The present invention relates to a pipe wrench that can be operated continuously, and in particular, it is possible to continuously operate the pipe to rotate continuously clockwise or counterclockwise according to the direction of the force applied to the handle when joining or detaching the pipe. It is about a pipe wrench.

In general, a pipe wrench is used to join or separate a gas pipe or a tap water supply pipe.

However, the problem of the conventional pipe wrench is to rotate the pipe clockwise or counterclockwise by using a wrench fixed in diameter to match the pipe diameter, so that the wrench cannot continuously transmit the rotational force to the pipe so that the wrench Slip on the outer peripheral surface of the pipe can not be rotated smoothly, as well as the problem of not being able to rotate the pipe continuously by the diameter of the adjustable wrench.

In addition, a pipe that prevents damage due to high pressure, such as gas pipes to form a separate coating film on the outer peripheral surface of the pipe, the wrench is not fixed to the outer peripheral surface of the pipe by the coating film formed on the outer peripheral surface of the pipe Since the slip does not smoothly rotate the pipe, as well as a scratch on the outer circumferential surface of the pipe in order to prevent the wrench from slipping, the manufacturing time and cost of the pipe is increased.

Therefore, the present invention for solving the above problems, in particular, while the handle is provided with a pressure lever while pressing the first and second fixing parts coupled to the outer circumferential surface of the pipe while rotating the pipe clockwise or counterclockwise, They can be combined or detached by rotating the pipe continuously without removing a wrench on the pipe, thereby saving time and cost of work, and the fixing protrusions protruding from the first and second fixing parts rub against the outer circumferential surface of the pipe. By rotating the pipe in a clockwise or counterclockwise direction while generating an operator, the workers can combine or detach the pipe using a small force, as well as the first and second 2 Since the fixing part has a different diameter, pipes of different diameters can be joined or separated. It relates to a pipe wrench which is capable of continuous operation to.

Therefore, the present invention for achieving the above object

 Protruding the pressure lever inclined at one end of the handle, a pair of first coupling pieces are formed to extend to the flow hole on one side and the first fixing part of the semi-circular shape formed with a plurality of fixing projections protrude in the inner diameter of the handle Rivet coupling to one side end, the plurality of fixing projections formed in the annular form by riveting the second fixing part formed in the inner diameter to the one end of the first fixing part,

The second fixing part is integrally formed to extend the pressing part at one side end so that the pressing part of the second fixing part rotates the inner side of the flow hole around the rivet, and protrudes the pressing protrusion corresponding to the pressing lever on the outer circumferential surface of the pressing part. When the handle is rotated in a clockwise or counterclockwise direction, the pressing lever is characterized in that the pipe can be rotated continuously while being in close contact with or separated from the pressing projection.

According to the present invention, the handle is provided with a pressure lever continuously rotates the pipe clockwise or counterclockwise while pressing the first and second fixing parts coupled to the outer circumferential surface of the pipe, so that workers do not remove the wrench from the pipe. The pipes can be continuously rotated to be combined or separated to save time and money. The fixing projections formed on the first and second fixing parts generate friction with the outer circumferential surface of the pipe in a clockwise direction. Alternatively, by rotating in a counterclockwise direction, workers can join or separate pipes using a small force, as well as different diameters of the first and second fixing parts depending on the position where the pressing lever is in close contact with the pressing protrusion. As a result, the effect of joining or separating pipes of different diameters can be expected.

Hereinafter, with reference to the accompanying Figures 1 to 6 will be described a preferred embodiment of the present invention.

First, the present invention is a state in which the fixing means (2) in close contact with the outer peripheral surface of the pipe 61 such as gas pipes or water pipes by forming a wrench (6) consisting of a handle (1) and a fixing means (2) In the pipe 61 is to be coupled or separated while continuously rotating clockwise to counterclockwise.

As such, the fitting hole 13 is formed at one side of the handle 1 so that the pipe 61 can be continuously rotated, and the pressure lever 11 is formed at the tip of the handle 1 in which the fitting hole 13 is formed. Protrudingly formed to be inclined as shown in Figure 3 so that the inclined surface 12 is provided at the inner end of the pressing lever (11).

Rivet the fixing means (2) formed in an annular shape as shown in Figure 2 to the front end of the handle (1) protruding the pressure lever (11).

The fixing means 2 is composed of a semi-circular first fixing part 3 and a second fixing part 4.

The first fixing part 3 is a pair of first couplings provided with fitting holes 13a corresponding to the fitting holes 13 so that the flow hole 33 is formed at the rear end of the body part 3a. A piece 31 is integrally formed at the rear end of the body portion 3a, and a fitting hole 13a is provided at the distal end portion of the body portion 3a so that the second fixing portion 4 is coupled to the rivet 5a. A pair of second coupling pieces 32 are formed.

The second fixing part 4 protrudes and forms a coupling end 46 provided with a fitting hole 13a to be coupled to the inner side of the second coupling piece 32 at the front end of the body portion 4a. The pressing portion 41 protrudes integrally at the rear end of the body portion 4a so that the pressing portion 41 rotates to the left and right sides of the rivet 5 when the second fixing portion 4 is rotated about the rivet 5. Rotational movement to the left and right along the inside of the flow hole (33).

That is, the first and second fixing parts 3 and 4 having a semicircular shape are combined with rivets 5a to form an annular fixing means 2, and the pressing lever 11 is provided with the fixing means 2. Rivets (5) are coupled to the tip of the handle (1).

The pipe 61 may be rotated clockwise or counterclockwise in a state in which the first and second fixing parts 3 and 4 are in close contact with the outer circumferential surface of the pipe 61 by receiving the rotational force of the handle 1. The pressing protrusion 42 is formed to protrude on the outer circumferential surface of the pressing portion 41 to be able to.

The pressing protrusion 42 protrudes and forms a first pressing protrusion 43 having a close contact surface 45 at one end of the pressing portion 41 as shown in FIG. 4, and is spaced apart from the first pressing protrusion 43. The first and second pressure protrusions 44 having a close contact surface 45 are formed to protrude to form the first and second pressure protrusions 44 according to the position of the pressure lever 11 in close contact with the first and second pressure protrusions 43 and 44. The diameter of the two fixing parts 3 and 4 is variable.

That is, when the pressure lever 11 comes into close contact with the contact surface 45 of the first pressing protrusion 43, the first and second fixing parts 3 are formed on the outer circumferential surface of the large pipe 61 as shown in FIG. 5. 4 is in close contact with each other to rotate the pipe 61 in a clockwise or counterclockwise direction. When the pressure lever 11 comes into close contact with the contact surface 45 of the second pressing protrusion 44, the The first and second fixing parts 3 and 4 are in close contact with the outer circumferential surface of the pipe 61 having a smaller diameter to rotate the pipe 61 in a clockwise or counterclockwise direction.

In this way, a plurality of fixing protrusions 34 protrude from the inner diameters of the first and second fixing parts 3 and 4 for rotating the pipe 61 clockwise or counterclockwise by receiving the rotational force of the handle 1. The first and second fixing parts 3 and 4 are formed by the fixing protrusion 34 to increase frictional force when the first and second fixing parts 3 and 4 are in close contact with the outer circumferential surface of the pipe 61. Or rotate it counterclockwise.

As shown in FIG. 4, the fixing protrusion 34 protrudes a plurality of first fixing protrusions 35 and 35a toward the center of the inner diameters of the first and second fixing parts 3 and 4, and the A plurality of second and third fixing protrusions 36, 36a, 37 and 37a are formed to be inclined so as to face both sides of the first fixing protrusions 35 and 35a, respectively.

That is, the first fixing protrusions 35 and 35a are stuck to the outer circumferential surface of the pipe 61 to fix the first and second fixing parts 3 and 4 to the outer circumferential surface of the pipe 61.

When the handle 1 is rotated in the left direction as shown in FIG. 5A in this state, the pressing lever 11 is in close contact with the pressing protrusion 42 and the first and second fixing parts 3. The rotational force of the handle 1 is transmitted to (4), and the second fixing protrusion 36a and the third fixing protrusion 37 are embedded in the outer circumferential surface of the pipe 61 by using the transmitted rotational force. Rotate (61) clockwise.

In this state, when the handle 1 is rotated in the right direction as shown in (b) of FIG. 5, the first and second fixing protrusions 3 are formed by the frictional force between the second fixing protrusion 36 and the third fixing protrusion 37a. 4 is rotated in a state spaced apart from the outer circumferential surface of the pipe 61, so that the pipe 61 is rotated in a clockwise direction.

In this way, by continuously working by using the wrench 6 coupled to the outer circumferential surface of the pipe 61, the pipe 61 can be continuously rotated clockwise or counterclockwise.

Referring to the preferred operating state and effects of the present invention formed as described above are as follows.

First, the second fixing part 4 is rotated to the right direction as shown in FIG. 4, centering on the rivet 5a, so that the first and second fixing parts 3 are fixed to the outer circumferential surface of the pipe 61 as shown in FIG. In the state in which the (4) is combined, rotate the handle (1) to the left direction about the rivet (5).

As the handle 1 rotates in the left or right direction, the pressure lever 11 rotates the pipe 61 clockwise or counterclockwise while being in close contact with or spaced from the contact surface 45 of the pressing protrusion 42. .

That is, when the handle 1 is rotated in the left direction as shown in FIG. 5A, the pressing lever 11 is in close contact with the contact surface 45 of the pressing protrusion 42. The rotational force is transmitted to the first and second fixing parts 3 and 4 protruding from the inner diameter, and the second fixing part 36a and the third fixing part 37 are connected to the pipe 61 by using the transmitted rotating force. The pipe 61 is rotated in the clockwise direction while keeping the state embedded in the outer circumferential surface thereof.

In this way, when the pipe 61 is rotated and the force applied to the handle 1 is removed or the right handle 1 is rotated to the right direction about the rivet 5, the pressure protrusion 42 is applied. The force disappears, and the missing force causes the second fixing protrusion 36 and the third fixing protrusion 37a to rub against the outer circumferential surface of the pipe 61, and the first and second heights are centered around the rivet 5a. Only the wrench 6 is rotated counterclockwise while the government part 3, 4 is spaced apart from the outer circumferential surface of the pipe 61 so that the pipe 61 remains rotated.

That is, the pipe 61 is continuously rotated clockwise or counterclockwise by using the wrench 6.

As such, when the handle 1 is rotated around the rivet 5, the pressure lever 11 is in close contact with the pressure protrusion 42, and the rotational force of the pressure lever 11 is transmitted to the first and second fixing parts ( 3) When 4 is smeared or spaced around the rivet 5a on the outer circumferential surface of the pipe 61, the pipe 61 is continuously rotated in a clockwise or counterclockwise direction so that the workers of the pipe 61 The time for joining or separating can be reduced.

In addition, the fixing protrusion 35 protruding from the wrench 2 prevents the wrench 2 from slipping on the outer circumferential surface of the pipe 61 to the maximum, thereby maximizing the coupling and detachment of the pipe 61. Can be.

In addition, one wrench 2 is formed by differently forming diameters of the first and second fixing parts 3 and 4 according to the position where the pressing lever 11 of the wrench 2 is in close contact with the pressing protrusion 42. Using a different diameter of the pipe 61 can be rotated in a clockwise or counterclockwise direction, as well as there is no need to purchase a wrench suitable for the diameter of the pipe 61 can reduce the cost.
