Description

[Technical Field]

[0001] The present invention relates to a pipe cutter structure, and in particular to a pipe cutter structure in which a slide unit of the pipe cutter structure is displaced within a first housing tank, the main unit and the slide unit are pivotally attached to a screw shaft unit, the slide unit is housed in a pressing unit, and the main unit, slide unit, screw shaft unit, and pressing unit can be reliably assembled. [Background technology]

[0002] Prior art pipe cutter structures (for example, Patent Documents 1 and 2) utilize the principle of a seesaw structure, and Figure 1 of Patent Document 1 shows member 8. When the seesaw (i.e., member 8) is pressed, the screw portion and the screw shaft separate, allowing the pushing member 2 to be quickly displaced. Figure 1 of Patent Document 2 shows member 21. When the seesaw (i.e., member 21) is pressed, the screw portion and the screw shaft separate, allowing the pushing member 2 to be displaced.

[0003] The pipe cutter structure 1 of Patent Documents 2 and 3 has an adjustment member 5 and a support member 4 assembled on a C-shaped work head 3.

[0004] The conventional pipe cutter structure has the following drawbacks (1) and (2). (1) As shown in the cross-sectional view of Figure 6, the cutting member 10 and the spindle portion 15 are not positioned on the same axis. After the cutting member 10 receives a force, the force is transmitted to the engaging member 21. The engaging member 21 and the spindle portion 15 form an interlocking structure. The teeth of the engaging member 21 receive a large torque. This type of positioning structure, which is arranged alternately, takes up a large amount of structural space and is prone to becoming unstable when subjected to force. (2) The engagement between the toothed section 26 of the engaging member 21 and the receiving member 19 is released, and the cutting member 10 and the engaging member 21 slide within the groove-shaped guide device 9, but the engaging member 21 uses a seesaw principle similar to the principle of a lever to control the engagement between the toothed section 26 and the receiving member 19. In other words, the position of the axis u of the engaging member 21 is very important, and if there is an error in the position of the axis u, the meshing relationship of the control structure between the engaging member 21 and the receiving member 19 is likely to shift position, making the meshing unstable.

The control member 52 restricts the pressing member 51, assembling the control unit 50 onto the slide unit 30 and preventing it from coming off. The third connecting member 54 is assembled to the pressing member 51 and the control member 52. The third connecting member 54 is restricted by the slotted groove 315. The control unit 50 is assembled onto the slide unit 30 and prevents it from coming off. The control unit 50 is restricted on the screw shaft unit 40 and the slide unit 30. The control unit 50 has two restricting structures to prevent it from coming off.

[0040] When the control unit 50 is pressed, the pressing member 51 and the control member 52 are displaced within the sixth storage tank 313. When the elastic member 53 is compressed, the second threaded portion 521 and the first threaded portion 422 are disengaged, and when the control unit 50 is pressed to displace the slide unit 30, the distance from the cutter wheel 32 to the gear unit 20 is adjusted, and when the pressure on the control unit 50 is released, the elastic tension of the elastic member 53 is restored, and the second threaded portion 521 and the first threaded portion 422 are engaged and positioned.

[0041] Please refer to Figures 11 to 13. Figure 11 is an assembled perspective view showing a pipe cutter structure according to an embodiment of the present invention. Figure 12 is a side view showing a pipe cutter structure according to an embodiment of the present invention. Figure 13 is a cross-sectional view taken along line AA in Figure 12. As shown in Figures 11 to 13, the gear unit 20 is assembled to the second housing tank 114. The slide unit 30 is housed in the first housing tank 111. The slide unit 30 is linearly displaceable within the first housing tank 111. The screw shaft 42 is pivotally mounted within the first pivot mounting portion 113 and the fifth housing tank 312. The second pivot mounting portion 421 is pivotally mounted to the first pivot mounting portion 113. The screw shaft unit 40 is pivotally mounted on the main unit 10 and the slide unit 30 and is rotatable. The control unit 50 is housed in the sixth housing tank 313 and is displaceable within the sixth housing tank 313.

[0042] Please refer to FIG. 14. FIG. 14 is a cross-sectional view taken along line AA in FIG. 12 when the rotating member 41 is in the first operating state. As shown in FIG. 14, when the rotating member 41 is rotated, the second pivot portion 421 is restricted by the two abutment edges 1131, so the screw shaft 42 can only rotate on its axis. The second screw portion 521 is pressed by the elastic force of the elastic member 53 and engages with the first screw portion 422. The control unit 50 is displaced linearly as the first screw portion 422 rotates. The control unit 50 drives the slide unit 30 to displace it linearly within the first storage tank 111, allowing the user to adjust the distance from the cutter wheel 32 to the gear unit 20 as desired.

[0043] Please refer to Figures 15 and 16. Figure 15 is a cross-sectional view taken along line AA in Figure 12 when the control unit 50 is in the second operating state. Figure 16 is a cross-sectional view taken along line AA in Figure 12 when the control unit 50 is in the third operating state. As shown in Figures 15 and 16, when the control unit 50 is pressed, the elastic member 53 is compressed, and the second screw-threaded portion 521 and the first screw-threaded portion 422 are disengaged. When the operator continues to press the control unit 50, the slide unit 30 is displaced, adjusting the distance from the cutter wheel 32 to the gear unit 20. When the pressure on the control unit 50 is released, the elastic member 53 uses its recovery elastic tension to engage the second screw-threaded portion 521 and the first screw-threaded portion 422, thereby positioning them.

[0044] In another embodiment of the present invention, a cushion may be attached to the first surface 1111 or the sliding seat 31 corresponding to the first surface 1111, and the cushion may absorb the impact force generated when the sliding seat 31 is displaced.

[0045] As can be seen from the above, the pipe cutter structure according to the present invention has the following advantages (1) to (11). (1) The slide unit 30 is provided, and the slide unit 30 is displaceable within the first housing tank 111. A screw shaft unit 40 is pivotally attached to the main body unit 10 and the slide unit 30. A control unit 50 is housed in the slide unit 30. This allows the main body unit 10, slide unit 30, screw shaft unit 40, and control unit 50 to be reliably assembled. (2) By displacing the control unit 50 linearly, it is possible to control the engagement and disengagement of the second threaded portion 521 and the first threaded portion 422. The position of the sixth housing tank 313 may have a large tolerance. After the control unit 50 is housed in the sixth housing tank 313, the second threaded portion 521 can be engaged with the first threaded portion 422 simply by slightly rotating the screw shaft unit 40, and the engagement relationship can be reliably controlled by displacing the control unit 50 linearly. (3) Since the control unit 50 can be linearly displaced to control the engagement and disengagement of the second threaded portion 521 and the first threaded portion 422, the width of the sixth container 313 can be increased for a larger pipe cutter structure. The control member 52 may have a larger width. This allows the second threaded portion 521 to have more teeth and engage with the first threaded portion 422, thereby increasing or changing the width of the sixth container 313 and the control member 52. In other words, a reliable structure can be designed by increasing or decreasing the number of engaging teeth. (4) The first shaft 3112 and the second shaft 3121 intersect perpendicularly at one point. The axis of the screw shaft unit 40 overlaps with the second shaft 3121. That is, the cutter wheel 32 and the first shaft 3112 are arranged perpendicular to the axis of the screw shaft unit 40. This allows the screw shaft unit 40 and the slide unit 30 to be firmly assembled. (5) When a force is applied to the cutter wheel 32, the force of the cutter wheel 32 is directly received by the slide unit 30. The slide unit 30 has a large area and is assembled with the main body unit 10 and the screw shaft unit 40, so that it can receive a larger torque force. (6) The main body unit 10 and the slide unit 30 are assembled, and the slide unit 30 and the screw shaft unit 40 are in a pivotal relationship. The screw shaft unit 40 and the main body unit 10 are in a pivotal relationship. Two of the three components, the main body unit 10, the slide unit 30, and the screw shaft unit 40, are in a combined relationship. The combined relationship between these three components has high structural stability and a simple combination method. (7) The threaded shaft unit 40 restricts the control unit 50. The control unit 50 is restricted by the slotted groove 315. That is, the control unit 50 is restricted on the threaded shaft unit 40 and the slide unit 30. The control unit 50 has two restricting structures to prevent it from coming off. Two of the slide unit 30, the threaded shaft unit 40, and the control unit 50 are in a combination relationship, which makes the combination relationship between the three more reliable. (8) When the screw shaft unit 40 is rotated, the control unit 50 is driven to displace the slide unit 30 to adjust the distance from the cutter wheel 32 to the gear unit 20, or the control unit 50 is pressed to disengage the second threaded portion 521 from the first threaded portion 422, and the pressure is continued to push the control unit 50. The control unit 50 can displace the slide unit 30 to adjust the distance from the cutter wheel 32 to the gear unit 20. The pipe cutter structure of the present invention has two different control structure methods to adjust the distance from the cutter wheel 32 to the gear unit 20. (9) The fifth storage tank 312 has a first arcuate surface 3122 and a plurality of second arcuate surfaces 3123. The first arcuate surface 3122 and the plurality of second arcuate surfaces 3123 are pivotally attached to the first screw-type portion 422. This prevents the screw shaft 42 from shifting position. The screw shaft 42 generally has a predetermined length. When the second pivot-type portion 421 at one end of the screw shaft 42 is pivotally attached to the first pivot-type portion 113, the first screw-type portion 422 is pivotally attached to the first arcuate surface 3122 and the plurality of second arcuate surfaces 3123, thereby providing the screw shaft 42 with a suitable pivot structure. (10) The slide unit 30 is first combined with the screw shaft unit 40 and the control unit 50. The combination of the slide unit 30, screw shaft unit 40, and control unit 50 is easier, and after the three are combined, they can be installed on the main unit 10. (11) The slide unit 30 is restricted by the screw shaft unit 40 to prevent it from coming off the first storage tank 111, and a first slide guide 112 and a second slide guide 316 are provided to prevent the slide unit 30 from coming off the first storage tank 111.
