Abstract
The utility model relates to booster pipe tongs, comprising a moving tong jaw (1), adjusting nuts (2), a tong body (3), pipe type tong handles (4), a conical locking block (5), a locking device (6) and booster rods (7). The inner holes on the end of the pipe type tong handles (4) are enlarged, the locking device (6) is processed with screw threads which are matched with the inner screw threads of the pipe type tong handles (4), and the booster rods (7) are arranged in the inner holes of the pipe type tong handles (4). The relative position between the booster pipe tongs and the object locked by the booster pipe tongs is not changed, and the utility model which is of safe use, of convenient operation and of portability is applied to different torque and different environments.
Description
Affiliated field:
The utility model relates to a kind of pipe vice, particularly a kind of afterburning pipe vice.
Background technology:
The boosting-rod of the afterburning pipe vice of present domestic use is to clamp by a fixing spring circle, like this, be subjected under the situation of axial thrust load, often change the length of boosting-rod, the operator uses dangerous, simultaneously, because boosting-rod flip-flop length, in use, casualty accident taking place easily, brings danger to the operator.
The invention task:
It is under any circumstance a kind of that the purpose of this utility model will provide exactly, do not change the boosting-rod Len req, pipe vice easy to use, safe and reliable.
The purpose of this utility model is to realize like this, a kind of afterburning pipe vice, form by moving jaw (1) adjusting nut (2) caliper (3) tubular type pincers handle (4) boosting-rod (7) holes stifled (8), it is characterized in that the terminal endoporus of described tubular type pincers handles (4) strengthens, and is equipped with the screw-internal thread fit that cone locking piece (5) locker (6) car has external screw thread and tubular type pincers handles (4).
Optimum implementation of the utility model is that a middle taper oil injecting lubricating aperture (9) the oil injecting lubricating aperture (9) that is drilled with of the terminal endoporus stifled (8) of tubular type boosting-rod (7) is best in the middle of (8); Cone locking piece (5) is an open type, and endoporus is a straight hole, and profile is taper; Locker (6) is a garden pylon stepwise cover, and the centre is a through hole, and the outer garden of small end cylinder car has the screw-internal thread fit of external screw thread and tubular type pincers handles (4).
The utility model compared with prior art has following advantage:
Because the terminal endoporus of tubular type pincers handles (4) strengthens, and is equipped with the screw-internal thread fit that cone locking piece (5) locker (6) car has external screw thread and tubular type pincers handles (4), boosting-rod (7) is contained in the endoporus of tubular type pincers handle (4) cone locking piece (5) and locker (6); When adjusting the length of boosting-rod (7), only need tighten, unscrew locker (6); Thereby it is easy to use, safe and reliable.
Accompanying drawing and drawing explanation:
Figure: be the utility model concrete structure schematic diagram
1, moving jaw 2, adjusting nut 3, caliper 4, tubular type pincers handle
5, cone locking piece 6, locker 7, boosting-rod 8, plug
9, oil injecting lubricating hole
The specific embodiment:
Moving jaw (1) nut (2) caliper (3) tubular type pincers handle (4) cone locking piece (5) locker (6) boosting-rods (7) maybe can meet the requirements of other metal material processing with structural alloy steel and make.The terminal endoporus of tubular type pincers handles (4) strengthens, and car has internal thread, and cone locking piece (5) is an annular open type cone locking piece, and endoporus is a straight hole, and profile be a taper shape; Locker (6) is a cylinder table stepwise cover, and the centre is axial straight hole, and the small end car has external screw thread, holds annular knurl greatly, and the end of tubular type pincers handles (4) cooperates with boosting-rod (7) by cone locking piece (5) and locker (6) successively; The point diameter of boosting-rod (7) strengthens, and end is blocked with metal or plastics pole; Plug (8) is made with metal material or plastic processing, is drilled with oil injecting lubricating aperture (9) at the centre or the edge of plug (8).
During use latch segment, locker are inserted in from the end of boosting-rod, again the front end of boosting-rod are inserted the endoporus of tubular type pincers handles (4), unclamp locker (6) counterclockwise, adjust boosting-rod (7), tighten locker clockwise and can use to Len req.
Claims (4)
1, a kind of afterburning pipe vice is made up of moving jaw (1) adjusting nut (2) caliper (3) tubular type pincers handle (4) boosting-rods (7); It is characterized in that the terminal endoporus of described tubular type pincers handles (4) strengthens, and the screw-internal thread fit that latch segment (5) locker (6) car has external screw thread and tubular type pincers handles (4) is housed.
2, afterburning pipe vice according to claim 1 is characterized in that the center of the terminal endoporus plug (8) of described tubular type boosting-rod (7) has an oil injecting lubricating hole, oil injecting lubricating hole (9) (9) to be the best in the middle of the end of (7).
3, afterburning pipe vice according to claim 1 is characterized in that cone locking piece (5) is open type, and endoporus is a through hole, and profile is taper.
