[0024] Please refer to Figures 1-4, An embodiment provided by the present utility model: A clamp for repairing tap water pipelines, including a clamp main body 1. The clamp main body 1 can be used as the main support structure of the entire clamp. An inner activity groove 2 is opened inside the clamp main body 1. An inner partition 3 is fixedly installed in the middle part of the inner activity groove 2. Bearing seats 4 are fixedly installed on both inner side walls of the inner activity groove 2. A threaded lead screw 5 is rotatably connected between the two bearing seats 4. The threaded lead screw 5 penetrates through the inner partition 3 and there is no contact between the two;

[0025] Among them, the threaded lead screw 5 is a positive and negative threaded rod. Threaded posts 6 are sleeved on both the positive and negative threads of the threaded lead screw 5. Both of the two threaded posts 6 are threadedly connected to the threaded lead screw 5. The tops of the two threaded posts 6 are fixedly installed with arc-shaped clamping members 7. The threaded posts 6 and the arc-shaped clamping members 7 are of an integrally formed structure design. The two arc-shaped clamping members 7 are arranged in mirror symmetry;

[0026] With this kind of structure design, when the threaded lead screw 5 rotates, due to the transmission characteristics of the positive and negative threads, the two threaded posts 6 threadedly connected to it will move relative to each other, that is, move closer to each other or move away from each other. Thus, the relative movement of the two threaded posts 6 drives the two arc-shaped clamping members 7 to move, so that the distance dimension between the two arc-shaped clamping members 7 can be adjusted. When the two arc-shaped clamping members 7 move away from each other, the distance increases. At this time, it can be used for clamping large-diameter tap water pipelines. When the two arc-shaped clamping members 7 move closer to each other, the distance dimension between them becomes smaller. At this time, it can be used for repairing and clamping small-diameter tap water pipelines;

[0027] The present utility model can dynamically adjust the applicable dimension distance between the two pipeline clamping members through the positive and negative thread transmission method, so that the present utility model can be used for repairing and clamping tap water pipelines with different diameters. The structure adjustment is highly flexible and convenient to adjust, effectively improving the size coverage range of the present utility model, having a good use effect, and the overall structure is simple, and the manufacturing and maintenance costs are low, which is suitable for popularization and use.

[0028] In this embodiment, in order to improve the contact effect between the arc-shaped clamping member 7 and the outer wall of the pipeline, provide a certain contact protection type to avoid clamping damage. Protective silicone strips 8 are adhered to the inner walls of the two arc-shaped clamping members 7 through glue. Thus, the provided protective silicone strips 8 can play a good role in protecting the pipeline during clamping.

[0029] In this embodiment, in order to improve the linear displacement guiding property between the two threaded posts 6, transverse linear guiding grooves 9 are opened on both inner end walls of the inner activity groove 2. Displacement guiding rods 10 are fixedly installed on both outer sides of the outer surfaces of the two threaded posts 6;

[0030] Furthermore, the top ends of the displacement guiding rods 10 are placed in the linear guiding grooves 9, and the displacement guiding rods 10 are slidably connected to the linear guiding grooves 9;

[0031] With this structural design, the utility model is provided with a displacement guide rod 10 and a linear guide groove 9. With this structural design, when the two threaded columns 6 perform relative linear movement, the displacement guide rod 10 can move synchronously within the linear guide groove 9, so that the movement of the stud column 6 has a certain limiting and guiding effect, avoiding the rotation of the threaded column 6 following the thread, ensuring the normal displacement transmission characteristics, and having a certain displacement guiding property at the same time, improving the overall use effect.

[0032] In this embodiment, in order to facilitate the manual adjustment work of the threaded lead screw 5, one end of the threaded lead screw 5 passes through the side wall of the fixture main body 1 and is fixedly connected to a rod knob 11. The rod knob 11 is provided with anti-slip serrations, so that the rod knob 11 can be manually rotated to drive the threaded lead screw 5 to rotate;

[0033] In this embodiment, in order to facilitate the connection between the fixture and the ground, both sides of the lower surface of the bottom end of the fixture main body 1 are fixedly installed with mounting seats 12, and the mounting seats 12 are designed in an "L" shape;

[0034] Among them, the mounting seat 12 is provided with a mounting hole 13, and an obliquely arranged reinforcing rib 14 is installed on the side wall of the mounting seat 12. The other end of the reinforcing rib 14 is fixedly connected to the lower surface of the fixture main body 1;

[0035] The pipeline after being clamped can be fixed on the ground through the provided mounting seat 12, so as to complete the overall fixed use effect. And the overall structural strength of the mounting seat 12 can be effectively improved through the obliquely arranged reinforcing rib 14, making it have better compressive resistance, effectively avoiding the deformation of the bottom structure, and ensuring the use effect.

[0036] Working principle: When the utility model is specifically used, two arc-shaped clamping members 7 can be sleeved outside the tap water pipeline to be overhauled. At this time, the rod knob 11 can be manually rotated to drive the threaded lead screw 5 to rotate;

[0037] When the threaded lead screw 5 rotates, due to the transmission characteristics of the positive and reverse threads, the two threaded columns 6 threadedly connected thereto will move relative to each other, that is, approach or move away from each other (this effect depends on the forward and reverse rotation of the rod knob 11), so as to drive the two arc-shaped clamping members 7 to move through the relative movement of the two threaded columns 6, so that the distance dimension between the two arc-shaped clamping members 7 can be adjusted;

[0038] When the two arc-shaped clamping members 7 move away from each other, the distance between the arc-shaped clamping members 7 increases. At this time, it can be used for clamping and overhauling large-diameter tap water pipelines;

[0039] When the two arc-shaped clamping members 7 approach each other, the spacing dimension between them becomes smaller. At this time, it can be used for repairing and clamping small-diameter tap water pipes.

[0040] According to the above description, when the two arc-shaped clamping members 7 approach each other, the tap water pipe between them can be surrounded and clamped, so as to ensure the normal use of this fixture. At this time, the overall fixture can be installed on the ground through the installed mounting seat 12. Thus, through the fixture of the present utility model, the overall clamping and supporting work can be completed during the repair of the tap water pipe.

[0041] The present utility model can dynamically adjust the applicable dimension spacing of the two pipe clamping members through the way of positive and reverse screw transmission, so that the present utility model can be used for repairing and clamping tap water pipes with different diameters. The structure adjustment is highly flexible and convenient, effectively improving the dimension coverage range of the present utility model and having a good use effect.

[0042] Moreover, the present utility model is provided with a displacement guide rod 10 and a linear guide groove 9. With this structural design, when the two threaded columns 6 perform relative linear movement, the displacement guide rod 10 can move synchronously in the linear guide groove 9, so that the movement of the stud column 6 has a certain limiting and guiding effect, avoiding the rotation of the threaded column 6 following the thread, ensuring the normal displacement transmission characteristics, and at the same time having a certain displacement guiding property during the movement, improving the overall use effect. Moreover, the overall structure of the present utility model is simple, the manufacturing and maintenance costs are low, and the applicable dimensions of the fixture can be adjusted flexibly extremely conveniently. The applicable pipe size range is wide and the limitation is low, which is suitable for popularization and use.

[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
