Abstract
The utility model provides a combined pipe rotation wrench which is matched with a monkey wrench in order to substitute the a pipe wrench, comprising an outer sleeve which is composed by jointing two half blocks. The inner circumference of the outer sleeve is provided with teeth and wedge grooves, and is matched with wedge sheets and pins. The utility model has the advantages that the teeth has a plurality of engaging points with a pipe, the engaging points are uniform, the wrench head is handy, and the manufacture is material-saving.
Description
The utility model proposes a kind of spanner that can substitute the pipe vice turne tube.
The shortcoming of pipe vice commonly used is that pincers are few with the impetus of tooth interlock pipe, when interlock is not tight, skids easily, during the interlock tension, damages pipe again easily, moreover, the big heaviness of body, waste material.
Task of the present utility model provides a kind of combined type pipe with good, the light and handy material-saving of pipe interlock that can substitute pipe vice and rotates spanner.
Design of the present utility model is: a kind of combined type pipe rotates spanner, overcoat with an interior circular hole, the pipe cylindrical of circular hole and required rotation is equal or bigger in being somebody's turn to do, it is characterized in that this overcoat be divided into the equity on, following two parts, this two-part end is hinged, the other end is respectively established a pin hole, the circumference of the circular hole on overcoat top is provided with teeth, establish a wedge groove on the circumference of the circular hole of overcoat bottom, the bottom of wedge groove slightly tilts in the axial direction, and this wedge groove is furnished with a key, vertically in the wedge people wedge groove, in the axial direction, the length of key is greater than the wedge slot length.
Be described further below in conjunction with embodiment and accompanying drawing.
Fig. 1 is the part three-dimensional exploded view of embodiment.
Fig. 2 is the front view after the part assembling among Fig. 1.
Fig. 1, embodiment shown in Figure 2 have the overcoat that top 1 and bottom 10 by equity involute, and the pipe cylindrical that is with and required rotation outward equates or bigger interior circular hole.The at one end available rivet in overcoat top 1 and bottom 10 2 is hinged, rivet 2 passes behind the hinge hole 7 of top 1 and 10 ends, bottom through impacting, shape as shown in the figure, the other end is respectively established a pin hole 6, can use pin 5 to insert pin holes 6 and makes the top 1 of overcoat and bottom to synthetic complete overcoat.The circumference of the circular hole on overcoat top 1 is provided with teeth 3, establishes a wedge groove 4 on the circumference of the circular hole of overcoat bottom 10, and the bottom of wedge groove 4 slightly tilts in the axial direction, wedge groove 4 is furnished with a key 8, can wedge vertically in the wedge groove 4, in the axial direction, the length of key 8 is greater than the length of wedge groove 4.If the interior circular hole of overcoat is bigger, when promptly the pipe that is rotated is thick, can be provided with the teeth 9 relative on the key 8 with the teeth 3 on overcoat top 1.
The general employing of the outer rim of overcoat can use adjustable wrench to carry out the shape of rotation operation, as positive quadratic prism, and positive six prismatic and positive eight prisms.The overcoat edge also can be designed to cylindrical (figure does not show), is provided with several bar-inserting holes on the face of cylinder, inserts bar-inserting hole with excellent bar and also can carry out rotation operation.
Select corresponding combined type pipe to rotate spanner according to the specification of pipe, overcoat is straddled on pipe, after involutory, pin 5 inserts pin holes 6, pipe by obvolvent in overcoat, again key 8 is squeezed into wedge groove 4, as shown in Figure 2, can carry out operation, operation finishes and removes key 8, dial and remove pin 5, just removable spanner.
The utility model is compared with pipe vice, and teeth want many to the biting point of pipe, and evenly, spanner is light Ingeniously nimble, match with common monkey wrench, alternative pipe vice saves heavy clamp handle, has saved Material.
