[0031] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For example, see Figures 1 to 6 The present invention provides a technical solution: a high-pressure flexible rubber hose comprises a rubber inner layer 1, a steel mesh cover 2 is fixedly sleeved on the outer side of the rubber inner layer 1, a rubber outer layer 3 is fixedly sleeved on the outer side of the steel mesh cover 2, a rubber diaphragm 5 is provided on the inner ring surface of the rubber inner layer 1, one end of the rubber diaphragm 5 is plugged into the inner ring surface of the rubber inner layer 1, a reserved groove 4 is provided on the inner ring surface of the rubber inner layer 1, the reserved groove 4 is an arc-shaped groove, the other end of the rubber diaphragm 5 is fixed to the surface of the reserved groove 4, the reserved groove 4 and the rubber diaphragm 5 match, the rubber diaphragm 5 is in the form of an arc sheet after being pushed into the reserved groove 4, and the inner ring diameter of the rubber diaphragm 5 in the form of an arc sheet is equal to the inner ring diameter of the rubber inner layer 1; after the rubber diaphragm 5 is pushed into the reserved groove 4, the anti-dropping limit is realized by connecting the first clamp, and after the rubber diaphragm 5 is pulled out of the reserved groove 4, it is plugged into the inner ring surface of the rubber inner layer 1 by connecting the second clamp; the connecting clamp Component 1 includes a rubber strip 9 and a second card slot 10. The rubber strip 9 is a long strip with a circular end face. The rubber strip 9 is integrally formed on the surface of the rubber partition 5. There are multiple rubber strips 9, and the multiple rubber strips 9 are equidistant and equal in size on the surface of the rubber partition 5. The second card slot 10 matches the rubber strip 9, and the second card slot 10 and the rubber strip 9 correspond one to one. After the rubber partition 5 is pushed into the reserved groove 4, the second card slot 10 is inserted into the corresponding rubber strip 9; the connecting card component 2 includes a plastic strip 6, a card slot 1 7 and a rubber sleeve 8. The plastic strip 6 is fixed at one end of the rubber partition 5, and the rubber sleeve 8 is sleeved on the end of the plastic strip 6 away from the rubber partition 5. The card slot 1 7 is opened on the inner ring surface of the rubber inner layer 1. The card slot 1 7 is a groove body with a circular cross section, and the rubber sleeve 8 is a long strip with a circular cross section. After the rubber partition 5 is pulled out of the reserved groove 4 and unfolded, the plastic strip 6 and the rubber sleeve 8 are both inserted into the card slot 1 7.

[0033] When in use, the rubber partition 5 is installed inside the rubber inner layer 1 to facilitate the isolation of two spaces in the rubber inner layer 1. After the two spaces are divided into zones, it is convenient to classify and organize the structures plugged in the rubber inner layer 1. That is, when it is necessary to divide the rubber inner layer 1 into zones, the rubber partition 5 is pulled out from the reserved groove 4, and the plastic strip 6 and rubber sleeve 8 at one end of the rubber partition 5 are pushed into the card slot 1 7. At this time, the rubber sleeve 8 is stuck in the card slot 1 7, that is, the rubber partition 5 is unfolded to divide the space inside the rubber inner layer 1; if it is not necessary to divide the rubber inner layer 1 into zones, the plastic strip 6 is pulled out to drive the rubber sleeve 8 to be pulled out from the card slot 1 7, and then one end of the reserved groove 4 is connected to the rubber partition 5, and the rubber partition 5 is pushed into the reserved groove 4 along the rubber partition 5 until the rubber partition 5 is completely pushed into the reserved groove 4. At this time, the rubber strip 9 is squeezed and pushed into the card slot 2 10, so as to realize the anti-slip limit after the rubber partition 5 is pushed into the reserved groove 4.

[0034] A pressure-resistant plane 11 is provided on the outer ring surface of the rubber inner layer 1. The long side length of the pressure-resistant plane 11 is equal to the long side length of the rubber outer layer 3. Four pressure-resistant planes 11 are provided. The four pressure-resistant planes 11 are distributed in a circle with the rubber outer layer 3 as the central axis. A rubber pad 12 is fixed on the surface of the pressure-resistant plane 11. The rubber pad 12 is an arc-shaped strip. The long side length of the rubber pad 12 is equal to the long side length of the pressure-resistant plane 11. The outer ring diameter of the rubber pad 12 is equal to the outer ring diameter of the rubber outer layer 3. A through opening 13 is opened on the surface of the rubber pad 12. A rubber support strip 14 is fixed inside the through opening 13.

[0035] When in use, a pressure-resistant plane 11 is provided on the outer annular surface of the rubber outer layer 3 so that when the rubber outer layer 3 contacts the ground and an object presses down on the rubber inner layer 1, the contact area between the pressure-resistant plane 11 and the ground and the object is large, thereby making the entire high-pressure flexible rubber hose have good pressure resistance; and a buffer structure composed of a rubber pad 12 and a rubber strut 14 is fixed on the surface of the pressure-resistant plane 11, which plays a buffering role when the rubber outer layer 3 touches the ground, and the rubber pad 12 and the rubber strut 14 are deformed under pressure to ensure that the ground contact area of ​​the pressure-resistant plane 11 after being compressed is only a straight line compared to the circular line body. The setting of the pressure-resistant plane 11, the rubber pad 12 and the rubber strut 14 ensures that the entire high-pressure flexible rubber hose has good pressure resistance.

[0036] The outer ring surface of the rubber outer layer 3 is provided with tensile grooves 15 , and there are multiple groups of tensile grooves 15 . Each group of tensile grooves 15 is distributed alternately with the compression plane 11 , and there are multiple tensile grooves 15 in each group, and the long side length of the tensile grooves 15 is equal to the long side length of the rubber outer layer 3 .

[0037] Detailed summary of the use process of high-pressure flexible rubber hose:

[0038] Ensure that the hose has no signs of damage, deformation or aging. Check whether the rubber partition 5 is intact, and whether the connection card 1 (rubber strip 9 and slot 2 10) and the connection card 2 (plastic strip 6, slot 1 7, rubber sleeve 8) are functioning properly. Determine whether the rubber inner layer 1 needs to be divided into spaces as needed. Assess the pressure and tension that the hose may be subjected to and ensure that the hose can withstand the expected working environment.

[0039] When dividing the space: Gently pull the plastic strip 6 to drive the rubber sleeve 8 to be pulled out from the inner ring surface groove 7 of the rubber inner layer 1. Pull the rubber partition 5 out of the reserved groove 4 completely to unfold it. Align one end of the rubber partition 5 (with the plastic strip 6 and the rubber sleeve 8) with the inner ring surface groove 7 of the rubber inner layer 1. Push the plastic strip 6 and the rubber sleeve 8 to fully insert them into the groove 7 to fix the rubber partition.

[0040] When the space is not divided: pull out the plastic strip 6 and the rubber sleeve 8 from the card slot 1 7 to make the rubber partition 5 movable. Slowly push the rubber partition 5 into the reserved groove 4 along the connection end between the rubber partition 5 and the reserved groove 4. Make sure that the rubber strip 9 is completely squeezed into the card slot 2 10 to achieve the anti-drop limit of the rubber partition.

[0041] At the position where the hose may touch the ground, ensure that the compression surface 11 is in contact with the ground. The rubber pads 12 and rubber stays 14 on the compression surface 11 will provide additional cushioning and support to reduce the deformation of the hose when it is compressed. When the hose is subjected to tension, the tension grooves 15 will disperse the tension and reduce the risk of the hose being damaged due to excessive tension. Ensure that the tension grooves 15 are distributed alternately with the compression surface 11 to provide balanced tension resistance.
