[0033] Specifically, to solve the problems in the prior art that manually cutting the pipe 14 is laborious and the cutting efficiency is not high, and electric cutting is limited by the power supply capacity and is restricted in use in the field area; the pipe cutting device provided by the utility model drives the driving wheel 4 to rotate through the driving mechanism, the driving mechanism can be electric or manual, the rotation of the driving wheel 4 drives the connecting component 6 eccentrically connected to the driving wheel 4 to move, under the combined action of the guiding function of the guiding component 7 and the movement of the connecting component 6, the cutting component 9 makes a reciprocating motion to complete the push-pull sawing action, and at the same time the pipe 14 is clamped by the clamping component 12, and under the action of the reciprocating motion of the cutting component 9, the pipe 14 is cut by the cutting component 9, which not only saves time and effort when cutting the pipe 14, but also can cut the pipe 14 in a manual driving mode when the power supply is inconvenient, and has strong applicability.

[0034] In this embodiment, the driving mechanism is manually driven. The manually driven driving mechanism can cut the pipe 14 in a manual driving mode when the power supply is inconvenient, improving the applicability of the pipe cutting device.

[0035] Optionally, the base includes a seat plate 27 and at least two support pipes 13 arranged on the lower side of the seat plate 27, and an avoidance groove is arranged on the upper side of the seat plate 27 at a position corresponding to the cutting component 9.

[0036] Specifically, the seat plate 27 can adopt a flat plate structure, and it can be stably supported by two support pipes 13 on its lower side. The support pipes 13 can adopt square pipes and are welded to the seat plate 27; the setting of the avoidance groove is used to avoid the cutting component 9, preventing the cutting component 9 from contacting or colliding with the seat plate 27 and causing damage when the cutting component 9 cuts the pipe 14 to the final stage.

[0037] In this embodiment, the avoidance groove is used to avoid the cutting tool of the cutting member 9, and the avoidance groove is a V-shaped groove.

[0038] Optionally, the driving wheel 4 is arranged on one side of the frame 2, and a box body is formed on the other side of the frame 2. The box body is connected with a box door 18 through a hinge 21.

[0039] Specifically, the frame 2 is provided with a box body on the other side of the driving wheel 4 to form a storage space, which is convenient for placing tools, articles, etc.

[0040] In this embodiment, as Figure 4 shown, the frame 2 includes a plate-shaped frame 2 body. The frame 2 body serves as one side wall of the box body. The other side wall of the box body is a side plate 20 spaced apart from the frame 2 body on the side away from the driving wheel 4. The side plate 20 is connected to the upper end of the frame 2 body by a top plate 16. A partition 17 is arranged inside the box body. A support frame 19 is arranged below the partition 17. Two bearing seats are arranged on the support frame 19. The two bearing seats are respectively connected to a second bearing 22 and a third bearing 23.

A clamping plate 24 is movably arranged in the clamping space. The two ends of the clamping plate 24 are respectively in sliding fit with the two guide plates 26. And the two ends of the clamping plate 24 are connected to the base through elastic members 25. The elastic members 25 can apply an elastic force to the clamping plate 24 to move downward towards the base.

[0042] Specifically, as Figure 5 shown, under the action of the elastic members 25, the clamping plate 24 clamps the pipe 14 inserted into the clamping space downward, realizing automatic clamping of the pipe 14. After clamping, there is no need to hold it, making the cutting operation convenient.

[0043] Optionally, the cutting member 9 includes a bracket 30, and a cutting tool is connected to the lower end of the bracket 30.

[0044] Specifically, as Figure 6 shown, the bracket 30 can adopt an inverted U-shaped structure, and the two ends are respectively connected to the two ends of the cutting tool.

[0045] In this embodiment, slots are opened at both ends of the bracket 30, and part of the cutting tool is embedded in the slots and fixed by bolt assemblies, which is convenient for replacement and maintenance.

[0046] Optionally, the driving wheel 4 is a gear, and the driving mechanism includes a gear shaft 3 meshing with the driving wheel 4. The gear shaft 3 is rotatably connected to the frame 2, and a hand wheel 1 is arranged at one end of the gear shaft 3.

[0047] Specifically, the handwheel 1 is the operating end of a manually driven driving mechanism. By rotating the handwheel 1, the gear shaft 3 can be driven to rotate. Through the meshing of the gear shaft 3 and the driving wheel 4, the driving wheel 4 can be driven to rotate. Then, driven by the driving wheel 4, the connecting component 6 is used to pull the cutting component 9 to move. During this process, due to the guiding action of the guiding component 7, the cutting component 9 can reciprocate to complete the push-pull sawing action, so as to cut the pipe 14 clamped below the cutting component 9.

[0048] Optionally, the guiding component 7 is rod-shaped. A rotating connecting column 15 is arranged on the upper part of the frame 2. One end of the guiding component 7 is rotatably connected to the rotating connecting column 15. The guiding component 7 is provided with a guiding groove. A sliding connecting column 28 is arranged on the upper part of the cutting component 9. The upper end of the sliding connecting column 28 is slidably matched with the guiding groove through a pin 29.

[0049] Specifically, the guiding groove extends along the axial direction of the guiding component 7. An upward-extending sliding connecting column 28 is arranged on the upper part of the cutting component 9. A pin 29 is arranged at the upper end of the sliding connecting column 28. The pin 29 is slidably arranged in the guiding groove. Through the cooperation of the guiding groove and the pin 29, a guiding effect can be formed on the movement of the cutting component 9.

[0050] In this embodiment, the guiding component 7 is connected to the upper end of the rotating connecting column 15 through a first bearing 8.

[0051] Furthermore, in order to ensure that the cutting component 9 can cut off the pipe 14 while also restricting the lowest position of the cutting component 9, a limiting block can also be arranged on the frame 2. Through the limiting cooperation between the limiting block and the guiding component 7, the cutting component 9 has a lowest cutting position. The lowest cutting position cooperates with the avoidance groove to better avoid the cutting tool of the cutting component 9 hitting the seat plate 27.

[0052] Optionally, the connecting component 6 is rod-shaped. A hinge seat 31 is arranged on the side of the cutting component 9. One end of the connecting component 6 is hinged to the hinge seat 31.

[0053] Specifically, the hinge seat 31 extends from the side wall of the cutting component 9 close to the frame 2 towards the direction close to the frame 2. The connecting component 6 is rotatably connected to the hinge seat 31. The movement of the connecting component 6 drives the cutting component 9 to move.

[0054] Optionally, a counterweight 10 is arranged at the other end of the guiding component 7.

[0055] Specifically, the setting of the counterweight 10 can increase the weight at the other end of the guiding component 7, so that the cutting component 9 has a greater pressure pressing towards the pipe 14, improving the cutting effect; at the same time, as Figure 1As shown, the inclined state of the guiding groove enables the connecting component 6 to be pulled back under the action of the driving wheel 4, and the guiding effect of the guiding component 7 results in less wear when the cutting tool is retracted.

[0056] In this embodiment, a stud is provided at the other end of the guiding component 7, and the counterweight 10 is provided with a through hole for the stud to pass through. The fixation of the counterweight 10 can be achieved through the cooperation of the nut 11 and the stud.

[0057] Optionally, the cutting tool includes a saw blade 32 and / or a blade.

[0058] Specifically, the cutting tool can be selected according to the material of the pipe 14. When cutting a pipe 14 with a relatively hard material, a saw blade 32 can be used; when cutting a pipe 14 with a relatively soft material, a blade can be used, as long as the pipe 14 can be cut smoothly. Additionally, multiple saw blades 32 and multiple blades can also be prepared in advance for selection and replacement during use.

[0059] In this embodiment, the cutting tool is a saw blade 32.

[0060] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
