Abstract

The utility model provides a fast and fine adjustable pipe wrench with the functions of fast adjustment and fine adjustment, which can fast and accurately adjust the size of wrench mouths. The pipe wrench can be formed by the way that the wrench head threads of the pipe wrench widely used presently can be eliminated a part (in another embodiment, the threads are reserved without elimination), and a nut is processed with a fast adjusting mouth. The nut is turned at the time of work, when the fast adjusting mouth is exactly faced the wrench head threads, the wrench head can be pushed out or pulled in for completing the fast adjustment, and then the nut can be turned for the fine adjustment.

Description

Quick vernier monkey wrench

The utility model relates to a kind of pipe vice, particularly a kind ofly can regulate the pipe vice of jaw size according to pipe diameter rapidly accurately.

The pipe vice of extensive use at present mainly is made up of binding clip, pincers handle, adjusting nut etc., does not have velocity modulation mechanism, can only finely tune.When changing jaw size, can only realize by the rotation adjusting nut.This control method, though accurately and reliably, when pipe diameter changes greatly, too slow, hell to pay.

The purpose of this utility model is: a kind of pipe vice is provided, and when changing jaw size, can velocity modulation, can finely tune again.

Task of the present utility model realizes as follows: the screw thread of adjusting nut is removed a part, and binding clip belly (or back) screw thread also removes (in another embodiment, belly and back screw thread all do not remove).When changing jaw size, rotate adjusting nut, make its unthreaded portion, at this moment binding clip is released or drawn in, carry out velocity modulation, rotate adjusting nut then and finish fine setting over against the binding clip screw thread.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is the pipe vice longitudinal sectional drawing that adjusting nut and binding clip all remove a part of screw thread.

Fig. 2 is the profile of Fig. 1 along the A-A line.

Fig. 3 is the pipe vice longitudinal sectional drawing that only the adjusting nut screw thread is removed a part.

Fig. 4 is the profile of Fig. 3 along the B-B line.

1-binding clip among the figure, the 2-graduation mark, the 3-adjusting nut, 4-back screw thread, 5-anticreep bolt, 6-clamps handle, and 7-transfers mouth soon, 8-belly screw thread, 9-strengthens adjusting nut, and 10-deepens the fast mouth of transferring.

With reference to Fig. 1, remove a part of screw thread of adjusting nut (3), form fast transfer mouthful (7), its width is slightly larger than the thickness of binding clip (1), and height is a little more than the tooth height of screw thread.Remove binding clip (1) belly screw thread (8), keep back screw thread (4); Perhaps remove back screw thread (4), keep belly screw thread (8).

In the embodiments of figure 3, remove and strengthen a part of screw thread of adjusting nut (9), forms fast transfer mouthful (10), its width is slightly larger than the thickness of binding clip (1), highly a little more than 2 times tooth height.Binding clip (1) belly and back screw thread all keep.

During operation, at first rotate adjusting nut (3) or strengthen adjusting nut (9), make and transfer mouthful (7) or deepen fast transfer mouthful (10) ［ in the embodiments of figure 3 soon over against the screw thread of binding clip (1), make the nut axial line depart from two high distances of tooth of binding clip screw thread axial line ］, at this moment binding clip (1) has lost the locking of screw thread, retractable, binding clip (1) released or draw in carry out velocity modulation, the graduation mark (2) that exposes when binding clip (1) is basic when being consistent with pipe diameter, rotate adjusting nut (3) or increasing adjusting nut (9) again and finely tune, till pipe vice blocks pipe firmly.

In trim process, make nut axial line and binding clip axial line keep overlapping, block in order to avoid meet during rotation.When carrying out work by pressing tongs handle (6), avoid fast and transfer mouthful (7) and deepen fast transfer mouthful (10) over against back screw thread (4), be in locked state so that guarantee binding clip (1).

The utility model is made simple, uses flexibility and reliability.

Claims

1, one by binding clip (1), pincers handle (6), strengthen the quick fine setting pipe vice that adjusting nut (9) is formed, it is characterized in that strengthening and have to deepen the fast mouth (10) of transferring on the adjusting nut (9).

2, according to the described pipe vice of claim 1, it is characterized in that deepening the fast width of mouthful (10) of transferring and be slightly larger than binding clip (1) thickness, height is a little more than 2 times tooth height.

3,, it is characterized in that binding clip (1) has back screw thread (4) not have belly screw thread (8) according to the described pipe vice of claim 1; Perhaps there is belly screw thread (8) not have back screw thread (4).

4, according to the described pipe vice of claim 1, it is characterized in that adjusting nut (3) has fast transfer mouthful (7), its width is slightly larger than binding clip (1) thickness, and height is a little more than the tooth height of screw thread.
