Abstract
The invention discloses pipe tongs for mounting and dismounting pipes. The pipe tongs mainly comprise a tong handle provided with a fixed tong mouth, a tong sleeve riveted with the tong handle, a movable tong body arranged in the tong sleeve, a movable tong mouth arranged at one end of the movable tong body, a rack arranged on the movable tong body, a tooth block arranged in the tong handle, wherein the tong block is elastically meshed with the rack. During the use of the pipe tong, as long as the tooth block is pressed down to separate from the rack, the movable tong mouth is made to slide down to form the largest opening; while when a pipe is placed between the movable tong mouth and the fixed tong mouth, as long as the end part of the movable tong mouth is beaten slightly inward, the pipe is clamped between the movable tong mouth and the fixed tong mouth tightly. The operation is extremely simple and quick. In addition, the tooth block is arranged directly in the tong handle, so the tong sleeve and a rivet do not withstand force substantially and can not be damaged, and the service life of the pip tongs is improved greatly.
Description
Technical field
The present invention relates to the hardware ﹠ tools field, refer more particularly to and wherein be used for the pipe vice of installation or removal pipeline.
Background technology
Since pipe vice comes out, the structure of tradition pipe vice is as described below always, it mainly comprises: the pincers handle, one 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, be provided with moving caliper and adjusting nut in the pincers cover, one end of moving caliper is provided with moving jaw, and moving caliper is provided with screw thread, and the screw thread on the moving caliper matches with adjusting nut.The using method of the pipe vice of said structure is: at first to a certain direction rotation adjusting nut, moving caliper is outwards moved, moving jaw is opened, pipeline is placed between moving jaw and the regular jaw then, reverse rotation adjusting nut again, 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.The shortcoming of above-mentioned pipe vice is: one, when needs clamp or unclamp pipeline, need constantly rotate adjusting nut, operate more loaded down with trivial details, time-consuming also longer; Two,, when using pipe vice, put, thereby clamp cover and bearing bigger pressure, easily cause the phenomenon that the pincers cover ftractures, rivet is out of shape, thereby have influence on the service life of pipe vice because nut can be pressed on to clamp.
Summary of the invention
At the problems referred to above, the present invention will provide that a kind of operation is simple more, the pipe vice of longer service life.
For achieving the above object, the technical solution used in the present invention is: described pipe vice mainly comprises: the pincers handle, one end of pincers handle is provided with regular jaw, the pincers handle is provided with the pincers cover, the pincers cover is connected with the pincers handle by rivet, also be provided with moving caliper in the pincers cover, an end of moving caliper is provided with moving jaw; On moving caliper, also be provided with tooth bar, be provided with the tooth piece in the handle at pincers, the tooth piece can with the tooth bar Elastic Meshing, in the pincers handle, also be provided with spring, an end of spring contacts with the tooth piece, the elastic force of spring can make tooth piece and the mutual Elastic Meshing of tooth bar.
Advantage of the present invention is: one, owing to be provided with the structure that the tooth piece is meshed with tooth bar, during use, only need by the lower tooth piece tooth piece and tooth bar to be separated, just can make under the moving jaw to slide into maximum open; After pipeline being put between moving jaw and the regular jaw, only need inwardly pat the end of moving jaw, just can immediately pipeline be clamped in moving jaw and the regular jaw, operate very simple, quick; Two, because the tooth piece is set directly in the pincers handle, thereby pincers cover and rivet do not stress basically when using, and just can not sustain damage, and have improved the service life of pipe vice greatly.
Description of drawings
Fig. 1 is the front view of pipe vice of the present invention;
Fig. 2 cuts open the structure enlarged drawing that clamps cover back A part among Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments technical solutions according to the invention and operation principle thereof and advantage are further described.
As shown in Figure 1, pipe vice of the present invention mainly comprises: pincers handle 1, and an end of pincers handle 1 is provided with regular jaw 5, pincers handle 1 is provided with pincers cover 9, pincers cover 9 is connected with pincers handle 1 by rivet 4, also is provided with moving caliper 7 in the pincers cover 9, and an end of moving caliper 7 is provided with moving jaw 6; On moving caliper 7, also be provided with tooth bar 2, be provided with tooth piece 3 in the handle 1 at pincers, tooth piece 3 can with tooth bar 2 Elastic Meshing.In the present embodiment, tooth piece 3 both sides are provided with projection, and projection is given prominence in the outside of pincers cover 9, and the purpose that projection is set is: be convenient to grip when operation tooth piece 3.
As shown in Figure 2, in the present embodiment, also be provided with spring 11 in pincers handle 1, an end of spring 11 contacts with tooth piece 3, and the elastic force of spring 11 can make tooth piece 3 and tooth bar 2 mutual Elastic Meshing.
The using method of pipe vice of the present invention is: when needs clamping pipeline, only need by lower tooth piece 3 tooth piece 3 and tooth bar 2 to be separated, make moving jaw slide into maximum open 6 times; Then pipeline is put between the moving jaw of opening 6 and regular jaw 5, inwardly patted the end of moving jaw 6 again, just pipeline can be clamped in moving jaw 6 and the regular jaw 5.When needs unclamp pipeline, only need tooth piece 3 and tooth bar 2 to be separated by lower tooth piece 3, the certain distance of moving jaw 6 downslides is got final product, operate very simple, quick; In addition, in the present embodiment, because tooth piece 3 is set directly in the pincers handle 1, thereby pincers cover 9 and rivet 4 do not stress basically when using, and just can not sustain damage yet, and this has improved the service life of pipe vice greatly.
As shown in Figure 1, in the present embodiment, on pincers cover 9, also offer watch window 8; As shown in Figure 2, on moving caliper 7, also be provided with line size graduation mark 10.Such setting can be known the diameter dimension of the pipeline of clamping in actual use easily.
Claims (2)
1, pipe vice mainly comprises: the pincers handle, 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, also is provided with moving caliper in the pincers cover, and an end of moving caliper is provided with moving jaw; It is characterized in that: on moving caliper, also be provided with tooth bar, be provided with the tooth piece in the handle at pincers, the tooth piece can with the tooth bar Elastic Meshing, in the pincers handle, also be provided with spring, an end of spring contacts with the tooth piece, the elastic force of spring can make tooth piece and the mutual Elastic Meshing of tooth bar.
2, pipe vice as claimed in claim 1 or 2 is characterized in that: put at pincers and also offer watch window, also be provided with the line size graduation mark on moving caliper.
