is the end faces that are fixed on moving jaw worm screw 9 by screw 5, at this moment rotate hexagon-headed bolt 2 by spanner, hexagon-headed bolt 2 just can be by rotating channel-section steel 7 pulling moving jaws 11 with pipe locking, and the strength of locking can be regulated with spanner.When the locking purpose reaches, loosening or tighten pipe after, hexagon-headed bolt 2 can be withdrawed from, recover the usual function of pipe vice.
