Description

Technical Field

[0001] This utility model relates to the field of drainage hose technology, specifically to a tensile-resistant drainage hose. Background Technology

[0002] Flexible drainage pipes are made of cast iron or polymer materials. They can be divided into two categories according to the material: cast iron pipes and plastic pipes. Cast iron flexible drainage pipes have the characteristics of high strength, low noise, long service life, flame retardancy, fire resistance, and flexible shock resistance. Their interface forms are divided into flexible interfaces and rigid interfaces. Drainage hoses need to have tensile strength. The core is to cope with the unavoidable external tensile forces in actual applications, avoid pipe breakage, deformation or sealing failure, and ultimately ensure the stability, safety and service life of the drainage system.

[0003] Chinese patent CN222458861U discloses a tensile-resistant drainage hose. When the hose body is pulled, a slider moves within a groove. The slider and groove work together to limit the maximum stretch of the hose body, preventing damage from excessive stretching and improving the hose's tensile strength and the drainage system's operating efficiency. As the slider moves within the groove, a compression spring and a telescopic rod perform corresponding stretching movements. After stretching the hose body, the compression spring's force drives the telescopic rod to retract, causing the hose body to return to its original position. This prevents deformation and damage during stretching, extending the hose's service life and improving its tensile strength and drainage system's operating efficiency.

[0004] Although the above solution uses a combination of sliders, grooves, springs and other structures to set an elastic tensile limit on the hose body, the operating environment of the drainage hose will generate tension continuously or intermittently. The hose joint will be the first to be affected. When the pipe body is not tensile enough, the joint will be pulled off and the sealing rubber ring will be deformed, which will lead to water leakage at the interface.

[0005] Therefore, this utility model provides a tensile-resistant drainage hose to solve the above problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a tensile-resistant drainage hose to solve the problem that the drainage hose is used in an environment where tensile forces are generated continuously or intermittently. The hose joint is the first place to be affected. When the tensile strength of the hose body is insufficient, the joint will be pulled off and the sealing rubber ring will be deformed, which will lead to water leakage at the interface.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A tensile-resistant drainage hose includes a hose segment, both ends of which are fixedly connected to an installation segment. Each of the two installation segments is equipped with a connector segment and a movable plate. Each movable plate has detachably mounted extension segments arranged in a circumferential array. Each extension segment has a groove, and a stop plate is slidably connected within the groove. A limit nut is threaded onto each installation segment, and the limit nut limits the movable plate within the installation segment.

[0009] Preferably, a limiting ring is fixedly connected to both of the installation sections, and the limiting ring is located at the connection between the hose section and the installation section.

[0010] Preferably, the outer side of the hose segment is provided with tensile strips arranged in a circumferential array, and the two ends of the tensile strips are respectively fixedly connected to the two installation segments.

[0011] Preferably, the movable plate has a positioning groove, one end of the extension section is inserted into the positioning groove, and the movable plate is also threaded with a locking bolt, one end of which is threaded onto the extension section.

[0012] Preferably, an adjusting screw is rotatably connected to the extension section, and a linkage plate is threadedly connected to the adjusting screw, with one end of the linkage plate fixedly connected to the abutment plate.

[0013] Preferably, the tensile strip is made of a flexible material.

[0014] Preferably, the movable plate has a through hole, and the movable plate is slidably connected to the mounting section through the through hole.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. A controllable sliding space is created for the movable plate on the installation section by means of the limiting ring and the joint section. The extension section on the movable plate can directly abut against the external pipe joint through the abutment plate, and then the position of the movable plate is locked by the limiting nut. The tensile force borne by the joint is distributed to the installation section and the extension section. Moreover, the adjusting screw on the extension section can drive the abutment plate to slide in the groove, flexibly adjusting the abutment length to adapt to different specifications of external joints. This ensures that a tight abutment and tensile reinforcement can be achieved regardless of the size of the external joint, which greatly improves the safety of the drainage system.

[0017] 2. By setting flexible tensile strips in a circumferential array on the outside of the flexible rubber hose section and fixing both ends to the installation section, a tensile layer is formed around the hose section, which improves the tensile strength of the hose section itself. It can effectively resist continuous or intermittent external force stretching in actual applications, avoid the pipe body from breaking or deforming due to insufficient tensile strength, and ensure the stability of the drainage system from the root.

[0024] The following will refer to the attached reference. Figures 1 to 5 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0025] A tensile-resistant drainage hose includes a hose segment 1, both ends of which are fixedly connected to an installation segment 2. The hose segment 1 and the installation segment 2 are integrally formed. The hose segment 1 is made of flexible rubber. Tensile strips 4 arranged in a circumferential array are provided on the outside of the hose segment 1, and both ends of the tensile strips 4 are fixedly connected to the two installation segments 2 respectively.

[0026] In order to improve the tensile strength of the hose segment 1, tensile strips 4 arranged in a ring are provided on the outer surface of the hose segment 1. Multiple tensile strips 4 are used to form a tensile layer on the outside of the hose segment 1, thereby improving the tensile strength of the hose segment 1.

[0027] The tensile strip 4 is made of flexible material. In order to improve the tensile strength of the hose segment 1 while ensuring its flexibility and bendability, the tensile strip 4 is made of flexible material and can be bent synchronously with the hose segment 1 when it is bent.

[0028] Both installation sections 2 are equipped with connector sections 3, and both installation sections 2 are equipped with movable plates 6. The movable plates 6 have through holes 14 and are slidably connected to the installation sections 2 through the through holes 14. Both installation sections 2 are fixedly connected with limit rings 5, and the limit rings 5 ​​are located at the connection between the hose section 1 and the installation section 2.

[0029] The limiting ring 5 and the connector section 3 form a limiting block in the mounting section 2, so that when the moving plate 6 slides on the mounting section 2 through the through hole 14, it is restricted to a space by the connector section 3 and the limiting ring 5. Within this space, the moving plate 6 can be adjusted and moved.

[0030] The movable plate 6 is detachably mounted with an extension section 7 arranged in a circular array. The movable plate 6 has a positioning groove 12, and one end of the extension section 7 is inserted into the positioning groove 12. The movable plate 6 is also threaded with a locking bolt 13, and one end of the locking bolt 13 is threaded onto the extension section 7.

[0031] When it is necessary to disassemble the extension section 7, the locking bolt 13 can be screwed off the extension section 7 to release the limit on the extension section 7. One end of the extension section 7 can be pulled out from the positioning groove 12. When installing the extension section 7, the positioning groove 12 is used to position the extension section 7, and then the locking bolt 13 is used to fix the extension section 7 to the moving plate 6.

[0032] Each extension section 7 is provided with a sliding groove 8, and a backing plate 9 is slidably connected in the sliding groove 8. A limit nut 15 is threadedly connected to the installation section 2, and the limit nut 15 limits the moving plate 6 in the installation section 2.

[0033] When reinforcing the pipe connection, the joint section 3 is connected to the external pipe joint, and one end of the abutment plate 9 is positioned above the external joint. After the movable plate 6 moves on the installation section 2, the abutment plate 9 is placed against the external joint. After the limit nut 15 moves on the installation section 2, it abuts against the movable plate 6. The movement of the movable plate 6 is released, which blocks the direction of the joint part and achieves the effect of tensile resistance between the joint section 3 and the external joint.

[0034] An adjusting screw 10 is rotatably connected to the extension section 7, and a linkage plate 11 is threadedly connected to the adjusting screw 10. One end of the linkage plate 11 is fixedly connected to the abutment plate 9.

[0035] When it is necessary to adjust the length of the abutment plate 9 against the external joint, the adjusting screw 10 can be rotated to move the linkage plate 11 on the adjusting screw 10 and drive the abutment plate 9 to slide in the slide groove 8, thereby adjusting the length of the abutment plate 9 against the external joint.
