Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention provides a pipeline clamping tool for solving the problem in the prior art that when the space around the insertion part of the pipeline is narrow, it is difficult to assemble due to insufficient hand space.

[0031] As Figure 1 shown, the embodiment of the present invention provides a pipeline clamping tool, which includes:

[0032] A rotating part 100, including a first rotating part 110 and a second rotating part 120; wherein, the first rotating part 110 and the second rotating part 120 are hinged;

[0033] A clamping part 200, including a first clamping part 210 and a second clamping part 220;

[0034] The handle 300 includes a first handle 310 and a second handle 320;

[0035] One end of the first rotating member 110 is detachably connected to the first clamping member 210, and the other end is fixedly connected to the first handle 310; one end of the second rotating member 120 is detachably connected to the second clamping member 220, and the other end is fixedly connected to the second handle 320;

[0036] The first clamping member 210 and the second clamping member 220 enclose a receiving space for placing the pipeline. When the first handle 310 and the second handle 320 approach or move away from each other, the first clamping member 210 and the second clamping member 220 also approach or move away from each other, and the receiving space decreases or increases, clamping or releasing the pipeline.

[0037] In this embodiment, the articulated first rotating member 110 and the second rotating member 120 are both connected to the clamping member 200 and the handle 300 at both ends. The first clamping member 210 and the second clamping member 220 form the receiving space for accommodating the pipeline. When the first handle 310 and the second handle 320 are controlled by one hand to approach or move away from each other, the size of the receiving space changes, clamping or releasing the pipeline. Thus, when the working space is narrow, it can replace the hand to clamp the quick plug end of the pipeline for insertion. And during assembly, one hand operates the handle to open the tool to clamp the pipeline quick plug, and then moves the pipeline to the assembly position, and the other hand axially exerts force by pressing the side of the handle to complete the pipeline insertion.

[0038] Optionally, for the pipeline clamping tool, the first clamping member 210 includes a first clamping portion 211, and the second clamping member 220 includes a second clamping portion 221;

[0039] The first clamping portion 211 and the second clamping portion 221 are arcs with the same radius, and together enclose the receiving space. When the first clamping portion 211 and the second clamping portion 221 approach each other to fit, the centers of the first clamping portion 211 and the second clamping portion 221 coincide.

[0040] In this embodiment, in order to accommodate the pipeline with a circular cross-section, the first clamping portion 211 and the second clamping portion 221 are set as arcs with the same radius, as Figure 2 shown. When the first clamping portion 211 and the second clamping portion 221 fit, the first clamping portion 211 and the second clamping portion 221 are concentrically arranged.

[0041] Optionally, for the pipeline clamping tool described above, when the first clamping portion 211 and the second clamping portion 221 are in contact, a notch is formed on the side of the first clamping portion 211 away from the rotating member 100 and the side of the second clamping portion 221 away from the rotating member 100.

[0042] In this embodiment, as Figure 2 shown, when the first clamping portion 211 and the second clamping portion 221 are in contact, a notch is provided on the side of the clamping member 200 away from the rotating member 100, which is used to reduce the machining and fitting accuracy at this place, and at the same time reduce the opening stroke when the pipeline clamping tool clamps the pipeline.

[0043] Optionally, for the pipeline clamping tool described above, the pipeline clamping tool includes a plurality of the clamping members 200 with different radius sizes for clamping pipelines with different diameter sizes.

[0044] In this embodiment, as Figure 3 shown, the first rotating member 110 and the first clamping member 210, as well as the second rotating member 120 and the second clamping member 220, are detachably connected. By replacing the clamping members 200 with different radius sizes, pipelines with different diameter sizes can be adapted. Usually, two clamping members with the sum of their radius sizes greater than the pipeline diameter by 1 mm are used for matching, so as to avoid damaging the pipeline or the quick connector of the pipeline when the pipeline clamping tool clamps. An example of detachable connection by screwing is shown in the figure, and the detachable connection method in the present invention is not limited to this.

[0045] Optionally, for the pipeline clamping tool described above, the first clamping member 210 further includes a first connecting portion 212, and the second clamping member 220 further includes a second connecting portion 222;

[0046] wherein, the first connecting portion 212 is detachably connected to the first rotating member 110, and a first baffle 213 is provided on the side of the first connecting portion 212 facing away from the second clamping member 220 to limit the relative rotation between the first rotating member 110 and the first clamping member 210;

[0047] the second connecting portion 222 is detachably connected to the second rotating member 120, and a second baffle 223 is provided on the side of the second connecting portion 222 facing away from the first clamping member 210 to limit the relative rotation between the second rotating member 120 and the second clamping member 220.

[0048] In this embodiment, as Figure 5As shown, the first baffle 213 and the second baffle 223 are respectively provided on the first connecting portion 212 and the second connecting portion 222, so as to limit the relative rotation between the first rotating member 110 and the first clamping member 210, and between the second rotating member 120 and the second clamping member 220. Similarly, as Figure 3 and Figure 4 shown, on one side where the first rotating member 110 and the second rotating member 120 are close to the handle 300, stoppers are provided to limit the relative rotation between the first rotating member 110 and the second rotating member 120, and to prevent rotation to a state that is not convenient for use.

[0049] Optionally, for the pipeline clamping tool, when the first clamping portion 211 and the second clamping portion 221 are in contact, the first connecting portion 212 and the second connecting portion 222 are in contact.

[0050] In this embodiment, as Figure 2 shown, when the first clamping portion 211 and the second clamping portion 221 are in contact, the first connecting portion 212 and the second connecting portion 222 are in contact, so as to play a role in limiting the pipeline.

[0051] Optionally, for the pipeline clamping tool, the first rotating member 110 and the second rotating member 120 are hinged together by a rivet.

[0052] In this embodiment, as Figure 1 and Figure 2 shown, the first rotating member 110 and the second rotating member 120 are hinged together by a rivet, so as to keep the rotation between the first rotating member 110 and the second rotating member 120 smooth.

[0053] Optionally, for the pipeline clamping tool, the rotating member 100, the clamping member 200 and the handle 300 are all made of stainless steel.

[0054] In this embodiment, the rotating member 100, the clamping member 200 and the handle 300 are all made of stainless steel, so as to extend the service life of the pipeline clamping tool. And at the sharp edges of the rotating member 100, the clamping member 200 and the handle 300, rounded corners are provided. And when a welding connection method is adopted between the rotating member 100 and the handle 300, the welding points are polished smoothly to avoid scratching parts and hands.

[0055] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
