Description

Quick-adjusting movable pipe vice wrench

The utility model relates to a kind of quick adjustment alligator wrench spanner, and it is the instrument of using always, is used for loading and unloading pipe fitting or threaded connector.

Common pipe wrench or adjustable wrench utilize worm and gear to come the width of adjustable pipe jaw or spanner mouth when loading and unloading pipe fitting or threaded connector, and its advantage is the width of accurate adjustable pipe jaw of energy or spanner mouth, and self-locking action is arranged; Its major defect is that governing speed is slow, inconvenient operation.Chinese patent 89202454.2 quick adjustment adjustable wrenches, the width of energy quick adjustment spanner mouth have the advantage of common adjustable wrench again, but it can only play spanner, can not work as pipe wrench.

The purpose of this utility model is that a kind of quick adjustment alligator wrench spanner will be provided, and the width of its energy quick adjustment pipe wrench mouth or spanner mouth not only can be worked as pipe wrench but also can work as spanner, and be had the advantage of common pipe wrench and adjustable wrench.

The purpose of this utility model is achieved in that on the basis of Chinese patent 89202454.2 quick adjustment adjustable wrenches, increases lower jaw assembly and upper jaw assembly.In the time will loading and unloading pipe fitting, with the upper jaw assembly Wrench head of packing into, and, replace moving jaw with the lower jaw assembly again near regular jaw, promptly be the quick adjustment pipe wrench.The lower jaw assembly is made up of lower jaw, jaw carriage, jaw pin and nut.Lower jaw is made of left plate, following engaging plate and right plate.Be processed with tooth on following engaging plate and the face that pipe fitting contacts.Lower jaw links to each other with the jaw carriage by jaw pin, nut.The jaw carriage is made of riser and following moving body.The contact-making surface of the following engaging plate of riser and lower jaw is an arc surface.Following moving body approximate circle cylinder, its top links to each other with riser, and its bottom is processed with the worm-gear toothing that is meshed with worm screw.The upper jaw assembly is made up of upper jaw, compression spring and ball.Upper jaw is made of last engaging plate, connecting plate and last moving body.Be processed with tooth on last engaging plate and the face that pipe contacts, the medial surface of its back side and regular jaw is closely connected.Last moving body approximate circle cylinder, its side are equipped with compression spring and ball.

The utility model is because of having increased spanner mouth (pipe wrench mouth) quick adjustment mechanism, so the width of energy quick adjustment pipe wrench mouth or spanner mouth has advantage simple in structure, easy to operate, time saving; Because of increased lower jaw assembly and upper jaw assembly on the basis of quick adjustment adjustable wrench, it both can work as adjustable wrench usefulness, can work as pipe wrench usefulness again again, was a kind of multi-purpose tool.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the structure chart of quick adjustment alligator wrench spanner when the adjustable wrench time spent.

Fig. 2 is the structure chart of quick adjustment alligator wrench spanner when the pipe wrench time spent.

Fig. 3 a is the A-A cutaway view of Fig. 3 b lower jaw assembly.

Fig. 3 b is the side view of Fig. 3 a lower jaw assembly.

Fig. 4 a is the front view of upper jaw assembly.

Fig. 4 b is the side view of Fig. 4 a upper jaw assembly.

Further specify structure of the present utility model and principle below in conjunction with accompanying drawing.Fig. 1 is that quick adjustment alligator wrench spanner is worked as the adjustable wrench structure chart of (the outspoken velocity modulation joint of spanner mechanism adopts worm screw side rotation structure) time spent, and it mainly is made up of the outspoken velocity modulation joint of moving jaw (1), regular jaw (4), Wrench head (2), spanner handle (3) and spanner mechanism.It is characterized in that having increased on common adjustable wrench the outspoken velocity modulation joint of spanner mechanism, it comprises worm screw (6), worm shaft (7), support (8), support shaft (9) and spring wire (10).The outspoken velocity modulation of whole spanner joint mechanism is installed on the Wrench head (2) by support shaft (9), and utilizes the elastic force of spring wire (10), makes worm shaft (7) place two support grooves on the Wrench head (2).When wanting the width of quick adjustment spanner mouth, hold up worm screw (6) with finger, worm screw (6), worm shaft (7) are rotated around support shaft (9) with support (8), worm screw (6) throws off with the worm-gear toothing of moving jaw (1) bottom, promote moving jaw (1) fast, it is moved in jaw shifting chute (5), but the then distance of quick adjustment moving jaw (1) and regular jaw (4), the i.e. width of quick adjustment spanner mouth.When finger does not hold in the palm worm screw (6), under the elastic force effect of spring wire (10), worm shaft (7) places two support grooves of Wrench head (2), and the worm screw (6) and the worm-gear toothing of moving jaw (1) bottom are meshed, and rotary worm (6) gets final product the width of Micro-regulating wrench mouth.

Fig. 2 is the structure chart that quick adjustment alligator wrench spanner is worked as the pipe wrench time spent, and it mainly is made up of the outspoken velocity modulation joint of lower jaw assembly (1), upper jaw assembly (4), regular jaw (5), Wrench head (2), spanner handle (3) and pipe wrench mechanism.The outspoken velocity modulation joint of pipe wrench mechanism still is made up of worm screw (6), worm shaft (7), support (8), support shaft (9) and spring wire (10), and its action principle is identical with the outspoken velocity modulation joint of the spanner among Fig. 1 mechanism.The main distinction of Fig. 2 and Fig. 1 is: loaded onto upper jaw assembly (4) at the medial surface of regular jaw (5), replaced original moving jaw with lower jaw assembly (1).

The structure of lower jaw assembly is seen Fig. 3 a and Fig. 3 b, and it is made up of lower jaw (1), jaw carriage (2), jaw pin (8) and nut (7).Lower jaw (1) is by left plate (5), and following engaging plate (4) and right plate (6) are formed.Be processed with tooth on following engaging plate (4) and the face that pipe fitting contacts, be used for biting the surface of pipe fitting.Lower jaw (1) links to each other with jaw carriage (2) by jaw pin (8), nut (7).Jaw carriage (2) is made up of riser (9) and following moving body (10).Riser (9) is an arc surface with the contact-making surface (3) of the following engaging plate (4) of lower jaw (1), and during the loading and unloading pipe fitting, lower jaw (1) can be made fine rotation around jaw pin (8), so that the surface that the tooth of following engaging plate (4) is bitten pipe fitting better.The structure of following moving body (10) is identical with the polycrystalline substance of moving jaw among Fig. 1, can in the jaw shifting chute of Wrench head, move, and its approximate circle cylinder, top links to each other with riser (9), and the bottom is processed with the worm-gear toothing that is meshed with worm screw.

The structure of upper jaw assembly is seen Fig. 4 a and Fig. 4 b, and it is made up of upper jaw (1), compression spring (2) and ball (3).Upper jaw (1) is made of last engaging plate (4), connecting plate (5) and last moving body (6).Be processed with tooth on last engaging plate (4) and the face that pipe fitting contacts, be used for biting the surface of pipe fitting, its back can be closely connected with the medial surface of regular jaw.Last moving body (6) approximate circle cylinder can move in the jaw shifting chute of Wrench head.The upper jaw assembly slides in the jaw shifting chute in order to prevent to load and unload pipe fitting, and compression spring (2) and ball (3) are housed in the side of last moving body (6).

When the outspoken velocity modulation joint of the spanner of quick adjustment adjustable wrench mechanism adopts the worm screw moving structure, also can increase above-mentioned lower jaw assembly and upper jaw assembly, constitute quick adjustment alligator wrench spanner.
