Description
Technical field
The utility model relates to the hardware ﹠ tools technical field, particularly a kind of pipe vice that is used for the installation or removal pipeline.
Background technology
The structure of existing pipe vice mainly is such, and it mainly comprises pincers handle, moving caliper and adjusting nut, and an end of pincers handle is provided with regular jaw, and the pincers handle is provided with the pincers cover, and the pincers cover is connected with the pincers handle by rivet; Adjusting nut is arranged in the pincers cover, and the back segment of moving caliper is inserted in the pincers cover, and the front end of moving caliper is provided with moving jaw, and the moving caliper back segment is provided with screw thread, and the back segment of moving caliper is connected with adjusting nut by screw thread.In use, at first rotate adjusting nut, moving caliper is outwards moved, moving jaw is opened, then pipeline is placed between moving jaw and the regular jaw, then the reverse rotation adjusting nut, moving caliper is moved inward, until pipeline being clamped in moving jaw and the regular jaw; Pull the pincers handle then, just can reach the purpose of installation or removal pipeline.This pipe vice needs constantly rotation adjusting nut in use, operates loaded down with trivial detailsly, wastes time and energy.When pipe vice uses, put because nut can be pressed on pincers, thereby the pincers cover can bear bigger pressure, cause pincers covers cracking easily, phenomenons such as rivet distortion, thus influence service life of pipe vice.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of long service life is provided, and moving jaw is located conveniently pipe vice.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of pipe vice, comprise handle and movable fore paw, it is characterized in that: also comprise rear solid end pedestal, lock shaft, oval locking plate, the front end of rear solid end pedestal is provided with regular jaw, the handle front end is provided with gear, and this gear inserts rear solid end pedestal bottom; The front end of fore paw is provided with moving jaw, and the back segment of fore paw is the tooth bar that is complementary with gear, and this tooth bar inserts rear solid end pedestal top; Rear solid end pedestal sidewall is provided with locating slot, is provided with the elongated through hole in the locating slot, and lock shaft passes the elongated through hole and connects gear; Lock shaft one end is fixed with the first oval locking plate, and the other end connects the second oval locking plate by bolt, and oval locking plate places in the locating slot.
As further improvement of the utility model, locating slot top is circular trough, and the diameter of circular trough equates that with the major axis of oval locking plate the locating slot bottom is a deep-slotted chip breaker, and the major axis arc of the shape of this deep-slotted chip breaker and oval locking plate is suitable.
Regular jaw and moving jaw place are equipped with anti-skidding line.
Oval locking plate is provided with lock and refers to groove.Convenient finger is stirred oval locking plate.
Overlap rubber sleeve on the handle.In the use, can prevent that hand and handle from sliding.
Oval locking plate can slide in locating slot, and when the major axis arc of oval locking plate was positioned at deep-slotted chip breaker, oval locking plate driven gear moved down, and this moment, gear and fore paw back segment were separated.Behind pipe vice clamping pipeline, regular jaw on the rear solid end and the moving jaw on the fore paw are held pipeline tightly, regulate the fore paw position, stir oval locking plate, make on the oval locking plate to move in the circular trough, this moment, the major axis arc of oval locking plate broke away from deep-slotted chip breaker, moved on the lock shaft driven gear, wheel and rack carries out meshing, and the position of fore paw is fixed.As long as stir lock-bit or the release that oval locking plate just can be finished fore paw gently, it is very convenient quick, time saving and energy saving to operate.
Form because the rear solid end pedestal is whole, anti-extrusion ability is strong, can not rupture long service life because of the extruding that is subjected to lock shaft.
Regular jaw and moving jaw place are equipped with anti-skidding line, can not slide when jaw is held pipeline tightly like this, also can avoid the scuffing to tube wall.The utility model can also use as adjustable wrench, carries out fastening or the dismounting nut.
In sum; the utlity model has following advantage: long service life; the moving jaw location is convenient and swift; the contact that jaw is held tightly behind the pipe is the line contact; so the active force to pipe can not produce a contact; pipe is stressed to be evenly distributed, non-slip, at utmost the protection tube sub-surface is not impaired.
