Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin-walled pipe technology, and in particular to a device for cleaning the internal threads of thin-walled pipes. Background Technology
[0002] Thin-walled pipe fittings are pipe fittings with relatively thin walls. These fittings are used to connect, distribute, or change the flow path of a piping system. They play a key role in various piping systems, including water supply, gas supply, chemical, building, and HVAC (heating, ventilation, and air conditioning) systems. The wall thickness of thin-walled pipe fittings is usually thinner than that of the pipe body.
[0003] Currently, cleaning devices are required during the use of thin-walled pipe fittings. While existing cleaning devices can clean the fittings, they still have some shortcomings in practical use. For example, when cleaning thin-walled pipes with internal threads, it is not convenient to clean the threads on the inner wall of the fittings, which can lead to dirt residue inside the threads and affect the normal use of the thin-walled pipe fittings. Therefore, a thin-walled pipe fitting internal thread cleaning device is proposed to solve the above problems. Utility Model Content

A positive and negative threaded rod is rotatably connected to the inner wall of the U-shaped plate via two bearings. Two perforated control blocks are threadedly connected to the outer surface of the positive and negative threaded rods. A support rod is fixedly connected to the left side of each perforated control block, and a sponge strip is fixedly connected to the side of the two support rods that are far apart from each other.

[0007] Two reinforcing blocks are fixedly connected to the outer surface of the rotating rod, and the left side of each reinforcing block is fixedly connected to the right side of the U-shaped plate.
[0008] As a further description of the above technical solution:
[0009] Two reinforcing bases are fixedly connected to the left side of each mounting base, and the bottom surface of each reinforcing base is fixedly connected to the upper surface of the base.
[0010] As a further description of the above technical solution:
[0011] Each of the mounting bases has two second sliding grooves on its inner wall, and a second slider is slidably connected to the inner wall of each second sliding groove. The two sets of second sliders are fixedly connected to the front and back sides of the two clamping plates respectively on their respective sides.

[0014] As a further description of the above technical solution:
[0015] A collection box is provided above the base, and the collection box is located directly below the pipe body.
[0016] This utility model has the following beneficial effects:
[0017] 1. Compared with the prior art, this thin-walled pipe internal thread cleaning device, through the cooperation of a first sliding groove and a first sliding block, allows the carrier plate and support plate to move, thereby allowing the support rod and sponge strip to enter the interior of the pipe body. Through the cooperation of the positive and negative thread rod and the control block with holes, the sponge strip can make close contact with the thread of the pipe. By using the cooperation of the motor and the rotating rod, the U-shaped plate and support rod can be rotated, thereby allowing the sponge strip to slowly push the support plate to reset by contact with the internal thread of the pipe body, thereby cleaning the internal thread of the pipe body and effectively preventing dirt residue inside the thread.
[0018] 2. Compared with the prior art, this thin-walled pipe internal thread cleaning device, through the threaded connection between the threaded push rod and the threaded hole, enables the threaded push rod to push the clamping plate downward, thereby enabling the clamping plate to clamp the pipe body and prevent the pipe body from loosening.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1-4This utility model provides a thin-walled pipe internal thread cleaning device, comprising a base 1, two mounting seats 2 fixedly connected to the upper surface of the base 1, a clamping plate 13 slidably connected to the inner wall of each mounting seat 2, a threaded hole 12 opened on the upper surface of each mounting seat 2, a threaded push rod 11 threadedly connected to the inner wall of each threaded hole 12, a pipe body 10 commonly provided inside the two bases 1, two first sliding grooves 5 opened on the upper surface of the base 1, a first slider 16 slidably connected to the inner wall of each first sliding groove 5, a carrier plate 6 fixedly connected to the upper surface of the two first sliders 16, and the carrier plate... A support plate 8 is fixedly connected to the upper surface of 6. A motor 7 is fixedly connected to the right side of the support plate 8. A rotating rod 14 is rotatably connected to the left side of the support plate 8 via a bearing. The right end of the rotating rod 14 is fixedly connected to the output end of the motor 7. A U-shaped plate 9 is fixedly connected to the left side of the rotating rod 14. A positive and negative threaded rod 18 is rotatably connected to the inner wall of the U-shaped plate 9 via two bearings. Two perforated control blocks 19 are threadedly connected to the outer surface of the positive and negative threaded rod 18. A support rod 20 is fixedly connected to the left side of each perforated control block 19. A sponge strip 21 is fixedly connected to the side of the two support rods 20 that are far apart from each other.
[0027] In this embodiment, two reinforcing seats 3 are fixedly connected to the left side of each mounting base 2. The bottom surface of each reinforcing seat 3 is fixedly connected to the upper surface of the base 1. By providing the reinforcing seats 3, the mounting base 2 can be reinforced to prevent the mounting base 2 from becoming loose or tilted. Two reinforcing blocks 17 are fixedly connected to the outer surface of the rotating rod 14. The left side of each reinforcing block 17 is fixedly connected to the right side of the U-shaped plate 9. By providing the reinforcing blocks 17, the rotating rod 14 can be reinforced, increasing the stability of the connection between the rotating rod 14 and the U-shaped plate 9 and preventing the U-shaped plate 9 from becoming loose.
[0028] In this embodiment, a collection box 4 is provided above the base 1. The collection box 4 is located directly below the pipe body 10. The collection box 4 can collect the cleaned dirt for easy processing and to prevent the dirt from spilling. Each mounting base 2 has two second sliding grooves 15 on its inner wall. Each second sliding groove 15 has a second slider 23 slidably connected to its inner wall. The two sets of second sliders 23 are fixedly connected to the front and back sides of the two clamping plates 13 respectively on their side. The second sliders 23 and the second sliding grooves 15 can guide the clamping plates 13 to prevent them from shaking or loosening. A fixing ring 22 is fixedly connected to the outer surface of the positive and negative threaded rod 18. The fixing ring 22 is located between the two perforated control blocks 19. The fixing ring 22 can limit the two perforated control blocks 19 to prevent them from disengaging from the threaded part of the positive and negative threaded rod 18.
[0029] Working principle: During use, the pipe body 10 is placed inside the two mounting seats 2. Then, the threaded push rod 11 is rotated, so that the threaded push rod 11 is connected to the threaded hole 12, pushing the clamping plate 13 downward to clamp the pipe body 10. Then, the support plate 8 is pushed, so that the support rod 20 is inserted into the inside of the pipe body 10. Then, the positive and negative threaded rods 18 are rotated, so that the two perforated control blocks 19 drive the two sponge strips 21 to move away from each other and make close contact with the internal thread of the pipe body 10. Then, the motor 7 is started, and the motor 7 drives the rotating rod 14 to rotate, which in turn drives the U-shaped plate 9 to rotate, so that the U-shaped plate 9 drives the support rod 20 and the sponge strip 21 to rotate. Since the pipe body 10 is stationary, the sponge strip 21 and the support rod 20 can push the support plate 8 to reset through the cooperation with the internal thread of the pipe body 10. Thus, while removing the pipe body 10, the dirt is cleaned out of the pipe.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
