Description

Technical Field

[0001] This utility model relates to the field of pipe cleaning equipment technology, and in particular to a pipe inner wall cleaning brush. Background Technology

[0002] The purpose of internal pipe cleaning is to ensure that piping systems remain efficient, safe, and hygienic during long-term use. Its importance extends to multiple fields such as industry, construction, medical care, and daily life. Medical / food piping: removes bacteria, mold, and biofilms (such as Legionella) to prevent cross-infection or food contamination (e.g., beverage bottling pipes require regular CIP cleaning). Drinking water systems: removes scale and algae to ensure water quality meets hygiene standards (e.g., tap water pipes are cleaned quarterly) and eliminates safety hazards. Chemical piping: removes residual chemicals or reaction products to prevent accidental reactions (e.g., polymerization and agglomeration causing pipe bursts). Gas piping: removes rust and deposits to reduce the risk of leaks.

[0003] The existing technical solutions mentioned above have the following drawbacks: the brush heads of the cleaning brushes used in existing pipes are not convenient to replace quickly. Once the bristles are severely damaged and cannot be used, the entire cleaning brush must be replaced, which is too costly. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning brush for the inner wall of pipes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pipe inner wall cleaning brush includes a connecting plate. A first mounting base and a screw are fixedly connected to the outer side of the connecting plate. A first insertion hole is opened inside the first mounting base. A cover plate is installed on the outer side of the screw. A nut is sleeved on the outer side of the screw. A connecting rod is inserted into the first insertion hole. Brush bristles are installed on the outer side of the connecting rod. A connector is fixedly connected to the outer side of the connecting plate. A spring rod is fixedly connected to the outer side of the connector.

[0007] By adopting the above technical solution, an additional mounting structure is added to the outside of the connecting plate, which allows the connecting rod with bristles to be installed and assembled. The connecting rod is installed with the first mounting base, and the upper end of the connecting rod is installed through the second mounting base on the outside of the cover plate. At the same time, the cover plate cooperates with the screw on the outside of the connecting plate, and then the cover plate is locked and fixed by two nuts, so that the connecting rod can be fixed and disassembled and assembled at any time, making it convenient to replace the brush head.

[0008] Furthermore, a second mounting base is fixedly connected to the outer side of the cover plate, the second mounting base has a second insertion hole inside, and the cover plate has a through hole inside.

[0009] By adopting the above technical solution, the cover plate limits the position of the upper end of the connecting rod, making installation convenient.

[0010] Furthermore, the inner diameter of the first socket is the same as that of the second socket, and one end of the connecting rod on the outside is inserted into the inside of the second socket.

[0011] By adopting the above technical solution, it is ensured that both the upper and lower ends can be plugged into the connecting rod, making it easy to use.

[0012] Furthermore, one end of the screw extends through the through hole to the outside of the cover plate, and two nuts are provided, which are respectively placed at both ends of the outside of the cover plate, and the nuts and the screw are threadedly connected.

[0013] By adopting the above technical solution, operation and use are facilitated, and the overall structure is easy to assemble and disassemble.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] The device employs a connecting plate, a first mounting base, a second mounting base, a cover plate, a screw, a nut, and a connecting rod. The connecting rod with bristles is installed with the first mounting base, and then the other end of the connecting rod is engaged with the second mounting base on the outside of the cover plate. The other side of the cover plate is fitted onto the outside of the screw, and the cover plate is locked in place with a nut, thus allowing the connecting rod to be fixed in place. The overall structure is easy to disassemble and assemble, and the connecting rod with bristles can be removed and replaced at any time, resulting in a convenient disassembly and assembly effect.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1-5 The pipe inner wall cleaning brush includes a connecting plate 1. A first mounting base 2 and a screw 4 are fixedly connected to the outer side of the connecting plate 1. A first insertion hole 3 is opened inside the first mounting base 2. A cover plate 5 is installed on the outer side of the screw 4. A nut 6 is sleeved on the outer side of the screw 4. A connecting rod 7 is inserted into the first insertion hole 3. Brush bristles 8 are installed on the outer side of the connecting rod 7. A connecting piece 9 is fixedly connected to the outer side of the connecting piece 9. A spring flexible rod 10 is fixedly connected to the outer side of the connecting piece 9. A second mounting base 51 is fixedly connected to the outer side of the cover plate 5. The inner side of the second mounting base 51... The cover plate 5 has a second insertion hole 52 and a through hole 53 inside. An additional mounting structure is added to the outside of the connecting plate 1 to install and assemble the connecting rod 7 with bristles 8. The connecting rod 7 is installed with the first mounting seat 2. The upper end of the connecting rod 7 is installed through the second mounting seat 51 on the outside of the cover plate 5. At the same time, the cover plate 5 cooperates with the screw 4 on the outside of the connecting plate 1. The cover plate 5 is then locked and fixed by two nuts 6, so that the connecting rod 7 can be fixed and disassembled and assembled at any time, making it convenient to replace the brush head.

[0024] like Figure 1-5 As shown, the inner diameter of the first insertion hole 3 is the same as the inner diameter of the second insertion hole 52. One end of the connecting rod 7 is inserted into the inside of the second insertion hole 52. One end of the screw 4 extends through the through hole 53 to the outside of the cover plate 5. There are two nuts 6, which are respectively placed at both ends of the outside of the cover plate 5. The nuts 6 and the screw 4 are threadedly connected.
