Abstract
The utility model relates to an adjustable self-locking pipe tong which is a hand tool used for connecting threaded pipes, comprising a *shaped tong body, a handle whose one end forms an arc shape to compose a jaw and a connector used for connecting the tong body and the handle. The utility model has the advantages of reasonable and simple structure, convenient portability and operation and wide range of applications, which is difficult for the pipe to generate deformation and is the ideal tool for the plumber and the pipeliner.
Description
The present invention is a kind of pliers, especially for a kind of pipe vice of connecting thread junction block.
For the pipe vice that overcomes existing strap bolt and the existing complex structure of American pipe vice, Heavy Weight, deficiencies such as inconvenience are carried in use, application number is to have proposed a kind of self-locking type pipe wrench again in China's patent application of 87102730, this pipe vice has overcome the weakness of above two kinds of pipes, and its advantage of union is on the one.But, owing to constitute the stationary structure of the Jiong clamp body of upper jaw, limited the scope of its suitable caliber, therefore, have to this pipe vice is made all size, to adapt to different calibers.So neither save material, inconvenience is collected and is carried again.
The objective of the invention is: provide a kind of caliper long adjustable, suitable wide self-locking type pipe wrench of caliber scope.
The object of the present invention is achieved like this: with a connector ┌ clamp body and an end are curved circular-arc, as to constitute lower jaw handle and link up, connector is a property with handle and connects, both can relatively rotate round connecting pivot pin, the other end of connector, be enclosed within on the arm of ┌ clamp body, and can move thereon, fixing on a certain position by an adjusting tight mechanism of rope and its.
This design is owing to adopted connector, the upper jaw and the lower jaw of caliper are linked up, changed the sort of Jiong clamp body of having fixed its spacing, it is adjustable that its spacing is become, like this, more strengthen the scope of its suitable caliber, reduced the specification of pipe vice, comparatively speaking, reduced cost, saved raw material.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the front view of adjustable self-locking formula pipe vice.
Fig. 2 is the vertical view of adjustable self-locking formula pipe vice.
Fig. 3, the B of adjustable self-locking formula pipe vice is to cutaway view.
With reference to Fig. 1, Fig. 2, Fig. 3, with the unsealed shaped as frame connector in lower end ［ 2 ］, be enclosed within on the arm of ┌ clamp body ［ 1 ］, the vice jaw surface ［ 4 ］ that protrude on both sides lug boss on the connector ［ 2 ］ and caliper ［ 1 ］ both sides matches, connector ［ 2 ］ can not be moved up and down on the arm of caliper ［ 1 ］, can only horizontally slip.The lower end of connector ［ 2 ］ is stuck on the pincers handles ［ 3 ］, with bearing pin ［ 5 ］ it is linked up, and makes connector ［ 2 ］ and pincers handles ［ 3 ］ can center on bearing pin ［ 5 ］ and relatively rotates.Along continuous straight runs has some adjustment holes ［ 6 ］ on the arm of ┌ clamp body, with pin ［ 7 ］, by the circular hole of connector ［ 2 ］ upper center, passes adjustment hole ［ 6 ］ and locks.Move the position of connector ［ 2 ］ to another adjustment hole ［ 6 ］ along the arm of caliper ［ 1 ］, and with pin ［ 7 ］ locking, the just relative position between adjustable jaws body ［ 1 ］ and the connector ［ 2 ］ is with suitable different caliber.
Adjustment hole ［ 6 ］ can be through hole, the relative position between caliper ［ 1 ］ and the connector ［ 2 ］ fixing, and available front end has the pin ［ 7 ］ of pin-and-hole, passes the circular hole on through hole ［ 6 ］ and the connector ［ 2 ］, uses pin ［ 8 ］ to inject pin-and-hole then and locks.
Adjustment hole ［ 6 ］ also can be a circular hole or a groove that has silk mouthful, with screw pin ［ 7 ］, passes the circular hole on the connector ［ 2 ］, is screwed in the silk mouthful and locks.
Earlier connector ［ 2 ］ is moved on to position suitable, that can be suitable for certain caliber along caliper ［ 1 ］ during use, with regulating retaining mechanism locking, again caliper ［ 1 ］ is buckled on the tube body ［ 9 ］ then, rotate handle ［ 3 ］, just can use.
