Description

Pipe cutter structure

The invention relates to all the tube structures, in particular to a control unit of the pipe cutter structure, which is arranged at the side of the screw, so that the second screwing portion of the control member has a first length, and the length direction of the first length It is parallel with the axis of the screw, so that the second screwing portion has a large meshing distance with the screw, and the screw has a large supporting force.

As is known in the prior art, the conventional pipe cutter structure, such as the U.S. Patent No. 3,145,469, is based on a body 1 which is in the form of a C-shaped body, and the body 1 is pivotally provided with a plurality of ends. The first body 2 is provided with an accommodating space 4, and the accommodating space 4 is provided with a first pivot portion 11; a moving rod 5, which is a rod-shaped external thread The moving rod 5 is pivotally disposed at the first pivot portion 11 , and the moving rod 5 is rotatable and displaceable at the first pivot portion 11 . The moving rod 5 is provided with a rotating portion 6 at one end for the user. Rotating, the moving rod 5 is provided with a top portion 7 at the other end; a moving seat 8 is pivotally disposed on the body 1 and abuts against the top portion 7, and the moving seat 8 is provided with a second knife The body 10 has a second body 10 that is opposite to the first body 2, and the second body 10 has a circular shape. When the moving rod 5 is rotated and displaced at the first pivot portion 11, The movable seat 8 can be moved to adjust the distance between the second body 10 and the first body 2; a pressing member 14 is pivoted to the body 1 by the second pivot 15 The engaging member 18 is provided with an engaging portion 18 at one end thereof, and the engaging portion 18 is engaged with the external thread of the moving rod 5; an elastic member 17 elastically abuts against the body 1 and the pressing member 14 The user can press the pressing member 14 to compress the elastic member 17 by the pressing member 14. The engaging portion 18 is disengaged from the moving rod 5, and the moving rod 5 can be The first pivot portion 11 is linearly displaced.

However, the missing structure of this conventional pipe cutter is:

1. As shown in the first figure of the bulletin, the axis of the second pivot rod 15 is perpendicular to the axis of the moving rod 5, so that the pressing member 14 can only be provided with a meshing portion at one end. 18, the engaging portion 18 is engaged with the external thread of the moving rod 5, such that the pressing member 14 is at least one half of the length, and the engaging portion 18 is engaged with the moving rod 5, and the length of the engaging portion is Shorter, the support of the moving rod 5 is insufficient.

2. When the moving rod 5 is rotated and displaced at the first pivot portion 11, the arc displacement of the moving seat 8 can be driven to adjust the distance between the second body 10 and the first body 2, but The distance that the movable seat 8 can be displaced by the arc displacement is small and limited, and the adjustment space is small and inconvenient to use.

3. The moving seat 8 is in the form of an arc displacement, and the relative position difference between the second body 10 and the first body 2 is different when the second body 10 and the first body 2 are There is a loss when cutting the tube.

In view of the above-mentioned lack of the conventional pipe cutter structure, the inventors have been engaged in the manufacturing and design experience of related industries for many years, and finally have a product that can solve the drawbacks of the pipe cutter structure.

The pressing member of the conventional pipe cutter structure is only one of the lengths of the length, and the engaging portion is engaged with the moving rod, and the length of the meshing between the two is short. The control member of the pipe cutter structure of the present invention is set on the screw. a second screwing portion of the control member having a first length, the length of the first length being parallel to the axis of the screw, such that the second screwing portion of the control member and the screw With a large meshing distance, the screw has a large supporting force.

A pipe cutter structure includes: a system having a first pivot portion, a receiving groove and a first sliding rail; all the wheel trains are pivotally disposed on the body; and a sliding assembly system includes: a sliding seat, two a pivoting rod and a second roller; the sliding seat is provided with a second sliding rail, the second sliding rail is slidably disposed with the first sliding rail; the pivoting rod is pivotally disposed on the sliding seat; the roller system is The first screw portion is pivotally disposed in the first pivot portion; the rotating member is pivotally disposed on the pivot rod; the screw assembly includes: a screw and a rotating member; the first screw portion is pivotally disposed in the first pivot portion; The control unit is coupled to the control unit and the pressing member; the control unit is disposed at the receiving slot, and the control member is provided with a second screwing portion to be coupled to the first screwing portion. Engagement; the pressing member is coupled to the control member; an elastic member is received in the receiving groove, the elastic member is elastically biased on the receiving groove and the control member, so that the second screwing portion is Engaging with the first screwing portion, pressing the pressing member to drive the control member to linearly displace and press against the elastic member, and the second screwing portion is screwed with the first screwing portion Off phase open.

The control member is disposed at a side of the screw such that the control member and the second screw portion each have a first length, and the length of the first length is parallel to the axis of the screw, such that the second The screwing portion has a large meshing distance with the first screwing portion, and the meshing distance is the first length, that is, the length of the control member, and the screw has a large supporting force. The slip group of the pipe cutter structure adjusts the distance between the two rollers and the cutter wheel by linear displacement, and the space of the linear displacement of the slip group can be moved and adjusted.

Referring to the tenth and eleventh figures, when the user presses the pressing member of the control group, the pressing member is displaced inwardly and simultaneously drives the control member to also be displaced inward. The control member is Pressing the elastic member to compress the elastic member, the second screwing portion is disengaged from the first screwing portion, and the user can quickly make the screw group at the first pivot portion Displace left and right to quickly adjust the distance between the roller of the slip group and the cutter wheel.
