Description

A kind of dual-purpose adjustable monkey wrench

Technical field

The utility model relates to a kind of spanner, and especially the tommy bar tail end is shaped on the dual-purpose adjustable monkey wrench of fork spanner spanner.

Background technology

In pipeline installation and repair work, often need come fastening or dismounting cylindricality parts with monkey wrench.But existing monkey wrench function singleness can only be twisted cylindrical component; For widely used bolt, nut, but can't turn.And existing monkey wrench is a hinged spanner on tommy bar, thereby can be according to the fastening or dismounting parts of opening angle of the size adjustment spanner of parts during use; But the opening angle of spanner has certain limitation, and the scope of application is less; When the change in size of parts is big, need to change the spanner of other specifications, waste time and energy, influence operating efficiency.

The utility model content

The purpose of this utility model is to overcome the problem that exists in the above-mentioned background technology, a kind of dual-purpose adjustable monkey wrench is provided, this monkey wrench should be able to be used for the disassemble and assemble work of screw bolt and nut, and have the minimizing instrument amount of carrying, easy to use, characteristics that the scope of application is bigger, to increase work efficiency.

The technical scheme that the utility model proposes is: a kind of dual-purpose adjustable monkey wrench comprises spanner, tommy bar and spanner is hinged on jointed shaft on the tommy bar; It is characterized in that: the rear portion of described spanner is shaped on regulating tank, and this regulating tank stretches along the length direction of spanner; Described jointed shaft passes the front end that is locked at described tommy bar behind the regulating tank, and other has a spring that acts on spanner and tommy bar respectively to be installed on the described jointed shaft; The tail end of described tommy bar is shaped on a fork spanner spanner.

The one side of described regulating tank cell wall is made the plane, and another side is shaped on several end to end arc surfaces, and this arc surface and mutual corresponding several cylindrical spaces of formation in described plane, is beneficial to jointed shaft and locatees the jaw that forms certain width in arbitrary arc surface.

The opening direction of described fork spanner spanner is level or is tilted to or is tilted to down.

Described jointed shaft is a T shape structure, and its main part is made the cylinder that cross section is an oval shape.

The front end of described tommy bar is shaped on and is used for the oval hole that jointed shaft interts.

Use principle of the present utility model is: when spanner and tommy bar opened with certain angle, the plane 2-1 on the jointed shaft (Fig. 9, shown in Figure 10) is parallel with the plane 6-1 of cell wall, and spanner can drive jointed shaft and slide in the regulating tank of tommy bar; When jointed shaft slides into correct position, clockwise rotate tommy bar and make the cylinder while of jointed shaft and two faces (arc surface 6-2 and plane 6-1) engagement of cell wall, form the pin joint of tommy bar and spanner; When jointed shaft rests on different arc surfaces, just can form the jaw of different in width; When needs assembling-disassembling bolt and nut, can use the fork spanner spanner of tommy bar tail end.

The beneficial effects of the utility model are: because the rear portion of spanner is shaped on regulating tank, makes the utility model can be suitable for the more part of large scale scope, thereby significantly enlarged range of application; And spanner is convenient to use, has improved operating efficiency, therefore has good market prospects.In addition, it is the fork spanner spanner that the circular hole (being used for hanging) of former tommy bar afterbody is changed a social system, to have the function of fork spanner; Like this, the utility model unites two into one the function of monkey wrench and fork spanner, has increased the purposes of spanner; And the change of being done is simple, and is easy to make.

The specific embodiment

Below, the technical solution of the utility model is described further by Figure of description.

As shown in Figure 1, a kind of dual-purpose adjustable monkey wrench comprises spanner 1, tommy bar 5 and spanner is hinged on jointed shaft 2 (as Fig. 9, shown in Figure 10, this jointed shaft is a T shape structure, and its main part is made the cylinder that cross section is an oval shape) on the tommy bar.

The rear portion of described spanner is shaped on the regulating tank 6 that stretches along its length direction, and the front end of described tommy bar is shaped on and is used for the oval hole 5-2 (shown in Figure 4) that jointed shaft 2 interts; Jointed shaft is locked on the described tommy bar by a locking nut 2-2 (shown in Figure 9) after passing regulating tank and oval hole successively; Other has a spring 4 (shown in Figure 1) to act on spanner 1 and tommy bar 5 respectively, and this spring (helical spring) is enclosed within on the described jointed shaft 2, and an end of spring embeds and is installed in the groove 3 that is provided with on the tommy bar, and the other end is installed among the bar-shaped trough 1-1 at the spanner back side.The afterbody of described tommy bar 5 is shaped on fork spanner spanner 7, makes the utility model also have the function of fork spanner, and the dimensions of fork spanner spanner is determined according to required nut engaged.

The one side of described regulating tank cell wall is made plane 6-1, another side is shaped on several end to end arc surface 6-2, and this arc surface and mutual corresponding several cylindrical spaces of formation in described plane are beneficial to jointed shaft and locate the jaw that forms certain width in arbitrary arc surfaces.

The front end of described tommy bar is shaped on a boss 5-1, is used to prevent that spanner from rotating excessively (slewing area that limits spanner) under the effect of spring.The number of arc surface can be determined as required in the length of described regulating tank and the regulating tank, is 6 for the number of arc surface among the figure.

The opening direction of described fork spanner spanner can be as shown in the figure three kinds of shapes: promptly level is (as shown in Figure 1, the open centre line of fork spanner spanner is parallel with horizontal line), be tilted to (as shown in Figure 2, the open centre line of fork spanner spanner becomes an elevation angle with horizontal line) or be tilted to down (as shown in Figure 3, the open centre line of fork spanner spanner becomes an angle of depression with horizontal line); The angle that tilts can design as required voluntarily; Perhaps determine the shape of fork spanner spanner as required voluntarily.
