Description

Technical Field

[0001] The utility model relates to the technical field related to hand tools, in particular to a pipe bender structure. Background Art

[0002] Pipe fittings are used to guide fluids to a preset location, so the pipeline configuration path is not a straight line, but needs to be detoured and bent according to the location. Therefore, in the process of pipeline configuration, pipe bender is an important matching tool. Users use pipe bender to bend pipe fittings to a preset angle and detour configuration according to environmental obstacles.

[0003] Common pipe benders in the market, such as the structure shown in Taiwan Patent Publication No. M606743, have a supporting member (31) pivotally disposed at both ends of the second member (12) in the extending direction, and cooperate with a pressing member (32) to clamp the pipe 50 to achieve the purpose of bending.

[0004] The length of the second member (12) and the distance between the supporting members (31) pivotally arranged at both ends are fixed. When the pipe 50 needs to be bent into a bending angle with a different curvature, the second member (12) and the supporting member (31) with different lengths and distances must be replaced. This causes the user to have to repeatedly replace the second member (12) and the supporting member (31) during the operation, which is very troublesome.

[0005] Although the industry has proposed a method of forming a plurality of locking holes along the extension direction of the second member (12) so that the supporting members (31) can be locked in the corresponding locking holes as required to achieve the purpose of adjusting the spacing of each supporting member (31), the user still needs to disassemble and assemble the supporting members (31) one by one, which still cannot meet the demand for speed and convenience in the piping process. Utility Model Content

[0006] In view of the above problems and deficiencies of the prior art, one object of the present invention is to provide a pipe bender structure through structural innovation to overcome the deficiencies of the prior art.

[0007] To achieve the above-mentioned purpose, the utility model proposes a pipe bender structure, including a push-up mechanism, a support arm and a plurality of support blocks. The push-up mechanism includes a handle, a set of push-up members arranged on the handle and a push-up member pivotally arranged on the handle and extending out interactively with the push-up member. The support arm is arranged corresponding to one end of the handle and has a plurality of assembly holes formed along the extension direction of the support arm and penetrating the support arm at the top and bottom. Each support block has eccentrically corresponding assembly holes pivotally arranged on the support arm, and two are arranged as a group.

[0008] Furthermore, one end of the handle is provided with an embedding groove for embedding the support arm.

[0009] Furthermore, each of the supporting blocks has a square outline.

[0010] Furthermore, each of the supporting blocks has a rectangular outline.

[0011] Furthermore, each of the support blocks has at least one pivot hole formed at the top and bottom penetrating each of the support blocks and arranged away from the center of each of the support blocks.

[0012] Furthermore, the pivot hole is concentric with the matching assembly holes, and a pivot member is provided to extend through and correspondingly screw in the matching assembly holes, so that each support block is pivotally mounted at a preset position of the support arm.

[0013] Furthermore, a group of the support blocks are arranged on the top end surface of the support arm at a preset interval.

[0014] Furthermore, another group of the support blocks is arranged on the bottom end surface of the support arm at a preset interval different from that of the top end surface of the support arm.

[0015] Beneficial effects of the utility model:

[0016] By means of the above components, the support blocks arranged on the rotating eccentric pivots can provide support distances of different sizes and positions. When the pipe is bent, the curvature of the pipe can be changed due to different support positions. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Please refer to the relevant drawings below to further illustrate the embodiment of the pipe bender structure of the utility model. The various objects in the embodiments are depicted according to the proportions, sizes, deformations or displacements suitable for the description, rather than drawn according to the proportions of the actual components, which should be explained first. And the same and symmetrically configured components in the remaining embodiments are all represented by the same numbers. In addition, the directional terms such as "front, back, left, right, up, down, inside, outside" in the description of each embodiment listed below are expressed according to the specified viewing direction and cannot be used as an interpretation of the limitation of the utility model.

[0039] See also Figures 1 to 3 As shown, the pipe bender structure of the present invention includes a push mechanism 10 , a support arm 20 , a plurality of support blocks 30 and a plurality of pivot members 40 .

[0040] The ejection mechanism 10 (prior art) comprises a handle 11, an ejection member 12 disposed on the handle 11, and a lever 13 pivotally disposed on the handle 11 and interacting with the ejection member 12. The user can operate the lever 13 to cause the ejection member 12 to extend axially along the handle 11 (the operating principle and structure belong to the prior art and will not be described in detail here).

[0041] The handle 11 (prior art) has a recessed groove 111 at one end.

[0042] The support arm 20 is arranged corresponding to the embedding groove 111 of the handle 11 and is perpendicular to the extension direction of the handle 11. It also has a plurality of assembly holes 21. Each assembly hole 21 is formed along the extension direction of the support arm 20 and penetrates the support arm 20 from top to bottom.

[0043] The above-mentioned support blocks 30 are eccentrically arranged with the assembly holes 21 corresponding to the matching ones on the support arm 20. They are arranged in a group of two and can be rotatably distributed on the top and bottom end surfaces of the support arm 20. During implementation, the support blocks 30 on the top end surface of the support arm 20 have different spacings than the support blocks 30 on the bottom end surface. And the end surfaces of the support blocks 30 are at different distances from the pivot joint due to the eccentric pivot joint.

[0044] Each of the support blocks 30 has at least one pivot hole 31 , which is formed by penetrating the support block 30 at the top and bottom and is arranged away from the center point of the support block 30 .

[0045] In addition, during implementation, the outer contour of each support block 30 is square or rectangular.

[0046] Each of the pivoting members 40 is screwed corresponding to each of the assembling holes 21 , and simultaneously extends through the pivot hole 31 of the support block 30 during the process, so that the support block 30 is pivotally mounted at a preset position of the support arm 20 .

[0047] The above is an introduction to the components and assembly method of the pipe bender structure of a preferred embodiment provided by the utility model. The actuation characteristics of the embodiment of the utility model are introduced as follows.

[0048] like Figure 4 , 5 Please also refer to Figures 1 to 3 , place the pipe fitting 50 between the ejection member 12 and each support block 30, and then operate the wrench 13 to make the ejection member 12 extend axially along the handle 11 to eject the pipe fitting 50, and both ends of the pipe fitting 50 are supported by each support block 30, so that the pipe fitting 50 is bent by the thrust of the ejection member 12, thereby achieving the purpose of bending the pipe.

[0049] In addition, if Figures 6 to 9 As shown, when the curvature of the pipe 50 needs to be changed within a small range, by rotating the different end faces of the support block 30 on the support arm 20, the different end faces of each support block 30 are at different distances from the pivot point, which will form different support size positions for the two ends of the pipe 50. In this way, the curvature of the pipe 50 bent by the thrust of the push member 12 will also be different, which is convenient for users to quickly adjust according to the needs of the on-site environment.

[0050] like Fig.10 , 11 As shown, when there is a need to change the bending curvature of the pipe 50 over a large range, the support arm 20 can be removed from the embedding groove 111 of the handle 11, and then turned over and assembled back into the handle 11. Since the support blocks 30 pivoted on the top and bottom ends of the support arm 20 have different spacings, a larger range of curvature changes can be provided.

[0051] The above description is only a preferred embodiment of the present invention, which is intended to clarify the features of the present invention, but is not intended to limit the scope of the embodiments of the present invention. Equivalent changes made by ordinary technicians in this technical field based on the present invention, as well as changes known to technicians in this field, should still fall within the scope of the present invention.
