Description

Movable anticreep antiskid F type valve spanner

Technical Field

The invention relates to the technical field of wrenches, in particular to an F-shaped wrench.

Background

The F-shaped wrench is a very common tool in the technical field of valve opening and closing, is a special wrench for increasing torque for opening a valve conveniently, has a shape very similar to that of an English letter F, and is widely applied to opening and closing various hand wheel type valves.

When the F-shaped wrench is used, the following points should be noted: (1) firstly, the door wheel should be firmly clamped to prevent the door wheel from being disengaged; (2) the operator should separate two feet and the sole of the foot stand stably, and the two legs are reasonably supported to prevent falling down; (3) the operator should hold the handles tightly with both hands and exert force reasonably and uniformly to prevent violent force or violence; (4) the handle of the valve wrench is in the same horizontal plane with the door wheel, so that the force of the valve wrench is reasonably applied to the door wheel, and the door wheel is prevented from being damaged due to excessive force.

The existing F-shaped valve wrench on the market is designed with valve wrenches corresponding to different model standards according to different occasions and different sizes of valves. However, in production practice, it is often the case that the existing F wrenches are still not perfectly well addressed.

When a hand wheel on a manual stop valve is operated on a production site, if one of the situations that a valve rod of the valve is lack of oil and rusts, the valve hand wheel has no spokes, the pressure difference between the front and the back of the valve is too large, the valve hand wheel is too large and the like exists, the phenomenon that an operator is injured due to inertia is frequently seen when a wrench is used for operating the valve with large force and the valve wrench slides away from the hand wheel.

Disclosure of Invention

In order to solve the above technical problems, an object of the present invention is to provide a valve wrench capable of clamping a valve and preventing the valve from falling off.

The technical scheme of the invention is as follows:

the utility model provides a movable anticreep antiskid F type valve spanner, includes handle (1), first banquet (2), second banquet (3), first banquet (2) are connected handle (1) tip, second banquet (3) are connected handle (1) lateral wall, handle (1) with be the F type after first banquet (2), second banquet (3) are connected, its characterized in that:

a plate head thread part (32) is arranged on the second plate head (3), a nut (4) is connected onto the plate head thread part (32), a rod (5) is welded on the outer wall of the nut (4), and the length of the rod (5) is smaller than the distance between the first plate head (2) and the second plate head (3).

Furthermore, a plurality of threaded openings (51) are formed in the outer wall of the rod (5) facing the handle (1).

Further, the length of the rod (5) is one half of the distance between the first and second plates (2, 3).

Furthermore, the first plate head (2) and the second plate head (3) are both vertically connected with the handle (1), and the first plate head (2) and the second plate head (3) are parallel at the same side of the handle (1).

Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Referring to fig. 1, a movable anti-slip F-shaped valve wrench according to a preferred embodiment of the present invention includes a handle 1, a first plate 2 and a second plate 3, the first plate 2 is connected to an end of the handle 1, the second plate 3 is connected to a side wall of the handle 1, the handle 1 is F-shaped after being connected to the first plate 2 and the second plate 3, specifically, the first plate 2 and the second plate 3 are both vertically connected to the handle 1, the first plate 2 and the second plate 3 are parallel to each other on a same side of the handle 1, and the first plate 2 and the second plate 3 are both connected to the handle 1 by welding. The above mentioned are common wrenches, and the lengths of the first and

second plates

2 and 3 are the same.

The invention is characterized in that a plate thread part 32 is arranged on the second plate head 3, a nut 4 is connected on the plate thread part 32, a rod 5 is welded on the outer wall of the nut 4, and the length of the rod 5 is smaller than the distance between the first plate head 2 and the second plate head 3. The left and right ends of the second plate 3 are respectively provided with a wrench connecting part 31, the part is directly welded with the handle 1, and the wrench outer part 33 is smooth and is positioned at the end part of the second plate 3.

And a plurality of screw ports 51 are provided on the outer wall of the lever 5 on the side toward the handle 1, the screw ports 51 having a screw width larger than that of the screw portion 32.

The length of the rod 5 is preferably half of the distance between the first plate 2 and the second plate 3, and this length is obtained through many tests, and in practice, the length is not more than the distance between the first plate 2 and the second plate 3.

In the invention, the outer sides of the handle 1, the first plate head 2 and the second plate head 3 are coated with anticorrosive paint, so as to improve the anticorrosive performance of the whole device.

The preparation method specifically comprises the following steps:

weld first ban head 2 to the tip of handle 1 on, start screw thread portion in the middle part of second ban head 3, grind the outer wall of spanner connecting portion 31 and make its diameter that is less than screw thread portion, can conveniently sheathe the nut like this, like this because the outside diameter of spanner is great, the nut can not fall from the ban head outside, then with on ban head connecting portion welded connection to handle 1, on the outer wall of again with pole welded connection to nut, spout anticorrosive paint to whole device at last, accomplish the preparation.

The working principle of the invention is as follows:

when putting the F spanner and operating on valve 100 hand wheel, the quarter butt alright come the adjustment suitable position through the nut rotation, block the hand wheel, it is not right to apply during the operation people stand the position or the valve card is dead hard and the spanner breaks away from the condition emergence of hurting operating personnel etc. to prevent, and the used power is fixed radially simultaneously, helps laborsaving.

When operating some good operating valves, because quarter butt welds with the nut and dies, can be along with the 360 rotations of nut, so can adjust quarter butt and the spanner body of rod apart from increasing, also can adjust the quarter butt to spanner tail end direction, switch convenient nimble.

The invention has the following advantages:

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
