Abstract
The improvement discloses an improvement structure of pipe tongs. The improvement structure comprises a handle (1), a tong tooth (2), a rear tong tooth body (3), a locking shaft (4), a hinge shaft (5) and springs (6); the handle (1) and the tong tooth (2) are of an integrated structure; the tong tooth (2) can freely rotate and is connected with the rear tong tooth body (3) through the hinge shaft (5); one of the springs (6) is connected between the tong tooth (2) and the hinge shaft (5); the locking shaft (4) is connected onto the tong tooth (2) through the hinge shaft (5); the other spring (6) is arranged between the locking shaft (4) and the hinge shaft (5). According to the improvement structure of the pipe tongs, the tong tooth can rotate in any angle due to the match of the springs to form different sizes of cylindrical spaces with the rear tong tooth body so as to adapt to the requirements of different sizes of clamped objects and accordingly the use is flexible and meanwhile the tong tooth is provided with the locking shaft which is used for locking the position of the tong tooth automatically through the springs and accordingly the optimum clamping effect is achieved.
Description
Technical field
The utility model relates to pipe wrench field, particularly, relates to the improvement structure of pipe wrench.
Background technology
At present, turn bolt, nut, metal tube or other round piece and clamping or the sheet metal that fractures, cut off wire, all need to use respectively the series of tools such as monkey wrench, pipe vice and cutting pliers, these tool producing process complexity, can not one-object-many-purposes, in and cost high, be both uneconomically also not easy to keeping, use also inconvenient.And in petroleum machinery parts field, the accessory that often can use comprises pipe wrench.Old-fashioned pipe vice is to rely on nut to adjust pincers tooth to clamp the large primary nut of diameter once there is corrosion to be just difficult for regulating, and causes and uses inconvenience.We need a kind of adjustment-free pipe vice that is different from old-fashioned pipe wrench, and this pipe wrench has changed structure and the shape of old-fashioned pipe vice, there is no adjusting nut, thereby change the unfavorable factor that relies on nut to adjust clamping diameter.
Utility model content
The utility model has overcome the deficiencies in the prior art, the improvement structure of pipe wrench is provided, under the cooperation of spring, pincers tooth can rotate the cylindrical space that arbitrarily angled and forceps major tooth body form different sizes, to adapt to the needs of gripping objects of different sizes, use more flexible, in addition, on pincers tooth, be also provided with lock shaft by the position of spring automatic locking clencher tooth, reach best clamping effect.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: the improvement structure of pipe wrench, comprise handle, pincers tooth, forceps major tooth body, lock shaft, hinge axis and spring, described handle and forceps major tooth body are structure as a whole, described pincers tooth can rotate arbitrarily, pincers tooth is connected with forceps major tooth body by hinge axis, between pincers tooth and hinge axis, goes back linking springs; Described bearing pin is connected on pincers tooth by hinge axis, between bearing pin and hinge axis, spring is set.The anglec of rotation of pincers tooth, between 0-90 °, can not be skidded after guaranteeing to clamp.
Between described pincers tooth and forceps major tooth body, form a cylindrical cavity.Be convenient to clamp difform object.
The upper and lower surface of described handle is provided with rectangular groove.Handle adopts high-quality pucellas to make, and after heat treatment, assemblies, and guarantees the intensity of handle, and the design of groove, guaranteeing, under the prerequisite of handle strength, to have reduced the weight of pipe wrench, has alleviated workman's labour intensity.
The end of handle is set to arcuate structure and is provided with manhole in the end of handle.Guarantee operator's safety, avoid the end of handle to scratch workman, manhole is set and is convenient to management.
Described handle and lock shaft are adjacent.
Described bearing pin can move forward and backward on pincers tooth.Under the cooperation of spring, be convenient to the position of pincers tooth to carry out auto lock operation.
Compared with prior art, the beneficial effects of the utility model are:
1, in the utility model, clamp tooth and can rotate angle arbitrarily, and rotational angle is in rational scope, non-slip after guaranteeing to clamp, use more flexibly reliable, in addition, the design of lock shaft, can carry out auto lock to the position of pincers tooth, has further strengthened the reliability of its gripping objects.
2, handle of the present utility model adopts high-quality pucellas to make, in common operation, can there is not phenomenon of rupture, can effectively guarantee the personal safety of operating worker, handle upper and lower surface is wherein provided with square groove, guaranteeing under the prerequisite of handle strength, effectively alleviated the weight of pipe wrench, making pipe wrench weight is between the 2/3-1/2 of old-fashioned pipe wrench weight, has alleviated workman's work energy degree.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark and corresponding parts title in accompanying drawing: 1, handle; 2, pincers tooth; 3, forceps major tooth body; 4, lock shaft; 5, hinge axis; 6, spring.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but embodiment of the present utility model is not limited to this.
Embodiment 1:
Comprise handle 1, pincers tooth 2, forceps major tooth body 3, lock shaft 4, hinge axis 5 and spring 6, handle 1 is adjacent with lock shaft 4, and bearing pin 4 is connected on pincers tooth 2 by hinge axis 5, between bearing pin 4 and hinge axis 5, spring 6 is set.Handle 1 and the forceps major tooth body 3 of the present embodiment are structure as a whole, described pincers tooth 2 can rotate arbitrarily, pincers tooth 2 is connected with forceps major tooth body 3 by hinge axis 5, between pincers tooth 2 and hinge axis 5, goes back linking springs 6, between pincers tooth 2 and forceps major tooth body 3, forms a cylindrical cavity.Pincers tooth is wherein designed with the more suitable anglec of rotation, and scope, between 0-90 °, guarantees to coordinate clamping article can not skid between pincers tooth and forceps major tooth body.
The upper and lower surface of the handle 1 of the present embodiment is provided with rectangular groove, and the end of handle 1 is set to arcuate structure and is provided with manhole in the end of handle.Bearing pin 4 can move forward and backward on pincers tooth 2.
When use, according to the difference of object size shape, regulate pincers tooth to suitable angle, object is put in the cylindrical space that pincers tooth and forceps major tooth body surround, and then regulate lock shaft to insert the length of pincers tooth, play locking pliers tooth, can not skid after reaching clamping article, be convenient to the operation in later stage.Now only handle need be held, operation can be conveniently realized.Because adopting high-quality pucellas, makes by handle, upper and lower surface at handle is provided with groove, reducing under the prerequisite of pipe wrench quality, guarantee can not occur phenomenon of rupture in operation, can effectively guarantee operation and workman's personal safety, use safer, flexible, reliably and anti-skidding, improved operating efficiency.
As mentioned above, can realize preferably the utility model.
