[0036] Reference Figure 1~Figure 5, which is the first embodiment of the utility model, proposes a hose connector for connecting a rubber hose, comprising: a core rod 1; a plurality of first annular clamping teeth 6, which are spaced apart on the outer wall of the core rod 1 along the axial direction of the core rod 1; a sleeve 2, which has a cavity 3, and the sleeve 2 is slidably arranged on the core rod 1, and an annular buckling groove is formed between the inner wall of the sleeve 2 and the outer wall of the core rod 1, and the annular buckling groove is used to clamp the rubber hose; a sliding plate 8, which is slidably arranged on the outer wall of the core rod 1, and the sliding plate 8 has a clamping strip 9, and the clamping strip 9 is used to clamp the rubber hose.

[0037] In the above scheme, the core rod 1 is the main part of the joint, and its length and diameter are designed according to the specifications of the connected rubber hose. The outer wall of the core rod 1 is processed with a specific structure to adapt to the assembly of subsequent components. A number of first annular clamping teeth 6 are arranged at intervals along the axial direction on the outer wall of the core rod 1. These clamping teeth are designed to be barbed or serrated to increase the friction with the contact surface of the rubber hose and prevent sliding. The number and spacing of the clamping teeth are optimized according to the diameter of the hose and the required grip. The sleeve 2 is designed as a hollow structure, which can be slidably sleeved on the core rod 1 and form an annular buckling groove with the outer wall of the core rod 1. The inner wall of the sleeve 2 is precisely processed to ensure a close fit with the outer wall of the core rod 1, forming a stable annular space to accommodate the rubber hose, which is convenient for the installation and fixation of the rubber hose. The sliding plate 8 is also slidably arranged on the outer wall of the core rod 1, and the relative position with the sleeve 2 is adjustable. A clamping strip 9 is provided on the sliding plate 8, and the function of the clamping strip 9 is to further clamp the rubber hose, form a double insurance with the first annular clamping teeth 6, and enhance the fixing effect. The position of the sliding plate 8 can be adjusted by simple operation to adapt to rubber hoses of different diameters, ensuring that the clamping strip 9 fits tightly to the hose.

[0038] Operation method: Insert the end of the rubber hose into the annular snap-fit ​​groove formed by the core rod 1 and the sleeve 2 until it reaches the predetermined position. Adjust the position of the sliding plate 8 to ensure that the clamping strip 9 can fit tightly against the surface of the rubber hose. The rubber hose is doubly fixed by the joint action of the clamping strip 9 of the sliding plate 8 and the first annular clamping tooth 6 on the core rod 1. Alternatively, the position of the sleeve 2 can be adjusted by appropriate tools or manually to make the entire connection tighter and more stable. Advantages: The hose joint design of this embodiment significantly improves the fixing stability of the rubber hose through the double clamping design of the first annular clamping tooth 6 on the core rod 1 and the clamping strip 9 on the sliding plate 8, thereby avoiding the problem of loose connection after long-term use. At the same time, the adjustable design of the sliding plate 8 enables the joint to adapt to rubber hoses of different specifications, improves versatility and convenience, reduces installation difficulty, and ensures the safety and efficiency of fluid transmission.

[0039] Furthermore, it also includes: a plurality of second annular teeth 7 , which are arranged on the inner wall of the sleeve 2 at intervals along the axial direction of the sleeve 2 .

[0040] In the above scheme, the second annular latch teeth 7: a plurality of second annular latch teeth 7 are arranged at intervals along the axial direction on the inner wall of the sleeve 2. These latch teeth correspond to the first annular latch teeth 6 on the core rod 1 and are designed to be complementary in shape. For example, when the sleeve 2 slides into place, the second annular latch teeth 7 contact the other side of the rubber hose to form a second latching point. They can be barbs or serrated structures similar to the first annular latch teeth 6, which are intended to penetrate into the surface of the rubber hose and provide additional gripping force. By adding the second annular latch teeth 7, the hose joint forms a double-layer latching structure inside the rubber hose, which is not only fixed from the outside by the core rod 1 and the sliding plate 8 and the clamping strip 9, but also reinforced by the second annular latch teeth 7 of the sleeve 2 inside the hose, which greatly improves the stability of the joint during use and effectively prevents loosening or falling off caused by vibration or pressure fluctuations. The presence of the second annular latch teeth 7 increases the compression deformation of the rubber hose and forms a tighter sealing effect, especially when transmitting high pressure or liquids and gases with high sealing requirements, which can effectively prevent leakage and improve the safety and efficiency of the system. Due to the combined use of the second annular latch 7 and the first annular latch 6, the joint is more adaptable to rubber hoses of different hardness and sizes. Even when the hose expands or contracts slightly, it can still maintain a good fixed and sealed state, thereby improving the versatility and service life of the joint. During the installation process, first insert the rubber hose into the preliminary buckle groove formed by the core rod 1 and the sleeve 2, then adjust the sliding plate 8 to the appropriate position, and finally ensure that the second annular latch 7 is fully engaged with the rubber hose by slightly rotating or pushing and pulling the sleeve 2 to complete the entire installation step. After installation, it is recommended to conduct a sealing test to verify whether the joint has achieved the expected sealing effect and ensure safety and reliability in actual use.

[0041] Furthermore, the first annular latch tooth 6 and the second annular latch tooth 7 are arranged in a staggered manner.

[0042] In the above scheme, the first annular latch teeth 6 are arranged along the outer wall of the core rod 1, while the second annular latch teeth 7 are arranged along the inner wall of the sleeve 2, and the two are arranged in a staggered or dislocated manner in the axial direction. When the rubber hose is clamped from the outside by the first annular latch teeth 6, its interior will be fixed again by the second annular latch teeth 7 at a slightly offset position, forming a cross-locking effect. The dislocated arrangement enables each set of latch teeth to penetrate into different positions of the rubber hose, thereby forming more contact points and support points in the circumference of the hose, significantly enhancing the overall gripping force and fixing strength, and maintaining the stability of the connection even under extreme dynamic loads or pressure changes. The staggered latch teeth layout not only increases the squeezing of the hose by generating staggered indentations on the inner and outer surfaces of the rubber hose, but also further improves the integrity of the sealing interface, effectively preventing the leakage of the medium, and is particularly suitable for the transmission of high-pressure or sensitive fluids. The dislocated arrangement can also disperse the stress distribution, avoiding excessive local stress of the rubber hose caused by excessive concentration of latch teeth at a single position, thereby reducing the risk of damage to the hose due to fatigue and extending the service life. During installation, the user needs to ensure that the rubber hose is properly aligned between the two sets of teeth, taking advantage of the staggered arrangement. The hose can be initially fixed with the first annular teeth 6 of the core rod 1, and then the sleeve 2 can be carefully slid into position, and the corresponding positions of the second annular teeth 7 and the rubber hose can be adjusted to ensure that the two sets of teeth are staggered and bite to achieve the best fixing effect. Regularly check the tightness of the joint to ensure that the staggered teeth are still in a good bite state. If necessary, the position of the sliding plate 8 or the sleeve 2 can be appropriately adjusted to maintain the high performance of the joint.

[0043] Furthermore, the cross sections of the first annular latch tooth 6 and the second annular latch tooth 7 are both straight triangles or right-angled trapezoids.

[0044] In the above scheme, the cross-sections of the first annular clamping teeth 6 and the second annular clamping teeth 7 are precisely processed in strict accordance with the standards of a straight triangle or a right-angled trapezoid during the manufacturing process. When designing the straight triangle, it is ensured that the hose is easily pressed and a firm grip is formed; the right-angled trapezoid needs to pay attention to the ratio of the wide bottom to the narrow top to achieve the self-locking effect. The use of corrosion-resistant and high-strength materials for processing ensures the stability and durability of the clamping teeth in long-term use. First, align the rubber hose correctly with the first annular clamping teeth 6 on the core rod 1, and use one end of the clamping teeth to gently squeeze the hose to ensure preliminary fixation. Then, slide the sleeve 2 along the core rod 1 to the specified position, at which time the second annular clamping teeth 7 are in contact with the inner wall of the hose. Due to the misaligned arrangement of the clamping teeth, the second annular clamping teeth 7 will find a new bite point on the hose, and the operator should slowly adjust the sleeve 2 until a clear clamping is felt. For the straight triangle clamping teeth, ensure that the tip is fully embedded in the hose; for the right-angled trapezoidal clamping teeth, confirm that the wide bottom surface fits the inner wall of the hose, and use the self-locking effect to strengthen the fixation. After installation, check the stability of the joint by gently pulling the hose to ensure that the teeth are fully engaged. Check the teeth regularly for wear or damage. If severe wear is found, replace the joint in time to maintain the sealing and safety of the system. In high-pressure or frequent use environments, check the tightness of the joint regularly and adjust the sliding plate 8 or sleeve 2 if necessary to maintain the best clamping state. Through the above implementation method, the straight triangle or right-angled trapezoidal cross-section design of the first annular tooth 6 and the second annular tooth 7 is fully utilized, which not only improves the fixing efficiency and sealing of the hose joint, but also enhances its stability and durability in complex working environments.

[0045] Furthermore, the core rod 1 has a through hole 4 , and the through hole 4 is arranged inside the core rod 1 along the axial direction of the core rod 1 .

[0046] In the above solution, when the rubber hose and the hose joint are connected, the through hole 4 is convenient for the flow of liquid and gas.

[0047] Furthermore, the core rod 1 has a slide groove 5 , and there are a plurality of slide grooves 5 , which are arranged along the axis direction of the core rod 1 and are spaced apart on the circumference of the outer wall of the core rod 1 ; the sliding plate 8 is slidably disposed in the slide groove 5 .

[0048] In the above scheme, a number of slide grooves 5 are arranged on the outer wall of the core rod 1 along the axial direction. These slide grooves 5 are for accommodating the sliding of the sliding plate 8 so that the sliding plate 8 can move axially on the core rod 1. The number and spacing of the slide grooves 5 are carefully calculated according to the size and design requirements of the joint to ensure that the sliding plate 8 can move flexibly within the necessary range without affecting the overall stability of the joint. The sliding plate 8 is designed to be slidably embedded in these slide grooves 5. By cooperating with the core rod 1, the sliding plate 8 can slide freely in the slide groove 5 along the axial direction of the core rod 1, thereby adjusting the position. A clamping strip 9 is arranged on the sliding plate 8 for clamping the rubber hose. As the position of the sliding plate 8 changes, it can adapt to hoses of different diameters or adjust the clamping degree as needed.

[0049] Furthermore, the sliding plate 8 has a plurality of grooves 801, which are arranged at intervals on the sliding plate 8, and a clamping strip 9 is arranged in each groove 801, one end of the clamping strip 9 is arranged on the inner wall of the groove 801, and the other end of the clamping strip 9 is located in the groove 801, and the clamping strip 9 is arranged inclined toward the sleeve 2.

[0050] In the above scheme, a plurality of spaced grooves 801 are provided on the sliding plate 8, and these grooves 801 are arranged along the length direction of the sliding plate 8, providing accurate position and direction guidance for the placement of the clamping strip 9. The distribution of the grooves 801 is coordinated with the slide grooves 5 on the core rod 1 to ensure that each clamping strip 9 is accurately positioned when the sliding plate 8 slides. A clamping strip 9 is provided in each groove 801, one end of which is fixed on the inner wall of the groove 801, and the other end is arranged obliquely toward the sleeve 2. This inclined design enables the clamping strip 9 to form an oblique supporting force when it contacts the rubber hose, which not only increases the clamping force, but also helps to resist the displacement caused by pressure or vibration, further improving the sealing effect. The inclined arrangement of the clamping strip 9 not only increases the clamping force, but also makes the clamping tighter, effectively preventing fluid leakage, and is particularly suitable for high-pressure or dynamic application environments.

[0051] Furthermore, the core rod 1 also includes: a plurality of fixed blocks 10 , which are arranged in the slide groove 5 at intervals, each fixed block 10 is located in a groove 801 , and the clamping strip 9 is slidably abutted against the fixed block 10 .

[0052] In the above scheme, a plurality of fixing blocks 10 are arranged at intervals in the slide groove 5 of the core rod 1, and each fixing block 10 is located in a groove 801. When the clamping strip 9 moves toward the fixing block 10, the inclined clamping strip 9 is squeezed by the fixing block 10, and the clamping strip 9 is tilted and deflected toward the sleeve 2, thereby squeezing and tightening the rubber hose.

[0053] Furthermore, it also includes: a push rod 11, one end of which is arranged on the top of the inner wall of the sleeve 2, and the other end is arranged on the end of the sliding plate 8. After the sleeve 2 slides, the push rod 11 is used to push the sliding plate 8 to slide along the sliding groove 5.

[0054] In the above scheme, the push rod 11 is arranged on the sleeve 2. When the sleeve 2 is pressed down, the push rod 11 pushes the sliding plate 8 to move, realizing the linkage between the sliding plate 8 and the push rod 11, and further enhancing the convenience of adjusting the sliding plate 8. It should also be noted that after the sleeve 2 moves, it is fixedly connected to the outer wall of the core rod 1 by a fastener, such as a clamp or a bolt.

[0055] Furthermore, the fixing block 10 and the first annular locking tooth 6 are arranged in a staggered manner.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
