Description

Technical Field

[0001] This utility model relates to the field of water, electricity and gas installation technology, and in particular to a pipe wrench for water, electricity and gas installation based on the lever principle. Background Technology

[0002] Plumbing and electrical installation pipe wrenches are tools designed using the lever principle. They are primarily used to increase clamping force, ensure stable transmission during use, and improve operational stability. These pipe wrenches, through the lever principle, allow users to clamp and manipulate pipe fittings with less effort. Specifically, the design includes a first handle and a second handle, which form a lever system through the interaction of an arc-shaped rod and a straight rod. The front end of the first handle has a jaw seat, and the front end of the jaw seat has a first concave arc-shaped jaw. The front end of the second handle is an "L"-shaped rod, the corner of which is rotatably connected to the rear of the jaw seat. This design allows users to amplify force through leverage when applying force, thus making it easier to clamp pipe fittings.

[0003] However, existing water, gas, and electricity installation pipe wrenches can only clamp water, gas, and electricity pipes of a single diameter, which reduces the flexibility of the wrenches. Furthermore, a large amount of force is required to clamp the water, gas, and electricity pipes, which puts them under great pressure, causing them to deform and be damaged. Therefore, improvements are needed. Utility Model Content

[0056] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a pipe wrench for water, electricity and gas installation based on the lever principle.

[0057] A pipe wrench for water, electricity, and gas installation based on the lever principle includes a support shaft 1 and a fixing plate 2, with the fixing plate 2 fixedly connected to the support shaft 1; it also includes: a support plate 3, disposed on the support shaft 1 and rotatably connected to the support shaft 1; a support block 4, disposed on the support plate 3 and fixedly connected to the support plate 3; a fixing block 5, disposed on the support block 4 and fixedly connected to the support block 4; multiple clamping blocks 6, evenly disposed on the fixing block 5 and fixedly connected to the fixing block 5; a telescopic mechanism, disposed on the support plate 3, for clamping water, electricity, and gas pipes of different diameters; and a clamping mechanism, disposed on the fixing plate 2, for clamping the fixing clamping blocks 6.

[0058] Reference Figure 5 In a preferred embodiment, the telescopic mechanism includes: a telescopic frame 7, which is disposed on the support plate 3 and fixedly connected to the support plate 3; a motor frame 8, which is disposed on the telescopic frame 7 and fixedly connected to the telescopic frame 7; a telescopic motor 9, which is fixedly connected to the motor frame 8; a telescopic shaft 10, which is detachably fixedly connected to the output end of the telescopic motor 9; and a rotating component, which is disposed on the telescopic shaft 10.

[0059] This configuration ensures that when the telescopic motor 9 is running, it drives the telescopic shaft 10, which is detachably and fixedly connected to the output end of the telescopic motor 9, to rotate, thus providing power for the operation of the rotating components.

[0060] Reference Figure 5 In a preferred embodiment, the rotating component includes: a rotating disk 11, which is disposed on the telescopic shaft 10 and fixedly connected to the telescopic shaft 10; a rotating block 12, which is disposed in the telescopic frame 7 and fixedly connected to the telescopic frame 7; a rotating groove 13, which is formed on the rotating disk 11; a telescopic groove 14, which is formed on the rotating block 12; and a sliding component, which is disposed in the telescopic groove 14.

[0061] This configuration allows the rotating disk 11, which is fixedly connected to the telescopic shaft 10, to rotate, thereby driving the sliding components to operate.

[0062] Reference Figure 5In a preferred embodiment, the sliding assembly includes: a sliding block 15 disposed in the telescopic groove 14 and slidably connected to the telescopic groove 14; a sliding shaft 16 fixedly connected to the sliding block 15 and slidably connected to the rotating groove 13; and an arc-shaped plate 17 disposed on the sliding block 15 and fixedly connected to the sliding block 15.

[0063] This configuration allows the sliding shaft 16 to slide within the rotating groove 13, and the sliding block 15, which is fixedly connected to the sliding shaft 16, to slide within the telescopic groove 14. This causes the arc-shaped plate 17, which is fixedly connected to the sliding block 15, to move, thereby enabling the clamping of water, electricity, and gas pipes of different diameters.

[0064] Reference Figure 4 In a preferred embodiment, the clamping mechanism includes: a fixed frame 18, which is disposed on the fixed plate 2 and fixedly connected to the fixed plate 2; a clamping cylinder 19, which is disposed inside the fixed frame 18 and fixedly connected to the fixed frame 18; a clamping rod 20, which is slidably connected to the clamping cylinder 19; a clamping rack 21, which is fixedly connected to the clamping rod 20; and a rotating component disposed on the fixed frame 18.

[0065] This configuration allows the clamping cylinder 19 to slide when it is in operation, causing the clamping rod 20, which is slidably connected to the clamping cylinder 19, to slide. This, in turn, causes the clamping rack 21, which is fixedly connected to the clamping rod 20, to move, providing power for the operation of the rotating components.

[0066] Reference Figure 4 In a preferred embodiment, the rotating component includes: a plurality of rotating shafts 22, which are evenly arranged on the fixed frame 18 and fixedly connected to the fixed frame 18; a rotating gear 23, which is arranged on the rotating shafts 22, rotatably connected to the rotating shafts 22, and meshes with the clamping rack 21; a rotating rod 24, which is fixedly connected to the rotating gear 23; and a rotating groove 25, which is formed on the rotating rod 24.

[0067] This configuration allows the rotating gear 23, which meshes with the clamping rack 21, to rotate around the axis of the rotating shaft 22, thereby causing the rotating rod 24, which is fixedly connected to the rotating gear 23, to rotate, thus achieving the clamping and fixing of the support plate 3.

[0068] Working principle: When working, the telescopic motor 9 is started first, which drives the telescopic shaft 10, which is detachably and fixedly connected to the output end of the telescopic motor 9, to rotate. This causes the rotating disk 11, which is fixedly connected to the telescopic shaft 10, to rotate, thereby driving the sliding shaft 16 to slide in the rotating groove 13. This causes the sliding block 15, which is fixedly connected to the sliding shaft 16, to slide in the telescopic groove 14, thereby causing the arc plate 17, which is fixedly connected to the sliding block 15, to move.

[0069] Next, the clamping cylinder 19 is activated, which drives the clamping rod 20, which is slidably connected to the clamping cylinder 19, to slide, causing the clamping rack 21, which is fixedly connected to the clamping rod 20, to move. This causes the rotating gear 23, which meshes with the clamping rack 21, to rotate around the axis of the rotating shaft 22, thereby causing the rotating rod 24, which is fixedly connected to the rotating gear 23, to rotate.

[0070] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
