Description

Pipe tongs

Technical Field

The utility model relates to the field of machinary, a breakout tongs specifically says so.

Background

At present, the commonly used pipe tongs are mostly characterized in that a tong head is connected to a tong handle through a nut, the size of a tong opening is adjusted by rotating the nut, but when the opening of the tong opening is too large, the tong head is easy to fall off, and the operation is unsafe. Meanwhile, as the nut is arranged on the upper part of the clamp handle, the nut is screwed while the clamp handle is held by one hand when in use, and the operation is inconvenient.

Disclosure of Invention

In order to overcome the defects that the binding clip of the prior pipe wrench is easy to fall off and inconvenient to operate, the utility model provides a pipe wrench, the binding clip of which can not fall off, is safe to operate and is convenient to operate.

The technical scheme of the utility model is that: a pipe wrench comprises a pipe wrench seat, wherein the upper part of the pipe wrench seat is connected with a wrench head, the lower part of the pipe wrench seat is provided with a wrench handle, the front end of the wrench handle is connected with a nut after the wrench handle passes through the pipe wrench seat, and the nut is positioned in a clamping groove of the pipe wrench seat.

And a gasket is arranged between the pipe clamp seat and the clamp head.

The included angle between one side of each tong head and the horizontal direction is 60 degrees, and the included angle between the other side of each tong head and the horizontal direction is 12-30 degrees.

The front end of the forceps handle is provided with an inclined plane, the upper part of the inclined plane inclines forwards, and forceps teeth are arranged on the inclined plane.

The included angle of the clamp teeth of the clamp handle is 90 degrees, and the included angle of one side of the clamp handle and the horizontal direction is 60 degrees.

The included angle of the clamp teeth of the clamp handle is 90 degrees, and the included angle of one side of the clamp handle and the horizontal direction is 45 degrees.

The utility model discloses following beneficial effect has: by adopting the scheme, the binding clip of the pipe wrench is fixed with the wrench seat, so that the binding clip can be prevented from falling off; the adjusting nut is positioned below the clamp seat, so that the screwing of the nut is not influenced when one hand holds the clamp handle, and the operation is more convenient; the clamp teeth at the front end of the clamp handle are positioned on the inclined plane and can increase the clamping force after being matched with the clamp teeth of the clamp head, so that the clamping is firmer.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 to 5, a pipe wrench comprises a pipe wrench base 1, wherein a wrench head 2 is connected to the upper portion of the pipe wrench base 1, a gasket 5 is arranged between the pipe wrench base 1 and the wrench head 2, and the pipe wrench base 1 tightly clamps the pipe wrench base 1 and the wrench head 2. When the installation, put into the gap between pipe vice seat 1 and binding clip 2 with gasket 5 after, press the bending with 1 upper end edge of pipe vice seat to seal gasket 5 inside, like this, do not pull down gasket 5 then can't pull down binding clip 2, can avoid binding clip 2 to drop. The lower part of the pipe clamp seat 1 is provided with a clamp handle 3, the pipe clamp seat 1 is provided with a through hole parallel to the clamp head 2, and the front end of the clamp handle 3 is connected with a nut 4 after passing through the through hole. The lower part of the pipe clamp seat 1 is provided with a clamping groove, and the nut 4 is positioned in the clamping groove, so that the nut 4 can only rotate but can not move back and forth, and the nut 4 can be rotated to drive the clamp handle 3 to move forward and backward.

The forceps head 2 is provided with forceps teeth, as shown in fig. 3, an included angle between one side of each forceps tooth and the horizontal direction is 60 degrees, and an included angle a between the other side of each forceps tooth and the horizontal direction is 12-30 degrees. The front end face of the forceps handle 3 is an inclined plane, the upper part of the inclined plane is inclined forwards, the lower part of the inclined plane is backward, forceps teeth are arranged on the inclined plane, the forceps teeth can be of two structures, as shown in fig. 4 and 5, one of the forceps teeth has an included angle of 90 degrees, and the included angle of one side of the forceps teeth and the horizontal direction is 60 degrees; the other is that the included angle of the pincer teeth is 90 degrees, and the included angle of one side of the pincer teeth and the horizontal direction is 45 degrees. The inclination of the clamp teeth on the clamp handle 3 can increase the force of the pipe clamp for clamping the workpiece and increase the working torque at the same time by screwing the nut 4 with force after the clamp head 2 and the clamp handle 3 clamp the workpiece.
